Description

Technical Field

[0001] The utility model relates to the technical field of asphalt concrete stirring and mixing, in particular to an asphalt aggregate proportion mixing device. Background Art

[0002] Asphalt concrete is widely used in urban road construction and highway construction. Existing asphalt concrete is generally made of asphalt binder and asphalt aggregate by heating and stirring. Asphalt aggregate is composed of gravels of different particle sizes in a certain proportion. According to the final strength requirements of asphalt concrete, gravels of different particle sizes need to be strictly proportioned in the proportioning process. The proportioning mentioned above actually requires mixing according to the volume ratio of each gravel. The existing asphalt aggregate usually controls the amount of aggregates of various particle sizes by weighing during the proportioning process. However, in the actual production process, due to the difference in the material of the gravel (different materials have different densities of each gravel), the volume ratio of each gravel in the mixed asphalt concrete will be greatly deviated from the design ratio, which will cause the final mixed asphalt concrete to fail to meet the designed strength standard, seriously affecting the quality of the project, and even causing huge waste due to the scrapping of materials. In addition, the existing production method of production by weighing cannot be carried out continuously, which greatly affects the production efficiency of asphalt concrete.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0038] Example:

[0039] See also Figure 1-Figure 7 The present embodiment provides an asphalt aggregate proportion mixing device, comprising a frame 1, a first material storage and conveying device 2, a second material storage and conveying device 3 and a mixing device 4, wherein the first material storage and conveying device 2, the second material storage and conveying device 3 and the mixing device 4 are all installed on the frame 1, and the mixing device 4 is arranged at the lower discharge port position of the first material storage and conveying device 2 and the second material storage and conveying device 3; the first material storage and conveying device 2 comprises a first material storage hopper 21 and a first material control mechanism 22, the first material control mechanism 22 is arranged at the material discharge position at the lower end of the first material storage hopper 21, the upper end of the first material control mechanism 22 is connected to the lower end of the first material storage hopper 21, and the lower end of the first material control mechanism 22 is connected to the frame 1; the second material storage and conveying device 3 comprises a second material storage hopper 31 and a second material control mechanism 32, the second material control mechanism 32 is arranged at the lower end of the second material storage hopper 31, the upper end of the second material control mechanism 32 is flexibly connected to the lower end of the second material storage hopper 31 The lower end of the second material controlling mechanism 32 is connected to the frame 1; the first material controlling mechanism 22 includes a first material controlling hopper 221, a first gate group 222 and a first vibration component 223, the first material controlling hopper 221 is arranged below the first storage hopper 21, and the feed inlet of the first material controlling hopper 221 is connected to the discharge end of the first storage hopper 21, the first gate group 222 is arranged at the discharge port of the first material controlling hopper 221, and the first vibration component 223 is arranged on the outer wall of the first material controlling hopper 221; the second material controlling mechanism 32 includes a second material controlling hopper 321, a second gate group 322 and a second vibration component 323, the second material controlling hopper 321 is arranged below the second storage hopper 31, and the feed inlet of the second material controlling hopper 321 is connected to the discharge end of the second storage hopper 31, the second gate group 322 is arranged at the discharge port of the second material controlling hopper 321, and the second vibration component 323 is arranged on the outer wall of the second material controlling hopper 321.

[0040] Specifically, the first storage hopper 21 and the second storage hopper 31 are fixedly connected to the upper part of the frame 1. The mixing device 4 is installed at the lower part of the frame 1, and the input port of the mixing device 4 faces upward, so as to receive the gravel output from the first material control mechanism 22 and the second material control mechanism 32, and mix and stir them. The lower end of the mixing device 4 is provided with a discharge port for convenient material discharge. The mixing device 4 includes a shell 41, a spiral stirring paddle 42 and an asphalt injection pipe 43. The shell 41 is fixedly connected to the frame 1, the spiral stirring paddle 42 is rotatably connected to the shell 41, the asphalt injection pipe 43 is fixedly connected to the upper part of the shell 41, and the injection port of the asphalt injection pipe 43 extends into the shell 41.

