Description

Technical Field

[0001] This utility model relates to the field of garden brush cutter technology, specifically a brush cutter with a double protection structure. Background Technology

[0002] As people's living standards gradually improve, they are paying more and more attention to the greening of their living environment. There are more and more green spaces such as flower beds, courtyards and gardens, which can be seen everywhere in life. In order to effectively maintain the greening in the garden, people need to use brush cutters regularly to prune the garden greening. During the brush cutting process, the brush cutter is usually driven by a motor to rotate the rotating disc and the rotating blades at high speed to cut the greening.

[0003] However, existing brush cutters have certain shortcomings in actual use. Although some are equipped with protective devices that can protect the cutting process and prevent the rotating blades from contacting impurities such as stones, ensuring safety during use, they cannot provide good protection when encountering impurities with relatively large particle size or mass.

[0020] 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.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a brush cutter with a double protective structure, including a base plate 1, on which a drive device body 3 (mainly including a motor, a relatively mature technology, which will not be described in detail here) of a brush cutting component is installed. The output end of the drive device body 3 passes through the base plate 1 and extends downward to be fixedly installed with a rotating blade 7. The bottom end of the base plate 1 is provided with a protective cover 8 that matches the rotating blade 7 to provide protection. The sides of the base plate 1 are equipped with walking wheels 4 of a walking component. The rear end of the base plate 1 is welded with a pusher 2, which can be used to easily push the whole unit to move, thus facilitating its use. The front end of the base plate 1 is fixedly provided with a mounting plate 5 (which can be fixed by welding or screws), and the mounting plate 5 has a groove 11 in the middle.

[0022] Please see Figures 1-4 To provide protection during use and to push away stones and other debris without interfering with pruning, the base plate 1 has rotating rods 17 on both sides. A limit plate 16 is welded to the bottom of each rotating rod 17, and a protective plate 15 is mounted on the outside of the rotating rod 17. A protective push plate 6 is welded to the end of the rotating plate 15. Figure 3As shown in the diagram, rubber gaskets 12 are glued to the side walls of the two protective push plates 6 that are close to each other. In order to facilitate the installation and subsequent disassembly of the rotating rod 17, the rotating rod 17 is also provided with threaded holes 20 for mounting components. Threaded posts 19 are engaged in the threaded holes 20 through threads. The top of the threaded posts 19 is welded with mounting bolts 18. In order to facilitate the pushing away of large-diameter or relatively heavy stones and other impurities without affecting the subsequent trimming of grass and trees, a vertical plate 9 of the drive component is welded to the base plate 1, and a connecting plate 10 is welded to the protective push plate 6. Rotating parts 13 are provided on the side walls of the connecting plate 10 and the vertical plate 9. The two rotating parts 13 are connected by an electric push rod 14. The electric push rod 14 can be extended and retracted to cooperate with the rotating parts 13 and the rotating rod 17, etc., to rotate and open the protective push plate 6, so as to easily push away stones and other impurities, and then carry out the trimming operation.

[0023] Working principle: When in use, this utility model can be moved by pushing the pusher 2 in conjunction with the walking wheels 4. At this time, the protective push plate 6 at the front end pushes away stones and other impurities on the lawn. The electric push rod 14 can also be extended, and in conjunction with the rotating part 13, the rotating rod 17 and the rotating plate 15, the protective push plate 6 can be rotated to push stones and other impurities (mainly for large-diameter impurities) to both sides without affecting the subsequent trimming operation. Then the electric push rod 14 retracts to assist, and the protective push plate 6 rotates back to its original position for easy pushing. The main body 3 of the drive device can rotate the rotating blade 7 to trim the grass and trees, and the protective cover 8 can also provide protection for the rotating blade 7.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
