Description

Technical Field

[0001] This utility model relates to the field of screening technology, specifically to an organic fertilizer ingredient screening device with replaceable sieve plates. Background Technology

[0002] With the advancement of the concept of green agricultural development, the application of organic fertilizer in agricultural production has been increasing year by year due to its ability to improve soil structure and enhance crop quality. In the process of organic fertilizer production, if the particle size of the ingredients is too coarse, it can easily lead to uneven fertilization and slow nutrient release; if the particle size is too fine, it can easily clump and clog the fertilization equipment. Therefore, it is necessary to grade the organic fertilizer ingredients through screening equipment to ensure that the final product meets the fertilization needs of different crops.

[0003] In the prior art, for example, Chinese Patent Publication No. CN222956903U discloses a fertilizer screening machine. It includes a shell and support legs at the bottom of the shell. An elastic screen with an arc-shaped structure is installed inside the shell cavity, with the center of the screen bulging upwards. A sliding groove is formed on the inner wall of the shell, and a slider adapted to the sliding groove is provided on the side wall of the elastic screen. A hydraulic rod is fixedly installed at the bottom of the elastic screen. First discharge ports are located on the left and right sides of the shell, and a second discharge port is located at the bottom of the shell. This facilitates cleaning of the screen holes and ensures screening efficiency.

[0004] Although the above technical solution has the above technical advantages, its disadvantage is that when it is necessary to change the elastic screen according to the different particle size requirements of organic fertilizer ingredients, the screening machine cannot quickly change the screen plate, which makes it unable to adapt to different screening needs and has poor flexibility. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an organic fertilizer ingredient screening device with replaceable sieve plates, solving the problem of not being able to replace sieve plates to adapt to different screening needs.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an organic fertilizer batching and screening device with replaceable sieve plates, including a screening box, a feed hopper fixedly connected to the top of the screening box, a maintenance cover plate rotatably connected to the top of the screening box, and further including: a screening component, the outer side of the screening component being fixedly connected to the inner side of the screening box, a drive motor being fixedly connected to the outer side of the screening box, a crankshaft being fixedly connected to the output end of the drive motor, a connecting rod being rotatably connected to the outer side of the crankshaft, and the end of the connecting rod away from the crankshaft being rotatably connected to the outer side of the screening component; The screening assembly includes a sliding frame with a limiting slider slidably connected to its bottom. A screening plate is inserted into the inner side of the sliding frame. A sliding block is slidably connected to the inner wall of the sliding frame via a groove, which is formed in the wall of the sliding frame. An insert rod is fixedly connected to the outer side of the sliding block. A compression spring is fixedly connected to the side of the sliding block away from the insert rod. A limiting block is fixedly connected to the top of the sliding block by bolts. The limiting slider can limit and guide the sliding frame. The screening plate reciprocates synchronously with the sliding frame, and the organic fertilizer ingredients are graded and screened through the sieve holes of the screening plate.

[0007] Preferably, the two sides of the crankshaft are rotatably connected to the inner side of the screening box, and the end of the connecting rod away from the crankshaft is rotatably connected to the outer side of the sliding frame. When the drive motor is started, its output end drives the crankshaft to rotate. When the crankshaft rotates, it can drive the sliding frame in the screening assembly to perform reciprocating linear motion through the connecting rod.

[0008] Preferably, the side wall of the limiting slider is fixedly connected to the inner wall of the screening box, and the outer side of the insertion rod is inserted into the inner wall of the screening plate through the insertion hole, and the insertion hole is opened in the side wall of the screening plate. At the same time, the two sliding blocks are pinched, forcing the compression spring to be compressed. At this time, the insertion rod can move together with the sliding block and disengage from the insertion hole.

[0009] Preferably, the screening box is rotatably connected to both sides of the transmission rollers, and a conveyor belt is sleeved on the outside of the transmission rollers. The conveyor belt is located at the bottom of the screening plate. The transmission rollers and the crankshaft are driven by a pulley set. When the crankshaft rotates, it drives the transmission rollers to rotate synchronously, thereby driving the conveyor belt sleeved on the outside of the transmission rollers to run. The conveyor belt can receive qualified materials falling from the screening plate.

[0010] Preferably, the inner side of the conveyor belt is provided with idler rollers, and the two ends of the idler rollers are rotatably connected to the inner side of the screening box. The idler rollers support the conveyor belt, prevent the conveyor belt from deforming due to the weight of the material, and ensure the stability of the conveying process.

