Is fixed to the frame (136). In addition, the air bleeding pipe (139) having an openable / closable lid (138) that is closed and moved by its own weight is connected to the hose joint pipe (137).
The hose joint pipes (137) for six sections are formed in the same shape and structure, and the six sections are interchangeable to improve the assembly workability. . Further, as shown in FIG. 21, an air release pipe (140) is provided in the middle of the transfer hose (40) at a high position near the hose joint (69), and the pipe (4) is provided.
A vibration plate (142) is provided in the air vent (141) of (0), and a predetermined amount or more of air is discharged from the air vent (141) when fertilizer is clogged at the feed hose end side of the transfer hose (40). Thus, an alarm sound is generated by the vibration of the diaphragm (142), and the worker is alerted of a fertilizer conveyance failure. As is clear from the above embodiments, the present invention provides an air tank (42) for supplying fertilizer conveying air, a fertilizer feeding case (38) for sending out fertilizer, and a planting section (15).
Feeding fertilizer Kyusuru conveying hose (40) and, together with the linking by a hose joint (69), the outlet of the fertilizer feeding cases (38) (67) and the hose joint (69)
In fertilizer inlet (70) planting machine Ru provided a flexible fitting cap for detachably connecting (71) a Hosujo

3), and close the feeding case (38).
The bottom cover (66) is detachably fixed via the closing lever (65).
And an outlet (67) is formed in the bottom lid (66).
Secure the fitting cap (71) to the outlet (67) of the lid (66).
And attach the cap (71) to the hose joint.
(69) It is detachably fitted to the entrance (70),
The fitting cap (71) easily improves the confidentiality of the fitting portion.
Fertilizer leakage from the fitting part of the fitting cap (71).
