Threshing is a difficult problem in traditional corn production, and manual threshing is not only a large workload, but also inefficient. With the continuous improvement of agricultural mechanization technology, thresher is widely used, the performance of the threshing machine with good quality is stable, the technology is mature, and the corn kernels after mechanical threshing are convenient for deep processing and storage, which effectively ensures the smooth progress of corn production. However, in the actual use of the corn thresher, due to the farmer's incomplete grasp of the mechanical principle and use method or the operation is not standardized, it is easy to have problems such as grain destruction, machine damage, low efficiency and even potential safety hazards, which affects the operation effect of the threshing machine, therefore, the standardized use of the corn thresher is an effective guarantee for the smooth progress of production.
Basic principle
The corn that can be threshed after harvest is fed by the artificial conveyor belt, the feeding entrance is located in the upper part of the whole machine, the corn after feeding enters the threshing chamber, because it is subjected to the rotation impact of the rotor and the drum, the grain will be peeled off in turn, and the thresher at this stage adopts the mode of multiple threshing to ensure the decontamination rate of the grain. After the corn grains are threshed, they are separated by the sieve holes, and the remaining corn husks and corn silk and other impurities are discharged under the action of the fan, and the grains can be automatically collected.
The main power device of the corn thresher is the motor, which drives the threshing drum and fan to run through the rotation of the motor, which can realize the work requirements of corn threshing, screening, impurity removal and collection. Under the continuous optimization of the mechanical structure, the corn thresher model produced at this stage is more compact and integrated, and the functions are rich and reasonable, which effectively realizes high efficiency and low energy consumption, and saves floor space, which is convenient for use in rural areas.
