The seedling box feeder 14 includes a seedling box manual feeding device 69 separately from the seedling box automatic feeding device 15. 12 and 13, reference numeral 70 denotes a manual feed rod, which has a manual feed claw 71 similar to the automatic feed claw 51 and a seedling box via a torque spring 75 on a roller shaft 74 provided at an intermediate portion of the manual lever 73. It is attached in a state of being urged toward the transport path. Normally, the manual feed rod 70 is at the home position shown in FIG. 12, and the manual feed nail 71 fits into the claw hole 308 of the seedling box and the manual feed nail at the cycle of moving the seedling box by one pitch p. 71 is swung so as to be pushed out from the claw hole 308. When the manual lever 73 is reciprocated within the range shown in FIG. 17, when the manual lever 73 rotates downward, the manual feed claw 71 pushes down the lower wall surface of the claw hole 308 to feed the seedling box 300 by one pitch p. Transport in the direction. When the manual lever 73 is moved slightly above the home position, the roller shaft 74 presses the upper portion 60a of the control rod 60, whereby the control rod 60 rotates counterclockwise, and the control claw 61 comes off the claw hole 308. Therefore, the seedling box can be transported by the manual seedling box feeding device 69.
[0024]
Further, when the manual lever is moved up to the position shown in FIG. 18 and the manual feed pawl 71 is engaged with the locking piece 76, the stop rod 60 is engaged with the engaging portion 50a of the automatic feed rod 50 and the automatic feed is performed. Since the rod 50 is rotated backward, the automatic feed claws 51 of the automatic feed rod 50 are also disengaged from the claw holes 308, so that the seedling box can freely fall.
[0025]
The manual feed rod 70 also serves as a stopper for preventing the seedling box from falling when the seedling box is loaded. 76
Is a stopper arm rotatably supported by a support shaft 77, and a bent end portion 76 a of the stopper arm is engaged with a projection 70 a formed on a side surface portion of the manual feed rod 70. The stopper arm 76 is provided on a path through which the ear 307 of the seedling box passes, and is urged by a spring 78 in a direction opposite to the feeding direction of the seedling box. When the seedling box 300 is present on the transport path, the stopper arm 76 is pushed by the seedling box 300 to the position shown by the chain line in FIG. 19, and the manual feed rod 70 is free. However, when the seedling box disappears on the transport path, the stopper arm 76 rotates to the position shown by the solid line in FIG. 19 due to the force of the spring 78, and the bent end portion 76a and the projection 70a engage. Operation is restricted. For this reason, if the seedling box 300 is loaded when the seedling box of the seedling box feed stand 14 is empty, the seedling box 300 is once received and held by the manual feed claw 71 of the manual feed rod 70. In this way, it is possible to prevent the seedling box from dropping abruptly to the lower part of the seedling box transport section 22 when the seedling box is loaded and causing trouble in the seedling and seedling box automatic feeder 15. If the manual feed rod 70 is slightly lifted by operating the manual lever 73, the bent end portion 76a of the stopper arm and the projection 70a are disengaged and the manual feed rod 70 becomes free, and the held seedling box falls. It becomes possible. When the seedling box falls, the stopper arm 76 is pushed to the position shown by the chain line.
[0026]
The rod 80 on which the spring 78 is loosely fitted is linked to the swing arm 53 by a connecting member 81. When the swing arm 53 swings upward, that is, when the automatic feed pawl 51 and the stop pawl 61 When is released from the claw hole 308, the spring 78 is pressed and contracted, and the urging force of the stopper arm 76 is increased. As described above, the seedling box 300 is held by the leaf spring brake 65 when the automatic feeding claw 51 and the stopping claw 61 are disengaged from the claw hole 308 immediately before the seedling feeding. However, it cannot be supported by the leaf spring brake 65 alone. Therefore, at this time, the stopper arm 76 acts as a brake for preventing the upper seedling box from going down, and assists the leaf spring brake 65.
[0027]

For this reason, the seedling box 300 initially placed on the seedling box placing part 21 (B) in the lower stage is supplied to the seedling box transport part 22. When the supply of the seedling boxes of the lower seedling box mounting portion 21 (B) is completed and the rear end of the seedling box 300 passes through the stopper arm 76, the switching stopper 90 rotates to the position indicated by the solid line in conjunction with the stopper arm 76. Since the seedling box transport path is opened, the seedling boxes placed on the upper seedling box placing portion 21 (A) are supplied to the seedling box transporting portion 22.
