Technical Field

[0001] The utility model relates to the technical field of machine-made sand transportation, in particular to a machine-made sand transportation device. Background Art

[0002] Artificial sand refers to sand processed by sand making machines and other ancillary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. Artificial sand requires professional equipment to produce qualified and applicable sand and gravel. At the same time, artificial sand usually requires transportation equipment for transportation on the construction site, usually by sand carts.

[0003] When the machine-made sand transport device on the market is actually used, if an emergency occurs when the user encounters an uphill situation, the machine-made sand transport device cannot be limited immediately without help, which will cause safety hazards, and the machine-made sand transport device needs to be improved.

[0006] The limiting structure includes a partition, a limit plate, an electric telescopic rod, a sliding block, a limit plate, a limit block, a fixed plate, a fixed frame, a return spring, a limit block, a limit pad, a movable rod and a limit partition. The fixed plate is fixedly connected to the outside of the sand transport cart, the fixed frame is fixedly connected to the fixed plate, the movable rod passes through the fixed plate and the fixed frame, the limit block is fixedly connected to the lower end of the movable rod, the limit pad is fixedly connected to the lower end of the limit block, the limit partition is fixedly connected to the inner wall of the fixed frame, the return spring is sleeved on the outside of the movable rod, the partition is fixedly connected to the inner wall of the sand transport cart, the limit plate is fixedly connected between the partition and the sand transport cart, the electric telescopic rod is fixedly connected to the side of the limit plate, the output end direction of the electric telescopic rod is on the left side, the limit plate is fixedly connected to the output end of the electric telescopic rod, the movable rod is fixedly connected to the lower end of the limit plate, the movable rod slides in the sand transport cart, and the limit block is fixedly connected to the upper end of the movable rod.

[0007] Furthermore, a sliding groove is provided in the sand transport cart, and the sliding block slides in the sand transport cart through the sliding groove.

[0008] Furthermore, the right side of the sand transport cart is rotatably connected to a front roller, and the left side of the sand transport cart is rotatably connected to a rear roller.

[0009] Among them, the specifications of the front roller are larger than those of the rear roller.

[0010] Furthermore, one end of the return spring is fixedly connected to the fixed plate, and the other end of the return spring is fixedly connected to the limiting partition.

[0011] Among them, a rubber pad is fixedly connected to the left side of the fixing plate, and the rubber pad can play a role in protecting the structure when the cleaning plate 11 is bent, thereby enhancing the service life of the cleaning structure.

[0014] There are several cleaning blocks, and the cleaning blocks are triangular in shape, which can facilitate cleaning of mud and sand on the soles.

[0015] It should be noted that the outer side of the cleaning block is coated with a nano coating.

[0016] It is understandable that the nano coating is prepared using nanotechnology and can effectively prevent the erosion of the surface of objects by granular materials such as mud and sand. This coating usually has a high density and hydrophobicity, and can form a hard barrier that makes it difficult for particles such as mud and sand to adhere to the surface of objects, thereby achieving the effect of cleaning the mud and sand on the soles while facilitating the cleaning of the cleaning plate.

[0017] Furthermore, a limiting hole is provided on the side of the sand transport cart, and the cleaning plate and the limiting plate both pass through the limiting hole to penetrate the sand transport cart.

[0019] The machine-made sand transport device has the function that the user can push the sand transport cart for displacement and transportation by means of the handle in cooperation with the front rollers and the rear rollers. The limiting structure arranged on the sand transport cart can not only limit the position of the sand transport cart on a plane, but also perform emergency braking on the sand transport cart when the user encounters an emergency while going uphill, thereby protecting the safety of the workers. The design of the cleaning plate and the cleaning block can assist the patient in cleaning and removing the mud and sand on the soles of the feet, thereby enhancing the practicality of the machine-made sand transport device and other advantages.
