Description

Technical Field

[0001] The invention relates to the field of geological survey sampling, in particular to a geological survey sampler with an angle adjustment bracket. Background Art

[0002] "Geological exploration" refers to the investigation and research activities that use various means and methods to survey and detect geology, determine the appropriate bearing layer, determine the foundation type according to the bearing capacity of the bearing layer, and calculate the foundation parameters. When conducting geological surveys in a certain area, it is necessary to take deep core samples, and the sampling methods are drilling sampling and manual drilling sampling. In some special spaces, it is inconvenient for large equipment to enter, and soil sampling can only be done manually with samplers. Common handheld samplers use motors to drive the drill bit into the ground and take samples through sampling tubes.

[0003] Most of the existing samplers are bare and are usually not used in conjunction with a fixed bracket. It is necessary to turn on the motor and manually press the handle ends on both sides to insert the borehole into the ground. This process will have the following problems. On the one hand, when the borehole is inserted into the ground, it is not guided by any means. Therefore, the verticality of the borehole depends entirely on the operator's rough judgment, which results in large errors and affects the results of soil sampling. On the other hand, without any protection, the transmission of the motor and the drill bit will produce violent vibrations, which will cause the land around the borehole to crack and damage the surrounding environment. Thirdly, due to the lack of fixing measures, when encountering inclined ground, it will affect the verticality of the borehole and make drilling more difficult. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a geological survey sampler with an angle adjustment bracket to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. The support component maintains the stability of the sampler body during drilling and cooperates with the pad to reduce the possibility of cracking of the surrounding land, as well as guide the direction of the drilling. Under the action of the fixing component, it is fixed on the ground, and the stability of the device during use is further enhanced. It can also be adjusted according to the terrain to keep the drilled hole vertical under any inclined terrain. Under the action of the buffer component, the damage caused by the vibration of the drilling to the surrounding environment is reduced.

[0006] Furthermore, the support assembly includes a vertical rod, and the four corners of the top of the pad are rotatably connected to the vertical rods through a universal shaft. A limiting sleeve is installed on the outer side of the pulling handle corresponding to the movement path of the four vertical rods through a rotating shaft, and the vertical rod is slidably inserted in the limiting sleeve.

[0007] Furthermore, a baffle is fixed on the top of the vertical rod passing through the limiting sleeve, and a second spring is sleeved on the vertical rod between the baffle and the top of the limiting sleeve.

[0008] Furthermore, the fixing assembly includes a fixing sleeve, a fixing sleeve is fixed on the bottom surface of the vertical rod, and pins are installed on the outside of the fixing sleeve through a rotating shaft, a linkage shaft is installed between two pins on the top of the base plate that are perpendicular to one side of the two pulling handles, and foot pedals are provided on the other two sides of the top of the base plate, and the foot pedals are fixed on the fixing sleeve.

[0009] Furthermore, the pin includes a sliding frame, which is rotatably mounted on the outer surface of the fixed sleeve through a rotating shaft, and one side of the sliding frame is hollowed out, an L-shaped plate is slidably inserted inside the sliding frame, and a locking bolt is engaged and inserted on the surface of the L-shaped plate and the sliding frame.

[0010] Furthermore, the linkage shaft passes through the pin and the two ends of the fixed sleeve shaft and is sleeved with an engaging sleeve, and the outer surfaces of the pin and the fixed sleeve shaft are fixed with a threaded ring at a position corresponding to the outer ring of the linkage shaft, and the threaded ring can be engaged with the engaging sleeve.

[0011] Furthermore, the buffer assembly includes a first connecting rod, which is rotatably connected to the inner surface of the fixed sleeve via a rotating shaft, a guide cylinder is slidably connected to the surface of the drill bit and the fixed sleeve on the same horizontal line, and the guide cylinder is rotatably connected to the second connecting rod corresponding to the position of the first connecting rod, the other ends of the first connecting rod and the second connecting rod are rotatably connected to the same sliding sleeve, a sliding rod is slidably inserted inside the sliding sleeve, and the sliding rod is fixed on a pad, and a third spring is fixed between the top of the sliding rod and the sliding sleeve.

[0012] Furthermore, the outer sides of the two groups of pulling handles are rotatably connected to telescopic rods via rotating shafts, and the outer rings of the telescopic rods are fixedly sleeved with first springs.

[0013] Furthermore, a level is fixed at the top center of the driving device.

[0014] The beneficial effects of the present invention are as follows: a geological survey sampler with an angle adjustment bracket of the present invention comprises a sampler body; a driving device; a drill bit; a level; a lifting handle; a telescopic rod; a first spring; a supporting assembly; a sliding sleeve; a vertical rod; a baffle; a second spring; a pad; a fixing assembly; a pin; an L-shaped plate; a sliding frame; a locking bolt; a linkage shaft; a threaded ring; an engaging sleeve; a fixing sleeve; a guide cylinder; a foot pedal; a buffer assembly; a first connecting rod; a second connecting rod; a sliding rod; a sliding sleeve; and a third spring.

