As technology improved, more advanced corn harvesters appeared in the early 20th century. These machines use an internal combustion engine as their power source to harvest corn more efficiently. One of the common designs is to lift the corn plant off the ground and harvest by cutting the stalk, then convey the ear of corn inside the machine for processing and storage.

The design of corn harvesters gradually improved over time

New functions were added, such as automatic control systems, adjustment devices, and more efficient conveyor belts. These improvements allow corn harvesters to complete harvesting tasks faster and more efficiently, reducing the need for human labor.Modern corn harvester has become one of the indispensable tools in agricultural production. They are able to complete a large amount of harvesting work in a short period of time and increase the productivity of farmers. As technology continues to develop, we can expect more innovative designs and features to be applied to corn harvesters in the future to further improve their efficiency and reliability.

The core technologies of the corn harvester include cutting, transmission, cleaning, control and power. With the advancement of science and technology, the core technology of corn harvester is also constantly evolving and improving. The use of new materials, the application of sensor technology, and the development of intelligent control systems have all brought higher efficiency, accuracy and reliability to corn harvesters.

1. Cutting technology

Corn harvesters need to be able to cut the stalks of corn plants accurately and efficiently so that the ears of corn can be collected smoothly. Modern corn harvesters typically employ sharp rotary knives, such as blades or saw blades, that spin rapidly to cut through the stalk.
Corn harvesters are equipped with multiple blades, usually in a helical or linear arrangement. The blades rotate rapidly to directly contact and cut the stalk of the corn plant. The shape and design of the blade will affect the cutting effect and the running stability of the machine.
Another common cutting tool is a saw blade. These saw blades usually have a serrated edge and use rapid rotation to cut the stem into small pieces. The saw blade is designed to allow the stalk to be cut off more easily and with less impact on machine vibration and noise.

The goal of cutting technology is to achieve an accurate and efficient cutting process to ensure that the ears of corn can be collected smoothly. To achieve this goal, modern corn harvesters typically combine factors such as rotational speed, shape and position of the cutting tool to maximize cutting efficiency and quality. In addition, the machine operator also needs to adjust and optimize according to the actual situation to ensure the smooth progress of the cutting process.

2. Transmission technology

The ears of corn need to be transported from the cutting location to inside the machine for processing and storage. Conveyor systems usually include conveyor belts, conveyor chains or wind conveyors, etc. These devices enable the quick and efficient transfer of ears of corn from the cutting location to storage or collection containers.
A conveyor belt is a common conveying device that conveys the ear of corn forward from the cutting position through a belt-like structure. Conveyor belts are usually made of wear-resistant materials and their operation is driven by electric or hydraulic systems. The conveyor belt can be adjusted as needed to accommodate ears of corn of different sizes and shapes.
Conveyor chain is also a commonly used transmission device, which carries and conveys ears of corn through scrapers or trays on the chain. Conveyor chains are usually made of wear-resistant materials for high strength and durability. Conveyor chains provide better control over the position and orientation of the ears of corn during transport than conveyor belts.

Conveyors to transport for corn

Some corn harvesters use wind conveyors to transport the ears of corn. This device uses the force of the wind to blow the ears of corn inside the machine. The wind conveying device is usually equipped with a fan or fan, which can control the conveying speed and path of the ear of corn by adjusting the wind force and direction.
Conveyor technology is designed and optimized for fast, efficient ear conveyance to increase harvest efficiency and reduce human intervention. In addition, the transfer system also needs to take into account the protection of the ears of corn and the prevention of clogging to ensure a smooth collection and storage process. Different models of corn harvesters may use different transmission technologies to suit different needs and operating environments.

3. Cleaning technology

During harvesting, corn harvesters need to be cleared of stalks, leaves and other debris to keep the machine running and prevent clogging and damage. Modern corn harvesters are equipped with cleaning systems including brushes, fans or vibrating devices to clean and separate the various parts of the corn plant.
Brushes are a common cleaning device that are installed at specific locations on corn harvesters. They rotate or vibrate to remove stalks, leaves and other debris attached to the corn plant. The bristles of the brush are usually made of a durable material that can effectively remove buildup.
The fans on corn harvesters create powerful airflows that blow away stalks, leaves, and other debris. Fans are usually located under conveyor belts or conveyor chains to blow off debris that falls on the conveyor belt. The speed and direction of the fan are adjustable to suit different scenarios and cleaning needs.