[0028]
A sensing switch 93 for sensing the presence or absence of a seedling box is provided between the manual feed rod 70, which is a stopper for preventing falling, and the seedling pushing position 27, and the detection result is displayed on, for example, a seedling reduction lamp 94 of a center mascot. It has become. When the seedling reduction lamp 94 is turned on, the operation is stopped, a new seedling box is supplied to the seedling box mounting unit 21, and the empty boxes loaded in the empty box storage unit 23 are removed. If the sensing switch 93 is provided at the position of the present embodiment, seedlings can be replenished before the seedlings completely disappear, so that planting shortage is prevented, and the manual feed rod 70 functions as a stopper. Since the sensing switch 93 senses that the seedlings have decreased when it is present, the replenished seedling boxes can be temporarily received by the manual feed rod 70, and the displacement of the seedling boxes due to impact or the like can be prevented. In the present invention, since the empty box storage section is disposed below the start end of the seedling box transport path, both the supply operation of the seedling boxes and the empty box collection operation can be performed efficiently.

The seedling strike mounting arm 120 is operated via a seedling strike rod 121. 122 is a return spring.
[0035]
When the seedling transfer arm 111 is at the J position, the seedlings 310,... Pushed out of the seedling box 300 by the seedling pushing pins 100,. The seedling transfer arm 111 rotates to the K position, and advances to the L position there. Since the seedlings 310,... Are received by the seedling striker portion 118a, the seedlings 310,. At about the same time, the seedling hitting tool 117 moves down, hitting the seedlings 310,... Since the seedling transfer device 17 operates at a half cycle of the seedling pushing device 16, the seedling pushed out by the inner seedling pushing pin 100 and the seedling pushed out by the outer seedling pushing pin 100 are alternately placed in the seedling transport belt. 18 will be delivered.
[0036]
FIG. 26 is a side view of the seedling transport belt, and FIG. The seedling transport belt 18 is a pair of right and left symmetrical timing belts 130 (L) and 130 (R) stretched in a right-angled triangle. The three roller shafts 131 (1, 2, 3) that stretch the timing belt 130 are slanted such that the front part is lower, and the seedling transport belt 18 is supported in a state of falling forward in a side view. . It has a relatively wide belt width that can cover from the floor soil portion 310a of the seedling 310 to the tip of the leaf 310b. Are provided at equal intervals q in the circumferential direction, and a floor is provided at the lower end edge of the timing belt at a position shifted from the separate protrusions 133 by 1/2 of the interval q in the circumferential direction. .. Are provided to receive the bottom of the soil portion 310a. The roller shaft 131 (1) at the lower portion on the center side is the drive shaft, and both timing belts 130 (L) and 130 (R) always move in the direction of the arrow in FIG. The left and right timing belts 130 (L) and 130 (R) are separated by an interval 136 through which one seedling can pass, and the lower end of the interval 136 is a seedling opening 137. A pair of left and right rubber guides 138, 138, which temporarily hold the seedlings and serve as guides when the implanting rod 141 clamps the seedlings, are attached to the seedling opening 137.
[0037]
The seedling group (seven) in the left half of the seedling box transferred by the seedling transfer device 17 is placed on the upper side of the left timing belt 130 (L), and the right half seedling group (seven) is placed in the right timing belt. 130 (R) is placed on the upper side. The delivery of the seedlings is performed alternately on the left and right. The seedlings 310,... Placed on the upper side of the right or left timing belt 130 are conveyed inward with the movement of the timing belt 130, and then conveyed downward through the interval 136 between the left and right timing belts. 137 are supplied one by one (see FIG. 28). When the last one of the seedlings is transported to the interval 136, the seedlings 310,... Are placed on the other timing belt 130 (see FIG. 29). As described above, the right and left timing belts are constantly moved and the left and right seedlings are alternately transferred, so that the seedlings are continuously supplied to the seedling outlet 137. Since the roller shaft 131 (1) of the three roller shafts, which is located near the seedling opening 137, is driven, there is little deviation in seedling supply timing.
