Description

Technical Field

[0001] The utility model relates to a picker, in particular to a straw feed picker integrating multi-stage crushing and dust removal, and belongs to the technical field of straw feed processing. Background Art

[0002] Straw feed mainly refers to fiber feed made from crushed sweet sorghum, corn, reed, cotton and other straws. It is the main feed for ruminants. When processing straw feed, the straw needs to be picked up and collected, and then crushed. In other words, special picking and processing equipment is needed to process the straw.

[0003] In the prior art, a straw picker and a baler using the picker are disclosed in publication number CN216218878U, which are provided with a picking mechanism, a chopping mechanism, an auger mechanism, a throwing mechanism and a balancing mechanism. The chopping mechanism is used to chop the straw and transport it to the auger mechanism after secondary dust removal. The auger mechanism is used to transport the straw to the throwing mechanism after tertiary dust removal. The throwing mechanism is powered by the chopping mechanism and is used to throw the straw into the baling chamber after quaternary dust removal. The chopping device and the throwing device are improved, which effectively reduces the blockage of the picker. The probability of clogging is increased, the output of the spreading device is increased, and the working efficiency is significantly improved.
