Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for dividing a mother plant using a rush transplanting machine that divides and plants the mother plant.

When dividing a rush mother plant into a size suitable for transplanting, it is not possible to divide the mother plant by inserting the plant from the top of the mother plant, as in the well-known rice transplanter. ) bonds are much stronger than in rice seedlings, so a great deal of force is required to split them, damaging the new shoots that are forming at the root edge of the mother plant, often inhibiting growth after transplanting, and hindering mechanization. It is becoming.

Therefore, the present invention provides a rush transplanting machine having a configuration similar to a well-known rice transplanting machine, that is, a seedling platform on which a rush mother plant is placed and which moves back and forth in the left-right direction of the machine body with a predetermined stroke, A seedling receiving part is fixed to the machine body facing the end of the stand and has a seedling take-out port.It reciprocates vertically in a predetermined trajectory, and divides the mother plant from the seedling take-out port and takes it out to the field. In a transplanter equipped with a seedling planting body for planting, pierce the bottom of the mother plant from below the seedling take-out opening with a receiving claw,
The purpose of the present invention is to provide a method for dividing plants in a rush transplanter which solves the above problem by dividing the plants by the seedling planting body in synchronization with the piercing operation of the receiving claws.

Embodiments of the present invention will be specifically described below with reference to the drawings.

In the figure, reference numeral 1 is a transmission case that also serves as a frame provided in the planting part of the rush transplanter, and a handle rod 2 has one end fixed to the rear of the case 1 and the other end extending diagonally upward to the rear of the machine. is established,
A seedling stand 3 is supported on the front side of the handle rod 2 by the transmission case 1 and the handle rod 2 so as to reciprocate along the slope of the handle rod 2 and at a predetermined interval in the left-right direction. A seedling receiving part 4 fixed to the transmission case 1 side is provided at the inclined lower end of the seedling mounting table 3, and a seedling taking out port 5 is opened in the seedling receiving part 4. In addition, the transmission case 1, which is opposite to the seedling take-out port 5, is provided with seedlings that pass through the seedling take-out port 5, reciprocate while drawing a predetermined trajectory 7 in the vertical direction, take out the seedlings in the form of a single plant, and plant the seedlings on the rice field. A planting body 6 is arranged. Each of these mechanisms is similar to a well-known rice transplanter, and in this embodiment, it is applied to a walking-type rush transplanter.

The seedling platform 3 has an open top surface and an upper end,
A seedling feeding mechanism 8 consisting of an endless band on the upper part, a seedling mounting plate 9 provided continuously with the end of the seedling feeding mechanism 8, and a hole 9a drilled in the seedling mounting plate 9 to lower the mother plant. It has a seedling feeding claw 10 and side frames 11 erected in the front-rear direction on both sides of the seedling feeding mechanism 8 and the seedling mounting plate 9. In addition, on the transmission case 1 side, the mother plant at the lower end of the seedling mounting plate 9 is placed from above.
A seedling feeding needle 12 is provided that rakes the seedlings downward.

Further, as shown in detail in FIG. 2, the seedling planting body 6 includes a fixed claw 13 and a movable claw 14, and displaces the movable claw 14 during the movement process along the trajectory 7, and when taking out the seedlings. Fixing claw 1 as shown by the imaginary line
3 and becomes a fixed claw 13 and a single sharp claw, and when planting seedlings on the rice field, they move forward from the fixed claw 13 as shown by solid lines and plant the seedlings on the rice field. This fixed claw 13 and movable claw 1
4 is composed of a pair of parts each having a predetermined interval on the left and right sides.

As shown in FIG. 3, the seedling receiving part 4 has a pair of endless bands 15, 15 on the left and right sides of the seedling take-out opening 5.
has been established. This endless belt 15 is constructed by winding a belt 16 around a pair of pulleys 17 so that its surface intersects with the seedling mounting plate 9, as shown in FIG. The pulley 17 is made to be rotatable while facing the side surface of the root part, and the surface of the belt 16 is fixed to the side frame 11 of the seedling platform 3, so that the belt 16 is moved in the same direction as the seedling platform 3 moves. It was designed to do so. Furthermore, a receiving claw 18 that operates in synchronization with the seedling planting body 6 is provided at the bottom of the seedling take-out port 5 . This receiving claw 18
As shown in FIG. , the movable rod 19 moves upward to project the receiving claw 18 into the seedling take-out port 5, and the receiving claw 18 pierces the bottom of the weed transfer, and in synchronization with this stabbing action, the seedling planting body is It descends to divide the seedlings, and as the seedling planting body 6 descends, the receiving claws 18 also descend. Further, the seedling feeding mechanism 8, the seedling feeding claw 10, and the seedling feeding needle 12 are also operated at regular intervals in conjunction with the operation of the seedling planting body 6 and the receiving claw 18.

In a rush transplanting machine having such a configuration, when performing transplanting work, a large number of rush mother plants are loaded one after another on the seedling platform 3, and the planting section is driven as the machine moves. The seedling planting body 6, which moves up and down in a trajectory 7, has its movable claw 14 integrated with the fixed claw 13 as shown by the imaginary line in FIG. 2, and pierces the mother plant from above. In synchronization with this, the receiving claws 18 are pierced upward from the bottom of the mother plant, so the mother plant receives shearing force, and even the strongly connected roots are easily split into single plants, and the seedlings are planted. 6
The catch jaw 1 moves in conjunction with this descent.
8 also descends. When the tip of the seedling planting body 6 is inserted into the rice field, the movable claw 14 projects below the fixed claw 13 as shown by the solid line in FIG. 2, the seedlings are planted on the rice field, and the seedling planting body 6 rises. , repeat the same operation as above again to plant the seedlings.

On the other hand, the seedling platform 3 sequentially sends the mother plants to the seedling take-out port 5 while reciprocating with a constant stroke, and the seedling feeding mechanism 8 sequentially lowers the mother plants and sends them onto the seedling platform 9, so that the seedlings The feeding claw 10 is the seedling mounting board 9
The upper mother plant is lowered, and the mother plant is further drawn to the seedling receiving part 4 with the seedling feeding needle 12. And the seedling receiving part 4
The mother plant located at 1 has its lower end in contact with the belt 16 of the endless belt 15, and as the belt 16 moves in synchronization with the movement of the seedling platform 3, it maintains the correct posture sent from the seedling platform 19. The seedlings, which are sent to the seedling take-out port 5 and taken out by the seedling planting body 6, are planted in the rice field in the correct posture without damaging the stems or shoots, resulting in good results for subsequent rooting and growth.
In addition, in this example, the division of the mother plant is performed using the seedling planting body 6.
Since this is done with the receiving claws 18 that operate in synchronization with this, there is no problem even if the strength of the seedling planting body 6 is weaker (thinner) than that without the receiving claws 18.

As explained above, according to the present invention, when the mother plant of grass placed on the seedling platform is taken out from the seedling take-out port by the seedling planting body, the bottom part of the mother plant is inserted into the catch from the lower side of the seedling take-out port. Since the seedling planting body is used to divide the plants in synchronization with this stabbing action, even mother plants with strong roots, such as rushes, can be divided reliably with a small amount of force. Therefore, the seedlings are not damaged, and the strength of the seedling-planting body can be made weaker, thinner, and sharper than conventional ones without any problem.
