[0028] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0029] See also Figure 1-Figure 8 A crushing and mixing device for Chinese herbal medicine slices comprises four supporting legs, the tops of the four supporting legs are fixedly connected with a stirring bin 1, the top of the stirring bin 1 is provided with four grinding bins 2, the four grinding bins 2 are arranged in a line, so as to process different Chinese herbal medicine slices respectively, each grinding bin 2 is rotatably connected with a pair of crushing rollers 4, which are used for preliminary crushing of the Chinese herbal medicine slices entering the grinding bin 2, in order to drive all the crushing rollers 4 to rotate synchronously, a first driving assembly is arranged on the grinding bin 2, and a feeding bin 3 is provided on the top of each grinding bin 2, and a feeding channel is passed through the bottom of the feeding bin 3. 15 is connected with the top of the grinding chamber 2, the lower part of the grinding chamber 2 passes through the top of the mixing chamber 1 and is provided with a plurality of sieve holes 201, these sieve holes 201 allow the powder particles that reach the qualified particle size after crushing and grinding to fall into the mixing chamber 1, a grinding plate 5 is rotatably arranged in the grinding chamber 2, a second driving assembly is arranged on the grinding chamber 2, the second driving assembly is used to drive the grinding plate 5 to rotate periodically along the inner wall of the grinding chamber 2, one side of the grinding plate 5 is tightly fitted with the inner wall of the grinding chamber 2, the other side of the grinding plate 5 is connected with a lifting plate 6, and the grinding plate 5 and the lifting plate 6 are connected by The rotating shaft is rotatably connected, and two torsion springs 601 are installed on the rotating shaft. A convex block 602 is connected to the lifting plate 6. When the grinding plate 5 and the inner wall of the grinding chamber 2 are not in contact with the lower opening of the feed channel 15, the convex block 602 contacts the inner wall of the grinding chamber 2, so that the lifting plate 6 rotates to form a hook shape between the grinding plate 5 and the grinding plate 5 that can capture the Chinese medicine particles. The torsion spring 601 is deformed. When the grinding plate 5 rotates to the inner top of the grinding chamber 2, that is, below the lower opening of the feed channel 15, the convex block 602 is separated from the contact with the inner wall of the grinding chamber 2. The lifting plate 6 will rotate under the elastic action of the torsion spring 601 and will no longer form a hook shape with the grinding plate 5. At this time, the captured Chinese medicine particles will fall naturally. Two cooling plates 9 are arranged in the grinding chamber 2. The two cooling plates 9 are arranged in an inverted eight shape above the two crushing rollers 4. The Chinese medicine particles released after being lifted by the hook shape formed by the lifting plate 6 and the grinding plate 5 will fall naturally. The two cooling plates 9 can guide the Chinese medicine particles to contact with each other and reduce the temperature of the Chinese medicine particles during the mutual contact process, thereby reducing the loss of nutritional components of the medicinal materials caused by frictional heat.

[0030] The grinding plate 5 has a surface that is in contact with the inner wall of the grinding bin 2 with a plurality of grinding strips 501, and the inner wall of the grinding bin 2 has striped grooves 202 that match the grinding strips 501. When the grinding plate 5 rotates, the grinding strips 501 will move along the trajectory of the striped grooves 202, and repeatedly squeeze and grind the Chinese medicine particles that fall into the grinding bin 2 until they reach the required fineness. When the medicinal powder reaches the required fineness, the gap between the grinding strips 501 and the striped grooves 202 will gradually increase, so that the medicinal powder can smoothly fall from the sieve holes 201 of the grinding bin 2, thereby avoiding the deterioration of the medicinal powder quality caused by excessive grinding.

[0031] The first driving assembly includes a driving shaft 701 and a motor 702. Two driving shafts 701 are connected to the middle of multiple grinding bins 2 for common rotation. The two crushing rollers 4 of each grinding bin 2 are detachably connected to the two driving shafts 701. Motor 1 702 is installed on the left side of the leftmost grinding bin 2. The output shaft of motor 1 702 is connected to one of the driving shafts 701 through transmission. One end of the two driving shafts 701 is connected through transmission through a gear assembly 703. Specifically, the gear assembly 703 includes two large gears meshing with each other. When motor 1 702 is started, its output shaft drives one of the driving shafts 701 to rotate. Since the two driving shafts 701 are connected through the gear assembly 703, the other driving shaft 701 will also rotate synchronously. In this way, the two crushing rollers of each grinding bin can rotate at the same time to perform preliminary crushing of the Chinese medicine raw materials.

[0032] The second driving assembly includes a rotating ring 801 and a second motor 802. The rotating ring 801 is rotatably connected to the grinding chamber 2. There are two grinding plates 5, and the two grinding plates 5 are connected to the rotating ring 801. A small gear 803 is rotatably provided in the grinding chamber 2. A gear ring 804 meshing with the small gear 803 is provided on the inner side of the rotating ring 801. The second motor 802 is installed on the outer wall of the grinding chamber 2. The output shaft of the second motor 802 is connected to the small gear 803 in a transmission manner. When it is necessary to grind the powder, the second motor 802 will start and drive the small gear 803 to rotate. The rotation of the small gear 803 drives the rotating ring 801 and the grinding plate 5 connected thereto to rotate together through the gear ring 804.

