Embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises sampler 1, double stroke cylinder 2, air-operated solenoid valve 3, cycle time relay 4, sampler inner core 5, material inlet 6, material outlet 7 and hose connector 8, source of the gas signal input port 9, the inside of sampler 1 is provided with sampler inner core 5, described sampler inner core 5 connects the hose connector 8 of sampler 1 outside, and the outlet of hose connector 8 connects material outlet 7; The outside of described sampler 1 is provided with double stroke cylinder 2, described double stroke cylinder 2 is provided with source of the gas signal input port 9, air-operated solenoid valve 3 is connected to by source of the gas signal input port 9, cycle time relay 4 exports electric signal and enters air-operated solenoid valve 3, the source of the gas signal of described air-operated solenoid valve 3 enters double stroke cylinder 2 through source of the gas signal input port 9, described sampler inner core 5 is to action in feed bin, material enters sampler inner core 5 from material inlet 6, sampler inner core 5 is to action outside feed bin, and material enters material outlet 7 by hose connector 8.
Wherein, sampler inner core 5 comprises inner core 5.1, charging aperture 5.2, discharging opening 5.3, pull bar 5.4, plug 5.5, O-ring seal 5.6, the front end of inner core 5.1 is provided with charging aperture 5.2, the lower end of inner core 5.1 is provided with discharging opening 5.3, the inside of inner core 5.1 is provided with plug 5.5, the rear end cylinder lever connecting rod 5.4 of described plug 5.5, described pull bar 5.4 connects double stroke cylinder 2, described pull bar 5.4 is provided with plug 5.6 with the junction of inner core 5.1, discharging opening 5.3 connects hose connector 8, realize quantitative timing sampling, improve the accuracy of sampling efficiency and sampling result.
Principle of work: double stroke cylinder utilizes the source of the gas signalizing activity of solenoid valve, material extracts the material in silo by sampler inner core, and each sampling amount of sampler inner core is set to 0.03kg; In order to ensure the quality of sample, the period of circulation relay can be regulated, increasing the sampling number of times in the unit interval.Sampling number of times in unit hour is kept to be less than 5 times, in order to be the sealing of protection cylinder etc., the serviceable life of extension device.
