Body 14a
Of the four peripheral edges of the supply port F of the supply port main body 14a, the lid 14c projects from the front side edge (lower side edge) and the folds 14d project from the left and right side edges. However, the left and right side edges of the lid body 14c and the front side edge of the fold body 14d are integrally connected. Then, the supply port member 14 is assembled in a region where the main body 14a is framed by the stays 13b, 13c, 13d of the mounting frame 13 so that the side from which the lid 14c projects is the lower edge of the supply port, Then, by inserting the left and right arm portions and the straddling portion of the second stay 13c into the groove portions 14e formed on the back surfaces of the left and right side edges and the upper side edge, and adhering, the three edges excluding the lower end edge where the lid body 14c is extended. The parts are integrally fixed and made rigid.

Further, plate-shaped supporting portions 15h and 15i are formed on the cover lid 15, and these supporting portions 15h and 15i are fitted into the groove 14f formed on the outer surface of the peripheral portion of the lid body 14c and attached. The lid 14c is integrally fixed, whereby the portion of the lid 14c corresponding to the portion rigidified by the second stay 13c is made rigid. When the cover lid 15 is opened, the supply port F is greatly opened with the lid body 14c and the fold body 14d surrounding the front and left and right sides, and fertilizer can be supplied, but when the cover lid 15 is closed, A peripheral portion of the inner surface of the lid body 14c, which is made substantially flat (planar) and made rigid by the support portions 15h, 15i, is a side made rigid by the second stay 13c of the main body 14a. It is configured to come into contact with the edge and hermetically seal.

Further, with respect to the fold body 14d, in a state where the lid body 14c is naturally opened (that is, the supply port member 14 is in a natural state),
The supply port member 14 is in this natural state in a state in which it is curved so as to bulge slightly to the outside on the left and right sides, and as described above, the cover lid 15 is retained and held in the open position by the stopper 13h. Therefore, when the lid body 14c is closed by the closing operation of the cover lid 15, the fold body 14d inevitably bulges outward and bends, and the pleats of the supply port F are bent. When closed, the folds 14d fold inward and the lid 14c
It is taken into consideration that it is not sandwiched between and the peripheral portion of the supply port F. Moreover, on the upper edge of the fold body 14d, a collar piece 14g is formed inward on the body side half part,
When the supply port F is closed, the collar piece 14g covers the open upper part of the fold body 14d which is bulged and deformed to prevent the fertilizer from being scattered and lost.

Further, the tongue pieces 14h and 14i are provided on the upper opening edge of the supply port body 14a.
On the left and right sides of the opening, tongues 14j are respectively projected so as to face the inside of the opening.

It protrudes diagonally upward, and this tongue piece
14h, 14i, 14j are lids when the lid 14c is closed.
14c is pressed and deformed flexibly, and the supply port main body 14a and the lid 14
It is configured to elastically seal and seal the contact portion with c.

Further, at the upper opening edge of the supply port main body 14a, a shatterproof piece 14k is further provided so as to project in an inclined shape toward the front upper side,
The scattering prevention piece 14k is constructed so as to prevent the fertilizer overflowing from the supply port F from scattering toward the rear side of the bonnet 1b when the lid 14c is closed.

Furthermore, the prevention of active fertilizer scattering from the folds 14d is measured by the lower end of the pin 15g. That is pin 15g
The lower end portion of the lid 14c is in the vicinity of the outer side of the fold body 14d that is continuous with the lid body 14c when the lid body 14c is opened, and the lid body 14c is
Is disposed at a position projecting rearward (side in the closing direction) with respect to the closing surface (inner surface). When the cover lid 15 is closed, as described above, the fold body 14c bends while gradually bulging outward and deforming, but at this time, the pin 15g bulges and the fold body 14d on the side connected to the lid body 14c. The fold body 14d is brought into contact with the outer surface, whereby the fold body 14d is limited to the outward bulging deformation of the front side portion with respect to the portion with which the pin 15g is abutted, and the rearward side portion is outwardly outward. Swells and deforms. As a result, pin 15g
The fold body 14d that bulges and deforms by being pushed toward the portion of the fold body 14d that is connected to the supply port body 14a.
The gap between the front and rear sides of the fold is reduced to limit the inflow of fertilizer into the fold body 14d, and the space surrounded by the fold body 14d is set to be smaller than that bulged and deformed in the natural state. ing. Then, the pin 15g moves forward beyond the end edge of the supply port F at a position slightly before the lid 14c contacts the supply port main body 14a and closes the supply port F, and the pin 15g moves forward.
The folds 14d at the part where g abuts, the folds 14d on the side connected to the supply port body 14a are overlapped to close both the front and rear sides of the folds 14d, and thus just before the lid 14c is closed. It is configured to prevent the fertilizer from flowing into the swollen and folded fold body 14d when the movement of the fertilizer becomes maximum.

Further, in this structure, a support arm 1c having an upper end integrally fixed to the front lower end portion of the bonnet 1b is provided outside the foldable and deformable fold body 14d. The lower end of the support arm 1c is swingably supported on the body frame 1a side via a support shaft 1d, and the bonnet 1b is configured to swing open / close about the support shaft 1d as an axis. However, this support arm 1c interferes with the bulging and deforming fold body 14d so as to sandwich it with the pin 15g, and the fold body 14d bulges and deforms outward in the natural state. In addition to restricting the swelling, the bulging and deforming portion is left on the open side with respect to the pin 15g, and the space surrounded by the foldably deforming fold body 14d is made as small as possible. With
It is set to close the front and back sides at an early stage.
