Description

Technical Field

[0001] This utility model relates to the field of chicken feed processing, specifically a multi-stage crushing and screening machine for chicken feed. Background Technology

[0002] Chicken feed is the core carrier of nutrients required for the growth of chickens and poultry. Its nutrient supply mainly depends on feed. Currently, the market supply is mainly based on artificial mass breeding. However, chickens and poultry at different growth stages have different requirements for feed particle size: chicks need to eat fine powder feed, and as chickens and poultry grow, the feed particle size needs to increase in tandem to match their growth needs. In order to improve processing efficiency, the industry often uses multi-stage crushing and screening machines to produce chicken feed of different particle sizes.

[0003] A search revealed Chinese Patent Publication No. CN219441980U, which discloses a multi-stage chicken feed grinding and screening machine. The machine includes a primary grinding chamber and a secondary grinding chamber, arranged vertically and each containing crushing components. It also includes a chicken feed conveying component and a chicken feed discharging component. The conveying component connects the primary and secondary grinding chambers and performs a screening function, discharging the screened feed and conveying the unscreened feed to the secondary grinding chamber. The discharging component is located at the bottom of the secondary grinding chamber and also performs a screening function. This invention, by incorporating the chicken feed conveying and discharging components, allows for the processing of chicken feed with three different particle sizes, catering to chickens at different growth stages and meeting their needs for mass chicken farming.

[0004] Although the equipment can process chicken feed of various particle sizes at the same time, it has obvious defects: its screening plate is a fixed design, and the screening process relies solely on the vibration of the equipment itself to improve efficiency. Due to the small vibration amplitude of the screening plate, the overall screening efficiency is ultimately low. Therefore, a multi-stage crushing and screening machine for chicken feed is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background art, this utility model proposes a multi-stage crushing and screening machine for chicken feed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a multi-stage crushing and screening machine for chicken feed includes a box body. A crushing roller is rotatably connected to the inner wall of the top of the box body. A driving mechanism is fixedly installed on the side wall of the top of the box body, and the crushing roller is driven by the driving mechanism. A sealing plate is inserted into the inner wall of the box body. A sliding shell is provided on the inner wall of the sealing plate. A screening plate is bolted to the inner wall of the sliding shell. The screening plate is set on the inner wall of the box body. A V-shaped guide plate is fixedly connected to the bottom of the screening plate on the inner wall of the box body. A fixing rod is rotatably connected to the inner wall of the top of the box body. One end of the fixing rod is fixedly connected to the end of the crushing roller. A roller is fixedly connected to the other end of the fixing rod. A rotating rod is rotatably connected between the screening plate and the V-shaped guide plate on the inner wall of the box body. An extrusion block is fixedly connected to one end of the rotating rod. A roller is fixedly connected to the other end of the rotating rod. A belt is slidably connected to the inner wall of the roller. The inner wall of the other end of the belt is slidably connected to the inner wall of the roller.

[0007] Preferably, the inner wall of the box is provided with a rectangular groove, and the inner wall of the sealing plate is elastically connected to an insert plate by a spring. The end of the insert plate is inserted into the inner wall of the rectangular groove, and the outer wall of the insert plate is slidably connected to the inner wall of the sealing plate. One end of the spring is fixedly connected to the side wall of the insert plate, and the other end of the spring is fixedly connected to the inner wall of the sealing plate. A push handle is fixedly connected to the side wall of the insert plate, and the outer wall of the end of the push handle is slidably connected to the inner wall of the sealing plate.

[0008] Preferably, the sealing plate has a groove on its side wall, the outer wall of the sliding shell is slidably connected to the inner wall of the groove, and a second spring is fixedly connected to both the top and bottom sides of the sliding shell, with the other end of the second spring fixedly connected to the inner wall of the groove.

[0009] Preferably, a crushing roller 2 is provided on the inner wall of the box at the bottom side of the V-shaped guide plate 1, a screening plate 2 is provided on the bottom of the box at the bottom side of the crushing roller 2, a V-shaped guide plate 2 is fixedly connected to the inner wall of the box at the bottom side of the screening plate 2, a discharge shell 1 is fixedly connected to the side wall of the top of the box, a discharge shell 2 is fixedly connected to the side wall of the bottom of the box, and a discharge shell 3 is fixedly connected to the bottom side of the box.

[0010] Preferably, two sets of sealing plates and sliding shells are provided, with another set of sealing plates and sliding shells provided on the inner wall of the bottom of the box. The second screening plate is installed on the inner wall of the box through the cooperation of the other set of sealing plates and sliding shells.

