[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a lawn mowing and cleaning device for agricultural and forestry use, such as... Figure 1 — Figure 6As shown, the lawn mower includes a main body 1, on which an installation groove 11 is provided, and a telescopic component is provided in the installation groove 11. A connecting frame 5 is provided on the telescopic component, and a connecting frame 52 is suspended at the bottom of the connecting frame 5 through an elastic connecting component. Multiple sets of flattening wheels 3 are installed at the bottom of the connecting frame 52 in a horizontal direction. The wheel surfaces of the multiple sets of flattening wheels 3 are provided with anti-slip ridges, which are used to roll and flatten the lawn before mowing, so as to facilitate subsequent mowing. The elastic connecting component is used to buffer the impact force received by the connecting frame 52 during the flattening operation and realize the adaptive extension and retraction of the connecting frame 52 with the undulation of the lawn.

[0026] The mounting slot 11 is fixedly installed with a fixing plate 42. The telescopic assembly includes a cylinder 4 fixedly installed in the mounting slot 11, and a push rod 41 is fixedly connected to the output end of the cylinder 4. The push rod 41 passes through the fixing plate 42, and the end of the push rod 41 is fixedly connected to the connecting frame 5. The cylinder 4 serves as a power source, transmitting power through the push rod 41 to realize the telescopic movement of the connecting frame 5. Two sets of limiting rods 43 are slidably installed on the upper part of the fixing plate 42. The ends of the two sets of limiting rods 43 are fixedly connected to the side wall of the connecting frame 5. The limiting rods 43 can limit the movement direction of the connecting frame 5, ensuring the stability and accuracy of the telescopic process, so that the telescopic assembly can work reliably.

[0027] The elastic connection component includes multiple sets of dampers 71 evenly distributed and fixedly installed between the bottom of the connecting frame 5 and the top of the connecting frame 52. The outer surface of each set of dampers 71 is coaxially fitted with a spring 7. The top of the spring 7 is fixedly connected to the bottom of the connecting frame 5, and the bottom of the spring 7 is fixedly connected to the top of the connecting frame 52. The combined design of the damper 71 and the spring 7 can effectively buffer the impact force on the connecting frame 52 during the flattening operation, reduce damage to the equipment, and utilize the elasticity of the spring 7 to allow the connecting frame 52 to adaptively expand and contract with the undulation of the lawn, ensuring that the flattening wheel 3 always has good contact with the lawn and improving the flattening effect.

[0028] The connecting frame 5 has horizontal guide rails 51 fixedly installed on both the left and right side walls. The inner walls of the mounting groove 11 have guide grooves that are compatible with the horizontal guide rails 51. The connecting frame 5 achieves smooth extension and retraction along the inner wall of the mounting groove 11 through the sliding cooperation between the horizontal guide rails 51 and the guide grooves. The cooperation between the horizontal guide rails 51 and the guide grooves provides precise guidance for the movement of the connecting frame 5, preventing it from deviating or shaking during the extension and retraction process, ensuring the stability and reliability of the extension and retraction action, and improving the overall stability of the equipment operation.

[0029] Vertical guide rails 6 are fixedly installed on both the left and right side walls of the connecting frame 52. Limiting grooves adapted to the vertical guide rails 6 are opened on the left and right inner side walls of the connecting frame 5. The connecting frame 52 realizes vertical extension and contraction along the inner wall of the connecting frame 5 through the sliding cooperation between the vertical guide rails 6 and the limiting grooves. The design of the vertical guide rails 6 and the limiting grooves ensures the movement accuracy of the connecting frame 52 in the vertical direction, limits its movement trajectory, and enables the connecting frame 52 to accurately realize adaptive extension and contraction, thereby better adapting to the undulations of the lawn surface and improving the working effect of the flattening roller 3.

[0030] The top of the lawn mower body 1 is bolted to a top plate 2. The bolted installation of the top plate 2 facilitates disassembly and maintenance, and makes it easy to inspect and repair the internal components. The top plate 2 is provided with a groove 21, which facilitates the handling or movement of the equipment and increases the ease of use and user-friendliness of the equipment.

[0031] Working principle: Before lawn mowing, the cylinder 4 in the telescopic assembly is driven to extend the push rod 41 at the output end vertically downward. Since the push rod 41 is fixedly connected to the connecting frame 5, and the connecting frame 5 slides with the guide groove on the inner wall of the mounting groove 11 through the horizontal guide rails 51 on both sides, the two sets of limit rods 43 on the fixed plate 42 rise and fall synchronously with the connecting frame 5 to limit its trajectory, so that the connecting frame 5 extends smoothly from the mounting groove 11 at the front end of the lawn mowing machine body 1. After the connecting frame 5 extends, the spring 7 in the elastic connecting assembly pushes the connecting frame 52 downward in its natural state. The connecting frame 52 slides with the limit groove on the inner wall of the connecting frame 5 through the vertical guide rails 6 on both sides, ensuring smooth vertical extension and contraction, and finally driving the multiple sets of flattening wheels 3 at the bottom to press against the lawn surface.

[0032] During operation, the main body 1 of the lawn mower is moved, and multiple sets of flattening rollers 3 are rolled by the friction between the anti-slip ridges on the roller surface and the lawn, pre-flattening and combing the fallen and messy grass. When encountering uneven areas of the lawn, the impact force on the flattening rollers 3 is transmitted to the elastic connecting component through the connecting frame 52. The spring 7 deforms to buffer the impact force, and at the same time, the damper 71 can suppress the excessive bounce of the spring 7, so that the connecting frame 52 can adaptively adjust with the undulation of the lawn, ensuring that the flattening rollers 3 are always in close contact with the lawn surface, thereby providing a flat cutting base for the subsequent cutting components and improving the uniformity and aesthetics of lawn cutting.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
