Detailed Description

The utility model provides a high-efficient stake machine of digging trees, its includes main part 2, connecting plate 12, drum 6, slewing bearing 3 and ejection mechanism, slewing bearing includes inner circle and outer lane, inner circle and main part fixed connection, can make things convenient for the dismouting through bolt fixed connection between inner circle and the main part, also can adopt other fixed connection, and the outer lane is rotated by the drive of slewing drive mechanism 10.

The connecting plate is arranged below the slewing bearing and fixedly connected with the outer ring, and when the slewing bearing is implemented specifically, the connecting plate and the outer ring can be fixedly connected through bolts, so that the slewing bearing is convenient to disassemble and assemble, and other fixed connections can be adopted.

The cylinder is fixedly arranged on the connecting plate and the outer wall of the cylinder is fixedly provided with the spiral teeth 7, and particularly, the connecting plate and the cylinder can be fixedly connected through bolts, so that the cylinder is convenient to disassemble and assemble, and other fixed connections can be adopted. Can make things convenient for the dismouting of helical tooth to change through welded fastening between helical tooth and the drum, also can adopt integrated into one piece's mode fixed, be convenient for the preparation and increase the work solidity between the two, prevent that the helical tooth from droing.

The ejection mechanism comprises an ejection driving device 11 and an ejection plate 8, and the ejection plate is arranged in the cylinder and driven by the ejection driving device to reciprocate up and down in the cylinder.

Preferably, the rotation driving mechanism is hydraulic rotation driving, a driving gear 9 is sleeved on a rotating shaft of the hydraulic rotation driving, and external teeth (not shown) meshed with the driving gear are arranged on an outer ring of the rotation support. The hydraulic slewing drive can be directly connected with a hydraulic system of the excavator, the hydraulic system of the excavator drives the rotating shaft of the hydraulic slewing drive to rotate, and therefore the outer ring of the slewing bearing is driven to rotate through meshing of the driving gear and the outer teeth on the outer ring of the slewing bearing.

Further, the lower end of the outer wall of the cylinder is fixedly provided with an inserting tooth 5. The inserting teeth facilitate the cylinder to be quickly inserted into soil, so that the digging efficiency is improved, and the cylinder is protected from being damaged. The inserting teeth can be integrally formed with the cylinder, so that the manufacturing is facilitated, the firmness of connection between the inserting teeth and the cylinder is improved, the inserting teeth are prevented from falling off, fixed connection modes such as clamping, riveting or bolt connection can be adopted, and the inserting teeth are convenient to replace after being damaged.

Furthermore, a plurality of ejecting teeth 4 are fixedly arranged on the lower surface of the ejecting plate, so that the stumps can be conveniently ejected out of the cylinder.

Preferably, the ejection driving device is a hydraulic oil cylinder, the hydraulic oil cylinder is fixedly arranged on the inner ring of the slewing bearing, and a piston rod of the hydraulic oil cylinder penetrates through the inner ring of the slewing bearing, the connecting plate and the cylinder and then the lower end of the piston rod is fixedly connected with the ejection plate.
