Matched plastic film residue separation device for cotton picker

Abstract

The invention relates to a matched plastic film residue separation device for a cotton picker. The matched plastic film residue separation device comprises a separation chamber. A large net-shaped roller, a small net-shaped roller and an air-lock valve area arranged in the separation chamber. A cotton flow inlet, a plastic film residue outlet and a seed cotton outlet are arranged on the separation chamber. The large net-shaped roller and the small net-shaped roller are both of internal hollow structures, gauzes are arranged at the peripheries of outer layers of the net-shaped rollers, and the small net-shaped roller is arranged obliquely above the large net-shaped roller and close to the plastic film residue outlet. When the matched plastic film residue separation device works, the large net-shaped roller and the small net-shaped roller rotate in a counterclockwise mode. The air-lock valve structurally and mainly comprises a casing, an air-lock valve rotating shaft and a fan blade arranged on the air-lock valve rotating shaft. In an initial stage for picking cotton, sundries in seed cotton can be removed, so that a serial of related work procedure links of opening, removing residues and the like can be eliminated after seed cotton is harvested, and energy consumption is reduced. The device can greatly reduce sundry separation difficulty and is simple in structure, economical and practical.

Description

technical field [0001] The invention relates to a residual film separation device matched with a cotton picker. Background technique [0002] With the continuous expansion of the area of ​​machine-picked cotton in Xinjiang, the residual film and other foreign fibers of machine-picked seed cotton have become a major problem in cotton processing. However, the existing cotton picking machines do not have corresponding cleaning equipment, and the harvested cotton contains a large amount of foreign fibers such as residual film, and the existing organic cotton picking cleaning equipment cannot effectively remove residual film and other foreign fibers, and the existing seed cotton residual film separation equipment They are all aimed at the cotton processing link. Since cotton is mechanically picked for multiple transfers and stacked for compaction, resulting in subsequent separation, it is necessary to increase the opening link, the opening device, high power consumption, and the ...

Problems solved by technology

However, the existing cotton picking machines do not have corresponding cleaning equipment, and the harvested cotton contains a large amount of foreign fibers such as residual film, and the existing organic cotton picking cleaning equipment cannot effectively remove foreign fibers such as residual film, and the existing seed cotton residual film separation equipment They are all aimed at the cotton processing link. Since the cotton is mechanically picked for multiple transfers and stacked for compaction, resulting in subsequent separation, it is necessary to increase the opening link, the opening device, high power consumption, and the opening effect directly affects the subsequent separation of residual film. Effect

In addition, after multi-channel processing, the residual film is broken and increased, which increases the difficulty of separation. At present, machine-picked cotton processing mainly relies on manual sorting, which is labor-intensive, time-consuming and labor-intensive, and hinders the promotion of machine-picked cotton technology.
