Description

Technical Field

[0001] This utility model relates to the field of feed feeder technology, specifically a feed feeder. Background Technology

[0002] Feed feeders are needed in many stages of feed production and processing to control the stable delivery of materials. The working status of feed feeders plays an important role in ensuring the smooth production of feed and the stable quality of feed products.

[0003] According to a feed feeder disclosed in the public notice (Announcement No.: CN221165042U), the aforementioned application describes a feeder in which protrusions are evenly arranged inside the crushing rollers, and the individual crushing rollers rotate in opposite directions via a first figure-eight belt. Upon starting a first motor, the feed placed inside the connecting assembly undergoes initial crushing. The connecting column and the baffle plate are arranged to rotate relative to each other, with the lower end of the baffle plate fitting against the outer surface of the crushing rollers. The crushed feed falls into the feed housing through the connecting assembly. Simultaneously, the drive motor moves the second figure-eight belt, causing the rollers to rotate in the opposite direction. This causes the baffle plate to rotate outside the connecting column and fit against the surface of the crushing rollers, resulting in a second crushing process. This reduces the volume of the feed, significantly decreasing the particle size after crushing, thus preventing clogging and ensuring the normal operation of the feed feeder.

[0004] However, in actual use, the above-mentioned equipment can achieve the effect of crushing feed by rotating in opposite directions between the individual crushing rollers through the first figure-eight belt. However, in actual use, when facing large quantities of high-intensity feed, the first figure-eight belt is very likely to slip, and the requirements for the installation tension of the belt are very high. In a feed environment with a lot of dust, the belt teeth are prone to dirt accumulation and wear, resulting in reduced transmission efficiency, abnormal noise, or even tooth skipping. In view of this, we propose a feed feeder. Utility Model Content

One end of the mounting plate is hinged to the outer surface of the convex shaft. The other end of the mounting plate is hinged to the inner wall of the connecting block.

[0012] Preferably, the second motor is a dual-head motor, and the size of the sieve plate is smaller than the internal size of the device body, and the difference in size is controlled within the diameter range of the sieve holes of the sieve plate, and the shape of the sieve plate is set to arc.

[0013] Preferably, a rotating gear is fixedly connected to the output end of the second motor away from the cam shaft. A fixed gear meshes with the outer wall of the rotating gear.

This ensures that only materials that meet the particle size requirements can be discharged through the discharge port. The arc-shaped screen plate design facilitates material dispersion and rolling, improving screening efficiency. Attached Figure Description

[0026] like Figures 1-7 As shown, this utility model provides a technical solution: a feed feeder, including a device body 1, a feeding port 11 on the upper surface of the device body 1, a discharge port 12 on the side wall of the device body 1, a support leg 13 fixedly connected to the side wall of the device body 1, and a crushing mechanism 2 inside the device body 1. The crushing mechanism 2 includes: a mounting part 21, a first motor 22, a connecting gear 23, a fixed shaft 24, a first transmission belt 25, a connecting shaft 26, a crushing roller 27, a fixed rod 28, a spiral spring 29, a connecting cylinder 210, and a flap 211.

[0027] In one embodiment of this utility model, the side wall of the mounting member 21 is fixedly connected to one outer wall of the device body 1. A first motor 22 is fixedly connected to the end of the mounting member 21 away from the device body 1. A connecting gear 23 is fixedly connected to the output end of the first motor 22. A fixed shaft 24 is fixedly connected to the inner wall of the connecting gear 23. The outer surface of the output end of the first motor 22 is driven by the inner wall of the first transmission belt 25. A connecting shaft 26 is driven by the inner wall of the first transmission belt 25. The inner wall of the crushing roller 27 is fixedly connected to the outer wall of the fixed shaft 24. The end of the connecting shaft 26 closest to the device body 1 is fixedly connected to... A fixed rod 28 is attached, and one end of a spiral spring 29 is fixedly connected to the outer surface of the fixed rod 28. The other end of the spiral spring 29 is fixedly connected to the inner wall of the connecting cylinder 210. A flap 211 is fixedly connected to the outer wall of the connecting cylinder 210. Two sets of connecting gears 23 are provided, and the two sets of connecting gears 23 are distributed in a mirror image symmetrically inside the mounting component 21. The outer surfaces of the two sets of connecting gears 23 mesh with each other. The ends of the fixed shaft 24 and the fixed rod 28 away from the first motor 22 are rotatably connected to one end inside the device body 1. Both the fixed rod 28 and the fixed shaft 24 are located at the ends away from the first motor 22. Equipped with a protective casing, the first motor 22 drives the connecting gear 23 to rotate, simultaneously driving another set of mirror-symmetrically arranged connecting gears 23 to rotate in the same or opposite directions. Furthermore, it enables synchronous driving of the fixed shaft 24. The rotating fixed shaft 24 allows the dual crushing rollers 27 to rotate synchronously in opposite directions, efficiently crushing the input feed and effectively preventing clumping or large particles from being directly discharged. When the first motor 22 drives the connecting gears 23 to rotate, the first transmission belt 25 drives the connecting shaft 26 to rotate, and the rotating connecting shaft 26 drives the fixed shaft 27 to rotate. When the fixed rod 28 rotates, it drives the connecting cylinder 210 and the flap 211 to rotate. In conjunction with the screen plate 32, it can agitate and lift feed that does not meet the size requirements. The feed that does not meet the size requirements and is pushed onto the upper surface of the screen plate 32 is crushed again by the crushing roller 27. At this time, when encountering feed with high strength that makes the flap 211 unable to function, the connecting cylinder 210 will drive the spiral spring 29 to rotate, absorbing the rotation driven by the fixed rod 28. This can prevent wear and consumption of the first transmission belt 25, and further increase the service life and reliability of the equipment.

