[0017] In one embodiment of the present invention, a channel should be opened on the side or top of the threshing barrel 1 during actual use to facilitate the addition of oats into the threshing barrel 1. At the same time, a collecting box should be arranged on the side of the screen box 15 to collect the sieved oats.

[0018] like Figure 1 and Figure 2 As shown, as a preferred embodiment of the present invention, the threshing mechanism 100 includes a movable frame 3, a driving shaft 1 4, a driving shaft 2 5, a crushing blade 6 and a crushing roller 7; The movable frame 3 is fixedly mounted at the end of the longitudinal rotating shaft 2, and a driving shaft 1 4 and a driving shaft 2 5 are rotatably mounted on the movable frame 3; Among them, a crushing blade 6 is fixedly installed on the driving shaft 1 4, and a crushing roller 7 is fixedly installed on the driving shaft 2 5. The crushing blade 6 and the crushing roller 7 move in a circular motion synchronously with the movable frame 3; The threshing mechanism 100 also includes a spherical protrusion 1 8 and a spherical protrusion 2 9. The spherical protrusion 1 8 is evenly arranged on the outside of the crushing roller 7, and the spherical protrusion 2 9 is evenly arranged on the inside of the threshing barrel 1. The spherical protrusion 1 8 and the spherical protrusion 2 9 cooperate to improve the threshing effect.

[0019] In one embodiment of the present invention, when the longitudinal rotating shaft 2 is rotated under force, the movable frame 3 rotates synchronously. On the one hand, the driving shaft 1 4 and the crushing blade 6 move in a circle with the movable frame 3. On the other hand, the movable frame 3 also drives the driving shaft 2 5 and the crushing roller 7 to rotate synchronously to thresh the oats in the threshing barrel 1.

[0020] like Figure 1 and Figure 2As shown, as another preferred embodiment of the present invention, the gear driving mechanism 200 includes an inner gear ring 10, a driving gear 11, a connecting gear shaft 12 and a driven gear 13; The inner gear ring 10 is fixedly mounted on the end of the threshing barrel 1; The end of the driving shaft 2 5 is fixedly connected with a driving gear 11, and the end of the driving shaft 1 4 is fixedly installed with a driven gear 13; A plurality of connecting gear shafts 12 are arranged between the driving gear 11 and the driven gear 13 . The connecting gear shafts 12 are rotatably mounted on the movable frame 3 , and adjacent driving gears 11 , connecting gear shafts 12 and driven gears 13 are in meshing state.

[0021] In one embodiment of the present invention, when the movable frame 3 makes a circular motion, the driving gear 11 moves synchronously therewith. Since the driving gear 11 is meshed with the inner side of the inner gear ring 10, the driving gear 11 and the driving shaft 2 5 can rotate along the end of the movable frame 3. At the same time, multiple connecting gear shafts 12 are driven in turn to rotate along the movable frame 3, and finally the driving shaft 1 4 and the crushing blade 6 are driven to rotate.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, as another preferred embodiment of the present invention, the screening mechanism 300 includes a material drop hole 14, a screen box 15, a screen plate 16, a screen hole 17, a side door 18 and a handle 19; The drop hole 14 is arranged at the bottom of the threshing barrel 1, and a screen box 15 is arranged obliquely at the position of the drop hole 14 on the outside of the threshing barrel 1, and a plurality of screen plates 16 are arranged on the inside of the screen box 15. The screen box 15 and the screen plates 16 are correspondingly provided with evenly distributed screen holes 17, and the aperture of the screen holes 17 gradually decreases from top to bottom; A side door 18 is hingedly connected to the side of the screen box 15 at a position corresponding to the screen plate 16 , and a handle 19 is fixedly connected to the outer surface of the side door 18 .

[0023] In one embodiment of the present invention, the threshed oats pass through the drop hole 14 into the screen box 15, and sequentially pass through the sieve holes 17 provided on the plurality of sieve plates 16, thereby sieving the oats according to the size of the particles, and the sifted oats stay on the corresponding sieve plates 16.

