Background technology
At present the rice of China's machining high-precision grade mainly comprises following flow process: paddy, just clear, cleaning, de-stone, rice huller paddy, the rough separation of paddy, husked rice selection (thickness classification), multistage light stone roller, rice grading, multistage polishing, rice grading, from meter Jing Xuan (length grading), look choosing purify, packing, warehouse-in.
Rice, in the course of processing, need to repeatedly be promoted to eminence by cereal from lower, and its lifting means adopts gig mostly.On market, cereal adopts belt transmission substantially with gig, this belt transmission is to be fixedly connected with a plurality of winnowing pans at belt lateral surface, belt pulley rotates, drive belt movement, thereby drive winnowing pan motion, the winnowing pan of belt one side moves from bottom to top, and cereal is promoted to eminence from lower, and cereal is drawn off from discharge port.
The lifting process of existing gig is generally more steady, but also have the following disadvantages: (1) adopts belt conveyor reinforced because existing gig is reinforced, and the reinforced flow of belt conveyor does not have control setup, there is sometimes reinforced interrupted or reinforced too many situation, will cause like this material putty in gig, (2) the reinforced belt due to cereal may become flexible, easily skid, skid when serious, belt pulley idle running, cereal no longer promotes, and a large amount of cereal is deposited in gig bottom, and putty phenomenon occurs.Occur, after putty phenomenon, can make gig quit work, cause the interruption of production process, affect production efficiency.
Utility model content
The purpose of this utility model be exactly in order to overcome the defect that above-mentioned prior art exists, provide a kind of simple in structure, be easy to the volume control device for rice lifting machine controlling, enhance productivity.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of volume control device for rice lifting machine, be located on rice lifting machine and rice load-transfer device, described rice lifting machine comprises cylindrical shell, be located at the inlet point of cylinder body bottom, be located at the discharging opening at cylindrical shell top, be located at the roller at the upper and lower two ends of inner barrel, the electrical motor that driving rolls rotates, be wrapped in belt and the equidistant a plurality of winnowing pans that are fixedly connected on belt in roller outside, described rice load-transfer device is obliquely installed, the top of rice load-transfer device is provided with rice feed bin, the bottom of rice load-transfer device is connected in inlet point, this control setup comprises flow control valve, weight sensor and controller, described flow control valve is arranged on the upper end of rice load-transfer device, described weight sensor is located in inlet point, described controller is fixed on cylindrical shell, controller is connected with electric wire respectively with flow control valve and weight sensor.
Described controller is PLC controller.
Described flow control valve is pneumatic gate valve, and this pneumatic gate valve is connected with cylinder, controlled by cylinder, and described controller is connected with cylinder is electronic, the opening time of control cylinder, and then the action of control pneumatic gate valve.
Between two rollers, be provided with the adjusting screw mandrel that regulates two roller relative positions.By regulating screw mandrel can regulate the degree of tension of belt.
While using device of the present utility model, by weight sensor, respond to the weight of the rice in inlet point, and then judgement inlet point in rice number, then signal is passed to controller, controller is again to flow control valve transmitted signal, by controlling the size of flow control valve and then the flow that control flows to the rice of inlet point, when in weight sensor senses inlet point, material is more, controller is controlled the flow that flow control valve reduces rice, when in weight sensor senses inlet point, material is less, controller is controlled the flow that flow control valve increases rice.
Compared with prior art, the utlity model has following advantage:
(1) simple in structure, be easy to realize, only need on gig and rice load-transfer device, flow control valve, weight sensor and controller be installed, and flow control valve, weight sensor and controller are to overhaul and change device easily;
(2) device of the present utility model is easy to control, and control accuracy is higher, the number of rice in inlet point by weight sensor, can accurately be detected, and by the control of controller and flow control valve, avoided the putty phenomenon of rice in gig, reduce gig because of the out-of-work fault of putty, improved capacity utilization rate, improved production efficiency.
