Description

Technical Field

[0001] This utility model relates to the field of concentrated feed production technology, and in particular to a pulverizing device for concentrated feed production. Background Technology

[0002] Concentrated feed production refers to the process of mixing raw materials such as protein feed (e.g., fishmeal, soybean meal), mineral feed (e.g., bone meal, limestone powder), and additive premixes in a certain proportion to produce semi-finished feed. This type of feed has a high protein content and comprehensive nutritional components, and can be used as a component of complete feed.

[0003] Chinese patent CN210787541U discloses a practical and highly concentrated feed production equipment. The working principle of the equipment is as follows: when in use, the motor and the drive motor work simultaneously. The motor drives the crushing roller to crush the raw materials. The crushed powder falls into the powder screen through the powder outlet for sieving. Then the powder is conveyed out from the powder conveyor plate.

[0004] The shortcomings of the existing technical solutions are as follows: the crushed material undergoes a screening process to separate out the fine particles that meet the requirements. However, this process often screens out many larger particles, which are too large to participate in subsequent mixing processes. These particles must be manually or otherwise returned to the crushing device for further crushing. This approach is not only inefficient but also easily hinders the normal feeding of other qualified materials, adversely affecting the smoothness and efficiency of the entire production line. Utility Model Content

[0005] This utility model provides a pulverizing device for concentrated feed production, which can solve the problem in the existing concentrated feed pulverizing device that many large material particles screened out can only be manually or otherwise sent back to the pulverizing device for further pulverization, which is not only inefficient, but also easily hinders the normal feeding of other materials that have met the requirements.

[0006] A pulverizing device for concentrated feed production includes a shell, a feed inlet on the front side of the shell, a sealing cap on the feed inlet, a pulverizing cylinder rotatably mounted on the inner side of the shell, an opening at one end of the pulverizing cylinder aligned with the feed inlet, and a sealing cap at the other end, sieve holes on the side of the pulverizing cylinder, a pulverizing component rotatably mounted inside the pulverizing cylinder for pulverizing materials, a drive mechanism on the shell for driving the pulverizing component and the pulverizing cylinder to rotate in opposite directions, and a receiving chamber at the bottom of the inner shell.

[0007] As a further solution of the utility model: The crushing component includes mounting shafts rotatably connected to both ends of the crushing cylinder. A plurality of groups of blades for chopping materials are fixedly arranged at equal intervals on the side surfaces of the mounting shafts. A flow guide plate for guiding the materials to the blades is fixedly arranged around the inner wall of the crushing cylinder.

[0008] As a further solution of the utility model: The flow guide plate is arranged in a "human" shape. Each group of flow guide plates is located between two adjacent groups of blades. The opening direction of the flow guide plate is aligned with the cutting direction of the matching blade.

[0009] As a further solution of the utility model: The driving mechanism includes a motor fixedly arranged at the rear side of the housing. The output end of the motor is fixedly connected with a transmission shaft. The transmission shaft is coaxially and cooperatively connected with the mounting shaft.

[0010] As a further solution of the utility model: A surrounding wheel is coaxially and fixedly connected to the outside of the crushing cylinder. A rotating shaft is rotatably arranged inside the housing. A driving wheel cooperating with the surrounding wheel is coaxially and fixedly connected to the rotating shaft. Transmission wheels are coaxially and fixedly connected to both the rotating shaft and the transmission shaft. Transmission belts are cooperatively arranged on both groups of transmission wheels.

[0011] As a further solution of the utility model: An outlet is opened on one side of the material receiving cavity. A blocking component for blocking the outlet is arranged on the outlet.

[0012] As a further solution of the utility model: A material guiding plate inclined towards the outlet is arranged at the bottom of the material receiving cavity.

[0013] As a further solution of the utility model: A sliding opening is opened on one side of the outlet. The sliding opening is communicated with one side of the outlet. The blocking component includes a sliding plate slidably arranged inside the sliding opening for blocking the outlet.

[0014] As a further solution of the utility model: A positioning plate rotatably connected to the crushing cylinder is fixedly arranged inside the housing. One end of the crushing cylinder close to the outlet is rotatably connected to the outlet.

[0015] As a further solution of the utility model: The blocking cover is threadedly connected to the outlet.

