Cotton topping device and method for inhibiting cotton leaves from being damaged

Abstract

The invention relates to a cotton topping device for inhibiting cotton leaves from being damaged. The cotton topping device comprises a frame, a plant height sensing mechanism arranged in the frame and a topping mechanism arranged at the front end of the frame. The cotton topping device for inhibiting the cotton leaves from being damaged is high in precision of identifying the position of a cottontip. Through an imager and a controller, instantaneous synchronism of non-contact identification and mechanical profiling is met, and the precision is improved; damage to plants is reduced through acutting-free beating method; the growth characteristic that the tip of a cotton plant body is crisp and tender can be fully utilized, and the cotton leaves with photosynthesis are preserved to the maximum extent; during multi-row topping, all topping single bodies can independently run and do not interfere with one another; and the beating amplitude and force can be adjusted according to the growth states of different varieties, and different topping requirements are met.

Description

technical field [0001] The invention relates to a cotton topping device and a topping method for suppressing damage to cotton leaves, and belongs to the technical field of agricultural machinery. Background technique [0002] Cotton crops have the characteristics of "top growth advantage", and cotton topping is an indispensable and important link in its production process. By removing the top core of cotton, it can not only promote boll formation of cotton plants, increase production and income, but also improve cotton quality. In the past, most of the traditional manual topping was used, the production efficiency was low, and the single topping method has become less and less suitable for the development needs of the cotton industry; in recent years, some areas have tried chemical topping methods, but the topping effect is affected by climate conditions The difference in the impact of these factors is obvious, or it may cause serious cotton production reduction, environmen...

Problems solved by technology

Chinese patent application number 200720126953.8 discloses a cotton topping machine with automatic height adjustment, which can automatically adjust the topping height to the ground surface and the height of the cotton plant, but it cannot realize the random profiling of the top of a single plant. High missed or over-hit rate

Chinese Patent Application No. 200920164577.0 discloses an automatic adjustable cotton topping machine, which adopts an electric contact profiling adjustment mechanism, which has a narrow application range and a high topping failure rate

Chinese patent application number 201110319598.7 discloses a self-control profiling cotton topping machine, which can complete topping under the condition of high consistency of cotton height, but it is not suitable for most situations with large difference in cotton height

Chinese Patent Application No. 201210382667.3 discloses a vertical lifting single-body profiling cotton topping machine, which uses a profiling plate to profil the top of the cotton plant, and relies on pressure sensing to push down the cotton plant, resulting in missed beating Serious, and the topping height is controlled by high and low positions, the control accuracy is poor, and it cannot adapt to the cotton with large height changes

Chinese patent 201811228003.5 discloses a slip-through cotton topping machine, which reduces the overcutting of some cotton leaves due to topping, but the mechanism lacks profiling and positioning of the cotton top core, and it is easy to top the cotton plant and not cut it. to top core

The traditional flat cutting method seriously damages the cotton leaves, and the rolling cutting method is also easy to push down the cotton, and the topping effect is poor
