[0017] The beneficial effects of this application are:

[0018] 1. The Chinese medicinal material grinding and powdering device pours the Chinese medicinal materials into the crushing box from the discharge port, and controls the servo motor to work. The servo motor drives the rotating shaft 1 and the active crushing knife to rotate, and the active crushing knife drives the active gear to rotate. Because the active gear is meshed with the driven gear, the active gear drives the driven gear to rotate synchronously in the opposite direction, and the driven gear drives the driven crushing knife to rotate. The driven crushing knife and the active crushing knife can be used to preliminarily crush the Chinese medicinal materials. The crushed Chinese medicinal materials are screened through a screen and then ground in the next step, which can reduce the time of each grinding as much as possible, reduce the heat generated during grinding, and make the crushing effect of the Chinese medicinal materials better, crush the Chinese medicinal materials more thoroughly, and help to grind the Chinese medicinal materials.

[0019] 2. The Chinese medicinal material grinding and powdering device, the driven gear drives the crown gear to rotate, the crown gear drives the rotating rod to rotate, the rotating rod thereby drives the belt to move, the belt drives the grinding shaft to rotate, the crushed Chinese medicinal materials fall into the grinding funnel and fall into the grinding bin shell, the grinding shaft drives the upper grinding wheel to rotate, and the opposite spiral convex grinding patterns between the grinding wheel and the grinding bin shell are used to grind the Chinese medicinal materials, so that the ground Chinese medicinal materials particles are more uniform, and the ground Chinese medicinal materials continue to fall into the discharge pipe and are discharged from the discharge inclined box.

[0020] 3. In the Chinese medicinal material grinding and powdering device, during the grinding process, coolant is added to the coolant storage box, and the cooling pipe is started to cool the coolant. When the rotating shaft 2 rotates, the rotating shaft 2 drives the rotating plate to move, and the rotating plate drives the push-pull plate to move through the connecting shaft, and the push-pull plate drives the push-pull seat and the extrusion plate to reciprocate, so that the extrusion plate drives the pressure plate to push and pull the coolant in the coolant storage box, and the coolant circulates in the cooling chamber through the connecting pipe 1 and the connecting pipe 2. The cooling chamber can be cooled by the circulation of the coolant, thereby reducing the problem of powder agglomeration caused by heat during the grinding process.

[0021] 4. The Chinese medicinal material grinding and powdering device, when the grinding shaft drives the grinding wheel to grind the Chinese medicinal material, the grinding wheel drives the rotating V-shaped frame to rotate with the grinding shaft as the axis, and when the rotating V-shaped frame contacts the collision piece, the grinding wheel vibrates, and then the collision piece is pushed to move into the limit box by the slope surface of the rotating V-shaped frame, and the collision piece pushes the gas in the limit box, and the gas is transported to the hollow column through the connecting hole, and the hollow column transports the gas to the cylinder through the air intake pipe, so that the gas in the cylinder pushes the collision block to collide with the bottom of the grinding bin shell, and the grinding bin shell vibrates, and the vibration generated by the grinding wheel and the grinding bin shell can ensure that the Chinese medicinal material can fall smoothly after grinding, and there will be no jamming in the powder cavity, so that the grinding of the Chinese medicinal material can proceed smoothly, thereby effectively improving the operating stability and efficiency of the grinding equipment.

[0022] 5. The Chinese medicinal material grinding and powdering device, when the grinding shaft rotates, the grinding shaft drives the reciprocating spiral rotating rod to rotate, because the L-shaped sliding rod restricts the blocking cover, thereby driving the hinge ring, the blocking cover and the L-shaped sliding rod to reciprocate and rise and fall through the reciprocating spiral rotating rod, and the blocking cover can close the connecting pipe, so that the crushed Chinese medicinal materials intermittently fall into the grinding bin shell, thereby controlling the intermittent feeding of the crushed Chinese medicinal materials to avoid affecting the grinding efficiency of the Chinese herbal medicines due to excessive or insufficient feeding amount. At the same time, when there are too many Chinese medicinal materials in the powder cavity, the blocking cover squeezes the Chinese medicinal materials in the powder cavity, so that the grinding wheel and the grinding bin shell are in close contact with the Chinese medicinal materials, which is helpful for grinding the Chinese medicinal materials and has higher grinding efficiency. At the same time, it prevents the Chinese medicinal materials from blocking the powder cavity. The grinding shaft drives the exhaust fan to rotate, and the exhaust fan generates downward suction on the Chinese medicinal materials in the powder cavity, so that the powder in the powder cavity is sucked out, which is convenient for discharging and collecting the powder, thereby improving the working efficiency of grinding.

