[0003] When traditional exploration drilling equipment is used for oil and gas exploration, when it is used for drilling in different exploration surfaces, the drilling surface is affected by the drilling of its broken drilling structure, and a certain amount of fragments and waste will be generated. In addition, when drilling on the surface of the rock layer, the surface of the rock layer is prone to sputtering during drilling. The splashing and accumulation of fragments hinder its drilling work and cause sputtering risks to the surrounding environment. Utility Model Content

[0026] When the device is used for drilling cuttings processing in oil and gas exploration, the first connecting cover 1 and the second connecting cover 2 are spliced ​​and installed so that the device surrounds the drilling position on the rock surface. When the drilling mechanism drills the rock surface through the openings on the tops of the first connecting cover 1 and the second connecting cover 2, the fragments generated by the drilling can enter the interior of the collecting cover 3. After being quantitatively generated, the fragments will enter the interior of the collecting cover 3, and then the stepping motor 5 on the driving seat 4 can be powered on, and its output end can drive the rotation of the driving gear 6. The guide ring 8 can rotate inside the first connecting cover 1 and the second connecting cover 2 with the assistance of the rotation of the steering ring 7. Through the meshing connection between the guide ring 8 and the driving gear 6, the guide ring 8 and the inclined scraper 9 can be driven to rotate by the rotation of the driving gear 6, and then the inclined scraper 9 can move the fragments inside the collecting cover 3 after rotation, so that they can be output through the discharge notch 16, so as to reduce the accumulation and obstruction of rock fragments on the drilling position.

[0027] A positioning groove 12 is provided inside the second connection cover 2, and the steering ring 7 penetrates and slides inside the positioning groove 12;

[0028] The positioning groove 12 can cooperate with the rotation of the steering ring 7 without affecting the disassembly between the first connecting cover 1 and the second connecting cover 2.

[0029] The bottom of the inner wall of the collecting cover 3 is fixedly installed with an inclined bottom plate 13, and the bottom of the inclined bottom plate 13 is tightly fitted with the bottom of the inclined scraper 9. The inclined bottom plate 13 is annular, and the structural height of the inclined bottom plate 13 increases from the inside to the outside. The front end and the rear end of the facing surface of the first connecting cover 1 and the second connecting cover 2 are staggeredly installed with docking blocks 14, and the docking blocks 14 are plugged into each other with the first connecting cover 1 and the second connecting cover 2;

[0030] By means of the inclination of the inclined bottom plate 13 , the rock fragments can be more easily stacked inside the collecting cover 3 for subsequent discharge work.

[0032] The tops of the first connection cover 1 and the second connection cover 2 are both provided with a docking groove 10, and a counterweight block 11 is clamped on the top of the docking groove 10;

[0033] By clamping the counterweight block 11 with the docking groove 10 , the tightness and stability of the connection between the first connection cover 1 and the second connection cover 2 can be increased.

[0034] A guide roller 15 is fixedly mounted on the top of the inclined scraper 9, and the guide roller 15 is rollingly connected to the inner wall of the collection cover 3;

[0035] The guide roller 15 can be rotated in the collecting cover 3 to assist the rotation of the inclined scraper 9, thereby increasing the stability of the inclined scraper 9 in rotation.

[0036] Working principle: When the device is in use, the first connecting cover 1 and the second connecting cover 2 are spliced ​​and installed to surround the top of the drilling position. The rock debris generated during the drilling process can enter the interior of the collecting cover 3. By energizing the stepping motor 5, its output end can drive the rotation of the driving gear 6, and then assist the rotation of the steering ring 7 and the guide ring 8, so that it drives the inclined scraper 9 to move and scrape the debris in the collecting cover 3, so that it can be discharged through the discharge notch 16, so as to achieve the purpose of pushing the debris in the collecting cover 3 out.