[0041] It can be understood that when gravel of different particle sizes needs to be mixed, the two types of gravel of different particle sizes are loaded into the first storage hopper 21 and the second storage hopper 31 respectively; the gravel in the first storage hopper 21 flows to the first material control hopper 221 of the first material control mechanism 22 under the action of gravity, and is discharged downward from the first gate group 222, and the flow rate of the gravel discharged downward is controlled by controlling the opening of the first gate group 222. The larger the opening, the larger the flow rate of the gravel discharged downward from the first gate group 222; the gravel in the second storage hopper 31 flows to the second material control hopper 321 of the second material control mechanism 32 under the action of gravity, and is discharged downward from the second gate group 322, and the flow rate of the gravel discharged downward is controlled by controlling the opening of the second gate group 322. The larger the opening, the larger the flow rate of the gravel discharged downward from the first gate group 222. It can be known that when the mixing ratio of two gravels of different particle sizes needs to be adjusted, it is only necessary to control the relative opening of the first gate group 222 and the second gate group 322 to accurately control the volume ratio of the mixture of the two gravels of different particle sizes, thereby ensuring the stable performance of the mixed asphalt concrete.

[0042] It should be noted that gravel of different particle sizes are respectively loaded in the first control hopper 221 and the second control hopper 321. When the gravel in the first control hopper 221 flows out from the first gate group 222 and the gravel in the second control hopper 321 flows out from the second gate group 322, there may be a situation where the gravel is stuck. If stuck, the flow rate of the gravel flowing out from the first gate group 222 or the second gate group 322 will be unstable, which will affect the mixing ratio of the asphalt concrete. The first control hopper 221 is vibrated by the first vibration component 223, and the second control hopper 321 is vibrated by the second vibration component 323, so as to enhance the fluidity of the gravel in the first control hopper 221 and the second control hopper 321, enhance the stability of the flow rate of the gravel flowing out from the first gate group 222 or the second gate group 322, and prevent the occurrence of stuck, so as to control the volume ratio of the two gravels by the flow ratio to ensure the stability of the mixing ratio of the asphalt concrete. Of course, it is worth noting that a plurality of first material storage and feeding devices 2 can be arranged, so as to facilitate mixing gravels of various different particle sizes according to volume proportions.

[0043] It should also be noted that gravels of different particle sizes enter the housing 41 of the mixing device 4, are mixed and transported under the action of the spiral stirring paddle, the asphalt injection pipe 43 sprays the heated asphalt into the housing 41, and the spiral stirring paddle stirs and transports the mixed asphalt concrete, so that the mixed asphalt concrete moves toward the discharge port on the housing 41, and finally the mixed asphalt concrete is discharged from the discharge port on the housing 41. Because each process is carried out continuously, the entire production process can be operated continuously, which improves production efficiency (the existing equipment can only stir one pot at a time, and the production efficiency is low).

[0044] Furthermore, the first gate group 222 includes a first proportional regulating gate 2221 and a first flow regulating gate 2222, the first proportional regulating gate 2221 and the first flow regulating gate 2222 are connected in series at the discharge port of the first control hopper 221, and the first proportional regulating gate 2221 and the first flow regulating gate 2222 are arranged perpendicular to each other; the second gate group 322 includes a second proportional regulating gate 3221 and a second flow regulating gate 3222, the second proportional regulating gate 3221 and the second flow regulating gate 3222 are connected in series at the discharge port of the second control hopper 321, and the second proportional regulating gate 3221 and the second flow regulating gate 3222 are arranged perpendicular to each other; the asphalt aggregate proportion mixing device also includes a connecting rod 5, a fixed seat 6 and a driving mechanism 7, the first end of the connecting rod 5 is fixedly connected to the first flow regulating gate 2222, and the second end of the connecting rod 5 is fixedly connected to the second flow regulating gate 3222; the first end of the fixed seat 6 is fixedly connected to the first flow regulating gate 2222, and the second end of the fixed seat 6 is fixedly connected to the second flow regulating gate 3222; the fixed end of the driving mechanism 7 is fixed on the fixed seat 6, and the driving end of the driving mechanism 7 is fixedly connected to the connecting rod 5.

[0045] Specifically, the first proportional regulating gate 2221 and the second proportional regulating gate 3221 are arranged in the horizontal direction, and the first flow regulating gate 2222 and the second flow regulating gate 3222 are arranged in the longitudinal direction. The first proportional regulating gate 2221 and the second proportional regulating gate 3221 are used to control the horizontal opening of the first gate group 222 and the second gate group 322 respectively, and the first flow regulating gate 2222 and the second flow regulating gate 3222 are used to control the longitudinal opening of the first gate group 222 and the second gate group 322 respectively.

