The utility model has the advantages that it is simple in structure, it is easy to use, mitigate worker's piling labor intensity, production efficiency is high.
In this product, the piling machine includes stake chamber, pick body, base, and the stake chamber is arranged on base position；Stake chamber open at its lower end
And opening is sentenced positioned at base bottom face and houses body to be driven piles；When piling, the pressure oil below flow cylinder inner carrier is through oil circuit
Imported by hydraulic valve above piston, move down piston and promote the pile crown of impact anvil driven pile intracavitary, when piston is displaced downwardly to downlink
During range, oil circuit off-load makes the flow barrel chamber body above pressure oil quick backflow to piston, piston is moved up reset；Due to
Product, which carries a chamber, can be placed on the top of body to be driven piles, therefore piling machine can be made directly to be nested with and be fixed on stake top and drive piles,
So that piling machine keeps holding position in pile crown, it is not easy because the reaction force of piling makes equipment come off or train off, improves and beat
Stake efficiency.
