[0003]

However, in the case where the carrier containing seedlings is sent to the rice transplanter and the empty carrier is collected from the rice transplanter with a single conveyor as in the conventional example, the carrier containing seedlings is sent. There is room for improvement in terms of work efficiency because it is not possible to collect carriers with seedlings at the same time.
Also, in the case of collecting the empty carriers in a piled state from the seedling transplanter, the recovery efficiency can be improved, and the handling of the empty carriers is improved compared to the case of handling one by one, but on the seedling transplanter side. Since it is necessary to provide a stacking mechanism, the seedling transplantation machine cannot be increased in size, and there is room for improvement in this respect as well.

An object of the present invention is to provide a seedling replenishing device for promptly feeding a carrier containing seedlings to a seedling transplanting machine and collecting empty carriers from the seedling transplanting machine, and improving the handleability of the recovered empty carriers. The point is to make a rational arrangement.

[0005]

A feature of the present invention is that a conveyor mechanism for feeding a seedling-containing carrier from a storage portion for supplying seedlings to a spare seedling storage portion of a seedling transplanter is provided with a conveyor mechanism for feeding a seedling-containing carrier. 1 transport unit and a second transport unit for collecting empty carriers from the seedling transplanter arranged above or below the transport unit, and the second transport unit is provided with a second transport unit adjacent to an end on the lower transport side. The carrier recovery unit is provided with a carrier recovery unit that stacks a predetermined number of empty carriers from the transport unit and sends out the stacked carriers that have reached a predetermined number in the lateral direction. The operation and effect are as follows.

[0006]

According to the above feature, in the present invention, since the conveyor mechanism is configured to include the first transport section and the second transport section, the seedling-containing carrier can be replenished and the empty carrier can be recovered at the same time to improve the work efficiency. When collecting empty carriers from the seedling transplanter to the seedling replenishing device, the empty carriers sent through the second transport section of the conveyor mechanism reach a predetermined number in the carrier collecting section. After being automatically stacked, they are fed out in the lateral direction, so that it is possible to obtain empty carriers in a stacked state without imposing a burden on the worker. Further, according to the present invention, since the first carrying section and the second carrying section are arranged vertically, the size of the conveyor mechanism can be reduced while improving the strength in the direction of gravity as compared with the case where the first carrying section and the second carrying section are arranged side by side. Enable

[0007]

This rice transplanter is configured to store the seedling-containing carrier A in the spare seedling storage portion J, and if the seedlings on the seedling placement table 69 are insufficient during the work, the automatic seedling feeder K stores the spare seedlings. The carrier A containing the seedlings of the part J is taken out, only the mat-like seedlings W are sent to the seedling placing table 69, and the empty carrier A from which the seedlings are taken out is automatically returned to the original position of the spare seedling storage part J. It is configured.

When the seedlings in the spare seedling storage section J of the rice transplanter are reduced and seedlings are supplied, as shown in FIG. 1, the front part of the traveling machine body 68 is set at the position close to the ridges by the seedling supply device. The vehicle is stopped toward the side, and first, the connection member 46 of the conveyor mechanism F is connected to the seedling supply unit L. At the time of this connection, an optical sensor (not shown) provided at the tip of the conveyor mechanism F is used for the seedling replenishment section L.
A light source (not shown) provided for the second hydraulic cylinder LC2 is captured, and a turning operation by the second hydraulic cylinder LC2 and an up-and-down operation by the operation of the third hydraulic cylinder LC3 are performed with the light source as a target to connect them at appropriate relative positions. Also, at the time of this connection, the fourth conveyor F
4 is made to stand by at the back position, the connection member 46 is exposed, and when the connection is completed, the fourth conveyor F4 is moved forward to form a conveyance path.

Next, positioning control is performed in which the transverse feed mechanism D is moved up and down to the level of the seedling-containing carrier A to be taken out at the portion of the shelf-like storage B, and the taking-out mechanism C is moved to the row of the seedling-containing carriers A to be taken out. After that, the take-out mechanism C is operated to perform take-out control for taking out the seedling-containing carrier A. At the time of this take-out, as shown in FIG. 6A, the take-out frame 22 is moved to the side of the shelf-shaped storage section B by the operation of the first air cylinder AC1, and the second air cylinder AC2 is actuated. At the beginning of the operation, as shown in FIG. 6B, the locking piece 23 moves in the substantially horizontal direction in the direction of the carrier A, and thereafter, is displaced upward and the end formed by projecting on the outer frame 2 of the carrier A. At the same time that the locking piece 23 is engaged with the portion 2B, the end portion of the carrier A is lifted up to the level of overcoming the stopper piece 7 of the seedling placing portion Ba, and after this operation is completed, the first air cylinder AC1 is restored and operated. As a result, as shown in FIG. 6C, the seedling-containing carrier A is pulled out, and further, the engagement piece 23 is disengaged by the restoring operation of the second air cylinder AC2, so that the seedling-containing carrier A is laterally fed. D conveyor It becomes to be placed on the belt 10. A take-out section is constituted by a system for taking out the seedling-containing carrier A together with the engaging piece 23.