[0038]
The implanting device 12 has a pair of implanting rods 141 and 141 attached to a rotary case 140 that rotates about an implanting device attachment shaft 158 described later. The implantation rod 141 includes a seedling holding claw 142 and a seedling pushing tool 143, and the implantation rod moves up and down while drawing a predetermined locus 144, and the seedling holding claw 142 is located at a seedling picking position above the locus. By holding the seedlings supplied to the opening 137 and pushing out the seedlings that the seedling pusher 143 protrudes from the lower part of the locus, the seedlings are planted one by one in the field scene. .
[0039]
As shown in FIGS. 30 and 31, the rubber guide 138 has a
The free end side is attached to the support frame 18 and extends forward and downward along the locus 144 of the seedling holding claws. On the inner surface of the rubber guide 138, a groove-shaped slit 146 and a fold-shaped rib 147 are formed in the front and rear directions in a direction intersecting the locus 144. The seedlings dropped from the seedling transport belt 18 are supported by the ribs 147 and 147, and the seedling holding claws 142 enter there to pinch the seedlings. The seedling holding claws 142 holding the seedlings are rubber guides 138 and 138. Move while pushing the tip of the. Since the seedlings are once supported by the ribs 147, 147, the interval r between the bases of the rubber guides 138, 138 can be widened, and the dropping of the seedlings is reliable. Since the tip of the seedling holding claw 142 contacts the thin and soft rib 147, the rubber guide 138 is less likely to be damaged. Further, by providing the slits 146, even if the distal ends of the rubber guides 138, 138 are pushed open, the base is not affected, and the seedlings at the seedling opening 137 can be prevented from falling. The timing is set such that the next seedling is dropped into the seedling opening 137 when the implantation rod 141 passes through the rubber guides 138.
[0040]
As shown in FIGS. 32 and 33, the transmission case 10 includes an input case 151 rotatably attached to a rear frame 5a of the link device 5 by a rolling shaft 150, and transmission pipes 152 protruding from both side surfaces of the input case. , 152, and a total of three L-shaped cases 153 extending rearward from the center of the input case 151 and the distal ends of the transmission pipes 152, 152. The L-shaped case 153 includes a horizontal portion 153a extending horizontally and a rising portion 153b rising vertically from the rear end of the horizontal portion. The planting devices 12, 12 are provided on both sides of the rear portion of the horizontal portion 153a, and the rising portion is provided. At the upper end of 153b, a transmission box 153c for transmitting to each part of the two-row seedling supply devices 11, 11 is provided.
[0041]
Power is input from the machine 2 via a universal joint 156 to a main shaft 155 supported in the input case 151 and the transmission pipes 152 and 152, and the planting is supported from the main shaft to the rear part of each L-shaped case horizontal portion 153a. It is transmitted to the device mounting shaft 158 via the chain 159. The transmission is transmitted from the planting device mounting shaft 158 to the counter shaft 160 provided at the rear thereof via gears 162 and 163, and further transmitted from the counter shaft 160 via the chain 164 to each shaft in the transmission box 153c. I have.
[0042]
FIG. 34 is an exploded cross-sectional view of the transmission box. In the transmission box 153c, the seedling conveyor belt drive shaft 170, the seedling transfer device drive shaft 171 and the seedling box feed drive shaft 172, which always rotate in a fixed direction, and A seedling transfer arm slide shaft 174, a seedling pushing pin operating shaft 175, and a seedling feed operating shaft 176 that are intermittently and repeatedly rotated by being driven by a cam are supported. 178, 179, 180, and 181 are transmission gears that are transmitted in the order of a seedling transport belt drive shaft 170, a seedling delivery device drive shaft 171, and a seedling box feed drive shaft 172. The rotation speed of the delivery device drive shaft 171 is equal, and the rotation speed of the seedling delivery device drive shaft 171 is set to twice the rotation speed of the seedling box feed drive shaft 172.
[0043]
The seedling transport belt drive shaft 170 drives, via bevel gears 186 and 187, a total of four roller shafts 131 (1) provided for two rows provided in a direction orthogonal to this. A pair of roller shafts 131 (1) and 131 (1) of each strip rotate in directions opposite to each other.
