[0002] Rice, as the staple food for people in most parts of China, plays an important nutritional and economic role. In the process of rice production and processing, how to improve the quality of rice, enhance production efficiency, and ensure the cleanliness of the production environment has always been an issue widely concerned in the industry. To meet this demand, various lifting devices have emerged, aiming to optimize the rice processing process, especially in the lifting and transportation processes, to ensure the cleanliness and quality of rice. As an important equipment for rice production and processing, the lifting device plays a crucial role. Existing lifting devices are mostly used to lift rice from one processing step to the next. In this process, a series of problems are often encountered, including the carrying of impurities in the rice and the flying of dust. These factors not only affect the quality of rice but also may affect the hygiene of the working environment. Therefore, how to effectively clean the rice, filter out impurities, and ensure the continuous operation of the equipment has become the core issue in the design of the lifting device.

The invention has a simple structure. Before lifting and transporting rice, impurities and dust in the rice can be filtered through a multi-stage filtering mechanism, and at the same time, the generated dust can be collected, improving the filtering effect, avoiding the situation of affecting the quality of rice, and being convenient for people to use.

Then, the rice to be processed is poured above the first mounting plate 8, and then the driving component is started.

[0044] The lifting component includes a frame 2, a hydraulic cylinder 3 is fixed in the middle of the frame 2, the top end of the telescopic rod of the hydraulic cylinder 3 is fixed with a connecting frame 4, and the lifting box 5 is fixedly connected with the connecting frame 4; during operation, the telescopic rod of the hydraulic cylinder 3 is controlled to extend so as to lift the lifting box 5 as required, and realize lifting the rice to a specified height.

[0045] A second mounting plate 16 is arranged below the first mounting plate 8, the second mounting plate 16 is fixedly connected with the movable rod 14, two baffle plates 17 are symmetrically and obliquely arranged on both sides of the second mounting plate 16, and two support rods 23 are fixedly arranged side by side inside the box body and below the baffle plates 17. Sliders one 24 are symmetrically and rotatably mounted at both bottom ends of the baffle plates 17, the sliders one 24 are slidably sleeved on the support rods 23, sliders two 26 are respectively rotatably mounted at both top ends of the baffle plates 17, and the sliders two 26 are slidably arranged in limit grooves formed at both bottom ends of the two ends of the second mounting plate 16. A second spring 27 is arranged between the two sliders two 26 on both sides;

[0046] During operation, by obliquely arranging the baffle plates 17 below the filter plate 7, the rice passing through the filter plate 7 freely falls onto the baffle plates 17 and collides with the baffle plates 17, which can further separate dust and fine impurities, so that the dust and fine impurities fly up, facilitating subsequent absorption of impurities through negative pressure pumping; when the movable plate 22 moves up and down, it synchronously drives the second mounting plate 16 to move up and down, and then drives the baffle plates 17 on both sides to move. The bottom of the baffle plates 17 drives the sliders one 24 to reciprocate along the support rods 23, and the top of the baffle plates 17 drives the sliders two 26 to slide along the limit chute 31 arranged on the second mounting plate 16, realizing the up and down reciprocating jitter of the baffle plates 17, so as to shake off the rice on the surface of the baffle plates 17, enabling the rice to smoothly move to the bottom of the lifting box 5.

[0047] A support frame 28 is fixedly arranged obliquely inside the dust collection box 6, the filter screen 20 is installed on the top of the support frame 28, a vertical cylinder 29 is fixed below the support frame 28, a positioning rod 35 is fixed at the bottom of the filter screen 20, and the positioning rod 35 is hermetically and slidably inserted into the vertical cylinder 29; during operation, through the cooperation of the positioning rod 35 and the vertical cylinder 29, it is convenient for the installation and disassembly of the filter screen 20.

[0048] A sliding cavity 34 is formed in the middle of the end of the support rod 23. A piston 33 is hermetically and slidably installed in the middle of the sliding cavity 34. A pushing block 32 is fixed to the side of the first slider 24. A sliding groove 31 is formed below the end of the support rod 23. The top of the pushing block 32 is slidably inserted into the sliding groove 31. The pushing block 32 is fixedly connected to the piston 33 through a connecting rod. The sliding cavity 34 is communicated with the vertical cylinder 29 through a connecting pipe 30. During operation, the first slider 24 reciprocates along the support rod 23 synchronously with the up-and-down movement of the material baffle 17. When the first slider 24 approaches the vertical cylinder 29, the piston 33 is pushed to move by the pushing block 32, and the air inside the sliding cavity 34 is squeezed into the vertical cylinder 29 through the connecting pipe 30, pushing the positioning rod 35 and the filter screen 20 to move upward. When the first slider 24 moves away from the vertical cylinder 29, the pushing block 32 and the piston 33 are driven to move in the reverse direction, so that the air inside the vertical cylinder 29 is sucked into the sliding cavity 34. At this time, the positioning rod 35 and the filter screen 20 are driven to move downward, causing the filter screen 20 and the support frame 28 to collide, thereby vibrating the filter screen 20, so that the dust and impurities on the surface of the filter screen 20 are vibrated up and move downward along the inclined filter screen 20. This can prevent dust and impurities from accumulating on the surface of the filter screen 20, resulting in blockage of the filter screen 20, so as to keep the filter screen 20 in good dust filtering effect.

