[0033] Example 1

[0034] Reference Figures 1-3 and Figure 6 The first embodiment of the present invention provides a front-end floating mowing device suitable for plateau areas, including a mounting component 100 and a cutting component 200 movably disposed on the mounting component 100; a floating adjustment component 300 is disposed between the mounting component 100 and the cutting component 200, and the floating adjustment component 300 can assist the floating of the cutting component 200.

[0035] The cutting assembly 200 includes a cutter head 201, four blades 202 fixedly mounted on the cutter head 201, a fixed plate 203 fixedly disposed inside the cutter head 201, a buffer portion 204 disposed on the fixed plate 203, and a fixing sleeve 205 disposed on the buffer portion 204; the four blades 202 are arranged in a ring on the cutter head 201 near the edge, four buffer portions 204 are provided, and the fixing sleeve 205 is disposed in the middle of the four buffer portions 204. The buffer portions 204 can ensure that the cutting assembly 200 provides horizontal buffering, enhance the adaptability of the device, and improve the service life of the device.

[0036] The mounting assembly 100 includes a mounting bracket 101, a support rod 102 rotatably mounted on the mounting bracket 101, and a mounting ball 103 fixedly mounted at the bottom end of the support rod 102. The mounting ball 103 is movably mounted inside a fixing sleeve 205. The front view of the fixing sleeve 205 is a semi-circle, which can prevent the mounting ball 103 from falling off. The shape inside the fixing sleeve 205 matches the outer surface of the mounting ball 103.

[0037] In summary, the cutting component 200 and the mounting component 100 are movably connected by the mounting ball 103 and the fixing sleeve 205, allowing the cutting component 200 to move at multiple angles to adapt to plateau terrain with different slopes. It can also be adjusted according to actual needs to accommodate uneven ground, and can deflect at multiple angles such as forward, backward, left, and right. The floating adjustment component 300 can play an auxiliary role in the multi-angle adjustment of the cutting component 200.

[0038] Example 2

[0039] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the floating adjustment component 300 includes a connecting ring 301 fixedly disposed on the upper side of the fixed plate 203, a cover 302 fixedly disposed on the connecting ring 301, a mating part 304 disposed on the cover 302, and a cylinder 303 fixedly disposed on the bottom of the mounting bracket 101; the cylinder 303 abuts against the upper surface of the cover 302.

[0040] The cover 302 not only protects the cutting assembly 200, but also replaces the cutter head 201 and works with the cylinder 303 to prevent wear of the cutter head 201 caused by contact between the cutter head 201 and the cylinder 303. An auxiliary ring 302d is provided on the top of the cover 302. The auxiliary ring 302d is made of nylon material. The bottom of the cylinder 303 is coated with polytetrafluoroethylene to protect the bottom of the cylinder 303.

[0041] There are four sets of cylinders 303, which are arranged in a ring around the support rod 102. When a part of the cutter head 201 is subjected to force and tilts upward, the cover 302 will compress the cylinders 303 near that part to extend and retract, while the bottom of the cylinders 303 away from that part will extend. When the force is removed, the cutter head 201 and the cover 302 will rebound to their original horizontal state under the action of the cylinders 303. The cylinders 303 in this device play a role similar to a spring, but the cylinders 303 are more stable than springs.

[0042] The mating part 304 includes a fixing member 304a inserted into the cover 302, a threaded rod 304b threaded to the inside of the fixing member 304a, a control block 304c fixedly disposed at the lower part of the threaded rod 304b, a fixing cover 304d fixedly disposed at the bottom end of the threaded rod 304b, and a movable ball 304e movably disposed in the fixing cover 304d; the cover 302 has a mating groove 302a, the fixing member 304a is disposed in the mating groove 302a, the outer surface of the control block 304c has multiple flat surfaces that facilitate clamping, and the edge of the cross-section of the control block 304c is hexagonal, which facilitates the tool clamping operation of the control block movement.

[0043] A groove 302b is formed in the mating groove 302a, and a spring sleeve 304f is fitted inside the groove 302b. The vertical cross-section of the spring sleeve 304f is "C" shaped. A mating ring 304g is fixedly provided on the side of the fixing member 304a. The mating ring 304g is inserted into the spring sleeve 304f, and the spring sleeve 304f can limit the fixing member 304a. The radius of the mating groove 302a is larger than the radius of the fixing member 304a. The mating ring 304g on the fixing member 304a limits the fixing member 304a by the spring sleeve 304f. The spring sleeve 304f can provide multi-angle buffer for the fixing member 304a. The mating groove 302a also provides buffer space for the fixing member 304a, which greatly reduces the probability of the mating member being damaged.

