Description

Technical Field

[0001] The utility model relates to the technical field of cotton pickers, in particular to cotton grabbing equipment of a mechanical cotton picker head. Background Art

[0002] The cotton picking head is the front end part of the cotton picker. It contains multiple cotton picking rollers and other related working parts, such as straw dividers, pressure plates, cotton removers, etc. These parts work together to pick cotton from the cotton plants and send it to the cotton box through a series of transfer and processing processes.

[0003] The utility model patent application document with the publication number of "CN203896759U" discloses a cotton grabbing mechanism of a mechanical cotton picking head, which is mainly composed of a cotton stripping comb plate, a nylon tow and a plastic tube. When the cotton picking head of the technical solution is working, the rotating cotton grabbing licker-in roller hooks the cotton into the cotton picking head when the nylon tow comes into contact with the cotton. The comb teeth of the cotton stripping comb plate are inserted between the nylon wire rings composed of adjacent nylon tows of the cotton grabbing licker-in roller, which can peel the cotton grabbed by the cotton grabbing licker-in roller off the cotton grabbing licker-in roller and enter the conveying area.

[0004] The cotton grasping mechanism of the mechanical cotton picking head disclosed in the above document has the following defects: the nylon bundle of the cotton grasping mechanism of the mechanical cotton picking head is planted inside the plastic tube. However, during the long picking process, the nylon bundle is easily affected by the outside world and wears out and loses its grasping effect. Since there is no disassembly structure between the nylon bundle and the plastic tube, it is inconvenient to replace the nylon bundle.

[0005] It can be seen from this that the cotton grabbing mechanism of the existing mechanical cotton picking head does not have a structure that is convenient for replacing the nylon tow, and it is necessary to improve the existing shortcomings and provide a cotton grabbing device for a mechanical cotton picking head.

[0029] The fixing assembly 6 also includes a support frame 606, and the two ends of the roller 4 are both equipped with support frames 606. The outer surface of the support frame 606 is provided with a circular hole, and a sliding rod 607 is slidably connected inside the circular hole. The outer surface of the sliding rod 607 is sleeved with a second spring 608, and one end of the sliding rod 607 is provided with an anti-slip block 609, and the other end of the sliding rod 607 is in contact with the outer surface of the limiting column 604. One end of the second spring 608 is installed on the outer surface of the anti-slip block 609, and the other end of the second spring 608 is installed on the outer surface of the support frame 606;

[0030] By pressing the anti-slip blocks 609 at both ends of the roller 4, the anti-slip blocks 609 push the slide bar 607 to move toward one end of the fixed plate 601, so that the limiting column 604 gradually disengages from the inside of the limiting hole. When the outer surface of the limiting column 604 is flush with the outer surface of the fixed plate 601, the fixed plate 601 and the roller 4 are canceled from the fixed installation. By pulling the fixed plate 601 outward, the fixed plate 601 is taken out of the placement groove 401, and the fixing of the installation tube 2 is canceled.
