Description

Technical Field

[0001] This utility model relates to the field of asphalt mixture technology, specifically to a mixing device for testing asphalt mixtures. Background Technology

[0002] Asphalt mixture is a composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, and mineral powder, and some also contain polymers and wood cellulose; different structures are formed by mixing these materials of different qualities and quantities, and they have different mechanical properties.

[0003] As shown in the announcement CN 114522555 B, a mixing device for testing asphalt mixtures includes a distributor, a cold aggregate bin, a drying cylinder, a hot aggregate bin, and a mixing cylinder connected in sequence. The distributor is connected to the cold aggregate bin via a connecting pipe. The cold aggregate bin is connected to the drying cylinder via a conveyor belt. The drying cylinder is connected to the hot aggregate bin via a conveyor. The hot aggregate bin is connected to the mixing cylinder via a conveyor pipe. This device does not have a circumferential double mixing structure, cannot perform large-scale mixing of asphalt mixtures, and has low finished product quality under small-scale mixing. It does not have a detachable control lever, and after long-term use, a large amount of residue will inevitably adhere to the surface of the mixing structure. If it is not cleaned and replaced regularly, it will affect the working efficiency of the device. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device for testing asphalt mixtures, so as to solve the problems mentioned in the background art.

The disassembly mechanism includes a threaded strip, a fixing block, a threaded groove, and a control rod. The threaded strip is arranged circumferentially at the bottom ends of the first and second sleeve rods, the fixing block is movably arranged on the outer side of the bottom ends of the first and second sleeve rods, the fixing block has a threaded groove inside, the threaded groove being movably connected to the threaded strip, and the control rod is movably arranged inside the bottom ends of the first and second sleeve rods.

[0007] Preferably, a number of stirring blades are fixedly provided on both sides of the bottom end of the control rod, and the setting of the stirring blades can fully stir and process the asphalt mixture.

[0008] Preferably, a drive motor is fixedly installed at the center of the top of the cap, and the bottom of the drive motor is movably connected to the first sleeve rod. The drive motor is started by connecting it through existing wiring, which enables the internal stirring device to perform circumferential stirring, resulting in greater stirring force.

[0009] Preferably, a number of positioning screws are movably arranged around the top of the cap, and a processing box is fixedly arranged at the bottom of the cap. An injection port is fixedly arranged on one side of the outside of the processing box. After processing is completed, the operator can rotate the positioning screws to disengage from the threaded hole, remove the cap from the processing box, and pour the asphalt mixture to be processed into the processing box through the injection port.

[0010] Preferably, the top of the processing box has several threaded holes around its circumference, which are movably connected to positioning screws. The bottom center of the processing box has a discharge port. The threaded holes are movably connected to the positioning screws, allowing the cover to be easily removed, and the processed asphalt mixture is discharged from the discharge port.

[0011] Preferably, a plurality of mounting blocks are fixedly arranged around the bottom of the processing box, and a support base is fixedly arranged at the bottom of the mounting blocks. A plurality of expansion screws are arranged at the bottom of the support base, and the support base is stably fixed to the ground by the expansion screws, thereby ensuring the overall stability of the device.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. A mixing device for testing asphalt mixtures. The device first securely fixes the support base to the ground using expansion bolts, ensuring overall stability. The asphalt mixture to be mixed is poured into the processing box through the injection port. The drive motor is then activated, causing the first sleeve rod to rotate. Since the first gear at the bottom of the first sleeve rod meshes with the second gear at the bottom of the second sleeve rod, and the second gear is movably connected to the rack inside the cover, the control rod at the bottom of the first sleeve rod, driven by the motor, drives the mixing blades to stir. The second sleeve rod, in turn, drives its control rod to rotate circumferentially around the cover, stirring the mixture. This device features a circumferential double-stirring structure, enabling wide-range stirring of the asphalt mixture with greater stirring force and more thorough product mixing.

[0014] 2. After processing, the operator can rotate the positioning screw to disengage from the threaded hole, remove the cover from the processing box, and then manually rotate the fixing block to loosen the sleeve holding the control rod. The control rod can then be quickly removed for replacement and cleaning. The detachable control rod will inevitably accumulate a lot of residue on its surface after long-term use. Regular disassembly, replacement and cleaning can ensure the working efficiency of the device. Attached Figure Description
