DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0029] Below, refer to Figure 1A stirring mechanism of a coarse aggregate reactive powder concrete stirring device according to an embodiment of the present invention will be described in detail.

[0030] like Figure 1 As shown, according to an embodiment of the present invention, a stirring mechanism for a coarse aggregate reactive powder concrete stirring device is provided. The stirring device includes a stirring box for stirring concrete, and the stirring mechanism includes a ring gear 103, a rotating assembly, a self-rotating gear 104, a rotating rod 106, a driving device 101, a first stirring assembly, and a second stirring assembly. The ring gear 103 is fixed to the inner wall of the stirring box of the stirring device and its horizontal plane is perpendicular to the central axis of the stirring box. The gear teeth of the ring gear 103 are located on its inner wall; the rotating assembly is rotatably arranged on the central axis of the ring gear 103; the self-rotating gear 104 is rotatable along the inner side of the ring gear 103 and meshes with the ring gear 103; one end of the rotating rod 106 is fixedly connected to the rotating assembly, and the other end is connected to the self-rotating gear 104, and the self-rotating gear 104 can rotate on the rotating rod 106; the driving device 101 is fixed to the stirring device, and the output shaft of the driving device 101 is connected to one end of the rotating assembly for driving the rotating assembly to rotate; the first stirring assembly is connected to the other end of the rotating assembly, and the second stirring assembly is connected to the other end of the rotating rod 106.

[0031] It should be noted that the mixing device is provided with a mixing box specifically for containing concrete for mixing concrete, and the mixing of the concrete is completed in the mixing box. The mixing mechanism of the embodiment of the utility model is used in the mixing box to achieve the mixing of concrete in the mixing box.

[0032] Here, ring gear 103 has inner teeth. The size of ring gear 103 can be selected based on the size of the mixing tank. The parameters of autorotating gear 104 are coordinated with ring gear 103. The rotating assembly can be fixed to ring gear 103 or to the mixing tank via other supporting structures, so that it is located on the central axis of the mixing tank and can rotate about its central axis. The first and second mixing assemblies are used to stir the concrete in the mixing tank to achieve sufficient mixing of the concrete. The first mixing assembly can also be used to scrape the concrete against the inner wall of the mixing tank.

[0033] Thus, the driving device 101 drives the rotating assembly to rotate, which in turn drives the rotating gear 104 to rotate within the ring gear 103 via the rotating rod 106, thereby driving the first mixing assembly to achieve orbital revolution and the second mixing assembly to achieve self-rotation around the central axis of the ring gear 103. Furthermore, through the ingenious structural design, the mixing mechanism achieves both planetary self-rotation and orbital revolution. With a single motor, the two mixing assemblies can mix concrete in multiple directions and angles, making it easy to control. Furthermore, the two mixing assemblies can not only fully mix the concrete, but also scrape away concrete adhering to the inner wall of the mixing chamber, thus preventing it from sticking to the wall.

[0034] In one embodiment, the rotating assembly includes a rotating shaft 102 and a rotating gear 112. The rotating shaft 102 is rotatably mounted on the ring gear 103 and is located on the central axis of the ring gear 103. The rotating gear 112 is a bevel gear and is fixed to one end of the rotating shaft 102. The output shaft of the driving device 101 is connected to the rotating gear 112. The first stirring assembly is connected to the other end of the rotating shaft 102. One end of the rotating rod 106 is fixedly connected to the rotating shaft 102. Here, the rotating shaft 102 can be fixed to the ring gear 103 by other support structures, or it can be fixed in the mixing box by other support structures, so that the rotating shaft 102 is located on the central axis of the mixing box and the rotating shaft 102 can be rotated on other supports. Therefore, the rotation of the rotating gear 112 can be driven by the driving device 101 to drive the rotation of the rotating shaft 102, thereby driving the rotation of the rotating rod 106. This structure is convenient for installation and layout and saves space.

[0035] In one embodiment, an output gear 113 is mounted on the output shaft of the drive device 101. The output gear 113 is a helical gear that mates with the rotating gear 112. The output shaft is perpendicular to the central axis, and the output gear 113 meshes with the rotating gear 112. In this embodiment, the drive device 101 is a motor. This facilitates the layout and power transmission of the drive device 101, and the helical gears change the power transmission path, thus saving space.

[0036] In one embodiment, a gear bracket 111 is further included. The gear bracket 111 secures the ring gear 103 to the inner wall of the mixing tank, positioning the ring gear 103 at the center of the mixing tank. The gear bracket 111 comprises a plurality of support rods, one end of which is secured to the inner wall of the mixing tank and the other end to the ring gear 103. The plurality of support rods are evenly distributed in a circular pattern within the mixing tank. This facilitates the installation and securing of the ring gear 103 within the mixing tank.

[0037] In one embodiment, a self-rotating rod 105 is further included, and the self-rotating gear 104 is fixed to the self-rotating rod 105. Two rotating rods 106 are included, and the other ends of the two rotating rods 106 are respectively connected to the two ends of the self-rotating rod 105, so that the self-rotating gear 104 is clamped between the two rotating rods 106. In this way, the self-rotating rod 105 can be pushed by the rotating rod 106 to cause the self-rotating gear 104 to rotate in the ring gear 103. This structure is more stable and reliable, which is conducive to improving the stability of the entire stirring mechanism.

[0038] In one embodiment, the first stirring assembly includes a revolving frame 107 and a revolving blade 108. The revolving frame 107 is in the shape of an elongated strip, one end of which is fixed to the other end of the rotating assembly (i.e., one end of the revolving frame 107 is fixed to the other end of the rotating shaft 102). The revolving blade 108 is in the shape of an L-shaped plate, one of the longer ends of the revolving blade 108 is fixed to the other end of the revolving frame 107. The second stirring assembly includes a plurality of self-rotating frames 109 and self-rotating blades 110. Each self-rotating frame 109 is in the shape of a V-shape, and each self-rotating blade 110 is in the shape of a square plate. One end of each self-rotating frame 109 is connected to a self-rotating blade 110. The other end of half of the self-rotating frames 109 is integrally fixed to the other end of the rotating rod 106 (i.e., fixed to the lower end of the self-rotating rod 105). The other end of each self-rotating frame 109 in the other half of the self-rotating frames 109 is fixed to the upper portion of each self-rotating frame 109 in the other half of the self-rotating frames 109. The V-shaped angle of each rotating frame 109 is not less than 90 degrees. Thus, the multiple mixing blades can fully mix the concrete, and the revolving blades 108 can scrape the concrete on the inner wall of the mixing box to prevent it from sticking to the wall.

[0039] Thus, the stirring mechanism of the coarse aggregate reactive powder concrete mixing device of the present invention solves the technical problems of insufficient stirring and difficult control in the existing related art. Beneficial effects are achieved: Through a clever structural design, the stirring mechanism achieves both planetary rotation and revolution, enabling two stirring assemblies to stir concrete in multiple directions and angles using a single motor, making it easy to control. Furthermore, the two stirring assemblies not only fully stir the concrete but also scrape away any concrete adhering to the inner wall of the mixing chamber, preventing it from sticking to the wall.
