[0035] As Figs. 1-2 As shown, in the preferred scheme, vehicle basic frame 2 includes: bottom frame 6 and vertical rod 5, and a plurality of pairs of symmetrical vertical rods 5 are vertically arranged on bottom frame 6, wherein bottom frame 6 is rectangular, and sand collecting tray 3 is placed on the upper end surface of bottom frame 6 to collect sand material, and correspondingly, two pairs of vertical rods 5 are symmetrically arranged near the four corners of bottom frame 6, and first mounting groove and second mounting groove are sequentially formed on vertical rod 5 from high to low along the height, so as to realize the installation of sand storage tray 13, slide plate 12 and sand net 8.It is conceivable that the number of vertical rods 5 can be adaptively adjusted as needed, which is not limited here.

[0039] In the further scheme, the bearing 9 is sleeved on one end of the bearing shaft 10 protruding out of the first installation groove, and the other end of the bearing shaft 10 protruding out of the first installation groove is provided with a tightening nut. In this embodiment, the bearings 9 on the pair of vertical rods 5 arranged symmetrically are arranged oppositely, so that the sliding plate 12 can be directly placed on the bearing 9. After the sliding plate 12 is placed on the bearing 9, the sliding plate 12 needs to be ensured to be horizontally arranged, which can be tested by a level to adjust the height of the group of bearing 9, bearing shaft 10 and bearing retainer 11 in time, and be completely fastened by the tightening nut.
[0040] By sleeving the bearing 9 on the bearing shaft 10 and fixing it by using the tightening nut, the stable installation of the bearing 9 can be ensured; by directly placing the sliding plate 12 on the bearing 9, the horizontal arrangement of the sliding plate 12 can be conveniently ensured by adjusting the height of the bearing 9, bearing shaft 10 and bearing retainer 11; at the same time, the arrangement of the bearing 9 can significantly reduce the resistance of the sliding plate 12 during sliding, so that the movement is more smooth. The cooperation relationship between the components is simple, and the installation and disassembly are easy.

[0046] In the embodiment, two layers of sand screen 8 are provided to meet the filtering requirements of sand spraying. It is conceivable that the number of sand screens 8 can be increased or decreased as needed, and no further limitation is made here.
[0047] In order to realize the placement of the module, a cross beam is arranged between the pair of opposite vertical rods 5, and a clamping groove is arranged on the cross beam. The cross beam is located below the sand screen 8. When the sand spraying operation is performed, one end of the shaft of the module is placed on the clamping groove, and the other end is manually held and manually driven to rotate the shaft to drive the module to rotate and complete the sand spraying operation. By arranging the clamping groove on the cross beam, the module can be conveniently placed on the clamping groove without the need for additional fixing devices or tools, simplifying the installation and disassembly process of the module and making the sand spraying operation more efficient. The arrangement of the clamping groove also ensures the stability of the module shaft during rotation. One end of the module is placed on the clamping groove, and the other end is manually held. This structure makes the module not easy to shake or tilt during rotation, thereby ensuring the uniformity and consistency of the sand spraying operation.
[0048] It is conceivable that as an alternative embodiment, a cross beam can also be arranged on the other pair of vertical rods 5, and a clamping groove can be arranged on the cross beam, so that both ends of the shaft of the module can be placed on the clamping groove, and a hand wheel can be arranged on the end of the shaft extending out of the clamping groove to drive the module to rotate or be driven by electricity. No further limitation is made here.
