Embodiment Construction

[0007] like figure 1 Shown, the present invention comprises front end tractor, rear end tractor and constitutes. The front-end tractor is connected with the rear-end tractor with the hinge pin 4 and the spacer bushing 5 . The front end tractor is composed of a traction plate 8 , a traction longitudinal plate 6 , and a limiting plate 7 . Wherein the traction plate is inserted into the gap on the side of a pair of traction longitudinal plates 6 , a pair of traction longitudinal plates 6 are respectively fixed on the two sides of the traction plate 8 , and the limiting plate 7 is fixed below the pair of traction longitudinal plates 6 . The rear tractor is composed of a traction screw 1 and a U-shaped traction rod 2 . Among them, the traction screw 1 passes through the U-shaped traction rod 2, and the threaded section of the traction screw 1 fixes two hexagonal nuts 3, the U-shaped traction rod 2 is blocked by the hexagonal nuts 3 and cannot be separated from the traction screw ...

Abstract

The invention relates to a three-degree-of-freedom tractor for an agricultural laser grader. It consists of a front tractor and a rear tractor. The front-end tractor is connected with the rear-end tractor with a hinge pin and a spacer sleeve. The front tractor is composed of a traction plate, a traction longitudinal plate and a limiting plate. The front part of the traction plate of the front-end tractor is inserted into the tractor traction frame, and the pin shaft passes through the traction frame and the traction plate, so that the front-end tractor is connected with the tractor. The small shaft diameter section of the rear tractor is inserted into the front plate of the traction frame of the motor grader and fixed by welding. When the tractor pulls the grader to turn, the front traction plate rotates around the tractor pin shaft; when the tractor pitches longitudinally or the grader adjusts the blade height, under the action of the ground wheel control device of the grader, the rear tractor revolves around the front tractor The connected pin shaft rotates; when the tractor swings laterally or the grader adjusts the cutting edge parallel to the laser reference plane, under the action of the left and right ground wheel control devices of the grader, the grader rotates around the front and rear tractors through the traction screw .

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a three-degree-of-freedom tractor for an agricultural laser grader. Background technique [0002] In daily life, when farmers use the grader, it is a time-consuming and labor-intensive task for the rotation of the grader, the waste of water and the loss of fertilizer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a three-degree-of-freedom tractor for agricultural laser graders, so as to achieve the effect of simple structure, good reliability, low cost, and accurate and efficient land leveling by agricultural laser graders. [0004] In order to solve the above problems, the present invention provides a three-degree-of-freedom tractor for graders, which is composed of a front tractor and a rear tractor. The front-end tractor is connected with the rear-end tractor with a hinge pin and a spacer sleeve. ...
