[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a high-precision interval reduction scale, including: a mounting frame 1 and a hopper 4, a discharge pipe 3 is fixedly connected to the bottom of the hopper 4, a feeding barrel 2 is fixedly connected to the bottom of the discharge pipe 3, a discharge pipe 18 is fixedly connected to the outer surface of the feeding barrel 2, a guide pipe 8 is rotatably connected to the outer surface of the discharge pipe 18, a driven gear 19 is fixedly connected to the outer surface of the guide pipe 8, a mounting plate 21 is fixedly connected to the outer surface of the mounting plate 21, a first motor 7 is fixedly connected to the outer surface of the mounting plate 21, an output end of the first motor 7 is fixedly connected to a driving gear 19, an outer surface of the driving gear 20 is meshed with an outer surface of the driven gear 20, a second motor 10 is fixedly connected to the top center of the hopper 4, an output end of the second motor 10 movably penetrates the top of the hopper 4, and an output end of the second motor 10 is fixedly connected to a rotating shaft 12, a plurality of stirring rods 13 are equidistantly fixed on the outer surface of the rotating shaft 12, a first auger blade 14 is fixedly connected to the outer surface of the rotating shaft 12 near the bottom, the first auger blade 14 is located inside the discharge pipe 3, a third motor 17 is fixedly connected to the right end of the feeding barrel 2, an output end of the third motor 17 is fixedly and movably penetrated with the right end surface of the feeding barrel 2, a rotating rod 16 is fixedly connected to the output end of the third motor 17, a second auger blade 15 is fixedly connected to the outer surface of the rotating rod 16, a plurality of weighing sensors 5 are equidistantly fixedly connected to the top of the mounting frame 1, and the tops of the plurality of weighing sensors 5 are fixedly connected to the outer surface of the hopper 4.

[0024] The effect achieved by the entire embodiment 1 is that the material is put into the hopper 4, and then the hopper 4 is weighed through the cooperation of multiple weighing sensors 5, and then the detected signal is transmitted to the controller, and then the controller receives the signal and processes it, and then the speed of the third motor 17 is controlled by the frequency converter to achieve the effect of quantitative feeding. After the material is transported to the hopper 4, the second motor 10 is started to drive the rotating shaft 12 to rotate, so that the stirring rod 13 rotates in the hopper 4 to disperse and stir the material. At the same time, when the rotating shaft 12 rotates, it will cause the first auger blade 14 to rotate in the discharge pipe 3, avoiding the phenomenon that the material will be blocked in the discharge pipe 3, and then the material enters through the discharge pipe 3 In the feeding barrel 2, when the third motor 17 is started, the rotating rod 16 will be driven to rotate, and the second auger blade 15 will be driven to rotate in the feeding barrel 2, so that the material is transported and then enters the discharge pipe 18, and is discharged through the guide pipe 8. When the position of the guide pipe 8 needs to be adjusted, the third motor 17 is started to rotate its output end, thereby driving the driving gear 20 to rotate. Since the driving gear 20 is meshed with the driven gear 19, the driven gear 19 will be driven to rotate, so that the guide pipe 8 will rotate along the discharge pipe 18, and the direction of the guide pipe 8 can be adjusted, so that the discharge direction can be flexibly adjusted, which is convenient for adapting to different process requirements or spatial layouts and improving production efficiency.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the top hinge of the hopper 4 is connected to a protective cover 6, and the top of the hopper 4 near the second motor 10 is fixedly connected to an adsorption block 11, which is magnetically connected to the protective cover 6.

[0026] The effect achieved by the entire embodiment 2 is that when adding materials, the protective cover 6 can be pulled by the handle to rotate the protective cover 6 along the hinge to a certain angle, so that the protective cover 6 and the adsorption block 11 are adsorbed, and then the material can be added. After the addition is completed, the handle can be pulled to separate the protective cover 6 from the adsorption block 11, and the hopper 4 is sealed by the protective cover 6 to prevent the material from splashing out of the hopper 4 when the material is dispersed and stirred, causing environmental pollution.

[0027] Working principle: put the material into the hopper 4, and then weigh the hopper 4 through the cooperation of multiple weighing sensors 5, and then transmit the detected signal to the controller, and then the controller receives and processes the signal, and then controls the speed of the third motor 17 through the frequency converter to achieve the effect of quantitative feeding. After the material is transported to the hopper 4, the second motor 10 is started to drive the rotating shaft 12 to rotate, so that the stirring rod 13 rotates in the hopper 4 to disperse and stir the material. At the same time, when the rotating shaft 12 rotates, it will cause the first auger blade 14 to rotate in the discharge pipe 3, avoiding the phenomenon that the material will be blocked in the discharge pipe 3. During stirring, the hopper 4 is sealed by the protective cover 6 to avoid the material from being blocked. During dispersion and stirring, the material will splash out of the hopper 4, and then enter the feeding barrel 2 through the discharge pipe 3. When the third motor 17 is started, the rotating rod 16 will be driven to rotate, and the second auger blade 15 will be driven to rotate in the feeding barrel 2, so that the material will be transported and then enter the discharge pipe 18, and discharged through the guide pipe 8. When it is necessary to adjust the position of the guide pipe 8, the third motor 17 is started to rotate its output end, thereby driving the driving gear 20 to rotate. Since the driving gear 20 is meshed with the driven gear 19, the driven gear 19 will be driven to rotate, so that the guide pipe 8 will rotate along the discharge pipe 18, and the direction of the guide pipe 8 can be adjusted, so that the discharge direction can be flexibly adjusted.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
