[0036] like Figures 1 to 4 As shown, the present embodiment provides a multi-directional adjustable trimming vehicle, which includes a vehicle body 1, a rotating support mechanism 2 and a trimming mechanism 3. The rotating support mechanism 2 is rotatably connected to the vehicle body 1 with a rotation axis perpendicular to the ground. The trimming mechanism 3 includes a flying arm 31, a tool holder assembly 32, a first hydraulic rotary assembly 33 and a cutter head 34; the flying arm 31 is rotatably connected to the rotating support mechanism 2 via a first rotation axis 24, and the first hydraulic rotary assembly 33 is fixed on the flying arm 31, wherein the first rotation axis 24 is parallel to the ground; the tool holder assembly 32 includes a first tool holder 321 and a second tool holder 322, the first tool holder 321 is connected to a driving end of the first hydraulic rotary assembly 33, the first hydraulic rotary assembly 33 can drive the first tool holder 321 to rotate via the second rotation axis, and the first end of the second tool holder 322 is rotatably connected to the second tool holder 322 via a third rotation axis 323, wherein the second rotation axis is perpendicular to the ground, and the direction of the second rotation axis is Figure 2The direction of the middle arrow E is parallel, and the third rotation axis 323 is parallel to the ground; the cutter head 34 includes a cutter head support body 341 and a blade 342, the cutter head support body 341 is connected to the second end of the second tool holder 322, and the blade 342 is rotatably set on the cutter head support body 341. First, the preliminary trimming direction is determined by adjusting the rotating support mechanism 2 and the flying arm 31. The rotating support mechanism 2 is rotatably connected to the vehicle body 1 with a direction perpendicular to the ground as the rotation axis, and can greatly adjust the left and right directions of the trimming mechanism 3. The multi-directional adjustment trimming vehicle is located on the road. By adjusting the rotating support mechanism 2, the trimming mechanism 3 can be turned as a whole to the bushes and weeds on both sides of the highway; the flying arm 31 is rotatably connected to the rotating support mechanism 2 with a direction parallel to the ground as the rotation axis, and can greatly adjust the up and down directions of the trimming mechanism 3, that is, the pitch angle, so that the position of the blade can be preliminarily adjusted within a larger range to approach the bushes and weeds to be trimmed; its The trimming position is further determined by adjusting the first hydraulic rotary assembly 33 and the tool holder assembly 32. The first hydraulic rotary assembly 33 can drive the first tool holder 321 to rotate with the direction perpendicular to the ground as the rotation axis, and the left and right directions of the trimming mechanism 3 can be further adjusted so that the cutting direction of the blade 342 is parallel to the direction of the vehicle's travel, so that the branches can be trimmed better and avoid occupying other lanes; the second tool holder 322 is connected to the first tool holder 321 with the direction parallel to the ground as the rotation axis, and the up and down directions of the trimming mechanism 3 can be further adjusted to achieve fine trimming position adjustment, and finally the target trimming object is trimmed by the blade 342. The body 1 of the multi-directional trimming vehicle occupies less lanes and does not affect the normal passage of other vehicles. At the same time, the trimming angle of the multi-directional trimming vehicle is easy to adjust, and the bushes and weeds on both sides of the highway can be trimmed without dead angles.

[0037] Furthermore, the rotating support mechanism 2 includes a column 21 and a boom 22; one end of the column 21 is rotatably connected to the vehicle body 1 with a direction perpendicular to the ground as the rotation axis, and the column 21 is adjusted left and right relative to the vehicle body 1 on a plane parallel to the ground, and the trimming position is preliminarily determined in the horizontal direction. The multi-directional adjustment trimming vehicle is located on the road, and the trimming mechanism 3 can be oriented as a whole toward the bushes and weeds on both sides of the highway by adjusting the column 21; one end of the boom 22 is rotatably connected to the other end of the column 21 through a fourth rotation axis 25, wherein the fourth rotation axis 25 is parallel to the ground, and the boom 22 is adjusted up and down in the height direction relative to the column 21, and the trimming position is preliminarily determined in the height direction; the flying arm 31 is rotatably connected to the other end of the boom 22 through the first rotation axis 24, wherein the first rotation axis 24 is parallel to the ground, and the flying arm 31 is adjusted up and down in the height direction relative to the boom 22, and the trimming position is further determined in the height direction. By adjusting the pitch angle in sections through the boom 22 and the flying arm 31, the space between the vehicle and the position to be pruned can be saved, the vehicle is prevented from occupying too wide a road, and multi-angle fine adjustment can be achieved to improve the pruning effect.

[0038] Furthermore, the rotary support mechanism 2 further includes a luffing cylinder 23, one end of which is rotatably connected to the column 21, and the other end of which is rotatably connected to the boom 22. The luffing cylinder 23 drives the boom 22 to rotate relative to the column 21 through the fourth rotation axis 25. The luffing cylinder 23 provides power for the rotation of the boom 22, so that the boom 22 is adjusted up and down in the height direction relative to the column 21, and the trimming position of the multi-directional adjustable trimming vehicle in the height direction is preliminarily determined.

