Cement surface trowelling device for partition construction

Abstract

The invention relates to a cement surface trowelling device for partition construction. The device comprises a bottom plate, a hand pipe, a limiting plate, a trowelling mechanism, an air seat mechanism, and a lifting mechanism; two large guide columns and a motor are arranged on the bottom plate; the top ends of the two large guide columns are connected through a top plate; a bearing seat is further installed on the bottom face of the top plate; a screw rod is arranged on an action shaft of the motor; the motor not only drives the screw rod to enable the trowelling mechanism to lift, but also is provided with the lifting mechanism between an action shaft of the motor and the air seat mechanism arranged at the front side of a lifting frame; and when the motor is electrified to work, the air seat mechanism is promoted to be compressed upwards by the air seat mechanism, so that air in an inner cavity of the air seat mechanism is discharged outwards. The discharged gas can be applied to cleaning the trowelling mechanism, so that a mud layer left on the rear surface of the trowelling mechanism during cement scraping is cleaned downwards. In order to improve the structural rationality of the trowelling mechanism, a scraper element discharges mud to the two sides when receiving and taking the mud falling off from a wall surface, and in actual use, supporting hoppers can be additionally arranged at the two sides to perfectly receive and take the mud.

Description

technical field [0001] The invention relates to the technical field of plastering building construction, in particular to a cement surface plastering device for partition construction. Background technique [0002] During the construction of the courtyard, it is necessary to add a partition wall between the courtyard and the courtyard door, and decorate murals on the partition wall to make the courtyard beautiful. The outer wall of the partition wall made of bricks needs to be reinforced with cement first, and then used Ceramic tiles and murals are finally decorated on the wall. Among them, the cement reinforcement link is the most important. If the surface of the cement layer is unevenly loaded, it will lead to uneven mud surface, which will make the follow-up work impossible.

[0002] During the construction of the courtyard, it is necessary to add a partition wall between the courtyard and the courtyard door, and decorate murals on the partition wall to make the courtyard beautiful. The outer wall of the partition wall made of bricks needs to be reinforced with cement first, and then used Ceramic tiles and murals are finally decorated on the wall. The cement reinforcement link is the most important. If the surface of the cement layer is uneven, it will lead to uneven mud surface, which will make the follow-up work impossible.

[0003] The existing construction method for scraping the cement layer is: manually hold a wooden board, paste it on the wall of the cement layer, and scrape it from top to bottom, so that the protruding cement layer is scraped downwards. Beginners use their arms unevenly It will lead to more uneven scraping layer, affect the construction progress, and waste labor, so there is an urgent need to design a functional device to improve work efficiency
