Abstract

The utility model relates to a single driving multiroll screening machine used for screening sintered pellets or distributing materials in metallurgy industry. A machine frame is provided with driving units which are composed of motors and bearing seats, and screen rolls. A set of driving unit is only connected with a screen roll. The shaft end of each screen roll is arranged in the bearing seat and connected with a speed reducing motor by a load limiting shaft connector. Thus, the utility model can avoid screws being breaking off in the flange connection. When sundries clamp the screen rolls, the load limiting shaft connector can play the action of protecting the motors and protecting the screen rolls from being broken and bent. The utility model has the advantages of simple and compact structure, convenient maintenance and replacement and favorable rigidity. Besides, the utility model reduces the failure rate, extends the service life of the complete machine, saves the work load of daily maintenance, reduces maintenance costs and improves productivity.

Description

The moving multiple roll screening machine of patrilineal line of descent with only one son in each generation

Technical field

The utility model belongs to screening of metallurgy industry agglomerates of sintered pellets or cloth technical field, relates to the moving multiple roll screening machine of a kind of patrilineal line of descent with only one son in each generation.

Background technology

The screening machine that existing metallurgy industry agglomerates of sintered pellets screening or cloth are used is prone to the phenomenon of the stuck sieve roller of foreign material because motor does not have overload protection in the production process, even motor takes place is burnt, the sieve roller fault such as curved of spraining; Because the sieve roller generally adopts ring flange to connect with bearing block, its connection screw is easy to sprain disconnected, and screening machine is damaged, and safeguards more change poles inconvenience.

Summary of the invention

The purpose of this utility model is to solve above-mentioned prior art problem and a kind of reduction fault rate is provided, and increases the service life, and safeguards and changes the moving multiple roll screening machine of patrilineal line of descent with only one son in each generation easily.

The technical solution adopted in the utility model: a kind of patrilineal line of descent with only one son in each generation moves the multiple roll screening machine, its frame is provided with the gear unit and the sieve roller of motor, bearing block formation, one group of gear unit only connects a sieve roller, and the axle head of sieve roller is installed in the bearing block, and connects with reducing motor by the limit for tonnage shaft coupling.

On the described bearing block striker plate is installed.

The small end of the sieve roller catcher of described limit for tonnage shaft coupling is provided with sieve roll shaft hole, big end is provided with groove, be provided with the motor catcher in the groove, groove inwall five equilibrium has arc groove, the small end of motor catcher is provided with motor axis hole, holds greatly radially that five equilibrium has slotted hole, is provided with the pin rod that spring and upper end are circular arc in each slotted hole, the pin rod is provided with spacer pin, and spacer pin is installed in the pin-and-hole of motor catcher.

Described gear unit is at least six groups, is staggered spread pattern and connects firmly on frame.

The positive beneficial effect that the utility model produces:

1. will sieve roll shaft and be directly installed on the bearing block, ring flange has been omitted in the centre, avoids flange to connect screw and sprains disconnected;

2. adopt the limit for tonnage shaft coupling to connect with reducing motor, when foreign material blocked the sieve roller, the limit for tonnage shaft coupling had played the effect of protection motor, and protection sieve roller is not sprained curved simultaneously;

3. it is moving to adopt one group of gear unit only to drive the patrilineal line of descent with only one son in each generation of a sieve roller, make simple and compact for structure, safeguard change convenient;

4. good rigidly, fault rate reduces, and has prolonged the service life of complete machine, saved the maintenance work amount, reduced maintenance cost, boosted productivity, about 60 tons of general small-sized pellet production line hourly output, large-scale about 300 tons, make steady production secure so reduce equipment failure rate.

The specific embodiment

Consult Fig. 1, shown in Figure 2, a kind of patrilineal line of descent with only one son in each generation moves the multiple roll screening machine, adopts one group of gear unit only to drive the patrilineal line of descent with only one son in each generation flowing mode of a sieve roller, and every group of gear unit mainly comprises reducing motor 1, frame 2, limit for tonnage shaft coupling 3, bearing block 4, striker plate 5, sieve roller 6 etc.; Be fixedly connected with reducing motor 1, bearing block 4 on its frame 2, the axle head of sieve roller 6 is directly installed in the bearing block 4, and connects with reducing motor 1 by limit for tonnage shaft coupling 3, and striker plate 5 is installed on the bearing block 4.

Consult Fig. 3, shown in Figure 4, described limit for tonnage shaft coupling 3 comprises sieve roller catcher 301, pin rod 302, spacer pin 303, spring 304 and motor catcher 305; The small end of its sieve roller catcher 301 is provided with sieve roll shaft hole, big end is provided with groove, groove inwall five equilibrium has six to 16 arc grooves, be provided with motor catcher 305 in the groove, the small end of motor catcher 305 is provided with motor axis hole, holding radially greatly, five equilibrium has three to eight slotted holes, be provided with the pin rod 302 that spring 304 and upper end are circular arc in each slotted hole, the arc end of pin rod 302 is stuck in the arc groove of sieve roller catcher 301 during normal operation, pin rod 302 1 sides are provided with the elongated stopper slot, spacer pin 303 is installed in the stopper slot, and spacer pin 303 is installed in the pin-and-hole of motor catcher 305.

Gear unit of the present utility model is many groups, be at least six groups, many group gear units are staggered spread pattern and connect firmly on frame 2, owing to adopt every group of gear unit only to drive the patrilineal line of descent with only one son in each generation flowing mode of a sieve roller 6, can drive a plurality of sieve rollers 6 respectively so organize gear unit more.

Operation principle of the present utility model: when reducing motor 1 is subjected to moment of torsion near overload values; spring 304 is compressed; selling excellent 302 arc grooves that skid off sieve roller catcher 301 this moment begins to skid; and send the slip sound of rattling away; reducing motor 1 dallies and sieves roller 6 and do not change at this moment, has so just realized overload protection.
