Multistage feed screening device and use method

Abstract

The invention discloses a multistage feed screening device and a use method. The multistage feed screening device comprises a screening box, the top of the screening box communicates with a crushing box, the tops of the two sides of the crushing box communicate with hoppers, the top of the crushing box is fixedly connected with a hydraulic telescopic rod, and the bottom of the output end of the hydraulic telescopic rod penetrates into an inner cavity of the crushing box to be fixedly connected with a shell. According to the multistage feed screening device and the use method, through the cooperation of a screening box, an opening, a metal net barrel, a third motor, a second housing, a discharge port, a discharge pipe, a receiving pipe, a water inlet valve, the crushing box, the hoppers, the hydraulic telescopic rod, a drain valve, a first motor, a crushing seat, a crushing roller, tap water, a shell, a guide plate, a vibration motor, a filter screen plate, a first rotating rod, a second rotating rod, a material turning roller, a material receiving box, a second belt wheel set, a second motor, a first belt wheel set, a first housing and inner spiral blades, the problems that an existing feed screening mode is a single-stage screening mode, the screening effect is poor, and the applicability is poor are solved.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a feed multi-stage screening device and a use method. Background technique [0002] Feed is the general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or animal husbandry. The feed includes soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives and more than ten varieties of feed materials. [0003] Feed is used in animal husbandry. In the process of feed processing, it is necessary to use screening devices to screen feeds of different sizes. However, the existing screening devices are single-stage screening methods. Therefore, the screening of feed The effect is poor and the screening efficiency is low. At the same time, the existing feed screening device does not have the function of crushing the ...