The top of the grinding shaft 307 is provided with a blocking mechanism 7, and the blocking mechanism 7 includes a reciprocating spiral rotating rod 7 fixedly connected to the top of the grinding shaft 307. 01, the outer wall of the reciprocating spiral rotating rod 701 is meshedly connected with a hinge ring 702, the outer wall of the hinge ring 702 is fixedly connected with a blocking cover 703, the side wall of the blocking cover 703 is fixedly connected with a blocking cover 704, the inner wall of the grinding funnel 302 is fixedly connected with an L-shaped sliding rod 705, the outer wall of the L-shaped sliding rod 705 is slidably connected with the inner wall of the blocking cover 704, the outer wall of the grinding shaft 307 is fixedly connected with an exhaust fan 706, the exhaust fan 706 is located inside the discharge pipe 404, when the grinding shaft 307 rotates, the grinding shaft 307 The reciprocating spiral rotating rod 701 is driven to rotate, and the L-shaped sliding rod 705 restricts the blocking cover 704, so that the reciprocating spiral rotating rod 701 drives the hinge ring 702, the blocking cover 703 and the L-shaped sliding rod 705 to reciprocate and rise and fall, and the blocking cover 704 can seal the connecting pipe 406, so that the crushed Chinese medicinal materials intermittently fall into the grinding bin shell 402, so that the crushed Chinese medicinal materials can be controlled to be intermittently fed, avoiding the influence of the grinding efficiency of the Chinese medicinal materials on the feeding amount being too large or too small. When there are too many Chinese medicinal materials in the cavity 42, the sealing cover 704 squeezes the Chinese medicinal materials in the powder cavity 42, so that the grinding wheel 401 and the grinding bin shell 402 are in close contact with the Chinese medicinal materials, which is helpful for grinding the Chinese medicinal materials and improving the grinding efficiency. At the same time, it prevents the Chinese medicinal materials from blocking the powder cavity 42. The grinding shaft 307 drives the exhaust fan 706 to rotate, and the exhaust fan 706 generates a downward suction force on the Chinese medicinal materials in the powder cavity 42, so that the powder in the powder cavity 42 is sucked out, which is convenient for discharging and collecting the powder, thereby improving the grinding efficiency.

[0057] Specifically, the working principle of the Chinese medicinal material grinding and powdering device is as follows: Chinese medicinal materials are poured into the crushing box 103 from the discharge port 104, and the servo motor 102 is controlled to work, so that the servo motor 102 drives the rotating shaft 201 and the active crushing knife 202 to rotate, and the active crushing knife 202 drives the active gear 203 to rotate. Because the active gear 203 is meshed with the driven gear 204, the active gear 203 drives the driven gear 204 to rotate synchronously in the opposite direction, and the driven gear 204 drives the driven crushing knife 206 to rotate. The driven crushing knife 206 and the active crushing knife 202 can be used to preliminarily crush the Chinese medicinal materials. After crushing, the Chinese medicinal materials are screened by the screen 301 and then ground in the next step, so as to reduce the time of each grinding as much as possible, and reduce the heat generated during grinding, so that the crushing effect of the Chinese medicinal materials is better, and the Chinese medicinal materials are crushed more thoroughly, which is helpful for grinding the Chinese medicinal materials.

