[0030] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] As described in the background art, it is difficult for a lawn mower to adapt to the requirements of mowing grass of different slopes and terrains as well as grass of different heights.

[0032] In order to solve this technical problem, the present invention provides a self-propelled slope protection special mower, which is used for mobile mowing.

[0033] Specifically, please refer to Figure 1-Figure 7 A self-propelled slope protection special mower, comprising a frame 1 and a frame extension kit 2 installed on the frame 1, characterized in that a walking assembly 3 is arranged on the frame 1, a mowing assembly 4 is arranged on the frame 1, the mowing assembly 4 comprises a knife group mechanism 40 and a walking mechanism 41, the knife group mechanism 40 comprises a base 401, a knife group motor 402 and a mowing blade 403, the base 401 is arranged on the frame 1 and installed with two knife group motors 402, and the mowing blade 403 is connected to the output shaft of the knife group motor 402;

[0034] The walking mechanism 41 includes a mounting plate 410, a walking motor 411 and a main sprocket 412. The mounting plate 410 is arranged between the base 401 and the large frame 1. The walking motor 411 is installed on the mounting plate 410 and the output end is connected to the main sprocket 412. The main sprocket 412 is symmetrically provided with a secondary wheel 413 that rotates with the central axis and the mounting plate 410. The main sprocket 412 and the secondary wheel 413 are both connected with a synchronous chain 414. The central axis end surface of the secondary wheel 413 is connected with a walking gear 415, and the walking gear 415 is meshed with a walking rack 416 connected to the large frame 1 and the large frame extension kit 2.

[0035] The walking component 3 drives the entire lawn mower to move on the slope protection. When the knife group mechanism 40 is working, the knife group motor 402 is energized, driving the mowing blade 403 to rotate at high speed and laser weeding can be installed according to actual use requirements to achieve grass cutting. When the walking motor 411 is energized, its output end drives the main sprocket 412 to drive the secondary wheel 413 to rotate synchronously through the synchronous chain 414, and the walking gear 415 connected to the end face of the central axis of the secondary wheel 413 rotates together with the secondary wheel 413. The walking gear 415 can be engaged with the walking rack 416 to move. At the same time, the frame 1 can change the total length by adding or reducing the extended frame extension kit 2 to adapt to different slope protection. The rotation of the walking gear 415 is converted into a straight line up and down movement of the mowing component 4 on the frame 1, and the single cutting width of the mowing component 4 is 3 meters, thereby realizing the up and down walking of the mowing component 4 to adapt to different slope protections to cut weeds.

[0036] The present invention provides a self-propelled lawn mower for slope protection. Through the design of a large frame 1 and a large frame extension kit 2, the total length of the large frame 1 can be changed through the large frame extension kit 2 to meet the needs of slope protection of different lengths. The walking mechanism 41 achieves stable up and down movement of the mowing component 4 through the cooperation of a walking motor 411, a main sprocket 412, a secondary wheel 413, a synchronous chain 414, a walking gear 415 and a walking rack 416, which is convenient for cutting weeds on the slope protection and adapting to grass of different heights and slope protection terrain 41.

[0037] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] Please refer to Figure 1 A self-propelled slope protection special mower, whose walking component 3 includes a lithium battery box 30, a frame motor 31 and a crawler 32. The lithium battery box 30 is installed on the frame 1, and multiple frame motors 31 are installed on the frame 1 and the output shaft is connected to the crawler 32. The frame 1 is also equipped with a lifting electric hydraulic cylinder 33 whose output end is installed with the frame motor 31. An electric control cabinet 34 is installed on the side of the frame 1 away from the lithium battery box 30, and a transport vehicle 35 is slidably matched on the frame 1; the lithium battery box 30 supplies power to the frame motor 31, and the frame motor 31 drives the crawler 32 to rotate to make the mower walk. At the same time, the lifting electric hydraulic cylinder 33 adjusts the height of the frame motor 31 and then changes the contact height of the crawler 32 with the ground, so as to adapt to the height of different weeds, and the electric control cabinet 34 controls the electrical system, and the transport vehicle 35 on the frame 1 can move and walk on the frame 1 in the same way as the walking mechanism 41 to carry people / objects, thereby realizing the effect of flexible power supply and adaptive walking on weed cutting.

[0041] Through the cooperation of the lithium battery box 30, the track 32, and the lifting electric hydraulic cylinder 33, the lithium battery box 30 can provide electricity, and the track 32 cooperates with the electric hydraulic cylinder 33 to adapt to different slope protection, thereby improving the applicability of the equipment. The height of the lawn mower can be adjusted according to actual conditions to ensure the mowing effect.

