[0047] In this embodiment, the lifting mechanism includes a No. 1 rotating shaft 40 fixedly connected to the output shaft of the No. 1 motor 3, a No. 2 rotating shaft 41 is rotatably connected to the lifting frame 2, one end of the No. 1 rotating shaft 40 and the No. 2 rotating shaft 41 are respectively fixedly connected to a driving gear 42 and a driven gear 43, the driving gear 42 and the driven gear 43 are meshed, a No. 3 rotating shaft 44 is rotatably connected to the lifting frame 2, both ends of the No. 2 rotating shaft 41 and both ends of the No. 3 rotating shaft 44 are fixedly connected to lifting wheels 45, and the four lifting wheels 45 are respectively connected to two transmissions.

[0050] The implementation principle of a rice lifting device for rice production and processing in the embodiment of the present application is as follows: first, the device is moved to a specified position, and the rice is poured into the lifting box 8, and the rice falls on the primary filter plate 21. The second motor 9 is started by the control 57, so that the output shaft of the second motor 9 drives the driving shaft 11 to rotate, and the driving shaft 11 drives the first bevel gear 12 fixedly connected to rotate. Due to the meshing between the first bevel gear 12 and the second bevel gear 14, the first bevel gear 12 drives the vertical rotating rod 13 to rotate through the second bevel gear 14, and the vertical rotating rod 13 drives the two sleeves 15 to rotate. The two sleeves 15 drive the two fixedly connected rubber plates 16 to rotate, and the materials on the primary filter plate 21 and the secondary filter plate 22 are moved, so as to avoid material piling. The accumulation makes the primary filter plate 21 and the secondary filter plate 22 blocked. At the same time, the vertical rotating rod 13 drives the worm wheel 25 to rotate through the fixedly connected worm 23, and the worm wheel 25 drives the fixedly connected horizontal rotating rod 24 to rotate. The horizontal rotating rod 24 drives the two cams 26 to rotate and reciprocate to squeeze the two reset plates 19 that are in contact with the two cams 26 to move downward. When the two reset plates 19 move downward, the two reset springs 18 are compressed. When the two reset springs 18 release their elastic force, the two reset plates 19 can be driven to reset, so that the two reset plates 19 can reciprocate vertically. The two reset plates 19 drive the two fixedly connected support plates 20 to move reciprocatingly. The two support plates 20 drive the primary filter plate 21 and the secondary filter plate 22 to move up and down, and utilize the two reciprocating The elastic force of the position spring 18 produces vibration, so that the primary filter plate 21 filters the excessive impurities in the rice, and the filtered rice falls on the secondary filter plate 22. The secondary filter plate 22 can filter the dust and smaller impurities in the rice, thereby achieving multi-stage filtration and improving the filtration effect. At the same time, when the driving shaft 11 rotates, it can drive the fixedly connected gear 1 27 to rotate. Due to the meshing between the gear 1 27 and the gear 2 30, the gear 1 27 drives the rotating rod 29 to rotate through the gear 2 30, and the rotating rod 29 drives the fixedly connected fan blade 31 to rotate, generating suction, and the dust and lighter impurities floating in the lifting box 8 are sucked into the three-way pipe 34 through the three-way pipe 34, and then transported to the dust collection box 28 through the dust collecting hood 33, and the dust blocking plate 32 can block dust and impurities to avoid damage to the fan blades 31, thereby achieving the effect of collecting dust and impurities. When it is necessary to deal with impurities and dust, due to the discharge pipe provided at the bottom of the dust box 28, the impurities and dust can be discharged and processed through the discharge pipe. The rice filtered from the secondary filter plate 22 falls on the guide plate 1 35 and the guide plate 2 36, and slides to the feed hopper 37 to enter the conveying box 10. The box door 58 is opened, and the driving shaft 11 drives the fixedly connected conveying auger 39 to rotate and transport the rice. When it is necessary to lift the lifting box 8, the controller 57 is used to start the No. 1 motor 3, so that the output shaft of the No. 1 motor 3 drives the No. 1 rotating shaft 40 to rotate. Due to the meshing between the driving gear 42 and the driven gear 43,The first rotating shaft 40 drives the passive gear 43 to rotate through the active gear 42, and the passive gear 43 drives the second rotating shaft 41 to rotate. Since there are two transmission belts 46 between the four lifting wheels 45, the two transmission belts 46 drive the two fixedly connected connecting blocks 47 to move upward, and the two connecting blocks 47 drive the fixedly connected limit frame 5 to move upward, and the limit frame 5 drives the two plug boards 7 to move upward through the two fixedly connected mounting seats 6, and the two plug boards 7 drive the lifting box 8 upward, thereby achieving the lifting effect. The whole device is connected to a power supply and a general control button, which is controlled by the general control button. Since the equipment matched with the control button is a common equipment and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be repeated here.

[0051] Embodiment 2

[0052] The difference between this embodiment and the first embodiment is that a fixing screw 48 is rotatably connected between the two mounting seats 6, and two adjusting plates 49 are symmetrically threadedly connected to the fixing screw 48. A fixing column 50 is fixedly provided on one side of the two adjusting plates 49. One end of the two fixing columns 50 is respectively located in the two mounting seats 6 and the two plugging plates 7. A turntable 51 is fixedly connected to one end of the fixing screw 48. A crank 52 is fixedly provided at an eccentric position on one side of the turntable 51. When the two plugging plates 7 are located in the two mounting seats 6, the user shakes the crank 52 by hand and drives the turntable 51 to rotate, and the turntable 51 drives the fixing screw 48 to rotate. Since the thread directions at both ends of the fixing screw 48 are opposite to the thread directions of the two adjusting plates 49, the two adjusting plates 49 move away from each other, and the two adjusting plates 49 drive the two fixing columns 50 to move away from each other, and insert the two mounting seats 6 to limit and fix the two plugging plates 7, thereby achieving the installation effect. All structures in the present application can be selected in terms of material and length according to actual usage. The accompanying drawings are all schematic structural drawings, and the specific actual dimensions can be appropriately adjusted.