[0015] 1. This geological survey sampler with an angle adjustment bracket is covered on the ground around the borehole by the support assembly and the pad.

With two opposite forces, the upward traction force and the downward squeezing force in contact with the ground, it is more convenient to remove the sampler body.

[0018] 4. In this geological survey sampler with an angle adjustment bracket, under the action of the buffer component, when the drill bit vibrates during operation, the first connecting rod and the second connecting rod drive the sliding sleeve to slide along the surface of the sliding rod and compress or stretch the third spring to perform a buffering effect, thereby reducing the negative impact caused by the vibration of the drill bit.

[0019] 5. Compared with the existing technology, this geological survey sampler with an angle adjustment bracket can effectively improve the vertical accuracy of the drill bit drilling. Compared with rough manual estimation, it has higher accuracy and more precise soil sampling. By reducing the impact of the drill bit's shaking on the surrounding environment and the squeezing effect on the ground around the borehole, the cracking of the ground around the borehole is reduced, and the surrounding environment is protected. It is simpler and more labor-saving to pull out the device later without damaging the ground. It has strong adaptability to the ground in different environments, can be adjusted and fixed on the ground according to the ground conditions, and the stability of the bottom of the device is enhanced.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 6 The present invention provides a technical solution: a geological survey sampler with an angle adjustment bracket, comprising a sampler body 1, the sampler body 1 comprising a driving device 11 and a drill bit 12, and the driving device 11 and the drill bit 12 are transmission-mounted, the bottom of the driving device 11 is located on both sides of the drill bit 12 installation position and is rotatably mounted with two groups of lifting handles 3 through a rotating shaft, the outer sides of the two groups of the lifting handles 3 are provided with a supporting assembly 5 for supporting and guiding the sampler body 1, and a pad 6 is provided at the bottom of the supporting assembly 5, the pad 6 is provided with a through hole corresponding to the position of the drill bit 12, and the drill bit 12 contacts the ground through the through hole, the bottom of the supporting assembly 5 is provided with a fixing assembly 7 fixed to the ground on both sides, the surface of the pad 6 is provided with a buffer assembly 8 for reducing the jitter generated when the drill bit 12 is working, and the outer sides of the two groups of the lifting handles 3 are both through The telescopic rod 4 is connected to the rotating shaft, and the outer ring fixing sleeve 73 of the telescopic rod 4 is connected to the first spring 41. The telescopic rod 4 and the first spring 41 can place the two sets of lifting handles 3 to rotate in a normal state to limit them. When using the device, the pad 6 is placed on the perforated ground, and then the drill bit 12 of the sampler body 1 passes through the through hole of the pad 6. The bottom of the device is fixed along the terrain through the fixing component 7 to maintain the stability of the bottom of the device. The lifting handle 3 is pressed and the driving device 11 is turned on (the driving device 11 and the drill bit 12 of the sampler body 1 are the same as the existing portable earth drilling machine structure principle and sampling method) to drill a hole into the ground for soil sampling. During the process, the drilling path is kept in a vertical direction due to the guiding effect of the support component 5, and the buffer component 8 is used to reduce the negative impact of the vibration of the drill bit 12 on the surrounding ground.

[0029] In this embodiment, the support assembly 5 includes a vertical rod 52, and the four corners of the top of the pad 6 are rotatably connected to the vertical rod 52 through a universal shaft. The outer side of the lifting handle 3 corresponds to the movement path of the four vertical rods 52, which are rotatably installed with a limit sleeve 51 through a rotating shaft, and the vertical rod 52 is slidably inserted in the limit sleeve 51. The top of the vertical rod 52 passing through the limit sleeve 51 is fixed with a baffle 53, and the vertical rod 52 is located between the baffle 53 and the top of the limit sleeve 51 and is sleeved with a second spring 54. The pad 6 at the bottom of the vertical rod 52 is supported by a soft rubber material and can cover the drill. On the ground around the hole, the squeezing effect of the pad 6 can reduce the cracking of the ground around the drill hole due to drilling vibration, protect the surrounding environment, and after the pad 6 contacts the ground, the four vertical rods 52 form a support frame, which guides the sampler body 1 when it moves downward, and the drill bit 12 is inserted into the ground to drill a hole by pressing the lifting handle 3. The vertical rod 52 slides along the surface of the limit sleeve 51 to stretch the second spring 54, so as to keep the drilling path moving in the vertical direction. The second spring 54 plays an auxiliary role when the drill bit 12 is pulled out later.

