Abstract
The invention discloses a kind of automatic expanding dust cover, comprise dust cover housing (4), dust cover housing (4) lower end connects telescopic (6), horn cover (7) is installed in telescopic (6) lower end, be provided with impeller (14) in dust cover housing (4), rotating shaft (12) two ends of impeller (14) connect horn cover (7) by twisted wire (11).The present invention can be widely used in the dust pollutions such as conveyer belt discharging mouth, equipment discharging opening, entrucking and seriously locate, slowly building stones can be discharged in sealed states, discharging horn mouth can rise automatically along with the increase of below building stones, effectively can control the drop dust produced in discharging and entrucking process.
Description
Technical field
The present invention relates to a kind of dust cover of quarrying machinery.
Background technology
According to statistics, quarry dust mainly pulverizes and sieves the production process such as discharging and transport from feeding intake, the industrial dust produced in exploitation of stone process majority is the free silicon dioxide containing a great deal of.Live in resident and workman that high concentrate dust environment contains above free free silicon dioxide for a long time, again without suitable dustproof facilities, namely likely cause based on the acute silicosis of silicon proteinosis sick in several years, very easily pneumoconiosis occurs.
Present stone factory's dust prevention mainly adopts watering operation and enters to purchase cleaner, but position, stone pit is often very remote, and neighbouring being difficult to finds enough water sources, does not possess the condition of watering operation.And for a lot of small-sized stone field, entering to purchase cleaner specially can increase cost undoubtedly greatly, therefore in China's most area, the stone pit of more than 90 percent does not possess qualified dust-proof condition.
Summary of the invention
The technical problem to be solved in the present invention: for the problem that present quarry dust is excessive, provide a kind of automatic expanding dust cover.
Technical solution of the present invention:
A kind of automatic expanding dust cover, comprises dust cover housing, and dust cover housing lower end connects telescopic, and horn cover is installed in telescopic lower end, and horn cover cross section is up-small and down-big shape.
Be provided with impeller in dust cover housing, the rotating shaft two ends of impeller connect horn cover by twisted wire.
Dust cover case inside is provided with sealing flexible glue circle.
The conveyer belt arrival end of dust cover housing is provided with baffle plate, and the conveyer belt port of export is provided with scraper plate.
The both sides mounting and adjusting screw rod of dust cover housing. adjustment screw rod upper end is installed slip and is buckled.
Twisted wire end is provided with extension spring.
Rotating shaft is that two ends respectively have a cam, and the protrusion direction of two cams is contrary, and twisted wire is wrapped on cam.
Horn cover is provided with balancing weight.
Beneficial effect of the present invention:
1. automatic expanding dust cover can be widely used in the dust pollutions such as conveyer belt discharging mouth, equipment discharging opening, entrucking and seriously locates, slowly building stones can be discharged in sealed states, discharging horn mouth can rise automatically along with the increase of below building stones, effectively can control the drop dust produced in discharging and entrucking process.
2. dust cover and roller of conveyer belt are combined closely, and by side seal flexible glue circle, upper and lower baffle plate and scraper plate, ensure that dust can not overflow from dust cover.
3. the gravity adopting sandstone to fall promotes horn cover, also can automatically can rise when below pressure is very little, improves sensitivity.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the side view of Fig. 1.
detailed description of the invention:
As figure, support 1 is provided with roller 2, roller 2 drives conveyer belt 3 to move, dust cover housing 4 is arranged on conveyer belt 3 end, buckled 8 be fixed on support 1 by adjustment screw rod 9 and slip, the position buckling 8 of sliding can be adjusted by adjustment screw rod 9, is screwed slip and buckles 8 and support 1.There is the form fit of arc groove and roller 2 dust cover housing 4 both sides, and sealing flexible glue circle 5 is installed in the inner side of arc groove, sealing flexible glue circle 5 and conveyer belt 3 form sealing, the conveyer belt arrival end of dust cover housing 4 is provided with baffle plate 13, the conveyer belt port of export is provided with scraper plate 10, so just makes the dust in dust cover housing 4 can not overflow from above.Dust cover housing 4 lower end connects telescopic 6, and horn cover 7 is installed in telescopic 6 lower end.Be provided with impeller 14 in dust cover housing 4, the width-adjustable of impeller 14 blade is whole, and rotating shaft 12 two ends of impeller 14 connect horn cover 7 by twisted wire 11, and twisted wire 11 end is provided with extension spring.Respectively there is a cam at rotating shaft 12 two ends, and the protrusion direction of two cams is contrary, and twisted wire 11 is wrapped on cam.Horn cover 7 is provided with balancing weight 15.
The principle of moving on horn cover 7 is automatic is, when in horn cover 7, spoil pile can be spread out to surrounding, due to horn cover 7 gradient, horn cover 7 one component upwards can be given when building stones are spread out, balance its gravity, give again impeller 14 with pressure when building stones fall simultaneously, when the torque that the gravity of horn cover 7 gives impeller 14 be less than building stones fall to giving the torque of impeller 14 time, impeller 14 will rotate, twisted wire 11 is shortened, and horn cover 7 rises, simultaneously due to the effect of cam, can shake left and right when horn cover 7 rises, the constraint of building stones can be departed from fast.
