Abstract
Description
Technical Field
[0001] This application relates to the field of feed processing technology, and in particular to a feed secondary grinding processing apparatus. Background Technology
[0002] In the livestock industry, the food used to feed livestock such as cattle, sheep, chickens, and ducks is called feed. The formula of feed varies depending on the animal being fed. Traditional cattle and sheep feed is mostly made from raw materials such as corn, soybeans, and grains, combined with appropriate additives. High-quality feed can significantly improve the quality of livestock.
[0003] In feed processing, the collected raw materials need to be crushed before further processing. Existing feed crushing equipment generally involves feeding the feed into a crushing chamber and crushing it using multiple sets of crushing rollers. However, when a large amount of feed is crushed simultaneously, it is easy to cause uneven crushing. In the secondary crushing operation, all the crushed feed is usually crushed a second time, resulting in a large amount of feed in the crushing chamber. This also makes it difficult to screen and shred the crushed feed, which is inconvenient for users. Utility Model Content
[0004] This application provides a processing device for secondary grinding of feed, which solves the problem that existing feed grinding devices generally grind feed by putting it into a grinding box and grinding it through multiple sets of grinding rollers. However, when a large amount of feed is ground at the same time, the feed is easily ground unevenly. In the secondary grinding operation, all the ground feed is usually ground again, resulting in a large amount of feed in the grinding box, and it is also inconvenient to screen and grind the ground feed.
[0005] This application provides a processing device for secondary grinding of feed, including a first grinding box, a screening box installed at the bottom of the first grinding box, a screening plate arranged inside the screening box, an installation shaft hinged to the bottom of the screening plate, an installation spring connected to the top of the screening plate, a fixing plate installed at the bottom of the installation spring, a fixing plate connected to the bottom of the fixing plate, a screening motor installed at one end of the screening box, a rotating shaft installed at one end of the screening motor, a rotating disk installed on the outer wall of the rotating shaft, and a protrusion installed on the outer wall of the rotating disk.
[0006] Preferably, the top of the first crushing box is provided with a feed inlet.
[0007] Preferably, a drive motor is installed at one end of the first crushing box, a motor drive shaft is installed at one end of the drive motor, a first crushing roller is installed on the outer wall of the motor drive shaft, a transmission gear is installed at one end of the motor drive shaft, a driven gear meshes with one side of the transmission gear, a driven shaft is installed at one end of the driven gear, and a second crushing roller is installed on the outer wall of the driven shaft.
[0008] Preferably, the bottom of the first crushing box is provided with a discharge port.
[0009] Preferably, a limiting baffle is installed on one side of the screening box, and a discharge port is provided at the bottom end of the limiting baffle.
[0010] Preferably, a second crushing box is provided at the bottom of the discharge port, an electric motor is installed on one side of the second crushing box, a transmission wheel is installed at the end of the second crushing box away from the electric motor, a first driven wheel and a second driven wheel are respectively engaged on both sides of the transmission wheel, and a third crushing roller is installed inside the second crushing box.
[0011] Preferably, a collection box is provided at the bottom of the second crushing box.
[0012] Beneficial effects:
[0013] Considering that existing feed grinding devices generally involve feeding the feed into a grinding chamber and grinding it using multiple sets of grinding rollers, uneven grinding can easily occur when a large amount of feed is ground simultaneously. In the secondary grinding process, all the ground feed is usually ground a second time, resulting in a large amount of feed in the grinding chamber and making it inconvenient to screen and grind the ground feed.