[0030] In this embodiment, the fixing assembly 7 includes a fixing sleeve 73, the fixing sleeve 73 is fixed on the bottom surface of the vertical rod 52, and the outer side of the fixing sleeve 73 is rotatably mounted with a pin 71 through a rotating shaft, a linkage shaft 72 is installed between the two pins 71 on the top of the pad 6 perpendicular to one side of the two lifting handles 3, and pedals 75 are provided on the other two sides of the top of the pad 6, and the pedals 75 are fixed on the fixing sleeve 73, and the pin 71 includes a sliding frame 712, and the sliding frame 712 is rotatably mounted on the outer surface of the fixing sleeve 73 through a rotating shaft, and one side of the sliding frame 712 is hollow. The sliding frame 712 is slidably inserted with an L-shaped plate 711 inside, and a locking bolt 713 is meshed and inserted on the surface of the sliding connection between the L-shaped plate 711 and the sliding frame 712. The linkage shaft 72 passes through the pin 71 and the two ends of the fixed sleeve 73 are sleeved with an engagement sleeve 722. The outer surfaces of the pin 71 and the fixed sleeve 73 are fixed with a threaded ring 721 at a position corresponding to the outer ring of the linkage shaft 72, and the threaded ring 721 can be meshed and connected with the engagement sleeve 722. The engagement sleeve 722 can slide and rotate along the surface of the linkage shaft 72 while being connected and installed with the linkage shaft 72. When the angle of the pin 71 needs to be changed, the engagement sleeve 722 is rotated to disengage from the engagement with the threaded ring 721. At this time, the linkage shaft 72 is rotated, and the two pins 71 on the same side are rotated. After the angle is determined, the engagement sleeve 722 and the threaded ring 721 are engaged to lock the pin 71 so that it cannot rotate. The L-shaped plate 711 is moved along the sliding frame 712, and the length of the L-shaped plate 711 moved is selected according to the terrain, so that it is more convenient to plug and fix it on the ground. After confirming the length, the locking bolt 713 is used to squeeze the inner wall of the sliding frame 712 to achieve the L-shaped plate By locking 711, the entire fixing assembly 7 is adapted to different terrains (such as uneven ground or inclined ground) by adjusting the position and angle of contact between the cover pin 71 and the ground. The bottom of the retaining device can be fixed on the ground. When pulling the sampler body 1 out of the ground, it is necessary to step on the pedal 75, and keep the vertical rod 52 in contact with the ground through the fixing sleeve 73. Then, the lifting handle 3 is turned to pull the sampler body 1 upward. The two opposite forces (upward traction and downward squeezing force in contact with the ground) make it easier to remove the sampler body 1.

[0031] In this embodiment, the buffer assembly 8 includes a first connecting rod 81, and the first connecting rod 81 is rotatably connected to the inner surface of the fixed sleeve 73 through a rotating shaft. A guide cylinder 74 is slidably sleeved on the surface of the drill bit 12 on the same horizontal line as the fixed sleeve 73, and the guide cylinder 74 is rotatably connected to the second connecting rod 82 corresponding to the position of the first connecting rod 81. The other ends of the first connecting rod 81 and the second connecting rod 82 are both rotatably connected to the same sliding sleeve 84, and a sliding rod 83 is slidably inserted inside the sliding sleeve 84, and the sliding rod 83 is fixed on the pad 6. A third spring 85 is fixed between the top of the rod 83 and the sliding sleeve 84. The guide cylinder 74 maintains connectivity with the fixed sleeve 73 and the pad 6 through the first connecting rod 81, the second connecting rod 82 and the sliding rod 83. The sliding sleeve is connected to the outer wall of the drill bit 12 to limit and guide the movement path of the drill bit 12. When the drill bit 12 vibrates during operation, the first connecting rod 81 and the second connecting rod 82 drive the sliding sleeve 84 to slide along the surface of the sliding rod 83 and compress or stretch the third spring 85 for buffering, thereby reducing the negative impact caused by the shaking of the drill bit 12.

[0032] In this embodiment, a spirit level 2 is fixed at the top center of the driving device 11. The spirit level 2 has the same principle as the existing bubble calibrator and can detect the verticality of the installed device before drilling sampling to ensure that drilling sampling is performed in a vertical state.

[0033] When the locking nut 72 is in the state of being loosened, the locking nut 72 is engaged with the locking nut 711 and the locking nut 73 is engaged with the locking nut 712, thereby locking the locking nut 720 in the state of being loosened. The drill bit 12 is inserted into the ground to drill a hole by pressing the lifting handle 3. The vertical rod 52 slides along the surface of the limiting sleeve 51 to stretch the second spring 54, and the drilling path is kept moving in the vertical direction. The buffer assembly 8 is used to reduce the negative impact of the vibration of the drill bit 12 on the surrounding ground. When the drill bit 12 vibrates during operation, the first connecting rod 81 and the second connecting rod 82 drive the sliding sleeve 84 to slide along the surface of the sliding rod 83 and compress or stretch the third spring 85 for buffering, thereby reducing the negative impact caused by the vibration of the drill bit 12. When the sampler body 1 is pulled out of the ground, it is necessary to step on the foot pedal 75, keep the vertical rod 52 in contact with the ground through the fixing sleeve 73, and then turn the lifting handle 3 to pull the sampler body 1 upward, so that the removal of the sampler body 1 is more convenient with two forces in opposite directions.
