AI Technical Summary
During the production process of concrete prefabricated parts, the concrete is relatively viscous, causing unevenness on the top. When using the smearing machine directly, the concrete in the protruding parts will overflow, and the smearing parts cannot be smoothed normally, which affects the quality of the smearing and leads to waste of concrete.
A matte machine for concrete prefabricated parts is designed, including electric slide rails, matte components, V-shaped push plates and cleaning components. The smear assembly is driven by the electric slide rail, and the concrete is flattened before the smearing is smeared. The components collect the excess concrete, and the components are cleaned to clean the smear discs and the bottom wall of the V-shaped smear plate to avoid concrete settling.
Through the leveling operation of the V-shaped push plate, the light smearing process can be accelerated, avoid concrete overflow and waste, ensure the quality of light smearing, and prevent concrete from solidifying by cleaning components, ensuring the smooth progress of subsequent light smearing operations.

[0036] A troweling component, which includes an L-shaped plate 6. The L-shaped plate 6 is fixed at the bottom end of the cylinder 5. A first motor 7 is fixed on the side wall of the L-shaped plate 6, and a polishing disc 8 is detachably fixed at the power output end of the bottom of the first motor 7;
[0037] A V-shaped push plate 9, which is fixed on the side wall of the L-shaped plate 6 through a connecting plate 10;
[0038] The cleaning component 12 is fixed to the support leg 2 through a connecting rod 14, and a collecting component 13 is installed at the bottom end of the cleaning component 12.
[0039] The bottom wall of the V-shaped push plate 9 is flush with the bottom wall of the finishing disc 8.
[0040] In this embodiment, the electric slide rail 3 and the electric slider 4 are arranged to drive the finishing component to move, so as to perform a finishing operation on the concrete in the precast mold 11. The cylinder 5 is arranged to control the up and down movement of the finishing component, so that the finishing disc 8 can be attached to the top wall of the precast mold 11. The first motor 7 drives the finishing disc 8 to rotate to perform a finishing operation on the concrete. By arranging the V-shaped push plate 9, the concrete on the top of the precast mold 11 can be leveled before the finishing operation, and the excess concrete is left inside the V-shaped push plate 9. When passing through the concave part, the excess concrete will fill the concave part, which can speed up the subsequent finishing operation.

Then, the polishing disc 8 contacts the top wall of the scraper 121, and the scraper 121 scrapes off the concrete at the bottom of the polishing disc 8. To accelerate the cleaning of the polishing disc 8, the first motor 7 can also be turned on to drive the polishing disc 8 to rotate, thereby cooperating with the scraper 121 to quickly clean the bottom wall of the polishing disc 8. To prevent concrete from coagulating on the scraper 121 and affecting the subsequent cleaning of the V-shaped push plate 9 and the polishing disc 8, a sliding sleeve 122 is further provided on the outer side of the scraper 121. The second motor 126 drives the screw 125 to rotate, and the screw 125 drives the sliding sleeve 122 to move through the screw block 123, thereby cleaning the surface of the scraper 121.
[0050] The collecting component 13 includes a placing plate 131, and the placing plate 131 is fixed to the bottom wall of the scraper 121 through a vertical rod 132. A collecting box 133 is placed on the placing plate 131.
