Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a sampling component for soil detection in environmental protection projects. Background Art

[0002] In environmental protection projects, soil testing is an important part of assessing soil environmental quality, identifying pollution risks, formulating remediation plans, and monitoring remediation effects.

[0003] The soil detection sampling assembly currently in use mainly includes a frame, a handle, a sampling rod, a tubular sampling head, a motor, a battery and a controller. The handle and the frame can be used to move the entire assembly vertically. The electrically connected motor and battery can be driven by the controller according to the user's operation, so that the sampling rod drives the tubular sampling head at the bottom to rotate. After the tubular sampling head cuts the soil, the soil can be stored in the tubular sampling head, taken out along with the tubular sampling head, and transferred to the sampler for sealed storage.

[0004] Since soil sampling in environmental protection projects requires soil samples at different depths, sampling rods need to be docked before repeated sampling operations to increase the sampling depth. However, in the existing technology, the docking of sampling rods is often completed by bolt group connection. The operation is cumbersome, and the docking and disassembly take a long time, which affects work efficiency.

[0005] Therefore, in order to solve the above problems, a sampling assembly for soil detection in environmental protection engineering is proposed. Utility Model Content

[0006] The purpose of the present utility model is to provide a sampling assembly for soil detection in environmental protection projects, which can more conveniently change the sampling depth, thereby solving the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a sampling assembly for soil testing in environmental protection projects, comprising an equipment box, handles fixedly installed on both sides of the equipment box, a sleeve rotatably installed on the inner bottom of the equipment box through a bearing seat, a linear bearing fixedly installed on the top of the equipment box, a sampling rod passed through the interior of the sleeve and the linear bearing, a tubular sampling head was installed at the lower end of the sampling rod, and a plurality of pairs of rectangular grooves were opened on the sampling rod along the axial direction; a docking assembly for engaging one of the pairs of rectangular grooves was installed on the sleeve, a driving assembly for rotating the sleeve was installed on one side of the interior of the equipment box, a battery module was fixedly installed on the other side of the interior of the equipment box, and a controller was embedded on the front side of the equipment box.

[0008] Specifically, the docking assembly includes a rectangular block, a spring and a rectangular box. The tube sleeve is fixedly installed with a pair of rectangular boxes. The tube sleeve is provided with a through-hole aligned with the rectangular boxes. A spring is fixedly installed between the rectangular box and the rectangular block. The end of the rectangular block away from the spring passes through the through-hole and is plugged into the rectangular groove for assembly.

[0009] Furthermore, the docking assembly also includes a wedge-shaped groove and a shift ring. The tube sleeve is provided with a shift ring. The bottom of the rectangular block is provided with a wedge-shaped groove. When the shift ring is inserted into the wedge-shaped groove, the rectangular block is separated from the rectangular groove.

[0010] Specifically, a push-pull electromagnet is fixedly installed on the front side of the interior of the equipment box, and the push-pull end of the push-pull electromagnet is fixedly assembled with a dial ring through a connecting plate.

[0011] Specifically, the circumferential side surface of the sampling rod is provided with an identification band corresponding to each pair of rectangular grooves.

[0012] Specifically, the drive assembly includes a motor, a synchronous belt and a synchronous wheel. The motor is fixedly assembled with the equipment box. The output end of the motor and the circumferential side of the sleeve are fixedly installed with synchronous wheels. A synchronous belt is installed between the synchronous wheels.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] Adapt to soil sampling needs at different depths: The docking assembly installed on the sleeve can be connected to the rectangular slots at different positions on the sampling rod, thereby adjusting the distance between the tubular sampling head and the equipment box and changing the sampling depth of the tubular sampling head. This design allows operators to gradually adjust the sampling depth according to actual needs, improving the flexibility and accuracy of sampling.

[0015] Stable and reliable torque transmission: the rectangular block and the rectangular groove in the docking assembly are plugged into and assembled, and the spring gives the two rectangular blocks the force to move towards each other, ensuring the firmness of the connection between the rectangular block and the rectangular groove, thereby ensuring the torque transmission from the sleeve to the sampling rod; at the same time, the docking assembly also includes a wedge-shaped groove and a dial ring. The dial ring is driven to move by a push-pull electromagnet, which can realize the rapid separation and reset of the rectangular block and the rectangular groove. This design not only ensures the stability of torque transmission, but also facilitates the adjustment of the axial position of the sampling rod, making the operation of changing the sampling depth more time-saving and convenient, thereby achieving the purpose of improving work efficiency.

