[0020] The improvement of this embodiment is that:

[0021] The utility model takes into account the existing micro-plant crusher with automatic screening for graded crushing. After the plants are crushed, they are screened through a screen. The screening plates of most devices are fixedly installed, so that the screening speed of the crushed plants when they are screened through the screen is slow, and they are easy to accumulate on the top of the screen, thereby affecting the working efficiency of the device. In addition, after the screening is completed, some devices take out the large plant particles that are not completely crushed filtered on the screen by the staff, and then perform secondary crushing on the large plant particles that are not completely crushed. This method is not only time-consuming and labor-intensive, but also the large plant particles that are not completely crushed and accumulate on the screen may block the screen, thereby affecting the screening efficiency and reducing the use effect of the device. Therefore, a crushing mechanism 2 is set to crush the plants, and the screening mechanism 3 is driven by a driving mechanism 4 to sieve left and right, thereby improving the screening efficiency of the device. The large plant particles that are not completely crushed can directly fall onto the auxiliary mechanism 5 for secondary crushing, and the secondary crushing of the large plant particles that are not completely crushed can be completed without manually taking out the large plant particles that are not completely crushed, thereby improving the working efficiency of the device.

[0022] Considering the need to pulverize the plants, the structure of the pulverizing mechanism 2 is further disclosed, such as Figure 3 As shown, the crushing mechanism 2 includes two No. 1 crushing rollers 21 rotatably connected to the inner wall of the body 1, and the two No. 1 crushing rollers 21 are meshedly connected. One side of the two No. 1 crushing rollers 21 passes through the rear side of the body 1. One of the No. 1 crushing rollers 21 passes through one side of the body 1 and is fixedly installed with a driving motor 22. The driving motor 22 is started to drive one of the No. 1 crushing rollers 21 to rotate. The two No. 1 crushing rollers 21 pass through one side of the body 1 and are fixedly connected with a No. 1 gear 23, and the two No. 1 gears 23 are meshedly connected. When one of the No. 1 crushing rollers 21 rotates, it cooperates with the two No. 1 gears 23 to drive the other No. 1 crushing roller 21 to rotate, so that the two No. 1 crushing rollers 21 rotate, and the plants added into the body 1 through the feed hopper on the top of the body 1 are preliminarily crushed.

[0023] Considering the need to screen the crushed plants, the structure of the screening mechanism 3 is further disclosed, such as Figure 3 and Figure 4 As shown, the screening mechanism 3 includes a support column 31 fixedly connected to the front and rear sides of the body 1, and a moving rod 32 is rotatably connected to the support column 31. The side of the moving rod 32 away from the support column 31 is rotatably connected to a screen plate 33. The screen plate 33 is inclined to facilitate subsequent secondary crushing of large plant particles that are not completely crushed. When the screen plate 33 moves, the moving rod 32 can be pulled to move. The support column 31 and the moving rod 32 are provided to provide stability for the screen plate 33 when it moves.

[0024] In order to drive the screening mechanism 3 to operate, the structure of the driving mechanism 4 is further disclosed, such as Figure 3 As shown, the driving mechanism 4 includes two support plates 41 fixedly connected to one side of the machine body 1, and the support plates 41 are rotatably connected to fixed rods 42, one side of one of the fixed rods 42 passes through the connected support plate 41, and a No. 1 belt 43 is sleeved on one side of the fixed rod 42 that passes through the support plate 41, and the No. 1 belt 43 is sleeved on the adjacent No. 1 crushing roller 21 away from the side of the fixed rod 42. When the No. 1 crushing roller 21 rotates, it cooperates with the No. 1 belt 43 to drive one of the fixed rods 42 to rotate. A mounting plate 44 is fixedly connected to the machine body 1, and the mounting plate 44 is located between the two support plates 41. The mounting plate 44 is rotatably connected to the mounting plate 44. A rotating rod 45 is connected, and the rotating rod 45 passes through the mounting plate 44. A connecting rod 46 is fixedly connected between the fixed rod 42 and the adjacent rotating rod 45. The fixed rod 42, which is sleeved with a No. 1 belt 43, rotates, driving the connecting rod 46 to rotate, thereby driving the rotating rod 45 to rotate, and then driving another fixed rod 42 to rotate. The outer wall of the connecting rod 46 is rotatably connected with a pull rod 47, and the side of the pull rod 47 away from the connecting rod 46 is rotatably connected to the bottom of the sieve plate 33. When the connecting rod 46 rotates, the pull rod 47 can be pulled to move left and right, thereby driving the sieve plate 33 to move left and right, and the crushed plants are screened.

[0025] In order to perform secondary crushing on the incompletely crushed large plant particles, the structure of the auxiliary mechanism 5 is further disclosed. Figure 3 and Figure 4 As shown, the auxiliary mechanism 5 includes two No. 2 crushing rollers 51 rotatably connected to the inner wall of the body 1, and the two No. 2 crushing rollers 51 are meshedly connected. One side of the two No. 2 crushing rollers 51 passes through the rear side of the body 1. One of the No. 2 crushing rollers 51 passes through the side of the body 1 and is sleeved with a No. 2 belt 52, and the side of the No. 2 belt 52 away from the No. 2 crushing roller 51 is sleeved on the adjacent No. 1 crushing roller 21. When the two No. 1 crushing rollers 21 rotate, they cooperate with the No. 2 belt 52 to drive one of the No. 2 crushing rollers 51 to rotate. The two No. 2 crushing rollers 51 pass through one side of the body 1 and are fixedly connected with a No. 2 gear 53, and the two No. 2 gears 53 are meshedly connected. When one of the No. 2 crushing rollers 51 rotates, it cooperates with the two No. 2 gears 53 to drive the other No. 2 crushing roller 51 to rotate, so that the two No. 2 crushing rollers 51 mesh and rotate, and the large plant particles that are not completely crushed are secondary crushed, thereby improving the use effect of the device.

[0026] When the micro-plant crusher with automatic screening and graded crushing of the utility model is used, plants to be crushed are added into the machine body 1 through the feed hopper on the top of the machine body 1, and the driving motor 22 is started to drive one of the first crushing rollers 21 to rotate, and the other first crushing roller 21 can be driven to rotate with the two first gears 23, so as to perform preliminary crushing on the plants, and the plants after preliminary crushing fall onto the sieve plate 33 and are filtered through the sieve plate 33;

[0027] The No. 1 crushing roller 21 rotates in coordination with the No. 1 belt 43, driving one of the fixed rods 42 to rotate, thereby driving the connecting rod 46 to rotate, and then driving the rotating rod 45 to rotate. The rotating rod 45 rotates, which can drive the other fixed rod 42 to rotate. The connecting rod 46 rotates, which can pull the pull rod 47 to move left and right, thereby driving the sieve plate 33 to move left and right. Since the sieve plate 33 is inclined, during the sieve plate 33 sieving process, the large plant particles that are not completely crushed fall onto the two No. 2 crushing rollers 51;

[0028] When the two No. 1 crushing rollers 21 rotate, they cooperate with the No. 2 belt 52 to drive one of the No. 2 crushing rollers 51 to rotate, and cooperate with the two No. 2 gears 53 to drive the other No. 2 crushing roller 51 to rotate, so that the two No. 2 crushing rollers 51 are meshed and rotated, and the large plant particles that are not completely crushed are crushed for the second time, thereby improving the use effect of the device.
