A plurality of filter holes 19 connected to the outside are evenly opened at the bottom end of the tamping column 15, so that the crushed material can enter the collecting box 7 through the filter holes 19.

[0026] The tamping column 15 is provided with a shielding component, which cooperates with the tamping column 15 to shield it, so as to prevent the material from splashing and the powder of the material from scattering during the tamping process.

A threaded barrel 12 is fixedly arranged at the bottom end of the horizontal rod. The threaded block 18 is rotatably arranged in the threaded barrel 12, and the threaded block 18 is threadedly connected to the threaded barrel 12. The rotating shaft 13 passes through the threaded barrel 12 and extends into the threaded barrel 12 and is fixedly connected to the threaded block 18.

The limiting groove 26 extends into the horizontal rod and communicates with the groove, and the limiting block 17 and the limiting groove 26 are limited and slidably matched.

[0028] The shielding assembly includes a baffle 10. There are two baffles 10, and a T-shaped slot is provided on the ramming column 15, and the baffle 10 is slidably set in the T-shaped slot. The baffle 10 is semicircular, and the two baffles 10 are symmetrically arranged about the axis of the rotating shaft 13. Semicircular holes are provided in the middle position of one side of the two baffles 10 close to the rotating shaft 13, and the semicircular holes of the two baffles 10 form a circular hole, which is adapted to the rotating shaft 13 to prevent the baffle 10 from interfering with the rotating shaft 13 when moving, so that the two baffles 10 fit tightly. The baffle 10 is in transmission cooperation with the second driving mechanism, so that the two baffles 10 are close to each other or away from each other.

[0029] The second driving mechanism includes a threaded rod 20. Support plates 8 are welded to both sides of the upper end of the outer circumferential surface of the ramming column 15. There are two threaded rods 20, and the two threaded rods 20 correspond to the support plates 8 one by one. The support plates 8 are provided with through grooves, and the threaded rods 20 are rotatably arranged in the through grooves of the corresponding support plates 8. The threaded rods 20 correspond to the baffles 10 one by one, and the baffles 10 are threadedly connected to the corresponding threaded rods 20. The two threaded rods 20 have opposite threaded rotation directions.

[0030] The material storage mechanism includes a storage box 2. The storage box 2 is fixedly mounted on one of the vertical rods. A slide plate 3 is slidably mounted on the upper end surface of the storage box 2 to facilitate adding materials into the storage box 2. The storage box 2 is connected to the tamping column 15 through a conduit 4. Specifically, a conduit 4 connected to the inside of the storage box 2 is fixedly connected to the bottom end of the storage box 2, and the conduit 4 passes through the vertical rod and is connected to the tamping column 15. The conduit 4 is tilted to facilitate the material to enter the tamping column 15 better. The bottom end of the storage box 2 is tilted toward the direction of the conduit 4 to facilitate the material to enter the tamping column 15 through the conduit 4.

[0031] A slide groove 6 is provided on the vertical rod near the conduit 4, and the slide groove 6 is arranged vertically. The slide groove 6 passes through the conduit 4 and extends to the bottom of the conduit 4. A stopper 16 is provided in the slide groove 6 to slide up and down. The stopper 16 is adapted to the conduit 4 to block the conduit 4. An L-shaped plate 5 is fixedly provided on one side of the lower part of the stopper 16, and the L-shaped plate 5 passes through the vertical rod and extends out of the vertical rod.

[0032] In summary, in the initial state, materials are stored in the storage box 2. The block 16 blocks the conduit 4, and the two baffles 10 are away from each other.

[0033] When the material is to be crushed, the L-shaped plate 5 is moved, and the L-shaped plate 5 causes the block 16 to move upward in the chute 6, and the block 16 gradually stops blocking the conduit 4. The material enters the tamping column 15 through the conduit 4. After the material enters, the L-shaped plate 5 is released, and the block 16 moves down along the chute 6 with the L-shaped plate 5, and the block 16 blocks the conduit 4 again.

