Vertical spindle type cotton picking head

Abstract

The utility model relates to a vertical spindle type cotton picking head, which is used for picking and collecting cotton and consists of a main shaft, an upper bearing, a belt pulley, an external belt, a hollow shaft, a pattern plate cylinder, cotton picking knives, a base, a lower bearing, an upper disc and an internal belt, and the clamping hooks are in clearance fit with grooves formed in the outer surface of the hollow shaft to form a plurality of vertical picking spindles for cotton picking and cotton doffing. Due to the characteristic of high-strength winding of cotton, the cotton fibers can be easily wound on the body of the cotton picking spindle by matching with the rotation speed of the zigzag clamping hooks on the vertical picking spindle, and meanwhile, the falling and re-picking of the cotton are realized along with the revolution speed of turning of the vertical picking spindle. Due to the detachability and the replaceability of the cotton picking cutter, the technical bottleneck of a domestic cotton picker is broken through, the manufacturing cost and the maintenance cost are reduced, and the economic cost of agricultural mechanization is greatly reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of picking spindles and picking cotton, in particular to a vertical picking spindle type cotton picking head. Background Art

[0002] As an important cash crop, cotton not only plays an important role in agricultural production, but also has a wide range of applications in textiles, medicine, chemical industry and other fields. It is one of the indispensable strategic crops in my country. In order to replace the traditional manual cotton picking, improve the efficiency of cotton picking, improve agricultural production technology and economic benefits, and achieve the strategic goal of agricultural mechanization in my country, my country has introduced a large number of foreign cotton pickers. The cotton pickers mainly from John Deere and Case are expensive and have high maintenance costs. They are all horizontal spindle pickers. In addition, the horizontal spindles are more destructive to cotton wool when running at high speed, and secondary cotton picking cannot be performed.

[0003] The cotton picking head is the core part of the cotton picker, and its performance directly determines the working efficiency and cotton yield of the cotton picker. However, the existing cotton picking heads are expensive, complicated to maintain, and have a low picking rate. The utility model aims to design a new vertical spindle-type cotton picking head which is low in cost, easy to maintain, and has a high picking rate. Utility Model Content

[0017] The principles and features of the present invention are described below in conjunction with the following drawings, and the examples given are only used to explain the present invention.

[0018] like Figures 1 to 3 In the example shown, a vertical spindle-type cotton picking head is provided in this embodiment. The utility model comprises a main shaft 1, an upper bearing 2, a pulley 3, an external belt 4, a hollow shaft 5, a flower plate tube 6, a cotton picking knife 7, a base 8, a lower bearing 9, an upper plate 10 and an internal belt 11. The vertical spindle-type cotton picking head is stably fixed by its upper bearing 2 and lower bearing 9. The main shaft 1 is interference-fitted with the upper bearing 2 and the lower bearing 9. The upper end of the main shaft 1 is fixedly connected to the center hole-type upper plate 10, and its lower end is fixedly connected to the base 8. The upper plate 10 is clearance-fitted with the lower surface of the pulley 3. The pulley 3 is fixedly connected to the hollow shaft 5. The outer surface of the hollow shaft 5 is clearance-fitted with the inner surface of the cotton picking knife 7. The lower end of the hollow shaft 5 is clearance-fitted with the base 8. The flower plate tube 6 is fixed between the base 8 and the upper plate 10. The outer surface of the internal belt 11 and the inner surface of the external belt 4 are clearance-fitted with the groove of the pulley 3.

[0019] The twelve cotton picking knives 7 are all provided with sawtooth hooks, and the hooks are clearance-matched with the grooves provided on the outer surface of the hollow shaft 5 .

[0020] The power source is transmitted to each connecting component by the rotation of the main shaft 1, so that the vertical picking spindle revolves around the main shaft 1.

[0021] The groove of the pulley 3 and the outer surface of the inner belt 11 rub against each other in the forward direction, while the groove of the pulley 3 and the inner surface of the outer belt 4 rub against each other in the reverse direction.

[0022] The ends of the external belt 4 and the internal belt 11 are connected to the cotton picking head frame.

[0023] The workflow of this embodiment is as follows:

[0024] When the cotton picker starts working, the power source applies counterclockwise rotational kinetic energy to the main shaft 1. This rotational kinetic energy is first transmitted through the main shaft 1 to the center hole-shaped upper plate 10 at its upper end and the base 8, thereby driving the entire flower plate tube 6 to revolve counterclockwise around the main shaft 1;

[0025] At the same time, the upper plate 10 drives the pulleys 3 evenly distributed around the flower plate tube 6 to rotate synchronously. The rotation of the pulley 3 further drives the hollow shaft 5 fixedly connected thereto to rotate. Due to the clearance fit between the outer surface of the hollow shaft 5 and the inner surface of the cotton picking knife 7, a plurality of vertical picking spindles are formed, and these vertical picking spindles revolve counterclockwise around the main shaft 1 as the hollow shaft 5 rotates;

[0026] During the revolution, the pulley 3 generates friction transmission with the inner belt 4 and the outer belt 5. Specifically, when the groove of the pulley 3 rubs against the outer surface of the inner belt 4, the pulley 3 rotates counterclockwise, thereby driving the sawtooth hook on the vertical picking spindle to wrap around the cotton, completing the cotton picking work;

[0027] Then, when the groove of the pulley 3 rubs against the inner surface of the external belt 5, the pulley 3 rotates clockwise. This change in the direction of rotation causes the sawtooth hook on the vertical picking spindle to change direction, thereby throwing off the entangled cotton and completing the cotton removal work;

[0028] After the cotton stripping is completed, the pulley 3 enters the friction transmission area with the inner belt 4 again, and starts a new round of counterclockwise rotation and cotton picking process. This cycle is repeated to achieve continuous and efficient cotton picking and stripping operations.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
