Description

Technical Field

[0001] The invention relates to the technical field of deep sampling, and in particular to a deep sampling device for geological engineering. Background Art

[0002] In the field of geological engineering, whether it is geological exploration, geological disaster assessment, or geological survey work in the early stages of various engineering construction, collecting and analyzing soil samples at different depths is an extremely critical link. By analyzing the collected soil samples, we can understand important information such as underground geological structure, soil composition, physical and mechanical properties, and provide reliable data support for subsequent geological research, engineering planning and construction. Therefore, a sampling device that can efficiently and accurately obtain deep soil samples that meet the requirements is particularly important.

[0003] In the prior art, traditional handheld soil sampling devices often lack an effective soil discharge mechanism when drilling underground to obtain deep samples. In the process of drilling into the soil, the drilled soil tends to accumulate in the borehole. As the depth of the borehole increases, the accumulated soil will greatly hinder the continued descent of the sampling device, making it difficult to smoothly reach the sampling position at the specified depth. Moreover, this disordered accumulation will also destroy the regularity of the hole, so that the samples collected subsequently may be affected by the mixing of the surrounding disturbed soil, and the purity and representativeness of the samples cannot be guaranteed, which is not conducive to accurate sampling.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention provides a spiral drum, which rotates rapidly under the drive of a driven gear, and the operator holds the handle to press the spiral drum down toward the soil position of the sampling point. The spiral drum, with its own spiral structure and in coordination with the soil-breaking component, can drive the excess soil upward along its outer side and out of the hole during rotation, so that the hole continues to deepen until the bottom end of the spiral drum can smoothly reach the sampling location at a specified depth. This function of bringing out excess soil not only avoids excessive accumulation of soil in the hole that hinders the device from continuing to descend, but also ensures the regularity of the hole, creating good conditions for accurate sampling.

[0016] 2. The present invention provides a soil-breaking component. The rotating block of the soil-breaking component rotates together with the sampling component as a whole. The soil-breaking block fixedly connected at the bottom cuts and crushes underground soil layers and other geological structures during rotation, and cooperates with the punching action of the spiral drum to further enhance the ability to destroy soil and other geological structures, more efficiently open up a channel for the sampling device to enter, and help the spiral drum to drill into the ground smoothly and bring out excess soil, ensuring that the sampling location at the specified depth can be reached.

[0017] 3. The present invention provides a ground-breaking component. The arc groove at the bottom of the rotating block helps to divert the broken geological debris to a certain extent during the ground-breaking process, so as to avoid excessive accumulation of the geological debris in the hole and hinder the device from continuing to move downward. The threaded groove on the side wall can further enhance the interaction between the ground-breaking component and the surrounding geological structure when drilling into the ground, thereby improving the ground-breaking efficiency and cooperating with the spiral drum to complete the drilling and deepening work.

[0018] 4. The present invention provides a sampling assembly. When the bottom of the spiral drum reaches the specified position, the telescopic rod fixed at the bottom of the limiting swivel extends, so that the connecting plate drives the storage component to move downward as a whole. At this time, the storage drum slides out from the bottom of the spiral drum, and at the same time, the slider drives the hollow rod and the connecting frame to move downward as a whole, so that the storage component is in a state where it can directly contact and obtain the soil sample to be collected, ensuring that the subsequent sampling operation can be carried out smoothly.

[0019] 5. The present invention provides a limit sleeve. When the limit sleeve is rotated, the limit sleeve drives the rotating rod to rotate together. At this time, the bottom end of the rotating rod drives the threaded sleeve to rotate along the inner side of the limit block, so that the threaded rod gradually slides out of the threaded sleeve. At this time, the threaded rod is driven by the connecting rod to move as a whole with the conical block, thereby adjusting the distance between the conical block and the annular block, thereby changing the volume of the sampling area. During the sampling process, the amount of soil samples collected each time can be accurately controlled according to actual geological research objectives, analysis accuracy requirements and other factors, thereby improving the pertinence and effectiveness of sampling and ensuring that the obtained samples are more in line with the requirements of subsequent research.

[0020] 6. The present invention sets an adjustment component. When the telescopic cylinder is extended, the pressure plate presses on the surface of the connecting frame and presses the connecting frame downward. At this time, the connecting frame drives the hollow rod to move downward. At the same time, the hollow rod presses the annular block downward through the slider and the sliding rod, so that the compression spring is compressed. At the same time, the annular block, the connecting rod and the conical block slide out from the bottom of the storage tube. Among them, the conical design of the conical block helps to insert it into the surrounding soil to be collected more smoothly. The resistance encountered during insertion is reduced. At this time, the soil can adhere to the area between the conical block and the annular block, realizing the operation of the soil sample entering the sampling area and completing the sample collection action. During the whole process, all components cooperate with each other, and mechanical transmission and force transmission are used to accurately control the action of the sampling component to ensure that the soil sample can be obtained smoothly.

[0021] 7. The present invention arranges a compression spring. When the telescopic cylinder is reset, the conical block and the annular block can return to the storage tube under the elastic force of the compression spring, so as to achieve proper storage of the soil to be collected, prevent the sample from being lost or contaminated during transfer, transportation and subsequent analysis, and facilitate the subsequent removal of the sample from the storage tube for various tests and studies according to the standardized geological analysis process, thereby ensuring the integrity of the entire sampling work and the effectiveness of the sample.

