Description

DETAILED DESCRIPTION OF THE INVENTION The present invention detects when the number of seedlings in the main tank, which reciprocates laterally with respect to the seedling planting device, decreases below a predetermined amount, and synchronizes the sub tank with the main tank. In the case where the seedlings in the sub-tank are automatically fed into the main tank by moving the seedlings laterally and at the same time activating the forced feeding device, the sub-tank completes feeding the seedlings to the main tank and stops at a fixed position. The purpose of this is to quickly feed and supply the seedlings stored in the fuselage side to this sub-tank so that the work can continue for a long time without interruption, thereby increasing work efficiency.

The present invention will be described in detail below based on one embodiment shown in the drawings.

Reference numeral 1 designates a tractor as an example of a towing vehicle. At the bottom of this tractor 1, a rice transplanting machine 3 equipped with a float 2 that slides on the top soil of the paddy field is mounted and supported so as to be able to rise and fall. At the rear of the rice transplanting machine 3, a planting device is mounted. 4 are provided.

5 is a seedling planting device 4 supported tilted forward on the body 3;
The main tank for storing seedlings moves back and forth horizontally from side to side, and constantly moves back and forth laterally through a lateral movement mechanism linked to the prime mover. When the seedlings reach the seedlings, that is, when the planting device 4 picks out the first row of seedlings in the tank, the vertical feeder acts to vertically feed one pitch toward the planting device. .

Reference numeral 6 denotes a seedling storage sub-tank located above the seedling receiving side of the main tank 5, which is installed at the lateral center of the fuselage 3, and which has the same lateral movement range as the main tank 5 from the central position to the left and right. It is supported by rails 7 so as to be able to reciprocate in the lateral direction.

The lower side of the sub-tank 6 is equipped with a seedling-feeding device consisting of a seedling-feeding conveyor 8, etc., which forcibly feeds and supplies the seedlings housed in the tank 6 into the main tank 5, and receives power from a prime mover. A rotating input shaft 9, a clutch gear 11 mounted on the input shaft 9 so as to be slidable only in the axial direction via a spring 10, and a drive shaft 13 on which a transmission gear 12 meshing with the clutch gear 11 is mounted.
The delivery conveyor 8 is interlocked with the drive shaft 13 through a transmission chain 14 so as to rotate the delivery conveyor 8.

When the clutch gear 11 is shifted by the shifter 11a and disengaged from the transmission gear 12, the transmission to the delivery conveyor 8 is cut off and the stopped state is maintained.

15 is a detection mechanism that detects when the number of seedlings in the main tank 5 has decreased below a predetermined amount and sends an electric signal to a lateral movement mechanism for lateral movement of the sub-tank 6,
The detection plate 16 is held under tension via a tension spring 17 so as to be able to swing. When the number of seedlings in the main tank 5 decreases below a predetermined amount, the detection plate 16 is moved upward by the elastic action of the tension spring 17. to stand up and turn switch S1 to “O”.
It is set to "N".

When the main tank 5, which is always moving laterally, is laterally moved to the corresponding position of the sub-tank 6, which is stopped at a fixed position, the protrusion 18 provided on the main tank 5 side
presses switch button 19 and turns switch S2 ON
j, current is passed through the electromagnet 20 to excite it, and at the same time attracts the attracted body 21 provided on the side of the sub-tank 6, so that the sub-tank 6 moves laterally in synchronization with the main tank 5. Furthermore, the shifter 11 is
a is activated to engage the clutch gear 11 with the transmission gear 12, and the rotational power of the delivery conveyor 8-\ is continued to forcibly send out and supply the seedlings in the sub-tank 6 into the main tank 5. ing.

Then, when the main tank 5 is replenished with seedlings, the detection plate 16 is laid down against the tension spring 17, the switch S1 is turned l'-OFFj, and the sub-tank 6
The synchronized movement of the sub-tank with respect to the main tank 5 is canceled and the sub-tank is stopped at a fixed position in the center of this lateral movement path.At this time, when the sub-tank reaches the fixed position in the center, the fixed-position stop switches provided on both sides of the sub-tank are activated. A switch circuit (shown in FIG. 5) in which S3 and S4 become rOFFJ is incorporated, and during the reciprocating path other than this fixed position, the switch roller buttons 23 and 24 are connected to the guide plate 25 provided on the sub-tank 6 side.
The switches S3 and S4 are guided by the
It remains in the "ON" state.

Then, the switch circuit of the switches S3 and S4 is connected to the circuit between the electromagnet solenoid 20 and the tarlage solenoid 22, and when the switch S1 is turned on, r
OFFJ, when switch 81 is OFFj, "O
It is connected to a selector switch CS that switches to "N".

