AI Technical Summary
In existing feed processing pretreatment devices, the crushed raw materials are close to the conveyor belt when falling, and the blower is set on one side of the distribution chamber, resulting in insufficient screening. Raw materials with larger particle sizes can still fall to the conveyor belt, and the air separation effect is poor.
The system employs a vibrating screening mechanism and a pushing mechanism. Through the vibration of the screen plate and the oscillation of the pusher plate, the crushed raw materials are fully screened. The raw materials with smaller particle sizes fall directly into the collection box, while the raw materials with larger particle sizes are pushed out through the discharge port, which facilitates classified collection.
It improves screening efficiency, ensuring that smaller particles are effectively screened out and larger particles are pushed out, thus achieving more efficient material classification and collection.

Description
Technical Field
[0001] This utility model relates to the field of feed production technology, specifically a feed processing device. Background Technology
[0002] Feed is a general term for all food for artificially raised animals. Generally, feed mainly refers to the food for animals raised in agriculture or animal husbandry. Feed includes more than ten kinds of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. In the processing of animal feed, the raw materials need to undergo pre-treatment processes such as crushing and drying.
[0003] For example, according to authorization announcement number CN 212120122 U, a feed processing pretreatment device includes a crushing box and a feeding hopper located at the top of the crushing box. The crushing box is a rectangular box structure, and neither its upper nor lower ends are closed. The feeding hopper is a bucket-shaped structure, and its lower end is connected to the upper end of the crushing box. Roller shaft holes are opened on the front and rear side walls of the crushing box, and crushing roller shafts are rotatably installed in the roller shaft holes. There are two crushing roller shafts, and both roller shafts are driven by a motor. A material distribution chamber is provided at the lower end of the crushing box. By providing a material distribution chamber at the lower end of the crushing box and an air duct at the front end of the material distribution chamber, and by providing a blower at the front end of the air duct, the material with larger particle size is screened by air force after crushing, thereby preventing some larger particle size material from entering the lower production station and affecting the quality of the final product.
[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:
[0005] Although this feed processing pretreatment device can perform air separation on crushed raw materials, in use, because the crushed raw materials are close to the conveyor belt that receives them when they fall, and the blower is located on one side of the distribution chamber, there will be problems with insufficient screening. When the raw materials with larger particle sizes are close to the conveyor belt and are subjected to wind force, they can still fall to the top of the conveyor belt. At the same time, because the falling raw materials are mixed together and are relatively dense, the small-sized raw materials that are far away from the conveyor belt still have difficulty falling onto the conveyor belt, so the air separation effect is not good. Utility Model Content
[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a feed processing device that has the advantage of sufficient screening. It solves the problem that insufficient screening occurs because the crushed raw materials are close to the conveyor belt that receives them when they fall, and the blower is located on one side of the distribution chamber. When larger particles are close to the conveyor belt and are subjected to wind force, they can still fall to the top of the conveyor belt. At the same time, because the falling materials are mixed together and are relatively dense, smaller particles that are far from the conveyor belt still have difficulty falling onto the conveyor belt, resulting in poor air separation effect.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a feed processing device, comprising a frame, a feed hopper and a crushing roller, wherein the bottom of the feed hopper is fixedly connected to the top of the frame, the crushing roller is rotatably installed inside the feed hopper, and a vibration screening mechanism is provided inside the frame;
[0008] The vibrating screening mechanism includes a screen plate, the two sides of which are movably connected to the two sides of the inner wall of the frame. A transmission rod is provided at the bottom of the screen plate, and both ends of the transmission rod are rotatably connected to the two sides of the inner wall of the frame through bearings. A cam is fixedly connected to the surface of the transmission rod, and a convex plate is fixedly connected to the bottom of the screen plate. The number of cams and convex plates are the same and they correspond vertically. A pushing mechanism is provided on the right side of the screen plate.
[0009] As a preferred embodiment of this utility model, the pushing mechanism includes a mounting plate, a fixed column is fixedly connected to the top of the mounting plate, an arc-shaped plate is rotatably connected to the surface of the fixed column, a push plate is fixedly connected to the left side of the arc-shaped plate, and a discharge port is provided on both the front and rear sides of the frame.
