Technical field

The utility model relates to a sampling device, in particular to a rapid sampling device for soil detection.

Background technique

Sand soil refers to soil that is mixed with a large amount of sand and a small amount of clay. It generally refers to soil with a large sand content. The desert area in my country is about 700,000 square kilometers. It is the largest, most widely distributed and most desertified desert in the world. It is one of the countries with serious hazards. During geological exploration or construction, it is necessary to sample the inner soil to detect composition, check moisture content, etc. Common tools for soil sampling, such as Luoyang shovels, are not suitable due to the high fluidity of sandy soil. Specific sampling equipment is required.

For example, the Chinese patent publication number is CN212964118U, a sand and soil sampler, which includes a cylinder, a handle, a round tube, a cover, a guy wire, a wire retaining rib, a wire groove, a cover rotating shaft, and a tying hole; the cylinder It is a hollow thin-walled round tube with a stand and a hollow handle on the upper part; the line blocking rib is located on the outer wall of the round tube; the wire passage groove is located on one side of the line blocking rib; the baffle rotation hole is located at the lower part of the round tube; the cover is a disc shape, there is a capping shaft on it, the axes of the two capping shafts coincide and pass through the center of the capping circle; the capping shaft and the baffle rotating hole are coaxially matched and can be rotated; the pull wire is a thin soft steel wire, and one end is fixedly connected to the bolt On the wire hole, the middle part passes through the wire trough; when in use, adjust the cover to be perpendicular to the section of the cylinder, press it hard into the sand, insert it to a certain depth, turn the handle, and through linkage, the wire pulls the cover to close and block the cylinder. After closing the lid, lift the cylinder to complete sampling. It is simple and convenient to use.

The above-mentioned existing sand and soil sampler has some problems found during use. First, the cover is driven by the pull cord to close and block the lower opening of the barrel, making it impossible to accurately extract sand at a suitable depth. Second, the sand contains a large amount of sand. The pull cord is set In the outside world, inserting the cable into the sand will continuously wear out the cable, and there is a risk of the cable breaking if used for a long time: the third cylinder goes deep into the sand, and a large amount of sand is stored inside the cylinder to block the port, making it difficult for the cover to rotate and close to block it. Problem with the lower mouth of the barrel.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

Please refer to Figures 1-4. The present utility model provides a technical solution: a rapid sampling device for soil detection, including a sampling barrel 1. A threaded discharge port 103 is provided at the lower end of the sampling barrel 1. The threaded discharge port 103 is equipped with a threaded internal thread. Column 201, a conical extrusion head 2 is fixedly installed below the threaded connection column 201, a connecting sleeve 3 is fixedly installed at the upper end of the sampling barrel 1, a limiter 5 is fixedly installed on the connecting sleeve 3 and close to the upper edge, and the connecting sleeve A connecting rod 4 is rotatably installed in the tube 3, and a built-in sleeve 403 is fixedly installed at the lower end of the connecting rod 4. The sampling barrel 1 is provided with a first sampling port 101, and the built-in sleeve 403 is provided with a second sampling port 404.

In this embodiment, by drilling the sampling barrel 1 to a suitable depth, the rotating connecting rod 4 can drive the built-in sleeve 403 to rotate, and the rotation of the built-in sleeve 403 can drive the second sampling port 404 to rotate, connecting the second sampling port 404 with the first After the sampling port 101 is aligned, the fluidity of the sand is used to rotate the connecting sleeve 3 left and right to drive the sampling bucket 1 to rotate. The rotation of the sampling bucket 1 will drive the scraper 102 to rotate, so that the sand slides down the sampling bucket 1 through the first sampling port 101. Inside, rotate the built-in sleeve 403 to stagger the second sampling port 404 and the first sampling port 101. The built-in sleeve 403 can block the first sampling port 101 to prevent sand from entering the inside of the sampling barrel 1 during the upward movement, thereby removing To quickly obtain sand of a specified depth, the conical extrusion head 2 is threadedly installed on the lower end of the sampling barrel 1 through the threaded connecting column 201. The cone-shaped extrusion head 2 can be rotated to separate the sampling barrel 1 and the cone-shaped extrusion head 2 for convenience. Pour the sand sample from the lower end of sampling bucket 1.

Among them, in order to achieve the purpose of sampling sand and soil, this device adopts the following technical solution: a scraper 102 is fixedly installed on the sampling barrel 1 and close to the first sampling port 101, and is connected to the casing 3 and located below the stopper 5 A handle 301 is fixedly installed, a rotating slot 302 is provided on the connecting sleeve 3, and a dialing block 401 is fixedly mounted on the connecting rod 4. The dialing block 401 and the rotating slot 302 cooperate with each other.

When the sampling barrel 1 rotates through the threaded discharge port 103, the sand can be scraped off the inner wall of the hole drilled in the sampling barrel 1, and the fluidity of the sand can be used to slide it into the inside of the sampling barrel 1. The handle 301 is convenient for holding the connecting sleeve 3-way Press down on the sampling barrel 1, and rotate the slot 302 to cooperate with the dialing block 401 so that the dialing block 401 can pass through the sampling barrel 1. At the same time, the dialing block 401 is limited to rotate ninety degrees, driving the connecting rod 4 to rotate, and finally allowing the second sample to be taken. The port 404 is staggered from the first sampling port 101 .

Among them, in order to prevent the connecting rod 4 from rotating, this device adopts the following technical solution: two limiting holes 402 are opened on the connecting rod 4, and a limiting groove 501 is opened in the limiter 5. A limit pin 502 is slidably installed in 501. The limit pin 502 cooperates with the limit hole 402. A spring washer 503 is fixedly installed on the limit pin 502. A return spring 504 is sleeved on the limit pin 502. The limit pin 502 A pull ring 505 is fixedly installed at the end of 502.

The return spring 504 can provide a certain thrust for the spring washer 503. When the spring washer 503 is pushed, it will drive the limit pin 502 to move inside the limit hole 402, thereby limiting the rotation of the connecting rod 4. The pull ring 505 can drive the limit. The latch 502 moves.

The working principle and usage process of the utility model: when using it, the device needs to be placed in a suitable position. The operator holds the handle 301 and presses the device downward, and presses the sampling bucket 1 into the sand. After reaching the appropriate depth, the operator pulls the Ring 505 drives the limit pin 502 to move out of the limit hole 402, releasing the restriction on the connecting rod 4. Turning the dial 401 drives the connecting rod 4 to rotate ninety degrees. The rotation of the connecting rod 4 drives the built-in sleeve 403 to rotate, causing the second The sampling port 404 is aligned with the first sampling port 101, and the connecting sleeve 3 is rotated left and right to drive the sampling barrel 1 to rotate. The rotation of the sampling barrel 1 will drive the scraper 102 to rotate, thereby causing the sand to slide down the inside of the sampling barrel 1 through the first sampling port 101. Then move the dial 401 to reset it, stagger the second sampling port 404 and the first sampling port 101, pull out the sampling bucket 1 and unscrew the conical extrusion head 2, and the sand taken out from the inside of the sampling bucket 1 can be The sample is poured out.

Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art will understand that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the present invention. , substitutions and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
