Description

Technical Field

[0001] This utility model relates to a front wheel axle structure for a lawnmower, belonging to the field of front wheel axle technology. Background Technology

[0002] A lawnmower, also known as a lawn mower, lawn trimmer, or lawn mower, is a mechanical tool used for trimming lawns and vegetation. It consists of a cutter head, engine, wheels, a drive mechanism, blades, a handle, and a control unit. The cutter head is mounted on the wheels, and the engine is mounted on the cutter head. The blades are mounted on the engine's output shaft. The high-speed rotation of the blades, powered by the engine, significantly increases the speed of lawn mowing, saving workers' time and reducing manpower.

[0003] For example, patent number CN202111044772.1 discloses an electric drive cutting height adjustment device for a lawnmower and a lawnmower, including: a front wheel axle for mounting two front wheels; and a rear wheel axle for mounting two rear wheels. In this solution, when the front wheels are installed, there is a gap between the front wheels and the wheel axle mounting seat, which can easily cause weeds to get tangled in. However, there is no corresponding cleaning device. After weeds get tangled, the friction increases, making it difficult to cut grass. Therefore, we have designed a front wheel axle structure for a lawnmower. Utility Model Content

[0004] The purpose of this invention is to provide a front wheel axle structure for a lawnmower to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a front axle structure for a lawnmower, comprising an axle portion and two body mounting plates. The two ends of the axle portion are welded to the two body mounting plates respectively. Blade concealment frames are installed on the sides of the two body mounting plates. Lawn mowing blades are installed inside the two blade concealment frames. A sliding adjustment groove is provided on one side of each of the two blade concealment frames. An adjustment handle is installed inside each of the two sliding adjustment grooves. Each adjustment handle is connected to the bottom of each grass mowing blade.

[0006] In the aforementioned front axle structure for a lawnmower, two symmetrical corner bracket positioning sleeves are provided on the outer surface of the axle portion, and a positioning corner bracket is installed on one side of each of the two corner bracket positioning sleeves.

[0007] In the aforementioned front axle structure for a lawnmower, both ends of the two mounting plates are provided with integrally formed bent mounting portions, and each bent mounting portion has a positioning hole on its upper side.

[0008] In the aforementioned front axle structure for a lawnmower, locating pins are installed on the sides of both of the machine body mounting plates, and a bolt connection is installed at one end of each locating pin.

[0009] In the aforementioned front wheel axle structure for a lawnmower, one end of each bolt connection is provided with a notch, and an expansion portion is installed inside each notch.

[0010] In the aforementioned front axle structure for a lawnmower, the end of each corner bracket positioning sleeve near the end of the corresponding blade concealment frame does not contact the blade concealment frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model relates to a front wheel axle structure for a lawnmower. By installing a blade concealment frame on the side of the mounting plate of the machine body, and installing lawnmower blades inside the blade concealment frame, the lawnmower blades can be driven to move upward through the connection of the adjusting handle to the lawnmower blades, so as to cut the rolled grass, achieve effective weed clearing, and facilitate continuous lawnmower operation.
