There are one positive and negative rotation driving motors 12 for fixed setting on the bottom end right angle outer side surface of the right angle pipeline of pipeline 4, described positive and negative
Turn on the output end of driving motor 12 by shaft coupling be connected with 10 state in a vertical shape of rotary screw sealing be inserted into air lead
In the tube chamber in flow tube road 4, also there are one L-shaped current limlitings to keep off for adaptation setting in the inner cavity of the right angle pipeline of the air conducting pipeline 4
Plate 9 is integrally fixed with guide nut 11, institute at the horizontal component plate body right end position of the L-shaped flow restriction baffle 9 in perforation form
The body of rod for stating rotary screw 10 is mutually adapted across the setting of guide nut 11, the right side of the right angle pipeline of the air conducting pipeline 4
Also state in a vertical shape setting is there are one directive slide track 7 on the internal face of side, on the right side of the vertical portion ontology of the L-shaped flow restriction baffle 9
Two groups of leading blocks 8 are additionally provided on wall, two groups of leading blocks 8 are adapted in the track groove of directive slide track 7, logical in this way
It crosses and the air conducting pipeline 4 of traditional single structure is improved, in actual work, by vehicle under the action of air inducing fan 6
Between in dust laden air be pumped into air conducting pipeline 4, enter in air purification cabinet 3 later, air is led in this process
It is slower to enter rate, and after opening positive and negative rotation driving motor 12, you can it drives the body of rod of entire rotary screw 10 to carry out positive direction and turns
Dynamic, since rotary screw 10 and guide nut 11 are equipped with, guide nut 11 can be under the rotational action of rotary screw 10
Entire L-shaped flow restriction baffle 9 is driven slowly to move up, and since the special construction of L-shaped flow restriction baffle 9 is arranged, and then can
The tube body size that air conducting pipeline 4 is in end-position is directly reduced, certain baffle effect is played, i.e., leads at this time
The air entered is imported into rapidly by larger space in smaller space, is similar to the operation principle of " Venturi tube " so that air gas
Body rate when entering air purification cabinet 3 can be got higher, and " be poured " in air purification cabinet 3 with higher rate, and positive and negative
When turning the reversion of driving motor 12, L-shaped flow restriction baffle 9 can slowly decline so that air gas is when entering air purification cabinet 3
Rate can reduce, and be entered in air purification cabinet 3 with lower rate, and then effectively realize the speed of air gas importing
Adjust purpose, solve rate that the air conducting pipeline 4 of traditional single structure occurs when entering air draught it is too slow or
Too fast problem, it is more adaptable, subsequently to be provided the foundation with best effect dust separation.
The cabinets cavity bottom of the air purification cabinet 3 is provided with lifting jolting plate 13, the lifting jolting plate 13
It is connected with the bottom end of the double-deck dust removal filter cloth 16 by lower fixed seat 15 at plate body upper surface middle part position, the bilayer dust removal filter cloth
16 top is arranged by upper fixed seat 14 at the inner cavity top wall surface medium position of air purification cabinet 3, the air purification
State also in a vertical shape is provided with two groups of telescopic supporting rods 17, the telescopic supporting rod 17 at the cabinets cavity bottom position of cabinet 3
Body of rod top be fixed on the lower face of lifting jolting plate 13, the body of rod bottom end of the telescopic supporting rod 17 is fixedly installed
