Monocular recognition cotton top-cutting machine

Abstract

The invention relates to a monocular recognition cotton top-cutting machine. The monocular recognition cotton top-cutting machine comprises a grain lifting device, a top-cutting and elevating device, a pulling and supporting device, an image acquiring and processing device, a power unit and a rack. The monocular recognition cotton top-cutting machine is characterized in that the grain lifting device is arranged on the lower end of the rack and is connected with rack, the image acquiring and processing device is arranged on the inner end of a grain lifting baffle plate, the top-cutting and elevating device is arranged on the lower end of a rack plate, and can carry out top-cutting tracking on cotton plant tops, and the pulling device is arranged on the front part of the rack and is connected with a pulling device of a tractor. In the top-cutting and elevating device, a steel wire pulley block and a spring are combined to form the elevating device, a fixed cutter with sawteeth and a fixed pulley form a top-cutting cutter, the fixed cutter is assisted by the grain lifting device in order to form supported cutting, the monocular recognition cotton top-cutting machine is low in energy consumption and stable in cutting, the image acquiring and processing device is composed of a camera and a halogen lamp, a monocular camera is employed to carry out image acquisition, after image processing, the cotton plant height information can be obtained, and furthermore the cutter height is adjusted for carrying out cotton top-cutting work.

Description

technical field [0001] The invention relates to a mechanical device for topping cotton, in particular to a cotton topping machine based on a monocular recognition system, which belongs to the field of agricultural machinery. Background technique [0002] Cotton topping is the process of removing the top growth advantage of cotton by removing the tops of the cotton. Since the winter time in Xinjiang is earlier and the growth cycle of cotton is shorter, it is necessary to suppress the growth of main stem branches and leaves by removing the top advantage, so cotton topping is the central link of cotton pruning work. Through topping, the reproductive organs can be fully grown, and the water and nutrient consumption of ineffective main stems, branches and leaves can be reduced, so that the cotton plants can produce early bolls and more bolls, so that the growth trend of cotton plants can show a tower shape, which is convenient for full photosynthesis , increase the yield of cott...

Problems solved by technology

[0003] Cotton topping machines appeared earlier in foreign countries, but due to the rapid development of foreign biotechnology, drug topping has gradually replaced mechanical topping. However, the land in Xinjiang is relatively barren, and drug topping has caused great damage to the land. Suitable, so mechanical topping is the main trend in the development of cotton topping

[0004] my country's research on cotton topping machines started later than abroad. At present, the topping mechanisms of topping machines mainly include drum type and swing knife type, both of which are unsupported cutting and consume a lot of energy. The existing cotton topping machines The profiling methods are mainly: mechanical contact type, infrared induction type and ultrasonic induction type. The mechanical contact type has more interference, the accuracy is not high, and the field light is complex. The infrared induction type requires a high-demand light interference environment, so it is difficult to achieve Its function, ultrasonic induction, reliability, and accuracy are high, but there is no direction induction
