Described frame side is provided with the conveying device corresponding to described feed hopper, and described conveying device includes by the conveyer belt of the second driven by motor and the hopper being arranged at described conveyer belt bottom, and described conveyer belt is inclined and mounted on to be had on the dolly of roller; Described microprocessor has wireless transmitter module, and described second motor is connected by the wireless receiving module that is connected with the second driver element and described wireless transmitter module;
Its control method is: flow sensor responds to feed rate in real time, and pass to microprocessor after the flow signal detected in real time is converted to the signal of telecommunication, microprocessor carries out contrasting according to predetermined range of flow and the flow signal value responded in real time, after analyzing and processing, this flow signal is passed to the aperture of the real-time Controlling solenoid valve of the first driver element; Meanwhile, this flow signal is transferred to wireless receiving module by wireless transmitter module by microprocessor, and this flow signal is passed to the rotating speed that the second driver element controls the second motor in real time by wireless receiving module.
In technique scheme, technical scheme can also be more specifically: the output shaft of described motor is set with moving runner, described moving runner has radially-protruding projection, be hinged with connecting rod between this projection and described vibrating head, described vibrating head passes every layer of described screen cloth successively and is fixedly connected with described screen cloth.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, owing to have employed flow sensor and by this flow signal of microprocessor analysis process, the aperture of real-time Controlling solenoid valve and the transporting velocity of conveying device, automatically tea leaf conveying can be regulated to send the amount of hopper to and enter the amount of screening room according to tealeaves flowing velocity, avoid too much causing hopper not contain into tealeaves and overflowing, and the offending problem of sieving and grading;
2, owing to being divided into screening room and selection by winnowing room by dividing plate in casing, bulky tealeaves is corresponding to be deposited on every layer of screen cloth, and the tea quality difference of residual sand grains and small size is more suitable for greatly selection by winnowing, selection by winnowing cleaner and thoroughly;
3, due to feed hopper being provided with motor, motor is by vibrating head, and describedly screen indoor at least two-layer screen cloth and be fixedly connected with being contained in, its vibrating head directly acts on screen cloth, vibrating effect significantly, economize energy and structure is simple;
4, because frame side is provided with mobilizable conveying device, the used time can not removed, and does not only easy to usely also take up space.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
This tea dry sorting control method, use the tea grading machine shown in a kind of Fig. 1, this tea grading machine, the casing 1 comprising frame 9 and be arranged in frame 9, screening room 1b and selection by winnowing room 1a is divided into by dividing plate 14 in casing 1, correspond on the casing 1 above screening room 1b and be provided with feed hopper 4 and motor 3, two-layer screen cloth 2 is provided with in screening room 1b, as shown in Figure 2, the output shaft of motor is set with moving runner 3, moving runner 3 has radially-protruding protruding 31, connecting rod 32 is hinged with between this protruding 31 and vibrating head 33, vibrating head 33 is successively through every layer of screen cloth 2, seal 34 is provided with between vibrating head 33 and every layer of screen cloth 2, vibrating head 33 is fixedly connected with each layer screen cloth 2 respectively by the seal 34 of each layer, the aperture of screen cloth 2 reduces from top to bottom successively, corresponding to casing 1 sidewall above every layer of screen cloth being provided with screening discharging opening 12, the frame 9 of casing 1 side is provided with hair-dryer 7, the tuyere 71 of hair-dryer 7 to be located in the 1a of selection by winnowing room by the pipeline being installed on casing 1 sidewall and to be positioned at below undermost screen cloth 2, is being disposed with 3 selection by winnowing discharging openings 11 away from casing 1 sidewall of tuyere 71, feed hopper 4 is provided with flow sensor 10, feed hopper 4 exit is provided with magnetic valve 13, as shown in Figure 3, the signal output part of flow sensor 10 is connected with the signal input part of microprocessor 15, and the signal output part of microprocessor 15 is connected with the automatically controlled end of magnetic valve 13 by the first driver element 18,
Frame 9 side is provided with the conveying device corresponding to feed hopper 4, and conveying device includes conveyer belt 5 and is arranged at the hopper 6 of conveyer belt 5 bottom, and conveyer belt 5 is inclined and mounted on to be had on the dolly 8 of roller 81; Microprocessor 15 has wireless transmitter module, and the second motor 14 is connected with wireless transmitter module by the wireless receiving module 16 be connected with the second driver element 17;
Its control method is: flow sensor 10 responds to feed rate in real time, and pass to microprocessor 15 after the flow signal detected in real time is converted to the signal of telecommunication, microprocessor 15 carries out contrasting according to predetermined range of flow and flow signal value respond in real time, after analyzing and processing, this flow signal is passed to the aperture of the real-time Controlling solenoid valve 13 of the first driver element 18; Meanwhile, this flow signal is transferred to wireless receiving module 16 by wireless transmitter module by microprocessor 15, and this flow signal is passed to the rotating speed that the second driver element 17 controls the second motor in real time by wireless receiving module 16.
