Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a single-cylinder mechanism for adjusting an offset angle of a reversible plow. Background Art

[0002] When the fixed-width reversible plow and the amplitude-modulating reversible plow are in operation, they need to form a biased angle with the tractor; because the fixed-width reversible plow and the amplitude-modulating reversible plow are operating on leveled ground at the beginning, the wheels on both sides of the tractor are moving on the uncultivated ground on the ground, and the plow main frame and the tractor are moving forward parallel to each other; when they turn back to operate again, the positions of the wheels on both sides of the tractor change, and one side of the tractor's wheels moves under the plowed ground (plow furrow); the other side moves on the unplowed ground; the height difference between the two positions is about 300 mm, so that the tractor forms an offset angle with the ground when operating, so the offset angle between the tractor and the plow main frame needs to be adjusted to make the ground in a relatively flat state after the operation.

[0003] Currently, fixed-amplitude and modulating-amplitude reversible plows are primarily adjusted using manual bolt adjustment and hydraulic cylinder adjustment. Manual bolt adjustment is cumbersome and requires manual adjustment after stopping the plow, which is time-consuming and labor-intensive. Another adjustment method involves using a dual-cylinder system or removing one cylinder from the dual-cylinder system and adding a linkage mechanism. These adjustment mechanisms are not only complex and costly to manufacture, but also have poor adjustment accuracy and are difficult to position. Summary of the Invention

[0004] The purpose of the present invention is to address the defects and shortcomings of the existing technology and provide a single-cylinder mechanism for adjusting the offset angle of a reversible plow with a simple structure, reasonable design and easy use.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: it includes a traction head, a left adjusting arm, a connecting pin, a transverse oil cylinder, a right adjusting arm, a locking nut, an adjusting shaft and an adjusting bolt; the traction head is equipped with a transverse oil cylinder, and the two output ends of the transverse oil cylinder are respectively connected to the left adjusting arm and the right adjusting arm through connecting pins, the left adjusting arm and the right adjusting arm are respectively fixedly connected to the adjusting shafts on the left and right sides, and the adjusting shafts on the left and right sides are respectively equipped with adjusting bolts, and the adjusting bolts are screwed with locking nuts.

[0006] The horizontal oil cylinder is a double-head output oil cylinder, the outer wall of the oil cylinder is the fixed end, the oil cylinder core shaft extends left and right from the outer wall of the oil cylinder and moves in the same direction left and right. The left side of the oil cylinder core is connected to the left adjusting arm, and the right side of the oil cylinder core is connected to the right adjusting arm.

[0007] The left adjusting arm and the right adjusting arm are respectively provided with a long slot which is slidably connected with the connecting pin.

[0008] After adopting the above structure, the beneficial effects produced by the present invention are as follows: the single-cylinder mechanism for adjusting the offset angle of a flip plow described in the present invention significantly improves the reliability of adjusting the flip angle of the flip plow and reduces the complexity of the mechanism. The flip angle can be adjusted instantly without stopping the vehicle. The operator only needs to open the oil valve to extend the cylinder core from one end to the other end to complete the operation. In short, it is a simple and fast operating mechanism, which improves efficiency and reliability, saves manufacturing costs, and is an innovative product that saves cost and increases efficiency. The present invention has the advantages of simple structure, reasonable setting, and low production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The left adjusting arm 2 and the right adjusting arm 5 are respectively provided with an elongated slot which is slidably connected to the connecting pin 3 .

[0016] The transverse oil cylinder 4 is a two-way output oil cylinder, the outer wall of the oil cylinder is a fixed end, and the oil cylinder core can move left and right, that is, the left and right outputs are in the same direction.

[0017] The transverse oil cylinder 4 is a two-way output oil cylinder, the left side of the oil cylinder core is connected to the left adjusting arm 2, and the right side of the oil cylinder core is connected to the right adjusting arm 5.

[0018] The working principle of this specific embodiment is: using a two-way output oil cylinder, as long as the operator opens the oil valve and slides the oil cylinder core from one end to the other end, the flip angle adjustment action can be completed instantly.
