A semi-automatic molecular sieve filling machine and a storage bin, the storage bin is arranged on one side of the filling machine, and the filling machine is fixedly connected with the storage bin through screws, and is connected with the storage bin through pipes; a placing box is arranged on one side of the filling machine, and the placing box is fixedly connected with the filling machine through screws, and the molecular sieve automatic filling machine can store the molecular sieve through the installed collection hopper The materials shaken off during filling are collected in the collection bucket, which will not let the materials fall all over the ground and cause waste. At the same time, the collected materials are introduced into the storage bin through the guide tube, and the scattered materials are directly put back into the storage bin, so as to avoid the rework problem of the operators and improve the work efficiency. Through the installation of the placement box, some common repair tools and some equipment can be placed Often need to replace the machine parts, convenient for repair workers to find parts and tools, improve the speed of maintenance. However, when the molecular sieve is transported to the aluminum alloy frame, the molecular sieve may be blocked at the outlet of the storage bin, and then the molecular sieve can not be discharged from the storage bin. At this time, the staff need to dredge the outlet. When dredging, the staff need to dismantle the storage bin or the hose connected with the storage bin to dredge, which will be a waste A lot of time, reduce the efficiency of the staff.
