Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically a screening machine for organic fertilizer processing. Background Technology

[0002] As a core grading device in organic fertilizer production lines, screening machines are specifically designed for the pretreatment of organic fertilizer raw materials and the control of finished product particle size. Through working principles such as screen grading, mechanical vibration, or drum rotation, they can separate the particle size and remove impurities of organic fertilizer materials with different moisture contents and viscosity, thereby achieving the classification of finished organic fertilizer products into specifications (such as coarse particles, medium particles, fine powder, etc.), ensuring fertilizer uniformity and application effect. This type of screening machine is widely used in large-scale organic fertilizer production plants and small and medium-sized fertilizer processing workshops, and is a key link connecting the crushing, mixing, and packaging processes of organic fertilizer.

[0003] However, the above implementation methods still have the following problems. In terms of grading capability, most traditional screening machines only have single-stage screening function, and multiple repeated screenings are required to achieve the separation of multiple particle sizes. This not only increases the equipment investment cost and production time, but also easily causes losses during material transfer. Furthermore, some screening machines, due to their simple screen structure design and lack of targeted anti-clogging mechanisms, are prone to screen hole blockage and insufficient fine material penetration when facing organic fertilizer materials with high moisture content or strong viscosity. This leads to a decrease in grading accuracy, and the finished product contains excessive coarse particles or impurities, which not only affects the fertilizer application effect, but may also cause wear and tear on subsequent packaging equipment. This fails to meet the quality requirements of the diversified market for organic fertilizer products with different particle sizes, so improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a screening machine for organic fertilizer processing, which has the advantage of grading and screening.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screening machine for organic fertilizer processing, comprising a machine body, a fixed frame fixedly installed on the right side of the machine body, a servo motor fixedly connected to the right side of the fixed frame, a rotating shaft fixedly installed at the other end of the output shaft of the servo motor, two sprockets fixedly connected to the left side of the rotating shaft, the two sprockets being connected by a chain drive, a connecting rod fixedly installed on the left side of the chain, a pushing block fixedly connected to the left side of the connecting rod, and a movable connection on the outer surface of the pushing block. The screen has a discharge plate fixedly installed on its left side. A feeding frame is movably sleeved on the outer surface of the screen. A discharge chute is opened on the right side inside the feeding frame. A support frame is fixedly connected to the right side of the top of the feeding frame. A fixed column is fixedly connected inside the support frame. A pushing column is movably sleeved inside the fixed column. A compression spring is fixedly installed at the top of the pushing column. The top of the compression spring is fixedly connected to the top of the inside of the fixed column. The bottom of the pushing column is movably connected to the top of the screen. A discharge pipe is fixedly installed on the right side of the bottom of the machine body.

[0006] As a preferred embodiment of the present invention, a sealing cover is fixedly installed on the top of the body, and a sealing plate is movably sleeved inside the sealing cover.

[0007] As a preferred embodiment of this invention, a limiting groove is provided at the top of the sealing plate, and sliders are fixedly connected to both the front and rear sides of the sealing plate.

[0008] In a preferred embodiment of this invention, the inner surface of the sealing cover is movably connected to the outer surface of the slider, and a handle is fixedly installed on the right side of the sealing plate.

[0009] As a preferred embodiment of this utility model, a fixing block is fixedly installed at the top of the sealing cover, a limiting block is movably sleeved inside the fixing block, and the outer surface of the limiting block is movably sleeved with the inner surface of the sealing cover and the limiting groove.

[0010] As a preferred embodiment of this utility model, a reset spring is fixedly connected to the top end of the limiting block, and the top end of the reset spring is fixedly connected to the top end inside the fixing block.

