Description

Technical Field

[0002] The forked hopper is an important equipment widely used in various industrial scenarios, especially in the loading and unloading of bulk materials in ports, mines and large power stations. It is mainly used in large loading and unloading machinery and equipment such as bucket wheel stackers and reclaimers, and is suitable for continuous operation of bulk materials such as coal, coke and ore.

[0003] For example, a hopper with an ore falling buffer device proposed in announcement No. CN201140877 includes a hopper body, an ore feeding belt is provided above its upper opening, and an ore belt conveying mechanism is provided below the lower opening.

[0004] At present, in the process of ore dropping, as the ore is continuously dropped, since the ore needs to be guided and fed through the first drop plate and the second drop plate, ore accumulation will occur at the first drop plate and the second drop plate, resulting in slow dropping, and in severe cases, blockage of the three-way chute; in addition, after the first drop plate and the second drop plate are switched from the integral type to the split type, the ore is dropped. As the ore is continuously dropped, if ore accumulation occurs, part of the ore will be stuck at the intersection of the second drop plate and the partition, and there will be certain obstacles in the process of the second drop plate being turned back to the integral type. If the hardness of the ore is relatively large, long-term use will cause damage to the second drop plate; and in the process of dropping, some ores have certain adhesion. After continuous dropping, they adhere to the drop plate. If they are not cleaned in time, they will be mixed in when other minerals are dropped later, which will have a certain impact.

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with specific embodiments.

[0021] In order to solve the problem that in the process of ore dropping, as the ore is continuously dropped, the ore needs to be guided and fed through the first drop plate 2 and the second drop plate 3, and ore will accumulate at the first drop plate 2 and the second drop plate 3, causing slow dropping and serious blockage of the three-way chute 1, such as Figure 1 - Figure 7 As shown: A forked material dropping hopper flap, including a three-way chute 1, the three-way chute 1 is a prior art, that is, a pipeline has three openings, when in use, ore enters through the upper opening, and then according to the specific material distribution situation, the ore is selectively fed along the other two openings, the inner side wall of the three-way chute 1 is fixedly connected to a first material dropping plate 2, the side wall of the first material dropping plate 2 is fixedly connected to a partition 4, the side wall of the partition 4 is rotatably connected to a rotating member 21, the side wall of the rotating member 21 is fixedly connected to a second material dropping plate 3, the first material dropping plate 2 is fixed inside the three-way chute 1, the second material dropping plate 3 is flipped by the rotating member 21, and is in a crossed state, so that the original single-line docking production line can be transformed into a double-line operation, so that the material taking operation can reach full load operation, and the bottom end of the first material dropping plate 2 is fixedly installed with a dredging The clearing component 5 is provided with the clearing component 5, and the electromagnet 54 is energized to generate a magnetic pole, and the generated magnetic repulsion force is used to push the mounting plate 52 away from the first blanking plate 2. After the mounting plate 52 moves a certain distance along the sliding rod 51, the electromagnet 54 is powered off, and the electromagnet 54 loses its magnetism and contracts under the elastic action of the first spring 53, pulling the mounting plate 52 to reset and move, so that the impact block 56 impacts the bottom end of the first blanking plate 2. The above steps are repeated continuously, and the impact block 56 continuously impacts the first blanking plate 2, so that the first blanking plate 2 and the surrounding ore are vibrated, and under the action of the gravity of the ore, the downward flow of the ore is accelerated, thereby accelerating the blanking, effectively alleviating the occurrence of ore blockage, and improving the efficiency of ore blanking.

[0022] An auxiliary component 6 is installed inside the partition 4. By setting the auxiliary component 6, before the second blanking plate 3 is rotated, the first electric push rod 62 is started, and the movable end of the first electric push rod 62 drives the moving block 63 to start extending until the top block 68 of the side wall of the moving block 63 moves to the outside of the mounting groove 61. During this process, the top block 68 will gradually pop out under the elastic action of the inclined surface 69 at its bottom and the second spring 66, and the popped-out top block 68 is used to eject the ore stuck at the intersection of the second blanking plate 3 and the partition 4; wherein the distance that the top block 68 moves along the inclined surface 69 is greater than the distance from the inner wall of the mounting groove 61 to the adjacent side wall of the second blanking plate 3, so that the top block 68 is sufficient to move to the bottom of the second blanking plate 3 to eject the stone stuck at the intersection; by ejecting the crushed stone at the intersection of the second blanking plate 3 and the partition 4, damage caused by the crushed stone during the rotation of the second blanking plate 3 is avoided.

