Abstract
Description
Technical Field
[0001] This utility model relates to the field of Chinese medicinal material pulverization technology, and in particular to a pulverization mechanism for testing Chinese medicinal materials. Background Technology
[0002] Chinese medicinal herbs are unique medicines used in traditional Chinese medicine for the prevention and treatment of diseases. They are also an important feature that distinguishes traditional Chinese medicine from other medical systems. During the production process, Chinese medicinal herbs need to be processed, and during use, it is necessary to test the composition of the herbs, which requires the herbs to be pulverized.
[0003] For example, the prior art Chinese patent publication number "CN214514900U" provides a Chinese herbal medicine pulverizer, in which a first pulverizing cylinder is horizontally arranged inside the machine housing, and a first pulverizing protrusion is provided on the side wall of the first pulverizing cylinder. A screen is located inside the machine housing and below the first pulverizing cylinder. A pulverizing trough is horizontally arranged at the bottom of the machine housing. A second pulverizing cylinder is coaxially arranged inside the pulverizing trough, and a second pulverizing protrusion is provided on the outer wall of the second pulverizing cylinder. A driving mechanism is used to drive the first pulverizing cylinder and the second pulverizing cylinder to rotate.
[0004] This device, through the optimized design of the Chinese herbal medicine pulverizer, achieves coarse pulverization of Chinese herbal medicines by coordinating the first pulverizing cylinder with a screen. Then, the powder is coarsely filtered through the screen to ensure the particle size of the powder entering the pulverizing tank for fine pulverization, thereby improving pulverization efficiency and preventing incomplete pulverization caused by material adhesion.
[0005] Existing pulverizing mechanisms for testing Chinese medicinal materials do not provide sufficient pulverization in a single operation, failing to perform secondary pulverization and sieving. Furthermore, the sieving process does not adequately agitate the fragments, hindering the selection of qualified medicinal materials for testing. Additionally, fragments adhere to the grooves on the surface of the pulverizing rollers inside the pulverizing chamber, which, without proper cleaning, affects the effective pulverization of the medicinal materials.
[0006] Therefore, a pulverizing mechanism for the detection of Chinese medicinal materials is proposed. Utility Model Content
[0007] The purpose of this invention is to address the shortcomings of existing technologies where fragments of Chinese medicinal materials adhere to the surface grooves of the crushing roller and cannot be cleaned by brushing, thus affecting the effective crushing of Chinese medicinal materials. Therefore, this invention proposes a crushing mechanism for the detection of Chinese medicinal materials.
[0008] To achieve the above objectives, this utility model provides the following technical solution:

The first motor is installed at one end of the first crushing box, and the two first gears are meshed and connected to each other and installed at the other end of the first crushing box. A second guide plate is fixed at the bottom of the inside of the first crushing box. The second guide plate has an eight-shaped structure and is located directly above the second crushing box.
[0011] Furthermore, the movable mechanism includes a spring and a connecting column. The surface of the support leg has a insertion hole. The connecting column is fixed to the outside of the second crushing box and slides through the insertion hole. The spring is slidably sleeved on the surface of the connecting column and is located between the outside of the second crushing box and the inside of the support leg. An electric push rod is installed on the side of the support leg and at a position between the two connecting columns. The telescopic end of the electric push rod is fixedly connected to the outside of the second crushing box.
[0012] Furthermore, a third guide plate is fixed on both sides of the interior of the second crushing box, and a screening hole is opened on the surface of the third guide plate. A second crushing roller is rotatably installed inside the second crushing box and in the middle of the third guide plate.
[0013] Furthermore, a second motor is installed at one end of the second crushing roller, and a second gear is installed at the other end. The second motor is fixedly installed at one end of the second crushing box, and the two second gears are meshed and connected for transmission. They are also installed at the other end of the second crushing box. A fourth guide plate is fixed at the bottom of the interior of the second crushing box, and the fourth guide plate is located directly above the base.
[0014] Furthermore, both the first and second crushing boxes are rectangular box structures with open top and bottom. The support legs are vertically positioned, the first crushing roller is horizontally positioned, the first guide plate has a figure-eight structure with a larger top and smaller bottom, the connecting strip is horizontally positioned with both ends protruding outwards from the sides of the first crushing box, the outer end of the brushing strip makes brushing contact with the surface of the first crushing roller, and the mounting plate has a C-shaped cross-section for snap-fit installation of the connecting strip.
[0015] Furthermore, the connecting column is horizontally positioned, the electric push rod is horizontally positioned on one side of the second crushing box, and the spring is in a compressed state.