[0010] As a preferred embodiment of this utility model, a motor is fixedly installed on the right side of the frame, a crank arm is fixedly connected to the output end of the motor, a shaft is fixedly connected to the other end of the crank arm, a guide groove is provided on the right side surface of the arc plate, and the surface of the shaft is movably connected to the inner wall of the guide groove.
[0011] As a preferred embodiment of this utility model, a support plate is provided at each of the four corners of the bottom of the screen plate. The outer side of the support plate is fixedly connected to the inner wall of the frame. A support spring is fixedly installed on the top of the support plate. The other end of the support spring is fixedly connected to the bottom of the screen plate. A movable rod installed at the bottom of the screen plate is provided inside the support spring. The other end of the movable rod passes through the support plate and extends to the bottom of the support plate.
[0012] As a preferred embodiment of this utility model, discharge hoppers are fixedly connected to both sides of the frame, and a collection box is fixedly installed at the bottom of the frame, with the collection box located directly below the sieve plate.
[0013] As a preferred embodiment of this invention, pulleys are fixedly installed on the surfaces of the crank arm and the transmission rod near the motor end, and the two pulleys are connected by belt drive.
[0014] As a preferred embodiment of this invention, a protective frame is fixedly connected to the right side of the top of the sieve plate, and the push plate is located inside the protective frame.
[0015] As a preferred embodiment of this utility model, a warm air blower is fixedly installed on the left side of the inner wall of the frame, and guide plates are fixedly connected to both sides of the inside of the feed hopper.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model, by setting up a vibration screening mechanism, allows the screen plate to screen the crushed raw material when it falls to the top of the screen plate, allowing the smaller particles to fall directly. At this time, the rotating transmission rod can drive the cam to rotate. When the cam contacts the convex plate and continues to rotate, it can drive the convex plate and the screen plate to rise. When the cam separates from the convex plate, the screen plate drops rapidly due to its own weight and the weight of the crushed raw material, thereby achieving a vibration screening effect on the crushed raw material and improving screening efficiency.
[0018] 2. By setting up a pushing mechanism, the arc plate can rotate on the surface of the fixed column. By rotating the arc plate, the push plate at the top of the screen plate can swing. At this time, the swing of the push plate can push out the remaining raw materials with larger particle size at the top of the screen plate through the discharge port, which is convenient for users to classify and collect.
[0019] 3. This utility model is equipped with a motor, a crank arm, a shaft, and a guide groove. The guide groove can limit the movement of the end of the shaft away from the motor. By starting the motor, the output end of the motor can drive the crank arm to rotate. The rotation of the crank arm can drive the shaft to move inside the guide groove. At this time, the movement of the shaft can drive the convex plate to swing on the surface of the fixed column. Attached Figure Description

[0025] 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.
[0026] like Figures 1 to 4 As shown, the feed processing device provided by this utility model includes a frame 1, a feed hopper 2 and a crushing roller 3. The bottom of the feed hopper 2 is fixedly connected to the top of the frame 1. The crushing roller 3 is rotatably installed inside the feed hopper 2. A vibration screening mechanism 4 is provided inside the frame 1.
[0027] The vibrating screening mechanism 4 includes a screen plate 41, the two sides of which are movably connected to the two sides of the inner wall of the frame 1. A transmission rod 42 is provided at the bottom of the screen plate 41. Both ends of the transmission rod 42 are rotatably connected to the two sides of the inner wall of the frame 1 through bearings. A cam 43 is fixedly connected to the surface of the transmission rod 42. A convex plate 44 is fixedly connected to the bottom of the screen plate 41. The number of cams 43 and convex plates 44 are the same and they correspond to each other vertically. A pushing mechanism 5 is provided on the right side of the screen plate 41.
[0028] The feed hopper 2 is equipped with two crushing rollers 3, both of which are driven by a motor 6, so that the two crushing rollers 3 rotate relative to each other, thereby crushing the raw materials entering the feed hopper 2.
