Description

Technical Field

[0001] The utility model belongs to the improvement of the cotton picking head structure of a cotton picker, in particular to an improved cotton picking head unit 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. The cotton picking head of a traditional cotton picker uses two sets of cotton stripping disks at the front and back for cotton stripping. After cotton stripping, the cotton is sucked and conveyed by a common air duct group and enters the cotton storage box. During the process of sucking and conveying the cotton, since the cotton stripping disk at the front part of the cotton picking head is far from the air duct. Moreover, the front cotton stripping disk is farther than the rear one, and more cotton falls off, which easily causes cotton blockage, siltation and blockage between the front cotton stripping disk and the air duct, thus reducing the picking efficiency and cleaning rate. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an improved cotton picking head unit of a cotton picker, the structure of which is reasonable, and can reduce the siltation and blockage between the front cotton stripping disk and the air duct, and improve the cotton picking efficiency and cleaning rate.

[0004] The purpose of the utility model is realized as follows: An improved cotton picking head unit of a cotton picker includes a cotton picking head unit composed of evenly distributed cotton picking head groups arranged at the front part of the cotton picker. Each cotton picking head group consists of a first cotton picking head and a second cotton picking head. Each cotton picking head group is respectively provided with a first air suction and conveying duct. A seat pipe and a cotton stripping disk assembly are respectively arranged in the cotton picking head box of each cotton picking head. The spindles evenly arranged on the seat pipe are matched with the cotton stripping disks evenly arranged on the cotton stripping disk assembly. The transmission shaft drives the seat pipe and the cotton stripping disk assembly to rotate through a gear box. A third cotton picking head is arranged in front of the second cotton picking head of the cotton picking head group. Corresponding sprockets are respectively arranged on the driven wheels arranged between the gear boxes of the evenly distributed adjacent cotton picking head groups and on the driven wheels arranged between the gear boxes of the correspondingly evenly distributed adjacent first cotton picking heads. The gear box of the first cotton picking head is driven by a chain. The second air suction and conveying ducts respectively arranged on the evenly distributed first cotton picking head boxes are connected to the cotton storage box.

[0005] By adding a set of cotton picking heads, a set of cotton stripping disks and an air suction and conveying duct, the utility model effectively reduces the cotton suction and conveying distance between the cotton stripping disk and the air suction and conveying duct, and reduces the cotton blockage and siltation rate between the cotton stripping disk and the air suction and conveying duct. The cotton suction and conveying volume of the rear air suction and conveying duct is reduced, the cotton blockage and siltation rate between the rear cotton stripping disk and the air suction and conveying duct is effectively reduced, and the working progress of the cotton picker and the cleaning rate of cotton plants are effectively improved.

[0006] The structure of the utility model is reasonable, reducing the blockage and congestion of cotton between the front cotton stripping disc and the air duct, and improving the cotton picking efficiency and cleaning rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The present utility model will be further described below in conjunction with the drawings. Figure 1 It is a three-dimensional structure schematic diagram of the present utility model. Figure 2 It is Figure 1 an enlarged structure schematic diagram of a set of cotton picking heads. Figure 3 It is Figure 2 a top view structure schematic diagram. SPECIFIC EMBODIMENTS

[0008] An improved cotton picking head unit of a cotton picker, as shown in Figure 1 , Figure 2 , Figure 3 , includes a cotton picking head unit arranged at the front of the cotton picker and composed of evenly distributed cotton picking heads. The cotton picking head is composed of a first cotton picking head 3 and a second cotton picking head 2. Each group of cotton picking heads is respectively provided with a first air suction and conveying duct 4. A seat pipe 5 and a cotton stripping disc assembly 7 are respectively arranged in the cotton picking head box of each cotton picking head. The spindles 6 evenly arranged on the seat pipe 5 are matched with the cotton stripping discs evenly arranged on the cotton stripping disc assembly 7. The transmission shaft 11 drives the seat pipe 5 and the cotton stripping disc assembly 7 to rotate through a gear box 10. A third cotton picking head 1 is arranged in front of the second cotton picking head 2 of the cotton picking head group. Corresponding sprockets 14 are respectively arranged on a driven wheel 12 arranged between the gear boxes 10 of evenly distributed adjacent cotton picking heads and on a driven wheel 12 arranged between the gear boxes 10 of corresponding evenly distributed adjacent first cotton picking heads. The gear box 10 of the first cotton picking head is driven through a chain 13. Second air suction and conveying ducts 8 respectively arranged on the evenly distributed first cotton picking head boxes are connected to a storage bin 9. The cross-sectional area of the second air suction and conveying duct 8 is larger than the cross-sectional area of the first air suction and conveying duct 4. The outlet of the first air suction and conveying duct 4 is connected to the front end of the second air suction and conveying duct 8.
