Description

Technical Field

[0001] The utility model relates to the field of batching devices, in particular to an efficient batching device for asphalt mixture mixing. Background Technique

[0002] Asphalt concrete is the main material for road construction, which is mainly made by stirring and mixing asphalt with raw materials such as sand, gravel and mineral powder in proportion. The granular materials such as sand, gravel and mineral powder can be collectively referred to as aggregates, and the aggregates play a role in improving the strength and stability of asphalt concrete.

[0003] In the process of producing and processing asphalt concrete, it is necessary to proportion and stir different types of aggregates according to the type and particle size of the aggregates, that is, to weigh various aggregates by using a metering hopper, and determine the mixing ratio of the aggregates by weight.

[0004] With the rapid development of China's economy, the quality requirements for road surfaces are increasing day by day. The standard 5 aggregate bins have become 6 or more aggregate bins. The increase in the number of aggregate bins leads to an increase in the batching time. If the original method is still used, that is, by changing the sequence of the aggregate bins to make the aggregates fully mixed in the stone metering hopper to shorten the mixing time, the effect of increasing the output will decline.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following will further elaborate on the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1-5 shown, the present utility model provides an efficient batching device for asphalt mixture mixing, including a first stone metering hopper 1, a second stone metering hopper 2 and six aggregate bins 3. The structures of the first stone metering hopper 1 and the second stone metering hopper 2 are completely the same. The six aggregate bins 3 are divided into a first bin 301, a second bin 302, a third bin 303, a fourth bin 304, a fifth bin 305 and a sixth bin 306.

[0028] The first bin 301, the second bin 302 and the third bin 303 are arranged above the second stone metering hopper 2. The fourth bin 304, the fifth bin 305 and the sixth bin 306 are arranged above the first stone metering hopper 1. A pair of discharge doors 5 are provided at the bottom of each aggregate bin 3 except the fourth bin 304. The bottom end of the discharge door 5 communicates with the corresponding first stone metering hopper 1 or the second stone metering hopper 2. The discharge doors 5 of the first bin 301, the second bin 302 and the third bin 303 lead into the second stone metering hopper 2. The discharge doors 5 of the fifth bin 305 and the sixth bin 306 lead into the first stone metering hopper 1. Each pair of discharge doors 5 includes a small discharge door 501 and a large discharge door 502.

[0029] Two pairs of discharge doors 5 are provided between the fourth bins 304, and the two pairs of discharge doors 5 communicate with the first stone metering hopper 1 and the second stone metering hopper 2 respectively.

[0030] A pair of discharge doors 4 are provided at the bottom ends of the first stone metering hopper 1 and the second stone metering hopper 2. The metered raw materials are discharged through the discharge doors 4. Two S-type tensile sensors 8 are provided on the front and rear sides of the first stone metering hopper 1 and the second stone metering hopper 2. The S-type tensile sensors 8 play a role in calculating the weight.

[0031] By changing one measuring hopper in the prior art into two measuring hoppers, namely the No. 1 stone measuring hopper 1 and the No. 2 stone measuring hopper 2, and there are two sets of discharging doors 5 at the bottom of 204. When 6 aggregate bins 3 are needed, the No. 1 stone measuring hopper 1 and the No. 2 stone measuring hopper 2 are used for batching at the same time. The No. 1 stone measuring hopper 1 is batch-fed by the No. 4 bin 304, the No. 5 bin 305 and the No. 6 bin 306, and the No. 2 stone measuring hopper 2 is batch-fed by the No. 1 bin 301, the No. 2 bin 302 and the No. 3 bin 303. The No. 1 stone measuring hopper 1 and the No. 2 stone measuring hopper 2 are batch-fed at the same time, and the time for batch-feeding 6 kinds of materials is reduced to the time for batch-feeding 3 kinds of materials, and the time is shortened by half. Moreover, the 3 kinds of aggregates corresponding to the No. 1 stone measuring hopper 1 and the No. 2 stone measuring hopper 2 rely on the order of the discharging large door 502 and the discharging small door 501 to make the 3 kinds of materials fully mixed, further shortening the mixing time;

[0032] When laying low-grade residential roads and only using less than 4 kinds of aggregates for batching, the No. 2 stone measuring hopper 2 can be used for separate measurement. For 4 kinds of aggregates and below, the order of large and fine materials is adjusted so that the 4 kinds of aggregates and below are fully fused in the No. 2 stone measuring hopper 2, shortening the mixing time and increasing the equipment production capacity.

