Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, specifically to a rotary drilling device for breaking up surface rocks in oil extraction. Background Technology

[0002] Petroleum appears as a black, viscous substance with a distinctive odor and a certain degree of fluidity. It is less dense than water and insoluble in water, and it floats on the surface of water year-round. Its main components are hydrocarbons, and most of it is buried deep at the bottom of the water. When isolated from air, it is oxidized and decomposed, forming petroleum raw materials under certain temperature and pressure conditions.

[0003] To drill mine shafts or pumping wells on the surface, a rotary drilling rig is required to drill vertically above the surface. However, such equipment often lacks a sturdy limiting structure during the lifting and lowering process. If the drilled hole tilts, it will hinder subsequent drilling and exploration underground.

[0004] Now, a new type of oil extraction method using a surface rock breaking rotary drilling device is proposed to solve the above problems. Utility Model Content

[0007] As a further technical solution of this utility model, the top of the output end of the second motor is fixedly connected to the second gear, the inner wall texture of the first gear matches the lead screw second, and the bottom of the output end of the fourth motor is fixedly connected to the threaded cylinder.

[0008] As a further technical solution of this utility model, the first gear is symmetrically meshed on both sides of the gear disk, and the second gear is meshed and connected to the left side of the first gear.

[0009] As a further technical solution of this utility model, hangers are fixed on both sides of the bottom of the support plate, and a screw rod is movably connected between the two hangers. Threaded sleeves are threadedly connected to both sides of the screw rod. A baffle is horizontally fixed at the bottom of the threaded sleeve, and screw holes are provided on both sides in front of the baffle. A bolt is threadedly connected to the front end of the hanger. A motor is fixed between the screw rod and the left hanger. A slot is longitudinally provided inside the baffle.

[0010] As a further technical solution of this utility model, the threaded sleeve is symmetrically sleeved on both sides of the outside of the lead screw three, and the inner wall texture of the threaded sleeve matches the lead screw three.

[0011] As a further technical solution of this utility model, the bolt is embedded in the screw hole of the baffle, and the baffle moves synchronously with the threaded sleeve.

[0012] As a further technical solution of this utility model, a frame is fixed between the left and right sides of the front end of the support plate, and a lead screw is movably connected between the left and right sides inside the frame. A threaded block is threaded to the outside of the lead screw, and an air jet rod is fixed to the bottom of the threaded block. An air pump is fixed to the right side of the top of the support plate, and a hose is fixed between the left side of the output end of the air pump and the threaded block. A motor is installed on the right side of the outside of the frame.

[0013] As a further technical solution of this utility model, the left side of the output end of the motor is fixedly connected to the lead screw, and the bottom of the hose passes through the threaded block and is connected to the jet rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the oil exploration surface rock breaking rotary drilling device not only achieves the verticality of the drilling tool and protects the drill bit, but also achieves the cleaning of soil on the surface of the mechanism;

[0015] (1) A drill bit is movably connected to the bottom of the threaded cylinder. The support plate at the bottom of the device is fixed to the drilling location by ground anchor. The motor 2 on the left side inside the support plate is started. The gear 1 on the left side is rotated by gear 2. The power is then transmitted to gear 1 on the right side through the gear plate.

Motor 4 is installed on the top of the assembly plate. Under the restriction of the inner wall of the thread at the bottom of the slot, the drill bit can be rotated out and into the threaded cylinder to perform drilling work, maintaining the temperature during device operation.

[0016] (2) By fixing a baffle at the bottom of the threaded sleeve laterally, after the drilling work is finished, the support plate and other objects are raised to increase the distance between the support plate and the base. The motor is started and the screw is rotated. The threaded sleeves on both sides of the screw are guided to converge or separate between the hangers on both sides. The slotted baffle is guided to move horizontally until the symmetrical baffles are joined together and cover the bottom of the drill bit for protection, without affecting the normal operation of the screw and other objects.

[0017] (3) By fixing an air rod at the bottom of the threaded block, after the various lifting and drilling mechanisms stop working, the motor can be started and the screw installed inside the frame can be rotated to guide the threaded block to move left and right along the inner wall of the frame along the screw. Adjust the left and right position of the air rod at the bottom of the threaded block so that the air pump can deliver gas to the air rod through the hose, clean the soil on the surface of each mechanism, and prevent the structure from jamming during operation.

[0033] Working Principle: In use, the support plate 1 at the bottom of the device is first fixed to the drilling location with a ground anchor. The motor 19 on the left side inside the support plate 1 is started, and gear 18 rotates the left gear 17. Power is then transmitted to the right gear 17 via the gear disc 16. The screw 6, which moves vertically along the inner walls of both gears 17, adjusts the distance between the support plate 1 and the base 5 until the bottom of the threaded cylinder 29 is embedded above the slot 7. A motor 30 is then installed on the top of the mounting plate 15. Under the constraint of the threaded inner wall at the bottom of the slot 7, the drill bit 8 can rotate in and out of the threaded cylinder 29 for drilling. After drilling is completed, the support plate 1 is raised to expand the support plate area. 1. The distance between the base 5 and the motor 22 is started and the screw 23 is rotated. The threaded sleeves 24 on both sides of the screw 23 are guided to converge or separate between the hangers 21 on both sides. The baffle 4 with the slot 26 is guided to move horizontally until the symmetrical baffles 4 are brought together and cover the bottom of the drill bit 8 for protection. After the lifting and drilling mechanisms stop working, the motor 11 is started and the screw 3 installed inside the frame 2 is rotated. The threaded block 10 is guided to move horizontally along the inner wall of the frame 2 along the screw 3. The left and right positions of the air jet rod 9 at the bottom of the threaded block 10 are adjusted so that the air pump 12 can deliver gas to the air jet rod 9 through the hose 13 and clean the soil on the surface of each mechanism.