Reference numeral 26 denotes a seedling storage and mounting table provided on the machine body side, that is, on the tractor 1 side, for accommodating and placing several seedlings. A seedling feeding device consisting of a seedling feeding conveyor 27 with feeding claws 27a for feeding seedlings into the sub-tank 6 is provided on the lower side of the sub-tank 6. It is designed to be rotationally driven via a clutch 29.

Reference numeral 30 is a sensor installed at the front end of the seedling delivery side of the sub-tank 6 to detect the presence or absence of seedlings, and as shown in FIG. When the presence is detected, the detection switch 31
is turned “ON”, and after a predetermined time has elapsed by the timer 32, the timer switch TS is turned “ON”, and the solenoid 3
3, the electromagnetic clutch is engaged and the one-rotation clutch 29 is operated to rotate the seedling feeding conveyor 27 and feed one seedling on the seedling platform 26 into the sub-tank 6.

Since the present invention is configured as described above, if the prime mover now operates a predetermined device and moves the machine forward to start rice planting work, the main seedling storage tank 5 will always move back and forth horizontally in the left and right directions. The seedling planting device 4 picks out a predetermined amount of seedlings and inserts them into the soil. During such seedling planting work, if the number of seedlings in the main tank 5 decreases below a predetermined amount, the detection plate 16 detects this and turns switch S1 “ON”.
”.

Then, when the main tank 5 moves laterally to the corresponding position of the sub-tank 6 which is stopped at a predetermined position, the protrusion 18
presses switch button 19 and turns switch S2 “ON”
Then, current is passed through the electromagnet 20 and it is excited, so the object 21 on the side of the sub-tank 6 is attracted and becomes one piece.
The sub-tank 6 moves horizontally in synchronization with the horizontal movement of the main tank 5.

Simultaneously with the start of the lateral movement of the sub-tank 6, that is, at the same time as the electromagnetic force 20, the shifter 11a is actuated via the solenoid 22 which is excited, and the clutch gear 11 is shifted to mesh with the transmission gear 12, and the transmission is started. Turn on the transmission clutch of conveyor 8.

Therefore, the delivery conveyor 8 is rotationally driven through these transmission mechanisms, and the seedlings in the sub-tank 6 are forcibly delivered and supplied into the main tank 5.

When the main tank 5 is replenished with seedlings, the detection plate 16 is pushed down and the switch S1 is set to rOFFJ, and the renoid 22 is demagnetized, so the delivery conveyor 8
・At the same time, the rotational power of ＼ is cut off and stopped, and electromagnet 2
0 is also demagnetized, but at this time the switch S1 is
Since the selector switch CS is switched to "ON" by OFFj, when the sub-tank 6 is moving on the left side from the fixed position in the center, the switch S3 is in the "ON" state, and the right side is in the "ON" state. While moving, switch S4 is in the "ON" state and it is still moving laterally, and only after returning to the home position in the center are switches S3 and S4 set to 1'-O F'F j. Since the electromagnet 20 is demagnetized, the sub-tank 6 is released from integral lateral movement with respect to the main tank 5 and stops at a fixed position.

Then, the seedlings in the sub tank 6 are transferred to the main tank 5.
When the sub-tank 6 is refilled, the detection sensor 30 detects the sub-tank 6.
Detecting the absence of seedlings in the interior, the sensing switch 31 is turned on.
ON", and after a predetermined time has elapsed by the timer 32 (until the sub-tank 6 stops at the fixed position), the timer switch TS is turned on, the solenoid 33 engages the electromagnetic clutch, and the one-turn clutch 29 is activated to feed the seedlings. The conveyor 27 rotates within a predetermined range to feed and supply one seedling on the seedling mounting table 26 into the sub-tank 6.

Therefore, when the number of seedlings in the main tank 5 decreases below a predetermined amount, the seedlings in the sub-tank 6 are automatically replenished, and the seedlings stored on the aircraft side are automatically fed into the sub-tank 6. Therefore, seedling planting work can be continued for a long time without interruption.

It goes without saying that when the sub-tank stops at a fixed position, the seedling feeding and feeding device may be operated in conjunction with this to feed and feed the seedlings.

As described above, the present invention detects when the number of seedlings in the main tank that reciprocates laterally with respect to the seedling planting device decreases below a predetermined amount, synchronizes the sub tank with the main tank, and integrates the sub tank with the main tank. In a device that automatically replenishes the seedlings in the sub-tank into the main tank by moving the seedlings laterally and at the same time operating the forced feeding device, when the sub-tank completes sending out the seedlings from the main tank and stops at the fixed position. Since the system is structured so that the seedlings stored in the machine body are automatically fed and supplied into this sub-tank, automatic feeding and supply of seedlings from the sub-tank can be easily carried out, and moreover, it can be quickly and accurately adjusted. It also has the feature of allowing seedling planting work to continue for a long time without interruption, further improving work efficiency.
