The technical proposal is as follows: the axes of the three excitation motors are arranged in parallel, tension springs are arranged at the same radial positions of the upper parts (or the lower parts) of the eccentric blocks on one side of the two excitation motors rotating in the same direction, the same tension springs are arranged at the same radial positions of the lower parts (or the upper parts) of the eccentric blocks on the other side of the two excitation motors rotating in the same direction, and the approximately zero-phase synchronization is realized under the synchronous state of the two excitation motors rotating in the same direction through the tension changes of tension forces of the tension springs on the two sides. The other exciting motor and the two exciting motors rotating in the same direction rotate in the same speed and opposite directions, so that elliptical motion of the screen box is realized.

Description
Technical Field
The invention relates to a double-tension spring coupled elliptical vibrating screen with three excitation motors, in particular to a large screening area heavy screen which is widely applied to industries such as petroleum drilling, metallurgy, food, mine and the like and needs large excitation force.
Background
Currently, vibrating screens are gradually developed towards large-scale, high-strength, large-throughput and the like. However, due to the limitation of the site, many researchers have proposed double-layer sieves and multi-layer sieves, thereby increasing the sieving area. With the adoption of double-layer and multi-layer screens, the total vibration-taking mass of the system is increased, and further, higher requirements are put on the excitation force of the system. In order to overcome the defect of insufficient vibration force of a double-layer screen or multi-layer screen double-vibration motor, the multi-vibration motor is driven to operate. The ZL 201410160965.7 proposes a self-synchronous translational elliptical vibrating screen with three excitation motors, and the self-synchronous system of the three excitation motors drives the self-synchronous system relative to the double excitation motors, and the sum of the excitation forces of the three excitation motors is increased, but due to the electromechanical coupling effect of the system, the two excitation motors rotating in the same direction can generate opposite phase synchronization, and most of the excitation forces of the two excitation motors cancel each other, so that the system cannot fully exert the excitation forces of the three excitation motors. Aiming at the problems, the Chinese patent ZL 201510227417.6 proposes that a coupling unit is arranged at one side of two excitation motors rotating in the same direction, so that synchronization near zero phase is realized. The influence of the coupling unit on the synchronous state of the system is found to be larger in the experimental stage of the prototype, and the clamping phenomenon of the system is easily caused by processing and installation errors of the coupling unit and the like. CN 201610728411.1 proposes a torsional spring coupled elliptical vibrating screen with three excitation motors, which solves the problem of coupling two excitation motors installed coaxially, but still cannot solve the problem existing between two co-rotating excitation motors with parallel but different axes. In order to solve the problems, the elliptical vibrating screen with the three excitation motors based on double tension spring coupling is provided.
Disclosure of Invention
Aiming at the defects of the three-excitation motor elliptical vibrating screen in coupling, the invention provides the double-tension spring coupling three-excitation motor elliptical vibrating screen which is simple in structure and convenient to install.
The invention adopts the following technical scheme.
A double-tension spring coupled elliptical vibrating screen with three excitation motors mainly comprises a screen box, a first excitation motor, a second excitation motor, a third excitation motor, tension springs, supporting springs, a base, eccentric blocks of the second excitation motor, eccentric blocks of the third excitation motor, spring fixing blocks, pin sleeves, pins, a first fixing plate, a round rod, a second fixing plate, locking nuts, a screw rod, hooks, a motor base and the like. The screen box is supported on the base through a spring, the exciting motor is fixed on a screen box side plate through a motor base, the second exciting motor and the third exciting motor are installed in parallel, and the same eccentric mass moment is adopted to run at the same speed and in the same direction. The first excitation motor is installed in parallel with the axes of the second excitation motor and the third excitation motor, and the steering direction of the first excitation motor is opposite to the steering direction of the second excitation motor and the third excitation motor, and the rotating speeds are the same. The tension springs are arranged at the same radial positions of the upper parts (or the lower parts) of the eccentric blocks on one side of the second vibration motor and the third vibration motor which rotate in the same direction, and the same tension springs are arranged at the same radial positions of the lower parts (or the upper parts) of the second vibration motor and the eccentric blocks on the other side, which are opposite to the eccentric blocks of the third vibration motor.
The connecting part of the tension spring and the eccentric block of the exciting motor mainly comprises a spring fixing block, a pin sleeve, a pin, a first fixing plate, a round rod, a second fixing plate, a locking nut, a screw rod, a hook and the like. The pin bush is arranged on the spring fixing block, and the pin bush of the spring fixing block is connected with the eccentric block through a pin and can do rotary motion around the pin. And a hook which can rotate relatively is arranged on one side of the spring fixing block at the connecting part of the tension spring and the eccentric block end of the exciting motor, and the tension spring is connected. And a screw rod is welded at the connecting part of the tension spring and the other end of the eccentric block of the exciting motor, one side of the spring fixing block is welded with a screw rod, two smooth round rods are parallelly arranged in the spring fixing block, the two round rods can do relative sliding motion relative to the spring fixing block, and two ends of the round rods are welded with fixing plates which are parallel to each other. One of the fixing plates is connected with the tension spring, the other fixing plate is arranged on a spring fixing block with a screw rod, and the tension springs on two sides can keep certain pretightening force by adjusting the locking nuts on the screw rod in front of and behind the fixing plate. .
Before starting, the eccentric blocks are all at the lowest position under the action of gravity, at the moment, the spring at one side is at the lowest position, and the tension spring at the other side is at the highest position. When the exciting motors are started, because of the difference of the specificity of the exciting motors, the eccentric blocks of the two exciting motors rotating in the same direction cannot be synchronously started at the same speed, so that the two exciting motors have a phase difference, the tension force of the tension spring on one side is increased, the tension force of the tension spring on the other side is reduced, and the magnitude of the tension force difference of the two springs is in direct proportion to the phase difference of the two exciting motors. In the synchronization process, the tension of the tension springs at the two sides is alternately changed, so that the stress states of the tension springs at the two sides are consistent, and the phases of the two eccentric blocks are synchronous at 0 degrees. When the system is in a steady state, the second exciting motor and the third exciting motor are synchronized by stabilizing the phase difference of the second exciting motor and the third exciting motor to be near 0 degrees through tension springs at two sides. In addition, after the three excitation motors synchronously run at the same speed, the power supply of one of the two excitation motors rotating in the same direction can be turned off, the other excitation motor is only electrified, the vibrating screen can still continuously work to realize elliptical motion, and the vibration parameters are basically the same as those of the original system.
The invention has the advantages that: (1) The tension spring realizes the near zero phase synchronization of the two excitation motors rotating in the same direction in the steady state, and overcomes the defect of the elliptical vibrating screen with three excitation motors in coupling. (2) The vibrating screen is suitable for a multi-layer screen driven by a multi-excitation motor with large treatment capacity and large screening area, and has good market application prospect. (3) The vibrating screen has the advantages of simple structure, easy installation, easy maintenance, low cost and the like.
