Description

A dust reduction device for peanut harvester

technical field

The invention relates to the field of dust reduction equipment, in particular to a dust reduction device for a peanut harvester.

Background technique

The peanut harvester will bring a lot of dust in the working process, affecting the sight of the staff, polluting the environment, and the dust will damage the respiratory system after being inhaled by the human body. Therefore, the peanut harvester needs to be equipped with a dust reduction device.

The Chinese invention patent application with publication number CN110302627A discloses a dust removal device for a peanut harvester, including a dust removal grass box, a dust removal fan and a dust collector. The top of the straw box is provided with a dust removal fan, the dust collector is connected with the air inlet of the dust removal fan through the air outlet pipe, and the air outlet of the dust removal fan is connected with the dust removal bag. The discharged air containing a large amount of dust enters the dust removal straw box and then enters the dust removal device through the air inlet. The filtered clean gas is discharged into the atmosphere through the dust removal bag at the rear of the dust removal device, and the dust reduction effect is good. It is necessary to remove the dust bag frequently and pour out the dust accumulated inside, which is inconvenient to use, and the dust bag is easily blocked, and the wind blown by the fan cannot be discharged in time, which affects the normal operation of the peanut harvester.

The Chinese utility model patent with publication number CN207410776U discloses a self-propelled peanut harvester, which includes a harvester main body, and the harvester main body includes a conveying mechanism box. The conveying mechanism box is provided with a conveying fan connected to a straw collection box. A dust removal air duct is arranged at the outlet of the fan, and the dust removal air duct is arranged along the outer wall of the straw collection box; the interface between the dust removal air duct and the conveying fan is provided with a straw mesh plate, and the straw mesh plate corresponds to the entrance of the straw collection box. The dust removal air duct includes a transverse section located above the straw collection box and a vertical section arranged at the side of the straw collection box, and the air outlet of the transverse section is communicated with the air inlet of the vertical section. The inner wall of the transverse section is arranged with a horizontal spray pipe, and the air outlet of the transverse section is provided with a vertically arranged fender, which has a certain dust reduction effect, but there is no dust reduction effect when no water is added, so it is necessary to supplement the spray in time. The required amount of water, because the peanut harvesting operation is usually outdoors, it is inconvenient to add water and troublesome to use, and the dust removal device has changed the structure of the peanut harvester, instead of being an independent dust removal device that can be installed later, it cannot be changed. There is a problem that the peanut harvester has a lot of dust.
