And floats the fertilizer with a fertilizer hose 62,. , 56, 56 are guided to the fertilizer guides 63 attached to both the left and right sides, and in the fertilizer grooves formed near the side portions of the seedling-growing strips by the grooved bodies 64,. It comes to drop into. The air generated by the blower 67 driven by the motor 66 is blown into the fertilizer hose 62,... Via the air chamber 68 that is long in the left-right direction, and the fertilizer in the fertilizer hose 62,. It is like that.
[0014]
Hereafter, the structure of each part of the fertilizer applicator main-body part shown in FIGS. 3-12 is demonstrated.
The fertilizer hopper 60 is shared by each strip, and a lid 60a that can be opened and closed is attached to the top. The lower part of the fertilizer hopper 60 is branched into a number of fertilizer strips and has a funnel shape, and the lower part is connected to the upper ends of the feeding parts 61. The fertilizer hopper 60 is attached to two left and right rotating arms 71 supported by a fertilization frame 70 that is long in the left-right direction. The feeding portion 61 is rotated rearward with the lower end of the rotating arm 71 as a fulcrum. , ... can be separated from ... The rotating arm 71 is disposed between the first and second feeding portions from the outside. In a normal position where the lower part of the fertilizer hopper 60 is connected to the upper ends of the fertilizer feeding parts 61,..., The fertilizer hopper 60 is fixed by a locking tool 72.
[0015]
The feeding unit 61 includes two feeding rolls 73A and 73B that feed the fertilizer in the fertilizer hopper 60 downward. These feeding rolls 73A, 73B are rotating bodies having groove-shaped recesses 74,... Formed on the outer peripheral portion thereof, and are provided on a corner shaft portion 75a (a square shaft in the illustrated example) of a common feeding shaft 75 provided in the left-right direction. They are fitted so as to rotate together. As the feed rolls 73A and 73B rotate in the direction of the arrow in FIG. 7, the fertilizer dropped and supplied from the fertilizer hopper 60 is accommodated in the recess 74 and fed downward. The fertilizer fed out by both the feeding rolls 73A and 73B is discharged from the discharge port 61a at the lower end.
[0016]
The number of concave portions of the feeding rolls 73A and 73B in the illustrated example is six, and the phases of the concave portions are different from each other. For this reason, the concave portions of the feeding rolls 73A and 73B alternately feed the fertilizer, and the amount of the fertilizer discharged from the discharge port 61a is equalized in terms of time. By removing any one of the feeding rolls from the feeding shaft 75 and changing the phase appropriately, the phases of the recesses of both the feeding rolls 73A and 73B can be made equal. This makes it possible to apply fertilizer to the field in the form of dots.
[0017]
In addition, a brush 76 slidably in contact with the outer peripheral surface of the feeding roll 73 on the side (front side) where the concave portion 74 moves downward is detachably provided inside the feeding portion 61. The fertilizer is housed in the recesses 74 of the feeding rolls 73A and 73B by the brush 76 in a state of being scraped, and the amount of fertilizer fed by the feeding rolls 73A and 73B is kept constant.

Further, on the upper side of the brush 76, feeding stop shutters 77A and 77B that protrude above the feeding rolls 73A and 73B and prevent the fertilizer from dropping and fed from the fertilizer hopper 60 to the feeding portion 61 are provided. The feeding stop shutters 77A and 77B are slidably supported by the slide support portion 79 of the feeding portion case 78, and are slid by grasping a handle 77a formed at the front end portion outside the case. Since the feeding stop shutter 77 is provided so as to cover the attachment portion of the brush 76 from above, no fertilizer is applied to the attachment portion of the brush 76. If the width of the two feeding stop shutters 77A and 77B is made wider than the width of the brush 76, the fertilizer will not be applied to the attachment portion of the brush 76 more reliably.
[0019]
As shown in FIG. 16, when a rubber material 160 slidably in contact with the inner surface of the case 78 is embedded in the outer peripheral portion of the feeding roll 73, the durability of the feeding roll 73 is improved, and the maintenance is facilitated accordingly. Is obtained.
