Abstract

The invention relates to the technical field of sports equipment, aims to solve the problem that in the prior art, when an existing push plate is used for paving a jumping pit, hard blocks in the jumping pit cannot be loosened, and provides an automatic paving device for jumping pit long jump. The automatic paving device comprises the push plate, wherein the push plate is connected to a drive rod, and a plurality of comb teeth are intermittently arranged on the lower part of the push plate; the push plate is further connected to a preliminary screening plate, a plurality of first screening holes are arranged in the preliminary screening plate, a plurality of second screening holes are arranged in the push plate, and the hole diameter of the second screening holes is smaller than that of the first screening holes; a plurality of crushing rods are arranged on the surface, facing the push plate, of the preliminary screening plate, and the ends, facing the push plate, of the crushing rods are wedge-shaped ends; and a telescopic rod is arranged between the preliminary screening plate and the push plate and sleeved with an elastic piece, and the two ends of the elastic piece are connected to the push plate and the preliminary screening plate respectively.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to an automatic leveling device for bunker long jump. Background technique [0002] Long jump, also known as rapid long jump, is a track and field jumping event, which is composed of actions such as approach, take-off, vacating and landing. Athletes or students run up in a straight line, take off with one foot after the front line of the springboard, go through the air stage, and then land with both feet in the bunker. The ranking is determined by the distance of the jump during the competition. In the current long jump training competitions, most of the long jumps are to set up a bunker on the ground, and place fine sand in the bunker. When the athlete jumps on the fine sand, a bunker will be left. The result of measuring the bunker is the long jump. result. [0003] However, after each long jump, pit marks will be left in the bunker. After multiple long jumps, there wil...
