Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to an ore crushing device. Background Technology

[0002] In the field of mining engineering, ore crushers are often used to crush the stones produced during mining to meet the needs of subsequent processing, transportation or mineral processing.

[0003] In practice, the stone extracted from mines contains a lot of solid waste. Existing common ore crushers crush the ore and solid waste together, resulting in a mixture of crushed ore and solid waste that is difficult to separate. This requires further processing in a screening process. However, during the transportation of the stone, the crushed solid waste takes up a lot of transport space, reducing transportation efficiency and increasing transportation costs. Therefore, this application proposes an ore crushing device capable of preliminary screening of crushed stone. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0024] See Figures 1-3 .

[0025] This utility model discloses an ore crushing device, comprising:

[0026] The crushing component 1 includes a crushing cylinder 11 and a crushing cone 12 vertically arranged inside the crushing cylinder 11. The crushing cone 12 is used to crush stone. An eccentric sleeve 13 is provided below the crushing cone 12 to drive the crushing cone 12 to make a gyratory motion inside the crushing cylinder 11.

[0027] The first positioning sleeve 2 is disposed at the bottom end of the crushing component 1 and is used to support the crushing component 1;

[0028] The driving component 3 is disposed inside the first positioning sleeve 2 and connected to the eccentric sleeve 13. The driving component 3 is used to drive the eccentric sleeve 13 to rotate.

[0029] The screening component 4 includes a rotating sleeve 41 disposed within the first positioning sleeve 2. The top end of the rotating sleeve 41 is connected to a driving component 3, which drives the rotating sleeve 41 to rotate around its axis. Multiple feed inlets 411 are vertically distributed on the rotating sleeve 41. A second positioning sleeve 42 is disposed below the rotating sleeve 41, and the rotating sleeve 41 is rotatably mounted on the second positioning sleeve 42. The bottom end of the second positioning sleeve 42 is connected to the first positioning sleeve 2, and the second positioning sleeve 42 supports the rotating sleeve 41. Multiple filter screens 43 are vertically distributed on the rotating sleeve 41, with the mesh size of each filter screen 43 increasing sequentially from top to bottom. Each filter screen 43 is conical, wider at the top and narrower at the bottom, with the smaller diameter end sliding and rotating on the corresponding end of the rotating sleeve 41. Below the feed inlet 411, the larger diameter end slides vertically on the inner wall of the first positioning sleeve 2. Each filter screen 43 is also provided with a shaking component 44. When the rotating sleeve 41 rotates, each shaking component 44 drives the corresponding filter screen 43 to move up and down on the rotating sleeve 41. Multiple collection hoppers 45 are also vertically distributed in the rotating sleeve 41. Each collection hopper 45 is located below the corresponding feed inlet 411. Each collection hopper 45 has a conveying pipe 46 at its outlet. The outlet of the conveying pipe 46 passes through the side wall of the second positioning sleeve 42 and extends out of the first positioning sleeve 2. The conveying pipe 46 is used to convey the screened stone. Each conveying pipe 46 also has a screening component 47 at its outlet. The screening component 47 is used to screen the solid waste and ore in the stone conveyed by the conveying pipe 46.

[0030] In practice, the unloading truck feeds the mined stone into the crushing component 1. The driving component 3 drives the crushing cone 12 to rotate within the crushing cylinder 11 via the eccentric sleeve 13, thereby crushing the stone. The driving component 3 also drives the rotating sleeve 41 to rotate around its axis. The crushed stone falls into the first positioning sleeve 2 under gravity. During the fall, the smaller-diameter stones pass through a filter screen 43 with a mesh size larger than their own size until they fall into a filter screen 43 of the corresponding mesh size. The upper part of the sleeve 41 rotates, and each shaking component 44 drives the corresponding filter screen 43 to move up and down repeatedly, thereby shaking the stone on the corresponding filter screen 43, improving the screening efficiency of the filter screen 43, and assisting the stone to fall into the corresponding collection hopper 45 through the feed port 411. Under the action of gravity, the stone enters the conveying pipe 46 and is transported to the screening component 47. The screening component 47 performs preliminary screening of the solid waste in the stone and the ore, thereby removing the solid waste.

[0031] This invention, through the cooperation of the driving component 3 and the screening component 4, first classifies the stones according to their size by the cooperation of each filter screen 43 and the corresponding shaking component 44. The classified stones are then transported to the screening component 47, which screens the solid waste and ore in the stones, thereby removing the solid waste and screening stones of similar size together, further improving the screening accuracy. In the subsequent transfer process, only the screened ore needs to be transferred, saving transfer space, thereby increasing transportation efficiency and reducing transfer costs.

[0032] It should be noted that the specific structure and function of the crushing component 1 can be referred to the gyratory crusher in the prior art, and the gyratory crusher is common knowledge in the art, so it will not be described in detail here.

[0033] In one embodiment, the driving component 3 includes a transmission rod 31 vertically rotatably inserted into a rotating sleeve 41. The transmission rod 31 passes through each collection hopper 45 and has a rotating disk 32 at its top. The top surface of the rotating disk 32 is connected to the eccentric sleeve 13, and the bottom end is connected to the rotating sleeve 41. When the transmission rod 31 rotates, it drives the eccentric sleeve 13 and the rotating sleeve 41 to rotate together through the rotating disk 32. The bottom end of the transmission rod 31 is also provided with a power unit 33, which is used to drive the transmission rod 31 to rotate. A protective sleeve 34 is also rotatably sleeved on the transmission rod 31. The bottom end of the protective sleeve 34 is connected to the first positioning sleeve 2, and the protective sleeve 34 is used to protect the transmission rod 31.

