TECHNICAL FIELD

[0001] The utility model relates to a kind of viscous substance mixing devices, in particular to a kind of road repair material mixing device. BACKGROUND

[0002] With use or local ground excavation, various ground damage problems such as cracks, pits, settlement, notches and the like occur on hardened ground such as urban ground and highway, and the road administration department will periodically repair the hardened ground that appears damaged. Common ground repair materials include cement concrete, asphalt and asphalt concrete. Cement concrete has high strength after solidification, but the solidification time is relatively long, so it is generally used as a foundation material. Asphalt is mainly used to fill ground cracks, and asphalt concrete has the characteristics of easy repair and construction, short solidification time, and is particularly suitable for repairing surface pavement.

[0003] Asphalt concrete is formed by mixing asphalt and aggregate. Asphalt has the characteristics of high-temperature melting and low-temperature solidification, so it needs to be maintained at 70°C or higher during the mixing process of asphalt concrete. In addition, asphalt concrete has a high consistency, and conventional mixing equipment cannot be used for the production of asphalt concrete. Therefore, a mixing device specifically used for mixing asphalt concrete needs to be developed. SUMMARY

[0006] The weighed aggregate is put into the mixing barrel through the aggregate feeding port, and the hot-melt asphalt is discharged from the asphalt feeding pipe, and the discharge amount is related to the weight of the aggregate, the stirring mechanism of the utility model adopts the planetary gear mechanism, the motor drives the vertical main shaft to rotate through the reduction box, the sun gear on the main shaft drives all the planetary gears to rotate synchronously, and the planetary gears are also engaged with the gear ring, so that the planetary gears can rotate around the sun gear while rotating on their own axes, the planet carrier is used for restraining and positioning the planetary gears, and the stirring rod is eccentrically fixed on the planetary gears, so that the stirring rod rotates around the planetary gears, and the movement track of the stirring rod relative to the sun gear is a spiral curve, so that the movement track of a single stirring rod can cover most of the internal space of the mixing barrel, and the utility model with multiple stirring rods has good mixing effect. The size of the stirring rod should not be too large, because the consistency of the asphalt is large, the larger the size of the stirring rod, the greater the resistance during stirring, and the speed of the planetary gears rotating on their own axes is relatively slow, so that the bending and torsional force of the stirring rod is reduced. The heating assembly can continuously keep the mixing barrel warm, and the temperature in the mixing barrel is maintained at 70-80 DEG C.

[0007] Further, the bottom of the planetary gear is coaxially fixedly connected with a flange, the flange comprises a short pipe, an inner flange arranged on the upper end of the short pipe and an outer flange arranged on the lower end of the short pipe, the inner flange is bolted with the planetary gear, and the stirring rod is fixedly penetrated on the outer flange; the stirring mechanism further comprises a rubber separation piece, the rubber separation piece is simultaneously sleeved on all the short pipes, the edge of the rubber separation piece is close to or abuts against the inner wall of the mixing barrel, and the aggregate feeding port and the asphalt feeding pipe are arranged below the rubber separation piece. The flange is used for fixedly connecting the planetary gear and the stirring rod, and facilitates replacement and installation of the stirring rod. Meanwhile, the flange also plays a role of installing and positioning the rubber separation piece, and the rubber separation piece also rotates simultaneously during operation of the utility model, and simultaneously plays a role of isolating the asphalt concrete and the planetary gear assembly.

[0008] Further, the stirring rod is provided with stirring blades. The stirring blades are narrow in width and are distributed along the axial direction of the stirring rod, so that the stirring efficiency can be effectively improved.

[0009] Further, the discharging mechanism comprises a discharging port arranged at the bottom of the mixing barrel, a turnover rod rotatably connected to the bottom of the mixing barrel, a plug arranged on the turnover rod and an executor for controlling turnover of the turnover rod, and the plug is provided with a rubber sleeve. The executor can be a pneumatic cylinder or a motor. The utility model controls the action of the executor through a program, so that the turnover rod can automatically drive the plug to separate from or seal the discharging port. The position of the discharging port is also eccentrically arranged, and generally corresponds to the movement track of the planetary gear in the up-down direction. In this way, during discharging, the continuous stirring action of the stirring rod can push the asphalt concrete to flow to the discharging port, which is helpful to empty the asphalt concrete.

[0010] Furthermore, the aggregate inlet is covered with a rubber curtain. The rubber curtain does not affect the aggregate feeding and also has a certain sealing effect to prevent heat from escaping from the aggregate inlet.

[0011] Therefore, this utility model has the following characteristics compared with the prior art: 1. The mixing mechanism of this utility model adopts a planetary gear mechanism, and the mixing rod is eccentrically fixed on the planetary gear, so that the movement trajectory of the mixing rod relative to the sun gear is a spiral curve. Therefore, the movement trajectory of a single mixing rod can cover most of the internal space of the mixing barrel. This utility model with multiple mixing rods has a better mixing effect. The heating component can continuously keep the mixing barrel warm, maintaining its internal temperature between 70 and 80°C, and keeping the asphalt with good fluidity; 2. This utility model controls the actuator through a program, so that the flipping rod can automatically drive the plug to separate or seal from the discharge port. The position of the discharge port corresponds vertically to the running trajectory of the planetary gear. The continuous mixing action of the mixing rod will push the asphalt concrete to flow towards the discharge port, which helps to empty the asphalt concrete. Attached Figure Description
