Description

Technical Field

[0001] This utility model belongs to the field of soil sampling technology, and in particular relates to a soil sampling drill. Background Technology

[0002] Soil sampling is of great significance in agriculture, environmental monitoring, geological exploration, and other fields. To ensure the accuracy of test results, it is necessary to obtain representative and effective soil samples quickly and efficiently. When using a soil sampling auger, if hard soil is encountered, a hammer is typically used to strike the top of the auger, applying pressure to the drill bit to insert it into the soil for sampling. After removing the drill bit from the soil, the soil in the storage chamber is expelled by vibration or tapping, thus completing the sampling process.

[0003] Based on research and long-term experience in actual soil exploration and sampling, it was found that existing soil sampling burrs have several drawbacks. Firstly, the need for hammering during sampling is physically demanding and requires carrying a variety of tools, making it inconvenient for fieldwork and hindering the efficiency and progress of field sampling. Secondly, existing burrs require at least two people to operate, resulting in high costs, personnel redundancy, and low efficiency. Therefore, there is an urgent need to improve existing soil sampling burrs and provide a new type of soil sampling burr. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a soil sampling drill that is reasonably designed, simple in structure, easy to operate, time-saving, labor-saving, and convenient for sample discharge, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A soil sampling drill includes a support frame, a manual hydraulic jack, and a sampling tube. A base plate is fixed to the bottom of the support frame, and a groove is formed in the middle of the front end of the base plate. The manual hydraulic jack is fixedly installed at the middle of the top of the support frame, and a docking seat is fixedly connected to the telescopic end of the manual hydraulic jack. Symmetrical through grooves are formed on the left and right outer walls of the docking seat. The sampling tube is composed of a first half-tube and a second half-tube. A positioning component is fixed to the top of the sampling tube, and the positioning component and the docking seat form a snap-fit ​​disassembly structure. A flushing head is fixedly installed at the bottom of the first half-tube, and a scale mark is provided on the outer wall of the front end of the first half-tube. Handles are fixedly installed on opposite sides of the tops of both the first and second half-tubes.

[0007] In a preferred embodiment, the first half-tube and the second half-tube are detachably connected. A snap-fit ​​groove is provided on the inner wall of the bottom right end of the first half-tube, and a protrusion is fixed at the bottom end of the second half-tube.

[0008] In a preferred embodiment, both the snap-fit ​​groove and the protrusion are semi-circular and their dimensions are compatible with each other. The protrusion is engaged with the first half-tube through the snap-fit ​​groove.

[0009] In a preferred embodiment, the positioning component includes a semi-cylinder, a groove, a movable locking block, and a spring. The two semi-cylinders are respectively fixed to the top of the first half-tube and the second half-tube. A groove is provided inside the semi-cylinder, and a movable locking block is slidably engaged in the groove. A spring is fixedly connected between one end of the movable locking block located in the groove and the semi-cylinder.

[0010] In a preferred embodiment, the diameter of the semi-cylinder is equal to the inner diameter of the docking seat, the movable block is formed by a spring to form an elastic structure, the movable block is located above one end outside the slide groove in an inclined shape, and the movable block is engaged with the docking seat through the through groove.

[0011] In a preferred embodiment, the thickness of the flushing head decreases in the direction away from the sampling tube, and the inner diameters of the flushing head and the sampling tube are equal.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In the solution of this utility model:

[0014] In this device, by controlling the manual hydraulic jack to gradually extend, downward pressure can be applied to the docking seat, positioning component and sampling tube. The soil-following head with decreasing thickness from top to bottom can effectively reduce soil resistance, making it easier to insert the sampling tube into the soil for sampling. Compared with the existing technology, this process does not require carrying or using many tools. The device has a simple structure, is easy to carry, and can be operated by a single person, saving time and effort and increasing work efficiency.

[0015] The sampling tube consists of a first half-tube and a second half-tube that are interlocked. During sampling, the scale markings on the outer wall of the first half-tube make it easy to observe the depth of insertion into the soil. After sampling, the movable locking block can be pressed to retract and release the locking block, allowing the sampling tube to be removed. Then, the second half-tube can be pushed upward relative to the first half-tube to disengage the protrusion from the locking groove, thus separating the first and second half-tubes. This allows for a more effortless, convenient, and complete discharge of the soil sample. Not only is the soil sample discharged more thoroughly, but the sampling tube is also easier to clean, preventing soil residue and avoiding interference between soil samples taken multiple times, thus facilitating the acquisition of accurate test data.

