Description

Technical Field

[0001] The present invention relates to the technical field of agricultural transportation equipment, and more specifically, to a spatial link mechanism profiling track electric drive walking - hydraulic operation dual - power platform. Background Art

[0002] The development of agricultural planting is closely related to the level of agricultural mechanization. Currently, hilly orchard management machinery faces multi - dimensional technical bottlenecks such as terrain adaptation, power matching, function integration, and ecological compatibility. Traditional operation machinery is mostly developed for plain terrain, and significant defects are exposed when applied in hilly landscapes: In terms of terrain adaptability, existing wheeled machinery generally has the risks of power loss and side - slip overturn on slopes above 15°. Although the use of a crawler structure can improve passability, its turning radius is too large (>3m), resulting in an increase in the fruit tree collision damage rate of more than 28%. Moreover, the response delay of the traditional suspension system to uneven terrain (height difference >30cm) causes the ground pressure of the operation device to fluctuate by more than 40%, seriously affecting the fertilization uniformity and mowing coverage rate. The problem of unbalanced power system matching is prominent. The fuel efficiency of general diesel engines decays by 35 - 45% under frequent start - stop conditions in hilly areas, and the exhaust emissions also pose a threat to the orchard ecological environment. At the same time, the single - power output design leads to power competition between the walking and operation systems, and the measured effective power utilization rate during ramp operation is less than 60%. At the level of functional integration, the fixed - welding structure makes the equipment function conversion time exceed 45 minutes per time, making it difficult to meet the rapid switching requirements of multiple tasks such as spraying, transportation, and pruning. In addition, the short - board of ecological compatibility is significant. The ground contact pressure of traditional large - scale machinery is higher than 80 kPa, and long - term operation causes the soil bulk density at a depth of 20 cm to increase by 12 - 15%, inhibiting the root development of fruit trees. Therefore, it is necessary to start from the actual situation of hilly and mountainous areas, analyze the topography and geomorphology of hilly and mountainous areas, and design agricultural machinery suitable for hilly and mountainous areas according to local conditions, so as to improve the overall level of agricultural mechanization and give play to the potential of the region. Hilly and mountainous areas usually have large slopes and uneven terrains, which makes it difficult for traditional agricultural machinery to adapt. Moreover, the roads in hilly and mountainous areas are narrow and irregularly distributed, making it difficult for traditional agricultural machinery to work properly under such conditions. The agricultural equipment has difficulty in traveling and a low passing rate. In terms of agricultural operations, a series of tasks such as ditch - digging, weeding, and spraying are often required. The working environment is harsh and there are certain requirements for the endurance of agricultural machinery, which all hinder the development of the mechanization level in hilly and mountainous areas. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a spatial link mechanism profiling track electric drive walking - hydraulic operation dual - power platform in view of the above - mentioned deficiencies.

[0004] To solve the above - mentioned technical problems, the present invention adopts the following technical solutions:

[0005] A spatial linkage profiling crawler electric walking - hydraulic operation dual - power platform, comprising an electric crawler chassis, a gasoline engine, a double - gear pump, hydraulic equipment, a lithium battery, and a lifting and mounting mechanism. The electric crawler chassis includes a crawler walking system, a spatial linkage profiling mechanism, and a frame. The frame is horizontally arranged. The gasoline engine, the double - gear pump, the hydraulic equipment, the lithium battery, and the lifting and mounting mechanism are all arranged on the frame. The lithium battery is used to provide power for the crawler walking system. The lifting and mounting mechanism is used to mount external tools. The gasoline engine is used to drive the double - gear pump through a pulley to provide a power source for the hydraulic equipment. The hydraulic equipment is used to provide a power source for external tools. The spatial linkage mechanism includes a load - bearing plate arranged at the rear of the frame and crawler frames symmetrically arranged on the left and right sides of the rear load - bearing plate. A crawler walking mechanism is arranged on the outer side of the crawler frames. The middle of the load - bearing plate is arranged behind the rear of the frame through a rotating shaft. Both ends of the load - bearing plate are hinged to one end of the two - side crawler frames through vertically arranged connecting rods. The other ends of the two - side crawler frames are hinged to the left and right sides of the frame through bearing seats. When one - side crawler walking mechanism bumps and moves on an uneven road surface and rotates around the load - bearing plate, it will drive the other - side crawler walking mechanism to rotate in the opposite direction by the same angle around the hinge point on that side through the connecting rod and the load - bearing plate to achieve the profiling function.

[0006] Further, the crawler walking mechanism includes a driving motor, a worm - gear and worm - wheel reducer, a driving wheel, a supporting roller, a vertical bearing seat, a carrying roller, a tensioning wheel, a crawler frame, a limiting square steel, a connecting shaft, and a rubber crawler, wherein the connecting shaft is fixed on the limiting square steel and welded to the crawler frame.

[0007] Further, the other ends of the two - side crawler frames are hinged to the left and right sides of a smooth shaft horizontally arranged on the frame through bearing seats.

[0008] After the present invention adopts the above - mentioned technical solutions, compared with the prior art, it has the following advantages:

[0009] Compared with the current traditional - power chassis, the spatial linkage profiling crawler electric walking - hydraulic operation dual - power platform of the present invention can make the walking mechanisms on the left and right sides alternately move up and down following the uneven ground to simulate the walking effect, so as to achieve the profiling function, enabling the power platform to better fit the complex ground shape, improving the crawler grounding effect, enhancing the walking ability, and having the advantages of strong terrain adaptability, strong passability, and simple operation. The smaller volume and the crawler chassis improve the passability of the power platform in hilly and mountainous areas. The spatial linkage profiling mechanism enables the crawler chassis to adapt to more rugged terrains. The electric crawler chassis simplifies the operation process. The present invention adopts a crawler - type chassis, with a low overall center of gravity and strong passability. The power configuration of the walking system driven by electricity and the working system driven by hydraulics makes full use of the advantages of easy control of electric driving, the cost advantage of small - capacity batteries, and the high - load and low - cost advantage of hydraulics, while reducing the operation cost and simplifying the operation to ensure the operation quality.
