A dust suppression device for a combine harvester and a combine harvester with the same

Abstract

The invention discloses a dust reduction device of a combine harvester and a combine harvester with the device. The dust reduction device includes a casing and a spray assembly connected with the casing; the casing is provided with a dust inlet and the dust outlet; wherein, the spray water sprayed by the spray assembly is mixed with the dust sent into the housing by the dust inlet, and then discharged from the housing from the dust outlet; the spray The assembly includes a water tank, a booster pump and a water pipe connected to the water tank; at least two branch pipes are arranged at intervals inside the housing and connected to the water pipe; several spray holes are distributed at intervals on the surface of the pipe. The present invention realizes the adsorption and dust reduction of the dust in the conveying trough and the flying dust on the engine side by setting the dust reducing device, and combines the water mist with the dust and flying dust to form muddy water droplets, which fall to the ground, avoiding dust pollution, and causing Reduced equipment life and damage to the health of operators.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a dust suppression device of a combine harvester and a combine harvester equipped with the device. Background technique [0002] During the harvesting process of the combine harvester, a large amount of floating soil on the ground and dust on the crops enter the harvester together with the grain. When passing through the cleaning system, under the action of the cleaning fan, a large amount of dust is blown out, resulting in serious dust emission during the operation of the harvester. It is not conducive to environmental protection and green production; the driver is in the dust environment for a long time and affects the driver's health; a large amount of dust accumulates on the filter of the engine cooling fan, which will greatly affect the heat dissipation of the engine and affect the life of the harvester. [0003] The Chinese patent with the applica...

Problems solved by technology

[0005] Although the above-mentioned prior art has proposed a dust removal system for the harvester, the above-mentioned technical solution has not been able to solve the problem of dust raising in the conveying trough and dust collection around the engine, and the dust is separated from the device body in the process of dust removal. , and there is no physical dust reduction solution. Although the dust raising and dust collection problems of the harvester have been solved to a certain extent, it still pollutes the surrounding environment and cannot solve the above technical problems well.
