At first, because the fuselage two ends are connected to form the annular enclosed type structure with head and support respectively, inside is carried out transmission by the transportation rubber belt that the varying number hopper is installed with the great wheel connection of being connected with tail wheel.And layers of material or long-term sideslip wearing and tearing can appear in transportation rubber belt in real work, and unexpected phenomenon of rupture occurs, if in time do not find, can cause the feeding discharge end to stop up, the cleaning difficulty, and maintenance is inconvenient, and the flow process paralysis can't move before and after making.
Secondly, make the slipping of the belt phenomenon because the surface coating wearing and tearing can appear in for a long time use of belt pulley, if initiatively and driven pulley all skid, can cause the belt pulley transportation rubber belt improving material of can't working that dallies.
In addition, if charging control is bad, sends into the support material and too much can cause putty, hopper can't be worked, or gig degree of utilization out of reach optimum regime, affect the process of whole production of fodder, reduced the production efficiency of feed factory.
Yet at present gig charging and mode of operation all can not get Real Time Monitoring, and the feed rate of some apparatus for feeding is not easy control, keep in repair thereby can not in time go and find out what's going on when causing gig that various fault occurs, and cause more large economy loss to the user.
Summary of the invention
The purpose of this utility model provides the control setup of a kind of Real Time Monitoring gig electric current and rotating speed, running state that can the Real Time Monitoring gig, prevent that gig is when improving material, transship, the problem such as stall, make equipment be operated in normal condition or optimum regime, and ensure continuously reliably operation of manufacturing line, and guaranteed constant product quality, improved the production efficiency of feed factory.
The technical solution of the utility model: the control setup of a kind of Real Time Monitoring gig electric current of the present utility model and rotating speed comprises current testing device, speed measuring device, Programmable Logic Controller PLC, industrial computer, protection and warning device, its current testing device comprises the main motor current supply circuit current transformer that is installed in the gig head, the mouth of transformer is connected to the amperemeter/ammtr input end, the analog signal of amperemeter/ammtr output is connected impulse singla and is connected with Programmable Logic Controller PLC with speed measuring device, Programmable Logic Controller PLC is connected with industrial computer; The mouth of Programmable Logic Controller PLC is connected with halt switch with the gig startup, and the mouth of Programmable Logic Controller PLC also is connected with protection and warning device.
Described speed measuring device comprises the bending plate that tests the speed that is bolted on the gig driven shaft; At the gig bearing seat adapter plate that tests the speed is installed, inductance approach switch is fixed on the adapter plate that tests the speed corresponding with the bending plate that tests the speed.
Advantage of the present utility model: the utility model provides the control setup of a kind of simple and effective Real Time Monitoring gig electric current and rotating speed, can gather in real time, calculate to monitor electric current and the rotating speed of gig, and automatically control gig front end feed process equipment start-stop, guarantee that gig work is in optimum regime, according to image data judgment device fault cause, effectively troubleshooting avoids causing more serious economic loss.
