Arranged in the left and right directions to perform maintenance and repair of the fertilizer discharging portions 61,. When does not become an obstacle. Moreover, the supporting member can be arranged without difficulty.

As shown in Fig. 16, the hopper supporting pivoting arm 71 is rotated at the lower end of the corrugated box-shaped deformable connecting boot 160 connecting the fertilizer hopper 60 and the fertilizer discharging portion 61 to each other. If the support point is provided, the connection boot 160 can be hardly pulled out.

The discharge part 61 incorporates two discharge rolls 73A and 73B for discharging the fertilizer in the fertilizer hopper 60 downward. These discharge rolls 73A and 73B are rotating bodies having groove-shaped recesses 74, ... formed in the outer circumference thereof, and each shaft portion 75a of the common discharge shaft 75 provided in the left and right directions. (In the example shown in the figure) are fitted to rotate integrally. As the discharge rolls 73A and 73B rotate in the direction of the arrow in Fig. 7, the fertilizer drop-fed from the fertilizer hopper 60 is accommodated in the recess 74 and discharged downward. The fertilizer discharged by the said both discharge rolls 73A and 73B is discharged from the discharge port 61a of the lower end.

The number of the recessed parts of the discharge rolls 73A and 73B of the example shown is six, and the phase of both recessed parts differs. For this reason, the recessed part of both discharge roll 73A, 73B discharges a fertilizer alternately, and the quantity of the fertilizer discharged from the discharge port 61a is equalized in time. It is also possible to make the phase of the recessed part of both discharge roll 73A, 73B the same by removing any discharge roll from the discharge shaft 75, changing a phase suitably, and installing again. Therefore, it becomes applicable in the case of spraying fertilizer in the form of spots on the rice fields.

Moreover, in the inside of the discharge part 61, the brush 76 which contacts the outer peripheral surface of the discharge roll 73 of the side (front side) in which the recessed part 74 moves downward is attached and detached freely. The fertilizer is accommodated in the state in which the surface was leveled in the recessed part 74 of the discharge roll 73A, 73B by the said brush 76, and the discharge amount of the fertilizer by the discharge roll 73A, 73B is kept constant.

It is installed. The discharge stop shutters 77A and 77B are freely supported by the slide support part 79 of the discharge part case 78, and are made to slide by holding the handle 77a formed in the front end of the case outside.

The connection pipe 80 communicated in the front-back direction is connected to the discharge port 61a of the discharge part 61. Then, the sheath hose 62 is connected to the rear end of the connecting pipe 80. Since the lower end of the fertilizing frame 70 is coupled to the outer circumferential spiral groove of the fertilizing hose 62, the fertilizing hose 62 is hard to be pulled out of the connecting pipe 80. On the other hand, the front end part of the connection pipe 80 of each tank is inserted and connected to the back part of the air chamber 68. As shown in FIG. The left end of the air chamber 68 is connected to the blower 67 via an air switching pipe 81, and air from the blower is connected to the blower hose from the connecting pipe 80 via the air chamber 68. It is intended to be blown at 62.

The air chamber 68 alternately consists of a rubber tube 68a provided with a connecting tube 80 and a resin tube 68b of an intermediate portion. With this configuration, since the air chamber 68 can be easily disassembled and assembled, the maintenance and repair in the state where the discharge part 61 is detached integrally is easy. If the length of the rubber tube 68a is made longer than the space | interval of a pair of discharge part, the rubber tube 68a is easy to be pulled out from the resin tube 68b.

Further, a fertilizer discharge port 83 for discharging the fertilizer in the fertilizer hopper is formed at the rear portion of the discharge portion case 78. The fertilizer discharge port 83 is provided with a discharge shutter 84 that can be opened and closed with its upper end as a support point. The fertilizer discharge port 83 of each discharge part is connected to the fertilizer recovery pipe 85 long in the left-right direction provided in the back of the discharge part 61. As shown in FIG. The left end of the fertilizer recovery pipe 85 is connected to the blower 67 via the air switching pipe 81. The air switching tube 81 is a two branched tube, one of which is connected to an air chamber 68 and the other of the fertilizer recovery tube 85. An air switching shutter 86 is installed in the air switching pipe 81 to switch between supplying air from the blower 67 to the air chamber and supplying to the fertilizer recovery pipe. The right end of the fertilizer recovery pipe 85 is a fertilizer recovery port 87.

Fig. 9 is a diagram showing the opening and closing mechanisms of the above-mentioned shutters 84, ..., 86. The fertilizer recovery lever 90 is freely rotatable in the vicinity of the fertilizer recovery port 87. On the same axis as the pivot point axis 90a of the fertilizer recovery lever 90, a shutter opening / closing transmission shaft 91 elongated in the left and right direction disposed in front of the discharge portion 61 is provided. A fan-shaped plate 92 is provided on the shutter opening / closing transmission shaft 91 and pins fixed to the fertilizer recovery lever 90 in an arc-shaped long hole 92a formed in the fan-shaped plate 92. 90b is loosely fitted. The shutter opening / closing transmission shaft 91 is provided with an opening / closing gear 93 for each discharge portion, and the gear meshes with the semi-circular gear 94 provided on the rotation shaft 84a of the discharge shutter 84. Moreover, since the stopper part 94a which is larger in diameter than this of the said gear is formed in the edge part of the said semi-circular gear 94, the meshing of both gears will not fall out. In addition, one end of the air conversion wire 95 is connected to the fertilizer recovery lever 90. The other end of the air switching wire 95 is connected to the arm 96 provided on the pivot shaft 86a of the air switching shutter 86 via a tension spring 97.

