Is mounted rotatably so that the front end side moves up and down according to the unevenness of the topsoil surface of the field, and the up and down movement of the front part of the center float 70 is detected by the up and down movement detection mechanism 72 during the planting operation. By switching the hydraulic valve that controls the lifting hydraulic cylinder 46 according to the result, the seedling placement part 4 is moved up and down, so that the planting depth of the seedling is always kept constant.

The fertilizer applicator 5 is provided with a main body comprising a fertilizer hopper 80, which is a common fertilizer storage section for each row, and a fertilizer feeding section 81,... One end of fertilizing hoses 82,... Is connected to the lower part of the fertilizing hoses 82,.
71 are connected to fertilizer guides 83,. A blower 85 driven by a motor 84
An air chamber 86 serving as an air supply unit for supplying air from the fertilizer application hoses 82,. The fertilizer stored in the fertilizer hopper 80 is fed out by a constant amount by the fertilizer feeding sections 81,..., And the fertilizer is fed through the fertilizer hoses 82,. Are transported and dropped into fertilizing grooves formed near the side portions of the seedling attachment strips by the groove forming members 87 provided on the front side of the fertilizing guides 83. Hereinafter, the structure of the main part of the fertilizer applicator will be described (see FIGS. 5 to 7).

An openable and closable lid 80a is attached to a fertilizer input port provided on the upper part of the fertilizer hopper 80.
The lower part of the fertilizer hopper 80 is funnel-shaped for each strip,
The internal fertilizer is supplied to the fertilizer feeding sections 81 by free fall.

Each of the fertilizer feeding sections 81 is provided with a feeding roll 91 for feeding the fertilizer downward by a predetermined amount inside a case 90 communicating vertically. This feeding roll 91
Is composed of a groove roll 91a having a plurality of fertilizer feeding grooves 92,... Formed in an outer peripheral portion thereof, and a claw roll 91b having claw-shaped projections slidably engaged with grooves of the groove roll. Roll support cylinder 93 configured in combination and provided in the left-right direction
Are rotatably supported on the outer periphery. One end of the feeding shaft 95 driven by the fertilizer driving mechanism is freely rotatably fitted in the roll support cylinder 93, and the rotation of the feeding shaft 95 is transmitted to the feeding roll 91 via the fertilizing clutch body 96 and the relay body 97. Is done. By rotating the feeding roll 91 in the direction of the arrow in FIG. 5, the fertilizer in the fertilizer hopper 80 is fed into the fertilizer feeding groove 9.
2,... Are held and extended downward.

The fertilizer drive mechanism transmits the rotation of the fertilizer drive shaft 100 projecting upward from the planting clutch case 28 to the relay shaft 102 via the bevel gear case 101,
Further, a common feeding shaft 9 is used for every two adjacent members from the relay shaft.
Belt transmissions 103, 103, 10 to 5, 95, 95
3 to drive the respective feeding rolls 91,.

The claw roll 91b includes a roll support cylinder 93.
Is provided so as to move in the axial direction integrally with the opening adjustment gear 105 screwed into the screw portion 93a of the second member. The opening adjustment gear 105 has a pinion 10 attached to the opening adjustment shaft 106.
7 are engaged. When the opening adjustment shaft 106 is rotated using the opening adjustment handle 108, the opening adjustment gear 105 is rotated.

The leveling brush 1 is provided on the inspection door 113 so as to be in sliding contact with the outer peripheral surface of the feeding roll 91 moving downward so that the fertilizer feeding groove 92 receives the fertilizer in a cut-off state.
15 is detachably attached. Case 9
The rear wall surface 90a and the feeding roll 91 are in contact with each other without any gap, so that the fertilizer does not fall from behind the feeding roll 91. If fertilizer is contained in the fertilizer feeding groove 92 in which a part of the rear side wall surface 90a is hung, it becomes an obstacle that the nail roll 91b moves to the side where the feeding amount decreases when the fertilizer feeding amount is adjusted. Therefore, on the upper side of the rear side wall surface 90a, a fertilizer stopping brush 1 for preventing fertilizer from entering the fertilizer feeding groove 92 in a state where the rear side wall surface partially overlaps.
16 are provided.

Below the leveling brush 115, there is provided a powder removing case 118 in which a net 118a finer than the diameter of the fertilizer is detachably attached to the upper part. The fertilizer that has dropped from the fertilizer feeding groove 92 is once received by the net 118a, and is rolled over the net 118a and supplied downward. Fertilizer fragments and flour are sifted through net 118a,
It collects in the powder removal case 118. Therefore, clogging of the fertilizer due to the fertilizer powder adhering to the lower portion of the fertilizer storage unit 81 is prevented. The dust removing case 118 can be taken in and out of the inspection door 113. Further, at the time of inspection of the fertilizer storage unit 81, the net 118a of the powder removing case 118 may be removed so that the fertilizer fed by the feeding roll 91 is collected in the powder removing case 118.

At the lower ends of the fertilizer feeding sections 81,..., Connecting pipes 120,... Are connected to each other, and fertilizer hoses 82,. . The front ends of the connection pipes 120 are inserted and connected to the rear surface of an air chamber 86 having a cylindrical cross section provided in the left-right direction. The air outlet of the blower 85 is connected to the left end of the air chamber 86 via a joint pipe 121, and the air from the blower 85 is blown into the connection pipes 120 of each strip through the air chamber 86. The fertilizer fed from the fertilizer feeding sections 81,... Is transferred together with air to the fertilizer hoses 82,. The air chamber 86 is provided with the link base frame 4
2 and is supported by the fertilizer hopper 80 and the fertilizer feeding section 81.

A fertilizer take-out pipe 123 whose tip end extends obliquely downward is provided on the back surface above the feed roll 91 in the fertilizer feed section case 90. This fertilizer removal pipe 1
A fertilizer recovery shutter 125 that is opened and closed by an opening and closing lever 124 is attached to 23. The tips of the fertilizer removal pipes 123,...
6 is connected. Further, the left end of the fertilizer collection pipe 126 is connected to the blower 85 through the joint pipe 121, and the right end is a collection port, to which an openable and closable collection lid 127 is attached. Further, the right end of the fertilizer collection pipe 126 and the inside of the fertilizer hopper 80 communicate with each other via an air hose 128.

The connecting pipe 121 is forked, and one connection port is connected to the air chamber 86, and the other connection port is connected to the fertilizer collection pipe 126. The branch portion is provided with a ventilation switching shutter 130 that switches between a state in which air from the blower 85 is blown into the air chamber 86 and a state in which the air is blown into the fertilizer collection pipe 126. The ventilation switching shutter 130 is switched by a ventilation switching lever 131.

When the residual fertilizer in the fertilizer hopper 80 is collected at the end of the operation, the air of the blower 85 is supplied to the fertilizer collection pipe 1.
The air supply switching shutter 130 is switched so as to blow into the inside 26, and the fertilizer recovery shutter 125 is opened in that state. Then, the fertilizer of the fertilizer hopper 80 is taken out to the fertilizer collection pipe 126 through the fertilizer take-out pipe 123, and is transported by air to the inside of the fertilizer collection pipe 126 to the collection port side to be collected from the collection port. Part of the air blown into the fertilizer collection pipe 126 is sent into the fertilizer hopper 80 through the air hose 128. For this reason, the pressure in the fertilizer hopper 80 increases, and the fertilizer is discharged from the fertilizer hopper 80 smoothly.
