2604 and third through-hole 2602, strike bar 2603 and contacted with the left lower of screening frame 3, when allowing middle husky and fine sand faster by second
After filter screen 9 is fallen on the first filter screen 8, worker by pulling pull bar 2605 to be stretched to left movement, second spring 2604, and then
Pull bar 2605, which drives, strikes bar 2603 to left movement, reaches and strikes after bar 2603 leaves the purpose contacted with the left lower of screening frame 3,
Releasing lever 2605, pull bar 2605 and strikes bar 2603 and is moved right in the effect of the elastic force of second spring 2604 and return to original position, so
Repeatedly, 2603 continuous side-to-side movement of bar is struck, it becomes possible to realize to the bottom of screening frame 3 and the purpose of the first filter screen 8, so, just
Fine sand can be allowed to be sorted faster by the first filter screen 8, further reach shortening screening time, improve work effect
Rate.
Because it is stainless steel that the material of frame 1, which is stainless steel material, stainless steel corrosion resistance and acid resistance are strong, make equipment
Service life is longer.
Because the material of screening frame 3 is Q235 steel, Q235 steel hardness is high and does not allow yielding, makes the service life of equipment more
It is long.