[0020]
A connection pipe 80 that communicates in the front-rear direction is connected to the discharge port 61 a of the feeding portion 61. A fertilization hose 62 is connected to the rear end of the connection pipe 80. Since the lower end portion of the fertilizer frame 70 is engaged with the outer peripheral spiral groove of the fertilizer hose 62, the fertilizer hose 62 is difficult to come off from the connection pipe 80. On the other hand, the front end portion of each connection pipe 80 is inserted and connected to the back surface portion of the air chamber 68. The left end portion of the air chamber 68 is connected to a blower 67 via an air switching pipe 81, and air from the blower is blown into the fertilizer hose 62 from the connection pipe 80 via the air chamber 68.
[0021]
The air chamber 68 is configured by alternately connecting a rubber pipe 68a to which a connecting pipe 80 is attached and a resin pipe 68b at an intermediate portion. With this configuration, the air chamber 68 can be easily disassembled and assembled, so that the maintenance with the feeding portion 61 removed as a whole is easy. If the length of the rubber tube 68a is made longer than the distance between the pair of feeding portions, the rubber tube 68a can be easily removed from the resin tube 68b.
[0022]
Further, a fertilizer discharge port 83 for taking out the fertilizer in the fertilizer hopper is formed on the back surface portion of the feeding portion case 78. The fertilizer discharge port 83 is provided with a discharge shutter 84 that can be opened and closed with the upper end side as a fulcrum. The fertilizer discharge port 83 of each feeding part is connected to a fertilizer collecting pipe 85 that is provided behind the feeding part 61 and that is long in the left-right direction. The left end portion of the fertilizer collection pipe 85 is connected to the blower 67 through the air switching pipe 81. The air switching pipe 81 is a bifurcated pipe, and an air chamber 68 is connected to one side and a fertilizer collection pipe 85 is connected to the other side. The air switching pipe 81 is provided with an air switching shutter 86, which can be switched between a state in which air blown from the blower 67 is supplied to the air chamber side and a state in which the air is supplied to the fertilizer recovery pipe side. The right end portion of the fertilizer collection pipe 85 is a fertilizer collection port 87.
[0023]
FIG. 9 is a view showing an opening / closing mechanism of each of the shutters 84,. A fertilizer recovery lever 90 is rotatably provided in the vicinity of the fertilizer recovery port 87. A shutter opening / closing transmission shaft 91 that is long in the left-right direction and is disposed on the front side of the feeding portion 61 is provided coaxially with the rotation fulcrum shaft 90a of the fertilizer recovery lever 90. A fan-shaped plate 92 is attached to the shutter opening / closing transmission shaft 91, and a pin 90 b fixed to the fertilizer collecting lever 90 is loosely fitted in an arc-shaped elongated hole 92 a formed in the fan-shaped plate 92. An opening / closing gear 93 is attached to the shutter opening / closing transmission shaft 91 for each feeding portion, and the gear meshes with a semicircular gear 94 attached to the rotation shaft 84 a of the discharge shutter 84. In addition, since the stopper part 94a whose diameter is larger than the tooth | gear of the said gear is formed in the edge part of the semicircular gear 94, both gears do not disengage. Further, one end of an air switching wire 95 is connected to the fertilizer recovery lever 90. The other end of the air switching wire 95 is connected to an arm 96 attached to the rotation shaft 86 a of the air switching shutter 86 via a tension spring 97.
