Description

Technical Field

[0001] This utility model relates to the field of crushing technology, and in particular to a raw material crushing particle size control device for organic fertilizer production line. Background Technology

[0002] In the production of organic fertilizer, the particle size of raw materials is one of the key factors affecting fermentation efficiency and product quality. Organic raw materials such as straw and livestock manure usually need to be mechanically crushed to process them into fine particles suitable for fermentation. Traditional crushing equipment is usually equipped with replaceable screens, and the particle size is controlled by adjusting the screen aperture (usually 5-20mm) to meet the characteristics of different raw materials and process requirements. For example, for fine raw materials with low fiber content and easy fermentation, a fine screen of 5-10mm is usually selected; while for high-fiber or difficult-to-crush materials, a coarse screen of 15-20mm is required to ensure crushing efficiency and particle uniformity.

[0003] However, the existing screen replacement process has the following problems: screens are usually fixed by bolts or clips, and multiple fasteners need to be removed with tools during replacement, which is not only time-consuming and labor-intensive, but also increases equipment downtime and affects production efficiency. Therefore, there is an urgent need to design a raw material crushing particle size control device for organic fertilizer production lines to achieve rapid screen replacement, reduce downtime, and improve production efficiency.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1 - Figure 6As shown, a raw material crushing particle size control device for an organic fertilizer production line includes a particle size control screen 1, which is movably inserted into a housing 2. Two fixing blocks 3 are symmetrically fixedly installed on the housing 2. A connecting frame 4 is fixedly installed at one end of the particle size control screen 1 and on the outside of the housing 2. The connecting frame 4 consists of a base rod 15 and connecting blocks 16. There are two connecting blocks 16, which are symmetrically fixedly installed at one end of the base rod 15. Two fixing parts 5 are symmetrically installed on the base rod 15. The fixing parts 5 are simultaneously inserted into the housing 2. Inside the fixing block 3, the fixing component 5 consists of a square rod 19, a stop frame 20, a push-pull plate 21, and a spring 22. The stop frame 20 is fixedly sleeved on the square rod 19, the push-pull plate 21 is fixedly installed on the inner end of the square rod 19, and the spring 22 is fixedly installed on the inner end of the push-pull plate 21. The housing 2 consists of a base shell 9, a bottom frame plate 10, and a top frame plate 11. The bottom frame plate 10 is fixedly installed on the lower end of the base shell 9, and the top frame plate 11 is fixedly installed on the upper end of the base shell 9. A slot 12 is provided on one inner wall of the base shell 9. A slot 13 is provided on the other side wall of the base shell 9. A feed hopper 6 is fixedly installed on the upper end of the top frame plate 11, and a bottom frame plate 10 is fixedly installed on the upper end of the support 7. A crushing component 8 is installed inside the base shell 9. The crushing component 8 is fixedly connected to the output shaft of the motor installed on the support 7. When in use, the particle size control screen 1 is inserted into the slot 13 and slot 12 on the shell 2 at the same time, ensuring that the base rod 15 of the connecting frame 4 is located between the two fixed blocks 3. At the same time, the square rod 19 on the fixing member 5 is inserted into the square hole 14 of the fixing block 3 under the elastic force of the spring 22. At this time, the particle size control screen 1 is fixed. During use, raw materials are added through the feed hopper 6, and the motor is started to drive the crushing component 8 to crush. The crushed material is discharged through the screen hole of the particle size control screen 1 to achieve particle size control. When the screen needs to be replaced, the push-pull plate 21 is pressed to make the square rod 19 exit the square hole 14, and the particle size control screen 1 can be pulled out of the shell 2. After replacing the new particle size control screen 1, the above fixing steps are repeated.

[0024] Specifically, the fixing block 3 is fixedly installed on the upper end of the bottom frame plate 10. The fixing block 3 has a square hole 14. The particle size control screen 1 is movably inserted into the through groove 13 and slot 12 opened on the base shell 9. The connecting block 16 on the connecting frame 4 is fixedly connected to the particle size control screen 1. The base rod 15 is located between the two fixing blocks 3. The base rod 15 has two symmetrically opened receiving grooves 17, which pass through the base rod 15 vertically. The two ends of the base rod 15 have two symmetrically opened through holes 18, which communicate with the receiving grooves 17. The spring 22 and the push-pull plate 21 on the fixing part 5 are both movably installed in the receiving grooves 17. The square rod 19 passes through the through hole 18 and is simultaneously inserted into the square hole 14. The baffle 20 is located between the base rod 15 and the fixing block 3. During installation, the two push-pull plates 21 are pressed simultaneously with fingers to compress the spring 22, causing the square rod 19 to move inward. At this time, the push-pull plates 21 Next, the end of the particle size control screen 1 needs to be inserted into the housing 2 through the slot 13 and pushed along the slot 12 until the base rod 15 is located between the fixing blocks 3, so that the square rod 19 is aligned with the square hole 14. Then, the push-pull plate 21 is released. At this time, under the elastic force of the spring 22, the square rod 19 will be inserted into the square hole 14, until the baffle 20 contacts the fixing block 3. During the crushing process, the raw material enters the housing 2 from the feed hopper 6, the crushing component 8 rotates and crushes the material, and qualified particles are discharged through the particle size control screen 1. To replace the screen, after the equipment stops, press the push-pull plate 21 to make the square rod 19 exit from the square hole 14. Then, pull out the old particle size control screen 1 and insert the new particle size control screen 1. Repeat the above fixing steps to install and fix it. During operation, it is necessary to ensure that the equipment is stopped. The elasticity of the spring 22 needs to be checked regularly. After the particle size control screen 1 is installed, manually shake it to confirm that there is no looseness, so as to ensure production efficiency and safety.

[0025] Finally, by setting a connecting frame 4 on the particle size control screen 1, setting a fixing block 3 on the housing 2, and setting a fixing part 5 on the connecting frame 4, the disassembly and assembly of the particle size control screen 1 can be made simple and convenient. Moreover, the disassembly and assembly process does not require the use of tools and can be completed by hand, thereby improving the disassembly and assembly efficiency of the particle size control screen 1, reducing the downtime of the crushing equipment, and ultimately improving the crushing efficiency of organic fertilizer raw materials.

[0026] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
