Description

Technical Field

[0001] This utility model belongs to the field of lawnmower technology, and in particular relates to a hydraulic mini lawnmower. Background Technology

[0002] A hydraulic mini lawnmower is a small lawnmower that uses a hydraulic power system to drive its cutting mechanism. It is suitable for small lawns or narrow spaces that are difficult to access. Its core feature is that it uses a hydraulic motor instead of a traditional electric or internal combustion engine power system to provide stable and powerful power output, which can efficiently drive the lawnmower's blades to mow the lawn.

[0003] In existing hydraulic mini lawnmowers, the cutting height of the blades usually needs to be adjusted according to the growth of different grass species to ensure an ideal lawn effect. However, existing hydraulic mini lawnmowers generally suffer from the problem of inconvenient blade height adjustment. This makes it difficult for users to flexibly adjust the cutting height of the blades when facing different lawn types or scenarios requiring different cutting heights. As a result, they cannot meet diverse mowing needs, reduce the ease of use and efficiency of the lawnmower, and further affect the overall user experience.

[0004] To address these issues, we provide a hydraulic mini lawnmower. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic mini lawnmower that, through the cooperation of the adjustment component and the chip-blocking component, solves the problem that existing hydraulic mini lawnmowers are inconvenient to adjust the height of the blade and cannot meet different mowing needs.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a hydraulic mini lawnmower, comprising a housing, a drive box fixedly connected to one side of the housing, and a blade disc disposed within the inner cavity of the housing; an adjustment assembly comprising a drive rod movably connected to the top of the drive box, a driven rod movably connected to the bottom of the drive box, one end of the driven rod being fixedly connected to one end of the blade disc, a drive pulley fixedly connected to the surface of the drive rod, and a driven pulley fixedly connected to the surface of the driven rod; a chip-blocking assembly comprising a positioning seat fixedly connected to the top of the housing, a bracket movably connected to the inner cavity of the positioning seat, a cover fixedly connected to the top of the bracket, and a cylinder movably connected to the top of the housing, the free end of the cylinder being movably connected to one side of the bracket.

[0008] The present invention is further configured such that the adjusting component includes a movable rod, the movable rod is slidably connected to one side of the inner cavity of the drive box, and a tensioning pulley is fixedly connected to the surface of the movable rod. The driving pulley, the driven pulley and the tensioning pulley are connected by belt drive.

[0028] Specifically: A ventilation opening is provided on one side of the drive box 2 to facilitate heat dissipation of the internal mechanical components. The rotating blade 3 can cut the grass on the surface of the lawn. One end of the driven rod 5 extends into the machine housing 1 and is fixed to one end of the blade 3. The other end slides against the inner wall of the drive box 2. One end of the blade 3 is slidably connected to one side of the inner cavity of the machine housing 1 to support and limit the driven rod 5. The cover 10 is used to block the flying grass clippings.

[0029] Example 2

[0030] Please see Figure 1-5 Based on Embodiment 1, the adjustment assembly further includes a movable rod 12, which is slidably connected to one side of the inner cavity of the drive box 2. A tension pulley 13 is fixedly connected to the surface of the movable rod 12. The driving pulley 6, the driven pulley 7, and the tension pulley 13 are connected by belt drive. A support plate 14 is fixedly connected to the inner cavity of the drive box 2. A hydraulic cylinder 15 is fixedly connected to the inner cavity of the support plate 14. A retainer 16 is fixedly connected to the free end of the hydraulic cylinder 15. The inner cavity of the retainer 16 is movably connected to the surface of the driven rod 5. A spring is fixedly connected to the inner cavity of the drive box 2. A spring rod 17 has a spring rod 17 with a pull sleeve 18 fixedly connected to its free end. The inner cavity of the pull sleeve 18 is movably connected to one side of the surface of the moving rod 12. A piston motor 19 is fixedly connected to one side of the drive box 2. The output end of the piston motor 19 is fixedly connected to one end of the drive rod 4. A sliding groove is provided on one side of the inner cavity of the drive box 2. The surface of the driven rod 5 is slidably connected to the inner cavity of the sliding groove. Adaptation grooves are provided on both sides of the inner cavity of the drive box 2. One end of the moving rod 12 is slidably connected to the inner cavity of the adaptation groove. A roller 20 is movably connected to one side of the inner cavity of the housing 1. A movable seat 21 is fixedly connected to the bottom of the housing 1.

[0031] Specifically: the moving rod 12 moves inside the drive box 2, and is limited by the inner wall of the drive box 2, allowing it to slide inside the drive box 2. The driving pulley 6, the driven pulley 7, and the tension pulley 13 are connected by a belt. The plunger motor 19 drives the cutter head 3 to rotate hydraulically. The slide groove allows the driven rod 5 to connect with the cutter head 3, and allows the driven rod 5 to move the cutter head 3 up and down, making it easy to adjust the height of the cutter head 3. The roller 20 and the moving seat 21 enable the machine housing 1 to move normally, and a push handle is fixedly connected to one side of the top of the machine housing 1.

[0032] The working principle of this utility model is as follows: When the hydraulic mini lawnmower is needed, the height of the cutter head 3 is first adjusted as needed. The hydraulic cylinder 15 is started by the external controller. The hydraulic cylinder 15 drives the sleeve 16 at its free end to move. The sleeve 16 drives the driven rod 5 to move. The driven rod 5 drives the cutter head 3 to move, so that the cutter head 3 can be moved to a suitable height. When the driven rod 5 moves, the spring rod 17 can drive the pulling sleeve 18 at its free end to move through its own elasticity. The pulling sleeve 18 drives the moving rod 12 to move. The moving rod 12 drives the tensioning pulley 13 to move. The movement of the tensioning pulley 13 keeps the driving pulley 6, the driven pulley 7 and the belt on the surface of the tensioning belt in a taut state, which will not affect the subsequent operation of the cutter head 3.

[0033] Then, the cylinder 11 is started by the external controller. The cylinder 11 drives the bracket 9 to swing at an angle, and the bracket 9 drives the cover 10 to swing at an angle. The angle of the cover 10 is adjusted according to the height of the cutter head 3 to ensure that grass clippings will not fly and injure people. Finally, the plunger motor 19 is started by the external controller. The plunger motor 19 drives the drive rod 4 to rotate, and the drive rod 4 drives the drive pulley 6 to rotate. The drive pulley 6 drives the driven rod 5 to rotate through the driven pulley 7. The driven rod 5 drives the cutter head 3 to rotate, so that the cutter head 3 can perform grass cutting.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.
