Mortar spraying and smearing machine and method for painting mortar on wall surface by using mortar spraying and smearing machine

Abstract

The invention relates to a mortar spraying and smearing machine and a method for painting mortar on a wall surface by using the mortar spraying and smearing machine. The mortar spraying and smearing machine comprises a mortar supply mechanism and a spraying and leveling mechanism, wherein a fixed lower door frame is arranged on a base, sliding upper door frames are respectively connected in the fixed lower door frame in an inserted way, in addition, the top of the fixed lower door frame is connected with a main cross beam, a door frame lifting hoist can tract the sliding upper door frames to ascend, a work table capable of sliding along the fixed lower door frame and the sliding upper door frames is arranged on the fixed lower door frame, a work table lifting hoist can track the work table to ascend, a spray nozzle capable of being used for spraying and coating the mortar and a scraper capable of leveling the mortar are arranged on the work table, and the spray nozzle can leftwards and rightwards move on the work table. During the mortar painting, th spray nozzle moves leftwards and rightwards and simultaneously ascends along with the work table for realizing the reciprocating mortar spraying from the bottom to the top, after the spray nozzle reaches the top, the work table vertically descends, and leveling and calendaring are performed on the surface of the mortar by the scraper. The machine and the method provided by the invention can adapt to the floor height, and can realize automatic mortar spraying and leveling, in addition, operators can always feed materials at the lowest position, and the work intensity is greatly reduced.

Description

technical field [0001] The invention relates to a mortar spraying machine, and also relates to a method for making wall flour mortar by using the mortar spraying machine, which belongs to the technical field of construction machinery. Background technique [0002] At present, most of the wall construction has not been mechanized, and a large part of the wall construction relies on manual construction, which has high construction strength, low efficiency, and unsatisfactory wall flatness. [0003] There are wall mortar construction machines on the market now, and its column structure has two kinds, and a kind of is non-retractable column, and another kind is telescopic column, and telescopic column realizes expansion and contraction usually by oil cylinder. The method of plastering the mortar on the wall is to install the hopper on the column, the conveyor belt that sends the mortar horizontally is installed in the hopper, and the vibration mechanism is installed on the hoppe...

AI Technical Summary

Problems solved by technology

[0004] Such wall mortar construction machinery has the following disadvantages: (1) Due to the limited mortar storage capacity in the hopper, manual secondary feeding is required. When the hopper moves to a high position and lacks material, feeding is very difficult

When encountering the window, the exit of the conveyor belt will appear hollow and lose the reaction force, while the exit of the conveyor belt is wider, which will cause more mortar to fall to the ground, causing a lot of waste and reducing construction efficiency

(3) The tension between the column and the floor is not easy to grasp through the oil cylinder telescopic column, if the tension is too small, it will easily shift, and if the tension is too large, it will easily damage the floor

In addition, due to the rigid support, even if a large tension is maintained, due to the large vibration during the construction process, it is still possible for the mast to loosen instantly

⑷The hopper loaded with mortar climbs up with the lifting mechanism, which has a large power consumption, which is not conducive to energy saving
