Description

Technical Field

[0001] The invention relates to the technical field of conveyors, and in particular to a crawler mobile conveyor with a dust suppression function. Background Art

[0002] Conveyors are highly maneuverable, easy to transport, and flexible in conveying angle and height adjustment. Whether it is loading ore or conveying and transferring ore in crushing and screening operations, conveyors can be flexibly involved to reduce the use of on-site scraper equipment. Among them, before the ore is transported to the crusher for crushing, since there may be tree roots, plant branches and other debris in the ore and sand, the workers need to remove the larger tree roots first. However, the tree roots are mixed in the ore, and under the influence of the gravity of the ore, it is difficult to remove them. When there are multiple tree roots at the same time, it is difficult to remove them all manually. Alternatively, after the crusher crushes the tree roots, its fibers and residues are removed.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Example 1: Please refer to Figures 1 to 6 The present invention provides a technical solution: a crawler mobile conveyor with dust suppression function, comprising a traveling mechanism 1, a folding mechanism 11, a conveying mechanism 12 and an upper hopper 13, wherein the folding mechanism 11 is fixedly mounted above the traveling mechanism 1, the conveying mechanism 12 is fixedly mounted on the folding mechanism 11, the upper hopper 13 is located at one end of the conveying mechanism 12, and a pre-screening component is arranged on the upper hopper 13, and the pre-screening component is used to improve the conveying effect; The pre-screening assembly includes a screening box 2, which is fixedly mounted in the inner cavity of the upper hopper 13, a first servo motor 21 is fixedly mounted on the surface of the upper hopper 13, a first rotating shaft 22 is fixedly mounted on the output shaft of the first servo motor 21, a selection claw 23 is fixedly sleeved on the outer surface of the first rotating shaft 22, a holding box 24 is fixedly mounted on one side of the upper hopper 13, and a hinged door 25 is hingedly connected to the side of the holding box 24 away from the upper hopper 13; The outer surface of the output shaft of the first servo motor 21 is fixedly sleeved with a first rotating wheel 26, the outer surface of the first rotating wheel 26 is drivingly connected to a first transmission belt 27, the end of the first transmission belt 27 away from the first rotating wheel 26 is drivingly connected to a second rotating wheel 28, a turning frame 29 is fixedly installed in the middle of the second rotating wheel 28, the turning frame 29 is movably installed on the outer surface of the containing box 24, and a pressing block 210 is fixedly installed in the middle of the turning frame 29.

[0018] Specifically, when in use, the conveyor needs to be moved to the stone pile, and then the conveying mechanism 12 is unfolded by the folding mechanism 11, and the upper hopper 13 is placed close to one end of the stone pile, and the other end of the conveyor needs to be placed directly above the upper hopper of the crusher, and then an excavator or other loading machine is used to put the stone into the upper hopper 13, and the stone is transported to the crusher by the conveying mechanism 12 for crushing; When the stone enters the upper hopper 13, it will first fall onto the surface of the screening box 2. At this time, the smaller stone will pass through the screening slot far away from the containing box 24 and fall onto the conveying mechanism 12 to be conveyed, while the larger stone will fall close to the screening slot of the containing box 24. After the stone falls, the first servo motor 21 needs to be started to drive the first rotating shaft 22 to rotate, so that the first rotating shaft 22 drives the picking claw 23 to rotate. The picking claw 23 can be used to preliminarily remove impurities such as roots and branches with longer lengths in the stone. With the continuous rotation of the picking claw 23, the impurities such as roots and branches will be introduced into the inner cavity of the containing box 24 to complete the preliminary impurity removal. When the impurities such as roots and branches in the stone are reduced, the dust generated by the movement of impurities such as roots and branches during the stone transportation can also be reduced. When the first servo motor 21 is started, it will drive the first rotating wheel 26 to rotate, so that the first rotating wheel 26 drives the first transmission belt 27. The first transmission belt 27 can drive the second rotating wheel 28 to rotate, so that the second rotating wheel 28 drives the flip frame 29 and the pressing block 210 to flip, so that impurities such as tree roots and branches can smoothly enter the inner cavity of the containing box 24. When the picking claw 23 is reset, the flip frame 29 and the pressing block 210 will follow the reset. When the impurities such as tree roots and branches in the inner cavity of the containing box 24 increase, the pressing block 210 can be used to squeeze from the top to compress the impurities, thereby increasing the impurity capacity of the containing box 24 and reducing the number and frequency of cleaning by the staff.

