Description

It is an investigation and research work on the geological conditions such as rocks, stratigraphic structures, minerals, groundwater, landforms, etc. in a certain area by using geological exploration methods such as surveying and mapping, geophysical exploration, geochemical prospecting, drilling, pit exploration, sampling testing, and geological remote sensing based on the needs of economic construction, national defense construction, and scientific and technological development.

[0003] At present, when a sampling device is used for drilling sampling, the sample is usually taken out through a tubular drilling rod. However, after the sampling is completed, the sample taken out is often a continuous long strip sample, which makes it difficult to distinguish the specific samples of each soil layer depth during detection. Therefore, before the detection, it is necessary to manually select samples of the required depth section again, which not only increases the complexity of the operation, but also is not conducive to efficient detection. In addition, when taking out the sample inside the drilling rod, it is usually necessary to use external knocking or other methods to push the sample. This operation is not only cumbersome, but also reduces the collection efficiency, and is easy to damage the drilling rod, shortening its service life. Summary of the invention

DETAILED DESCRIPTION

[0035] 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.

[0036] The embodiment provides a geological exploration and collection device for mineral development, such as Figure 1-Figure 6 As shown, it includes a base 1, a guide plate 2, a guide column 21, a mounting frame 3, a driving motor 4, a drill bit 8 and a sampling assembly. The left and right sides of the top of the base 1 are connected to the guide plates 2, and the two guide plates 2 are symmetrically arranged. The front and rear sides of the guide plates 2 are connected to the guide columns 21. The mounting frame 3 is slidably connected between the guide plates 2 on both sides. The mounting frame 3 can slide up and down along the guide plate 2. The driving motor 4 is installed in the middle position of the mounting frame 3. The base 1 is provided with a driving mechanism for driving the mounting frame 3 to rise and fall. The sampling assembly is provided with a group of connecting mechanisms, sampling mechanisms and docking mechanisms that are sequentially connected to the sampling assembly from top to bottom. The driving motor 4 is connected to the connecting mechanism of the sampling assembly, and the drill bit 8 is installed on the docking mechanism.

[0037] like Figure 2As shown, the driving mechanism includes a reduction motor 51 and a threaded rod 52. The reduction motors 51 are installed on both sides of the top of the base 1. The output shaft of each reduction motor 51 is connected to a threaded rod 52. The threaded rod 52 extends vertically upward, and the upper and lower ends of the threaded rod 52 are rotatably connected to the guide plate 2 through a support plate. The threaded rod 52 is threadedly matched with the mounting frame 3 so that the threaded rod 52 can drive the mounting frame 3 to move up and down through the thread when rotating.

[0038] like Figure 2 and Figure 3 As shown, the connecting mechanism includes a connecting end 61, a rotating sleeve 62, a connecting column 63, a connecting sleeve 64 and a docking rod 65. The output shaft of the drive motor 4 is connected to the connecting end 61, and the rotating sleeve 62 is rotatably connected to the connecting end 61. A connecting column 63 is installed at the bottom of the rotating sleeve 62. The connecting column 63 is located in the middle position inside the connecting end 61 and can rotate inside the connecting end 61. The bottom of the connecting end 61 is connected to a connecting sleeve 64 through a thread, and the connecting sleeve 64 is rotatably connected to the docking rod 65. When the connecting sleeve 64 and the connecting end 61 are connected, the connecting column 63 can be inserted into the docking rod 65, so that the connecting column 63 can drive the docking rod 65 to rotate when rotating.

[0039] like Figure 3-Figure 5 As shown, the sampling mechanism includes a sampling sleeve 71, a gear rack 72, a sampling plate 73 and a transmission gear 74. The bottom of the connecting sleeve 64 is connected to the sampling sleeve 71 by a thread. The gear rack 72 is rotatably connected inside the sampling sleeve 71. When the connecting sleeve 64 is connected to the sampling sleeve 71, the connecting column 63 can be inserted into the gear rack 72 so that the connecting column 63 can drive the gear rack 72 to rotate when it rotates. A plurality of sampling plates 73 are rotatably connected to the sampling sleeve 71 at uniform intervals along the circumferential direction. The upper and lower sides of the sampling plate 73 are connected to transmission gears 74, and the transmission gear 74 is meshed with the gear rack 72, so that the rotation of the gear rack 72 can drive the transmission gear 74 to rotate, thereby driving the sampling plate 73 to unfold.

