Abstract
A forehead for a rotary excavating mast comprises a mast, a forehead, an oil cylinder and a pin shaft. The oil cylinder is connected between the middle of the mast and the lower portion of the forehead, and a contact position between the mast and the forehead is fixed through the pin shaft. The forehead for the rotary excavating mast is simple in structure and convenient to use.
Description
Technical field
The utility model relates to machine components, is specially to be used to revolve the forehead that digs on the mast.
Background technology
At present, mostly what revolve the forehead that digs on the mast is fixed, can not be voluntarily according to the purpose of operation task; Regulate the drift angle of forehead and the position of forehead voluntarily, must could adjust forehead, like this when practical operation by means of the external force effect; Trouble has very been brought very big inconvenience to work.
The utility model content
The technical problem that the utility model solved is to be provided for revolving the forehead that digs on the mast, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
Be used to revolve the forehead that digs on the mast, comprise mast, forehead, oil cylinder, bearing pin, be connected with oil cylinder between said mast middle part and the forehead bottom, the contact position of said mast and forehead is fixed with bearing pin.
Beneficial effect
The utility model is simple in structure, and is easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1; Be used to revolve the structural representation that digs the forehead on the mast, be used to revolve the forehead that digs on the mast, comprise mast 1, forehead 2, oil cylinder 3, bearing pin 4; Be connected with oil cylinder 3 between said mast 1 middle part and forehead 2 bottoms, said mast 1 is fixing with bearing pin 4 with the contact position of forehead 2.
During use; When needs adjustment forehead 2; Thereby the garden of forehead 2 bottoms and oil cylinder 3 junctions dish can rotate the pressure of hydraulic pressure in the adjustment oil cylinder 3; Thereby the relative angle of adjustment mast 1 and bearing pin 4, bearing pin 4 cooperates the rotation of forehead 2 simultaneously and does corresponding rotation, thereby reaches the purpose through self adjusting angle.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model; The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