[0019] Example 2: Please refer to Figures 3 to 7 , a trimming assembly is provided on the upper hopper 13, and the trimming assembly includes a trimming module and a compacting module; The trimming module includes a second servo motor 3 fixedly mounted on the surface of the upper hopper 13, a third rotating wheel 31 is fixedly sleeved on the outer surface of the output shaft of the second servo motor 3, a second transmission belt 32 is transmission-connected to the outer surface of the third rotating wheel 31, an end of the second transmission belt 32 away from the third rotating wheel 31 is transmission-connected to the fourth rotating wheel 33, a trimming roller 34 is fixedly mounted in the middle of the third rotating wheel 31, a first grinding roller 35 is fixedly mounted in the middle of the fourth rotating wheel 33, and the trimming roller 34 and the first grinding roller 35 are both located below the screening box 2; A mounting box 36 is fixedly installed on one side of the upper hopper 13, and support columns 37 are fixedly installed on both sides of the inner cavity of the mounting box 36. A limit block 38 is fixedly installed on one end of the support column 37 away from the mounting box 36, and a return spring 39 is sleeved on the outer peripheral side of the support column 37. A bracket 310 is movably installed on the outer surface of the support column 37, a trimming plate 311 is fixedly installed on the upper side of the surface of the bracket 310, and a mounting frame 312 is fixedly installed on the lower side of the surface of the bracket 310. A second grinding roller 313 is movably installed on the inner side of the mounting frame 312, and a resistance spring 314 is fixedly connected to the side of the trimming plate 311 away from the trimming roller 34, and one end of the resistance spring 314 away from the trimming plate 311 is fixedly connected to the surface of the mounting box 36, and a spring piece 315 is fixedly installed on the bottom of the screening box 2; The compaction module includes a fixed block 316, which is fixedly mounted on the top of the bracket 310. A push plate 317 is fixedly mounted on the top of the fixed block 316. The push plate 317 is located in the inner cavity of the containing box 24. A push groove 318 adapted to the fixed block 316 is provided at the bottom of the containing box 24. The spring piece 315 is composed of an upper baffle and a lower elastic metal sheet. Screen slots are provided on both sides of the screening box 2. The width of the screen slot close to the containing box 24 is greater than the width of the screen slot away from the containing box 24. The diameter of the limit block 38 is greater than the diameter of the support column 37 . One end of the return spring 39 is fixedly connected to the inner cavity of the installation box 36 , and the other end of the return spring 39 is fixedly connected to the bracket 310 .