[0016] The beneficial effects of the utility model:

[0017] 1. In use, this utility model utilizes a motor to drive a transmission shaft to rotate, which in turn drives a mounting shaft to rotate. The mounting shaft then moves the blades. Simultaneously, the transmission shaft, via a transmission belt, drives a rotating shaft to rotate, which in turn drives a drive wheel to rotate. This drive wheel then drives a surrounding wheel to rotate in the opposite direction, which in turn drives the crushing cylinder to rotate. This achieves the effect of relative rotation between the crushing cylinder and the transmission shaft, and relative movement between the blades and the crushing cylinder. This increases the relative speed between the blades and the guide plate, as well as the cutting efficiency, and increases the likelihood of large pieces of material coming into contact with the blades. When the crushing cylinder tumbles the material, the material is guided to the vicinity of the blades on both sides by the guide plate, thereby improving the cutting and crushing effect of the blades on the material.

[0018] 2. When this utility model is in use, because the radius of the surrounding wheel is much larger than the radius of the driving wheel, the rotation speed of the surrounding wheel is much smaller than the rotation speed of the driving wheel. This ensures that when the blade has a high cutting speed, the crushing cylinder has a low rotation speed, thus avoiding the situation where the centripetal force on the material is too large, causing the material to stick to the inner surface of the crushing cylinder and affecting the crushing effect.

[0025] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0026] like Figures 1 to 4 As shown in the figure, the present invention provides a pulverizing device for concentrated feed production, including a shell 1. A feed inlet 101 is provided on the front side of the shell 1, and a sealing cap 108 is fitted onto the feed inlet 101. The sealing cap 108 is threadedly connected to the discharge outlet 103 to ensure the stability of the sealing cap 108 after it is fixed. A pulverizing cylinder 2 is laterally rotatable inside the shell 1, such as... Figure 2 As shown, the crushing cylinder 2 has an opening at one end, which is aligned with the feed inlet 101, and the other end is sealed. The crushing cylinder 2 has a screen hole 201 on its side to ensure that the material inside can only fall out of the screen hole 201.

[0027] The crushing cylinder 2 is equipped with a crushing component 3 for crushing materials. The crushing component 3 includes a mounting shaft 301 that is rotatably connected to both ends of the crushing cylinder 2. Multiple sets of blades 302 for cutting materials are fixedly arranged at equal intervals on the side of the mounting shaft 301. The mounting shaft 301 drives the blades 302 to rotate, thereby achieving the cutting and crushing of materials.

[0028] The outer casing 1 is equipped with a drive mechanism 4 for driving the mounting shaft 301 and the crushing cylinder 2 to rotate in opposite directions. The rotation of the crushing cylinder 2 agitates the material, causing collisions between materials and increasing the likelihood of each part of the material contacting the blade 302. A guide plate 202 is fixedly arranged around the inner wall of the crushing cylinder 2 to guide the material to the blade 302. The guide plate 202 is arranged in a "V" shape. Figure 3 As shown, each set of guide plates 202 is located between two adjacent sets of blades 302, and the opening direction of the guide plate 202 is aligned with the cutting direction of the mating blade 302. When the crushing drum 2 tumbles the material, the material is guided to the vicinity of the blades 302 on both sides under the action of the guide plates 202, and the blades 302 move relative to the crushing drum 2, thereby improving the relative speed between the blades 302 and the guide plates 202 and the cutting efficiency.

[0029] The drive mechanism 4 includes a motor 401 fixedly mounted on the rear side of the housing 1. A transmission shaft 402 is fixedly connected to the output end of the motor 401, and the transmission shaft 402 is coaxially connected to the mounting shaft 301. The motor 401 drives the transmission shaft 402 to rotate, which in turn drives the mounting shaft 301 to rotate. The mounting shaft 301 then drives the blade 302 to move, thereby achieving material cutting. A circular wheel 406 is coaxially fixedly connected to the outer side of the crushing cylinder 2. (Please refer to...) Figure 2 and Figure 4Upon observation, a rotating shaft 404 is rotatably mounted inside the outer casing 1. A drive wheel 405, which cooperates with the surrounding wheel 406, is coaxially fixedly connected to the rotating shaft 404. Both the rotating shaft 404 and the drive shaft 402 are coaxially fixedly connected to drive wheels, and both sets of drive wheels are fitted with drive belts 403. The motor 401 drives the drive shaft 402 to rotate, and the drive shaft 402 drives the rotating shaft 404 to rotate via the drive belt 403, which in turn drives the drive wheel 405 to rotate. The drive wheel 405 drives the surrounding wheel 406 to rotate in the opposite direction, and the surrounding wheel 406 drives the crushing cylinder 2 to rotate, achieving the effect of relative rotation between the crushing cylinder 2 and the drive shaft 402.

