[0002] Landscaping refers to the practice of planting trees, flowers, lawns and other vegetation in cities, villages, industrial and mining enterprises, traffic arteries and other areas to improve the environment, beautify the landscape and enhance people's quality of life. A lawn mower is a mechanical tool used to trim lawns, vegetation, weeds, etc.

[0003] The lawn mowers currently used in landscaping are mainly composed of a frame, a motor and a blade. By moving the frame, the position of the motor and the blade can be changed, thereby driving the blade to rotate and trimming the lawn, vegetation and weeds. However, the current lawn mowers have the following shortcomings in actual operations: when the work site contains stones, the blade disc accidentally contacts the stone, which will not only damage the blade disc, but may also cause harm to surrounding personnel. In addition, when encountering a row of flowers and plants, the lawn mower can only trim the lawn and weeds on one side at a time, and then the other side needs to be trimmed again, which leads to low work efficiency and high labor intensity, and also limits the applicability of the lawn mower.

[0004] Therefore a kind of gardening weeder is proposed to solve the above problems. Utility Model Content

The horizontal plate 1 is provided with a positioning member for the L-shaped plate 21. The positioning mechanism 3 is a positioning mechanism, and a winding plate 4 is horizontally arranged on the inner side of the two L-shaped plates 21, and a rotating shaft 5 is rotatably connected between one end of the winding plate 4 close to the vertical end of the L-shaped plate 21 on the same side and the horizontal end of the L-shaped plate 21 on the same side, and a pulling mechanism 6 for driving the winding plate 4 to rotate around the rotating shaft 5 is arranged on the telescopic plate 23, and round rods 7 are equidistantly arranged at the bottom of the winding plate 4 in the horizontal direction, and motors 81 located in front of the winding plate 4 are arranged at the bottom of the horizontal ends of the two L-shaped plates 21, and blades 82 are arranged on the output shafts of the two motors 81.

[0025] In this embodiment, the motor 81 drives the blade 82 to rotate to trim the lawn, vegetation and weeds. The pulling mechanism 6 drives the winding plate 4 to rotate around the rotating shaft 5, and repeats this process. The round rod 7 thereon moves accordingly, so that the round rod 7 pushes the stone to both sides to avoid contact with the running blade 82, thereby avoiding damage to the blade or injury to the surrounding personnel. When trimming the lawn and weeds on both sides of a row of flowers and plants, the two L-shaped plates 21 are pulled to both sides along the two ends of the telescopic plate 23 until the distance between the two blades 82 is greater than the width of a row of flowers and plants, and the positions of the two L-shaped plates 21 are fixed by the positioning mechanism 3. At this time, the mobile device can trim the lawn and weeds on both sides at the same time, thereby improving work efficiency, reducing labor intensity, and improving the applicability of the equipment.

[0026] Preferably, as another embodiment of the utility model, the positioning mechanism 3 includes a hand bolt 31 and a positioning groove 32, and the tops of the horizontal ends of the two L-shaped plates 21 are each laterally and evenly provided with a plurality of positioning grooves 32, and hand bolts 31 are provided at both ends of the top of the horizontal plate 1, and the lower ends of the two hand bolts 31 extend to the interior of the positioning grooves 32 on both sides.

[0027] In this embodiment, when the hand bolt 31 is screwed out of the positioning groove 32 on the horizontal end of the L-shaped plate 21, the L-shaped plate 21 can be pulled along the telescopic plate 23, and when the hand bolt 31 is screwed into the positioning groove 32 on the horizontal end of the L-shaped plate 21, the L-shaped plate 21 can be positioned to adjust the distance between the two L-shaped plates 21.

[0028] Preferably, as another embodiment of the utility model, the pulling mechanism 6 includes a pulling rod 61, a circular frame 62 and an electric push rod 63. The bottom of the telescopic plate 23 is provided with an electric push rod 63 along the front and rear directions. The telescopic end of the electric push rod 63 faces rearward and is provided with a circular frame 62 in the shape of a Chinese character "U". The two winding plates 4 are provided with a pulling rod 61 extending to pass through the inside of the circular frame 62 at one end close to the vertical end of the L-shaped plate 21 on the same side. The front and rear inner walls of the circular frame 62 are provided with strip grooves 111 in the horizontal direction, and the front and rear sides of the pulling rod 61 are provided with rollers 112 extending to the inside of the strip groove 111 on the same side.

[0029] In this embodiment, when the telescopic shaft of the electric push rod 63 is continuously extended and retracted, the circular frame 62 can be driven to reciprocate along the front and rear directions. In this process, the winding plate 4 can be driven to rotate back and forth around the center of the rotating shaft 5 through the pulling rod 61, and the round rod 7 on the winding plate 4 moves accordingly, thereby pushing the stone to both sides to avoid contact with the running blade 82.

[0032] In this embodiment, when one of the round rods 7 is damaged, the round rod 7 can be rotated and screwed out from the internal thread groove to replace a new round rod 7, thereby providing the function of replacing a new round rod 7.

[0033] Working principle: Place the device on the ground, the caster 9 is in contact with the ground, hold the push handle 10 to push the device to move, and drive the blade 82 to rotate through the motor 81, so as to trim the lawn, vegetation and weeds, and drive the electric push rod 63 to continuously extend and retract, thereby driving the circular frame 62 to reciprocate along the front and rear directions. In this process, the pull rod 61 can drive the winding plate 4 to rotate back and forth around the center of the rotating shaft 5, and the round rod 7 on the winding plate 4 moves accordingly, thereby pushing the stone to both sides to avoid contact with the running blade 82, thereby damaging the blade or injuring the surrounding personnel. When trimming the lawn and weeds on both sides of a row of flowers and plants, pull the two L-shaped plates 21 to both sides along the two ends of the telescopic plate 23 until the distance between the two blades 82 is greater than the width of a row of flowers and plants, then screw the hand bolt 31 into the positioning groove 32 on the horizontal end of the L-shaped plate 21, and then position the two L-shaped plates 21 so that the distance between the two blades 82 is fixed. At this time, the mobile device can trim the lawn and weeds on both sides at the same time.
