Description

Technical Field

[0001] This utility model belongs to the field of feed production technology, and in particular relates to a uniform feeding device for a feed pellet mill cooler. Background Technology

[0002] The feed pellet mill cooler is a key piece of equipment following the pellet mill in the feed processing production line. Its core function is to quickly and evenly cool the hot feed pellets that have just been extruded from the pellet mill's ring die holes, which are in a high-temperature and high-humidity state, and reduce the moisture content to a safe storage level. It is a core link in ensuring the physical quality (hardness, powdering rate), chemical quality (nutritional stability), and storage safety (prevention of mold) of the pelleted feed. Its efficient and stable operation is directly related to the quality, safety, and production cost (energy consumption, loss) of the final feed product. After pelleting, the feed generally needs to be dispersed by a uniform feeding device to improve the cooling and drying effect and efficiency of the feed.

[0003] A search revealed CN218210558U, with an application date of September 13, 2022, which discloses a uniform feeding device for a feed pellet mill cooler. The device includes a feed cooler housing and a pellet mill body positioned above the housing. The top of the feed cooler housing is connected to the bottom of the pellet mill body via a feed pipe. This uniform feeding device uses a dual-head motor to drive a conical dispersing block, causing the feed to disperse and fall onto a vibrating disc. Simultaneously, the dual-head motor drives a transmission shaft, which in turn drives a horizontal shaft via upper and lower bevel gears, further rotating the disc. A pull rod and welding block work together to cause the vibrating disc to move rapidly up and down, vibrating the feed pellets on top. This effectively prevents feed from piling up, ensuring even distribution and preventing interference with cooling and drying, thus improving feed processing efficiency.

[0004] However, it still has the following drawbacks in practical use:

[0005] The existing feed pellet mill cooler's feeding device disperses the feed by driving a feeding mechanism, but this method is complex and costly.

[0006] 2. Existing feed pellet mill coolers use a power telescopic rod to adjust the height of the baffle to allow feed to fall. However, this method only covers a portion of the vibrating disc, preventing feed outside the baffle's coverage area from falling. Therefore, we provide a feed pellet mill cooler uniformization device to solve the aforementioned problem. Utility Model Content

[0007] The purpose of this utility model is to provide a feeding distribution device for a feed pellet mill cooler. By setting a feeding distribution component, the feeding distribution plate can vibrate up and down, and under the action of springs, it can buffer and protect the feeding distribution plate, preventing feed from accumulating on the surface of the feeding distribution plate, improving the cooling and drying efficiency and effect of the feed. Moreover, the structure is simple and low in cost. Furthermore, by using a closing component to push and adjust the two sides of the feeding distribution plate to tilt and open, the feed on the surface of the feeding distribution plate can fall down, achieving rapid and clean feed discharge, high efficiency, and good effect.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a material leveling device for a feed pellet mill cooler, including a material leveling barrel and a cold air fan installed on one side wall of it. Arc-shaped holes are opened on both sides of the front end face of the material leveling barrel, a material leveling component is installed inside the material leveling barrel, and a closing component is installed on the front end face of the material leveling barrel.

[0010] The material leveling assembly includes a bracket installed on the inner wall of the material leveling tank, and a housing fixed in the center of the bracket. A dual-head motor is installed inside the housing, and a conical block is installed on the top output shaft of the dual-head motor.

[0011] The closing assembly includes an electric push rod mounted on the top of the front face of the equalization tank, and a toothed plate mounted on the telescopic end of the electric push rod.

[0012] The present invention is further configured such that a feed pipe is provided at the center of the top of the uniform material barrel, and a discharge pipe is provided at the center of the bottom of the uniform material barrel.

[0013] The present invention is further configured such that the bottom output shaft of the dual-head motor is connected to the first rotating shaft via a coupling, a flat plate is installed at the bottom end of the first rotating shaft, and an active conical wheel is sleeved on the outer wall of the first rotating shaft.

[0014] The present invention is further configured such that a driven cone wheel is meshed with one side of the driving cone wheel, a second rotating shaft is fixed at the center of one side wall of the driven cone wheel, and the other end of the second rotating shaft passes through a bearing on the support plate and is connected to a cam.

