Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a new type of agricultural screening machine. Background Technology

[0002] In the modern agricultural production system, the refined processing of agricultural products after harvest plays a key role in enhancing product added value and meeting diversified market demands. As an important part of this process, the efficiency and quality of screening directly affect the economic benefits and market competitiveness of agricultural products. When screening granular agricultural products, a new type of agricultural screening machine is needed.

[0003] However, due to the poor anti-clogging screening capabilities of existing agricultural screening machines, it is not convenient to effectively clean the screening filter screen during actual use. Particles often clog the filter screen during screening, thus affecting the filtration efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This novel agricultural screening machine, through its unique anti-clogging screening mechanism, greatly enhances the anti-clogging capability during the screening process. When the drive motor is started, it drives the adjusting screw to rotate. Since the adjusting screw is threadedly connected to the sliding screw block, the sliding screw block will make linear reciprocating motion on the adjusting screw block along the first sliding guide groove. At the same time, the connecting slider slides smoothly on the support guide rod and moves in coordination with the sliding screw block, so that the connecting support crossbar can stably drive the stirring steel brush to reciprocate and clean above the screening filter plate, preventing particles from clogging the screening filter plate, thereby improving the screening efficiency.

[0016] 2. This new type of agricultural screening machine is movably connected to the screening filter plate via a placement groove on one side of the screening box. The screening filter plate is installed in the middle of the limiting baffle. This design makes the disassembly and installation of the screening filter plate extremely convenient. When the screening filter plate needs to be deeply cleaned or replaced, the operator can easily pull the screening filter plate out of the screening box by simply using the handle on the limiting baffle. This makes it easy to replace the filter plate with different filter sizes according to the screening needs, and facilitates screening operations for various crops. Attached Figure Description

[0023] Please see Figures 1-4 This utility model provides a technical solution: a new type of agricultural screening machine, including a screening box 1, a limiting plate 2 is movably installed on one side of the screening box 1, a screening filter plate 3 is fixedly installed on the side of the limiting plate 2 near the screening box 1, the screening filter plate 3 is located inside the screening box 1, and an anti-blocking screening mechanism 4 is provided at the top of the screening box 1.

[0024] The anti-blocking screening mechanism 4 includes a first sliding guide groove 401. A first sliding guide groove 401 is provided on one side of the top of the screening box 1. A drive motor 402 is fixedly installed on one side of the screening box 1. An adjusting screw 403 is fixedly installed on the output shaft end of the drive motor 402. The adjusting screw 403 extends movably into the interior of the first sliding guide groove 401. A supporting movable block 404 is fixedly installed on the inner wall of the first sliding guide groove 401 on the side away from the drive motor 402. The side of the adjusting screw 403 away from the drive motor 402 is rotatably connected to the side of the supporting movable block 404. A sliding screw block 405 is threadedly connected to the outer end of the adjusting screw 403. A second sliding guide groove 406 is provided on the top of the screening box 1 on the side away from the first sliding guide groove 401. A support guide rod 407 is fixedly installed inside the sliding guide groove 406. A connecting slider 408 is movably sleeved on the outer end of the support guide rod 407. A connecting support crossbar 409 is fixedly installed on the top of the sliding screw block 405 and the connecting slider 408. Two reinforcing connecting rods 410 are fixedly installed on the bottom end of the connecting support crossbar 409. An agitating steel brush 411 is fixedly installed on the bottom end of the two reinforcing connecting rods 410. When the drive motor 402 is started, the adjusting screw 403 is rotated, causing the sliding screw block 405 to reciprocate linearly on the adjusting screw 403, which drives the connecting support crossbar 409 to move. At the same time, the connecting slider 408 slides on the support guide rod 407, thereby stably driving the reinforcing connecting rod 410 and the agitating steel brush 411 to move.

[0025] A placement groove 5 is provided on one side of the screening box 1, which is movably connected to the screening filter plate 3. Limiting baffles 6 are fixedly installed on the inner walls of both sides of the screening box 1. The screening filter plate 3 is movably connected to the middle of the limiting baffles 6. A handle 7 is fixedly installed on the side of the limiting plate 2 away from the screening filter plate 3. A PLC controller 8 is fixedly installed on one side of the screening box 1. The PLC controller 8 is electrically connected to the drive motor 402. A discharge port 9 is provided on one side of the screening box 1. A guide plate 10 is fixedly installed at the bottom of the screening box 1. Several support legs 11 are evenly fixedly installed at the bottom of the screening box 1. Anti-slip pads 12 are fixedly installed at the bottom of the support legs 11. The screening filter plate 3 is placed into the limiting baffle 6 inside the screening box 1, and the limiting baffle 6 limits and stabilizes the screening filter plate 3.

[0026] Working Principle: When needed, the new agricultural screening machine is first placed stably in the required position using the support legs 11 and anti-slip pads 12. According to the screening requirements, the appropriate screening filter plate 3 is placed into the limiting baffle 6 inside the screening box 1. The limiting baffle 6 stabilizes the screening filter plate 3 and facilitates replacement and cleaning as needed. Then, the crops to be screened are placed onto the screening filter plate 3 inside the screening box 1. The crops are screened by the screening filter plate 3. Smaller particles fall onto the guide plate 10 at the bottom of the screening box 1 through the discharge port. 9. Larger particles are discharged and left on the screening filter plate 3. During screening, the drive motor 402 is started to rotate the adjusting screw 403, causing the sliding screw block 405 to move back and forth linearly on the adjusting screw 403. This drives the connecting support crossbar 409 to move, and at the same time drives the connecting slider 408 to slide on the support guide rod 407. This stabilizes the movement of the reinforcing connecting rod 410 and the stirring steel brush 411. The stirring steel brush 411 reciprocates to stir the crop particles on the screening filter plate 3, effectively preventing the crop particles from clogging the screening filter plate 3 and effectively improving the screening efficiency. After screening, the large crop particles on the screening filter plate 3 can be removed.