When the fertilizer recovery lever 90 is rotated, the air switch wire 95 is pulled to switch the air switch shutter 86, and the air from the blower 67 is supplied to the fertilizer recovery pipe 85. While the fertilizer recovery lever 90 has a small rotational operation amount, since the pin 90b only moves in the long hole 92a, the shutter opening / closing transmission shaft 91 does not rotate. However, when the fertilizer recovery lever 90 is rotated by a certain amount or more, the pin 90b is caught by the fan-shaped plate 92, and the shutter opening / closing transmission shaft 91 rotates. As a result, the discharge shutters 84,... Open, and the fertilizer in the fertilizer hopper 60 is discharged to the fertilizer recovery pipe 85. That is, the air switching shutter 86 and the discharge shutters 84,... Can be operated by only one lever operation. Moreover, inevitably, air is first supplied to the fertilizer recovery tube 85, and then the fertilizer is discharged to the fertilizer recovery tube 85. For this reason, conveyance of the fertilizer in the fertilizer collection pipe 85 is performed smoothly, and clogging of the fertilizer in the fertilizer recovery pipe 85 does not occur. In addition, since the fertilizer recovery lever 90 is provided in the vicinity of the fertilizer recovery port 87, the fertilizer recovery container and the like can be easily secured to the lower side of the fertilizer recovery port 87. You can work while checking.

The fertilizer recovery lever 90 is pivotally operated along the lever guide 98. Guide levers 98a and 98b are formed in the lever guide 98, and the engaging portion (not shown) of the fertilizer recovery lever 90 is guided using the bending of the fertilizer recovery lever 90. , 98b) to switch the fertilizer recovery lever 90 to the position P1 where only the air conversion shutter 86 is switched, and both the air conversion shutter 86 and the discharge shutter 84,... It can be fixed at the position P2.

The discharge part case 78 is divided into the lower fixing part 78a and the upper leaving part 78b in the dividing surface F-F which inclined downhill as viewed from the side. The discharge 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 discharge stop shutter 77 are provided in the detachment part 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 maintained well.

When the fertilizer hopper 60 is rotated to the rearmost side, the fertilizer hopper is positioned outside the area projected in the direction from which the detaching portion 78b is separated from the side. For this reason, the leaving part 78b can be separated easily. In addition, the extending end of the divided surface FF is located below the upper end of the air chamber 68, and the air chamber 68 is located outside the region projected in the direction from which the detaching portion 78b is separated from the side. . For this reason, the maintenance and repair of the discharge rolls 73A and 73B can be made easy from above the traveling vehicle body 2 in the state which detached | separated part 78b was removed.

Next, the fertilization transmission mechanism 27 will be described.

The eccentric gears 138 and 139 are combined so that the parent implant 52a operates fastest near the bottom dead center of the movement trajectory T which the parent implant 52a draws. As a result, the transplant graft 52a is dragged in the soil to make the graft trace as small as possible, and at the same time, when the hair is taken out from the hair outlet 51a, the movement speed of the mother loading table 51 is slowed down. Moreover, since the mother implant part 4 and the fertilizer 5 are driven by the power shifted between aerations, it can fertilize appropriately between aerations.

The fertilizer main body described above is supported by the fertilizing frame 70 fixed to the upper end of the link base frame 42. In detail, the discharge portions 61,... Of the tanks are installed on the fertilizing frame 70 with the bolts 151 via the spacers 150, and as described above, the fertilizing frame ( The fertilizer hopper 60 is rotatably supported to the rear by the two left and right pivotal arms 71 provided at 70). Although the discharge part 61 can be divided up and down, in some cases, it is also possible to remove the bolt 151, and to remove the discharge part 61 integrally. Before and after the fertilizing frame 70, the air chamber 68 and the fertilizer recovery pipe 85 are provided, and they serve as a frame and contribute to the improvement of the overall strength. By disposing the discharge portion 61 by an electric path passing through the back of the fertilizer recovery tube 85 from the side, it is possible to bring the discharge portion 61,... And the fertilizer recovery tube 85 into close proximity. This helps to improve the supporting strength of the discharge portion.

In the case of the present invention, the hopper can be rotated to the rear to easily release the disengaging portion from the discharge portion, and the maintenance and repair of the member housed in the discharge portion can be facilitated. In particular, when the detachment part is detached from the fixed part of the discharge part, the detachment part can be easily detached so as not to interfere with the hopper.

Moreover, in the case of this invention, since the discharge shutter which opens and closes a discharge port exists in the fixed part of a discharge part, the structure of a separation part is simplified.

In addition, in the present invention, when the ejection part is separated and the detachment part is separated, the brush for leveling the surface of the granular material accommodated in the recessed part of the rotating body is removed together with the ejection part of the ejection part. It can be performed easily.

In addition, in the case of the present invention, the discharge portion can be detached and separated from other parts of the powder-discharging machine, and the maintenance and maintenance of the discharge portion can be facilitated. Moreover, since the whole discharge part and the case where only a part of the discharge part is removed can be selected according to the location or type of maintenance and repair, the overall maintenance and repair becomes easy.

In addition, in the case of the present invention, the structure in which the air chamber is detachable is easily deformed with respect to other parts, so that the connection between the discharge portion and the air chamber and the attachment and detachment of the discharge chamber are facilitated.
