Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine drilling, relates to drill slag, and specifically relates to a drill slag transfer vehicle for underground coal mine drilling construction. Background Art

[0002] In soft and protruding coal seams, compressed air is usually used as a slag removal medium during drilling construction. The compressed air enters the bottom of the hole from the center hole of the drill pipe and carries the drill cuttings out of the borehole. Since soft and protruding coal seams have a high gas content and soft coal quality, the amount of drill cuttings returned from the hole is large. The current solution is to install a hole mouth device at the borehole mouth, and the drill cuttings will naturally fall and accumulate from the slag outlet of the hole mouth device. After the drilling construction is completed, the drill cuttings will be manually collected and loaded into a belt conveyor or transfer vehicle. This method of collecting drill cuttings has the problems of high labor intensity, poor working conditions, and low production efficiency. In addition, since the compressed air returned from the hole has a certain pressure, the coal powder suspended in the compressed air also has a great impact on the drilling site environment. Currently, a water mist dust suppression device is installed at the slag outlet of the hole mouth device, but the effect is not ideal. Summary of the Invention

[0085] like Figure 6 As shown, a plurality of supports 503 are evenly fixedly connected to the four sides of the bottom of the transfer box 5 . The supports 503 correspond to the ear seats 104 one by one, and each ear seat 104 is connected to the support 503 by a latch.

[0086] In this embodiment, the H-shaped frame 501 is used to support the slag inlet shell 603 in the slag inlet pipeline 6.

[0087] In this embodiment, the drill cuttings in the transfer box 5 can fall into the slag discharge shell 403 through the material discharge hole 502 at the bottom of the box.

[0088] In this embodiment, the corner of the support 503 is an arc structure. When the slag discharge pipe 4 at the bottom of the transfer box 5 needs to be repaired, the latch on one side of the bottom of the transfer box 5 can be removed, and the transfer box 5 can be rotated 90 degrees around the pin on the other side to clear the space above the slag discharge pipe 5.

[0089] As a preferred solution of this embodiment, Figures 7 to 9As shown, two rectangular limiting plates 504 are provided on the inner side of the bottom of the transfer box 5.

[0093] A rear cover 510 that can be opened or closed is provided on the rear wall of the transfer box 5 .

[0094] In this embodiment, transfer box 5 stores drill cuttings. When the construction site is ready for drill cuttings transfer, the cuttings are transferred to transfer box 5 via the cuttings inlet pipeline 6. The cuttings are then transferred to a discharge point via the cuttings discharge pipeline 4. If the construction site is not ready for drill cuttings transfer, the cuttings are transferred to transfer box 5 via the cuttings inlet pipeline 6. Once the construction site is ready for drill cuttings transfer, the cuttings are transferred to a discharge point via the cuttings discharge pipeline 4.

[0095] In this embodiment, when the drill cuttings inside the transfer box 5 are glued together due to long-term stacking or other reasons, the drill cuttings can be cleaned by opening the front cover 509 or the rear cover 510 .

A slag feed pipeline motor 604 is provided on the left side wall of the slag feed shell 603. The slag feed pipeline motor 604 drives the slag feed spiral steel belt 602 through the first connecting shaft 605 of the slag feed pipeline.

[0100] like Figure 12 As shown, the right end of the slag feed pipeline conveying pipe 601 is coaxially mounted with a slag feed port shell 606. The interior of the slag feed port shell 606 is hollow and the top and left end are open. The left end of the slag feed port shell 606 is fixedly connected to the right end of the slag feed pipeline conveying pipe 601. A rotatable second slag feed pipeline connecting shaft 607 is horizontally provided on the inner side of the right side wall of the slag feed port shell 606. The second slag feed pipeline connecting shaft 607 is connected to the right end of the slag feed spiral steel belt 602.

[0101] In this embodiment, the composition and working principle of the slag inlet pipeline 6 are similar to those of the slag discharge pipeline 4. The top of the slag inlet shell 606 is open and is located below the outer side of the drill hole. It collects the drill cuttings returned from the hole and then transports them to the drill cutting inlet shell 603 through the slag inlet pipeline feed pipe 601. The drill cuttings then fall into the transfer box 5 from the bottom of the drill cutting inlet shell 603.

[0102] As a preferred solution of this embodiment, the length of the slag feeding spiral steel belt 602 is greater than the distance between the first connecting axis 605 and the second connecting axis 607 of the slag feeding pipeline.

[0103] Except for the fixed positions at both ends, the bottom of the slag feeding spiral steel belt 602 is in contact with the inner wall of the slag feeding pipeline 601.

[0104] like Figure 12 As shown, the cross-sectional area of ​​the inner cavity of the slag inlet pipeline conveying pipe 601 is smaller than or equal to the area of ​​the right end opening of the slag inlet shell 603 .

[0105] like Figure 12As shown, the cross-sectional area of ​​the inner cavity of the slag inlet pipeline conveying pipe 601 is smaller than or equal to the area of ​​the left end opening of the slag inlet shell 606 .

[0106] The specific use process of the device in this utility model is as follows:

[0107] Before drilling construction, an orifice device will be installed at the borehole mouth (the orifice device does not fall within the scope of protection of the present utility model). A dust removal connection port is provided at the upper end of the orifice device for the compressed air mixed with coal powder returned from the diversion hole, and a slag outlet is provided at the lower end of the orifice device for the drill slag returned from the diversion hole.

[0108] The drill cuttings transfer vehicle is arranged in the drilling site, and the dust collector 8 is connected to the dust removal connection port of the orifice device, so that the compressed air through-hole dust collector containing coal powder returned from the hole can remove the coal powder; the support arm 7 is used to support the slag inlet pipeline 6, and the slag inlet shell 606 in the slag inlet pipeline 6 is moved to the bottom of the slag outlet of the orifice device under the movement of the crawler vehicle body 1, so that the drill cuttings can fall into the slag inlet shell 606 after falling out of the slag outlet. The drill cuttings are transported to the slag inlet shell 603 under the rotation of the slag inlet spiral steel belt 602, and then fall into the transfer box 5 from the bottom opening of the slag inlet shell 603. The insert plate 506 at the lower part of the transfer box 5 is located at the outermost end. At this time, the insert plate material feeding hole 508 coincides with the box bottom feeding hole 502 at the bottom of the transfer box 5. The drill cuttings fall into the slag discharge shell 403 of the slag discharge pipeline 4 through the box bottom feeding hole 502 at the bottom of the transfer box 5. The drill cuttings are transported to the slag discharge port shell 406 under the rotation of the slag discharge spiral steel belt 402, and then fall into the belt conveyor or transfer vehicle from the opening at the bottom of the slag discharge port shell 406.

[0109] When the conveyor belt or transfer vehicle is full, the insert plate 506 is pushed to the innermost end so that the insert plate material feeding hole 508 does not overlap with the box bottom material feeding hole 502 at the bottom of the transfer box 5. The drill cuttings are transferred to the transfer box 5 for temporary storage. After the conveyor belt or transfer vehicle is emptied, the drill cuttings in the transfer box 5 are transferred to the conveyor belt or transfer vehicle.
