Description

Technical Field

[0001] The present invention relates to the technical field of mine exploitation, and particularly relates to a chute conveying device for mine exploitation. Background Art

[0002] In mine exploitation operations, in order to facilitate the conveyance of ore from a high place to a low place, a chute is usually adopted. The chute is usually arranged obliquely, and the ore slides down by its own gravity, without the need for additional power, which can reduce energy consumption and improve the ore conveying efficiency. Since the ore is in an irregular shape after exploitation, when using a traditional chute to convey the ore, the ore is prone to jamming and blockage during conveyance in the chute. Therefore, the chute urgently needs to be improved and innovated to meet the development requirements of high efficiency, safety, and environmental protection in modern mine exploitation.

[0003] With the development of technology, technicians in related fields have also carried out a lot of optimization on the chute for mine exploitation. For more accurate comparison, for example, Chinese Patent No. CN220244447U discloses a chute device for open-pit mine exploitation and transportation, including a bench ore storage bin and a transportation chute arranged above the bench ore storage bin. The transportation chute is used to guide the ore to flow into the bench ore storage bin. The bench ore storage bin includes a storage bin body with an opening at the top, a guiding slide plate inclined in the storage bin body, and an outlet chute connected to the outer wall of the storage bin body. The storage bin body is provided with an ore outlet communicating with the outlet chute and can be lifted to open and close the ore outlet.

[0004] When the above-mentioned prior art is in use, the ore is conveyed from the upper bench surface to the bench ore storage bin on this bench surface for storage. When the weight of the ore stored in the bench ore storage bin reaches a preset value, the ore outlet is opened, and the inclined guiding slide plate is used to guide the ore in the bench ore storage bin to slide into the outlet chute through the ore outlet and be conveyed to the next bench surface. At the same time, multiple chute devices for open-pit mine exploitation and transportation are used in combination to realize multi-bench storage and transportation of the stope ore.

[0005] However, the above-mentioned prior art still has some deficiencies in the process of conveying ore:

[0006] 1. The above-mentioned prior art uses multiple bench ore storage bins for multi-bench storage and transportation. However, after the ore is crushed, it is in an irregular shape. Therefore, when the ore is stored in the storage bin body, it is easy to stack, resulting in a certain stability between the ore piles after the outlet chute is opened and the ore cannot be smoothly discharged, thus causing jamming and blockage, and further affecting the ore conveying efficiency.

[0007] 2. Since the ore collides and rubs against the inner wall of the chute device continuously during transportation in the chute, it is easy to exacerbate the wear degree of the chute device. However, the above-mentioned existing technology cannot reduce the impact and friction between the ore and the chute device, resulting in the easy shortening of the service life of the chute device in a harsh environment of severe wear, and further increasing the maintenance and replacement costs.

[0008] 3. In addition, when the ore is transported in the chute, the dust on its surface is likely to fly after being collided, thus reducing the visibility of the working environment and affecting the line of sight of the staff. However, the above-mentioned existing technology cannot effectively reduce the dust, resulting in the dust also affecting the air environment and causing pollution.

[0009] Therefore, under the viewpoints stated above, there is still room for improvement in the existing chute for transporting ore. Summary of the Invention

[0017] As a preferred technical solution of the present invention, mounting holes are formed on both vertical sections of the chute body, two support shafts are symmetrically inserted along the length direction inside the mounting holes, and a conveyor belt for conveying the ore downward is sleeved between the two support shafts.

[0018] As a preferred technical solution of the present invention, a plurality of bump blocks are uniformly installed on the outer wall of the conveyor belt, the thickness of the bump blocks gradually decreases toward the side away from the conveyor belt, a receiving area for pushing the ore is formed between two adjacent bump blocks, and a rotating column is rotatably installed on the side of the bump block away from the conveyor belt.

[0021] In summary, the present application includes the following beneficial technical effects:

[0022] 1. In the present invention, the crankshaft drives the connecting block to move synchronously in the circumferential direction. The connecting block drives the lifting block and the pin shaft to reciprocate up and down. The pin shaft drives the two linkage plates to cycle through the actions of bulging upward and resetting downward. When the linkage plates bulge upward, they can prop up the ore to facilitate the breaking of the ore pile, causing the ore pile to disperse and quickly roll down.