[0033] In order to make the aggregates falling from the discharging doors 5 at different positions evenly distributed inside the No. 1 stone measuring hopper 1 or the No. 2 stone measuring hopper 2, as Figure 1 、 2 、as shown in 5, a distribution component 7 is provided inside both the No. 1 stone measuring hopper 1 and the No. 2 stone measuring hopper 2, and the distribution component 7 is located at the bottom of the corresponding discharging door 5;

[0034] The distribution component 7 includes a support plate 703, and a plurality of material leakage grooves 704 penetrating through the support plate 703 are formed on the support plate 703.

[0035] The bottom end of the support plate 703 is fixedly provided with an adjusting shaft 702, and motors 701 for driving the corresponding adjusting shaft 702 to rotate are fixedly provided on the front sides of both the No. 1 stone measuring hopper 1 and the No. 2 stone measuring hopper 2.

[0036] Whether it is the No. 1 stone measuring hopper 1 or the No. 2 stone measuring hopper 2, there are corresponding multiple discharging doors 5. Taking the No. 1 stone measuring hopper 1 as an example, the positions of the respective discharging doors 5 inside the No. 1 stone measuring hopper 1 are different in the left-right direction. When the aggregate is discharged into the No. 1 stone measuring hopper 1 through the left discharging door 5, the motor 701 drives the adjusting shaft 702 to rotate and drives the support plate 703, so that the support plate 703 is inclined and the left end of the support plate 703 is upturned. Therefore, the aggregate falling from the left discharging door 5 will fall on the higher end of the support plate 703 and slide down along the inclined support plate 703, and the aggregate falls to various positions inside the No. 1 stone measuring hopper 1 through the respective material leakage grooves 704 during the sliding process, thereby dispersing the falling aggregate in the No. 1 stone measuring hopper 1. The principle of discharging through the right discharging door 5 is the same;

[0037] When the discharge gate 5 in the middle position discharges aggregate, the motor 701 can be used to control the support plate 703 to tilt and swing left and right, and the fallen aggregate can be dispersed to both sides along the support plate 703. The distribution component 7 can make the aggregates dropped from each discharge gate 5 be evenly dispersed in the No. 1 stone measuring bucket 1 without being offset due to the offset of the position of the discharge gate 5, which helps to mix the aggregates evenly.

[0038] In order to make the aggregates further mixed, Figures 1-4 As shown, a striking assembly 6 is provided on one side of the No. 1 stone material measuring bucket 1 and the No. 2 stone material measuring bucket 2, and the striking assembly 6 includes a fixed shaft 605, and both ends of the fixed shaft 605 are provided with end plates 602 through a rotating shaft, and the end plates 602 are fixed to the outer ends of the corresponding No. 1 stone material measuring bucket 1 or No. 2 stone material measuring bucket 2;

[0039] An iron extension plate 603 is fixedly provided at the top of the fixed shaft 605 , and an electromagnet 601 is provided at one side of the iron extension plate 603 . The electromagnet 601 is fixedly provided on the corresponding No. 1 stone material measuring bucket 1 or No. 2 stone material measuring bucket 2 .

[0040] Torsion springs 606 are fixedly provided at both ends of the fixed shaft 605, and the torsion springs 606 are connected between the end plate 602 and the fixed shaft 605. A driving arm 604 is fixedly provided at the bottom end of the fixed shaft 605, and a knocking hammer 607 is fixedly provided at the bottom end of the driving arm 604. A layer of rubber with a buffering effect can be wrapped around the outer end of the knocking hammer 607.

[0041] In the idle state, the torsion spring 606 is in a tightened state, and the percussion hammer 607 contacts the outer end of the No. 1 stone measuring bucket 1 or the No. 2 stone measuring bucket 2. Taking the No. 1 stone measuring bucket 1 as an example, during the batching process, the electromagnet 601 is intermittently energized. The energized electromagnet 601 will absorb the iron extension plate 603, so that the iron extension plate 603 moves and drives the fixed shaft 605 to rotate, and the torsion spring 606 is further tightened. The fixed shaft 605 simultaneously drives the driving arm 604 and the percussion hammer 607, so that the percussion hammer 607 is away from the No. 1 stone measuring bucket. Measuring bucket 1, then the electromagnet 601 is powered off, the elastic force of the torsion spring 606 will be released, driving the fixed shaft 605 to rotate in the opposite direction, and making the driving arm 604 drive the knocking hammer 607, so that the knocking hammer 607 knocks on the outer end of the No. 1 stone measuring bucket 1, thereby continuously energizing and deenergizing the electromagnet 601, and the knocking hammer 607 will continuously knock on the No. 1 stone measuring bucket 1, causing the No. 1 stone measuring bucket 1 to vibrate, so that the smaller aggregate in the No. 1 stone measuring bucket 1 falls downward into the gap between the larger aggregate, thereby promoting the uniform mixing of various aggregates.

[0042] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