[0024] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0025] like Figure 1-5 As shown, the soil sampling drill of this utility model includes a support frame 1, a manual hydraulic jack 4, and a sampling tube. A base plate 2 is fixed to the bottom end of the support frame 1. A groove 3 is opened in the middle of the front end of the base plate 2. The manual hydraulic jack 4 is fixedly installed in the middle of the top end of the support frame 1. A docking seat 5 is fixedly connected to the telescopic end of the manual hydraulic jack 4. Through grooves 6 are symmetrically opened on the outer walls of the left and right sides of the docking seat 5. The sampling tube is composed of a first half tube 7 and a second half tube 8. A positioning component 9 is fixed to the top end of the sampling tube. The positioning component 9 and the docking seat 5 form a snap-fit ​​disassembly structure. A soil flushing head 11 is fixedly installed at the bottom end of the first half tube 7. A scale mark 12 is provided on the outer wall of the front end of the first half tube 7. A handle 14 is fixedly installed on the opposite side of the top of the first half tube 7 and the second half tube 8.

[0026] Based on the above structure, the first half-tube 7 and the second half-tube 8 are detachably connected. A snap-fit ​​groove 13 is provided on the inner wall of the bottom right end of the first half-tube 7, and a protrusion 10 is fixed at the bottom end of the second half-tube 8.

[0027] Based on the above structure, both the snap-fit ​​groove 13 and the protrusion 10 are semi-circular and their dimensions are compatible with each other. The protrusion 10 is engaged and connected to the first half tube 7 through the snap-fit ​​groove 13.

[0028] In this embodiment, the protrusions 10 and the snap-fit ​​grooves 13 with matching sizes facilitate the snap-fit ​​splicing between the first half-pipe 7 and the second half-pipe 8, which is convenient for subsequent soil sampling.

[0029] Based on the above structure, the positioning component 9 includes a semi-cylinder 91, a slide groove 92, a movable locking block 93, and a spring 94. The two semi-cylinders 91 are respectively fixed to the top of the first half-tube 7 and the second half-tube 8. The slide groove 92 is opened inside the semi-cylinder 91. The movable locking block 93 is engaged and slidably arranged in the slide groove 92. The spring 94 is fixedly connected between the end of the movable locking block 93 located in the slide groove 92 and the semi-cylinder 91.

[0030] Based on the above structure, the diameter of the semi-cylinder 91 is equal to the inner diameter of the docking seat 5. The movable block 93 forms an elastic structure through the spring 94. The movable block 93 is located above one end outside the slide groove 92 in an inclined position. The movable block 93 is engaged with the docking seat 5 through the through groove 6.

[0031] In this embodiment, after the first half-tube 7 and the second half-tube 8 are snapped together to form a sampling tube, the two semi-cylinders 91 at the top of the sampling tube can be inserted into the docking seat 5, and the two movable locking blocks 93 can be stably locked into the two through slots 6 by the spring 94, which facilitates the installation and use of the sampling tube, and also facilitates the disassembly of the sampling tube.

[0032] Based on the above structure, the thickness of the flushing head 11 is set to decrease in the direction away from the sampling tube, and the inner diameter lengths of the flushing head 11 and the sampling tube are equal.

[0033] In this embodiment, the soil flushing head 11, whose thickness decreases from top to bottom, can effectively reduce soil resistance and facilitate the insertion of the sampling tube into the soil for sampling operations.

[0034] The working principle of this utility model is as follows:

[0035] When using it, firstly as follows Figure 2As shown, the second half-tube 8 is first misaligned and tightly attached to the right side of the first half-tube 7. Then, the second half-tube 8 is manually pushed vertically downward relative to the first half-tube 7, so that the protrusion 10 at the bottom of the second half-tube 8 can be inserted into the snap-fit ​​groove 13. The first half-tube 7 and the second half-tube 8 are initially positioned and combined to form a sampling tube. Then, the semi-cylinder 91 at the top of the first half-tube 7 and the second half-tube 8 is inserted into the docking seat 5. At this time, the inclined surface of the movable snap-fit ​​block 93 is compressed and retracted. Then, it can be popped out and reset by the spring 94 and engaged with the docking seat 5 through the through groove 6 to complete the stable installation of the sampling tube.

[0036] Place the device at the designated sampling location and control the manual hydraulic jack 4 to gradually extend, which will apply downward pressure to the docking seat 5, positioning component 9 and sampling tube. The soil-flush head 11, whose thickness decreases from top to bottom, can effectively reduce soil resistance, making it easier to insert the sampling tube into the soil for sampling. The scale markings 12 on the outer wall of the first half-tube 7 make it easy to observe the depth of insertion into the soil at any time.

[0037] Compared with existing technologies, this device does not require carrying or using many tools during the sampling process. The device has a simple structure, is easy to carry, and can be operated by a single person, saving time and effort and increasing work efficiency. After sampling, the sampling tube can be removed and split into the first half tube 7 and the second half tube 8, which can discharge the soil sample more easily, conveniently, and completely. Not only is the soil sample discharged more fully, but the sampling tube is also easy to clean, preventing soil residue and avoiding mutual interference between soil samples when sampling multiple times, which facilitates the acquisition of accurate test data.

[0038] It should be noted that the manual hydraulic jack 4 is an existing device on the market, and its specific structure and working principle are mature existing technologies, so it will not be described in detail.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
