In order to prevent the barrel turning arm from axially sliding on the transverse shaft, the barrel turning arm is fixed by a set screw. The barrel overturning arm can be manually rotated by about 95 degrees according to the rotating direction shown in figure 8; when the induction iron rotates, the induction iron welded at the lower part of the barrel overturning arm rotates together with the barrel overturning arm; when the induction iron leaves the induction head of the proximity switch of the counter, the proximity switch of the counter provides an electric signal to the time frequency recorder to record the sample extraction time (Beijing time) and the accumulated frequency at the time.
The working principle of the present invention is explained below.
1) Supplying power to the electric cabinet and then closing the air switch; 2) starting the air compressor until the set pressure is reached and automatically stopping the air compressor; 3) rotating a three-position change-over switch on the door of the electric control box to 'automatic', and enabling the PLC to be electrified and enter an automatic state to be started; 4) the PLC program is started, firstly, the cylinder does reciprocating motion to enable the material taking frame 23 to take cement clinker out of the aggregate chute 20 at the lower part of the crusher; then the cement clinker enters a receiving hopper 4 of the elevator through a collecting hopper 24 and a material sliding pipe 29; the operation of the hoister is also controlled by a program of the PLC, and the hoister starts to operate under the driving of the speed reducing motor 1211 after the receiving hopper 4 obtains the materials for four seconds; a head proximity switch 33 is installed at a proper position on the top of the elevator, when the receiving hopper 4 runs to a position just needing to discharge the sample materials, the receiving hopper 4 is just inducted with the proximity switch to enable the head proximity switch 33 to provide an electric signal to the PLC, and the PLC can immediately instruct a control element to power off and stop the speed reducing motor 1211 after receiving the signal and enable the receiving hopper 4 to just stop at the position shown in figure 2; after stopping for four seconds, the receiving hopper 4 automatically and accurately returns to the initial position again. Similarly, a tail proximity switch 1224 is mounted in place on the lower portion of the elevator (flush with the bottom of the hopper); the receiving hopper is arranged at the head of the lifter and used for accurately returning to a receiving position at the tail of the lifter after sample materials in the hopper are discharged; when the bottom edge of the receiving hopper passes through the tail proximity switch at an instant, the proximity switch generates an induced electrical signal due to the principle of electromagnetic induction and provides the induced electrical signal to the PLC, and the PLC immediately cuts off the power of the running speed reduction motor and stops the speed reduction motor after receiving the electrical signal, so that the receiving hopper can be accurately stopped at a set position.
The above is a complete automatic sampling of the invention, if a temporary manual sampling is needed, the whole process under the above sampling state can be completed only by rotating the three-position change-over switch to manual. The storage capacity of the storage bucket 51 is about 20L, when a user carries out manual sample lifting, the user needs to rotate the bucket turning arm anticlockwise for about 95 degrees, at the moment, the counter proximity switch 58 installed at a proper position can sense the induction iron at the lower end of the bucket turning arm 55 to provide an electric signal for the time frequency recorder, at the moment, the time frequency recorder records the sample lifting time and the sample lifting frequency, and the recorder is used for avoiding cheating.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims.
