The invention discloses air particulate matter concentration detection equipment, and relates to the technical field of air detection.The air particulate matter concentration detection equipment comprises a main body and an air inlet
pipe, a support is installed in a connector of the air inlet
pipe and the main body, a second motor is installed in the middle of the support, and blades are installed on an operating shaft of the second motor; the device has the advantages that the first motor of the flow guide
assembly drives the rotating frame to rotate, the angle of the flow guide plate can be adjusted to guide air into the air inlet, the air inflow is increased, it is ensured that an
air sample is fully obtained in time, mounting and dismounting are convenient, the flow guide
assembly can be easily taken down when equipment is transferred, and meanwhile the position of the air inlet
pipe can be adjusted by screwing a rotating wheel; the main body is rotationally placed on the placing frame behind the main body, so that the vertical occupied area is reduced, obstruction is avoided when the equipment is moved, the main body can be fixed on the bearing frame through the mounting frame, the sliding block, the clamping block and the like during mounting, different mounting scenes are adapted, the mounting efficiency is improved, the operation stability is ensured, and the equipment universality is improved.
