Description

Technical Field

[0001] The invention relates to a land shaping device, in particular to an operating device of a suspended multifunctional land leveler. Background Art

[0002] The motor grader is the main machine used for shaping and leveling in earthmoving operations. It uses a blade to cut, scrape and level the soil. It is a construction machine with high efficiency, good operating precision and wide application.

[0003] At present, most dry land graders are traction type, with the blade at a small angle to the ground surface and baffles on both sides of the blade. During operation, the space between the baffle and the blade has a large amount of soil, high energy consumption, and requires a high-power tractor. In addition, the turning radius of the traction grader is large, and it is impossible to turn around in a small range. There are turns during operation, and high control skills are required for the driver to achieve high efficiency, no duplication, and no missed leveling. In addition, due to the turning radius, the corner of the field is a blind spot for operation.

[0004] The paddy field preparation process generally includes rotary tillage (or plowing), paddy field beating and leveling. Usually, the paddy field needs to settle for a period of time after beating before leveling, and the operation cycle is long. The existing paddy field levelers with integrated beating and leveling functions still have different degrees of shortcomings such as weeds, reliability, and high energy consumption.

[0005] It is understood that some cooperatives, farms, and agricultural reclamation need to be equipped with both paddy field graders and dry field graders to meet the needs of different fields, and the maintenance and management of the machines is relatively troublesome. At present, there is no grader that can be used for both paddy and dry fields. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide an operating device of a suspended multifunctional grader in view of the defects of the prior art.

[0007] In order to achieve the above object, the present invention provides an operating device of a suspended multifunctional grader, which includes:

[0011] A main blade, mounted on the rotating frame;

[0012] A rotary cylinder, one end of which is hinged to the vehicle frame, and the other end of which is hinged to the rotating frame, wherein the rotary cylinder drives the main blade to rotate in a horizontal direction relative to the vehicle frame through the rotating frame; and

[0013] The flip cylinder is used to drive the main blade to flip longitudinally to realize the conversion of the leveling mode, the grass pressing mode and the bulldozing mode. The flip cylinder is connected to the main blade and drives the main blade to switch between the leveling position, the grass pressing position and the bulldozing position respectively.

[0014] In the operating device of the above-mentioned suspended multifunctional grader, the cross section of the main blade is an arc-shaped plate, a main shovel edge is installed at the lower end of the main blade, and the outer surface of the arc-shaped plate of the main blade is evenly distributed with grass pressing teeth.

[0015] The working device of the above-mentioned suspended multi-functional grader, among others, also includes an auxiliary blade, which is connected to one side or both sides of the main blade, and an auxiliary blade is installed at the lower end of the auxiliary blade, and the cross-section of the auxiliary blade is an arc-shaped plate with the same cross-section as that of the main blade, and the outer surface of the arc-shaped plate of the auxiliary blade is evenly distributed with grass pressing teeth.

[0016] In the operating device of the above-mentioned suspended multifunctional grader, a connection reinforcement plate is provided at the connection between the main blade and the auxiliary blade.

[0017] The working device of the above-mentioned suspended multi-functional grader, wherein the flip cylinder is connected to the main blade through a pull rod and a blade driving arm, a pull rod fixing seat is provided in the middle of the main blade, one end of the pull rod is hinged to the pull rod fixing seat, the other end of the pull rod is connected to the blade driving arm, and the blade driving arm is connected to the flip cylinder.

[0018] In the operating device of the above-mentioned suspended multifunctional grader, at least one rotating frame fixing seat is further provided on the main blade, and the rotating frame is hinged to the rotating frame fixing seat.

[0019] In the above-mentioned working device of the suspended multifunctional grader, there are two rotating frame fixing seats, which are symmetrically arranged on both sides of the pull rod fixing seat and close to the two ends of the main blade.

[0020] In the operating device of the above-mentioned suspended multifunctional grader, the main blade and the auxiliary blade are longitudinally flipped 180° with the hinge axis of the rotating frame fixing seat as the center.

[0021] In the working device of the above-mentioned suspended multifunctional grader, the rotary cylinder drives the main blade to rotate ±15° in the horizontal direction relative to the frame through the rotating frame, and guides the loose soil gathered on the main blade to move to one side by adjusting the angle of the main blade in the horizontal plane, so as to avoid and reduce the overflow of the loose soil into the working area, and facilitate the processing of corners and the filling of gullies and depressions.

