[0026] like Figures 1 to 5As shown, this utility model provides an easy-to-clean pulverizer, including a frame 10, which serves as a support structure for supporting other components; a pulverizing chamber 20, mounted on the frame 10, with a detachable feed hopper 11 at the input end and a discharge chamber 12 connected to the output end; arc-shaped filter slots 21 on both inner walls of the output end of the pulverizing chamber 20, with a filter 22 movably inserted between the two sets of arc-shaped filter slots 21; a pulverizing mechanism 30, rotatably mounted inside the pulverizing chamber 20; a drive mechanism 40, mounted on the frame 10 and connected to the pulverizing mechanism 30 at its drive end, for driving the pulverizing mechanism 30; and a cleaning component 50, mounted on the pulverizing mechanism 30, with both ends extending towards the upper surfaces of the two sets of arc-shaped filter slots 21, the cleaning component 50 rotating synchronously with the pulverizing mechanism 30 to clean material debris adhering to the upper surfaces of the arc-shaped filter slots 21. The pulverizer in this application is a single-shaft pulverizer, and the cleaning component 50 can be directly added to an existing single-shaft pulverizer without the need for an additional power source; the cross-sections of the arc-shaped filter slot 21 and the filter screen 22 are both semi-circular arc-shaped and match the rotation radius of the pulverizing mechanism 30; the feed hopper 11 can be installed on the input end of the pulverizing chamber 20 by hinge on one side, or the whole can be detached by fasteners such as bolts and nuts, and can be opened up or completely removed to expose the interior of the pulverizing chamber 20 for easy inspection, cleaning and other operations; the discharge chamber 12 is used to receive qualified Chinese medicine granules that have been pulverized by the pulverizing mechanism 30 and filtered by the filter screen 22, and can be connected to an external discharge conveyor belt.
[0027] See Figure 3 and Figure 5 The crushing mechanism 30 includes a cutter wheel 31, which is rotatably mounted inside the crushing chamber 20 via a rotating shaft 32. The driving end of the driving mechanism 40 is connected to one end of the rotating shaft 32. Multiple sets of moving blades 33 are arranged axially on the outer wall of the cutter wheel 31, and at least one set of fixed blades 34 that can cooperate with the moving blades 33 are arranged on the inner wall of the crushing chamber 20. The cleaning assembly 50 is mounted on the outer wall of the cutter wheel 31. In this application, the three sets of moving blades 33 are circumferentially spaced on the cutter wheel 31. Two sets of fixed blades 34 are provided, located on opposite sides of the inner wall of the crushing chamber 20. The blade directions of the two sets of fixed blades 34 are opposite, specifically determined by the blade direction of the fixed blades 34 and the rotation direction of the cutter wheel 31, to ensure that the moving blades 33 and fixed blades 34 can cooperate to complete the cutting and crushing action, forming a shearing crushing process.
[0028] Specifically, the cleaning assembly 50 includes a mounting rod 51. An axial mounting groove 35 is formed on the outer wall of the blade wheel 31. The mounting rod 51 is disposed within the mounting groove 35. Slit brush heads 52 are provided at both ends of the mounting rod 51, opposite to the two sets of arc-shaped filter slots 21. The mounting rod 51 can be fixed within the mounting groove 35 by bolts and nuts, and can be disassembled for easy replacement of the slit brush heads 52. The slit brush head 52 can be a soft silicone brush head with a certain degree of flexibility, allowing it to conform to the upper surface of the arc-shaped filter slot 21; alternatively, a silicone scraper head can be used instead of the slit brush head 52.
[0029] Furthermore, to prevent the shredder from cutting into the crevice brush head 52, avoidance grooves are provided at both ends of the fixed blade 35 at positions corresponding to the crevice brush head 52. In this application, the lengths of both ends of all the moving blades 33 and fixed blades 34 do not reach the position of the filter slot 21, that is, the lengths of all the moving blades 33 and fixed blades 34 are the same as the width of the filter 22. The moving blades 33 and fixed blades 34 will not come into contact with the crevice brush head 52, and the cleaning assembly 50 and the moving blades 33 are arranged alternately on the blade wheel 31. The shredding action of the moving blades 33 and fixed blades 34 does not interfere with the cleaning action of the crevice brush heads 52 at both ends.
[0030] In a specific embodiment of this application, the drive mechanism 40 includes a rotary motor 41, a first pulley 42 is provided on the output end of the rotary motor 41, a second pulley 43 is provided on one end of the rotary shaft 32, a synchronous belt 44 is wound around the first pulley 42 and the second pulley 43, and the first pulley and the second pulley are connected by the synchronous belt 44 to drive the cutter wheel 31 to rotate.
[0031] See Figure 3 and Figure 4 The filter screen 22 has protruding edges 25 on both sides that can be installed in the arc-shaped filter slot 21. To further secure the filter screen 22, an mounting edge 26 is provided on one side of the inlet of the lower chamber 24, and a fixing plate 27 is provided on one end of the filter screen 22. The fixing plate 27 can be detachably installed on the mounting edge 26 by fastening bolts. During installation, the protruding edges 25 on both sides of the filter screen 22 are inserted into the arc-shaped filter slot 21. A hammer can be used to tap the end of the mounting edge 26 of the filter screen 22 to help it fully enter the arc-shaped filter slot 21. Then, the fixing plate 27 is fixed to the mounting edge 26 with bolts to achieve quick installation and removal. Arc-shaped reinforcing ribs can also be provided in the pulverizing chamber 20 to support the bottom of the filter screen 22, further strengthening the support and fixing strength of the filter screen 22.
[0032] See Figure 2In a specific embodiment of this application, the crushing chamber 20 includes an upper chamber 23 and a lower chamber 24. The lower chamber 24 is mounted on the frame 10. The upper chamber 23 is detachably mounted above the lower chamber 24. The feed hopper 11 is detachably mounted on the top of the input end of the upper chamber 23. The discharge chamber 12 is mounted on the output end of the lower chamber 24. Two sets of arc-shaped filter slots 21 are respectively provided on the inner walls of both sides of the output end of the lower chamber 24. The cutter wheel 31 is rotatably mounted inside the lower chamber 24. The fixed blade 34 is detachably mounted on the inner wall of the upper chamber 23. The upper chamber 23 and the lower chamber 24 are separable, making it easier to maintain the fixed blade and internal structure.
[0033] See further Figure 2 and Figure 6 To facilitate the cleaning of residual debris on the filter screen 22 and prevent clogging, the cleaning assembly 50 also includes a filter screen brush head 53. A brush head slot 54 is provided on the mounting rod 51, and a plug 55 at the bottom of the filter screen brush head 53 engages with the brush head slot 54. The filter screen brush head 53 extends into the arc-shaped inner surface of the filter screen 22 and can clean material debris adhering to the filter screen 22 as the crushing mechanism 30 rotates. Because the crushing actions of the moving blade 33 and the fixed blade 34 interfere with the filter screen brush head 53, the filter screen brush head 53 must be installed after removing the fixed blade 34 or opening the upper chamber 23 to clean the filter screen 22, replacing the traditional manual removal of the filter screen for cleaning. The filter screen brush head 53 can be made of stiff bristles for easy cleaning of the filter screen holes.
[0034] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
