Description
Technical Field
The utility model relates to a pneumatic auxiliary plate tooth type cotton picking table, and belongs to the technical field of cotton mechanized harvesting.
Background
Currently, cotton mechanized harvesting technologies representing the world's advanced level are johndil (DEER) and kesi (CASE) in the united states, and their models are largely classified into harvest-type models and harvest-type models. On the basis of advanced technology of digestion and absorption abroad, the horizontal spindle cotton picker is demonstrated and popularized in partial areas in China, and has the advantages of high production efficiency, low impurity content and the like; however, the production and use costs are too high, and the method is not suitable for cotton varieties with high plants, low density and high yield and planting agronomy in some areas, and is difficult to popularize in a large area in the whole country. The system-collecting type represented by a brush roller type cotton picker, a finger brush type cotton picker and the like has the advantages of wide application range, low production, use and maintenance cost, high clean rate and higher cost performance; however, cotton boll, boll shell and seed cotton can be picked together in the cotton picking process, and pretreatment links such as airborne clear boll, clear boll shell and clear broken leaves are added subsequently, so that cotton fibers can be damaged to a certain extent.
To the best of applicant's knowledge, there are also many hand-held cotton pickers currently available to assist in picking cotton manually. For example, chinese patent application No. 200920128517.3 discloses a hand-held cotton picker. The main collecting wheel and the needles on the 2 auxiliary collecting wheels of the machine scrape cotton into the picking bin from the front and two sides respectively through the rotation motion of the needles, and the picked cotton is transmitted to the collecting place along with the cotton conveying belt. However, gaps exist between the cotton stripping plates and the belts, so that cotton is blocked in the shell, and the work is affected.
For this reason, the chinese patent application No. 201310304953.2 discloses a cotton picking needle, a cotton picking device and a cotton picking machine. The cotton picking needle of the machine moves in parallel along with the conveying belt, and the vertical line segment is changed into the inclined segment type, so that the falling phenomenon of picked cotton from the belt is reduced. However, cotton is easy to be entrained by the cotton picking needle, so that the cotton picking channels are piled up to influence picking.
In addition, the Chinese patent application No. 201310400359.3 discloses a hand-held cotton picker. The cotton picking needle of the machine rotates and translates along with the roller, so that the phenomenon of cotton picking needle returning to belt cotton is reduced. However, due to the clearance between the side wall and the roller, the conveying channel is easy to be blocked, and the work is affected.
In summary, the applicant found in working practice that, to achieve mechanical harvesting of the selected cotton, the picking problem is first, and the cotton removal and timely conveying problem is still another; at the same time, the cotton picking stations must have good passability.
