Next, the fertilization transmission mechanism 27 will be described. The fertilizing power transmission mechanism 27 is arrange | positioned from the left side, and is arrange | positioned between the fertilizer dispensing part 61 of Article 4 and Article 5.

The crank arm 131 protruding from the rear surface of the implant clutch case 25 is rotated output, and the reciprocating motion in the vertical direction of the driving side swing rod 132 extending in the vertical direction connected to the crank arm 131 is upward. Is rotated to the counter arm 133. In addition, the counter arm 133 has a square shape when viewed from the side, and is connected to the driving side swinging rod 132 and the driven side swinging rod 134 described later. Then, the reciprocating motion of the driven-side swinging rod 134 in the forward and backward directions due to the reciprocating swing of the counter arm 133 is transmitted to the feeding input arm 135 behind the counter arm 133, and this feeding input arm 135 The reciprocating operation in the front-rear direction of is transmitted to the one-way clutch 136L on the left side. On the other hand, two one-way clutches 136L and 136R are provided on the left and right sides, and are configured to rotate around the same one-way clutch shaft 137 in the left and right directions, and the outer ring portions 138L and 138R and the above-mentioned. A roller clutch provided with a plurality of transmission rollers 139 between the one-way clutch shaft 137 to transmit rotation of the outer ring portions 138L and 138R to the one-way clutch shaft 137. Therefore, in the one-way clutch 136L on the left side, the outer ring portion 138L is provided integrally with the feeding input arm 135 and becomes one direction in the reciprocating operation in the front-rear direction of the feeding input arm 135. The rotation of the outer ring portion 138L is transmitted to the one-way clutch shaft 137. On the other hand, the left and right one-way clutches 136L and 136R are transmitted to the one-way clutch shaft 137 by rotation in the same direction as the respective outer ring portions 138L and 138R.

Above the outer ring portion 138L of the one-way clutch 136L on the left side, a first arm 140 integral with the outer ring portion 138L is provided, and the first arm 140 and the second second in front of the outer ring portion 138L. The arm 141 is connected by the first link 142. The second arm 141 is configured to rotate integrally with the relay shaft 143 in the left and right directions, and from the relay shaft 143 to connect the first link 142 below the relay shaft 143. Extends downward; On the right side of the second arm 141, a third arm 144, which is integrally rotated with the relay shaft 143, is extended upward from the relay shaft 143. The third arm 144 is a second arm. Rotate integrally with 141. The second link 145 is connected to a position above the relay shaft 143 of the third arm 144, and the fourth arm 146 is connected to the other end side of the second link 145. The fourth arm 146 is provided integrally with the outer ring portion 138R above the outer ring portion 138R of the one-way clutch 136R on the right side. Accordingly, the first arm 140 reciprocates in the front-rear direction by the reciprocating rotation of the outer ring portion 138L of the one-way clutch 136L on the left side, and the second arm 141 through the first link 142. And the second arm 141 rotates back and forth in the same direction in synchronism with the first arm 140. Since the third arm 144 extends up and down (upwardly) from the second arm 141 with respect to the relay axis 143, the second arm 141 is located at the connection position with the second link 145. In synchronism with the reciprocating rotation of the reciprocating rotation, the reciprocating oscillation of the reciprocating motion in the front-rear direction at the connection position of the first link 142 of the second arm 141 is performed. Then, the reciprocating motion of the third arm 144 is transmitted to the fourth arm 146 through the second link 145, and the fourth arm 146 is synchronized with the third arm 144 in the forward and backward directions. Since the outer ring portion 138R of the one-way clutch 136R on the right side rotates in the reciprocating direction, the outer ring portion 138R rotates in the opposite direction in synchronization with the reciprocating rotation of the outer ring portion 138L of the one-way clutch 136L on the left side. Accordingly, the first arm 140 to the fourth arm 146, the first link 142, and the second link 145 constitute a reverse transfer mechanism.

