Double-oil-cylinder hydraulic lifter for tractor

Abstract

The invention discloses a double-oil-cylinder hydraulic lifter for a tractor. The lifter comprises a shell, two lifting arm assemblies are symmetrically installed on the shell, a lifting driving device is installed in the shell, and an angle detection device and an angle feedback device are installed on each lifting arm assembly; each lifting arm assembly comprises an inner lifting arm, lifting arm shafts are rotationally installed on the shell, one end of each lifting arm shaft extends into the shell and is fixedly connected with the corresponding inner lifting arm, and the other end of eachlifting arm shaft extends out of the shell and is fixedly provided with an outer lifting arm; and the lifter is provided with double lifting driving devices which can control the two lifting arm assemblies to work respectively, achieves self-adaptive adjustment of agricultural implements on different farming conditions, is more suitable for agricultural farming operation of tractors in uneven areas, improves the operation quality and the operation efficiency of the tractors, reduces the damage rate of the agricultural implements and hydraulic elements, and reduces the amount of loss of fuel.

Description

technical field [0001] The invention relates to the technical field of agricultural tractor accessories, in particular to a double oil cylinder hydraulic lifter for tractors. Background technique [0002] As the main tool of agricultural mechanization, tractor is the most widely used in agricultural production. It is the main power output source of various types of agricultural machinery, and it is also an important symbol of agricultural mechanization. At present, most domestic tractor lifters are composed of lifter housing, inner lift arm, lift shaft, outer lift arm, single-acting independent oil cylinder, piston, distributor, safety valve, descending speed regulating valve, force feedback subassembly, operation institutions etc. The lifter is an important working device of the tractor, and its performance stability directly affects the farming quality and efficiency of the tractor. However, in the process of operation, terrain undulations, short-term sudden changes in t...

Problems solved by technology

However, in the process of operation, terrain undulations, short-term sudden changes in terrain such as field ridges and tree roots, and sudden changes in resistance are often encountered, causing tractor implements to fluctuate up and down, unable to perform self-regulation, and may damage agricultural implements and hydraulic components.