[0029] Support plates 10 are provided at the four corners of the bottom of the screen plate 41. The outer side of the support plate 10 is fixedly connected to the inner wall of the frame 1. A support spring 11 is fixedly installed on the top of the support plate 10. The other end of the support spring 11 is fixedly connected to the bottom of the screen plate 41. A movable rod 12 installed at the bottom of the screen plate 41 is provided inside the support spring 11. The other end of the movable rod 12 passes through the support plate 10 and extends to the bottom of the support plate 10. The support plate 10 can support the screen plate 41 through the support spring 11. When the screen plate 41 vibrates, it can drive the movable rod 12 to move up and down. At this time, the movable rod 12 can prevent the screen plate 41 from shifting. At the same time, an L-shaped protective plate fixed to the bottom of the screen plate 41 is provided on the inner side of the support spring 11 to prevent the raw material from entering the inner side of the support spring 11 when it falls.
[0030] Thus, the pushing mechanism 5 includes a mounting plate 51, a fixed column 52 is fixedly connected to the top of the mounting plate 51, an arc plate 53 is rotatably connected to the surface of the fixed column 52, a push plate 54 is fixedly connected to the left side of the arc plate 53, and discharge ports 55 are opened on the front and rear sides of the frame 1.
[0031] Both sides of the frame 1 are fixedly connected to discharge hoppers 13, and a collection box 14 is fixedly installed at the bottom of the frame 1. The collection box 14 is located directly below the screen plate 41.
[0032] A motor 6 is fixedly installed on the right side of the frame 1. A crank arm 7 is fixedly connected to the output end of the motor 6. A shaft 8 is fixedly connected to the other end of the crank arm 7. A guide groove 9 is opened on the right side surface of the arc plate 53. The surface of the shaft 8 is movably connected to the inner wall of the guide groove 9.
[0033] The bottom of the push plate 54 does not contact the top of the screen plate 41 when the screen plate 41 is not vibrating. When the screen plate 41 vibrates, the swinging screen plate 41 can push the material on the top layer of the screen plate 41. When the push plate 54 contacts the top of the screen plate 41 and swings, it can push the remaining material on the top of the screen plate 41.
[0034] In addition, pulleys 15 are fixedly installed on the surfaces of the crank arm 7 and the transmission rod 42 near the motor 6. The two pulleys 15 are connected by belt drive, which makes it easy for the crank arm 7 to drive the transmission rod 42 to rotate synchronously, thus achieving a coaxial drive effect.
[0035] A protective frame 16 is fixedly connected to the right side of the top of the screen plate 41. The push plate 54 is located inside the protective frame 16. The protective frame 16 can limit the material on the top of the screen plate 41 to prevent the material from falling through the right side of the screen plate 41 when the push plate 54 swings.
[0036] Furthermore, a heater 17 is fixedly installed on the left side of the inner wall of the frame 1, and guide plates 18 are fixedly connected to both sides inside the feed hopper 2.
[0037] The working principle and usage process of this utility model are as follows: When in use, the motor 6 is started first, so that the output end of the motor 6 drives the crank arm 7 to rotate. The rotation of the crank arm 7 can drive the shaft 8 to move inside the guide groove 9. At this time, the movement of the shaft 8 can drive the convex plate 44 to swing on the surface of the fixed column 52, and then drive the push plate 54 to swing on the top of the screen plate 41. At the same time, the crank arm 7 and the transmission rod 42 are connected by belt drive. The rotation of the crank arm 7 can drive the transmission rod 42 and the cam 43 on its surface to rotate synchronously. When the cam 43 contacts the convex plate 44 and continues to rotate, it can drive the convex plate 44 and the screen plate 41 to rise. When the cam 43 separates from the convex plate 44, the screen plate 41 drops rapidly due to its own weight, thereby achieving the effect of vibration screening.
[0038] Users can put raw materials into the feed hopper 2 and use the guide plate 18 to guide the raw materials to the inside of the two relatively rotating crushing rollers 3, so that the crushing rollers 3 crush the raw materials. The crushed raw materials fall to the top of the screen plate 41. By starting the warm air blower 17, the crushed raw materials can be dried, so that the smaller particles fall directly into the collection box 14. At the same time, the vibrating screen plate 41 can improve the screening efficiency, and the swinging push plate 54 can push the remaining large particles of raw materials at the top of the screen plate 41 out from the two discharge ports 55. At this time, the discharge hopper 13 makes it convenient for users to collect the large particles of raw materials using a container.
