Description

Technical Field

[0001] The utility model relates to the technical field of cotton picker manufacturing, in particular to a traction-type two-row cotton picker. Background Art

[0002] Cotton cultivation is widespread in my country. Previously, cotton picking relied primarily on manual labor, which was labor-intensive and inefficient. With the continuous improvement of agricultural mechanization in my country, the development of large-scale mechanized cotton picking has become a major trend in the cotton industry, leading to the emergence of cotton pickers. Using cotton pickers can effectively increase cotton picking speed and generate higher incomes for pickers. However, the picking performance, clean pick rate, and cotton stripping efficiency of existing mechanized cotton picker heads in my country are far from ideal. This is primarily due to poor design of the cotton picker head, which is the core component that affects the picking performance, clean pick rate, and cotton stripping efficiency.

[0003] Due to the wide range of cotton cultivation, different regions are affected by topography, climate, customs, etc., and the cotton planting methods are also different. For example, the row spacing of cotton ridges is 900 in Qinghai, while in Shandong, the row spacing is 600. There are even narrower areas with row spacing of only 450. Traditional cotton pickers cannot cope with the harvesting of cotton fields with such narrow row spacing. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a traction-type two-row cotton picker with low production cost and strong applicability.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a traction-type two-row cotton picker, comprising a traction head, a frame, a cotton picking head and a cotton collecting bin, the frame being mounted on the traction head and being able to move with the traction head, the cotton picking head and the cotton collecting bin being mounted on the frame, a picking head fixing frame being provided on one end of the frame, two cotton picking heads being mounted on the picking head fixing frame, the sides of the ridge collectors of the two cotton picking heads being located being mirror-imaged along the center line of the traction head, the cotton picking heads being connected to the cotton collecting bin through a cotton conveying pipe, and a cotton blowing fan being connected to the cotton conveying pipe.

[0006] In the above technical solution, the cotton picking head further comprises a shell, a doffing disc assembly is provided in the shell, and a ridge collector is provided at the cotton inlet of the shell.

[0007] In the above technical solution, the ridge collector is arranged at one side of the front end of the shell, and the ridge collectors of the two cotton picking heads are arranged in a mirror image.

[0008] In the above technical solution, the traction head is arranged right in front of the mining head fixing frame.

[0009] In the above technical solution, the picking head fixing frame is provided with a track and a fixing hole, and the cotton picking head is provided with a guide bolt and a fixing bolt. The guide bolt is embedded in the track and can move along the track, and the fixing bolt is installed in the fixing hole.

[0010] In the above technical solution, the middle portion of the guide bolt is fixedly connected to the upper portion of the cotton picking head, and a guide wheel is provided on the end portion, and the guide wheel is embedded in the track of the picking head fixing frame.

[0011] In the above technical solution, the mining head fixing frame is provided with a plurality of fixing holes arranged in a row, and the fixing bolt is inserted into one of the fixing holes.

[0012] To sum up, the technical solution of the present invention has the following beneficial effects compared with traditional technical means: the two cotton picking heads in the two-row cotton picker of the present invention are arranged in a positive and negative manner, and the spacing between the two ridge collectors can be further reduced. In actual use, it is suitable for various row spacings of more than 40 cm, and the applicability is greatly improved. Moreover, the traction head is arranged in the middle front of the two cotton picking heads. This positive pulling traction structure can not only facilitate the alignment of the rows, but also make the vehicle run more smoothly. BRIEF DESCRIPTION OF THE DRAWINGS