Moreover, the continuously rotating roller can further improve the conveying efficiency of the ore.

[0024] 3.

[0025] 4. In the present invention, through the mutual cooperation among the crankshaft, the driving bevel gear, the linkage bevel gear, the connecting shaft and the support shaft, the conveyor belt can be driven to rotate counterclockwise, so that the conveyor belt drives the dialing block to push down the ore in the vertical section of the chute body. Moreover, the accommodating area between adjacent two dialing blocks can carry the ore and push it down, thereby breaking the jamming and blockage in the vertical section of the chute body and further improving the conveying efficiency of the ore. In addition, the conveyor belt can reduce the wear degree of the vertical section of the chute body.

[0026] 5. In the present invention, the opening at the upper end of the chute body is blocked in the form of water mist to intercept the dust generated during the conveying of the ore, prevent the dust from flying in the air and affecting the environment, and thus ensure the visibility of the working site and the safety of the work.

Detailed implementation manners

[0039] The following will be described in detail with reference to the appended Figure 1-10 embodiments of the present invention.

[0040] The embodiment of the present application discloses a chute conveying device for mining. It should be noted that the chute conveying device for mining of the present application is mainly used in the process of conveying mined ore. In terms of technical effect, it can break up ore piles during the chute body 1 conveying ore, thereby effectively preventing the ore piles caused by jamming and blockage from affecting the conveying efficiency; in addition, it can push the ore at the horizontal and vertical sections of the chute body 1 downward to prevent the ore from being jammed at the upper end of the linkage plate 33 and causing blockage, and can further improve the ore conveying efficiency; further, the chute conveying device for mining of the present application can also intercept the dust generated during the ore conveying by spraying water mist, prevent the dust from flying in the air and affecting the environment, thereby ensuring the visibility of the workplace and the safety of work.

[0041] Embodiment 1:

[0042] Reference Figure 1 and Figure 2 As shown, a chute conveying device for mining includes a chute body 1, one end of which is tilted downward, a support frame 2 is installed at the lower end of the chute body 1, the cross-section of the chute body 1 is a U-shaped structure, the horizontal section of the chute body 1 is installed with a pile-breaking unit 3 for avoiding ore accumulation, and the vertical section of the chute body 1 is provided with a feeding unit 4 for improving the ore conveying efficiency; the pile-breaking unit 3 includes a lifting plate 31 installed at the upper end of the horizontal section of the chute body 1, the lifting plate 31 is composed of two linkage plates 33 hinged to each other by a pin shaft 32, and the lower end of the linkage plate 33 is slidably connected to the chute body 1.

[0043] In the specific implementation process, after the large volume of ore is broken into block ore by the crusher, the ore is transported to the chute body 1 by the conveyor, so that the ore can freely roll down along the inclined chute body 1, so as to realize efficient and safe transportation of the ore; during this period, the ore blocked or accumulated in the chute body 1 can be lifted and dispersed by the pile breaking unit 3, so as to break the ore pile and avoid the phenomenon of jamming, blockage and other phenomena that affect the transportation efficiency; in addition, the feeding unit 4 can cooperate with the pile breaking unit 3 to further improve the transportation efficiency of the ore.

[0044] Reference Figure 2 , Figure 3 and Figure 4As shown, since most of the ore is irregularly shaped after crushing, it is inevitable that the ore will get stuck when it is conveyed downward along the chute body 1, thus forming an ore pile that causes blockage. To avoid this problem, in this embodiment, the ore pile can be correspondingly broken. Specifically, there are two lifting plates 31, which are symmetrically distributed along the length direction of the chute body 1. The pile-breaking unit 3 further includes two through holes 34 opened in the horizontal section of the chute body 1. The positions of the through holes 34 correspond to those of the lifting plates 31. Two sliding grooves 35 are opened on both sides of the through hole 34 along the moving direction of the linkage plate 33. A displacement plate 36 that is slidably docked in the sliding groove 35 is hinged to the side of the linkage plate 33 away from the pin shaft 32. A driving component 37 for controlling the sliding of the linkage plate 33 to break the ore pile is installed between the pin shaft 32 and the chute body 1.