[0039] Specifically, the trimming mechanism 3 further includes a fly arm cylinder 35, one end of which is rotatably connected to the fly arm 31, and the other end of which is rotatably connected to the boom 22. The fly arm cylinder 35 drives the fly arm 31 to rotate relative to the boom 22 through the first rotation axis 24. For example, a first connecting plate is provided on the boom 22, and a second connecting plate and a third connecting plate are provided at both ends of the fly arm 31, one end of the first connecting plate is rotatably connected to the second connecting plate, and the other end is rotatably connected to the first end of the fly arm cylinder 35, and the second end of the fly arm cylinder 35 is rotatably connected to the third connecting plate, for example, both are rotatably connected through a rotating shaft. The fly arm cylinder 35 provides power for the rotation of the fly arm 31, so that the fly arm 31 is adjusted up and down in the height direction relative to the boom 22, and further determines the trimming position of the multi-directional adjustment trimming vehicle in the height direction.

[0040] Preferably, the first hydraulic rotary assembly 33 includes a first rotary bearing, a first hydraulic motor and a first mounting platform. The first hydraulic motor is driven to connect to the first rotary bearing. The first rotary bearing includes an inner ring and an outer ring that are nested and rotated inside and outside. The inner ring and the outer ring are connected to each other through a rotor group. For example, a driving gear or a worm is connected to the driving end of the first hydraulic motor. The driving gear or the worm is meshed with the outer ring of the rotary bearing, thereby driving the inner ring to rotate. The first mounting platform is fixedly connected to the inner ring. The rotation of the inner ring drives the first mounting platform to rotate. The first tool holder 321 is connected to the first mounting platform. The first hydraulic motor drives the first mounting platform to rotate through the first rotary bearing, so that the first mounting platform rotates through the second rotation axis perpendicular to the ground, thereby driving the first tool holder 321 to rotate through the second rotation axis perpendicular to the ground, and the left and right directions of the trimming mechanism 3 can be further adjusted. The first rotary bearing has the characteristics of light weight, flexible rotation, strong bearing capacity, convenient assembly and long service life, and can be widely used in the rotation connection of a multi-directional adjustable trimming vehicle. Under the power of the first hydraulic motor, the driving end of the first slewing bearing rotates around its own axis, that is, rotates through the second rotation axis perpendicular to the ground, thereby driving the first tool holder connected to the driving end of the first slewing bearing to rotate through the second rotation axis perpendicular to the ground. It should be noted that the first slewing bearing is a relatively mature existing technology, so it will not be described in detail here.

[0041] Exemplarily, the trimming mechanism 3 also includes a support plate, and the first hydraulic rotary assembly 33 is arranged on the support plate, and the support plate is fixedly connected to the flying arm 31. Since the first hydraulic motor drives the first tool holder 321 to rotate through the second rotation axis perpendicular to the ground through the first rotary bearing, the first tool holder 321 rotates relative to the flying arm 31 through the second rotation axis perpendicular to the ground, and the first hydraulic rotary assembly 33 is fixedly connected to the flying arm 31 through the support plate.

[0042] More preferably, the trimming mechanism 3 further includes a tool holder adjustment cylinder 36. A mounting plate is provided on the first mounting platform. The first end of the tool holder adjustment cylinder 36 is rotatably connected to the mounting plate. The second end of the tool holder adjustment cylinder 36 is rotatably connected to the second tool holder 322. The tool holder adjustment cylinder 36 drives the second tool holder 322 to rotate relative to the first tool holder 321 through the third rotation axis 323. The tool holder adjustment cylinder 36 provides power for the rotation of the second tool holder 322, so that the second tool holder 322 is adjusted up and down in the height direction relative to the first tool holder 321, and finally determines the trimming position of the multi-directional adjustment trimming vehicle in the height direction, realizes the adjustment of a small angle, and improves the accuracy of the trimming position.

[0043] Specifically, the trimming mechanism 3 further includes a first connecting rod 37 and a second connecting rod 38, wherein the first end of the first connecting rod 37 is rotatably connected to the first tool holder 321, the first end of the second connecting rod 38 is rotatably connected to the second tool holder 322, and the second end of the first connecting rod 37 and the second end of the second connecting rod 38 are coaxially rotatably connected to the second end of the tool holder adjusting oil cylinder 36. By providing the second connecting rod 38, the tool holder adjusting oil cylinder 36 can drive the second tool holder 322 to rotate relative to the first tool holder 321. In addition, since the first connecting rod 37 is rotatably connected to the first tool holder 321, the stability of the second tool holder 322 rotating relative to the first tool holder 321 is enhanced.

