Description

Technical Field

[0001] This utility model relates to a pulverizing device, and more particularly to a high-efficiency pulverizing device for fish feed production, belonging to the field of fish feed production technology. Background Technology

[0002] Fish feed is specially designed for fish, and its main components include protein, fat, vitamins, and minerals, aiming to meet the nutritional needs of fish for growth and health. Depending on the raw materials and processing methods, fish feed can be divided into various types, such as pelleted feed, cake feed, grain feed, green fodder, bran feed, and protein feed.

[0003] Fish feed production requires the raw materials to be crushed and mixed to ensure uniformity and palatability. When raw materials with high moisture content are crushed into smaller fragments, these fragments tend to adhere together due to the high internal moisture content, forming large clumps. These clumps are difficult to pass through the pores of a screen, resulting in low screening efficiency. Furthermore, the clumps increase the difficulty of secondary crushing, leading to accelerated wear on the crusher. Therefore, a high-efficiency crushing device for fish feed production is proposed. Utility Model Content

[0004] In view of this, the present invention provides a high-efficiency pulverizing device for fish feed production, so as to solve or alleviate one of the technical problems existing in the prior art, and at least provide a beneficial option.

[0005] The technical solution of this utility model embodiment is implemented as follows: a high-efficiency pulverizing device for fish feed production includes a pulverizing component, and a screening component is provided at the bottom of the pulverizing component. The screening component includes a screening box, a support leg, a circulating air duct, a heater, a fan, a guide rod, a spring, a screening plate, and a vibration motor.

[0006] The bottom of the screening box is symmetrically and fixedly connected with support legs. The top of the screening box is connected to a circulating air duct, on which a heater and a fan are installed. A guide rod is slidably connected to the inner side wall of the screening box, and a spring is sleeved on the outer side wall of the guide rod. A screening plate is fixedly connected to the top of the guide rod, and a vibration motor is installed at the bottom of the screening plate. The vibration motor drives the screening plate to vibrate, causing the material to move along the screening plate. Through the operation of the heater and the fan, circulating hot air is sent into the screening box to dry the crushed material, preventing the material from clumping and making it difficult to pass through the screening plate, thus improving screening efficiency.

[0007] A further preferred embodiment: the bottom of the screening box is provided with a first discharge port.

[0008] A further preferred embodiment: a second discharge port is provided on one side of the screening box.

[0009] A further preferred embodiment: the pulverizing assembly includes a pulverizing chamber and a drive motor;

[0010] The front surface of the crushing chamber is symmetrically equipped with drive motors.

[0011] A further preferred embodiment: the inner sidewall of the crushing box is symmetrically rotatably connected with crushing rollers, and one end of the crushing rollers is fixedly connected to the output shaft of the drive motor.

[0012] A further preferred embodiment: the bottom of the crushing box is symmetrically and fixedly connected with support columns, and the support columns are fixedly connected to the top of the screening box.

[0013] A further preferred embodiment: the bottom of the crushing box is connected to a feed pipe, and one end of the feed pipe is connected to a screening box.

[0014] A further preferred embodiment: the surface of the screening plate is uniformly provided with through holes, and one end of the screening plate extends through the second discharge port to the outside of the screening box.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] I. This utility model uses a heater and a fan to send circulating hot air into the screening box. The circulating hot air dries the crushed material, preventing the material from clumping together and making it difficult to pass through the screening plate, thus improving screening efficiency. At the same time, the hot air reduces the moisture content of the material, so that larger particles can be crushed a second time.

[0017] II. This utility model uses a vibrating motor to drive the screening plate to vibrate, thereby screening materials of different particle sizes. This allows workers to concentrate on processing larger particles and improves the production efficiency of fish feed.

[0018] The above overview is for illustrative purposes only and is not intended to be limiting in any way.

The screening component 20 includes a screening box 21, a support leg 22, a circulating air duct 25, a heater 26, a fan 27, a guide rod 28, a spring 29, a screening plate 210, and a vibration motor 211.

[0028] The bottom of the screening box 21 is symmetrically and fixedly connected with support legs 22. The top of the screening box 21 is connected to a circulating air duct 25. A heater 26 and a fan 27 are installed on the circulating air duct 25. A guide rod 28 is slidably connected to the inner side wall of the screening box 21.

A vibration motor 211 is installed at the bottom of the screening plate 210. The vibration motor 211 drives the screening plate 210 to vibrate, causing the material to move along the screening plate 210. Through the operation of the heater 26 and the fan 27, circulating hot air is sent into the screening box 21. The circulating hot air dries the crushed material, preventing the material from clumping and making it difficult to pass through the screening plate 210, thereby improving the screening efficiency.

[0029] In this embodiment, specifically: the bottom of the screening box 21 is provided with a first discharge port 23, and materials of qualified size are discharged from the first discharge port 23.

[0030] In this embodiment, specifically: a second discharge port 24 is provided on one side of the screening box 21, and larger materials are sent out from the second discharge port 24.

[0031] In this embodiment, specifically: the crushing component 10 includes a crushing box 11 and a drive motor 12;

[0032] Two drive motors 12 are symmetrically mounted on the front surface of the crushing box 11. The two drive motors 12 work simultaneously, driving the two crushing rollers 13 to rotate synchronously in opposite directions.

[0033] In this embodiment, specifically: the inner sidewall of the crushing box 11 is symmetrically rotatably connected with crushing rollers 13, one end of the crushing rollers 13 is fixedly connected to the output shaft of the drive motor 12, and the crushing rollers 13 are driven to rotate by the drive motor 12, so that the raw materials are crushed by the two crushing rollers 13.

[0034] In this embodiment, specifically: support columns 14 are symmetrically and fixedly connected to the bottom of the crushing box 11. The support columns 14 are fixedly connected to the top of the screening box 21. The support columns 14 are used to support the crushing box 11 at the top and improve the stability of the crushing box 11 in the process of crushing materials.

[0035] In this embodiment, specifically: the bottom of the crushing box 11 is connected to the feed pipe 15, one end of the feed pipe 15 is connected to the screening box 21, and the crushed material is sent into the screening box 21 through the feed pipe 15.

[0037] In operation, the raw material is fed into the crushing box 11, and the crushing roller 13 is driven to rotate by the drive motor 12. The two crushing rollers 13 crush the raw material. After crushing, the material is fed into the screening box 21 through the feed pipe 15. The vibration motor 211 drives the screening plate 210 to vibrate, causing the material to move along the screening plate 210. The heater 26 and the fan 27 work to send circulating hot air into the screening box 21. The circulating hot air dries the crushed material, preventing it from clumping and making it difficult to pass through the screening plate 210, thus improving screening efficiency. At the same time, the hot air reduces the moisture content of the material, so that larger particles can be crushed again. The screened material is sent out through the first discharge port 23 and the second discharge port 24, so that the staff can centrally process the larger particles and improve the production efficiency of fish feed.
