Base used for installation of mineral dust sampler

Abstract

The invention discloses a base used for installation of a mineral dust sampler. The base comprises at least three support rods, a bearing plate and a rotating shaft, wherein one ends of the support rods are movably chained with the lower surface of the bearing plate through a connecting piece, the angles between the adjacent support rods are the same, the length of each support rod is adjustable,the rotating shaft is arranged on the upper surface of the bearing plate and positioned on the axis of the bearing plate, and one end, far away from the bearing plate, of the rotating shaft is provided with a clip. Under the condition of changing acquisition points, a worker can rapidly adjust the vertical direction and the horizontal direction of the mineral dust sampler, the adjustment time is saved, the labor cost is saved, and the work efficiency is increased.

Description

technical field [0001] The invention relates to a mine dust sampler, in particular to a base for installing the mine dust sampler. Background technique [0002] Dust refers to solid particles suspended in the air. It is customary to have many names for dust, such as dust, dust, smoke, mine dust, sand dust, powder, etc. These terms have no obvious boundaries. The International Organization for Standardization stipulates that suspended solids with a particle size of less than 75 μm are defined as dust. The presence of dust in the atmosphere is one of the main reasons for maintaining the temperature of the earth. Too much or too little dust in the atmosphere will have a catastrophic effect on the environment. But in life and work, productive dust is the natural enemy of human health and the main cause of various diseases. [0003] Dust sampler refers to a portable device for collecting dust samples in dusty air. It is widely used in health monitoring and evaluation of disea...

Problems solved by technology

[0005] The invention solves the need to adjust the collection location and the collection orientation of the mine dust sampler existing in the prior art during use. The traditional method is to adjust the orientation by manually moving the entire bracket, which is inconvenient to adjust; The height of the mine dust sampler from the ground is too low during use. Due to environmental reasons, sludge enters the mine dust sampler and affects the accuracy of dust concentration detection. It is provided for the installation of the mine dust sampler. The base can be adjusted in the vertical and horizontal directions without moving the mine dust sampler during application, which is convenient for the staff to operate, saves the staff's adjustment time for the mine dust sampler, and improves the mine dust sampler. Sampler productivity and accuracy
