Detailed Implementation

[0038] 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.

[0039] Please see Figures 1-3The present invention provides the following technical solution: a drilling and sampling device for rock and soil exploration, including a sampling cylinder 1 and an auxiliary feeding mechanism 2, wherein the auxiliary feeding mechanism 2 includes: a rotating rod 21, a fixed plate 22, a spiral auger 23 and a handle 24.

[0040] Furthermore, by Figure 1 and Figure 2 As shown in this embodiment, the rotating rod 21 is rotatably connected to the sampling cylinder 1, and part of the rotating rod 21 is embedded in the sampling cylinder 1. The fixing plate 22 is fixed to the embedded end of the rotating rod 21, the spiral auger 23 is fixed on the fixing plate 22, and the handle 24 is fixed to the top of the rotating rod 21. With the above scheme, when using it, when sampling, the sampling cylinder 1 is made perpendicular to the ground, and then the sampling cylinder 1 is rotated so that the sampling cylinder 1 is inserted into the soil foundation. At this time, some soil will enter the inside of the sampling cylinder 1. The spiral structure of the spiral auger 23 can stably engage with the soil sample to prevent the soil sample from falling out accidentally. Then the sampling cylinder 1 is pulled out, and the spiral auger 23 is rotated using the handle 24. The spiral auger 23 can push out the soil sample in the sampling cylinder 1, which is convenient for unloading and helps to improve work efficiency.

[0041] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the outer wall of the spiral auger 23 abuts against the inner wall of the sampling cylinder 1. With the above solution, when in use, the spiral auger 23 can scrape off the soil and rock samples that are stuck to the inner wall of the sampling cylinder 1 when it rotates, ensuring that the soil and rock samples are fully discharged, eliminating the need for cleaning, and improving work efficiency.

[0042] Preferably, by Figure 1 As shown, this embodiment also includes a spiral blade 11, which is fixed to the outer wall of the sampling cylinder 1. With the above solution, when the sampling cylinder 1 is rotated during use, the spiral blade 11 rotates and the spiral blade 11 and the soil foundation generate a threaded engagement, which is beneficial for inserting the sampling cylinder 1 into the soil foundation.

[0043] Preferably, by Figure 1 As shown, in this embodiment, it also includes: cones 12, a plurality of cones 12 are fixed at equal intervals along the circumferential direction at the bottom end of the sampling tube 1. With the above scheme, when in use, the cones 12 have sharp points, which is conducive to inserting the sampling tube 1 into the soil foundation, and the cones 12 can break through the hardened soil foundation.

[0044] Preferably, by Figure 1 and Figure 3As shown, this embodiment also includes an operating mechanism 3, which is fixed to the sampling cylinder 1 and used to control the rotation of the sampling cylinder 1. The operating mechanism 3 includes: a fixed ring 31, an inner ratchet 32, locking pins 33, a return spring 34, a baffle 35, a C-shaped frame 36, and a handle 37. A fixed tube 311 is fixed to the fixed ring 31 and is fixedly connected to the sampling cylinder 1 with bolts. Multiple clearance grooves 312 are machined on the circumferential surface of the fixed ring 31 at equal intervals along the circumferential direction. The inner ratchet 32 ​​is sleeved on the fixed ring 31 and rotatably connected to the fixed ring 31. Multiple locking pins 33 are evenly distributed along the circumferential direction and mesh with the ratchet teeth of the inner ratchet 32. The return spring 34 is fixed to the inner wall of the clearance groove 312 and the locking pins 33. In this configuration, baffles 35 are fixed at both the top and bottom of the inner ratchet 32, and a C-shaped frame 36 is fixed on the baffles 35. The handle 37 is fixed to the outer wall of the C-shaped frame 36. With this configuration, when in use, the operator holds the two handles 37 with both hands. When the handles 37 are turned clockwise, the handles 37 drive the inner ratchet 32 ​​to rotate. Since the locking pin 33 meshes with the ratchet teeth of the inner ratchet 32, the inner ratchet 32 ​​can drive the fixing ring 31 to rotate, causing the sampling cylinder 1 to rotate. When the handles 37 are turned counterclockwise, the handles 37 drive the inner ratchet 32 ​​to rotate, and the inclined surface of the ratchet teeth will squeeze the locking pin 33 into the relief groove 312. The return spring 34 contracts, and at this time the fixing ring 31 cannot rotate, realizing the function of unidirectional rotation, making the operation more convenient.

[0045] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the outer wall of the sampling tube 1 abuts against the inner wall of the fixing tube 311. After adopting the above solution, the stability of the fixing ring 31 installation is further improved during use, and the fixing ring 31 is prevented from shaking or loosening.

[0046] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the baffle 35 is sleeved on the fixed tube 311, and the inner wall of the baffle 35 abuts against the outer wall of the fixed tube 311. With the above solution, during use, the two baffles 35 limit the inner ratchet 32 ​​from the upper and lower sides respectively, ensuring the stability of the inner ratchet 32 ​​and the fixed ring 31.

[0047] Preferably, by Figure 1 and Figure 3 As shown, this embodiment also includes a limiting ring 13, which is fixed on the sampling cylinder 1 and used to support the operating mechanism 3. With the above solution, the installation position of the operating mechanism 3 is positioned by the limiting ring 13 during use, and at the same time, it is used to support the operating mechanism 3, which further improves the stability of the operating mechanism 3.

[0048] Components not described in detail in this article are existing technologies.

[0049] The working principle and usage process of this utility model: When using the sampling device of this utility model, the sampling cylinder 1 is perpendicular to the ground. The operator holds the two handles 37 with both hands. When the handles 37 are rotated clockwise, the handles 37 drive the inner ratchet 32 ​​to rotate. Since the locking pin 33 is engaged with the ratchet teeth of the inner ratchet 32, the inner ratchet 32 ​​can drive the fixing ring 31 to rotate, causing the sampling cylinder 1 to rotate. When the handles 37 are rotated counterclockwise, the handles 37 drive the inner ratchet 32 ​​to rotate. The inclined surface of the ratchet teeth will squeeze the locking pin 33 into the relief groove 312, and the return spring 34 will retract. At this time, the fixing ring 31 cannot rotate, realizing the function of unidirectional rotation, making the operation more convenient. Under this structure, it is only necessary to rotate the handles 37 back and forth to make the sampling cylinder 1 always rotate in the same direction.

[0050] After the sampling tube 1 is inserted into the soil foundation, some soil will enter the inside of the sampling tube 1. The spiral structure of the auger 23 can stably engage with the soil sample to prevent the soil sample from falling out accidentally.

[0051] Then, pull out the sampling tube 1 and use the handle 24 to rotate the auger 23. The auger 23 can push out the soil and rock sample in the sampling tube 1, which is convenient for unloading and helps to improve work efficiency.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
