Embodiment
The utility model is further described below by embodiment
(1) shaft sampling apparatus
Shaft sampling apparatus is the first step realized to the measurement sampling of silo inside grain.In the utility model, shaft is adopted
Sampling device is formed by the thief hatch among tube bottom stepper motor and tube body, strainer and into grain passage etc..
Stepper motor is a device for electric pulse being converted into discrete mechanical movement, has good data control spy
Property, and it can open ring position control, input one pulse signal just obtain a defined positional increment, such so-called increasing
Position control system is measured compared with traditional DC control system, its cost substantially lowers, and must hardly carry out system call interception.Cause
The power set rotated in this utility model using stepper motor as tube wall, allow outer tube wall to accomplish that open loop rotates control
System.
Shaft sampling arrangement samples process is as follows：
Tube bottom stepper motor drives outer tube wall to rotate by gear and slideway, since the strainer on outer tube wall is with stretching out sampling
Mouthful be in same level position into grain passage, therefore when strainer skims over thief hatch part by rotation, the grain of grain heap can be
Strainer is pressed under the action of pressure, is entered via into grain passage among sampling room.To avoid disposably entering excessive grain
Sample, can be adjusted by the selection to strainer and the number for changing the tube bottom stepper motor speed rotated and skimming over.
Shaft stepper motor, thief hatch and screen location are as shown in Figure 1.
(2) sampling and measuring device
Sampling and measuring device is made of sampling room 7, tube top stepper motor 6 and the indoor multiple sensors of sampling, responsible pair
