The obtained Chinese herbal medicine powder is not uniform and fine, and is easily mixed with large particles. Operators are often required to filter and screen it, and put the screened large particles back into the crushing chamber for crushing. The number of repetitions is large, and it is very inconvenient to use.

[0045] like Figure 1 to Figure 15 As shown, on the basis of Example 1, this embodiment further includes a vibration unloading mechanism, which is installed inside the material guide bin 19 and is used to drive the vibration plate 10 and the internal vibration unloading process of the material guide bin 19.

[0046] Furthermore, the vibrating unloading mechanism also includes a crushing blade 23 and a ball-head knocking rod 24 for crushing and vibration connection.

[0047] Furthermore, the cooling grinding mechanism also includes a second motor 36 for driving the grinding roller 28 to reciprocate and grind, a grinding chamber 27 is opened in the grinding bin 25, a water storage chamber for storing water is provided in the heat conductive block 32, a hollow driving tube 33 is connected to the interior of the heat conductive block 32, a worm gear 34 is fixedly connected to the hollow driving tube 33, a worm 35 is meshingly connected to the worm gear 34, the worm 35 is fixedly connected to the output shaft of the second motor 36, the worm 35 is rotatably installed inside the box body 1, the second motor 36 is fixedly installed on one side of the grinding bin 25, a discharge pipe 54 is fixedly connected to the bottom of the grinding bin 25, and an electric valve 55 is provided on the discharge pipe 54.

[0048] Furthermore, the cooling and grinding mechanism also includes a second connecting water pipe 48 and a third connecting water pipe 51 for water supply and cooling. The second connecting water pipe 48 and the third connecting water pipe 51 are both fixedly mounted on the L-shaped fixing plate 40 through a limiting mounting block 52. The L-shaped fixing plate 40 is fixedly mounted on the side of the grinding chamber 25. One end of the hollow driving tube 33 is rotatably mounted on the limiting mounting block 52. The limiting mounting block 52 is provided with a rotating groove 53 adapted for rotational connection with the hollow driving tube 33, and a sealing ring is provided at the rotational connection between the hollow driving tube 33 and the rotating groove 53. The second connecting water pipe 48 and the third connecting water pipe 51 are both extended into the internal setting of the hollow driving tube 33, and the extension length of the second connecting water pipe 48 is greater than that of the third connecting water pipe 51. A plurality of water outlet holes 57 for water outlet are provided at the internal connection between the hollow driving tube 33 and the heat conducting block 32.

[0049] Furthermore, the cooling and grinding mechanism also includes a delivery box 45 and a piston plate 44 for circulating water connection. The delivery box 45 is fixedly installed on one side of the grinding bin 25. The delivery box 45 is connected to a water storage tank 50 through a first connecting water pipe 46. The water storage tank 50 is fixedly installed on one side of the grinding bin 25. A water pumping check valve 47 is provided on the first connecting water pipe 46. The second connecting water pipe 48 is connected to the interior of the delivery box 45. A water supply check valve 49 is provided on the second connecting water pipe 48. The piston plate 44 is connected to the interior of the delivery box 45 by a piston rod 43 through a limited sliding connection.

[0050] Furthermore, the cooling and grinding mechanism also includes a rotating disk 37 and a rotating connecting rod 39 connected to the piston plate 44 for driving the piston plate 44 to move back and forth. One end of the piston rod 43 is fixedly connected to the pressure plate 42, one end of the rotating connecting rod 39 is hingedly mounted on the pressure plate 42 through a hinge seat 41, and the other end of the rotating connecting rod 39 is rotatably mounted on the rotating disk 37 through a connecting rod 38, and the rotating disk 37 is fixedly connected to the worm 35.

[0051] Preferably, in this embodiment, when the screen 11 on the vibration plate 10 is undergoing screening processing, the output shaft of the second motor 36 drives the worm 35 to rotate, and the heat conductive block 32 on the hollow driving tube 33 is driven to rotate under the meshing connection between the worm 35 and the worm wheel 34. Due to the eccentric setting of the heat conductive block 32 and the adaptation of the heat conductive block 32 to be rotatably connected to the inside of the grinding roller 28, the grinding roller 28 is correspondingly driven to be close to the inner wall of the grinding chamber 27 for reciprocating grinding processing.

