Description

Technical Field

[0001] The invention relates to a large hydraulic tipping plough frame. Background Art

[0002] With the rapid development of modern agriculture, the efficiency and scale of agricultural production are constantly improving, and the demand for agricultural machinery and equipment is also growing. Traditional agricultural farming methods can no longer meet the needs of large-scale and efficient agricultural production. Therefore, the application of large-scale agricultural machinery and equipment has become an important direction for the development of modern agriculture.

[0003] In agricultural production, soil compaction is a common problem that seriously affects the growth and yield of crops. Soil compaction can cause the soil to become compact and the air permeability to become poor, making it difficult for the roots to penetrate the soil to absorb nutrients and water, thus affecting the normal growth of crops. In order to solve this problem, farmers need to take some effective measures to improve the soil structure and increase the air permeability and water retention capacity of the soil.

[0004] However, traditional agricultural farming methods often fail to achieve the desired results. Therefore, our company has designed and manufactured a large hydraulic flip plow frame in response to the actual needs of current agricultural production. This frame not only has powerful flipping and plowing capabilities, which can effectively solve the problem of soil compaction, but also has high flexibility and adaptability, and can adapt to different soil types and farming conditions. Summary of the invention

[0005] The purpose of the present invention is to solve the above deficiencies in the prior art and provide a large hydraulic tipping plow frame.

[0006] A large hydraulic reversible plow frame, comprising a front bracket, a main frame, a connecting seat, a first hydraulic cylinder, and a second hydraulic cylinder. The front bracket is provided with a connecting mechanism connected to a tractor, the connecting seat is provided with a connecting shaft, the connecting shaft is rotatably connected to the rear of the front bracket, the connecting seat is connected to the front end of the main frame through a connecting rod, and the two ends of the connecting rod are respectively hinged to the connecting seat and the main frame;

[0007] The base of the first hydraulic cylinder is installed at the upper end of the front bracket, and its floating joint is connected to the rear end of the connecting seat. The base of the second hydraulic cylinder is installed at the front end of the connecting seat, and the floating joint of the second hydraulic cylinder is connected to the main frame. The main frame is provided with multiple main plow frames and auxiliary plow frames. The main plow frames and auxiliary plow frames are symmetrically arranged with the main frame as the center line. The main plow frames and auxiliary plow frames are used to install the fence plow.

[0008] Furthermore, the connecting mechanism includes a suspension rod, which passes through the bottom of the front bracket and is used to be connected to the tractor. The upper section of the front bracket is provided with a plurality of connection holes, and the connection holes are used to connect the floating joint of the tractor lifting cylinder.

[0009] Furthermore, a first connecting plate extends from the upper outer surface of the main frame, the floating joint of the second hydraulic cylinder is connected to the first connecting plate, and a retractable supporting leg is also connected to the first connecting plate.

[0010] Furthermore, an angle-adjusting telescopic rod is provided between the connecting seat and the main frame, and two ends of the angle-adjusting telescopic rod are respectively hinged to the connecting seat and the main frame.

[0011] Furthermore, a reinforcing rod is provided between the first connecting plate and the main frame.

[0012] Furthermore, a second connecting plate is provided at both ends of the main frame, and the second connecting plate is used to connect with the auxiliary frame. The end of the auxiliary frame is provided with a second connecting plate, multiple main plow frames, and auxiliary plow frames. The main frame and the second connecting plate of the auxiliary frame are fixedly connected by multiple bolts.

[0013] Furthermore, the second connecting plate is obliquely disposed at the end of the main frame or the auxiliary frame.

[0014] Furthermore, the first hydraulic cylinder is equipped with a control valve, and the second hydraulic cylinder is equipped with a hydraulic lock.

[0015] Furthermore, the main plow frame is fixedly connected to the main frame via two mounting plates, and the mounting plates are L-shaped bending structures, which include a straight section and a vertical section. The vertical sections of the two mounting plates are respectively fixedly connected to the two side end surfaces of the main frame, and the straight sections of the two mounting plates are fixedly connected to the main plow frame.

A rotating shaft is rotatably connected in the axle mounting seat, one end of the rotating shaft is rotatably connected to one end of the wheel bracket, and the other end of the wheel bracket is connected to the wheel assembly. One end of the third connecting plate is connected to the axle mounting seat, and the other end is connected to the main frame. The main frame is located on the side away from the plowing device.

[0017] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0018] Stable and flexible structure: Through the ingenious design of the front bracket, main frame, connecting seat, connecting rod and other components, the overall structure of the frame is stable and can be flexibly flipped and adjusted. The two ends of the connecting rod are respectively hinged to the connecting seat and the main frame, so that the frame can maintain stable connection and rotation during the flipping process.

[0019] Easy to connect with the tractor: The design of the connecting mechanism enables the frame to be easily connected to the tractor. At the same time, the setting of the connecting hole also facilitates the connection of the floating joint of the tractor lifting cylinder, thereby realizing the lifting and lowering control of the frame.

[0020] Stable hydraulic drive: The configuration of the first hydraulic cylinder and the second hydraulic cylinder enables the rack to be turned and adjusted stably. The first hydraulic cylinder is responsible for promoting the relative rotation between the connecting seat and the main frame, while the second hydraulic cylinder is responsible for adjusting the angle of the main frame. The configuration of hydraulic locks and control valves further improves the stability and safety of the hydraulic system.

[0021] Reasonable plow frame setting: The main plow frame and the auxiliary plow frame are symmetrically arranged with the main frame as the center line, which not only improves the plowing efficiency but also ensures the plowing quality. At the same time, the main plow frame and the auxiliary plow frame are fixedly connected to the main frame through the mounting plate, making the plow frame structure more stable.

[0022] Easy angle adjustment: The setting of the angle-adjustable telescopic rod enables the angle between the connecting seat and the main frame to be easily adjusted to meet different plowing needs.

[0023] Strengthen the structural strength: A reinforcing rod is provided between the first connecting plate and the main frame, which improves the overall structural strength of the frame. At the same time, the design of the second connecting plate also makes the connection between the main frame and the auxiliary frame more stable.

[0024] Practical support wheel structure: The support wheel structure allows the frame to remain stable during flipping and adjustment, avoiding direct contact between the frame and the ground, thereby extending the service life of the frame. At the same time, the support wheel structure is located on the side away from the plowing device, avoiding interference with the frame during the plowing process. BRIEF DESCRIPTION OF THE DRAWINGS
