[0033] Reference Figure 1-Figure 4The first spring 5 is connected to the first spring 5 at the bottom of the load-bearing plate 4, and the other end of the first spring 5 is connected to the top of the fixed plate 3. The top of the load-bearing plate 4 contacts the bottom of the cargo box 1. The positioning plate 6 is installed on both sides of the top of the shock-absorbing plate 2. A movable plate 7 is installed on the outer side of the positioning plate 6. The top of the shock-absorbing plate 2 is fixedly connected with a reinforcement seat 8 located on the inner side of the positioning plate 6. The second spring 9 is installed on the outer side of the positioning plate 6. The other end of the second spring 9 is connected to the inner side of the movable plate 7.

The shock-absorbing linkage mechanism is fixedly connected to the inner side of the load-bearing plate 4. When the cargo box 1 is working, the load-bearing plate 4 is affected by the vibration force of the cargo box 1 and exerts a downward thrust on the first spring 5, so that the first spring 5 cooperates with the fixed plate 3 and the shock-absorbing plate 2 to perform The movable plate 7 is subjected to the lateral shock absorption work, and at the same time, the movable plate 7 is affected by the downward thrust of the force plate 4 to push the second spring 9 to move and cooperate with the positioning plate 6 to perform lateral shock absorption on the cargo box 1. The device is stabilized by the lateral and longitudinal linkage shock absorption to dampen the cargo box 1. The shock absorption linkage mechanism includes a fixed seat 11, a linkage rod 12 and a movable seat 13.

[0034] Reference Figure 2-Figure 3 The bottom of the movable plate 7 is fixedly connected with a sliding seat 15 which is slidably connected to the damping plate 2, so that the positioning plate 6 and the damping plate 2 can be fixedly connected during the operation of the positioning plate 6. At the same time, the movable plate 7 and the damping plate 2 can be movably supported to avoid the position displacement of the positioning plate 6 and the movable plate 7 during the operation, thereby improving the working stability of the movable plate 7 and the positioning plate 6.

[0035] Reference Figure 2-Figure 3 In a preferred embodiment, a slag opening 18 is provided at the bottom of the inner wall of the limiting groove 16, and a plurality of slag openings 18 are provided, and the plurality of slag openings 18 are distributed at equal distances. In the process of the limiting groove 16 cooperating with the limiting seat 17 and the sliding plate working, a slag removal space can be provided for the limiting groove 16, so as to prevent external slag and dirt from entering the limiting groove 16, resulting in obstruction of the working of the limiting seat 17, thereby improving the working stability of the limiting seat 17.

In the working process of the shock-absorbing plate 2, the shock-absorbing plate 2 can be subjected to shock-absorbing auxiliary work. At the same time, a space for discharging slag blocks is provided for the slag opening 18, so as to prevent slag blocks from entering the slag opening 18 and being difficult to discharge, thereby improving the working effect of the shock-absorbing plate 2 and the slag opening 18.

[0036] Reference Figure 2-Figure 3 In a preferred embodiment, mounting holes 21 are provided on the front and rear sides of both sides of the top of the shock-absorbing plate 2 and the shock-absorbing pad 19, and mounting bolts 22 are installed inside the mounting holes 21. The bottom of the mounting bolts 22 penetrates to the bottom of the shock-absorbing pad 19. During the operation of the shock-absorbing plate 2 in cooperation with the cargo box 1, a medium for connecting the shock-absorbing plate 2 with the external frame can be provided for the user, thereby avoiding the situation that the shock-absorbing plate 2 is difficult to install and connect when in use, thereby improving the convenience of installation and connection of the shock-absorbing plate 2. A second damper 23 is fixedly connected to the top of the fixed plate 3, and the second damper 23 is located on the inner side of the first spring 5. The movable end of the second damper 23 is connected to the bottom of the force-bearing plate 4. During the operation of the force-bearing plate 4 and the fixed plate 3 in cooperation with the first spring 5, the vibration force received by the first spring 5 can be absorbed and dissipated through the damping mechanism, thereby reducing the vibration capacity of the first spring 5 during operation, thereby avoiding the situation that the vibration force absorption and dissipation effect is insufficient during operation of the first spring 5, thereby improving the shock-absorbing effect of the first spring 5.

[0037] Specifically, the working process or working principle of the shock-absorbing device for the cargo box of a dump truck is as follows: when in use, the shock-absorbing plate 2 and the shock-absorbing pad 19 are installed on the top of the external frame chassis through the mounting hole 21 and the mounting bolt 22, so that the top of the force-bearing plate 4 contacts the bottom of the cargo box 1. When the cargo box 1 is bumped and vibrated during operation, the force-bearing plate 4 moves downward by the vibration force of the cargo box 1, pushing the first spring 5 to contract, and performing preliminary absorption and dissipation work on the vibration force of the cargo box 1. At the same time, the second damper 23 further absorbs and dissipates the vibration force during the contraction process of the first spring 5. During this process, the fixed seat 11 moves downward with the force-bearing plate 4 to apply a thrust to the linkage rod 12. The linkage rod 12 that is subjected to the downward force applies a thrust to the movable plate 7 through the movable seat 13, so that the movable plate 7 pushes the second spring 9 to contract, and the vibration force received by the force-bearing plate 4 during operation is dispersed, absorbed and dissipated. At the same time, the first damper 10 absorbs and dissipates the vibration force received by the second spring 9 during operation. The vibration force during the contraction of the spring 9 is further absorbed and dissipated, and the cargo box 1 as a whole is subjected to dual force and shock absorption in the horizontal and vertical directions. At the same time, the sliding seat 15 follows the movable plate 7 to drive the limiting seat 17 to move inside the limiting groove 16, and performs sliding limiting work between the movable plate 7 and the shock absorbing plate 2. At the same time, as the limiting seat 17 slides inside the limiting groove 16, the slag block inside the limiting groove 16 is affected by the left and right moving force of the limiting seat 17 to enter the slag opening 18. At this time, the slag opening 18 entering the slag opening 18 falls into the discharge port 20 and is discharged through the discharge port 20. In the process of the positioning plate 6 cooperating with the second spring 9 and the first damper 10, the connecting seat 14 cooperates with the reinforcing seat 8 to reinforce and stabilize the space between the positioning plate 6 and the shock absorbing plate 2, so that the positioning plate 6 cooperates with the second spring 9 and the first damper 10 to perform stable shock absorption work on the cargo box 1, thereby ensuring the stability of the cargo box 1 during operation.

[0038] It should be noted that the first damper 10 and the second damper 23 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
