Description

Technical Field

[0001] This utility model belongs to the field of geological sampling technology, specifically relating to a mobile sampling device for measurement. Background Technology

[0002] In fields such as environmental monitoring, geological exploration, and construction engineering, on-site sampling is a crucial step in obtaining firsthand data. Mobile sampling devices are widely used in these fields due to their flexibility and convenience. However, traditional mobile sampling devices face a significant technical challenge in practical use: the drilling process generates substantial amounts of dust. This dust not only affects the health and safety of operators but also pollutes the surrounding environment and can even interfere with the accuracy of the sampling data.

[0003] Currently, mobile sampling devices on the market mainly suffer from the following technical defects:

[0004] Dust control is ineffective: Traditional devices often use simple dust covers or water spraying for dust suppression. Dust covers can only block some large dust particles and are almost ineffective against fine particles; although water spraying is more effective, it changes the humidity of the sample, affecting subsequent test results, and is difficult to implement in areas with scarce water resources.

[0005] Low integration of dust removal systems: Existing devices often have dust removal systems separate from the sampling system, resulting in bulky equipment that is difficult to move. Although some devices integrate dust removal functions, their dust removal efficiency is low, and they cannot effectively collect the fine dust generated during drilling.

[0006] Therefore, there is an urgent need to develop a new type of mobile sampling device that can effectively suppress dust generated during drilling while ensuring sampling quality, and also take into account portability and ease of operation. Utility Model Content

[0007] To address the above problems, the purpose of this utility model is to provide a mobile sampling device that solves the problems of poor dust control, low dust removal efficiency, and inconvenient operation of existing mobile sampling devices during drilling sampling.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a mobile sampling device for measurement, comprising a frame, wheels mounted on the bottom of the frame, a controller, a handrail, a column, and a dust removal assembly mounted on the frame, a rack mounted on the column, the rack engaging with a gear mechanism, the gear mechanism mounted on a lifting seat, the lifting seat slidably mounted on the column, a sampling motor mounted inside the lifting seat, the output shaft of the sampling motor connected to one end of a sampling cylinder, the dust removal assembly comprising an outer tube, the outer tube being inserted through the frame, the side of the outer tube communicating with the side of an outer shell, one end of the outer shell being threadedly connected to an internal threaded cap, a filter cartridge sandwiched between the internal threaded cap and the outer tube, and the other end of the outer shell being fitted with an exhaust fan and having a through hole corresponding to the exhaust fan's duct.

[0009] The beneficial effects of this utility model are as follows: when the sampling cylinder moves down and rotates to drill and sample, the dust generated during the drilling process is effectively adsorbed into the inner side of the outer shell and effectively isolated and collected by the filter cylinder.

[0010] To further improve the dust collection effect of the dust removal components;

[0011] As a further improvement to the above technical solution: the top end of the outer tube is connected to an end plate, and the bottom surface of the end plate is fitted with an inner tube. The inner tube, the outer tube, and the sampling cylinder are collinear, and an annular channel structure is formed between the inner tube and the outer tube.

[0012] The beneficial effects of this improvement are: the annular channel formed between the outer and inner tubes can effectively improve the efficiency of dust collection.

[0013] To further improve the dust collection efficiency of the dust removal components;

[0014] As a further improvement to the above technical solution: the bottom end of the inner tube is located above the bottom end of the outer tube, and the height difference between the bottom ends of the inner tube and the outer tube is not less than 1 cm.

[0015] The beneficial effects of this improvement are: the dust generated during the drilling and sampling process can enter the interior of the outer and inner tubes from the lower side, which increases the air intake area and improves the dust collection effect compared to the vertical upward air intake channel design.

[0016] In order to effectively isolate and filter the collected dust through the use of filter cartridges;

[0017] As a further improvement to the above technical solution: the diameter of the air duct of the exhaust fan is not greater than the inner diameter of the filter cartridge, and the two ends of the filter cartridge are bonded with annular rubber sealing gasket structures.

[0018] The beneficial effect of this improvement is that the filter cartridge can effectively isolate and filter the collected dust.

[0019] To ensure the lifting platform moves stably up and down on the column;

[0020] As a further improvement to the above technical solution: a sleeve is installed in the lifting seat, the sleeve passes through the upper and lower ends of the lifting seat, and the sleeve is slidably fitted on the outside of the column.

[0021] The beneficial effect of this improvement is that, under the limitation of the sleeve, the lifting seat can move stably on the column.

