Description
Technical field
The present invention relates to sports equipment technical field, specially a kind of reciprocating sports tournament the jumping pit trowelling machine.
Background technology
Sports is also in continuous development while continuous improvement with living standard, wherein being transported in present physical culture
Long-jump is one of essential project in dynamic.Long-jump, also known as running broad jump, track and field sports jump event.By run-up, take-off,
Soar and the combination of actions such as land and form.Sportsman uses monopodia take-off, through rank of soaring along straight line run-up after take-off board frontal line
Section, is then fallen with biped in sand pit, determines ranking with the length jumped during match.Long-jump is one of most ancient athletics event,
Just there is long-jump in ancient Greek's Olympic " pentathlon ".According to Historical Data Data About, the long-jump match of first official is in Christian era
Hold within first 708 years, away from modern existing more than 2700 years history.The facility of long-jump at that time is very simple, simply the soil property on ground
Plane pine, then replaces take-off board above putting a threshold.To produce injury accident when avoiding landing, instead of later with sand pit
Loosen the soil.18 end of the centurys, ancient special wooden this of French education man are classified as long-jump one of big event taken exercises with Yaan, and at him
Works in describe the equipment and training method of jigging separation in detail, highly affirmed that long-jump is important in human motion
Effect.Propulsion over time, the record of jigging separation are constantly broken.In modern age track and field events, on the books first
Men's long jump world record is that British Movement person Mai Qieer created in 1864, and achievement is 5.48 meters.Than covering in the 19th Austria
The new record of rice is broken.Across activities such as streams when the long-jump mankind hunt or escaped wild beast, afterwards as the means of military training.
Long-jump is all to set a sand pit on the ground mostly in present long-jump training and competition, is placed in sand pit thin
Sand, it will not also be made so as to jump the measurement for the result that can be played on fine sand as people, and jump on fine sand to sportsman
Into any injury, but often jump once can all leave hole print on fine sand, so as to just needs being flattened to fine sand repeatedly
Work, so as to further add workload.So sports tournament the jumping pit needs to be polished with trowelling machine.
But present sports tournament the jumping pit trowelling machine, it can not carry out floating when in use, but can hinder
Hindering user's long-jump so that sportsman can ram, and cause sand pit trowelling machine to be inconvenient to use, while floating when,
