Description

Technical Field

[0001] The utility model relates to the technical field of building material production machinery, in particular to a sand blasting machine with a dustproof structure. Background Art

[0002] Sand blasting machine is also called sand making machine. In the foundry machinery industry, sand blasting machine is a commonly used sand processing equipment. Specifically, there are hammer sand blasting machine, impact sand blasting machine, VSI sand making machine, PL sand making machine, impact sand making machine, high-efficiency compound fine crusher and other high-efficiency sand making products, which are widely used in the fine crushing of various minerals such as granite, basalt, limestone, river pebbles, cement clinker, quartz stone, iron ore, bauxite, etc.

[0003] During the use of the existing sand blasting machine, since the feed frame of the sand blasting machine is always in an open state, some dust will be added into the interior of the sand blasting machine through the feed port. When the sand blasting machine is used, the material will be mixed with the dust and crushed simultaneously, resulting in unqualified mixed dust and low dust prevention effect. At the same time, after the sand blasting is completed, the staff is required to manually hold a cleaning brush to brush and clean, which not only has low cleaning efficiency but also increases the work intensity of the staff.

[0004] In the patent document with publication number CN216731339U, a sand blasting machine with a dust removal structure is disclosed, which is provided with a rotating plate, a pulley, a ash baffle plate and a first spring. This arrangement cooperates with the rotational connection between the rotating plate and the pulley, the rotational connection between the ash baffle plate and the feed frame, and the rotational connection between the first spring and the rotating plate. When the sand blasting machine is not in use, the rotating plate and the ash baffle plate are closed in the opening position of the feed frame. Before use, the ash baffle plate and the rotating plate are cleaned, the material is added to the feed frame, the first spring is pushed to stretch, the feed port is opened, and the material is added to the inside of the sand blasting machine body, which effectively prevents dust from entering and improves the dust prevention effect.

[0040] Working principle:

[0041] Firstly, the dust raised by the feed inlet is sucked into the dust collecting box 406 by the dust collecting motor 403 through 401 through the feed inlet dust suction mechanism. The dust collecting box 406 can be pulled out by the pull ring 407 for regular cleaning. Secondly, the baffle 409 is used to prevent the dust raised by the material entering the sand blasting machine housing 2, so that the material cannot be discharged after entering. The dust entering is well controlled, and the material is prevented from splashing during processing, thereby increasing safety.

[0042] Furthermore, the water in the water tank 6 is pumped out through the water pump 602 and ejected from the nozzle 605. The ejected small water column can absorb the dust raised by the discharge port, and the dust can fall with the water droplets, effectively reducing the dust at the discharge port.

[0043] Furthermore, the output materials can be collected through the set collection box 9, and by pulling the handle 904, the inclined plate 903 can be driven to disperse the materials accumulated in one place, which is beneficial to the space utilization of the collection box 9.
