[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a portable rock and soil exploration drilling device, comprising: a support base 1 with two movable wheels 2 installed at its end; a movable sliding cover 4 slidably installed on the top of the support base 1, with a storage rack installed on the top of the movable sliding cover 4 for storing drill rods and fixing counterweights; a lifting column 9 fixedly connected to the top of the support base 1, with a sliding sleeve 13 slidably connected to the outside of the lifting column 9, a chain 10 installed inside the lifting column 9 to drive the sliding sleeve 13 to rotate, and a gasoline engine 14 fixedly connected to one side of the sliding sleeve 13 for driving the drill rods and adjusting the center of gravity of the lifting column 9 after tilting.

[0024] It should be noted that in this embodiment, the support base 1 is placed in a horizontal state, and the movable sliding cover 4 is slid to one end. The support base 1 is then supported and fixed by the storage rack on top of the movable sliding cover 4, causing the gasoline engine 14 and the movable sliding cover 4 to be vertically misaligned. The drill rod is fixed to the output end of the gasoline engine 14, and the water pipe is connected to the water pipe connector at the top of the drill rod. The gasoline engine 14 drives the drill rod to rotate, and the drive chain 10 drives the sliding sleeve 13 to rise and fall outside the lifting column 9. The sliding sleeve 13 then drives the gasoline engine 14 to move downwards, thus drilling the ground through the drill rod. The drill rod enters the bottom... During drilling, the remaining drill rods are spliced ​​and extended before being connected to the gasoline engine 14 to extend the drilling depth. After drilling is completed, the drill rods are lifted from the ground and removed in sections. The internal samples are then removed and placed in the storage rack. The sliding cover 4 is slid to the bottom of the gasoline engine 14. Using the lifting column 9 as the lever arm and the moving wheel 2 as the fulcrum, the support base 1 is tilted up. The position of the gasoline engine 14 is adjusted as needed so that when the moving wheel 2 is used as the fulcrum, the position of the gasoline engine 14 balances the weight of the storage rack, making it convenient to drag the entire device through the handwheel 11 at the end of the lifting column 9.

[0025] In one embodiment, the support base 1 has limit grooves 3 on both sides, and the inner side of the movable sliding cover 4 is fixedly connected to a limit block that is slidably connected to the limit groove 3. Both ends of the inner side of the movable sliding cover 4 are rotatably connected to limit rollers 5. A limit plate 6 is fixedly connected to one side of the support base 1 and slidably connected to the side of the movable sliding cover 4. A limit groove 7 is opened in the middle of the limit plate 6. A metal rod is slidably connected inside the limit groove 7. The metal rod is fixedly connected to the outer side of the movable sliding cover 4. A limit hook plate 8 that cooperates with the metal rod is rotatably connected to the outer side of the limit plate 6.

[0026] It should be noted that in this embodiment, one of the limiting rollers 5 is rolled inside the limiting groove 3, and the bottom of the other limiting roller 5 at the end of the movable sliding cover 4 is flush with the bottom of the support base 1. When the movable sliding cover 4 is slid to the bottom of the gasoline engine 14, the limiting hook plate 8 rotates, so that one end of the limiting hook plate 8 is locked on the outside of the metal rod outside the movable sliding cover 4, thereby limiting the position of the movable sliding cover 4. The end of the metal rod is threaded with a nut. When the limiting hook plate 8 is engaged with the metal rod, the nut can be used to press the limiting hook plate 8 to achieve fixation. When the movable sliding cover 4 is slid to one end of the limiting groove 7, the nut and the limiting plate 6 can press and fix the movable sliding cover 4 in the designated position.

[0027] In one embodiment, the storage rack includes a support frame 15 fixed to the top of the movable sliding cover 4, with limit baffles 16 fixed to each of the four corners of the support frame 15, and a top cover 17 slidably connected to the limit baffles 16 on the top of the support frame 15.

[0028] It should be noted that in this embodiment, the top cover 17 can slide upward and separate from the top cover 17, thereby removing the drill rods at the top of the support frame 15. When fixing, the limiting baffle 16 is passed out from the corresponding hole of the top cover 17. The side of the top cover 17 is threaded with bolts corresponding to the position of the limiting baffle 16. The top cover 17 can be positioned at a specified height by pressing the limiting baffle 16 with the bolts, thereby pressing and constraining the drill rods arranged at the top of the support frame 15.

[0029] In one embodiment, the lifting column 9 has two sprockets rotatably connected inside, and the two sprockets are connected by a chain 10. A metal block is rotatably connected to the outside of the sliding sleeve 13, and the metal block is fixed to the sliding sleeve 13. A reducer 18 is fixedly connected to one side of the top of the lifting column 9. The output end of the reducer 18 is connected to the sprocket located above. A handwheel 11 is fixedly connected to the input end of the reducer 18. A vertical groove is opened on one side of the lifting column 9, which is slidably connected to the metal block. Brushes 12 are fixedly connected to both sides of the vertical groove.

[0030] It should be noted that in this embodiment, the reducer 18 is a worm gear reducer. The handwheel 11 drives the worm gear through the worm, and the worm gear drives the chain located above to rotate, thereby driving the sliding sleeve 13 to move through the chain. The sliding sleeve 13 drives the gasoline engine 14 to move up and down. During the up and down movement of the sliding sleeve 13, it slides against the brush 12. The brush 12 can block the vertical groove, reducing the probability of soil entering the lifting column 9 and protecting the chain.
