DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] This embodiment provides a mixing material mixer, such as Figures 1 to 5As shown, it includes a stirring cylinder 1, and a stirring chamber is provided in the stirring cylinder 1. A material inlet is provided at the top of the stirring chamber, and a material outlet 4 is provided at the bottom of the stirring chamber. The bottom of the stirring chamber is inclined to form a slope. The material inlet corresponds to the bottom of the slope, and the material outlet corresponds to the top of the slope. The material inlet corresponds to the bottom of the bottom of the stirring chamber, and the material outlet 4 corresponds to the top of the bottom of the stirring chamber. A stirring shaft 5 is provided in the stirring chamber, and the stirring shaft 5 can transport the material from the bottom of the bottom of the stirring chamber to the top of the slope. The stirring chamber can be a rectangular cavity or a cavity of other shapes, but it must be ensured that the bottom of the cavity must be an inclined plane to form a slope. The cavity top of the stirring chamber can also be a slope parallel to the cavity bottom, or it can be non-slope, such as a parallel plane parallel to the horizontal plane or a plane of other structural shapes, without too much restriction.

[0028] Working principle:

[0029] The materials for mixing are filled into the mixing chamber from the material inlet 4. The mixing shaft 5 will mix the materials while transporting them from the bottom of the chamber to the top of the slope. During the forward movement of the materials, some of the materials will slide down under the action of gravity and then be transported to the top of the slope by the mixing shaft 5 again. The materials will increase the number of stirring times and the stirring time as they continue to fall back and move forward, thus improving the mixing quality of the materials (i.e., the uniformity of stirring). The materials reaching the top of the slope will be discharged from the material outlet 4. The mixer forms a slope by tilting the bottom of the mixing chamber so that the materials will continue to fall back and move forward under the action of gravity while moving forward, thereby increasing the stirring time. The purpose of uniform stirring of the materials can be achieved without increasing the length of the mixing cylinder 1, thereby avoiding affecting the layout and installation of the equipment. The mixer can be widely used for stirring various materials, especially foamed asphalt.

[0030] In one embodiment, if Figures 1 to 5 As shown, the material inlet includes a first inlet 2 and a second inlet 3, and the second inlet 3 is located between the first inlet 2 and the material outlet 4. The first inlet 2 is used to add the initial mixture, and the second inlet 3 is used to add additional materials, such as when used for foamed asphalt mixing, the first inlet 2 is used to add the initial mixture, and the second inlet 3 is used to add foamed asphalt.

[0031] In one embodiment, if Figures 1 to 5 As shown, it includes an inclination adjustment device, through which the slope of the slope, that is, the inclination angle of the bottom of the stirring chamber, can be adjusted.

[0032] In one embodiment, if Figures 1 to 5As shown, the mixing cylinder 1 includes a hinged end and a lifting end, the hinged end corresponds to the bottom of the slope (the bottom of the mixing chamber), and the lifting end corresponds to the top of the slope (the bottom of the mixing chamber). The inclination adjustment device includes an articulated bracket 6 and a driving mechanism, the hinged end of the mixing cylinder 1 is hinged on the articulated bracket 6, and the articulated axis of the articulated end and the articulated bracket 6 is horizontally arranged. The driving mechanism is used to drive the lifting end of the mixing cylinder 1 to rotate around the hinged end to change the inclination angle of the mixing cylinder 1, thereby changing the inclination angle of the bottom of the mixing chamber, that is, the slope of the slope (the angle with the horizontal plane).

[0033] In one embodiment, if Figures 1 to 5 As shown, the driving mechanism includes a hydraulic telescopic cylinder 7, the cylinder body of the hydraulic telescopic cylinder 7 is hinged to the ground or platform, and the piston rod of the hydraulic telescopic cylinder 7 is hinged to the lifting end of the mixing cylinder 1. The piston rod is extended and retracted, so that the lifting end of the mixing cylinder 1 can be driven to rise and fall. In addition to the hydraulic telescopic cylinder 7, the driving mechanism can also use other telescopic mechanisms or lifting mechanisms, the fixed end of the telescopic mechanism or lifting mechanism is hinged to the ground or platform, and the movable end of the telescopic mechanism or lifting mechanism is hinged to the lifting end, such as a screw nut mechanism, including a rotating sleeve, a screw, a nut and a rotating motor, the rotating sleeve is hinged to the ground or platform, the screw is rotatably connected to the rotating sleeve through a rotating bearing, the nut is threadedly connected to the screw, the nut is hinged to the lifting end, and the rotating motor drives the screw to rotate through a gear box, thereby driving the nut to move along the screw to realize the lifting of the lifting end, and another example is a scissor-type lifting platform, the base of the scissor-type lifting platform is hinged to the ground or platform, and the platform of the scissor-type lifting mechanism is hinged to the lifting end of the mixing cylinder 1.

