Description

Technical Field

[0001] The invention relates to the technical field of mineral processing, and in particular to a mineral conveying device and a conveying method with protection. Background Art

[0002] Mineral conveying equipment plays a vital role in mining production. They are responsible for transporting materials such as ore, coal, and rock from the mining site to the processing or storage site. The equipment usually uses conveyors to transport minerals.

[0003] When existing conveying devices transport materials, the materials will be directly piled on the conveyor through the feed hopper. Due to the uneven distribution of materials on the conveyor belt, materials sticking to the conveyor belt, and improper tightness of the conveyor belt, the conveyor belt will deviate. In addition, during transportation, wind will blow the materials and cause them to fall, posing a safety hazard to the operator.

[0004] The reason for this problem is that, currently materials are directly accumulated on the conveyor belt through the feed hopper, which will damage the conveyor belt and cause uneven distribution of materials on the conveyor belt, resulting in a phenomenon of heavy one side and light one side, causing the conveyor belt to shift, and part of the water-containing material will stick to the conveyor belt, which will also cause the conveyor belt to shift, and the conveyor adjusts the tightness of the conveyor belt by changing the position of the adjusting roller, but the existing fixing method is a single-sided bolt fixing, which makes it impossible to ensure that the two sides are parallel and the adjustment is also more troublesome, causing the conveyor belt to shift due to inappropriate tightness. Since the size, shape, and density of the material itself are different, when it is blown by the wind, its falling range will also change, and the fixed protective net cannot ensure the safety of the operator. Therefore, in view of the shortcomings of the existing technology, we propose a protective mineral conveying device and conveying method to solve the above problems. Summary of the invention

The anti-deviating mechanism 5 includes a guide block 501, a transmission member 502, a U-shaped block 503, a support rod 504 and a scraper 505;

[0042] The guide block 501 is fixedly installed inside the feed hopper 3, and multiple groups of transmission members 502 are fixedly installed at the top of the machine body 1 at equal intervals. The top of the transmission member 502 is against the bottom of the conveyor belt 2, and the support rod 504 is fixedly installed at both ends of the machine body 1. The U-shaped block 503 is slidably connected to the inside of the machine body 1, and the U-shaped block 503 is rotatably connected to the adjusting roller 4. The scraper 505 is rotatably connected to one side of the machine body 1.

By adjusting the angle of the scraper 505, it can adapt to conveyor belts 2 of different widths, so that it can effectively scrape off the materials adhering to the conveyor belt 2, and will not directly contact the conveyor belt 2 to avoid damaging the outer surface of the conveyor belt 2.

[0043] Anti-dropping parts 6 are provided on both sides of the machine body 1 .

[0044] The transmission member 502 includes a horizontal plate 5021, a side column 5022 and a column 5023;

By using the side rollers 5024 and the center roller 5025, the conveyor belt 2 is U-shaped, and by cooperating with the guide block 501 inside the feed hopper 3, it can be ensured that the material is always in the middle of the conveyor belt 2, and the phenomenon of one side of the conveyor belt 2 being heavy and the other side being light will not occur, thereby ensuring that the conveyor belt 2 will not be offset.

[0046] The transmission member 502 is provided with a shock absorbing member 506 inside, and the shock absorbing member 506 includes a push rod 5061, a fixing ring 5062 and a sleeve 5064; the push rod 5061 is rotatably connected to one side of the side column 5022, and the sleeve 5064 is rotatably connected to the inside of the cross plate 5021, and the push rod 5061 is movably clamped in the inside of the sleeve 5064, and the fixing ring 5062 is fixedly installed on one side of the push rod 5061. The sleeve 5064 and the push rod 50 61. The spring 5063 and the rubber sheet 5065 together form the effect of a damper. The force pushes the push rod 5061 on one side of the side column 5022 into the sleeve 5064. The rubber sheet 5065 at the end of the push rod 5061 is against the inner wall of the sleeve 5064, and the force is dissipated into invisibility through friction. The spring 5063 pushes the push rod 5061 back to its original position to achieve uninterrupted buffering of the material, thereby alleviating the impact of the material on the belt and the conveyor.

[0047] The shock absorber 506 also includes a spring 5063 and a rubber sheet 5065; the spring 5063 is wound on the outer surface of the push rod 5061, one end of the spring 5063 is fixedly connected to the fixing ring 5062, and the other end of the spring 5063 is fixedly connected to the sleeve 5064, and the rubber sheet 5065 is fixedly installed on the end of the push rod 5061, and the rubber sheet 5065 is against the inner wall of the sleeve 5064.

[0048] The U-shaped block 503 is fixedly connected with fixing bars 507 on both sides, and the ends of the fixing bars 507 are threadedly connected with fixing bolts 508, and the bottom of the fixing bolts 508 is against the support rod 504. A push-pull cylinder 509 is fixedly installed inside the body 1, and the output shaft of the push-pull cylinder 509 is fixedly connected to the U-shaped block 503. The push-pull cylinder 509 pushes upward to relax the conveyor belt 2, and the push-pull cylinder 509 slides downward to tighten the conveyor belt 2. The fixing bars 507 on both sides of the U-shaped block 503 slide on the outer surface of the support rod 504, providing a guide for the sliding of the entire U-shaped block 503 so that its position will not shift. When it is adjusted to a suitable tightness of the current conveyor belt 2, the push-pull cylinder 509 is stopped and the fixing bolts 508 are tightened to evenly distribute the weight of the adjusting roller 4 and the U-shaped block 503 on the body 1, thereby avoiding the push-pull cylinder 509 from being subjected to excessive pressure, thereby increasing the service life of the conveyor in disguise.

