Description

Technical Field

[0001] The present invention relates to the field of asphalt mixing equipment, and particularly to a hot aggregate bin of an asphalt mixture mixing equipment with a material distribution function. Background Art

[0002] In the field of asphalt mixture mixing equipment, a conventional hot aggregate bin generally can only store one kind of multi-sized sand and gravel aggregate at the same time, and only one formula of asphalt mixture can be produced with one-time storage of materials. If it is necessary to produce another formula of mixture, it is necessary to first stop the front-end feeding, empty all the aggregates in each aggregate bin, and then replace them with the sand and gravel aggregates required for another formula for re-batching and mixing. Since it is necessary to stop the machine for material replacement, the construction period is prolonged and huge cost waste is also caused. Summary of the Invention

[0003] To overcome the deficiencies in the prior art, the present invention discloses a hot aggregate bin of an asphalt mixture mixing equipment with a material distribution function, which includes a material distribution bin assembly, a material distribution flap assembly, a storage bin assembly, and a discharge port assembly. The present invention designs the material distribution bin assembly into a multi-bin body stacked in upper and lower layers, and a material distribution flap assembly that can be turned back and forth is installed between the upper and lower bin bodies. Each receiving bin in the upper layer corresponds to a front transition bin and a rear transition bin symmetrically arranged in the lower layer. At the same time, a number of front storage bins and rear storage bins are symmetrically arranged in the storage bin assembly, and the number of front storage bins and rear storage bins are docked with the number of front transition bins and rear transition bins. By turning the material distribution flap assembly back and forth, the aggregates in the receiving bin can be correspondingly distributed into different front transition bins and front storage bins or different rear transition bins and rear storage bins. Through the cooperation of the receiving bin receiving different formula aggregates in batches and the forward and backward turning of the material distribution flap assembly, different formula aggregates can be stored in the front and rear rows of storage bins at the same time, so as to achieve non-stop material replacement and alternately produce two different formula asphalt mixtures. The hot aggregate bin of the asphalt mixture mixing equipment with a material distribution function described in the present invention realizes non-stop material replacement by the material distribution flap assembly distributing different formula aggregates into a number of transition bins and storage bins in the front and rear rows, which can shorten the production period and save production costs.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] The hot aggregate bin of an asphalt mixture mixing equipment with a material distributing function is characterized in that: it includes a material distributing bin assembly, a material distributing flap assembly and a storage bin assembly. The material distributing bin assembly is provided with a material distributing bin body with an upper and lower layer structure. The material distributing bin body includes several receiving bins in the upper layer and several front transition bins and several rear transition bins symmetrically arranged on the front and rear sides in the lower layer. The storage bin assembly is placed below the material distributing bin assembly. The storage bin assembly is provided with a storage bin body for classifying and storing sand and gravel aggregates. The storage bin body is provided with several front storage bins and several rear storage bins corresponding one by one to the several front transition bins and several rear transition bins of the material distributing bin assembly.

The left and right side walls of each receiving bin are arc-shaped orifice plates with semi-circular arcs at the bottom. The radii of the semi-circular arcs at the bottoms of several arc-shaped orifice plates are the same.

[0008] The material distributing flap assembly includes a rotating shaft assembly, a buffer plate, a flap, an arc-shaped spacer plate and a driving assembly. The flap is a long flat plate. The buffer plate is a strip-shaped flat plate. Several buffer plates are transversely and vertically fixed on the front surface of the flap. The rotating shaft assembly includes a rotating shaft fixed on the back surface of the flap and a bearing seat with bearings at both ends. The driving assembly is a driving part with a reduction motor and a brake. The driving assembly is connected to the input shaft end of the rotating shaft of the rotating shaft assembly. The arc-shaped spacer plate is a semi-circular plate body longitudinally and vertically fixed on the front surface of the flap. The arrangement positions of several arc-shaped spacer plates correspond one by one to the positions of the lower ends of several arc-shaped orifice plates of the material distributing bin assembly. The material distributing flap assembly is locked on the material distributing bin assembly.

When the material distributing flap assembly rotates forward or backward, the aggregates at the lower funnel opening of the receiving bin can be distributed into the corresponding front transition bin or rear transition bin.

[0010] The hot aggregate bin of the asphalt mixture mixing equipment with a material distribution function further includes a discharge port assembly. The discharge port assembly is arranged below the storage bin assembly. The discharge port assembly is provided with a plurality of discharge bin openings with arc-shaped discharge doors corresponding to the front storage bin and the rear storage bin of the storage bin assembly one by one. A plurality of discharge doors are respectively fixed to the lower parts of the plurality of discharge bin openings, and the discharge doors can be turned up and down for closing and opening.

[0011] Both the front storage bin and the rear storage bin are funnel-shaped cavity bodies with the lower ends narrowing towards the middle. The lower funnel openings of the plurality of front storage bins and rear storage bins are respectively butted with the plurality of discharge bin openings of the discharge port assembly one by one.

[0012] The material distribution bin assembly further includes a first box-shaped frame. The material distribution bin body is fixed in the first box-shaped frame. The storage bin assembly further includes a second box-shaped frame. The storage bin body is fixed in the second box-shaped frame. The discharge port assembly further includes a third box-shaped frame. The discharge bin openings and the discharge doors are fixed in the third box-shaped frame.