[0044]
One end of the seedling transfer device drive shaft 171 protrudes out of the case, and a seedling transfer arm rotating crank 190 is attached thereto. The swing mechanism of the seedling transfer arm will be described with reference to FIG. A swing arm 191 is provided integrally with the rotation shaft 114, and a pin 193 having a guide hole 192 is rotatably supported on the swing arm. A transmission rod 195 whose one end is rotatably connected to the crank 190 is slidably inserted into the guide hole 192. Springs 196 and 197 are loosely fitted on both sides of the transmission rod 195 with the pin 193 interposed therebetween, so that the positional relationship between the transmission rod 195 and the pin 193 can be elastically varied. In addition, a stopper rod 201 having stopper rubbers 199 and 200 fitted thereto at predetermined intervals is provided rotatably about a fulcrum 202 alongside the transmission rod 195. When the crank 190 rotates, the swing arm 191 swings and the seedling transfer arm 111 moves up and down. However, since the swing range of the swing arm 191 is regulated by the stopper rubbers 199 and 200, the seedling transfer is performed. The upper limit position of the arm 111 is J, and the lower limit position is K. The excess of the crank operation is absorbed by the springs 196 and 197. Therefore, the vertical movement of the seedling transfer arm 111 stops at the fixed position J at the seedling receiving position J and the seedling discharging position K, and the seedling transfer can be performed reliably.
[0045]
The seedling transfer arm slide shaft 174 is rotated repeatedly by the rotation of the seedling transfer device drive shaft 171 transmitted by the slide cam 210 and the cam follower 211. Then, the repetitive operation of the slide arm 213 provided on the protruding portion of the seedling transfer arm slide shaft 174 is transmitted to the rollers 214, 214 supported by the seedling transfer arm support shaft 111a, and the seedling transfer arm support shaft 111a is moved to the rotating frame 115. And slide it. The slide cam 210 and the cam follower 211 act to rotate the seedling transfer arm slide shaft 174 in the pushing direction, and are rotated by the spring 215 in the returning direction. The slide arm 213 includes an extruding arm 213a fixed to a seedling transfer arm slide shaft 174 and a return arm 213b attached to the extruded arm by a coil spring 217. The rollers 214, 214 escape toward the return arm 213b. Is provided.
[0046]
Further, a seedling hitting cam 220 is provided integrally with the crank 190. The cam 220 and the cam follower roller 221 swing the seedling hitting arm 222 to drive the seedling hitting rod 121. Also in this case, the seedling hitting tool 117 is driven to the working side by the spring 225, and the seedling hitting tool 117 is returned to the original position by the seedling hitting cam 220 and the cam follower 221.
[0047]
By the way, there is a necessity that the operation of the seedling hitting tool 117 must be performed instantaneously. Therefore, the driving mechanism has a configuration shown in FIG. That is, the cam 220 includes a peak 220a and a valley 220b, and when the roller 221 falls from the peak 220a into the valley 220b, the spring 225 causes the seedling hitting arm 222 to rotate in the direction of the arrow. The amount of movement of the seedling hitting arm 222 required for hitting the seedling is α1, and the rotation angle of the cam 220 required for it is β1. However, when the roller 221 passes through the corner 220c, a sufficient amount of operation of the seedling arm 222 cannot be obtained with respect to the rotation amount of the cam 220. The operation range α2 (rotation range β2 of the cam 220) is such that the seedling striker 117 does not operate.
[0048]
The seedling pushing pin operating shaft 175 has an inner (I) and an outer (O) shaft, and both shafts are supported concentrically and rotatable with each other. The seedling pushing rod 109 (I) is attached to the seedling pushing arm 230 (I) of the inner seedling pushing pin operating shaft 175 (I), and the seedling pushing of the outer seedling pushing pin operating shaft 175 (O). A seedling pushing rod 109 (O) is attached to the arm.
[0049]
The drive mechanism of the seedling push pin operating shaft 175 is configured as shown in FIG. Reference numeral 232 denotes an extrusion cam attached to the seedling transfer device drive shaft 171, and the inside (I) and outside (O) are in phase. Reference numeral 233 denotes an extrusion stopper attached to the seedling box feed drive shaft 172, and the phases of the inside (I) and the outside (O) are shifted by 180 degrees. 234 (I) and 234 (O) are roller support arms provided in the same phase on the inner and outer seedling pushing pin operating shafts 175, respectively, and correspond to the roller 236 corresponding to the pushing cam 232 and the pushing stopper 233. Rollers 237 are rotatably supported. The roller support arm 234 is urged by a spring 238 to the side where the roller engages with the cam, and when the roller support arm 234 is pulled toward the seedling transfer device drive shaft 171 by the spring, the seedling pushing pin 100 projects. It has become.
