Description

Technical Field

[0001] This utility model relates to the field of feed production and conveying technology, specifically to a high-efficiency crushing device for raw materials used in livestock feed production. Background Technology

[0002] In livestock farming, to provide cattle, sheep and other livestock with nutritionally complete feed, it is usually necessary to fully crush and mix various raw materials, such as soybeans, corn, amino acids and grains, to formulate scientifically nutritious feed. Therefore, feed crushing equipment is needed. Most of them crush raw materials by cutting, crushing or grinding. However, the position of the raw materials is always relatively fixed, and the crushing is not sufficient. Moreover, the fine particles produced by crushing are easy to float and overflow from the feed inlet, polluting the environment. Some raw materials contain moisture, which is easy to stick to the inner wall after crushing and grinding, resulting in waste of raw materials.

[0003] A high-efficiency crushing device for livestock feed production is disclosed in CN216678497U. The device uses a stirring shovel to lift the raw materials and two sets of oppositely rotating cutters to fully crush them. It has high crushing efficiency and better effect. The raw material powder will not be thrown up or overflow, avoiding environmental pollution. The dried raw material powder will not stick to the inner wall, avoiding waste, and will not stick to the cutters, affecting cutting. The raw material is also easy to remove. The entire device has high crushing efficiency and can be widely used in the crushing of various raw materials, with broad industrialization prospects.

[0004] However, the device does not differentiate between the pulverized raw materials, resulting in incompletely pulverized materials being mixed with properly pulverized materials, which affects subsequent feed production processes. Summary of the Invention

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: Example 1

[0024] A high-efficiency grinding device for livestock feed production includes a grinding chamber 1 and a top cover 2 bolted to the top surface of the grinding chamber 1. The top cover 2 is designed to prevent material from splashing or generating dust during transportation. A feed inlet is provided through the top surface of the top cover 2, and a feed hopper 201 is fixedly connected to the feed inlet. The feed hopper 201 can better transport materials into the interior of the grinding chamber 1. A fixed platform 101 is fixedly connected to the outer surface of the grinding chamber 1. A grinding chamber groove is provided through the top surface of the fixed platform 101. The inner wall of the grinding chamber groove of the fixed platform 101 is fixedly connected to the bottom of the outer wall of the grinding chamber 1. Four support legs 102 are fixedly connected to the bottom surface of the fixed platform 101, and anti-slip bases 103 are fixedly connected to the bottom surface of the support legs 102. The anti-slip bases 103 can further prevent the motor 305 and the vibration motor 404 from shifting during operation. A crushing device is provided on the inner wall of the grinding chamber 1, and a screening device is fixedly connected to the bottom surface of the grinding chamber 1.

[0025] The grinding device includes a grinding rod 301, a transmission roller 302, a connecting bearing 303, a rotating shaft 304, and a motor 305. The motor 305 is fixedly connected to the top surface of the fixed platform 101. The motor 305 is an SM3L-062A1NDV AC servo motor. The rotating shaft 304 is fixedly connected to the output port of the motor 305. The connecting bearing 303 is fixedly connected to the inner wall of the grinding chamber 1. The transmission roller 302 is fixedly connected to the outer surface of the rotating shaft 304. The grinding rod 301 is fixedly connected to the outer surface of the transmission roller 302. The grinding rod 301 is densely arranged on the outer surface of the transmission roller 302. The grinding rod 301 can grind the raw materials, allowing the materials to be restored during the conveying process to ensure the originality and stability of the quality, so as to facilitate the use of subsequent feed production processes and provide quality assurance for the raw materials.

[0026] The internal structure of the crushing device consists of two parts, and the working directions of the two crushing devices are opposite. The crushing rod 301 can more effectively crush the material. There are four connecting bearings 303, which are respectively fixedly connected to both sides of the inner wall of the crushing chamber 1. The transmission roller 302 is rotatably connected to the inner wall of the connecting bearing 303. The transmission roller 302 is rotatably connected to the inner wall of the crushing chamber 1 through the connecting bearing 303.

[0027] Working principle: When using this utility model, the material is fed into the crushing device through the feed hopper 201 on the top cover 2. The motor 305 drives the rotating shaft 304 to rotate, and under the influence of the connecting bearing 303, the transmission roller 302, which is tightly connected to the rotating shaft 304, starts to rotate inside the crushing chamber 1. The crushing rod 301 on the surface of the transmission roller 302 starts to work to rotate and crush the material. At the same time, the two crushing devices work in opposite directions to strengthen the crushing of the material and better prevent the formation of lumps that may affect subsequent processing. Example 2

[0028] Based on Embodiment 1, a high-efficiency crushing device for livestock feed production raw materials is provided. The screening device is used to screen materials with large particles or lumps that do not meet the requirements for subsequent processing, especially powdery raw materials or impurities in the materials. The screening device includes a vibrating screen shell 401, a vibrating screen frame 402, a screen 403, a vibrating motor 404, a material screening port 405, and a feeding port 406. The vibrating screen shell 401 is fixedly connected to the bottom surface of the crushing chamber 1, the vibrating screen frame 402 is fixedly connected to the inner wall of the vibrating screen shell 401, and the screen 403 is snapped into the inner wall of the vibrating screen frame 402. The screen 403 can be replaced according to different needs.

[0029] The vibrating motor 404 is fixedly connected to the bottom surface of the vibrating screen frame 402. The vibrating motor vibrates the screen to perform secondary optimization treatment on the crushed material. The screening material port 405 is fixedly connected to the side of the vibrating screen frame 402 and is connected through the side of the vibrating screen housing 401. Raw materials or impurities that do not meet the requirements and are not conducive to subsequent processing are discharged from the separate screening material port 405. The conveying port 406 is fixedly connected to the bottom surface of the vibrating screen housing 401. Materials that meet the requirements of the next process are conveyed to the next process through the conveying port 406.

[0030] Working principle: When this utility model is in use, the crushed material falls into the screening device. The vibrating screen frame 402 is affected by the vibrating motor 404, which causes the screen 403 to vibrate and screen. During the screening process, lumps or other impurities larger than the aperture of the screen 403 are discharged from the screening material outlet 405. Materials that meet the requirements are output to the feed production next process device through the inclined conveying outlet 406.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
