The vibrating screen includes a vibrating screen body, a programmable logic controller (PLC), a power conversion module, a lifting mechanism, a fixed plate, and a fixed seat. The lifting mechanism also has a discharging mechanism and a blocking mechanism. The lower end of the lifting mechanism is mounted on the rear end of the fixed plate, and the upper end is hingedly mounted to the rear lower end of the vibrating screen body. The lower end of the fixed seat is mounted on the front end of the fixed plate, and the upper end is hingedly mounted to the front lower end of the vibrating screen body. A discharging port is provided at the lower front side of the vibrating screen body, and the discharging mechanism is mounted therein. The blocking mechanism includes an electric linear slide, an air compressor, and a rotating nozzle device. The electric linear slide is mounted on the lower part of the vibrating screen body, and the exhaust pipe of the air compressor is connected to the intake pipe of the rotating nozzle device via a hose. The PLC and power conversion module are mounted in a control box and electrically connected. The present invention can discharge large-particle material forward. High-flow compressed air is ejected upward from a rotating nozzle to flush the material remaining in the sieve hole, effectively clearing the material remaining in the sieve hole.

[0004] This patent and the prior art have the following technical problems in actual use:

[0005] 1. In the process of screening the ore, the existing vibrating screen is too wet, so the wet ore is easy to stick together and cannot be screened, so it needs to be improved.

[0006] 2. At the same time, the existing vibrating screen is often easily blocked by the mineral material during the screening process of the mineral material, thereby reducing the screening effect of the vibrating screen on the mineral material, so it needs to be improved. Summary of the Invention

[0007] The purpose of the present invention is to solve the above problems and provide a compressed air ore washing vibrating screen.

[0008] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0009] The top of the movable block is fixed with a toothed plate, and the top of the movable block is fixed with a toothed plate.

[0010] Furthermore, side blocks are fixedly installed at both ends of the empty box, the other end of the side block is fixedly connected to a support frame, the upper end of the support frame is fixedly connected to a rigid spring, the other end of the rigid spring is fixedly connected to a connecting frame, and the connecting frame is fixedly connected to the vibration box by screws.

[0011] Furthermore, a first disc is sleeved inside the closing block, a side surface of one end of the first disc is fixedly connected to the transmission wheel, one end of the first disc is hinged to a hinge block, the other end of the hinge block is hinged to a second disc, a fixed block is fixedly installed on the bottom of the empty box, a driving motor is fixedly installed between the fixed blocks, both ends of the driving motor are transmission-connected with a rotating rod, the other end of the rotating rod passes through the fixed block and is fixedly connected to the second disc, and the outer diameter of the second disc is larger than that of the first disc.

[0012] Furthermore, a second bifurcated pipe is fixedly connected to the interior of the lower end of the vibration box, and the other end of the second bifurcated pipe is connected to an external dust removal device.

[0013] Furthermore, a second connecting pipe is fixedly sleeved inside the upper end of the empty box, and one end of the second connecting pipe is located in the middle of the empty box.

[0014] Furthermore, the other end of the second connecting pipe is fixedly connected to a compressed gas tank, which is fixed to the lower end of the support frame. The other end of the compressed gas tank is fixedly connected to a gas pipe, which is connected to external gas transmission equipment.

[0015] Furthermore, blocking blocks are fixed at equal intervals on the top of the screen, and the blocking blocks are tilted at an angle opposite to the screen.

[0016] Furthermore, there are multiple blocking blocks, and the multiple blocking blocks are staggered with each other.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, when the vibrating vibration box drives the movable block to reciprocate and compress the air inside the empty box through the connecting block, the vibration box will drive the friction block to rub the copper cylinder to heat the compressed air inside the empty box, so that the compressed air inside the empty box is discharged into the closed block through the first bifurcation pipe and the first connecting pipe, and then the closed block discharges the compressed air into the rotating pipe and discharges it through the air jet hole, so that the compressed air ejected from the air jet hole cleans the clogged screen mineral material, and the heated compressed air dries the moist mineral material above and below the screen, thereby achieving the purpose of drying the mineral material and clearing the screen blockage.

[0019] 2. The present invention starts the driving motor, so that the fixed block drives the second disc to rotate, and then the second disc drives the first disc to rotate synchronously through the hinge block, so that the first disc drives all the rotating tubes to rotate through the transmission wheel and the transmission belt. At this time, since the outer diameter of the second disc is larger than that of the first disc, the second disc drives the vibration box to vibrate as a whole through the hinge block and the first disc, thereby achieving the purpose of rotating the rotating tube and vibrating the vibration box.

