[0012] The threshing and stem-breaking drum, threshing box, crushing roller, group railing, threshing drum and threshing nails are provided to achieve the effect of automatic threshing. Under the driving cooperation of the conveyor belt, the harvested lentils can be effectively conveyed to the threshing and stem-breaking drum. The threshing and stem-breaking drum is composed of a 12-angle crushing roller and a box body. During the rotation process, the stems and leaves of the lentils are crushed for the second time to facilitate the later threshing. The threshing drum is composed of a threshing roller composed of 6 groups of 16 threshing nails in each group, and cooperates with a separation shell equipped with a transverse threshing cylinder to complete the threshing, and the beans are completely separated from the bean shells. The bean shells, stems and leaves, and beans are all sent out from under the threshing roller, thereby improving the threshing efficiency.
[0013] The screening of beans is achieved by providing an air cylinder, an air pipe, a screening mechanism and a chute. The operation of the driving motor 1 drives the crank rocker assembly, and cooperates with the limit of the sleeve to make one side of the crank rocker assembly form a linear reciprocating movement, pull the guide plate, and drive the screen frame to move synchronously. The screen frame swings left and right by cooperating with the slide rails on both sides, and the beans fall from the 4.5 diameter sieve holes inside the screen frame. At the same time, the air cylinder with 12 fan blades next to it blows away the lighter stems and leaves on the screen, completing the overall threshing and cleaning effect.
[0014] The harvesting distance can be adjusted by setting up a cutting table, an ultrasonic ranging sensor, a mounting frame, a telescopic rod and an electric push rod. The front end of the cutting table adopts ultrasonic ranging to control the telescopic push of the electric push rod through single-chip calculation. With the cooperation of the slide and the connecting column, the distance between the five-blade spiral roller and the ground is controlled. In the continuously undulating mountainous area, the distance between the cutting table and the ground can be better controlled and determined between 60 and 80 mm. The harvesting accuracy is greatly improved, and the precise adjustment of parameters such as harvesting depth and harvesting speed can be achieved. In addition, since the blade is set to a spiral shape, it is helpful to roll the cut lentil plants into the transmission mechanism, and the spiral blade wheel can prevent entanglement.
