A kind of spraying machine and spraying method

Abstract

The invention relates to the field of spraying and particularly relates to a spraying machine and a spraying method, which are applied to spraying construction in economically underdeveloped areas. The spraying machine comprises a shell, an impeller, a crank and a strength controller, wherein the shell is provided with a material hole and a crank fixed hole; the impeller is located in the shell and a penetrating hole is formed in the middle of the impeller; one end of the crank can penetrate through the crank fixed hole so that the impeller is fixed in the shell and the other end of the crank is located on the outer side of the shell to be suspended; the crank is rotated so that the impeller is driven to rotate, and materials in the shell are stirred; and the strength controller can be used for adjusting a compressed degree of a resilient sheet. When the spraying construction is carried out in the economically underdeveloped areas, maintenance pressure and purchasing pressure of maintenance parts are reduced, and maintenance cost and maintenance difficulties are greatly reduced; dependence on pneumatic-electric spraying is reduced, and learning and utilization difficulties of operators are reduced; local resources are sufficiently utilized, importing cost is reduced, and the requirements on skills of the operators are greatly reduced; and the spraying quality is relatively good.

Description

technical field [0001] The invention relates to the field of spraying, in particular to a spraying machine and a spraying method used in economically underdeveloped areas for spraying construction. Background technique [0002] At present, in the spraying of exterior wall paint, decorative plastering, and plastering roughening, spraying operations mainly use highly automated machinery. For example, air pumps are used for spraying operations, but the disadvantage of using air pumps for spraying operations is that the spraying speed Not easy to control. Moreover, in economically underdeveloped regions such as West Africa, these tools are mainly imported from abroad, and it is difficult to maintain after mechanical damage during use, and it is very inconvenient to replace parts. In addition, the spraying construction process is also limited by the length of the air pipe, and the frequent damage of the air pipe affects the smooth progress of the construction. In addition, the ...
