Air collecting device convenient for saving labor

Abstract

The invention discloses an air collecting device convenient for saving labor. The air collecting device convenient for saving labor comprises a base. The base is a hollow structure. The inner wall ofthe bottom of the base is rotatably connected with a support rod through a ball bearing. The upper end of the support rod is stretched out of the base through an opening installed at the upper end ofthe base and fixedly connected with an air hose. The rod wall, positioned in the base, of the support rod is fixedly sheathed with a gear. The inner wall of the bottom of the base is fixedly connectedwith two locking plates symmetrically installed relative to the gear. A same reciprocated screw rod is rotatably connected between the two locking plates through the ball bearing. The surface of oneof the locking plates is fixedly connected with a motor. An output shaft of the motor passes through the surface of the locking plate through a through hole installed on the surface of the locking plate and is fixedly connected with one end of the reciprocated screw rod. The rod wall of the reciprocated screw rod is in threaded connection with a moving block. One end, adjacent to the gear, of themoving block is fixedly connected with a rack meshed with the gear. The air collecting device is capable of automatically swinging forwards and backwards and collecting air, saving a labor force, andperforming stable limiting fixation on a connecting place of an air balloon.

Description

technical field [0001] The invention relates to the technical field of environmental protection engineering, in particular to a convenient and labor-saving air collection device. Background technique [0002] In environmental protection projects, it is often necessary to sample and analyze the air in the area to detect the local air quality. The traditional collection method uses the hand-held collector to swing left and right to collect the air, which is laborious and inconvenient. Air is collected through the balloon, and there is no specific limit mechanism at the air outlet of the balloon sleeve, which may easily cause the balloon to detach. Sometimes people need to hold the balloon to limit and fix it, which is inconvenient to use. Contents of the invention [0003] The purpose of the present invention is to solve the problem of air collection in the prior art by swinging left and right hand-held collectors by the staff, which is relatively laborious and inconvenient,...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem of air collection in the prior art by swinging the staff hand-held collector to the left and right, which is relatively laborious and inconvenient, and most of the air is collected by balloons at present, and the balloon sleeve is not located at the air outlet. The specific limit mechanism is easy to cause the balloon to detach, and sometimes people need to hold the balloon to limit and fix it, which is inconvenient to use. A convenient and labor-saving air collection device is proposed
