4results about How to "Convenient sampling operation" patented technology

This invention relates to the field of hydrogeology, specifically to a groundwater sampling device for hydrogeology. The device comprises multiple vertically arranged splicing rods, each with a threaded hole at its top and a screw head fixedly connected to its bottom. The screw head engages with the adjacent threaded hole. A circular hole is formed on the top surface of a sleeve plate, which slidably engages with the outer wall of the splicing rod. A motor box is located on one side of the sleeve plate. In this invention, the splicing rods are sequentially spliced ​​and inserted into a well. A welded metal bracket secures the splicing rods to the wellhead. The sleeve plate is lowered to the aquifer using an automatic winch. An electric push rod moves the sampling mechanism, allowing it to drill into the aquifer through the well pipe's filter holes. The sampling mechanism then samples the water flow within the aquifer, improving the accuracy of sampling a single aquifer. After sampling, a filling mechanism can backfill the aquifer with soil, facilitating sampling operations for users.

This invention discloses a base sampling device for road construction, including a movable base, casters, a lifting mechanism, a sampling mechanism, a sampling hole, a through hole, a turntable, a motor, a placement groove, and an installation groove. This invention features a reasonable and simple structure, low production cost, and convenient installation. Starting the motor rotates the entire turntable, allowing the empty placement groove to be positioned directly below the sampling cylinder, facilitating sample collection and placement. The extension of the cylinder causes the movable hole seat to move downwards, which in turn drives the connecting shaft downwards via a connecting block. This downward movement of the connecting shaft then pushes the sample into the placement groove via a push-out block, improving sample retrieval convenience. Starting the motor rotates the turntable, allowing the through hole to be positioned directly below the sampling mechanism, facilitating sampling at the next location.

The utility model discloses a sample collection device for animal husbandry veterinary examination, which comprises a mounting frame, and supporting mechanisms are arranged on two sides of the mounting frame in a mirroring manner. The two ends of the U-shaped frame are horizontally arranged on one side of the bottom of the mounting frame in a sliding and penetrating mode, the inclined baffle is hinged to one side of the top of the mounting frame, the supporting rods are hinged between the U-shaped frame and the inclined baffle, the number of the supporting rods is at least one set, and the mounting frame is fixedly connected with an adjusting mechanism used for adjusting the two sets of U-shaped frames to move reversely. The two sets of inclined baffles are arranged in a V shape, and the inclined angles of the inclined baffles are changed by pushing and pulling the inclined baffles through the supporting rods when the frame shaped like the Chinese character'fang 'slides, and the beneficial effects are that the two sets of inclined baffles arranged in the V shape are arranged to restrain the two sides of the animal body, so that the animal body is difficult to greatly roll left and right or twist, and work can be conveniently carried out; angles of the two groups of inclined baffles are adjustable, and use is flexible.

The utility model relates to sampler technical field discloses an electric vagina sampler, including handle mechanism, the handle mechanism front end threaded cover is equipped with extraction mechanism, the handle mechanism outer surface front side position is provided with the mechanism of propping open, two the propping open mechanism includes the installation box, two the waterproof telescopic link of installation box opposite outer side inner wall fixed setting has, two waterproof telescopic link opposite inner side fixed setting has waterproof multistage telescopic link, two waterproof multistage telescopic link front end fixed setting has the connection box, two connection box front end threaded cover is equipped with the protective cover, the handle mechanism includes protective housing. In the utility model, the combination of waterproof telescopic link and waterproof multistage telescopic link in the propping open mechanism of the device can flexibly adjust the position of the protective cover, which can prevent the extraction mechanism from scratching other positions in the early stage, effectively support the inside in the middle stage, facilitate sampling operation, and the one-time use of the protective cover can avoid cross infection and improve the sanitary safety.