[0020] 3. The compressed air tank of the present invention introduces compressed air into the interior of the empty box through the second connecting pipe, so that the compressed air inside the empty box is heated by the friction of the copper cylinder, and at the same time, the reciprocatingly vibrating movable block compresses the compressed air inside the empty box and discharges it to the first bifurcation pipe, and then the first bifurcation pipe discharges the compressed air into the interior of the closed block through the first connecting pipe, so that the closed block introduces the compressed air into the interior of the rotating tube and discharges the compressed air through the air jet hole. By continuously introducing compressed air into the interior of the rotating tube, the screened mineral material will not enter the rotating tube through the air jet hole and cause blockage, thereby ensuring that the rotating tube can be used continuously.

DETAILED DESCRIPTION

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Example 1, as Figures 1-6 As shown, a compressed air mineral washing vibrating screen comprises a vibrating box 1, an inclined screen 2 is fixed inside the vibrating box 1, a feed port 3 is provided at the upper end of the vibrating box 1, a discharge port 4 is provided at the lower end of the vibrating box 1, a rotating tube 13 located at the bottom of the screen 2 is equidistantly sleeved inside the vibrating box 1, a closing block 12 is fixed on both sides of the vibrating box 1, an air jet hole 14 is opened inside the rotating tube 13, one end of the rotating tube 13 is fixedly connected to a transmission wheel 15 located inside the closing block 12, and the outer surface of the transmission wheel 15 is connected to the transmission There is a transmission belt 16, and the interior of one end of the closing block 12 is fixedly connected to the first connecting pipe 11, the other end of the first connecting pipe 11 is sleeved with the first bifurcated pipe 10, and the other end of the first bifurcated pipe 10 is fixedly connected to the empty box 6, the interior of the empty box 6 is fixedly sleeved with a copper cylinder 8, the interior of the copper cylinder 8 is frictionally sleeved with a friction block 9, the upper end of the friction block 9 is fixed to the vibration box 1, the interior of the empty box 6 is sleeved with a movable block 7, the top of the movable block 7 is fixed with a connecting block 5, the upper end of the connecting block 5 passes through the empty box 6 and is fixedly connected to the vibration box 1.

[0030] When the vibration box 1 vibrates, the vibration box 1 drives the friction block 9 to rub up and down along the inner wall of the copper cylinder 8. Due to the high-speed friction of the friction block 9 on the copper cylinder 8, the temperature of the copper cylinder 8 gradually increases, so that the copper cylinder 8 heats the air inside the empty box 6. At the same time, the vibrating vibration box 1 drives the movable block 7 to move back and forth along the inner wall of the empty box 6 through the connecting block 5. At this time, since the first bifurcated pipe 10 is connected to the empty box 6, the movable block 7 moves back and forth to compress the heated air inside the empty box 6 and discharge it to the first bifurcated pipe 10, and then the first bifurcated pipe 10 discharges the heated compressed air into the closed block 1 through the first connecting pipe 11 2. At this time, since the closing block 12 is connected to the multiple rotating tubes 13, the closing block 12 discharges the compressed air into the rotating tubes 13, and then the compressed air is discharged through the air jet holes 14. At this time, if the operator pours the wet ore through the feed port 3 onto the screen 2 for vibration screening, the heated compressed air ejected from the air jet holes 14 will dry the wet ore above and below the screen 2, making it easier for the dried ore to be vibrated and screened by the screen 2 and dried, so that the ore after screening can be discharged through the screen 2 to the inside of the lower end of the vibration box 1, thereby achieving the purpose of drying the wet ore by compressed air for screening;

[0031] When the transmission wheel 15 drives the air injection hole 14 on the rotating tube 13 toward the hole of the screen 2 through the transmission belt 16, and then when the vibrating vibration box 1 drives the movable block 7 to reciprocate and compress the air inside the empty box 6 through the connecting block 5, the compressed air inside the empty box 6 is discharged into the closing block 12 through the first bifurcated pipe 10 and the first connecting pipe 11, so that the closing block 12 discharges the compressed air into the rotating tube 13 and discharges it through the air injection hole 14, and then the compressed air ejected from the air injection hole 14 cleans the clogged screen 2 mineral material, thereby reducing the clogging of the screen 2 when vibrating and screening the mineral material, and thus achieving the purpose of cleaning the clogged screen 2 by compressed air.