[0014] The feed to be pulverized is poured into the feed inlet of the first pulverizing box. The drive motor is then turned on, causing the motor drive shaft to rotate the first pulverizing roller and the transmission gear synchronously. As the transmission gear rotates, it drives the driven gear on one side to rotate. The driven gear's rotation, in turn, drives the driven shaft and the second pulverizing roller to rotate synchronously. The feed is pulverized by the first and second pulverizing rollers. The pulverized feed falls through the discharge port onto the top of the screening plate inside the bottom screening box. At this point, the screening motor is turned on, causing the rotating shaft to drive the rotating disk and the protrusion to rotate. When the protrusion rotates to contact the screening plate, the spring force causes the top of the screening plate to swing upwards. When the protrusion disengages from the screening plate... When the screen plate is in operation, it will spring back to its original position, causing the top of the screen plate to swing up and down, thus screening the feed that has been screened in the first crushing box. The screened feed will fall directly into the collection box at the bottom, while larger feed will move downward with the screen plate until it falls into the discharge port. The incompletely crushed feed will be poured into the second crushing box through the discharge port. At this time, by turning on the motor, the transmission wheel, the first driven wheel, the second driven wheel and the three sets of third crushing rollers will be driven to rotate. The feed will be crushed a second time through the three sets of third crushing rollers. The crushed feed will fall into the collection box through the bottom of the second crushing box for convenient collection and processing by the user. Through secondary crushing and screening, the uniformity of feed crushing is increased.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0030] This utility model provides, for example Figure 1-5 The feed secondary grinding processing device shown includes a first grinding box 1, a screening box 11 installed at the bottom of the first grinding box 1, a screening plate 12 arranged inside the screening box 11, a mounting shaft 13 hinged to the bottom of the screening plate 12, a mounting spring 14 connected to the top of the screening plate 12, a fixing plate 15 installed at the bottom of the mounting spring 14, a fixing plate 16 connected to the bottom of the fixing plate 15, a screening motor 17 installed at one end of the screening box 11, a rotating shaft 18 installed at one end of the screening motor 17, a rotating disk 19 installed on the outer wall of the rotating shaft 18, and a protrusion 20 installed on the outer wall of the rotating disk 19.
[0031] In this process, the feed to be crushed is poured into the feed inlet 2 of the first crushing box 1. Then, the drive motor 3 is turned on, causing the motor drive shaft 4 to drive the first crushing roller 5 and the transmission gear 6 to rotate synchronously. When the transmission gear 6 rotates, it drives the driven gear 7 meshing on one side to rotate. When the driven gear 7 rotates, it drives the driven shaft 8 and the second crushing roller 9 to rotate synchronously. The feed is crushed by the first crushing roller 5 and the second crushing roller 9. The crushed feed falls through the discharge port 10 into the top of the screening plate 12 inside the bottom screening box 11. At this time, the screening motor 17 can be turned on, causing the rotating shaft 18 to drive the rotating disk 19 and the protrusion 20 to rotate. When the protrusion 20 rotates to contact the screening plate 12, under the elastic force of the installed spring 14, it will cause the top of the screening plate 12 to swing upward. When the protrusion 20 disengages from the screen, the top of the screen plate 12 will swing upward. When the feed is removed from the screening plate 12, the screening plate 12 will spring back to its original position, causing the top of the screening plate 12 to swing up and down, thereby screening the feed that has been screened in the first crushing box 1. The screened feed will fall directly into the collection box 29 at the bottom. Larger feed will move downward with the screening plate 12 until it falls into the discharge port 22. The feed that is not completely crushed will be poured into the second crushing box 23 through the discharge port 22. At this time, by turning on the motor 24, the transmission wheel 25, the first driven wheel 26, the second driven wheel 27 and the three sets of third crushing rollers 28 can be driven to rotate. The feed is crushed a second time through the three sets of third crushing rollers 28. The crushed feed will fall into the collection box 29 through the bottom of the second crushing box 23 for convenient collection and processing by the user. Through secondary crushing and screening, the uniformity of feed crushing is increased.
[0032] The top of the first crushing box 1 has a feed inlet 2.
[0033] In this process, the feed that needs to be crushed is poured into the feed inlet 2 on the first crushing box 1, and the feed is introduced into the interior of the first crushing box 1 through the feed inlet 2 for the first crushing operation.