[0050]
When the extruding cam ridge 232a is engaged with the roller 236 or when the extruding stopper ridge 233a is engaged with the roller 237, the roller support arm 234 is positioned at the outer side 234 (O) in the drawing. So that the seedling push-out pin 100 does not protrude, so that the seedling push-out pin 100 projects when the valley 232b of the extrusion cam engages with the roller 236 and the valley 233b of the extrusion stopper faces the roller 237. Become. Since the rotation speed of the seedling delivery device drive shaft 171 is twice the rotation speed of the seedling box feed drive shaft 172, the extrusion stopper 233 makes one rotation while the extrusion cam 232 makes two rotations. Therefore, each time the seedling box feed drive shaft 172 makes one rotation, the seedling pushing pin 100 projects at a rate of once. Also, since the inside and outside push-out stoppers 233 (I) and 233 (O) are out of phase by 180 degrees, the inside and outside seedling push-out pins are out of phase by 180 degrees. And protrude alternately. The timing at which the peak 233a and the trough 233b of the extrusion stopper 233 (I, O) face the roller 237 is shown in the timing of FIG.
[0051]
Rotation is transmitted from the seedling box feed drive shaft 172 to the seedling feed operation shaft 176 via a seedling feed cam 240 and a cam follower 241. A frame-shaped seedling feeding operation arm 242 is attached to both left and right protruding portions of the seedling feeding operation shaft 176, and a rear end of the seedling feeding rod 58 is rotatably connected to one end of the seedling feeding operation arm 242. At the same time, a spring 243 acting in a direction to push the seedling feed rod 58 forward is connected to the other end. (See FIG. 2) The rotation of the seedling feed swing arm 53 in the seedling feed direction is performed by a spring 243, and the rotation in the return direction is performed by a seedling feed cam 240 and a cam follower 241.
[0052]
The drive mechanism of the seedling supply device 11 is configured as described above, and each part of the seedling box automatic feeding device 15, the seedling pushing device 16, the seedling delivery device 17, and the seedling transport belt 18 operates in synchronization with each other. . Since these components are transmitted by a common shaft (seedling conveyor belt driving shaft 170) provided at the end portion of the transmission case 10, the phase is not shifted, and an accurate seedling supply operation is always performed. Can be. In addition, since each of these parts is configured so that the operation on the operation side is performed by a spring and the operation on the return side is performed by a cam and a cam follower, the operation operation is quick and accurate, and the cam is downsized. I have.
[0053]
FIG. 37 is a timing chart showing the operation timing of the seedling supply device 11 and the planting device 12. This figure means the following.
[0054]
(1) Seedling positions a1 to a14 indicate the timing at which the seedling holding 142 claws of the implantation rod 141 pass through the seedling collecting hole 137.
[0055]
(2) The “planting rod stop positions” b1 to b14 are timings at which the planting device 12 stops when the planting clutch is disengaged, and the planting rod 141 stops at a position slightly past the seedling opening 137.
[0056]
(3) "Seedling box feed" indicates the operation of the automatic feed claw 51, the upward movement is started at c1, the operation is switched to the downward movement at c2, and the operation is stopped at c3. When the automatic feed claw 51 moves down, the seedling box is moved by one pitch.
[0057]
(4) With regard to "seedling pushing", the seedling pushing pin 100 protrudes between d1 and d2, and the seedling pushing pin 100 retreats between d3 and d4. The operation phases of the inner seedling pushing pin 100 (I) and the outer seedling pushing pin 100 (O) are shifted by 180 degrees. Immediately before starting the seedling box feed, the operation of the inner seedling pushing pin 100 (I) is completed.
[0058]
(5) Regarding the "seedling transfer arm rotation", the seedling transfer arm 111 moves downward between e1 and e2, and the seedling transfer arm 111 moves upward between e3 and e4. Although it cannot be clearly identified from the timing chart in the figure, the operation speed is slightly slower when moving down than when moving up. The reason for this is to prevent the seedlings held in the seedling holder 110 from being released or displaced.
