Description

Technical Field

[0001] The present invention relates to the technical field of coal mining equipment, and in particular to a fully mechanized intelligent top coal caving equipment. Background Art

[0002] Existing top coal caving equipment for fully mechanized mining faces includes a shearer, hydraulic supports, a shearer-hydraulic support relative positioning device, a support controller, a support server, and a solenoid valve driver. The shearer-hydraulic support relative positioning device includes a central system processing unit and an infrared sensor. The infrared sensor consists of an infrared transmitter mounted at the center of the shearer and infrared receivers mounted on each hydraulic support. Each infrared receiver, support controller, support server, and solenoid valve driver communicate with the central system processing unit via wireless industrial Ethernet. Each hydraulic support is a low-level top coal caving hydraulic support with a tail beam and a sprag mechanism. The tail beam and sprag mechanism includes a tail beam, a tail beam inclination adjustment hydraulic cylinder, a sprag, and a sprag extension and retraction hydraulic cylinder. Infrared receivers mounted on each hydraulic support sequentially receive infrared signals and transmit them to the support controller. The support controller reports the shearer's position information to the support server. The support server determines the shearer's position and transmits this information to the monitoring host. The monitoring host monitors the supports according to a pre-programmed procedure, determining coal caving instructions based on the position of the shearer and sending these instructions to the support server. The support server receives these instructions and transmits them to the support controller. The support controller, in response to these instructions, controls the solenoid valve drivers to open the corresponding solenoid valves, completing the hydraulic support movement, raising and lowering, and coal caving. Under the control of the central system processing unit, the support server, and the support controller, coal caving is performed using a first-round roughing-out followed by a second-round catch-up. The 10th support behind the shearer begins the first round of caving, which lasts no longer than 25.5 seconds. Simultaneously, the 15th support behind the shearer begins the second round of catch-up caving, which lasts no longer than 25.5 seconds. Existing top coal caving equipment in fully mechanized mining faces uses a clock-based program to control the swing of the tail beam and the extension and retraction of the inserts in a sequential order. During coal caving, if there is gangue blocking the tail beam, both the swing of the tail beam and the extension of the inserts may be hindered. It is easy for the tail beam and the inserting plate to fail to perform the action properly, that is, the problem of carrying out the next action procedure, which affects the smooth progress of coal placement.

[0003] Utility model patent publication number CN213953634U discloses a novel top coal caving equipment for fully mechanized mining working faces. The equipment comprises a shearer, a hydraulic support, a shearer-hydraulic support relative positioning device, a support controller, a support server, and a solenoid valve driver. Each hydraulic support is equipped with a tail beam and splice plate caving mechanism. The tail beam and splice plate caving mechanism comprises a tail beam, a tail beam inclination adjustment hydraulic cylinder, a splice plate, and a splice plate extension hydraulic cylinder. The splice plate extension hydraulic cylinder is equipped with a splice plate travel sensor. The tail beam is equipped with a tail beam inclination sensor, both of which are connected to a central system processing unit. The splice plate travel sensor is an electromagnetic proximity switch located at the front of the tail beam and at the rear of the splice plate. When the splice plate reaches its front stop, the electromagnetic proximity switch is triggered. This utility model can promptly detect and resolve faults such as improper tail beam or splice plate movement, making it suitable for fully mechanized top coal caving operations. However, this technical solution does not allow for coal sorting during transportation or dust reduction, which is detrimental to worker health. Summary of the Invention

[0029] The working principle of the comprehensive mining intelligent top coal caving equipment disclosed in the present invention is: the mined coal is placed on the receiving trough 201. In order to prevent the distance between the discharge position and the receiving trough 201 from being too high and causing excessive impact on the receiving trough 201, thereby causing damage, a third electric cylinder 302 is set between the receiving trough 201 and the supporting platform 301. The third electric cylinder 302 is used to control the height of the receiving trough 201 and thus adjust the distance between the receiving trough 201 and the discharge position. In order to adapt to the height change of the receiving trough 201 and ensure that the coal flowing out of the discharge trough 208 falls accurately on the second conveyor belt 105, a second electric cylinder 209 is set between the receiving trough 201 and the bottom of the discharge trough 208. The second electric cylinder 209 is used to adjust the angle between the discharge trough 208 and the receiving trough 201. The coal falling on the receiving trough 201 is captured by the camera 203 to identify whether it is coal or coal gangue.

[0030] If the falling coal is coal, start the first electric cylinder 205, and the first electric cylinder 205 drives the push plate 202 to slide inside the receiving trough 201 through the connecting rod 204, and pushes the coal inside the receiving trough 201 from the discharge trough 208 to the second conveyor belt 105, and is transported by the second conveyor belt 105; if the falling coal is gangue, first start the flip motor 210, and the flip motor 210 drives the flip plate 211 to rotate, and the flip plate 211 blocks the entrance of the discharge trough 208, and opens the discharge pipe 212 at the same time, and then start the first electric cylinder 205, and the push plate 202 drives the gangue to fall from the discharge pipe 212 onto the two first conveyor belts 102, and is transported by the first conveyor belt 102, thereby realizing the classification of coal and gangue.

[0031] When the first electric cylinder 205 is started, the first electric cylinder 205 drives the piston inside the piston cylinder 402 to slide through the connecting rod 204 and the piston cylinder 402. The piston compresses the gas inside the water tank 403, so that the water in the water tank 403 flows out through the water outlet pipe 406. There are two water inlets at both ends of the slide bar 501. At this time, there are two situations. When the flip plate 211 does not flip, one water inlet on the slide bar 501 is connected to the second branch pipe 409, and the water in the water tank 403 is transported to the first nozzle 207 through the water outlet pipe 406, the second branch pipe 409, and the first water pipe 405 to be sprayed out to reduce dust on the coal on the discharge trough 208; when the flip plate 211 does not flip, one water inlet on the slide bar 501 is connected to the second branch pipe 409. When 211 flips, the rotating shaft of the flip plate 211 drives the second pulley 502 to rotate, and the second pulley 502 drives the third pulley 506 to rotate through the second belt 503, and the third pulley 506 drives the rotating shaft 505 to rotate, and the rotating shaft 505 drives the driving rod 504 to swing, and the driving rod 504 drives the slide bar 501 to slide through the pin shaft inside the slide bar 501, so that the water inlet hole at the other end of the slide bar 501 is connected to the first branch pipe 407. At this time, the water in the water tank 403 is transported to the second nozzle 213 through the outlet pipe 406, the first branch pipe 407, the second water pipe 408, and the third water pipe 410 to be sprayed out, thereby realizing the dust reduction operation on the coal gangue.
