[0024] The effect achieved by the entire embodiment 1 is that, first, when the machine is placed, the meter 8 and the infrared sensor 10 are both arranged on the outer wall of the metering bin 3. Through the action of the infrared sensor 10 and the meter 8, the infrared sensor 10 can accurately determine whether the material in the metering bin 3 has reached a predetermined height or capacity, thereby ensuring the accuracy of mixing. In cooperation with the meter 8, it avoids the operator from frequently opening the metering bin 3 to obtain metering data, reduces the risk of contact with internal materials, and reduces the possibility of safety accidents. Secondly, the height of the stirring mechanism can be adjusted by the lifting rod 11. According to the nature of the material and the mixing requirements, the height of the stirring mechanism can be flexibly adjusted, and the stirring intensity and method can be changed, thereby optimizing the stirring effect.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, the four parts of the connecting plate 12 are fixedly installed with a top cover 13, a hole 2 14 is opened on the top of the top cover 13, and the inner surface wall of the hole 2 14 is fixedly connected with a feed pipe 15, a hole 3 16 is opened on the top of the top cover 13, and a rotating rod 17 is movably inserted into the inner surface wall of the hole 3 16, and a group of connecting rings 18 are fixedly sleeved on the outer surface wall of the rotating rod 17, and a stirring rod 19 is fixedly installed on the outer surface wall of a group of connecting rings 18, and a connecting ring 2 20 is fixedly sleeved on the outer surface wall of the rotating rod 17, and two connecting frames 21 are fixedly installed on the outer surface wall of the connecting ring 20, and stirring rods 22 are fixedly installed on the outer surfaces of the two connecting frames 21, and a driving motor 23 is arranged on the top of the rotating rod 17, a weight sensor 24 is arranged on the inner surface wall of the bottom plate 1, and a controller 25 is arranged on the top of the bottom plate 1.

[0026] The effect achieved by the entire embodiment 2 is that when the device is used normally, the driving motor 23 is first connected to the rotating rod 17, the rotating rod 17 is connected to the stirring rod 19 through the connecting ring 18, and the rotating rod 17 is connected to the connecting ring 20, and the connecting ring 20 is connected to the stirring rod 22 through the connecting frame 21.

[0028] Working principle: First, when the device is in normal use, the bottom of the base plate 1 is fixedly connected to the top of the four legs 2. The four legs 2 can separate the main body of the device from the ground by a certain distance, which helps to reduce the erosion of the equipment by ground moisture and prolong the service life of the equipment. Secondly, a hole 14 is opened on the top of the top cover 13, and the inner wall of the hole 14 is fixedly connected with a feed pipe 15. The material is put into the metering bin 3 by connecting the feed pipe 15. Secondly, a square hole 7 is opened on the outer wall of the metering bin 3, and a metering meter 8 is set on the inner wall of the square hole 7. Table 8 Operators do not need to stop the equipment or perform additional operations to obtain metering data, saving time and energy, thereby improving production efficiency. At the same time, the outer wall of the metering bin 3 is provided with a square hole 9, the inner wall of the square hole 9 is provided with an infrared sensor 10, and the inner wall of the bottom plate 1 is provided with a weight sensor 24. The infrared sensor 10 can provide high-precision detection results and accurately sense the position, quantity or state changes of the material. At the same time, the weight data recorded by the weight sensor 24 can be used as an important basis for the production process, which is convenient for quality control. The problem is traced and analyzed. Secondly, a lifting rod 11 is fixedly installed on the top of the bottom plate 1. A connecting plate 12 is fixedly installed on the top of the lifting rod 11. The connecting plate 12 is fixedly connected to the top cover 13. The height of the top cover 13 can be adjusted by the operation of the lifting rod 11. At the same time, the driving motor 23 is located above the top cover 13, and the driving motor 23 is connected to the rotating rod 17. The rotating rod 17 is fixedly connected to the connecting ring 18 and the connecting ring 20. Secondly, the connecting ring 18 is connected to the stirring rod 19, and the connecting ring 20 is connected to the stirring rod through the connecting frame 21. The two stirring rods 22 are connected, so the lifting rod 11 can eventually adjust the height of the stirring mechanism and raise the stirring mechanism to a suitable position, which is convenient for operators to inspect, repair and clean the stirring parts and the inner wall of the container, reducing the difficulty and risk of operation. At the same time, the driving motor 23 drives the rotating rod 17 to rotate, and finally drives the stirring rod 19 and the stirring rod 22 to rotate to mix and stir the fracturing dry powder, which can more reasonably distribute the stirring energy and avoid excessive or insufficient local energy concentration, thereby reducing energy consumption and improving energy utilization efficiency.
