Description

Cleaning unit of lawn mower

This creation is about a cutting blade structure used in a lawn mower that is easy to disassemble and assemble, and is not easy to damage and wear.

At present, the commonly used lawn mower blade structure, for example, the new type M597037 "Mowing device that can prevent entanglement and jamming" announced on June 21, 109 of the Republic of China, which discloses: contains a plate Body and plural convex parts. The disc body has an upper surface, a lower surface, a connecting hole, a plurality of tool holes and a plurality of openings, wherein the connecting hole is located at the center of the disc body, and the connecting hole connects the upper surface and the lower surface of the disc body , And used to connect the disc body to a driving member of a mowing device, the plurality of cutter holes are located on the lower surface of the disc body, the plurality of openings are located on the periphery of the disc body, and the plurality of cutter holes are connected to the The plurality of openings communicate with each other. The plurality of protrusions are arranged on the upper surface and/or the lower surface of the disc body, and along with the horizontal rotation of the lawn mower, form an anti-blocking wall for protecting the gap between the lawn mower and the transmission member Gap. The mowing implement includes at least one mowing tool, and the at least one mowing tool (for example, a knife string made of plastic nylon) is installed in the plurality of tool holes.

There is also a new-type "grass-mowing rope" patent case No. M556999 announced on March 21, 107, which discloses: a rope body and a zigzag structure. The rope body is made of plastic or rubber and has multiple sides. There is a boundary line at the junction of two adjacent sides, and each boundary line is arranged along the longitudinal direction of the rope body; the zigzag structure is arranged spirally along the longitudinal direction of the rope body, wherein the zigzag structure has a plurality of recesses, and the adjacent two recesses are formed by One end point is connected, and each end point is set on each boundary line, so that when the mowing disc drives the rope body to rotate, the sawtooth structure can increase the strength of mowing, and quickly knock down the grass to improve the efficiency of mowing.

Since the mowing knives in the previous patents mentioned above are made of plastic nylon, plastic, rubber or beef tendon rope, their strength is insufficient, they are easy to wear or break when they come into contact with hard objects, and it is troublesome to assemble and disassemble. , So it is not ideal in use.

This creation is to solve the above-mentioned shortcomings in the cutter structure of the conventional lawn mower. Therefore, this creation provides a cleaning unit for a lawn mower, which is provided with a cleaning member and is provided with a plurality of winding elements, the winding elements are wound by a plurality of strands of silk, and the end of the winding element is formed with a cleaning part An upper base, which is connected to the upper part of the clearing piece; a lower base, which is connected to the lower part of the clearing piece; a fixing piece which fixes the upper base, the clearing piece and the lower base, The fixing part is provided with a screw connection end, and the screw connection end is provided with a screw hole.

The above-mentioned winding element is combined with the periphery of the cleaning member.

The above-mentioned winding element is formed by winding the filaments to form a twisted roll.

The above-mentioned removal part is arranged in a radial shape.

The upper base is set in a conical disc shape.

The lower base is set in a conical disk shape.

The screwing direction of the screw hole and a screw rod of a power source of a lawn mower is the same as the rotation direction of the screw rod.

The cleaning member is provided with a fixing hole, the upper base is provided with an upper through hole at a position corresponding to the fixing hole, the lower base is provided with a lower through hole at a position corresponding to the fixing hole, and the fixing member is provided with a rivet After the riveted end passes through the upper through hole, the fixing hole and the lower through hole in sequence, the riveted end is stamped and deformed to make the upper base, the clearing piece and the lower base secure Become one.

The fixing member is provided with two opposite ends, one of which is provided with the screw end, and the other end is provided with the riveting end.

The threaded end protrudes out of the upper through hole.

The above technical features have the following advantages:

1. It can be mainly used on lawn mowers currently on the market. The removal parts can be easily and easily locked to the screw rod of the power source of the lawn mower. You can quickly complete the assembly and use without finding tools to fix it. , Disassembly is quite simple and labor-saving.

2. The whole structure of the winding element made of silk thread can achieve light weight, and it can have a certain amount of elastic expansion and contraction when encountering hard objects, which can avoid damage, especially it is not easy to wear, and can extend its service life.

3. The winding element made of silk thread can replace the traditional plastic nylon or beef tendon rope to make the mowing knife. It has better strength, relatively better mowing effect, and a wider range of use.

4. With the structure of the removal part, in addition to mowing, it is especially suitable for corners, L-shaped corners, large-area cavities, gaps, landscapes, gardening, pedestrian walks, driveways, and corners of safety islands. In addition to the original mowing function, clearing also has the effect of sweeping.

5. Since the screwing direction of the screw rod and the screw hole is the same as the rotation direction of the power source of the lawn mower, it can be tightened even more during rotating use without being easily loosened and separated.

Please refer to the first and second figures, the present creative embodiment includes: a cleaning member 1, an upper base 2, a lower base 3, and a fixing member 4. Among them:

The cleaning element 1, the peripheral edge of the cleaning element 1 is combined with a plurality of winding elements 11, each of the winding elements 11 is wound by a plurality of strands of silk into a twisted roll shape, and the end of each winding element 11 is A radial cleaning part 12 is formed. A fixing hole 13 is provided at the center of the cleaning member 1.

The upper base 2 is connected to the upper part of the cleaning member 1. The upper base 2 is set in a conical disk shape. The upper base 2 is provided with an upper through hole 21 at a position corresponding to the fixing hole 13.

The lower base 3 is connected to the lower part of the cleaning member 1. The lower base 3 is set in a conical disk shape. The lower base 3 is provided with a lower through hole 31 at a position corresponding to the fixing hole 13.

The fixing member 4 is provided with two opposite ends. One end is provided with a threaded end 41, and the threaded end 41 is provided with a threaded hole 42. The other end of the fixing member 4 is provided with a riveting end 43 which passes through the upper through hole 21 of the upper base 2, the fixing hole 13 of the cleaning member 1, and the lower base 3 in sequence. After the lower through hole 31 (as shown in the third figure), the riveted end is stamped and deformed so that it cannot be separated from the upper through hole 21, the fixing hole 13, and the lower through hole 31, so that the The upper base 2, the cleaning member 1 and the lower base 3 are consolidated into one body. In addition, the screw end 41 of the fixing member 4 can protrude out of the upper through hole 21 of the upper base 2.

When in use, as shown in the first and fourth figures, a screw rod A1 of the power source A of the lawn mower is screwed into the screw hole 42 of the screw end 41 of the fixing member 4 to make The cleaning member 1 can be driven to rotate by the power source A of the lawn mower, so that the ends of the winding elements 11 of the cleaning member 1 can be used to form the radial cleaning portion 12, which penetrates when the cleaning member 1 rotates. The cleaning parts 12 can cut grass easily. At the same time, the cleaning part 12 of the winding element 11 made of silk thread can have a sweeping function when rotating, and the cleaning part 12 can also be used to scrape the moss and dirt attached to the corners of the ground or the wall. In addition, since the screwing direction of the screw rod A1 and the screw hole 42 of the power source A of the lawn mower is the same as the rotation direction of the screw rod A1, it can be tightened even more during rotating use. Easy to loosen and separate.