[0030] It is important to note that, such as Figure 4 As shown, the radius of the surrounding wheel 406 is much larger than the radius of the driving wheel 405, which makes the rotation speed of the surrounding wheel 406 much smaller than the rotation speed of the driving wheel 405. This ensures that when the blade 302 has a high cutting speed, the crushing cylinder 2 has a low rotation speed, thus avoiding the situation where the centripetal force on the material is too large, causing the material to adhere to the inner surface of the crushing cylinder 2 and affecting the crushing effect.

[0031] The inner bottom of the outer casing 1 has a receiving chamber 102, and a discharge port 103 is opened on one side of the receiving chamber 102. A sealing component for blocking the discharge port 103 is provided on the discharge port 103. A sliding port 104 is opened on one side of the discharge port 103, and the sliding port 104 is connected to the discharge port 103. The sealing component includes a sliding plate 105 slidably disposed inside the sliding port 104 for blocking the discharge port 103. A guide plate 107 is provided at the bottom of the receiving chamber 102, which is inclined towards the discharge port 103. The guide plate 107 is used to guide the filtered material. The filtered material will concentrate above the guide plate 107 and approach the discharge port 103 under the vibration of the frame itself. After crushing, the sliding plate 105 is pulled out, thereby exposing the material inside the discharge port 103. The material is then scraped out with a tool, thus completing the discharge process.

[0032] A positioning plate 106 is fixedly installed inside the outer casing 1 and is rotatably connected to the crushing cylinder 2. The end of the crushing cylinder 2 near the discharge port 103 is rotatably connected to the discharge port 103. The positioning plate 106 and the discharge port 103 are used to position the crushing cylinder 2 and ensure the stability of the crushing cylinder 2 during rotation.

[0033] Working principle: During use, material is fed into the crushing cylinder 2 through the feed inlet 101. Then, the sealing cap 108 is screwed into the feed inlet 101, thereby blocking one end of the crushing cylinder 2 and preventing material leakage. The motor 401 drives the drive shaft 402 to rotate, which in turn drives the mounting shaft 301 to rotate. The mounting shaft 301 drives the blade 302 to move. At the same time, the drive shaft 402 drives the rotating shaft 404 to rotate through the drive belt 403, which in turn drives the drive wheel 405 to rotate. The drive wheel 405 drives the surrounding wheel 406 to rotate in the opposite direction. The surrounding wheel 406 drives the crushing cylinder 2 to rotate, achieving the effect of relative rotation between the crushing cylinder 2 and the drive shaft 402. The blade 302 moves relative to the crushing cylinder 2, thereby increasing the relative speed between the blade 302 and the guide plate 202 and the cutting efficiency, and increasing the possibility of large pieces of material coming into contact with the blade 302. When the crushing drum 2 tumbles the material, the material will be guided to the vicinity of the blades 302 on both sides under the action of the guide plate 202, thereby improving the cutting and crushing effect of the blades 302 on the material;

[0034] Because the radius of the surrounding wheel 406 is much larger than the radius of the driving wheel 405, the rotation speed of the surrounding wheel 406 is much smaller than the rotation speed of the driving wheel 405. This ensures that when the blade 302 has a high cutting speed, the crushing cylinder 2 has a low rotation speed, thus avoiding the situation where the centripetal force on the material is too large, causing the material to adhere to the inner surface of the crushing cylinder 2 and affecting the crushing effect.

[0035] The filtered material will be concentrated above the guide plate 107 and approach the discharge port 103 under the vibration of the frame itself. After crushing, the slide plate 105 is pulled out, thus exposing the material inside the discharge port 103. The material can be scraped out with tools or gradually output by relying on the vibration of the machine body.

[0036] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
