Description

Technical Field

[0001] The utility model relates to the technical field of feed processing, in particular to a pig feed crushing and grinding device. Background Art

[0002] Feed is a general term for food consumed by all animals. More narrowly, it refers primarily to food consumed by animals raised in agriculture or animal husbandry. Feed includes over ten types of feed ingredients, including soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, additives, whey powder, oils, meat and bone meal, grains, and sweet sorghum. In the livestock industry, feed ingredients must be crushed and ground to produce smaller particles for livestock consumption.

[0004] However, the above scheme does not provide a feed raw material screening structure. During the actual feed raw material crushing and grinding stage, the stones mixed in the feed raw materials (for example, soybeans, soybean meal, and corn all contain different proportions of stones) cause varying degrees of damage to the crushing tools and grinding mechanisms, resulting in a significant reduction in the service life of the feed raw material processing equipment.

[0005] To this end, a pig feed crushing and grinding device is proposed, which has the advantage of facilitating the removal of stones and impurities from feed raw materials, thereby solving the problems in the above-mentioned background technology. Utility Model Content

[0014] In the utility model, a blower, a feeding barrel, a discharge nozzle, an air inlet hood, a turnover hopper and a stone discharge port are arranged on the crushing box. Feed raw materials are fed into the feeding barrel and then the blower is started to work, so that the air duct at the air outlet of the blower blows air horizontally from the air inlet hood into the feeding barrel.

At the same time, the second motor is started to drive the grinding cone to rotate, causing the grinding cone to drive the second grinding surface and the third grinding surface of its annular surface to rotate. Since the inner ring of the grinding ring fixed to the outer periphery of the grinding cone is provided with the first grinding surface, and the gap between the first grinding surface and the second grinding surface is larger than the gap between the first grinding surface and the third grinding surface, the crushed feed raw materials can be subjected to secondary grinding processing. Compared with the existing technology, the arrangement of the scraping strips and the filter screen facilitates the filtering and screening of the feed raw materials in the crushing stage, and there is no need for secondary return material crushing. The arrangement of the first grinding surface, the second grinding surface and the third grinding surface achieves the effect of secondary grinding, thereby increasing the fineness and efficiency of the feed raw material processing.
