[0007] The adjustable vibration cleaning mechanism includes a filter box, which is movably connected inside the machine body. A first limiting ring is fixedly connected to the top of the filter box, and a second limiting ring is fixedly connected to the bottom of the filter box. A filter screen is installed inside the filter box. Four sets of electric cylinders are installed between the filter box and the first limiting ring, and four sets of first springs are installed between the filter box and the second limiting ring.

[0008] As a further technical solution of the present invention, the four sets of electric cylinders are symmetrically distributed, and the four sets of the first springs are symmetrically distributed.

[0009] As a further technical solution of the present invention, the four sets of electric cylinders are electrically connected to the control seat, and the filter box can move up and down.

[0010] As a further technical solution of the present invention, the motor is electrically connected to the control seat, the feed port is connected to the inside of the machine body, and the outer side of the grinding roller is tightly fitted to the inner side of the grinding ring.

[0011] As a further technical solution of the present invention, a cleaning door is provided in the middle of the right side of the machine body, a support ring is movably connected to the bottom end of the grinding ring, a limit seat is fixedly connected to the front and rear ends of the support ring, movable ropes are provided on the front and rear sides of the machine body, a sliding groove is movably connected to the top of the limit seat, and a handle is installed at the front end of the cleaning door.

[0012] As a further technical solution of the present invention, the limiting seat can move up and down inside the movable rope under the action of the sliding groove, and the height of the grinding ring is less than the length of the cleaning door opening.

[0013] As a further technical solution of the present invention, four sets of fixing plates are fixedly connected to the bottom end of the base, a sleeve is provided below the fixing plate, two sets of bolts are installed between the fixing plate and the sleeve, and a second spring is installed at the bottom end of the fixing plate.

[0014] As a further technical solution of the present invention, the four sets of fixing plates are arranged symmetrically, and the second spring has a strong rebound force.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the pendulum mill not only realizes the quick cleaning of the filter screen, but also realizes the replacement and cleaning of the grinding ring, and also reduces the vibration amplitude of the machine;

[0016] (1) The machine is equipped with a first limiting ring, a second limiting ring, a filter box, a filter screen, an electric cylinder, and a first spring. During use, the material enters the machine body through the feed inlet, and the shovel rotates the material upward. The material is ground into powder between the grinding roller and the grinding ring. The fan is started by the control seat, and the fan sends the powder into the collection box through the suction cup and the collection pipe. The first limiting ring and the second limiting ring are set inside the machine body. The filter box is movably connected between the first limiting ring and the second limiting ring. The filter screen is installed inside the filter box, which can effectively perform preliminary screening of the powder. If the material is in contact with the filter screen for a long time, it will cause the filter screen to become blocked, reducing the filtration efficiency. By starting the electric cylinder, the electric cylinder extends downward and hits the filter box, causing the blockage in the filter screen to fall down, thereby cleaning the filter screen. Four sets of first springs are set between the filter box and the second limiting ring. The first springs can effectively return the filter box to the correct position, thereby extending the service life of the filter screen and improving the working efficiency.

[0017] (2) By setting up a support ring, a limit seat, a movable rope, a chute, a cleaning door and a handle, the grinding roller and grinding ring grind materials for a long time. At the junction of the grinding roller and the grinding ring, it is difficult to clean the grinding ring. The residue will affect the purity of the grinding powder when different materials are replaced. By opening the cleaning door with the handle and manually pulling the two sets of movable ropes, the movable ropes drive the limit seats on both sides of the support ring to slide upward in the chute, thereby realizing the upward sliding of the grinding ring. When the grinding ring reaches the cleaning door, the grinding ring can be taken out, thereby realizing the replacement and cleaning of the grinding ring.

[0018] (3) By setting a fixed plate, sleeve, bolt and second spring, the machine body has a certain vibration when working, especially when the electric cylinder hits the filter box. By installing four sets of fixed plates at the bottom of the base, and setting a sleeve below the four sets of fixed plates, a second spring is installed between the fixed plate and the sleeve. The second spring has a strong rebound force, which can effectively reduce the force in the vertical direction of the machine, thereby reducing the vibration amplitude of the machine.

[0028] Please see Figure 1-6 A pendulum mill also includes an adjustable vibration cleaning mechanism, which includes a filter box 19. The filter box 19 is movably connected to the inside of the machine body 1. A first limiting ring 17 is fixedly connected to the top of the filter box 19, and a second limiting ring 18 is fixedly connected to the bottom of the filter box 19. A filter screen 20 is installed inside the filter box 19. Four sets of electric cylinders 21 are installed between the filter box 19 and the first limiting ring 17, and four sets of first springs 22 are installed between the filter box 19 and the second limiting ring 18.

[0029] Four sets of electric cylinders 21 are symmetrically distributed, four sets of first springs 22 are symmetrically distributed, the four sets of electric cylinders 21 are electrically connected to the control seat 4, the filter box 19 can move up and down, the motor 6 is electrically connected to the control seat 4, the feed port 5 is connected to the inside of the machine body 1, and the outer side of the grinding roller 11 is tightly fitted to the inner side of the grinding ring 12.

