DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 9 As shown, an embodiment of the present invention provides a hydrogeological drilling equipment, including a splash block 1, a plurality of support plates 2 are fixedly connected to the bottom of the splash block 1, and a plurality of support plates 2 are slidably connected to legs 3 in the middle of each of the support plates 2, a slide rail 4 is fixedly connected to one side of the top of the splash block 1, a linear motor 5 is slidably connected to the outer side of the slide rail 4, a first drive motor 6 is fixedly connected to the inside of the linear motor 5, a first connecting rod 7 is fixedly connected to the output end of the first drive motor 6, a connecting ring 8 is fixedly connected to one end of the first connecting rod 7, a first threaded sleeve 9 is fixedly connected to the inside of the first threaded sleeve 9, a sampling tube 10 is threadedly connected to the inside of the sampling tube 10, a drill bit 11 is provided at the bottom of the sampling tube 10, and a first threaded sleeve 9 is provided at the bottom of the sampling tube 10. A buffer component is provided inside the sample tube 10, and a pushing component is provided inside the sample tube 10. The linear motor 5 drives the first drive motor 6 to move, and the movement of the first drive motor 6 drives the first connecting rod 7 to move, and the movement of the first connecting rod 7 drives the first threaded sleeve 9 and the sample tube 10 to move, and the movement of the sample tube 10 drives the drill bit 11 to move. When the sample tube 10 moves downward, the conical surface at the bottom thereof contacts the soil and it is easier to drill into the soil. Since the sample tube 10 and the drill bit 11 enter the soil together, the hole wall can be effectively supported during drilling to avoid the collapse and deformation of the hole wall during drilling, and to avoid affecting the drilling quality and accuracy. At the same time, it can also effectively avoid accidents such as the falling off, breaking, and stuck drill of the drill tool. The buffer assembly includes a fixing ring 12, which is fixedly connected to the inside of the sampling tube 10, a cross ring 14 is fixedly connected to the inside of the fixing ring 12, a second connecting rod 13 is slidably connected to the middle of the cross ring 14, and two limit plates 15 are fixedly connected to the outside of the second connecting rod 13, a plurality of mounting grooves 16 are opened inside the cross ring 14, every two mounting grooves 16 form a group, and multiple groups of mounting grooves 16 are symmetrically arranged, one end of a spring 17 is fixedly connected to the inside of the multiple mounting grooves 16, and the other end of the multiple springs 17 is fixedly connected to a buffer plate 18, the drill bit 11 is fixedly connected to the bottom of the second connecting rod 13, and the two limit plates 15 are in contact with each group of buffer plates 18, through the first The driving motor 6 is started to drive the first connecting rod 7 to rotate, and the rotation of the first connecting rod 7 drives the connecting ring 8, the first threaded sleeve 9 and the sampling tube 10 to rotate. The rotation of the sampling tube 10 drives the fixing ring 12 to rotate, and the rotation of the fixing ring 12 drives the drill bit 11 to rotate, thereby performing drilling work. During drilling, when the drill bit 11 is drilling a hole in the ground, the drill bit 11 will have high-frequency contact with the soil and stones, and high-frequency vibration will be generated. At this time, the vibration drives the drill bit 11 to move up and down at a high frequency, thereby driving the limit plate 15 to move. When the limit plate 15 moves, the spring 17 will be compressed. When compressed, the spring 17 will absorb part of the potential energy to reduce the impact on the drill bit 11, thereby effectively avoiding damage to the drill bit 11 caused by high-frequency vibration, thereby improving the service life.

[0019] Wherein, the pushing assembly includes a second driving motor 19, which is rotatably connected to the inside of the first connecting rod 7, and the output end of the second driving motor 19 is fixedly connected to the first threaded shaft 20, and the outer side of the first threaded shaft 20 is threadedly connected to the second threaded sleeve 21, and the inner side of the second threaded sleeve 21 is provided with a threaded base 22, and the outer side of the first threaded shaft 20 is threadedly connected to the third threaded sleeve 24, and the third threaded sleeve 24 is fixedly engaged with the second threaded sleeve 21, and one end of the third threaded sleeve 24 is fixedly connected to an extrusion plate 25, and the outer side of the extrusion plate 25 is fixedly connected to two limit blocks 26, and the pushing assembly also includes a water outlet 27, and a push plate 28 is slidably connected to one side of the sampling tube 10, and the water outlet 27 is opened on the outer surface of the sampling tube 10 and communicated with the inner cavity of the sampling tube 10, and the diameter of the water outlet 27 is 1mm, and the water outlet 27 is located above the push plate 28, and two limit grooves 29 are opened inside the sampling tube 10, and the two limit blocks 26 are slidably connected in the limit grooves 29. The length and width of the limit block 26 and the limit groove 29 are equal. By starting the second drive motor 19, the rotation of the second drive motor 19 will drive the first threaded shaft 20 to rotate. The rotation of the first threaded shaft 20 pushes the second threaded sleeve 21 and the third threaded sleeve 24 out. The movement of the third threaded sleeve 24 drives the extrusion plate 25 to move. The movement of the extrusion plate 25 reinforces the soft soil, so that the soil gradually becomes more solid under the action of pressure, thereby improving its bearing capacity and stability, facilitating subsequent soil testing, avoiding subsequent additional processing, increasing engineering costs, and reducing work efficiency. At the same time, it can avoid that the soil suddenly enters the cavity of the shaft during movement to form a blockage, thereby affecting work efficiency. If the extrusion plate 25 squeezes the soft soil and the soil is still not convenient for testing, the push plate 28 can be opened and the circular plate can be placed, and then mechanical compaction can be performed again, so that the molding effect is better through the support of the circular plate, and its bearing capacity and stability are further improved. Since the soft soil contains more water inside, the water can flow out through the water outlet 27 after squeezing.

