[0034] refer to Figure 1 , Figure 2 and Figure 3 A limiting mechanism 12 is fixedly connected to both the front and rear sides of the surface of the rotating rod 10. The limiting mechanism 12 includes a cam rod 13, a cam rod 2 14 at the bottom of the cam rod 13, a connecting plate 15 fixedly connected to the bottom of the cam rod 2 14, a spring 16 fixedly connected to the bottom of the connecting plate 15, a connecting plate 2 17 fixedly connected to the bottom of the spring 16, and the bottom of the connecting plate 2 17 fixedly connected to the weighing chamber assembly 1.

[0035] As a technical optimization of this utility model, the position of the rotating rod 10 can be restricted by the setting of the limiting mechanism 12, so as to avoid the phenomenon of rotation when rotation is not required, and to ensure the stability of the cover plate assembly 4.

[0036] refer to Figure 3 Both sides of the inner side of the connecting plate 15 are fixedly connected with reinforcing strips 18, which are used in conjunction with the connecting plate 15.

[0037] As a technical optimization of this utility model, by setting the reinforcing strip 18, the connecting plate 15 can operate synchronously, thereby increasing the stability of the movement of the connecting plate 15.

[0038] refer to Figure 3 A limiting block 19 is fitted on the front side of the surface of the rotating rod 10, and the bottom of the limiting block 19 is fixedly connected to the weighing chamber assembly 1.

[0039] As a technical optimization of this utility model, the setting of the limiting block 19 enables the rotating rod 10 to rotate more stably, and at the same time, it limits the rotation trajectory of the rotating rod 10.

[0040] refer to Figure 3 An inclined block 20 is fixedly connected to the right side of the limiting block 19, and the bottom of the inclined block 20 is fixedly connected to the weighing chamber assembly 1.

[0044] The working principle and usage process of this utility model are as follows: First, when the user needs to open the cover assembly 4, the motor 7 is started. The output end of the motor 7 drives the pulley 8 to rotate. The pulley 8 drives the pulley 11 to rotate through the connecting belt 9. The pulley 11 drives the rotating rod 10 to rotate. The rotating rod 10 drives the cover assembly 4 to flip, so that the cover assembly 4 can be opened automatically, achieving the effect of automatically opening the top cover. Then, while the rotating rod 10 is rotating, the cam rod 13 will also rotate. The cam rod 13 pushes the cam rod 14 downward. When the cam rod 13 and the cam rod 14 are misaligned, the cam rod 14 will abut against the rotating rod 10, achieving the effect of positioning the rotating rod 10.

[0045] In summary, this concrete powder metering device changes the traditional manual opening method by using a rotary rod 10 to automatically flip the cover assembly 4, which facilitates material feeding and increases the overall metering efficiency.
