Abstract

PROBLEM TO BE SOLVED: To provide the subject seedling-transplanting apparatus capable of being produced without increasing the number of components, and improving attaching operability by detachably attaching a soil-removing bar on a transplanting body, etc., so that a soil-removing fragment may protrude to a portion between both pushing out fragments in a seedling-pushing out tool. SOLUTION: This seedling-transplanting apparatus has a transplanting tine 2 having both chopstick-like bodies 2c and 2d having shapes extending from a base part 2a connected by a bolt 3 to a transplanting lever, and formed by cast, a soil-removing bar 6 detachably attached to a transplanting body 1 or the transplanting tine 2 and extending between both chopstick-like bodies 2c and 2d in the transplanting tine 2 toward the tip part so that the soil-removing fragment 6a detachably installed in the tip of the soil-releasing bar 6 may protrude through the position between the both chopstick-like bodies 2c and 2d to the portion between both pushing out fragments 5a and 5b in a seedling- pushing out tool 5. The base terminal part 2a in the transplanting line 2 is formed into a thickened state thicker than the both chopstick-like bodies 2c and 2d, and weight-reducing concave part 2e is preferably formed at the back surface of the base terminal part 2a.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a planting claw for taking out a seedling from a seedling mounting table and planting a seedling in a field scene, comprising two chopsticks arranged in parallel. The present invention relates to a seedling plant apparatus comprising:

[0002]

2. Description of the Related Art Conventionally, in a seedling planting apparatus comprising two chopsticks in which planting claws are arranged in parallel, a pair of left and right extruded pieces are provided on the back side of the two chopsticks. The seedling extruder is provided so as to reciprocate along both chopsticks, and the seedlings taken out of the seedling table with the two chopsticks are moved toward the tips of the two chopsticks in the seedling extruder. It is configured to be pushed into the field scene by the forward movement of.

[0003]

In the conventional seedling plant thus constructed, the seedlings taken out of the seedling mounting table with two chopstick-like planting claws are provided on the rear side of the planting claws. Since the seedlings are pushed into the field scene by the seedling pushing tool, there is an advantage that the seedlings can be planted in the field scene reliably in a correct posture.

However, on the other hand, the seedling extruder is
By entering the field each time a seedling is planted in the field scene, mud will adhere to the seedling extruder. Not only does this change, but there is a problem that the seedling pushing tool cannot push the seedlings.

Further, in the conventional seedling planting apparatus, the planting claws are composed of two chopsticks. However, since the two chopsticks have to be separately forged, they are manufactured. Not only does this significantly increase the cost of installation, but also requires additional parts to mount the two chopsticks side by side in parallel, so the number of parts required for installation increases, There was also a problem that the sex was low.

An object of the present invention is to provide a seedling-planting apparatus which has solved these problems.

[0007]

In order to achieve the above technical object, the present invention provides a method in which planting claws removably attached to a planting body which moves down and then moves up toward a field scene are arranged in parallel. A seedling plant comprising two chopsticks, and a seedling extruder having a pair of extruded pieces provided on the back side of the planting nail so as to reciprocate along both chopsticks. In the above, the planting claw is formed by casting in a form in which both chopsticks are integrally extended from a base end portion which is bolted to the planting rod. A mud-dropping rod extending toward the tip between both chopsticks is formed by moving a mud-dropping piece provided at the tip of the mud-dropping rod between the two chopsticks and between the two pushing-out pieces in the seedling extruding tool. Attach it detachably so as to protrude at the part. It was constructed to say.

[0008]

Operation and effect of the present invention
Each time the seedling pushing tool repeats the forward and backward movements of the planting claw in the tip direction, the mud-dropping rod protruding rearward from between the two extruded pieces between the two chopsticks at the planting claw. Since the sludge pieces at the tip end pass through, the mud adhering to the seedling extruder can be scraped off.

Therefore, according to the present invention, the adhesion of mud to the seedling extruder can be greatly reduced, so that the change of the planting posture of the seedling caused by the adhesion of the mud to the seedling extruder and the change of the seedling can be achieved. It is possible to reliably prevent inability to extrude, etc.Moreover, since the mud-dropping rod is detachably attached to the planting body or the planting claw, the mud-dropping rod can be used as a separate component from the planting claw. Can be replaced with
The planting claw can be manufactured at low cost by casting, and has an effect that the attachment to the planting body can be extremely easily performed by the bolt at the base end without increasing the number of components.

[0010] Further, as described in claim 2, the base end of the planting claw is made thicker than both chopsticks, and a meat stealing recess is provided on the back surface of the base end. Accordingly, there is an advantage that the rigidity of the planting nail can be significantly improved without increasing the weight of the planting nail. Furthermore, as described in “Claim 3”,
By providing an engaging portion in which the middle part of the mud-dropping bar is fitted and engaged, the mud-dropping bar can be displaced without the mud-off piece at the tip thereof being displaced in the lateral direction.
Since the mud-dropping pieces can be automatically positioned so as to be always located between the both extruded pieces in the seedling extruder,
Since the attachment of the mud-off rod can be easily performed, and the mud-off rod can be held so that the mud-off piece at the tip thereof does not bend and deform in the lateral direction.
There is an advantage that it is possible to reliably reduce the possibility that the tip of the mud dropping bar interferes with the seedling pushing tool due to the bending deformation of the mud dropping bar.
