Description

Technical Field

[0001] The utility model mainly relates to the field of stone removal equipment, in particular to a specific gravity stone removal machine. Background Art

[0002] The specific gravity stone remover is a kind of impurity removal equipment that utilizes the difference in density and suspension speed between granular materials (paddy, brown rice, rice, wheat, etc.) and minerals (mainly siderophore, etc.), and uses mechanical wind power and a screen surface that reciprocates in a certain trajectory to separate minerals from granular materials. It is an essential key equipment in rice processing technology.

[0003] In the invention patent application with application number CN202320193457.3, application publication date 2023.09.26, and name "A specific gravity stone removing machine for preventing screen clogging", it includes a specific gravity stone removing machine body and an anti-blocking component, wherein a feed port is fixedly connected to the top of the specific gravity stone removing machine body, a screening net is movably connected to a surface of one side of the specific gravity stone removing machine body, and an anti-blocking component is fixedly connected to the outer surface of the screening net, and the anti-blocking component comprises a support frame, a drive motor, a transmission rod, a toggle plate, a connecting box, a spring, a bottom plate, a connecting plate, an electric lifting rod and a vibration plate, the support frame is fixedly connected to the outer surface of the screening net, and the device moves the bottom plate upward inside the connecting box while rotating the toggle plate. When the toggle plate is separated from the surface of the bottom plate, the bottom plate is quickly ejected downward by the extrusion of the spring, thereby driving the vibration plate to hit the surface of the screening net to dredge the screening net.

[0004] In actual use, the gravity stone remover can only clean and separate the heavier stones in the granular materials, but cannot clean the dust which is lighter than the granular materials. The separated materials need to be cleaned again. After working for a long time, even if the surface of the screening net is cleared many times, there are still dead corners that cannot be cleaned. Therefore, the screening net needs to be replaced, but the replacement of the existing screening net is cumbersome. Utility Model Content

The equipment absorbs dust in the material through the ash-absorbing roller 604 in the ash suction box 6, and the quick replacement of the embedded screen 707 is realized through the replacement groove arranged on the surface of one side of the rock box 3.

[0028] The dust suction box 6 includes an outer box body 601, a water storage tank 602 is arranged inside the outer box body 601, a wetting hole 603 is arranged below the water storage tank 602, a dust roller 604 is movably connected to the inner surface of the outer box body 601 below the wetting hole 603, a transmission belt 605 is arranged on one side of the dust roller 604, a socket 606 is arranged on the top surface of the outer box body 601 above the dust roller 604, a cleaning brush 607 is movably connected to the surface of the socket 606, a limiting spring piece 608 is arranged on the surface of the cleaning brush 607, the dust roller 604 forms a transmission structure with the screen mechanism 7 through the transmission belt 605, the cleaning brush 607 is fixed to the surface of the socket 606 by the limiting spring piece 608, and one end of the cleaning brush 607 is contacted with the dust roller 604 by pressing the cleaning brush 607, and a plurality of wetting holes 603 are arranged, and they are distributed in a straight line above the dust roller 604.

[0029] In this embodiment, when the granular material is de-stoned, the granular material is poured into the rock box 3 through the feed port 4, and the high-power fan 2 separates the granular material by the air flow inside the rock box 3. The heavier stone particles fall to the surface of the crushed stone chute 5 and slide out, while the granular material and dust enter the dust suction box 6 and first pass through the surface of the dust-sucking roller 604. The dust-sucking roller 604 is wetted by the water in the water storage tank 602 falling from the wetting dripping hole 603 to the surface of the dust-sucking roller 604, so that the dust-sucking roller 60 4 is used to adsorb the dust mixed in the granular material, and the remaining granular material is screened by the screen mechanism 7. When it is necessary to clean the surface of the dust-stained roller 604, the cleaning brush 607 is pressed down to make the cleaning brush 607 contact with the dust-stained roller 604. Under the action of the screen mechanism 7, the dust-stained roller 604 rotates and the surface of the dust-stained roller 604 is cleaned by the brush head end of the cleaning brush 607 and the water dripping from the wetting hole 603, thereby finally realizing the cleaning of the dust in the granular material and the self-cleaning of the surface of the dust-stained roller 604.

[0031] In this embodiment, after the dust is removed, the particulate material passes through the dust-collecting roller 604 and falls onto the surface of the interlocking screen 707 in the screen mechanism 7. By starting the transmission motor 702, on the one hand, the transmission belt 605 and the dust-collecting roller 604 are driven to rotate, and on the other hand, the eccentric turntable 704 is driven to rotate, thereby causing the swing arm 705 to drive the screen frame 706 to move left and right, so that the interlocking screen 707 on the surface of the screen frame 706 screens the material. When a large amount of debris is attached to the surface of the interlocking screen 707, the interlocking screen 707 is removed from the surface of the screen frame 706 through the replacement groove provided on the surface of one side of the rock drop box 3, and a new interlocking screen 707 is embedded in the screen frame 706, thereby achieving the purpose of convenient replacement.
