[0028] The multi-purpose lawn mower comprises a crawler walking mechanism 1, a negative pressure fan 6, a high-branch saw assembly, a camera 4, a telescopic assembly and a lawn mowing assembly.

[0029] The crawler travel mechanism 1 uses a conventional crawler travel mechanism 1 available on the market, and the crawler travel mechanism 1 includes a guide wheel, a follower wheel, a supporting wheel, a driving wheel 1 and a crawler 12. During operation, the driving wheel winds around the crawler 12 for circular motion, and the supporting wheel rolls forward or backward on the track of the crawler 12. The crawler travel mechanism 1 has the advantages of low pressure per unit area on the soil, good adhesion to the soil, and not easy to slip. It has good passing performance in wet and soft soil areas, high traction efficiency, and can also play a certain protective role on the lawn.

[0030] A collecting groove 11a is provided on the front side of the bottom of the frame 11 of the crawler traveling mechanism 1, and the collecting groove 11a extends to the front end surface of the frame 11 of the crawler traveling mechanism 1, and a screening plate 11b is fixedly installed at the opening of the collecting groove 11a. A plurality of screening grooves are sequentially provided on the bottom of the screening plate 11b along the left and right directions, and a grass storage bin 11c is provided at the rear of the frame 11 of the crawler traveling mechanism 1, and a grass storage box 11d is placed in the grass storage bin 11c.

[0031] The collecting trough 11a is connected to the grass storage bin 11c through a negative pressure channel 11e. A negative pressure chamber 11f is opened in the middle of the frame 11 of the crawler walking mechanism 1. The negative pressure chamber 11f is connected to the negative pressure channel 11e through an air outlet, and the air outlet is aligned with the negative pressure channel 11e close to the grass storage bin 11c. The negative pressure fan 6 is installed in the negative pressure chamber 11f.

[0032] The crawler walking mechanism 1 may have a lifting system, which is composed of a hydraulic lifting cylinder 13 and a swing arm 14. There are four sets of hydraulic lifting cylinders 13 and swing arms 14 respectively. The crawler is hinged to the frame 11 through the swing arm 14, the piston rod end of the hydraulic lifting cylinder 13 is hinged to the swing arm 14, the cylinder body of the hydraulic lifting cylinder 13 is hinged to the frame 11, and the swing arm 14 is hinged to the skeleton of the crawler 12. When mowing is required, the hydraulic lifting cylinder 13 is extended, so that the swing arm 14 moves downward with the arm length as the radius, thereby driving the crawler 12 to move downward. The length of the extension of the hydraulic lifting cylinder 13 can be adjusted to adjust the mowing height.

[0033] The mowing assembly includes a mowing motor 21, a rotating wheel 22 and five blades 23. The mowing motor 21 is installed in the frame 11 of the crawler walking mechanism 1 by bolts, and the rotating wheel 22 is installed on the output shaft of the mowing motor 21. The rotating wheel 22 is in the collecting groove 11a, and the five blades 23 are evenly distributed along the axial direction of the rotating wheel 22.

[0034] The rotating wheel 22 is at the bottom of the frame 11 of the crawler walking mechanism 1, and the rotating wheel 22 is connected to the mowing motor 21. When mowing, the mowing motor 21 is turned on, and the rotating wheel 22 starts to rotate to drive the blade 23 to mow. A negative pressure channel 11e is provided behind the rotating wheel 22, and the grass fluff is sucked into the grass storage box 11d behind the frame 11 of the crawler walking mechanism 1 through high-speed rotation for storage.

[0035] The high branch saw assembly includes a high branch saw head 31 and a mechanical arm 32. The mechanical arm 32 is a six-axis mechanical arm 32 with a folding design. The high branch saw head 31 is installed at the far end of the mechanical arm 32, and the proximal end of the mechanical arm 32 is installed on the crawler walking mechanism 1.

[0036] The frame 11 of the crawler traveling mechanism 1 is provided with an equipment storage slot 11g for accommodating the high-branch saw assembly.

[0037] The camera 4 is arranged on the frame 11 of the crawler walking mechanism 1 through a telescopic assembly. The telescopic assembly includes a telescopic sleeve 51, a telescopic inner tube 52 and an electric cylinder 53. The lower end of the telescopic sleeve 51 is welded and fixed to the frame 11 of the crawler walking mechanism 1, the telescopic inner tube 52 is sleeved in the telescopic sleeve 51, the cylinder body of the electric cylinder 53 is fixed inside the telescopic sleeve 51, the piston rod of the electric cylinder 53 is fixed to the telescopic inner tube 52, and the camera 4 is fixedly installed on the upper end of the telescopic inner tube 52.

[0038] The camera 4 can detect the environment on the route of the multi-purpose lawn mower, which is convenient for planning the weeding route and can avoid obstacles.

[0039] When the green belt is not being pruned, the mechanical arm 32 and the high-branch saw assembly are in a folded state, folded into the equipment storage slot 11g of the frame 11 of the crawler walking mechanism 1. Before the pruning operation is performed, the mechanical arm 32 is extended from the folded state to the unfolded state, and the high-branch saw head 31 at the front end of the mechanical arm 32 is also driven by a motor to cooperate with the mechanical arm 32 to prune the green belt.

[0040] In this embodiment, the crawler walking mechanism 1, the high-branch saw head 31 and the mechanical arm 32 and other components are all existing products or mature technologies.

[0041] In addition, the multi-purpose lawn mower can also cooperate with existing remote control equipment, and a control circuit is installed on the multi-purpose lawn mower. The control circuit has a receiving module and a sending module. The control circuit can output the real-time image signal captured by the camera 4 to the remote control device, and the control circuit uses the receiving module to receive the control signal sent by the remote control device to realize remote control of the multi-purpose lawn mower. The multi-purpose lawn mower can also cooperate with the existing unmanned control system to realize the automatic mowing operation of the multi-purpose lawn mower.

[0042] The above is only one embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the principle of the present invention, and these should also be regarded as belonging to the protection scope of the present invention.
