[0002] Lightweight feed is a specially designed feed in the animal husbandry industry. It mainly reduces the weight per unit volume by adjusting the formula and processing technology, while ensuring nutritional balance.

[0003] However, the dust removal equipment mentioned above removes dust through filter cylinders. But when too much dust adheres to the outer wall of the filter cylinder, it will lead to a decrease in filtration performance. Summary of the Invention

[0004] The purpose of this invention is to provide a dust removal device for lightweight feed to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a dust removal device for lightweight feed, including a dust collection box, a filter screen cylinder fixedly connected to the inner wall of the dust collection box, a fan fixedly connected to one end of the dust collection box, a backwash frame fixedly connected to the output end of the fan, a backwash pipe provided at the connection between the backwash frame and the dust collection box, an air outlet pipe fixedly connected to the outer wall of the backwash frame, a reciprocating push rod fixedly connected to the side wall of the backwash frame, a sliding block fixedly connected to the output end of the reciprocating push rod, a swing plate movably connected to the outer wall of the sliding block and spun to the side wall of the backwash frame, a switching plate hinged to the bottom end of the swing plate and a guide block fixedly connected to one end of the switching plate, and a backwash groove provided on the inner wall of the guide block;

[0006] A grinding assembly, located outside the dust collection box, is used to grind feed.

[0007] Based on the above structure, when the sliding block slides, it drives the switching plate to rotate through the swing plate, which in turn drives the backflushing groove inside the guide block to rotate synchronously. This allows the airflow generated by the fan to enter the dust collection box through the backflushing pipe, performing a backflushing cleaning operation on the filter cylinder and extending the service life of the filter cylinder.

[0008] Preferably, the switching plate forms a reciprocating swing structure between the swing plate and the recoil frame. In this embodiment, when the sliding block slides, the swing plate drives the switching plate to rotate, thereby realizing the control operation of the reciprocating swing of the switching plate.

[0009] Preferably, the swing center of the swing plate and the rotation center of the switching plate are located on the same vertical line. In this embodiment, this is beneficial to improving the stability of the swing of the switching plate.

[0010] Preferably, the backflushing groove is T-shaped. In this embodiment, the rotation of the switching plate drives the backflushing groove inside the guide block to rotate synchronously, thereby allowing the airflow generated by the fan to enter the dust collection box through the backflushing pipe to perform backflushing cleaning operation on the filter screen cylinder.

[0011] Preferably, the pulverizing component includes:

[0012] A crushing frame is provided outside the dust collection box. A motor is fixedly connected to the outer wall of the crushing frame. A rotating disk is fixedly connected to the output end of the motor. Crushing blades are hinged to the outer wall of the rotating disk. A crushing groove is fixedly connected to one side of the crushing blades on the inner wall of the crushing frame. A cyclone separator is fixedly connected to the output end of the crushing frame. A discharge port is fixedly connected to the bottom end of the cyclone separator. The top end of the cyclone separator is connected to one end of a filter screen cylinder via a pipe. In this embodiment, when the motor is working, it drives the rotating disk to rotate. The rotation of the rotating disk drives the three sets of crushing blades to rotate synchronously. The feed is crushed through the crushing groove. The crushed feed is sucked into the cyclone separator by the negative pressure generated by the fan. Light feed is discharged through the discharge port.

[0013] Preferably, the crushing blades are provided in three sets, and the three sets of crushing blades are distributed in a circle at equal angles about the center of the rotating disk. In this embodiment, by providing three sets of crushing blades, the rotation of the rotating disk drives the three sets of crushing blades to rotate synchronously, which helps to increase the contact area between the crushing blades and the feed.