[0011] As a preferred embodiment of this utility model, a pull rod is fixedly connected to the right side of the limiting block, and the outer end of the pull rod passes through the fixed block and extends to the outside of the fixed block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the setting of a screen, a pushing column, a pushing block, and a feeding frame, allows the screen to move downwards. When the screen moves downwards, the elastic force generated by the compression spring pushes the screen through the pushing column, further accelerating the downward speed of the screen and causing it to vibrate, thus preventing clogging. The rotation of the pushing block causes the screen to swing up and down, and the fertilizer on the screen bounces with the swing, further improving the screening effect. The fertilizer after preliminary screening slides through the feeding frame, which has an inclined internal design. The sliding fertilizer falls through the discharge chute into the screen below for secondary screening. The two screens have different apertures, allowing for multi-stage screening. The whole system can efficiently complete multi-specification grading. By simultaneously separating products of different particle sizes through the double-layer screen, there is no need for repeated screening, which greatly saves labor time. Furthermore, the up-and-down swing of the screen, combined with the elastic force of the compression spring, can reduce clogging and ensure screening efficiency.

[0013] 2. This utility model, by setting a limiting block, a return spring, a sealing cover, and a sealing plate, allows the operator to move the limiting block by pulling the lever. During the movement of the limiting block, it will disengage from the limiting groove. At this time, the operator can hold the handle and move the sealing plate. During the movement of the sealing plate, the size of the feed inlet can be adjusted. After the adjustment is completed, the spring force of the return spring will drive the limiting block to return to its original position. At this time, the limiting block will be connected to the limiting groove, and the sealing cover and sealing plate will also be fixed. The whole system can adapt to different material states. When the moisture content or viscosity of the material changes, the feed rate can be controlled by adjustment to avoid material accumulation and blockage. Attached Figure Description

[0016] 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.

[0017] like Figures 1 to 6 As shown, this utility model provides a screening machine for organic fertilizer processing, including a machine body 1. A fixed frame 2 is fixedly installed on the right side of the machine body 1. A servo motor 3 is fixedly connected to the right side of the fixed frame 2. A rotating shaft 4 is fixedly installed at the other end of the output shaft of the servo motor 3. A sprocket 5 is fixedly connected to the left side of the rotating shaft 4. There are two sprockets 5, which are connected by a chain 6. A connecting rod 7 is fixedly installed on the left side of the chain 6. A pushing block 8 is fixedly connected to the left side of the connecting rod 7. A screen 9 is movably connected to the outer surface of the pushing block 8. A screen 9 is fixedly installed on the left side of the screen 9. The discharge plate 10 and the screen 9 are movably fitted with a feeding frame 11. The right side of the inside of the feeding frame 11 is provided with a discharge chute 12. The right side of the top of the feeding frame 11 is fixedly connected with a support frame 13. The inside of the support frame 13 is fixedly connected with a fixed column 14. The inside of the fixed column 14 is movably fitted with a pushing column 15. The top of the pushing column 15 is fixedly installed with a compression spring 16. The top of the compression spring 16 is fixedly connected with the top of the inside of the fixed column 14. The bottom of the pushing column 15 is movably connected with the top of the screen 9. The right side of the bottom of the machine body 1 is fixedly installed with a discharge pipe 17.

[0018] During operation, the operator feeds fertilizer into the machine body 1 for screening and processing. The fertilizer falls onto the screen 9 for sieving. The inclined design of the screen 9 causes the fertilizer to continuously roll. The servo motor 3 is started, and its output shaft drives the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, the sprocket 5 and chain 6 will rotate. At this time, the connecting rod 7 and the push block 8 also rotate together. The push block 8 is in contact with the screen 9 and has an elliptical design. As the push block 8 rotates, it causes the screen 9 to swing up and down. At this time, the fertilizer on the screen 9 jumps with the swing, further improving the screening effect. The fertilizer after the initial screening falls into the screen 9 below through the discharge chute 12 for secondary screening. The two screens 9 have different apertures, which can separate fertilizers of different particle sizes and ensure the uniformity of the product.