Vibrating devices

Some corn harvesters are equipped with vibrating devices that vibrate to separate stalks, leaves and other debris. The vibration device can be installed above the conveyor belt or conveyor chain, so that the sundries will automatically fall into the cleaning channel or storage container of the machine after being separated.
These cleaning devices have been designed and optimized to ensure that corn harvesters can quickly and efficiently remove stalks, leaves and other debris attached to corn plants. Through reasonable layout and adjustment, blockage and damage can be reduced, and the reliability and working efficiency of the machine can be improved. In addition, regular maintenance and cleaning are also very important to keep the cleaning system running properly.

4. Control technology

Automatic control system is an important part of modern corn harvester. Through sensors and an electronic control unit, the machine can monitor and control processes such as cutting, conveying and cleaning for precise operation and optimal harvesting results.
The corn harvester is equipped with various sensors, such as photoelectric sensors, pressure sensors, speed sensors, etc. These sensors can sense environmental conditions and machine operating status in real time, such as detecting the position and size of corn plants, monitoring the running speed and tension of conveyor belts, and detecting the pressure and vibration of machines.

The electronic control unit (ECU) is the brain of the corn harvester, which receives sensor data and analyzes and processes it according to preset algorithms. ECU can automatically adjust and control the operating parameters of cutting tools, conveyor belts, fans, etc. according to the feedback of sensor data, so as to adapt to different operating conditions and achieve the best harvesting effect.
Modern corn harvesters usually have automatic operation functions. Through preset programs and parameters, operations such as automatic start and stop, speed adjustment, and operating mode switching are realized. Machine operators can make settings and adjustments through the control panel or remote control, increasing the convenience and consistency of operation.

Control technology

Include that data acquisition and analysis functions to collect and record key data during machine operation. These data can be used for maintenance, fault diagnosis and performance optimization, etc., to help the owner or operator to better manage and maintain the corn harvester.
Through the application of control technology, modern corn harvesters can achieve precise and efficient operation, improving operational efficiency and quality. At the same time, the control technology can also provide more intelligent functions, such as automatic identification and troubleshooting, remote monitoring and management, etc., to provide users with a more convenient and reliable experience.

5. Power technology

Corn harvesters usually use an internal combustion engine (such as a diesel or gasoline engine) as a power source. These power systems need to provide sufficient driving force and energy to support the high-speed operation and high-load work of the machine.
The internal combustion engine is one of the most common sources of power, usually using a diesel or gasoline engine. These internal combustion engines burn fuel to generate power and convert it into mechanical energy that drives the various components of the corn harvester. The internal combustion engine has the characteristics of high efficiency and stability, and is suitable for long-term and high-load operations.

Some corn harvesters use electric motors as their power source. The motor converts electrical energy into mechanical energy to drive cutting tools, transmission systems and cleaning devices. Electric motors usually need to be connected to the grid or equipped with high-capacity batteries to provide sufficient power supply.
Hydraulic systems are also a common power technology used to drive various functions of corn harvesters. Hydraulic systems use the flow of fluid (usually oil) to transmit power and control the operation of machines. The hydraulic system has the characteristics of high power density and strong adjustability, and is suitable for synchronous operation of multiple working parts.

Corn harvester technology is developing in the direction of multifunctional and modular design, automation and intelligence, refined and precision agriculture, energy saving, environmental protection and sustainable development, data management and Internet applications.

Corn harvesters will be more multifunctional and modular

It able to adapt to different farmland requirements and operational needs. For example, different operation methods (such as straight cutting, cutting table, rooting) can be realized by changing different knives or attachments to adapt to different types and growth stages of corn plants.
With the application of advanced sensor technology and data processing algorithms, corn harvesters will increasingly have automated and intelligent functions. The machine can autonomously identify and adjust operating parameters to achieve precise cutting and harvesting, and improve operating efficiency and quality through learning and optimization algorithms.

Future corn harvesters will pay more attention to the application of fine and precision agriculture technology. By combining GPS, geographic information system (GIS) and remote sensing technologies, etc., machines can achieve precise positioning, path planning and job management to minimize waste and loss.
In order to reduce energy consumption and environmental impact, the corn harvester will adopt more energy-saving and environmentally friendly power solutions, such as electric motors, hybrid systems, etc. At the same time, it will also focus on reducing damage to soil and ecological environment, and reduce farmland reclamation and abuse by improving design and adopting precise operation techniques.

With the development of agricultural information technology

Future corn harvesters will be better connected with farm management systems and data platforms to achieve data sharing and remote monitoring. This will provide farmers with more decision support and management tools, improving the efficiency and sustainability of agricultural production.
In general, the future corn harvester technology will be multi-functional, automated and intelligent as the main development direction. At the same time, energy conservation and environmental protection, precision agriculture and data interconnection will also become the focus of technological development. The application of these technologies will improve the efficiency and quality of operations, reduce the labor burden of farmers, and promote the sustainable development of agriculture.
