Description

Technical Field

[0001] The utility model relates to the technical field of concrete slab production devices, in particular to a trowel device for concrete slab production. Background Art

[0002] Concrete slabs are indispensable building materials in the construction industry. Specifically, during their production, mixed concrete is usually injected into a mold for concrete slab production, solidified, and then a concrete slab is generated. However, during the production of concrete slabs, after the concrete is injected into the mold, it usually goes directly to the next processing procedure. However, when the concrete is injected, it contains air and the particles of the concrete are of different sizes. Directly processing it into a concrete slab will affect its quality, and the surface of the produced concrete slab has bubbles, which is not beautiful and affects its sale. For this reason, we have proposed a smoothing device for concrete slab production. Utility Model Content

The ends of the two hydraulic rods are movably sleeved with a connecting plate, and the connecting plate and the connecting rods are fixed to each other.

[0006] Optionally, an inclined support frame is fixed to the top of the rotating sleeve, a flushing pipe located directly above the connecting rod is installed on the support frame, and a plurality of nozzles are arranged below the flushing pipe, and the nozzles can clean the connecting rod.

[0007] Optionally, a water pipe is provided below the flushing pipe to supply water thereto.

[0008] Optionally, a plurality of balls are arranged below the sliding block, and the balls contact the sliding groove to reduce friction between the sliding block and the sliding groove.

[0009] Optionally, a bearing seat is provided at the end of the screw, and the bearing seat is located on the sliding groove plate to support it.

[0010] The utility model has the following beneficial effects:

[0011] 1.
