Description

Technical Field

[0001] The invention relates to the technical field of lawn mowers, in particular to a lawn mower. Background Art

[0002] The lawn is an artificial lawn that is densely planted with perennial short herbaceous plants and trimmed. A mower is needed to trim the lawn. There are two main types of lawn mowers in the prior art. One is a handheld type, such as the lawn mower in CN211982643U, which has a light structure, but because the body does not touch the ground, it is difficult to ensure uniform trimming height during handheld mobile trimming; the other is a cart type, such as the lawn mower in CN218604032U, which touches the ground when pushed and can trim the lawn evenly, but the height difference between the blade and the moving wheel is fixed and cannot be adjusted, resulting in a fixed trimming height for the lawn, which is difficult to meet different trimming height requirements and has shortcomings. Summary of the invention

[0003] The object of the present invention is to provide a lawn mower to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] The present invention provides a lawn mower, comprising a mower body, a walking structure and a hand lever, wherein a mower wire is arranged at the lower part of a head at the front end of the mower body, the rear end of the mower body is fixedly connected to the hand lever, and tooth grooves are arranged on both sides of the rear part of the mower body, the walking structure comprises a fixed plate, a plurality of rollers are arranged at the bottom of the fixed plate, and two upright tooth plates are arranged at the upper part, the tooth plates are higher than the tooth grooves, and the tooth plates can be inserted into the tooth grooves backwards, the fixed plate is located at the lower part of the mower body, and the bottom surface of the roller is lower than the mower wire.

[0006] As an improvement, the trimmer body is provided with a motor and a battery, the upper part of the head of the trimmer body is provided with a switch, the lower part of the head is provided with a rotating head, the trimming wire is provided at the lower part of the rotating head, the motor controls the rotation of the rotating head, and the motor, switch and battery are electrically connected.

[0007] As an improvement, a guard plate is provided at the front end of the tooth plate, and the guard plate can be magnetically connected to the end face of the tooth groove.

[0008] As an improvement, the rollers are rotatable rollers, there are three of them, one of which is ahead.

[0009] As an improvement, the trimming wire is made of metal or plastic.

[0010] Compared with the prior art, the invention has the advantage that when uniformity of trimming is not required, the invention does not need to use a walking structure and can be used as a handheld trimmer for rough trimming.

[0011] When uniformity of trimming is required, the height difference between the bottom surface of the roller and the trimming wire is determined according to the trimming height requirements, and then the tooth plate is inserted into the tooth groove. The fence and the end surface of the tooth groove are magnetically attracted to increase the stability of the connection. The trimmer body is placed on the lawn, with the three rollers on the ground. After pressing the switch, the trimming wire rotates at high speed to perform interrupted trimming of the weeds. The trimmer body can be pushed on the lawn by holding the hand lever for trimming.

[0012] The walking mechanism of the lawn mower can be separated from the mower body, so that it can be used in a handheld manner or in a cart-type manner. The height difference between the bottom surface of the roller and the mowing wire can be adjusted to meet different mowing height requirements. The use is light and convenient, and has high practical value and promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