[0013] The storage bin assembly is further provided with an overflow pipe. Each front storage bin and each rear storage bin are connected in series with the upper pipe orifice of the overflow pipe. The upper pipe orifice of the overflow pipe is arranged on one side of the upper opening of the front storage bin or the rear storage bin for discharging the aggregate overflowed after the front storage bin and the rear storage bin are full to the outside of the bin.

[0014] The storage bin assembly further includes a negative pressure pipe. The negative pressure pipe is connected into the bin bodies of the storage bin assembly and the material distribution bin assembly for decompressing the air in the bin.

[0015] As can be seen from the above description, the advantages of the hot aggregate bin of the asphalt mixture mixing equipment with a material distribution function provided by the present invention are as follows: The material distribution bin assembly is designed as a multi-bin body with upper and lower layers stacked, and a material distribution flap assembly that can be turned forward and backward is installed between the upper and lower bin bodies. The upper bin body is composed of a row of a plurality of receiving bins, while the lower bin body and the storage bin assembly are both provided with two rows of a plurality of transition bins and a plurality of storage bins in the front and rear. By receiving aggregates with different formulas in batches through the receiving bins and using the forward and backward turning cooperation of the material distribution flap assembly, different formulas of aggregates can be stored in the front and rear rows of storage bins, so as to realize the alternate production of two different formulas of asphalt mixture without stopping the machine, thereby shortening the production period and saving production costs.

The storage bin assembly 3 is provided with a storage bin body 32 for classifying and storing sand and gravel aggregates. The storage bin body 32 is provided with a plurality of front storage bins 321 and a plurality of rear storage bins 322 corresponding one-to-one to a plurality of front transition bins 122 and a plurality of rear transition bins 123 of the material distribution bin assembly 1.

Each front storage bin 321 and each rear storage bin 322 are connected in series with the upper pipe orifice of the overflow pipe 33. The upper pipe orifice of the overflow pipe 33 is placed on one side of the upper opening of the front storage bin 321 or the rear storage bin 322 for discharging the aggregates overflowed after the front storage bin 321 and the rear storage bin 322 are full of materials out of the bin.

In this embodiment, a powder bin is further arranged inside the second box-shaped frame 31 for storing the powder required for asphalt mixture mixing.

[0032] As Figure 1 , Figure 2 and Figure 5 shown in the figure, the discharge port assembly 4 of the present invention is fixedly connected below the storage bin assembly 3. The discharge port assembly 4 is provided with a plurality of discharge bin openings 42 with arc-shaped discharge doors 43 corresponding one-to-one to the front storage bins 321 and the rear storage bins 322 of the storage bin assembly 3.

[0033] As Figure 9 shown in the figure, when the material distribution flap assembly 2 of the present invention rotates forward to make the flap tilt forward, the aggregates in each receiving bin 121 in the upper part of the material distribution bin assembly 1 can be correspondingly distributed into each front transition bin 122 in the lower front row.

[0034] As Figure 10 shown in the figure, when the material distribution flap assembly 2 of the present invention rotates backward to make the flap tilt backward, the aggregates in each receiving bin 121 in the upper part of the material distribution bin assembly 1 can be correspondingly distributed into each rear transition bin 123 in the lower rear row.

[0035] The method for using the hot aggregate bin of the asphalt mixture mixing equipment with a material distribution function according to the present invention is as follows:

[0036] When it is necessary to produce asphalt mixture of the first formula, first command the driving assembly 25 of the material distribution flap assembly 2 to rotate forward to make the flap 23 tilt forward, and then put gravel aggregates of different particle sizes of the first formula into each receiving bin 121 at the upper part of the material distribution bin assembly 1. At this time, the aggregates in each receiving bin 121 at the upper part can be correspondingly distributed into each front transition bin 122 in the front row at the lower part and directly enter each front storage bin 321 of the storage bin assembly 3 corresponding to each front transition bin 122 in the front row and the discharge bin opening 42 of the corresponding discharge port assembly 4. When the front storage bin 321 is full and aggregates overflow from the overflow pipe 33, the feeding of the aggregates of the first formula into the receiving bin 121 can be stopped.

[0037] Before mixing the asphalt mixture of the first formula, just open the discharge door 43 below the corresponding discharge bin opening 42 to discharge the material, and after metering, it is put into the mixer to be mixed into the asphalt mixture.

[0038] If it is necessary to quickly switch production to produce asphalt mixture of the second formula, command the driving assembly 25 of the material distribution flap assembly 2 to rotate backward to make the flap 23 tilt backward, and then put aggregates of different particle sizes of the second formula into each receiving bin 121 at the upper part of the material distribution bin assembly 1. The material distribution flap assembly 2 correspondingly distributes the aggregates at this time into each rear transition bin 123, rear storage bin 322 in the rear row and the corresponding discharge bin opening 42, and then the asphalt mixture of the second formula can be quickly produced.

[0039] For the hot aggregate bin of the asphalt mixture mixing equipment with a material distribution function according to the present invention, the material distribution flap assembly distributes aggregates of different formulas into several transition bins and storage bins in the front and rear rows to realize non-stop material change, which can shorten the production period and save production costs.

[0040] In the description of the present invention, words such as "first", "second", "third" are used to define positions. The use of "first", "second", "third" is only for the convenience of simplifying the description and has no specific meaning of sequence, unless "first", "second", "third" are specially stated.