[0024] like Figure 1 , Figure 4 and Figure 5 As shown, as another preferred embodiment of the present invention, the elastic acceleration mechanism 400 includes a driven shaft 20, a support 21, a pulley 22, a synchronous belt 23, an incomplete gear 24 and an internal tooth groove 25; The driven shaft 20 is arranged at the bottom end of the screen box 15, and the driven shaft 20 is rotatably connected to a support 21 installed on the side of the threshing barrel 1. A pulley 22 is installed on the longitudinal rotating shaft 2 and the driven shaft 20 at the same horizontal plane, and adjacent pulleys 22 are connected by a synchronous belt 23. An incomplete gear 24 is installed at the end of the driven shaft 20 , and the incomplete gear 24 is meshed with an internal tooth groove 25 provided at the bottom end of the screen box 15 .

[0025] In one example of the present invention, when the longitudinal rotating shaft 2 rotates, the pulley 22 at the corresponding position rotates synchronously, and the synchronous belt 23 is used to drive the pulley 22 at the bottom and the driven shaft 20 to rotate along the support 21. The driven shaft 20 drives the incomplete gear 24 installed at the end to rotate. Since the incomplete gear 24 is in a meshing state with the internal tooth groove 25, the screen box 15 can be pushed to slide along the threshing barrel 1.

[0026] like Figure 1 As shown, as another preferred embodiment of the present invention, the elastic acceleration mechanism 400 further includes a guide column 26, an elastic support member 27 and an arc plate 28; The guide posts 26 are symmetrically mounted on both sides of the threshing barrel 1, and the guide posts 26 are slidably connected to the screen box 15; The guide column 26 is sleeved with an elastic support member 27, one end of which is connected to the screen box 15; Arc plates 28 are also installed on both sides of the screen box 15. The arc plates 28 cooperate with each other during the movement of the screen box 15 to cover the drop holes 14 in the screening mechanism 300, thereby preventing the oats from leaking out after the screen box 15 passes over the drop holes 14 area.

[0027] In one example of the present invention, when the screen box 15 is subjected to force, it slides along the guide column 26. In this state, the elastic support member 27 is subjected to force and elastically deforms. When the screen box 15 moves to the farthest position, the elastic support member 27 is at the limit of compression. At this time, the smooth portion on the incomplete gear 24 contacts the inner tooth groove 25, and the elastic support member 27 returns to its original state, pushing the screen box 15 and the arc plate 28 to slide in the opposite direction along the threshing barrel 1.

[0028] In summary, oats are added into the threshing barrel 1 along the channel, and the external motor drives the longitudinal rotating shaft 2 to rotate. When the longitudinal rotating shaft 2 is rotated under force, the movable frame 3 rotates synchronously. On the one hand, the driving shaft 1 4 and the crushing blades 6 move in a circle with the movable frame 3. On the other hand, the movable frame 3 also drives the driving shaft 2 5 and the crushing roller 7 to rotate synchronously to thresh the oats in the threshing barrel 1. The spherical protrusion 1 8 and the spherical protrusion 2 9 cooperate to improve the threshing effect. At the same time, since the driving gear 11 is meshed with the inner side of the inner gear ring 10, the driving gear 11 and the driving shaft 2 5 can rotate along the end of the movable frame 3. At the same time, the multiple connecting gear shafts 12 are driven to rotate along the movable frame 3 in turn, and finally the driving shaft 1 4 and the crushing blades 6 are driven to rotate. The threshed oats pass through the drop hole 14 into the screen box 15, and pass through multiple screen plates in turn. The sieve holes 17 are arranged on 16, so as to screen the oats according to the size of the particles. The screened oats stay on the corresponding sieve plate 16. When the longitudinal rotating shaft 2 rotates, the pulley 22 at the corresponding position rotates synchronously, and the synchronous belt 23 is used to drive the bottom pulley 22 and the driven shaft 20 to rotate along the support 21. The driven shaft 20 drives the incomplete gear 24 installed at the end to rotate. Since the incomplete gear 24 is in a meshing state with the internal tooth groove 25, the screen box 15 can be pushed to slide back and forth along the threshing barrel 1 to accelerate the screening process. The present application can increase the contact area during use, thereby improving the threshing efficiency and avoiding the accumulation of oats in one place. At the same time, the oats are graded and screened according to the particle size, and the working process is accelerated during the screening process, thereby improving the screening effect and effectively avoiding the leakage of oats during screening.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
