Description

Technical Field

[0001] The utility model relates to the field of sampling devices before garbage excavation, in particular to a spiral sampling device before garbage excavation. Background Technique

[0002] Before garbage excavation, it is necessary to detect it to observe harmful substances in the garbage. Most of the existing sampling devices before garbage excavation use a spiral sampler for sampling, which is convenient for quickly sampling before garbage excavation.

[0003] At present, when the sampler samples garbage, most of the existing ones transport the sampled garbage to the sample storage tube through a spiral shaft and then bring it back. In this way, some garbage with high viscosity is not easy to store during sampling, and the inner wall of the sampler is likely to adhere to garbage after sampling, thus reducing the sampling effect. Content of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a spiral sampling device before garbage excavation to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model proposes a spiral sampling device before garbage excavation, including a sampler body. A through hole is opened at the bottom end of the sampler body, and a plug plate is movably arranged on the inner wall of the through hole;

[0006] A sampling mechanism is arranged inside the sampler body, and the sampling mechanism includes a fixed shaft, a conveying belt, a fixing plate and a scraping plate. One end of the inner wall of the sampler body is rotatably connected to the fixed shaft. A conveying belt is fixedly installed on the outer circle of the fixed shaft. A fixing plate is fixedly installed at the bottom of the outer circle of the fixed shaft. A scraping plate is fixedly installed on the side of the fixing plate away from the fixed shaft, and the scraping plate is connected to the inner wall of the sampler body.

[0007] In an example, a flange is fixedly installed at the top of the sampler body, and a sample storage tube is arranged on the top of the flange.

[0008] In an example, a rotating shaft is rotatably connected to the top end of the sample storage tube, and the rotating shaft penetrates and extends into the sample storage tube.

[0009] In an example, a connecting ring is fixedly installed at the bottom end of the rotating shaft, and the bottom end of the connecting ring is threadedly connected to the top end of the rotating shaft.

[0010] In an example, a mounting plate is fixedly installed at the top end of the rotating shaft, and a handle is fixedly installed on one side of the top of the mounting plate.

[0011] In an example, a sample outlet tube is fixedly installed on one side of the outer circle of the sample storage tube, and a baffle is arranged at the outlet end of the sample outlet tube.

[0012] The spiral garbage pre-excavation sampling device proposed by the present utility model can bring the following beneficial effects:

[0013] 1. For the spiral garbage pre-excavation sampling device, the movable handle drives the rotating shaft to rotate through the mounting plate, which drives the fixed shaft to rotate through the connecting ring, and then drives the conveying track to rotate, conveying the garbage to be sampled into the sample storage tube for storage, and then discharging it through the sample outlet tube, so as to achieve the effect of sampling before garbage excavation.

[0014] 2. For the spiral garbage pre-excavation sampling device, the rotation of the fixed shaft drives the fixed plate to make a circular motion, which drives the scraper to make a circular motion, scraping the inner wall of the sampler body, cleaning the garbage adhering to the inner wall, and preventing the garbage from adhering to the inner wall.
