Description

Technical Field

[0001] The utility model belongs to the technical field of dust suppression equipment, and specifically relates to a dust suppression device. Background Art

[0002] Sand and gravel aggregate is a general term for sand, pebbles (gravel), crushed stone, blocks, and materials such as stone in water conservancy projects. It is the main building material for structures such as concrete and stacked stones in water conservancy projects. Due to the large amount of dust generated during the mining and transportation of sand and gravel aggregates, the dust will fly everywhere, which will not only pollute the environment, but also be detrimental to the health of production personnel. Therefore, dust reduction equipment is needed at the sand and gravel aggregate mining and transportation sites.

[0003] At present, the existing dust suppression equipment usually adopts a spraying method, using a spray plate to spray water mist at a high altitude to achieve the effect of dust suppression. However, in traditional dust suppression equipment, the spray plate is generally fixedly installed, and the water mist spraying range of a single spray plate is limited. If comprehensive dust suppression is required at the sand and gravel aggregate mining and transportation site, more spray plates need to be installed, which increases the dust suppression cost. For this reason, the present application proposes a dust suppression device. Utility Model Content

[0011] Preferably, the slide rail and the push-pull arm are perpendicular to each other, and the rotation radius of the second guide column is half the length of the slide rail.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] This embodiment provides a dust suppression device, and its structural schematic diagram is as follows: Figure 1-Figure 5 As shown, it includes a support arm 1; a mounting plate 2 fixed at the top of the support arm 1, and connecting strips 3 are fixed at both ends of the mounting plate 2; a spray plate 4 rotatably mounted between a pair of connecting strips 3; a driving mechanism 5 arranged on the mounting plate 2 for driving the spray plate 4 to swing back and forth, the spray plate 4 is supported and mounted on one side of a sand and gravel aggregate conveying line or a mining site through the support arm 1, and the spray plate 4 is connected to a high-pressure water source and can be used for spraying dust suppression, wherein, by utilizing the rotatable installation of the spray plate 4 and utilizing the driving mechanism 5 to drive the spray plate 4 to swing back and forth, with a limited number of spray plates 4, dust suppression can be carried out on sand and gravel aggregate conveying and mining sites in a larger range, thereby reducing the cost of dust suppression and having a high practical value.

[0025] As a preferred technical solution in this embodiment, the driving mechanism 5 includes: a mounting seat 6 fixed at the middle position of the mounting plate 2, a driven arm 8 fixed at the middle position of the spray plate 4, a push-pull arm 7 horizontally slidably penetrated through the mounting seat 6, and a power component arranged on the mounting seat 6 for driving the push-pull arm 7 to reciprocate, the push-pull arm 7 is slidingly connected and cooperated with the driven arm 8, wherein the power component includes a slide rail 11 arranged at one end of the push-pull arm 7 away from the driven arm 8, a rotating arm 13 rotatably mounted on the mounting seat 6, and a driving motor 12 installed on the mounting seat 6 for driving the rotating arm 13 to rotate, the end of the rotating arm 13 is rotatably connected with a second guide column 14, and the second guide column 14 is slidably cooperated with the slide rail 11. Through this structural mode, the driving motor 12 is started to drive the rotating arm 13 to rotate, driving the second guide column 14 to slide back and forth along the slide rail 11, thereby forcing the push-pull arm 7 to move back and forth. The push-pull arm 7 is slidably connected with the driven arm 8, and the reciprocating movement of the push-pull arm 7 will drive the driven arm 8 to swing back and forth. Then the connecting strip 3 will swing back and forth driven by the driven arm 8, which is used for large-scale dust suppression.

[0026] In this embodiment, the slide rail 11 and the push-pull arm 7 are perpendicular to each other, and the rotation radius of the second guide column 14 is half the length of the slide rail 11 .

[0027] In this embodiment, a guide groove 9 is provided on the driven arm 8, and a first guide column 10 is rotatably connected to one end of the push-pull arm 7 toward the driven arm 8. The first guide column 10 is slidably engaged with the guide groove 9 to realize the sliding connection and cooperation between the push-pull arm 7 and the driven arm 8. During the reciprocating movement of the push-pull arm 7, the first guide column 10 is driven to slide along the guide groove 9, forcing the driven arm 8 to drive the connecting strip 3 to swing back and forth.

[0028] Furthermore, in the present embodiment, an adjusting arm 15 is movably provided on one end of the push-pull arm 7 toward the driven arm 8, the first guide column 10 is assembled on the end of the adjusting arm 15, and a first positioning bolt 16 which can be tightly pressed against the adjusting arm 15 is threadedly provided on the side wall of the push-pull arm 7. By extending and retracting the adjusting arm 15 at the end of the push-pull arm 7 and tightening and positioning it with the first positioning bolt 16, the initial swing angle of the connecting strip 3 can be adjusted.

[0029] Furthermore, in the present embodiment, the support arm 1 includes a fixed arm 17 and a movable arm 18 movably inserted at the top of the fixed arm 17, a second positioning bolt 19 is threadedly inserted on the side wall at the top of the fixed arm 17, and a plurality of positioning screw holes 20 which can be threadedly plugged into and adapted to the second positioning bolt 19 are opened on the side wall of the movable arm 18. By telescopically adjusting the movable arm 18 at the top of the fixed arm 17 and using the second positioning bolt 19 to threadably plug and position the positioning screw hole 20, the initial height of the connecting strip 3 can be adjusted.

[0030] Working principle: When in use, the support arm 1 is installed on one side of the sand and gravel aggregate conveying line or the mining site, and then the spray plate 4 is connected to the high-pressure water source, which can be used for spraying dust suppression to prevent the dust generated during the sand and gravel aggregate conveying or mining process from floating around and polluting the environment. Furthermore, by starting the drive motor 12 to drive the rotating arm 13 to rotate, the second guide column 14 is driven to slide back and forth along the slide rail 11, thereby forcing the push-pull arm 7 to reciprocate and translate. By using the sliding cooperation between the first guide column 10 and the guide groove 9 on the driven arm 8, the reciprocating movement of the push-pull arm 7 will drive the driven arm 8 to swing back and forth, and the push-pull arm 7 will move back and forth. That is, the connecting strip 3 swings back and forth driven by the driven arm 8, so that with a limited number of spray plates 4, dust suppression can be carried out on the sand and gravel aggregate transportation and mining sites over a larger range, thereby reducing the dust suppression cost. Furthermore, the initial swing angle of the connecting strip 3 can be adjusted by extending and retracting the adjusting arm 15 at the end of the push-pull arm 7 and tightening and positioning it with the first positioning bolt 16. The initial height of the connecting strip 3 can be adjusted by extending and retracting the movable arm 18 at the top of the fixed arm 17 and using the second positioning bolt 19 and the positioning screw hole 20 for threaded insertion and positioning, which has high flexibility.
