Description

Technical Field

[0001] The utility model relates to the technical field of automatic cleaning of floating coal at the tail roller of a continuous digging belt conveyor, in particular to an automatic cleaning device for floating coal at the tail roller of a continuous digging belt conveyor. Background Art

[0002] The tail drum of a continuous belt conveyor is equipped with a collection trough for collecting loose coal. Over time, this loose coal accumulates. If not promptly removed, it can rub against the belt and cause fires. Crusher operators are required to promptly remove this loose coal. However, cleaning this area while the belt is running can easily lead to safety accidents, while stopping the belt for cleaning disrupts normal production. Therefore, there is an urgent need for a cleaning device that can remove this loose coal while the belt is running without causing safety accidents. Utility Model Content

[0003] The purpose of the utility model is to provide an automatic cleaning device for floating coal at the tail roller of a continuous excavator belt conveyor. By arranging a cylinder on the side of the collection trough, the cylinder can drive a push plate to move along the collection trough through a push rod to automatically clean the floating coal in the collection trough, so as to achieve the purpose of automatic cleaning and avoid the occurrence of manual safety accidents.

[0004] The utility model provides an automatic cleaning device for floating coal at the tail roller of a continuous belt conveyor, which comprises:

[0005] Collection tank,

[0006] A cylinder, arranged on the side of the collecting tank;

[0007] a connecting plate connected to the telescopic end of the cylinder;

[0008] A push rod connected to the connecting plate, wherein the end of the push rod is provided with a push plate;

[0009] When the telescopic end of the cylinder is retracted, it can drive the push rod to move along the collecting trough, and the push plate can push out the floating coal in the collecting trough for cleaning.

[0010] Preferably, the cylinder is installed on the side wall of the collecting tank.

[0011] Preferably, the telescopic direction of the cylinder is consistent with the extending direction of the push rod.

[0012] Preferably, the connecting plate includes a connecting surface, and the telescopic end of the cylinder and the push rod are both connected to the connecting surface.

[0013] Preferably, the cylinder and the push rod are perpendicular to the connecting surface.

[0014] Preferably, a support sleeve is provided on the bottom wall of the collecting tank, and the push rod is sleeved in the support sleeve.

[0015] Preferably, a spray device is provided in the collecting tank, and the spray device is used to spray water to clean the collecting tank after the push plate pushes the floating coal in the collecting tank.

[0016] Preferably, spray devices are provided on both sides of the collecting trough in the extension direction.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model uses a pneumatic cylinder as the driving mechanism. First, the cylinder can directly utilize the underground compressed air pipeline as its air source and can be directly placed on the wall of the collection tank, eliminating the need for additional space. The cylinder can directly drive the push plate to move along the collection tank to automatically remove floating coal, thereby reducing the number of manual cleaning operations and improving production efficiency and safety.

[0019] 2. The present invention employs a cylinder retracting to drive the push plate to clear floating coal. This reduces the space required for placement along the push rod's extension direction. Furthermore, as the push rod moves, the amount of floating coal accumulated on the push plate gradually increases, increasing the resistance to movement. With this method, the cylinder's telescopic length gradually decreases as the push rod moves, minimizing the risk of damage to the cylinder, ensuring safe operation.

[0020] 3. In the present invention, after the cylinder drives the push plate to automatically clean the floating coal, the floating coal in the collection tank is cleaned by spraying, which can also have a cooling effect to reduce the risk of subsequent floating coal accumulation and belt friction causing fire.

[0024] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] Example 1

[0026] Combine Figure 1 This embodiment provides an automatic cleaning device for floating coal at the tail drum of a continuous excavator belt conveyor. The device includes a collection trough 6, with a cylinder 1 positioned on the side of the collection trough 6. In a specific embodiment, the operating pressure of the cylinder 1 is 0.4MP-4MP (the underground air pressure is between 0.6MP-1.5MP), and the underground air pressure can meet the operating pressure requirements of the cylinder 1. The telescopic end of the cylinder 1 is connected to a connecting plate 2, to which a push rod 4 is further connected. The other end of the push rod 4 is provided with a push plate 5. When the telescopic end of the cylinder 1 is retracted, it can drive the push rod 4 to move along the collection trough 6. The push plate 5 can push the floating coal in the collection trough 6 out for cleaning.

