Description

Technical Field

[0001] The utility model belongs to the technical field of medicinal material processing, and in particular relates to a machine base for a traditional Chinese medicine pulverizer. Background Art

[0002] The pulverizer is an important equipment in the processing of Chinese herbal medicines. It mainly grinds block and root-shaped herbs into powder through high-speed rotating meshing gears. The high-speed rotating meshing gears need to provide large torque, high speed and long working time. Under such high temperature and high load conditions, the bearings on the transmission shaft and the base used for fixed assembly often break.

[0003] At present, the base of the crusher on the market will be equipped with a cooling device, which mainly cools the inside of the base by adding an interlayer on the outer wall of the base and passing chilled water inside the interlayer. However, if the outer wall is too thick, the cooling effect will be poor. If the outer wall is too thin, the base will be insufficiently rigid, which will cause deformation under heavy load.

[0004] Since Chinese medicinal materials are crushed, in order to prevent the equipment from being contaminated during the crushing process, the joints need to have a high degree of sealing. At present, most of the crushers on the market use labyrinth seals, dry gas seals combined with compressed air, packing seals, etc., but there are still problems with incomplete sealing. After long-term use, medicinal material powder enters the bearings and causes bearing damage, and some engine oil enters the powder, causing the powder to be contaminated. Summary of the invention

[0005] The utility model aims to provide a machine base for a traditional Chinese medicine pulverizer to solve the shortcomings of the existing pulverizer machine base in terms of cooling and sealing.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a machine base for a Chinese medicine pulverizer, comprising a machine base, a transmission shaft, a meshing gear, a fixing component, a sealing end cover, a bearing and a bottom cover plate;

[0007] The base is a hollow cylindrical structure, a circular water channel is provided inside the side wall, and a water inlet and a water outlet connected to the circular water channel are provided on the side wall;
