[0007] Preferably, anti-slip support mechanisms are installed on both sides of the truss. The anti-slip support mechanism includes a sliding rod that is slidably mounted on the truss, a wheel seat fixedly mounted at the bottom of the sliding rod, and a rotating wheel rotatably mounted on the wheel seat. A spring is sleeved on the sliding rod, one end of the spring abuts against the bottom of the truss, and the other end of the spring abuts against the top of the wheel seat. A limiting plate is fixedly mounted on the top of the sliding rod. Further, the truss is provided with a sliding hole that allows the sliding rod to pass through. The sliding rod is slidably mounted in the sliding hole. The sliding rod is a square rod or a polygonal rod to prevent the sliding rod from rotating. The outer diameter of the limiting plate is larger than the inner diameter of the sliding hole. The limiting plate is used to prevent the top end of the sliding rod from detaching from the truss.

[0008] Preferably, the drive wheel assembly includes a mounting base mounted on the bottom of the support frame, an adjusting arm hinged to the mounting base, a second drive cylinder, and a drive wheel rotatably mounted on the adjusting arm. One end of the second drive cylinder is hinged to the mounting base, and the other end of the second drive cylinder is hinged to the adjusting arm.

Further, the second rotary actuator is preferably a hydraulic motor, but an electric motor or a pneumatic motor can also be used.

[0009] Preferably, a hay-raking mechanism is installed on the slide block.

[0014] Compared with the prior art, this utility model provides a slope mower with the following advantages: When the first drive cylinder is activated, its output end shortens, and the upper parts of the two supports move synchronously towards the middle of the truss until the two supports form an "eight" shape. This lowers the center of gravity of the entire mower, causing the rotating blades to contact the roots of weeds on the slope. The first rotary drive drives the rotating blades to rotate at high speed, and the transverse drive drives the weeding components to move back and forth along the truss. The drive wheel set moves the mower on the slope, effectively removing weeds from the entire slope. With a lowered center of gravity, the mower is less likely to slide down the slope, greatly improving its stability. Operators do not need to follow the mower, making it suitable for slope mowing needs. It eliminates the need for manual operation, reducing manual labor and improving mowing efficiency.

[0023] As described in the background art, a slope weeding device is used. The slope has a certain degree of inclination, and it is inconvenient to move the weeding device on the slope by manual control, so the efficiency of slope weeding needs to be further improved.

[0024] To solve this technical problem, this utility model provides a slope weeding machine, which is used for slope weeding and maintenance.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1

[0028] Please refer to Figure 1-6A slope trimmer includes: a slope body 1 and a trimming mechanism. The trimming mechanism includes a truss 2, an adjustable walking drive assembly mounted on both sides of the truss 2, a slide block 3 slidably mounted on the truss 2, and a trimming assembly mounted on the slide block 3. The inclined end faces of the truss 2 and the slope body 1 are arranged in parallel. A transverse drive for driving the slide block 3 to reciprocate is mounted on the slide block 3. The trimming assembly includes a first rotary drive 4 fixedly mounted on the slide block 3 and a rotary cutter 5 mounted on the output end of the first rotary drive 4. The adjustable walking drive assembly includes a support frame 6 hinged to the end of the truss 2, a set of drive wheels fixedly mounted on both sides of the bottom of the support frame 6, and a first drive cylinder 7 that provides power for the rotation of the support frame 6. Furthermore, the first rotary drive 4 is preferably a hydraulic motor, but an electric motor or a pneumatic motor can also be used; one end of the first drive cylinder 7 is hinged to the truss 2, and the other end of the first drive cylinder 7 is hinged to the support 6. The first drive cylinder 7 is preferably a hydraulic cylinder, but an electric cylinder or a pneumatic cylinder can also be used. The drive wheel set provides power for the movement of the lawn mower; a hinge shaft is fixedly installed at the end of the truss 2, and the support 6 is rotatably installed on the hinge shaft. The support 6 and the truss 2 are hinged together by the hinge shaft; the transverse drive can be a hydraulic slide, or other equivalent components that drive the slide 3 to reciprocate along the truss 2.

