[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a coal gangue transfer device for coal mine renovation, such as... Figures 1-4 As shown, the coal gangue transfer equipment for coal mine renovation includes: a conveyor belt body 1 for transferring coal gangue; a protective cover 2 installed outside the conveyor belt body 1, which is used to intercept dust during the transfer of coal gangue; a collection bucket 3 installed on one side of the conveyor belt body 1, which is connected to the protective cover 2 and is used to collect coal gangue, and a discharge hopper 4 is installed on the collection bucket 3; and a collection mechanism assembled on the collection bucket 3, which is used to collect dust generated during the unloading of coal gangue.

[0022] In this embodiment, the entire setup is installed in the corresponding position. When transporting coal gangue, the coal gangue is transported by the conveyor belt body 1. During the transport process, the protective cover 2 can intercept the dust generated during the transport of coal gangue, reducing the dust from flying. The conveyor belt body 1 transports the coal gangue into the collection bin 3. Subsequently, the coal gangue in the collection bin 3 can be transferred by a transport vehicle. When it is necessary to discharge the coal gangue in the collection bin 3, the collection mechanism is activated. The collection mechanism can collect the dust generated when the coal gangue is unloaded, further reducing dust from flying, effectively improving the working environment, reducing dust pollution, and preventing workers from inhaling large amounts of dust.

[0023] In a further preferred embodiment of the present invention, the collection mechanism includes: a collection box 5 disposed below the collection bucket 3, wherein a filter bag 6 for collecting dust is disposed inside the collection box 5; a negative pressure fan 7 fixedly installed on the outer wall of the collection box 5, wherein the air inlet end of the negative pressure fan 7 is connected to the collection box 5; and a connecting pipe 8 disposed on the collection box 5, wherein a collection cover 9 is connected to the connecting pipe 8, and the collection cover 9 is located on one side of the discharge hopper 4.

[0024] In this embodiment, when it is necessary to discharge the coal gangue in the collection bucket 3, the negative pressure fan 7 is started. At this time, a negative pressure environment is formed in the collection box 5. The coal gangue in the collection bucket 3 is discharged through the discharge hopper 4. The dust generated during unloading is sucked into the collection box 5 through the collection hood 9 and the connecting pipe 8, and then collected by the filter bag 6. This greatly reduces the spillage of dust during the unloading of coal gangue from the collection bucket 3, effectively improves the working environment, reduces the harm of dust to the health of workers, and also reduces dust pollution, which has good environmental benefits.

[0025] In a further preferred embodiment of the present invention, a water pump 10 is fixedly installed on the outer wall of the collection tank 3, and an installation pipe 11 is installed on the outer wall of the collection tank 3. The water outlet end of the water pump 10 is connected to the installation pipe 11, and an atomizing nozzle is provided on the installation pipe 11.

[0026] In this embodiment, the water inlet of the water pump 10 is connected to the corresponding water source pipeline. When it is necessary to discharge the coal gangue in the collection bucket 3, the water pump 10 is started. The water pump 10 pumps water to the installation pipe 11, and then sprays out fine water mist through the atomizing nozzle on the installation pipe 11. This water mist can fully contact the dust in the surrounding air, making the dust particles wet and heavier, accelerating the settling, thereby further reducing the dust concentration in the working environment.

[0027] In a further preferred embodiment of this utility model, the collecting bucket 3 is provided with a discharge mechanism, which is used to discharge the coal gangue collected in the collecting bucket 3. The discharge mechanism includes: a feeding auger 13 rotatably installed in the collecting bucket 3, one end of the feeding auger 13 extending into the feeding hopper 4; and a first servo motor 12 fixedly installed on one side of the outer wall of the collecting bucket 3, the output shaft of the first servo motor 12 being connected to one end of the feeding auger 13 through a coupling.

[0028] In this embodiment, when it is necessary to discharge the coal gangue in the collection bucket 3, the first servo motor 12 is started. The output shaft of the first servo motor 12 drives the feeding auger 13 installed in the collection bucket 3 to rotate through the coupling. As the feeding auger 13 rotates, the coal gangue collected in the collection bucket 3 can be transported to the feeding hopper 4 in an orderly manner for discharge, so as to realize the smooth discharge of coal gangue.

[0029] In a further preferred embodiment of this utility model, two mounting shafts 14 are symmetrically and rotatably mounted on the collection box 5. A cam 15 is fixedly sleeved on each of the two mounting shafts 14. The two cams 15 are located on both sides of the filter bag 6. A driving mechanism is provided on the collection box 5 and the two mounting shafts 14. The driving mechanism is used to drive the two cams 15 to rotate and vibrate the filter bag 6 to discharge the material.

[0030] In this embodiment, when cleaning the dust collected inside the filter bag 6, after most of the dust has been cleaned, some dust may still remain on the inner wall of the filter bag 6. At this time, the drive mechanism is activated, which drives the two mounting shafts 14 to rotate, thereby causing the cam 15 fixedly mounted on the mounting shafts 14 to rotate. During the rotation of the cam 15, it will periodically strike the filter bag 6, causing the filter bag 6 to vibrate. The dust attached to the filter bag 6 will fall off under the action of vibration, improving the cleaning effect of the filter bag 6. At the same time, the staff can also open the sealed door on the rear side wall of the collection box 5 according to actual needs, take out the filter bag 6 for cleaning, and operate according to actual needs.

[0031] In a further preferred embodiment of the present invention, the driving mechanism includes: a second servo motor 16 fixedly installed on the outer wall of one side of the collection box 5, the output shaft of the second servo motor 16 being connected to one end of one of the mounting shafts 14 via a coupling; and two synchronous pulleys 17 respectively fixedly sleeved on the two mounting shafts 14, with a synchronous belt 18 sleeved on the two synchronous pulleys 17.

[0032] In this embodiment, when using the drive mechanism, the second servo motor 16 is started. The output shaft of the second servo motor 16 drives one of the mounting shafts 14 to rotate. Under the action of the two synchronous pulleys 17 and the synchronous belt 18, the two cams 15 on the two mounting shafts 14 are driven to rotate. The cams 15 periodically strike the filter bag 6, causing the filter bag 6 to vibrate. The dust adhering to the filter bag 6 falls off under the action of vibration, improving the cleaning effect of the filter bag 6.

[0033] In a further preferred embodiment of the present invention, a cleaning pipe is provided at the bottom of the collection box 5, and the cleaning pipe is connected to the bottom of the filter bag 6.

[0034] In this embodiment, when cleaning the dust collected inside the filter bag 6, the control valve on the cleaning pipe can be opened for cleaning.

[0035] In summary, compared with related technologies, this device can effectively transport coal gangue, reduce dust generation during transport, improve the working environment, and reduce dust pollution.

[0036] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
