Backpack harvester
The backpack harvester uses a flexible shaft for transmission. The general structure is similar to the side brush cutter. The difference is that the engine is carried on the operator's back, and the cutting parts are driven by a flexible shaft. The engine power is usually 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 installed in a hose to transmit torque. The hose is a threaded tube wrapped in a metal braid covered with a rubber protective sleeve to prevent dust from entering the shaft and keep the lubricating oil on the shaft surface. The cutting width is usually 1.5 to 2 meters.
The walking harvester is supported by the running wheels, and the machine is pushed forward by people, and the engine drives the working parts to complete the cutting and sweeping operations. Its structure china number data and working principle are similar to those of the portable brush cutter. The hanging harvester is suspended behind the tractor, and the working parts are driven by the power take-off shaft. It is suitable for large-scale brush cutting operations. It is mainly composed of a frame, a saw blade, a transmission device, a hanging device and a pushing plate. During the brush cutting operation, the tractor moves backward, the working speed is 5 km / h, and the brush with a diameter of 10 cm can be cut.
Horizontal combine harvester
The horizontal combine harvester consists of a reel, one or two canvas conveyor belts, a straw separator, a cutter and a transmission device. During operation, the reciprocating cutter cooperates with the reel pressure plate to cut the crop and push it back onto the canvas conveyor belt, which then delivers the crop to the left side of the machine.
