Description

Technical Field

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

[0002] Cotton picking is the most labor-intensive, labor-intensive, and time-consuming operation in cotton production. With the increasing development of agricultural mechanization, mechanized cotton picking is an inevitable trend in the cotton industry. Cotton pickers are essential agricultural equipment for cotton picking, offering advantages such as high cotton picking efficiency, reduced labor intensity, and reduced labor costs. Traditional cotton pickers have a set of air ducts and two air outlets arranged in a straight line. The front air outlet blows the cotton far from the cotton conveyor pipe, which easily disperses the wind force, reducing picking efficiency and cleanup rate. Utility Model Content

[0003] The purpose of the utility model is to provide an improved cotton wind conveying system of the cotton picking head unit of the cotton picker, which has a reasonable structure and can increase the cotton blowing wind force of the traditional cotton picker picking head, reduce the blockage of cotton in the picking head, and effectively improve the working efficiency and operating area of the cotton picker.

[0004] The purpose of the present utility model is achieved as follows: an improved cotton pneumatic conveying system of the cotton picking head group of a cotton picker, including a cotton picking head group composed of uniformly distributed picking heads arranged at the front of the cotton picker, the cotton picking head group consisting of a first picking head and a second picking head, each group of cotton picking head groups is respectively provided with a cotton conveying pipe and an air duct, a third picking head is arranged in front of the second picking head of the cotton picking head group, an upright additional air duct matched with the third picking head is arranged in the third picking head box, the lower end of the additional air duct corresponds to the pipe end of the horizontally arranged cotton conveying pipe, the upper end of the additional air duct extending from the top of the third picking head box is connected to the connecting pipe, and the inlet of the connecting pipe is connected to the corresponding air duct through a joint pipe.

[0005] This utility model increases the wind force of cotton transport by adding a cotton picker head, air duct, and connecting pipe. The cotton transport pipe concentrates wind force to transport cotton, effectively increasing the wind force of cotton transport from the traditional cotton picker head and reducing cotton blockage. This effectively improves the efficiency and operating area of the cotton picker.

[0006] The utility model has a reasonable structure, increases the wind force for blowing cotton from the picking head of the traditional cotton picker, reduces the blockage of the picking head by cotton, and effectively improves the working efficiency and operating area of the cotton picker. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The present invention will be further described below with reference to the accompanying drawings. Figure 1 This is a schematic diagram of the main structure of the utility model. Figure 2It is a schematic diagram of the three-dimensional structure of the utility model. DETAILED DESCRIPTION

[0008] An improved cotton pneumatic conveying system for a cotton picking head unit of a cotton picker, such as Figure 1 、 Figure 2 As shown, a cotton picking head unit consisting of evenly distributed picking heads is arranged at the front of the cotton picking machine, and the cotton picking head unit consists of a first picking head 1 and a second picking head 2. Each group of cotton picking head units is respectively provided with a cotton conveying pipe 4 and an air duct 5. A third picking head 3 is arranged in front of the second picking head 2 of the cotton picking head unit. An upright additional air duct 6 is arranged in the third picking head box to match the third picking head 3. The lower end of the additional air duct 6 corresponds to the pipe end of the horizontally arranged cotton conveying pipe 4. The upper end of the additional air duct 6 extending from the top of the third picking head box is connected to a connecting pipe, and the inlet of the connecting pipe is connected to the corresponding air duct 5 through a joint pipe 7. The structure of the joint pipe 7 is that one end of the transverse seat pipe is closed and the other end is open. A pipe interface is provided on the pipe wall of the transverse seat pipe. The pipe interface of the transverse seat pipe is connected to the connecting pipe of the additional air duct 6. The other end opening of the transverse seat pipe is connected to the air duct 5.
