Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesters, in particular to a novel conveying auger cleaning housing structure, a cleaning device and a corn harvester. Background Art

[0002] As a major food crop, corn has a wide planting area in various regions of our country, with a cumulative planting area of about 35 million hectares across the country. To ensure food security, the whole country attaches great importance to agriculture and grain production. Grain harvesting is the hard-won result of months of labor by farmers, and every grain should be returned to the granary. However, at present, the basic cleaning method of the mainstream corn harvester models in the Central Plains is auger cleaning. During the cleaning process, the grains are discharged by the auger together with the husks and are lost in the field; since the cleaning principles of each manufacturer are the same and the cleaning structures are similar, the cleaning effects are not very different.

[0003] To further increase the corn yield and reduce the losses during harvesting, it is necessary to improve the cleaning principle or optimize the cleaning structure to enhance the cleaning effect and reduce the grain loss. Summary of the Utility Model

[0071] The working principle of the present utility model is as follows:

[0072] During the cleaning process, the corn to be cleaned falls from the upper end of the housing 1 into the housing 1. Conveyor augers are installed at the part of the housing 1 corresponding to the upper part of the sieve plate 2 and the lower part of the side plate 3. During the process of the corn falling from the upper end of the housing 1, some corn kernels fall through the sieve holes on the side plate 3 and the sieve plate 2 to the bottom of the housing 1, and then fall out of the housing 1 through the sieve holes at the bottom of the housing 1, completing the cleaning operation of the corn.

[0073] In addition, the corn kernels that fall through the sieve holes on the side plate 3 fall down through the guide plate 4.

[0074] The cleaning housing structure provided by the present utility model can separate the husks and kernels as much as possible by increasing the cleaning area, so that the husks are pushed out of the machine body, and the kernels enter the recovery device for recovery.

[0075] The solution in this scheme is a novel conveyor auger cleaning housing structure. By adding cleaning sieve holes on the middle partition and designing a partition structure at the same time, the husk and kernel are separated during the falling process of the husk, and then the separated kernels are recovered. The cleaning area is increased, and thus the cleaning effect is enhanced.

[0076] The advantages of the cleaning housing structure provided by the present utility model are as follows: improving the separation effect of the husks and kernels, increasing the user's income, and enhancing the competitiveness of the company's products and user satisfaction.
