Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery auxiliary machinery, in particular to a frame-type side-shift three-point suspension frame. Background Art

[0002] In the process of agricultural production, the working width of the operating machinery and the existing power-driven machinery is often inconsistent, and there is a technical problem that the width cannot be adapted. In particular, in the process of agricultural production, generally only one set of tractors is configured for traction operations. The above tractors will not be replaced unless there is a failure or damage. However, due to the different operating requirements of film covering, rotary tillage, suppression, ditching, and ridging, the operating machinery is often equipped with multiple sets of equipment. In actual use, there will be a situation where the traction width is different from that of the operating machinery. In particular, when a large-horsepower and large-width tractor pulls a machine with a smaller working width, the tractor wheelbase is larger than the machine working width, which will cause the adjacent row spacing between the two working widths to be too large. Careless operation and driving will cause part of the working surface to be missed. Repairing the missed working surface will repeatedly crush the land that has been worked, causing unnecessary waste of power and fuel. At the same time, it is also difficult to repair the tractor's running trajectory control. The land that has been repeatedly crushed by the tractor is not covered and missed by the width of the operating machine, resulting in the missed plots of soil being too firm, which is not conducive to crop growth. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a three-point suspension frame which can slide left and right behind the tractor suspension frame, so as to solve the problem that the width of the tractor and the working machine are not matched, improve the land utilization rate, the utilization rate of the working machine, and reduce the compactness of the missed soil.

[0004] In order to solve the technical problems of the utility model, the following technical solutions are adopted:

[0005] The frame-type side-shift three-point suspension frame includes a tractor and an operating machine; it also includes a motor frame and a fixed frame, the motor frame includes a machine attachment plate, a side-shift frame crossbeam and a fixed beam, the machine attachment plate and the fixed beam are spliced ​​to form a fixed frame, and the fixed frame is provided with a side-shift frame crossbeam; the motor frame is arranged between the machine attachment plates, and the fixed frame includes a sliding tube and a tractor attachment plate; a tractor attachment plate is provided on the sliding tube, the sliding tube is sleeved on the side-shift frame crossbeam, the tractor attachment plate is connected to the tractor trailer, and the machine attachment plate is fixedly connected to the operating machine. The fixed frame of the utility model is attached to the tractor, and the motor frame slides along the fixed frame to achieve position adjustment, and the width adjustment of the operating machine is achieved by changing the relative position of the motor frame and the fixed frame. There is no need for the tractor to repeatedly travel to cover the missed land.

[0006] The fixed frame is fixedly connected with a hydraulic side shift device, which includes a hydraulic oil pipe, a hydraulic push rod and a side shift cylinder; the side shift cylinder includes an oil storage chamber and an oil seal plug, and the hydraulic push rod is divided into a hydraulic push rod I and a hydraulic push rod II, and the hydraulic push rod I and the hydraulic push rod II are respectively provided with a clamping section and an oil seal section; the oil seal sections of the hydraulic push rod I and the hydraulic push rod II are sleeved in the side shift cylinder, and the oil seal sections of the hydraulic push rod I and the hydraulic push rod II slide along the oil storage chamber of the side shift cylinder, and the oil storage chamber is connected to the hydraulic oil pipe; the clamping sections of the hydraulic push rod I and the hydraulic push rod II are fixedly mounted on the machine tool mounting plate. The relative position of the machine frame and the fixed frame is adjusted by pushing the side shift cylinder to move by hydraulic oil, so as to achieve precise adjustment of the width of the working machine tool.

[0007] The oil storage chamber is connected to two hydraulic oil pipes, which are respectively located at the two ends of the side shift cylinder. The oil storage chamber is connected to the two hydraulic oil pipes, one of which is located between the oil seal sections of hydraulic push rods I and II, and the other is located between the oil seal section of hydraulic push rod II and the oil seal plug of the side shift cylinder. The two hydraulic oil pipes are connected to the oil storage chamber and combined with the sealing of the oil seal section and the oil seal plug, the oil storage chamber is divided into two chambers, and the hydraulic oil is introduced into the two hydraulic oil pipes respectively. The position adjustment of the side shift cylinder is achieved by introducing the amount of hydraulic oil from different hydraulic oil pipes. The two chambers are filled with oil to achieve pressure balance and position limitation in the oil storage chamber. At the same time, when the machine is impacted and bumped during operation, the oil filling chamber can also provide a buffering effect. The above-mentioned equipment only introduces hydraulic oil to generate pressure changes to drive the displacement of the side shift cylinder when adjusting the position. It has low requirements for oil pressure and sealing, and is particularly suitable for use in farmland operations.

[0008] The invention is characterized in that two sliding tubes are provided, and the two sliding tubes are arranged in parallel. The two sliding tubes are respectively mounted on two moving frame cross beams, so that the tractor can travel more smoothly and stably along the forward direction of the tractor.

[0009] The utility model also includes a rubber buffer sleeve, which is sleeved on the side shift frame cross beam, and the rubber buffer sleeve is sleeved on the end of the sliding tube, and the rubber buffer sleeve moves along the side shift frame cross beam with the sliding tube, so as to improve the dustproof effect and further improve the shock absorption and buffering performance.

[0010] The width of the side shift frame crossbeam is greater than the width of the sliding tube. The fixed frame is provided with three tractor mounting plates, which are arranged in a triangle. The tractor towing is more stable.

[0011] The clamping sections of the hydraulic push rod I and the hydraulic push rod II are threadedly connected to the machine tool mounting plate, which is convenient for subsequent maintenance and disassembly of the equipment.

[0012] The utility model realizes the position change of the machine frame relative to the fixed frame by driving the side shift cylinder to slide through the hydraulic cylinder, thereby realizing the relative displacement of the power machine connected to the machine frame and the working machine connected to the fixed frame, changing the width of the working machine, thereby realizing the precise adjustment of the position of the working machine to ensure the seamless connection of the working surface of the land.
