[0011] In one embodiment, the drilling equipment and working method for collecting soil for geothermal exploration include the following steps:
[0012] S1. Press the entire device and insert the drill bit into the soil for preliminary fixation. After the support rod touches the ground, step on the pressure plate with both feet to fix it.
[0013] S2. The motor drives the guide cylinder and the slide rod on the two surfaces of the pulley to rotate through the pulley assembly, and then drives the collection cylinder and the drill bit to rotate. The threaded cylinder and the collection cylinder are connected by bearings without conflict. The wheel is rotated manually, and the bevel gears rotate and engage to drive the screw and the threaded cylinder to work. The threaded cylinder pushes down the collection cylinder and the drill bit to move, allowing the device to drill deeper.

[0024] See also Figure 1-4The present invention provides a technical solution: a drilling device and working method for collecting soil for geothermal exploration, comprising a chassis 1, a fixed seat 10 is fixedly connected to one side of the chassis 1, a rotating rod 7 is rotatably connected to one side of the chassis 1, a rotating wheel 5 is fixedly connected to one end of the rotating rod 7, a bevel gear 8 is fixedly connected to one side of the rotating rod 7, a fixed platform 11 is fixedly connected to one side of the fixed seat 10, a screw 17 is rotatably connected to the inside of the fixed seat 10, the surface of the screw 17 is rotatably connected to the inside of the fixed platform 11, a bevel gear 2 9 is fixedly connected to the surface of one side of the screw 17, the bevel gear 18 is meshed with the bevel gear 29, a pulley 2 16 is rotatably connected to the surface of the fixed platform 11, a motor 12 is fixedly connected to one side of the chassis 1, a rotating rod 2 13 is arranged on one side of the motor 12, and the surface of the rotating rod 2 13 is fixed A pulley 14 is connected, and a belt 15 is provided on the surface of the pulley 14 and the pulley 2 16. A pair of fixed rods 20 are fixedly connected to one side of the fixed platform 11, and a fixed cylinder 21 is fixedly connected between the fixed rods 20. A threaded cylinder 18 is threadedly connected to the surface of the screw 17, and a guide plate 19 is fixedly connected to the surface of the threaded cylinder 18. The guide plate 19 is slidably connected to the inside of the fixed cylinder 21. A pair of guide cylinders 23 are fixedly connected to one side of the pulley 2 16, and a sliding rod 24 is slidably connected to the inside of the pair of guide cylinders 23. A fixed block 25 is fixedly connected to one end of the sliding rod 24, and a collecting cylinder 27 is fixedly connected to one side of the fixed block 25. A bearing 22 is provided between the collecting cylinder 27 and the threaded cylinder 18 for bearing connection. A collecting assembly is provided on one side of the collecting cylinder 27, and support assemblies are provided on both sides of the chassis 1.
[0025] Specifically, after the device is placed in a suitable position, the motor 12 is started, and the motor 12 drives the rotating rod 13 set on one side to rotate, and the pulley 14 fixed on the surface of the rotating rod 13 follows the rotation, and drives the pulley 16 to rotate on the surface of the fixed platform 11 through the belt 15 set on its surface. A pair of guide cylinders 23 are fixedly connected to the surface of the pulley 16 on one side, and a sliding rod 24 is slidably connected inside the guide cylinder 23. The sliding rod 24 is fixed to the collecting cylinder 27 through a fixed block 25. Since one side of the collecting cylinder 27 is connected to the threaded cylinder 18 through a bearing 22, and the thread has a self-locking property, the collecting cylinder 27 and the collecting assembly on one side will not slide or linearly move without rotating the rotating wheel 5, and will only be driven by the guide cylinder 23 and the sliding rod 24 to follow the rotation of the pulley 16. If the collecting assembly needs to be moved deeper underground, the rotating wheel 5 needs to be rotated. The rotation of the rotating wheel 5 drives the rotating rod 7 fixed on one side to rotate inside the chassis 1, and the bevel gear 8 fixed at one end of the rotating rod 7 is engaged with the gear 24 through the meshing The screw 17 is connected to the fixed seat 10 internally for rotation, so the screw 17 keeps rotating in the original position. The threaded cylinder 18 threadedly connected to the surface of the screw 17 is connected to the two guide plates 19 fixed on the surface. The guide plates 19 are connected to the internal sliding connection of the fixed cylinder 21. The fixed cylinder 21 is fixedly connected to the surface of the fixed platform 11 through the fixed rod 20. The threaded cylinder 18 is displaced in the direction of the collecting cylinder 27. Since the threaded cylinder 18 and the collecting cylinder 27 are connected by the bearing 22, the displacement of the threaded cylinder 18 is not affected when the collecting cylinder 27 rotates. The sliding rod 24 is connected to the internal sliding connection of the guide cylinder 23. The threaded cylinder 18 is displaced with the sliding rod 24, so that the collecting cylinder 27 is ejected, and the soil can be drilled and collected more deeply. This device structure can ensure that the motor 12 rotates in the original position, and the collecting assembly can be extended and displaced through the screw 17, so as to avoid the motor 12 going deep into the ground and the bad underground environment affecting the normal operation of the motor 12 for a long time.
[0026] The collecting assembly includes a cover plate 28 which is detachably mounted on one side of a collecting tube 27 . A locking screw 26 is threadedly connected to the inside of the collecting tube 27 and is used to fix the cover plate 28 . A drill bit 29 is provided at one end of the collecting tube 27 .
[0027] Specifically, the cover plate 28 in the collecting assembly is removable and fixed by a locking screw 26. Since there is a gap between the cover plate 28 and the outer surface of the collecting tube 27, and the cover plate 28 is more offset towards the outer surface of the collecting tube 27, as the rotation goes deeper, soil will enter from the gap between the cover plate 28 and the collecting tube 27 and slowly fill it up. The drill bit 29 makes it easier for the collecting tube 27 to go deeper into the ground, and the drilling and collection efficiency is higher.
[0028] The support assembly includes a support rod 3 , which is symmetrical and fixedly connected to a surface of the chassis 1 , and a pressure plate 4 is fixedly connected to one side of the support rod 3 .
[0029] Specifically, the support rod 3 is used to support the entire chassis device, and the pressure plate 4 can be stepped on by a worker or pressed down by other objects to better maintain stability.
[0030] A pair of support rods 6 are fixedly connected inside the chassis 1 , and one end of the support rod 6 is fixedly connected to the surface of the fixing seat 10 , wherein the gap between the support rod 6 and the chassis 1 is triangular.
[0031] Specifically, the support rod 6 is used to ensure the stability of the internal structure of the chassis 1, and the triangle has stability, making it not easy to deform, thereby increasing the service life.
[0032] A handle 2 is fixedly connected to one side surface of the chassis 1 .
[0033] Specifically, the handle 2 is convenient for the staff to transport the device, and if the rotating wheel 5 is rotated manually, it is also easier to exert force, thereby increasing work efficiency.