[0020] Among them, the bottom of the inner wall of the sampling tube 10 is provided with an inner chamfer and is designed to be symmetrical on the left and right. The inclined edge is connected to the inner diameter of the sampling tube 10, so that soft soil can be better sampled inside the sampling tube 10 along the inclined edge. Secondly, it can effectively reduce the obstacles to entering the soil layer, reduce the drilling pressure, and improve the drilling effect.

[0021] Among them, the structure of the connection between the threaded base 22 and the first threaded shaft 20 is a convex ring, and the first threaded shaft 20 is a concave ring. The threaded base 22 and the first threaded shaft 20 are rotatably connected through the convex ring and the concave ring. The structure of the connection between the threaded base 22 and the first threaded shaft 20 is a convex ring, and the first threaded shaft 20 is a concave ring, so that the first threaded shaft 20 can effectively push the threaded base 22 to move without hindering its movement.

[0022] Working principle: When hydrogeological drilling is required, the linear motor 5 is started, and the linear motor 5 drives the first drive motor 6 to move, and the movement of the first drive motor 6 drives the first connecting rod 7 to move, and the movement of the first connecting rod 7 drives the first threaded sleeve 9 and the sampling tube 10 to move, and the movement of the sampling tube 10 drives the drill bit 11 to move. When the sampling tube 10 moves downward, the conical surface at the bottom thereof contacts the soil and it is easier to drill into the soil. Moreover, since the sampling tube 10 and the drill bit 11 enter the soil together, the hole wall can be effectively supported during drilling to avoid collapse and deformation of the hole wall during drilling, and to avoid affecting the drilling quality and accuracy. At the same time, it can also effectively avoid accidents such as the drilling tool falling off, breaking, and drill jamming. At this time, the first drive motor 6 is started, and the first drive motor 6 is started. The first connecting rod 7 is driven to rotate, and the rotation of the first connecting rod 7 drives the connecting ring 8, the first threaded sleeve 9 and the sampling tube 10 to rotate. The rotation of the sampling tube 10 drives the fixing ring 12 to rotate, and the rotation of the fixing ring 12 drives the drill bit 11 to rotate, so as to perform drilling work. During drilling, when the drill bit 11 is drilling a hole in the ground, the drill bit 11 will have high-frequency contact with soil and stones, and high-frequency vibration will be generated. At this time, the vibration drives the drill bit 11 to move up and down at high frequency, and then drives the limit plate 15 to move. When the limit plate 15 moves, the spring 17 will be compressed. When the spring 17 is compressed, it will absorb part of the potential energy to reduce the impact on the drill bit 11, so as to effectively avoid the damage of the drill bit 11 caused by high-frequency vibration, thereby improving the service life; At the same time, when the drill bit 11 moves downward and the drilling is completed, when it is necessary to analyze the soil layer, due to the characteristics of soft soil, it is not easy to form during sampling. At this time, the second drive motor 19 is started, and the rotation of the second drive motor 19 will drive the first threaded shaft 20 to rotate. The rotation of the first threaded shaft 20 pushes the second threaded sleeve 21 and the third threaded sleeve 24 out. The movement of the third threaded sleeve 24 drives the extrusion plate 25 to move. The movement of the extrusion plate 25 reinforces the soft soil, so that the soil gradually becomes more solid under pressure, thereby improving its bearing capacity and stability, facilitating subsequent soil testing, avoiding subsequent additional processing, and at the same time preventing the soil from suddenly entering the cavity of the shaft during movement to form a blockage, thereby affecting work efficiency.