[0046] It can be understood that there is no connection between the first proportional regulating gate 2221 and the second proportional regulating gate 3221, and the openings of the first proportional regulating gate 2221 and the second proportional regulating gate 3221 can be conveniently controlled, so that the flow rate ratio of the corresponding gravel outflow is controlled by the ratio of the openings of the first proportional regulating gate 2221 and the second proportional regulating gate 3221, and then the volume ratio of the two types of gravel is controlled; and the first flow regulating gate 2222 and the second flow regulating gate 3222 are connected at the same time through the connecting rod 5, so that when the driving mechanism 7 drives the connecting rod 5 to move, the openings of the first flow regulating gate 2222 and the second flow regulating gate 3222 are simultaneously controlled, because the openings of the first flow regulating gate 2222 and the second flow regulating gate 3222 are simultaneously increased or decreased, and the first flow regulating gate 2222 and the second flow regulating gate 3222 are simultaneously increased or decreased, the flow rate ratio of the two types of gravel remains unchanged, but the size of the flow increases or decreases, thereby realizing the regulation of the total flow.

[0047] It should be noted that the driving mechanism 7 is an electric push rod, which drives the connecting rod 5 to move by extending or retracting the electric push rod, thereby achieving simultaneous adjustment of the first flow regulating gate 2222 and the second flow regulating gate 3222.

[0048] Further, the first proportional adjustment gate 2221 includes a first gate plate 2223 and a first locking member 2224. The first material control hopper 221 is provided with a first slot, the first gate plate 2223 is inserted into the first slot, and the first locking member 2224 is used to position and lock the first gate plate 2223 in the first slot. In this embodiment, the first locking member 2224 is a screw, the first material control hopper 221 is provided with a threaded hole, the screw is threadedly connected in the threaded hole, and the head of the screw abuts against the first gate plate 2223, and the first gate plate 2223 is positioned by the screw and the first gate plate 2223 being tightly abutted.

[0049] It can be understood that when the opening of the first proportional adjustment gate 2221 needs to be adjusted, the screw is loosened and the first gate plate 2223 is moved to move the first gate plate 2223 into or out of the first slot. After the relative position of the first gate plate 2223 relative to the first slot is adjusted, the screw is tightened to position and fix the first gate plate 2223 in the first slot. The opening of the first proportional adjustment gate 2221 can be conveniently adjusted by the cooperation of the first locking member 2224 and the first gate plate 2223.

[0050] It should be noted that the second proportional regulating gate 3221 has substantially the same structure as the first proportional regulating gate 2221 , which will not be described in detail herein.

[0051] Furthermore, the first flow regulating gate 2222 also includes a second gate plate 2225, a second slot is provided on the first material control hopper 221, the second slot and the first slot are distributed up and down, and the directions of the first slot and the second slot are perpendicular to each other, and the second gate plate 2225 is inserted in the second slot; the second flow regulating gate 3222 also includes a third gate plate 3223, a third slot is provided on the second material control hopper 321, and the third gate plate 3223 is inserted in the third slot; the first end of the connecting rod 5 is fixedly connected to the second gate plate 2225, and the second end of the connecting rod 5 is fixedly connected to the third gate plate 3223.

[0052] It can be understood that the connecting rod 5 is driven to move by the driving mechanism 7, thereby simultaneously driving the second gate plate 2225 and the third gate plate 3223 to move, thereby achieving the adjustment of the flow of the first flow regulating gate 2222 and the second flow regulating gate 3222 without changing the ratio of the first flow regulating gate 2222 and the second flow regulating gate 3222.

[0053] Furthermore, scale lines are arranged on both the first gate plate 2223 and the second gate plate 2225 , and a plurality of scale lines are arranged, and the plurality of scale lines are evenly spaced along the length direction of the first gate plate 2223 or the second gate plate 2225 .

[0054] It can be understood that the opening of the corresponding gate adjustment can be easily known through the scale lines.

[0055] Furthermore, the first material control mechanism 22 also includes a flexible material guide hopper 224 and an elastic member 225, the first end of the flexible material guide hopper 224 is fixedly connected to the discharge port of the first storage hopper 21, and the second end of the flexible material guide hopper 224 is fixedly connected to the inlet of the first material control hopper 221; the first end of the elastic member 225 is fixedly connected to the first material control hopper 221, and the second end of the elastic member 225 is fixedly connected to the frame 1.