[0059]
(6) Regarding the “seedling delivery arm slide”, the seedling delivery arm 111 moves forward between f1 and f2, and retreats between f3 and f4. In order to ensure that the seedlings can be extracted from the seedling holder 110, the forward speed is lower than the retreat speed. This sliding operation is performed while the seedling delivery arm 111 is at the down position.
[0060]
(7) With regard to “sapling of seedling”, the seedling striker 117 moves downward between g1 and g2, and moves upward between g3 and g4. This seedling beating operation is performed while the seedling transfer arm 111 is stopped at the forward position.
[0061]
(8) The seedling transfer arm rotating operation, the seedling transfer arm sliding operation, and the seedling beating operation are performed twice in one cycle, and the phases of both operations are shifted by 180 degrees. The seedlings pushed out by the outer seedling pushing pins 100 (O) in the first operation are transferred to the seedling transport belt 18, and the seedlings pushed out by the inner seedling pushing pins (I) in the second operation are transferred to the seedling transport belt 18. Hand over to
[0062]
(9) When the operation is stopped, the implantation rod 141 stops at any of the implantation rod stop positions b1 to b14. However, when the seedling pushing pin 100 is inserted into the pot of the seedling box, the implantation rod 141 is stopped. The seedling box cannot be removed. Therefore, it is convenient to provide a seedling box extraction OK lamp 245 in the cockpit, which indicates that the seedling pushing device 16 is inactive and the seedling box can be extracted. The seedling box extraction OK lamp 245 is switched by, for example, a seedling pushing operation display switch 246 (shown in FIG. 34) which is turned on when the seedling pushing arm 230 is not operating, and is turned on when d4-d1. Otherwise, it is turned off.
[0063]
(10) By setting the operation start timings of the seedling box feeding and the seedling pushing (inside) to be almost the same, the stopping claw 61 is set after the tip of the seedling pushing pin 100 is completely inserted into the seedling pushing hole 303 (d5). A slight time difference (about 18 degrees and 30 minutes) occurs before the seedling box falls out of the claw hole 308 of the box (c4), thereby preventing the seedling box from falling downward.
[0064]
(11) While the automatic feed claw 51 is moving upward (c1-c2), the seedling pushing pins 100 inside or outside (inside in the illustrated example) move forward and backward. When the automatic feeding claw 51 starts to move upward, the stopping claw 61 is released, and the seedling box is in a state of being stopped by only the leaf spring brake 65. At this time, if the seedling pushing pin 100 is inserted into the seedling pushing hole 303 of the seedling box, the seedling box will not slip even if a sudden external force or vibration is applied.
[0065]

Is provided. Each of the floats 250 (L, C, R) has a wide front portion and a narrow rear portion, and is provided with groove forming devices 251 for forming grooves for transplanting seedlings on both left and right sides of the rear portion. The float 250 (L, C, R) is pivotally connected to a rear end of a float support rod 252 rotatably provided on the transmission case 10 up and down by a support pin 254, and a front part is expanded and reduced by a link 255. It is suspended, and the front part moves up and down according to the unevenness of the paddy surface.
[0066]
The center float 250 (C) is a sensor for detecting the paddy field height,
The spool of the hydraulic valve 257 for controlling the hydraulic cylinder 6 is switched based on the vertical movement of the port, and the planting section 3 is controlled to be at a constant height with respect to the paddy field surface. For this reason, the planting depth of the seedlings is always kept constant. By turning the float support rod 252 to change the support height of each float, the planting depth of the seedling can be adjusted.
[0067]
The fertilizer applicator 4 includes a hopper 260 that stores fertilizer, a feeder 261 that feeds the fertilizer in the hopper downward, and a fertilizer pipe 262 that guides the fertilizer fed from the feeder to a groove for planting seedlings. ing. The fertilizer pipe 262 extends downward from the feeder along the lower surface of the empty box collection unit and the front surface of the seedling box feeder 14, and further extends to the lower end of the seedling box feeder 14 and the input case 151 of the transmission case 10 or the transmission. The fertilizer discharge port 263 extends rearward between the pipes 152 and 152, and faces the field scene inside the groove generator 251.
[0068]
At the time of the planting operation, the planting section 3 is lowered to the work position shown in FIG. Fertilizer is supplied to the ditch for planting seedlings, and seedlings are planted immediately thereafter.
