The two sets of drive structures are completely independent to ensure the synchronous rotation of the two layers of rotors and the accurate measurement and mixing of materials. However, since this method consumes double the power resources, it will cause energy waste and increase the cost of use. In addition, since the powder contains some particles, when the particles rub against the internal mechanism of the rotor scale, the particles will cause wear on the internal structure of the equipment. In severe cases, it will also cause jamming or friction during mechanical operation, thereby increasing the wear rate of the equipment.

Example 1
[0034] Reference Figure 1-5, which is the first embodiment of the utility model, provides a powder double-layer rotor scale, which includes a base 1, a shell 2 installed on the surface of the base 1, a discharge port 3 installed on one side of the shell 2, a first rotary scale 4 and a second rotary scale 5 installed inside the shell 2, the first rotary scale 4 is located on the top of the second rotary scale 5, and a chute for convenient material discharge is opened on the surface of the first rotary scale 4, a driving member 6 and a crushing member 7 are installed on the top of the shell 2, and the crushing member 7 is located on one side of the driving member 6;
[0035] The driving member 6 includes a rotating rod 61 installed on the surface of the shell 2. The bottom of the rotating rod 61 passes through the shell 2 and extends to the inside of the second rotating scale 5 and is fixedly connected thereto. A first bevel tooth 62 is fixedly connected to the surface of the rotating rod 61. A sleeve rod 63 is movably sleeved on the surface of the rotating rod 61. One end of the sleeve rod 63 extends to the inside of the shell 2 and to the inside of the first rotating scale 4 and is fixedly connected thereto. A second bevel tooth 64 is fixedly connected to the surface of the sleeve rod 63. The first bevel tooth 62 is located at the top of the second bevel tooth 64. The sleeve rod 63 is connected to the bearing of the rotating rod 61 to prevent the sleeve rod 63 from moving up and down on the surface of the rotating rod 61. The first rotating scale 4 and the second rotating scale 5 are connected to the rotating rod 61 through the sleeve rod 63, and the first rotating scale 4 and the second rotating scale 5 are not in contact with each other. The bevel tooth refers to a bevel gear.
[0036] The surfaces of the rotating rod 61 and the sleeve rod 63 are movably connected to the limit frame 65, the outer side of the limit frame 65 is installed with a motor 67, the inner side of the limit frame 65 is installed with a third bevel gear 66, the output end of the motor 67 extends to the inside of the limit frame 65 and is fixedly connected to the third bevel gear 66, and the rotating rod 61 and the sleeve rod 63 are connected through the bearing of the limit frame 65.
[0037] The limit frame 65 is in the shape of a rounded rectangle, and a bracket 68 is fixedly connected to the bottom of the limit frame 65. The bottom of the bracket 68 is fixedly connected to the top of the shell 2, which can limit the limit frame 65 to prevent it from rotating, while ensuring the stability of the rotating rod 61 and the sleeve rod 63.
[0038] The third bevel gear 66 is located on one side of the first bevel gear 62 and the second bevel gear 64. The third bevel gear 66, the first bevel gear 62 and the second bevel gear 64 are meshed with each other. The rotation of the third bevel gear 66 can drive the first bevel gear 62 and the second bevel gear 64 to rotate synchronously in opposite directions, so as to drive the rotating rod 61 and the second rotating scale 5, and the sleeve rod 63 and the first rotating scale 4 to reverse synchronously, so as to achieve the purpose of one set of driving structures driving two sets of rotating scales to reverse synchronously, and at the same time, it can save resources and reduce costs.
[0039] When the powder falls onto the surface of the first rotary scale 4 after being ground by the crushing element 7, the motor 67 is started to drive the third bevel gear 66 to rotate, and drive the first bevel gear 62 and the second bevel gear 64 to rotate synchronously in opposite directions, driving the rotating rod 61 and the second rotary scale 5, and the sleeve rod 63 and the first rotary scale 4 to reverse synchronously, thereby achieving the purpose of one set of driving structures driving two sets of rotary scales to reverse synchronously, while saving resources and reducing costs. Example 2
[0040] Reference Figure 1-7 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:
[0041] The crushing component 7 includes a feed barrel 71 installed on the top of the shell 2. A feed port 72 and a motor 73 are provided on the top of the feed barrel 71. The feed port 72 is located on one side of the motor 73. A crushing block 74 is movably sleeved inside the feed barrel 71. The output end of the motor 73 extends to the inside of the feed barrel 71 and is fixedly connected to the crushing block 74.
[0042] A groove 75 is provided on the inner side of the feed barrel 71, and a circular array of arc blocks 76 are fixedly connected to the surface of the crushing block 74. The arc blocks 76 are located inside the groove 75 and are movably connected. A cavity 77 is provided between the two groups of arc blocks 76. The arc blocks 76 are located inside the groove 75 to limit the crushing block 74 and prevent it from sliding down from the inside of the feed barrel 71. At the same time, there are two groups of grooves 75, and two rows of arc blocks 76. The cavities 77 provided between the two rows of arc blocks 76 are arranged in an alternating manner, so that the powder or particles can slide down along the inside of the cavity 77 to the inside of the first rotary scale 4, and at the same time, the particles can also be ground to prevent them from causing wear to the internal structure of the rotary scale.
[0043] The top arc surface 79 of the crushing block 74 is set, and the outer surface of the top of the crushing block 74 is provided with a circular array of guide grooves 78, and the guide grooves 78 are located on the top of the arc block 76. The arc surface 79 can facilitate the movement of powder and particles toward the outer surface of the crushing block 74. At the same time, the guide grooves 78 can move the powder and particles toward the groove 75, the arc block 76 and the cavity 77, which is convenient for the grinding of the particles and accelerates the powder to enter the first rotary scale 4.
[0044] During use, the powder is transported to the inside of the feed port 72 through the external setting, and the motor 73 is started to drive the crushing block 74 to rotate along the inside of the feed barrel 71, and the two rows of arc blocks 76 on the outer surface of the crushing block 74 rotate along the groove 75 on the inner side of the feed barrel 71. When the powder enters the inside of the feed barrel 71, the powder will be dispersed to the outer surface of the top of the crushing block 74 due to the rotation of the crushing block 74 and the arc surface 79 on its top, and fall into the inside of the groove 75 through the guide groove 78. The particles will be ground during the rotation of the arc block 76. The ground particles are dispersed and fall to the surface of the first rotary scale 4 through the cavity 77. In this way, the particles can be ground and the problem of particles causing wear to the internal structure of the equipment can be prevented.
[0045] The remaining structures are the same as those of Example 1.
[0046] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
