Reciprocating type sport competition long jump sandpit trowelling machine

Abstract

The invention discloses a reciprocating type sport competition long jump sandpit trowelling machine. The reciprocating type sport competition long jump sandpit trowelling machine comprises a cement floor; the top of the cement floor is fixedly connected with a take-off plate; a sandpit positioned on the back side of the take-off plate is arranged at the top of the cement floor; the top of the cement floor is fixedly connected with a first connecting plate and a second connecting plate sequentially from left to right; a through groove is formed in each of the close sides of the first connectingplate and the second connecting plate; a second through groove positioned below the first through groove is formed in each of close sides of the first connecting plate and the second connecting plate. An electric push rod, a connecting block, a U-shaped plate, a rotating rod, a rotating wheel and a sliding rail are provided, so that a controller can control the electric push rod to move; furthermore, the connecting block moves up and down and the rotating wheel on the U-shaped plate can move on the sliding rail, so that stability is achieved when the connecting block moves, namely a threadedrod moves downwards, and trowelling is facilitated.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a reciprocating long jump bunker smoothing machine for sports competitions.