[0056] It can be understood that, by setting the flexible guide hopper 224, the first vibrating member can easily drive the first control hopper 221 to vibrate, and at the same time, the flexible guide hopper 224 cannot transmit vibration, so the vibration is concentrated on the first control hopper 221, which plays a role in saving energy, and secondly prevents the vibration from being transmitted to other components and causing damage to other components. The first control hopper 221 is supported by the elastic member 225, and at the same time, the elastic member 225 has a certain buffering effect, which reduces the vibration transmitted to the frame 1 and prevents the vibration from causing damage to the frame 1 and other components on the frame 1. It should be noted that in this embodiment, the elastic member 225 is a spring. In other embodiments, the elastic member 225 can also be a rubber block or an air bag, etc., which can play a supporting and buffering role. Parts or structures.

[0057] Furthermore, the first material control mechanism 22 further includes a fastener 226, and the first end of the flexible material guide hopper 224 is fixedly connected to the discharge port of the first material storage hopper 21 through the fastener 226, and the second end of the flexible material guide hopper 224 is fixedly connected to the inlet of the first material control hopper 221 through the fastener 226. The first end of the flexible material guide hopper 224 is covered on the outside of the first material storage hopper 21, and the second end of the flexible material guide hopper 224 extends into the interior of the first material control hopper 221 and covers the inner wall at the entrance of the first material control hopper 221.

[0058] It can be understood that when gravel enters the flexible guide hopper 224 from the first storage hopper 21, the gravel can easily enter the flexible guide hopper 224 from the first storage hopper 21 because the flexible guide hopper 224 is covered outside the first storage hopper 21, and the gravel will not remain between the first storage hopper 21 and the flexible guide hopper 224; if the flexible guide hopper 224 is inside the first storage hopper 21, an upward step will be formed between the first storage hopper 21 and the flexible guide hopper 224, and this step is likely to block the gravel, which is not conducive to the smooth flow of gravel into the flexible guide hopper 224, and the gravel is likely to cause wear to the flexible guide hopper 224 at the step, affecting the life of the flexible guide hopper 224. Similarly, the second end of the flexible guide hopper 224 extends into the interior of the first control hopper 221, so that the gravel can smoothly enter the first control hopper 221 from the flexible guide hopper 224.

[0059] Furthermore, the first material control mechanism 22 also includes a first material guide hopper 227, which is arranged below the first material control hopper 221, and the feed end of the first material guide hopper 227 is connected to the discharge end of the first material control hopper 221; the second material control mechanism 32 also includes a second material guide hopper 324, which is arranged below the second material control hopper 321, and the feed end of the second material guide hopper 324 is connected to the discharge end of the second material control hopper 321; the discharge end of the first material guide hopper 227 and the discharge end of the second material guide hopper 324 are both arranged at an angle, and the extension line of the discharge end of the first material guide hopper 227 intersects with the extension line of the discharge end of the second material guide hopper 324.

[0060] It can be understood that the gravel flowing out of the first material control mechanism 22 is guided by the first material guide hopper 227, and the gravel flowing out of the second material control mechanism 32 is guided by the second material guide hopper 324, so that the gravel flowing out of the two converge and collide above the stirring device to achieve preliminary mixing, and then fall into the shell 41 of the stirring device to be mixed again, so as to improve the mixing efficiency.

[0061] Specifically, in the present embodiment, the flexible material guide hopper 224 is made of rubber. In other embodiments of the present application, the flexible material guide hopper 224 may also be made of one of the materials selected from the group consisting of silicone and polyurethane.

[0062] The working principle of the technical solution of the utility model is as follows:

[0063] The gravels of two different particle sizes are placed in the first storage hopper 21 and the second storage hopper 31 respectively, and the openings of the first proportional regulating gate 2221 and the second proportional regulating gate 3221 are adjusted to the set ratio, and the first vibration component 223 and the second vibration component 323 are turned on, and then the driving mechanism 7 drives the connecting rod 5 to drive the first flow regulating gate 2222 and the second flow regulating gate 3222 to open at the same time, and the gravels in the second storage hopper 31 pass through the second control gate in sequence. The hopper 321 and the second guide hopper 324 enter the housing 41 of the stirring device. The gravel flowing out of the first guide hopper 227 and the gravel in the second guide hopper 324 collide in the air, are preliminarily mixed, and fall into the housing 41, and are then stirred and mixed by the spiral stirring blades. During the stirring process of the spiral stirring blades, the asphalt injection pipe 43 sprays asphalt into the housing 41, so that the asphalt and gravel of different particle sizes are mixed together, and the asphalt is transported toward the discharge port on the housing 41 while stirring by the spiral stirring blades until it is discharged from the discharge port.
