Description

Technical Field

[0001] This utility model relates to the field of road engineering construction technology, and in particular to a modular integrated equipment for a fully mobile 120t asphalt mixing plant. Background Technology

[0002] Currently, traditional asphalt mixing plants generally suffer from the following problems: the equipment is bulky and difficult to move as a whole after fixed installation, requiring disassembly and transportation, resulting in low efficiency and high cost of construction site relocation; the integration of various functional modules is low, installation and debugging are complex, and the site area occupied is large; it is also inconvenient to feed and batch materials in a certain proportion, which reduces the quality of asphalt mixing, and the mixing effect is poor, which easily leads to uneven mixing and affects the quality of asphalt mixing. Therefore, we propose a fully mobile 120t asphalt mixing plant modular integrated equipment to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned shortcomings and propose a fully mobile 120t asphalt mixing plant modular integrated equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A modular, fully mobile 120t asphalt mixing plant includes a base. Two mounting mechanisms are located on the top of the base, with an aggregate bin and an asphalt tank respectively mounted on the top of the base via these mechanisms. A weighbridge is fixedly connected to the top of the base, and a mixing drum is fixedly connected to the top of the weighbridge. A cover is fixedly connected to the top of the mixing drum, and a high-efficiency mixing and heating mechanism is installed between the cover and the mixing drum. Screw conveyors are fixedly connected to the bottom of both the aggregate bin and the asphalt tank. The two screw conveyors are connected to the inlet of the mixing drum via flanges. A flow meter is installed at the outlet of the left screw conveyor. A controller is fixedly connected to the top of the base, and a chassis system mechanism is located at the bottom of the base.

[0006] Specifically, the chassis system includes four hydraulic cylinders fixedly connected to the bottom of the base, and four movable wheels rotatably connected to the bottom of the base. A support base is fixedly connected to the output shaft of each hydraulic cylinder, and the hydraulic cylinder is electrically connected to the controller.

[0007] Specifically, the installation mechanism includes two mounting seats fixedly connected to the top of the base. The top of the mounting seats has four through holes, and brackets are movably inserted into the through holes. One side of the bracket has a threaded groove. The outer side of the mounting seats is threaded with four screws, which are threaded into the corresponding threaded grooves. The aggregate bin and the asphalt tank are respectively fixedly connected to the top of the four corresponding brackets.

[0008] Specifically, a heating ring is fixedly fitted on the outside of the asphalt tank, an agitator is fixedly connected to the top of the asphalt tank, and an upper temperature sensor is fixedly connected to one side of the asphalt tank.

[0009] Specifically, the high-efficiency stirring and heating mechanism includes two heating plates and a drive motor fixedly connected to the top of the cover. The two heating plates are respectively fixedly connected to the inner walls of both sides of the stirring drum. A main shaft is fixedly connected to the output shaft of the drive motor. A turntable is fixedly sleeved on the outer side of the main shaft. Two secondary shafts are rotatably connected to the top of the turntable. Driven teeth are fixedly connected to the top of the secondary shafts. An internal gear ring is fixedly connected to the inner wall of the cover. The internal gear ring meshes with the two driven teeth. An eccentric stirring frame is fixedly connected to the bottom of the secondary shafts.

[0010] Specifically, a stirring rod is fixedly connected to the main shaft.

[0011] Specifically, a lower temperature sensor is fixedly connected to the top of the stirring drum, and the heating plate, drive motor, and lower temperature sensor are all electrically connected to the controller.

[0012] Specifically, the bottom of the mixing drum is fixedly connected to a discharge pipe, and two traction plates are fixedly connected to one side of the base.

[0013] In this utility model, a modular integrated equipment for a fully mobile 120t asphalt mixing plant is described. The controller activates four hydraulic cylinders, which move the support base upwards and resets. A tractor connected to the plant is used to transport the equipment to the new site via road. Upon arrival, the four hydraulic cylinders are activated in reverse, causing the four support bases to move downwards and contact the ground, lifting the moving wheels off the ground. This provides stable support and fixation of the base, improving stability during asphalt mixing. The screws and threaded grooves in the installation mechanism allow for quick fixing of the aggregate bins and asphalt tanks. Flanges connect the two screw conveyors to the feed inlet of the mixing drum.

[0014] In this utility model, a modular integrated mobile 120t asphalt mixing plant is described. A screw conveyor on the left transports aggregate from the aggregate bin to the mixing drum. The weight of the aggregate is determined by a weighbridge. When the required weight is reached, the screw conveyor is shut off. The asphalt is then stirred by a mixer. A heating ring and an upper temperature sensor heat the asphalt to prevent condensation and ensure the fluidity of the hot melt asphalt. A screw conveyor on the right transports the hot melt asphalt to the mixing drum. A flow meter measures the amount of asphalt added. When the required weight is reached, the right screw conveyor is shut off. Aggregates and asphalt can then be added in a specific ratio to ensure the quality of the asphalt mixture.

