Description

GPS intelligent rotary tillage and leveling all-in-one machine

technical field

The utility model relates to the field of agricultural machinery, in particular to a GPS intelligent rotary tillage and leveling integrated machine.

Background technique

The agricultural grader consists of a frame, a traction (or suspension) device, a leveling shovel and its manipulation, adjustment device, and loosening shovel. It has the anti-profiling performance that makes the leveling shovel move up and down without following the undulation of the ground, so as to obtain the effect of leveling the farmland. There are three types of agricultural graders: (1) The traction grader has a large longitudinal span, a large distance between the bulldozer blade and the rear wheel of the tractor, good anti-profiling performance, good leveling quality, and reliable work, but the structure is more complicated. Large consumption, suitable for large area leveling operations. There are two types of walking devices: four-wheel and two-wheel. The two-wheeled front end is supported by a tractor. (2) The suspended grader has simple structure, light weight, less steel consumption, and flexible maneuverability, but the longitudinal span is small, the distance between the grader and the rear wheel of the tractor is small, the anti-profiling performance is poor, and the grade quality is poor. It is suitable for Work on small plots. (3) The front end of the frame of the semi-suspended motor grader is hooked to the suspension mechanism of the tractor, and the rear end has supporting wheels. Compared with the traction type, the structure is simpler, the weight is lighter, the operation is convenient, and the quality of the flat ground is better than that of the suspension type.

However, the above-mentioned graders all have a common defect. For small pits in the land, the use of agricultural graders can achieve the effect of leveling the land. When on a slope, the grader’s own leveling frame is not horizontal, so when a slope appears, it will also level the ground with the slope. Finally, a slope will appear in the field, which is not conducive to the diversion of rainwater, and there will be water accumulation. affect the growth of crops.

The laser graders developed in recent years have better leveling benefits, but the cost of leveling is high, and the laser is greatly affected by the weather. Especially for paddy fields with small slopes, it is not worth the candle and has a single function.

In recent years, there has been an attempt of an inertial leveling system, but this system only solves the problem of the left and right levels, and cannot solve the problem of the front and rear levels during the travel of the implement.

Utility model content

Based on the problem that the existing graders have either single function or high cost, a GPS intelligent rotary tillage and leveling all-in-one machine that can automatically adjust up and down, left and right, and can be folded is proposed.

The technical scheme that the utility model adopts is as follows:

The GPS intelligent rotary tillage and leveling all-in-one machine includes an adjustable suspension frame. The lower end of the adjustable suspension frame is provided with a folding suspension frame. The folding suspension frame is connected by the rotation shaft of the suspension frame; the middle gear box is arranged in the folding suspension frame; the middle gear box is connected with the side gear box;

An adjustment oil cylinder is arranged between the upper support point of the adjustment oil cylinder of the adjustment suspension frame and the lower support point of the adjustment oil cylinder, and a folding oil cylinder is arranged between the folding suspension frame and the hood, and the hood and the folding suspension frame are hinged through the folding rotation point. The adjustment oil cylinder is connected with the hydraulic valve.

Further, the output shaft of the intermediate gear box is connected with the side gear box through the transmission shaft.

Further, the hydraulic valve is placed on the adjustment suspension frame.

Further, the hood is divided into left and right hoods.

Further, hydraulic locks are provided on the adjusting cylinder and the folding cylinder.

Further, the number of the adjusting cylinders and the folding cylinders are 2-4 respectively.

The utility model has the following beneficial effects:

In view of the unevenness of the land and the appearance of the slope, the oil cylinder can be controlled and adjusted by the hydraulic valve to ensure that the field is leveled after the grader works.

With the folding oil cylinder, the hood assembly on the left and right sides can be put away, which is convenient for transportation, and it will not be unable to be transported due to its large size.

When the traction device moves up and down on the uneven ground, the grader will not be disturbed, and the leveling height will be automatically adjusted for operation.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 1 and 2, the GPS intelligent rotary tillage and leveling all-in-one machine includes an adjustable suspension frame 2. There is a knife shaft 14; it is characterized in that: the adjustable suspension frame 2 and the folding suspension frame 3 are connected through the suspension frame rotating shaft 4; the folding suspension frame 3 is provided with an intermediate gear box 1; the intermediate gear box 1 and the side gear box 8 connection;

An adjustment oil cylinder 5 is arranged between the upper support point 12 of the adjustment oil cylinder of the adjustment suspension frame 2 and the lower support point 13 of the adjustment oil cylinder. The frame 3 is hinged through the folding rotation point 11, and the adjusting oil cylinder 5 is connected with the hydraulic valve 7.

The output shaft of the intermediate gear box 1 is connected with the side gear box 8 through the transmission shaft 9 .

The hydraulic valve 7 is placed on the suspension frame 2 for adjustment.

The hood 10 is divided into left and right hoods.

The adjusting oil cylinder 5 and the folding oil cylinder 6 are provided with hydraulic locks.

The quantity of the adjusting oil cylinder 5 and the folding oil cylinder 6 is 2-4 respectively.

Example:

The GPS intelligent rotary tillage and leveling all-in-one machine receives GPS satellite signals through the satellite antenna on the hood, and the controller converts the satellite signals into the action signals of the hydraulic valve, and controls and adjusts the action of the oil cylinder 5 through the hydraulic valve to make the implement work at a predetermined elevation. When the ground is high on the left and short on the right, and the traction device is also high on the left and short on the right, the flow rate of the hydraulic valve 7 will automatically change, so that the adjustment oil cylinder on the left is extended and floated, and the adjustment cylinder on the right is shortened and floated, so as to realize left and right Level, when adjusting, adjust the upper and lower long slots on the suspension frame to move up and down along the rotating shaft 4 to achieve front and rear levels, so as to realize that the equipment is still operating at a predetermined elevation, so as to realize the integration of farming and flat land.

After the operation, the machine cover 10 can be folded up at 90 degrees by folding the oil cylinder 6, which is convenient for transportation.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the utility model , should be covered within the scope of protection of the utility model.
