Is formed with a U-shaped operation frame 119b that is open upward, and a left side surface of the operation frame 119b is open to the outside of the machine body.

In such a configuration, the operating body 66
Is pulled out, the residual fertilizer take-out port 65 is opened, the residual fertilizer is dropped into the residual fertilizer guide member 118 from the intermediate member 117 through the intake 118a, and falls onto the residual fertilizer receiver 119a. Thereafter, when the operation frame 119b is gripped and reciprocated in the lateral direction of the machine body, the residual fertilizer on the residual fertilizer receiver 119a rolls on the residual fertilizer receiver 119a or on the previously deposited residual fertilizer accumulation layer. It moves to the exit side end while sliding, and falls into the residual fertilizer container 100 arranged below as it is.

Thus, there is no need to separately provide a belt or a driving device thereof, so that the production cost can be reduced and the maintainability can be improved, and the residual fertilizer discharge mechanism 90 can be sufficiently provided even in a small space. can do.

The labor of repeating only the discharge work can be saved, and the residual fertilizer can be automatically collected in the residual fertilizer container just by opening the residual fertilizer outlet, greatly reducing the burden on the workers, Work efficiency can also be significantly improved.

The bottom surface of the residual fertilizer guide member according to the first aspect is inclined downward to the outlet side, so that the dropped residual fertilizer is efficiently conveyed to the outlet side and clogging of the residual fertilizer occurs during the conveyance. Can also be prevented.

Since the residual fertilizer guide member according to the third aspect is divided into a plurality of parts, the inclination of the conveying surface toward the outlet side can be made larger than in the case where the residual fertilizer guide member is one. The transfer efficiency can be further improved.