[0045] Further, in this embodiment, the driving component 37 includes a crankshaft 371 rotatably arranged on the inner wall of the through hole 34. The crankshafts 371 in the two through holes 34 are connected by a belt drive. A control motor 372 connected to any one of the crankshafts 371 is installed on the outer wall of the chute body 1 through a motor base. The crankshaft 371 is composed of a base shaft 373 and a crank web 374. Among them, the base shaft 373 is rotatably installed on the inner wall of the through hole 34, and the axis of the base shaft 373 is parallel to the axis of the pin shaft 32. Two groups of crank webs 374 are symmetrically arranged along the length direction on the base shaft 373. Each group of crank webs 374 has two, and a journal 375 is installed between the same group of crank webs 374; two lifting blocks 376 are symmetrically installed along the length direction at the lower end of the pin shaft 32. Two connecting blocks 377 corresponding to the positions of the lifting blocks 376 are rotatably sleeved on the crankshaft 371. A ball pin 378 is installed at the upper end of the connecting block 377. A spherical groove is opened at the lower end of the lifting block 376. The ball pin 378 is rotatably installed in the spherical groove. The connecting block 377 and the lifting block 376 are rotatably connected through the ball pin 378 and the spherical groove.

[0046] In the specific implementation process, the control motor 372 is started, and the control motor 372 drives the crankshaft 371 to rotate. The crankshaft 371 drives the journal 375 to perform circumferential movement through the crank web 374. The journal 375 drives the connecting block 377 to perform synchronous circumferential movement. The connecting block 377 drives the lifting block 376 and the pin shaft 32 to move up and down reciprocally through the cooperation between the ball pin 378 and the spherical groove. The pin shaft 32 drives the two linkage plates 33 connected thereto to cycle through the actions of bulging upward and resetting downward; when the linkage plate 33 bulges upward, it can support the ore in the chute body 1 to facilitate breaking up the ore pile, so that the ore pile disperses and quickly rolls down. When the linkage plate 33 resets downward, the linkage plate 33 is flush with the upper end of the horizontal section of the chute body 1. At this time, the ore in the chute body 1 can roll down more quickly, thereby improving the efficiency of transporting ore by the chute, effectively avoiding the influence of the ore pile caused by jamming and blockage on the transportation efficiency, and further avoiding the safety hazard caused by the ore pile accumulating too high and then the ore falling downward after exceeding the vertical section of the chute body 1.

[0047] During the process of the linkage plate 33 bulging upward and resetting downward, the linkage plate 33 drives the displacement plate 36 to slide adaptively in the sliding groove 35 to avoid interference, and the displacement plate 36 can close the through hole 34 to prevent the ore from falling through the through hole 34.

[0048] Refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown in

[0049] In order to avoid the ore getting stuck at the upper end of the linkage plate 33 and unable to roll down normally, in this embodiment, the ore at the upper end of the linkage plate 33 can be automatically dialed down. Specifically, in this embodiment, a plurality of through grooves parallel to the axis of the pin shaft 32 are formed on the linkage plate 33. A rotating shaft 331 is rotatably arranged in the through groove. A roller 332 is fixedly sleeved on the outer wall of the rotating shaft 331. A cylindrical groove is formed inside the pin shaft 32. A driving shaft 333 is rotatably installed in the cylindrical groove. The driving shaft 333 is connected to the plurality of rotating shafts 331 on the two linkage plates 33 through belt drives. An elastic belt 334 is sleeved together between the driving shaft 333 and the base shaft 373 in the middle of the crankshaft 371. The elastic belt 334 can undergo elastic deformation under the action of an external force and can rebound and reset when there is no external force.

[0050] In the specific implementation process, the control motor 372 drives the crankshaft 371 to rotate counterclockwise. The crankshaft 371 drives the drive shaft 333 to rotate synchronously counterclockwise through the base shaft 373. The drive shaft 333 drives the roller 332 to rotate counterclockwise through the rotating shaft 331. Thus, the roller 332 can dial down the ore at the upper end of the linkage plate 33 through the dialing plate 335, preventing the ore from jamming at the upper end of the linkage plate 33 and causing blockage, and the continuously rotating roller 332 can further improve the conveying efficiency of the ore.

