Description

Technical Field

[0001] This invention relates to the field of mining technology, specifically to an ore collection device and method for mines. Background Technology

[0002] Centralized hoisting plays a crucial role in mine production, reducing labor costs, simplifying operations, increasing labor productivity, lowering energy consumption, and enhancing inherent safety. In ore mining, situations arise where ore supply points are dispersed and far from existing collection systems. In such cases, it's necessary to first study the drawings and current state of each section's engineering to determine the optimal location, utilizing existing infrastructure as much as possible to minimize engineering work and reduce production costs, thereby achieving centralized hoisting.

[0003] Currently, when using centralized ore supply and hoisting methods to transfer ore, after the ore is poured into the mine, it falls irregularly and over a wide area in the mine exit roadway. This requires loader or even manual labor to collect and assist in loading the ore, which wastes manpower, greatly reduces work efficiency, increases transfer costs, and is inconvenient to use. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a ore collection device and method for mines. It can limit and block falling ore, prevent ore from splashing in the tunnel, help ore to accumulate, and can also transfer, transport and load the accumulated ore. There is no need for loader and manual ore collection operations, saving manpower, greatly improving work efficiency and reducing transportation costs. It is easy to use and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mine ore collection device, comprising a enclosure installed on the lower side of the mine, the enclosure comprising two symmetrically installed enclosure plates, the two ends of which are connected by a connecting plate, a right-angle side baffle symmetrically arranged between the two enclosure plates and perpendicular to the enclosure plates, the right-angle side baffle being movable along the length of the enclosure plates, and a vertical cylinder for driving the right-angle side baffle to tilt at its bottom, a groove is provided on the ground below the two right-angle side baffles, and a horizontal conveyor belt for conveying ore is installed inside the groove, and an inclined installation groove is provided on the ground corresponding to the end of the horizontal conveyor belt, and an inclined feeding conveyor belt is installed inside the inclined installation groove.

[0006] As a preferred embodiment of the present invention, a horizontal cylinder is installed on the connecting plate, and a base plate is provided at the telescopic end of the horizontal cylinder. The bottom of the right-angle side baffle away from the connecting plate is rotatably connected to the base plate.

[0007] As a preferred embodiment of the present invention, the bottom of the vertical cylinder is mounted on a base plate.

[0008] As a preferred embodiment of the present invention, the upper surface of the base plate is provided with uniformly distributed shock-absorbing pads.

[0009] As a preferred embodiment of the present invention, a rectangular groove is provided on the ground corresponding to the base plate, and a guide roller assembly is installed inside the rectangular groove.

[0010] A method for concentrating ore using a mine concentrator includes the following steps: S1. A groove, an inclined installation groove, and a rectangular groove are opened on the roadway below the discharge port of the ore collection shaft. Then the device is installed, and the two right-angle side baffles are kept close together. At this time, the right-angle side baffles block the horizontal conveyor belt, and the enclosure and the right-angle side baffles form a enclosure to collect the ore falling in the ore collection shaft. S2. Pour the ore into the collection shaft. The ore falls into the enclosure along the collection shaft. The enclosure and right-angle side baffles limit and block the ore. S3. During non-ore dropping periods, control the horizontal cylinder to work. The horizontal cylinder pulls the bottom plate to move, and the bottom plate drives the right-angle side baffle to move, so that a gap appears between the two right-angle side baffles. At this time, the ore inside the enclosure falls into the horizontal conveyor belt through the gap. S31. Control the vertical cylinder to work. The vertical cylinder pushes the right-angle side baffle to rotate a certain angle, so that the right-angle side baffle tilts, thereby causing the ore at the edge of the right-angle side baffle to slide onto the horizontal conveyor belt. S4. The horizontal conveyor belt transports the ore to the feeding conveyor belt. The ore car is placed under the discharge end of the feeding conveyor belt. The feeding conveyor belt transports the ore to the ore car. Then, the ore is transferred and transported in the tunnel by the ore car.