DETAILED DESCRIPTION

[0021] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 The utility model provides a technical solution: a sampling assembly for soil detection in environmental protection projects, including an equipment box 9, which is a rectangular box structure and is used to provide an installation base for other components; handles 1 are fixedly installed on both sides of the equipment box 9, and the lifting height of the equipment box 9 can be adjusted by the handles 1.

[0023] A sleeve 4 is rotatably mounted on the inner bottom of the equipment box 9 through a bearing seat 3, so that the sleeve 4 can rotate circumferentially. A linear bearing 7 is fixedly mounted on the top of the equipment box 9. A sampling rod 8 is passed through the interior of the sleeve 4 and the linear bearing 7. The bearing seat 3 is an existing component composed of a seat body and bearings. The linear bearing 7 allows the sampling rod 8 to rotate circumferentially and translate axially inside. A tubular sampling head 13 is mounted on the lower end of the sampling rod 8 by means of a bolt group connection to facilitate replacement of the tubular sampling head 13. The sampling rod 8 is provided with several pairs of rectangular grooves 12 along the axial direction.

[0024] The tubular sampling head 13 is made of metal (such as stainless steel) and has a hollow tubular structure with a smooth inner wall for easy soil entry. The lower end of the sampling head has serrations distributed in a circumference to facilitate cutting into the soil.

[0025] See also Figure 2The sleeve 4 is equipped with a docking assembly 5 for clamping one of the pairs of rectangular grooves 12. The docking assembly 5 can be clamped with the rectangular grooves 12 at different positions, thereby adjusting the distance between the tubular sampling head 13 and the equipment box 9 to adapt to the needs of soil sampling at different depths; a driving assembly 2 for rotating the sleeve 4 is installed on one side of the interior of the equipment box 9. The driving assembly 2 is used to rotate the sleeve 4 circumferentially, and the sampling rod 8 can be driven by clamping the docking assembly 5 with the rectangular grooves 12.

[0026] The sampling rod 8 is made of high-strength metal material (such as carbon steel) to ensure strength in use.

[0027] A battery module 6 (lithium battery) is fixedly installed on the other side of the interior of the equipment box 9, and a controller 14 is embedded on the front side of the equipment box 9. The embedded joint is sealed with a sealing strip to effectively prevent dust, moisture and other external impurities from entering the interior of the equipment box 9; the electrical components are electrically connected to the battery module 6 through the controller 14, and the controller 14 integrates a power management circuit and a signal processing module. It can receive the electrical energy provided by the battery module 6 and reasonably distribute it to each electrical component, while regulating the working status of each component; the controller 14 has buttons corresponding to specific function instructions. The operator only needs to press the corresponding button, and the controller 14 can respond quickly and accurately transmit the instruction signal to the corresponding electrical component, thereby realizing convenient control of various functions of the device. This part of the electrical control structure is a prior art and will not be described in detail.

[0028] To meet the sampling depth requirement, there are at least two pairs of rectangular slots 12, and the distance between two adjacent pairs of rectangular slots 12 is 1 meter.

[0029] See also Figure 3 The docking assembly 5 includes a rectangular block 51, a spring 52 and a rectangular box 53. A pair of rectangular boxes 53 are fixedly installed on the cylinder sleeve 4. The cylinder sleeve 4 is provided with a through-hole aligned with the rectangular box 53. A spring 52 is fixedly installed between the rectangular box 53 and the rectangular block 51. The end of the rectangular block 51 away from the spring 52 passes through the through-hole and is plugged into the rectangular groove 12 for assembly; the rectangular block 51 can slide in the through-hole, and the spring 52 makes the two rectangular blocks 51 have a force to move closer to each other, ensuring the firmness of the rectangular block 51 when plugged into the rectangular groove 12, thereby ensuring the torque transmission from the cylinder sleeve 4 to the sampling rod 8.