[0011] Preferably, two sets of roller one, belt, roller two, fixed rod, rotating rod, and extrusion block are provided, and another set of roller one, belt, roller two, fixed rod, rotating rod, and extrusion block are arranged in corresponding positions between crushing roller two and screening plate two.

[0012] Preferably, the extrusion block is configured as a cam shape, and the end of the rotating rod is specifically fixed to the side wall of the end of the extrusion block.

[0013] The advantages of this utility model are: by cooperating with the set roller one, belt, roller two, fixed rod and sliding shell, the vibration efficiency of the screening plate can be improved, and its screening effect can be further improved. Moreover, it is driven by crushing roller, which eliminates the need to add a separate drive mechanism and reduces installation costs.

[0014] This invention uses a drive mechanism to rotate a crushing roller, which in turn drives a roller to rotate. The roller then drives a second roller via a belt, causing the rotating rod and the extrusion block to rotate as well. The extrusion block repeatedly strikes the screening plate, causing the screening plate to slide along the inner wall of the chute. This improves the screening efficiency of the screening plate and solves the problem that some multi-stage crushing and screening machines for chicken feed have fixed screening plates, relying solely on the vibration of the equipment itself to increase efficiency. Due to the small vibration amplitude of the screening plate, the overall screening efficiency is low. Attached Figure Description

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.

[0019] The following is in conjunction with the appendix Figure 1 - Figure 6 This application will be described in further detail. This application discloses a multi-stage grinding and screening machine for chicken feed. (Refer to...) Figure 1 - Figure 3 and Figure 5 - Figure 6A multi-stage crushing and screening machine for chicken feed includes a housing 1. A crushing roller 3 is rotatably connected to the inner wall of the top of the housing 1. A drive mechanism 2 is fixedly installed on the side wall of the top of the housing 1, and the crushing roller 3 is driven by the drive mechanism 2. A sealing plate 7 is inserted into the inner wall of the housing 1. A sliding shell 19 is provided on the inner wall of the sealing plate 7. A screening plate 14 is bolted to the inner wall of the sliding shell 19. The screening plate 14 is located on the inner wall of the housing 1, and the inner wall of the housing 1 is located at the bottom of the screening plate 14. A V-shaped guide plate 15 is fixedly connected to the inner wall of the top of the box 1. A fixing rod 12 is rotatably connected to the inner wall of the box 1. One end of the fixing rod 12 is fixedly connected to the end of the crushing roller 3. A roller 9 is fixedly connected to the other end of the fixing rod 12. A rotating rod 13 is rotatably connected to the inner wall of the box 1 between the screening plate 14 and the V-shaped guide plate 15. An extrusion block 25 is fixedly connected to one end of the rotating rod 13. A roller 11 is fixedly connected to the other end of the rotating rod 13. A belt 10 is slidably connected to the inner wall of the roller 11. The belt 10 is further... One end of the inner wall is slidably connected to the inner wall of roller 9. When processing chicken feed, it can be placed inside the box 1 and the drive mechanism 2 is started to drive the crushing roller 3 to rotate. The crushing roller 3 will crush the chicken feed. The crushed chicken feed will fall onto the screening plate 14, be filtered through the screening plate 14, and fall onto the V-shaped guide plate 15 and be discharged. The unfiltered feed will fall into the next crushing and screening process along the slope of the screening plate 14. In this process, the crushing roller 3 will drive the fixed rod 12 and roller 9 to rotate. Roller 9 will drive roller 11 to rotate through belt 10. Roller 11 will drive the rotating rod 13 to rotate. The rotating rod 13 will drive the extrusion block 25 to rotate. The extrusion block 25 will repeatedly squeeze the screening plate 14 to move up and down, thereby increasing the vibration force of the screening plate 14. This will improve the screening effect and increase the processing efficiency of the multi-stage crushing and screening machine.

[0020] Reference Figure 1 and Figure 4The inner wall of the housing 1 has a rectangular groove 16. An insert plate 18 is elastically connected to the inner wall of the sealing plate 7 via a spring 17. The end of the insert plate 18 is inserted into the inner wall of the rectangular groove 16, and the outer wall of the insert plate 18 is slidably connected to the inner wall of the sealing plate 7. One end of the spring 17 is fixed to the side wall of the insert plate 18, and the other end of the spring 17 is fixed to the inner wall of the sealing plate 7. A push handle 8 is fixed to the side wall of the insert plate 18, and the outer wall of the end of the push handle 8 is slidably connected to the inner wall of the sealing plate 7. During operation, the screening plate 14 needs to be cleaned after a period of use. During maintenance, the push handle 8 can be used to move the insert plate 18, causing it to disengage from the inner wall of the rectangular groove 16. As the insert plate 18 moves, it will compress the spring 17. Then, the push handle 8 can be pulled to move the sealing plate 7, causing the sealing plate 7 to move the screening plate 14 out from the inner wall of the housing 1. The screening plate 14 can then be removed from the sealing plate 7. This eliminates the need for workers to go deep into the inner wall of the equipment to disassemble and maintain the screening plate 14, thus improving the convenience of disassembly.

