Description

Technical Field

[0001] The invention relates to the field of soil pollutant detection, and in particular to a sampling mechanism of a slag detection device. Background Art

[0002] The development of a city is inseparable from the beautification of the city. Environmental sanitation is the key. Creating a sanitary city is the first step to take in urban development. However, with the accelerated development of urban construction in recent years, the construction of high-rise buildings and the paving of roads have sprung up like mushrooms after a spring rain, and they are increasingly showing a high-density and unconventional trend, resulting in a sharp increase in the amount of slag generated, and an increase in the number of vehicles transporting construction sites. Therefore, the phenomenon of stealing and dumping slag often occurs in society. Slag trucks are often overloaded and speeding, driving illegally, and often do not drive according to the prescribed routes. At the same time, due to overloading and speeding, and poor coverage, dust is raised along the road during the entire driving process, and slag is often left behind, causing serious pollution to the urban environment, affecting people's health, and threatening people's life safety.

[0003] At present, when testing the slag loaded in the dump truck, it is necessary to manually collect and prepare a small amount of soil samples from the dump truck for testing. Because the slag may be contaminated by heavy metals and volatile organic gases, the sampling of the slag may affect the health of the operators. Summary of the invention

[0004] The purpose of the present invention is to provide a sampling mechanism for a slag detection device in view of the problems that manual sampling may affect the health of operators and the sampling efficiency is low when sampling slag as described in the background technology.

[0005] To achieve the above purpose, the present invention is implemented through the following technical solutions: a sampling mechanism of a slag detection device, which is characterized in that it includes a connecting seat, a driving device and a sampling plate, there are two sampling plates, the two sampling plates are movably connected to the connecting seat, the inner sides of the two sampling plates are provided with accommodating grooves, and the accommodating grooves of the two sampling plates are arranged oppositely, and opposite inclined surfaces are arranged on the upper parts of the two sampling plates, and the distance between the two inclined surfaces gradually increases from top to bottom, and the position of the inclined surfaces is located above the connecting part between the sampling plate and the connecting seat, and opposite stoppers are arranged in the accommodating grooves of the two sampling plates, and the position of the stoppers is It is located below the connection between the sampling plate and the connecting seat, and the distance between the two blocks gradually decreases from top to bottom. The driving device is arranged on the connecting seat, and a top block is arranged at the movable end of the driving device, and the top block is arranged on the inner side of the accommodating grooves of the two sampling plates and is located between the inclined surface and the stop block. The driving device can drive the top block to move up and down. When the top block moves downward, it presses between the two stop blocks, so that the lower parts of the two sampling plates are opened at a certain angle to facilitate sampling of the slag to be tested. When the top block moves upward, it presses between the two inclined surfaces, so that the lower parts of the two sampling plates are closed to clamp the sampled slag.

[0006] A further solution is that the connecting seat is also provided with a pushing mechanism for pushing the sampled slag out of the sampling plate, the pushing mechanism includes a fixed seat, a driving member, a connecting arm and a scraper, the fixed seat is fixedly connected to the connecting seat, and the fixed seat is arranged next to one of the sampling plates, the driving member is arranged on the fixed seat, the connecting arm is L-shaped, one end of the connecting arm is connected to the movable end of the driving member, and the other end of the connecting arm extends from the interval between the two sampling plates to between the two sampling plates, the scraper is connected to the connecting arm, and the two ends of the scraper are respectively pressed against the receiving groove of the sampling plate, the driving member can drive the connecting arm to move up and down, and then drive the scraper to move up and down, and push the sampled slag downward to the outside of the sampling plate. By setting up a pushing mechanism, the sampled slag in the sampling plate can be pushed out and returned to the slag truck, which will not affect the subsequent sampling and detection.

[0007] A further solution is that the scraper includes two inclined plates, which are arranged at a certain angle, the upper end of the inclined plate is connected to the connecting arm, and the lower end of the inclined plate is pressed into the receiving groove of the sampling plate on the corresponding side, and a pusher is provided at the lower end of the inclined plate, and the pusher includes an arc portion arranged along the longitudinal direction of the receiving groove and a transverse plate arranged transversely, the arc portions of the two pushers are arranged oppositely, and the two transverse plates are arranged crosswise.

By providing the guide column, the connecting arm can be lifted and lowered vertically, and the ejection mechanism is prevented from being deflected under the influence of resistance, which may cause damage to the ejection mechanism.

[0009] A further solution is that the connection seat is connected to a lifting drive device, and the lifting drive device drives the connection seat to rise and fall, so that the sampling plate is lowered and inserted into the slag for sampling, and after sampling, the slag is lifted to a height corresponding to the detector. By setting the lifting drive device, the sampling plate can be automatically inserted into the slag to a certain depth, and the sampling of the slag is more representative.

[0011] A further solution is that the sampling plate comprises a top inclined surface, a middle body and a lower pointed portion, and the receiving groove is arranged at the portion of the middle body below the pushing mechanism and the inner side of the pointed portion. With this arrangement, the sampling plate can be more easily inserted into the slag to a certain depth, and the soil in the middle part of the slag layer can be obtained, so that the detection result is more accurate.

[0012] A further solution is that a protection rod is provided at the lower part of the sampling plate, one end of the protection rod is fixedly connected to one sampling plate, the other end of the protection rod extends to the edge of another sampling plate, and protection rods are provided on both the front and rear sides of the sampling plate.
