Corn threshing mechanism

Abstract

The invention discloses a corn threshing mechanism which comprises a rocker and a threshing cylinder. The threshing cylinder is in a hollow cylinder shape, one end of the threshing cylinder is an open part, the rocker is in an L shape, one arm of the rocker is a rotary shaft part, and the other arm of the rocker is a drive arm. The mechanism comprises a rack, a push plate, a fixed cone, a duplicate gear, a bevel gear, a milling cutter, an L-shaped support and a rotary shaft. The rack is connected with the threshing cylinder in a sliding mode, and the rack and the threshing cylinder are axially parallel. The fixed cone is fixed to the rack, points to the open part and is coaxial with the threshing cylinder. A straight tooth part of the duplicate gear is meshed with the rack, and a conical tooth part of the duplicate gear is meshed with the bevel gear. The rotary shaft part of the rocker is fixedly connected into a gear hole of the duplicate gear and is fixed to the threshing cylinder through a bearing. The rotary shaft is fixedly connected with the bevel gear and is fixed to the end face of the threshing cylinder through a bearing. The L-shaped support is located in the threshing cylinder, the short arm end of the L-shaped support is fixedly connected to the peripheral wall of the rotary shaft, the long arm end of the L-shaped support points to the open part, and the milling cutter is fixed to the front end of the long arm end. The corn threshing mechanism has the advantages of reducing labor intensity and improving efficiency.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a corn threshing mechanism. Background technique [0002] Corn is a very widely planted crop and is widely loved by people. In daily life, people often buy peeled corn kernels from the market as vegetables for cooking and eating. However, after corn cobs are picked from the field, How to peel off the corn kernels from the corn cob has always been a relatively difficult problem. Now most people use artificial methods to peel off the corn kernels one by one, which consumes a lot of manpower and is inefficient. [0003] In the prior art, there is a kind of household corn threshing mechanism, which includes a pedal, and a bracket is connected to the pedal. The top of the bracket is welded with a threshing cylinder, and a circular motion driven by a hand lever is arranged inside the cylinder. blade. [0004] When threshing corn, a person needs to hold one end of the corn cob, f...

Problems solved by technology

[0005] The above-mentioned mechanism uses the operator to fix the corn by hand, and also needs to manually change the direction of the corn, which is labor-intensive and low in efficiency; at the same time, when the corn cob is fed by hand, it may happen that the finger touches the scraper and is scratched. possibility of injury