[0029] For details, please refer to Figure 5 The transverse drive includes a third rotary drive 22 fixedly mounted on the slide 3 and a gear mounted on the output end of the third rotary drive 22. A rack 23 is fixedly mounted on the truss 2, and the gear meshes with the rack 23. Furthermore, the third rotary drive 22 is preferably a hydraulic motor, but an electric motor or a pneumatic motor can also be used. A slide rail is mounted on the truss 2, and the slide 3 is slidably mounted on the slide rail.

[0030] For details, please refer to Figure 6 The truss 2 is equipped with anti-slip support mechanisms on both sides. The anti-slip support mechanisms include a sliding rod 8 that is slidably mounted on the truss 2, a wheel seat 9 that is fixedly mounted on the bottom of the sliding rod 8, and a rotating wheel 10 that is rotatably mounted on the wheel seat 9. A spring 11 is fitted on the sliding rod 8. One end of the spring 11 abuts against the bottom of the truss 2, and the other end of the spring 11 abuts against the top of the wheel seat 9. A limit plate 12 is fixedly mounted on the top of the sliding rod 8. Furthermore, the truss 2 is provided with a sliding hole that allows the sliding rod 8 to pass through. The sliding rod 8 is slidably mounted in the sliding hole. The sliding rod 8 is a square rod or a polygonal rod to prevent the sliding rod 8 from rotating. The outer diameter of the limit plate 12 is larger than the inner diameter of the sliding hole. The limit plate 12 is used to prevent the top end of the sliding rod 8 from detaching from the truss 2. When the spring 11 is naturally extended, the bottom of the rotating wheel 10 is 20-30cm higher than the bottom of the drive wheel assembly. In the non-mowing state, the rotating wheel 10 avoids interfering with the movement of the lawnmower. More specifically, the rotating wheel 10 is perpendicular to the truss 2.

[0031] The slope mower provided in this embodiment drives the gear to rotate via the third rotary drive 22, causing the gear to move along the rack 23 to achieve reciprocating movement of the slide block 3 on the truss 2. When the output end of the first drive cylinder 7 shortens, the upper parts of the two supports 6 move towards the middle of the truss 2 simultaneously, while the drive wheel sets at the bottom of the two supports 6 move away from each other until the bottom of the rotating wheel 10 contacts the inclined end face of the slope body 1. Under the action of the spring 11, the rotating wheel 10 can maintain good contact with the inclined slope surface of the slope body 1 during the mowing process, depending on the descent height of the truss 2. This increases the contact area between the mower and the inclined end face of the slope body 1, thereby improving the friction between the mower and the slope body 1 and effectively preventing the mower from sliding down from the inclined end face of the slope body 1, ensuring the smooth progress of the mowing operation.

[0032] Example 2

[0033] The slope trimmer provided in Example 1 has been further optimized. For details, please refer to [link / reference]. Figure 4 and Figure 6 The drive wheel assembly includes a mounting base 13 mounted on the bottom of the support frame 6, an adjusting arm 14 hinged to the mounting base 13, a second drive cylinder 15, and a drive wheel 16 rotatably mounted on the adjusting arm 14. One end of the second drive cylinder 15 is hinged to the mounting base 13, and the other end of the second drive cylinder 15 is hinged to the adjusting arm 14. A second rotary actuator 17 is mounted on the adjusting arm 14 to provide power for the rotation of the drive wheel 16. Furthermore, the second rotary actuator 17 is preferably a hydraulic motor, but an electric motor or a pneumatic motor can also be used.

