Description

Technical Field

[0001] The utility model relates to the technical field of modified asphalt, in particular to a modified asphalt mixer. Background Art

[0002] Rubber powder is an important modified material for asphalt. After being added, many properties of asphalt are improved, such as reduced high-temperature deformation and enhanced low-temperature flexibility. The effect of rubber powder on asphalt is that rubber powder, as an admixture of asphalt, promotes the formation of asphalt structure. Rubber particles are distributed in the colloidal structure of asphalt to form a loose network, which ensures strength and reduces the high-temperature fluidity of asphalt, while improving the low-temperature deformation capacity of rubber asphalt.

[0003] Research and application in recent years have shown that high-parameter rubber asphalt mixtures can effectively improve the rutting of heavy-load traffic asphalt pavements and the cracking of asphalt pavements at low temperatures, and have good sound absorption effects, and can be used to build environmentally friendly noise-reducing pavements. In addition, the use of waste rubber powder to modify asphalt can not only improve the road performance of asphalt and asphalt mixtures, but also turn waste tires into treasures and solve environmental protection problems.

[0004] Existing high-parameter rubber asphalt usually uses a mixing tank to stir the rubber powder and the heated and melted base asphalt to fully mix the rubber powder and the base asphalt. However, since the melted asphalt has a certain viscosity, its fluidity is poor during the stirring process, resulting in poor mixing of the rubber powder and asphalt, which has a certain impact on the preparation of modified asphalt. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a modified asphalt mixer.

[0006] The utility model is achieved in this way:

Bushings are connected to the pair of fixing holes through bearings. A stirring rod is engaged at the bottom of the bushing. The stirring mechanism also comprises a driving mechanism. The output end of the driving mechanism is connected to the turntable. The driving mechanism drives the turntable and the bushing to rotate.

[0008] The beneficial effect of adopting the above further scheme is that the driving mechanism can drive the turntable and the sleeve to rotate simultaneously, so that the stirring rod can rotate and revolve at the same time, thereby fully stirring the material in the mixing barrel to improve the stirring effect, thereby improving the mixing degree of rubber powder and asphalt.

[0009] Furthermore, the driving mechanism includes a gear ring and a pair of gears. A cavity is opened at the bottom of the barrel cover, the gear ring is installed in the cavity, and the gear is installed on the top of the sleeve. The pair of gears and the gear ring are meshed and connected.

[0010] Furthermore, the driving mechanism also includes a first motor, which is installed at the top center of the barrel cover. The output end of the first motor is transmission-connected to a rotating shaft, and the bottom end of the rotating shaft is installed at the top center of the turntable.

[0011] The beneficial effect of adopting the above further scheme is that the first motor can drive the turntable to rotate, thereby driving the stirring rod to revolve, and while the turntable rotates, the gear moves on the gear ring, so that the gear drives the stirring rod to rotate, so as to achieve the purpose of the stirring rod rotating and revolving at the same time.

[0012] Furthermore, the stirring rod includes a plurality of convex rings and connecting rods, the convex rings and connecting rods are cross-connected, and the protrusion directions of adjacent convex rings are opposite.

[0013] The beneficial effect of adopting the above further solution is that, by using a plurality of convex rings with convexities in opposite directions, the contact area between the stirring rod and the material can be increased, thereby improving the mixing degree of the rubber powder and the asphalt.

[0014] Furthermore, a sliding hole is provided at the bottom of the shaft sleeve, a pair of L-shaped slots connected to the sliding hole are provided at the outer side of the shaft sleeve, and a pair of sliders are installed at the top end of the stirring rod, and the sliders slide in the L-shaped slots.

[0015] The beneficial effect of adopting the above further solution is that, by using the L-shaped slot and the slider, the user can freely remove the stirring rod, thereby achieving the purpose of facilitating the cleaning of the stirring rod.

[0016] Furthermore, the lifting mechanism includes a vertical rod, which is installed on the outside of the storage barrel. A slide groove is opened on one side of the vertical rod. The inside of the slide groove is connected with a threaded rod through a bearing. A second motor is installed on the top of the vertical rod. The output end of the second motor is transmission-connected to the threaded rod. A connecting block is installed on the outside of the barrel cover. The connecting block and the threaded rod are threadedly engaged and slide in the slide groove.

[0017] The beneficial effect of adopting the above further scheme is that the second motor drives the threaded rod to rotate, so that the connecting block moves in the slide groove to achieve the purpose of automatically lifting the box cover. Because the overall weight of the box cover equipped with the driving mechanism is heavy, using the second motor to lift the box cover can reduce the difficulty of lifting the box cover. After the box cover is lifted, the user can pour the material into the storage barrel.

[0018] Furthermore, the material storage mechanism includes an asphalt pump, which is installed on the outside of the material storage barrel through a frame, a first conduit is connected between the input end of the asphalt pump and the material storage barrel, and a second conduit is connected to the output end of the asphalt pump.

[0019] The beneficial effect of adopting the above further solution is that after the material is stirred, the asphalt pump is started to discharge the material through the first conduit and the second conduit.

[0020] The beneficial effect of the utility model is that the modified asphalt mixer obtained by the utility model through the above design can drive the turntable and the shaft sleeve to rotate simultaneously, so that the stirring rod can rotate and revolve at the same time, thereby fully stirring the materials in the mixing barrel to improve the stirring effect.
