Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an adjustable anti-splash cover structure for a lawn mower. Background Technology
[0002] Existing lawnmower guards are mostly fixed structures, making it difficult to flexibly adjust the protective range according to the height of the grass stalks and the working scene. This can easily lead to problems such as grass clippings flying and injuring people, and excessive protection affecting operation. In addition, they have poor adaptability to different terrains. There is an urgent need for an adjustable structure to optimize the protective effect and improve the safety and convenience of operation.
[0003] In existing technologies, traditional static protective covers are inconvenient to operate in narrow spaces because their fixed structure prevents volume adjustment; and they are also inadequate in controlling dynamic splashes because they cannot cope with the irregular splashes generated by high-speed grass-cutting modules and have gaps.
[0004] Therefore, an adjustable anti-splash guard structure for lawn mowers is proposed. Utility Model Content
[0005] The purpose of this invention is to provide an adjustable anti-splash cover structure for a lawn mower, which can solve the problems of insufficient dynamic splash control in existing narrow space operations.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable anti-splash cover structure for a lawn mower, comprising an upper rod body, a connecting handle fixedly connected to the bottom of the upper rod body, a lower rod body fixedly connected to the bottom of the connecting handle, a lawn mowing module movably connected to the bottom of the lower rod body, an adjustable protective mechanism movably connected to the outer side of the lower rod body, a dynamic protective component movably connected to the outer side of the adjustable protective mechanism, the adjustable protective mechanism including a support ring, the support ring being rotatably connected to the outer side of the lower rod body, a petal-shaped protective cover rotatably connected to the outer side of the support ring, a drive ring rotatably connected to the outer side of the lower rod body, the drive ring being disposed on the side of the support ring away from the lawn mowing module, and an adjustment component movably connected to the opposite side of the support ring and the drive ring.
[0007] Preferably, the dynamic protection component includes a servo motor, which is fixedly connected to the outside of the connecting handle, and a speed controller is fixedly connected to the outside of the output end of the servo motor.
[0008] Preferably, a drive gear is fixedly connected to the output end of the speed regulator.
[0009] Preferably, the drive gear is meshed with a linkage gear on its outer side, the linkage gear is rotatably connected to the outer side of the lower rod body, and the linkage gear is fixedly connected to the drive ring on the side near the connecting handle.
[0010] Preferably, the adjustment assembly includes an electronic telescopic rod, which is fixedly connected to the side of the drive ring away from the connecting handle, and a linkage ring is fixedly connected to the other end of the electronic telescopic rod, which is located on the outside of the lower rod body.
[0011] Preferably, a linkage rod is rotatably connected to the side of the linkage ring near the petal-shaped protective cover, and the other end of the linkage rod is rotatably connected to the side of the petal-shaped protective cover near the linkage ring.
[0012] Preferably, a cutting plate is fixedly connected to the front side of the flap-shaped protective cover.
[0013] Preferably, a main grip is fixedly connected to the top of the upper rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application, by setting an adjustable protective mechanism, can drive the linkage ring through an electronic telescopic rod to rotate and adjust the shape of the petal-shaped protective cover. This not only improves the protective flexibility and adaptability during lawn mower operation, but also enhances the ease of operation. It solves the traditional problems through the dynamic adjustment of the petal-shaped protective cover. When operating in narrow spaces such as flower beds and walls, the extension of the electronic telescopic rod causes the protective cover to flip towards the lawn mowing module to form a gathered pocket shape, reducing the overall protective volume to adapt to narrow environments. The extended inclined plate state ensures protection during normal operation, avoiding the problems of traditional static protective covers that cannot be adjusted due to their fixed structure, which are easily obstructed and inconvenient to operate in narrow spaces. 2. This application enhances the control of irregular splashes by setting up dynamic protection components, and effectively avoids the problem of debris escaping from the gaps. It drives the drive ring to rotate by driving the linkage gear through the drive gear, and then pulls the petal-shaped protective cover to rotate around the axis through the linkage rod. With the speed regulator at the output of the servo motor, the speed can be adjusted throughout the process, forming a dynamically adjustable protective barrier. It can adapt to the irregular splash trajectory generated by the high-speed grass trimming module in real time, fill the gaps and loopholes of static protection, and solve the problem of insufficient dynamic splash control.

[0017] 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.
[0018] Please see Figure 1-4 The present invention provides the following technical solution: An adjustable splash guard structure for a lawn mower includes an upper rod 1, a connecting handle 2 fixedly connected to the bottom of the upper rod 1, a lower rod 3 fixedly connected to the bottom of the connecting handle 2, a mowing module 4 movably connected to the bottom of the lower rod 3, an adjustable protective mechanism 5 movably connected to the outer side of the lower rod 3, and a dynamic protective component 6 movably connected to the outer side of the adjustable protective mechanism 5. The adjustable protective mechanism 5 includes a support ring 51, which is rotatably connected to the outer side of the lower rod 3. A petal-shaped protective cover 52 is rotatably connected to the outer side of the support ring 51, and a drive ring 53 is rotatably connected to the outer side of the lower rod 3. The drive ring 53 is located on the side of the support ring 51 away from the mowing module 4. An adjustment component 54 is movably connected to the opposite side of the support ring 51 and the drive ring 53.
[0019] In this embodiment: an integrated adjustable protective structure is provided on the outside of the grass cutter composed of the grass cutting module 4, the lower rod 3, the connecting handle 2 and the upper rod 1. This structure includes a petal-shaped protective cover 52 supported by a support ring 51, which is arranged in an array on the outside and unfolds like a petal. Each petal is rotatably connected to the outside of the support ring 51. During use, its state can be adjusted by adjusting the component 54 to adapt to different working conditions and special directions of debris splashing, thereby improving convenience and protection.
