[0045] A lawn mower is a mechanical tool used to mow lawns, vegetation, etc. Traditional lawn mowers are mainly divided into two types: backpack type and push-type. Push-type lawn mowers are generally equipped with a corresponding walking mechanism. The operator can drive the entire lawn mower to move by hand-pushing, and cut the weeds with the rotating blade at the bottom of the lawn mower. However, there is a common problem in the use of such lawn mowers with a self-propelled mechanism, that is, during the movement, the main shaft connected to the roller is easily entangled by weeds, which in turn has a bad impact on the movement of the entire lawn mower.

[0046] In order to solve the above problems, the utility model proposes an anti-entanglement intelligent lawn mower. Figures 1 to 5 The present invention is a schematic structural diagram of an embodiment of the anti-entanglement intelligent lawn mower provided by the present invention.

[0047] Please refer to Figures 1 to 5The utility model proposes an anti-entanglement intelligent lawn mower, which mainly includes a frame 1, a walking mechanism, a cutting mechanism and an adjusting member. In order to prevent the main shaft in the driving structure of the traditional lawn mower from being easily entangled by weeds during walking, thereby affecting the operation of the entire equipment, in this embodiment, a protective sleeve 23 is provided on the outer side of the driving shaft 7 in the walking mechanism, one end of the protective sleeve 23 is fixedly installed on the driving device, and it is sleeved on the outer side of the entire driving shaft 7. In the process of the driving shaft 7 driving the driving wheel 25 to rotate, the protective sleeve 23 can isolate the external weeds from contacting the driving shaft 7, thereby avoiding the problem of weeds entangled on the driving shaft 7 during mowing, thereby affecting the rotation of the driving shaft 7, and at the same time, the mowing operation is performed. When the ground is uneven, the driving member in the shell 10 drives the cutter member outside the shell 10 to rotate and cut the weeds. In this process, the vertical height of the cutter member can be adjusted by the adjusting member according to the actual environmental conditions. Specifically, when the ground is relatively flat, the adjusting member can drive the cutter member downward so that the cutter member can cut the roots of the weeds as much as possible. When the ground is uneven, the adjusting member can drive the cutter member upward so that the downward end of the cutter member can have a certain safety distance from the ground, thereby preventing the cutter member from contacting the ground during the rotation, thereby causing damage to the cutter 33. At the same time, the adjusting function of the adjusting member can make the entire device more applicable, and can also achieve good mowing effects in different cutting environments.

[0048] In addition, a visual sensor element can be provided inside the shell 10 for collecting and processing images of the external environment, and a distance measuring sensing device can be provided at the bottom of the shell 10 for real-time sensing of the distance between the cutter element and the ground. The collected information can be processed and judged through a corresponding control device, so that the entire anti-entanglement intelligent lawn mower can select a suitable cutting path by itself, complete autonomous work, and can automatically adjust the distance between the cutter element and the ground, thereby realizing a truly intelligent lawn mowing operation.

[0049] Specifically, the cutter member includes a cutter seat 3 and a plurality of cutters 33. The movable portion 31 of the cutter seat 3 is movably mounted on a downward end portion of the shell 10, and the mounting portion 32 of the cutter seat 3 is located outside the second chamber 13, for mounting the plurality of cutters 33. The mounting portion 32 is provided with a plurality of mounting grooves 35. When in use, a suitable number of cutters 33 can be selected according to actual conditions and installed in the mounting grooves 35. The plurality of cutters 33 are further fixed and mounted by bolts 34, for easy maintenance and replacement.

[0050] The first motor 5 rotates and drives the hollow shaft 51 on the mounting plate 11 to rotate through the helical gear pair 52 , thereby driving the plurality of cutters 33 to move.

[0051] Specifically, when mowing, the first motor 5 drives the hollow shaft 51 to rotate, and the sliding shaft 4 in the hollow shaft 51 drives the knife seat 3 at its end to rotate together, so that the weeds are cut by the multiple cutters 33. At the same time, during the mowing process, the electromagnetic relay 44 will start and stop according to the actual situation. When the ground is undulating, the electromagnetic relay 44 works. After power is turned on, it attracts the magnet block 45 on the slide plate 41, thereby driving the sliding shaft 4 to move upward in the hollow shaft 51, thereby achieving the effect of moving the multiple cutters 33 upward. At this time, the distance between the multiple cutters 33 and the ground is increased, which can prevent the cutters 33 from being damaged when they are in contact with the sand and gravel on the ground. In addition, a plurality of guide sliding shafts 421 are provided on the adjustment mounting plate 42. During the up and down movement of the slide plate 41, the guide sliding shaft 421 cooperates with the through hole 411 on the slide plate 41 to slide, and cooperates with the force of the spring 43 to make the up and down movement of the entire sliding shaft 4 more stable.

[0052] The driving device specifically includes a housing 22 and a second motor 2 installed in the housing 22. Specifically, when the second motor 2 is working, it drives the driving shaft 7 to rotate through the transmission belt 24, thereby realizing the movement of the entire device.

[0053] In addition, two independent driven wheels 26 are installed on both sides of the frame 1. The two driven wheels 26 are rotatably installed on the outer side of the frame 1. When the whole device is working, the two driven wheels 26 can rotate together with the driving wheel 25, so that the whole device can achieve a more stable walking state.

[0054] In order to minimize the impact of weeds on the rotation of the driving wheel 25 and the driven wheel 26, in this embodiment, the driving wheel 25 and the driven wheel 26 are preferably set as closed rims, and a corresponding plurality of first heat dissipation holes 221 are opened on the outer shell 22 to dissipate heat for the second motor 2.

[0055] In order to enable the first motor 5 to dissipate heat efficiently during continuous operation, a heat sink is further provided in the housing 10. Specifically, the heat sink mainly includes a fan 18 and a ventilation structure on the housing 10. When the fan 18 is working, external air is introduced into the second chamber 13 through the ventilation hole 15, and then the gas in the second chamber 13 is introduced into the first chamber 12 through the ventilation port 111, and finally discharged through the second heat dissipation hole 14, thereby achieving efficient heat dissipation of the first motor 5. In addition, in order to prevent external dust or other impurities from being brought into the housing 10 during the above-mentioned gas circulation process, corresponding filter elements can also be provided at the second heat dissipation hole 14 and the ventilation hole 15 to filter the gas.

[0056] When in use, the operator can push the entire device to move through the handle 6. In addition, a photovoltaic panel 16 is provided on the outside of the shell 10 for converting solar energy into electrical energy and storing it in a battery 17. The electrical energy in the battery 17 can provide energy for the first motor 5, the second motor 2 and the electromagnetic relay 44, thereby improving the environmental friendliness of the entire device.

[0057] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