[0027] In one specific embodiment, the collection trough 6 is made of 8mm steel plate, and the push plate 5 is welded from 8mm steel plate to a 6-inch steel pipe, connected to the SC63*1000mm cylinder 1. The cylinder 1 and push rod 4 are arranged parallel to each other. When the cylinder 1 extends, the push rod 4 moves out of the collection trough 6. When the cylinder 1 retracts, the push rod 4 moves into the collection trough 6 and drives the push plate 5 to push out the floating coal within the trough for cleaning. This operating mode not only allows the cylinder 1 to be positioned directly within the wall of the collection trough 6, saving space, but also protects the cylinder 1. Specifically, if the cylinder 1 and push rod 4 are arranged coaxially, the extension of the telescopic end of the cylinder 1 drives the push rod 4 toward the collection trough 6, which in turn pushes the push plate 5. In this case, the total length of the telescopic end of the cylinder 1 and the push rod 4 in the extended direction is large, increasing the risk of damage to the telescopic end of the cylinder 1. This arrangement of the cylinder 1 in this embodiment not only saves space but also protects the cylinder 1. In this embodiment, the maximum push-pull length of the cylinder 1 is 1.2 m.

[0028] In a specific embodiment, the connecting plate 2 can be a rectangular metal plate, and the connecting plate 2 includes a connecting surface. The telescopic end of the cylinder 1 and the push rod 4 are both connected to the connecting surface. The telescopic end of the cylinder 1 and the push rod 4 are both perpendicular to the connecting surface and the connection positions are at the same height.

[0029] A support sleeve 3 is provided on the bottom wall of the collecting tank 6, and the push rod 4 is sleeved in the support sleeve 3. The support sleeve 3 can guide the extension direction of the push rod 4, thereby preventing the push plate 5 from deviating and abutting against the tank wall of the collecting tank 6, which may cause damage to the cylinder 1, thereby ensuring safe use.

[0030] In this embodiment, a spray device 7 is provided within the collection trough 6. The spray device 7 is used to spray water to clean the collection trough 6 after the push plate 5 pushes the floating coal out of the collection trough 6. Spray devices 7 are provided on both sides of the collection trough 6. The spray devices 7 not only clean the collection trough 6 but also reduce its temperature to prevent fire accidents.

[0031] In a specific embodiment, a compressed air pipeline connected to the cylinder 1 is provided with a compressed air pipeline solenoid valve, and a spray pipeline connected to the spray device 7 is provided with a spray pipeline solenoid valve. The spray pipeline solenoid valve and the compressed air pipeline solenoid valve are connected to the auxiliary contacts of the cycle time relay, and the cycle time of the time relay is set to 10 minutes, with a delay of 30 seconds. That is, the time relay is activated once every ten minutes, and the activation time is 30 seconds. When the cycle time relay is activated, the auxiliary contacts are closed, the spray pipeline solenoid valve and the compressed air pipeline solenoid valve are energized and activated, the compressed air pipeline is connected, the cylinder 1 is activated and drives the push plate 5 to push out the floating coal accumulated in the collection tank 6, and at the same time the water supply pipeline is connected, and the spray device 7 sprays water to clean the collection tank 6. The cycle time relay is closed at the set time, the cylinder 1 is retracted to drive the coal shoveling plate to retract, and the spray stops spraying water. The cycle continues in this way. This device has changed the previous manual method of cleaning floating coal, and through on-site trials underground, it has effectively reduced the number of times personnel clean floating coal, reduced the labor of workers, and eliminated the safety hazard of fire caused by excessive accumulation of floating coal and friction with the belt during the production process. The safety of employees is guaranteed, and the goal of reducing staff and increasing efficiency is achieved.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
