Corn threshing machine

Abstract

The invention discloses a corn threshing machine which comprises a machine frame and a cylindrical shell. A rotating shaft driven by external power is arranged in the shell. Corn stirring strips are axially arranged on the outer surface of the rotating shaft. One side of the rotating shaft coaxially drives a main belt wheel. An inlet and an outlet are formed in the same side of the upper portion of the shell and are next to each other in the vertical direction. A blocking piece located in the shell is arranged between the inlet and the outlet. A main conveying belt wheel is arranged at the position of the inlet and is coaxially driven by an auxiliary belt wheel on one side of the main conveying belt wheel. The auxiliary belt wheel is connected with the main belt wheel through a belt. One end of a conveying belt is sleeved with the main conveying belt wheel. The portion, away from the inlet, of the other end of the conveying belt is arranged on an auxiliary conveying belt wheel arranged on the machine frame in a sleeving mode. The lower end of the shell is mainly composed of a plurality of columnar threshing rods, and gaps for corn kernels to pass through are reserved between the threshing rods. The corn threshing machine is reasonable in design, capable of achieving rapid corn threshing and high in threshing efficiency; meanwhile, the corn threshing machine is simple in structure, low in manufacturing cost and suitable for application and popularization in villages.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a corn thresher. Background technique [0002] Threshing of sun-dried corn has long been a problem in rural production. The traditional method needs to rely entirely on manual operation, using simple tools or directly separating the corn kernels from the corn cob, although the integrity of the corn kernels is well preserved, it is time-consuming and inefficient. The threshing machine that is driven by diesel engine or electric motor is mostly used to carry out threshing process now, and the internal structure of existing threshing machine is complicated, volume is big, and price is more expensive, is unfavorable for promoting and realizing the mechanization of agricultural production. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a corn thresher with simple structure, small volume and high working efficiency...

Problems solved by technology

The traditional method needs to rely entirely on manual operation, using simple tools or directly to separate the corn kernels from the corn cob, although the integrity of the corn kernels is well preserved, it is time-consuming and inefficient

Nowadays, threshers driven by diesel engines or electric motors are often used for threshing, but the existing threshers have complex internal structures, large volumes, and high prices, which are not conducive to the promotion and realization of mechanization of agricultural production.
