Description

Technical Field

[0001] The invention relates to the technical field of sorghum processing equipment, and in particular to a multi-stage grinding device for sorghum processing. Background Art

[0002] Sorghum is one of the important cereal crops cultivated by humans. It can be eaten, fed and brewed in daily life. At the same time, sorghum seeds also have the effects of strengthening the spleen and stopping diarrhea, resolving phlegm and calming the nerves. It is a crop with high comprehensive utilization value. The processing flow of sorghum is generally raw material cleaning, shelling and grinding. Among them, grinding is one of the important steps in the sorghum processing process. The degree of grinding of sorghum is one of the important factors affecting its quality and nutritional value. It also affects its steaming water absorption rate, volume expansion rate, cooking time and solid loss rate. In order to facilitate the processing and grinding of sorghum, a large number of processing equipment will be used, among which grinding equipment is one of the important processing equipment in sorghum processing. For example, the existing public document CN118751340A-A multi-stage grinding and crushing processing device for grain milling discloses a grinding device for multi-stage grinding of sorghum; The existing multi-stage sorghum grinding equipment mostly adopts relatively rotating moving grinding disc and static grinding disc to grind the sorghum, and the grinding of the sorghum is achieved by the contact friction between the steel teeth on the moving grinding disc and the static grinding disc and the sorghum. However, during the grinding process, part of the powdered sorghum will adhere to the steel teeth, and because the moving grinding disc is inside the equipment and the space is relatively narrow, it is not convenient to clean the steel teeth of the moving grinding disc, which will affect the subsequent multi-stage grinding of another batch of sorghum; in addition, due to the high-speed friction between the sorghum and the moving grinding disc and the static grinding disc, the temperature of the sorghum will increase, especially in the multi-stage grinding process, the heat will accumulate through multiple stages and cause the temperature of the ground sorghum to increase, thereby affecting its nutritional value; finally, the existing multi-stage sorghum grinding equipment mostly adopts a hopper for feeding, but due to the limited grinding space, it can only grind a certain amount of sorghum at a time, and the structure of the hopper is simple, and it is impossible to automatically feed the material in a certain amount, so the staff needs to manually feed the material in a certain amount; therefore, it is necessary to improve the existing technology to solve the above technical problems. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

When the multi-stage grinding device is in use, the driving rod 205 drives the movable grinding disc 202 in the outer shell 100 to rotate relative to the static grinding disc 203, thereby achieving the grinding of sorghum under the condition of relative rotation between the movable grinding disc 202 and the static grinding disc 203.

[0040] Specifically, a movable door 101 is hinged at the front end of the shell 100, and an ear seat 102 is welded on one side outer wall of the shell 100 and the movable door 101. A locking rod 103 is rotatably connected in the ear seat 102 on the shell 100. The front end of the locking rod 103 passes through the ear seat 102 on the movable door 101 and is threadedly sleeved with a butterfly nut 104. A discharge pipe 105 passes through the bottom of the shell 100, and the bottom end of the discharge pipe 105 is fixedly connected to a discharge cover 106. Three groups of grinding assemblies 200 are arranged at equal intervals from top to bottom inside the shell 100. The grinding assembly 200 includes a fixed plate 201 fixedly connected to the inner side of the shell 100, a moving grinding disc 202 rotatably connected to the front end of the fixed plate 201, a static grinding disc 203 fixedly connected to the movable door 101, and a screen 204 sleeved on the outer side of the moving grinding disc 202.
