Description

Technical Field

[0001] The invention relates to the technical field of conveyor stacking and unloading equipment, and in particular to a large-span unloading device for a belt conveyor. Background Art

[0002] The large-span unloading and stacking devices of belt conveyors are suitable for a variety of occasions. In mines and quarries, belt conveyors are used to transport mined minerals from the mining face to processing plants or storage areas. In the power and coal industries, belt conveyors are used to transport coal from the mining site to power plants, or to carry out material handling within power plants. In bulk material yards, such as coal and ore yards, belt conveyors combined with large-span unloading devices can perform efficient stacking and reclaiming operations.

[0003] In the related art, large-span unloading and stacking devices are generally only capable of unloading and stacking at fixed points, that is, they can only unload and stack at fixed positions, and cannot meet the requirements of multi-point unloading and stacking conditions. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that a large-span unloading device cannot meet the requirements of multi-point unloading and stacking working conditions, and to propose a large-span unloading device for a belt conveyor.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A large-span unloading device for a belt conveyor comprises a main belt conveyor, wherein the main belt conveyor comprises a main conveyor belt, and the main conveyor belt has a main upper belt. The unloading device comprises a transfer conveying device and a translation device. The main upper belt has a transfer belt portion, and the transfer belt portion can change its position along the length direction of the main upper belt. The transfer conveying device is installed on the translation device, and the transfer belt portion can transport materials upstream thereof to the transfer conveying device.

[0007] It is defined that the main upper belt located upstream of the transfer belt portion is the front belt portion, and the downstream is the rear belt portion. The transfer belt portion includes an inclined belt portion and a folded belt portion. One end of the inclined belt portion is connected to the front belt portion, and the other end is connected to the folded belt portion. The other end of the folded belt portion is connected to the rear belt portion. A concave space is formed between the folded belt portion and the rear belt portion, and the material receiving portion of the transfer conveying device is at least partially located in the concave space.

[0008] A rotatable first roller is installed between the inclined belt portion and the folded belt portion, and a rotatable second roller is installed between the folded belt portion and the rear belt portion. The first roller and the second roller are installed on the translation device.

[0009] The translation device includes a support track arranged along the length direction of the main upper belt and a walking platform capable of walking on the support track, and the first roller and the second roller are rotatably installed on the walking platform.

[0010] The transfer conveying device includes an inclined transfer conveyor and a diverter conveyor located downstream and below the transfer conveyor. The transfer conveyor and the diverter conveyor are both installed on a translation device. The material conveying direction of the diverter conveyor has an angle greater than zero with the movement direction of the main upper belt.

[0011] A material distribution mechanism is provided between the downstream and lower part of the transfer conveyor and the diversion conveyor. The material distribution mechanism is installed on a translation device. The diversion conveyor includes at least two first conveyors that convey materials in different directions. The material distribution mechanism can divert the material transported by the transfer conveyor to multiple first conveyors separately or simultaneously.

[0012] The invention proposes a large-span unloading device for a belt conveyor, which has the following beneficial effects: when the device is working, the material is transported above the main upper belt of the main belt conveyor, and the main upper belt is provided with a transfer belt portion that can change its position. When the transfer belt portion is located at different positions, the material on the main upper belt at that time can be cut off. When the material moves to the transfer belt portion, it is transferred to the transfer conveying device through the transfer belt portion, and the transfer conveying device is used for midway unloading and stacking. The transfer conveying device is moved by the translation device so that the position of the transfer conveying device is adapted to the position of the transfer belt portion, thereby achieving the purpose of multi-point unloading and stacking.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 7 A belt conveyor large-span unloading device includes a main belt conveyor, the main belt conveyor includes a main conveyor belt 1, the main conveyor belt 1 has a main upper belt 2, the unloading device includes a transfer conveying device and a translation device, the main upper belt 2 has a transfer belt portion 6, the transfer belt portion 6 can change its position along the length direction of the main upper belt 2, the transfer conveying device is installed on the translation device, and the transfer belt portion 6 can transport the material upstream thereof to the transfer conveying device.

[0023] When the device is working, the material is transported above the main upper belt 2 of the main belt conveyor. The main upper belt 2 is provided with a transfer belt portion 6 which can change its position. When the transfer belt portion 6 is located at different positions, the material on the main upper belt 2 at that time can be cut off. When the material moves to the transfer belt portion 6, it is transferred to the transfer conveying device through the transfer belt portion 6. The transfer conveying device is used for midway unloading and stacking. The transfer conveying device is moved by the translation device so that the position of the transfer conveying device is adapted to the position of the transfer belt portion 6, thereby achieving the purpose of multi-point unloading and stacking.

