Technical Field
[0001] This utility model relates to the field of manufactured sand technology, specifically a crushing device for manufactured sand. Background Technology
[0002] Manufactured sand refers to sand produced through sand making machines and other auxiliary equipment. The finished product is more regular in shape and can be processed into sand of different shapes and sizes according to different process requirements, better meeting daily needs. Specialized equipment is required to produce qualified and suitable sand and gravel.
[0003] In current manufactured sand production, the stone is first coarsely processed before being conveyed by a conveyor belt into the fine processing structure. This makes the operation inconvenient, and the open structure causes dust to fly everywhere, affecting the surrounding environment. In addition, some already crushed stone is re-entered into the fine processing equipment, resulting in waste. Utility Model Content

An auxiliary side box is horizontally fixedly installed on one side of the main support box. A support connecting box is fixedly installed on the side of the auxiliary side box away from the main support box. A power unit is fixedly installed on the inner side of the side fixing box. A top passage is horizontally opened on the top surface of the main support box. The main support box has a fixed inner block horizontally welded to its inner side. A movable toothed body is engaged with the inner side of the channel of the fixed inner block. A support frame is obliquely fixed to the inner side of the main support box. A screening screen is fixedly engaged with the inner side of the support frame. A fine treatment box is horizontally fixed to the inner side of the main support box. A through slot is opened on the top surface of the fine treatment box. A crushing screw roller is horizontally and symmetrically engaged with the inner side of the through slot. An extension shaft is symmetrically inserted at both ends of the crushing screw roller. A transmission gear is provided on the inner side of the auxiliary side box. A transmission motor is fixedly provided on the inner side of the support connecting box.
[0007] In a preferred embodiment of this utility model, the bottom surface of the main support box is open, and there are two mounting side strips. The two mounting side strips are fixedly and symmetrically arranged at the top two sides of the main support box, and the fixing through holes are arranged horizontally and equidistantly in a straight line at the center line of the top surface of the mounting side strips.
[0008] In a preferred embodiment of this utility model: the bottom opening end of the feeding hopper is fixedly connected to the top opening end of the top through groove to maintain communication, the side fixing box is fixedly installed on the side centerline of the main support box near the top, and the isolation rubber plate is snapped on the bottom edge of the main support box by the top surface clip.
[0009] In a preferred embodiment of the present invention: the output end of the power unit extends through the side wall of the main support box into the interior, and the extended end is connected and disposed on the side of the movable tooth body. The top through slot is horizontally opened at the end of the top surface of the main support box near the power unit.
[0010] In a preferred embodiment of this utility model: the fixed inner block is horizontally fixedly installed at one end of the inner top surface of the main support box, and the top surface of the fixed inner block is provided with a channel structure. The movable tooth is movably engaged in the slot hole inside the channel on the top surface of the fixed inner block. The support frame is inclinedly fixedly installed at the bottom surface near the fixed inner block, and the inclined downward end of the support frame is fixedly connected to the top edge of the fine treatment box. The fine treatment box is horizontally fixedly installed at one end of the bottom surface of the inner side of the main support box.
[0011] In a preferred embodiment of this utility model: the through slot is opened through the center of the top surface of the fine treatment box, the crushing screw rollers are symmetrically arranged on the inner side of the through slot near the bottom opening end, one end of the extension shaft extends horizontally and is inserted into the inner side of the auxiliary side box, and the extension end is correspondingly fixedly inserted into the center of the transmission gear, the transmission gears are toothed to each other, and the output end of the transmission motor extends and is fixedly connected to one end of an extension shaft.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention involves horizontally placing the main support box into a designated installation channel, securing the side strips by bolts passing through the fixing holes, and then feeding material into the top feeding hopper. Guided by the top through-slot at the bottom, the material falls downwards into the top channel of the fixed inner block. Controlled by the side power unit, the output end drives the movable teeth in a meshing motion within the fixed inner block. These teeth, in conjunction with the internal fixed tooth structure, crush the falling stones. The crushed material falls downwards onto the top surface of the screening screen below, where it is further crushed by the screening screen. The material undergoes initial screening, while coarser material rolls downwards into the through-channel. The side-mounted transmission motor rotates, causing the output end to drive the transmission gears, which in turn drive the crushing screw rollers to further crush the falling stones. Finally, all material is discharged through the bottom opening of the main support box. The bottom isolation plate effectively prevents stones from splashing and causing injury. The integrated sealed structure ensures safer and more reliable operation, while the dual crushing structure makes the crushing process more efficient and comprehensive. Attached Figure Description