[0051] Referring to Figure 2 As shown, during ore mining, since the chute needs to be in long-term operation for ore conveying, the chute body 1 is prone to severe wear. To avoid this problem, in this embodiment, the feeding unit 4 includes a plurality of through holes opened in the horizontal section of the chute body 1. These through holes are located between the two through holes 34. Two rotating rollers 11 are symmetrically and rotatably installed inside the through holes. The rotating rollers 11 are connected to the crankshaft 371 through a belt drive. During the rotation of the crankshaft 371, the rotating rollers 11 are driven to rotate synchronously. Thus, when the ore rolls down along the chute body 1, the rotating rollers 11 can make rolling contact with the ore, not only reducing the wear degree of the horizontal section of the chute body 1, but also being able to convey the ore downward through the rotating rollers 11, further improving the conveying efficiency.

[0052] Referring to Figure 7 and Figure 8 As shown, to further reduce the wear of the chute body 1, in this embodiment, the wear degree of the vertical section of the chute body 1 can also be reduced. Specifically, two groups of mounting holes are opened on both vertical sections of the chute body 1. Each group of mounting holes has two and is symmetrically distributed up and down. Two support shafts 41 are symmetrically and jointly penetrated along the length direction inside the two mounting holes in the same group. A conveyor belt 42 for conveying the ore downward is sleeved between the two support shafts 41 in the same mounting hole.

[0053] It should be noted that to ensure that the conveyor belt 42 dials the ore downward, in this embodiment, a plurality of dialing blocks 43 are evenly installed on the outer wall of the conveyor belt 42. The thickness of the dialing blocks 43 gradually decreases toward the side away from the conveyor belt 42. An accommodating area for dialing the ore is formed between two adjacent dialing blocks 43. A rotating column 44 is rotatably installed on the side of the dialing block 43 away from the conveyor belt 42.

[0054] Furthermore, in this embodiment, a driving bevel gear 45 is sleeved on the outer wall of any one of the crankshafts 371. A connecting shaft 46 is installed on the outer wall of the vertical section of the chute body 1 through a positioning plate. A linkage bevel gear 47 meshing with the driving bevel gear 45 is sleeved at the lower end of the connecting shaft 46. A transmission belt 461 is sleeved between the support shaft 41 close to the crankshaft 371 and the connecting shaft 46. Two fixed shafts 48 for supporting the transmission belt 461 are rotatably installed on the outer wall of the vertical section of the chute body 1 through a fixing plate.

[0055] In the specific implementation process, when the crankshaft 371 rotates, it drives the driving bevel gear 45 to rotate counterclockwise synchronously. The driving bevel gear 45 drives the connecting shaft 46 to rotate through the linkage bevel gear 47. The connecting shaft 46 drives the support shaft 41 to rotate counterclockwise through the transmission belt 461, and the support shaft 41 drives the conveyor belt 42 to rotate counterclockwise synchronously (shown in Figure 8 ), and the conveyor belt 42 drives the dial block 43 to move synchronously, so as to dial the ore in the vertical section of the chute body 1 downward; when the ore gets stuck in the vertical section of the chute body 1, the accommodation area between two adjacent dial blocks 43 can carry the ore and dial it downward, so as to break the jamming and blockage in the vertical section of the chute body 1, further improve the conveying efficiency of the ore, and the conveyor belt 42 can reduce the wear degree of the vertical section of the chute body 1.

[0056] In addition, when the ore rolls down along the chute body 1 and contacts the dial block 43, rolling friction can occur between the rotating column 44 and the ore, so as to reduce the frictional force of the ore, and further avoid interfering with the rolling of the ore.

[0057] It should be added that a plurality of guide bars 49 are equidistantly installed from top to bottom on the opposite sides of the two vertical sections of the chute body 1. A guiding track for guiding the ore to roll down smoothly is formed between two adjacent guide bars 49, which is used to separate the ore and avoid blockage caused by ore accumulation.

