Dust collecting and weighing device

Abstract

The invention provides a dust collecting and weighing device. The dust collecting and weighing device comprises a support frame; a pair of first synchronous belts are arranged in the support frame inparallel; a first guide rail is arranged below each first synchronous belt; each first guide rail is installed with a walking sliding block; the walking sliding block is fixed on the corresponding first synchronous belt; a second guide rail is arranged between a pair of walking sliding blocks; a dust collecting sliding block is installed on the second guide rail; the dust collecting sliding blockis fixed on a second synchronous belt; and a dust collecting assembly is connected onto the dust collecting sliding block. The dust collecting and weighing device in the invention has the benefits that: the dust collecting assembly performs alternating movement along the direction parallel to the second guide rail and the direction vertical to the second guide rail, so that dust collection is carried out; the problem that artificial collection wastes time and labour is overcome; furthermore, interference of human factors is avoided; the error is effectively reduced; the grammage of the accumulated dust obtained by putting accumulated dust collected by the dust collecting assembly on a precision balance to weigh is the evaluation index by taking the grammage as the cleanness unit; and the device is also suitable for performing dust collecting and weighing in places needing to be detected, such as a factory and a classroom.

Description

technical field [0001] The present application relates to the technical field of dust suction weighing, in particular to a dust suction weighing device. Background technique [0002] "Determining cleanliness with grams" is a road dust assessment standard derived to ensure "APEC blue", specifically referring to the 1m 2 The weight of dust accumulated on the road should not exceed the standard number of grams. At present, when the road dust is "cleaned by grams", manual methods are mostly used, that is, manual sweeping of 1m 2 The accumulated dust on the road is collected, and then the collected dust is weighed to obtain the grams of the accumulated dust, and the obtained grams are used as the evaluation index of "clean by grams". This method of manually collecting dust is time-consuming and laborious, and there is interference from human subjective factors, resulting in large errors. Contents of the invention [0003] The purpose of this application is to address the abo...

Problems solved by technology

By adopting the above technical solution, when the second synchronous belt rotates, it drives the dust suction slider to slide along the second guide rail, so that the dust suction slider drives the dust collection assembly to move along the direction parallel to the second guide rail; when the first synchronous belt rotates, it drives the travel slider The block slides along the first guide rail, thereby driving the dust collection assembly on the dust suction slider to move in the direction perpendicular to the first guide rail, and the dust collection assembly moves alternately in the direction parallel to the second guide rail and perpendicular to the second guide rail while collecting dust. , thus completing the inner 1m of the support frame 2 The collection of dust in a large area overcomes the time-consuming and labor-intensive problem of manual dust collection, and there is no interference from human factors, which effectively reduces the error; the dust collected by the dust collection component is placed on a precision balance for weighing The obtained gram of accumulated dust is the evaluation index of road "clean by gram"
