Fine feed grinding device for fry breeding

Abstract

The invention discloses a feed fine grinding device for fish fry cultivation, which comprises a shock absorbing spring, a shock absorbing cylinder, a grinding box, a grinding tank, a screening plate, a screw rod, a grinding roller, a grinding motor, a feeding trough, and a quantitative circular wheel and a magnet, the inside of the grinding box is provided with a grinding tank, a sieve plate is installed at the bottom of the grinding tank, a screw rod is installed on the front side of the grinding tank, and a guide rod is fixedly installed on the rear side of the grinding tank. Grinding rollers are also fixedly installed, and a quantitative round wheel is also rotatably installed inside the cutting trough; a magnet is fixedly installed on the lower side of the grinding box, and an electromagnet is also fixedly installed on the base. When it is necessary to grind the fish feed, the electromagnet is powered on and off intermittently, so that the grinding box moves up and down, thereby speeding up the speed of sieving the feed after grinding; after the sieving is completed, it is realized under the action of the quantitative round wheel Quantitative discharge, so as to accurately control the feeding amount of fish food, so as to achieve reasonable feeding.

Description

technical field [0001] The invention relates to a grinding device, in particular to a feed fine grinding device for fry cultivation. Background technique [0002] Fry is a juvenile fish that has just hatched, and the general body length is 6-9 mm. Because the fry are small in size, they need to grind the fish food and feed when feeding, so as to speed up the digestion of fish food by the fry. However, the existing fish food Insufficient grinding will occur in the grinding device. At the same time, when the feed is sieved after grinding, the sieve holes will often be blocked by the feed, resulting in sieving efficiency. Moreover, quantitative discharge cannot be achieved after sieving, resulting in the feeding of fry. Quantitative feeding cannot be done, which will affect the growth of fry. Contents of the invention [0003] The object of the present invention is to provide a feed fine grinding device for fish fry cultivation, so as to solve the problems raised in the abov...