[0041] Working principle:

[0042] When in use, when the operator holds the device for sampling, he / she holds the handle on the outside of the housing 1 to stabilize the operating device. The driving motor 4 located inside the housing 1 is powered on to start working, and the output end of the driving motor 4 drives the driving gear 5 to rotate. Since the driving gear 5 is meshed with the driven gear 6, the rotation of the driving gear 5 will be transmitted to the driven gear 6, and then the sampling assembly 2 fixedly connected thereto will start to rotate, providing initial power for the entire handheld sampling process, so that the device can collect samples at the target geological location.

[0043] During this process, the spiral drum 21 rotates rapidly under the drive of the driven gear 6, and the operator holds the handle to press the spiral drum 21 down toward the soil position of the sampling point. The spiral drum 21, with its own spiral structure and in coordination with the soil-breaking component 3, can drive the excess soil upward along its outer side and out of the hole during the rotation process, so that the hole continues to deepen until the bottom of the spiral drum 21 can smoothly reach the sampling location at the specified depth. This function of taking out excess soil not only avoids excessive accumulation of soil in the hole that hinders the device from continuing to move downward, but also ensures the regularity of the hole, creating good conditions for accurate sampling.

[0044] The rotating block 31 of the soil-breaking component 3 rotates together with the sampling component 2 as a whole. The soil-breaking block 32 fixedly connected to the bottom thereof cuts and breaks the underground soil layer and other geological structures during rotation, and cooperates with the punching action of the spiral drum 21 to further enhance the ability to destroy geological structures such as soil, more efficiently open up a channel for the sampling device to enter, and help the spiral drum 21 to drill into the ground smoothly and bring out excess soil, ensuring that the sampling location at the specified depth can be reached.

[0045] Among them, the arc groove 33 opened at the bottom of the rotating block 31 helps to divert the broken geological debris and the like during the ground breaking process to prevent them from excessively accumulating in the hole and hindering the device from continuing to descend, while the threaded groove 34 opened on the side wall can further enhance the interaction between the ground breaking component 3 and the surrounding geological structure when drilling into the ground, thereby improving the ground breaking efficiency and cooperating with the spiral drum 21 to complete the drilling and deepening work.

[0046] When the bottom of the spiral drum 21 reaches the specified position, the telescopic rod 24 fixed at the bottom of the limiting swivel 23 is extended, so that the connecting plate 25 drives the storage component 22 to move downward as a whole. At this time, the storage drum 221 slides out from the bottom of the spiral drum 21, and the slider 223 drives the hollow rod 27 and the connecting frame 28 to move downward as a whole, so that the storage component 22 is in a state where it can directly contact and obtain the soil sample to be collected, ensuring that the subsequent sampling operation can be carried out smoothly. During this process, the rotating rod 26 slides downward along the inner side of the limiting sleeve 7;

[0047] When the limit sleeve 7 is rotated, the limit sleeve 7 drives the rotating rod 26 to rotate together. At this time, the bottom end of the rotating rod 26 drives the threaded sleeve 229 to rotate along the inner side of the limit block 220, so that the threaded rod 228 gradually slides from the threaded sleeve 229. At this time, the threaded rod 228 is driven by the connecting rod 226 to move as a whole with the conical block 227, thereby adjusting the distance between the conical block 227 and the annular block 225, thereby changing the volume of the sampling area. During the sampling process, the amount of soil sample collected each time can be accurately controlled according to the actual geological research objectives, analysis accuracy requirements and other factors, thereby improving the pertinence and effectiveness of sampling and ensuring that the obtained samples are more in line with the requirements of subsequent research.

[0048] When the telescopic cylinder 8 is extended, the mounting plate 94 in the adjusting assembly 9 drives the sliding seat 93 to slide downward along the limiting frame 91. During this process, the limiting wheel 96 rolls in the limiting groove 92 and drives the sliding plate 95 to slide along the surface of the sliding seat 93, forcing the pressing plate 97 to approach the connecting frame 28. As the telescopic cylinder 8 continues to extend, the pressing plate 97 presses on the surface of the connecting frame 28 and presses the connecting frame 28 downward. At this time, the connecting frame 28 drives the hollow rod 27 to move downward. At the same time, the hollow rod 27 presses the annular block 225 downward through the slider 223 and the sliding rod 224, so that the compression spring 222 is compressed. At the same time, the annular block 225, the connecting rod 226 and the conical block 227 slide out from the bottom of the storage tube 221, wherein the conical design of the conical block 227 helps to more smoothly insert it into the surrounding soil to be collected. The resistance encountered during insertion is reduced, and the soil can be attached to the area between the conical block 227 and the annular block 225, so that the soil sample enters the sampling area and the sample collection action is completed. During the whole process, all components cooperate with each other, and the movement of the sampling components is accurately controlled by mechanical transmission and force transmission, ensuring that the soil sample can be successfully obtained.

[0049] When the telescopic cylinder 8 is reset, the conical block 227 and the annular block 225 can return to the storage tube 221 under the elastic force of the compression spring 222, so as to achieve proper storage of the collected soil and prevent the samples from being lost or contaminated during transfer, transportation and subsequent analysis. It is convenient to take out the samples in the storage tube 221 and conduct various tests and research according to the standardized geological analysis process, thus ensuring the integrity of the entire sampling work and the effectiveness of the samples.
