Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-7The present invention provides a technical solution: a portable geological exploration drilling device, including a shell 1, and a spiral drill rod 2 that can rotate and rise simultaneously inside the shell 1; A support plate 3 is rotatably mounted on the outer wall of the outer shell 1 via a bearing seat. A movable plate 5 is rotatably mounted on one side of the support plate 3 via a bearing seat. The support plate 3 and the movable plate 5 are equidistant from the central axis of the outer shell 1. A first movable ring 4 is rotatably mounted on the lower end of the movable plate 5 via a bearing seat. The first movable ring 4 is movably nested on the outside of the outer shell 1. The outer casing 1 is provided with a fixing mechanism for storing and unfolding the support plate 3; The bottom of the support plate 3 is provided with a base plate 12 that can adapt to ground of different heights.

[0021] The fixing mechanism in this example includes a first movable ring 4. A locking rod 6 is threaded through one side of the first movable ring 4. One end of the locking rod 6 engages with the inside of a first slot 7. The first slot 7 is located on the outside of the outer casing 1. A second slot 8 is located on the outside of the outer casing 1 below the first slot 7. The first slot 7 and the second slot 8 have the same structure and are equal in size. Figure 1 As shown, when the locking rod 6 engages with the first slot 7, it allows several support plates 3 to unfold and be fixed in place, increasing the floor space at the bottom of the equipment and improving its stability. Figure 2-4 As shown, when the locking rod 6 engages with the second slot 8, several support plates 3 can be stored and fixed in place, reducing the footprint of the equipment and facilitating its transportation and carrying.

[0022] In this example, the outer wall of the outer casing 1 is fixed with a first positioning post 9. The bottom of the first positioning post 9 and the top of the first movable ring 4 are mutually bottomed. The outer wall of the outer casing 1 is fixed with a second positioning post 10 below the second slot 8. This ensures that when the first positioning post 9 contacts the first movable ring 4, the locking rod 6 and the first slot 7 can be aligned, which facilitates the locking rod 6 and the first slot 7 to engage. Similarly, when the first movable ring 4 contacts the second positioning post 10, the locking rod 6 and the second slot 8 can be aligned, which facilitates the locking rod 6 and the second slot 8 to engage.

[0023] In this example, a screw 11 is threaded through the bottom of the support plate 3. A base plate 12 is rotatably mounted on the outer side of the lower end of the screw 11 via a bearing. Mounting holes are provided on both sides of the base plate 12, allowing the fixing bolts to fix the base plate 12 to the ground through the mounting holes. Guide rods 13 are fixed on both sides of the top of the base plate 12. The guide rods 13 are slidably connected to the support plate 3. By rotating the screw 11, the height of the base plate 12 can be adjusted, thereby adjusting the height of the base plate 12 according to the height of the ground.

[0024] In this example, the screw 11 is nested with a first elastic rubber sleeve 14 and a second elastic rubber sleeve 16 on its outer side. A second movable ring 15 is rotatably mounted on the top of the outer side of the screw 11 via a bearing. The bottom of the second movable ring 15 is fixedly connected to the top of the second elastic rubber sleeve 16. The bottom of the second elastic rubber sleeve 16 is fixedly connected to the upper bottom surface of the support plate 3. The top of the base plate 12 is fixedly connected to the bottom of the first elastic rubber sleeve 14. The top of the first elastic rubber sleeve 14 is fixedly connected to the lower bottom surface of the support plate 3. A thread is provided on the outer side of the screw 11 between the top of the base plate 12 and the bottom of the second movable ring 15. The design of the first elastic rubber sleeve 14 and the second elastic rubber sleeve 16 protects the thread on the screw 11, preventing dust from entering the screw 11 and extending the service life of the screw 11.

[0025] In this example, an electric telescopic rod 17 is fixed to the inner top of the outer casing 1, a movable circular plate 18 is fixed to the lower end of the electric telescopic rod 17, a motor 19 is fixed to the bottom of the movable circular plate 18, and the bottom output end of the motor 19 is fixedly connected to the upper end of the spiral drill rod 2 by bolts. By starting the electric telescopic rod 17 and the motor 19, the spiral drill rod 2 can be driven to rise, fall and rotate.

[0026] In this example, a fixed plate is fixed to the inner bottom of the outer shell 1, and a limit rod 22 is fixed to the top of the fixed plate. The upper end of the limit rod 22 is fixedly connected to the inner top of the outer shell 1. The limit rod 22 is slidably connected to the movable circular plate 18. The limit rod 22 is symmetrically distributed about the central axis of the movable circular plate 18. The setting of the limit rod 22 increases the stability of the movement of the movable circular plate 18.

[0027] In this example, the bottom of the movable circular plate 18 is fixed with a U-shaped frame 20. The middle part of the U-shaped frame 20 is rotatably connected to the spiral drill rod 2 through a bearing. The U-shaped frame 20 increases the stability of the rotation of the spiral drill rod 2.

[0028] In this example, the outer wall of the outer casing 1 is equipped with a push-button switch 21. The push-button switch 21 is electrically connected to the electric telescopic rod 17 and the motor 19. The push-button switch 21 is connected to a power supply line, and the end of the power supply line is equipped with a plug. The bottom of the outer casing 1 is equipped with a scraper. The bottom of the scraper abuts against the inner side of the spiral drill rod 2. The scraper can scrape off the sample brought up from the geology by the spiral drill rod 2 without manual removal, thus improving work efficiency.

[0029] Working principle: When using this portable geological exploration drilling equipment, firstly as follows... Figure 2-4 As shown, firstly, the locking rod 6 is rotated. Since the locking rod 6 and the first movable ring 4 are threadedly connected, the locking rod 6 separates from the second slot 8, causing the first movable ring 4 to disengage. Then, the first movable ring 4 is pushed upwards. The first movable ring 4 pushes several support plates 3 to rotate simultaneously through several movable plates 5, causing... Figure 2 The state of the middle support plate 3 becomes Figure 1 When the top of the first movable ring 4 abuts against the bottom of the first positioning post 9, rotate the locking rod 6 so that the end of the locking rod 6 engages with the first slot 7, thus completing the fixation of the several support plates 3 after they are unfolded. Next, rotate screw 11. Since screw 11 and support plate 3 are threadedly connected, and base plate 12 is rotatably mounted on the outer side of the lower end of screw 11 through bearing, screw 11 pushes base plate 12 and guide rod 13 downward until the bottom of base plate 12 contacts the ground. Similarly, the other base plates 12 are brought into contact with the ground. Then, use fixing bolts to pass through the mounting holes on base plate 12 and insert them into the soil to fix base plate 12. Connect the power cord and plug on the push-button switch 21 to a power source. Activate the electric telescopic rod 17 and motor 19 via the push-button switch 21, causing the spiral drill rod 2 to rotate and move downwards, completing the drilling operation. Figure 7 As shown, activating the electric telescopic rod 17 causes the spiral drill rod 2 to move upward, and the sample on the spiral drill rod 2 is scraped off by the scraper. Similarly, pulling down to the first active ring 4 can make... Figure 1 The state of the middle support plate 3 becomes Figure 2 The state of the middle support plate 3 reduces the footprint of the equipment, making it easier to carry.
