Abstract
The utility model discloses a rotation blockage preventing jaw of a six-jaw grab bucket, and belongs to the professional and technical field of maintenance machinery. The jaw comprises a jaw body, a rotating shaft and a holder, a shaft sheath is fixedly arranged at the upper end of the jaw body, the rotating shaft penetrates the shaft sheath, and two ends of the rotating shaft are fixed on the holder. The jaw is characterized by further comprising a scraper fixed on the shaft sheath, the plane on which the scraper is located is perpendicular to a straight line on which a central axis of the shaft sheath is located, the scraper is trapezoidal, and a plurality of tooth-shaped protrusions are arranged on two side faces of the scraper. Compared with the prior art, the jaw has the advantages of simple structure, convenience in use, reduction of maintenance cost and high reliability.
Description
Technical field
The utility model relates to a kind of jaw lobe of six lobe grab buckets, particularly a kind of six lobe grab bucket jaw lobes that prevent that convolution from blocking.
Background technology
At present, the handling of nickel minerals have generally been grabbed bucket by six lobe disc types, and because nickel minerals self has certain viscosity, six lobe disc type grab buckets are when handling nickel minerals, and a large amount of nickel minerals can stick to jaw lobe axis of revolution place, cause the revolution of grab bucket jaw to be stopped up.
In the process opening and closing in grab bucket, due to the existence of nickel minerals, cause jaw lobe to rotate difficulty, affect work efficiency.Add the rigid strength of nickel minerals self, easily cause the problems such as fracture, flange distortion of wearing and tearing, jaw lobe axis of revolution and the axle sheath of jaw lobe axis of revolution, affect the safety that six lobe disc types grab buckets are used.
Utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, and a kind of six lobe grab bucket jaw lobes that prevent that convolution from blocking are provided.
The technical scheme in the invention for solving the technical problem is: a kind of six lobe grab bucket jaw lobes that prevent that convolution from blocking, comprise jaw lobe body, axis of revolution and fixed mount, described jaw lobe body upper end is fixed with axle sheath, and axis of revolution is through axle sheath, and two ends are fixed on fixed mount; It is characterized in that: also comprise scraper plate, described scraper plate is fixed on axle sheath, the plane at scraper plate place is vertical with axle sheath center shaft place straight line, and described scraper plate is trapezoidal, is equipped with a plurality of detent projection on scraper plate two sides.
Above-mentioned scraper plate cross-sectional plane is fusiformis.
On above-mentioned scraper plate, be also fixed with two wing plates, one end of described two wing plates is fixedly connected with the upper end of two sides of scraper plate respectively, described wing plate and scraper plate side angle <90 °.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, simple in structure, easy to use, reduced maintenance cost.
2, trapezoidal or fusiformis scraper plate can easier break the nickel minerals integral body sticking between axis of revolution, axle sheath and fixed mount by its structural wedge angle, detent projection on scraper plate side, nickel minerals integral body is broken into polylith, easily nickel minerals is removed clean, prevent that in work, the problems such as the fracture of axle sheath, flange distortion and jaw lobe axis of revolution severe wear that cause are stopped up in the revolution of jaw lobe, greatly improved the safety that six lobe disc type grab buckets are used.

Fig. 1 is the structural representation of jaw lobe of the present utility model and axis of revolution.
Fig. 2 is the sectional structure schematic diagram of jaw lobe of the present utility model and axis of revolution annexation.
Fig. 3 is the structure for amplifying schematic diagram of A in Fig. 2.
Fig. 4 is the side-looking structural representation of the utility model middle scraper.
The specific embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, 2, in embodiment 1, the utility model comprises jaw lobe body 1, axis of revolution 2, fixed mount 3 and scraper plate 4.
As shown in Figure 2, described jaw lobe body 1 upper end is fixed with axle sheath 5, and axis of revolution 2 is through axle sheath 5, and two ends are fixed on fixed mount 3.
As shown in Figure 3, described scraper plate 4 is fixed on axle sheath 5, and the plane at scraper plate 4 places is vertical with axle sheath 5 center shaft place straight lines, and described scraper plate 4 is trapezoidal, and scraper plate is equipped with a plurality of detent projection on 4 two sides.In prioritization scheme, described scraper plate 4 cross-sectional planes are fusiformis, and its object is to break the nickel minerals powder ball sticking.
Scraper plate 4 can easier break the nickel minerals powder ball integral body sticking between axis of revolution 2, axle sheath 5 and fixed mount 3 by its structural wedge angle, add the detent projection on scraper plate 4 sides, nickel minerals powder ball integral body is broken into polylith, easily nickel minerals is removed clean, prevent that in work, the problems such as 5 fractures of axle sheath, flange distortion and jaw lobe axis of revolution 2 severe wears that cause are stopped up in the revolution of jaw lobe, greatly improved the safety that six lobe disc type grab buckets are used.
In order better to adapt to need of work, in embodiment 2, as shown in Figure 4, on described scraper plate 4, be also fixed with two wing plates 6, one end of described two wing plates 6 is fixedly connected with the upper end of two sides of scraper plate 4 respectively.Described wing plate 6 and scraper plate 4 side angle <90 °.By wing plate 6, can realize the application of force in nickel minerals powder ball multiple directions, accelerate breaking of nickel minerals powder ball.
It should be noted that; particular of the present utility model have been described in detail the utility model; for a person skilled in the art, the various apparent change of in the situation that not deviating from spirit and scope of the present utility model, it being carried out is all within protection domain of the present utility model.
