Description

Technical Field

[0001] The present invention relates to the field of special vehicles, and particularly to an obstacle-breaking earth-moving off-road vehicle. Background Art

[0002] In engineering practice, the following problems exist: Firstly, the existing obstacle-breaking bulldozers are often thick, heavy and slow in movement. For example, CN215630250U discloses an obstacle-breaking bulldozing shovel, where the fixed end of the shovel deformation cylinder is hinged inside the shovel support, and the movable end of the shovel deformation cylinder is hinged to one end of the corresponding shovel pull rod. The other end of one shovel pull rod penetrates through the corresponding pull rod positioning rod and is hinged to the first shovel, and the other end of the other shovel pull rod penetrates through the corresponding pull rod positioning rod and is hinged to the second shovel. The pull rod positioning rod is rotatably installed on the shovel support, and both the first shovel and the second shovel are hinged to the shovel support 5. Thus, the first shovel and the second shovel can be switched between the "one" shape and the "eight" shape, and the shoveling state can be automatically switched after obstacle breaking. Such an obstacle-breaking bulldozing shovel is generally applied to the bulldozers on construction sites. The bulldozers move slowly, and the conversion structure between the "one" shape and the "eight" shape is complex and heavy.

[0003] In many cases in the non-construction field of actual projects, such as when special vehicles perform tasks, the requirements for moving speed and obstacle-breaking function are much greater than the shoveling function. It can only break obstacles without clearing soil or temporarily not clearing soil, and its daily normal state is only the obstacle-breaking form, and it switches to the shoveling form in a few cases. At this time, the defects of the existing technology such as CN215630250U, which are slow in movement, complex in structure and heavy, cannot meet the work needs.

[0004] Secondly, for the existing obstacle-breaking components or bulldozing shovels, they use a driving cylinder for flipping actions. However, the end of the driving rod of the driving cylinder cannot be well supported near the centroid of the obstacle-breaking component or bulldozing shovel, so that the flipping driving force cannot be evenly transmitted, resulting in uneven or unstable force transmission.

[0005] Thirdly, the driving rods of the existing obstacle-breaking components or bulldozing shovels cannot be freely combined and lack flexibility. Summary of the Invention

[0006] In order to overcome the above problems, the present invention proposes a solution to simultaneously solve the above multiple problems.

[0007] The technical solution adopted by the present invention to solve its technical problems is: an obstacle-breaking earth-moving off-road vehicle, including a vehicle head, a chassis, wheels, a housing, an execution mechanism, a bumper, and a communication module. The chassis is arranged below the vehicle head, the wheels are arranged below the chassis, the housing is connected behind the vehicle head, the communication module is arranged above the housing, the execution mechanism and the bumper are arranged in front of the vehicle head. A spare tire is arranged inside the housing, and a top cover is arranged above the vehicle head. The actuator includes a first arm, a second arm, a third arm, a tipping cylinder, a first crossbar, a second crossbar, a right plate, a left plate, an L-shaped plate, a pivot seat, and a hinge seat; each of the left plate and the right plate is provided with 18 grooves, which are arranged in three rows and six columns. The three rows are the upper, middle, and lower rows, and partitions are provided between the grooves; the left plate and the right plate can be disassembled, spliced, and swapped left and right positions; several of the 18 grooves are internally provided with the same pivot seats, and one pivot seat is provided in each of the second and fifth cells in the lower row. One end of the first arm is connected to the chassis, and the other end forms a size contraction part, which is connected to a pivot seat in the lower row. The hinge seat is connected to the bumper. The hinge seat is provided with upper and lower hinge points. The upper hinge point is connected to one end of the tipping cylinder, and the other end of the tipping cylinder is connected to the adjusting part through a connecting shaft. The lower hinge point is connected to one end of the second arm, and the other end of the second arm is connected to a hinge seat in the middle row. The adjusting part is formed by protruding a certain height on the second arm, and the protruding height of the adjusting part is greater than five times the diameter of the connecting shaft. One end of the third arm is connected to another pivot seat in the lower row, and the other end is connected to the first arm; one first arm, one second arm, one third arm, and one tipping cylinder are respectively provided corresponding to the left plate and the right plate; a first crossbar is provided between the two first arms, and a second crossbar is provided between the two second arms; L-shaped plates are detachably connected to the left plate and the right plate respectively, and holes are provided on the first arm, the second arm, and the third arm.

[0008] Preferably, the diameters of the holes on the first arm, the second arm, and the third arm are different.

