[0020] The materials of the construction project are carried by the cart box 1, and the cart box 1 is moved under the action of the roller 5 by pushing the handrail rod 6. When unloading is required, the handrail rod 6 can be pushed upward with the shaft rod 4 as the center of the circle to pour the materials out of the cart box 1. When there are residual materials in the cart box 1 that cannot be poured out, the door panel 2 is opened by opening the limit assembly, and the pushing assembly drives the push plate 7 to push the materials in the cart box 1 out of the cart box 1, so that the materials are completely poured out of the cart box 1. The shock-absorbing support rod assembly plays a shock-absorbing and supporting role on the cart box 1 to prevent the cart box 1 from vibrating when it is placed on the ground for a moment.

[0023] This embodiment is further configured such that the lower end of the vertical end of the L-shaped plug rod 10 is provided with an external thread, and the L-shaped plug rod 10 is screwed with a limit nut 11 through the external thread;

[0026] The lead screw 15 is rotated and meshed with the push rod 18 through a threaded groove, so that the lead screw 15 has a guiding effect on the push rod 18 when it rotates. At this time, the push rod 18 moves along the path of the slide groove 16 under the action of the slider 17, so that the push rod 18 pushes the push plate 7. The push plate 7 moves under the action of the guide rod 12, and the limit plate 13 prevents the guide rod 12 from moving out of the handrail rod 6.

[0027] This embodiment is further configured such that a reinforcing rib 19 is fixedly installed between the cylinder 14 and the handrail rod 6 , and the other end of the lead screw 15 is exposed outside the cylinder 14 and a handle 20 is fixedly installed thereon.

[0029] After releasing the handrail rod 6, the rear end of the cart box 1 moves downward, and the cart box 1 pushes the support column 21, and the support column 21 pushes the piston plate 23 and then squeezes the first spring 24. The first spring 24 absorbs the pressure and plays a shock absorbing role. At the same time, the second spring 25 is compressed by force, and the second spring 25 absorbs the pressure and plays a shock absorbing role. In order to prevent the first spring 24 and the second spring 25 from rebounding back and forth, damping oil is filled in the support cylinder 22, and an oil hole is opened on the piston plate 23. When the piston plate 23 moves downward, the damping oil moves from one side of the piston plate 23 to the other side through the oil hole. Since the damping oil is relatively viscous, the piston plate 23 moves slowly, thereby preventing the first spring 24 and the second spring 25 from rebounding back and forth, thereby playing a damping role.

[0030] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0031] Embodiment: According to the attached drawings of the specification, the materials of the construction project are carried by the cart box 1, and the cart box 1 is moved under the action of the roller 5 by pushing the handrail 6. When unloading is required, the handrail 6 can be pushed upward with the shaft 4 as the center of the circle to pour the materials out of the cart box 1. When there are residual materials in the cart box 1 that cannot be poured out, the limit nut 11 is rotated to make the limit nut 11 move out from the L-shaped plug rod 10, and the L-shaped plug rod 10 is pulled upward to make the L-shaped plug rod 10 move out from the first through hole and the second through hole. At this time, the door panel 2 drives the plug rod 10 to move out of the first through hole and the second through hole. The plate 8 is moved out of the carrying ring 9, and the door plate 2 is opened from the cart box 1, and the lead screw 15 is rotated. The lead screw 15 is meshed and connected with the push rod 18 through a threaded groove, so that the lead screw 15 has a guiding effect on the push rod 18 when it rotates. At this time, the push rod 18 moves along the path of the slide groove 16 under the action of the slider 17, so that the push rod 18 pushes the push plate 7, and the push plate 7 moves under the action of the guide rod 12. The limit plate 13 prevents the guide rod 12 from moving out of the handrail rod 6, and the push plate 7 pushes the materials in the cart box 1 out of the cart box 1, so that the materials are completely poured out of the cart box 1;

[0032] After releasing the handrail rod 6, the rear end of the cart box 1 moves downward, and the cart box 1 pushes the support column 21, and the support column 21 pushes the piston plate 23 and then squeezes the first spring 24. The first spring 24 absorbs the pressure and plays a shock absorbing role. At the same time, the second spring 25 is compressed by force, and the second spring 25 absorbs the pressure and plays a shock absorbing role. In order to prevent the first spring 24 and the second spring 25 from rebounding back and forth, damping oil is filled in the support cylinder 22, and an oil hole is opened on the piston plate 23. When the piston plate 23 moves downward, the damping oil moves from one side of the piston plate 23 to the other side through the oil hole. Since the damping oil is relatively viscous, the piston plate 23 moves slowly, thereby preventing the first spring 24 and the second spring 25 from rebounding back and forth, thereby playing a damping role.
