No-dead-angle plastering device for wall plastering robot

Abstract

The invention discloses a no-dead-angle plastering device for a wall plastering robot, which comprises an ash hopper frame, wherein a lifting frame is slidably arranged on the ash hopper frame and a lifting driving device is connected between the lifting frame and the ash hopper frame; a plastering plate is rotationally arranged at one end of the lifting frame near the wall, the plastering plate comprises an upper plastering station and a lower plastering station, and the plastering plate is connected with a station switching device and a station holding device; an ash storage hopper is rotationally arranged on the ash hopper frame, an ash spraying gun is arranged at the lower part of the ash storage hopper, and a slurry spraying angle adjusting device is arranged between the ash storage hopper and the ash hopper frame; the lifting frame is provided with a slurry supporting device. According to the no-dead-angle plastering device for the wall plastering robot, the plastering plate canbe lifted up and down, and plastering of the top and the bottom of cavity can be realized through station switching, so that a plastering dead angle is avoided; the spraying angle is adjustable, and the mortar can be smoothly sprayed on the wall surface by matching with the plastering plate at different working positions; a certain height difference exists in the up and down of the plastering plate, so that more ash storage heights are provided to the ash storage hopper, the high ash storage amount can be realized, and the strength of manual ash continuation is reduced.

Description

technical field [0001] The invention relates to the technical field of wall plastering robots, in particular to a plastering device without dead ends for a wall plastering robot. Background technique [0002] The vertical walls in residential buildings, office buildings, schools, hospitals and other buildings usually need to be plastered. The walls that can be plastered include cement walls, brick-concrete walls, hollow brick walls, etc. The plasters that can be plastered include foam mortar, dry powder mortar, and gypsum. etc., the thickness of the plaster is mostly 5-20mm. [0003] At present, various wall plastering machines are used to replace manual wall plastering and improve the efficiency of wall plastering construction. The structure of the existing wall plastering machine usually includes a base frame, on which the double columns that can be retracted are fixed, and the top frame is set on the top of the double columns, and the structures such as the plastering he...

AI Technical Summary

Problems solved by technology

These wall plastering machines have many disadvantages: 1. Due to the size limitation of the whole machine, the storage capacity of the ash storage bucket is small. During the process of rising and plastering the wall, it is necessary to manually add mortar in the first half of the rising. The manual labor intensity is relatively large. When it is high, the mortar in the ash storage hopper is unsustainable, and the top of the wall cannot be plastered; 2. The mortar flowing from the ash storage hopper to the plastering head has great uncertainty. Insufficient supply of mortar forms pits, and now the method of excessive supply of mortar in the ash storage hopper is usually adopted. This method tends to cause more mortar to pour from both ends of the plastering head, resulting in greater waste; 3. The lower part is affected by the height of the chassis The upper part is limited by the structure of the top frame, ash storage hopper and electric box. There are plastering dead spots on the upper and lower parts of the vertical wall. The plastering dead spots need to be processed manually, which increases the labor intensity and reduces the Productivity