[0034] In one embodiment, if Figures 1 to 5 As shown, it also includes a controller (not shown) and a weighing hopper. The weighing hopper is used to receive the material discharged from the material outlet 4. The weighing hopper and the inclination adjustment device are electrically connected to the controller. The controller can be a PLC controller.

[0035] Working principle:

[0036] When in use, first pre-adjust the inclination angle of the mixing cylinder 1 (that is, the slope of the slope formed by the bottom of the cavity) through the inclination adjustment device, and then the weighing hopper weighs the discharge of the material outlet 4. The weighing signal is transmitted to the controller, and the controller calculates the weight per unit time and compares it with the production volume per unit time pre-set in the controller. When it is greater than the set value, the inclination adjustment device increases the inclination angle of the mixing cylinder 1, increases the resistance, and reduces the material movement speed. When it is less than the set value, the inclination adjustment device decreases the inclination angle of the mixing cylinder 1, reduces the resistance, and increases the material movement speed, forming a closed-loop control process to achieve production volume control.

[0037] In one embodiment, if Figures 1 to 5As shown, the weighing hopper includes a hopper body 8 and a weighing sensor 9, and the hopper body 8 is suspended on the mixing cylinder 1 through the weighing sensor 9. Specifically, one end of the weighing sensor 9 is hinged on the mixing cylinder 1, and the other end of the weighing sensor 9 is hinged to the hopper body 8, so that the hopper body 8 is kept in a suspended state, and the hopper body 8 is located directly below the material outlet 4. The material discharged from the material outlet 4 falls into the hopper body 8, and the weighing sensor 9 can monitor the weight change of the hopper body 8.

[0038] In one embodiment, if Figures 1 to 5 As shown, a driving device is provided on the lifting end of the mixing cylinder 1, and the driving device is used to drive the mixing shaft 5 to rotate.

[0039] In one embodiment, if Figures 1 to 5 As shown, the driving device includes a driving motor 10, a gear box 11 and a coupling 13. The driving motor 10 is vertically mounted on the gear box 11, and the gear box 11 is mounted on the lifting end of the mixing tank 1. The input shaft of the gear box 11 is connected to the output shaft of the driving motor 10, and the output shaft of the gear box 11 is connected to one end of the mixing shaft 5 through the coupling 13. One end of the mixing shaft 5 is rotatably connected to the lifting end of the mixing tank 1 through a first bearing 14, and the other end of the mixing shaft 5 is rotatably connected to the hinged end of the mixing tank 1 through a second bearing 15.

[0040] In one embodiment, if Figures 1 to 5 As shown, two stirring shafts 5 are arranged in the stirring chamber of the mixing cylinder 1. The stirring shafts 5 include a rotating shaft and blades. The blades are arranged spirally on the rotating shaft. The blades of the two stirring shafts 5 are arranged in an interlaced manner, so that the blade of one stirring shaft 5 is located between two adjacent blades of the other stirring shaft 5, which can improve the stirring quality. The rotating shafts of the two stirring shafts 5 are parallel to each other, and a coaxial sleeve is provided on the stirring shaft 5, and the gear is fixedly connected to the stirring shaft 5. The gear is located between the coupling 13 and the first bearing 14, and the gears on the two stirring shafts 5 are meshed with each other, so that the rotating shafts of the two stirring shafts 5 can rotate synchronously and in opposite directions. The gear cover is provided with a gear cover 12, and the gear cover 12 covers all the gears on the two stirring shafts 5 at the same time. When two stirring shafts 5 are used, the stirring effect is better than that of a single stirring shaft 5 of the same length, so the rotating shaft length of the two stirring shafts 5 can be relatively shortened to maintain the same stirring effect or a higher stirring effect than that of a single one, thereby shortening the floor space of the overall mixer. For example, under the same stirring effect, the rotating shaft lengths of the two stirring shafts 5 are made smaller than the rotating shaft length of a single stirring shaft 5 .

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
