Description

Technical Field

[0001] The present invention belongs to the technical field of ore mining and conveying, and particularly relates to an ore crushing and conveying device. Background Art

[0002] An ore conveyor is a device used to convey ore from a mine or an ore processing plant to other places. It usually consists of components such as a conveyor belt, rollers, a support frame, and a transmission device, which can improve the conveying efficiency of ore and reduce labor costs. Ore is usually transported in a crushed state, and some of the crushed ore powder will fly into the air during the conveying process, which is not conducive to the health of workers and will cause losses of ore during the conveying process. The spray dust removal assembly on the existing ore conveying machinery is to reduce the blowing interference of external airflows on the dust removal mist; however, after long-term use, along with the action of the water mist, powdery ore will adhere to the conveyor belt of the conveying machinery. When it is not cleaned for a long time, the self-weight of the belt will change, affecting the use of the conveying machinery. Summary of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0027] Please refer to Figure 1 As shown, the present invention is an ore crushing and conveying device, which includes a belt conveyor line body 1 for conveying ore. A water spraying and dust reduction component 3 and a belt cleaning component 4 are respectively installed at the feeding end and the discharging end of the belt conveyor line body 1. By using the settings of the water spraying and dust reduction component 3 and the belt cleaning component 4, when in use, the water spraying and dust reduction component 3 sprays water mist on the ore conveyed on the belt for dust reduction, and at the same time, the belt cleaning component 4 is used to remove the impurities attached to the belt.

[0028] In order to facilitate the spraying of water mist, and as much as possible set the distance between the nozzle and the conveyor belt shorter during use, so that the mist is closer to the ore and can directly spray for dust reduction, and during use, to avoid when some ore is conveyed to the nozzle, due to itself or being piled up together, some ore directly contacts the nozzle and causes damage to the nozzle. For example Figures 2-3 The water spraying and dust reduction component 3 provided by the present invention includes a gantry 30 with mounting feet 31 provided at both ends. A spray pipe 38 is installed on the gantry 30, and a round rod 32 is installed on the gantry 30 below the spray pipe 38. A number of rotating rings 33 are rotatably installed on the round rod 32. One side of the rotating ring 33 is connected to a vertical rod 35. A mounting seat 351 is provided on one side of the vertical rod 35. A nozzle 36 is installed on the mounting seat 351. The spray pipe 38 is connected to the nozzle 36 through a hose 37, and the gantry 30 is installed above the frame of the belt conveyor line body 1. Based on the above settings, by using the setting of the vertical rod 35, when the ore hits the vertical rod 35, at this time, it drives the end of the vertical rod 35 to rotate around the round rod 32, and thus at this time, the ore is prevented from contacting the nozzle 36.

[0029] In order to facilitate the restriction of the left - right deflection of the rotating ring 33, limit rings 34 are installed on the round rod 32 on both sides of any rotating ring 33, and at least one locking bolt 341 is provided on the limit ring 34.

[0030] At the same time, the present invention provides a convex platform 331 on the outer side wall of the rotating ring 33, and one end of the vertical rod 35 is welded to the convex platform 331, which is convenient for replacing the new vertical rod 35 by a simple welding method when the vertical rod 35 is damaged during long - term use.

[0031] It can be known that the belt cleaning assembly 4 provided by the present invention includes a dust removal cover covering the belt under the frame of the belt conveyor line body 1, and a cleaning mechanism arranged in the dust removal cover. The dust removal cover includes a rectangular tubular housing 40 installed under the frame through a fixed column and for the belt to pass through. The cleaning mechanism is arranged on the inner bottom surface of the housing 40 and is used to clean the outer surface of the belt passing through the housing 40. A discharge port is arranged on the bottom surface of the housing 40, and a discharge hopper 2 with an opening gradually decreasing from top to bottom is connected to the outer bottom surface of the housing 40 at the discharge port. Thus, during use, the dust attached to the outer surface of the belt is cleaned by the cleaning mechanism, and the cleaned dust falls into the discharge hopper 2. A receiving box can be arranged at the bottom end of the discharge hopper 2 for collection and centralized treatment, or a discharge chute can be arranged at the discharge port of the discharge hopper 2, and the discharge end of the discharge chute is controlled to be located above the belt conveyor line body 1 for treatment.

[0032] It should be noted that the cleaning mechanism provided by the present invention includes a cleaning roller, as Figure 5 , mounting blocks 46 are respectively connected to both ends of the cleaning roller. Guide elastic telescopic modules 47 are connected to the upper and lower side surfaces of the mounting blocks 46, and the ends of the guide elastic telescopic modules 47 are mounted on the inner bottom surface / inner top surface of the housing 40. The cleaning roller includes a rod body A461 at the center. A rod sleeve A462 is connected to the peripheral side of the rod body A461 through a bearing A. Cleaning bristles 463 are fixed on the outer peripheral side wall of the rod sleeve A462. Thus, during use, the up and down movement of the belt drives the up and down movement of the cleaning roller, and at the same time, the rod sleeve A462 of the cleaning roller is driven to rotate around the rod body A461 under the drive of the belt transmission. Then, the cleaning bristles 463 are used to clean the dust attached to the outer surface of the belt.

[0033] During the cleaning process, in order to avoid a large amount of dust flying generated during the falling process of the dust cleaned from the outer surface of the belt from escaping into the air, as Figure 4 , the present invention sets protruding portions 401 at the top ends of both ends of the housing 40. Elastic telescopic mechanisms 43 are respectively connected to both ends of the bottom surface of the protruding portions 401 with a fixed block 41. A notch 411 stuck on the end face of the housing 40 is arranged on one side of the fixed block 41. A supporting roller 42 pressing against the outer surface of the belt and a dust blocking plate 45 blocking the end of the housing 40 are connected between the two fixed blocks 41. During use, the up and down movement of the belt drives the up and down movement of the supporting roller 42, and then drives the up and down movement of the dust blocking plate 45.

[0034] In order to control the dust blocking plate 45 to always cover the entire end face of the housing 40 located below the supporting roller 42 during the up and down movement of the dust blocking plate 45 during use, as Figure 7, the provided dust shield 45 includes a rectangular plate A 50 and a rectangular plate B 451 that cooperate with each other. The rectangular plate A 450 is connected to the bottom side of the fixed block 41; a rectangular groove 452 for inserting the rectangular plate A 450 is provided on the rectangular plate B 451, and a through hole 453 is provided on the bottom side of the rectangular groove 452. A limiting rod 455 passing through the through hole 453 is provided on one side of the rectangular plate A 450, and a limiting end plate 454 is provided at the end of the limiting rod 455.

[0035] It should be noted that in order to keep the fixed block 41 vertically movable during use, a convex block 412 is provided on one side of the fixed block 41, and an installation convex plate 402 is fixed on the outer side wall of the housing 40 on both sides of the convex block 412. A guide rod 44 that movably penetrates the convex block 412 is connected between the two installation convex plates 402.

[0036] At the same time, the present invention is provided with a side plate 11 on the frame that cooperates with the dust shield 45, and the dust shield 45 is located in the gap formed by the side plate 11 and the end of the housing 40; as Figure 6 , and the idler roller 42 includes a rod body B 420 at the center. A rod sleeve B 422 is connected to the peripheral side of the rod body B 420 through a bearing B 421, and a rubber layer 423 or a felt layer is fixed on the outer peripheral side wall of the rod sleeve B 422.
