Description

Technical Field

[0001] The utility model relates to the technical field of corn processing equipment, in particular to a corn cob threshing device. Background Art

[0002] After corn is harvested, threshing equipment is needed to separate the corn kernels on the mature corn cobs from the corn cobs to improve corn processing efficiency and facilitate subsequent processing of the corn kernels.

[0003] In the prior art, there is a corn cob threshing barrel and threshing equipment with announcement number CN220274310U, which includes a mounting barrel, which is hollow and has two sets of slide rails fixedly connected to the outer wall of the mounting barrel, each set of slide rails is provided with a plurality of slide rails, and the plurality of slide rails are fixed on the mounting barrel in a circular array; a slide bar, which has a slide groove, and the slide bar is slidably connected to the mounting barrel through the slide groove and the slide rail; the scheme forces the push rod to drive the slide bar to reciprocate on the slide rail through a wave ring, and the reciprocating slide bar will drive the rubbing block to move back and forth, at which time the rubbing blocks on the adjacent slide bars can clamp the corn cob and efficiently rub off the corn kernels on the corn cob.

[0004] However, the above scheme still has some shortcomings. For example, when threshing corn cobs, corn can only be threshed on one side. Since the corn cobs are of different sizes, the contact effect between some smaller corn cobs and the rubbing blocks is poor, resulting in corn kernels still existing on some corn cobs, causing incomplete threshing of the corn cobs and the inability to effectively complete the threshing process. In view of this, the utility model proposes a corn cob threshing device. Utility Model Content
