Description

Technical Field

[0001] The utility model belongs to the technical field of lawn mowers, and particularly refers to an anti - entanglement structure for a lawn mower. Background Art

[0002] A lawn mower is a kind of electric tool for landscaping and lawn trimming. It is usually composed of a machine head and a handle, etc. A motor and a grass - cutting component are installed at the front end of the machine head. Generally, when the lawn mower is in use, the lawn is overgrown with dense weeds. The machine head of the lawn mower is composed of many parts. When the lawn mower is working, the cut weeds will be wound around the machine head or between the saw blade and the machine head due to the rotating wind force or other reasons. This not only affects the work efficiency, but also because some longer grass will wind around the machine head from the gap. It is very troublesome to clean after stopping work. Therefore, there is a need for a lawn mower that can prevent grass from winding around the saw blade and the machine head. Summary of the Invention

[0003] The purpose of the utility model is to provide a lawn mower with a simple structure that can prevent grass from winding around the saw blade and the machine head.

[0004] The purpose of the utility model is achieved as follows:

[0005] An anti - entanglement structure for a lawn mower includes a machine - head main body. A driving motor and a transmission shaft are arranged in the machine - head main body. The driving motor is directly or indirectly connected to the transmission shaft. A saw - blade mounting device is also arranged on the transmission shaft. A saw blade and a grass - cutting blade are arranged on the saw - blade mounting device. The saw blade is connected to the transmission shaft and can rotate synchronously with the transmission shaft. The grass - cutting blade protrudes from the saw - blade mounting device. The saw - blade mounting device can drive the grass - cutting blade to rotate synchronously with the transmission of the transmission shaft. The grass - cutting blade can cut the grass wound around the saw - blade mounting device when rotating with the transmission shaft. A blade mounting part is arranged on the saw - blade mounting device, and a threaded hole is opened in the blade mounting part. A fixing screw can be installed in the threaded hole. The fixing screw passes through the grass - cutting blade and is threadedly connected to the threaded hole and fixedly installed on the blade mounting part.

[0006] Furthermore, a bending part is also arranged on the grass - cutting blade. When the grass - cutting blade is installed on the blade mounting part through the fixing screw, the bending part is closely attached to one side of the blade mounting part.

[0007] Furthermore, the grass - cutting blade is vertically arranged on the saw - blade mounting device.

[0008] Furthermore, the saw - blade mounting device includes a clamping part and a fixing part. The saw blade is located between the clamping part and the fixing part. The grass - cutting blade is arranged on the outer wall of the clamping part through the blade mounting part, and the grass - cutting blade is located above the saw blade.

[0009] Furthermore, a number of protruding parts are also annularly arranged on the clamping part.

[0010] Furthermore, a grass-proof plate is provided at the rear end of the machine head body.

