[0002] In coal mining and processing, the handling of coal gangue is a crucial step. Traditional methods often involve conveying followed by screening, or screening followed by secondary conveying. This separate process has several drawbacks. Firstly, it requires a large footprint, necessitating multiple conveying and screening systems, increasing construction costs and space requirements. Secondly, multiple transfers not only consume significant time and energy but also easily lead to coal gangue spillage and environmental pollution. Furthermore, existing screening equipment is insufficient in terms of screening precision and efficiency, failing to meet the demands of modern coal production for refined coal gangue processing. For example, some vibrating screens are prone to screen clogging during screening, affecting screening efficiency and production continuity. Therefore, developing a synchronous coal gangue conveyor that integrates screening and conveying functions while improving both screening precision and conveying efficiency is of significant practical importance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Example 1, by Figures 1-4The present invention includes a ground surface 1, which supports the entire device. A screening box 2, made of alloy material, is mounted on top of the ground surface 1. The screening box 2 is used for screening coal gangue. A funnel 205, also made of alloy material, is fixed to the bottom of the screening box 2. A secondary screening plate 601, made of alloy material, is slidably connected inside the screening box 2. A primary screening plate 6, also made of alloy material, is slidably connected to the top of the secondary screening plate 601. The primary screening plate 6, also made of alloy material, is slidably connected to the screening box 2. Both the primary and secondary screening plates 601 have several through holes, with the inner diameter of the through holes on the primary screening plate 6 being larger than that on the secondary screening plate. The inner diameter of the through hole on plate 601 allows the primary screening plate 6 and the secondary screening plate 601 to be replaced according to the required size of the coal gangue to be screened, thereby improving the applicability and convenience of the entire device. Each of the primary screening plate 6 and the secondary screening plate 601 has a replacement plate 4 at its front end. The replacement plate 4 is made of alloy material and is used to position the primary screening plate 6 and the secondary screening plate 601. A replacement head 401 is fixed to the lower end of each replacement plate 4. The replacement head 401 is made of alloy material and is rotatably connected to the screening box 2 via a rotating shaft. The replacement head 401 is used to position the replacement plate 4. Each replacement plate 4 has two spring plates 8 at its top, which are fixedly connected to the screening box 2. Next, the spring plate 8 is made of alloy material and is used to position the stabilizing rod 801. Each spring plate 8 has a stabilizing block 802 at its bottom, which is also made of alloy material. The stabilizing block 802 applies force to the screening plate positioning shaft 602, thereby ensuring the stability of the lifting and lowering of the primary screening plate 6 and the secondary screening plate 601, thus ensuring the vibrating effect and the stability of coal gangue screening. Each replacement plate 4 also has a vibrating screen auxiliary head 702 at its outer end. The vibrating screen auxiliary head 702 has a crescent structure and is made of alloy material, thus ensuring the stability of the screening plate positioning shaft 602. Each vibrating screen auxiliary head 702 has a vibrating screen main head 7 at its bottom. The main vibrating screen head 7 has a semi-circular bottom structure, with protrusions at both ends. Made of alloy material, the main vibrating screen head 7 rotates to allow the auxiliary vibrating screen head 702 to reciprocate up and down, thereby driving the primary screening plate 6 and the secondary screening plate 601 to reciprocate up and down, thus completing the vibrating screen and achieving the purpose of screening coal gangue. This ensures the accuracy and efficiency of screening, guaranteeing the screening effect. A primary channel 203, made of alloy material, is fixed to the left end of the screening box 2. This primary channel 203 is used to transport the coal gangue from the top of the primary screening plate 6.

A baffle 3, also made of alloy material, is slidably connected inside the primary channel 203 and the secondary channel 204. The baffle 3 can control the opening and closing of the primary channel 203 and the secondary channel 204 by moving, thereby preventing unscreened coal gangue from falling from the primary channel 203 and the secondary channel 204, further ensuring screening accuracy. Several positioning holes 403 are provided at the rear end of the screening box 2 and on the two replacement plates 4. These positioning holes 403 are used to position the screening plate positioning shaft 602 and provide a moving path for it. A screening plate positioning shaft 602, made of alloy material, is slidably connected inside each positioning hole 403 and is used to position the primary screening plate 601 and the secondary screening plate 601.
