Description

Technical Field

[0001] This utility model belongs to the field of auxiliary mechanical equipment, and in particular relates to a multi-functional work vehicle. Background Technology

[0002] With the continuous advancement of agricultural modernization, intelligent agricultural machinery is playing an increasingly important role in improving agricultural production efficiency and reducing labor intensity. However, in complex terrain areas such as hilly and mountainous regions and orchards in my country, traditional agricultural machinery generally suffers from poor adaptability, low operating efficiency, and low level of intelligence due to the limitations of natural conditions such as large terrain undulations, steep slopes, scattered plots, and numerous obstacles. This seriously restricts the mechanization development of agriculture in mountainous areas.

[0003] Currently, most agricultural machinery on the market is designed for plains areas. Its power system and walking mechanism are difficult to adapt to hilly and mountainous environments with a slope of more than 15°. It has problems such as insufficient climbing ability, poor stability, and inflexible steering. Especially in special agricultural scenarios such as mountain forests and orchards, the planting density of fruit trees is high, the row spacing is small, the ground is uneven, and there are often obstacles such as rocks, tree roots, and ditches. Traditional agricultural machinery is difficult to enter and operate, and manual operation is inefficient and poses safety hazards.

[0004] Therefore, to solve the above problems, a multi-functional work platform is needed that can move stably in complex terrain conditions, achieving the goals of multi-purpose operation, precise operation, and green and efficient operation. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a multi-functional work vehicle to solve the technical problems in the prior art, such as the difficulty of traditional agricultural machinery to enter the work area, low efficiency of manual operation, and safety hazards.

[0006] To achieve the above and other related objectives, this utility model provides a multi-functional work vehicle, including a mobile chassis, wherein the mobile chassis is a tracked mobile chassis, and a frame is horizontally fixedly installed on the upper side of the mobile chassis, and further comprising:

[0007] A lifting mechanism is fixedly installed above the frame via a mounting bracket.

[0008] A vehicle stability mechanism is fixedly mounted on the mobile chassis and symmetrically arranged on both sides of the mobile chassis.

[0009] The tipping mechanism includes a tipping plate, a hinge seat, and a drive unit. The tipping plate is horizontally disposed at the top of the lifting mechanism. The drive unit and the hinge seat are respectively disposed below the two ends of the tipping plate in the length direction. The tipping plate is rotatably mounted on the top of the lifting mechanism through the hinge seat. The drive unit drives the tipping plate to rotate around the hinge seat.

[0010] In this way, the tracked mobile chassis enables the invention to move stably in complex terrain. The lifting mechanism serves two purposes: carrying goods and transporting workers to higher positions for pruning, daily observation and maintenance of fruit trees, as well as facilitating pollination, harvesting, or fruit thinning. The vehicle's stability mechanism further enhances worker safety during operations. When goods need to be transported to higher positions, the tipping mechanism facilitates unloading, reducing the workload for workers.

[0011] Optionally, the drive unit includes a mounting platform, a motor, a rack, a rolling wheel, and a drive roller. The mounting platform is fixedly installed at the end of the lifting mechanism away from the hinge seat, located below the tilting plate. The mounting platform has a clearance groove and a mounting groove passing through the clearance groove. The rack is vertically installed in the mounting groove via a linear slide rail module. The rolling wheel is rotatably installed on the upper end of the rack via the mounting seat, and the rolling wheel and the lower side of the tilting plate are in close rolling contact. The drive roller is rotatably installed on the mounting platform via a bracket, and the drive roller has teeth that mesh with the rack. The motor is fixedly installed on the mounting platform, and one end of the drive roller and the output end of the motor are meshed by a gear. The motor drives the drive roller to rotate, thereby moving the rack meshing with the drive roller. During the upward movement of the rack, the rolling wheel lifts the tilting plate upward. Due to the action of the hinge seat, the tilting plate rotates around the hinge seat, thereby tilting the tilting plate to facilitate unloading of heavy objects.

[0012] Optionally, the slider of the linear slide rail module is fixedly installed in the mounting groove, and the slide rail of the linear slide rail module is fixedly installed on the rack and arranged parallel to each other along the length direction. Using the linear slide rail module makes the movement of the rack more stable, preventing the rack from shifting during movement and facilitating the lifting of the flip plate.

