[0003] At present, some lawn mowers on the market still use some more traditional lawn mowers. Such lawn mowers are usually operated by sanitation workers. The sanitation workers move the operating lever to make the lawn mower cutting blade contact the weeds to achieve the weeding function. Such lawn mowers are time-consuming and laborious for workers to work for a long time. At the same time, the grass after weeding and trimming by manually controlled lawn mowers is uneven and affects the appearance. In addition, the lawn mower is not equipped with a facility to pressurize the weeds, which will cause the weeds to fly randomly due to the twisting force when cutting. Therefore, a lawn mower is proposed to solve the above problems. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model proposes a weeder, which has the advantages of stable pushing and relatively uniform weeding.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0020] like Figure 1-3As shown, a weeder proposed by the utility model comprises a machine body 1, a push-pull rod 2 is connected to the left side of the machine body 1, a handle 3 is installed on the top of the push-pull rod 2, two side wing wheels 7 are installed on both sides of the machine body 1 through wheel axles, a front baffle 8 is fixedly installed on the right side of the machine body 1, a grass pressing roller 9 is installed at the bottom of the front baffle 8, and the grass pressing roller 9 is a round roller with wide ends and narrow in the middle, an angle bracket 4 is sleeved on the outer surface of the push-pull rod 2, a stabilizing wheel 5 is installed at the bottom of the angle bracket 4, the two side wing wheels 7 and the stabilizing wheel 5 are triangularly distributed and the bottoms are located on the same horizontal plane, and a cutting structure 6 for weeding is arranged inside the machine body 1;

[0021] A control switch 10 is arranged on the top of the machine body 1 , a mounting plate 11 is fixedly arranged inside the machine body 1 , and an arch frame 12 is fixedly arranged on the top of the mounting plate 11 .

[0022] It should be noted that the push-pull rod 2 is connected to the top of the body 1 through threads, and the push-pull rod 2 can be disassembled for easy transportation. The bottom of the body 1 can be closed to prevent weeds from flying into the interior of the body 1 when the cutting structure 6 is cutting.

[0023] Specifically, when the lawn mower needs to be used to cut the weeds on the ground, the push-pull rod 2 can be connected to the body 1 first, and then the handle 3 can be fixed to the top of the push-pull rod 2. During installation, the angle frame 4 needs to be fixed to the push-pull rod 2 first, and then the stabilizing wheel 5 is fixed to the bottom of the angle frame 4, so that the stabilizing wheel 5 and the side wheels 7 on both sides of the body 1 form a triangle shape, thereby achieving the effect of stable forward movement of the lawn mower. At the same time, the cutting structure 6 needs to be opened to cut the weeds. Finally, the handle 3 needs to be pushed to make the body 1 move forward under the effect of reasoning. When the body 1 moves forward, the grass pressing roller 9 at the bottom of the front baffle 8 will press and bend the weeds, thereby providing partial pressure, so that the weeds after pressing will not fly around when being cut by the cutting structure 6. Subsequently, it is only necessary to push the body 1 forward according to the required cutting position to complete the weeding effect.

[0024] In an optional embodiment, the cutting structure 6 includes a drive motor chassis 602, a worm 603, a worm wheel 604, a transmission rod 607 and a connecting rod 608. The drive motor chassis 602 is arranged at the top of the machine body 1, one end of the worm 603 is connected to the motor output shaft in the drive motor chassis 602, one end of the worm 603 is movably connected to the top of the arch frame 12 through a bearing, and two fixed piles 609 are fixedly installed on the top of the arch frame 12. The two ends of the transmission rod 607 cross between the two fixed piles 609, and the worm wheel 604 is sleeved on the transmission rod 607. In the middle of the outer surface, the worm wheel 604 is meshed with the worm 603, and active bevel teeth 605 are fixedly installed at both ends of the transmission rod 607. There are two connecting rods 608, and the two connecting rods 608 successively penetrate the arch frame 12 and the mounting plate 11 and extend to the bottom thereof. Driven bevel teeth 606 are fixedly installed on the tops of the two connecting rods 608, and the two active bevel teeth 605 are meshed with the two driven bevel teeth 606. The bottoms of the two connecting rods 608 are fixedly installed with mowing blades 601, and the height of the grass pressing roller 9 above the ground is greater than the height of the mowing blades 601 above the ground.

[0025] Specifically, when the cutting structure 6 is needed to cut weeds, the motor inside the drive motor chassis 602 can be turned on by controlling the switch 10, so that the motor inside the drive motor chassis 602 drives the worm 603 to rotate, and because the worm 603 is meshed with the worm wheel 604, the worm wheel 604 drives the transmission rod 607 to rotate, and the rotation of the transmission rod 607 also drives the active bevel teeth 605 at both ends to rotate, so that the two active bevel teeth 605 drive the two driven bevel teeth 606 to rotate, and at the same time, the driven bevel teeth 606 are fixed on the top of the connecting rod 608, so that the connecting rod 608 drives the mowing blade 601 to rotate together to achieve the effect of mowing.

[0026] In an optional embodiment, a control unit is disposed inside the body 1 , and the control unit is electrically connected to the control switch 10 and the drive motor chassis 602 , respectively, and the control unit is used to transmit signals and control instructions to the control switch 10 and the drive motor chassis 602 .
