Cement mixing pile machine positive and negative power box and mixing pile machine

The utility model provides a cement mixing pile machine positive and negative power box. The cement mixing pile machine positive and negative power box comprises at least one set of power device arranged on a #-shaped rack; the power device comprises a driving device, the driving device is connected with a planetary gearbox, a hollow channel is formed in the middle of the planetary gearbox, and a hollow rotating shaft is arranged in the hollow channel. A guniting head is connected to the rotating shaft. The cement mixing pile machine positive and negative power box and a mixing pile machine are simple in structure, the weight of the overall machine is reduced, movement is convenient, and convenience is brought to use. The position of the guniting head is changed, the using rate is improved, and losses are reduced. The guniting head is convenient to disassemble and assemble, maintaining is convenient, damage, caused by abrasion, to the guniting head is avoided, and cost is saved. The rotating shaft in the middle of the planetary gearbox is isolated from a planetary gear through the hollow channel; in the grouting process, mixing can be completed more continuously and smoothly, the using rate is improved, slurry is prevented from entering the planetary gearbox, the repairing rate is reduced, and time and labor are saved.