[0023] The side walls of the first blanking plate 2 and the second blanking plate 3 are both installed with a scraper assembly 7. By setting the scraper assembly 7, when the first blanking plate 2 and the second blanking plate 3 are in an integrated blanking state, the second electric push rod 74 and the third electric push rod 76 are started, and the corresponding first scraper 75 and the second scraper 77 are driven by the movable ends of the second electric push rod 74 and the third electric push rod 76 to extend along the surfaces of the first blanking plate 2 and the second blanking plate 3 respectively, and the ore adhered to the surfaces of the first blanking plate 2 and the second blanking plate 3 is scraped off to make it fall off. On the one hand, the residual ore is scraped off to avoid ore waste, and on the other hand, it is effective This avoids mixing of different ores during subsequent blanking, thereby improving the practicality of the device. When performing split blanking, the position of the first blanking plate 2 remains unchanged, while the second blanking plate 3 rotates and uses the back plate to divide the material. At this time, the back plate is adhered to the ore. After the blanking is completed, the ore removal method on the surface of the first blanking plate 2 is consistent with the integral type, while the second blanking plate 3 starts the fourth electric push rod 78 and uses the interactive end of the fourth electric push rod 78 to drive the third scraper 79 to move along the back plate of the second blanking plate 3 to scrape off the adhered ore and make it fall, thereby improving the use effect of the device.

[0024] The dredging assembly 5 includes a plurality of slide bars 51 , each of which is fixedly connected to the bottom end of the first blanking plate 2 , and the plurality of slide bars 51 are slidably connected to a mounting plate 52 , and a first spring 53 is fixedly connected to the bottom end of the first blanking plate 2 .

[0025] One end of each first spring 53 is fixedly connected to the top of the mounting plate 52, and each first spring 53 is sleeved on the side wall of the adjacent slide rod 51. A plurality of impact blocks 56 are symmetrically fixedly connected to the top of the mounting plate 52. An electromagnet 54 is fixedly connected to the bottom end of the first blanking plate 2, and a permanent magnet 55 is fixedly connected to the top of the mounting plate 52. The electromagnet 54 and the permanent magnet 55 are located in the same vertical plane.

[0026] In this scheme: when the ore is discharged slowly, the electromagnet 54 is energized to generate magnetic poles, wherein the electromagnet 54 and the permanent magnet 55 generate the same magnetic poles, and the generated magnetic repulsion force is used to push the mounting plate 52 away from the first blanking plate 2. At this time, the first spring 53 is in a stretched state. After the mounting plate 52 has moved a certain distance along the slide bar 51, the electromagnet 54 is powered off, and the electromagnet 54 loses its magnetism, so that the magnetic repulsion force between the electromagnet 54 and the permanent magnet 55 disappears, and the electromagnet 54 contracts under the elastic action of the first spring 53, pulling the mounting plate 52 to reset and move, so that the impact block 56 impacts the bottom end of the first blanking plate 2, and the above steps are repeated continuously. The impact block 56 continuously impacts the first blanking plate 2, so that the first blanking plate 2 and the surrounding ore are vibrated, and under the action of the gravity of the ore, the ore flows downward faster, thereby accelerating the blanking, effectively alleviating the occurrence of ore blockage, and improving the efficiency of ore blanking; The initial position of the impact block 56 is in contact with the bottom of the first blanking plate 2, so that the displacement generated during the power-on and power-off process of the electromagnet 54 is sufficient to impact the first blanking plate 2, speeding up the ore discharge, alleviating the problems of slow discharge and ore blockage. In addition, the electromagnet 54 is generally not used, and is only powered on and used when the discharge is slow.

[0027] In order to solve the problem that after the first blanking plate 2 and the second blanking plate 3 are switched from the integral type to the split type, the materials are blanked. As the ore is continuously discharged, if ore accumulation occurs, part of the ore is stuck at the intersection of the second blanking plate 3 and the partition 4, and there is a certain obstacle in the process of the second blanking plate 3 being turned back to the integral type, if the hardness of the ore is large, the second blanking plate 3 will be damaged after long-term use, such as Figure 8 - Fig.15 As shown: The auxiliary component 6 includes a mounting groove 61 , which is opened at the top of the partition 4 and is an inverted convex structure. A first electric push rod 62 is fixedly connected to the bottom wall of the mounting groove 61 , and a moving block 63 is fixedly connected to the movable end of the first electric push rod 62 .

[0028] The moving block 63 is slidably connected to the inner wall of the installation groove 61. The moving block 63 is slidably connected to the inner wall of the installation groove 61. Two sliding grooves 64 are opened on the side wall of the moving block 63. Each sliding groove 64 has a groove body 65 on the inner wall. The second spring 66 is fixedly connected to the inner wall of the groove body 65.

[0029] One end of the second spring 66 is fixedly connected to a connecting block 67, which is embedded and slidably connected to the inside of the groove body 65. The side wall of the connecting block 67 is fixedly connected to a top block 68, which slides against the inner wall of the installation groove 61, and a slope 69 is provided at the bottom end of the top block 68.