[0024]
When the fertilizer recovery lever 90 is rotated, the air switching wire 95 is pulled to switch the air switching shutter 86, and the air drawn from the blower 67 is supplied to the fertilizer recovery pipe 85. As long as the amount of rotation of the fertilizer recovery lever 90 is small, the pin 90b only moves in the elongated hole 92a, so the shutter opening / closing transmission shaft 91 does not rotate. However, when the fertilizer recovery lever 90 is rotated more than a certain amount, the pin 90b is engaged with the fan-shaped plate 92, and the shutter opening / closing transmission shaft 91 is rotated. Thereby, the discharge shutters 84,... Open, and the fertilizer in the fertilizer hopper 60 is discharged to the fertilizer collection pipe 85. That is, the air switching shutter 86 and the discharge shutter 84,... Can be operated with only one lever operation. In addition, inevitably, air is first supplied to the fertilizer recovery pipe 85, and thereafter the fertilizer is discharged to the fertilizer recovery pipe 85. For this reason, the fertilizer is smoothly conveyed in the fertilizer recovery pipe 85, and the fertilizer clogging in the fertilizer recovery pipe 85 does not occur. Further, since the fertilizer recovery lever 90 is provided in the vicinity of the fertilizer recovery port 87, a fertilizer recovery container and the like can be easily secured below the fertilizer recovery port 87, and further work can be performed while checking the state of fertilizer recovery. Convenient.
[0025]
The fertilizer collecting lever 90 is rotated along the lever guide 98. Guide holes 98a and 98b are formed in the lever guide 98, and an engaging portion (not shown) of the fertilizer recovery lever 90 is engaged with the guide holes 98a and 98b by utilizing the bending of the fertilizer recovery lever 90. Thus, the fertilizer recovery lever 90 can be fixed at a position P1 where only the air switching shutter 86 is switched, and a position P2 where both the air switching shutter 86 and the discharge shutters 84,.
[0026]
The feeding portion case 78 is divided into a lower fixing portion 78a and an upper separation portion 78b, with a dividing surface FF inclined downward in a side view. The feeding rolls 73A and 73B and the discharge shutter 84 (fertilizer discharge port 83) are provided in the fixed portion 78a. On the other hand, the brush 76 and the feeding stop shutter 77 are provided in the separation portion 78b. Since the upper opening and the discharge port 61a to which the fertilizer hopper 60 is connected are not divided, the airtightness of both is kept good.
[0027]
When the fertilizer hopper 60 is rotated most rearward, the fertilizer hopper is positioned outside the area projected in the direction in which the separation portion 78b is detached in a side view. For this reason, the detachment part 78b can be detachable without difficulty. Further, the extension destination of the dividing surface FF is located below the upper end of the air chamber 68, and the air chamber 68 is located outside the area projected in the direction in which the separation portion 78b is detached in a side view. For this reason, it is easy to perform maintenance of the feeding rolls 73A and 73B from the traveling vehicle body 2 with the detached portion 78b removed.
[0028]
Next, the fertilization transmission mechanism 27 will be described.

By bringing the driven roller 126 closer to the driving roller 125, the seedling feeding belt 51b is loosened and the seedling feeding stop state is entered. When the fertilizer rod clutches 106L, 106C, 106R1, and 106R2 are turned off by operating the rod clutch levers 110L, 110C, and 110R, the corresponding two seedling feeding belts 51b are linked to the seedling feeding stop state.
[0035]
The planting clutch case 25 has an internal structure shown in FIG. Rotational power is transmitted from the input shaft 130 to the planting clutch shaft 131 via the inter-stock transmission gears 132,. Each of the drive side stock shift gears 132,... Is independently engaged with the input shaft 130, and only one of them is integrated with the input shaft 130 via a shifter key 134. On the other hand, the driven inter-gear transmission gears 133,... Are integrally formed with each other and are connected to the planting clutch shaft 131 through a planting clutch 135 operated by a clutch pin 135a so as to be able to be turned on and off. When the shifter key 134 is slid with the shift rod 134a, the effective combination of the inter-stock transmission gears 132 and 133 is changed. Thereby, the transmission ratio from the input shaft 130 to the planting clutch shaft 131 can be adjusted in four stages.
[0036]
A fertilizer clutch shaft 137 is provided coaxially with the input shaft 130. The planted clutch shaft 131 is transmitted to the fertilizer clutch shaft 137 by a pair of eccentric gears 138 and 139. A fertilizer clutch shaft 137 is provided with a fertilizer clutch 140 that is operated by a clutch pin 140 a, and is transmitted from the fertilizer clutch 140 to a fertilizer output shaft 143 through a pair of bevel gears 141 and 142.