[0058] Embodiment Two:

[0059] Referring to Figure 9 and Figure 10 shown, on the basis of Embodiment One, since a large amount of dust will be generated when the crushed ore is conveyed downward, if no dust removal treatment is carried out, the dust is likely to affect the visibility of the working environment and pollute the environment. Based on this, a corresponding dust reduction unit 5 is also provided in this embodiment. Specifically, the dust reduction unit 5 includes a water storage bucket 51 installed at the upper end of the vertical section of the chute body 1. A plurality of placement holes are equidistantly formed along the length direction on the opposite sides of the two water storage buckets 51, and spray heads 52 are installed in the placement holes. Water tanks 53 are installed on the outer walls of the two support frames 2 on the upwardly inclined side of the chute body 1. A water pump 54 is installed at the upper end of the water tank 53. The water inlet end of the water pump 54 extends into the interior of the water tank 53, and the water outlet end of the water pump 54 extends into the interior of the water storage bucket 51.

[0060] Furthermore, since when the chute body 1 conveys ore, the dust on the ore falls downward along the through hole 34 and the through hole, in order to avoid the falling dust from flying and affecting the environment, in this embodiment, a receiving hopper 55 is installed at the lower end of the chute body 1 for receiving the falling dust, and a guiding cylinder 56 is installed at one end of the receiving hopper 55 close to the downwardly inclined chute body 1 for guiding the dust downward for collection.

[0061] In the specific implementation process, the water pump 54 is started. The water pump 54 pumps out the water in the water tank 53 and discharges it into the water storage bucket 51. Subsequently, the spray head 52 sprays water mist, thereby blocking the opening at the upper end of the chute body 1 in the form of water mist, so as to intercept the dust generated during the transportation of ore, prevent the dust from flying in the air and affecting the environment, and further ensure the visibility of the working site and the safety of the work.

[0062] During operation: Step 1: After the large-volume ore is crushed into block-shaped ore by the crusher, the ore is transported into the chute body 1 by the conveyor, so that the ore freely rolls down along the inclined chute body 1.

[0063] Step 2: The control motor 372 is started. The control motor 372 drives the crankshaft 371 to rotate. The crankshaft 371 drives the connecting block 377 to perform synchronous circumferential movement through the crank web 374 and the journal 375. The connecting block 377 drives the lifting block 376 and the pin shaft 32 to move up and down reciprocally as a whole. The pin shaft 32 drives the two linkage plates 33 connected thereto to cycle through the actions of bulging upward and resetting downward; when the linkage plate 33 bulges upward, it can prop up the ore in the chute body 1, so as to break up the ore pile, and after the ore pile is dispersed, it quickly rolls down; when the linkage plate 33 resets downward, the ore in the chute body 1 can roll down more quickly, thereby improving the efficiency of transporting ore by the chute and effectively avoiding the influence of the ore pile caused by jamming and blockage on the transportation efficiency.

[0064] Step 3: When the crankshaft 371 rotates counterclockwise, it drives the drive shaft 333 to rotate counterclockwise synchronously. The drive shaft 333 drives the roller 332 to rotate counterclockwise through the rotating shaft 331. Thus, the roller 332 can dial down the ore at the upper end of the linkage plate 33 through the dialing plate 335, preventing the ore from jamming at the upper end of the linkage plate 33 and causing blockage, and the continuously rotating roller 332 can further improve the transportation efficiency of the ore.

[0065] Step 4: When the crankshaft 371 rotates, it drives the driving bevel gear 45 to rotate counterclockwise synchronously. The driving bevel gear 45 drives the connecting shaft 46 to rotate through the linkage bevel gear 47. The connecting shaft 46 drives the support shaft 41 to rotate counterclockwise through the transmission belt 461. The support shaft 41 drives the conveyor belt 42 to rotate counterclockwise synchronously. The conveyor belt 42 drives the dialing block 43 to move synchronously, so as to dial down the ore in the vertical section of the chute body 1.

[0066] When the ore jams in the vertical section of the chute body 1, the accommodation area between two adjacent dialing blocks 43 can carry the ore and dial it down, thereby breaking the jamming and blockage in the vertical section of the chute body 1 and further improving the transportation efficiency of the ore.

[0067] Step 5: Start the water pump 54. The water pump 54 pumps out the water in the water tank 53 and discharges it into the water storage bucket 51. Subsequently, the spray head 52 sprays water mist, so as to block the opening at the upper end of the chute body 1 in the form of water mist, so as to intercept the dust generated during the transportation of ore, prevent the dust from flying in the air and affecting the environment, and further ensure the visibility of the working site and the safety of the work.

[0068] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.

[0069] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
