[0032] Wherein, the screen 409 is arranged at an incline.

[0033] Specific embodiments of the utility model:

[0034] When the operation starts, the corn ears are placed at the lower end of the lifting and conveying mechanism 1, and the first motor 102 is started. The first motor 102 drives the conveyor belt 105 through the conveying roller 103, and the corn ears are lifted to the upper side of the peeling mechanism 2 through the baffle 106 and fall into the peeling bin 201, and the second motor 204 is started. The second motor 204 drives the first driven wheel 206 and the second driven wheel 302 through the first transmission belt 207. The first driven wheel 206 drives the transmission gear 208 and the driven gear 302. The driven gear 209 drives the first peeling roller 211, and the peeling operation is performed through the active rotation of the first peeling roller 211 and the driven rotation of the second peeling roller 212. The peeled corn ears will be sent to the end of the first peeling roller 211 through the auger blades on the first peeling roller 211, and then fall into the peeling bin discharge port 213; wherein, the second driven wheel 302 will drive the impurity suction through-flow blades 303 to make the corn husks left in the peeling bin 201 fall out through the corn husk discharge port 214.

[0035] When the corn ears that have completed the peeling operation are fed into the threshing bin 401 from the threshing bin feed port 402, the third motor 403 is started, and the third motor 403 drives the third driven wheel 404 and the fourth driven wheel 405 through the second transmission belt 406, and the third driven wheel 404 and the fourth driven wheel 405 drive the first threshing roller 407 and the second threshing roller 408 respectively; since the position of the corn ears themselves is random and not parallel to the first threshing roller 407 and the second threshing roller 408, the ears are in contact with both rollers, and the part of the ears in contact with the second threshing roller 408 is acted upon by the axial component of the normal force of the mule rotation, so that the part of the ears in contact with the second threshing roller 40 The portion of the fruit ear in contact with the first threshing roller 407 moves axially, while the portion of the fruit ear in contact with the first threshing roller 407 is not acted upon by force in the axial direction, so that there is a certain degree of speed lag in this portion. In this way, the fruit ear gradually corrects its position and moves in a direction parallel to the two silver axes under the action of the rotational torque of the two rollers. With the rotation of the two rollers, the axis of the fruit ear becomes parallel to the two spoke axes. Since the two rollers rotate in the same direction, the two tangential forces at the outer edges of the two rollers in contact with the fruit ear form a rotational torque, which causes the fruit ear to rotate around its own axis, and driven by the axial component of the normal thrust of the outer edge of the spiral roller, the fruit ear moves in a direction parallel to the roller axis. Since the rotation speed of the first threshing roller 407 is greater than the rotation speed of the second threshing roller 408, the tangential linear velocity of the outer edge of the first threshing roller 407 is greater than the tangential velocity of the normal velocity of the outer edge of the second threshing roller 408, and the two rollers form differential threshing for the ears. Under the differential action of the two rollers, the kernels are threshed; after the threshing operation is completed, the corn cobs and corn kernels fall on the screen 409 together, among which the corn kernels fall through the sieve holes of the screen 409 and are discharged from the corn kernel discharge port, and the corn cobs are blocked by the screen 409 and are discharged from the corn cob discharge port along the inclined surface of the screen 409.

[0036] Among them, if the diameters of the first threshing roller 407 and the second threshing roller 408 are not equal at the same height, it is easy for the fruit ears to be crowded to one side, resulting in overload on one side, which in turn affects the threshing effect. Therefore, the diameters of the two rollers should be as equal as possible. In this embodiment, the diameters of the two rollers are both 168mm, and the height of the upper ridges is 10mm.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