[0020] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the dynamic protection component 6 includes a servo motor 61, which is fixedly connected to the outside of the connecting handle 2. A speed regulator 62 is fixedly connected to the outside of the output end of the servo motor 61.
[0021] Specifically, such as Figure 1, Figure 2 , Figure 4 As shown, a drive gear 63 is fixedly connected to the output end of the speed regulator 62.
[0022] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a linkage gear 64 is meshed with the outer side of the drive gear 63. The linkage gear 64 is rotatably connected to the outer side of the lower rod body 3, and the linkage gear 64 is fixedly connected to the drive ring 53 on the side near the connecting handle 2.
[0023] In this embodiment: by setting a servo motor 61 at the outer end of the connecting handle 2, the drive gear 63 drives the linkage gear 64 to make the drive ring 53 with the electronic telescopic rod 5401 rotate along the outer side of the lower rod body 3, thereby driving the linkage ring 5402 on the outer side of the lower rod body 3. The linkage ring 5402 pulls the axis of the petal-shaped protective cover 52 to rotate through the linkage rod 5403, and the speed regulator 62 on the outer side of the output end of the servo motor 61 realizes full-range speed regulation, so that the petal-shaped protective cover 52 provides dynamic protection, which not only forms a dynamic barrier to reduce splashing, but also prevents debris from escaping through gaps, thereby solving the problem of insufficient dynamic splash control caused by irregular splashing and gaps in the high-speed grass cutting module 4.
[0024] Specifically, such as Figure 3 As shown, the adjustment assembly 54 includes an electronic telescopic rod 5401, which is fixedly connected to the drive ring 53 on the side away from the connecting handle 2, and the other end of the electronic telescopic rod 5401 is fixedly connected to a linkage ring 5402, which is located on the outside of the lower rod body 3.
[0025] Specifically, such as Figure 3 As shown, a linkage rod 5403 is rotatably connected to the side of the linkage ring 5402 near the petal-shaped protective cover 52, and the other end of the linkage rod 5403 is rotatably connected to the side of the petal-shaped protective cover 52 near the linkage ring 5402.
[0026] In this embodiment: by adjusting the electronic telescopic rod 5401 on the outside of the drive ring 53, when it is extended, the linkage ring 5402 is driven to move closer to the support ring 51. The linkage rod 5403 on the outside of the linkage ring 5402 pushes the petal-shaped protective cover 52 to flip towards the grass cutting module 4 into a gathered pocket shape. When it is shortened, it rotates in the opposite direction into an extended inclined plate shape. This can adapt to different working conditions and special directions of debris splashing, improving convenience and protection.
[0027] Specifically, such as Figure 1 , Figure 2 As shown, a cutting plate 7 is fixedly connected to the front side of the flap-type protective cover 52.
[0028] Specifically, such as Figure 1 , Figure 2As shown, the top of the upper rod 1 is fixedly connected to the main grip 8.
[0029] In this embodiment: the cutting plate 7 can cut debris by its front groove when the petal-shaped protective cover 52 rotates, thereby improving the grass cutting and protection effects. The main handle 8 can further facilitate operation.
[0030] Working Principle: When the lawn mower is performing lawn mowing operations, to prevent grass clippings, mud, stones, etc., from being splashed and injuring the operator due to inertia under the high-speed drive of the mowing module 4, a protective cover is usually installed to shield the operator. However, existing protective covers are usually static and fixed, resulting in significant limitations in protection. To overcome these limitations, an adjustable protective structure is now installed on the outside of the lawn mower, which consists of the mowing module 4, the lower rod 3, the connecting handle 2, and the upper rod 1. This structure is integrated into the outside of the lower rod 3, which houses the mowing module 4. An array of petal-shaped protective covers 52, supported by a support ring 51, is provided on the outer side. These petals unfold like petals, each rotatably connected to the outer side of the support ring 51. During use, their operational state can be adjusted. By adjusting the electronic telescopic rod 5401 located outside the drive ring 53, when the electronic telescopic rod 5401 extends, it drives the linkage ring 5402 closer to the support ring 51. This, in turn, rotates and pushes the petal-shaped protective covers 52 via the linkage rod 5403 outside the linkage ring 5402, causing them to flip towards the grass-cutting module 4, forming a gathered pocket state. Conversely, they flip towards the opposite side. The shape of the extended inclined plate is formed by rotation, which can be adjusted to adapt to different working conditions, such as narrow flower beds and fences, and can also deal with debris flying from special directions, thereby improving convenience and protection. The petal-shaped protective cover 52 is no longer a static protection. A servo motor 61 is set at the outer end of the connecting handle 2 in a position that does not affect the grip. By driving the servo motor 61, the drive gear 63 located at the output end can be rotated. The drive gear 63 can drive the linkage gear 64, which is located on the outside of the drive ring 53 on which the electronic telescopic rod 5401 is mounted. The drive ring 53 drives the lower rod body. The outer rotation drives the linkage ring 5402 located on the outer side of the lower rod 3. The linkage ring 5402 is not connected to the lower rod 3. The linkage ring 5402 is connected to each petal of the petal-type protective cover 52 through the linkage rod 5403. Therefore, the petal-type protective cover 52 can be pulled to rotate around the axis. During this process, the speed can be adjusted throughout the entire process through the speed regulator 62 on the outer side of the output end of the servo motor 61. This enables dynamic protection, forming a dynamic barrier to further reduce splashing and preventing debris from escaping through the gaps in the petal-type protective cover 52. In summary, this optimizes the adjustable anti-splash cover for lawn mowers.
[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