[0011] Compared with the prior art, the beneficial effects of the present invention are: The ore collection device for mine shafts exemplified by this invention can limit and block falling ore, preventing ore from splashing in the tunnel and facilitating ore accumulation. It can also transfer, transport, and load the accumulated ore without the need for loader and manual labor, saving manpower, greatly improving work efficiency, reducing transportation costs, and is easy to use.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figure 1-3 This invention provides a technical solution: a mine ore collection device, comprising a barrier installed on the lower side of the mine shaft. The barrier includes two symmetrically installed enclosure plates 1, with their ends connected by a connecting plate 2. A right-angled side baffle 4, perpendicular to the enclosure plates 1, is symmetrically arranged between the two enclosure plates 1. The enclosure plates 1 and the right-angled side baffle 4 form a barrier for collecting ore falling into the mine shaft. The right-angled side baffle 4 is movable along the length of the enclosure plates 1, and its bottom is equipped with a vertical cylinder 6 for tilting it. A groove is provided on the ground below the two right-angled side baffles 4, and a horizontal conveyor belt 7 for conveying ore is installed inside the groove. An inclined installation groove is provided on the ground corresponding to the end of the horizontal conveyor belt 7, and an inclined feeding conveyor belt 8 is installed inside the inclined installation groove. The horizontal conveyor belt 7 conveys the ore to the feeding conveyor belt 8. The ore car is placed below the discharge end of the feeding conveyor belt 8, and the feeding conveyor belt 8 conveys the ore to the ore car. Then, the ore can be transferred and transported in the tunnel by the ore car.

[0016] Furthermore, a horizontal cylinder 21 is installed on the connecting plate 2. The telescopic end of the horizontal cylinder 21 is provided with a base plate 3. The bottom of the right-angle side baffle 4 on the side away from the connecting plate 2 is rotatably connected to the base plate 3. During non-ore dropping periods, the horizontal cylinder 21 is controlled to work, and the horizontal cylinder 21 pulls the base plate 3 to move. The base plate 3 drives the right-angle side baffle 4 to move, thereby creating a gap between the two right-angle side baffles 4. At this time, the ore inside the enclosure falls into the horizontal conveyor belt 7 through the gap.

[0017] Furthermore, the bottom of the vertical cylinder 6 is mounted on the base plate 3.

[0018] Furthermore, the upper surface of the base plate 3 is provided with evenly distributed shock-absorbing pads 5. When the ore falls on the right-angle side baffle 4, the shock-absorbing pads 5 can buffer and protect the right-angle side baffle 4.

[0019] Furthermore, a rectangular groove is provided on the ground corresponding to the base plate 3, and a guide roller group 9 is installed inside the rectangular groove to reduce friction when the base plate 3 moves.

[0020] A method for concentrating ore using a mine concentrator includes the following steps: S1. A groove, an inclined installation groove, and a rectangular groove are opened on the roadway below the discharge port of the ore collection shaft. Then the device is installed and the two right-angle side baffles 4 are kept close together. At this time, the right-angle side baffles 4 block the horizontal conveyor belt 7. At the same time, the enclosure 1 and the right-angle side baffles 4 form a enclosure to collect the ore falling in the ore collection shaft. S2. Pour the ore into the collection well. The ore falls into the enclosure along the collection well. The enclosure 1 and the right-angle side baffle 4 limit and block the ore. S3. During non-ore falling period, control the horizontal cylinder 21 to work. The horizontal cylinder 21 pulls the bottom plate 3 to move. The bottom plate 3 drives the right-angle side baffle 4 to move, so that a gap appears between the two right-angle side baffles 4. At this time, the ore inside the enclosure falls into the horizontal conveyor belt 7 through the gap. S31. Control the vertical cylinder 6 to work. The vertical cylinder 6 pushes the right-angle side baffle 4 to rotate at a certain angle, so that the right-angle side baffle 4 tilts, thereby causing the ore at the edge of the right-angle side baffle 4 to slide onto the horizontal conveyor belt 7. S4. The horizontal conveyor belt 7 transports the ore to the feeding conveyor belt 8. The ore car is placed under the discharge end of the feeding conveyor belt 8. The feeding conveyor belt 8 transports the ore to the ore car. Then, the ore is transferred and transported in the tunnel by the ore car.

[0021] This invention can limit and block falling ore, preventing it from splashing in the tunnel and helping to collect the ore. It can also transfer, transport and load the collected ore without the need for loader and manual labor, saving manpower, greatly improving work efficiency and reducing transportation costs. It is also easy to use.
