[0032] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] See also Figure 1 and Figure 2 , Figure 1 It is a structural schematic diagram of an embodiment of a device for grinding and screening Chinese medicinal residues of the utility model; Figure 2 for Figure 1 The enlarged view of A in the figure. Figure 1 and Figure 2 As shown, the grinding and screening device for Chinese medicinal residues comprises an upper shell 11 and a lower shell 12, and the upper shell 11 can be arranged on the lower shell 12 by threaded connection, bonding, etc. A feeding port 13 connected to the interior of the upper shell 11 can be opened at the top of the upper shell 11, and the feeding port 13 is used to put the Chinese medicinal residues to be ground.

[0034] The device further includes a grinding assembly 2, which specifically includes a grinding head 21 and a grinding groove 22 disposed inside the upper housing 11. The grinding groove 22 is fixedly mounted to the bottom of the upper housing 11, and the circumferential surface of the grinding groove 22 serves as a grinding surface. Figure 1 direction) gradually to the left and right ( Figure 1 The bottom of the grinding tank 22 is provided with a feed pipe 27 which extends into the lower shell 12 and is used to transfer the ground particles to the lower shell 12.

[0035] The circumferential surface on the lower side of the grinding head 21 can be set to correspond to the inclination angle of the grinding groove 22 as a grinding surface. In the assembled state, a grinding gap 23 is formed between the grinding surface on the lower side of the grinding head 21 and the grinding surface of the grinding groove 22. The grinding gap 23 can be adapted to the desired particle size after grinding. The inclination angle of the grinding surface on the upper side of the grinding head 21 can be opposite to the inclination angle of the lower side grinding surface, so that there is space for the Chinese medicine residue to be ground.

[0036] The grinding assembly 2 may further include a transmission shaft 24 and a grinding motor 26. The grinding motor 26 may be disposed on the top of the upper housing 11. The upper end of the transmission shaft 24 is connected to the grinding motor 26, and the lower end of the transmission shaft 24 is rotatably connected to the upper end of the grinding head 21 through the upper housing 11. In the working state, the grinding motor 26 drives the transmission shaft 24 to rotate, thereby causing the grinding head 21 to rotate relative to the grinding tank 22, thereby grinding the Chinese medicine residue.

[0037] The device may also include an adjustment component, which is used to adjust the above-mentioned grinding gap 23. Specifically, the adjustment component may include a plurality of telescopic rods 31 arranged around the above-mentioned transmission shaft 24. The fixed end of the telescopic rod 31 may be fixed to the top of the upper shell 11. The telescopic end of the telescopic rod 31 is connected to the above-mentioned grinding motor 26. As an example, the above-mentioned telescopic rod 31 may be an electric push rod or an electromagnetic push rod. In the adjustment state, the above-mentioned multiple telescopic rods 31 are extended and retracted, which can drive the grinding motor 26, the transmission shaft 24 and the grinding head 21 to move up and down, thereby adjusting the above-mentioned grinding gap 23. Thereby, the Chinese medicine residue can be ground into particles of various specifications.

[0038] Furthermore, in order to prevent the torsion generated by the grinding head 21 during operation from affecting the grinding motor 26, the support strength of the telescopic rod 31 can be enhanced. The fixed end of each telescopic rod 31 can be connected by an annular reinforcing rod. In this way, the connection strength between the multiple telescopic rods 31 can be improved, thereby ensuring the normal operation of the grinding head 21.

[0039] That is, the transmission shaft 24 rotates relative to the upper housing 11 during the grinding operation, and slides relative to the upper housing 11 in the adjustment state. Therefore, a sleeve 25 can be fixed to the upper housing 11, and the transmission shaft 24 passes through the sleeve 25, so that the friction between the transmission shaft 24 and the upper housing 11 is reduced.

[0040] The device also includes a screen assembly 4. The screen assembly 4 includes a rotating rod 41, a rotating motor 42, a plurality of connecting rods 43, and a plurality of screens 44 with different apertures, which are arranged in the lower housing 12. The rotating motor 42 is installed at the bottom of the lower housing 12. Figure 1The upper end of the rotating rod 41 is connected to the top plate of the lower shell 12 so as to be rotatable around its own axis. Furthermore, a bearing can be provided on the top plate of the lower shell 12. The outer ring of the bearing is fixedly connected to the top plate of the lower shell 12, and the inner ring of the bearing is connected to the rotating rod 41. By providing the bearing, not only can the relative rotation between the rotating rod 41 and the lower shell 12 be achieved, but also the rotating rod 41 can support the top plate of the lower shell 12, thereby playing the role of supporting the upper shell 11.

