Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.
[0025] Referring to Figure 1-8 , the clean grain and stone removing device includes a mounting frame 1. An electric slide rail 2 is fixedly installed at the inner top of the mounting frame 1. An electric slider 3 is slidably connected in the electric slide rail 2. A connecting rod 4 is fixedly installed at the bottom of the electric slider 3. A connecting plate 5 is fixedly installed at the bottom end of the connecting rod 4. Sliding mechanisms are provided on both side walls of the connecting plate 5. Frames 6 are fixedly installed on the side walls of both sliding mechanisms. The sliding mechanism includes two chutes 11 opened on the side wall of the connecting plate 5. Limiting rods 13 are fixedly installed in both chutes 11. A slider 12 is slidably connected on the limiting rods 13. First springs 14 are fixedly connected between the opposite inner side walls of the two ends of the slider 12 and the chutes 11. The frame 6 is fixedly installed between the side walls of the two sliders 12;
[0026] Both side walls at the two ends of the frame body 6 are fixedly installed with side baffles 9. A connecting mechanism is arranged between the two side baffles 9. The connecting mechanism includes a guide plate 10 which is fixedly installed between the side walls of the two side baffles 9 and is inclined. Through the arrangement of the guide plate 10, it can guide the screened rice, so that the rice can smoothly fall into the collection basin for collection. A limiting plate 15 is fixedly installed at the bottom of the guide plate 10. The opening at one end of the limiting plate 15 is larger than the rotation diameter of the driving rod 17. Therefore, no matter where the driving rod 17 is, the opening on the limiting plate 15 can enable the driving rod 17 to slide into it;
[0027] A clamping plate 20 is fixedly installed at the bottom of the frame body 6. A resisting plate 24 is fixedly installed between the two side baffles 9. A screen plate 19 is placed between the clamping plate 20 and the resisting plate 24. The screen plate 19 is clamped with the two side baffles 9. A fixing mechanism is arranged on the side wall of the frame body 6. The fixing mechanism penetrates through the screen plate 19 and the resisting plate 24 and is slidably connected with them. The fixing mechanism includes a limiting plate 21 fixedly installed on the side wall of the frame body 6. A clamping member 22 is slidably connected through the limiting plate 21. A plurality of second springs 23 are fixedly connected between the top of the clamping member 22 and the limiting plate 21. The bottom end of the clamping member 22 penetrates through the screen plate 19 and the resisting plate 24 and is slidably connected with them. Through the arrangements of the side baffle 9, the clamping plate 20, the resisting plate 24 and the fixing mechanism, the fixed screen plate 19 can be quickly disassembled, which is convenient for the operator to clean the stones blocked on the screen plate 19;
[0028] A fixing frame 7 is fixedly installed on the side wall of the mounting frame 1. A feed hopper 8 is fixedly installed at the end of the fixing frame 7. A driving mechanism is arranged at the top of the bottom end of the mounting frame 1. The driving mechanism extends into the connecting mechanism and is slidably connected with it. The driving mechanism includes a driving motor 18 fixedly installed on the top of the bottom end of the mounting frame 1. A disc 16 is fixedly installed at the end of the output shaft of the driving motor 18. A driving rod 17 is fixedly installed on the top of the disc 16. The driving rod 17 extends into one of the limiting plates 15 and is slidably connected with it. Through the arrangements of the electric slide rail 2, the electric slider 3, the connecting rod 4, the connecting plate 5, the frame body 6, the sliding mechanism, the connecting mechanism and the driving mechanism, when cleaning the stones blocked on the screen plate 19, it can ensure the normal progress of the screening work and ensure the screening efficiency.
[0029] The functional principle of the present utility model can be elaborated through the following operation methods:
[0030] When it is necessary to perform stone removal on paddy, first, the operator places two collection basins on the mounting frame 1, starts the drive motor 18, and the drive motor 18 drives the disc 16 to rotate. When the disc 16 rotates, it drives the driving rod 17 to rotate. When the driving rod 17 rotates, it drives the guide plate 10 to vibrate back and forth through the extrusion limiting plate 15. The guide plate 10 drives the screen plate 19 on the left frame 6 to vibrate back and forth through the side baffle 9. Then the operator pours the paddy into the feed hopper 8, and the paddy falls onto the left screen plate 19 under the action of gravity. The vibrating screen plate 19 screens the paddy, and the paddy passes through the screen plate 19 and falls onto the guide plate 10, and finally falls into the left collection basin under the guiding action of the guide plate 10. When it is necessary to clean the stones blocked on the left screen plate 19, the operator turns off the drive motor 18 to stop the rotation of the left frame 6. Then the operator starts the electric slide rail 2, and the electric slide rail 2 drives the electric slider 3 to move leftward. The electric slider 3 drives the frame 6 on the connecting plate 5 to move leftward through the connecting rod 4, so that the screen plate 19 on the right frame 6 slides to directly below the feed hopper 8. When the limiting plate 15 on the right guide plate 10 moves leftward, the opening on the right limiting plate 15 limits the driving rod 17 on the disc 16, so that the driving rod 17 on the disc 16 finally slides into the right limiting plate 15. Then the operator starts the drive motor 18 to continue the screening operation. At this time, the operator pulls up the left clamping part 22 upward, so that the bottom end of the clamping part 22 is separated from the screen plate 19 and the abutting plate 24. Then the operator can take out the screen plate 19 between the clamping plate 20 and the abutting plate 24 to clean the stones blocked on its top.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
