Specific embodiment
In order to make the above-mentioned features and advantages of the utility model more obvious and understandable, special embodiment below, and cooperate attached drawing,
It is described in detail below.
As shown in Fig. 1 ~ 3, a kind of mountainous region forest land working rig, it is characterised in that: include a welded pipe 1, the welded pipe
Upper end is connected with a hydraulic motor 2 for rotating it, and the welded pipe is axially installed with screw blade 3 along it in the shape of a spiral,
The screw blade is equipped with blade 4 far from the end surface of hydraulic motor, and it is directed downwardly that the welding bottom of the tube is installed with tip
Conical drill bit 5, the cone drill bit is lower compared with the horizontal position of blade, convenient for navigating to the center in hole when digging pit
Position, and when tip cone directed downwardly makes drill down, is more laborsaving.
In the utility model embodiment, the output shaft 6 of the hydraulic motor is connected with the upper connecting shaft 7 of one speed reducer
It connects, the lower connecting shaft 8 of the retarder is connected with the axis hole in welded pipe, and key 9, the axis are installed in the lower connecting shaft
The keyway 10 for key insertion is equipped with inside hole, and the welded pipe and the lower connecting shaft same level position are equipped with pin hole 11,
Split pin 12 is inserted on pin hole in welded pipe and lower connecting shaft.
In the utility model embodiment, the retarder and welded pipe joining place are equipped with a damper 13, the damping
Device includes protective shell 14 that is coaxial with the welded pipe and being looped around outside it, is equipped with a spring 15, the bullet in the protective shell
Spring is set in welding tube outer surface, the spring upper end and upper surface apical grafting in damper, and the welded pipe in the protective shell is same
Axis is installed with a resilient cushion 16, lower spring end and resilient cushion upper surface apical grafting, and the retarder and damper pass through bolt
17 connection, in the specific use process, conical bit contact arrive hard soil block when, working rig generate acutely shakes, due to
Welded pipe and split pin are clearance fits, and concussion will have micro-displacement over time, and gap becomes larger, and make welded pipe under
Connection between centers bears immense pressure in vertical direction generates relative displacement, and after having damper, when generating acutely concussion, because
Damper is connected with retarder, and resilient cushion is installed in welded pipe, spring can effectively crust deformation with compensate concussion generate between
Gap, so that solving the problems, such as that welded pipe and lower connecting shaft generate to loosen influences to work normally.
In the utility model embodiment, the screw blade includes single screw blade or more spiral shells according to its shape
Rotating blade requires the helical blade that can choose different lead according to different digging pit, and stability is strong, and size is small, passability
Good, it is convenient to mount, and improves workpiece service life, improves the efficiency of digging pit of working rig, also weighs to overall structure and want shadow
It rings.
