Manual feed grinding device for household livestock breeding

Abstract

The invention discloses a manual feed grinding device for raising domestic livestock, which includes a base, a main support, a screw rod, a lifting block, a gear A, a grinding head, a gear B, a grinding box and a double-sided rack. The bearing is rotatably installed with a screw rod, and a lifting block is threaded on the screw rod, and a fixed shaft is fixedly welded on the lower side of the lifting block, and a grinding head is fixedly mounted on the lower end of the fixed shaft, and a gear B is fixedly mounted on the rotating shaft. A grinding box is fixedly installed on the fixed seat; the lifting block in this device moves downward to drive the grinding head down to cooperate with the rotating grinding box to grind the feed, which is more time-saving and labor-saving than manual grinding, and the grinding is more complete; by adjusting the handle The pulling distance can adjust the descending height of the lifting block and the downward pressure of the grinding head, so as to adjust the size of the feed particles after grinding, so as to meet the needs of livestock of different ages for feeding.

Description

technical field [0001] The invention relates to a grinding device, in particular to a manual grinding device for domestic livestock feed. Background technique [0002] The crushing and grinding of feed raw materials is a very important link in feed processing. Through crushing, the large total surface area of ​​raw material particles per unit mass can be increased, the solubility of feed nutrients in animal digestive juice can be increased, and the digestibility of animals can be improved. Smaller size is more conducive to animal digestion and absorption. At present, large-scale livestock breeding enterprises usually use large-scale grinding machines to grind livestock feed, but large-scale grinding machines are expensive and require a lot of electricity to maintain. Mechanical grinding is unrealistic. Feed is usually ground by hand, but the grinding speed is slow and the grinding effect is poor. At the same time, feed of different particle sizes cannot be ground according t...

[0002] The crushing and grinding of feed raw materials is a very important link in feed processing. Through crushing, the large total surface area of ​​raw material particles per unit mass can be increased, the solubility of feed nutrients in animal digestive juice can be increased, and the digestibility of animals can be improved. Smaller size is more conducive to animal digestion and absorption. At present, large-scale livestock breeding enterprises usually use large-scale grinding machines to grind livestock feed, but large-scale grinding machines are expensive and require a lot of electricity to maintain. For ordinary families, using large Mechanical grinding is unrealistic. Feed is usually ground manually, but the grinding speed is slow and the grinding effect is poor. At the same time, it is not possible to grind feed with different particle sizes according to livestock of different ages, which cannot meet the actual needs of the family.
