Dust suppression device for combined harvester and combined harvester with dust suppression device

Abstract

The invention discloses a dust suppression device for a combined harvester and the combined harvester with the dust suppression device. The dust suppression device comprises a shell and a spraying assembly connected with the shell, wherein the shell is provided with a dust inlet and a dust suppression hole; spraying water ejected from the spraying assembly is mixed with dust sent into the shell through the dust inlet and is discharged out of the shell through the dust suppression hole; ans the spraying assembly comprises a water tank, a pressure pump, a water pipe, at least two branched pipesand a plurality of spraying holes, the pressure pump and the water pipe are connected with the water tank, the branched pipes are arranged in the shell at intervals and are connected with the water pipe, and the spraying holes are distributed in the surfaces of the branched pipes at intervals. By arranging the dust suppression device, dust in a conveying slot and raising dust on the side of an engine are adsorbed and suppressed and are combined with water mist to form muddy drops, and the muddy drops fall to the ground, so that pollution of the raising dust, shortening of the service life of equipment and damage of the health of an operator are avoided.

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.
