Description

Technical Field

[0001] The utility model belongs to the improvement of the picking head structure of a cotton picker, in particular to an improved picking head of a cotton picker. Background Art

[0002] Cotton picking is the operation with the greatest labor intensity, the most labor input and the longest construction period in cotton production. With the in-depth development of agricultural mechanization, mechanized cotton picking is an inevitable trend in the cotton industry. A cotton picker is an essential agricultural equipment for cotton picking, which has the advantages of high cotton picking efficiency, reduced labor intensity and saved labor costs. During the cotton picking process of the existing cotton picker, the whole cotton plant enters the inside of the picking head through a guide plate, and the cotton stalks are close to the long bars. The driving gear drives the seat tube spindles to rotate counterclockwise backward. During the rotation process, broken cotton stalks and cotton fruiting branches are inevitably generated and enter the inside of the picking head through the gaps between the long bars, causing blockage, thereby reducing the picking efficiency and the picking rate. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an improved picking head of a cotton picker, which has a reasonable structure and can secondarily prevent broken cotton stalks and cotton fruiting branches from entering the inside of the picking head, reduce the blockage rate, effectively improve the operation progress of the cotton picker, and improve the picking efficiency and the picking rate.

[0004] The purpose of the utility model is realized as follows: an improved picking head of a cotton picker includes a cotton picking head unit composed of evenly distributed picking heads arranged at the front of the cotton picker. Two parallel guide plates are fixedly installed on the inlet provided at the front end of the picking head. A seat tube driven by gears is arranged inside the picking head frame. Spindles are evenly arranged on the seat tube. Arc-shaped long bars are horizontally arranged from top to bottom in sequence. The gaps formed by the long bars cooperate with the evenly distributed spindles. An upright support rod is arranged on the picking head frame behind the seat tube. Arc-shaped comb teeth are horizontally arranged from top to bottom in sequence on the support rod. The comb teeth point to the front of the seat tube. The evenly distributed comb teeth correspond to the evenly distributed long bars one by one.

[0005] The utility model can secondarily prevent broken cotton stalks and cotton fruiting branches from entering the inside of the picking head by adding bars, reduce the blockage rate and effectively improve the operation progress of the cotton picker.

[0006] The utility model has a reasonable structure, realizes secondarily preventing broken cotton stalks and cotton fruiting branches from entering the inside of the picking head, reduces the blockage rate, effectively improves the operation progress of the cotton picker, and improves the picking efficiency and the picking rate. Brief Description of the Drawings

[0007] The following will further describe the utility model with reference to the drawings. Figure 1 is the overall structural schematic diagram of the utility model. Figure 2 is the structural schematic diagram of the picking head.Figure 3 is Figure 2 a top view structural schematic diagram of Figure 4 the comb tooth mounting structure Specific embodiments

[0008] The cotton picking head of an improved cotton picker, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , includes a cotton color head unit composed of evenly distributed cotton picking heads 2 arranged at the front of the cotton picker 1. Two parallel guide plates 3 are fixedly installed on the inlet at the front end of the cotton picking head 2. A seat tube 6 driven by a gear 5 is arranged in the cotton picking head frame 4. Spindle pickers 7 are evenly arranged on the seat tube 6. Arc-shaped long grid bars 8 are horizontally arranged in sequence from top to bottom. The gaps formed by the long grid bars 8 cooperate with the evenly distributed spindle pickers 7. An upright support rod 9 is arranged on the cotton picking head frame 4 behind the seat tube 6. Arc-shaped comb teeth 10 are horizontally arranged in sequence from top to bottom on the support rod 9. The comb teeth 10 point to the front of the seat tube 6. The evenly distributed comb teeth 10 correspond to the evenly distributed long grid bars 8 one by one. The arc radian of the comb teeth 10 is the same as that of the long grid bars 8. The tips of the comb teeth 10 correspond to and cooperate with the ends of the long grid bars 8. The evenly distributed comb teeth 10 are respectively fixedly connected to the support rod 9 through bolts 11.
