Description

Sandpit arranging device

Technical Field

The invention relates to the technical field of sports equipment, in particular to a sand pit arranging device.

Background

Jumping of a sand pit is a common sports game item, in order to ensure the safety of players and improve the game speed, the softness of the sand pit needs to be ensured, a pit print is left in the sand pit every time of jumping, sand in the pit print becomes hard, splashed sand usually falls in front of and on the left side and the right side of the pit print, therefore, the sand pit needs to be leveled repeatedly, the manual sand leveling rake is usually adopted for leveling, the leveling speed is slow, the low leveling degree of the sand pit is easy to appear, a guide rail is fixedly arranged at the edge of the sand pit, the sand pit leveling machine directionally moves along the guide rail to finish the leveling of the sand pit, this kind of sand pit levelling machine is the reciprocal arrangement of single fore-and-aft direction usually, perhaps the reciprocal arrangement of direction about single, and the arrangement area is great, can not only carry out arrangement work to the hole seal as required, can not arrange in order the sand that 3 side spilt at least to the hole seal simultaneously, improves work efficiency.

CN107648832A discloses a long jump sandpit trowelling machine for reciprocating sports competitions, which is characterized in that a sand trowelling mechanism capable of reciprocating up and down is arranged above a jumping board in order to avoid influencing the psychology of long jump persons and causing collision danger in case that the sandpit trowelling machine crosses the sandpit and the long jump persons, and the sand trowelling mechanism still crosses the sandpit and has certain influence on long jumps requiring running assistance, jumping, emptying and other actions; along with the back-and-forth movement of the sand smearing mechanism, the sand leveling plate moves left and right in a reciprocating mode to finish sand pit leveling, the sand leveling device is not provided with a pit printing sand loosening mechanism, sand loosening cannot be performed on hardened sand, sand splashing out of the front of a pit print cannot be effectively returned to the pit print through the left and right reciprocating movement of the sand leveling plate, and therefore the flatness of the whole sand pit is guaranteed.

CN109646931A discloses an automatic floating and finishing device for a long jump match sandpit, which can loosen and level the sandpit, but also perform left-right reciprocating finishing to splash the sand in front of the sandpit mark, and can not effectively return the sand to the sandpit mark, thereby ensuring the flatness of the whole sandpit.

The device is fixedly installed at the edge of the sandpit, namely the sandpit and the sorting device are fixedly installed in a one-to-one correspondence mode, if a plurality of long jump sandpits are arranged, the corresponding sorting devices are required to be installed, and the cost of the floating of the sandpits is improved.
