[0002] Manufactured sand refers to sand processed by sand making machines and other auxiliary equipment. The finished product is more regular and can be processed into sand of different shapes and sizes according to different process requirements, which can better meet daily needs. However, the existing dust suppression equipment for manufactured sand processing is very inconvenient to handle and cannot recycle the dust generated by water spraying.

[0003] A prior art patent application with publication number CN221831891U discloses a dust suppression device for manufactured sand processing, including a processing device with a feed inlet fixedly connected to the top and a base fixedly connected to the bottom. A dust suppression mechanism is installed on the top of the base. The dust suppression mechanism includes a dust collection box with a storage box inside. This invention, by incorporating the dust suppression mechanism, allows the dust to enter the dust collection box through a fixed pipe during processing. A dust filter blocks the dust, which then passes through an outlet into a connecting pipe and into the storage box inside the dust collection box. Since the storage box is fixedly connected to a fixed plate via a slider, it can be removed using a handle for dust removal, thus improving dust suppression efficiency and enhancing environmental protection.

The processing equipment body 101 has a sliding hole 125, which is slidably engaged with the U-shaped frame 104. The cylinder 108 is fixedly connected to the processing equipment body 101 and located on one side of the processing equipment body 101. The output end of the cylinder 108 is fixedly connected to the U-shaped frame 104 and located on one side of the U-shaped frame 104. The side plate 103 is fixedly connected to the U-shaped frame 104 and located on the side of the U-shaped frame 104. On one side of 104, the limiting ring 105 is fixedly connected to the side plate 103 and the U-shaped frame 104 respectively, and the limiting ring 105 is in contact with the dustproof net 102. The locking bolt 106 is threadedly connected to the dustproof net 102 and the limiting ring 105 in sequence. The receiving bin 109 is connected to the processing equipment body 101 and is located below the processing equipment body 101.