[0034] The second motor 11 is started, and the second motor 11 rotates the threaded block 18 , which drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the ramming hammer 14 to rotate, and the ramming hammer 14 rotates in the ramming column 15 to crush the material in the ramming column 15 .

[0035] At the same time, the threaded block 18 rotates to move the threaded block 18 downward, and the threaded block 18 moves the second motor 11 and the rotating shaft 13 downward, and the rotating shaft 13 moves the ramming hammer 14 downward, and the ramming hammer 14 crushes the material in the ramming column 15.

[0036] The two first motors 9 are started at the same time, and the first motors 9 make the threaded rod 20 rotate in the forward direction, and the threaded rod 20 makes the two baffles 10 move toward each other, so that the two baffles 10 completely block the tamping column 15, to prevent the material from splashing and causing waste of material during the tamping process, and to prevent the powder of the material from scattering.

[0037] The second motor 11 is reversed, and the second motor 11 rotates the threaded block 18, which drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the ramming hammer 14 to rotate, and the ramming hammer 14 rotates in the ramming column 15 to crush the material in the ramming column 15. At the same time, the threaded block 18 moves upward, and the threaded block 18 drives the second motor 11 and the rotating shaft 13 to move upward, and the rotating shaft 13 drives the ramming hammer 14 to move upward.

[0038] At the same time, the two first motors 9 are reversed, and the first motors 9 rotate the threaded rod 20, and the threaded rod 20 moves the two baffles 10 away from each other, so as to facilitate observation of the crushing of the material in the tamping column 15. This is repeated to crush and beat the material, so that the crushing effect is better.

[0039] The crushed material enters the collecting box 7 through the filter hole 19. When the material in the collecting box 7 is collected to a certain extent, the first motor 9 and the second motor 11 are stopped. The collecting box 7 is taken out and the crushed material is processed.

[0040] Example 2

[0041] like Figure 5-Figure 6 The crushing device shown here only introduces the differences from Example 1, and the other identical parts are not described in detail here.

[0042] The second driving mechanism includes a support rod 21. A bearing plate 25 is provided on the rotating shaft 13, and the bearing plate 25 is connected to the rotating shaft 13 through a bearing 24. A bearing seat is provided in the middle position of the bearing plate 25, and the bearing 24 is installed on the bearing seat, so that the bearing plate 25 is convenient to be connected to the rotating shaft 13 through the bearing 24. Four articulated frames 22 are welded to the upper end of the bearing plate 25, and two articulated frames 22 form a group. Two articulated frames 22 are fixedly connected to the bottom end of each baffle 10, and the articulated frames 22 on the baffle 10 correspond one-to-one to the articulated frames 22 on the bearing plate 25. There are four support rods 21, and the support rods 21 correspond one-to-one to the articulated frames 22. The support rods 21 and the corresponding articulated frames 22 are hinged by bolts 23.

[0043] In summary, in the initial state, the two baffles 10 are in an open state. The two groups of support rods 21 are V-shaped.

[0044] When the first driving mechanism rotates the tamping hammer 14 and moves downward at the same time, the rotating shaft 13 moves downward with the bearing plate 25, and the bearing plate 25 moves downward with the hinged frame 22 on the bearing plate 25. The hinged frame 22 moves the two baffles 10 toward each other through the support rod 21, thereby blocking the tamping column 15 to prevent the material from splashing and causing waste of material during the tamping process, and also to prevent the powder of the material from floating out during the tamping process.

[0045] The second motor 11 is reversed, and the second motor 11 causes the threaded block 18 to reverse. The threaded block 18 moves the second motor 11 and the rotating shaft 13 upward, and the rotating shaft 13 moves the bearing plate 25 upward. The bearing plate 25 moves the two baffles 10 away from each other through the support rod 21, so that the pounding condition of the material in the tamping column 15 can be observed.

[0046] Repeat the above operation to crush the material in the tamping column 15 to achieve a better crushing effect. The crushed material enters the collecting box 7 through the filter hole 19. When the material in the collecting box 7 is collected to a certain extent, the second motor 11 stops. The collecting box 7 is taken out and the crushed material is processed.
