Description
Technical Field
[0001] This utility model relates to the field of geological exploration equipment technology, and in particular to a geological exploration field sample collection device. Background Technology
[0002] In engineering construction, such as the construction of highways, railways, and dams, surveying and sampling can provide information on foundation stability, soil and rock mechanical properties, and assess potential geological hazard risks, such as landslides and debris flows. By analyzing the extracted samples, the lithology, thickness, bedding, and other characteristics of the strata can be determined, thereby inferring the morphology, scale, and spatial distribution of geological structures.
[0003] When sampling is conducted at the exploration site, a drill rod is used for sampling. The drill rod is rotated by a motor, so that the end of the drill rod is inserted into the soil layer. When the drill rod is pulled out of the soil layer, the compacted soil collected at the end of the drill rod is brought out. The compacted soil is then peeled off the drill rod, and the sample can be collected.
[0004] However, in actual operation, due to different sampling depth requirements, drill rods of matching length are often required. When deep soil sampling is required, long drill rods are needed. At this time, it is necessary to use hoisting equipment to lift the drill rod and then assemble it with the motor output end, which significantly increases the difficulty of on-site assembly of the drill rod. Therefore, this application proposes a geological exploration field sample collection device that can facilitate on-site assembly of drill rods. Utility Model Content
[0005] The purpose of this invention is to address the problem in the prior art that long drill pipes are difficult to assemble on-site, and to propose a geological exploration field sample collection device that facilitates on-site assembly of drill pipes.

[0007] A push rod placement frame is fixedly installed on a support frame, and a plurality of push rods are movably installed on the push rod placement frame;
[0008] A rotating rod is fixedly installed at the output end of a servo motor. A sampling drill bit is provided below the rotating rod. The top end of the push rod is engaged with the bottom end of the rotating rod, and the bottom end of the push rod is engaged with the top end of the sampling drill bit.
[0009] Optionally, the push rod placement frame includes a first positioning frame and a second positioning frame. The first positioning frame and the second positioning frame are both fixedly installed on a matching support frame. A limit frame and a bracket are fixedly installed together between the first positioning frame and the second positioning frame. The push rod is movably inserted into the limit frame and the bracket.
[0010] Optionally, the bracket includes a pushing part and a connecting part. One end of the pushing part is fixedly connected to a first positioning frame, and one end of the connecting part is fixedly connected to a second positioning frame. A plurality of rollers are rotatably mounted on the pushing part, and the bottom of the pushing rod rests on a matching roller.
[0011] Optionally, the bottom ends of the rotating rod and the push rod are fixedly equipped with locking blocks, and the top ends of the sampling drill bit and the push rod are chiseled with locking slots. The locking blocks are embedded in the matching locking slots and engaged with them.
[0012] Optionally, the card block has a slot, and a plug is fixedly installed on the inner side wall of the slot. The plug is inserted into the matching slot and engages with it.
[0013] Optionally, the motor mounting bracket includes a support plate, which is slidably mounted on the top of two support frames. A plurality of limiting rods are fixedly mounted on the top of the support plate, and a motor mounting plate is movably mounted on the plurality of limiting rods.

When it is necessary to increase the overall length of the drill rod, only the number of push rods needs to be increased.

