Feed crushing device with dust recycling function

Abstract

The invention provides a feed crushing device with a dust recycling function and belongs to the field of crushing devices. The feed crushing device comprises a small-particle collection device, a funnel-shaped collection device, a vibration device, a secondary-crushing and screening device, a disc cutting device, a feeding device and transmission devices. The first transmission device and the second transmission device are arranged inside a transmission device storing cavity, and the secondary-crushing and screening device, a slope-type screen, the funnel-shaped collection device and the small-particle collection device are arranged inside a crushing and screening cavity. Compared with a common crusher, by arranging the multi-stage crushing device and an arc-shaped screen, the crushing speed can be increased, and meanwhile the feed crushing effect is improved; by arranging the slope-type screen and the vibration device, small particles and dust which are contained in crushed feed can be well filtered away; and through the arranged small-particle collection device on the lower portion, the dust feed in air is filtered and collected, and thus resource waste is reduced.

Description

technical field [0001] The invention relates to a crushing device, in particular to a feed crushing device with dust recovery function. Background technique [0002] At present, after the feed is cooled and dried by the granulator, the particles are generally relatively large, and the chicks cannot peck. Therefore, according to the requirements of different animal foraging habits and growth stages, it needs to be broken into different particle sizes; but in the prior art , most of the crushers are composed of double crushing wheels, and the feed is crushed through the extrusion between the two crushing wheels. Through this traditional crushing method, a good crushing effect cannot be achieved, and the size is uneven, and the crushing rate Low cost, cumbersome operation, and the crushed feed has to be screened by an external vibrating screen. The operation is cumbersome. Due to uneven crushing, the crushed particles are uneven in size, and there is no dust collection device, ...

[0002] At present, after the feed is cooled and dried by the granulator, the particles are generally relatively large, and the chicks cannot peck. Therefore, according to the requirements of different animal foraging habits and growth stages, it needs to be broken into different particle sizes; but in the prior art , most of the crushers are composed of double crushing wheels, and the feed is crushed through the extrusion between the two crushing wheels. Through this traditional crushing method, a good crushing effect cannot be achieved, and the size is uneven, and the crushing rate Low cost, cumbersome operation, and the crushed feed has to be screened by an external vibrating screen. The operation is cumbersome. Due to uneven crushing, the size of the crushed particles is uneven, and there is no dust collection device, resulting in waste of resources.