[0009] Preferably, the diameters of the holes on the first arm, the second arm, and the third arm are the same.

[0010] Preferably, the first arm and the third arm are connected by a shaft.

[0011] Preferably, both ends of the shaft include connecting parts with different diameters.

[0012] Preferably, the other end of the third arm is connected to the first arm by welding.

[0013] Preferably, each of the left plate and the right plate includes a left wall and a right wall, and the left wall and the right wall participate in enclosing the groove.

[0014] Preferably, threaded holes are provided on both the left wall and the right wall.

[0015] Preferably, a door is provided on the vehicle head, and a rearview mirror is provided on the door.

[0016] Preferably, a handle bar is also provided on the vehicle head.

[0017] The beneficial effects of the present invention are: For the first problem raised in the background art, the following solutions are adopted: Inventive point 1: The obstacle-breaking component or the bulldozer blade is divided into two independent half plates, and the two half plates can be quickly disassembled and assembled through different splicing methods to form a spread or inverted spread respectively, so as to serve as the obstacle-breaking component or the bulldozer blade in different states. In normal times, it is in the obstacle-breaking form, and in a few cases, it can be quickly disassembled and assembled to form a soil-shoveling form.

[0018] In addition, a flange is provided below the common bulldozer blade for facilitating soil shoveling; due to the splicing structure of the present invention, the flange is not required in the obstacle-breaking form, so a detachable L-shaped plate that functions as a flange is provided, and it can be selected whether to install the L-shaped plate according to needs.

[0019] Inventive point 2: As mentioned above, the common methods for quick disassembly and assembly by splicing include mortise and tenon joints, but they are not firm. It also includes connections such as screws and bolts. However, this requires drilling many holes in thick steel plates and iron plates, with high processing difficulty, and there is difficulty in splicing along the length direction.

[0020] Inventive point 2 makes a design for this. Three rows and six columns of grooves are opened on both half plates, divided into upper, middle, and lower rows, and the six columns of grooves extend vertically, so that 18 grids are formed on each of the two half plates. Since each grid has corresponding several partitions, and the frame walls of the corresponding half plates also serve as partitions, when connecting the two half plates, only the partitions need to be connected with screws and bolts.

[0021] Although the setting of the grids reduces the strength of the steel plate, it should be emphasized that the present invention is not used for soil shoveling in construction sites, but for off-road vehicles. The setting of the grids instead reduces the weight of the steel plate, making it more conducive to the moving speed of off-road vehicles.

[0022] Inventive point 3: As mentioned above, such a connection is still not stable enough and has insufficient load-bearing capacity. Therefore, 18 grids are also used to embed some identical pivot seats, and these pivot seats are connected to many rods or arms. Through these rods or arms, the weight of the half plate can be borne, so that the above-mentioned screw and bolt connections only play a docking role and do not need to bear great forces.

[0023] At the same time, considering the different splicing methods of spread or inverted spread between the half plates, the positions of the pivot seats are symmetrical in each half plate. For example, the same pivot seats are respectively arranged in the grids of the 2nd and 5th columns in the lower row, so that when the left and right half plates are interchanged, there is no need to disassemble and adjust the positions of the pivot seats. This is a preferred solution, and it can be selected according to needs. The connection structures of components such as screws, bolts, pivot seats, rods, and arms are all convenient for disassembly and assembly.

[0024] For the second problem raised in the background art, the following solutions are adopted: Fourth inventive point: Connect the actuator end of the tipping cylinder to the adjustment part to adjust the connection position of the actuator end downward. The adjustment part is integrally connected to an arm, and the arm is connected near the center of mass of the obstacle-breaking component or the bulldozing blade. Since the adjustment part and the arm are intermediate components connecting the cylinder to the obstacle-breaking component or the bulldozing blade, the tipping force application point is closer to the center of mass of the obstacle-breaking component or the bulldozing blade, thus achieving a smoother tipping motion.

[0025] For the third problem proposed in the background art, the following solution is adopted: Fifth inventive point: Drill holes in each arm and rod. These holes can be the same or different to adapt to different arm sizes. However, the holes for connecting the arm to the pivot seat are the same, and a diameter-reducing part can be provided at the end of the boom to adapt to the small holes. The other drilled holes can be quickly connected through a connecting rod with different diameters at both ends, so as to combine the arms and thus adjust the strength and load-bearing capacity of the overall arm structure. Of course, if a certain state is always used without replacement, the arms can also be fixedly welded, and the specific choice depends on the requirements. BRIEF DESCRIPTION OF THE DRAWINGS
