Problems solved by technology

[0002] The drilling machine is powered by gasoline hydraulic pressure, which converts the hydraulic power into mechanical force to break rocks. After the drilling rig starts to take the coring work, it needs to continuously inject water into the drill pipe. First, it reduces dust and second, it has a cooling effect. When the first drill pipe is rotated, the hydraulic motor should be stopped to disengage the joint from the drill pipe, and then the second drill pipe should be connected. According to this cycle, the coring work of the tunnel is completed. When drilling, due to the large amount of water given during drilling, the water enters the hole along with the connection gap of the drill pipe joint, and the liquid water mixed with dust enters the hole. If the hole is not cleaned in time when the drill pipe is added, it is easy to Drilling stop accidents occur, and most of the existing holes are cleaned by water injection and impact cleaning. The liquid mixture solidified on the inner wall of the hole needs to consume a lot of water resources and the cleaning effect is not very good.

Embodiment 1

[0027] Such as Figure 1-Figure 4 As shown, the present invention provides a tunnel coring drilling machine, the structure of which includes a hydraulic motor 1, a machine head 2, a joint 3, a drill bit 4, a support rod 5, an installation shaft 6, and a fixed base 7. The hydraulic motor 1 is installed At the upper end of the machine head 2, the machine head 2 is fixed together with the support rod 5 through the mechanically connected installation shaft 6, and the bottom of the support rod 5 is vertically welded on the fixed base 7, and the bottom of the machine head 2 is set There is a joint 3 and a drill bit 4, and the interior of the joint 3 is composed of a supporting end 31 and an engaging end 32, wherein the joint 3 and the connecting rod are mechanically connected by the engaging end 32, and the supporting end 31 is located at the joint 3 close to the machine head 2, the support end 31 is equipped with a connecting turntable 311 and a mounting seat 312, a spring shaft 31...

Embodiment 2

[0029] Such as Figure 5-Figure 6 As shown, on the basis of Example 1, the scraper assembly 15c consists of a soft scraper c1, an arched disc c2, a slide table c3, a sliding walking piece c4, and a negative pressure port c5. The soft scraper c1 It is fixed on the arched disc c2, and the openings at both ends of the arched disc c2 are connected to the negative pressure port c5 through the slide table c3 and communicated with the inside. The slide table c3 is driven by the sliding walking part c4, and the sliding walking part c4 Drive the sliding table c3 to move along the horizontal rails on both sides of the carrier 15a, and there are fine holes in the gaps between the adjacent soft scrapers c1 that are in contact with the bristles 15b. The disk c2 communicates with the interior, the output port of the negative pressure port c5 is connected to the bearing cavity of the carrier 15a, the tip of the soft scraper c1 is tapered, which improves the penetration force between the bris...

Abstract

The invention discloses a tunnel coring drilling machine. The tunnel coring drilling machine structurally comprises a hydraulic motor, a machine head, a joint, a drill bit, a supporting rod, an installation shaft and a fixing base. The hydraulic motor is installed at the upper end of the machine head. The machine head is fixed to the supporting rod together through the mechanically-connected installation shaft. The bottom of the supporting rod is vertically welded to the fixing base. The joint and the drill bit are arranged at the bottom of the machine head. The inside of the joint is composedof a supporting end and a connecting end. The joint and a connecting rod are mechanically connected through the connecting end. The supporting end is located at the end, near the machine head, of thejoint. The inner wall of a hole of the joint is scrubbed through an arranged rotary type scrub-away mechanism and cooperation with high-pressure water flushing, the contact area of the bristles and the inner wall is greatly increased through the combined action of soft bristles and hard bristles, and a mixture solidified on the inner wall of the joint is thoroughly eliminated.