[0011] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0012] The utility model discloses an anti-grass entanglement structure of a lawn mower, comprising a head body, wherein a drive motor and a transmission shaft are arranged in the head body, the drive motor is directly or indirectly connected to the transmission shaft, a saw blade mounting device is further provided on the transmission shaft, a saw blade and a grass cutting blade are arranged on the saw blade mounting device, the saw blade is connected to the transmission shaft and can rotate synchronously with the transmission shaft, the grass cutting blade is convexly arranged on the saw blade mounting device, the saw blade mounting device is driven by the transmission shaft and can drive the grass cutting blade to rotate synchronously, and the grass cutting blade rotates with the transmission shaft to cut the grass wound on the saw blade mounting device When the lawn mowers currently on the market are working, the cut weeds will be entangled in the machine head or the gap between the saw blade and the machine head due to the rotating wind or other reasons, which not only affects the working efficiency, but also makes cleaning very troublesome after stopping work because some longer grass will go around the machine head from the gap. The utility model is provided with a mowing blade on the saw blade mounting device. When some longer weeds are caught in the gap between the saw blade and the machine head and entangled with the saw blade mounting device or even the machine head body, the mowing blade can effectively cut the grass, making it very easy for the user to clean. The mowing blade of the utility model is arranged on the saw blade mounting device, and the saw blade mounting device rotates synchronously with the saw blade. Therefore, the mowing blade also rotates synchronously with the saw blade mounting device. At this time, the lower end of the long weeds is entangled in the gap, and the upper end will be wound up step by step. Ordinary lawn mowers on the market are very troublesome to clean when encountering this situation, because the two ends of the weeds are entangled in different places, and it is easy to damage the internal parts if they are pulled hard. The grass mowing blade of the utility model can cut the weeds in half when it contacts the weeds when the saw blade mounting device rotates with the saw blade mounting device. Even if some weeds are still entangled on the saw blade mounting device, the mowing blade will still cut the entangled weeds so that they will not be entangled on the saw blade mounting device in circles. When the work stops, the weeds entangled in the gap are all cut grass. This kind of grass is basically accumulated in the gap after being cut, so it is very easy to clean. The detachable design allows the blade to be replaced when it is blunt, avoiding repeated replacement of the entire part to cause waste of resources. The installation of the utility model only requires a simple fixing screw to complete, which is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model relates to an anti - entanglement grass structure of a lawn mower, which comprises a machine head main body 1. A driving motor 2 and a transmission shaft 3 are arranged in the machine head main body 1. The driving motor 2 is directly or indirectly connected to the transmission shaft 3. A saw blade mounting device 4 is also arranged on the transmission shaft 3. A saw blade 5 and a mowing blade 6 are arranged on the saw blade mounting device 4. The saw blade 5 is connected to the transmission shaft 3 and can rotate synchronously with the transmission shaft 3. The mowing blade 6 protrudes from the saw blade mounting device 4. The saw blade mounting device 4 can drive the mowing blade 6 to rotate synchronously with the transmission of the transmission shaft 3. When the mowing blade 6 rotates with the transmission shaft 3, it can cut the grass wrapped around the saw blade mounting device 4. When the existing lawn mowers on the market are working, the cut weeds will be wrapped around the machine head or the gap between the saw blade 5 and the machine head due to the rotating wind force or other reasons, which not only affects the working efficiency. Because some longer grasses will wind around the machine head from the gap, it is very troublesome to clean after stopping work. The utility model is provided with a mowing blade 6 on the saw blade mounting device 4. When some longer weeds are involved in the gap between the saw blade 5 and the machine head and wind around the saw blade mounting device 4 or even the machine head main body 1, the mowing blade 6 can effectively cut the grass, making it very easy for the user to clean. The mowing blade 6 of the utility model is arranged on the saw blade mounting device 4, and the saw blade mounting device 4 will rotate synchronously with the saw blade 5. Therefore, the mowing blade 6 will also rotate synchronously with the saw blade mounting device 4. At this time, the lower end of the long weed is wound in the gap, and the upper end will wind upwards step by step. When the ordinary lawn mowers on the market encounter this situation, it is very troublesome to clean, because the two ends of the weed are wound around different places respectively, and it is very easy to damage the internal parts if pulled hard. When the mowing blade of the utility model rotates with the saw blade mounting device 4 and contacts the weed, it can cut the weed in half. Even if some weeds still wind around the saw blade mounting device 4, the mowing blade 6 will still cut the winding weeds so that they will not wind around the saw blade mounting device 4 in circles. When stopping work, the weeds wound in the gap are all cut weeds. Since these weeds are basically piled up in the gap after being cut, it is very easy to clean. It has a detachable design. When the blade is blunt, it can be replaced, avoiding resource waste caused by repeatedly replacing the whole part. And the installation of the utility model only needs to be completed through simple fixing screws, which is simple and convenient.

[0028] Preferably, a bending part 9 is also arranged on the mowing blade 6. When the mowing blade 6 is installed on the blade mounting part 7 through fixing screws, the bending part 9 closely adheres to one side of the blade mounting part 7, preventing the mowing blade 6 from being too long or too short during installation, which may affect mowing. The utility model only needs to set a bending on the mowing blade 6. When the mowing blade 6 is installed on the blade mounting part 7 and the mowing blade 6 is fixed by fixing screws, the bending part 9 will closely adhere to one side of the blade mounting part 7. At this time, even if the user controls the installation of the mowing blade 6 again, it cannot move.

[0029] Preferably, the mowing blade 6 is vertically provided with a saw blade mounting device 4, which can more effectively cut weeds on the saw blade mounting device 4 compared to the horizontal setting.

[0030] Preferably, the saw blade mounting device 4 includes a clamping member 10 and a fixing member 11. The saw blade 5 is located between the clamping member 10 and the fixing member 11. The mowing blade 6 is arranged on the outer wall of the clamping member 10 through a blade mounting portion 7, and the mowing blade 6 is located above the saw blade 5.

[0031] Preferably, a plurality of protruding portions 13 are further annularly arranged on the clamping member 10. Compared with the smooth design on the market, the present invention can effectively prevent grass from winding around the clamping member 10 by adding the protruding portions 13.

[0032] Preferably, a grass guard 12 is further arranged at the rear end of the machine head main body 1 to prevent the weeds cut at one time from hitting the user's body.

[0033] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