[0011] The beneficial effects of this utility model are as follows:

[0012] (I) By setting up a screening component, when it is necessary to change the screen plate according to the screening particle size requirements of different organic fertilizer ingredients, after removing the bolts fixing the limiting block and the sliding block, the limiting block is removed. At this time, the two sliding blocks can slide in the slide groove. Then, pinch the two sliding blocks at the same time, and the insert rod moves with the sliding block and comes out from the insertion hole. This releases the lock on the screen plate, allowing the screen plate to slide out from the sliding frame for easy replacement of screen plates with different apertures. Only two core steps, removing the bolts and pinching the sliding blocks, are needed to release the lock, shortening the screen plate disassembly time.

[0013] (ii) The equipment is equipped with a conveyor belt. When the crankshaft rotates, it synchronously drives the transmission roller to rotate, which in turn drives the conveyor belt sleeved on the outside of the transmission roller to run. The conveyor belt is located at the bottom of the screen plate and can receive qualified materials falling from the screen plate to realize the automatic conveying of the screened materials. It also conveys the qualified materials to the side opposite to the storage direction of the large-diameter materials for discharge. In this way, the screened materials can be diverted to avoid the mixing of large-diameter materials and qualified materials. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figure 1-5 This utility model provides a technical solution: an organic fertilizer batching and screening device with replaceable sieve plates, including a screening box 1, a feed hopper 2 fixedly connected to the top of the screening box 1, a maintenance cover 3 rotatably connected to the top of the screening box 1, and a screening assembly 7. The outer side of the screening assembly 7 is fixedly connected to the inner side of the screening box 1, a drive motor 4 is fixedly connected to the outer side of the screening box 1, a crankshaft 5 is fixedly connected to the output end of the drive motor 4, a connecting rod 6 is rotatably connected to the outer side of the crankshaft 5, and the end of the connecting rod 6 away from the crankshaft 5 is rotatably connected to the outer side of the screening assembly 7; the screening assembly 7 includes a sliding frame 71, a limit slider 72 is slidably connected to the bottom of the sliding frame 71, and a screen plate 73 is inserted into the inner side of the sliding frame 71. Organic fertilizer ingredients are fed into the equipment through the feed hopper 2 at the top of the screening box 1. Then, the drive motor 4 is started, and its output end drives the crankshaft 5 to rotate. When the crankshaft 5 rotates, it drives the sliding frame 71 in the screening assembly 7 to reciprocate linearly through the connecting rod 6. The limiting slider 72 can limit and guide the sliding frame 71. At the same time, the screen plate 73 reciprocates synchronously with the sliding frame 71. The organic fertilizer ingredients are graded and screened through the screen holes of the screen plate 73. Materials that meet the particle size requirements fall through the screen holes of the screen plate 73, while large-sized materials that do not meet the requirements remain on the surface of the screen plate 73. Under the action of gravity, the materials are discharged along the side of the screening box 1 away from the maintenance cover plate 3 as the screen plate 73 moves.

[0022] A sliding block 74 is slidably connected to the inner wall of the sliding frame 71 via a sliding groove 75, which is located within the wall of the sliding frame 71. A rod 77 is fixedly connected to the outer side of the sliding block 74, and a compression spring 76 is fixedly connected to the side of the sliding block 74 away from the rod 77. A limit block 78 is fixedly connected to the top of the sliding block 74 via bolts. The two sides of the crankshaft 5 are rotatably connected to the inner side of the screening box 1. The end of the connecting rod 6 away from the crankshaft 5 is rotatably connected to the outer side of the sliding frame 71. The side wall of the limit slider 72 is fixedly connected to the inner wall of the screening box 1. The outer side of the rod 77 is inserted into the inner wall of the screen plate 73 via a insertion hole 79, which is located within the side wall of the screen plate 73. When the screen plate 73 needs to be replaced according to the particle size requirements of different organic fertilizer ingredients, the top of the screening box 1 can be opened when the equipment is stopped. The maintenance cover plate 3 and the limiting block 78 are fixed to the top of the sliding block 74 by bolts, which plays an auxiliary role in fixing the position of the sliding block 74 and can prevent the sliding block 74 from being displaced due to vibration during equipment operation. After removing the bolts fixing the limiting block 78 and the sliding block 74, the limiting block 78 is removed. At this time, the two sliding blocks 74 can slide in the slide groove 75. Then, the two sliding blocks 74 are pinched at the same time, which forces the compression spring 76 to be compressed. At this time, the insertion rod 77 moves with the sliding block 74 and comes out from the insertion hole 79. This releases the lock on the screen plate 73, allowing the screen plate 73 to slide out from the sliding frame 71, so as to facilitate the replacement of screen plates 73 with different apertures. Only two core steps, removing the bolts and pinching the sliding block 74, are needed to release the lock, shortening the screen plate disassembly time.