[0034] For details, please refer to Figure 6 The mounting base 13 is rotatably mounted on the support frame 6, and the support frame 6 is equipped with a rotary cylinder 24 that provides power for the rotation of the mounting base 13; furthermore, the rotary cylinder 24 is preferably a hydraulic rotary cylinder, but an electric rotary cylinder or a pneumatic rotary cylinder can also be used.

[0035] The slope mower provided in this embodiment can further adjust its height by activating the second drive cylinder 15, which increases or decreases the angle between the adjusting arm 14 and the mounting base 13. Each drive wheel group is independently controlled. When the slope body 1 is uneven, the height of each drive wheel group is adjusted to keep the truss 2 in a horizontal state, ensuring smooth mowing operations and improving the applicability of the mower to different terrains. When the drive wheel 16 is perpendicular to the truss 2, the second rotary drive 17 drives the drive wheel 16 to rotate, allowing the mower to slide left and right along the slope body 1. The rotary cylinder 24 drives the mounting base 13 to rotate, making the drive wheel 16 parallel to the truss 2. This allows the mower to move up and down along the slope body 1 to meet the mowing needs of large-area slopes and facilitates the mower's self-movement from the slope body 1, further improving operational convenience.

[0036] Example 3

[0037] For details, please refer to Figure 3 and Figure 5 The slide block 3 is equipped with a hay-raking mechanism, which includes a lifting frame 18 that slides up and down on the slide block 3 and hay-raking components installed on the lifting frame 18. The slide block 3 is equipped with a third drive cylinder 19 that provides power for the lifting frame 18 to slide up and down. Furthermore, the lifting frame 18 is installed at the output end of the third drive cylinder 19. The third drive cylinder 19 is preferably a hydraulic cylinder, but a pneumatic cylinder or an electric cylinder can also be used.

[0038] For details, please refer to Figure 5 The hay-raking component includes a hay rake 20 and multiple torsion springs 21. One end of the torsion spring 21 is fixedly installed on the lifting frame 18, and the other end of the torsion spring 21 is fixedly connected to the hay rake 20.

[0039] Specifically, it also includes a power supply mechanism 25 installed on one of the support frames 6; furthermore, the power supply mechanism 25 is preferably a hydraulic pump station, but a diesel generator or an air pump can also be used; the power supply mechanism 25 provides driving power to the first drive cylinder 7, the second drive cylinder 15, the third drive cylinder 19, the first rotary drive 4, the second rotary drive 17 and the third rotary drive 22.

[0040] In this embodiment, when the sliding block 3 moves downward from the upper part of the slope body 1, the output end of the third drive cylinder 19 extends, and the rake 20 moves downward and contacts the upper part of the slope body 1. The rake 20 scrapes the cut weeds to the lower part of the slope body 1. When the sliding block 3 moves upward from the lower part of the slope body 1, the output end of the third drive cylinder 19 shortens, and the rake 20 moves upward, avoiding interference with the sliding of the sliding block 3. Under the action of the torsion spring 21, elastic contact can be achieved between the rake 20 and the inclined end face of the slope body 1, avoiding interference from stones or other objects on the slope body 1 on the movement of the rake 20, and ensuring the smooth progress of the rake operation.

[0041] The usage process of the slope mower provided by this utility model is as follows: The mower is placed on the slope body 1, the truss 2 is parallel to the inclined end face of the slope body 1, the output end of the first drive cylinder 7 is shortened, the upper part of the two supports 6 moves towards the middle of the truss 2 in sync until the two supports 6 form an "eight" shape, the bottom of the rotating wheel 10 contacts the slope body 1, the center of gravity of the entire mower shifts downward, the rotating blade 5 contacts the roots of the weeds on the slope body 1, the first rotating drive 4 drives the rotating blade 5 to rotate at high speed, the transverse drive drives the weeding component to move back and forth along the truss 2, and the drive wheel set drives the mower to move on the slope body 1 to cut the weeds on the slope body 1, and the cut weeds are collected at the bottom of the slope body 1 by the grass-raking mechanism.
