[0033] Please refer to Figures 1 to 3 , a sand box provided by an embodiment of the present utility model includes a box body 1, a stirring assembly, and a sand blasting assembly;
[0034] The box body 1 is used to accommodate sand water, the sand blasting assembly is communicated with the box body 1, and the sand blasting assembly is used to extract the sand water in the box body 1 and supply the sand water to a preset position;
[0035] The stirring assembly includes a stirring pump 2, a first pipeline 3, and a plurality of nozzles 15;
[0036] The stirring pump 2 is installed on the box body 1, the extraction end of the stirring pump 2 extends into the box body 1, the extraction end is connected with a first extraction pipe, the first extraction pipe extends from the inside of the box body 1 to the outside of the box body 1 and is communicated with the first pipeline 3, the first pipeline 3 is connected with a plurality of branch pipelines, a plurality of the branch pipelines extend into the box body 1, and each of the branch pipelines is connected with one of the nozzles 15;
[0037] The stirring pump 2 is used to extract the sand water in the box body 1 and transport the sand water to each of the branch pipelines, and the nozzles 15 spray the sand water in the box body 1 to stir the sand water in the box body 1.
[0038] In the sand box of this embodiment, the stirring pump 2 extracts the sand water in the box body 1 and transports the sand water to the nozzles 15 of each branch pipeline. The nozzles 15 spray the sand water in the box body 1 to stir the sand water in the box body 1. Through the above design, the nozzles 15 perform cyclic impact stirring on the sand water in the box body 1, greatly improving the flow of the sand water in the box body 1, thereby avoiding the situation of sand accumulation in the box body 1.
[0039] Further, the inside of the box body 1 of this embodiment has four corners, namely a first corner, a second corner, a third corner, and a fourth corner;
[0040] Two partitions 16 are further arranged inside the box body 1. The two partitions 16 are located at the middle position inside the box body 1.

[0042] It should be noted that since sand accumulation is likely to occur at the first to sixth corners and the middle part inside the box body 1, multiple nozzles 15 are respectively arranged facing the above-mentioned positions, which can effectively strengthen the sand-water flow at various positions inside the box body 1, so that the sand and water are fully stirred, effectively avoiding the situation of sand accumulation.
[0043] Furthermore, in this embodiment, the side surface of the box body 1 is inclined with respect to the bottom surface of the box body 1, and an obtuse angle is formed between the side surface of the box body 1 and the bottom surface of the box body 1. The partition plate 16 is inclined with respect to the bottom surface of the box body 1, and an obtuse angle is formed between the partition plate 16 and the bottom surface of the box body 1.
[0044] It should be noted that the design of the side surface of the box body 1 being inclined with respect to the bottom surface of the box body 1 and the partition plate 16 being inclined with respect to the bottom surface of the box body 1 can further avoid the situation of sand accumulation in the box body 1, and the above design, in cooperation with the nozzle 15, can accelerate the circulating flow of sand and water, further improving the uniformity of sand and water.
[0045] Furthermore, in this embodiment, the sandblasting assembly includes a sandblasting pump 4, a primary splitter 6, a secondary splitter 8, a second pipeline 7, and a third pipeline 9;

[0047] It should be noted that the sandblasting assembly in this embodiment is used to supply the sand and water in the box body 1 to other devices of the wet sandblasting equipment. Specifically, the sandblasting pump 4 extracts the sand and water in the box body 1 to the primary splitter 6. The sand and water after being split by the primary splitter 6 enter the secondary splitter 8 through the second pipeline 7, and the sand and water after being split by the secondary splitter 8 finally enter other devices through the third pipeline 9.
[0048] Specifically, in this embodiment, the primary splitter 6 is connected to three second pipelines 7, each second pipeline 7 is connected to a secondary splitter 8, and each secondary splitter 8 is connected to six third pipelines 9.