[0044] More specifically, the second connecting rod 38 is arc-shaped, which can adapt to the rotation angle and avoid interference with other structures, so that the tool holder adjusting cylinder 36 can smoothly drive the second tool holder 322 to rotate relative to the first tool holder 321.

[0045] like Figure 5 As shown, a plurality of blades 342 are provided, and the plurality of blades 342 are arranged at intervals along the same plane. Three blades are provided in the figure. Of course, in other embodiments, the blade 342 may be provided as two, four, etc., which is determined according to actual conditions. The provision of a plurality of blades 342 can maximize trimming and increase trimming efficiency.

[0046] Furthermore, the blade support 341 is detachably connected to the second end of the second blade holder 322. For example, the detachable connection is achieved by threaded connection, so that the blade support 341 with blades 342 of different sizes can be replaced to adapt to different trimming situations. Of course, in other embodiments, the detachable connection can also be achieved by means of latches, etc., which is determined according to actual conditions.

[0047] Specifically, the cutter head support body 341 is adjustably connected to the second end of the second cutter holder 322 with the length direction of the second cutter holder 322 as the rotation axis, so that the cutter head support body 341 can be rotated and adjusted in a plane perpendicular to the length direction of the second cutter holder 322, thereby driving the adjustment of the direction of the plane where the blade 342 is located, which is convenient for trimming at different angles.

[0048] More specifically, in this embodiment, a first mounting flange is provided at the second end of the second tool holder 322, and a plurality of first screw holes are provided on the first mounting flange with the length direction of the second tool holder 322 as the center axis and the spacer ring is provided, and a second mounting flange is provided on the cutter head support body 341, and a plurality of second screw holes are provided on the second mounting flange with the length direction of the cutter head support body 341 as the center axis and the spacer ring is provided, and each bolt passes through a first screw hole and is selectively connected with a second screw hole, wherein the first mounting flange, the second mounting flange and the bolt constitute a cutter head left-right adjustment assembly 39. The direction of the second tool holder 322 is determined according to the direction of the cutter head 34 at the required trimming position, and the cutter head left-right adjustment assembly 39 is adjusted, and the cutter head support body 341 in the direction is connected to the second tool holder 322 correspondingly, and the first screw hole and the second screw hole required for connection are determined, and the corresponding first screw hole and the second screw hole are fixedly connected by bolts to achieve the direction adjustment of the blade 342.

[0049] In another embodiment, the cutter head left-right adjustment assembly 39 can be replaced by a second hydraulic rotary assembly, which is fixed at the second end of the second tool holder 322. The second hydraulic rotary assembly includes a second rotary bearing, a second hydraulic motor and a second mounting platform. The second hydraulic motor is driven to connect to the second rotary bearing. The second rotary bearing includes an inner ring and an outer ring that are nested and rotated inside and outside. The inner ring and the outer ring are connected to each other through a rotor group. For example, the driving end of the second hydraulic motor is connected to a driving gear or a worm, which is meshed with the outer ring of the rotary bearing to drive the inner ring to rotate. The second mounting platform is fixedly connected to the inner ring, and the rotation of the inner ring drives the second mounting platform to rotate. The cutter head support body 341 is connected to the second mounting platform. The second hydraulic motor drives the second mounting platform to rotate through the second rotary bearing, so that the second mounting platform rotates with the length direction of the second tool holder 322 as the rotation axis, thereby driving the cutter head support body 341 to rotate with the length direction of the second tool holder 322 as the rotation axis, and the left-right direction of the cutter head 34 can be further adjusted. The second slewing bearing has the characteristics of light weight, flexible rotation, strong bearing capacity, easy assembly and long service life, and can be widely used in the rotation connection of the multi-directional adjustable trimming vehicle. Under the power of the second hydraulic motor, the driving end of the second slewing bearing rotates around its own axis, that is, it rotates with the length direction of the second tool holder 322 as the rotation axis, thereby driving the cutter head support body 341 connected to the driving end of the second slewing bearing to rotate with the length direction of the second tool holder 322 as the rotation axis. It should be noted that the second slewing bearing is a relatively mature existing technology, so it will not be described in detail here.

[0050] Preferably, in the present embodiment, legs are further provided on both sides of the vehicle body 1, and both legs are rotatably connected to the vehicle body 1 with the width direction of the vehicle body 1 as the rotation axis. A fourth oil cylinder is provided on the legs, and the fourth oil cylinder provides power for the rotation of the legs. When the multi-directional adjustable mowing vehicle is in a driving state, the fourth oil cylinder is driven to drive the legs to rotate and retract with the width direction of the vehicle body 1 as the rotation axis, which is convenient for the driving of the multi-directional adjustable mowing vehicle. When the multi-directional adjustable mowing vehicle is in a mowing state, the fourth oil cylinder is driven to drive the legs to rotate and retract with the width direction of the vehicle body 1 as the rotation axis and placed on the ground, which further ensures the balance of the vehicle body 1 and increases the safety of the mowing process.
