[0026] 3. Again, the output end of the third stepping motor of the present invention drives the third lead screw to rotate, making the L - shaped plate slide to the right along the guide rod, thereby driving the cover, the spiral motor and the spiral conveyor shaft to move to the right as a whole, realizing completely moving the spiral conveyor shaft to the outside of the feeding cylinder.

[0045] The moving mechanism 3 is installed on the front and rear sides of the screening box 104 and is used for moving the screening plate 105 to the outside or inside of the screening box 104.

[0046] The blockage clearing mechanism 4 is arranged at the position near the left side of the top of the chassis 1 and is used to prevent the screening plate 105 from being blocked.

[0047] The opening and closing mechanism 5 is installed on the top of the screening box 104 and is used to control the opening and closing of the open end of the screening box 104.

[0048] The feeding mechanism 6 is arranged inside the rotating member 107 and is used to add materials into the screening box 104 and conduct coarse screening on the materials.

[0049] Please refer to Figure 2 As shown, the vibrating mechanism 2 includes a fixed seat 201 and a mounting seat 205. There are two groups of fixed seats 201, and both are fixedly installed at the left top end of the chassis 1. There are four groups of mounting seats 205, and all are fixedly connected to the top end of the chassis 1. A rotating rod 202 is rotatably connected inside the two groups of fixed seats 201. Both ends of the rotating rod 202 are fixedly connected with a first connecting arm 203. The other end of the first connecting arm 203 is hinged to the second connecting arm 204. The other end of the second connecting arm 204 is hinged to the bottom end of the back of the triangular plate 206. One side of the top end of the triangular plate 206 is hinged to the outside of the mounting seat 205, and the other side of the top end of the triangular plate 206 is hinged to the connecting member 207. The top ends of the four groups of connecting members 207 are all fixedly connected to the bottom end of the movable plate 103. The bottom end of the front side of the left triangular plate 206 is rotatably connected with a third connecting arm 208. The other end of the third connecting arm 208 is rotatably connected to the bottom end of the front side of the right triangular plate 206.

[0050] Please refer to Figure 2 As shown, a driven gear 209 is fixedly connected to the middle of the outer surface of the rotating rod 202. A driving motor is fixedly installed at the bottom end of the chassis 1. The output end of the driving motor is fixedly connected with a driving gear 210. The driving gear 210 is in transmission connection with the driven gear 209 through a chain 211.

[0051] Those skilled in the art can understand that by driving the driving gear 210 to rotate through the output end of the driving motor, under the action of the chain 211, the driven gear 209 and the rotating rod 202 as a whole rotate synchronously. Then the two groups of first connecting arms 203 rotate, making the second connecting arm 204, the triangular plate 206 and the third connecting arm 208 all in a rotating state, and then achieving a vibrating state, thereby realizing the screening of the materials, and the screening effect is better.

[0052] Please refer to Figure 6 As shown, the moving mechanism 3 includes a fixed block 301, a lead screw 302, a guide rail 303 and a movable block 304. Two groups of fixed blocks 301 are fixedly installed on the front and rear sides of the screening box 104. The first lead screw 302 is rotatably connected between the two groups of fixed blocks 301. A movable block 304 is threadedly connected to the outer surface of the first lead screw 302. The outer sides of the movable blocks 304 on the front and rear sides are fixedly connected to a moving plate 306 through a connecting rod 305. The right side of the moving plate 306 is detachably connected to the screening plate 105. One end of the first lead screw 302 penetrates through the inner wall of the right fixed block 301 and is fixedly connected to a runner 307. The two runners 307 are driven by a belt 308. The middle part of the outer side of one of the runners 307 is fixedly connected to the output end of a first stepping motor 309, and the first stepping motor 309 is fixedly installed outside the screening box 104.

[0053] Please refer to Figure 6 As shown, the two ends of the guide rail 303 are respectively fixedly connected to the inner walls of the left and right fixed blocks 301. The movable block 304 is slidably connected to the outer surface of the guide rail 303. Slide plates 310 are fixedly installed on both sides of the screening plate 105. Sliding grooves adapted to the slide plates 310 are formed in the front and rear sides inside the screening box 104, and the slide plates 310 are slidably connected to the sliding grooves.