[0058] The driven gear 204 drives the crown gear 303 to rotate, the crown gear 303 drives the rotating rod 304 to rotate, the rotating rod 304 drives the belt 306 to move, the belt 306 drives the grinding shaft 307 to rotate, the crushed Chinese medicinal materials fall into the grinding funnel 302 and fall into the grinding chamber shell 402, the grinding shaft 307 drives the upper grinding wheel 401 to rotate, and the Chinese medicinal materials can be ground with the opposite spiral convex grinding patterns between the grinding wheel 401 and the grinding chamber shell 402, so that the ground Chinese medicinal materials particles are more uniform, and the ground Chinese medicinal materials continue to fall into the discharge pipe 404 and are discharged from the discharge inclined box 405;

[0059] During the grinding process, coolant is added to the coolant storage tank 507, and the cooling pipe 508 is started to cool the coolant. When the second rotating shaft 205 rotates, the second rotating shaft 205 drives the rotating plate 501 to move, and the rotating plate 501 drives the push-pull plate 503 to move through the connecting shaft 502, and the push-pull plate 503 drives the push-pull seat 504 and the extrusion plate 505 to reciprocate, so that the extrusion plate 505 drives the pressing plate 506 to push and pull the coolant in the coolant storage tank 507, and the coolant circulates in the cooling chamber 511 through the connecting pipe 1 509 and the connecting pipe 2 510. The cooling chamber 511 can be cooled by the circulation of the coolant, thereby reducing the problem of powder agglomeration caused by heat during the grinding process.

[0060] When the grinding shaft 307 drives the grinding wheel 401 to grind the Chinese medicinal materials, the grinding wheel 401 drives the rotating V-shaped frame 606 to rotate with the grinding shaft 307 as the axis. When the rotating V-shaped frame 606 contacts the collision member 605, the grinding wheel 401 vibrates. Then, the collision member 605 is pushed into the limit box 604 by the slope surface of the rotating V-shaped frame 606. The collision member 605 pushes the gas in the limit box 604, and the gas is transported to the hollow column 602 through the connecting hole 603. The hollow column 60 2. The gas is delivered to the cylinder 608 through the air inlet pipe 607, so that the gas in the cylinder 608 pushes the collision block 610 to collide with the bottom of the grinding chamber shell 402, and the grinding chamber shell 402 is vibrated. The vibration generated by the grinding wheel 401 and the grinding chamber shell 402 can ensure that the Chinese medicinal materials can fall smoothly after grinding, and will not be blocked in the powder cavity 42, so that the grinding of the Chinese medicinal materials can proceed smoothly, thereby effectively improving the operating stability and efficiency of the grinding equipment;

[0061] When the grinding shaft 307 rotates, the grinding shaft 307 drives the reciprocating spiral rod 701 to rotate. Since the L-shaped slide bar 705 restricts the blocking cover 704, the reciprocating spiral rod 701 drives the hinge ring 702, the blocking cover 703 and the L-shaped slide bar 705 to reciprocate and rise and fall. The blocking cover 704 can close the connecting pipe 406, so that the crushed Chinese medicinal materials intermittently fall into the grinding bin shell 402, so that the crushed Chinese medicinal materials can be controlled to be intermittently fed, avoiding excessive or insufficient feeding to affect the Chinese herbal medicine. Grinding efficiency. At the same time, when there are too many Chinese medicinal materials in the powder cavity channel 42, the blocking cover 704 squeezes the Chinese medicinal materials in the powder cavity channel 42, so that the grinding wheel 401 and the grinding bin shell 402 are in close contact with the Chinese medicinal materials, which is helpful for grinding the Chinese medicinal materials and has higher grinding efficiency. At the same time, it prevents the Chinese medicinal materials from blocking the powder cavity channel 42. The grinding shaft 307 drives the exhaust fan 706 to rotate, and the exhaust fan 706 generates a downward suction force on the Chinese medicinal materials in the powder cavity channel 42, so that the powder in the powder cavity channel 42 is sucked out, which is convenient for discharging and collecting the powder, thereby improving the grinding efficiency.

[0062] It should be noted that the specific models and specifications of the servo motor 102, cooling pipe 508 and exhaust fan 706 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be repeated in detail.