[0034] With this design, when it is necessary to crush stone, the power unit 33 drives the transmission rod 31 to rotate and drives the eccentric sleeve 13 and the rotating sleeve 41 to rotate through the rotating disk 32, so that the crushing cone 12 crushes the stone in the crushing cylinder 11. When the rotating sleeve 41 rotates, it drives each shaking component 44 to move the corresponding filter screen 43 up and down reciprocally. When the stone enters each collection hopper 45, the protective sleeve 34 is used to protect the transmission rod 31 from interference by the stone.

[0035] It should be noted that the power unit 33 can be an electric motor from the prior art.

[0036] In one embodiment, the shaking component 44 includes a first connecting ring 441 sleeved on a rotating sleeve 41. The first connecting ring 441 is disposed below the corresponding filter screen 43 and has a plurality of first protrusions 442 distributed on its top surface. The bottom surface of the corresponding filter screen 43 has a plurality of second protrusions 443 that correspond one-to-one with each of the first protrusions 442. A second connecting ring 444 is also rotatably sleeved on the first connecting ring 441. A plurality of support rods 4441 are distributed on the second connecting ring 444. Each support rod 4441 is connected to the inner wall of the first positioning sleeve 2. An elastic unit 445 is also provided between the second connecting ring 444 and the corresponding filter screen 43. The elastic unit 445 applies a vertically downward pulling force to the corresponding filter screen 43.

[0037] With this design, when the rotating sleeve 41 rotates, it drives each first connecting ring 441 to rotate around the center of the rotating sleeve 41. Each first protrusion 442 on the first connecting ring 441 rotates with the first connecting ring 441 and contacts the corresponding second protrusion 443. As the first connecting ring 441 continues to rotate, each first protrusion 442 presses against the corresponding second protrusion 443 and applies an upward thrust to the filter screen 43. At this time, the filter screen 43 moves upward and the elastic unit 445 is stretched. When each first protrusion 442 separates from the corresponding second protrusion 443, the elastic unit 445 loses its constraint and drives the filter screen 43 to move downward until each first protrusion 442 presses against the corresponding second protrusion 443 again, thereby driving the filter screen 43 to move up and down reciprocally. When the first connecting ring 441 rotates, each support rod 4441 prevents the corresponding second connecting ring 444 from rotating with the first connecting ring 441, ensuring that the elastic unit 445 works normally.

[0038] Preferably, the elastic element 445 can be a tension spring as in the prior art.

[0039] In one embodiment, the screening component 47 includes a first conveyor belt assembly 471 disposed at the outlet of the corresponding conveying pipe 46. A first collection box 472 is disposed below the end of the first conveyor belt assembly 471 away from the corresponding conveying pipe 46. The first collection box 472 is used to collect solid waste in the stone. A second collection box 473 is disposed below the end of the first conveyor belt assembly 471 near the corresponding conveying pipe 46. The second collection box 473 is used to collect ore in the stone. A magnetic attraction component 474 is disposed in the first conveyor belt assembly 471. The magnetic attraction component 474 is used to attract iron in the stone located on the first conveyor belt assembly 471. A magnetic isolation component 475 is disposed in the first conveyor belt assembly 471 located above the second collection box 473. The magnetic isolation component 475 is used to prevent the magnetic force of the magnetic attraction component 474 from being transmitted to the first conveyor belt assembly 471 above the second collection box 473.

[0040] With this design, after the stone is screened by each filter screen 43, it is transported to the corresponding first conveyor belt assembly 471 through each conveyor pipe 46. The first conveyor belt assembly 471 drives the stone to move. At this time, the magnetic attraction component 474 attracts the ore in the stone, causing the ore to be adsorbed onto the conveyor belt of the first conveyor belt assembly 471. When the stone moves to the end of the first conveyor belt assembly 471 away from the corresponding conveyor pipe 46, as the first conveyor belt assembly 471 continues to transport the stone, the solid waste in the stone can no longer be attracted by the magnetic attraction component 474 and falls into the first collection box 472. The ore in the stone is still adsorbed and moves with the conveyor belt until the ore moves to the bottom of the magnetic isolation component 475. At this time, the magnetic isolation component 475 isolates the magnetic force of the magnetic attraction component 474, and the ore is no longer attracted and falls into the second collection box, thereby realizing the screening of solid waste and ore in the stone.

[0041] In one embodiment, a discharge port 21 is provided below the first positioning sleeve 2;

[0042] The first positioning sleeve 2 is also provided with a discharge component 5 on one side. The discharge component 5 includes a guide plate 51 that is inclinedly arranged inside the first positioning sleeve 2. The guide plate 51 is arranged below each conveying pipe 46, and the second positioning sleeve 42 is vertically inserted through the guide plate 51. The guide plate 51 is connected to the inlet of the discharge port 21. The guide plate 51 is used to discharge impurities and waste materials inside the first positioning sleeve 2. A second conveyor belt assembly 52 is provided on the side near the outlet of the discharge port 21. The second conveyor belt assembly 52 is used to convey the impurities and waste materials discharged by the guide plate 51.

[0043] With this design, after the stone is crushed and processed, some of the stone, due to its small size, passes through all the filters 43 in sequence and falls onto the guide plate 51. This part of the stone is difficult to process. The stone on the guide plate 51 moves along the inclined direction of the guide plate 51 and is conveyed to the second conveyor belt assembly 52 through the discharge port 21. The second conveyor belt assembly 52 transfers the stone discharged from the guide plate 51 to a suitable collection point, thereby avoiding the accumulation of stone in the first positioning sleeve 2 and affecting the operation of the first positioning sleeve 2.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, "multiple," "multiple groups," and "several" refer to two or more.
