[0003] The present application aims at the defects and deficiencies of the prior art, and provides a combined land preparation machine tire smearing mechanism.

[0004] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is: a combined land preparation machine tire smearing mechanism, which comprises a combined land preparation machine, and the innovation point is that it further comprises an oil cylinder, a pull rod, a connecting rod and a smearing plate; the oil cylinder, the pull rod and the connecting rod are hingedly arranged below the frame of the combined land preparation machine, the oil cylinder is located between the pull rod and the connecting rod, the piston rod of the oil cylinder and the other end of the pull rod are hingedly arranged at the front of the smearing plate, and form a V-shaped structure therebetween, the oil cylinder and the connecting rod are the same hinged point, and the other end of the connecting rod is hingedly arranged at the tail end of the smearing plate.

[0005] Further, the smearing plate is in a triangular structure as a whole.

[0006] Further, the oil cylinder adjusts the height of the smearing plate.

[0007] Further, the connecting rod adjusts the angle of the smearing plate.

[0008] Further, the connecting rod is a pair of connecting rods, which are respectively located on the left and right sides of the smearing plate.

[0009] Further, the oil cylinder and the pull rod are located in the middle of the smearing plate.

[0010] Further, the power source of the oil cylinder comes from the hydraulic system of an external tractor.

[0011] After adopting the above structure, the present application has the following beneficial effects:

[0012] The present application can smear the tractor tire mark before the land preparation machine performs land preparation, reduce the amplitude of the land preparation machine during operation, and improve the land preparation quality by setting the smearing plate. BRIEF DESCRIPTION OF DRAWINGS

[0017] The application will be further described below with reference to the drawings.

[0018] In order to make the purpose, technical scheme and advantages of the application more clear, the application will be further described below with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the application and not to limit the application.

[0019] Reference Figs. 1-2 A combined land machine tire screed mechanism, comprising a combined land machine 1, further comprising an oil cylinder 2, a pull rod 3, a connecting rod 4 and a screed plate 5; the oil cylinder 2, the pull rod 3 and the connecting rod 4 are hingedly arranged below the frame of the combined land machine 1, the oil cylinder 2 is located between the pull rod 3 and the connecting rod 4, the piston rod of the oil cylinder 2 and the other end of the pull rod 3 are hingedly arranged at the front of the screed plate 5, and a V-shaped structure is formed therebetween, the oil cylinder 2 and the connecting rod 3 are the same hinged point, and the other end of the connecting rod 3 is hingedly arranged at the tail end of the screed plate 5. Specifically, the screed plate 5 can be lowered by the oil cylinder 2 and the connecting rod 4, the height and angle of the screed plate 5 can be adjusted, so that the screed plate 5 can be in contact with the ground, and during the walking process of the tractor, the screed plate 5 is located at the rear end of the tractor, so that the tire marks of the tractor can be smoothed, the amplitude of the land machine during operation is reduced, and the land leveling quality is improved.

[0020] In this embodiment, the screed plate 5 is in a triangular structure as a whole, which reduces the resistance and is beneficial to the walking of the screed plate 5.

[0021] In this embodiment, the oil cylinder 2 adjusts the height of the screed plate 5. The extension and retraction of the piston rod of the oil cylinder 2 adjusts the height of the front end of the screed plate 5.

[0022] In this embodiment, the connecting rod 4 adjusts the angle of the screed plate 5. Since the front end of the screed plate 5 is adjusted in height under the action of the oil cylinder, the tail end of the screed plate 5 is adjusted in angle under the action of the connecting rod 4.

[0023] In this embodiment, the connecting rod 4 is a pair of connecting rods, which are respectively located on the left and right sides of the screed plate 5, thereby improving the stability of the screed plate 5.

[0024] In this embodiment, the oil cylinder 2 and the pull rod 3 are located in the middle of the screed plate 5, which is beneficial to the adjustment of the height of the screed plate.

[0025] In this embodiment, the power source of the oil cylinder 2 comes from the hydraulic system of the external tractor, so that no additional power is needed, thereby reducing the cost.

[0026] The above merely aims to explain the technical solutions of the present application but not to limit the present application, and any other modifications or equivalent replacements made by those skilled in the art to the technical solutions of the present application should be included in the scope of claims of the present application as long as they are not deviated from the spirit and scope of the technical solutions of the present application.
