Description

Technical Field

[0001] The invention belongs to the technical field of ore mining and transportation, and in particular relates to an ore transportation device. Background Art

[0002] Ore conveyor is a kind of equipment used to transport ore from mines or ore processing plants to other places. It is usually composed of conveyor belts, rollers, support frames and transmission devices, which can improve the efficiency of ore transportation and reduce labor costs. Ore is usually transported in a crushed state. Some ore powder in the crushed ore will fly into the air during transportation, which is not good for the health of workers and will cause the loss of ore during transportation.

[0003] In order to reduce the interference of external airflow on the dust removal mist, the spray dust removal components on existing ore conveying machinery usually set the distance between the nozzle and the conveyor belt to be shorter, so that the mist is closer to the ore and can be directly sprayed to reduce dust. However, this makes the nozzle very easy to collide with large volumes of ore and be damaged. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating 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 understood as limiting the present invention.

[0027] See also Figure 1 As shown, the present invention is an ore conveying device, including a conveyor 1 for conveying ore. A water spraying mechanism is installed on the frame of the conveyor 1. The water spraying mechanism is used to spray water to wet the ore conveyed on the conveyor 1 to prevent dust attached to the surface of the ore from being raised and polluting the environment during the conveying process.

[0028] In order to facilitate the installation of the water spray mechanism and protect the water spray nozzle 25 of the water spray mechanism when in use, the water spray mechanism provided by the present invention includes a spray pipe 2 and a bracket for supporting and fixing the spray pipe 2, and the bracket is fixed on the frames on both sides of the conveyor 1; Figure 2 The bracket includes an "I"-shaped column 5 welded / bolted to the frame, a bearing seat 50 is installed on the top surface of the column 5 through a fixing bolt 51, and a bearing is installed on the bearing seat 50; and the two ends of the spray pipe 2 are respectively connected to fixing rods 21, and the fixing rods 21 are installed on the bearings. At the same time, a plurality of water spray nozzles 25 are arranged on the peripheral side of the spray pipe 2 along its length direction, and a protective mechanism 4 for protecting the water spray nozzle 25 is installed on the outer peripheral side wall of the spray pipe 2. The protective mechanism 4 is a set of ring structures arranged on the outside of the spray pipe 2 ; Based on the above-mentioned arrangement, when there is a part of the ore that is highly protruding, when this part of the ore moves past the position of the spray pipe 2, the ore will abut against the protective mechanism 4 and drive the spray pipe 2 to rotate around the bearing under the action of the protective mechanism 4. At this time, the distance between the bottom end of the protective mechanism 4 and the conveying surface of the conveyor 1 gradually increases with the rotation of the protective mechanism 4, and then the ore passes through the gap between the spray pipe 2 and the conveying surface of the conveyor 1. After the ore passes through, under the action of its own gravity, the spray pipe 2 rotates around the bearing to restore its initial position.

[0029] When in use, in order to conveniently limit the spray pipe 2 from rotating around the bearing, as Figure 2 A fixing ring 26 is fixed to the outer wall of the end of the fixing rod 21, a limiting rod A27 is arranged on the outer side of the fixing ring 26, and a limiting rod B51 cooperating with the limiting rod A27 is arranged on the top side of the bracket to control the rotation of the spray pipe 2 around the bearing. When rotating 180° or 90°, the limiting rod A abuts against one side of the limiting rod B51, thereby preventing the spray pipe 2 from continuing to rotate.

[0030] Specifically, a through channel is provided at one end of the fixing rod 21 along its axial direction, and a water inlet pipe joint 21 connected to the spray pipe 2 is installed in the channel. When in use, the water inlet pipe joint 21 is connected to the water supply pipeline.

[0031] When using it specifically, Figure 2 In the present invention, a plurality of inner sleeves 22 are arranged on the circumferential side of the spray pipe 2 along its length direction, an opening is arranged on the spray pipe 2 inside the inner sleeve 22, a sleeve 23 with a water spray nozzle 25 installed at the end thereof is arranged on the outer side of the inner sleeve 22, and a locking bolt 24 is arranged on the sleeve 23; the water spray nozzle 25 is connected to the opening through a hose, that is, the distance between the water spray nozzle 25 and the conveying surface of the conveyor 1 can be adjusted according to actual needs during use.

[0032] When in use, in order to facilitate the installation of the protection mechanism 4, a mounting structure is first installed on the outer wall of the spray pipe 2, and then the protection mechanism 4 is installed on the mounting structure; Figure 3-5, wherein the mounting structure includes two clamping rings 30 that are matched and encircled and fixed on the outer wall of the spray pipe 2, and the two ends of the clamping ring 30 are respectively provided with a fastening part A31 and a fastening part B32, and a connecting rod A34 is provided on the outer side of the clamping ring 30, and the end of the connecting rod A34 is connected to the connecting rod B35, and the end of the connecting rod B35 is provided with a connecting seat 36, and the connecting seat 36 is connected to the inner wall of the protective mechanism 4; and a positioning block 28 is provided on one side of the inner sleeve 22, and the positioning block 28 is located between the two fastening parts B32, and the two fastening parts A31 are connected together by a fixing assembly including bolts and nuts; the fastening part B32 is fixed to the positioning block 28 by a fastening bolt 33.

[0033] Specifically, in one possible implementation, when the diameter of the spray pipe 2 is 4.2 cm, the protective mechanism 4 includes a minor arc segment 40 with an arc radius of 15 cm, and a major arc segment 41 with an arc radius of 11 cm; and during installation, the connecting seat 36 is welded to the inner wall of the major arc segment 41, and after installation, the water spray nozzle 25 is located between the two connecting rods A34.

[0034] After installation, the middle parts of the inferior arc segment 40 and the superior arc segment 41 are respectively located directly above and directly below the water spray nozzle 25; and the distance between the superior arc segment 41 and the spray pipe 2 gradually decreases from the middle part of the superior arc segment 41 to both ends; its implementation is convenient when the protective mechanism 4 contacts an obstacle. At this time, under the cooperation of the conveyor 1 and the obstacle, the water spray mechanism is driven to rotate to increase the distance between the water spray mechanism and the conveying surface of the conveyor 1, so as to facilitate the obstacle to pass from under the water spray mechanism.

[0035] Specifically, threaded holes threadedly connected to the fastening bolts 33 are provided on both sides of the positioning block 28, and a through hole for the fastening bolts 33 to pass through is provided on the fastening portion B32.
