Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a flip plow, and more specifically to a double-lever type hydraulic buffer protection plowshare device. Background Art
[0002] The reversible plow is an agricultural machine that loosens the soil by turning it over with a plowshare, and the tillage depth can reach 25 to 40 centimeters or more. In the process of turning the soil with the plowshare, the plowshare will touch obstacles such as large rocks or tree roots in the soil. In the rigid connection state, the plowshare is hard-connected to the plywood plow beam, etc., and when encountering a large collision force, the bolts will break. In severe cases, it will cause the agricultural machinery to deform or damage the agricultural machinery. After long-term tillage, other parts of the agricultural machinery will also become loose and damaged. It takes a long time to replace parts and bolts, which reduces the working efficiency. In order to solve the occurrence of accidental events in the above process, a device is needed to buffer the impact force of the plowshare. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a double-lever type hydraulic buffer protection plowshare device, which buffers the impact force of the plowshare and avoids damage to the agricultural machinery.
[0004] In order to solve the above technical problems, the technical solutions adopted by the present utility model are as follows.
[0005] A double-lever hydraulic buffer protection plowshare device comprises plowshares installed on both sides of the rear end of a plowshare clamp, a mounting plate for mounting the plowshare clamp on a power machine is arranged at the front end of the plowshare clamp; the front end of the plowshare clamp is arranged in the middle of the mounting plate through a rotating shaft, a hydraulic buffer cylinder is arranged inside the plowshare clamp, two levers are arranged on the telescopic rod of the hydraulic buffer cylinder, the ends of the two levers are respectively arranged on both sides of the rear end of the mounting plate through the lever rotating shaft, and a hydraulic accumulator for providing hydraulic oil to the hydraulic buffer cylinder is connected to the hydraulic buffer cylinder.
[0006] To further optimize the technical solution, the front end of the plowshare clamp is connected to the middle of the mounting plate through two upper and lower connecting plates through a rotating shaft, and the lever is located between the two connecting plates.
[0007] To further optimize the technical solution, auxiliary plowshares are respectively arranged on both sides of the plowshare clamp located at the front end of the plowshare.
[0008] To further optimize the technical solution, the hydraulic buffer cylinder and the hydraulic accumulator are connected via an oil pipeline.
[0009] Due to the adoption of the above technical scheme, the technical progress achieved by the present invention is as follows.
[0010] The utility model provides a double-lever type hydraulic buffer protection plowshare device. When the plowshare is subjected to impact force, the impact force is transmitted to the hydraulic buffer cylinder through the lever, so as to buffer the impact force and slowly lift the plowshare, thereby preventing the plowshare from being damaged due to excessive impact force, thereby improving working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a top view of the utility model.
[0013] Among them: 1. hydraulic accumulator, 2. hydraulic buffer cylinder, 3. lever, 4. plowshare, 5. auxiliary plowshare, 6. plowshare splint, 7. rotating shaft, 8. lever rotating shaft, 9. oil pipeline, 10. mounting plate. DETAILED DESCRIPTION
[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0015] A double-lever hydraulic buffer protection plowshare device, combined with Figure 1 to Figure 2 As shown, it includes a plowshare clamp 6, plowshares 4 are arranged on both sides of the rear end of the plowshare clamp 6, auxiliary plowshares 5 are arranged on both sides of the plowshare clamp 6 located at the front end of the plowshare 4, and a mounting plate 10 is arranged at the front end of the plowshare clamp 6 for mounting the plowshare clamp on a power machine, so that the auxiliary plowshare and the plowshare are driven by the power machine to turn over the soil.
[0016] The front end of the plowshare clamp 6 is two clamps opened forward, and the ends of the two clamps are connected to the upper and lower sides of the middle of the mounting plate 10 through the rotating shaft 7 respectively. When the plowshare is hit, the plowshare clamp can be lifted up and down through the rotating shaft 7.
[0017] A hydraulic buffer cylinder 2 is arranged inside the plowshare clamp 6, and two levers 3 are arranged on the telescopic rod of the hydraulic buffer cylinder 2. The two levers 3 are opened to the left and right sides, and the levers 3 are located between the two connecting plates on the plowshare clamp. The ends of the two levers 3 are respectively arranged on both sides of the rear end of the mounting plate 10 through the lever shaft 8. When the plowshare clamp is subjected to force and causes the plowshare clamp to be lifted upward, the force on the lever is transmitted to the hydraulic buffer cylinder to buffer the impact force of the plowshare.
[0018] The hydraulic buffer cylinder 2 is connected to a hydraulic accumulator 1 via an oil pipe 9 for providing hydraulic oil to the hydraulic buffer cylinder 2. The oil pipe can circulate the hydraulic oil in the hydraulic buffer cylinder and the hydraulic oil in the hydraulic accumulator.
[0019] When the utility model is working, nitrogen of a certain pressure is first charged into the hydraulic accumulator, and hydraulic oil of a certain pressure is charged into the hydraulic accumulator and the hydraulic buffer cylinder before the plowshare turns the soil. In the process of the plowshare turning the soil, when the plowshare encounters a large impact force, the plowshare clamping plate drives the plowshare to be lifted upward around the rotating shaft, and then the collision force is transmitted to the hydraulic buffer cylinder through the lever, the pressure in the hydraulic buffer cylinder increases, the hydraulic oil in the hydraulic buffer cylinder is squeezed toward the hydraulic accumulator, the lever is lifted upward around the lever rotating shaft, and the plowshare is buffered and lifted at the same time.
[0020] When the plowshare passes over an obstacle or the collision force decreases, the hydraulic accumulator squeezes the hydraulic oil back into the hydraulic buffer cylinder, the lever moves downward under force, and the plowshare returns to its original position.
