Veridical lifting type monomer copying cotton topping machine

Abstract

The invention relates to a veridical lifting type monomer copying cotton topping machine based on electric hydraulic control, comprising a combined rack, a drive system, an electrical system, copying platforms and a topping device. The copying platforms are arranged at the lower part of the combined rack, the number of the copying platforms are accordant with the work line number of the topping device, the copying platforms are respectively connected with a lifting oil cylinder fixed on the rack and a topping device cutter shaft arranged in a sleeve drive system by a pin and a bearing base, and the electric system is fixed at the front end and the upper part of the combined rack. The veridical lifting type monomer copying cotton topping machine is characterized in that the topping device cutter shaft not only can rotate but also can be vertically lifted up and down in a sleeve along with the copying platforms; the front-and-back position of a copying device on the copying platforms can be adaptive to various work speeds of the topping machine; and the assembled rack of the topping machine can meet the requirement of the different work widths or line numbers according to the number of the copying platforms.

Description

Technical field: [0001] The invention relates to a field operation machine for crops, in particular to a vertically lifting single-body profiling cotton topping machine for the field operation machine for crops. Background technique: [0002] At present, the topping operation of cotton seedlings mostly adopts drug control and manual topping. The former pollutes the environment and the latter is labor-intensive and low-efficiency, both of which restrict the development of mechanization of cotton production.

AI Technical Summary

Problems solved by technology

[0002] At present, the topping operation of cotton seedlings mostly adopts drug control and manual topping. The former pollutes the environment and the latter is labor-intensive and low-efficiency, both of which restrict the development of mechanization in the whole process of cotton production.

[0003] Chinese patent announcement number: the patent of CN201078930, the disclosed cotton topping machine with automatic height adjustment, its structure includes fixed frame, floating frame, a lifting mechanism, a grain lifter, a rotating The topping knife and the hydraulic transmission mechanism are provided with a suspension frame on the fixed frame, and a lifting oil cylinder is set between the fixed frame and the floating frame, and a hydraulic motor, a grain lifter, and a rotating topping knife are arranged under the floating frame. And its automatic lifting system composed of ultrasonic sensor, signal processor and CPU has complex structure and high failure rate

Chinese patent announcement number: the patent of CN201528557U, the structure is made of suspension frame, frame, transmission mechanism, rotary topping knife and the automatic adjustment device on the frame, and described automatic adjustment device is made of sensor, electromagnetic valve and lifting oil cylinder, The sensor is arranged on the floating bar at the bottom of the frame, the sliding shovel plate under the floating bar, and the conductive stagnation piece and power supply connected with the floating bar. The stagnation piece is connected with the solenoid valve of the power supply box to form a voltage loop. Lifting cylinder connection, its structure is characterized by complex structure and high topping failure rate

The feature disclosed in the profiling cotton topping machine of Chinese Patent Application No. 20091011325.X is to measure and profile cotton of different heights according to terrain conditions, but it cannot realize the random profiling of the top of a single cotton plant