[0015] The present invention is further configured such that the top of the support plate is fixed on the inner wall of the material leveling barrel, and a lifting frame is provided below the cam. Both ends of the lifting frame are fitted with material leveling plates via hinges.

[0016] The present invention is further configured such that the four corners of the lifting frame are slidably mounted on the outer wall of the I-shaped rod, a spring is sleeved on the lower part of the outer wall of the I-shaped rod, and the outer wall of the I-shaped rod is fixed on the inner wall of the uniform material bucket.

[0017] The present invention is further configured such that both ends of the toothed plate are meshed with toothed discs, a third rotating shaft is fixed at the center of the rear end face of the toothed discs, and the other end of the third rotating shaft is rotatably mounted on the outer wall of the uniform material barrel.

[0018] The present invention is further configured such that a connecting rod is fixedly provided on one side of the rear end face of the toothed disc, and the other end of the connecting rod passes through an arc-shaped hole and is fixedly connected to the adjacent uniform material plate.

[0019] This utility model has the following beneficial effects:

[0020] This invention features a material leveling component. A dual-head motor drives a cam and a flat material plate to rotate. The rotating cam repeatedly pushes the material leveling plate up and down, and the elasticity of the spring provides cushioning and protection for the plate, preventing feed from accumulating on its surface. This improves the cooling and drying efficiency and effectiveness of the feed. Furthermore, the structure is simple and low-cost, solving the problem that existing feed pellet mill coolers rely on a driving mechanism to disperse the feed, which is complex and costly.

[0021] This invention, by setting a closing component, can push and adjust the two sides of the equalizing plate to tilt and open under the action of an electric push rod, so that the feed on the surface of the equalizing plate falls down. This enables the feed to fall quickly, cleanly, efficiently, and effectively. It solves the problem that in the existing feed pellet mill cooler equalizing device, the height of the baffle is adjusted by an electric telescopic rod to make the feed fall. However, in this method, the baffle only covers a part of the vibrating plate, resulting in the feed outside the baffle coverage area not being able to fall down. Attached Figure Description

Detailed Implementation

[0030] 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 scope of protection of the present utility model. Example 1

[0031] Please see Figures 1 to 4 This utility model is a feeding device for a feed pellet mill cooler, including a feeding hopper 100 and a cooling fan 101 installed on one side wall of the feeding hopper 100. Arc-shaped holes 104 are provided on both sides of the front end face of the feeding hopper 100. A feeding assembly 200 is provided inside the feeding hopper 100. The feeding assembly 200 includes a bracket 201 installed on the inner wall of the feeding hopper 100 and a shell 201a fixed at the center of the inside of the bracket 201. A double-headed motor 202 is installed inside the shell 201a. A conical block 203 is installed on the top output shaft of the double-headed motor 202.

[0032] Specifically, a feed pipe 102 is provided at the top center of the material leveling hopper 100, and a discharge pipe 103 is provided at the bottom center of the material leveling hopper 100; the bottom output shaft of the dual-head motor 202 is connected to the first rotating shaft 204 via a coupling, a flat plate 204b is installed at the bottom end of the first rotating shaft 204, and a driving conical wheel 204a is sleeved on the outer wall of the first rotating shaft 204; a driven conical wheel 205a is meshed with one side of the driving conical wheel 204a, and a second rotating shaft 205 is fixed at the center of one side wall of the driven conical wheel 205a. The other end of the second rotating shaft 205 passes through the bearing on the support plate 206 and is connected to the cam 207; the top of the support plate 206 is fixed on the inner wall of the material equalization tank 100, and a lifting frame 208 is provided below the cam 207. Both ends of the lifting frame 208 are fitted with material equalization plates 209 via hinges; the four corners of the lifting frame 208 are slidably installed on the outer wall of the I-shaped rod 2010, and a spring 2011 is sleeved on the lower part of the outer wall of the I-shaped rod 2010. The outer wall of the I-shaped rod 2010 is fixed on the inner wall of the material equalization tank 100.