[0015] In this utility model, a modular integrated equipment for a fully mobile 120t asphalt mixing plant can regulate the temperature inside the mixing drum by setting a heating plate and a lower temperature sensor, so as to heat the aggregate and asphalt and improve the mixing quality. The drive motor drives the rotation of the main shaft, turntable and multiple mixing rods. At the same time, the turntable drives two auxiliary shafts and eccentric mixing frame to revolve around the main shaft. During the revolution, under the action of the internal gear ring, the two driven teeth will rotate. The driven teeth drive the rotation of the auxiliary shaft and eccentric mixing frame, thereby driving the eccentric mixing frame to rotate eccentrically while revolving, which greatly improves the mixing effect. In addition, the mixing rods can stir and mix the materials at the bottom, further improving the mixing effect. After mixing, the asphalt is discharged from the discharge pipe.

[0016] This utility model has a reasonable structural design. The entire equipment can be transported by road and does not need to be disassembled during relocation, which is conducive to movement and transfer. After relocation, the device can be supported and fixed by hydraulic cylinders and support seats. The aggregate bins and asphalt tanks can be modularly connected and installed with the mixing drum, which improves the assembly efficiency. It can also feed and batch materials according to a certain ratio. With the eccentric mixing frame rotating around the center and the rotating mixing rod, the mixing effect is better and the quality of asphalt mixing is greatly improved. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A modular integrated mobile 120t asphalt mixing plant includes a base 1. Two mounting mechanisms 9 are installed on the top of the base 1, with an aggregate bin 10 and an asphalt tank 11 respectively mounted on the top of the base 1 via the two mounting mechanisms 9. A weighbridge 3 is fixedly connected to the top of the base 1, and a mixing drum 4 is fixedly connected to the top of the weighbridge 3. A cover 5 is fixedly connected to the top of the mixing drum 4. A high-efficiency mixing and heating mechanism 6 is installed between the cover 5 and the mixing drum 4. Screw conveyors 12 are fixedly connected to the bottom of both the aggregate bin 10 and the asphalt tank 11. The two screw conveyors 12 are connected to the inlet of the mixing drum 4 via flanges. A flow meter 18 is installed at the outlet of the left screw conveyor 12. A controller 2 is fixedly connected to the top of the base 1, and a chassis system mechanism 8 is installed at the bottom of the base 1.

[0024] Furthermore, refer to Figure 1 The chassis system mechanism 8 includes four hydraulic cylinders 82 fixedly connected to the bottom of the base 1, and four moving wheels 81 rotatably connected to the bottom of the base 1. A support seat 83 is fixedly connected to the output shaft of the hydraulic cylinder 82, and the hydraulic cylinder 82 is electrically connected to the controller 2.

[0025] The above scheme is adopted: the controller 2 starts four hydraulic cylinders 82, which drive the support seat 83 to move upward and reset. The tractor is connected to the traction plate 16 and transported to the new site by road. After arriving at the position, the four hydraulic cylinders 82 are started in reverse, so that the four support seats 83 move down to contact the ground and lift the moving wheel 81 off the ground, thereby stably supporting and fixing the base 1 and improving the stability during asphalt mixing.

[0026] Furthermore, refer to Figure 1 and Figure 4 The installation mechanism 9 includes two mounting seats 95 fixedly connected to the top of the base 1. The top of the mounting seat 95 has four through holes 92. A bracket 91 is movably inserted into the through holes 92. A threaded groove 93 is opened on one side of the bracket 91. Four screws 94 are threadedly connected to the outside of the mounting seat 95. The screws 94 are threadedly connected to the corresponding threaded grooves 93. The aggregate bin 10 and the asphalt tank 11 are respectively fixedly connected to the top of the four corresponding brackets 91.

[0027] The above solution facilitates the insertion of the bracket 91 through the through hole 92, and the bracket 91 is fixed by the screw 94 and the threaded groove 93, which in turn facilitates the installation and disassembly of the aggregate bin 10 and the asphalt tank 11.

[0028] Furthermore, a heating ring 13 is fixedly fitted on the outside of the asphalt tank 11, an agitator 14 is fixedly connected to the top of the asphalt tank 11, and an upper temperature sensor 15 is fixedly connected to one side of the asphalt tank 11, which facilitates heating and stirring of the asphalt, avoids condensation, and ensures the fluidity of the hot melt asphalt.

