Description

Asphalt concrete aggregate premix mechanism

Technical Field

The utility model belongs to the technical field of asphalt concrete compounding equipment, especially, relate to an asphalt concrete aggregate premix mechanism.

Background

The asphalt concrete is commonly called as asphalt concrete, and is a mixture prepared by manually selecting mineral aggregate with a certain gradation composition, broken stone or crushed gravel, stone chips or sand, mineral powder and the like, and mixing the mineral aggregate, the broken stone or crushed gravel, the stone chips or sand, the mineral powder and a certain proportion of road asphalt material under strictly controlled conditions. When the asphalt concrete is stirred, the primarily prepared cold aggregate is usually added into a drying cylinder, the hot aggregate is formed through drying and heating, then the hot aggregate is subjected to vibration screening, and the hot aggregate and the measured filler are added into a stirrer together and stirred to form the asphalt mixture through storage and measurement of a hot material bin. At present, no matter cold or hot aggregate, the materials are required to be mixed before entering the stirrer, and the materials are usually simply mixed, so that the materials are completely mixed by the stirrer after entering the stirrer and cannot be uniformly mixed in a short time, and therefore, a premixing mechanism before stirring is required to do front work.

Disclosure of Invention

In view of the not enough of above-mentioned prior art, the utility model aims to provide an asphalt concrete aggregate mixes feed mechanism in advance mixes to multiple material before the stirring, can raise the efficiency, improves product quality.

For solving the above technical problem, the utility model discloses the technical scheme who adopts is:

the utility model relates to a bituminous concrete aggregate premix mechanism has and adds feed bin and blending bunker, it is provided with latticed bulk cargo layer to add the feed bin bottom, and bulk cargo layer top is equipped with pneumatic interlayer, is provided with the compounding wheel that four groups are concave arc and arrange in the blending bunker, the blending bunker bottom is provided with the hob, and blending bunker bottom one side has discharging channel, and the discharging channel below is provided with the unloading valve.

The utility model discloses a pneumatic interlayer is two parallel opening doors, and pneumatic interlayer is driven by first cylinder.

The utility model discloses a vibrating device is disposed outside the lower part of a feeding bin.

The utility model discloses an among the four group's mixing wheel, clockwise toward the blending bunker intermediate position rotation of two sets of mixing wheels in left side, anticlockwise toward the blending bunker intermediate position rotation of two sets of mixing wheels in right side.

The material of the mixing wheel of the utility model adopts manganese alloy.

The utility model discloses a mixing bunker bottom still disposes the heating pipe.

The utility model discloses a unloading valve is driven by the second cylinder.

The utility model has the advantages that: each material accessible unloading ware stretches into the blowing in the feeding bin, opens pneumatic interlayer, and each material falls scattered through the bulk cargo layer of vibration and gets into the blending bunker, and each material is abundant compounding under the rotatory allotment of four group's mixing ball, and the ejection of compact is impeld by the hob at last, can make perfect premix material work before the stirring, improves asphalt concrete's production efficiency greatly, guarantees product quality.

Description of the drawings:

fig. 1 is a schematic structural diagram relating to the present invention.

The specific implementation mode is as follows:

the present invention will be further described with reference to the accompanying drawings.

Please refer to fig. 1, the utility model relates to an asphalt concrete aggregate mixes feed mechanism in advance has and adds feed bin 1 and blending bunker 2, it is provided with latticed bulk cargo layer 11 to add feed bin 1 bottom, and bulk cargo layer 11 top is equipped with pneumatic interlayer 3, and it has the bar opening that supplies pneumatic interlayer 3 business turn over to add feed bin 1 lateral part, and pneumatic interlayer 3 is parallel two divisions of doors, and pneumatic interlayer 3 is driven by first cylinder 31, when needing the unloading, and pneumatic interlayer 3 is opened toward two sides to first cylinder 31 drive, then the material can be through bulk cargo layer 11, in bulk cargo layer 11 department scatters whereabouts to blending bunker 2.

The outer side of the lower part of the feeding bin 1 is provided with a vibrating device 10, the vibrating device 10 is a vibrator, and one or more vibrating devices can be arranged to vibrate the bulk material layer 11, so that materials can be better dispersed and enter the mixing bin 2.

Be provided with four groups in the blending bunker 2 and be the compounding wheel 4 that concave arc was arranged, the compounding wheel 4 runs through blending bunker 2 through the shaft, by the motor drive outside blending bunker 2, has more applications among this prior art, does not do too much here and gives unnecessary details. Specifically, among four group's mixing wheel 4, two sets of mixing wheels on left side are rotatory clockwise toward 2 intermediate positions of blending bunker, two sets of mixing wheels on right side are rotatory counterclockwise toward 2 intermediate positions of blending bunker, four groups of mixing wheels 4 occupy 90% cross section in the blending bunker 2, only the interval between mixing wheel 4 to and have certain interval between mixing wheel 4 and the blending bunker 2, make the material that scatters to blending bunker 2 beat towards the centre and mix, get into blending bunker 2 bottom at last.

The mixing wheel 4 is made of manganese alloy, so that the mixing wheel has high rigidity and toughness and certain bearing capacity on high-quality materials, and the mixing wheel 4 is durable.

2 bottoms of blending bunker are provided with hob 21, 2 bottom one side of blending bunker has discharging channel 22, and discharging channel 22 below is provided with unloading valve 5, and unloading valve 5 is driven by second cylinder 51, and when the material of mixing is located 2 bottoms of blending bunker, when needing the ejection of compact, open unloading valve 5 through second cylinder 51, then hob 21 action impels the misce bene, makes the misce bene move toward discharging channel 22, is located the unloading by unloading valve 5 at last.
