[0041] Transmission component 9 is a synchronous belt mechanism.

[0042] In this embodiment, the hydraulic cylinder 2 drives the sand grinding basket assembly 6 to move up and down, thereby performing grinding and dispersion operations. The motor 4 drives the connecting assembly 5 through the transmission assembly 9, which in turn drives the sand grinding basket assembly 6. The connecting assembly 5 enables quick assembly and disassembly of the sand grinding basket assembly 6, facilitating its replacement and making operation simple and convenient. The clamping assembly 7 can fix the bucket containing the steel structure fireproof coating, while ensuring that the sand grinding basket assembly 6 is located in the center of the bucket, improving grinding and dispersion efficiency.

[0043] Example 2

[0044] like Figures 3-6 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes:

[0045] The connecting component 5 includes a mounting plate 51, which is fixed to the bottom wall of the transmission beam 3. Connecting rods 52 are symmetrically fixed to the outer edge of the bottom wall of the mounting plate 51, and a transmission shaft 53 is rotatably mounted in the center of the mounting plate 51 through a bearing.

[0046] The top end of the drive shaft 53 is connected to the power output end of the motor 4 through the transmission assembly 9. The bottom end of the drive shaft 53 is fixed with a connector 54, and a threaded sleeve 55 is slidably installed on the bottom side wall of the drive shaft 53.

[0047] A limit block 56 is fixed at the bottom of the connecting rod 52, and a threaded sleeve 57 is screwed to the bottom of the connecting rod 52.

[0048] The connector 54 includes a rectangular block 541, which is fixed to the bottom of the drive shaft 53. The bottom of the rectangular block 541 has symmetrical movable grooves 542. Slide plates 543 are slidably installed in each movable groove 542. A spring 544 is fixed between the side wall of the slide plate 543 and the inner wall of the movable groove 542. A top ball 545 is fixed on the other side of the slide plate 543. The top ball 545 slides through the side wall of the rectangular block 541.

[0049] The sanding basket assembly 6 includes a basket body 61, with symmetrical arc-shaped limiting grooves 62 on the top wall of the basket body 61 that cooperate with the limiting block 56, and a drive shaft 63 rotatably mounted in the center of the basket body 61.

[0050] The top wall of the drive shaft 63 is provided with a rectangular connecting hole 64 that mates with the connector 54. The drive shaft 63 is fixed with a suction pump wheel 65 and a stirring rod 66 on the shaft inside the basket 61. The bottom end of the drive shaft 63 is fixed with a dispersing disc 68.

[0051] The suction pump wheel 65 is located at the top of the inner cavity of the sand grinding basket assembly 6;

[0052] A separator 67 is fixed to the bottom wall of the basket 61, and a drive shaft 63 passes through the center of the separator 67 via a bearing.

[0053] The inner wall of the rectangular connecting hole 64 is provided with a ball groove that mates with the ball 545, and the top end of the drive shaft 63 is provided with a thread that mates with the threaded sleeve 55.

[0054] The side wall of the basket 61 has a water outlet that communicates with the arc-shaped limiting groove 62.

[0055] In this embodiment, the connecting component 5 enables quick assembly and disassembly of the sanding basket assembly 6, facilitating its replacement and providing a simple and convenient operation. When installing the sanding basket assembly 6 onto the connecting component 5, first align the limiting block 56 with the wide end of the arc-shaped limiting groove 62, and simultaneously insert the connector 54 into the rectangular connecting hole 64. Rotate the basket body 61 to move the limiting block 56 into the arc-shaped limiting groove 62 until it reaches the innermost side. At this point, rotate the threaded sleeve 57 to ensure it fits tightly against the top of the basket body 61, thus connecting the connecting component 5 to the sanding basket assembly 6. Simultaneously, rotate the threaded sleeve 55 to screw it onto the top of the drive shaft 63, ensuring a stable connection between the drive shaft 53 and the drive shaft 63. The connector 54 provides initial positioning for the sanding basket assembly 6 during installation. The top ball 545 engages with the top ball groove, facilitating the suspension of the sanding basket assembly 6 at the bottom of the drive shaft 53 for easy installation.

[0056] The top wall of the base 1 has a mounting groove 8, and the clamping component 7 is installed in the mounting groove 8.

[0058] The clamping end of the clamping block 71 has a triangular groove, and a rubber pad is fixed to the clamping end of the clamping block 71.

[0059] In this embodiment, the clamping component 7 can clamp the material bucket directly below the sand grinding basket component 6, thereby improving the grinding and dispersion efficiency of the sand grinding basket component 6. When the clamping component 7 is working, the material bucket containing the steel structure fireproof coating is first placed in the mounting groove 8, and the knob 75 is rotated. The knob 75 drives the bidirectional screw 74 to rotate. During the rotation of the bidirectional screw 74, the slider 72 drives the two clamping blocks 71 to move closer to each other, thereby clamping and fixing the material bucket. The rubber pad can prevent the material bucket from being damaged during the clamping process.

[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