[0028] In addition, a screening mechanism 3 is provided inside the device body 1. The screening mechanism 3 includes a chute 31, which is formed on the inner walls of both sides of the device body 1. A sieve plate 32 is slidably connected to the inner wall of the chute 31. A connecting plate 33 is fixedly connected to the end of the sieve plate 32. A connecting block 36 is fixedly connected to the end of the connecting plate 33. The connecting block 36 passes through the end of the device body 1 away from the mounting member 21. A second motor 34 is fixedly connected to the end of the device body 1 away from the mounting member 21 through a support frame. A convex shaft 35 is fixedly connected to the output end of the second motor 34. One end of a mounting plate 37 is hinged to the outer surface of the convex shaft 35. The other end of the mounting plate 37 is hinged to the inner wall of the connecting block 36. The second motor 34 is a double-headed motor, and the size of the sieve plate 32 is smaller than that of the device body. The internal dimensions of the device body 1 are controlled within the diameter range of the screen holes of the screen plate 32. The shape of the screen plate 32 is set to arc. The second motor 34 drives the cam shaft 35 to rotate, which enables the mounting plate 37 and the connecting block 36 hinged to the cam shaft 35 to convert the rotational force into the lateral movement force. The laterally moving connecting block 36 will drive the connecting plate 33 and the screen plate 32 to slide laterally inside the slide groove 31. At this time, because the size of the screen plate 32 is smaller than the internal size of the device body 1, and the difference between the screen plate 32 and the internal size of the device body 1 is controlled within the diameter range of the screen holes of the screen plate 32, even if the screen plate 32 can slide inside the device body 1, it will not allow unqualified feed to leak through the gaps created by the sliding.

[0029] In this embodiment of the present invention, a rotating gear 4 is fixedly connected to the output end of the second motor 34 away from the convex shaft 35. A fixed gear 41 meshes with the outer wall of the rotating gear 4. A second transmission belt 42 is driven to the outer surface of the fixed gear 41. A receiving shaft 43 is driven to the inside of the second transmission belt 42. A third transmission belt 44 is driven to the outer wall of the receiving shaft 43. A mounting rod 45 is driven to the third transmission belt 44. A mounting rod 45 is fixedly connected to the end of the mounting rod 45 near the device body 1. A mounting ring 46 is fixedly connected to the outer surface of the mounting rod 45. A baffle 47 is fixedly connected to the outer surface of the mounting ring 46. A feeding plate 48 is fixedly connected to the inner wall of the device body 1. The feeding plate 48 is configured to be lower near the two sides of the device body 1 and higher away from the two sides of the device body 1. A stop block 49 is fixedly connected to the bottom surface of the feeding plate 48. 9 The end near the baffle 47 is set as arc. The control console 5 is fixedly connected to the side wall of the device body 1. Because the second motor 34 is set as a bidirectional output motor, it can drive the output ends on both sides to rotate at the same time. The output end of the second motor 34 away from the cam shaft 35 rotates and drives the rotating gear 4 to rotate. This further causes the fixed gear 41 meshing with the outer wall of the rotating gear 4 to rotate. The power is transmitted to the receiving shaft 43 through the second transmission belt 42. The receiving shaft 43 transmits the power to the mounting rod 45 through the third transmission belt 44. This allows the mounting rod 45 to drive the mounting ring 46 and the baffle 47 to rotate in the space formed by the feeding plate 48 and the bottom surface of the device body 1. The rotating baffle 47 will periodically collide with the stop block 49 on the bottom surface of the feeding plate 48. The vibration generated by the collision can help the feed on the feeding plate 48 to be discharged through the discharge port 12 as soon as possible.

[0030] In this invention, during use, after the feed is fed into the feeding port 11, it is first processed by the crushing mechanism 2. The first motor 22 drives the fixed shaft 24 and the crushing roller 27 on it to rotate through the connecting gear 23, thus crushing the feed. At the same time, the first motor 22 drives the connecting shaft 26 and the fixed rod 28 to rotate through the first transmission belt 25. The fixed rod 28 transmits power to the connecting cylinder 210 through the spiral spring 29, thereby driving the flip plate 211 to rotate, turning the material over, and performing secondary crushing on unqualified materials. Subsequently, the feed that has undergone preliminary crushing falls onto the screen plate 32 of the screening mechanism 3, and the second motor 34 drives the cam shaft 35 to rotate. The mounting plate 37 and connecting block 36 drive the screen plate 32 to slide back and forth in the chute 31, which improves the screening efficiency of the screen plate 32 for materials. Fine materials that meet the requirements fall down, while coarse materials are pushed back by the flip plate 211 for re-crushing. At the same time, the other output end of the second motor 34 drives the mounting rod 45 and mounting ring 46 to rotate through the rotating gear 4, fixed gear 41, second transmission belt 42, receiving shaft 43 and third transmission belt 44, thereby driving the baffle 47 to rotate. In conjunction with the fixed discharge plate 48 and stop block 49, the discharge plate 48 can generate periodic vibration, which further promotes the discharge of qualified feed. The entire process is centrally controlled by the control console 5.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