[0024] refer to Figure 1 , Figure 3 , define the main upper belt 2 located upstream of the transfer belt portion 6 as the front belt portion, and the downstream as the rear belt portion, the transfer belt portion 6 includes an inclined belt portion 12 and a folded belt portion 11, one end of the inclined belt portion 12 is connected to the front belt portion, the other end is connected to the folded belt portion 11, the other end of the folded belt portion 11 is connected to the rear belt portion, a concave space 13 is formed between the folded belt portion 11 and the rear belt portion, and the material receiving part of the transfer conveying device is at least partially located in the concave space 13. The transfer belt portion 6 of the device is mainly composed of the inclined belt portion 12 and the folded belt portion 11. Through the above two parts, the material can lift the material of the front belt portion upward through the inclined belt portion 12, and then form a concave space 13 through the folded belt portion 11, so that the material can be thrown onto the material receiving part of the transfer conveying device.

[0025] Furthermore, a rotatable first roller 7 is installed between the inclined belt portion 12 and the folded belt portion 11, and a rotatable second stick 8 is installed between the folded belt portion 11 and the rear belt portion. The first roller 7 and the second stick 8 are installed on a translation device. Since the first roller 7 and the second stick 8 are installed on the translation device, when the translation device moves left and right, it can drive the first roller 7 and the second stick 8 to move left and right. Since the transfer belt portion 6 is formed by pulling the first roller 7 and the second stick 8, when the first roller 7 and the second stick 8 move left and right, the transfer belt portion 6 is moved left and right. In this way, the movement of the transfer belt portion 6 can be achieved through a simple structure.

[0026] Furthermore, a tensioning wheel can be provided on the folding belt portion 11. The tensioning wheel is installed between the translation device and the folding belt portion 11 through an elastic telescopic mechanism. The tensioning wheel is used to put the transfer belt portion 6 in a tensioned state with a certain rebound space. In this way, the transfer belt portion 6 can be in a tensioned state and can also make the transfer belt portion 6 move more smoothly.

[0027] The translation device includes a support track 3 arranged along the length direction of the main upper belt 2, a walking platform 9 that can walk on the support track 3, and a first roller 7 and a second stick 8 are rotatably installed on the walking platform 9. When the walking platform 9 walks on the support track 3, it drives the first roller 7, the second stick 8, and the transfer conveying device to move together. That is, the unloading and stacking points can be moved to the position where the walking platform 9 moves.

The transfer conveyor 5 and the diverter conveyor 4 are both installed on a translation device. The material conveying direction of the diverter conveyor 4 has an angle greater than zero with the movement direction of the main upper belt 2. The material of the front belt portion is conveyed to the transfer conveyor 5 through the inclined belt portion 12, and then the material is transferred to the diverter conveyor 4 through the transfer conveyor 5, and the material stacking and unloading are realized through the diverter conveyor 4.

[0030] As an embodiment of the material distributing mechanism 10, the material distributing mechanism 10 includes a vertically arranged material receiving cylinder 16, the bottom end of which is rotatably connected to a connecting cylinder 17, the bottom end of the connecting cylinder 17 has an eccentric cylinder 18 deviating from its rotation axis, and a rotating motor 15 is installed on the material receiving cylinder 16 to drive the connecting cylinder 17 to rotate.

[0031] When the device is working, the material is transported to the receiving barrel 16, and the connecting barrel 17 is driven to rotate by the rotating motor 15. Since the eccentric barrel 18 deviates from the rotation axis of the connecting barrel 17, when the connecting barrel 17 is at different working angles, the eccentric barrel 18 can be in different discharging orientations, so that multi-angle and multi-directional discharging can be achieved to meet the discharging needs.

[0032] The belt conveyor large span unloading device comprises at least two first conveyors 14, and the discharge end of the eccentric cylinder 18 can flow over a plurality of first conveyors 14. When the discharge end of the eccentric cylinder 18 is located above a first conveyor 14, the material can be distributed to the first conveyor 14, thereby achieving the purpose of distributing the material to the plurality of first conveyors 14.

[0033] Furthermore, the material distribution mechanism 10 includes a funnel 19 located below the eccentric cylinder 18, the funnel 19 has a storage channel 20 and at least two diversion channels 21 connected to the storage channel 20, each diversion channel 21 corresponds to a first conveyor 14, the funnel 19 can receive the material discharged by the eccentric cylinder 18, when it is necessary to distribute the material on multiple first conveyors 14 at the same time, the discharge part of the eccentric cylinder 18 is transferred to the funnel 19, the material enters the storage channel 20, and flows into different diversion channels 21 at the bottom of the storage channel 20, and then is diverted to different first conveyors 14, so as to achieve the purpose of distributing the material on multiple first conveyors 14 at the same time.

[0034] As an implementation mode, each diversion channel 21 is installed with a flow regulating valve 22, and the flow regulating valve 22 is used to adjust the discharge flow rate of the diversion channel 21 to achieve the purpose of distributing materials at different flow rates.