[0034] A drive motor 3 is installed at one end of the first crushing box 1, a motor drive shaft 4 is installed at one end of the drive motor 3, a first crushing roller 5 is installed on the outer wall of the motor drive shaft 4, a transmission gear 6 is installed at one end of the motor drive shaft 4, a driven gear 7 is meshed on one side of the transmission gear 6, a driven shaft 8 is installed at one end of the driven gear 7, and a second crushing roller 9 is installed on the outer wall of the driven shaft 8.
[0035] In this process, by turning on the drive motor 3, the motor drive shaft 4 drives the first crushing roller 5 and the transmission gear 6 to rotate synchronously. When the transmission gear 6 rotates, it drives the driven gear 7 meshing on one side to rotate. When the driven gear 7 rotates, it drives the driven shaft 8 and the second crushing roller 9 to rotate synchronously. The feed is crushed by the first crushing roller 5 and the second crushing roller 9.
[0036] The bottom of the first crushing box 1 is provided with a discharge port 10.
[0037] The crushed feed will fall through the discharge port 10 into the top of the screening plate 12 inside the bottom screening box 11.
[0038] Preferably, a limiting baffle 21 is installed on one side of the screening box 11, and a discharge port 22 is provided at the bottom end of the limiting baffle 21.
[0039] Larger feed pieces will move downwards along the screening plate 12 until they fall into the discharge port 22. The feed pieces that are not fully crushed will be poured into the second crushing box 23 through the discharge port 22.
[0040] A second crushing box 23 is provided at the bottom of the discharge port 22. A motor 24 is installed on one side of the second crushing box 23. A transmission wheel 25 is installed at the end of the second crushing box 23 away from the motor 24. A first driven wheel 26 and a second driven wheel 27 are respectively engaged on both sides of the transmission wheel 25. A third crushing roller 28 is installed inside the second crushing box 23.
[0041] By turning on the motor 24, the transmission wheel 25, the first driven wheel 26, the second driven wheel 27 and the three sets of third crushing rollers 28 can be driven to rotate, and the feed is crushed in a secondary manner by the three sets of third crushing rollers 28.

[0043] The collection box 29 can collect the feed that has been crushed and sieved in the first stage and the feed that has been crushed in the second stage at the same time, which facilitates centralized processing.
[0044] Working principle: When using this feed secondary crushing processing device, the feed to be crushed is poured into the feed inlet 2 on the first crushing box 1, and then the drive motor 3 is turned on, so that the motor drive shaft 4 drives the first crushing roller 5 and the transmission gear 6 to rotate synchronously. When the transmission gear 6 rotates, it will drive the driven gear 7 meshing on one side to rotate. When the driven gear 7 rotates, it will drive the driven shaft 8 and the second crushing roller 9 to rotate synchronously. The feed is crushed by the first crushing roller 5 and the second crushing roller 9.
[0045] The crushed feed falls through the discharge port 10 into the top of the screening plate 12 inside the bottom screening box 11. At this time, the screening motor 17 can be turned on, so that the rotating shaft 18 drives the rotating disk 19 and the protrusion 20 to rotate. When the protrusion 20 rotates to contact the screening plate 12, under the elastic force of the installed spring 14, it will drive the top of the screening plate 12 to swing upward. When the protrusion 20 disengages from the screening plate 12, the screening plate 12 will spring back to its original position, so that the top of the screening plate 12 swings up and down, thereby performing screening operation on the feed screened by the first crushing box 1. The screened feed will fall directly into the bottom collection box 29.
[0046] Larger feed pieces will move downwards along the screening plate 12 until they fall into the discharge port 22. The incompletely crushed feed will be poured into the second crushing box 23 through the discharge port 22. At this time, by turning on the motor 24, the transmission wheel 25, the first driven wheel 26, the second driven wheel 27 and the three sets of third crushing rollers 28 will be driven to rotate. The feed will be crushed a second time through the three sets of third crushing rollers 28. The crushed feed will fall into the collection box 29 through the bottom of the second crushing box 23 for convenient collection and processing by the user. Through secondary crushing and screening, the uniformity of feed crushing is increased.
