Description

Technical Field

[0001] This utility model relates to the field of lawn trimmer technology, specifically a lawn trimmer with a protective device. Background Technology

[0002] The basic principle of a lawn mower is to trim excess grass blades from the edges of the lawn by rotating blades. Different types of lawn mowers may require different types of blades, and the appropriate type must be selected based on the machine model and blade specifications. Furthermore, the cutting depth can be adjusted according to the needs of the lawn to avoid cutting too deep or too shallow. Most lawn mowers now have protective covers on the outside of the blades; however, these covers only protect the blades. During mowing, the blades may come into contact with stones, and existing protective devices cannot remove these stones, allowing the blades to easily come into contact with them and cause damage. Therefore, we propose a lawn mower with an integrated protective device. Utility Model Content

[0003] The purpose of this invention is to provide a lawn trimmer with a protective device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lawn mower with a protective device, comprising a housing, a mowing blade rotatably connected to the bottom of the housing, a handle on the outer wall of the housing, a brushed motor on the handle, a switch handle on the brushed motor, a grip fixedly mounted on the handle, a protective component on the outer wall of the housing, a grass-blocking plate on the outer wall of the handle, two sets of moving wheels below the handle, and an adjustment mechanism on the outer wall of the grass-blocking plate.

[0005] Furthermore, the protective assembly includes three sets of fixing rods on the outer wall of the housing, and a first protective plate on the outer wall of the three sets of fixing rods.

[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] Example 1:

[0019] Please see Figure 1-2 This utility model provides a technical solution: a lawn mower with a protective device, including a housing 1, a mowing blade 2 rotatably connected to the bottom of the housing 1, a handle 7 on the outer wall of the housing 1, a brushed motor 9 on the handle 7, a switch handle 10 on the brushed motor 9, a grip 8 fixedly mounted on the handle 7, a protective component 3 on the outer wall of the housing 1, a grass baffle 4 on the outer wall of the handle 7, two sets of moving wheels 6 below the handle 7, and an adjustment mechanism 5 on the outer wall of the grass baffle 4.

[0020] Please see Figure 1-2 The protective component 3 includes three sets of fixing rods 30 on the outer wall of the housing 1. A first protective plate 31 is provided on the outer wall of the three sets of fixing rods 30. A cavity 34 is opened inside the first protective plate 31. A lifting plate 36 is slidably connected in the cavity 34. Two sets of sliding rods 37 are movably connected through the top of the lifting plate 36. The two ends of the two sets of sliding rods 37 are respectively connected to the upper and lower side walls of the cavity 34. Under the action of the sliding rods 37, the lifting plate 36 moves up and down more stably. An electric telescopic rod 35 is provided at the top of the cavity 34. One end of the electric telescopic rod 35 is connected to the top of the lifting plate 36. A second protective plate 32 is movably connected through the bottom of the first protective plate 31. The top of the second protective plate 32 is connected to the bottom of the lifting plate 36. Both the first protective plate 31 and the second protective plate 32 are arc-shaped. A pusher plate 33 is provided on the outer wall of the second protective plate 32.

[0021] Please see Figure 3The adjustment mechanism 5 includes a fixed box 50 on the outer wall of the grass baffle 4. A sliding plate 55 is slidably connected inside the fixed box 50. Guide grooves are provided on both the left and right side walls of the fixed box 50. Guide blocks matching the guide grooves are provided on both the left and right side walls of the sliding plate 55. Under the action of the guide grooves and guide blocks, the two sets of sliders 51 move more stably on the outer wall of the bidirectional screw 52. Two sets of lifting rods 56 are provided at the bottom of the sliding plate 55. One end of each set of lifting rods 56 passes through the bottom of the fixed box 50 and is connected to the moving wheel 6. A bidirectional screw 52 is connected to the left side wall of the fixed box 50 through a bearing. One end of the bidirectional screw 52 passes through the right side wall of the fixed box 50 and is connected to the rotating plate 54 on the outside. Sliders 51 are sleeved on both the left and right sides of the outer wall of the bidirectional screw 52. Connecting rods 53 are hinged at the bottom of each set of sliders 51. One end of each set of connecting rods 53 is hinged to the top of the sliding plate 55.

[0022] Working principle: The operator holds the handle 8 and turns on the switch handle 10. The brushed motor 9 drives the lawn mower blade 2 to rotate, which mows the lawn. The lawn mower blade 2 can cut and trim the lawn. The grass barrier 4 can block the cut grass. The operator rotates the rotating plate 54, which drives the double-acting screw 52 to rotate. Under the action of the guide groove and guide block, the two sets of sliders 51 move relative to each other on the outer wall of the double-acting screw 52. The sliders 51 drive the connecting rod 53 to rotate, and the connecting rod 53 drives the sliding plate 55 to move downward. The sliding plate 55 drives the lifting rod 56 and the moving wheel 6 to move downward, so that the moving wheel 6 contacts the lawn. The electric telescopic rod 35 drives the lifting plate 36 to move downward. The lifting plate 36 drives the second protective plate 32 and the push stone plate 33 to move downward. The first protective plate 31 and the second protective plate 32 can protect the blade. When the lawn mower blade 2 moves to cut the lawn, the push stone plate 33 moves to push the stones in the lawn, preventing the lawn mower blade 2 from contacting the stones and causing damage, thus protecting the lawn mower blade 2 from damage.
