Description

Chalk dust cleaning device

Technical Field

The utility model relates to a cleaning device, in particular to a chalk dust cleaning device.

Background

Most of traditional blackboards use chalk for writing, in order to clean chalk dust, a dust groove with the same length as the blackboard is generally formed in the lower end of the blackboard, and the falling chalk dust can fall into the dust groove. When the chalk dust needs to be cleaned, the chalk dust is cleaned by using tools such as a brush, a rag and the like. However, when such an ash chute is cleaned, the chalk dust may fly or fall off, which may adversely affect the environment and human body.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims to provide a chalk dust cleaning device which is simple in structure and convenient to operate.

The technical scheme is as follows: the chalk dust cleaning device comprises a collecting box, a push plate and a pulley; the collecting box is of a square structure, the upper portion of the collecting box is hollow, the pulleys are mounted above the side walls of the two sides of the collecting box and are connected with the bottom of the ash groove through sliding grooves, one end of the push plate is connected with the upper portion of the collecting box, and the push plate is placed on the upper portion of the ash groove and used for pushing chalk ash to one end of the blackboard.

Further, the push plate is integrally wrapped with cloth.

Further, the push plate is positioned in the middle of the upper part of the collecting box.

Further, the push plate is positioned at one side of the upper part of the collecting box.

Further, the number of the pulleys is 4-6.

Further, the collecting box is 8-12cm in length, 8-12cm in width and 5-6cm in height.

Has the advantages that: compared with the prior art, the utility model has the following remarkable advantages: the chalk dust cleaning device is simple in structure and convenient to operate, collection and cleaning of chalk dust are facilitated, adverse effects on the environment and human bodies during chalk dust cleaning are reduced, and the classroom environment is purified.

Detailed Description

The technical scheme of the utility model is further explained by combining the attached drawings.

As shown in fig. 1 and 2, wherein, 1, a push plate, 2, a collecting box, 3 pulleys, 4 ash grooves and 5 sliding grooves, the utility model is composed of the collecting box, the push plate, the pulleys and the like (see fig. 1). The push plate is positioned on one side of the collecting box and used for pushing chalk dust to one end of the blackboard, the height of the push plate is 5-6cm, the whole push plate is wrapped by cloth, the dust cleaning effect is better, and the dust groove is protected. The collecting box is used for collecting the cleaned chalk dust, the width of the collecting box is about twice (10cm) of the dust groove, the length of the collecting box is 10cm, the height of the collecting box is 5-6cm, and the function of the collecting box is to prevent the chalk dust from falling outside. The pulleys are used for pushing the whole device, are totally 4, are arranged on two sides of the collecting box and are connected with the bottom of the ash groove through sliding grooves

When the dust needs to be cleaned, the cloth of the push plate is wetted by water firstly, so that the dust cleaning effect is better. The device is arranged on the dust groove, the push plate is pushed to the other end from one end of the blackboard, so that the chalk dust falls into the collecting box, and finally the device is taken down from the dust groove, and the chalk dust in the collecting box is cleaned.
