Description

Technical Field

[0001] This invention relates to the technical field of drilling sample collection, and more particularly to a geological drilling classification and sampling collection box. Background Technology

[0002] During geological exploration and surveys, drilling samplers are used to sample the soil layers in mining areas. Because some geological drilling depths are shallow and the locations are inaccessible in the field, and core boxes are large and difficult to transport, small drills are used. The samples are then removed from the core tube, sorted and packaged in plastic bags according to the drilling depth, and numbered before being sent back to the laboratory for analysis. However, the samples taken from the core tube are often not continuous and consist of relatively soft soil layers. Although they are arranged in the order they came out of the core tube, transferring them to the plastic bags inevitably leaves some fragments on the ground. These fragments are difficult to retrieve completely, affecting subsequent analysis of the soil layers in the mining area. Furthermore, the plastic bags are easily damaged and can break, leading to sample loss. During handling, carelessness can easily cause the samples to be out of order, requiring manpower to search and correct them according to their numbers. Summary of the Invention

[0026] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example

[0027] Reference Figure 1-3 The first embodiment of the present invention provides a geological drilling classification sampling collection box. This device includes a collection unit 100, including a shell 101, a shell cover 102 detachably installed on the upper end of the shell 101, the shell cover 102 and the shell 101 being threadedly connected, a support box 103 connected to the lower end of the shell 101, and the support box 103 being a circular box, as well as a collection component 104 and a backflushing component 105 disposed inside the shell 101. The backflushing component 105 can be a blower that blows air into the collection component 104 to backflush the collection component 104.

[0028] The collecting component 104 includes a support plate 104a rotatably disposed inside the shell 101, support slots 104b evenly distributed in a ring on the support plate 104a, a collecting tube 104c with one end inserted into the support slot 104b, the length of a single collecting tube 104c being greater than the length of the core tube, and the outer walls of the multiple collecting tubes 104c being sequentially labeled 1, 2, 3, ..., a drive rod 104d connected through the center of the support plate 104a, a drive hole 104e opened at the center of the top of the shell 102, with the upper end of the drive rod 104d passing through the drive hole 104e, a sealing ring connected to the inner wall of the drive hole 104e, and the drive rod 104d being rotatably connected to the inner wall of the sealing ring, a support assembly 104f disposed at the lower end of the support plate 104a, and a feeding assembly 104g disposed at the upper end of the shell 102.

[0029] The support assembly 104f includes multiple support rollers 104f-1 that are uniformly and equidistantly connected in a ring at the lower end of the support plate 104a, and a caster wheel 104f-2 installed at the other end of the support rollers 104f-1. The caster wheel 104f-2 is rotatably connected to the top of the support box 103. The caster wheel 104f-2 supports the support plate 104a. When the support plate 104a rotates, the support rollers 104f-1 drive the caster wheel 104f-2 to rotate on the top of the support box 103.

[0030] The feeding assembly 104g includes a feeding hopper 104g-1 that is connected through the housing 102, and a hopper cover 104g-2 that is movably inserted into the feeding hopper 104g-1. The hopper cover 104g-2 has an inverted conical cross section. The distance between the feeding hopper 104g-1 and the hopper cover 104g-2 is 1cm. It also includes multiple anti-detachment blocks 104g-3 that are uniformly connected in a ring on the side wall of the hopper cover 104g-2. The other end of the anti-detachment block 104g-3 is movably attached to the inner wall of the feeding hopper 104g-1.

[0031] During use, when collecting samples, first remove the lid 104g-2 from the feed hopper 104g-1. Apply rotational force to the drive rod 104d, which drives the support plate 104a to rotate. When the support plate 104a rotates, it drives the collection tube 104c to rotate synchronously, so that the collection tube 104c (number 1) rotates directly below the discharge end of the feed hopper 104g-1. Then, vertically insert the core tube into the feed hopper 104g-1 and tap the core tube to allow the sample in the core tube to pass directly through the feed hopper 104g-1 into the collection tube 104c (number 1). Afterward, remove the core tube, and then rotate the drive rod 104d to drive the support plate 104a to rotate, so that the collection tube 104c (number 2) rotates directly below the discharge end of the feed hopper 104g-1. Rotate the core tube directly below the discharge end of the feed hopper 104g-1, vertically insert the core tube into the feed hopper 104g-1, and tap the core tube to allow the sample in the core tube to pass directly through the feed hopper 104g-1 into the collection tube 104c (number 2). Repeat the above steps to collect the sample from each core tube individually. Collect core samples from different depth layers through different collection tubes 104c. Regardless of whether the sample in the core tube is continuous, it will enter the collection tube 104c intact and directly, avoiding the loss of some samples during transfer. The collection tube 104c is protected by the shell 101 and is not easily damaged. The samples are distributed sequentially in the same direction in multiple collection tubes 104c, without causing confusion. Example

