AI Technical Summary
When the belt conveyor is damaged or under maintenance, the coal mining machine needs to be stopped, which affects normal production.
An emergency unloading device is installed on the belt conveyor, including a diverter plate and a telescopic cylinder. The diverter plate moves via outriggers and rails to divert coal and transport it out through other equipment during belt conveyor maintenance or repair.
This allows for continuous production of the coal mining machine without stopping the belt conveyor during maintenance or repair.

Abstract
Description
Technical Field
[0001] This invention relates to belt conveyors, and more specifically to an emergency unloading device for belt conveyors. Background Technology
[0002] Belt conveyors are widely used underground, serving to transport coal and tools. However, only one belt conveyor is typically installed at each work site to transport materials. When a belt conveyor breaks down or requires maintenance, the coal mining machine must be stopped for repair or maintenance, disrupting normal production. Summary of the Invention
[0003] The purpose of this invention is to provide an emergency unloading device for belt conveyors, which solves the problem that coal mining machines need to be shut down and normal production is affected when belt conveyors are damaged or under maintenance.
[0004] To achieve the above objectives, the technical solution adopted by this invention is as follows:
[0005] An emergency unloading device for a belt conveyor includes a conveyor belt, idlers, and a support frame. The idlers are mounted on the support frame via support rods, and the conveyor belt is mounted on the idlers. The device also includes a flow divider and a telescopic cylinder. The flow divider is positioned above the conveyor belt. Several legs are provided at the bottom of the flow divider, and each leg has a track wheel at its bottom. A track is connected to the support frame via connectors, and the track wheels are mounted on the track. The telescopic rod of the telescopic cylinder is connected to the legs, and the cylinder body is fixed to the support frame via fasteners. The cylinder is used to move the flow divider along the track's direction.
[0006] Furthermore, the flow divider has a first flow divider groove on one side and a second flow divider groove on the other side; and both the first flow divider groove and the second flow divider groove are placed downwards from the inside to the outside.
[0007] Furthermore, baffles are provided at both ends of the first and second diversion channels.
[0008] Furthermore, the connecting component is an I-beam.
[0009] Furthermore, it is equipped with a total of four support legs.
[0010] By adopting the above technical solution, the beneficial technical effects of the present invention are as follows:
[0011] This invention utilizes a diverter plate installed above the conveyor belt. When the conveyor belt requires maintenance, the coal mining machine delivers coal to the diverter plate, which then diverts the coal, ultimately transporting it out via a conveyor located at the diverter plate's outlet. After maintenance is completed, the telescopic rod retracts, moving the diverter plate and allowing the coal to fall back onto the conveyor belt, where it is then transported out by the conveyor. This invention enables the coal mining machine to operate without stopping during conveyor belt maintenance, ensuring operational efficiency. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of an emergency unloading device for a belt conveyor.
[0013] Figure 2 This is a schematic diagram of a manifold. Detailed Implementation
[0014] like Figure 1 As shown, an emergency unloading device for a belt conveyor includes a conveyor belt 1, idlers 2, and a support frame 3. The idlers 2 are mounted on the support frame 3 via support rods 4, and the conveyor belt 1 is mounted on the idlers 2. The device also includes a diverter plate 5 and a telescopic cylinder 6. The diverter plate 5 is positioned above the conveyor belt 1. Four legs 7 are provided at the bottom of the diverter plate 5, and each leg 7 has a track wheel 8 at its bottom. A track 9, which is an I-beam, is connected to the support frame 3 via a connector. The track wheels 8 are mounted on the track 9. The telescopic rod of the telescopic cylinder 6 is connected to the legs 7, and the cylinder body of the telescopic cylinder 6 is connected to the support frame 3 via a fixing member. The cylinder is used to drive the diverter plate 5 to move along the direction of the track 9, and the direction of the track 9 is the same as the transport direction of the conveyor belt.
[0015] When the belt conveyor is operating normally, the telescopic cylinder 6 is in the retracted state, causing the diverter plate 5 to move away from the unloading point. Coal mined by the coal mining machine falls directly onto the conveyor belt 1, which then transports the coal out. When the belt conveyor is damaged, such as when the idler roller 2 needs replacement, or when problems like belt tearing occur, the conveyor needs to be stopped for maintenance or repair. In this case, the telescopic rod is extended, positioning the diverter plate 5 below the unloading point. Coal mined by the coal mining machine falls onto the unloading point, and the coal is then transported again from there. For improved convenience, spare belt conveyors can be installed on both sides of the diverter plate 5, or technicians can push and pull the conveyor to transport the coal.
[0016] like Figure 2As shown, the diversion plate 5 has a first diversion trough 11 on one side and a second diversion trough 12 on the other side; both the first diversion trough 11 and the second diversion trough 12 are inclined downwards from the inside to the outside. Baffles 13 are provided at both ends of the first diversion trough 11 and the second diversion trough 12. Coal falls onto the diversion plate 5 and is diverted through the first diversion trough 11 and the second diversion trough 12, reducing transport pressure. After falling onto the diversion plate 5, the baffles 13 effectively prevent the coal from sliding out of the first diversion trough 11 and the second diversion trough 12. Under its own gravity, the coal slides down the first diversion trough 11 and the second diversion trough 12, allowing it to be transported out without passing through the original belt conveyor.
[0017] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
