Abstract

The invention relates to an auxiliary sanding equipment for standing long jump, comprising a frame-type support frame, four corners of the bottom of the frame-type support frame are fixed with telescopic outriggers, and rollers are fixedly connected to the bottom of each telescopic outrigger; Two parallel support rods are fixedly connected between the two short sides of the frame-type support frame, and a threaded screw is fixedly arranged between the two support rods; the bottom of a slider is designed to slide and fit with the two support rods There is a chute in the center of the slider and a threaded hole for the lead screw to pass through and cooperate with; a lifting cylinder is fixedly connected to the bottom of the slider, and the telescopic rod end of the lifting cylinder is fixedly connected to the second motor. The second motor A paving plate is fixedly connected to the output shaft of the frame type support frame; a sand bucket is fixedly connected between the two long sides of the frame support frame and the two support rods. Through the structural design of the present invention, the sand is discharged from the front and rear sides, and the middle paving plate is rotated and paved, so that the working efficiency can be effectively improved.

Description

Technical field [0001] The present invention relates to the field of sports training equipment technology, in particular to a standing long jump auxiliary equipment sanded. Background technique [0002] Standing long jump is a traditional track and field events, standing long jump requires athletes to not use run-up to start off from the standing posture, the way will only be allowed to jump off the ground again, the long jump is the distance from the nearest foot jumper after jumper to jump from the floor the distance between the heels. The prior art is clearly shown by the bunker to jump landing after heel position, bunker typically at least 2.75m wide, long jump distance from the distal end of the ramp leading edge of the bunker at least 10m, with a sand pit surface in a launching pad horizontal plane, the thickness of the sand in about 80cm. Long before each time, the need in the sand bunker, in particular sand bunker spread flat intermediate portion, and a take-off line as a...
