Description
Technical field
The utility model relates to a kind of oil drilling equipment, and oscillating screen inclination angle stepless regulator especially belongs to the technical field of bolting machinery.
Background technology
At present, the oscillating screen inclination angle is generally fixed, and each vibratory sieve has a screen angle, so be very difficult when regulating the oscillating screen inclination angle.Therefore when material is carried out screening operation, the shared ratio of the water content of material, various granule materials, the kind of material, different operating mode all need different screen angles, and fixing screen angle is difficult to adapt to the needs of material screening.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, the oscillating screen inclination-angle regulating device that a kind of simple in structure, easy to adjust, with low cost, applicability is strong, can realize step-less adjustment is provided, and the utility model can solve the impact that the factor such as ground out-of-flatness is regulated screen angle.
The purpose of this utility model is achieved through the following technical solutions: oscillating screen inclination angle stepless regulator, involving vibrations sieve base, the screen box that is arranged on vibratory sieve base top, setting are connected to the adjustment frame of screen box both sides, it is characterized in that, described vibratory sieve base left-right symmetry position is respectively equipped with four-bar mechanism, described four-bar mechanism is rhombus, be hinged between four bars of four-bar mechanism, place, upper and lower two diagonal angles of four-bar mechanism respectively with adjust frame, the vibratory sieve base is hinged; The horizontal diagonal of four-bar mechanism is provided with the adjusting screw mandrel, and screw mandrel one end is connected with the four-bar mechanism hinged place, and the other end and four-bar mechanism hinged place are fixing by the nut location.
Described adjustment frame is connected with screen box by damping block.
Be provided with spring between described screen box and the vibratory sieve base.
Spring between screen box of the present utility model and the vibratory sieve base has two effects: the one, help the return of mechanism; The 2nd, can vibration damping when equipment is worked, be conducive to improve the efficient of oscillating screen tilt adjustment, can also prolong the service life of vibratory sieve.The lower end of four-bar mechanism (place, diagonal angle) is hinged on the vibratory sieve base, upper end (place, diagonal angle) is hinged with the adjustment frame, and be arranged symmetrically with, horizontal direction (place, left and right diagonal angle) is provided with screw mandrel, the hole that screw mandrel passes the bearing of a four-bar mechanism left side (right side) end place, diagonal angle setting connects the location by nut, and screw mandrel one end and place, four-bar mechanism right(left)end diagonal angle are welded and fixed.Making four-bar mechanism realize rising by the nut on the rotary screw opens and shrinks, thereby reach the purpose that screen angle is regulated, to satisfy different operating modes to the requirement of screen angle, adjust relatively more conveniently, can adjust according to the material screening needs of reality the size of screen angle.Simultaneously, both sides independently four bar elevation and subsidence regulating devices can change arbitrarily according to different operating modes the height of one of them four-bar mechanism, can solve the ground out-of-flatness to the impact that vibratory sieve produces, and have greatly reduced the requirement of equipment to operating mode.In addition, damping block is housed, the vibration of base when working with minimizing equipment between screen box and the adjustment frame.The utlity model has simple in structure, easy to adjust, strong adaptability, characteristics with low cost can realize step-less adjustment, prolong the service life of vibratory sieve, can be widely used on the vibratory sieve of various materials.

The specific embodiment
Be further described below in conjunction with accompanying drawing 1,2 pairs of the utility model.
Oscillating screen inclination angle stepless regulator, involving vibrations sieve base 1, the screen box 9 that is arranged on vibratory sieve base top, screw mandrel 6, adjustment frame 7.Adjusting frame is connected with screen box by damping block 8.Be provided with the spring 2 for return and vibration damping between screen box and the vibratory sieve base, spring links to each other with the vibratory sieve base.
Vibratory sieve base left-right symmetry position is respectively equipped with four-bar mechanism 3, and four-bar mechanism is rhombus, be hinged between four bars of four-bar mechanism, place, upper and lower two diagonal angles of four-bar mechanism respectively with adjust frame, the vibratory sieve base is hinged.
Four-bar mechanism is fixed on the vibratory sieve base, the four-bar mechanism horizontal direction of two symmetry arrangement (place, left and right diagonal angle) is provided with screw mandrel, the junction at an angle in two diagonal angles of four-bar mechanism horizontal direction is provided with the bearing with centre bore, two connecting rods of four-bar mechanism are articulated and connected with bearing respectively, and screw mandrel one end passes centre bore and is fixedly connected with the junction at another angle.Screw mandrel is spacing fixing with centre bore by nut 4, spring washer 5.The utility model in use, come the nut 4 adjusting screw mandrel left and right directions on the rotary screw 6 to move according to operating mode, the motion of screw mandrel has driven the variation of four-bar mechanism 3 whole heights, thereby suitable adjustment is carried out at the oscillating screen inclination angle, makes vibratory sieve reach maximum screening effect.This device solves the problem that can not adjust of the screen angle of vibratory sieve.
