Description
Technical field
The utility model relates to the conveying that is used for material and a kind of sieve nest of sorting, and more particularly it is a kind of two-way connecting rod vibratory sieve, and it is applicable to industries such as mine, metallurgy, building materials.
Background technology
At present, the feed vibratory sieve of domestic utilization, decades and do not change, there is data to show or " American technology " quoted, it is the transmission of a kind of employing driven by motor belt pulley, run up thereby drive the main shaft that eccentric weight is housed, and make sieve nest vibrate (as Fig. 1) by effect of inertia.There is following shortcoming in the vibratory sieve that adopts this mode to vibrate: 1, dangerous: the vibratory sieve that has through investigation is in operation, and finds that eccentric weight flies out or the main shaft spindle nose disconnects, thus the security incident of causing.2, change trouble after this vibratory sieve rotating speed height (per minute 900 turn left the right side), so bearing easily generates heat, weares and teares, and material is not easy to screen clean.3, because this equipment is that the alignment of shafts directly connects sieve nest, the sieve nest biside plate is shaken split easily, be difficult for repairing, and the bad adjustment of forward and backward amplitude.When 4, rotating speed was high, noise was big, and power consumption is big simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the weak point of above-mentioned existing vibratory sieve, and a kind of two-way connecting rod vibratory sieve is provided, and it has changed the shortcoming of above-mentioned sieve nest, has security of operation, energy savings, advantage of simple structure.
The purpose of this utility model reaches by following measure: two-way connecting rod vibratory sieve, and it comprises motor 3, base 1, spring support 2, sieve nest 11, vibrating spring 12, the two ends of spring support 2 connect base 1 and sieve nest 11 respectively; One end of vibrating spring 12 is fixed on the spring support 2, and the other end is fixed on the major axis 10; It is characterized in that it also comprises excentric sleeve 5, dynamic link 6, joint bearing block 8, tiltedly draws connecting rod 9, support 13, described excentric sleeve 5 is connected with motor 3 by belt 14, the two ends of dynamic link 6 connect joint bearing block 12 and excentric sleeve 5 respectively, described joint bearing block 8 is fixed on the support 13, the described end of connecting rod 9 that tiltedly draws is connected with support 13, and the other end is fixed on the spring support 2.
In technique scheme, described dynamic link 6 is connected with joint bearing block 12 by minor axis 7.
In technique scheme, the described connecting rod 9 that tiltedly draws is connected with joint bearing block 12 by minor axis 7, and described minor axis 7 is positioned at the center of gravity of sieve nest 11.
In technique scheme, between described excentric sleeve 5 and the base 1 fixed bearing block 4 is arranged, described excentric sleeve 5 is fixed on the fixed bearing block 4.
The two-way connecting rod vibratory sieve of the utility model has following advantage: 1, do not have unsafe factor, some parts gone wrong, security incident can not occur, and simultaneously easy to maintenance.2, conservation of power, as produce 400 tons of building stones original equipment motor 7.5-11KW daily, now as long as 4KW produces 800 tons of building stones original equipment motor 11-15KW daily, the existing 5.5KW that only needs.Through measuring and calculating, the two-way connecting rod vibratory sieve that the user uses needs only 3-4, and the electricity charge of saving just can be bought a new machine, and cost is low.3, change vibrative mode: adopt excentric sleeve to drive dynamic link, make its upper and lower motion drive sieve nest and produce vibration.4, utilize mechanics principle, other installs one and tiltedly draws connecting rod to hold the sieve nest center of gravity, reduces the upper and lower resistance of motion of dynamic link, and utilizes it to regulate whole sieve nest moving equilibrium.5, between dynamic link and sieve nest, design and installation a support, the vibration force of having disperseed sieve nest can not be shaken the sieve nest biside plate and split, and props up the effect of erecting instrumentality material import and export amplitude simultaneously, and is convenient to change bearing, and is easy to maintenance.6, sieve nest per minute rotating speed is designed to 600 right sides of turning left, and former sieve per minute rotating speed is 900 right sides of turning left, so bearing temperature is low, and noise is little, and material sieves well.
Description of drawings
Fig. 1 is the structural representation sketch of existing vibratory sieve;
Fig. 2 is the structural representation of the two-way connecting rod vibratory sieve of the utility model.
The specific embodiment
Describe the performance that has vibratory sieve and the two-way connecting rod vibratory sieve of the utility model now in detail below in conjunction with accompanying drawing, advantage of the present utility model like this will become clear and understand easily.
Fig. 1 is that base, 2 is that spring support, 3 is that motor, 4 is that fixed bearing block, 5 is that excentric sleeve, 6 is that dynamic link, 7 is that minor axis, 8 is that joint bearing block, 9 is that major axis, 11 is that sieve nest, 12 is that vibrating spring, 13 is that support, 14 is that belt, 15 is an eccentric weight for tiltedly drawing connecting rod, 10.
Consult Fig. 1 as can be known: existing vibratory sieve is to adopt motor to drive eccentric weight 15 by belt, thereby the generation vibration at high speed, this eccentric weight 15 complex manufacturing technology, difficulty of processing is big, eccentric weight 15 is easy to fly out or the disconnection of main shaft spindle nose simultaneously, causes security incident.Eccentric weight 15 biside plates shake easily and split in addition, are difficult for repairing, thereby cause sieve nest to scrap, and simultaneously this sieve nest maintenance is trouble very.The reason that produces above-mentioned shortcoming mainly is because unreasonable the causing of vibrational structure of sieve nest.
