Description

Machine for picking cotton falling to ground

Technical Field

The utility model relates to a ground cotton picking machine, and belongs to cotton picking equipment.

Background

Most cotton growers use cotton pickers to harvest cotton at present, but the recovery ratio of the cotton pickers is mostly 60-70%, a lot of cotton bolls are not harvested, and a lot of cotton falls to the ground, so that great waste is caused. Previously, these mechanical cotton harvesting operations were performed manually, which was very laborious and slow. In order to solve the problem of harvesting the fallen cotton, the fallen cotton picker with the publication number of CN213960829U discloses a structure, which comprises a cotton brushing mechanism and a negative pressure collecting bin, wherein cotton collected by the cotton brushing mechanism is sucked into the negative pressure collecting bin through a cotton sucking pipe arranged on the negative pressure collecting bin, the device has a simple structure, but the impurity content of the cotton picked is too high. The notice number is: the CN214102380U fallen cotton picker discloses another structure, the device is provided with a cotton impurity removing mechanism, but the impurity removing mechanism is composed of four groups of impurity removing rollers, so the structure is too complex, the working speed is slow, and the device is not suitable for the high-efficiency fallen cotton picking operation in cotton fields after practical use. The notice number is: CN 209283763U's utility model discloses a machine is adopted cotton ground and is picked up separating centrifuge with cotton that falls to ground, including the frame, be provided with in the frame and pick up cotton device, pipeline, fan and drive arrangement, wherein pick up cotton device and include front roll, cylinder, compress tightly the brush, clap the sediment pole and clean the brush. When the cotton boll picking machine works, the driving device drives all the parts to work, the front roller digs the cotton dropped to the position of the roller, the compressing brush compresses the cotton bolls to the position of the roller, the roller rotates to drive the cotton bolls to rotate to the position of the cotton boll beating rod, the cotton boll beating rod stirs the cotton boll shells, cotton flowers in the cotton bolls can be hooked out due to the saw teeth arranged on the roller, the cotton bolls are not beaten by the cotton beating rod, and only the cotton hulls can be blocked, so that the aim of separating the cotton from the cotton hulls is fulfilled; cleaning the brush and brushing the cotton on the roller into the pipeline; under the action of the fan, cotton entering the pipeline is sucked into a trailer behind the pipeline for storage. The mechanism has the problem that a large amount of cotton is wound and wrapped, and the machine is easy to malfunction. Through retrieval, the problems of low processing speed, high impurity content and unreasonable mechanism arrangement after the fallen cotton is picked up commonly exist in the existing fallen cotton picking machine.
