The invention discloses a bin pump constant-temperature control device, and relates to the technical field of bin pump temperature control. The problem that a bin pump controls the constant temperature of a raw material in the use process is solved. By means of the scheme, the bin pump constant-temperature control device comprises a shell. Supports are welded to the outer walls of the two sides ofthe shell. A dual-shaft motor is fixedly connected with the top of the shell. The bottom output end of the dual-shaft motor is provided with a first rotating shaft. Six pairs of stirring blades are arranged on the first rotating shaft at equal intervals. The top output end of the dual-shaft motor is provided with a first driving bevel gear. A first driven bevel gear is arranged on the right sideof the first driving bevel gear. The first driving bevel gear is in meshing transmission with the first driven bevel gear. The right side of the first driven bevel gear is fixedly connected with a screw through a bolt. Through the combination of various structures, the heating and cooling efficiency of the device is improved, working time is shortened, cost is saved, the cooling and heating of thedevice are definitely separated, and the error probability of the device is reduced.