[0013] Optionally, the lifting mechanism is a scissor lift mechanism, including a lifting plate, a drive telescopic rod, and a scissor hinge frame. The upper and lower ends of the scissor hinge frame are equipped with second hinge seats. The lower end of the scissor hinge is mounted on the upper side of the mounting frame via the second hinge seats, and they are symmetrically arranged. Two scissor hinge frames are connected by a connecting plate. The upper end of the scissor hinge frame is mounted on the lower side of the lifting plate via the second hinge seats. The lifting plate is horizontally arranged. The two ends of the drive telescopic rod are respectively mounted on the mounting frame and the connecting plate via third hinge seats. The drive telescopic rod is located between the scissor hinge frames. Using a scissor lift mechanism can increase the lifting height and reduce the overall size of the work vehicle during retrieval, resulting in a low space occupancy rate and better adaptability to complex working environments.

[0014] Optionally, the flip plate is fitted onto the upper side of the lifting plate and is rotatably connected to the lifting plate via the hinge seat located at one end of the lifting plate, and the mounting platform is fixedly installed on the end of the lifting plate away from the hinge seat.

[0015] Optionally, the frame is rectangular, and the vehicle stability mechanism is located at the four corners of the frame, on the outside of the mobile chassis. The vehicle stability mechanism includes hydraulic rods and support feet. The hydraulic rods are vertically mounted on the frame with their actuating ends facing downwards, and the support feet are fixedly mounted on the top of the actuating ends of the hydraulic rods. By placing hydraulic rods and support feet at the four corners, the independently operating hydraulic rods can extend to different lengths, ensuring the levelness of the entire vehicle body during operation in sloping ground conditions, thus improving safety.

[0016] Optionally, a storage cavity is provided between the frame and the mounting bracket. This storage cavity increases storage capacity.

[0017] Optionally, the front end of the mobile chassis is symmetrically provided with an auxiliary motion mechanism. The auxiliary motion mechanism includes a mounting plate, an electric telescopic column, auxiliary rollers, and a roller mounting frame. One end of the mounting plate is rotatably mounted on the mobile chassis. The moving end of the electric telescopic column is inclined downwards in a direction away from the mobile chassis and rotatably connected to the end of the mounting plate away from the mobile chassis. The fixed end of the electric telescopic column is rotatably connected to the mobile chassis and is located above the mounting plate. The roller mounting frame is rotatably mounted on the end of the mounting plate away from the mobile chassis, and the auxiliary rollers are rotatably mounted on the roller mounting frame. Using the auxiliary motion mechanism, when facing higher steps, the electric telescopic column and auxiliary rollers work together to support the auxiliary rollers on the steps as the mobile chassis moves forward. This allows the auxiliary rollers to roll onto the steps, facilitating the lifting of the tracks on the front of the mobile chassis and enabling them to press against the steps, thereby improving the mobile chassis's ability to climb stairs.

[0018] Optionally, the rotation direction of the roller mounting bracket is parallel to the axis of the electric telescopic column, the auxiliary rollers are evenly distributed circumferentially on the roller mounting bracket, and the rotation direction of the auxiliary rollers is parallel to the rotation direction of the roller mounting bracket.

[0019] Optionally, a control box is installed on the frame, and the control box is electrically connected to the various electrical components of the multi-functional work vehicle.

[0020] The beneficial effects of this utility model are as follows:

[0021] When using this utility model, it can achieve stable walking under complex terrain conditions and can be used for multiple purposes, providing equipment support for the development of hilly and mountainous areas and forestry and fruit industry. Attached Figure Description

[0029] like Figures 1-5 As shown, a multi-functional work vehicle includes: a mobile chassis 1, which is a tracked mobile chassis, and can achieve stable movement in complex terrain through the tracks.

[0030] In this embodiment, to enhance the climbing ability of the mobile chassis 1, an auxiliary motion mechanism 2 is symmetrically arranged on the mobile chassis 1. The auxiliary motion mechanism 2 includes a mounting plate 21, an electric telescopic column 22, auxiliary rollers 23, and a roller mounting frame 24. One end of the mounting plate 21 is rotatably mounted on the front end of the mobile chassis 1. The moving end of the electric telescopic column 22 is inclined downwards in the direction away from the mobile chassis 1 and is rotatably connected to the end of the mounting plate 21 away from the mobile chassis 1. The fixed end of the electric telescopic column 22 is located above the mounting plate 21 and is rotatably mounted on the mobile chassis 1. The roller mounting frame 24 is rotatably mounted on the end of the mounting plate 21 away from the mobile chassis 1. The rotation direction of the roller mounting frame 24 is parallel to the axis of the electric telescopic column 22. Four auxiliary rollers 23 are evenly distributed circumferentially on the roller mounting frame 24, and the rotation direction of the auxiliary rollers 23 is parallel to the rotation direction of the roller mounting frame 24. When encountering a step, as the mobile chassis 1 moves forward, the electric telescopic column 22 supports the auxiliary roller 23 on the step, cooperating with the rolling of the step to facilitate the lifting of the track 111 on the front side of the mobile chassis 1, so that the track 111 rolls onto the step.

