A laser grader

Abstract

The invention discloses a laser land leveling machine and belongs to the technical field of agricultural land leveling machinery. The laser land leveling machine comprises a hitch frame (10) which is mounted on a frame (1), wherein a main working oil cylinder (15) is connected between the frame (1) and the hitch frame (10); an oil filter (12) is arranged on an oil tank (13); the front end of the frame (1) is connected with a main shovel (5), and a scraper blade adjusting mechanism (16) is connected between the hitch frame (10) and the main shovel (5); the rear part of the frame (1) is connected with a traveling mechanism and a balance adjusting mechanism. The laser land leveling machine disclosed by the invention can be used for effectively ensuring the work strength of the frame; the scraper blade can be folded, and is adjustable in working angle, so that the applicability and the universality of the whole machine are increased; the working angle of the frame can be finely adjusted, so that the working range of the whole machine is increased, and the work efficiency is improved; by adopting the four wheel traveling mechanism which is arranged in a staggered manner, the working stability of the whole machine is increased. In a word, the work efficiency of the land leveling machine is integrally improved.

Description

technical field [0001] The invention relates to a laser grader, which belongs to the technical field of agricultural land leveling machinery. Background technique [0002] Laser grader is a high-tech product that applies laser and hydraulic technology to land preparation operations. It is a precision agricultural machine tool and an advanced land preparation machine tool. The laser grader is mainly composed of a laser transmitter, a laser receiver, a control box, a hydraulic control mechanism, and a scraper. [0003] At present, the conventional laser graders on the market are simple in structure and single in form, and it is difficult to adapt to different operating occasions, which has a great impact on the leveling operation. The main defects that exist in the laser grader in the prior art are: [0004] 1. The structure of the traction mechanism is relatively simple, lacks the buffering effect, and it is easy to cause structural damage to the frame during use; [0005]...

AI Technical Summary

Problems solved by technology

[0004] 1. The structure of the traction mechanism is relatively simple, lacks the buffering effect, and it is easy to cause structural damage to the frame during use;

[0005] 2. The working width and working angle of the soil scraper are relatively fixed, which cannot meet different leveling requirements, and the utilization rate is small, and the fixed width may easily lead to poor passability of the whole machine;

[0006] 3. The rear bracket of the grader cannot be adjusted according to different ground conditions, which affects the leveling effect;

[0007] 4. The structure of the support wheel of the grader is single, which leads to poor stability and passability of the whole machine, and it is difficult to meet the leveling requirements of different ground conditions;

[0008] 5. The conventional grader scraper lacks side panels, or the side panel structure is fixed, the scope of application is small, the effect is not ideal, and it is difficult to avoid the phenomenon of soil leakage on the side of the scraper