[0022] In order to drive the lifting seat to move stably up and down by using a gear mechanism;

[0023] As a further improvement to the above technical solution: the gear mechanism includes a gear, which is rotatably mounted on a sleeve. A worm gear is mounted on the shaft of the gear, and a worm is meshed with the worm. The worm is rotatably mounted on a lifting seat, and a handwheel is mounted on one end of the worm.

[0024] The beneficial effect of this improvement is that the lifting seat can be driven to move stably up and down on the column through the worm gear pair mechanism and the gear rack mechanism.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0032] Example 1:

[0033] like Figure 1As shown in Figure 4: A mobile sampling device includes a frame 1, with wheels 2 mounted on the bottom of the frame 1. A controller 3, a handrail 4, a column 5, and a dust removal assembly 6 are mounted on the frame 1. A rack 7 is mounted on the column 5, and the rack 7 meshes with a gear mechanism 9. The gear mechanism 9 is mounted on a lifting seat 8, which is slidably mounted on the column 5. A sampling motor 10 is installed inside the lifting seat 8, and the output shaft of the sampling motor 10 is connected to one end of a sampling cylinder 11. The dust removal assembly 6 includes an outer tube 61, which is inserted through the frame 1. The side of the outer tube 61 is connected to the side of the outer shell 64. On one side, an inner threaded cap 65 is threaded to one end of the outer shell 64. A filter cartridge 66 is sandwiched between the inner threaded cap 65 and the outer tube 61. An exhaust fan 67 is installed at the other end of the outer shell 64, and a through hole is opened opposite to the air duct of the exhaust fan 67. When the sampling cylinder 11 moves down and rotates to drill and sample, the dust generated during the drilling process is effectively adsorbed into the inner side of the outer shell 64 and effectively isolated and collected by the filter cartridge 66. An end plate 63 is connected to the top of the outer tube 61, and an inner tube 62 is installed on the bottom surface of the end plate 63. The axes of the inner tube 62, the outer tube 61, and the sampling cylinder 11 are collinear, and the inner tube 62 and the outer tube 61 are aligned. The filter cartridge 66 has an annular channel structure formed between the outer tube 61 and the inner tube 62, which can effectively improve the dust collection efficiency. The bottom end of the inner tube 62 is located above the bottom end of the outer tube 61, and the height difference between the bottom ends of the inner tube 62 and the outer tube 61 is not less than 1 cm. Dust generated during drilling and sampling can enter the interior of the outer tube 61 and the inner tube 62 from the lower side. Compared with the vertical upward air inlet channel design, the air inlet area is increased and the dust collection effect is improved. The diameter of the air duct of the exhaust fan 67 is not greater than the inner diameter of the filter cartridge 66. The two ends of the filter cartridge 66 are bonded with annular rubber sealing gaskets, which can effectively isolate the filter cartridge. The lifting seat 8 is equipped with a sleeve 81 to filter and collect dust. The sleeve 81 extends through both the upper and lower ends of the lifting seat 8 and is slidably fitted onto the outside of the column 5. Under the limitation of the sleeve 81, the lifting seat 8 can move stably on the column 5. The gear mechanism 9 includes a gear 91, which is rotatably mounted on the sleeve 81. A worm gear 92 is mounted on the shaft of the gear 91. The worm gear 92 is meshed with a worm 93. The worm 93 is rotatably mounted on the lifting seat 8 and a handwheel 94 is mounted on one end of the worm 93. The lifting seat 8 can be driven to move stably up and down on the column 5 through the worm gear pair mechanism and the gear and rack mechanism.

[0034] The working principle of this technical solution is as follows: Start the sampling motor 10, turn the handwheel 94 to drive the worm gear 93 to rotate, the worm gear drives the worm wheel 92 and gear 91 to rotate, the gear meshes with the rack 7, causing the lifting seat 8 to move up and down along the column 5: Turn the handwheel clockwise: the gear and rack drive causes the lifting seat to descend, and the sampling cylinder 11 approaches the ground; Turn the handwheel counterclockwise: the lifting seat rises and moves away from the ground; Through the sliding fit between the sleeve 81 and the column 5, the lifting process is ensured to be smooth. When the bottom of the sampling cylinder is about 5cm from the ground, stop turning the handwheel. The worm gear pair self-locks to prevent the lifting seat from sliding. During the drilling process, the exhaust fan 67 starts simultaneously, forming a negative pressure in the annular channel, which sucks in the dust generated during drilling from the side and below, filters it through the filter cartridge 66, and the clean air is discharged from the exhaust fan outlet.