[0030] The docking assembly 5 also includes a wedge-shaped groove 54 and a shift ring 55. The cylinder sleeve 4 is provided with the shift ring 55. The bottom of the rectangular block 51 is provided with a wedge-shaped groove 54. The wedge-shaped groove 54 has an inclined surface. The distance between the upper ends of the two inclined surfaces is smaller than the distance between the lower ends of the two inclined surfaces. When the shift ring 55 is inserted upward into the wedge-shaped groove 54, it pushes the rectangular block 51 away from each other along the pair of inclined surfaces, so that the rectangular block 51 is separated from the rectangular groove 12. After the shift ring 55 is moved downward out of the wedge-shaped groove 54, the rectangular block 51 will be reset due to the elastic force of the spring 52.

[0031] In addition, the bottom of the rectangular box 53 is open, which does not affect the insertion of the ring 55 and the wedge-shaped groove 54. The cross-section of the ring 55 is circular to improve the smoothness of the insertion with the wedge-shaped groove 54.

[0032] See also Figure 4 A push-pull electromagnet 10 is fixedly installed on the front side of the interior of the equipment box 9, and the push-pull end of the push-pull electromagnet 10 is fixedly assembled with the dial ring 55 through the connecting plate; the push-pull electromagnet 10 has two working states: downward reset and upward adsorption and retraction, which can drive the dial ring 55 to move to the upper and lower positions, making the plugging and separation actions of the dial ring 55 and the wedge-shaped groove 54 more accurate and faster.

[0033] See also Figure 1 The circumferential side surface of the sampling rod 8 is provided with an identification band 11 corresponding to each pair of rectangular grooves 12, that is, when each identification band 11 is aligned with the upper end surface of the linear bearing 7, the corresponding pair of rectangular grooves 12 on the lower side can align with the two rectangular blocks 51.

[0034] See also Figure 2 The drive assembly 2 includes a motor 21, a synchronous belt 22 and a synchronous wheel 23. The motor 21 is fixedly assembled with the equipment box 9. The output end of the motor 21 and the circumferential side of the cylinder sleeve 4 are fixedly installed with a synchronous wheel 23, and a synchronous belt 22 is sleeved between the synchronous wheels 23; the diameter of the synchronous wheel 23 on the motor 21 is smaller than the diameter of the synchronous wheel 23 on the cylinder sleeve 4, which plays the role of reducing speed and increasing torque. When the motor 21 is working, the cylinder sleeve 4 can be rotated through the transmission of the synchronous belt 22 and the synchronous wheel 23.

[0035] The driving component 2 can also adopt a transmission mode of chain and sprocket, or a transmission mode of two gears meshing with each other, and can be adapted for use according to the soil sampling environment. It only needs to achieve matching power transmission without affecting the implementation of this embodiment.

[0036] The working principle of this embodiment is as follows:

[0037] During use, the controller 14 first controls the push-pull electromagnet 10 to pull the dial ring 55 upward, so that the dial ring 55 is plugged into the wedge-shaped groove 54 and the rectangular block 51 is separated from the rectangular groove 12. At this time, the sampling rod 8 can be axially adjusted inside the sleeve 4 and the linear bearing 7.

[0038] First, align the bottommost identification band 11 with the upper end surface of the linear bearing 7. At this time, the pair of rectangular grooves 12 on the lower side are aligned with the rectangular block 51. The controller 14 controls the push-pull electromagnet 10 to reset the dial ring 55 downward, so that the dial ring 55 is separated from the wedge-shaped groove 54, and the rectangular block 51 is reconnected with the rectangular groove 12 due to the elastic force. Even if the pair of rectangular grooves 12 are not completely aligned with the rectangular block 51 and there is a circumferential misalignment, the rectangular block 51 will also abut against the circumferential side of the sampling rod 8. Manual circumferential rotation of the sampling rod 8 can ensure that the pair of rectangular grooves 12 can be connected with the rectangular block 51.

[0039] After completion, hold the handle 1 vertically and then rotate the sampling rod 8 and the tubular sampling head 13 through the drive assembly 2 until the tubular sampling head 13 is inserted into the soil to a specified depth. The soil will be retained in the tubular sampling head 13. Lift the device to complete the sampling operation.

[0040] Repeat the above operation, adjust the next marking belt 11 from bottom to top to align it with the upper end surface of the linear bearing 7, and gradually adjust the distance between the tubular sampling head 13 and the equipment box 9, thereby adjusting the digging depth of the soil sampling.
