[0002] Sand and gravel need to be laid at the bottom of the foundation pit. The specific operations are: 1. The thickness of each layer of sand and gravel is generally 20cm, and the thickness of each layer does not exceed 30cm. The layer thickness is controlled by sample piles; 2. The base surface of the sand and gravel foundation is laid at the same elevation. If the depth is different, the base soil surface is dug into steps or slopes. Pay attention to compaction (tamping) at the joints. The construction is carried out in the order of deep first and shallow later.

[0003] When laying sand and gravel in a foundation pit, the sand and gravel are usually piled up by a wheelbarrow, and then spread evenly by a shovel or the like. In this step, since the sand and gravel are in a piled state, it is slightly inconvenient to use a shovel to evenly lay the material. Therefore, a spreading device for laying a sand and gravel foundation is needed, which can evenly spread the sand and gravel at the bottom of the foundation pit to be laid, avoids raking the sand and gravel flat and evenly laying the material with a shovel when the sand and gravel are piled up, and can effectively reduce the use of shovels, thereby reducing the work intensity when laying sand and gravel.

The button switch 16, the motor 8 and the battery 14 are electrically connected through wires.

[0026] Working principle: When the utility model is used, the user places sand and gravel in the inner cavity of the vehicle compartment 1, and then pushes the vehicle frame 2 to carry the sand and gravel to the destination through the vehicle compartment 1. The setting of the handle 15 increases the friction on the surface of the vehicle frame 2, and avoids the user's hand slipping when holding the vehicle frame 2 directly. Then, the button switch 16 controls the motor 8 to drive the turntable 9 to rotate, so that the turntable 9 swings the tooth plate 11 through the dial shaft 10, and then the tooth plate 11 drives the rack 12 to move, so that the rack 12 drives the blocking plate 5 to slide open through the connecting rod 13, at which time the bottom of the discharge port 3 is exposed, so that the sand and gravel in the inner cavity of the compartment 1 can be evenly discharged to the bottom of the foundation pit through the discharge port 3. In this process, the motor 8 is powered by the battery 14, avoiding the inconvenience of external wiring, and achieving uniform distribution of sand and gravel at the bottom of the foundation pit to be laid, avoiding the need to use a shovel to rake the sand and gravel flat and evenly lay the sand and gravel when they are piled up, which can effectively reduce the use of shovels and thereby reduce the work intensity when laying sand and gravel.

[0027] In summary, the spreading device for laying the sand and gravel foundation drives the turntable 9 to rotate through the motor 8, so that the turntable 9 drives the tooth plate 11 to swing through the dial shaft 10, and then the tooth plate 11 drives the rack 12 to move, so that the rack 12 drives the blocking plate 5 to slide and open through the connecting rod 13, so that the sand and gravel in the inner cavity of the compartment 1 can be discharged to the bottom of the foundation pit through the discharge port 3, so as to achieve the goal of evenly spreading the sand and gravel at the bottom of the foundation pit to be laid, avoiding the need to rake the sand and gravel with a shovel and evenly lay the material when the sand and gravel are piled up, which can effectively reduce the use of shovels and thereby reduce the work intensity when laying sand and gravel.