[0033] A cooling box 901 is provided at the front side of the mixing chamber 1 , and the cooling plate 9 is connected to the cooling box 901 via a cooling pipe 902 . The cooling plate 9 can be continuously cooled by the circulation of the coolant in the cooling pipe 902 in the cooling box 901 .

[0034] A dividing barrel 10 is horizontally rotatably connected in the feed bin 3, and two quantitative grooves 11 are provided on the dividing barrel 10 to facilitate the delivery of an appropriate amount of Chinese herbal medicines into the grinding bin 2 each time. A motor 3 12 is installed on the front side of the feed bin 3, and the output shaft of the motor 3 12 is transmission-connected to the dividing barrel 10. A feed port is provided on the top of the feed bin 3, and the dividing barrel 10 is driven to rotate by controlling the motor 3 12, thereby realizing the quantitative addition of Chinese herbal medicines.

[0035] A stirring rod 13 is horizontally rotatably connected in the stirring bin 1, and a motor 4 14 is installed on the left side of the stirring bin 1. The output shaft of the motor 4 14 is transmission-connected to the stirring rod 13. The stirring rod 13 is driven to rotate by controlling the motor 4 14, so that the powder in the stirring bin 1 can be stirred and mixed. A discharge port is provided at the bottom of the stirring bin 1, and a sealing plate 16 is rotatably connected to the discharge port.

[0036] Working principle: Initially, the protrusion 602 contacts the inner wall of the grinding chamber 2, so that the lifting plate 6 and the grinding plate 5 form a hook shape, the torsion spring 601 is deformed to store elastic potential energy, and the sealing plate 16 is in a closed state for the discharge port of the mixing chamber 1.

[0037] When in use, firstly, different Chinese medicine raw materials are respectively fed into the corresponding feed bin 3 through different feed ports, and then, the motor 3 12 is used to drive the dividing barrel 10 to rotate. The Chinese medicine raw materials are respectively transferred by the two quantitative grooves 11 of the dividing barrel 10, so that an appropriate amount of Chinese medicine raw materials fall into the corresponding grinding bin 2 below each time, and then the crushing rollers 4 of all the grinding bins 2 are driven to rotate by the first driving component to preliminarily crush the Chinese medicine raw materials into Chinese medicine particles.

[0038] After preliminary crushing, the Chinese medicine particles fall into the bottom of the grinding bin 2 by gravity. At this time, the grinding plate 5 is driven by the second driving component to rotate periodically along the inner wall of the grinding bin 2. The grinding strips 501 on the grinding plate 5 interact with the striped grooves 202 on the inner wall of the grinding bin 2 to finely grind the Chinese medicine particles. As the Chinese medicine particles are gradually ground into powder of qualified fineness, the powder can fall into the mixing bin 1 through the sieve holes 201 on the grinding bin 2.

[0039] During the grinding process, the hook shape formed between the grinding plate 5 and the lifting plate 6 can capture the Chinese medicine particles at the bottom of the grinding chamber 2. When the grinding plate 5 rotates to the top of the grinding chamber 2, the protrusion 602 breaks away from the contact with the inner wall of the grinding chamber 2, and the lifting plate 6 rotates under the elastic action of the torsion spring 601, and no longer forms a hook shape with the grinding plate 5. At this time, the lifted Chinese medicine particles will naturally fall down under the action of their own gravity, and under the guidance of the two cooling plates 9, they will pass through the two crushing rollers 4 and fall into the bottom of the grinding chamber 2. Subsequently, the grinding plate 5 continues to rotate. Under the movement, the protrusion 602 on the lifting plate 6 contacts the inner wall of the grinding bin 2 again, and applies pressure to the lifting plate 6, so that the lifting plate 6 rotates in the opposite direction and resets. In this way, through the continuous rotation of the grinding plate 5, the Chinese medicine particles undergo multiple grinding, lifting and falling processes in the grinding bin 2 until they reach the qualified fineness and are sieved out from the sieve hole 201, ensuring the fineness uniformity of the final output of the medicine powder. At the same time, when the Chinese medicine particles contact the two cooling plates 9 during the falling process, their temperature will be reduced, thereby preventing the quality of the ground medicine powder from being affected by the heat generated by friction.

[0040] Finally, the medicinal powders produced in the multiple grinding bins 2 all fall into the stirring bin 1, and the stirring rod 13 is driven by the motor 4 14 to rotate continuously. The stirring rod 13 stirs different types of medicinal powders to ensure that the various Chinese medicinal ingredients can be mixed evenly. When the stirred medicinal powder needs to be taken out, the medicinal powder can be discharged through the discharge port by opening the sealing plate 16.