[0019] The top of the body 1 is fixedly equipped with a sealing cover 18, and a sealing plate 19 is movably sleeved inside the sealing cover 18.

[0020] The sealing cover 18 has a feed inlet, and the size of the feed inlet can be adjusted by the sealing plate 19 to meet the needs of subsequent use.

[0021] The sealing plate 19 has a limiting groove 20 at its top, and sliders 21 are fixedly connected to both the front and rear sides of the sealing plate 19.

[0022] There are two sliders 21, which limit the sealing plate 19 and make it move along a preset trajectory.

[0023] The inner surface of the sealing cover 18 is movably connected to the outer surface of the slider 21, and a handle 26 is fixedly installed on the right side of the sealing plate 19.

[0024] The operator moves the sealing plate 19 by holding the handle 26, which facilitates the subsequent adjustment of the feed inlet size.

[0025] The top of the sealing cover 18 is fixedly installed with a fixing block 22, and the inside of the fixing block 22 is movably sleeved with a limiting block 23. The outer surface of the limiting block 23 is movably sleeved with the inner surface of the sealing cover 18 and the limiting groove 20.

[0026] The sealing cover 18 and the sealing plate 19 are fixed by the limiting block 23, and the sealing plate 19 is fixed by the connection between the limiting block 23 and the limiting groove 20.

[0027] Among them, the top end of the limiting block 23 is fixedly connected to the return spring 24, and the top end of the return spring 24 is fixedly connected to the top end inside the fixing block 22.

[0028] The return spring 24 causes the limit block 23 to move. When the limit block 23 moves upward and opens the fixed position, the return spring 24 will deform.

[0029] The right side of the limiting block 23 is fixedly connected to a pull rod 25, the outer end of which passes through the fixing block 22 and extends to the outside of the fixing block 22.

[0030] The operator moves the limit block 23 by holding the lever 25, thereby disengaging the limit block 23 from the limit groove 20.

[0031] Working principle and usage process of this utility model: During operation, the operator feeds fertilizer into the machine body 1 for screening and processing. The fertilizer falls onto the screen 9 for sieving. The inclined design of the screen 9 causes the fertilizer to continuously roll. The servo motor 3 is started, and its output shaft drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the sprocket 5 to rotate, which in turn drives the chain 6 to rotate. The chain 6 then drives the sprocket 5 on the other side to rotate. The rotation of the sprocket 5 drives the connecting rod 7 and the pushing block 8 to rotate together. The pushing block 8 is in contact with the screen 9 and has an elliptical design. As the pushing block 8 rotates, it causes the screen 9 to swing up and down. The screen 9 moves upwards. When the screen 9 moves, it will drive the push column 15 to move together, compressing the squeeze spring 16. When the screen 9 moves downward, the elastic force generated by the squeeze spring 16 will further accelerate the falling speed of the screen 9, causing the screen 9 to vibrate and avoid clogging. At this time, the fertilizer on the screen 9 will bounce with the swing, further improving the screening effect. The fertilizer after preliminary screening slides through the feed rack 11. The feed rack 11 has an inclined design inside. The sliding fertilizer will fall into the screen 9 below through the discharge chute 12 for secondary screening. The two screens 9 have different apertures, which can perform multi-stage screening to separate fertilizers of different particle sizes and ensure the uniformity of the product.

[0032] When the feed inlet size needs to be adjusted, the operator moves the limit block 23 by pulling the lever 25. During the movement, the limit block 23 will disengage from the limit groove 20, opening the fixed sealing cover 18 and sealing plate 19. At this time, the operator holds the handle 26 to move the sealing plate 19. During the movement of the sealing plate 19, the size of the feed inlet can be adjusted. After the adjustment is completed, the limit block 23 will be reset by the elastic force of the return spring 24. At this time, the limit block 23 will be connected to the limit groove 20, and the sealing cover 18 and sealing plate 19 will also be fixed. The adjustable feed inlet size design meets the usage needs.
