Description

Reciprocating type sports match long jump sand pit trowelling machine

Technical Field

The invention relates to the technical field of sports equipment, in particular to a reciprocating type sports match long jump sand pit trowelling machine.

Background

With the continuous improvement of living standard, sports industry is also continuously developing, wherein long jump is one of indispensable projects in the current sports. Long jump, also known as rapid jump, track and field sports jump project. Is formed by combining the actions of running, starting, emptying, landing and the like. The athlete runs along a straight line, jumps with a single foot before and after the jump board, goes through the vacation stage, then falls down in a sandpit with double feet, and determines the ranking with the jump distance during the competition. Long jump is one of the oldest sports, with long jump in the "five sports" of the ancient greek olympic. The history states that the first formal long jump game was held 708 years before the official meta, and has been 2700 years old. The facility of long jump at that time is very simple, just dig loose the soil texture of the ground, then put a threshold in front instead of the springboard. In order to avoid injury accidents during landing, a sandpit is used for replacing the loose soil later. At the end of the 18 th century, the french education Gu Temu s and yaan listed long-jump as one of the important physical exercises, and described in their works in detail the equipment and training methods for long-jump exercise, highly confirming the important role of long-jump in human exercise. With the advancement of time, the record of the long jump movement is continuously broken. In recent track and field games, the first recorded record of the world for a man's long jump was created by the uk athlete, mackerel, in 1864, with a score of 5.48 meters. The beamond breaks up in the new record at the 19 th time of Omi. The long jump human being can cross the river channel when hunting or evading wild animals, and the like, and then becomes a military training means.

In the existing long jump training competition, a sand pit is arranged on the ground, and fine sand is placed in the sand pit, so that when people jump on the fine sand, competition results can be measured, and the player cannot be injured by jumping on the fine sand, but each jump leaves a pit mark on the fine sand, so that the fine sand needs to be repeatedly leveled, and the workload is further increased. So the sports long jump pit needs to be ground down by a trowelling machine.

But present sports match long jump sand pit trowelling machine, it can not carry out trowelling when using, but can hinder the user long jump for the sportsman can hit the head, and makes sand pit trowelling machine inconvenient use, and simultaneously when trowelling, also inhomogeneous, leak the outside of sand pit easily, influence user's use.
