Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling transplant provided with a seedling fall prevention device for preventing contact of a seedling planting tool with a driving portion due to a fall of a seedling immediately after planting. The present invention relates to a seedling planting section of a machine, and more particularly to improvement of a seedling fall prevention device. 2. Description of the Related Art Conventionally, a whole seedling fall prevention device is fixedly arranged on a driving portion side of a seedling planting tool from a seedling planting position, and unless a seedling immediately after planting largely falls down on the driving portion side, the seedling falls. The preventive device was configured not to contact the planted seedling. [0003] However, since the seedling immediately after planting is almost in an upright state, the mud that has been flipped up toward the rear of the machine by the planting claw of the seedling planting tool is placed on the seedling immediately after planting. There is a possibility that seedlings may be poorly grown due to the mud, which is likely to fall, and there is room for improvement from the viewpoint of preventing the mud from adhering to the seedlings. [0004] It is an object of the present invention to prevent the mud, which has been jumped up toward the rear of the machine with the planting claws, from adhering to the seedling immediately after planting. [0005] A characteristic feature of the present invention is a seedling.
Place the planting tools on the lateral outside of the drive unit and plant seedlings.
The seedling immediately after being planted with the tool falls down to the drive section side
To prevent contact with the drive unit.
In the seedling transplanter, the planting is re-
Seedling for tilting the rear seedling away from the drive unit
A pressing portion is provided on the seedling fall prevention device. [0006] In other words, the seedling immediately after planting is separated from the drive unit of the seedling planting tool by the pressing action of the seedling pressing unit as the aircraft advances.
Since tilting to the side, in a state deviated from scattered locus of mud thrown up toward the body backward planting claw can be positioned seedlings immediately after planting, the seedlings in the mud thrown up by the planting claw Adhesion is sufficiently suppressed, and poor growth of seedlings caused by the attached mud can be effectively prevented. As a result, it has become possible to provide a seedling transplanter that is less likely to adhere to the seedlings immediately after planting, and that is more excellent in terms of growing seedlings, as mud that has been flipped up by the planting claws. [0008] As shown in Fig. 1, a seedling planting device 2 is connected to a riding transplanter main body 1 by a link device 3 so as to be able to move up and down freely, intermittently laterally moved and reciprocated left and right at a constant stroke. Seedling mounting table 4 to be taken, seedling planting tool 5 for taking out seedlings of one strain from the lower end of seedling mounting table 4 and planting them, seedling planting apparatus 2
The seedling planting apparatus 2 is provided with a ground float 6 or the like, which supports the planting and leveling of the planting ground, to constitute a seedling transplanter for rush. A belt conveyor type vertical feeding device 7 for taking out seedlings by a certain distance each time the seedling placing table 4 reaches the stroke end of the left-right movement on the seedling placing table 4, and feeding the seedlings to the opening side;
A seedling pusher 9 is provided for taking out the seedlings by its own weight descending along the guide rails 8 and sending them to the mouth side. As shown in FIG. 2 and FIG.
To form a planting nail 10 for removing and planting a seedling
At the time of planting, the seedling pusher 11 for pushing out the seedlings held by the planting claws 10 is attached to the planting arm 12, and at the time of taking out the seedlings, the seedlings on the seedling placing table 4 are located near the upper part of the seedlings on the seedling mounting table 4 before the planting claws 10. Auxiliary claws 13 are provided to enter and facilitate seedling separation. A seedling fall prevention device 15 for preventing contact of the seedling planting device 5 with the drive unit 14 due to the lateral fall of the seedling immediately after planting.
And a plate-like stem tipping prevention portion 15a fixed to the main body of the seedling planting device 2, and a diameter of 3 for tilting the seedling immediately after planting to the opposite side to the driving portion 14 by a pressing action accompanying the progress of the body.
It is formed by a rod-shaped seedling pressing portion 15b of about mm to 3.5 mm. The tip fall prevention portion 15a is disposed closer to the drive portion 14 than the seedling planting position, and the tip fall prevention portion 15a does not come into contact with the planted seedling unless the seedling immediately after planting largely falls down to the drive portion 14 side. It is configured as follows. The seedling pressing portion 15b is formed by a piano wire whose front end is cantilevered by a tip falling prevention portion 15a.
Is disposed about 30 mm to 60 mm above the bottom surface of the ground float 6, and the front working portion 15 ba is gently inclined with respect to the body traveling direction so as to be more laterally away from the drive unit 14 toward the rear, and the rear working portion The seedlings 15bb can be displaced toward the drive section 14 against the elastic restoring force while being directed to the body traveling direction, and as shown in FIG. At an angle of about 15 to 20 degrees to the opposite side of the drive unit 14 to prevent contact between the seedling immediately after planting and the planting arm 12, and immediately after planting the mud that has been flipped up toward the rear of the machine by the planting claw 10. The method is intended to suppress the adhesion to the seedlings and realize the orderly seedling planting with a constant planting posture. [Another Embodiment] The specific configuration of the drive unit 14 of the seedling inoculation tool 5 can be appropriately changed. In forming the seedling fall prevention device 15, the stem tip fall prevention portion 15a may be omitted. The seedling pressing portion 15b can be appropriately changed in shape, material, mounting structure, and the like. The seedling transplanter according to the present invention may be for a rice plant or the like. In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the attached drawings.
