Wherein the separation component is used for removing the particles of the hair vetch; the screening component is used for screening and removing impurities of the particles threshed by the threshing component; the aggregate component is used for collecting particles which are screened and purified by the screening component.

In the present embodiment, the threshing assembly mainly comprises a drum 100 and a housing 102, wherein the drum 100 is rotatably arranged inside the housing 102. For example, a shaft head may be fixedly connected to each end of the drum 100, and a corresponding frame may be provided, on which two bearing seats are provided to be engaged with the shaft heads, respectively. The shaft head and the roller 100 can be matched in a welding mode, an interference fit mode and the like. The housing 102 is then fixedly supported on the frame, such as by welding or by fixedly attaching the housing 102 to the frame via a support structure. This achieves the object that the drum 100 is rotatably disposed inside the casing 102.

A first threshing device is arranged on the outer circumferential surface of the drum 100, and a second threshing device 104 matched with the first threshing device is arranged on the inner wall of the shell 102. Wherein, when the roller 100 rotates, the first threshing device can cooperate with the second threshing device 104 to remove the particles on the hair vetch.

Specifically, the first threshing device and the second threshing device 104 remove the particles of the furrows through mutual friction, shearing and other actions, that is, when the furrows are put on the roller 100, the furrows are brought into the shell 102 along with the rotation of the roller 100, and the particles of the furrows are removed through mutual friction, shearing and other actions of the first threshing device and the second threshing device 104.

For example, one U-shaped set tooth 106 may be provided, two L-shaped set teeth 108 may be provided, one U-shaped set tooth 106 may be provided, and so on. The embodiment of the present invention does not limit the specific arrangement of the U-shaped shifting teeth 106 and the L-shaped shifting teeth 108, and can be flexibly configured according to actual situations.

In this embodiment, the drum 100 may be made of a metal material, a plurality of threaded holes are formed in the outer circumferential surface of the drum 100, and threaded ends are formed at the lower ends of the U-shaped dialing tooth 106 and the L-shaped dialing tooth 108, so that the U-shaped dialing tooth 106 and the L-shaped dialing tooth 108 can be detachably connected to the outer circumferential surface of the drum 100 in a threaded connection manner.

Further, the angle between the U-shaped teeth 106 and the central axis of the drum 100 increases gradually along the feeding direction of the drum 100.

As shown in fig. 4, the included angle between the U-shaped poking teeth 106 and the central axis of the roller 100 is set to be gradually increased along the feeding direction of the roller 100, so that the travelling speed of the hair vetches can be effectively slowed down in the early stage of threshing, and the particles of the hair vetches are fully removed through the cooperation of the first threshing device and the second threshing device 104; in the later stage of threshing, the particles of the hair vetch are basically and completely removed, so that the speed of the hair vetch can be increased, and the straws of the hair vetch are quickly discharged to the outside of the shell 102.

Further, as shown in fig. 1 and 2, in order to complete the change of the travelling speed of the hair vetch inside the housing 102 by cooperating with the U-shaped poking teeth 106, the second threshing device 104 in this embodiment has an arc-shaped section which is bent towards the discharging direction of the roller 100, and the arc degree of the arc-shaped section is gradually increased along the discharging direction of the roller 100. Therefore, in the early stage of threshing, the travelling speed of the hair vetch can be well limited between the arc-shaped section on the second threshing device 104 and the U-shaped poking teeth 106, and the threshing device for the long-diameter crops has enough time to thresh the hair vetch.

Further, a first end of the drum 100 extends out of the housing 102, a second end of the drum 100 extends into the housing 102, the first end of the drum 100 has a conical convex section 110, and a spiral feeding member 112 is disposed on an outer circumferential surface of the conical convex section 110.

The first end of the drum 100 specifically refers to the left end of the drum 100 as shown in fig. 2, and the second end of the drum 100 refers to the right end of the drum 100 as shown in fig. 2. The arrangement of the first end of the roller 100 with the conical raised section 110 ensures that the brooch can be smoothly fed into the housing 102. Furthermore, the provision of the helical feed member 112 on the conical convex section 110 ensures that the brooch can be wound around the conical convex section 110 without falling off the conical convex section 110.

As mentioned above, the screening component is used for screening and removing impurities from the particles threshed by the threshing component; therefore, in order to ensure that the granules of the sweet potatoes in the shell 102 can smoothly fall into the screening assembly, the lower side plate of the shell 102 is also provided with a blanking hole. Through threshing of the threshing component, particles can fall into the screening component through the blanking hole.

The screening subassembly sets up in threshing component's below and the position that blanking hole corresponds and is arranged in filtering the impurity in the granule.

In this embodiment, the screening assembly includes a screening hopper 114, a first vibrating plate 116, a second vibrating plate 118 and a screening net 120, the first vibrating plate 116 and the second vibrating plate 118 are respectively disposed at two ends of the screening hopper 114, a top plate of the screening hopper 114 is provided with a plurality of first screening holes, the screening net 120 is disposed below the top plate and is fixedly connected with the second vibrating plate 118, the screening net 120 is provided with a plurality of second screening holes, and the aperture of the second screening holes is smaller than that of the first screening holes; a collection hopper 122 is disposed below the screen hopper 114.

Thus, the screen mesh 120 is disposed between the first vibrating plate 116 and the second vibrating plate 118, and the position of the screen mesh 120 corresponds to the position of the top plate.

In the present embodiment, the screen mesh 120 is fixedly connected to the second vibrating plate 118, for example, the two may be connected by welding or the like. A plurality of second material sieving holes are further formed in the material sieving net 120, and the aperture of each second material sieving hole is smaller than that of each first material sieving hole.

Thus, the straw of the sweet potato discharged from the roller 100 can fall into the crusher 126 from the discharge position of the roller 100, and is crushed into powder by the crusher 126, so that the powder can be applied as fertilizer to soil. Wherein the crusher 126 is also connected to the power plant.
