-Working principle: By moving the vehicle, the "U" - shaped shovel tray at the front end collects corn from the ground. The auger inside the shovel tray sends the corn into the conveying channel, which is then transported to the threshing mechanism through the conveyor belt and scraper. The roller in the threshing mechanism rotates at high speed, using components such as a swinging hammer to peel off corn kernels from the corn cob. The corn cob and corn kernels are separated through a sieve, and then the dust and light impurities are blown away by a fan to complete threshing.

-Structural features: Usually equipped with a hydraulic front shovel, some models have widened front shovels to improve feeding efficiency. There are transmission channels, conveyor belts and other conveying components, as well as multiple threshing drums, such as three-axis, five axis or six axis threshing drums. Some machines are equipped with fully enclosed driver's cabins, providing a comfortable operating environment, and are equipped with telescopic suction drums and rotatable high-level unloading devices for easy unloading.

-Performance advantages: High degree of automation, automatic feeding, no need for manual feeding, saving manpower. High work efficiency, can thresh about 20 tons per hour, equivalent to 40000 pounds, and some models can thresh 60 acres of land per hour. Good threshing effect, high removal rate, and low impurity content in corn kernels. Strong mobility, able to move flexibly and adapt to different locations, such as roadsides, courtyards, etc.

-Power configuration: Generally equipped with a power of 22 horsepower or more, some large models are equipped with 120 horsepower or 130 horsepower all diesel engines, etc., with strong power to ensure stable operation of the machine.

Self- suction five axis self-propelled: The 2025 model is equipped with Xichai Sida 120 horsepower or Anhui Quanchai 130 horsepower engines, which can thresh about 20000kgs per hour. Adopting two feeding methods: wind suction feeding and spiral front shovel feeding, equipped with a fully enclosed cab, telescopic suction drum, 360 ° hydraulic rotating high-level unloading, and an enlarged corn cob bin.

Technical advantages

-Efficient threshing: can thresh 60-100 acres of land per hour with a net threshing rate of up to 100%. The six cylinder threshing machine feeds from two drums simultaneously, and the corn kernels quickly fall off under the action of the high-speed rotating shaft.

-Thoroughly clean impurities: For example, the 5TY-1250C model uses a whistle type double centrifugal suction fan to suck away dust, fuzz, and other impurities and send them into its own pocket. Part of the self-propelled corn threshers are equipped with a large fan to improve the cleaning effect and meet competitive standards.

-Various feeding methods: the wind suction feeding corn thresher adopts a dual mode of wind suction and front shovel feeding, which is capable of both road threshing and corn storage threshing.

-Easy to operate: Self propelled corn threshers are often equipped with luxurious fully enclosed cabins, providing comfortable driving and easy operation. Some also have functions such as one click intelligent control.

Design features:

Sturdy and durable, advanced production technology, reliable product quality, strong applicability. It can produce various types of corn threshers such as self-propelled and towed according to the needs of different regions, and can also be customized according to customer requirements.

(1) Feeding process

Usually equipped with a spiral front shovel or an air suction feeding device. The front shovel can directly lift corn ears from the ground and feed them into the machine through a conveyor chain or auger conveyor; Wind suction uses negative pressure to suck corn ears into the feed inlet, adapting to different stacking scenarios (such as ground and corn storage).

(2) Threshing process

The corn ear enters the threshing drum (usually a multi axis drum, such as a five axis or six axis drum), and the wear-resistant blocks, nail teeth, or ribs on the drum interact with the concave plate (fixed screen like component) during high-speed rotation, peeling the corn kernels from the ear shaft through impact, rubbing, and tearing. During the threshing process, the cob moves backwards with the rotation of the drum and is ultimately discharged from the core discharge port.

(3) Selection and Separation Process

A: Screening: The detached corn kernels, broken kernels, impurities, etc. enter the screening box (such as a double-layer specific gravity sieve), and through the vibration of the screen surface, use the differences in specific gravity and size of different materials to separate qualified corn kernels, remove broken cores, rotten seeds, etc.

B: Wind selection: equipped with multiple sets of fans, generating airflow to suck away corn leaves and light impurities (such as dust and corn whiskers), further purifying corn kernels. Some models can also collect dust to reduce pollution.

(4) Unloading process

The clean corn kernels after cleaning are transported to the grain storage bin through conveying devices such as auger conveyors and telescopic suction drums, and then unloaded to the transport vehicle through a hydraulic controlled high-level unloading device (which can rotate 360 °), completing the entire operation process.
