Description

Technical Field

[0001] The present application relates to the technical field of grinding devices, and in particular to a device for finely grinding and mixing Chinese medicinal materials containing spices. Background Art

[0002] Chinese herbal medicines are of various types and sources. They have various chemical components. They are natural medicines that can prevent, treat and diagnose diseases. These Chinese herbal medicines can be used to treat various diseases and regulate the body's yin and yang balance through different combinations and formulas. Among them, in order to improve utilization, facilitate use, adapt to modern preparations, and promote component release, Chinese herbal medicines need to be crushed and mixed.

[0003] Among them, the crushed Chinese medicinal materials are crushed and mixed by grinding equipment, such as a Chinese medicinal material efficient fine grinding device with publication number CN218107921U, which sets semicircular gears and intermittent gears, and uses a swing motor to rotate the intermittent gears to drive the grinding bucket to swing back and forth. The grinding bucket that swings back and forth can increase the grinding range of the grinding head, thereby reducing the grinding dead angle and avoiding uneven grinding. By setting a sleeve and a push rod, when the swing motor drives the grinding bucket to swing, the cooperation of the push rod and the block can be used to fix the grinding bucket, thereby reducing the workmanship of the swing motor and reducing energy consumption in disguise.

[0004] However, the above-mentioned prior art still has some defects when it comes to fine grinding and mixing of Chinese medicinal materials: 1. The above-mentioned prior art sets semicircular gears and intermittent gears to drive the grinding bucket to swing back and forth, thereby increasing the grinding range of the grinding head and reducing the grinding dead angle. However, in actual use, when crushing some larger Chinese medicinal materials, they cannot be fully ground and need to be pre-processed and cut into small sections, which still needs to be optimized.

[0005] 2. The above-mentioned prior art arranges a sleeve and a push rod. When the swing motor drives the grinding bucket to swing, the cooperation between the push rod and the stop block is utilized to reduce the work done by the swing motor and reduce energy consumption. However, in actual use, if a large amount of Chinese medicinal materials need to be crushed, since the volume of the grinding bucket is fixed, it is necessary to put the Chinese medicinal materials into the grinding bucket and take the crushed Chinese medicinal materials out of the grinding bucket many times, which is relatively cumbersome.
