Blackboard eraser dust treatment device for mathematics

Abstract

The invention discloses a blackboard eraser dust treatment device for mathematics. The blackboard eraser dust treatment device for the mathematics comprises a dust collection box and a locking bolt, wherein a movable seat is fixed to one end of the dust collection box, a fixed rod is inserted into the movable seat, fixed buckles are installed on the fixed rod and the inner wall of the dust collection box, a stainless steel spiral spring is arranged between the two fixed buckles, a feeding inlet and a fixed plate are arranged at the top end of the dust collection box, screw hole seats are installed on the side faces of the fixed plate, studs are installed on the screw hole seats, locking heads are installed at one ends of the studs, anti-skid protrusions are evenly distributed on the side surfaces of a plastic pressing plate, a dust discharging pipe is arranged at the center of the bottom end of the dust collection box, and a threaded sealing cover is arranged at one end of the dust discharging pipe. According to the blackboard eraser dust treatment device for the mathematics, a rubber handle is manually pressed to swing two flapping plates up and down, so that the flapping of the blackboard eraser is realized, the dust collection box collects the flapping dust, and the operation is very simple and convenient.

Description

technical field [0001] The invention relates to the technical field of mathematical tools, in particular to a blackboard eraser dust processing device for mathematics. Background technique [0002] Tableware refers to non-edible tools that directly contact food during meals, utensils and utensils used to assist food distribution or food intake. At present, there are also many disposable tableware on the market, which is not good for the environment; there are also some tableware made of degradable materials. Tableware includes complete sets, including metal utensils, ceramic tableware, tea utensils, glass utensils, paper utensils, plastic utensils, and various container tools (such as bowls, saucers, cups, pots, etc.) and hand-held utensils. Utensils (such as chopsticks, knives, forks, spoons, straws, sticks, etc.) and other utensils. And the grinding device is often used in the tableware processing process, but the residue splash produced by the traditional grinding devic...