[0031] In this embodiment, a frame 12 is fixedly installed on the mobile chassis 1, and an mounting frame 13 is mounted on the frame 12. A storage cavity 14 for storage is provided between the frame 12 and the mounting frame 13.

[0032] In this embodiment, a lifting mechanism 3 is provided on the mounting frame 13. The lifting mechanism 3 can serve as a carrier and can also be used to send workers to higher places to facilitate the pruning, daily observation and maintenance of fruit trees, as well as pollination, harvesting or thinning of fruit.

[0033] Specifically, the lifting mechanism 3 is a scissor lift mechanism 31, including a lifting plate 311, a drive telescopic rod 312, and a scissor hinge frame 313. The scissor hinge frames 313 are symmetrically arranged in the vertical direction, and two scissor hinge frames 313 are connected by a connecting plate 314. The upper and lower ends of the scissor hinge frames 313 are connected to the lifting plate 311 and the mounting frame 13 respectively through second hinge seats 315. The drive telescopic rod 312 is a hydraulic rod, which is hinged to the connecting plate 314 and the mounting frame 13 respectively through a third hinge seat 316. When the hydraulic rod extends or shortens, it can drive the scissor hinge frame 313 to extend or compress, thereby raising or lowering the upper lifting plate 311. By using the scissor lift mechanism 31, the lifting height can be increased, and the overall volume of the work vehicle can be reduced during retrieval, resulting in a low space occupancy rate and better adaptability to complex working environments.

[0034] In this embodiment, the lifting plate 311 is also provided with a tipping mechanism 4. The tipping mechanism 4 includes a tilting plate 41, a hinge seat 42 and a drive unit 43. The tilting plate 41 can be used to carry people and goods. When the goods need to be transported to a high place, the tipping mechanism 4 can be used to unload the heavy objects, reducing the labor intensity of workers.

[0035] Specifically, the flip plate 41 is placed against the upper side of the lifting plate 311 and is rotatably connected to the lifting plate 311 via a hinge seat 42 located at one end of the lifting plate 311. The drive unit 43 includes a mounting platform 431, a motor 432, a rack 433, a rolling wheel 434, and a drive roller 435. The mounting platform 431 is fixedly installed at the end of the lifting plate 311 away from the hinge seat 42 and is located below the lifting plate 311. The mounting platform 431 has a clearance groove 4311 and a mounting groove 4312 that passes through the clearance groove 4311. The rack 433 is vertically installed in the mounting groove 4312 via a linear slide rail module 436. The rolling wheel 434 is rotatably installed on the upper end of the rack 433 via a mounting seat 4341 and is in rolling contact with the lower side of the flip plate 41. The drive roller 435 is rotatably mounted on the mounting platform 431 via the bracket 4351. The drive roller 435 has teeth that mesh with the rack 433. The motor 432 is fixedly mounted on the mounting platform 431. One end of the drive roller 435 and the output end of the motor 432 mesh with each other via gears.

[0036] The motor 432 drives the drive roller 435 to rotate, thereby causing the rack 433 meshing with the drive roller 435 to move. During the upward movement of the rack 433, the rolling wheel 434 lifts the tilting plate 41 upward. Due to the action of the hinge seat 42, the tilting plate 41 rotates around the hinge seat 42, thereby tilting the tilting plate 41 to facilitate the unloading of heavy objects. To ensure personnel safety, a guardrail 411 can be installed on the upper side of the tilting plate 41.

[0037] Specifically, the slider of the linear slide rail module 436 is fixedly installed in the mounting groove 4312, and the slide rail of the linear slide rail module 436 is fixedly installed on the rack 433 and is arranged parallel to each other along the length direction.

[0038] In this embodiment, the frame 12 is rectangular, and the vehicle stability mechanism 5 is located at the four corners of the frame 12, on the outside of the mobile chassis 1. The vehicle stability mechanism 5 includes hydraulic rods 51 and support feet 52. The hydraulic rods 51 are vertically mounted on the frame 12 with their actuating ends facing downwards, and the support feet 52 are fixedly mounted on the top of the actuating end of the hydraulic rods 51. By setting the hydraulic rods 51 and support feet 52 at the four corners, the independently operating hydraulic rods 51 can extend to different lengths, ensuring the levelness of the entire vehicle body during operation in sloping ground conditions, thus improving safety.

[0039] Specifically, a control box 15 is also installed on the frame 12, and the control box 15 is electrically connected to the various electrical components of this utility model. The internal electrical control system 151 can improve the intelligence level of this utility model.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