[0034] Example
[0035] like Figures 1-5As shown, this utility model proposes a geological exploration field sample collection device, including a base 1. Two support frames 2 are fixedly installed on the top of the base 1. A motor mounting frame 5 is slidably installed on the top of both support frames 2. An adjustable servo motor 6 is located on the top of the motor mounting frame 5. A rotating rod 7 is fixedly installed at the output end of the servo motor 6. A push rod 8 is engaged at the bottom end of the rotating rod 7. A sampling drill bit 3 is engaged at the bottom end of the push rod 8. The sampling engagement structure of the rotating rod 7, the push rod 8, and the sampling drill bit 3 is integrated into one unit, facilitating disassembly and reassembly. The device is equipped with two support frames 2, each with a push rod placement frame 4. Several push rods 8 are movably mounted on the push rod placement frame 4. Placing multiple push rods 8 on the push rod placement frame 4 facilitates the addition of push rods 8 to the bottom of the rotating rod 7, making it easier to adjust the overall length of the drill rod. A cylinder 9 is fixedly mounted on the push rod placement frame 4. A push plate 91 is fixedly mounted on the output end of the cylinder 9. The cylinder 9 drives the push plate 91 to move laterally, which facilitates pushing the prepared push rods 8 to one side of the rotating rod 7, making it easy to snap the push rods 8 into place at the bottom of the rotating rod 7.
[0036] Furthermore, the push rod placement frame 4 includes a first positioning frame 41 and a second positioning frame 43. The first positioning frame 41 and the second positioning frame 43 are both fixedly installed on the matching support frame 2. A limit frame 42 and a bracket 44 are fixedly installed between the first positioning frame 41 and the second positioning frame 43. The limit frame 42 is used to limit the multiple push rods 8, ensuring that the push rods 8 can move stably laterally to one side of the rotating rod 7 under the push of the cylinder 9. The bracket 44 is used to support the bottom of the push rods 8 to prevent the push rods 8 from falling downward and improve their stability during lateral movement.
[0037] Secondly, the bracket 44 is composed of a push part 441 and a connecting part 442. One end of the push part 441 is fixedly connected to the first positioning frame 41, and one end of the connecting part 442 is fixedly connected to the second positioning frame 43, ensuring that the bracket 44 can be firmly installed between the first positioning frame 41 and the second positioning frame 43. Several rollers 443 are rotatably installed on the push part 441. The bottom of the push rod 8 placed on the bracket 44 is movably connected to the rollers 443. When the push rod 8 moves laterally, the rollers 443 assist it in rolling, ensuring that the push rod 8 can move smoothly to one side of the rotating rod 7.
[0038] Furthermore, both the bottom ends of the rotating rod 7 and the push rod 8 are fixedly equipped with locking blocks 10, and the top ends of the sampling drill bit 3 and the push rod 8 are chiseled with slots 11. When the push rod 8 is assembled with the rotating rod 7 and the sampling drill bit 3, the locking blocks 10 are embedded in the matching slots 11 and engaged with them. When the rotating rod 7 rotates, it can drive the push rod 8 and the sampling drill bit 3 to rotate stably, effectively improving the overall rotation stability of the drill rod.
[0039] Secondly, a slot 101 is drilled on the locking block 10, and a plug rod 111 is fixedly installed on the inner side wall of the locking slot 11. When the push rod 8, the rotating rod 7, and the sampling drill bit 3 are assembled into one piece, the plug rod 111 is inserted into the matching slot 101 and engaged with it. When it is necessary to pull out the sampling drill bit 3 and the push rod 8 inserted into the soil layer, it can prevent the sampling drill bit 3 from falling off the push rod 8, and at the same time avoid the push rods 8 from falling off each other and between the push rod 8 and the rotating rod 7.
[0040] It is worth noting that the motor mounting frame 5 includes a support plate 51, which is slidably mounted on the top of two support frames 2. Several limiting rods 52 are fixedly mounted on the top of the support plate 51, and a motor mounting plate 53 is movably mounted on the several limiting rods 52. The servo motor 6 is fixedly mounted on the top of the motor mounting plate 53. Handheld brackets 54 are fixedly mounted on the two outer side walls of the motor mounting plate 53 that are far apart. When the operator holds the handheld brackets 54, he can not only drive the servo motor 6 to move downward, but also drive the support plate 51 to move laterally. When it is necessary to insert the drill rod into the soil layer, the servo motor 6 is driven downward, so that the sampling drill bit 3 can be inserted into the soil layer in a rotating state for easy sampling. When it is necessary to increase the number of push rods 8, the support plate 51 is first pushed laterally to disengage the rotating rod 7 from the push rod 8 at its bottom end, and then the servo motor 6 is pushed upward. Sufficient space is reserved between the rotating rod 7 and the push rod 8 inserted into the soil layer to facilitate the addition of a new push rod 8 at the bottom end of the rotating rod 7, which facilitates the adjustment of the overall length of the drill rod.
[0041] In this embodiment, the rotating rod 7, the push rod 8, and the sampling drill bit 3 are stably assembled into one unit through the engaging connection between the locking block 10 and the locking slot 11. When the servo motor 6 drives the rotating rod 7 to rotate, the push rod 8 and the sampling drill bit 3 can rotate accordingly. At this time, the operator holds the holding bracket 54 and pulls it downward, which in turn drives the servo motor 6 to move downward, ensuring that the sampling drill bit 3 and the push rod 8 installed at its top can be inserted into the soil layer in a rotating state, which facilitates the sampling drill bit 3 to collect samples. After the soil sample in the soil layer is pressed into the sampling drill bit 3, the operator pushes the motor mounting plate 53 upward, which drives the sampling drill bit 3 and the push rod 8 to move upward, which can pull the sampling drill bit 3 out of the soil layer. Then, the soil sample collected in the sampling drill bit 3 can be peeled off, which facilitates the collection of samples.
[0042] When the sampling depth increases and the overall length of the drill rod (composed of the integrated rotating rod 7, push rod 8, and sampling drill bit 3) needs to be increased, the operator first pushes the support plate 51 laterally, causing it to slide laterally at the top of the support frame 2. This allows the rotating rod 7 to move laterally. After the bottom of the rotating rod 7 disengages from the push rod 8 below it, the motor mounting plate 53 is pushed upwards, which in turn moves the servo motor 6 and the rotating rod 7 upwards. This ensures that there is sufficient clearance between the rotating rod 7 and the push rod 8 below it, providing enough installation space for the subsequent installation of a new push rod 8. The cylinder 9 drives the push plate 91 to move laterally, which in turn pushes multiple push rods 8 that are placed on the push rod placement frame 4 to move laterally. When the push rod 8 on the side away from the cylinder 9 moves to the side of the rotating rod 7, the top end of the push rod 8 engages with the bottom end of the rotating rod 7. The bottom end of the newly added push rod 8 can engage with the top end of the push rod 8 that has already been inserted into the soil layer, thereby increasing the overall length of the drill rod. It can be quickly assembled on the exploration site, which can not only cope with sampling operations with different depth requirements, but also makes the assembly and disassembly of the drill rod easy, effectively improving the convenience of on-site assembly of the drill rod.
[0043] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
