Description
Technical field
The utility model relates to a kind of tumbler, especially a kind of paleocinetic tumbler of screen frame being applicable to automatic turning sieve bend.
Background technology
Automatic turning sieve bend is mainly used in dehydration, the de-mediated operation of coal preparation plant's wet coal preparation, sieve bend in working order under, screen box bottom surface and level are 45-60 ° of inclination angle, slip tangentially feeds compass screen surface by feed box from top with certain speed, due to the effect of centrifugal force, make feed pulp layer be close to compass screen surface motion, flow in the process of another root grating at feed pulp layer by a grating of laterally arranging, the arris of every root grating all produces dissection to feed pulp layer.
Find in actual use, grating in use for some time, seamed edge facing to pulp flow supplied materials direction can wear into fillet because of wearing and tearing, Cut size is caused to diminish, disposal ability declines, because grating has symmetrical section, and can after seamed edge wearing and tearing, grating is oppositely installed, uses another seamed edge.Continuing in the process used, due to the wearing and tearing on sieve bend surface, the seamed edge having worn into fillet can be ground into the sharp edge the same with new grating on the contrary, and therefore, grating can oppositely be installed and used repeatedly, and Cut size all can be kept substantially constant.
At present, the operation that sieve bend is rotated mainly still relies on manpower, rotating operation wherein comprises screen frame is turn to horizontal level from 45-60 ° of angled state, then screen frame is rotated 180 °, after completing rotation, then sieve bend reverse flip made in its using state recovering 45-60 ° of inclination angle by manpower, whole operating process is all come by manpower, both wasted time and energy, reliably dangerous again.
Although occurred utilizing plant equipment to complete the structure of rotation, but the existing mechanism that can realize rotating is generally motor-operated gear drive, belt transmission, Worm Wheel System etc., not only complex structure, equipment volume is large, and in rotation process, and easily there is mechanical damage or error, fault rate is higher in actual applications, although save manpower, be increased maintenance capacity, affect production efficiency.
Utility model content
The utility model is the technological deficiency existed for the existing rotating machinery mentioned in background technology, provides a kind of structure simple, failure rate is low, easy to operate, the tumbler of the automatic turning sieve bend that cost ineffective rate is high.
The technical scheme realizing the employing of foregoing invention object is: a kind of tumbler of automatic turning sieve bend, comprises base, also comprises rotating mechanism and switching mechanism;
Described rotating mechanism comprises bearer bar, oscillating cylinder and rotating disk, and bearer bar is fixedly mounted on the bottom of sieve bend screen frame by connector, and rotating disk and oscillating cylinder are arranged on bearer bar inside; Rotating disk is fixedly connected with bottom screen frame, and oscillating cylinder is connected with rotating disk;
Described switching mechanism comprises jacking cylinder, and jacking cylinder is arranged on base side; The piston rod of this jacking cylinder is connected with described bearer bar plate outer side limit;
Described base is provided with limit switch.
Rotating disk in rotating mechanism with between oscillating cylinder for being flexibly connected, oscillating cylinder drive turntable rotation.
The free end of the piston rod of the jacking cylinder in switching mechanism and the plate outer side limit of bearer bar hinged, bearer bar and base top hinged, jacking cylinder piston rod drive bearer bar upset.
Chassis outer side face is provided with safe cushion block.
The utility model is on the basis used manpower and material resources sparingly, and structure is simple, easy to operate, and rotate flexibly, the tumbler that controllability is strong, this equipment safety is reliable, and stability is strong, failure rate is low, the operating efficiency of great raising equipment, reduces labour intensity.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the syndeton schematic diagram of oscillating cylinder and rotating disk in the utility model.
In figure: screen frame 1, rotating disk 2, bearer bar 3, oscillating cylinder 4, jacking cylinder 5, base 6, limit switch 7, safe cushion block 8.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
See accompanying drawing 1-2, the tumbler of this automatic turning sieve bend disclosed in the utility model, comprises base, rotating mechanism and switching mechanism, and base bottom is a rectangular structure, and its side, top is plane, and opposite side is protruding trapezium structure.
Rotating mechanism comprises bearer bar 3, oscillating cylinder 4 and rotating disk 2, and it is inner that rotating disk 2 and oscillating cylinder 4 are arranged on bearer bar 3.Bearer bar 3 is a frame structure, and its side is fixedly mounted on the bottom of sieve bend screen frame 1 by connector.Rotating disk 2 is fixedly connected with bottom screen frame 1, and oscillating cylinder 4 is connected with rotating disk 2, and oscillating cylinder 4 is fixedly connected with the base plate of bearer bar.
Switching mechanism comprises jacking cylinder 5, and jacking cylinder 5 is arranged on a side of base 6.The piston rod of jacking cylinder 5 is connected with the outer side edges of bearer bar 3 base plate.The side of bearer bar 3 is hinged by the side of the trapezium structure on the tumblers such as bearing pin and base top.
Base is provided with limit switch 7, limit switch is arranged on starting point and the terminal of the rotary movement of screen frame respectively, and the starting point of spinning movement and terminal, is used for playing position-limiting action to the rotation of screen frame, realizes screen frame and puts in place and namely stop.Each limit switch is connected with the electric control gear of control cylinder action respectively, and after screen frame turns to assigned address, limit switch is by signal transmission to electric control gear, and electric control gear controls respective cylinder and stops action.After screen frame upset, the chassis outer side face that screen frame is adjacent with base is provided with safe cushion block 8, and multiple safe cushion block is evenly arranged along base length direction.This safe cushion block for the protection of screen frame, avoid limit switch lost efficacy after, the collision of screen frame and base.
Rotating disk 2 in rotating mechanism with between oscillating cylinder 4 for being flexibly connected, oscillating cylinder 4 drives rotating disk 2 to rotate, thus realizes 180 ° of rotations of screen frame.The free end of the piston rod of the jacking cylinder 5 in switching mechanism and the plate outer side limit of bearer bar 3 hinged, bearer bar 3 is hinged with base top, and jacking cylinder 5 piston rod drives bearer bar 3 to overturn, thus realizes 45-60 ° of upset of screen frame.