[0041] A plurality of connecting rods 43 are evenly fixed on the circumference of the rotating rod 41. Each connecting rod 43 is connected to a screen 44. The screen 44 can be mounted on a screen frame 45, and the connecting rods 43 are connected to the screen frame 45. In the working state, the rotating motor 42 drives the rotating rod 41, which can drive the screen 44 to rotate, so that the corresponding screen 44 can be located below the discharge pipe 27, thereby performing a screening operation on the ground particles.

[0042] Further, in order to enhance the bearing capacity of the screen 44 during the screening process, the lower housing 12 can be configured to be circular. A plurality of steel balls 46 distributed in an annular shape can be embedded on the side wall of the lower housing 12. The screen frame 45 can be provided with grooves slidably connected to the plurality of steel balls 46. During the screening process, the connecting rod 43 and the steel balls 46 can provide a double supporting force for the screen 44, so that not only the stability of the screen 44 during the rotation process can be improved, but also the bearing capacity of the screen 44 can be improved.

[0043] Optionally, an annular groove may be provided on the side wall of the lower housing 12, and a projection may be provided on each screen frame 45. In the assembled state, the groove and the projection are slidably connected, which can also enhance the stability and load-bearing capacity of the screen 44 during rotation.

[0044] When the particles are sticky, they will accumulate in the screen 44, making it difficult to smoothly screen. In order to overcome the above problem, during the screening process, the rotating motor 42 can be used to drive the rotating rod 41 to rotate alternately in the forward and reverse directions at a small angle, so that the screen 44 can be vibrated, so that the particle screening operation can be completed smoothly.

[0045] When the screening operation is completed, the screen 44 can be rotated to the right side of the lower housing 12 ( Figure 1Direction in the middle). A detachable cover plate 14 can be provided at the top on the right side of the lower shell 12. By opening the cover plate 14, the larger particles left on the screen 44 can be taken out for secondary grinding. It should be noted that, in order to facilitate the removal of the screen 44 and the larger particles left, the screen 44 can be detachably connected to the screen frame 45. Those skilled in the art can make arrangements based on common knowledge or prior art. As an example, an annular baffle can be provided at the bottom of the above-mentioned screen frame 45, and the above-mentioned screen 44 can be placed above the annular baffle, thereby realizing the detachable connection between the screen 44 and the screen frame 45.

[0046] A collection box 5 may be provided at the bottom of the screen 44 for collecting qualified particles after screening. The collection box 5 may be slidably connected to the bottom of the lower shell 12, and an opening 52 may be provided at a corresponding position of the side wall of the lower shell 12 for moving the collection box 5 out of the lower shell 12. In this way, the collection box 5 may be pulled out by pulling a handle 51 fixed to the collection box 5. A sliding steel ball or a slide rail may be provided at the bottom of the lower shell 12 so that the collection box 5 can slide relative to the lower shell 12.

[0047] Furthermore, in order to place the collection box 5 in a suitable position to collect qualified particles, the rotating motor 42 can be used as a stopper to determine the position of the collection box 5, that is, when the collection box 5 abuts against the rotating motor 42, it indicates that the collection box 5 has been placed in place.

[0048] The device can adjust the grinding gap 23 by adjusting the extension length of the telescopic rod 31. A corresponding relationship table between the aperture sizes of the screen 44 corresponding to the extension length can be prepared. After the grinding gap 23 is determined by the extension length, the corresponding screen 44 is rotated to the bottom of the feeding pipe 27 by the rotating motor 42 according to the corresponding relationship table.

[0049] The device may also include a control end, which is connected to the telescopic rod 31 and the rotating motor 42. The staff can transmit the particle size to be ground to the control end according to the human-machine interaction button. The control end controls the movement of the telescopic rod 31 so that the grinding gap 23 is adapted to the particle size. Next, the control end can also determine the matching screen 44 according to the above-mentioned correspondence table, and then control the rotating motor 42 to rotate the matching angle to rotate the screen 44 under the feeding pipe 27. Specifically, the initial angle information and aperture information of each screen 44 can be input into the control end in advance. In this way, after determining the matching aperture information, the control end controls the rotation of the screen 44 according to the above-mentioned initial angle information and the rotation angle of the rotating motor 42. Thereby improving the degree of automation of the device.
