Description

Technical Field

[0001] The utility model relates to the technical field of line-type lawn mowers, in particular to a lawn mower with a line body pressing function. Background Art

[0002] A lawn mower is also called a weed cutter, lawn mower, lawn trimmer, etc. A lawn mower is a mechanical tool used to mow lawns, vegetation, etc. It is composed of a cutter disc, an engine, running wheels, a walking mechanism, a blade, an armrest, and a control part.

[0003] With the development of lawn mowers, a wire lawn mower has been derived, which uses a high-speed rotating wire body to replace the original blade to cut the grass. Since the cutting medium used is a wire body, it will not have the problem of entanglement, but it also has the problem of being unable to cut harder materials, that is, the scope of use is limited.

[0004] The existing string mower has a wire winding method of inserting the wire from one side of the wire drum and then winding it around the wire drum. This winding method causes great force on the wire insertion point when the wire drum rotates, thereby damaging the wire. For this reason, we propose a through-insertion lawn mower with a wire pressing function. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a lawn mower with a line pressing function to solve the technical problems mentioned in the above background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a lawn mower with a wire pressing function, comprising a wire reel, mounting parts are provided on both sides of the wire reel, and a limit card is installed inside the mounting part, a wire inlet is opened inside the limit card to enable the wire to pass through, a support frame is installed inside the wire reel, and a pressing plate for pressing the wire is provided on the inner side of the support frame.

[0007] By adopting the above technical solution and through-type winding, the force at the wire entry point can be balanced when the wire drum rotates, thereby protecting the wire. In addition, since it passes through the middle of the wire drum, this part is exposed to the air, which can be beneficial to the heat dissipation of the wire.

[0008] The utility model is further configured such that both sides of the pressing plate extend to the interior of the supporting frame and are slidably connected to the inner wall of the supporting frame, bolts are arranged inside the supporting frame, and the bottom ends of the bolts extend to the end faces of the pressing plate and are rotatably connected to the end faces of the pressing plate through bearings.

[0009] By adopting the above technical solution, the pressing plate can be driven to move vertically.

[0010] The utility model is further configured that the inner wall of the support frame is located on the outer side of the bolt and is provided with a threaded wall adapted to the bolt.

[0011] By adopting the above technical solution, the effect of assisting the movement of the bolt is achieved.

[0012] The utility model is further configured that the bolt includes a driving portion extending to the end surface of the supporting frame, and a threaded portion is installed at the bottom end of the driving portion, and a telescopic shaft fixedly connected to the bottom end of the driving portion is fixedly connected to the top end of the threaded portion.

[0013] By adopting the above technical solution, the height of the pressing plate can be adjusted.

[0014] The utility model is further configured as follows: a power box is provided between the two groups of bolts, and a knob extending to the outside of the power box is provided inside the power box, a driving sprocket is installed inside the power box at the bottom end of the knob, and driven sprockets are provided on both sides of the driving sprocket, the driven sprocket is sleeved on the outside of the driving part, and the driven sprocket and the driving sprocket are connected by a chain transmission.

[0015] By adopting the above technical solution, a driving effect on the bolt is achieved.

[0016] In summary, the utility model mainly has the following beneficial effects:

[0017] 1. The utility model sets a pressing plate. First, the wire body is inserted into the wire drum from the wire inlet, so that the wire body passes through the middle of the wire drum, and then the wire body can be wound in the wire drum. After the wire body is wound, the pressing plate can press the wire body, thereby preventing the wire body from being twisted and improving the stability of the wire body winding. In addition, when the wire drum rotates, the force at the wire body insertion point can be balanced, thereby playing a protective effect on the wire body. Furthermore, the wire body passes through the middle of the wire drum, and the part exposed to the air is conducive to the heat dissipation of the wire body;

[0018] 2. The utility model sets a power box, and the pressing plate in the present application can be adaptively adjusted for wires of different specifications. Specifically, by turning the knob, the knob will drive the driving sprocket to rotate, and the driving sprocket will then drive the driven sprocket to rotate through the chain. After the driven sprocket rotates, it will drive the bolt driving part to rotate, so that the bolt rotates. After the bolt rotates, it will move under the action of the threaded wall, thereby realizing the height adjustment of the pressing plate to meet the pressing requirements of wires of different specifications.
