[0001] The present invention relates to the technical field of mining machinery, and in particular to an automatic slag discharge system and drilling equipment. Background Art

[0002] Traditional drilling equipment, such as a shaft drilling rig, needs to be equipped with a water reservoir to store the slag water from the shaft when conducting the pilot hole operation. The slurry water is pumped into the machine head by a water pump after sedimentation to be used for the pilot hole slag return so as to be recycled. The construction of a water reservoir often occupies a large area and is difficult to construct. Especially when encountering a shaft construction project with a small depth, the drilling rig has a short construction period to drill a well and needs to be moved frequently. At this time, it is time-consuming and labor-intensive to configure a water reservoir for each shaft, which is not economical. In addition, when the shaft drilling rig is conducting the pilot hole operation, it is necessary to manually shovel away the slag stone that comes up from the hole mouth regularly to prevent the slag stone from accumulating at the hole mouth, and it is highly dependent on manual labor.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0035] Reference Figures 1 to 4 An automatic slag discharge system according to an embodiment of the present invention comprises: a slag guiding structure 100, a pumping device 300 and a sand removal device 200. The slag guiding structure 100 is sleeved on the outer periphery of the drill pipe. The inlet end of the pumping device 300 is connected to the slag guiding structure 100, and the outlet end is connected to the sand removal device 200. The pumping device 300 is used to pump the slurry water generated by the drill pipe guide hole and the crushed slag contained in the slurry water in the slag guiding structure 100 into the sand removal device 200.

[0036] Furthermore, the pumping equipment 300 is a slurry pump, and the sand removal equipment 200 is a cyclone desander. The slurry pump is a centrifugal pump, which is mainly used to transport mud media with a high sand content and has a certain self-priming ability; after the slurry pump pumps the slurry water into the cyclone desander, the slurry water swirls at high speed in the cyclone desander. Under the combined action of centrifugal force and gravity, sand and gravel sink to the bottom of the cyclone and are discharged regularly from the bottom slag discharge port. The filtered clean water returns to the drill pipe through the water outlet at the top of the cyclone desander through the return pipe, thereby realizing recycling. The cyclone desander discharge port is equipped with an automatic gate valve, which can control the opening time regularly. When the automatic gate valve is opened, sand and gravel are discharged from the slag discharge port under the action of the internal water pressure of the cyclone desander. Both the slurry pump and the cyclone desander are existing equipment available on the market. They only need to be purchased according to actual needs, and will not be described in detail in this application.

[0040] It should be noted that the transition pipe 150 is not connected to the annular groove 120, and the annular groove 120 and the center hole 110 can only be connected through the through hole 141, that is, the water in the annular groove 120 can only enter the center hole 110 through the through hole 141, and then the water in the center hole 110 is pumped out through the first pumping hole.

[0041] Furthermore, the outer ring wall 130 is provided with a water pumping pipe 131 extending in the radial direction of the outer ring wall 130, one end of the water pumping pipe 131 is connected to the second water pumping hole, and the other end is connected to the pumping device 300.

Specifically, the plurality of strip holes 161 is provided to facilitate water overflow, so as to prevent the water level in the ring groove 120 from being too high, resulting in excessive pressure in the ring groove 120 and damaging the slag guiding structure 100. The water supply pipe 162 is fixed on the cover plate 160, and the end of the water supply pipe 162 is connected to a water supply device for supplying water to the ring groove 120, and the water supply device can be a water pump or other equipment.

A through hole for the drill rod to pass through is arranged in the center of the sealing ring 170. The through hole is in sealing contact with the outer surface of the drill rod to prevent water in the center hole 110 from flowing out from the connection between the sealing ring 170 and the drill rod.
