[0034] The compaction roller 61 is hinged to the vehicle frame 1 through the support rods 64 on both sides, and the height of the compaction roller 61 can be freely adjusted by the lifter 62; when the vehicle is in operation, the compaction roller 61 is in the working position and is in contact with the ground; when the vehicle is not in operation, the compaction roller 61 is raised by operating the lifter 62, and the compaction roller 61 is separated from the ground. At this time, the compaction roller 61 can be prevented from being obstructed by ground gravel, thereby ensuring the stability of the vehicle when moving in the non-working state; and the lifter 62 adopts a telescopic screw 622 in conjunction with a handle 624. It is only necessary to manually turn the handle 624 to control the extension or contraction of the telescopic screw 622, thereby driving the compaction roller 61 to adjust its height, which is simple to operate.

[0035] Belt drives are provided on both sides of the compaction roller 61, between the rotating shaft and the drive rod 65. The belt drives are located outside the support rod 64.

[0037] The function of the contact switch 72 is that when the filler transported by the material taking device 4 is higher than the shaping plate 51, the filler tilts toward the block seat 52. When the filler pushes the opening and closing door of the block seat 52 to trigger the contact switch 72, the contact switch 72 feeds back a signal to the controller 71. The controller 71 controls the vehicle to move forward and drives the compacting roller 61 to compact the filler.

[0038] The present invention adopts a hydraulic system to control the mobile chassis 2 and the material-removing device 4. By controlling the first hydraulic motor and the second hydraulic motor, the vehicle can be operated to move forward and backward, and the differential speed between the crawler wheels on both sides can be used to operate the vehicle steering; by controlling the third hydraulic motor 45, the working speed of the hollow spiral blade 43 can be operated, thereby controlling the material-removing speed of the material-removing device 4; since a belt drive is provided between the compacting roller 61 in the compacting device 6 and the crawler wheel on one side of the mobile chassis 2, the compacting roller 61 can be driven to rotate during the operation of the corresponding crawler wheel.

[0039] The present invention is also designed with a remote controller 73, which can use manual remote control technology to operate the vehicle, making it easier for personnel to operate the vehicle while also avoiding operational risks for personnel.

[0040] The specific usage and function of this embodiment are as follows:

[0041] First, the vehicle must be in the working position. At this time, the feeding plate 42 should be inserted into the cargo stack, and the compacting roller 61 should touch the ground. Then, the third hydraulic motor 45 is started to control the operation of the hollow spiral blade 43. The hollow spiral blade 43 transports the ore falling into the feeding plate 42 through the stirring cage 41 and transports it from the feeding port 411 to the shaping plate 51 as filler. The filler is initially shaped in the shaping plate 51. When the filler accumulates to a height exceeding the shaping plate 51, the filler tilts toward the block seat 52, and the filler pushes the opening and closing door of the block seat 52 until the opening and closing door triggers the contact switch 72, and the contact switch 72 feeds back a signal to the controller 71. , the controller 71 sends a signal to the first hydraulic motor and the second hydraulic motor to start the vehicle to move forward. During the process of the vehicle moving forward, the compacting roller 61 is driven by the mobile chassis 2 and will also rotate at the same time. The compacting roller 61 rotates and moves to compact and fix the filler; during the process of the vehicle moving forward, the filler higher than the shaping plate 51 is pushed to the ground. At this time, the opening and closing door of the block seat 52 loses the squeezing force and resets. After resetting, the vehicle stops moving forward. Later, when the opening and closing door is pressurized again to trigger the contact switch 72, the vehicle continues to move forward to compact the filler. This action is repeated and the cargo stack cofferdam operation can be completed after completing the entire process.

[0042] Among them, if the material picking plate 42 cannot be inserted into the cargo stack due to lack of materials, and the material cannot be picked up, the operator manually disassembles and reinstalls the installation position of the material picking plate 42 on the mixing cage 41, adjusts the protruding length of the material picking plate 42 at one end of the mixing cage 41, and manually operates the bolt 442 to change the position of the bolt 442 on the travel groove of the lifting plate 441, and then adjusts the protruding angle of the mixing cage 41. Through the above two adjustment schemes and their combination, the material picking plate 42 is adjusted to the position of extending into the cargo stack, and the material picking operation can continue.

[0043] When the vehicle is moving forward, the operator can remotely adjust the flow of the first hydraulic motor and the second hydraulic motor, and use the difference between the tracked wheels on both sides of the mobile chassis 2 to change the vehicle's forward angle, thereby achieving the purpose of vehicle route correction and vehicle steering.

[0044] In summary, the present invention designs a ridging and cofferdam vehicle that can be remotely controlled by humans. Compared with traditional manual operations, it liberates human resources, improves work efficiency, and effectively solves the problems of high work intensity and low work efficiency of traditional solutions.
