Corn thresher manufacturer portable
It is divided into two types: side-mounted and piggyback:
The 1 side-mounted automatic harvester adopts hard shaft transmission, which is mainly composed of engine, transmission system, clutch, working parts, operating device, and side belt. A 0.75~2 kW single-cylinder two-stroke air-cooled gasoline engine and a centrifugal friction clutch are arranged at one end of the drive shaft, and the other end is equipped with a working part composed of a reducer and a cutting tool. There are many types of working parts and commonly used are circular saw blades, blades or nylon wires. During the operation, the hook ring on the aluminum alloy sleeve of the drive shaft is hung on the shoulder strap under the shoulder of the operator, and the handgrip is held, and the hard shaft is horizontally swung to complete the work of cutting weeds and shrubs. The machine weighs about 6~12 kg and the speed is about 4500~5000 rpm.
2 backpack automatic harvester. With soft shaft transmission, the general structure is similar to the side-mounted brush cutter. The difference is that the engine is backed on the operator's back, the cutting parts are driven by the flexible shaft, and the engine power is generally 0.75~1.2 kW. The engine and the back frame are connected at two points and equipped with special rubber parts for vibration isolation. The flexible shaft is a steel flexible shaft that fits inside the hose to transmit torque. The hose is a threaded tube of steel tape wrapped around a metal braided mesh covered with a rubber boot to infiltrate the shaft with dust-proof soil and retain the lubricating oil on the shaft surface. The cutting width is generally between 1.5 and 2 meters.
Walk-up
The weight of the machine is supported by the traveling wheel, and the machine pushes the machine forward, and the engine drives the working part to perform the cutting and filling operation. Its construction and working principle are similar to portable brush cutters.
hanging
Suspended behind the tractor, the power output shaft drives the rotating part of the working part, suitable for large-area cutting operations. It is mainly composed of a frame, a saw blade, a transmission, a suspension device, and a push plate. During the cutting operation, the tractor retreats at a speed of 5 km/h and can cut a shrub with a diameter of 10 cm.

Small corn thresher
In order to reduce the labor intensity and improve the work efficiency of farmers during corn threshing, corn thresher manufacturers design small corn threshers.
The overall structure of the small corn thresher is divided into:
Feeding part:
The feed port is connected to the upper cover portion of the small corn thresher. It is made of a one-centimeter thick iron plate. The feeding part is tangent to the nail tooth part of the nail toothed cylinder, and the corn which has been plucked is taken from the inlet. Enter and slide down to the threshing part, ie between the nail roller and the grid type concave plate, for threshing.
Threshing part:
The threshing part is mainly composed of a nail toothed roller, a grid type concave plate and a semicircular upper cover. The ear of corn is threshed between the nail roller and the grid concave plate, and the removed corn kernel is leaked from the gap of the grid concave plate, falls to the lower sliding plate, and is discharged from the body outside the body by the corn mouth. The other end of the feed port (ie, the discharge port) is discharged from the outside of the body by means of the helical thrust and the helical guiding action of the spiral teeth arranged on the drum.
Filter section:
The screening part is mainly done by grid gravure. It consists of a certain number of iron bars and two main beams and two sub-beams. The gap between each two iron bars can catch the corn and then rotate quickly. The nail-toothed cylinder forcibly threshes the stuck corn. Of course, the grid-type concave plate is fixed whether it is working or installed. After the corn is threshed, the corn kernels are passed through a grid of concave plates, leaking from the gaps of the concave plates, and sliding out of the body along the inclined slides, in order to separate the corn and the corn cob.
