3results about How to "Improve sampling productivity" patented technology

The utility model discloses a soil sampling device for agricultural technology popularization, and belongs to the technical field of soil sampling. Comprising a sampling barrel; the driving shaft is used for driving the sampling barrel to drill into soil, and one end of the driving shaft is detachably connected with the sampling barrel; the bearing plate is rotationally arranged at the other end of the driving shaft and used for supporting a power source of the driving shaft; the cleaning assembly is arranged in the sampling barrel and is driven by external force to move in the sampling barrel; the driving shaft is adopted to drive the sampling barrel to drill into the soil for sampling, the cleaning assembly is located in the sampling barrel and does not interfere with the sampling process in the sampling process, and after sampling is completed, the cleaning assembly can clean the interior of the sampling barrel, so that the problem that the sampling barrel is complex in internal structure and cannot be used for sampling is effectively solved. The sampling device solves the problems that the internal cleaning operation is troublesome and the working efficiency of a sampling site is reduced in the prior art, and further realizes the effect of quickly cleaning the residual soil on the inner wall of the sampling barrel in the sampling process.

This utility model relates to the field of toxic gas sampling technology, and is an online closed sampling device for toxic gases. It includes a transparent box, a box support, an air inlet assembly, and protective gloves. The box support is located at the bottom of the transparent box. The air inlet assembly includes a first straight pipe section, a second straight pipe section, an air inlet hose, and a gas connection hose. An air inlet hole is provided on the top wall of the transparent box. The first straight pipe section extends from the outside of the transparent box through the air inlet hole into the interior of the transparent box. A hand valve is fixedly installed on the second straight pipe section. The front wall of the transparent box is designed with symmetrical double doors, including a left door and a right door. The left and right doors each have symmetrical left and right hand holes, and protective gloves are fixedly installed in both the left and right hand holes to reach into the transparent box. This utility model has a reasonable and compact structure, is easy to use, and improves both the safety and efficiency of online toxic gas sampling.

This utility model relates to the field of road engineering technology and discloses a sampling device for roadbed testing, including a base plate. A support plate is fixedly connected to the top of the base plate, and a driving assembly is fixedly connected to the front side of the support plate. A connecting plate is fixedly connected to the driving end of the driving assembly, and an auger rod is slidably connected to the bottom end of the connecting plate. Fixed rods are slidably connected to the inside of both sides of the connecting plate. A threaded block is threadedly connected to one side of the inside of each fixed rod, and an arc-shaped sliding rod is rotatably connected to the adjacent sides of the two threaded blocks. A spring is sleeved on the outside of the arc-shaped sliding rod, and a limit plate is rotatably connected to the outside of the arc-shaped sliding rod. A receiving hole is opened inside the fixed rod. In this utility model, there is no need for tedious searching, using tools, and repeated twisting operations, which greatly saves labor and time costs, thereby improving the overall sampling efficiency.