[0040] like Figure 6As shown, the docking mechanism includes a docking sleeve 91, a feed plate 92, a docking block 94 and a connecting plate 93. The bottom of the sampling sleeve 71 is connected to the docking sleeve 91. The drill bit 8 and the connecting sleeve 64 can be spliced ​​at the bottom of the docking sleeve 91 through threads. The feeding plate 92 is slidably connected in the docking sleeve 91. The bottom of the feeding plate 92 is provided with a docking block 94. When the connecting sleeve 64 is docked to the bottom of the docking sleeve 91, the docking block 94 can be plugged into the top of the docking rod 65. The feeding plate 92 A connecting plate 93 is connected to the top. When the docking sleeve 91 and the sampling sleeve 71 are spliced, the connecting plate 93 is inserted into the sampling sleeve 71, located inside the gear frame 72 and is slidably connected to the gear frame 72. At this time, the docking rod 65 is also inserted into the connecting plate 93. At this time, the sample collected by the sampling plate 73 will fall into the docking sleeve 91 and the sampling sleeve 71 for collection. When the sampling sleeve 71 and the docking sleeve 91 are subsequently removed, the connecting plate 93 and the feeding plate 92 are pulled up to take out the sample, which makes it more convenient to take out the sample.

[0041] When it is necessary to collect geological samples, the present collection device can be used. During use, the present device is first placed on the land to be sampled, and then the reduction motor 51 is controlled to drive the mounting frame 3 to move downward through the threaded rod 52, thereby driving the drive motor 4 to move downward. At this time, the drive motor 4 can be controlled to drive the connecting end 61, the connecting sleeve 64, the sampling sleeve 71, the docking sleeve 91 and the drill bit 8 to rotate. The drill bit 8 can move downward while rotating, thereby drilling into the land. After the drill bit 8 is probed to a suitable depth so that the sampling sleeve 71 is located at the sampling depth, the reduction motor 51 and the drive motor 4 can be controlled to stop running. At this time, the rotating sleeve 62 is rotated to rotate. When rotating, the rotating sleeve 62 can drive the connecting column 63 to rotate, and when the connecting column 63 rotates, it can drive the docking rod 65 to rotate. When the docking rod 65 rotates, it can drive the gear frame 72 to rotate. When the gear frame 72 rotates, it can rub the transmission gear 74 to rotate, thereby driving the sampling plate 73 to unfold. At this time, the driving motor 4 is continued to be controlled to drive the sampling sleeve 71 to rotate. When the sampling sleeve 71 rotates, it can drive the sampling plate 73 to rotate, and the sample in the soil layer is dialed into the sampling sleeve 71 and the docking sleeve 91, thereby achieving the effect of sampling the geological sample. After the sampling is completed, the reduction motor 51 is controlled to drive the threaded rod 52 to rotate in the opposite direction to lift the mounting frame 3.

[0042] In the actual operation process, the sampling components can be set in multiple groups according to the sampling requirements. When multiple groups of sampling components are set, the driving motor 4 is connected to the connecting mechanism of the first group of sampling components at the top, and the drill bit 8 is installed on the docking mechanism of the sampling component at the bottom. The docking mechanism at the lower end of each group of sampling components in the middle is connected to the upper end connecting mechanism of the adjacent sampling component; specifically, the connecting sleeve 64 is spliced ​​again below the sampling component docking sleeve 91, and the sampling sleeve 71 and the docking sleeve 91 are spliced ​​below the subsequently spliced ​​connecting sleeve 64, and the drill bit 8 is spliced ​​at the docking sleeve 91 at the bottom, and so on. The sample collection work of different depths can be realized, and the height of the connecting sleeve 64 can also be set to be different, so as to facilitate more diversified depth collection work. When the sample needs to be taken out, the sampling sleeve 71 and the docking sleeve 91 are removed, and then the feeding plate 92 and the connecting plate 93 are pulled up, so that the sample can be taken out, so as to realize the sample removal work. In this way, the device can be used to collect samples in geological exploration work, and samples of different depths can be collected at the same time during collection, the collection range is wider, and the operation is more convenient.

