A support frame 6 is arranged on one side of the electro-hydraulic push rod 5, the electro-hydraulic push rod 5 is fixedly connected with the support frame 6 through a mounting seat, and the lower limit approaching switch 7, the initial limit approaching switch 8 and the upper limit approaching switch 9 are respectively and fixedly connected with the support frame 6 through corresponding switch seats. The support frame 6 can be erected on an operation platform 10 below the material separating device.
The inner surface of the three-way chute 1 is provided with a wear-resistant material layer, and the material-separating turning plate 2 is made of a wear-resistant metal material.
The length of the crank 4 is at least 3 times of the height of the material-separating turning plate 2.
A can realize feed divider of equalling unloading lastingly work method as follows:
(1) when the material distributing device starts to work, the electro-hydraulic push rod 5 is started to reach an initial working position II; because the length of the crank 4 is multiple times of the height of the material-dividing turning plate 2, and the included angle between the electro-hydraulic push rod 5 and the crank 4 is kept at 90 degrees at the initial working position II, the force couple formed by the impact of the incoming material flow on the material-dividing turning plate 2 is smaller than the reverse force couple formed by the self-locking force of the electro-hydraulic push rod 5, the rigid connecting structure cannot rotate around the shaft 3, and the material-dividing turning plate 2 is always kept in a vertical state (corresponding to the initial position I), so that the uniform equal-dividing blanking of the three-way material distributor to 2 discharge;
(2) the electro-hydraulic push rod 5 stops after reaching the initial working position II, and the self-locking force of the electro-hydraulic push rod gradually decreases along with the lapse of time; after the self-locking force is reduced to a critical value, a reverse force couple formed by the self-locking force of the electro-hydraulic push rod 5 is smaller than a force couple formed by impacting the material flow on the material distribution turning plate 2, and at the moment, the material distribution turning plate 2 drives the rigid connecting structure to rotate around the central line of the shaft 3; when the material-separating turning plate 2 rotates clockwise or anticlockwise by an angle alpha, the connecting end of the crank 4 and the electro-hydraulic push rod 5 enters the sensing range of the upper limit approaching switch 9/the lower limit approaching switch 7, the corresponding approaching switch 9/7 immediately sends a signal to the control system, the control system receives the signal and then sends an instruction to the electro-hydraulic push rod 5, and the electro-hydraulic push rod 5 drives the crank 4 to move, so that the material-separating turning plate 2 returns to the initial position; after the material-separating turning plate 2 returns to the initial position, the connecting end of the crank 4 and the electro-hydraulic push rod 5 enters the induction range of the initial position close to the switch 8, and the electro-hydraulic push rod 5 stops running through the control system; therefore, the material distributing turning plate 2 is always in a set range in the material distributing process, and the three-way material distributor is finally used for evenly and equally distributing the materials to the 2 material outlets.
As shown in fig. 4, it is a force couple balance analysis diagram of the material separating device capable of realizing equally divided blanking in the invention during operation; the couple that supplied material stream impact divides the branch material to turn over board 2 formation is FR, the reverse couple that electro-hydraulic drive push rod 5 formed under the self-locking effect among the feed divider is FR. Because the linear distance R of the material-separating turning plate deviating from the initial position is far less than the length R of the crank, the force couple FR formed by the impact of the incoming material flow on the material-separating turning plate is less than the reverse force couple FR formed by the electro-hydraulic push rod 5 under the action of self-locking force, so that the whole rigid connecting structure cannot rotate around the central line of the shaft 3, and the top end of the material-separating turning plate 2 is always kept near the initial position I.
After the electro-hydraulic push rod 5 reaches the initial working position II and stops, the self-locking force of the electro-hydraulic push rod gradually decreases along with the time. After the auto-lock power drops to certain numerical value, the reverse force couple that electro-hydraulic push rod 5 formed under the auto-lock power effect is less than the supplied material stream and strikes the couple that divides the material and turn over board 2 formation, makes the branch material turn over board 2 tops and begin to drift to the outside from initial position I, at this moment, through turn over board positioner control branch material and turn over the board automatic initial condition that returns. The working principle is as follows: as shown in fig. 2, when the material-separating turning plate 2 rotates by an angle α counterclockwise (in the direction shown in the figure) from the initial position i, the crank 4 also rotates by an angle α counterclockwise. When the connecting end of the crank 4 and the electro-hydraulic push rod 5 enters the induction range of the upper limit approaching switch 9, the upper limit approaching switch 9 immediately sends a signal to a control system (PLC), the control system receives the signal and then sends an instruction to the electro-hydraulic push rod 5, and the crank 4 is driven and the material-dividing turning plate 2 is driven to rotate clockwise. When the top end of the material-separating turning plate 2 returns to the initial position I, the connecting end part of the crank 4 and the electro-hydraulic push rod 5 enters the induction range of the initial position proximity switch 8, the initial position proximity switch 8 immediately sends a signal to the control system, and the control system receives the signal and then sends an instruction of stopping operation to the electro-hydraulic push rod 5. On the contrary, as shown in fig. 3, when the material-separating turning plate 2 rotates clockwise by an angle α from the initial position i, the crank 4 also rotates clockwise by an angle α. The connecting end of the crank 4 and the electro-hydraulic push rod 5 enters the induction range of the lower limit approaching switch 7, the lower limit approaching switch 7 immediately sends a signal to the control system, and the control system receives the signal and then sends an instruction to the electro-hydraulic push rod 5 to drive the crank 4 and drive the material-dividing turning plate 2 to rotate anticlockwise. When the top end of the material-separating turning plate 2 returns to the initial position I, the connecting end of the crank 4 and the electro-hydraulic push rod 5 enters the induction range of the initial position proximity switch 8, the initial position proximity switch 8 immediately sends a signal to the control system, and the control system receives the signal and then sends an instruction of stopping operation to the electro-hydraulic push rod 5. Through the control of the turning plate positioning device, the material-distributing turning plate 2 can only rotate in a very small interval near the initial position I, the range of the interval is set manually according to needs, the material-distributing process of the material-distributing device after setting does not need manual intervention, and finally, ideal and lasting equally-distributing blanking effect can be achieved.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
