Description

Stump excavation machinery head

Technical field:

The utility model relates to a kind of small engineering machinery, specifically a kind of stump excavation machinery head.

Background technology:

At present; the stump cleaning mainly is to excavate by manpower; adopt perhaps that tractor pulls, chemical attack, manually burn; great majority be losing no matter; discarded stub is by its spontaneous corrosion etc., and so not only benefit is low, and also very big to environment damage; the excavation effect is undesirable, is difficult to adapt to new environmental protection requirement.

Summary of the invention:

The purpose of this utility model provides a kind of stump excavation machinery head that adopts mechanical system to excavate discarded stump.

The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of stump excavation machinery head, it comprises suspension bracket, power is installed on the suspension bracket, by the brill tube and the liftout attachment of its drive, the bottom of boring tube is equipped with cutting tip, and the middle and upper part of boring tube is equipped with by the fixing steel wire rope of steel wire rope movable block.

The utility model bores tube when the work under the off plumb situation for making, but automatic shift regulate, shift unit is installed on suspension bracket, power is installed on the shift unit; Described shift unit is the slip cap of two pairs of band sliding axles, and its horizontal sliding axle is connected with suspension bracket, and the longitudinal sliding motion axle is installed on the horizontal slip cap, and power and liftout attachment are installed in longitudinal sliding motion and put.

The utility model has flute for conveniently going out bits on the brill tube, the dust lead bar is installed on the flute.

Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, operation, conveniently moving, and the working efficiency height, little to face of land destruction, the favorable environment protection.

Description of drawings:

Accompanying drawing is a structural representation of the present utility model.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing.

By accompanying drawing as can be known, a kind of stump excavation machinery head, it comprises suspension bracket 6, power is installed, by the brill tube 12 and the liftout attachment of its drive on the suspension bracket 6, its power be hydraulic motor 3 by reduction box 4, reduction box main shaft 16 by adapter sleeve 9 with bore tins 12 and be connected.The bottom of boring tube 12 is equipped with cutting tip 15, and the middle and upper part of boring tube 12 is equipped with the steel wire rope of being fixed by steel wire rope movable block 10 11.

The utility model bores tube 12 when the work under the off plumb situation for making, but automatic shift regulate, on suspension bracket 6, shift unit is installed, power is installed on the shift unit; Described shift unit is the slip cap of two pairs of band sliding axles, and its horizontal sliding axle 18 is connected with suspension bracket 6, and longitudinal sliding motion axle 7 is installed on the horizontal slip cap 17, and power and liftout attachment are installed on the longitudinal sliding motion cover 8.

The utility model has flute 13 for conveniently going out bits on brill tube 12, dust lead bar 14 is installed on the flute 13.

Suspension bracket 6 is fixed on the walking machine through connecting pin 19 by pinboard 5.

During the utility model work, hydraulic motor 3 drives and bores tube 12 rotary cuttings, with stump week root all cut off, when being drilled into the only surplus end of certain depth during root, steel wire rope 11 is boring 12 li in tube with the stump locking, utilize and bore tube 12 turning powers strand root of the disconnected end, propose to bore tube 12 and stump then, liftout attachment is that two joint hydraulic pressure tops 1 are fixed on the hydraulic pressure upper frame 2, and push rod is in reductor main shaft 16, can move up and down, steel wire rope 11 lockings are released at the stump that bores 12 li in tube.Shift unit is when boring tube 12 work under the off plumb situation, but automatic shift is regulated.Flute 13 timely chip removal when boring tube 12 work, two joint hydraulic pressure tops are installed in the casing top, and locking is released at the stump that bores in the tube.

The utility model can be by the steel wire rope movable block 10 convenient steel wire ropes 11 of regulating in the position of boring on the tube 12 according to the stump size.
