In order to prevent the asphalt raw materials and cold materials from being mixed and melted unevenly in the mixing drum and affecting the viscosity of the asphalt, the cold materials are generally heated in the heating drum, and then the cold materials are mixed with the hot materials. In the process of adding cold materials, the cold materials are generally put into the cold material bin first, one kind of cold material is put in one cold material bin, and then multiple cold material bins are arranged side by side. A conical bucket is provided on the lower side of each cold material bin to facilitate the discharge of the cold material in the cold material bin, and a feeder is provided on the lower side of the conical bucket for the discharge of the cold material from the cold material bin. Multiple cold material bins are arranged in a straight line, and a conveyor belt is provided on the lower side of the cold material bin so that the cold material discharged from the cold material bin can fall on the conveyor belt and be transported to the heating drum via the conveyor belt.

[0003] Among them, when the cold material in the cold material bin falls on the conveyor belt, due to the height difference, serious dust will be generated on the conveyor belt. The existing technology prevents excessive dust dispersion by covering the cold material bin.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] See also Figure 1-5 , the embodiment of the present invention provides the following two technical solutions:

[0031] Embodiment 1: An asphalt concrete cold material feeding equipment comprises a plurality of cold material conveyor belts 1, and a main conveyor belt 2 arranged below the plurality of cold material conveyor belts 1, a plurality of support frames 3 are erected above the main conveyor belt 2, a dust removal cylinder 4 used in conjunction with the cold material conveyor belt 1 is fixedly installed on the top of the support frame 3, and in order to avoid large-scale dust of the cold material entering the dust removal cylinder 4, a dust cover 403 used in conjunction with the cold material conveyor belt 1 is fixedly installed on the top of the dust removal cylinder 4.

[0032] As a preferred solution, in order to reduce the dust of cold materials falling on the total conveyor belt 2, a plurality of buffer dust collecting parts 5 are alternately arranged on both sides of the inner cavity of the dust collecting cylinder 4 from top to bottom, and the buffer dust collecting parts 5 include a buffer box 501, and a dust filter 502 is fixedly embedded on the inclined surface of the buffer box 501. One side of the buffer box 501 is in sliding contact with one side of the inner cavity of the dust collecting cylinder 4, and a slide plate 503 is fixedly installed on one side of the buffer box 501. First slide grooves 401 are opened on both sides of the dust collecting cylinder 4, and the slide plate 503 is slidably installed in the first slide groove 401. Inside, a balancing block 504 is fixedly installed on one side of the slide plate 503, one side of the balancing block 504 is in sliding contact with some of the dust collector 4, and two sliding rods 505 are penetrated and slidably installed on the top of the balancing block 504, and a lap plate 506 is fixedly installed on the bottom ends of the two sliding rods 505. A spring 507 is sleeved on the outer periphery of the sliding rod 505, and the two ends of the spring 507 are respectively in contact with the opposite side of the balancing block 504 and the lap plate 506, and several lap plates 506 are respectively fixedly installed on both sides of the dust collector 4.

[0033] In this embodiment, not only can the descending speed of the cold material be reduced, but also the dust in the cold material can be screened and collected, effectively reducing the dust generated when the cold material falls on the main conveyor belt 2.

[0034] Embodiment 2

[0035] This embodiment is an improvement of the previous embodiment. An asphalt concrete cold material feeding device also includes a wind dust suction component 6 arranged in the support frame 3. The wind dust suction component 6 is used in conjunction with a plurality of buffer boxes 501. Specifically, the wind dust suction component 6 includes a dust conveying main pipe 601, which is fixedly installed on one side of the inner cavity of the plurality of support frames 3. The top of the dust conveying main pipe 601 is connected to a plurality of support tubes 602. Figure 1 and attached Figure 2 As shown, the support tube 602 is also arranged through the support frame 3, the back of the buffer box 501 is connected to the dust pipe 508, and the back of the dust removal tube 4 is provided with a second slide groove 402 adapted to the dust pipe 508. One end of the dust pipe 508 passes through the second slide groove 402 and is connected to the support tube 602.

[0036] As a preferred solution, in order to further reduce the escape of dust, a dust box 7 is fixedly installed on the top of the inner cavity of the support frame 3. The dust box 7 is arranged above the main conveyor belt 2. A plurality of dust collection holes 701 are opened on one side of the dust box 7, and the other side of the dust box 7 is connected to the dust conveying main pipe 601 through a pipe.

[0037] The advantage of the second embodiment over the first embodiment is that the dust collected in the buffer box 501 can be cleaned to ensure the long-term stable use of the buffer box 501, and the dust in the dust removal cylinder 4 and the dust on the main conveyor belt 2 can be absorbed to effectively alleviate the dust situation.

[0038] When in use, the dust conveying main pipe 601 is connected to the dust suction port of the external dust suction device, and the cold material conveyor belt 1 conveys the cold material to the dust removal cylinder 4. The cold material passes through a plurality of dust filter nets 502 in turn to reduce the speed and filter the dust, and then falls on the main conveyor belt 2. During the process, the filtered dust falls into the buffer box 501, passes through the dust pipe 508 and enters the support tube 602, and then falls into the dust conveying main pipe 601 and is sent out. At the same time, the dust on the main conveyor belt 2 passes through the dust suction hole 701 and enters the dust suction box 7, and then enters the dust conveying main pipe 601 and is sent out.

[0039] When the cold material falls on the buffer box 501, the buffer box 501 is squeezed, and the buffer box 501 drives the slide plate 503 to slide downward in the first slide groove 401. The slide plate 503 drives the balance block 504 to squeeze the spring 507 downward to achieve buffering of the falling cold material.