[0029] Furthermore, refer to Figures 1-3 The high-efficiency stirring and heating mechanism 6 includes two heating plates 68 and a drive motor 63 fixedly connected to the top of the cover 5. The two heating plates 68 are respectively fixedly connected to the inner walls of both sides of the stirring drum 4. A main shaft 61 is fixedly connected to the output shaft of the drive motor 63. A turntable 65 is fixedly sleeved on the outer side of the main shaft 61. Two secondary shafts 66 are rotatably connected to the top of the turntable 65. A driven gear 67 is fixedly connected to the top of the secondary shaft 66. An internal gear ring 64 is fixedly connected to the inner wall of the cover 5. The internal gear ring 64 meshes with the two driven gears 67. An eccentric stirring frame 69 is fixedly connected to the bottom of the secondary shaft 66. A stirring rod 62 is fixedly connected to the main shaft 61. A lower temperature sensor 7 is fixedly connected to the top of the stirring drum 4. The heating plates 68, the drive motor 63, and the lower temperature sensor 7 are all electrically connected to the controller 2.

[0030] The above scheme is adopted: by setting the heating plate 68 and the lower temperature sensor 7, the temperature inside the mixing drum 4 can be regulated to heat the aggregate and asphalt, thereby improving the mixing quality. The drive motor 63 drives the rotation of the main shaft 61, the turntable 65 and multiple stirring rods 62. At the same time, the turntable 65 drives the two auxiliary shafts 66 and the eccentric mixing frame 69 to revolve around the main shaft 61. During the revolution, under the action of the internal gear ring 64, the two driven teeth 67 will rotate. The driven teeth 67 drive the rotation of the auxiliary shafts 66 and the eccentric mixing frame 69, thereby driving the eccentric mixing frame to rotate eccentrically while revolving, which greatly improves the mixing effect. In addition, the stirring rods 62 can stir and mix the materials at the bottom, further improving the mixing effect. After mixing, the asphalt is discharged from the discharge pipe 17.

[0031] Furthermore, the bottom of the mixing drum 4 is fixedly connected to the discharge pipe 17, and two traction plates 16 are fixedly connected to one side of the base 1, which facilitates connection with traction equipment and also facilitates material discharge.

[0032] In this utility model, during use, the controller 2 activates four hydraulic cylinders 82, which drive the support base 83 to move upward and reset. The traction plate 16 connects to an external tractor, and the vehicle is transported to the new site by road. After reaching the location, the four hydraulic cylinders 82 are activated in reverse, causing the four support bases 83 to move downward and contact the ground, lifting the moving wheel 81 off the ground. This provides stable support and fixation for the base 1, improving the stability during asphalt mixing. The screws 94 and threaded grooves 93 in the installation mechanism 9 allow for quick fixing of the aggregate bin 10 and the asphalt tank 11. The flanges connect the two screw conveyors to the feed inlet of the mixing drum 4.

[0033] The parameters of controller 2 are calibrated via the PLC system. The aggregate in aggregate bin 10 is conveyed to mixing drum 4 via the left-side screw conveyor 12. The weight of the aggregate is determined by the weighbridge 3. When the required weight is reached, screw conveyor 12 is shut off. Asphalt is then stirred by agitator 14 (containing a stirring motor and impeller). The asphalt is heated by heating ring 13 and upper temperature sensor 15 to prevent condensation and ensure the fluidity of the asphalt melt. The right-side screw conveyor 12 conveys the asphalt melt to mixing drum 4. The amount of asphalt added is measured by flow meter 18. When the required weight is reached, right-side screw conveyor 12 is shut off. Aggregate and asphalt can then be added in a specific ratio to ensure the quality of the asphalt mixture. The temperature inside the mixing drum 4 can be regulated by the heating plate 68 and the lower temperature sensor 7 to heat the aggregate and asphalt, thereby improving the mixing quality. The drive motor 63 drives the rotation of the main shaft 61, the turntable 65 and multiple stirring rods 62. At the same time, the turntable 65 drives the two auxiliary shafts 66 and the eccentric mixing frame 69 to revolve around the main shaft 61. During the revolution, under the action of the internal gear ring 64, the two driven teeth 67 will rotate. The driven teeth 67 drive the rotation of the auxiliary shafts 66 and the eccentric mixing frame 69, thereby driving the eccentric mixing frame to rotate eccentrically while revolving, which greatly improves the mixing effect. The stirring rods 62 can also stir and mix the materials at the bottom, further improving the mixing effect. After mixing, the asphalt is discharged from the discharge pipe 17.
