Embodiment 1

[0033] An automatic control system for a grader, such as Figure 1-6 As shown, the main body 1 is included. The outer wall of the main body 1 is welded with a control room 2; the control room 2 is provided with a GNSS directional antenna, a GNSS positioning antenna and a ZDT820 positioning and directional terminal device; and the outer wall of the control room 2 passes The lock body is connected with the control room door 3; the inner wall of the main body 1 is fixed with a console by bolts; the outer wall of the console is installed with an operation screen 20 through a mounting seat; and the outer wall of the console is fixed with a USB Interface 18, the user can import the preset design model through the USB interface 18, and transmit the data to the control unit in the control room 2, so that the motor grader can automatically adjust the upper and lower positions of the scraper according to the height of the designed different positions; the main body 1 One side outer wall ...

Embodiment 2

[0042] An automatic control system for a grader, such as figure 1 As shown, in order to further ensure operation safety; this embodiment makes the following improvements on the basis of embodiment 1: the outer wall of the front car body 13 is welded with a connecting frame 12, and the outer wall of the connecting frame 12 is welded with a limit frame 8. A limit slot 29 is provided on the outer wall of the top of the limit frame 8; by setting the limit slot 29, the movable range of the scraper 9 can be further restricted, which ensures the safety of the operation.

[0043] When this embodiment is in use, because one end of the first hydraulic cylinder 15 and the second hydraulic cylinder 19 passes through the limiting groove 29, the scraper 9 is connected via a rotating seat and other mechanisms. If the first hydraulic cylinder 15 and the second hydraulic cylinder 19 are telescopic If the fit exceeds the safe position, or the rotation range of the rotating body 7 is too large, the ...

Embodiment 3

[0045] An automatic control system for a grader, such as figure 1 , image 3 As shown, in order to improve the operating efficiency of the scraper 9; this embodiment makes the following improvements on the basis of embodiment 1: the bottom outer wall of the connecting frame 12 is welded with a spray head 22, a water tank and a pressure pump are arranged inside the control room 2, and the spray head 22 passes The internal water pipe is connected with the water tank, the spray head 22 and the pressure pump are controlled by the control unit, and the outer wall of the spray head 22 is provided with evenly distributed spray holes 23; by setting the spray head 22, the scraper 9 can be cleaned by controlling the spray head 22 to spray water, thereby Improve operational fluency and increase operational efficiency.

[0046] In order to increase the scope and cleaning effect; such as image 3 As shown, the spray head 22 has a horn-shaped structure. By setting the spray head 22 in a horn-sh...

Abstract

The invention relates to an automatic control system of a land leveler. The system comprises a main body, wherein a control chamber is welded to an outer wall of one side of the main body, a directional antenna, a positioning antenna and a positioning and orienting terminal device are arranged in the control chamber, and an outer wall of one side of the control chamber is connected with a controlchamber door through a lock body. The system is advantaged in that by arranging a first positioning antenna sensor, a second positioning antenna sensor and an inclination angle sensor, a scraper can be positioned, so the land leveler can level a to-be-leveled surface with longitudinal and transverse gradients, by arranging a USB interface and an operation screen, the vertical position of the scraper can be automatically adjusted according to an imported model, an application range of the land leveler is expanded, and applicability of the land leveler is enhanced, by setting three-dimensional design model display of the operation screen, according to graphical and three-dimensional information reference, an operator can visually know the flat ground state information, and construction is rapid.

Description

Technical field [0001] The invention relates to the technical field of motor graders, in particular to an automatic control system for motor graders. Background technique [0002] Earthwork is one of the main projects in construction engineering, and the grader is an earth-moving machine that uses a scraper to level the ground. It is the main machine used for reshaping and leveling in earthwork. However, most of the current graders often fail to meet the requirements. . [0003] The existing leveling shovel device includes a leveling shovel arranged on the body of the leveler, the leveling shovel is in contact with the ground, the lower part of the leveling machine body is provided with a leveling shovel mounting plate, and the lower surface of the leveling shovel mounting plate is slidingly connected with a connecting block along the length direction , The bottom surface of the connecting block is vertically downwardly provided with a longitudinal rotating cylinder, and the shove...