Next, the conveyor belt 10 of the transverse feed mechanism D is driven by the drive of the first electric motor M1 to feed the seedling-containing carrier A toward the turntable E, and at the same time, the horizontal feed mechanism D is moved up and down to convey the conveyor. Level setting control is performed to match the level of the belt 10 with the level of the carry-out conveyor Eb of the turntable E (the level that matches the level of the conveyor mechanism F). In addition, during the operation of feeding the seedling-containing carrier A by the horizontal feeding mechanism D as described above, or prior to the feeding operation, the turntable E is rotated around the longitudinal axis Y (FIG. 9A). As shown in FIG. 3, the retracting frame 36 is moved to the side of the lateral feed mechanism D in a state where the carrier A for receiving seedlings is set in the posture and the claw 37 of the retracting mechanism Ea is set in the open position. Then, when the proximity sensor S of the lateral feed mechanism D detects the seedling-containing carrier A, the conveyor belt 10 is temporarily stopped, and thereafter, the conveyor belt 10 is driven to drive the proximity sensor S of the drawing frame 36.
When the carrier A containing seedlings is detected, the fourth air cylinder A
By driving C4, as shown in FIG.
7 is engaged and the conveyor belt 10 is stopped. After that, the seedling-containing carrier A is drawn into the carry-out conveyor Eb together with the drawing frame 36 by the operation of the third air cylinder AC3, and the claw 37 is opened. When the feeding direction of the carry-out conveyor Eb and the feeding direction of the conveyor mechanism F coincide with each other at the time of pulling in, the seedling-containing carrier A is sent to the conveyor mechanism F by driving the carry-out conveyor Eb. Further, when the feeding direction of the carry-out conveyor Eb is different from the feeding direction of the upper conveyor 44 of the conveyor mechanism F when the carrier A containing seedlings is drawn in, the carry-out conveyor Eb is rotated by rotating the turntable E around the longitudinal axis Y. After making the feeding direction of the seedlings coincide with the feeding direction of the conveyor mechanism F, the seedling-containing carrier A is sent to the conveyor mechanism F by driving the carry-out conveyor Eb, and the seedling-containing carrier A thus sent to the conveyor mechanism F.
Is sent to the spare seedling storage section J via the seedling supply section L of the rice transplanter by the upper conveyor 44.

Simultaneously with the seedling replenishment, the empty carrier A in the spare seedling storage section J is controlled to be sent to the seedling replenishing device by the lower conveyor 45 of the conveyor mechanism F. This control will be described in detail below.

When the empty carrier A is sent by the lower conveyor 45 of the conveyor mechanism F, the turntable E is set in the receiving posture by the rotation around the longitudinal axis Y, and the carry-in conveyor Ec sets the empty carrier A to the stopper 42. Send it to the position where it touches. Next, when the empty carrier A reaches this position, as shown in FIG. 12, the endless rotation chain 50 is driven and the chuck claws 51 of the stacking mechanism G are moved to the empty carrier A.
The vertical wall is chucked A, and at the same time, the stopper 42 is retracted to feed the empty carrier A to the stacking position. When reaching this position, the proximity sensor detects the chuck claw 51, the sixth air cylinder AC6 forcibly opens the chuck claw 51, and the empty carrier A drops onto the elevating table 54. After this drop supply, the elevating table 64 descends by the thickness of the carrier A. Further, when four empty carriers are stacked by this drop supply, the elevating table 54 is lowered to the lowermost end, and the four empty carriers A in the stacked state are collectively stored in a rack by the operation of the pusher 56. It is sent into the space below part B. In this space, four empty carriers A stacked
Are continuously sent, and the worker artificially takes out the empty carrier A from this space.

Further, at the time of replenishing the seedlings, fertilizer from the fertilizer tank 61 provided in the bed of the truck 1 is sent into the hose 62 by compressed air, and the hopper of the fertilizer application mechanism 70 of the rice transplanter is passed through the inside of the connecting member 46. 70A is automatically replenished (control operation is not described in detail).

As described above, according to the present invention, when the seedling-containing carrier A is sent from the seedling replenishing device to the rice transplanter, the seedling-containing carrier is sent through the upper conveyor 44 as the first conveying section of the conveyor mechanism F. When the empty carrier is collected from the empty carrier A, the empty carrier A can be collected through the lower conveyor 45 serving as the second transport unit. That is, the upper conveyor 44
And the lower conveyor 45 can be used at the same time for quick work, and the collected empty carriers can be automatically stacked to improve the handling, and the stacked empty carriers can be stored in a small space. Has become.
