Feed screening device with multi-stage classification and screening method

Abstract

The invention discloses a feed screening device with multi-stage classification and a screening method. The feed screening device comprises a box body, wherein a collecting frame is movably connectedto the bottom of an inner cavity of the box body, a protective shell is fixedly connected to the left side of the box body, a mounting plate is fixedly connected to the position, located at the bottomof an inner cavity of the protective shell, of the left side of the box body, and a gear motor is fixedly connected to the top of the mounting plate. According to the feed screening device, through cooperative use of the box body, a third screen, fixed shells, buffer springs, flow guide plates, a second screen, extendable rods, a movable frame, a feeding hopper, a first screen, fixing plates, a movable rod, a movable sleeve, a fixing column, a rotary disc, the gear motor and the collecting frame, the problem that an existing feed screening device is generally primary or secondary screening, the screening effect is poor, and during screening, feed cannot be rapidly classified into particles with different sizes, so that the preparation efficiency of the feed with different sizes is reduced, and the feed is inconvenient to take out rapidly after screening is completed is solved.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a multi-level classification feed screening device and screening method. Background technique [0002] Pig feed is usually a feed for raising domestic pigs composed of protein feed, energy feed, roughage, green feed, silage, mineral feed and feed additives, classified by category: full price feed, concentrate feed and premix, full price The feed is a batch composed of four parts: protein feed, energy feed, roughage and additives. The full-price feed sold on the market is mainly granular feed that has been machine-processed and granulated, and some are extruded pellets, which can be directly used for feeding. The feeding object can fully meet the nutritional needs of the feeding object. The concentrated feed is pre-mixed with protein raw materials and additives. When feeding, energy feed needs to be added. It has the advantage of easy use and is suitable for large-scale, e...

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-stage classification feed screening device and screening method, which has the advantage of multi-stage classification and screening, and solves the problem that the existing feed screening devices usually use one-stage or two-stage screening, and the screening effect is not good. Well, the feed cannot be quickly sorted into particles of different sizes during screening, which reduces the preparation efficiency of feed of different sizes, and it is inconvenient to quickly take it out after the screening is completed