[0032] Reference Figure 1-5 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the backflush component 105 includes a speed-increasing gearbox 105a connected to the center of the upper end of the support box 103, and the lower end of the drive rod 104d is connected to the input shaft of the speed-increasing gearbox 105a; a push assembly 105b disposed on the drive rod 104d; an air guide hole 105c opened on the top of the support box 103; a fan blade 105d connected to the output shaft of the speed-increasing gearbox 105a, and the fan blade 105d is located in the air guide hole 105c; an air inlet 105e opened on the wall of the support box 103; a protective assembly 105g disposed on the air inlet 105e, the protective assembly 105g can be a filter plate to filter the air entering the support box 103; and a backflush component 105f disposed in the collection pipe 104c.

[0033] Backflush assembly 105f includes a support ring 105f-1 connected to the inner wall of collection pipe 104c, a support frame 105f-2 connected to the inner wall of collection pipe 104c, a support rod 105f-3 movably passing through the support frame 105f-2, and a support block 105f-4 connected to the upper end of the support rod 105f-3. The support block 105f-4 and the support ring 105f-1 are matched and sealed and slidably connected. Spring 105f-5 between 105f-4 and support frame 105f-2, spring 105f-5, and spring 105f-5 sleeved on support rod 105f-3; and top sealing component 106 provided on backflushing component 105, top sealing component 106 can be a sliding plate, the inner top of housing 102 remains in a movable fit so that air in collection pipe 104c can be discharged when collection pipe 104c corresponds to feed hopper 104g-1.

[0034] During use, after a sample is collected by a collection tube 104c, the lid 104g-2 is placed inside the feed hopper 104g-1. Then, the drive rod 104d drives the support plate 104a to continue rotating. The rotation of the drive rod 104 also drives the input shaft of the speed-increasing gearbox 105a to rotate. After being accelerated by the speed-increasing gearbox 105a, the output shaft of the speed-increasing gearbox 105a drives the fan blade 105d to rotate at high speed in the air guide hole 105c, thereby drawing outside air into the support box 103 through the air inlet 105e, and then into the shell 101 through the air guide hole 105c. The pressure inside the shell 101 continuously increases. When the next collection tube 104c begins to overlap with the feed hopper 104g-1, the air inside the shell 101 exerts pressure on the support block inside the collection tube 104c. 105f-4 applies an upward pushing force, and after the support block 105f-4 is subjected to force, it stretches the spring 105f-5 and drives the support block 105f-4 to disengage from the support ring 105f-1. After the support block 105f-4 disengages from the support ring 105f-1, air in the shell 101 rushes into the collection tube 104c and rushes out at high speed through the gap between the feed hopper 104g-1 and the hopper cover 104g-2. When the air flows, it not only carries away the residual dust in the collection tube 104c, but also blows out the sample debris adhering to the inner wall of the feed hopper 104g-1, cleaning the collection tube 104c and the feed hopper 104g-1. Then the hopper cover 104g-2 is removed. After the collection tube 104c and the feed hopper 104g-1 are aligned, the drive rod 104d stops rotating.

[0035] Compared to Embodiment 1, the pushing assembly 105b further includes a pushing hole 105b-1 disposed on the wall of the drive rod 104d, and a pushing rod 105b-2 disposed through the pushing hole 105b-1. The pushing rod 105b-2 is located directly above the housing 102. Applying a pushing force to the pushing rod 105b-2 can push the drive rod 104d to rotate with less effort.

[0036] The remaining structure is the same as that in Example 1. Example

[0037] Reference Figure 1-5 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the protective component 105g includes a filter screen 105g-1 installed on the air inlet 105e and a filter cover 105g-2 connected in the support box 103. The air guide hole 105c is located directly above the filter cover 105g-2. A drive shaft 105g-3 is connected to the center of the lower end of the fan blade 105d. Multiple drive ropes 105g-4 are connected in a ring at equal intervals on the shaft wall of the drive shaft 105g-3. The other end of the drive ropes 105g-4 is connected to a striking ball 105g-5.