[0054] Those skilled in the art can understand that by driving one of the runners 307 to rotate through the output end of the stepping motor 309, the two first lead screws 302 rotate synchronously under the drive of the belt 308. Then, the two movable blocks 304 slide synchronously along the outer surface of the guide rail 303, driving the connecting rod 305, the moving plate 306 and the screening plate 105 to move as a whole, so that the screening plate 105 moves out of the inside of the screening box 104 and is located on the left side of the screening box 104. Similarly, when the output end of the stepping motor 309 rotates in the reverse direction, the screening plate 105 can be sent back into the inside of the screening box 104. Moreover, the moving plate 306 and the screening plate 105 are detachably connected, and the staff can replace the screening plates 105 of different specifications according to actual requirements.

[0055] Please refer to Figure 3 As shown, the blockage clearing mechanism 4 includes a second lead screw 401, a support rod 402, a second stepping motor 403, a lifting member 404 and a blockage clearing rod 405. The second lead screw 401 is rotatably connected to the top left side of the chassis 1. Two support rods 402 are provided and are located on both sides of the second lead screw 401, and the support rods 402 are fixedly installed on the top left side of the chassis 1.

[0056] Please refer to Figure 3As shown, the lifting member 404 is threadedly connected to the outer surface of the second lead screw 401. The lifting member 404 is slidably connected to the outer surface of the support rod 402. The second stepper motor 403 is fixedly installed on the top of the chassis 1. The top of the second lead screw 401 is fixedly connected to the output end of the second stepper motor 403. A plurality of groups of blockage clearing rods 405 are fixedly installed at the bottom of the lifting member 404.

[0057] Those skilled in the art can understand that by driving the second lead screw 401 to rotate reciprocally through the output end of the second stepper motor 403, the lifting member 404 slides up and down along the outer surface of the support rod 402, thereby driving a plurality of groups of blockage clearing rods 405 to move up and down reciprocally. And when the screening plate 105 is completely moved to the left side of the screening box 104, the positions of the plurality of groups of blockage clearing rods 405 correspond to the positions of the screening holes on the screening plate 105. Therefore, when the plurality of groups of blockage clearing rods 405 move downward synchronously, they can extend into the interior of the screening holes, flush out the materials blocked in the interior of the screening holes, and the flushed materials fall on the conveyor belt 102 below for conveying.

[0058] Please refer to Figure 4 and Figure 5 As shown, the opening and closing mechanism 5 includes a connecting block 501, a threaded rod 502, a fixed rod 503, a servo motor 504 and a cover plate 505. There are two groups of connecting blocks 501 and both are fixedly installed on the front side of the screening box 104. The two ends of the threaded rod 502 are respectively rotatably connected inside the two groups of connecting blocks 501. The thread directions of the threads opened at the two ends of the threaded rod 502 are opposite. There are two groups of cover plates 505 and they are respectively threadedly connected to the two ends of the outer surface of the threaded rod 502. The cover plates 505 are slidably connected to the outer surface of the fixed rod 503. The two ends of the fixed rod 503 are respectively fixedly connected to the inner walls of the two groups of connecting blocks 501. The servo motor 504 is fixedly installed on the outside of one of the connecting blocks 501, and one end of the threaded rod 502 is fixedly connected to the output end of the servo motor 504.

[0059] Those skilled in the art can understand that by driving the threaded rod 502 to rotate reciprocally through the output end of the servo motor 504, the two groups of cover plates 505 approach or move away from each other. When approaching, the top opening of the screening box 104 is covered, and when moving away, the top opening of the screening box 104 is exposed.

[0060] Please refer to Figure 7As shown in the figure, the feeding mechanism 6 includes a feeding cylinder body 601, which is fixedly installed inside the rotating part 107. At the bottom of one end of the feeding cylinder body 601 close to the screening box 104, a number of groups of filtering holes 602 are evenly opened. At one end of the feeding cylinder body 601 far from the screening box 104, there is a cover 603. The aperture of the filtering holes 602 is larger than that of the screening holes on the screening plate 105, and a spiral motor 604 is fixedly installed on the outer side of the cover 603. A spiral conveyor shaft is arranged inside the feeding cylinder body 601.