[0025] Example 2, based on Example 1, combined with... Figures 5-6As shown, a controller 101 is fixed to the top of the ground 1. The controller 101 is used to control the entire device. A power supply 102 is fixed to the left end of the controller 101, which provides the necessary power to the entire device. Several support rods 201 are fixed to the top of the ground 1. The support rods 201 are made of alloy material and are used to support the screening box 2. The top of each support rod 201 is fixedly connected to the screening box 2. A three-stage channel 202 is fixed to the bottom of the funnel 205. The three-stage channel 202 is made of alloy material and provides a movement path for the coal gangue that leaks through the secondary screening plate 601. The sieve plate positioning shaft 602 is fixedly connected to the first-stage sieve plate 6 and the second-stage sieve plate 601 on its inner side. Two sets of inner locking buckles 502 are also fixed inside the sieve box 2. These inner locking buckles 502 are made of alloy material and prevent the replacement plate 4 from rotating excessively. Each set of inner locking buckles 502 is tightly fitted to the replacement plate 4 on its outer side. Two outer locking buckle motors 5 are also fixed at the front end of the sieve box 2. These motors can drive the outer locking buckles 501 to rotate. Each outer locking buckle motor 5 is rotatably connected to the outer locking buckle 501 on its rear side via a rotating shaft. Each outer locking buckle 501 is tightly fitted to the replacement plate 4 on its rear side. Each outer locking buckle 501 is tightly fitted to the replacement plate 4 on its rear side. The sieve plate positioning shaft 602 is externally connected to a connecting pipe 704 via a shaft pin 703. The connecting pipe 704 and the shaft pin 703 allow the sieve plate positioning shaft 602 to be detached from the vibrating screen auxiliary head 702. Each connecting pipe 704 is fixedly connected to the vibrating screen auxiliary head 702 at its front end. Each vibrating screen main head 7 is rotatably connected to a vibrating screen main head motor 701 at its rear end. The vibrating screen main head motor 701 can drive the vibrating screen main head 7 to rotate. Each vibrating screen main head motor 701 is fixedly connected to the sieve box 2. Two replacement motors 402 are also fixedly fixed at the right end of the sieve box 2. The replacement motors 402 can drive the replacement head 401 to rotate, thereby driving the replacement plate. 4. Rotation facilitates the disassembly of the primary screening plate 6 and the secondary screening plate 601. Each replacement motor 402 is rotatably connected to the replacement head 401 at its left end via a rotating shaft. Each screening plate positioning shaft 602 at both ends is tightly fitted to the stabilizing block 802 at its top. A stabilizing rod 801 is fixed to the top of each stabilizing block 802. The stabilizing rod 801 is used to position the stabilizing block 802. Each stabilizing rod 801 is slidably connected to the spring plate 8 outside it. A stabilizing spring 803 is also provided outside each stabilizing rod 801. The stabilizing spring 803 is elastic, thereby making the stabilizing block 802 tightly fitted to the screening plate positioning shaft 602.
[0026] When using this device, the operator changes the primary screening plate 6 and the secondary screening plate 601 according to the required size of the coal gangue to be screened. The controller 101 then controls the replacement motor 402 to rotate the replacement head 401, which in turn rotates the replacement plate 4, causing it to fit tightly against the inner locking buckle 502. The controller 101 then controls the outer locking buckle motor 5 to rotate the outer locking buckle 501, causing it and the inner locking buckle 502 to lock the replacement plate 4. This allows the screening plate positioning shaft 602 to insert into the positioning hole 403, ensuring the stability of the primary and secondary screening plates 601. At this point, the controller 101 controls the connecting rod 302 to retract, causing the baffle 3 to descend, sealing the primary channel 203 and the secondary channel 204. The conveyor then transports the coal gangue to... The top of the screening box 2 allows coal gangue to fall into the screening box 2. At this time, the controller 101 controls the two main vibrating screen motors 701 to work, thereby driving the two main vibrating screen heads 7 to rotate, which in turn drives the main vibrating screen motors 701 to rotate, thereby driving the auxiliary vibrating screen head 702 to vibrate up and down, thereby causing the primary screening plate 6 and the secondary screening plate 601 to vibrate up and down, thus shaking the coal gangue smaller than the through holes on the primary screening plate 6 and the secondary screening plate 601 to the bottom of the primary screening plate 6 and the secondary screening plate 601. At this time, the workers place multiple conveyors at the left end of the secondary channel 204, the primary channel 203, and the tertiary channel 202. At this time, the controller 101 controls the baffle moving rod 303 to extend, thereby driving the connecting rod 302 to rise, thereby driving the baffle 3 to rise, so that the screened coal gangue is transported synchronously, thereby ensuring the conveying effect of coal gangue.
[0027] The working process of this utility model is as follows: When using this device, the operator changes the primary screening plate 6 and the secondary screening plate 601 according to the required size of the coal gangue to be screened. The controller 101 then controls the replacement motor 402 to rotate the replacement head 401, which in turn rotates the replacement plate 4, causing it to fit tightly against the inner locking buckle 502. The controller 101 then controls the outer locking buckle motor 5 to rotate the outer locking buckle 501, causing it and the inner locking buckle 502 to lock the replacement plate 4. This allows the screening plate positioning shaft 602 to insert into the positioning hole 403, ensuring the stability of the primary screening plate 6 and the secondary screening plate 601. At this time, the controller 101 controls the connecting rod 302 to retract, causing the baffle 3 to descend, thus sealing the primary channel 203 and the secondary channel 204. The conveyor then... Coal gangue is conveyed to the top of the screening box 2, causing it to fall into the screening box 2. At this time, the controller 101 controls the two main vibrating screen motors 701 to work, thereby driving the two main vibrating screen heads 7 to rotate, which in turn drives the main vibrating screen motors 701 to rotate, thereby driving the auxiliary vibrating screen head 702 to vibrate up and down, which in turn causes the primary screening plate 6 and the secondary screening plate 601 to vibrate up and down, thereby separating materials smaller than those on the primary screening plate 6 and the secondary screening plate 601. The coal gangue through the upper through hole 01 is shaken down to the bottom of the primary screening plate 6 and the secondary screening plate 601. At this time, the workers place multiple conveyors at the left end of the secondary channel 204, the primary channel 203 and the tertiary channel 202. The controller 101 controls the baffle moving rod 303 to extend, thereby driving the connecting rod 302 to rise, thereby driving the baffle 3 to rise, so that the screened coal gangue is transported synchronously, thus ensuring the conveying effect of coal gangue.
