The walking wheel 13 is internally made of profile steel, the outside is made of rubber, and a plurality of anti-slip teeth are obliquely arranged on the profile steel in the walking wheel 13. The total weight of the harvester is about 75 kg, the weight is light, and the muddy pit does not sink deeply when running, so that the harvester can completely walk in the muddy field. Because the rubber is arranged outside the travelling wheel 13, the travelling wheel can also walk on a road without damaging the road surface. The walking wheels are arranged at two ends of the walking shaft, and the walking shaft is driven by power.
The rear end of the frame 1 is also provided with a cushion 19 and a balance wheel 14 positioned below the cushion 19. During harvesting, a worker can sit on the cushion 19 to operate, so that physical effort is avoided.
The harvester of the present invention also includes a power drive section that includes an electric motor 20 and a gearbox 18 coupled to the electric motor 20. The gearbox 18 is provided with a speed-changing adjusting handle, and the speed can be manually adjusted. The gearbox 18 is connected with the travelling wheels 13 and used for controlling the forward and backward movement of the travelling wheels; the gearbox 18 is connected with the fan 17 and used for controlling the rotating speed of the fan; the gearbox 18 is connected with the reel 3 and is used for controlling the rotation speed of the reel; the gearbox 18 is connected with the threshing roller 4 and the auger 5 and is used for controlling the rotating speeds of the threshing roller and the auger; as shown in fig. 1 and 2.
The harvester of the invention works as follows:
when harvesting, the motor is started, the grain pulling roller and the threshing roller reversely rotate, the grain pulling roller pulls grain ears into the threshing roller, the threshing roller performs threshing, grains leak into the grain collecting bin from the screen mesh, are sent into the slag separating and grain collecting device through the auger, and Gu Geng falls into the ground from a re-disengaging port at the lower end of the threshing roller.
