Description

Technical Field

[0001] The present application relates to the technical field of grain processing equipment, and more specifically, to a suction-type specific gravity stone remover. Background Art

[0002] When the gravity stoner is working, the material continuously enters the middle of the stone removal screen surface from the feed hopper. Due to the vibration of the screen surface and the action of the airflow passing through the material layer, the porosity between the particles increases, the material is in a fluidized state, and automatic classification is promoted. The stones with higher specific gravity sink to the bottom layer and contact the screen surface, while the grains with lower specific gravity float to the upper layer and slide down to the clean grain outlet under the push of gravity, inertia and continuous feeding. The stones with higher specific gravity slide relative to the stone removal screen surface under the action of the inertia force of the screen surface vibration system and the airflow, and move to the selection area through the stone gathering area.

[0003] According to the search, the Chinese patent with announcement number CN215656442U discloses a suction-type specific gravity stone removing machine, which includes a screen body, the upper surface of the screen body is provided with a suction device, the lower side of the screen body is provided with a bottom plate, the upper surface of the bottom plate is fixedly connected to two first support legs, the upper surface of the bottom plate is provided with a second support leg, the adjustment mechanism includes a control shell, the control shell is fixedly connected to the upper surface of the bottom plate, and a movable shaft is rotatably connected between the front and rear inner walls of the control shell, and two threaded blocks are movably sleeved on the movable shaft. The suction-type specific gravity stone removing machine is provided with an adjustment mechanism, so that the shaking mechanism can move up and down in the vertical direction and be positioned at any position, thereby achieving the effect of stepless adjustment, reducing the operating difficulty of the staff during adjustment, further ensuring the efficiency of adjusting the angle of the shaking mechanism, and also ensuring the work efficiency of destoning millet.

[0004] Regarding the above-mentioned related technologies, the applicant believes that the shaking mechanism thereof is not provided with a corresponding auxiliary reset mechanism, resulting in the weight of the entire screen body being borne by the shaking mechanism, which causes the shaking mechanism to be under a lot of pressure and easily damaged. For this reason, we propose a suction-type specific gravity stone remover. Utility Model Content

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] See also Figure 1-4 A suction-type specific gravity stone removing machine includes a main module 100 and a working module 200. The main module 100 includes a mounting frame assembly 110. A screen assembly 120 is provided on the top of the mounting frame assembly 110. A suction device 130 is provided on the screen assembly 120. The working module 200 is arranged between the mounting frame assembly 110 and the screen assembly 120. The working module 200 includes four auxiliary reset assemblies 210, each of which is arranged between the mounting frame assembly 110 and the screen assembly 120. Two drive assemblies 220 are provided on the mounting frame assembly 110, and the two drive assemblies 220 are both connected to the screen assembly 120.

[0038] By setting the mounting frame assembly 110, the auxiliary reset assembly 210 can be easily installed. By setting the screen assembly 120, grains can be screened and de-stoned. By setting the suction device 130, the screen assembly 120 can be assisted in screening and de-stoneing grains. By setting the auxiliary reset assembly 210, the screen assembly 120 can be assisted in lifting and resetting, thereby reducing the working pressure of the drive assembly 220. By setting the drive assembly 220, the screen assembly 120 can be driven to lift and lower to facilitate screening and de-stoneing of grains.

[0039] The mounting frame assembly 110 includes a mounting frame base 111, and the top of the mounting frame base 111 is fixedly connected to two first bases 112 and two second bases 113. The screen body assembly 120 includes a screen body main body 121 arranged above the mounting frame base 111, the air suction device 130 is arranged on the top of the screen body main body 121, and a screen body 122 is arranged inside the screen body main body 121. The auxiliary reset assembly 210 includes four spring members 211 respectively fixedly connected to the tops of the two first bases 112 and the two second bases 113, and the tops of the four spring members 211 are fixedly connected to special-shaped connecting blocks 212. The auxiliary reset assembly 210 also includes four connecting columns 213 respectively fixedly connected to both sides of the screen body 121, and the four connecting columns 213 are respectively movably connected to the inside of the four special-shaped connecting blocks 212. A threaded member 214 is provided between each connecting column 213 and each special-shaped connecting block 212.

[0040] When the sieve body 121 needs to be disassembled, the threaded member 214 is first disassembled to release the fixation of the connecting column 213. At this time, the sieve body 121 is lifted upward to drive the connecting column 213 to withdraw from the special-shaped connecting block 212, so that the sieve body 121 can be disassembled.

[0041] The drive assembly 220 includes a mounting base 221 fixedly connected to the mounting frame base 111, a drive motor 222 fixedly connected to the top of the mounting base 221, a disc 223 fixedly connected to the output end of the drive motor 222, a first limiting column 224 fixedly connected to one side of the disc 223, the drive assembly 220 also includes a fixed column 225 fixedly connected to one side of the screen body 121, one end of the fixed column 225 fixedly connected to the second limiting column 226, the drive assembly 220 also includes a connecting rod 227 movably sleeved between the first limiting column 224 and the second limiting column 226.

[0042] By starting the drive motor 222, the drive motor 222 will drive the first limiting column 224 to rotate through the disc 223, and the first limiting column 224 will pull the screen body 121 back and forth through the connecting rod 227, the second limiting column 226 and the fixed column 225 to facilitate the screening of grain and removal of stones.

[0043] The implementation principle of the embodiment of the present application is as follows: when work is required, the suction device 130 can be started first to suck air, and then the grain that needs to be de-stoned is added to the inside of the screen body 121 and located on the screen body 122, and then the drive motor 222 is started. The drive motor 222 will drive the disc 223 to rotate, and the disc 223 will drive the connecting rod 227 to rotate and achieve reciprocating lifting through the first limiting column 224, so that the connecting rod 227 can drive the fixed column 225 to reciprocate and lift through the second limiting column 226, and then can pull the screen body 121 up and down back and forth, so as to facilitate the screening and de-stoneing of the grain. During the lifting and lowering process of the screen body 121, the screen body 121 will drive the spring part 211 to expand and contract through the connecting column 213 and the special-shaped connecting block 212, so that the spring part 211 can assist the screen body 121 to reset, thereby reducing the pressure of the drive component 220 and improving the practicality of the machine.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
