Detailed Description

In order to make the technical solutions of the present invention clearer and clearer for those skilled in the art, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings, but the embodiments of the present invention are not limited thereto.

A dry powder storing and metering device comprises a hopper 1, a weighing module 2, a lifting module 3 and a scattering and spiral conveying module 4;

the hopper 1 is funnel-shaped, is internally provided with a partition board, is divided into two chambers and is used for placing different raw materials;

weighing modules 2 are arranged at four corners of the lower part of the outer side of the hopper 1 and used for weighing the total weight; a hopper cover 5 is arranged at the upper part of the hopper 1. The weighing module 2 with higher metering precision is adopted to accurately meter the reduction amount of the powder in the hopper 1 in real time so as to determine whether to adjust the filling amount;

the lifting module 3 comprises a lifting motor 32 and four lifters 33, the four lifters 33 are arranged at four corners of the hopper 1 and are driven by a transmission mechanism 34 to keep synchronous lifting, and the lifters 33 are also provided with limit pins 31 which are fixed at a certain height when lifted to a certain height; when the device stops working and needs to be transferred and transported, the lifting module 3 jacks up the hopper 1 and leaves the weighing module 2, so that the module can be protected from being damaged in the transportation process.

The lower parts of the two chambers of the hopper 1 are provided with scattering and spiral conveying modules 4 for scattering and conveying materials.

The scattering and spiral conveying module 4 comprises a scattering shaft 44, a scattering motor 43, a spiral conveying shaft 42 and a spiral conveying motor 41; the scattering shaft 44 is driven by the scattering motor 43 and is arranged at the upper part of the spiral conveying shaft 42; the spiral conveying shaft 42 is driven by a spiral conveying motor, and a feed opening 45 is arranged at the first end; and a shell is arranged outside the scattering shaft 44 and the spiral conveying shaft 42 and is connected with a discharge hole of the hopper 1.
