CN201313736Y - Fixing device of feed plate or sieve plate of vibrating machine - Google Patents

Abstract

The utility model relates to a fixing device of the feed plate or sieve plate of a vibrating machine, which comprises a feed plate or sieve plate, a small beam, a clamping bolt, a press plate, a sleeve, a disc spring and a nut. The long circular head of the clamping bolt penetrates through the split-type press plate so as to clamp and press the feed plate or the sieve plate; after the clamping bolt is arranged to penetrate through the small beam, the sleeve is arranged at the lower end of the small beam; and the feed plate or the sieve plate is fixedly linked with the small beam through the disc spring and the nut. The utility model has the advantages of optimized structure, low manufacturing cost and convenient maintenance and replacement, and solves the problems that the maintenance can not be promptly performed and the normal operation of the vibrating machine is affected due to the loosening of the feed plate or sieve plate.

Description

The anchor fitting of shakeout machine dish plate or sieve plate

Technical field

The utility model relates to the anchor fitting of a kind of shakeout machine dish plate or sieve plate.

Background technology

Shakeout machine is to utilize vibrotechnique to make load-carrying element produce directional vibration, finishes conveying, feed or the screening operation of material.Be applicable to industries such as metallurgy, coal, chemical industry and building materials, be realize to loose in shape or the lump material, one of the ideal style of short range conveying, feed and screening.Because the feed box and the screen box of shakeout machine are worked under high temperature and the synergy of high-frequency vibration power for a long time, feed frame, screen frame easily produce stress concentration and cause endurance failure, require dish plate with the feed frame, sieve plate should be fastening with proof strength with connecting of screen frame, the while is convenient to replacing again.Dish plate commonly used, sieve plate with the mode that is adopted that connects of needle beam is: at feed frame or screen frame middle part and adopt tapered bar between adjacent two, the mode that is connected and fixed of pad and middle pressing plate, middle pressing plate is pushed down middle dish plate or sieve plate both sides simultaneously, the tapered bar nut, belleville spring is fixed on the saddle type pressing plate of feed box or screen box, compress tapered bar with turning nut, inclined-plane by tapered bar compresses the pad that passes again, this fixed mechanism complex structure, and the tapered bar level is installed in the square hole of needle beam, be not easy to change, maintenance, the vertical direction thrust that adopts this structural adjustment to produce simultaneously, dish plate or sieve plate are very easily loosening under the effect of periodic vibration power, and it is bad to compress effect.

The utility model content

The technical matters that the utility model need solve is: the complex structure that exists at existing shakeout machine anchor fitting, easily become flexible, be not easy to the problem of changing and keeping in repair, and a kind of device of fastening better effects if is provided.

Technical solution adopted in the utility model: the anchor fitting of this shakeout machine dish plate or sieve plate comprises feed or sieve plate, needle beam, push bolt, pressing plate, sleeve pipe, disk spring, nut.Long Circle head on the push bolt blocks feed or sieve plate and push down by the dissection type pressing plate, pass needle beam after, load onto sleeve pipe in the needle beam lower end, and dish plate or sieve plate firmly be connected on the needle beam with disk spring and nut.

The beneficial effects of the utility model: the utlity model has structure optimization, low cost of manufacture, the advantage of convenient maintenance and replacement has solved because of the loosening problem that can not on-call maintenance perplexs the shakeout machine normal operation of dish plate or sieve plate.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is the E-E part sectional view of Fig. 1;

Fig. 3 is the D-D part sectional view of Fig. 2;

Fig. 4 is the F-F part sectional view of Fig. 2.

Among the figure: 1. feed box or screen box, 2. dish plate or sieve plate, 3. push bolt, 4. pressing plate, 5. needle beam, 6. sleeve pipe, 7. belleville spring, 8. nut.

The specific embodiment

Referring to Fig. 1-Fig. 4, the utility model comprises feed or sieve plate 2, needle beam 5, push bolt 3, pressing plate 4, sleeve pipe 6, disk spring 7, nut 8.Long Circle head on the push bolt 3 blocks feed or sieve plate 2 and push down by dissection type pressing plate 4, pass needle beam 5 after, load onto sleeve pipe 6 in needle beam 5 lower ends, and feed or sieve plate 2 firmly be connected on the needle beam 5 with disk spring 7 and nut 8.The utility model push bolt 3 compresses pressing plate 4 by disk spring 7, nut 8 owing to adopting the step axis hole to cooperate to block with pressing plate 4 again, actv. has prevented that dish plate or sieve plate 2 are under the effect of periodical high-frequency vibratory force, cause the play of horizontal direction, locking, compress effective; Adopt the strong disk spring 7 of buffering vibration absorption ability, to fastener Yin Gaowen produce stress relaxation and cause looseningly carry out the thermal elongation compensation, adopt push bolt 3 pass needle beam 5 install nuts 8 and dissection type pressing plate 4 structures make mechanism dismounting, change convenient.Solved because of the loosening problem that can not on-call maintenance perplexs the shakeout machine normal operation of dish plate or sieve plate.

Claims (1)

1, the anchor fitting of a kind of shakeout machine dish plate or sieve plate, comprise dish plate or sieve plate (2), needle beam (5), push bolt (3), pressing plate (4), sleeve pipe (6), disk spring (7), nut (8), it is characterized in that: the Long Circle head on the push bolt (3) is by dissection type pressing plate (4), dish plate or sieve plate (2) are blocked and push down, after passing needle beam (5), load onto sleeve pipe (6) in needle beam (5) lower end, and dish plate or sieve plate (2) firmly are connected on the needle beam (5) with disk spring (7) and nut (8).
