Picture 2-3: Working Principle 3
1. High-pressure blower
2. Control box
3. Buzzer
4. Material inlet pipe
5. Storage hopper
6. Materials
7. Discharging plate
8. Photoelectric switch
When the machine is on, the high pressure blower(1) starts to work, and it
makes storage hopper(5) generate the vacuum. The discharging plate(7) is
closed, and then materials in silo get into the storage hopper(5) through material
inlet pipe(4) owing to air pressure. When the loader finishes its work, high
pressure blower(1) stops working, and materials(6) will drop off because of
gravity. When the photoelectric switch(8) detects there
’
s no material, high
pressure blower(1) will start to work again. When the loader can
’
t suck the
material or there is material shortage, buzzer(3) on the control box(2) will sound
an alarm.
