Singularity-free hydraulic bidirectional reversible plow with two oil cylinders

Abstract

The invention relates to a singularity-free hydraulic bidirectional reversible plow with two oil cylinders. The singularity-free hydraulic bidirectional reversible plow with the two oil cylinders comprises a suspension frame, the two hydraulic oil cylinders, a rotary plow frame, a depth limiting wheel and two plow bodies which are arrayed at an angle of 180 degrees, wherein the rotary plow frame is mounted on the suspension frame; the hydraulic oil cylinders are arranged between the rotary plow frame and the suspension frame; the suspension frame comprises a lower suspension beam and an upper suspension beam; a rotating shaft is arranged at the position of a middle point of the lower suspension beam; two hydraulic oil cylinder mounting seats which are not on the same horizontal plane are symmetrically arranged on the upper suspension frame; the rotary plow frame comprises a rotary shaft sleeve and a rotating shaft; two sides of the rotary shaft sleeve are horizontally welded to an overturning beam and a balancing beam; a coordinated driving assembly is mounted in a mounting hole of the overturning beam; the rotary plow frame and the coordinated driving assembly have the same angular displacement movement rule; the coordinated driving assembly comprises a central shaft and two driving arms; the two driving arms are arrayed at an angle of 180 degrees; and the two hydraulic oil cylinders are separately connected with the hydraulic oil cylinder mounting seats and the two driving arms of the coordinated driving assembly. The problem that singularity exists in an overturning process of the traditional reversible plow is solved fundamentally.

Description

Technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, and specifically relates to a non-singular two-cylinder hydraulic bidirectional turning plow for mechanical farming. Background technique [0002] The two-way flip plow is a kind of agricultural machinery and equipment for plowing and turning the land. It can turn the low-fertility upper layer of soil to the lower layer, and turn the lower layer of better soil to the upper layer to remove stubble, weeds, fertilizers, and pests. When buried in the soil, the soil can also be loosened, so that proper air and moisture can be retained in the soil to facilitate the growth of crops. The two sets of plow bodies installed on the plough frame can be turned and work alternately to reduce tractor empty Itinerary improves the efficiency of tillage. [0003] With the rapid development of agricultural machinery, the two-way flip plow has been more widely used. The traditional two-way fli...

In addition, although the mechanism can cross the singular position under the action of inertia, near the singular position, the inverse dynamic equation of the mechanism has multiple solutions, which leads to the loss of control of the mechanism, poor operability and stiffness
