Abstract

The invention relates to a back box, in particular to a back box for cobblestone laying. The technical problem to be solved by the present invention is how to design a back box for cobblestone laying which does not require manual bending or squatting during operation, which makes it easier for workers to work and thus improves work efficiency. The invention provides such a back box for cobblestone laying, comprising: a belt type back box, the top of which is connected with a detachable plug cover, the discharge end of the bottom of the belt type back box is connected with a feeding pipe, and the end of the feeding pipe is connected An extension pipe is connected, and the belt-type back box is communicated with the extension pipe through the feeding pipe; the adjustment component is arranged on the extension pipe; the quantitative component is arranged on the extension pipe. In the present invention, the cobblestone is laid at the position to be laid by the coordination of the adjustment component and the quantitative component, so as to achieve the effect of laying the cobblestone.

Description

technical field [0001] The invention relates to a back box, in particular to a back box for cobblestone laying. Background technique [0002] Cobblestones are named because they resemble cobblestones. As a kind of pure natural stone, cobblestone is taken from the sandstone mountain produced by the uplift of the ancient river bed after the crustal movement thousands of years ago. When some parks and other buildings are built, it is usually necessary to lay some cobblestones to make the scene more beautiful. [0003] At present, the way of laying cobblestones is usually to manually bend or squat down to press the cobblestones one by one at the position where the cobblestones need to be laid. The above-mentioned methods need to be manually bent or squatted for laying, which is very easy to fatigue when laying. affect work efficiency. [0004] Therefore, it is necessary to develop a back box for cobblestone laying that does not require manual bending or squatting for laying, ...