[0043] like Figure 7 and Figure 8 As shown, the collecting device provided in the embodiment also includes a transmission mechanism, which includes a sliding frame 101, an adjusting screw 102, a locking frame 103, a sleeve 104, an extension plate 105, a contact ball 106 and an elastic member 108. The front side of the guide plate 2 is slidably connected with the sliding frame 101, and the sliding frame 101 can slide up and down along the guide plate 2. The middle of the front side of the sliding frame 101 is rotatably connected with the adjusting screw 102, and the front side of the sliding frame 101 is slidably connected with the locking frame 103. The locking frame 103 is threadedly matched with the adjusting screw 102, so that the rotation of the adjusting screw 102 can drive the locking frame 103 to move through the thread, so that the locking frame 103 presses against the guide plate 2 on the front side. Toward the column 21, the sliding frame 101 is fixed, the connecting end 61 is slidably connected with a sleeve 104, the sleeve 104 is connected with an extension plate 105, the sliding frame 101 is located at the moving track of the extension plate 105, the sleeve 104 is connected with a contact ball 106, the outer ring of the rotating sleeve 62 is provided with a guide groove 107, one end of the guide groove 107 extends to the bottom of the rotating sleeve 62 and is located at the moving track of the contact ball 106, so that the contact ball 106 can enter the guide groove 107 when moving upward and squeeze the rotating sleeve 62 to rotate through the guide groove 107, an elastic member 108 is connected between the connecting column 63 and the connecting end 61, and the elastic member 108 is a torsion spring.

[0044] When the connecting end 61 moves downward, the sleeve 104 and the extension plate 105 can be driven to move downward. When the extension plate 105 moves downward to contact the sliding frame 101, the extension plate 105 and the sleeve 104 stop moving. At this time, the connecting end 61 continues to move downward, and the sleeve 104 moves upward relative to the connecting end 61. When the sleeve 104 moves upward, it drives the contact ball 106 to move upward. The contact ball 106 moves upward and can enter the guide groove 107 and squeeze the guide groove 107, thereby driving the rotating sleeve 62 to rotate, and the elastic member 108 is compressed. The effect of automatically driving the rotating sleeve 62 to rotate can be achieved, and there is no need to manually operate the rotating sleeve 62 to rotate, which is more convenient to operate. In the actual operation process, if it is necessary to control the rotation depth of the rotating sleeve 62, the adjusting screw 102 can be rotated so that the locking frame 103 no longer abuts against the guide column 21, and then the locking frame 103 and the sliding frame 101 are pulled up and down for adjustment. After adjusting to the appropriate height, the adjusting screw 102 is rotated in the opposite direction so that the locking frame 103 abuts against the guide column 21, and the sliding frame 101 is fixed.

When the connecting sleeve 64, the sampling sleeve 71, the drill bit 8 and the docking sleeve 91 move upward, the conical hole can scrape off the soil attached to the connecting sleeve 64, the sampling sleeve 71, the drill bit 8 and the docking sleeve 91, so as to clean the connecting sleeve 64, the sampling sleeve 71, the drill bit 8 and the docking sleeve 91.

[0046] like Fig. 9 and Fig.10 As shown, the collecting device provided in the embodiment also includes a cleaning mechanism, which includes a connecting ring 121, a liquid injection pipe 122 and a liquid spraying pipe 123. The bottom of the scraper plate 111 is connected to the connecting ring 121, and a plurality of liquid injection pipes 122 are evenly spaced along the circumferential direction on the connecting ring 121.