[0052] While the grinding roller 28 is moving back and forth up and down, it is also driving the lifting block 31 connected to one end of the connecting plate 29 to move back and forth inside the material guide bin 19, thereby driving the extension rod 16 connected to one end of the L-shaped sliding tooth plate 20 to move back and forth up and down. Due to the reciprocating contact connection relationship between the first annular protrusion 17 set at one end of the extension rod 16 and the second annular protrusion 18 set inside the connecting sleeve 15, the vibration plate 10 can be driven to vibrate back and forth and connected to the lower setting of the material guide block 9, thereby further improving the screening efficiency of the screen 11.

[0053] In addition, when the L-shaped sliding tooth plate 20 reciprocates up and down, the L-shaped sliding tooth plate 20 is meshed with the rotating gear 21, driving the rotating rod 22 to rotate back and forth continuously, so that the rotating rod 22 drives the crushing blade 23 and the ball head knocking rod 24 to rotate back and forth continuously. The rotation of the crushing blade 23 can crush the material screened from the screen 11 again, and because the ball head knocking rod 24 is arranged in contact with the inner wall of the material guide bin 19, the material guiding and unloading processing in the material guide bin 19 is further improved, so that the material in the material guide bin 19 can be further delivered to the grinding bin 25 for grinding.

[0054] By driving the screening vibration of the screen 11, the adhesion and bridging of particles can be effectively avoided, making the subsequent grinding process smoother. At the same time, it is also convenient for the vibration unloading treatment in the material guide bin 19. Through this processing method that combines grinding with vibration screening and vibration unloading, the automation and continuous production process of Chinese herbal medicine processing can be realized, which not only improves production efficiency, but also reduces the difficulty and cost of manual operation.

[0055] Since the grinding roller 28 is in constant contact with the material and is prone to generate high temperature, in order to solve this problem, the present application drives the worm 35 to rotate by the second motor 36, and at the same time drives the rotating disk 37 to rotate continuously, so that the pressing plate 42 is driven to move back and forth under the connection relationship of the rotating connecting rod 39, thereby driving the piston plate 44 to move back and forth inside the conveying box 45, and due to the one-way setting of the pumping check valve 47 set on the first connecting water pipe 46 and the one-way setting of the water supply check valve 49 set on the second connecting water pipe 48, the first connecting water pipe 4 The cooling water in the water storage tank 50 is drawn into the delivery box 45, and under the downward pressure of the piston plate 44, the drawn cooling water is injected into the interior of the hollow driving tube 33 through the second connecting water pipe 48. Since the hollow driving tube 33 is connected to the water storage chamber in the heat conductive block 32, the cooling water entering the hollow driving tube 33 is discharged from the water outlet 57 into the heat conductive block 32 for cooling. Under the heat conductive effect of the heat conductive block 32, the grinding roller 28 is well cooled, the loss of drug efficacy caused by high temperature is greatly reduced, and the grinding protection of the drug is achieved.

[0056] Since a water supply check valve 49 is provided on the second connecting water pipe 48 and the extension length of the second connecting water pipe 48 is greater than that of the third connecting water pipe 51, when cooling water is continuously injected into the second connecting water pipe 48, the excess cooled water in the heat conductive block 32 flows back to the third connecting water pipe 51 and enters the water storage tank 50, thereby realizing continuous circulation of water, thereby facilitating subsequent grinding operations and significantly improving work efficiency.

[0057] The water circulation cooling treatment inside the grinding roller 28 can effectively take away the heat of grinding and reduce the roller temperature, thereby protecting the grinding roller 28 and extending its service life. At the same time, it can make the grinding roller 28 work within a suitable temperature range, reduce the friction coefficient, improve the grinding efficiency and stability, and help maintain the stability of the medicinal material ingredients, making it easier to grind and process.

[0058] It should be particularly noted that the components in this application are all universal standard parts or components well known to those skilled in the art, which effectively solve the technical problems raised in the background technology.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