[0038] During use, the air entering the air inlet 105e is initially filtered by the filter screen 105g-1, and then the air entering the shell 101 through the filter cover 105g-2 undergoes secondary filtration to prevent dust and impurities from adhering to the collection pipe 104c and the feed hopper 104g-1. The filtered dust and impurities are blocked on the outside of the filter cover 105g-2. When the fan blade 105d rotates, it drives the drive shaft 105g-3 to rotate, and applies centrifugal force to the striking ball 105g-5 through the drive rope 105g-4, causing the striking ball 105g-5 to be thrown up. The striking ball 105g-5 continuously hits the filter cover 105g-2, causing the filter cover 105g-2 to vibrate and shake off the dust adhering to the outside of the filter cover 105g-2, preventing dust from clogging the mesh on the filter cover 105g-2 and affecting the ventilation of the filter cover 105g-2. The filter screen 105g-1 is located on the outside, making it easy to clean.

[0039] The remaining structure is the same as that in Example 2. Example

[0040] Reference Figure 1-6This is the fourth embodiment of the present invention. This embodiment differs from the third embodiment in that: the top sealing component 106 includes a top sealing tube 106a with one end inserted into the inner wall of the collection tube 104c, and the collection tube 104c and the top sealing tube 106a are slidably connected in a sealed manner; a compression spring 106c is disposed between the top sealing tube 106a and the collection tube 104c; the two ends of the compression spring 106c are kept abutting against the top sealing tube 106a and the collection tube 104c but not connected, so as to facilitate the removal of the top sealing tube 106a from the collection tube 104c; and the compression spring 106c is sleeved on the top sealing tube 106a; and a sealing assembly 106b is connected to multiple top sealing tubes 106a.

[0041] The sealing assembly 106b includes a sealing ring plate 106b-1 movably mounted on multiple top sealing tubes 106a, and a fixing ring hole 106b-2 connected to the lower end of the sealing ring plate 106b-1 at the corresponding position of the top sealing tube 106a. The upper end of the top sealing tube 106a is inserted into the fixing ring hole 106b-2, and the two are matched. The sealing ring plate 106b-1 rests against the inner top of the housing 102, ensuring that the top sealing tube 106a and the collection tube 104c are in contact with the housing. The top of the cover 102 is sealed together. When the support plate 104a drives the collection pipe 104c and the top sealing pipe 106a to rotate, the top sealing pipe 106a is only connected to the feed hopper 104g-1 when the top sealing pipe 106a corresponds to the feed hopper 104g-1. This replaces the wear caused by the rotation of the top sealing pipe 106a. The sealing ring plate 106b-1 is detachably connected to the top sealing pipe 106a, and the sealing ring plate 106b-1 can be replaced.

[0042] During use, the collecting pipe 104c is inserted into the support plate 104a, the top sealing pipe 106a is inserted into the collecting pipe 104c, and the sealing ring plate 106b-1 is then placed on the top sealing pipe 106a. Subsequently, the housing 102 is installed on the housing 101. The housing 102 applies downward pressure to the sealing ring plate 106b-1, thereby pushing the top sealing pipe 106a to move downward in the collecting pipe 104c, compressing the compression spring 106c. Under the action of the restoring force of the compression spring 106c, the sealing ring plate 106b-1 is pushed against the inner top of the housing 102. When the top sealing pipe 106a rotates, it drives the sealing ring plate 106b-1 to rotate synchronously. Only when the top sealing pipe 106a and the feed hopper 104g-1 correspond can the top sealing pipe 106a be connected to the feed hopper 104g-1, ensuring the sealing effect. Moreover, the sealing ring plate 106b-1 can be replaced.

[0043] Compared to Embodiment 3, the sealing ring plate 106b-1 further features two symmetrically staggered "L"-shaped annular grooves 106b-3 on its inner and outer annular walls. An elastic sealing gasket 106b-4 is engaged within each of the two annular grooves 106b-3. The elastic sealing gasket 106b-4 covers the upper end of the sealing ring plate 106b-1, and its upper end is positioned on the top of the inner cover of the housing 102. An inlet hole 106b-5 is provided on the elastic sealing gasket 106b-4 corresponding to the position of the top sealing tube 106a. The elastic sealing gasket 106b-4 improves the sealing effect between the sealing ring plate 106b-1 and the housing 102. Furthermore, the engagement of the elastic sealing gasket 106b-4 with the two staggered annular grooves 106b-3 enhances the tightness of the connection between the elastic sealing gasket 106b-4 and the sealing ring plate 106b-1.

[0044] The remaining structure is the same as that in Example 3.
