Abstract
The utility model discloses an automatic retractable dust cover for quarries, which comprises a dust cover housing (4), the lower end of the dust cover housing (4) is connected with a retractable sleeve (6), and a flared cover (9) is mounted on the lower end of the retractable sleeve (6). The automatic retractable dust cover can be widely used at positions with severe dust pollution, such as discharge outlets of conveyer belts, discharge outlets of equipment and loading positions, stone can be slowly discharged out under a hermetical state, the flared discharge outlet can automatically rise as the stone beneath is increased, and thereby fall dust which is produced in the process of discharging and loading can be effectively controlled.
Description
Technical field
The utility model relates to a kind of dust cover of quarrying machinery.
Background technology
According to statistics, quarry dust mainly pulverizes and sieves the production processes such as discharging and transportation from feeding intake, and the industrial dust majority producing in exploitation of stone process is the free silicon dioxide that contains a great deal of.Live in for a long time resident and workman that high concentrate dust environment contains above free free silicon dioxide, again without suitable dustproof facilities, in several years, likely cause and take silicon proteinosis as main acute silicosis disease, pneumoconiosis very easily occurs.
Present stone factory's dust prevention is mainly adopt watering operation and enter to purchase cleaner, but position, stone pit is often very remote, is neighbouringly difficult to find enough water sources, does not possess the condition of the operation of sprinkling water.And for a lot of small-sized stones field, entering to purchase specially cleaner can increase cost undoubtedly greatly, therefore in China most areas, more than 90 percent stone pit does not possess qualified dustproof condition.
Summary of the invention
The technical problems to be solved in the utility model: for the excessive problem of present quarry dust, provide a kind of stone factory automatic expanding dust cover.
Technical solutions of the utility model:
Stone factory's 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.
Dust cover housing inner side 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 of dust cover housing are installed and are adjusted screw rod, adjust the installation slip of screw rod upper end and buckle.
Twist device is installed on dust cover housing, by twisted wire, connects horn cover.
Twisted wire is elastic shrinkage line.
The utility model beneficial effect:
1. stone factory's 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, can under sealing state, slowly building stones be discharged, discharging horn mouth can along with the increase of below building stones, automatic-ascending can effectively be controlled at the drop dust producing 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, guarantee that dust can not overflow from dust cover.
3. adopt twist device and resilient strand to disperse the gravity of horn cover, can below pressure also can automatic-ascending very little in the situation that, improve sensitivity.
accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is the side view of figure mono-.
the specific embodiment:
As figure, roller 2 is installed on support 1, roller 2 drives conveyer belt 3 motions, dust cover housing 4 is arranged on conveyer belt 3 ends, by adjusting screw rod 9 and slip, buckle 4 and be fixed on support 1, sliding buckles 4 position and can adjust by adjusting screw rod 9, and being screwed slides buckles 4 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 be from overflowing above.Dust cover housing 4 lower ends connect telescopic 6, and horn cover 9 is installed in telescopic 6 lower ends.Twist device 12 is installed on dust cover housing 4, by twisted wire 11, connects horn covers 9, twisted wire 11 has elasticity, weight that can balance horn cover 9.