[0044] The movable ball 304e is designed to cause rolling friction between the mating part 304 and the ground during contact, thereby reducing the friction between the mating part 304 and the ground, alleviating friction at the bottom of the mating part 304, and increasing the service life of the mating part 304. The threaded rod is designed to facilitate the replacement of damaged movable balls and fixed covers 304d by the staff. When replacing, simply use a tool to clamp the control block 304c, unscrew the threaded rod 304b, and then replace it with a new one, which brings convenience to the staff's maintenance work.

[0045] There are four sets of mating parts 304. The four sets of mating parts 304 are arranged in a ring around the support rod 102. The mating parts 304 are all located near the edge of the cover 302. The positions of the four mating parts 304 correspond one-to-one with the positions of the four cylinders 303. There are also four sets of mating grooves 302a and grooves 302b, which correspond to the positions of the four sets of mating parts 304.

[0046] During operation, the movable ball 304e of the mating part contacts the ground. When the terrain changes, one or more mating parts 304 that contact the ground can cause the cover 302 to deflect accordingly. The cover 302 can cause the cutter head 201 to deflect synchronously. When the cover 302 deflects, it can cause the corresponding cylinder 303 to be compressed and shortened. The corresponding cylinder 303 automatically extends. As the terrain continues to change, the blade 202 can rotate accordingly. The bottom end of the cylinder 303 is always in contact with the upper surface of the cover 302, providing appropriate pressure to the cover 302 while preventing the cutter head 201 from deflecting out of control, so that the cutter head 201 can float and adapt to changes in terrain.

[0047] The remaining structure is the same as that in Example 1.

[0048] Example 3

[0049] Reference Figures 6-10 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: a buffer groove 204a is provided in the fixed plate 203, and multiple sets of buffer parts 204 are provided. There are four sets of buffer parts 204, and the four sets of buffer parts 204 are arranged in a ring around the central axis of the support rod 102. There are also four sets of buffer grooves 204a, and the positions of the four sets of buffer grooves 204a correspond one-to-one with the positions of the four sets of buffer parts 204.

[0050] The buffer section 204 includes a mounting block 204b fixedly disposed on the side of the fixed sleeve 205, a threaded rod 204f fixedly disposed on the mounting block 204b away from the fixed sleeve 205, a movable rod 204c slidably disposed in the buffer groove 204a, a control block 204d fixedly disposed on the circumferential surface of the threaded rod 204f, a spring 204e fixedly disposed between the movable rod 204c and the fixed plate 203, the threaded rod 204b being threadedly connected to the movable rod 204c, the spring 204e being sleeved on the movable rod 204c, and the outer surface of the control block 304c having multiple flat surfaces for easy clamping, facilitating tool clamping and control.

[0051] Furthermore, the buffer 204 can provide horizontal cushioning for the cutting assembly 200, especially when the cutting assembly 200 moves and the cover 302 or the mating part 304 hits or bumps into hard stones or protruding ground, the buffer 204 can provide a certain amount of cushioning for the cutting assembly 200 and play a protective role for the cutting assembly 200; the spring 204e can play a cushioning role, and the four sets of buffers 204 are evenly distributed around, which can provide cushioning for the force on each side of the cutting assembly 200, and the number of buffers 204 can be increased, with more sets provided to provide more sufficient cushioning.

[0052] Furthermore, by using the tool to hold the control block 204d and rotate it, the movable rod 204c can be controlled to slide within the buffer groove 204a. The operator can unscrew the threaded rod 204f by rotating the control block 204d. After unscrewing all four threaded rods 204f, the cutting assembly 200 can be removed. In high-altitude areas with complex terrain, this makes it easier for operators to carry. Removing it for carrying can also avoid some damage that may occur during transportation to a certain extent. Removing it also makes maintenance more convenient.

[0053] The fixed plate 203 is also provided with a protective component 400; the protective component 400 includes a protective cover 401 fixedly installed at the bottom of the fixed plate 203, a movable part 402 inserted into the protective cover 401, a movable cover 403 fixedly installed on the movable part 402, a limiting sleeve 404 fixedly installed on the movable cover 403, and a movable ball 405 movably installed in the limiting sleeve; the protective cover 401 can block the buffer part 204 from the bottom, separating the buffer part 204 from the ground, preventing the ground debris from damaging the buffer part 204 and other components, the movable cover 403 has a space inside that can accommodate the movement of the movable ball 405, the shape of the inner side of the limiting sleeve 404 matches the shape of the middle part of the movable ball 405, which can limit the movement of the movable ball 405, prevent the movable ball 405 from deviating, and the movable ball 405 can directly contact the ground, providing support for the device and reducing the pressure on the movable ball 304e.

[0054] A second spring 406 is sleeved on the movable part 402. The second spring 406 is located between the protective cover 401 and the movable cover 403. The second spring 406 is relatively stiff, but it can still play a role in buffering and shock absorption for the protective component 400.

[0055] The remaining structure is the same as that in Example 2.
