The invention discloses a bucket-elevator-type transferable coal mine paste filling device which comprises a main material storage device, a bucket elevator, an auxiliary material storage device, a water additive box, a control room unit, a first steel supporting-leg box, a second steel supporting-leg box, a first floor located above the first supporting-leg box and the second supporting-leg box, a first supporting part, a second supporting part and a second floor located above the first supporting part and the second supporting part, wherein the first supporting part and the second supporting part are located on the first floor. The bucket-elevator-type transferable coal mine paste filling device further comprises a measuring device, a stirring device, a filling pump and an electric control system, the measuring device, the stirring device and the filling pump are sequentially connected through a connecting pipe, and the filling pump is further provided with a paste conveying pipeline in a connecting mode. Compared with a traditional steel frame structure, the bucket-elevator-type transferable coal mine paste filling device has the advantages that the contact area of the box structure and the ground is larger, the box structure can be arranged on surface of the ground stably, during actual use, concrete foundations do not need to be constructed, disassembly, assembly and transferring are convenient, and the construction amount and the construction difficulty of projects are effectively reduced.
