The utility model relates to the technical field of fertilization, in particular to a detachable blanking bin with a filtering device for a
fertilizer adding machine, which is characterized by comprising an upper bin body and a lower bin body, the upper bin body is detachably inserted in the lower bin body, a bolt I is detachably connected in the upper bin body and the lower bin body, a nut I is screwed on the bolt I, and a nut II is screwed on the nut II. The bottom of the lower bin body fixedly communicates with a discharging
pipe. The detachable upper bin body and the detachable lower bin body are arranged, so that transportation is facilitated, and the risk of
extrusion deformation in the transportation process is reduced; by arranging the filtering
assembly,
fertilizer blocks, plastic bags, leaves, soil blocks and other impurities are prevented from blocking the discharging
pipe, and the fertilization efficiency and effect are prevented from being affected; and by arranging the control
assembly, the actual size of the discharging opening of the discharging
pipe can be adjusted, and then the discharging speed is adjusted.