[0014] Preferably, the grinding troughs are evenly distributed in a ring shape along the inner wall of the grinding frame. In this embodiment, this facilitates the rotation of the rotating disc to drive the three sets of grinding blades to rotate synchronously, thereby grinding the feed through the grinding troughs.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model is equipped with a crushing blade and a crushing trough. When the motor is working, it drives the rotating disk to rotate, thereby driving the three sets of crushing blades to rotate synchronously. The feed is crushed through the crushing trough. The crushed feed is sucked into the cyclone separator by the negative pressure generated by the fan, and the light feed is discharged through the discharge port.

[0017] 2. This utility model is equipped with a backflushing groove. When the sliding block slides, the switching plate is driven to rotate by the swing plate, which in turn drives the backflushing groove inside the guide block to rotate synchronously. This allows the airflow generated by the fan to enter the dust collection box through the backflushing pipe, and perform backflushing cleaning operation on the filter screen, thus extending the service life of the filter screen.

[0028] Based on the above structure, when the sliding block 8 slides, the switching plate 10 is driven to rotate by the swing plate 9, which in turn drives the backflushing groove 12 inside the guide block 11 to rotate synchronously. This allows the airflow generated by the fan 3 to enter the dust collection box 1 through the backflushing pipe 5, and perform backflushing cleaning operation on the filter cylinder 2, thereby extending the service life of the filter cylinder 2.

[0029] In one embodiment, the switching plate 10 forms a reciprocating swing structure with the swing plate 9 and the recoil frame 4.

[0030] In this embodiment, when the sliding block 8 slides, the switching plate 10 is rotated by the swing plate 9, thereby realizing the control operation of the reciprocating swing of the switching plate 10.

[0031] In one embodiment, the swing center of the swing plate 9 and the rotation center of the switching plate 10 are located on the same vertical line.

[0032] In this embodiment, it is beneficial to improve the stability of the swing of the switching plate 10.

[0033] In one embodiment, the backflush groove 12 is T-shaped.

[0034] In this embodiment, the rotation of the switching plate 10 drives the backflushing groove 12 inside the guide block 11 to rotate synchronously, thereby causing the airflow generated by the fan 3 to enter the dust collection box 1 through the backflushing pipe 5 to perform backflushing cleaning operation on the filter cylinder 2.

[0035] In one embodiment, the pulverizing component includes:

[0036] The crushing frame 13 is installed outside the dust collection box 1. The outer wall of the crushing frame 13 is fixedly connected to the motor 14.

The top end of the cyclone separator 18 is connected to one end of the filter screen cylinder 2 by a pipe.

[0037] In this embodiment, when the motor 14 is working, it drives the rotating disk 15 to rotate, thereby driving the three sets of crushing blades 16 to rotate synchronously. The feed is crushed through the crushing trough 17, and the crushed feed is sucked into the cyclone separator 18 by the negative pressure generated by the blower 3.

[0039] In this embodiment, by setting three sets of crushing blades 16, when the rotating disk 15 rotates, it drives the three sets of crushing blades 16 to rotate synchronously, thereby increasing the contact area between the crushing blades 16 and the feed.

[0040] In one embodiment, the pulverizing troughs 17 are uniformly distributed in a ring shape along the inner wall of the pulverizing frame 13.

[0041] In this embodiment, the rotating disc 15 facilitates the synchronous rotation of the three sets of crushing blades 16, and the feed can be crushed through the crushing trough 17.

[0042] When using this utility model, firstly, feed is added to the crushing frame 13. Then, when the motor 14 is working, it drives the rotating disk 15 to rotate, thereby driving the three sets of crushing blades 16 to rotate synchronously. The feed is crushed through the crushing trough 17. The crushed feed is then sucked into the cyclone separator 18 by the negative pressure generated by the blower 3, and the light feed is discharged through the discharge port 19.

[0043] Then, the dust in the cyclone separator 18 enters the dust collection box 1 and is filtered by the filter cylinder 2. Next, when the reciprocating push rod 7 is working, it drives the sliding block 8 to slide. When the sliding block 8 slides, it drives the switching plate 10 to rotate through the swing plate 9, thereby driving the backwash groove 12 inside the guide block 11 to rotate synchronously.