[0049] An inverted convex-shaped movable cavity is formed in the middle of the inner wall of the top of the through groove 21. A T-shaped movable plate 22 is slidably installed in the middle of the movable cavity. A third spring 36 is installed on the top of the movable plate 22. During operation, the movable plate 22 is pushed to move downward by the third spring 36. When the filter plate 7 is in a horizontal position, the bottom end of the movable plate 22 is always in contact with the filter plate 7. In this way, during the up-and-down movement of the filter plate 7, the rice above the filter plate 7 is blocked from leaking out of the through groove 21. The convex-shaped movable cavity can limit the descending distance of the movable plate 22. When the filter plate 7 rotates downward and tilts, the bottom end of the movable plate 22 is not in contact with the filter plate 7. At this time, the impurities on the filter plate 7 can flow out of the through groove 21 along the inclined plane.

[0050] Embodiment 2: As Figure 2 shown, compared with Embodiment 1, another implementation manner of the present invention is: a discharge port is formed in the bottom side wall of the lifting box 5, the discharge port corresponds to the conveying auger 10, and a sealing plate 11 is detachably installed outside the discharge port. During operation, when discharging is required, the sealing plate 11 is opened, and at this time, the rice at the bottom of the lifting box 5 can be pushed out through the conveying auger 10 to achieve automatic discharging.

[0051] Working principle: Electrify the electromagnet 25, the electromagnet 25 generates magnetic force, and the electromagnet 25 adsorbs with the iron block on the filter plate 7, so that the two filter plates 7 are in a horizontal position and tightly fit under the first mounting plate 8. Then pour the rice to be processed above the first mounting plate 8, and then start the driving assembly. Control the first mounting plate 8 and the filter plate 7 to move up and down reciprocally through the driving assembly, so as to make the filter plate 7 vibrate. The rice freely falls to the bottom of the lifting box 5 through the sieve holes of the filter plate 7, and the larger granular impurities in the rice are retained at the top of the filter plate 7, realizing the screening of the rice; Lift the lifting bucket through the lifting assembly, so as to achieve the lifting effect, so as to transfer the rice to the designated position as required; Push out the rice at the bottom of the lifting box 5 through the conveying auger 10 to realize automatic discharging;

[0052] Drive the first drive shaft 9 and the conveying auger 10 to rotate through the motor to realize automatic discharging, and drive the second drive shaft 12 to rotate synchronously through the cooperation of the transmission wheels and transmission belts, and then drive the cam 13 to rotate. Use the cam 13 to push the movable rod 14 to move up and down reciprocally, and then drive the first mounting plate 8 and the filter plate 7 to move up and down reciprocally, so as to shake and screen the rice;

[0053] During the rice screening process, dust and fine impurities will float in the lifting box 5. While the second drive shaft 12 rotates, it drives the vertical rod 18 and the fan 19 to rotate through the helical gear set. Continuously exhaust the air inside the dust collection box 6 through the fan 19, so as to generate negative pressure inside the dust collection box 6, and then the dust and fine impurities floating in the lifting box 5 can be sucked into the dust collection box 6 through the through groove 21, avoiding the influence of dust and fine impurities on the quality of the rice; In addition, a filter screen 20 is provided to block dust and impurities, so as to protect the fan 19 and prevent the fan 19 from being damaged; By setting a detachable side plate, it is convenient to clean the filter screen 20 and the inner wall of the dust collection box 6;

[0054] The first slider 24 moves up and down along the support rod 23 synchronously with the baffle 17. When the first slider 24 approaches the vertical cylinder 29, the piston 33 is pushed to move through the push block 32, and the air inside the sliding cavity 34 is squeezed into the vertical cylinder 29 through the connecting pipe 30, pushing the positioning rod 35 and the filter screen 20 to move upward. When the first slider 24 moves away from the vertical cylinder 29, drive the push block 32 and the piston 33 to move in the reverse direction, thereby sucking the air inside the vertical cylinder 29 into the sliding cavity 34. At this time, drive the positioning rod 35 and the filter screen 20 to move downward, so that the filter screen 20 and the support frame 28 collide, and then the filter screen 20 vibrates, so that the dust and impurities on the surface of the filter screen 20 are shaken up and move downward along the inclined filter screen 20. This can avoid the accumulation of dust and impurities on the surface of the filter screen 20, resulting in the blockage of the filter screen 20, so as to keep the filter screen 20 in good dust filtering effect.
