Technical Field

[0001] The utility model relates to the technical field of soil collection and sampling, in particular to a sampling mechanism used for soil foundation construction quality supervision and detection. Background Art

[0002] Soil quality testing refers to the determination of representative values ​​of factors that affect soil environmental quality to judge environmental quality and its changing trends. What we usually call soil quality testing refers to soil environmental monitoring, which generally includes technical contents such as sampling, sample preparation, analysis methods, result representation, data statistics and quality evaluation. As people's living standards gradually improve, they have quality requirements for the environment in which they live. Therefore, when laying the foundation of a house, soil testing will be carried out on the soil of the foundation to ensure the living environment.

[0003] Current sampling devices generally use a drill rod to drill a sampling head into the soil to collect soil samples. After the soil samples are collected, a lot of mud will adhere to the outside of the drill rod. If the mud is not cleaned in time, the soil attached to the outer wall of the drill rod will become dry and hard, which will not only easily cause pollution and damage to the equipment, but also affect the drilling of the drill rod into the soil during the next sampling. Utility Model Content

A support plate 3 is arranged on the side wall of the bracket 1, and a support sleeve 4 is arranged at the end of the support plate 3 away from the bracket 1. A cleaning cylinder 5 is rotatably arranged on the top of the support sleeve 4, and the cleaning cylinder 5 is sleeved on the outside of the drill rod 2. A gear ring 501 is arranged on the outer wall of the cleaning cylinder 5, and a rotating rod 301 is rotatably arranged on the top of the support plate 3. A gear 6 meshing with the gear ring 501 is arranged on the top of the rotating rod 301. A transmission assembly is also arranged between the drill rod 2 and the support plate 3, wherein the transmission assembly can drive the rotating rod 301 to rotate when the drill rod 2 moves along the axial direction of the cleaning cylinder 5;

[0025] The drill rod 2 is inserted into the soil through the propulsion mechanism, and the soil sample can be collected through the sampling head 201. When the sample is collected, the drill rod 2 is removed from the soil. At this time, more soil will be attached to the outside of the drill rod 2, so the drill rod 2 can be driven to move up and down through the propulsion mechanism, and the rotating rod 301 with the gear 6 can be driven to rotate through the transmission component. The gear 6 will drive the cleaning cylinder 5 with the gear ring 501 to rotate, so that the cleaning cylinder 5 can be moved up and down and rotated along the outer wall of the drill rod 2, so that the soil attached to the outer wall of the drill rod 2 can be scraped off thoroughly, keeping the drill rod 2 clean, and the drill rod 2 can be better penetrated into the soil when sampling next time.

[0026] Among them, the inner wall of the cleaning cylinder 5 is provided with a plurality of staggered horizontal scrapers 502 and vertical scrapers 503; when the cleaning cylinder 5 is attached to the outer wall of the drill rod 2, moves up and down and rotates, the soil on the drill rod 2 is easily scraped off thoroughly by the provided horizontal scrapers 502 and vertical scrapers 503.

[0027] like Figure 2 , Figure 3 and Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the transmission assembly includes two groups of fixed plates 302 arranged at the bottom of the support plate 3, a reel 9 rotatably arranged between the two groups of fixed plates 302, a rotating shaft 8 passing through a group of fixed plates 302 and fixedly connected to the end face of the reel 9, an active bevel gear 801 arranged at the end of the rotating shaft 8 away from the reel 9, a torsion spring 802 serially connected to the rod wall of the rotating shaft 8, a driven bevel gear 7 arranged at the bottom of the rotating rod 301 and meshing with the active bevel gear 801, a connecting plate 202 arranged on the side close to the top of the drill pipe 2, and a pull rope 901 arranged between the connecting plate 202 and the reel 9;

[0028] When the drill rod 2 moves downward, the pull rope 901 will be pulled through the connecting plate 202. At this time, the pull rope 901 will be pulled out of the reel 9 and drive the reel 9 and the rotating shaft 8 to rotate, and the torsion spring 802 will also be twisted. The rotating shaft 8 will drive the rotating rod 301 provided with the driven bevel gear 7 to rotate through the active bevel gear 801, thereby driving the cleaning cylinder 5 to rotate. When the drill rod 2 moves upward, the pull rope 901 will be loosened. At this time, the torsion spring 802 will be released from the force and will drive the reel 9 and the rotating shaft 8 to reverse and reset, thereby driving the cleaning cylinder 5 to rotate in the opposite direction. Therefore, when the drill rod 2 moves up and down, it can drive the cleaning cylinder 5 mounted on the outside thereof to rotate back and forth.

[0029] In addition, a fixing frame 10 is provided on the top of the bracket 1, and a pulley 1001 is rotatably provided on the inner wall of the fixing frame 10. The pull rope 901 passes through the support plate 3 and the bracket 1 and bypasses the rolling groove inside the pulley 1001; when the drill rod 2 pulls the pull rope 901, the pull rope 901 will roll along the pulley 1001, so that the pull rope 901 can be pulled conveniently to avoid excessive friction on the pull rope 901 and thus wear and breakage.

[0034] The propulsion mechanism includes a cylinder 11 arranged at the top of the bracket 1, a piston rod 12 arranged at the output end of the cylinder 11, and a threaded head 1201 arranged at the bottom of the piston rod 12. A threaded hole matching the threaded head 1201 is provided on the top of the drill rod 2. When the cylinder 11 is started, the drill rod 2 can be driven to move down and penetrate into the soil for soil sample collection through the piston rod 12, and the drill rod 2 can be disassembled through the threaded head 1201, which is convenient for maintenance and replacement of the drill rod 2. The height of the entire bracket 1 can also be adjusted by pulling out the U-shaped plate 102 to slide inside the support frame 101, and the bracket 1 with adjusted height can be fixed by passing the bolt 103 through the support frame 101 and screwing it into the positioning groove 1021, so that the drill rod 2 can be inserted into the soil at different depths for sampling as needed.

[0035] The working principle of the utility model is as follows: starting the cylinder 11 can drive the drill rod 2 to penetrate into the soil, and then the soil sample can be collected through the sampling head 201. When the sample is collected, the drill rod 2 is moved out of the soil. At this time, more soil will be attached to the outside of the drill rod 2, so the drill rod 2 can be driven to move up and down by the cylinder 11, and the pull rope 901 can drive the reel 9 and the rotating shaft 8 to rotate back and forth, and the rotating rod 301 can drive the cleaning cylinder 5 provided with a gear ring 501 to rotate through the gear 6, so that the cleaning cylinder 5 can be moved up and down and rotated along the outer wall of the drill rod 2, so that the soil attached to the outer wall of the drill rod 2 can be scraped off thoroughly, the drill rod 2 can be kept clean, and the drill rod 2 can be better penetrated into the soil when sampling next time.
