Abstract

PURPOSE:To dissolve the blockade of the gaps between the nails with the seedling roots, as the action to divide seedling stocks is kept well with the tip- notched nails, by providing a part for removing the root of the seedling which is nipped between nail notches constituting the separation mechanism. CONSTITUTION:Separation nail 25 is composed of a pair of nails 25a and 25b which are arranged along the direction crossing the direction to which the mother stock M is sent and the tearing action by the nails resembles the shearing action to effect reasonable stock division. Further, the arm 45 is set to the frame D rotatably around the pivot and the remover 44 of a bar which can come into the notched parts 25c is attached to the tip of the arm 45. Thus, when the separation nail 25 reciprocates back and forth, the remover 44 moves in the notched parts 25c as it is reciprocating to develop the scraping action whereby the roots or the soil blocking the notched parts are excluded. As a result, the pitch of the nail into the roots is kept at a prescribed value and good stock-dividing action is performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crop seedling stock splitting machine for splitting a densely grown mother stock such as straw grass seedlings into small stocks suitable for transplantation into a field.

[0002]

2. Description of the Related Art As a stock dividing machine for strawberries, in Japanese Patent Application No. 4-125206 filed by the applicant of the present application, a pair of belts are arranged so that their facing intervals are narrowed to form a mother stock. A transporting device for transporting while applying a crushing deformation force, and a separator for thrusting the split claws into the root of the mother plant transported by the transporting device and forcibly separating into small plants A stock splitting machine has been proposed.

[0003]

According to this, although it has the advantage of being able to divide each strain into almost one strain without difficulty, if the bifurcated separating claw is continuously moved back and forth to the root, The separated root part may be caught between the nails and clogged, which may hinder a good stock-splitting action. An object of the present invention is to eliminate the clogging phenomenon in the gap between the nails while making good use of the good stock-splitting effect of the claw-shaped nail body.

[0004]

In order to achieve the above-mentioned object, the present invention constitutes a carrying device for sandwiching and carrying crop seedlings by disposing a pair of endless rotation bands facing each other, and the carrying device carries the crop seedlings. In order to flatten and deform the mother plant of the crop seedling, the facing interval of the pair of endless rotation bands is made narrower toward the lower side of the mother plant transport direction, and the crushed and deformed crop seedling at the transport end of the carrier device is used. Equipped with a separating device that works to forcibly separate into small plants, this separating device is used to continuously enter and retract the claw body with a notch with a notch and the root part of the crop seedling of this claw body. It is characterized by comprising a removing mechanism capable of eliminating the root part of the crop seedling sandwiched in the notch while being configured with a driving mechanism.

[0005]

[Function] In other words, the removal member can eliminate the root part sandwiched in the notch of the claw body, so the clogging phenomenon of the notch is eliminated, and the clogged root part becomes a resistance, and the amount of penetration of the claw body into the root part is expected. It will not be impossible to pass by, and it will be possible to always exert a good stock splitting effect.

[0006]

Therefore, by a relatively simple modification by providing a removing member for the notch of the claw body, a crushing and deforming action by the conveying device and a reliable separating action without damage to the root part due to the withdrawal movement of the claw body. It was possible to provide an excellent stock-splitting machine that splits stocks into small stocks in a highly reliable state in which the good stock-splitting state can be continuously maintained.

[0007]