Compared with the existing traction-type graders, the suspended arc-shaped plate blade makes the operation flexible, convenient for handling the corners of the field, and has no blind spots. By adjusting the horizontal angle of the blade, the loose soil gathered on the blade can be guided to move to one side of the blade, avoiding and reducing the overflow of loose soil to the operating area, and it is also convenient for handling corners and filling gullies and depressions; it can also be used for rough leveling of paddy fields with large drop, as well as other practical operation needs. The grass pressing mode is mainly used for paddy field operations. There is no need for beating, and the paddy field is directly leveled. At the same time, the weeds and straws in the mud are deeply pressed, and there is no need for manual salvage later, saving a lot of manpower, material and physical strength. The bulldozing mode can be used to solve some situations where simple bulldozing is required in some fields, such as filling edges, filling pits, and moving soil. When working in paddy fields, the auxiliary blade can be equipped according to the actual situation to increase the width and further improve the operation efficiency. The operating device can be used in conjunction with a grader control system to give full play to its structural characteristics and achieve automatic leveling to meet the high requirements of dry fields, especially paddy fields, on field levelness.

The flip cylinder 9 is connected to the main blade 4 through the pull rod 5. The other end of the flip cylinder 9 is hinged with the rotating frame 2 and connected to the tractor through the oil pipe. The flip cylinder 9 can drive the main blade 4 to switch between the leveling position, grass pressing position and bulldozing position respectively through the blade driving arm 8 and the pull rod 5. The leveling mode is used for dry land leveling operations and rough leveling of paddy fields with large drop; the grass pressing mode is used for paddy field leveling operations and deep pressing of weeds and straws in paddy field mud; the bulldozing mode is used for simple bulldozing operations in the field.

[0056] In this embodiment, the cross section of the main blade 4 is preferably an arc-shaped plate, a main blade 41 is fixedly mounted at the lower end of the main blade 4, and main grass-pressing teeth 42 are evenly fixed on the outer surface of the arc-shaped plate of the main blade 4. A secondary blade 6 may also be included to make the blade length adjustable, the secondary blade 6 is connected to one or both sides of the main blade 4, a secondary blade 61 is mounted at the lower end of the secondary blade 6, the cross section of the secondary blade 6 is an arc-shaped plate with the same cross section as the main blade 4, and secondary grass-pressing teeth 62 are evenly distributed on the outer surface of the arc-shaped plate of the secondary blade 6.

When the working device of the present invention moves forward with the tractor, as shown in FIG. Figure 6B As shown, since the force direction of the main blade 4 on the soil is perpendicular to the main blade 4, the loose soil accumulated on the main blade 4 can be guided to move to the right side of the blade. Similarly, when in Figure 6C In the blade state shown, the loose soil accumulated on the main blade 4 can be guided to move to the left side of the blade, avoiding and reducing the overflow of the loose soil into the working area, and also facilitating the processing of corners and filling of gullies and depressions.

[0059] The present invention can realize three main working modes of leveling, weed pressing and bulldozing, and can be used to level paddy fields and dry fields. The leveling mode is mainly used for dry field operations. Compared with the existing traction-type land leveler, the suspended arc-shaped plate blade makes the operation flexible, convenient for handling the corners of the field, and has no blind spots. By adjusting the horizontal angle of the blade, the loose soil gathered on the blade can be guided to move to one side of the blade, avoiding and reducing the overflow of loose soil to the operating area, and also facilitating the handling of corners and filling gullies and depressions; it can also be used for the rough leveling of paddy fields with relatively large drop, as well as other practical operation needs. The weed pressing mode is mainly used for paddy field operations. There is no need for pulping, and the paddy field can be directly leveled. At the same time, the weed straw in the mud can be deeply pressed through the weed pressing teeth on the back of the blade, without the need for manual salvage in the later stage, saving a lot of manpower, material and physical strength. The bulldozing mode can be used to solve some situations where simple bulldozing is required in some fields, such as filling edges, filling pits, moving soil, etc. When working in paddy fields, the auxiliary blade 6 can be installed according to the actual situation to increase the width and further improve the working efficiency. The working device can be used in conjunction with the grader control system to give full play to its structural characteristics and realize automatic leveling to meet the high requirements of dry fields, especially paddy fields, for the levelness of the field. Through simple operation, it can quickly switch between the leveling mode, grass pressing mode and bulldozing mode, realizing the dual-use of one machine for both water and land, saving procurement, maintenance and management costs; it has multiple functions and no dead angles in operation.

[0060] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
