3results about How to "Realize automatic sampling" patented technology

The application provides a sampling device and a sampling method, relates to the technical field of mining material sampling, and aims to solve the problems of blind coverage, human error, low efficiency, high labor intensity, and poor working environment in the traditional manual sampling mode to some extent. The sampling device provided by the application comprises a stand, a first cantilever, a second cantilever, a mast and a spiral sampling mechanism. The first end of the first cantilever is rotatably connected to the top of the stand. The first end of the second cantilever is rotatably connected to the second end of the first cantilever. The top of the mast is connected to the second end of the second cantilever. The mast comprises a lifting mechanism. The spiral sampling mechanism is connected to the mast through the lifting mechanism and can be lifted along the mast through the lifting mechanism. The spiral sampling mechanism comprises a sampling drive, a spiral sampling head and a sampling assembly. The output end of the sampling drive is connected to the spiral sampling head. The sampling assembly is used for collecting the material collected by the spiral sampling head.

The utility model discloses a device for collecting greenhouse gas in a greenhouse, and solves the technical problem that the greenhouse gas in the greenhouse is difficult to collect due to high temperature when the existing gas concentration detection method is difficult to be applied to the greenhouse closing period. The device comprises a supporting pipe, a silica gel hose, an air exhaust pipeline, an air exhaust device and an air storage bag, a plurality of small holes are sequentially formed in the supporting pipe, the silica gel hose is arranged in the supporting pipe, one end of the silica gel hose extends out of the small holes of the supporting pipe to be communicated with the interior of the greenhouse, the other end of the silica gel hose is communicated with the air exhaust pipeline, the air exhaust pipeline is communicated with the air exhaust device arranged outside the greenhouse, and an air outlet of the air exhaust device is connected with the air storage bag. The air exhaust device provides power, and air in the greenhouse is exhausted out of the greenhouse through the silica gel hose and the air exhaust pipeline. The greenhouse gas collecting device is low in manufacturing cost, simple in structure and convenient to disassemble and assemble, the storage battery is arranged on the greenhouse gas collecting device so that the greenhouse gas in the greenhouse can be conveniently used outdoors, and the function of automatically collecting greenhouse gas in the greenhouse during the high-temperature greenhouse closing period in summer is achieved.

The utility model provides a kind of automatic material taking mechanism of cement bucket, including cement bucket, the cement bucket includes cement bucket body and mounting plate installed on the outer wall of cement bucket body and is integrated with cement bucket body, the cement bucket body includes cement bucket output pipe in its bottom, the mounting plate is horizontally arranged, pneumatic vibrator is installed at the top of the mounting plate, the rotating pressure air cylinder opposite to pneumatic vibrator is installed at the bottom of the mounting plate, the rotating pressure air cylinder cylinder rod bottom is equipped with the sealing plate that can seal cement bucket output pipe, the cement bucket is fixed on support by mounting plate, the utility model is realized by the cooperation of pneumatic vibrator, rotating pressure air cylinder and sealing plate automatic sampling of cement, compared with artificial sampling, it is not easy to cause sampling standard inconsistency due to fatigue or negligence, in turn affect the comparability of detection result, also not easy to produce dust raising, in turn affect human health.
