Cotton topping machine

Abstract

The invention belongs to the cotton plant machinery, particularly relating to a cotton topping machine, which comprises a machine rack with lifting lugs; profiling land wheels with support arms are respectively hinged at both sides of the machine rack; a hydraulic oil cylinder is hinged on each support arm; the end part of a piston of the oil cylinder is hinged on the upper part of the machine rack; the front end of a floating machine rack hinged at the lower part of the machine rack is provided with movable cutter heads through bearing seats; each movable cutter head is provided with evenly distributed wire-cutting movable cutters; a main transmission shaft drives the corresponding movable cutter head respectively through the evenly distributed belt wheels; wire-cutting fixed cutters matched with the wire-cutting movable cutters of the movable cutter heads are arranged on the floating machine rack; symmetric straw lifters are arranged at both sides of the movable cutter heads througha four-rod mechanism connected with the machine rack and the floating machine rack; one end part of a supporting rod is fixedly connected with a profiling boot, while the other end of the supporting rod is fixedly connected on the floating machine rack; and a spring mechanism is arranged between the machine rack on the upper part of the profiling boot and the floating machine rack. The cotton topping machine replaces artificial topping by mechanical operation to improve productivity and reduce production costs, and has the advantages of light cutting tools, long service life, strong adaptability to cotton height, as well as good cotton topping results.

Description

technical field [0001] The invention belongs to cotton planting machinery, in particular to a cotton topping machine. Background technique [0002] The development of cotton topping machinery in my country is relatively slow. At present, cotton topping is mainly done manually, which not only has high labor intensity, low productivity, but also high production cost. In Xinjiang, early July is the best topping period for cotton, and the time is about 10 days, while manual topping is only 3-5 mu a day, which is labor-intensive and slow. It takes about ten days to complete, resulting in uneven growth of cotton and differences in boll opening time. [0003] At present, the existing cotton topping machine in China is the horizontal knife throwing type. The horizontal blade type has poor profiling, the operating height of the blade within the working width is the same, the adaptability to the height of cotton is poor, the topping is not thorough, and multiple operations are requi...

AI Technical Summary

Problems solved by technology

The horizontal blade type has poor profiling, the operating height of the blade within the working width is the same, the adaptability to the height of cotton is poor, the topping is not thorough, and multiple operations are required for complete topping; foreign countries have realized cotton self-capping in breeding research, or rely on Drugs control top growth, which is difficult to apply in my country's production practice