[0032] Example 2, as Figure 1-Figure 2 As shown, side blocks 26 are fixedly installed at both ends of the empty box 6, the other end of the side block 26 is fixedly connected to the support frame 23, the upper end of the support frame 23 is fixedly connected to the rigid spring 24, the other end of the rigid spring 24 is fixedly connected to the connecting frame 25, and the connecting frame 25 is fixedly connected to the vibration box 1 by screws.

[0033] Through the design of the support frame 23 and the side block 26, the support frame 23 fixes the empty box 6 through the side block 26. Through the design of the rigid spring 24 and the connecting frame 25, the support frame 23 is movably connected to the vibration box 1 through the rigid spring 24 and the connecting frame 25. When the vibration box 1 is vibrating as a whole, the empty box 6 will be fixed by the support frame 23 and the side block 26 and cannot move.

[0034] Example 3, as Figure 2-Figure 6 As shown, the interior of the closing block 12 is sleeved with a first disc 17, the side surface of one end of the first disc 17 is fixedly connected to the transmission wheel 15, one end of the first disc 17 is hinged with a hinge block 18, and the other end of the hinge block 18 is hinged with a second disc 19. A fixed block 20 is fixedly installed at the bottom of the empty box 6, and a drive motor 21 is fixedly installed between the fixed blocks 20. The two ends of the drive motor 21 are transmission-connected with a rotating rod 22, and the other end of the rotating rod 22 passes through the fixed block 20 and is fixedly connected to the second disc 19. The second disc 19 has a larger outer diameter than the first disc 17.

[0035] By starting the drive motor 21, the fixed block 20 drives the second disc 19 to rotate, and then the second disc 19 drives the first disc 17 to rotate synchronously through the hinge block 18, so that the first disc 17 drives the transmission belt 16 to rotate through one of the transmission wheels 15, and then the transmission belt 16 drives all the rotating tubes 13 to rotate through multiple transmission wheels 15. At the same time, since the second disc 19 has a larger outer diameter than the first disc 17, the second disc 19 drives the vibration box 1 to vibrate as a whole through the hinge block 18 and the first disc 17, so that the vibrating vibration box 1 reciprocates and compresses the rigid spring 24, thereby achieving the purpose of rotating the rotating tube 13 and vibrating the vibration box 1.

[0036] Example 4, as Figure 1-Figure 2 As shown, the interior of the lower end of the vibration box 1 is fixedly connected to a second bifurcated pipe 31, and the other end of the second bifurcated pipe 31 is connected to an external dust removal device.

[0037] Through the design of the second bifurcated pipe 31, the external dust removal equipment can absorb and filter the compressed air inside the discharge port 4 through the second bifurcated pipe 31, reducing the situation where the compressed air inside the discharge port 4 blows the mineral dust to the outside world to pollute the environment, thereby protecting the working environment.

[0038] Example 5, as Figure 1-Figure 5 As shown, a second connecting pipe 30 is fixedly sleeved inside the upper end of the empty box 6, one end of the second connecting pipe 30 is located in the middle of the empty box 6, and the other end of the second connecting pipe 30 is fixedly connected to a compressed gas tank 28, which is fixed to the lower end of the support frame 23, and the other end of the compressed gas tank 28 is fixedly connected to a gas pipe 29, and the other end of the gas pipe 29 is connected to an external gas transmission equipment.

[0039] The external gas transmission equipment introduces the compressed air into the compressed gas tank 28 through the gas transmission pipe 29, and then the compressed air inside the compressed gas tank 28 is introduced into the empty box 6 through the second connecting pipe 30, so that the compressed air inside the empty box 6 is heated by the friction copper cylinder 8, and at the same time, the reciprocating movable block 7 will compress the compressed air inside the empty box 6 and discharge it to the first bifurcation pipe 10, and then the first bifurcation pipe 10 will discharge the compressed air into the closed block 12 through the first connecting pipe 11, so that the closed block 12 will introduce the compressed air into the rotating rotary tube 13, and then the compressed air will be discharged through the jet hole 14. In this way, the compressed air is continuously introduced into the rotary tube 13, so that the mineral material of the scoring screen will not enter the rotary tube 13 through the jet hole 14 and cause blockage.

[0040] Example 5, as Figure 1 As shown, blocking blocks 27 are fixed at equal intervals on the top of the screen 2. The blocking blocks 27 are tilted at an angle opposite to the screen 2. There are multiple blocking blocks 27, and the multiple blocking blocks 27 are staggered with each other.

[0041] Through the design of the blocking block 27, the blocking block 27 can block the falling speed of the mineral material on the screen 2, so that the mineral material can be better screened by the vibrating screen 2, thereby improving the mineral material screening effect of the equipment.

[0042] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
