Description

Technical Field

[0001] This utility model relates to the field of lawn mowing technology, and in particular to a novel lawn mower. Background Technology

[0002] With the rapid rise of the lawn and landscaping industry, my country has begun to focus on upgrading and using various types of lawnmowers. Most existing lawnmowers are backpack mowers, requiring operators to carry them while simultaneously mowing the lawn and vegetation. This not only increases the workload for operators but also hinders their ability to operate the mower effectively.

[0003] The existing technology uses a semi-suspended reciprocating lawnmower, which is used in conjunction with a tractor. However, after the lawn is cut, manual collection is still required, which is labor-intensive and inefficient. To address these issues, the above structure has been automated, but the structure is complex and inconvenient for subsequent maintenance and repair. In addition, because the lawnmower's center of gravity is either too far back or too far in the center, it is prone to tipping over. Utility Model Content

[0004] The problem solved by this utility model is to provide a new type of lawnmower with a simple structure and easy operation, which can collect the mower after mowing and prevent the lawnmower from tipping over by adjusting the center of gravity of the lawnmower.

The front end of the longitudinal positioning bar is provided with a chain seat 26, and both ends of the suspension zipper 22 are respectively connected to the chain seat 26. One side of the mounting plate 23 is provided with a chain sleeve 27 for passing through the suspension zipper 22. The suspension zipper 22 can increase the weight of the front of the housing 1, that is, shift the center of gravity forward, and at the same time increase the stability of the three-point suspension bracket. The housing 1 has an annular plate surrounding it. The upper part of the housing 1 has staggered longitudinal and transverse positioning strips. The gearbox cutter head assembly 31 is located at the intersection of the longitudinal and transverse positioning strips. The rear ends of the longitudinal and transverse positioning strips are provided with chain seats 26. The chain seats 26 are provided with hanging zippers 22. The other end of the hanging zippers 22 is provided with chain sleeves 27. A protective sleeve is fitted on the hanging zippers 22.

The front baffle 43 assembly includes a front baffle welded component 41, with a front baffle chain 42 at its lower part. The length of the front baffle chain 42 is greater than the distance from the lower part of the front baffle welded component 41 to the ground. The front baffle 43 is vertically positioned at the front of the housing 1, and a rear baffle 44 is vertically positioned at the rear of the front baffle welded component 41. The front baffle 43 and the rear baffle 44 are welded together. The front baffle 43 assembly can move the grass clippings and other debris from the front of the lawnmower, reducing the working pressure on the gearbox cutter head assembly 31.

[0031] The rear of the housing 1 is provided with a support assembly, which includes a rear tail wheel support rod 51 rotatably mounted on the upper part of the housing 1. A support seat 52 is rotatably mounted on the front end of the rear tail wheel support rod 51. The support seat 52 can be mounted on the housing 1 or the gearbox cutter assembly 31.

The rear baffle assembly 44 can collect cut weeds, enabling post-cutting collection.

[0033] In use, the operator connects the power unit to the power connector and the gearbox cutter assembly 31 respectively. By adjusting the angle between the rear tail wheel support rod 51 and the housing 1, the height of the lawnmower can be adjusted. The adjustment hole can fix the position of the rear tail wheel support rod 51. Since the gearbox cutter assembly 31, the three-point suspension bracket, and the suspension chain 22 are close to the front end of the housing 1, the center of gravity of the lawnmower is located slightly forward in the front-rear direction and slightly forward in the left-right direction of the housing 1, which can effectively prevent the lawnmower from tipping over. When the lawnmower is running, the front baffle 43 assembly can move the grass clippings at the front of the lawnmower, reducing the working pressure of the gearbox cutter assembly 31, while the rear baffle 44 assembly can collect the cut grass, realizing the collection after cutting. For subsequent maintenance and repair of the front baffle 43 assembly and the rear baffle 44 assembly, it is only necessary to replace the chain or remove the debris on the chain to continue operation. The structure is simple and easy to maintain and repair.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
