This kind of scheme achieves the purpose of pulping through the vibration of the motor. The structure is complex and is suitable for specific occasions or open plane occasions, but it is difficult to apply to ordinary buildings.

Detailed ways

A hand-held self-elevating concrete slurry and surface removal device, as shown in Figures 1, 2 and 3, comprises a horizontally arranged support frame 1, and a chute 4 is provided on both sides of the support frame 1, and the chute 4 is open Inwardly, there is a sliding rod 5 in the chute 4, the lower end of the sliding rod 5 is connected to the pulping surface, a troweling plate 9 is provided at the front of the support frame 1, and an L-shaped handle 6 is provided on the upper part of the sliding groove 4, and the L-shaped handle There is a pressure handle 7 on the 6, the pressure handle 7 is connected with the L-shaped handle 6 through the bracket 13, and the pressure handle 7 is hinged on the bracket 13, the end of the pressure handle 7 is connected to the pull wire 10, and the bracket 13 is provided with a pull wire hole, The pull wire 10 passes through the pull wire hole, the other end of the pull wire 10 is connected to the sliding rod 5 , and the pull wire 10 passes through the opposite L-shaped handlebar 6 .

The chute and the plane of the support frame 1 are at an angle of 70°-80°.

Press the handle 7 down and rotate with the bracket 13 as the axis to drive the pulling wire 10 to move. The pulling wire 10 finally drives the sliding rod 5 to move up and down along the chute 4, so that the slurry surface continuously beats the concrete.

As shown in FIGS. 4 and 5 , the front end of the support frame 1 is provided with a card slot 8 , and the rear side of the troweling plate 9 is provided with a vertical card, which is locked in the card slot 8 . The connection between the support frame 1 and the troweling plate 9 is realized.

The outer corners at the corners of the troweling plate 9 are arc-shaped. Prevent the phenomenon of smearing during the smoothing process, ensure smooth smoothing movement, and ensure the surface quality.

As shown in FIGS. 6 and 7 , the support frame 1 is welded with four angle steels to form a rectangular frame structure, and the pulping surface includes a face frame 2 and a steel mesh 3 inside the face frame 2 .

The length of the outer long side a1 of the support frame 1 is 1000mm-1200mm, and the length of the outer wide side b2 is 500mm-600mm, which provides sufficient contact area for pulping, but does not exceed the operator's body capacity.
