[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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a detachable grass trimmer head to prevent grass roots from splashing. (See also...) Figures 1 to 5 A detachable grass trimmer head that prevents grass roots from splashing includes a top cover 1 and two mounting components 10.

[0026] The bottom of the top cover 1 is fixedly connected to a hinge 2. The top cover 1 is hinged to a connecting plate 3 via the hinge 2. Multiple elastic bristles 4 are fixedly connected to the bottom surface of the connecting plate 3. The elastic bristles 4, the connecting plate 3, and the hinge 2 constitute a protective assembly. There are four protective assemblies, which are circumferentially distributed at equal angles at the bottom of the top cover 1. An opening is provided at the center of the top cover 1, and a bearing 5 is embedded in the opening. A connecting shaft 6 is fitted inside the bearing 5. A coupling 7 is fitted at the top of the connecting shaft 6. A cutter 8 is installed at the bottom of the connecting shaft 6. Two transparent plates 9 are embedded through the top of the top cover 1 and are symmetrically distributed about the coupling 7.

[0027] The bottom of the top cover 1 is hinged by the connecting plate 3, which hangs down naturally. When the elastic bristles 4 touch the ground, they bend slightly to form a bottom sealing area, preparing for the subsequent splash protection function.

[0028] An external power source, such as a motor, is input via a coupling 7, which drives the connecting shaft 6 to rotate at high speed within the bearing 5. The bearing reduces rotational friction, and the cutter 8 at the bottom of the connecting shaft rotates at high speed to cut weeds. The transparent plate 9 on the top of the cover 1 allows the user to observe the operating status of the cutter and the cutting effect, facilitating real-time adjustments to the operation.

[0029] When the blade 8 cuts the weeds, the grass clippings are thrown around by centrifugal force. At this time, the elastic bristles 4 are in close contact with the ground, forming a flexible barrier. The elasticity of the bristles can adapt to the undulations of the ground and prevent the grass clippings from flying upwards.

[0030] The connecting plate 3 is hinged to the top cover via the hinge 2. If it encounters obstacles such as stones, the connecting plate 3 can swing upward to move the bristles to avoid them, thus preventing hard collisions that could damage the structure. After the obstacle passes, the bristles return to their elastic state and continue to maintain their anti-splash function.

[0031] Four protective components are distributed at equal angles at the bottom of the top cover 1, forming a 360° ring protection to ensure that grass clippings from all directions are effectively blocked.

[0032] Loosen bolt 1005 to slide mounting block 1004 out along slide groove 1002, enabling quick disassembly of the brush head from the equipment. If the elastic bristles wear down due to long-term use, the connecting plate 3 can be directly disassembled through hinge 2 to replace the new bristle assembly, resulting in low maintenance costs.

[0033] The mounting assembly 10 includes a fixing plate 1001. The top of the fixing plate 1001 has a sliding groove 1002 and a through groove 1003. A mounting block 1004 is slidably fitted in the sliding groove 1002. The top of the mounting block 1004 has a mounting groove 1006. The bottom of the mounting block 1004 has a threaded hole 1007. A bolt 1005 is threadedly fitted in the threaded hole 1007. The end of the bolt 1005 passes through the threaded hole 1007 and abuts against the inner wall of the sliding groove 1002. The nut end of the bolt 1005 overlaps the outer surface of the fixing plate 1001. The threaded end of the bolt 1005 passes through the through groove 1003. Two mounting blocks 1004 are respectively provided on the two fixing plates 1001.

[0034] The fixed plate 1001 serves as a mounting base, and the sliding groove 1002 and through groove 1003 on its top provide space for the mounting block 1004 to move. The mounting block 1004 is slid along the sliding groove 1002 to the target position so that the mounting groove 1006 is aligned with the equipment mounting hole.

[0035] The bolt 1005 passes through the through groove 1003 and is screwed into the threaded hole 1007 at the bottom of the mounting block 1004. After tightening the bolt 1005, the end of the bolt 1005 abuts against the inner wall of the slide groove 1002, thereby fixing the position of the mounting block 1004. Two mounting blocks 1004 are set on each of the two fixing plates 1001 to form a four-point fixing structure to ensure the stability of the grass trimmer after installation.

[0036] Working principle: The cutting head drives the blades to rotate and cut weeds through a power transmission system. At the same time, the protective components prevent grass roots from flying. With the help of adjustable mounting components, the equipment can be stably installed and its position can be adjusted. Specifically, external power such as a motor is transmitted to the connecting shaft 6 through the coupling 7, which drives the blades 8 to rotate at high speed to complete the cutting.

[0037] The elastic bristles 4 at the bottom of the top cover 1 form a flexible barrier in contact with the ground. Together with the protective structure composed of the connecting plate 3 and the hinge 2, it prevents grass clippings from flying when the blade is cutting. The mounting component 10 is fixed and has a sliding adjustment function through bolts 1005, which enables the grass trimmer head to be quickly installed and its position calibrated on different devices.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
