Description

Technical Field

[0001] The invention relates to the technical field of exploration and sampling, and in particular to a multifunctional geological exploration and efficient drilling device. Background Art

[0002] Geological exploration is mainly to identify the lithology, structure and hydrogeology of the strata in the investigation area, and to provide basic data for mineral exploration and engineering construction. In order to facilitate geological sampling, drilling equipment is required to carry out geological drilling.

When the sampling assembly completes sampling and resets, the closing assembly automatically completes the closing action of the closed door, so it effectively solves the problem of cumbersome use caused by the inability to form a linkage between the scraper and the sampling chamber, and then realizes that the closed door can be automatically closed after the sampling assembly completes sampling and resets, making the sampling operation more convenient.

[0004] When the soil viscosity or water content at the survey site is high, the soil after drilling by the drill bit is not in the form of small particles. However, when analyzing the physical and chemical properties of the soil, microbiological analysis and pollution detection, it is necessary to determine the soil particle composition, microbial community structure and pollutant content in the soil solution. Therefore, it is necessary to centrifuge and dehydrate the collected soil, so that the dehydrated soil and the separated soil solution can be tested separately, and the physical and chemical properties of the soil, microbiological analysis and pollution detection can be more convenient. However, the above technical solutions can only simply realize the sampling function. Not only can it not ensure the uniformity of the particle size of the soil sample before testing, but it can also not directly filter the soil solution or water from the soil.

[0034] In the embodiment of the present invention, when the electromagnet 231 is powered off, the electromagnet 231 loses its magnetic attraction to the driving gear 214 (the driving gear 214 is made of metal or magnetic material), and the elastic force of the return spring 232 drives the driving gear 214 to slide along the transmission tube 212 to a position meshing with the second tooth groove rail 31.

[0035] See also Figure 7 , Figure 8 and Fig.12 In one embodiment of the present invention, the rotating part 541 also includes a rotating plate 51, a rotating shaft 52, a third transmission gear 53 and a third key strip 56.

The tube core 621 is movably sleeved on the surface of the column core 611. The surface of the column core 611 and the inner side of the tube core 621 are respectively provided with a fourth key strip 612 and a fourth key groove. The fourth key strip 612 is slidably connected to the fourth key groove.

[0037] In the embodiment of the present invention, the number of the rotating shells 54 is three or four groups, the inner diameter of the accommodating shell 61 is larger than the outer diameter of the mesh cover 62 , and the length of the mesh cover 62 is smaller than the depth of the accommodating shell 61 .

[0038] Working principle: The driving motor is used to control the rotation of the drill shaft 111, the rigid tube shell 12 and the drill bit 13. When the drill bit 13 drills into the ground to a certain depth, the electromagnet 231 is first controlled to be powered off. Since the electromagnet 231 loses its magnetic attraction to the driving gear 214 after the power is turned off, the elastic force of the return spring 232 drives the driving gear 214 to slide along the transmission tube 212 to a position meshing with the second tooth groove rail 31. Since a limited end is provided at the end of the transmission tube 212, the driving gear 214 can be axially limited. The driving motor is used to control the rotation of the transmission tube 212, the driving gear 214 and the sealing cylinder 3, so that one of the first openings 32 is aligned with the radial sample inlet 125. Then, the electromagnet 231 is controlled to be energized. When the electromagnet 231 after being energized is magnetically attached to the driving gear 214, the driven gear 221 is connected to the driving gear 214 by transmission. The driving motor is used to control the transmission tube 212, the driving gear 214, the driven gear 221 and the rotating tube 411 to rotate. The rotating rotating tube 411 controls the open serpentine shell 421, the center rod 422, the first fixing ring 423, the radial rod 424 and the second fixing ring 425 to make reciprocating linear motion by means of the curved guide rail 413 and the sliding connection with the ball head 426. At the same time, the open serpentine shell 421 can be controlled to rotate by the second key bar 414, the second key groove and the center rod 422. The open serpentine shell 421 that rotates and reciprocates on both sides of the radial sample inlet 125 and the first opening 32 can not only break up the agglomerated or bonded soil, but also pull the broken up soil into the axial sample inlet 121. Since the rotating rotating tube 411 controls the rotating plate 51, the rotating shell 54 and the sample containing assembly 6 to rotate together with the rotating shaft 52 as the axis through the second transmission gear 412 and the third transmission gear 53, the soil can evenly enter the mesh cover 62 through the axial sample inlet 121. Since the rotating shell 54 rotating with the rotating shaft 52 as the axis is connected to the first toothed track 127 through the fourth transmission gear 55, the purpose of controlling the rotation of the rotating shell 54, the mesh cover 62 and the containing shell 61 is achieved. The centrifugal force generated by the rotating mesh cover 62 can increase the squeezing force between the soil and the mesh cover 62. The squeezing force can precipitate moisture from the soil, and use the filtering effect of the mesh cover 62 to filter the moisture into the containing shell 61. The moisture in the soil can be filtered into the containing shell 61, thereby achieving the purpose of sampling the soil solution. By performing physical and chemical analysis on the soil solution, it is convenient to detect pollutants in the soil. The principle of centrifugal dehydration is widely used in the field of studying soil moisture characteristics and sludge or sewage treatment, so it will not be described in detail. After the sampling is completed, the open serpentine shell 421 is first reset to the rigid tube shell 12 by using the driving module 2, and then the sealing tube 3 is controlled to rotate by using the driving module 2, so that the other first opening 32 is aligned with the radial sample inlet 125. At this time, the taking and releasing port 126 is aligned with the second opening 33. Then, the sampling module 4 and the rotating part 541 are controlled to move simultaneously by using the driving module 2. When the mesh cover 62 moves to the position of the axial sampling port 123, the user takes out the mesh cover 62 and the containing shell 61 in turn through the second opening 33 and the axial sampling port 123, so as to facilitate the sampling and detection of soil particles and soil solution at the same time.

[0039] In summary, (1) the present application utilizes an open serpentine shell 421 that rotates and reciprocates on both sides of the rigid tube shell 12, which can not only break up the agglomerated or sticky soil, but also pull the broken up soil into the sample holding component 6, thereby solving the problem of inconvenient sampling of soil that is highly viscous or easily agglomerated, and has the characteristic of facilitating sampling.

[0040] (2) The present application utilizes the driving module 2 to control the sampling of the open serpentine shell 421, and can also control the sample holding component 6 to rotate about the axis of the rotating part 541 and its own axis at the same time, which can not only evenly transport the soil to each sample holding component 6, but also use centrifugal force to filter the moisture in the soil into the holding shell 61, thereby facilitating the sampling and detection of soil particles and soil solution at the same time.

[0041] (3) The present application utilizes the driving module 2 to control the sealing tube 3 to rotate a number of angles in sequence, which can not only seal the rigid tube shell 12 when the drill bit 13 drills the soil, but also align the first opening 32 with the radial sample inlet 125 when sampling, and can also align the access port 126 with the second opening 33 when testing, and has the characteristics of easy adjustment and easy access to the sample holding component 6.