[0023] The screening box 1 is rotatably connected to two sides of a drive roller 8. A conveyor belt 9 is fitted around the outside of the drive roller 8 and is located at the bottom of the screening plate 73. The drive roller 8 and the crankshaft 5 are driven by a pulley system. An idler roller 10 is installed on the inside of the conveyor belt 9. The two ends of the idler roller 10 are rotatably connected to the inside of the screening box 1. When the crankshaft 5 rotates, it synchronously drives the drive roller 8 to rotate, thereby driving the conveyor belt 9 fitted around the drive roller 8 to rotate. The conveyor belt 9 is located at the bottom of the screening plate 73 and can receive qualified materials falling from the screening plate 73, realizing the automatic conveying of the screened materials. It also conveys the qualified materials to the side of the screening box 1 near the maintenance cover plate 3 for discharge, thereby achieving the diversion of screened materials and preventing large-diameter particles from mixing with qualified materials. The idler roller 10 supports the conveyor belt 9 to prevent the conveyor belt 9 from deforming due to the weight of the materials and ensures the stability of the conveying process.

[0024] Working principle: During operation, the drive motor 4 provides power, driving the overall screening and conveying mechanism to work together to achieve organic fertilizer batching and screening. The specific process is as follows:

[0025] Organic fertilizer ingredients are fed into the equipment through the feed hopper 2 at the top of the screening box 1. Then, the drive motor 4 is started, and its output end drives the crankshaft 5 to rotate. When the crankshaft 5 rotates, it can drive the sliding frame 71 in the screening assembly 7 to reciprocate linear motion through the connecting rod 6. The limiting slider 72 can limit and guide the sliding frame 71.

[0026] Simultaneously, the screening plate 73 reciprocates synchronously with the sliding frame 71. The organic fertilizer ingredients are graded and screened through the screen holes of the screening plate 73. Materials that meet the particle size requirements fall through the screen holes of the screening plate 73, while large-sized materials that do not meet the requirements remain on the surface of the screening plate 73. Under the action of gravity, the materials are discharged along the side of the screening box 1 away from the maintenance cover plate 3 as the screening plate 73 moves.

[0027] During this process, the crankshaft 5 rotates synchronously, driving the transmission roller 8 to rotate, which in turn drives the conveyor belt 9 sleeved on the outside of the transmission roller 8 to operate. The conveyor belt 9 is located at the bottom of the screen plate 73 and can receive qualified materials falling from the screen plate 73, realizing the automatic conveying of the screened materials and conveying the qualified materials to the side of the screening box 1 near the maintenance cover plate 3 for discharge. This achieves the diversion of the screened materials and avoids the mixing of large-diameter particles with qualified materials. The idler roller 10 supports the conveyor belt 9 to prevent the conveyor belt 9 from deforming due to the weight of the materials and ensures the stability of the conveying process.

[0028] When the screen plate 73 needs to be replaced according to the screening particle size requirements of different organic fertilizer ingredients, the maintenance cover 3 on the top of the screening box 1 can be opened when the equipment is stopped. The limiting block 78 is fixed to the top of the sliding block 74 by bolts, which plays an auxiliary role in fixing the position of the sliding block 74 and can prevent the sliding block 74 from being displaced due to vibration during the operation of the equipment. After removing the bolts fixing the limiting block 78 and the sliding block 74, the limiting block 78 can be removed. At this time, the two sliding blocks 74 can slide in the slide groove 75. Then, the two sliding blocks 74 are pinched at the same time, which forces the compression spring 76 to be compressed. At this time, the insertion rod 77 moves with the sliding block 74 and comes out from the insertion hole 79. This releases the lock on the screen plate 73, allowing the screen plate 73 to slide out from the sliding frame 71, so as to replace the screen plate 73 with a different aperture. Only two core steps are required to release the lock: removing the bolts and pinching the sliding block 74, which shortens the screen plate disassembly time.
