[0002] In the process of sand processing, mixing is a key step. The effect of mixing directly affects the quality and performance of sand. In order to achieve efficient and uniform mixing, sand mixers came into being. Sand mixers are the main equipment for mixing sand in the casting process. They can evenly mix the components in the sand and effectively coat the binder on the surface of the sand particles.

[0003] Traditional sand mixers usually use multiple drive sources to drive different components, such as a rotor-type sand mixer described in the authorization announcement number CN219632521U, which is driven by two second motors and one first motor to achieve the effect of mixing the sand.

[0004] However, the use of multiple drive sources increases the cost and complexity of the equipment, and also increases the difficulty of maintenance and troubleshooting.

[0005] Meanwhile, in the prior art, two sets of rotor-type stirring rods are generally provided for stirring, and when the rotor-type stirring rods rotate, they can only stir the position where they are located, while the stirring effect at other positions will be poor.

[0006] To this end, we proposed a rotor sand mixer, which can mix sand through a driving source, which not only reduces costs and facilitates subsequent maintenance, but also can stir sand at various positions by setting up multiple stirring plates to improve the mixing effect. Utility Model Content

[0007] The utility model aims to provide a rotor type sand mixer, which can mix sand through a driving source, not only reducing the cost and facilitating subsequent maintenance, but also can stir the sand at various positions by setting a plurality of stirring plates, thereby improving the mixing effect.

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0026] like Figure 1-4 As shown, the technical solution adopted by the utility model is specifically as follows: a rotor type sand mixer, comprising a mixing cylinder 1 for carrying sand, a driving assembly is arranged at the bottom of the mixing cylinder 1, a first rotating sleeve 2 and a conical mixing plate 3 located inside the mixing cylinder 1 are arranged on the driving assembly, and two first fixed plates 4 are arranged outside the mixing cylinder 1, a first through hole is opened on the two first fixed plates 4, a first rotating rod 5 is rotatably arranged inside the first through hole, a second rotating sleeve 6 is arranged at the bottom of the first rotating rod 5, a transmission belt 7 is arranged on the second rotating sleeve 6 and the first rotating sleeve 2, and a first gear 8 is installed on the top of the first rotating rod 5;

[0027] A circular groove 9 is provided on the top of the mixing cylinder 1, a plurality of arc-shaped sliders 10 are provided inside the circular groove 9, a rotating ring 11 is provided on the top of the arc-shaped slider 10, a first meshing tooth 12 is provided inside the rotating ring 11, and a second meshing tooth 13 meshing with the first gear 8 is provided outside the rotating ring 11;

[0028] A plurality of second fixed blocks 14 are arranged in an array on the inner wall of the mixing cylinder 1, each of the second fixed blocks 14 is provided with a second through hole, a second rotating rod 15 is movably arranged inside the second through hole, a stirring plate 16 is arranged on the second rotating rod 15, and a second gear 17 is arranged on the top of the second rotating rod 15, and the second gear 17 is meshed with the first meshing tooth 12.

[0029] Its working principle is: first, the sand to be mixed is allowed to enter the mixing cylinder 1. When entering, the driving component is started, and the driving component drives the conical mixing plate 3 to provide centrifugal force, thereby improving the mixing effect. At the same time, the driving component drives the first rotating sleeve 2 to make the conveyor belt 7 drive the second rotating sleeve 6 to rotate, and the second rotating sleeve 6 drives the first rotating rod 5 to rotate on the fixed plate, and then drives the first gear 8 to rotate. The first gear 8 drives the second meshing tooth 13 to make the rotating ring 11 drive the arc-shaped slider 10 to rotate inside the circular slide groove. When the rotating ring 11 rotates, the first meshing tooth 12 drives the second gear 17 to make the second rotating rod 15 rotate, and the second rotating rod 15 drives the stirring plate 16 to mix the sand. The device can mix the sand through a driving source, which not only reduces the cost and facilitates subsequent maintenance, but also can stir the sand at each position by setting a plurality of stirring plates 16 to improve the mixing effect.

[0030] In order to facilitate the discharge of the mixed sand, a discharge pipe (not shown in the figure) is provided at the bottom of the mixing cylinder 1, and the mixed sand is discharged through the discharge pipe.

[0031] At the same time, the arc-shaped slider 10 matches the circular groove 9. Matching here means that the width of the arc-shaped slider 10 is the same as the width of the circular groove 9. The advantage of this setting is that the arc-shaped slider 10 can slide smoothly inside the circular groove 9 without getting stuck.

[0032] like Figure 4 As shown, the driving assembly includes a rotating shaft 18 arranged at the bottom of the mixing cylinder 1, the top of the rotating shaft 18 is connected to the conical mixing plate 3, a motor 19 is installed at the bottom of the rotating shaft 18, and a first rotating sleeve 2 is sleeved on the rotating shaft 18.

[0033] The motor 19 drives the rotating shaft 18 to rotate the first rotating sleeve 2 and the conical mixing plate 3, thereby performing work.

[0034] Among them, a bracket is arranged on the motor 19, the bracket is connected to the mixing cylinder 1, and the motor 19 is fixed by the bracket.

[0035] There are multiple groups of stirring plates 16, and one side of one group of stirring plates 16 is provided with a scraper (not shown in the figure), through which the sand adhering to the inner wall of the mixing cylinder 1 can be scraped off.

[0036] A support frame 20 is provided at the bottom of the mixing cylinder 1, and the support frame 20 supports the entire device.

[0037] The working principle of the utility model is as follows: first, the sand to be mixed is allowed to enter the mixing cylinder 1. When entering, the driving component is started, and the driving component drives the conical mixing plate 3 to provide centrifugal force, thereby improving the mixing effect. At the same time, the driving component drives the first rotating sleeve 2 to make the conveyor belt 7 drive the second rotating sleeve 6 to rotate, and the second rotating sleeve 6 drives the first rotating rod 5 to rotate on the fixed plate, and then drives the first gear 8 to rotate. The first gear 8 drives the second meshing tooth 13 to make the rotating ring 11 drive the arc-shaped slider 10 to rotate inside the circular slide groove. When the rotating ring 11 rotates, the first meshing tooth 12 drives the second gear 17 to make the second rotating rod 15 rotate, and the second rotating rod 15 drives the stirring plate 16 to mix the sand. The device can mix the sand through a driving source, which not only reduces the cost and facilitates subsequent maintenance, but also can stir the sand at various positions by setting a plurality of stirring plates 16 to improve the mixing effect.

[0038] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
