Detailed Description
The invention will be further described in detail with reference to the following examples, which are given in the accompanying drawings.
As shown with reference to figures 1-6,
a geological drilling sampling system comprises a drilling machine 1, a drill bit 2 arranged on the drilling machine 1, and a soil sample storage tank for filling soil; the drill bit 2 adopts a drill rod 4 with threads, and when the drill rod 4 drills into soil, the drill rod 4 sends out the soil upwards through the drill rod 4; the filling device 5 is arranged on the ground corresponding to the position of the hole; the side surface of the filling device 5 is provided with an opening 51 for the drill rod 4 to penetrate from the side surface; filling device 5 has the transmission path 52 that is used for transmitting soil sample storage jar 3, the position that corresponds transmission path 52 on filling device 5 still is provided with scraper blade 53, scraper blade 53 is used for cooperating the screw on drilling rod 4 surface to carry out soil and strikes off, soil sample storage jar 3 still is used for receiving scraper blade 53 and strikes off the soil that drops, transmission path 52 loops through soil sample storage jar 3 and sees off after receiving soil.
Because rig 1 can be simply be located ground, also can be located the hull of submarine drilling, cooperation drilling rod 4 drills, the side of current drill bit 2 has the screw thread, can take out soil in the drilling, this characteristic of cooperation, loading device 5 of this scheme can scrape the soil that carries on the screw thread of screw rod, and the soil that scrapes can enter into the soil sample storage jar 3 in transmission passage 52 through scraper blade 53 direction, the removal of cooperation soil sample storage jar 3 in transmission passage 52, can let scraper blade 53 fall into each soil sample storage jar 3 with the soil that scrapes in proper order. Wherein transmission channel 52 adopts the passageway that link up whole filling device 5, and soil sample storage jar 3 is put into to one end, just can extrude the soil sample storage jar 3 of opposite side, realizes that the pairing of soil sample storage jar 3 and scraper blade 53 switches, and then hangs soil and falls into different soil sample storage jar 3, is convenient for encapsulate soil, constitutes a plurality of different experimental groups. The side of the filling device 5 is provided with an opening 51, which can facilitate the installation of the filling device 5, and the opening 51 is aligned with the drill rod 4, and the drill rod 4 enters the filling device 5 from the opening 51, so that the matching installation of the filling device 5 and the drill rod 4 can be realized.
Preferably, the shape of the scrapers 53 is adapted to the threads of the drill rod 4, and the scrapers 53 engage the threads on the drill rod 4 when the scrapers 53 scrape the soil off the drill rod 4.
The engagement of the scraper 53 with the drill rod 4 allows for a better scraping action of the soil. It should be noted that the scraping action is required to be matched with the rotation of the screw, the screw rotation will bring the scraper 53 to generate the relative displacement in the screw axial direction, so that the scraper 53 needs to be reset after scraping certain soil, otherwise the scraper 53 will be lifted by the screw to cause damage. The reset may be elastic, for example, the scraper 53 has elasticity, and after the scraper ascends along with the rotation of the screw, the scraper will be elastically popped into the original position after being disengaged from the screw due to the elasticity.
To facilitate scraping, the end of the scraper blade 53 for the soil is wedge-shaped and forms a guide ramp 54 to guide the soil scraping position. The wedge-shaped structure is convenient to scrape by matching with elastic force, and the soil can be more easily applied with force.
In order to enable the soil sample storage tank to have an automatic transmission function and further improve the filling efficiency, a transmission rubber belt 55 with the length at least larger than the width of the two soil sample storage tanks 3 is arranged on the side surface of the transmission channel 52, and the transmission rubber belt 55 is driven by a motor drive and an auxiliary wheel drive to push the soil sample storage tanks 3 to move in the transmission channel 52; the width of transmission path 52 and soil sample storage jar 3 phase-match to cooperation transmission rubber tape 55 butt soil sample storage jar 3.
Through the motor rotation, cooperation auxiliary wheel installation and support transmission rubber belt 55, can let transmission rubber belt 55 be in the transmission state, transmission rubber belt 55 pastes the side surface of soil sample storage jar 3 this moment, can provide sufficient frictional force and promote soil sample storage jar 3, and the length of transmission rubber belt 55 is greater than two soil sample storage jar 3's width at least, that is to say, transmission rubber belt 55 can drive two soil sample storage jar 3 simultaneously, the problem that soil sample storage jar 3 was beaten in situ to the reduction appears.
The foregoing describes a scheme of using a flexible scraper 53, and a more stable embodiment is provided as follows, wherein a driving device 56 for driving the scraper 53 to approach or separate from the drill rod 4 is arranged in the filling device 5, the driving device 56 is associated with a motor corresponding to the transmission rubber belt 55, the driving device 56 is in a state of withdrawing the scraper 53 when the motor rotates, and the driving device 56 drives the scraper 53 to approach the drill rod 4 when the motor stops rotating.
Wherein the drive means 56 drive the scrapers 53 closer to or further away from the drill rod 4, i.e. a completely elastic return to the scraping position is avoided. And the close and far movement of the drive device 56 helps to improve the life of the blade 53. The motor of drive rubber belt 55 is correlated with drive arrangement 56, lets the motor just can carry out work when drive arrangement 56 is in the process of withdrawing scraper blade 53 or withdraws the state of scraper blade 53, avoids motor work and continues to scrape off soil when taking soil sample storage jar 3 to remove through drive rubber belt 55, appears soil and drops to inaccurate problem. Therefore, the matching state of the soil sample storage tank 3 and the scraper 53 can be further improved.
In fact, the specific structure of the scraper 53 can also be seen in the figure, the scraper 53 comprises a bracket and a scraper blade mounted on the bracket for moving up and down, the scraper blade is engaged with the screw thread, moves upwards while being carried by the screw thread while scraping the soil, continues to scrape the soil, slides downwards under the action of gravity when the driving device 56 retracts with the bracket, and waits for the next step of scraping the soil again. This structure can further improve the life.
Of course, if a more stable working condition and service life are desired, the skilled person can choose whether or not to add a cleaning device according to the needs, for example, flushing the scraper 53 after each sampling to ensure the smoothness of the up-and-down movement of the scraper, etc.
Furthermore, in order to make the fall of the soil more compatible with the soil sample storage tank 3. The driving device 56 and the motor are mutually related through a control chip, when the driving device 56 drives the scraper 53 to withdraw away from the drill rod 4, the motor synchronously drives the transmission rubber belt 55 to drive the soil sample storage tank 3 to move, and the scraper 53 is kept matched with the soil sample storage tank 3 until the scraper 53 is withdrawn to the right position. Control chip can adjust motor and drive arrangement 56 job-driven speed, lets soil sample storage jar 3 remove and carry out synchronous matching with scraper blade 53's removal, can improve the mating relation of soil and soil sample storage jar 3, if also there is soil to drop at the continuous removal in-process, can drop in the soil sample storage jar 3.
Preferably, the transfer passage 52 is further provided with a flushing device 6 for injecting running water into the transfer passage 52, and the driving rubber belt 55 and the motor are positioned higher than the bottom of the transfer passage 52 for flowing the running water.
Because the conveying channel 52 is used for moving the soil sample storage tank 3, the key of enabling the movement to be smoother is to keep clean, and the problem of soil accumulation can be reduced by flushing with running water. And the position of the driving rubber belt 55 and the motor is higher than the bottom of the transfer passage 52, that is, the bottom of the transfer passage 52 forms a water tank for flowing water, and the flowing water flushing effect is more stable.