[0033] Furthermore, the air cooler 101 is existing technology and will not be described in detail here. The inner wall of the arc-shaped hole 104 is provided with an elastic sealing cloth to prevent feed leakage or dust from scattering during the falling process. The outer shell 201a protects the dual-head motor 202. The conical block 203 can disperse the falling feed. The bottom of the flat material plate 204b is a certain distance from the surface of the uniform material plate 209 to avoid squeezing the feed on the surface of the uniform material plate 209 and causing feed breakage. The rotation of the cam 207 can continuously push the lifting frame 208 back and forth. The I-shaped rod 2010 guides and limits the lifting frame 208. Under the elastic action of the spring 2011, it can automatically lift the lifting frame 208 after it falls.

[0034] The operation process of this embodiment is as follows: After pelleting, the feed enters the equalization tank 100 through the feed pipe 102. At this time, the dual-head motor 202 is started. The top output shaft of the dual-head motor 202 rotates, driving the cone block 203 to rotate, thereby spreading the falling feed onto the surface of the equalization plate 209. At the same time, the bottom output shaft of the dual-head motor 202 rotates, driving the first rotating shaft 204 to rotate through the coupling. The rotation of the first rotating shaft 204 will drive the driving cone wheel 204a and the flat plate 204b to rotate synchronously. The driving cone wheel 204a meshes with the outer wall of the driven cone wheel 205a, so the rotation of the driving cone wheel 204a will drive the... The driven cone wheel 205a rotates synchronously, which drives the second rotating shaft 205 and the cam 207 to rotate. The rotating cam 207 can cyclically apply force to the lifting frame 208, causing it to move up and down. During the movement, the lifting frame 208 slides along the outer wall of the I-shaped rod 2010 and squeezes the spring 2011, which plays a role in buffering and protection, and also shakes the feed on the surface of the equalizing plate 209 to disperse. At the same time, the rotating flat plate 204b can flatten the feed on the surface of the equalizing plate 209, further preventing the feed from accumulating on the surface of the equalizing plate 209, and improving the cooling and drying efficiency and effect of the feed. Example 2

[0035] Please see Figure 1 and Figure 5 Based on Embodiment 1, unlike the first embodiment, a closing component 300 is provided. The closing component 300 includes an electric push rod 301 installed on the top of the front end face of the feeding hopper 100, and a toothed plate 302 installed on the telescopic end of the electric push rod 301. This solves the problem that in the existing feeding hopper cooler, the feeding device adjusts the height of the baffle by the electric telescopic rod to make the feed fall. However, in this way, the baffle only covers part of the vibrating plate, resulting in the feed outside the baffle coverage area not being able to fall.

[0036] Specifically, both ends of the toothed plate 302 are meshed with toothed discs 303. A third rotating shaft 304 is fixed at the center of the rear end face of the toothed disc 303. The other end of the third rotating shaft 304 is rotatably mounted on the outer wall of the uniform material barrel 100. A connecting rod 303a is fixed on one side of the rear end face of the toothed disc 303. The other end of the connecting rod 303a passes through the arc-shaped hole 104 and is fixedly connected to the adjacent uniform material plate 209.

[0037] Furthermore, the toothed plate 302 meshes with the toothed discs 303 at both ends, playing a transmission role. The toothed discs 303 can rotate around the third rotating shaft 304 as the center. The connecting rod 303a connects the toothed discs 303 and the uniform plate 209, playing a connecting transmission role.

[0038] The operation process of this embodiment is as follows: After the feed on the surface of the equalizing plate 209 has cooled and dried, the electric push rod 301 is activated. The telescopic end of the electric push rod 301 extends and pushes the toothed plate 302 down. The toothed plate 302 meshes with the toothed discs 303 at both ends. Therefore, during the descent of the toothed plate 302, it will drive the toothed discs 303 at both ends to rotate around the third rotating shaft 304. The inner wall of the toothed disc 303 is connected to the equalizing plate 209 of the same plate through the connecting rod 303a. Therefore, when the toothed disc 303 rotates, it will drive the equalizing plates 209 at both ends to tilt and open through the connecting rod 303a. At this time, the feed on the surface of the equalizing plate 209 will fall and then be discharged through the discharge pipe 103. This can achieve rapid falling of feed, clean discharge, high efficiency, and good effect.
