Description

Technical Field

[0001] The utility model belongs to the field of cotton picker accessories, in particular to a picking spindle for a cotton picker. Background Art

[0002] When cotton crops are planted on a large scale, in order to save manpower and improve picking efficiency, cotton pickers are often used to separate cotton from cotton stalks through picking spindles. Some existing picking spindles are integrated structures, that is, the picking rod and the bevel gear are installed in one piece. When the cotton picker works for a long time, the picking teeth on the picking rod may break or be severely worn, and the bevel gear may also be severely worn. Any of these problems requires the replacement of the entire picking spindle, which results in a waste of cost and materials; of course, some picking spindles are split structures, that is, the bevel gear and the picking rod are connected together through bearings and connecting seats and other parts. This structure requires the addition of lubricating oil to rotate smoothly. All the picking spindles on the cotton picker need to be lubricated one by one, which is cumbersome to operate and has a high production cost. Utility Model Content