Therefore, since the outer ring portions 138L and 138R of the left and right one-way clutches 136L and 136R are rotated to the opposite sides by the reverse transfer mechanism, the left and right one-way directions in the reciprocating operation of the feeding input arm 135. The one-way clutch shaft 137 of either of the clutches 136L and 136R is rotated in the same one direction (forward rotation direction), so that the one-way clutch shaft 137 can be driven continuously at all times.

Between the left and right one-way clutches 136L and 136R, a drive gear 147 which is integrally rotated by the one-way clutch shaft 137 and the key 147a is provided, and the drive gear shaft 147 is described later. Meshes with a driven gear 148 which rotates integrally with 105; Therefore, the continuous rotation of the one-way clutch shaft 137 is transmitted to the feeding drive shaft 105. On the other hand, the number of teeth of the drive gear 147 is larger than the number of teeth of the driven gear 148, which is about twice the number of teeth of the driven gear 148.

When the one-way clutches 136L and 136R are being repaired or repaired, the E-type stop wheel 204 is removed to move the left and right hexagon shaft portions 105b to the left and right, respectively. By disconnecting the connection with 105a), the one-way clutches 136L and 136R can be separated for each one-way clutch shaft portion 105a, and the one-way clutches 136L and 136R are provided on the feeding drive shaft 105. On the other hand, the one-way clutches 136L and 136R can be easily separated to facilitate maintenance.

17 and 18 show another reverse transmission mechanism, in which the first gear 206 and the second gear 207 integrally rotate with the outer ring portion 138L of the one-way clutch 136L on the left side. And the third gear 208 is engaged with the outer ring portion 138R of the one-way clutch 136R on the right side and the fourth gear 209 integral with the outer ring portion 209. 138R). Since this reverse transmission mechanism is comprised by the gears 206, 207, 208, and 209, compared with using the arm or the link mentioned above, transmission can be performed reliably and with high precision. The third gear 208 is provided by the feeding amount switching lever 211 so as to be movable left and right in the rotational axis direction, and can release engagement with the second gear 207. Therefore, the dispensing amount switching lever 211 enables the reverse transmission mechanism to be in a non-electrical state. The dispensing transfer mechanism can be made non-electrical by one-touch clutch 136L on the left side, and one-touch with one-two-feed amount. Can be easily changed. Conventionally, since the link of the reverse transmission mechanism has been removed and the reverse transmission mechanism is in a non-electric state, the operation of disconnecting the link has been troublesome. On the other hand, on the right side of the third gear 208, a fixing clutch 210 constituted by a drive clutch click 210a fixed to the gear and a driven clutch click 210b fixed to the machine main body side is provided. When the reverse transmission mechanism is in the non-electrical state, the third gear 208 which always engages with the fourth gear 209 does not rotate, and the outer ring portion 138R of the one-way clutch 136R on the right side is inadvertently inadvertent. It does not rotate easily, and the precision of dispatch movement is aimed at.

In addition, although the Example of the said invention described the riding type rice transplanter 1, this invention is not limited to a riding type rice transplanter.

Therefore, the granular material ejector of Claim 1 operates the counter arm 133 and the driven side rocking rod which operate to the drive side rocking rod 132 by the movement of the rotating shaft 162 according to the operation of the operation tool 159. FIG. By changing the swing angle of the feeding input arm 135 actuated to 134 to the side that increases or decreases together, the amount of the granules to be fed out of the granules extracting unit 61 can be changed and adjusted.
In addition, since the operating tool 159 and the feeding amount display port 174 are disposed in front of the powder dispensing unit 61, the feeding amount adjustment is performed from the front of the seat 31 side of the traveling vehicle body 2 in other words. At this time, the powder-feeding unit 61 is not obstructed, and the feeding amount can be easily adjusted. In addition, since the operating tool 159 and the dispensing amount indicator 174 are disposed at a relatively high position, it is difficult for the operating tool 159 and the dispensing amount indicator 174 to be caught by the powder, so that the feeding amount adjusting mechanism 156 ) Can be optimized. Further, the worker can easily visually check the feeding amount display tool 174 from the opposite side so that the powder dispensing portion 61 on the adjacent side is not obstructed.
