Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0024] Embodiment
[0025] Please refer to Figures 1-6, the present utility model provides a technical solution: a sand and gravel handling device for construction engineering, including a vehicle-mounted frame 1 and moving wheels 2.

Through the moving wheels 2, the device can be moved to the construction site where sand and gravel are stored. By controlling the mutual cooperation of the lateral moving mechanism, the vertical moving mechanism and the longitudinal moving mechanism, the opening and closing grasping mechanism can be positioned at the sand and gravel. Before positioning, since the side rotating rods 8 are rotatably arranged with the base 6 and the side rotating rods 8 are rotatably arranged with the opening and closing grab assembly 9, when the intermediate hydraulic cylinder 7 moves downward, the side rotating rods 8 will rotate, causing the opening and closing grab assembly 9 to rotate relatively, so that the opening of the opening and closing grab assembly 9 faces downward. Then it is positioned at the sand and gravel. When the intermediate hydraulic cylinder 7 moves upward, the side rotating rods 8 will rotate, causing the opening and closing grab assembly 9 to rotate relatively, so that the ports of the opening and closing grab assembly 9 are relatively close to form a closed grasping. After grasping, control the mutual cooperation of the lateral moving mechanism, the vertical moving mechanism and the longitudinal moving mechanism to make the opening and closing grab assembly 9 above the sand and gravel storage box 13. Secondly, when controlling the intermediate hydraulic cylinder 7 to move downward, the side rotating rods 8 will rotate, causing the opening and closing grab assembly 9 to rotate relatively, so that the opening of the opening and closing grab assembly is downward, enabling the sand and gravel to automatically fall into the sand and gravel storage box 13. This process has the function of automatically grasping and storing sand and gravel, greatly reducing the labor intensity of workers, without the need to use shovels for operation, and the operation is simple; according to the position of the sand and gravel required for on-site construction, move to the required position through the moving wheels 2, then pull out the plug-in plate 14, and then drive the push plate 15 to move to one side by the driving cylinder 16 to push and unload the sand and gravel in the sand and gravel storage box 13.
