Abstract
The utility model discloses an impact frame adjusting and fixing device of an impact crusher; the impact frame adjusting and fixing device comprises a hanging plate, a press plate, a back plate, a spring, a pull rod, a spring seat and a screw rod, wherein the hanging plate sticks to the press plate; equally spaced circular pull rod holes are formed in the hanging plate and the press plate, wherein screw rod pressing cylinders and screw rod holes are respectively formed on the press plate and the back plate; distances among the screw rod pressing cylinders and distances among the screw rod holes are less than those among the circular pull rod holes on the hanging plate and the press plate; spring recesses are formed on the surroundings of the screw rod holes on the back plate; a cap head with diameter of larger than the diameters of the screw rod pressing cylinders is arranged at the end part of the screw rod; a spring is sleeved on the screw rod and fixed on the screw rod by a spring seat; and the pull rod is fixed between the hanging plate and the back plate by a special nut; and according to the utility model, the spring on the fixing device can be effectively protected against being damaged due to impact of stones, so that normal production is ensured, the working efficiency is increased and consumption of spare parts of the crusher is reduced; in addition, the impact frame adjusting and fixing device of the impact crusher, disclosed by the utility model, has the advantages of simple structure and convenience for mounting and maintenance and can be used for saving time and cost.
Description
Technical field
The utility model relates to a kind of grinder hammerhead, belongs to the plant equipment field, particularly a kind of impact rack regulation fixing apparatus of impact crusher.
Background technology
Fine crusher is widely used in the industries such as chemical industry, building materials, metallurgy, mining, coal separation, sand processed and refractory material at present, and tup is one of direct parts that contact with material of fine crusher, therefore the tup frequency of utilization of fine crusher is high, this just so that the fine crusher hammer head life-span is very short, needs often will change; All there are the very low shortcoming of hammer head material utilization rate in the structure that tup is fixing and the structure of monolateral strike, and particularly the tup scope of attack is too thin, and set bolt exposes, and easy generation fault during use increases maintenance cost, affect the long-term safety operation of equipment.
The utility model content
Technical assignment of the present utility model is the impact rack regulation fixing apparatus that a kind of impact crusher is provided for above prior art deficiency.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of impact rack regulation fixing apparatus of impact crusher, comprise link plate, pressing plate, rear plate, spring, pull bar, spring base and screw mandrel, described link plate and pressing plate are close together, and described link plate and pressing plate are provided with equidistant circular tie rod hole, be respectively equipped with distance on wherein said pressing plate and the rear plate less than screw mandrel pressure cylinder and the screw hole of the distance of the circular tie rod hole on link plate and the pressing plate, have spring groove around the screw hole on the described rear plate, described screw mandrel end is provided with diameter greater than the cap head of screw mandrel pressure cylinder diameter, cover has spring and is fixed on the screw mandrel by spring base on the described screw mandrel, and described pull bar is fixed between link plate and the rear plate by special nut.
Described spring base and screw mandrel hold-down nut are welded as a whole.
Described screw mandrel and pull bar end are provided with protective sleeve.
This utility model can effectively be protected the spring on the fixture can not produce because of the impact of building stones and damage, thereby guarantees normal production, increases work efficiency, and reduces the consumption of disintegrating machine spare part; This utility model is simple in structure in addition, and I﹠M is convenient, can save time and cost.