[0049] A discharge hopper 510 is fixedly installed on the other side of the body 1, and a rotating shaft 511 is rotatably connected to one side of the body 1. The scraper 505 is fixedly connected to the rotating shaft 511, and a fixing plate 512 is fixedly connected to one side of the rotating shaft 511. The internal thread of the fixing plate 512 is connected to a fixing screw 513, and the bottom of the fixing screw 513 is against the body 1. One end of the discharge hopper 510 is higher. The material hits the discharge hopper 510 and is blocked by the discharge hopper 510. It falls vertically under the influence of gravity, so that the landing point of the material can be controlled and the material can be collected more accurately.

[0050] The anti-falling member 6 includes a threaded rod 601, a support plate 602, a support bar 603, an anti-falling net 604 and a slider 605;

[0051] The threaded rod 601 is rotatably connected to the inside of the support rod 504, and multiple groups of support strips 603 are fixedly connected to one side of the support plate 602. One end of the anti-falling net 604 is fixedly connected to the support plate 602, and the other end of the anti-falling net 604 is fixedly connected to the end of the support strip 603. A slider 605 is fixedly connected to the other side of the support plate 602. The slider 605 is threadedly connected to the threaded rod 601, and the support plate 602 is slidably connected to the outer surface of the support rod 504. The anti-dropping member 6 also includes a first bevel gear 606, a second bevel gear 607 and a motor 608; the first bevel gear The wheel 606 is fixedly connected to the bottom of the threaded rod 601, the second bevel gear 607 is movably engaged with the first bevel gear 606, the motor 608 is fixedly installed on one side of the support rod 504, and the output shaft of the motor 608 is fixedly connected to the second bevel gear 607. When the wind is strong, the material will be blown up by the wind, but different materials have different characteristics, and their sizes, shapes, and densities are different, so that their falling range will also change. By adjusting the anti-dropping part 6, the fallen materials can be effectively collected, which ensures the safety of the operator and has high practical value.

[0052] In summary, compared with the prior art, the present invention has the following beneficial effects: the device puts the material into the feed hopper 3, and the conveyor belt 2 is impacted by the material, so that the side column 5022 rotates inward, and the force pushes the push rod 5061 on one side of the side column 5022 into the sleeve 5064, and the rubber sheet 5065 at the end of the push rod 5061 is against the inner wall of the sleeve 5064, and the force is dissipated into invisibility through friction, and the spring 5063 pushes the push rod 5061 back to its original position to achieve uninterrupted buffering of the material, and the guide block 501 inside the feed hopper 3 cooperates with the side rollers 5024 and the center roller 5025, so that the conveyor belt 2 presents a U shape, thereby causing the material to be conveyed. When the conveyor belt 2 is conveying, it can be kept in the middle of the conveyor belt 2, and the conveyor belt 2 will not be offset. The scraper 505 is rotated on one side of the body 1 through the rotating shaft 511. The end of the rotating shaft 511 is fixedly connected with a fixing plate 512, which is threaded with a fixing screw 513. The bottom of the fixing screw 513 is against the body 1. The angle of the scraper 505 can be adjusted by rotating the rotating shaft 511. The scraper 505 is fixed by the fixing screw 513. By adjusting the angle of the scraper 505, it can adapt to conveyor belts 2 of different widths. When the material is discharged through the discharge hopper 510, the material directly hits the inner wall of the discharge hopper 510 and is affected by gravity. The material falls into the collecting device under the influence of the material discharge position limited by the discharge hopper 510, so that the material can be collected more accurately. When the tightness of the conveyor belt 2 needs to be adjusted, the push-pull cylinder 509 is started to drive the U-shaped block 503 to slide up and down, thereby driving the adjusting roller 4 to slide up and down, and the push-pull cylinder 509 is pushed upward to loosen the conveyor belt 2, and the push-pull cylinder 509 slides downward to tighten the conveyor belt 2. The fixed bars 507 on both sides of the U-shaped block 503 slide on the outer surface of the support rod 504. When the anti-falling net 604 needs to be adjusted downward according to the type of material, the motors 608 on both sides are started at the same time, and the motor 608 rotates forward. The output shaft is fixedly connected to the second bevel gear 607, so that when the second bevel gear 607 rotates, it drives the first bevel gear 606 to rotate, so that the threaded rod 601 also rotates. When the threaded rod 601 rotates, the slider 605 at the end of the support plate 602 slides downward, driving the entire anti-drop component 6 to slide downward. When the anti-drop component 6 needs to be adjusted upward, the motor 608 reverses, driving the threaded rod 601 to reverse, so that the slider 605 at the end of the support plate 602 slides upward, driving the entire anti-drop component 6 to slide upward. By starting the forward and reverse rotation of the motor 608, the height of the entire anti-drop component 6 can be adjusted. The adjustment is simple and meets the needs of users.