[0020] On the basis of Example 1, when the stone falls through the sieve slot near the side of the containing box 24, it is necessary to start the second servo motor 3 to drive the trimming roller 34 to rotate, and use the sharp cone on the surface of the trimming roller 34 and the saw teeth on the surface of the trimming plate 311 to trim the surface of the stone with a larger volume, break its sharp parts, and prevent it from falling to the surface of the conveying mechanism 12 and causing wear to the conveying mechanism 12 under the influence of potential energy; Furthermore, when the second servo motor 3 is started, the third rotating wheel 31 is driven to rotate, so that the third rotating wheel 31 drives the second transmission belt 32, and the second transmission belt 32 can drive the fourth rotating wheel 33 to rotate, so that the fourth rotating wheel 33 drives the first grinding roller 35 to rotate, and cooperates with the second grinding roller 313 to grind the stone, and further grind off the sharp part of the broken part, so as to avoid the stone from falling to the conveying mechanism 12 and causing wear to the conveying mechanism 12; When the stone is between the trimming roller 34 and the trimming plate 311, or between the first grinding roller 35 and the second grinding roller 313, as the stone is continuously rotated and guided downward by the trimming roller 34 and the first grinding roller 35, the trimming plate 311 and the second grinding roller 313 are squeezed. The cooperation of the return spring 39 and the resistance spring 314 can increase the resistance to the stone. On the one hand, the sharp part of the stone surface can be broken under the action of the force between the trimming roller 34 and the trimming plate 311. On the other hand, when the resistance spring 314 and the return spring 39 are deformed, the trimming plate 311 and the second grinding roller 313 can be displaced, thereby facilitating the passage of the stone. Furthermore, when the stone falls downward through the first grinding roller 35, it will touch the spring piece 315. The spring piece 315 can block the stone and reduce the potential energy of the stone when it falls to the surface of the upper hopper 13. On the one hand, it can reduce the wear of the conveying mechanism 12 caused by the excessive potential energy of the stone, and on the other hand, it can reduce the noise and dust when the stone falls. On the other hand, when the trimming plate 311 moves, it will drive the fixed block 316 to move in the push groove 318, so that the push plate 317 moves in the inner cavity of the containing box 24, and cooperates with the pressing block 210 to squeeze impurities such as roots and branches into blocks. On the one hand, it can further reduce the distance between impurities and increase the space capacity. On the other hand, the impurities squeezed into blocks are convenient for the staff to handle.

[0021] Example 3: Please refer to Figure 5 , Figure 6 and Figure 8 The upper hopper 13 is provided with a rejection assembly, which includes a third servo motor 4 fixedly mounted on the surface of the upper hopper 13, a second rotating shaft 41 fixedly mounted on the output shaft of the third servo motor 4, a first transmission roller 42 fixedly mounted on one end of the second rotating shaft 41 away from the third servo motor 4, a transmission belt 43 is transmission-connected to the outer surface of the first transmission roller 42, and a second transmission roller 44 is transmission-connected to the other side of the transmission belt 43; A rejecting member 45 is fixedly mounted on the surface of the transmission belt 43, and a rejecting cone 46 is fixedly mounted on one end of the rejecting member 45 away from the transmission belt 43. A first through groove 47 adapted to the transmission belt 43 is formed on the surface of the upper hopper 13, and second through grooves 48 are formed on both upper and lower sides of the first through groove 47. The width of the second through slot 48 above the first through slot 47 is smaller than the width of the second through slot 48 below the first through slot 47, and the rejecting piece 45 and the rejecting cone 46 are both made of aluminum alloy; A helical gear box 5 is fixedly mounted on the outer surface of the second rotating shaft 41 , a flattening piece 51 is fixedly mounted on the output end of the helical gear box 5 , and a third through groove 52 matched with the flattening piece 51 is formed on the surface of the upper hopper 13 .

[0022] On the basis of Example 2, when the large-volume stones are trimmed, they will fall one by one onto the surface of the conveying mechanism 12, thereby preventing the large-volume stones from piling up together, causing the conveying mechanism 12 to be locally overloaded and damaged, and affecting transportation; When the conveying mechanism 12 receives the stones, the third servo motor 4 is started to drive the second rotating shaft 41 to rotate, so that the second rotating shaft 41 drives the helical gear box 5, thereby driving the flattening member 51 to rotate. The flattening member 51 can be used to flatten the piled stones on the surface of the conveying mechanism 12, so that the surface of the conveying mechanism 12 can evenly carry the stones, further avoiding excessive local load on the surface of the conveying mechanism 12; When the second rotating shaft 41 rotates, it can drive the first transmission roller 42 to rotate, thereby driving the transmission belt 43. The transmission belt 43 can drive the removal piece 45 to move. The removal piece 45 and the removal cone 46 can be used to insert the removal cone 46 into the impurities when the stone passes by, or the removal piece 45 drives the impurities to be discharged through the second through groove 48, so that the smaller tree roots and branches can be further removed. The impurities inserted by the removal cone 46 can be removed from the removal cone 46 when the removal piece 45 moves to the second through groove 48 above because the width of the second through groove 48 above is smaller.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