[0042] Please refer to Figure 4-Figure 5A self-propelled slope protection lawn mower is provided, on which a telescopic electric support rod 417 is hingedly connected to a base 401, and an output end of the telescopic electric support rod 417 is connected to a rake 418 hingedly matched with the base 401; since the telescopic electric support rod 417 and the rake 418 are both hingedly connected to the base 401, when the walking state of the lawn mower changes, when the lawn mower walks upward for cutting, the telescopic electric support rod 417 is shortened, driving the rake 418 to be leveled, and the straightened rake 418 reduces the contact area with the slope and vegetation, thereby reducing the resistance of the lawn mower when walking upward, and when the lawn mower walks downward, the telescopic electric support rod 417 is extended, so that the rake 418 is perpendicular to the base 401, and the rake 418 can scrape the cut grass.

[0043] By adjusting the state of the rake guard 418 when the lawn mower moves upward and downward, it can better adapt to different work requirements. When moving upward, leveling the rake guard 418 can reduce resistance and avoid unnecessary interference; when moving downward, making the rake guard 418 vertical can effectively scrape and guide the cut grass, thereby improving mowing efficiency and cleaning effects.

[0044] A self-propelled slope protection lawn mower is further optimized, specifically, Figure 6 As shown, a swing mechanism 42 is provided on the mounting plate 410, and a swing effect is achieved between the mounting plate 410 and the base 401 through the swing mechanism 42. The swing mechanism 42 includes a waist-shaped guide groove 420, a guide shaft 421 and a tension spring 422. The waist-shaped guide groove 420 is symmetrically arranged on the mounting plate 410, the guide shaft 421 is installed on the base 401 and slidably cooperates with the waist-shaped guide groove 420, the tension spring 422 is connected to the guide shaft 421, and the base 401 is connected with visual sensor probes 423 around. When encountering an obstacle, the mounting plate 410 The waist-shaped guide groove 420 provides a movable space for the guide shaft 421 on the base 401. The collision force causes the guide shaft 421 to slide in the waist-shaped guide groove 420. At this time, the tension spring 422 connected to the guide shaft 421 is stretched or compressed. Once the obstacle is bypassed, the elastic force of the tension spring 422 pulls the mounting plate 410 back to its original position. At the same time, the visual sensor probes 423 around the base 401 continuously monitor the surrounding environment and transmit image information to the central control system. During the movement of the large frame 1, obstacles can be discovered in time, and avoidance or parking can be taken.

[0045] The swing mechanism 42 enables the lawn mower to automatically adjust the position of the cutting part when encountering an obstacle, thereby avoiding equipment damage caused by hard collision. The cooperation between the waist-shaped guide groove 420 and the guide shaft 421 and the elastic effect of the tension spring 422 enable the lawn mower to flexibly respond to obstacles of different sizes and shapes.

[0046] Further, such as Figure 6As shown, protective frames 424 are symmetrically installed on the base 401, and at least three anti-collision wheels 425 are connected to the two protective frames 424; when the lawn mower is working, the protective frames 424 symmetrically installed on the base 401 first contact the obstacle, and the anti-collision wheels 425 connected to the protective frames 424 will roll or slide on the surface of the obstacle as the lawn mower moves, and the anti-collision wheels 425 will play a buffering role. The rolling or sliding of the anti-collision wheels 425 enables the lawn mower to change direction or adjust position relatively smoothly when encountering an obstacle to avoid collision and damage.

[0047] The guard frame 424 and the anti-collision wheel 425 provide physical protection for the cutting part of the lawn mower. In the lawn mowing operation, various hard objects such as stones, branches, etc. are reduced from damaging the equipment, and the anti-collision wheel 425 can make the lawn mower more stable to adjust the position or change the direction.

[0048] A self-propelled slope protection lawn mower is further optimized, specifically, Figure 1-Figure 5 As shown, a laser probe connected to the central control system is installed on the transport vehicle 35, and the visual sensor probe 423 is distributed in a rectangular shape around the center of the base 401, and the visual sensor probe 423 is externally connected to the central control system; the laser probe on the transport vehicle 35 emits a laser beam to the surroundings and receives a reflected signal, so that when encountering an obstacle when carrying people / objects, it automatically stops. When the lawn mower is working, if it encounters an obstacle, the visual sensor probe 423 will feedback information in time, and the central control system controls the walking and cutting actions of the lawn mower to achieve automatic obstacle avoidance and precise mowing.

[0049] The laser probe can monitor the environment around the transport vehicle 35 in real time to avoid collision with obstacles during transportation, ensuring the safety and reliability of the transportation process. The sensor probe 423 can comprehensively monitor the environment around the base 401 from multiple angles, and avoidance measures can be taken in time during the movement of the large frame 1 and the lawn mower to avoid collision damage.
