It is operated first personnel Turbogrid plates 3 are put into ditch, and then Turbogrid plates 3 is stuck in ditch by fixed link 9, carry out
When draining, Turbogrid plates 3 block the sundries in water.After 3 prolonged use of Turbogrid plates, operator can step on motion plate 5
It moves down, transverse slat 5, which moves down, drives strut 4 to move down, and the compression of the first spring 6, it is living that strut 4 moves down drive first
Movable plate 10 moves down, and the first movable plate 10, which moves down, drives the first push plate 11 to move down, and second spring 8 stretches, and first
Push plate 11, which moves down, strikes off the sundries remained in 3 hole of Turbogrid plates, and sundries strikes off rear washed away.When the first push plate
11 when being moved downward to bottom, can unclamp transverse slat 5, because of the effect of the first spring 6, strut 4 move up band motion plate 5 to
Upper movement restores to original position, while the first movable plate 10 also being driven to move up, and the first movable plate 10 moves up drive first
Push plate 11 moves up recovery to original position, because of the effect of second spring 8, can make that the first push plate 11 resets faster, more preferably.
When operator, which steps on motion plate 5, to be moved down, the first movable plate 10 is moved down while being driven in through-hole 134
Component moves down, and when fixture block 133 is moved downward to bottom, fixture block 133 is contacted with kelly 138, because of the 4th spring 1311
Effect, left and right sides fixture block 133 block kelly 138, and when operator unclamps transverse slat 5, the first movable plate 10 is moved up
It drives the first push plate 11 to move up to restore to original position, meanwhile, the first movable plate 10 drives kelly 138 upward by fixture block 133
Mobile, kelly 138, which moves up, drives the second movable plate 137 to move up, and the second movable plate 137 moves up drive second and pushes away
Plate 139 moves up, and third spring 136 stretches, and the second push plate 139, which moves up, carries out the impurity being sticked in 3 hole of Turbogrid plates
It strikes off.When fixture block 133 is moved upward to the top, fixture block 133 is contacted with contact block 131, and contact block 131 pushes the left and right sides
Fixture block 133 is displaced outwardly, and left and right sides fixture block 133 is displaced outwardly to be detached from kelly 138, because of the effect of third spring 136, third
Guide sleeve 135, which moves down, drives the second movable plate 137 to move down, and the second movable plate 137, which moves down, drives the second push plate 139
It moves down and restores to original position, while kelly 138 being driven to move down recovery to original position.In this way, impurity can be prevented to be sticked to grid
The left and right sides influences draining in 3 hole of plate.
When operator, which steps on motion plate 5, to be moved down, the first push plate 11 moves down while driving guide rod 15 to moving down
Dynamic, guide rod 15, which moves down, drives scraper plate 17 to move down, and scraper plate 17 moves down further to left and right two in 3 hole of Turbogrid plates
The impurity of side is struck off, and because of the effect of the 5th spring 16, scraper plate 17 is contacted in 3 hole of Turbogrid plates always.In this way, can be to grid
Impurity in 3 hole of plate strikes off more clean.
When initial, the 6th spring 20 of left side is tensional state, and the 6th spring 20 of right side is compressive state, when the second push plate
139 when moving up, and the second push plate 139 drives inserted link 24 to move up simultaneously, and inserted link 24 is moved up to be taken off in wedge groove 22
From because of the effect of the 6th spring 20, movable plate 21, which is moved to the left, loosens the soil of bottom in ditch.When the second push plate 139
When moving down, the second push plate 139, which moves down, drives inserted link 24 to move down, and inserted link 24 moves down to be driven in insertion card slot
Movable plate 21 moves right, and movable plate 21 moves right recovery to original position, and the 6th spring 20 of left side stretches and the 6th spring of right side
20 compressions.In this way, can prevent the soil in ditch from living Turbogrid plates 3 is caused to be difficult to take out by 1 knot of N-shaped seat.