[0030] Specifically, such as Figure 1 , Figure 4 and Figure 5As shown, during use, the material enters the machine body 1 through the feed port 5, and the shovel 10 rotates the material upward. The material is ground into powder between the grinding roller 11 and the grinding ring 12. The blower 13 is started by the control seat 4. The blower 13 sends the powder into the collection box 14 through the suction cup 16 and the collection pipe 15. A first limiting ring 17 and a second limiting ring 18 are set inside the machine body 1. A filter box 19 is movably connected between the first limiting ring 17 and the second limiting ring 18. A filter screen 20 is installed inside the filter box 19, which can effectively perform preliminary screening of the powder. If the material is in contact with the filter screen 20 for a long time, it will cause the filter screen 20 to become clogged and reduce the filtration efficiency. By starting the electric cylinder 21, the electric cylinder 21 extends downward and hits the filter box 19, causing the blockage in the filter screen 20 to fall down, thereby cleaning the filter screen 20. Four sets of first springs 22 are set between the filter box 19 and the second limiting ring 18. The first springs 22 can effectively return the filter box 19 to the correct position, thereby extending the service life of the filter screen 20 and improving the working efficiency.

[0031] A cleaning door 27 is provided in the middle of the right side of the machine body 1. A support ring 23 is movably connected to the bottom end of the grinding ring 12. The front and rear ends of the support ring 23 are fixedly connected to the limit seat 24. Movable ropes 25 are provided on the front and rear sides inside the machine body 1. A slide groove 26 is movably connected to the top of the limit seat 24. A handle 28 is installed at the front end of the cleaning door 27. The limit seat 24 can move up and down inside the movable rope 25 under the action of the slide groove 26. The height of the grinding ring 12 is less than the opening length of the cleaning door 27.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the grinding roller 11 and grinding ring 12 grind materials for a long time. At the junction of the grinding roller 11 and grinding ring 12, it is difficult to clean the grinding ring 12. The residue will affect the purity of the grinding powder when different materials are replaced. By opening the cleaning door 27 with the handle 28, the two sets of movable ropes 25 are manually pulled. The movable ropes 25 drive the limiting seats 24 on both sides of the support ring 23 to slide upward in the slide groove 26, thereby realizing the upward sliding of the grinding ring 12. When the grinding ring 12 reaches the cleaning door 27, the grinding ring 12 can be taken out, thereby realizing the replacement and cleaning of the grinding ring 12.

[0033] Four sets of fixing plates 29 are fixedly connected to the bottom of the base 2. A sleeve 30 is provided below the fixing plate 29. Two sets of bolts 31 are installed between the fixing plate 29 and the sleeve 30. A second spring 32 is installed at the bottom of the fixing plate 29. The four sets of fixing plates 29 are arranged symmetrically. The second spring 32 has a strong rebound force.

[0034] Specifically, such as Figure 1 , Figure 3 and Figure 6As shown, the machine body 1 vibrates to a certain extent when it is working, especially when the electric cylinder 21 strikes the filter box 19. Four sets of fixing plates 29 are installed at the bottom of the base 2, and sleeves 30 are set below the four sets of fixing plates 29. A second spring 32 is installed between the fixing plates 29 and the sleeves 30. The second spring 32 has a strong rebound force, which can effectively reduce the force in the vertical direction of the machine, thereby reducing the vibration amplitude of the machine.

[0035] Working principle: When using this invention, firstly, the material enters the machine body 1 through the feed port 5, and the shovel 10 rotates the material upward. The material is ground into powder between the grinding roller 11 and the grinding ring 12. The blower 13 is started via the control seat 4, and the blower 13 draws the powder into the collection box 14 through the suction cup 16 and the collection pipe 15. A first limiting ring 17 and a second limiting ring 18 are installed inside the machine body 1. A filter box 19 is movably connected between the first limiting ring 17 and the second limiting ring 18. A filter screen 20 is installed inside the filter box 19, which can effectively perform preliminary screening of the powder. Prolonged contact between the material and the filter screen 20 will cause blockage, reducing filtration efficiency. By starting the electric cylinder 21, the electric cylinder 21 extends downwards to strike the filter box 19, causing the blockage in the filter screen 20 to fall, thus cleaning the filter screen 20. Four sets of first springs 22 are installed between the filter box 19 and the second limiting ring 18. The first springs 22 can effectively return the filter box 19 to its original position, thereby extending the service life of the filter screen 20 and improving work efficiency. Secondly, the grinding roller 1... 1. When grinding materials for a long time, the grinding ring 12 is difficult to clean at the junction of the grinding roller 11 and the grinding ring 12. The residue will affect the purity of the grinding powder when different materials are replaced. By opening the cleaning door 27 by the handle 28, the two sets of movable ropes 25 are manually pulled. The movable ropes 25 drive the limit seats 24 on both sides of the support ring 23 to slide upward in the slide groove 26, thereby realizing the upward sliding of the grinding ring 12. When the grinding ring 12 reaches the cleaning door 27, the grinding ring 12 can be removed, thereby realizing the replacement and cleaning of the grinding ring 12. At the same time, the machine body 1 has a certain vibration when working, especially when the electric cylinder 21 hits the filter box 19. By installing four sets of fixing plates 29 at the bottom of the base 2, and setting the sleeve 30 below the four sets of fixing plates 29, a second spring 32 is installed between the fixing plates 29 and the sleeve 30. The second spring 32 has a strong rebound force, which can effectively reduce the force in the vertical direction of the machine, thereby reducing the vibration amplitude of the machine.
