[0026] The first driving motor 401 is installed on the fixed support base 20, and in the driving process of the up-down swinging mechanism 40, the first driving motor 401 is in a static state. The rotating shaft of the first driving motor 401 drives the first cam 402 to rotate, the first cam 402 drives the first connecting rod 403 to move, and the first connecting rod 403 drives the tray 701 on the sorting mechanism 70 to swing up and down.

[0027] The front-back swinging mechanism 50 of the utility model drives the tray 701 on the sorting mechanism 70 to swing front and back.

[0028] Specifically, in a preferred embodiment, the front-back swinging mechanism 50 comprises a second driving motor 501, a second cam 502 and a second connecting rod 503, the body of the second driving motor 501 is fixedly connected with the movable support frame, the rotating shaft of the second driving motor 501 is fixedly connected with one end of the second cam 502, the other end of the second cam 502 is hingedly connected with one end of the second connecting rod 503, and the other end of the second connecting rod 503 is hingedly connected with the sorting mechanism 70, so as to drive the sorting mechanism to swing front and back.

[0029] The second driving motor 501 is installed on the left side or the right side of the movable support frame 30, and in the driving process of the front-back swinging mechanism 50, the second driving motor 501 moves synchronously with the movable support frame 30, the rotating shaft of the second driving motor 501 drives the second connecting rod 503 to move, and the second connecting rod 503 drives the tray 701 to swing front and back.

[0032] The third driving motor 601 is installed at the rear end of the movable support frame 30. The rotating shaft of the third driving motor 601 is downwardly arranged, and the rotating shaft of the third driving motor 601 drives the third cam 602 to rotate in the horizontal direction in the rotating process. The third cam 602 drives the third connecting rod 603 to move in the rotating process, and the connecting rod moves in the oblong hole 6041 in the front and back directions, which does not affect the movement of the left and right translation plate 604. The movement of the connecting rod in the left and right directions, with the assistance of the sliding block 605 and the guide rail 606, moves the left and right translation plate left and right, and further moves the tray 701 left and right.

[0033] In a preferred embodiment, the sorting mechanism 70 comprises a tray 701, a vertical connecting rod 702, an upper cross rod 703, a fixed plate 704, a middle cross rod 705, and an L-shaped plate 706, the left side and the right side of the tray 701 are respectively sleevedly connected with the lower ends of the vertical connecting rods 702, the upper ends of the vertical connecting rods 702 are connected with one end of the upper cross rod 703, the upper cross rod 703 is provided with a universal joint 80, so that the vertical connecting rod 702 can swing 360 degrees in the horizontal direction, the other end of the upper cross rod 703 is fixedly connected with the upper end of the fixed plate 704, the lower end of the fixed plate 704 is fixedly connected with the movable support frame 30, the middle end of the vertical connecting rod 702 is further sleevedly connected with one end of the middle cross rod 705, the other end of the middle cross rod 705 is connected with the L-shaped plate 706, and the middle end of the L-shaped plate 706 is connected with the left and right translation plate 604 through bolts.

[0034] The front and back movement and the left and right movement of the material tray 701 will drive the vertical connecting rod 702 to move, and in a preferred embodiment, a universal joint 80 is arranged at the sleeving position of the middle cross rod 705 and the vertical connecting rod 702, when the front and back movement of the material tray 701 drives the front and back movement of the vertical connecting rod 702, the middle cross rod 705 will not move due to the limited swing range under the action of the universal joint 80, so that the left and right translation plate 604 will not move forward and backward. At the same time, the material tray 701 and the second connecting rod 503 are connected through a short shaft, and a universal joint 80 is arranged at the connecting position of the second connecting rod 503. When the material tray 701 moves left and right, the second connecting rod 503 will not move left and right due to the limited swing range under the action of the universal joint 80. In this way, the movement of the front and back driving mechanism and the left and right driving mechanism is relatively independent, that is, the movement of the front and back driving mechanism and the left and right driving mechanism does not affect each other. At the same time, it can also work cooperatively, so that the material tray 701 can move forward, backward, left and right at the same time.

[0035] Some rice seeds are easy to roll, for example, round rice, in this case, the material tray 701 with a relatively rough bottom surface or a certain blocking effect can be appropriately selected to make the sorting effect better.

[0036] The fan 90 of the utility model can rotate at an angle, and the height can also be adjusted. The adjustment of the angle and the height is relatively common, and will not be described in detail.

[0037] It should be noted that in order to ensure the smoothness and durability of the hinge, a bearing is arranged at the rotating shaft. Since the shaft and the bearing are commonly used, they will not be described in detail.

[0038] Generally, the material tray 701 has a baffle around the periphery to prevent the rice seeds from spilling out during the swinging process. Of course, in actual use, the hopper is inclined upward at a certain angle, so that the front end of the hopper can also be without a baffle. In this way, the poor rice seeds can be easily scooped out by hand. In order to facilitate the pouring of the selected rice seeds, the side baffle can also be designed as a detachable baffle, such as a plug. In this way, the rice seeds can be poured out by gravity or appropriate swinging, vibration, etc.

[0039] The material tray of the application can be made by traditional manual methods, such as weaving with rattan, bamboo strips, grass ropes, etc. It can also be formed by modern extrusion, casting, etc. with rubber, metal, etc. The friction on the surface of the material tray can be generated by the concave-convex structure after weaving and the properties of the material itself, such as the concave-convex structure formed by rattan weaving and the rough properties of rattan itself. The friction on the surface of the material tray can also be generated by the grooves and protrusions produced in the process of mechanical processing, such as the rubber material tray. The surface of the material tray can be processed to have a certain friction by carving concave-convex corrugations on the rubber surface and adding the rough properties of the material itself, so that the surface has a certain friction.

[0040] The above disclosed is only the preferred embodiment of the present application, of course, cannot be limited by this to limit the scope of the present application, the person skilled in the art can understand that all or part of the processes of the above-mentioned embodiments are realized, and the equivalent changes made according to the present application claims still belong to the scope covered by the present application.