[0030] In this solution: after the split-type material unloading is completed, the second blanking plate 3 needs to be rotated to the integrated type. In order to avoid ore blockage at the first blanking plate 2 and the second blanking plate 3 during material unloading, some ores are stuck between the second blanking plate 3 and the partition plate 4. Directly rotating the second blanking plate 3 will cause damage; before rotating the second blanking plate 3, start the first electric push rod 62, and the movable end of the first electric push rod 62 drives the moving block 63 to start extending until the top block 68 of the side wall of the moving block 63 moves to the outside of the mounting groove 61. During this process, the top block 68 will gradually pop out under the elastic action of the inclined surface 69 at its bottom and the second spring 66, and the popped-up top block 68 will be used to hold the card The ore is ejected at the intersection of the second blanking plate 3 and the partition plate 4; the initial position of the moving block 63 is located inside the mounting groove 61, at which time the second spring 66 is in a compressed state, and when the top block 68 begins to move to the outside of the mounting groove 61, a portion of the inclined surface 69 at the bottom of the top block 68 is always left to facilitate subsequent reset and movement to the inside of the mounting groove 61. In addition, the distance that the top block 68 moves along the inclined surface 69 is greater than the distance from the inner wall of the mounting groove 61 to the adjacent side wall of the second blanking plate 3, so that the top block 68 is sufficient to move to the bottom of the second blanking plate 3 to eject the stone stuck at the intersection; and the connecting block 67 is always located inside the slot body 65, so that the second spring 66 will not leave the inside of the slot body 65; After the gravel at the intersection of the second blanking plate 3 and the partition 4 is pushed out, the first electric push rod 62 drives the moving block 63 to start to retract. During the resetting movement, since a section of the bottom wall of the top block 68 is always located inside the mounting groove 61, the top block 68 starts to move along the inclined surface 69 for resetting. When the moving block 63 is reset to the initial position, the top block 68 compresses the second spring 66 and all enters the slide groove 64, preventing the top block 68 from limiting the second blanking plate 3 and affecting the rotation.

[0031] In order to solve the problem that some ores are sticky during the blanking process, they will stick to the blanking plate after continuous blanking. If they are not cleaned in time, other minerals will be mixed in when they are blanked later, which will have certain impacts, such as Fig.16 - Fig.18 As shown: The scraper assembly 7 includes a first protective box 71, which is fixedly connected to the top of the first blanking plate 2. A wedge block 73 is fixedly connected to the side wall of one end of the first protective box 71. The side wall of the wedge block 73 is in contact with the inner wall of the three-way slide pipe 1. The inner wall of the first protective box 71 is symmetrically fixedly connected to a second electric push rod 74.

[0032] The movable end of the second electric push rod 74 passes through the side wall of the first protective box 71 and is fixedly connected to the first scraper 75. The first scraper 75 is a wedge-shaped structure. The bottom end of the first scraper 75 is in contact with the top end of the first blanking plate 2. The top and bottom ends of the second blanking plate 3 are fixedly connected to the second protective box 72.

[0033] A third electric push rod 76 is fixedly connected to the inner wall of one of the second protective boxes 72, and the movable end of the third electric push rod 76 passes through the adjacent side wall of the second protective box 72 and is fixedly connected to the second scraper 77. A fourth electric push rod 78 is fixedly connected to the inner wall of the other second protective box 72, and the movable end of the third electric push rod 76 passes through the adjacent side wall of the second protective box 72 and is fixedly connected to the third scraper 79.

[0034] In this scheme: when the first blanking plate 2 and the second blanking plate 3 are in the integrated blanking, for some ores that may adhere, after the material separation is completed, in order to avoid mixing in other ores in the subsequent blanking process; start the second electric push rod 74 and the third electric push rod 76, through the movable ends of the second electric push rod 74 and the third electric push rod 76, drive the corresponding first scraper 75 and the second scraper 77 to extend along the surfaces of the first blanking plate 2 and the second blanking plate 3 respectively, and when the first scraper 75 and the second scraper 77 move to the edge position of the first blanking plate 2 and the second blanking plate 3, they begin to shrink, and by reciprocating the first scraper 75 and the second scraper 77, the ores adhered to the surfaces of the first blanking plate 2 and the second blanking plate 3 are scraped off and dropped. On the one hand, the residual ore is scraped off to avoid ore waste, and on the other hand, it is effectively avoided that different ores are mixed in when they are blanked in the subsequent time, thereby improving the practicality of the device; When split blanking is performed, the position of the first blanking plate 2 remains unchanged, and the second blanking plate 3 rotates and uses the back plate to divide the material. At this time, the back plate is adhered to the ore. When the blanking is completed, the ore removal method on the surface of the first blanking plate 2 is consistent with the integral type, and the second blanking plate 3 starts the fourth electric push rod 78 and uses the interactive end of the fourth electric push rod 78 to drive the third scraper 79 to move along the back plate of the second blanking plate 3 to scrape the adhered ore and make it fall, thereby improving the use effect of the device.
