Embodiments of the present invention will be further described with reference to the accompanying drawings. Fig. 1 is a schematic structural diagram of an embodiment of a concrete mixing plant dust-settling device, and as shown in the figure, the concrete mixing plant dust-settling device comprises a mixing bin 1 and feed inlets 4 arranged on two sides of the mixing bin 1, discharge pipes 12 are arranged on two sides of the bottom end of the mixing bin 1, the feed inlets 4 are communicated with a feeding mechanism, the feeding mechanism comprises a storage bin 2 and a conveyor belt 3, one end of the conveyor belt 3 is communicated with the storage bin 2, and the other end of the conveyor belt 3 is arranged in the mixing bin 1 after penetrating through the feed inlets 4. Because the feed inlet 4 of stirring storehouse 1 sets up in its upper portion, the grit that transports through conveyer belt 3 drops to the lower part from upper portion, must produce great impact force, and the vibration produces a large amount of dusts, and the dust is derived and the polluted environment from feed inlet 4, is provided with two feed inlets 4, and the feeding handling capacity is big.

Be provided with puddler 8 and two in the stirring storehouse 1 and accept board 5, it sets up in the below of feed inlet 4 to accept board 5, the one end of accepting board 5 is rotated with the inner wall of stirring storehouse 1 and is connected, the other end of accepting board 5 contacts with another other end of accepting board 5, it is provided with buffer gear between the lower surface of accepting board 5 and the inner wall of stirring storehouse 1, buffer gear includes telescopic link 6 and spring 7, the one end of telescopic link 6 is rotated with the inner wall of stirring storehouse 1 and is connected, the other end of telescopic link 6 is rotated with the lower surface of accepting board 5 and is connected, the one end of spring 7 and the inner wall fixed connection of stirring storehouse 1, the other end of spring 7 and the lower fixed surface of accepting board 5 are connected. Accept board 5 and set up in the below of feed inlet 4 mainly used and accept the feeding at higher height, the grit descends highly lower, the vibration of production is less, and then the dust is less, the lower surface of simultaneously accepting board 5 is provided with telescopic link 6 and spring 7, an impact force for buffering grit decline production, almost not produce the dust, when the grit is in two and accept continuous piling up on board 5, when weight is great, telescopic link 6 shortens, the spring 7 compression, two accept board 5 and rotate to the direction of discharging pipe 12, form the logical material clearance between it, the grit falls to stirring storehouse 1 lower part through the logical material clearance.

Spray the mechanism and set up in the top of stirring storehouse 1 and aim at the upper surface of accepting board 5, spray the mechanism and include a plurality of shower nozzles 13 and the delivery pipe that is linked together with shower nozzle 13, the delivery pipe is linked together with the storage water tank, shower nozzle 13 quantity reduces along the one end of accepting board 5 to its other end gradually, shower nozzle 13 mainly aims at the other end of conveyer belt 3, carry out preliminary humidification before the grit descends to accepting on board 5, avoid producing the dust, because the grit is piled up from the one end of accepting board 5 to the other end gradually, consequently two positions of accepting between the board 5 need not to set up more shower nozzle 13, cause the waste. The top of puddler 8 sets up in the below of accepting board 5, the bottom of puddler 8 is worn out and is connected with agitator motor 9 behind the bottom of stirring storehouse 1, puddler 8 from the top down has set gradually supporting mechanism and stirring rod 11, supporting mechanism includes a plurality of arcs 10 that from the top down set gradually, the top of puddler 8 is located to the middle part cover of arc 10, arc 10 bends to the direction of puddler 8 bottom, the diameter of a plurality of arcs 10 increases gradually to the direction of its bottom along the top of puddler 8. Because the logical material clearance is that the grit weight is piled up the back and is opened, consequently, it is little to lead to the material clearance, the grit that drops in following the logical material clearance mostly drops to on the arc 10 of puddler 8 topmost, arc 10 rotates along with the rotation of puddler 8, the grit above that the arc 10 of top gets rid of the arc 10 of next layer through centrifugal force, the arcwall face of arc 10 can reduce the grit and fall the vibration that produces on its surface, until the grit drops to 1 bottom of stirring storehouse and stirs with stirring rod 11, this in-process is accepted board 5 and grit and can be separated between feed inlet 4 and the 8 tops of puddler, even the puddler 8 stirs or the grit descends the in-process step by step between arc 10 and produces the dust, can not all produce the pollution through feed inlet 4 entering atmospheric environment.

The specific implementation process of the utility model is as follows: store the grit in the storehouse 2 and transport the upper portion to stirring storehouse 1 through conveyer belt 3, shower nozzle 13 tentatively humidifies the grit, reduce the production of dust, then the grit drops to accepting on board 5 from conveyer belt 3, accept the grit on board 5 and pile up to certain weight after, accept the other end downward sloping of board 5, two accept and produce the logical material clearance between the board 5, the grit falls to a plurality of arcwall 10 that set up from top to bottom in proper order through leading to the material clearance, drop to stirring storehouse 1 bottom until the grit, stirring rod 11 stirs the grit, after the stirring is accomplished, derive through discharging pipe 12.

Therefore, according to the concrete mixing station dust falling device adopting the structure, the receiving plate and the receiving mechanism are adopted to continuously reduce the impact force of the sand and stone falling to the bottom end of the mixing bin, reduce vibration and further avoid dust generation.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: modifications and equivalents may be made to the utility model without departing from the spirit and scope of the utility model.
