A second crushing box 4 is fixedly installed on the left side of the conveying frame 3. A first discharge port 5 is opened at the bottom of the front side of the second crushing box 4. A crushing mechanism 6 is fixedly installed on the left side of the front side of the first crushing box 1. A screening mechanism 7 is embedded in the bottom of the inner wall of the conveying frame 3.
[0021] refer to Figure 2 and Figure 3The crushing mechanism 6 includes a first servo motor 61 and a second servo motor 62 fixedly installed on the front side of the second crushing box 4. The output ends of the first servo motor 61 and the second servo motor 62 are both fixedly connected to a drive shaft 63. The other end of the drive shaft 63 passes through the first crushing box 1 and the second crushing box 4 respectively and extends to the rear side of the first crushing box 1 and the second crushing box 4. The drive shaft 63 is movably connected to the first crushing box 1 and the second crushing box 4 through bearings. A first crushing wheel 64 is fixedly installed on the surface of the drive shaft 63. Several first crushing wheels 64 are provided and are distributed at equal intervals.
[0022] As a technical optimization of this utility model, by setting up a crushing mechanism 6, and by starting the first servo motor 61 and the second servo motor 62, the output ends of the first servo motor 61 and the second servo motor 62 can drive the transmission shaft 63 to rotate, and the rotation of the transmission shaft 63 can drive the first crushing wheel 64 to rotate.
[0023] refer to Figure 2 The screening mechanism 7 includes a screen plate 71, and a collection box 72 is fixedly connected to the bottom of the conveyor frame 3. A second discharge port 73 is opened on the front side of the collection box 72.
[0024] As a technical optimization of this utility model, by setting up a screening mechanism 7, the screen plate 71 can filter and screen the crushed raw materials entering the conveyor frame 3, so that the raw materials that meet the size requirements can pass through the screen plate 71 and enter the collection box 72, and be easily collected by the first discharge port 5.
[0025] refer to Figure 3 A driven shaft 8 is movably connected to the right side of the front wall of the first crushing box 1 and the top of the front wall of the second crushing box 4 via bearings. Several second crushing wheels 9 are fixedly installed on the surface of the driven shaft 8. The first crushing wheel 64 and the second crushing wheel 9 are arranged alternately. The other end of the driven shaft 8 passes through the first crushing box 1 and the second crushing box 4 respectively and is fixedly installed with a driven gear 10. The driven shaft 8 is movably connected to the first crushing box 1 and the second crushing box 4 via bearings. A transmission gear 11 is fixedly installed on the end of the transmission shaft 63 away from the first servo motor 61 and the second servo motor 62. The transmission gear 11 meshes with the driven gear 10.
[0026] As a technical optimization of this utility model, by setting a driven shaft 8, a second crushing wheel 9, a driven gear 10 and a transmission gear 11, the rotation of the transmission shaft 63 can drive the transmission gear 11 and the driven gear 10 to rotate, and the rotation of the driven gear 10 can drive the driven shaft 8 to rotate. At this time, the rotation directions of the transmission shaft 63 and the driven shaft 8 are opposite.
[0027] refer to Figure 1A mounting plate 12 is fixedly connected to the right side of the conveyor frame 3, and a blower 13 is fixedly installed on the top of the mounting plate 12. The output end of the blower 13 is connected to the right side of the inner wall of the conveyor frame 3 through a pipe.
[0028] As a technical optimization of this utility model, by setting up an installation plate 12 and a blower 13, the installation plate 12 can support and fix the blower 13. By starting the blower 13, the generated air force can enter the interior of the conveyor frame 3, thereby accelerating the blowing of the crushed raw material inside the conveyor frame 3 into the interior of the second crushing box 4.
[0029] refer to Figure 1 The right side of the inner wall of the first discharge port 5 and the second discharge port 73 are both connected by hinges to movable doors 14, and two support plates 15 are fixedly connected to the left side of the bottom of the conveyor frame 3.
[0030] As a technical optimization of this utility model, by setting up a movable door 14 and a support plate 15, the movable door 14 can block and close the first discharge port 5 and the second discharge port 73, and the support plate 15 can support the conveyor frame 3.
[0031] refer to Figure 1 and Figure 3 The bottom of the support plate 15 is fixedly connected to the bottom plate 16, the top left side of the bottom plate 16 is fixedly connected to the bottom of the second crushing box 4, and the inner wall of the second crushing box 4 is fixedly connected to the protective mesh plate 17.
[0032] As a technical optimization of this utility model, by setting a base plate 16 and a protective mesh plate 17, the overall integrity of the device can be improved by using the base plate 16, and the protective mesh plate 17 is located at the bottom of the first crushing wheel 64 in the second crushing box 4, which can prevent the user from coming into contact with the first crushing wheel 64 when collecting raw materials through the first discharge port 5.
[0033] The working principle and usage process of this utility model are as follows: When it is necessary to crush Chinese herbal raw materials, the first servo motor 61 and the second servo motor 62 are started first, so that the output ends of the first servo motor 61 and the second servo motor 62 drive the transmission shaft 63 to rotate. The rotation of the transmission shaft 63 can drive the first crushing wheel 64 to rotate. At the same time, the rotation of the transmission shaft 63 can drive the transmission gear 11 and the driven gear 10 to rotate. The rotation of the driven gear 10 can drive the driven shaft 8 to rotate. At this time, the transmission shaft 63 and the driven shaft 8 drive the first crushing wheel 64 and the second crushing wheel 9 to rotate in opposite directions. Then, the Chinese herbal raw materials are fed into the first crushing box 1 through the feed hopper 2, so that the first crushing wheel 64 and the second crushing wheel 9 inside the first crushing box 1 rotate in opposite directions. The crushing wheel 9 performs the initial crushing of the Chinese herbal medicine raw materials. The crushed Chinese herbal medicine falls into the interior of the conveyor frame 3. By starting the blower 13, the generated air force can enter the interior of the conveyor frame 3. At this time, the screen plate 71 can filter and screen the crushed raw materials entering the interior of the conveyor frame 3. The raw materials that meet the size requirements can pass through the screen plate 71 and enter the interior of the collection box 72. The raw materials that do not meet the size requirements can enter the interior of the second crushing box 4. The first crushing wheel 64 and the second crushing wheel 9 inside the second crushing box 4 perform secondary crushing of the Chinese herbal medicine raw materials. The crushed raw materials can fall through the protective net plate 17. After the crushing process is completed, the user can collect the crushed raw materials inside the collection box 72 and the second crushing box 4 by opening the movable door 14.
[0034] In summary, this raw material crushing device for the production of traditional Chinese medicine decoction pieces, by setting up a second crushing box 4 and a first discharge port 5, allows for secondary crushing of the raw materials. The first discharge port 5 facilitates the collection of the crushed raw materials by the user. This solves the problem that in existing crushing devices, due to the large differences in the individual volume of raw materials according to variety classification, raw materials that do not meet the crushing specifications after a single crushing need to be crushed again. Furthermore, the uneven particle size after a single crushing often leads to mixed fragments, making it inconvenient for users to sort and process them.
