DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] A top feed metering pump, such as Figure 1 and Figure 2 As shown, it includes an upper tube 1, a lower tube 2, a motor 3, a coupling 4, a bearing 5, an intermediate rotating shaft 6, an adsorption impeller 7, a discharge elbow 8 and a connecting mechanism 9. The lower tube 2 is provided at the lower side of the upper tube 1, and the motor 3 is provided at the upper side of the upper tube 1. The coupling 4 is connected to the output shaft of the motor 3, and the coupling 4 is connected to the bearing 5. The intermediate rotating shaft 6 is clamped on the bearing 5.

[0023] When using the utility model, first connect the upper tube 1 with the lower tube 2, connect the adsorption impeller 7 with the lower tube 2, then snap-fit ​​the intermediate shaft 6 with the bearing 5 on the coupling 4, then connect the motor 3 to the upper tube 1, make the intermediate shaft 6 snap-fit ​​with the adsorption impeller 7, when it is necessary to convey materials, pass the materials into the upper tube 1, start the motor 3, drive the intermediate shaft 6 to rotate, so that the adsorption impeller 7 rotates, adsorbs the materials downward, moves the materials to the lower tube 2, reduces the gaps between the materials, so as to achieve the purpose of quantitative, and then squeezes the materials out of the discharge elbow 8 for collection, when the upper tube 1 is connected to the lower tube 2, the plug-in upper joint 91 is snap-fitted with the plug-in lower joint 92, the plug-in upper joint 91 is snap-fitted with the plug-in lower joint 92, and the plug-in upper joint 91 is snap-fitted with the plug-in lower joint 92.