[0021] Reference Figure 5 The sealing plate 7 has a sliding groove 21 on its side wall. The outer wall of the sliding shell 19 is slidably connected to the inner wall of the sliding groove 21. Springs 20 are fixed to the top and bottom sides of the sliding shell 19. The other end of the springs 20 is fixed to the inner wall of the sliding groove 21. When the screening plate 14 moves up and down, it will drive the sliding shell 19 to slide on the inner wall of the sliding groove 21. At the same time, the sliding shell 19 will repeatedly stretch and compress multiple sets of springs 20. The springs 20 will make the vibration force of the sliding shell 19 stronger through their own elasticity, further improving the screening efficiency of the screening plate 14.

[0022] Reference Figure 1 - Figure 3 The inner wall of the housing 1 is equipped with a crushing roller 22 located on the bottom side of the V-shaped guide plate 15. The bottom of the housing 1 is equipped with a screening plate 23 located on the bottom side of the crushing roller 22. The inner wall of the housing 1 is fixedly connected to the bottom side of the screening plate 23. The top side wall of the housing 1 is fixedly connected to the discharge shell 4. The bottom side wall of the housing 1 is fixedly connected to the discharge shell 5. The bottom side of the housing 1 is fixedly connected to the discharge shell 6. During operation, the chicken feed rolling off the screening plate 14 will fall onto the crushing roller 22. The crushing roller 22 is driven to rotate by another set of drivers to crush the chicken feed a second time. The crushed chicken feed will fall onto the screening plate 23 for screening. The screened feed will fall back onto the V-shaped guide plate 24 and be discharged through the discharge shell 25. The feed that cannot be screened will be discharged through the discharge shell 6. This ensures the continuity of the structure and improves practicality.

[0023] Reference Figure 3 and Figure 5There are two sets of sealing plates 7 and sliding shells 19. Another set of sealing plates 7 and sliding shells 19 is set on the inner wall of the bottom of the box 1. The screening plate 23 is specifically installed on the inner wall of the box 1 through the cooperation of the other set of sealing plates 7 and sliding shells 19. During operation, the two sets of sealing plates 7 and sliding shells 19 allow the screening plate 23 to be quickly disassembled and maintained, just like the screening plate 14, thus improving convenience.

[0024] Reference Figure 3 Two sets of roller 19, belt 10, roller 21, fixed rod 12, rotating rod 13, and extrusion block 25 are provided. Another set of roller 19, belt 10, roller 21, fixed rod 12, rotating rod 13, and extrusion block 25 are set in corresponding positions between crushing roller 22 and screening plate 23. During operation, the vibration screening effect of screening plate 23 is further improved by the cooperation of the two sets of roller 19, belt 10, roller 21, fixed rod 12, rotating rod 13, and extrusion block 25.

[0025] Reference Figure 6 The extrusion block 25 is cam-shaped, and the end of the rotating rod 13 is fixed to the side wall of the end of the extrusion block 25. When working, the extrusion block 25 rotates and will smoothly extrude the screening plate 14 through its cam shape to move up and down, which improves its practicality.

[0026] Working principle: When chicken feed needs to be processed, it can be placed inside the housing 1, and the drive mechanism 2 is started to drive the crushing roller 3 to rotate. The crushing roller 3 will crush the chicken feed. The crushed chicken feed will fall onto the screening plate 14, be filtered through the screening plate 14, and fall onto the V-shaped guide plate 15 for discharge. Unfiltered feed will fall onto the crushing roller 22 along the slope of the screening plate 14. The crushing roller 22 is driven to rotate by another set of drivers to crush the chicken feed a second time. The crushed chicken feed will fall onto the screening plate 23 for screening. The screened feed will fall back onto the V-shaped guide plate 24 and be discharged through the discharge shell 25. The feed that cannot be screened will be discharged through the discharge shell 36. This ensures the continuity of the structure and improves practicality.

[0027] During this process, the crushing roller 3 will drive the fixed rod 12 and the roller 9 to rotate. The roller 9 will drive the roller 11 to rotate via the belt 10. The roller 11 will drive the rotating rod 13 to rotate. The rotating rod 13 will drive the extrusion block 25 to rotate. The extrusion block 25 will repeatedly extrude the screening plate 14 to move up and down, thereby increasing the vibration force of the screening plate 14. The screening plate 23 will also undergo the same movement as above.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