[0061] Please refer to Figure 7 As shown in the figure, a third lead screw 605 is rotatably connected to the outer side of the feeding cylinder body 601. A guide rod 606 is also fixedly installed on the outer side of the feeding cylinder body 601. An L-shaped plate 608 is slidably connected to the outer surface of the guide rod 606. The L-shaped plate 608 is threadedly connected to the outer surface of the third lead screw 605. The long plate of the L-shaped plate 608 is fixedly connected to the cover 603. A third stepping motor 607 is fixedly installed on the outer side of the feeding cylinder body 601. One end of the third lead screw 605 is fixedly connected to the output end of the third stepping motor 607.

[0062] Those skilled in the art can understand that the material is placed inside the feeding cylinder body 601, and the feeding cylinder body 601 is in a horizontal state. The spiral motor 604 drives the spiral conveyor shaft to rotate, so as to push the material from the right side to the left side inside the feeding cylinder body 601. The aperture of the filtering holes 602 is larger, realizing the first screening of the material, that is, rough screening. Also, the output end of the third stepping motor 607 drives the third lead screw 605 to rotate, so that the L-shaped plate 608 reciprocates left and right along the guide rod 606, thereby driving the cover 603, the spiral motor 604 and the spiral conveyor shaft to move left and right as a whole, realizing the complete movement of the spiral conveyor shaft inside or outside the feeding cylinder body 601.

[0063] The usage process of this device is as follows. First, the material is placed inside the feeding cylinder body 601, and the feeding cylinder body 601 is in a horizontal state. The spiral motor 604 drives the spiral conveyor shaft to rotate, so as to push the material from the right side to the left side inside the feeding cylinder body 601. The aperture of the filtering holes 602 is larger, realizing the first screening of the material, that is, rough screening.

[0064] The material falling from the filtering holes 602 enters the inside of the screening box 104. The output end of the servo motor 504 drives the threaded rod 502 to rotate, so that the two cover plates 505 approach each other and cover the top opening of the screening box 104.

[0065] Secondly, the output end of the drive motor drives the drive gear 210 to rotate. Under the action of the chain 211, the driven gear 209 and the rotating rod 202 are driven to rotate synchronously as a whole. Further, the two groups of first connecting arms 203 rotate, causing the second connecting arm 204, the triangular plate 206, and the third connecting arm 208 to be in a rotating state, thereby achieving a high-frequency vibration state, and thus realizing the second screening of the material. The aperture of the screening holes on the screening plate 105 is relatively small, which is a fine sieve here. The material passing through the screening holes meets the particle size requirements and falls on the conveyor belt 102, and is conveyed by the conveyor belt 102 to the external collection box;

[0066] If the screening holes on the screening plate 105 are blocked, the output end of the stepper motor 309 drives one of the rotating wheels 307 to rotate. Driven by the belt 308, the two first lead screws 302 on both sides rotate synchronously. Further, the two movable blocks 304 slide synchronously along the outer surface of the guide rail 303, driving the connecting rod 305, the moving plate 306, and the screening plate 105 to move as a whole, so that the screening plate 105 moves out of the screening box 104 and is located on the left side of the screening box 104. The positions of several groups of clogging clearing rods 405 correspond to the positions of the screening holes on the screening plate 105. Then, the output end of the second stepper motor 403 drives the second lead screw 401 to rotate, causing the lifting member 404 to slide downward along the outer surface of the support rod 402, thereby driving several groups of clogging clearing rods 405 to move downward, and then they can extend into the interior of the screening holes to flush out the material blocked in the screening holes, and the flushed material falls on the conveyor belt 102 below and is also conveyed to the external collection box;

[0067] When it is necessary to remove large-particle impurities inside the feeding cylinder 601, the output end of the third stepper motor 607 drives the third lead screw 605 to rotate, causing the L-shaped plate 608 to slide to the right along the guide rod 606, thereby driving the cover 603, the spiral motor 604, and the spiral conveyor shaft to move to the right as a whole, realizing the complete movement of the spiral conveyor shaft to the outside of the feeding cylinder 601. Secondly, the output end of the transmission motor 106 drives the rotating member 107 to rotate, causing the right end of the feeding cylinder 601 to tilt downward, then the large-particle impurities will slide out, which is convenient and fast.

[0068] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
