According to the technical scheme of the fixing structure for the rotary screen frame, the cones of the bolts are inserted in the conic concave holes of the screen frame body, so that the screen frame body is well fixed; under the action of the bolts, the screen frame body and the screen body are connected into a whole; according to the conic contact faces, the bolts and the screen frame body are effectively fixed and bolt looseness caused by vibration is effectively prevented; the cones are inserted into and matched with the screen frame body, the cones and the conic concave holes have the locating function, so that installation flatness of the screen frame body is guaranteed, synchronous operation of the screen frame body and the screen body is achieved, collision is avoided, operation noise of a cleaning device is reduced, and the service life of the screen is prolonged.
Description
Technical field
The utility model relates to a kind of feed-processing equipment, especially relates to a kind of fixed structure that turns round the revolution screen frame of classifying screen.
Background technology
In current feed processing technology, in order to guarantee that feed quality and equipment normally move, must clear up raw material, to remove various foreign material, dust and fibrous substance.The working method of cleaning equipment is vibration, revolution, selection by winnowing etc.What at feed factory, often use is vibration and two kinds of modes of revolution, and most of cleaning equipment utilizes screen cloth as classification parts, and screen cloth is in the majority with woven screen again from manufacturing process and cost consideration.Woven screen is first fixed on screen frame conventionally, and screen frame adopts harder weedtree manufacture conventionally.By screen frame, in being fixed on the sieve nest of equipment, sieve nest is a rectangular frame, and upper and lower faces is open, below surrounding be provided with the gripper shoe that holds up screen frame.Screen frame can be taken out replacing and the maintenance of being convenient to screen cloth from sieve nest like this.Sieve nest carries out gyration under dynamic action, the motion of drive screen frame, material is along with revolution travels forward on screen cloth face, and in motion process, screen cloth face is divided into oversize and screenings by material, for the difference of material, use the screen cloth of different meshes, realize the separated of material and impurity.
Screen frame and sieve nest fixed structure are at present: screen frame is placed in sieve nest gripper shoe, and withstand with bolt two ends of screen frame, and the nut of bolt is fixed on sieve nest.This fixed form usually breaks down when actual motion, and because screen frame is that to hold out against what adopt with bolt on sieve nest be hard contact, and contact-making surface is plane.Bolt looseness or screen frame are fixing uneven, and when sieve nest gyration, screen frame motion a little lags behind, and occurs clashing into sieve nest, produces sound, and the time has been grown screen frame collision deformation and loose, and equipment cannot normally move.Screen frame is had relatively high expectations to the timber using simultaneously, should have certain hardness, also wants certain flatness, and cost is higher like this.
Summary of the invention
The purpose of this utility model is the deficiency existing for prior art, and a kind of fixed structure that turns round screen frame is provided, and avoids screen frame in motion process, to clash into sieve nest, avoids bolt looseness.
For achieving the above object, the technical scheme that the fixed structure of the utility model revolution screen frame adopts is: a kind of fixed structure that turns round screen frame, comprise sieve nest and screen frame, described screen frame is provided with screen cloth, described screen frame is arranged on sieve nest inside, the two ends of described sieve nest are provided with the bolt being threaded, and the end of described bolt is provided with cone, and the two ends of screen frame are provided with the taper shrinkage pool coordinating with cone.The cone of bolt is inserted the taper shrinkage pool of screen frame, better fixed screen frame, under bolt active force, make screen frame be connected with sieve nest as a whole, conical contact face has effectively been fixed bolt and screen frame, effectively prevented because vibrate the bolt looseness causing, and cone is inserted cooperation, cone projection has positioning action with taper shrinkage pool, guaranteed that screen frame installation is smooth, reduced the operating noise of cleaning equipment, the service life of having improved screen cloth.
Described cone arranged outside has thread protrusion.Thread protrusion can produce and better to coordinate with taper shrinkage pool under the effect of extruding force, better fixing screen frame.
Described thread protrusion is elastomer.Thread protrusion is elastomer, can adopt the plastics such as rubber, resin to make, and elastomer has certain strain, can make cone better be fastened on the inner side of taper shrinkage pool, and elastomer is full of gap, produces interference fit.
Described cone is flexible cone.Flexible cone is inserted taper shrinkage pool, under the effect of bolt extruding force, produces strain, and flexible cone is full of gap and produces interference fit, has improved the binding strength of screen frame and sieve nest.
Described flexible cone arranged outside has thread protrusion.Thread protrusion can be that elastomer can be also inelastic body, has improved the tight ness rating of cone and taper shrinkage pool, has guaranteed the stable bond of screen frame and sieve nest.
Described flexible cone is rubber bodies.Flexible cone can also adopt resin etc. to have flexible material and make.
Described sieve nest is provided with nut, and described bolts and nuts are threaded, and described nut is fixed by mount pad and sieve nest.By mount pad hold-down nut, improved the fastness of nut and sieve nest, guaranteed the stability that is threaded of bolt with sieve nest.
The utility model compared with prior art, has the following advantages:
The cone of bolt is inserted the taper shrinkage pool of screen frame, better fixed screen frame, under bolt active force, make screen frame be connected with sieve nest as a whole, conical contact face has effectively been fixed bolt and screen frame, effectively prevented because the bolt looseness that vibration causes, and cone is inserted and is coordinated, cone projection has positioning action with taper shrinkage pool, guaranteed that screen frame installation is smooth, screen frame and sieve nest synchronous operation, avoided collision, reduced the operating noise of cleaning equipment, improved the service life of screen cloth, adopt the fixed structure of this revolution screen frame, the material of reduction screen frame that can be suitable, reduced production cost.
