Description

Technical Field

[0001] The utility model relates to an asphalt concrete production stirring device, belonging to the technical field of asphalt concrete production. Background Art

[0002] Asphalt concrete, commonly known as asphalt concrete, is a mixture of artificially selected mineral materials with a certain graded composition, such as crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., and a certain proportion of road asphalt materials, mixed under strictly controlled conditions. During the production and processing of asphalt concrete, various mineral materials must be mixed and stirred through special mixing equipment.

[0003] There are still some problems in the use of an existing asphalt concrete production mixing device. A heating device is generally installed on the outside of the existing mixing device to prevent the asphalt from solidifying inside the equipment. However, the position of the existing heating device remains unchanged, so that the asphalt inside the equipment cannot be heated evenly. In addition, the contact area between the existing mixing device and the asphalt is relatively small, resulting in uneven mixing. If a larger mixing blade is used, the resistance between the mixing blade and the asphalt concrete will increase, thereby affecting the normal production and processing of the equipment. Utility Model Content

[0004] The purpose of the utility model is to provide an asphalt concrete production mixing device. The utility model has a simple structure and is easy to use. It can evenly heat the interior of the equipment when mixing the asphalt concrete inside the equipment body, while increasing the contact area between the stirring blade and the asphalt concrete while reducing the resistance encountered, so as to solve the problems raised in the above-mentioned background technology.

[0010] Furthermore, the heater is electrically connected to the controller, the air outlet holes are evenly distributed in the inner wall of the heating coil, and the interior of the heating coil is hollow. The end of the telescopic air pipe away from the heater is fixedly connected to the interior of the heating coil.

The heating mechanism 6 includes a motor 61, a rotating shaft 62 is fixedly connected to the output end of the motor 61, a belt 63 is connected to the outer side of the rotating shaft 62, and a rotating rod 64 is connected to the end of the belt 63 away from the rotating shaft 62. A screw rod 65 is fixedly connected to the bottom of the rod 64, a U-shaped frame 66 is fixedly connected to the outside of the equipment body 1, a slide groove 67 is provided on the inner side of the U-shaped frame 66, a ferrule 68 is threadedly connected to the outside of the screw rod 65, a limiting rod 69 is fixedly connected to the outside of the ferrule 68, a moving rod 610 is fixedly connected to the outside of the ferrule 68, a heating coil 611 is fixedly connected to the outside of the moving rod 610, an air outlet 612 is provided in the inner wall of the heating coil 611, a heater 613 is fixedly connected to the outside of the U-shaped frame 66, a controller 614 is fixedly connected to the outside of the heater 613, and a telescopic air pipe 615 is fixedly connected to the outside of the heater 613.

[0025] Specifically, Figure 1 As shown, the screw rod 65 is rotatably connected to the inside of the U-shaped frame 66, the end of the limiting rod 69 away from the ring 68 is slidably connected to the inside of the slide groove 67, the heating coil 611 is slidably connected to the outside of the device body 1, the heater 613 is electrically connected to the controller 614, the air outlet holes 612 are evenly distributed in the inner wall of the heating coil 611, and the inside of the heating coil 611 is hollowed out, the end of the telescopic air pipe 615 away from the heater 613 is fixedly connected to the inside of the heating coil 611, and the screw rod 65 can be rotated inside the U-shaped frame 66 by the use of the rotating shaft 62 and the belt 63. Since the end of the limiting rod 69 away from the ring 68 is slidably connected to the inside of the slide groove 67, it can limit the ring 68 outside the screw rod 65. When the screw rod 65 rotates, it can drive the heating coil 611 to move outside the device body 1.

[0026] In this embodiment: asphalt concrete is placed into the interior of the equipment body 1 through the feed trough 3 on the outside of the equipment body 1.

[0028] Specifically, Figure 1-4 As shown, the rotating rod 71 is rotatably connected to the inside of the equipment body 1, and the bottom of the rotating rod 71 is rotatably connected to the inner bottom wall of the equipment body 1, the fixed rod 72 and the stirring blade 73 are symmetrically distributed on the outside of the rotating rod 71, and the leakage holes 74 are evenly distributed inside the stirring blade 73.

[0029] In this embodiment: by setting up the equipment body 1, by starting the motor 61, the motor 61 drives the rotating shaft 62 to rotate, and the rotating shaft 62 drives the rotating rod 71 to rotate inside the equipment body 1. Since the fixed rod 72 is fixedly connected to the outside of the rotating rod 71, when the rotating rod 71 rotates, the fixed rod 72 can drive the stirring blade 73 to rotate.
