[0023] 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.
[0024] Example 1
[0025] Please see Figure 1-4 In this embodiment: a grass-pressing structure for a lawnmower includes a base 1, a grass-cutting component 2 is mounted on one side of the surface of the base 1, a fixing frame 5 is fixedly connected to the other side of the surface of the base 1, a height adjustment component 6 is mounted on one side of the fixing frame 5, a mounting base 3 is mounted at the bottom of the height adjustment component 6, a grass-pressing plate 4 is mounted on one side of the mounting base 3, and a positioning component 7 is mounted on one side of the height adjustment component 6.
[0026] The height adjustment assembly 6 includes a fixed cylinder 601, the outer wall of which is fixedly connected to one side of the fixed frame 5. A screw 602 is rotatably connected to the top of the inner part of the fixed cylinder 601. A lifting cylinder 603 is threadedly connected to the outer wall of the screw 602. The outer wall of the lifting cylinder 603 is slidably connected to the inner wall of the fixed cylinder 601. The upper surface of the mounting base 3 is fixedly connected to the bottom end of the lifting cylinder 603. A rotating rod 605 is rotatably connected to the upper part of one side of the fixed cylinder 601. A driving bevel gear 606 is fixedly connected to one end of the rotating rod 605. A driven bevel gear 604 is fixedly connected to the top of the screw 602. The driven bevel gear 604 meshes with the driving bevel gear 606. A turntable 607 is fixedly connected to the other end of the rotating rod 605.
[0027] The positioning component 7 includes a positioning hole 701 and a connecting hole 704. The positioning hole 701 is opened on the lower part of one side of the fixed cylinder 601, and the connecting hole 704 is opened on one side of the outer wall of the lifting cylinder 603. The positioning rod 703 is engaged on the inner wall of the positioning hole 701 and the connecting hole 704.
[0028] In this embodiment, the lawn or weeds are cut by the mowing assembly 2. When the mowing assembly 2 is working, the grass pressing plate 4 is pressed against the weeds to flatten them, making cutting easier. By operating the turntable 607, the rotating rod 605 is driven to rotate. The driving bevel gear 606 on the rotating rod meshes with the driven bevel gear 604 on the screw 602, causing the screw 602 to rotate. The rotation of the screw 602 drives the lifting cylinder 603, which is threaded to it, to move up and down, thereby adjusting the height of the mounting base 3. This allows for precise adjustment of the height of the grass pressing plate 4 to meet the needs of different terrains and lawn heights. After the height adjustment is completed, the positioning rod 703 fixes the lifting cylinder 603 at the required height position through the cooperation of the positioning hole 701 and the connecting hole 704, ensuring stability during operation.
[0029] Furthermore, the mowing assembly 2 includes a mower 201, one side of which is fixedly connected to one side of the surface of the base 1, and a mowing blade 202 is fixedly connected to the output end of the mower 201.
[0030] In this process, by activating the lawnmower 201, the lawnmower 201 outputs power to make the mowing blade 202 rotate at high speed, thereby achieving efficient cutting of lawn or weeds.
[0031] Furthermore, guide grooves 608 are provided on both sides of the inner wall of the fixed cylinder 601, and guide blocks 609 are fixedly connected to both sides of the outer wall of the lifting cylinder 603. The outer wall of the guide block 609 is slidably connected to the inner wall of the guide groove 608.
[0032] With the guide block 609 and guide groove 608, the lifting cylinder 603 can move in a straight line when it moves.
[0033] Furthermore, a fixing sleeve 702 is fixedly connected to the lower part of one side of the fixing cylinder 601, the outer wall of the positioning rod 703 is slidably connected to the inner wall of the fixing sleeve 702, and a spring 705 is sleeved on the outer wall of the positioning rod 703. One end of the spring 705 is fixedly connected to one side of the inner wall of the fixing sleeve 702, and the other end of the spring 705 is fixedly connected to one end of the positioning rod 703.
[0034] The positioning rod 703 is kept in an elastic connection by the action of the spring 705, which makes it convenient for the operator to quickly lock or unlock.
[0035] Furthermore, buffer telescopic rods 8 are fixedly connected to both sides of the outer wall of the mounting base 3, and one end of the buffer telescopic rod 8 is fixedly connected to the inner side of the straw pressing plate 4.
[0036] The inner side of the grass pressing board 4 is fixedly connected to a buffer telescopic rod 8. When the grass pressing board 4 comes into contact with the ground or lawn, the buffer telescopic rod 8 can absorb part of the impact force, protect the grass pressing board 4 from damage, and make the grass pressing process smoother and reduce damage to the ground.
[0037] Furthermore, four corners of the lower surface of the base 1 are fixedly connected with traveling wheels 9; handles 10 are fixedly connected to both sides of the upper surface of the base 1.
[0038] The lawnmower is equipped with wheels 9, which allow it to move smoothly and adapt to different terrains. The handle 10 makes it easy for the operator to push or control the lawnmower, improving operating comfort and flexibility.
[0039] Preferably, the straw pressing board 4 is arc-shaped;
[0040] The design of the grass pressing board 4 as an arc shape helps to improve the flatness of the lawn while reducing resistance and damage to the ground.
[0041] The working principle and usage process of this utility model are as follows: The operator starts the lawnmower 201, which outputs power to make the mowing blade 202 rotate at high speed, thereby achieving efficient cutting of lawn or weeds. When the mowing blade 201 is working, the grass pressing plate 4 is close to the weeds, flattening them and making cutting easier. By operating the turntable 607, the rotating rod 605 is driven to rotate. The driving bevel gear 606 on the rotating rod meshes with the driven bevel gear 604 on the screw 602, causing the screw 602 to rotate. The rotation of the screw 602 drives the lifting cylinder 603, which is threadedly connected to it, to move up and down, thereby adjusting the height of the mounting base 3 and thus achieving precise adjustment of the height of the grass pressing plate 4 to meet the needs of different terrains and lawn heights. After the height adjustment is completed, the positioning rod 703 fixes the lifting cylinder 603 at the required height position through the cooperation of the positioning hole 701 and the connecting hole 704, ensuring stability during operation.
[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
