Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transplanter for transferring a band-shaped seedling by a carrier device, cutting the seedling into a predetermined number of seedlings by a cutting device, and planting the seedling in a field.

[0002]

2. Description of the Related Art Strawberry seedlings or other seedlings are continuously attached to a tape in advance, knitted in a filament form so as not to be separated, or simply pressed to spread the seedlings flat. Has been studied to form banded seedlings suitable for mechanical planting, and to plant seedlings in the field using the banded seedlings. As a transplanter used for this planting, the belt-shaped seedlings are transferred by a transport device, and at the end of the transport, a cutting device cuts the seedlings into a predetermined number of seedlings. A method of scraping and planting in a field has been developed by the present applicant. Moreover, as the cutting device, an actual flat blade 4-10
As known from Japanese Patent No. 0306, etc., a cutting mechanism and a receiving blade are reciprocally moved to the left and right in opposite directions by a drive mechanism, and the cutting blade is supported by the cutting blade while supporting the root part of the band-shaped seedling on the receiving blade. A method of cutting into a predetermined number of planted seedlings is adopted. Incidentally, in the above-mentioned published specification, with one of the blades being fixed at a position supporting the root part of the band-shaped seedling, a device for cutting the band-shaped seedling by reciprocating only the other cutting blade left and right. Is also disclosed.

[0003]

In a transplanter for scraping a band-shaped seedling with a planting claw and planting it in a field, the above-mentioned cutting device is provided for cutting a predetermined number of planted seedlings from a subsequent band-shaped seedling. It is an indispensable device. However, the conventional cutting device that reciprocates the cutting blade and the receiving body in the left and right directions by the drive mechanism sometimes causes a mistake in cutting the band-shaped seedlings. It interferes with the scraping of seedlings, resulting in a missing plant. When the cause is investigated, a cutting error occurs when the cutting blade shakes the strip-shaped seedling largely left and right, and when the cutting blade divides into the strip-shaped seedling and shakes the strip-shaped seedling largely, the plant base part shifts toward the stem body. As a result of the stock base part coming off from the cutting action width of the cutting blade,
A cutting error occurs. However, the blades provided on the other side of the cutting blade are originally provided to support the root part of the band-shaped seedling from the other side and prevent the position of the root part from shifting when the cutting blade cuts the band-shaped seedling. . Therefore, it is presumed that there is a problem on the side of the blade that the cutting error occurs even if the blade is provided.

Therefore, when the receiving blade side is verified, in the conventional receiving blade, after the cutting blade is divided into the band-shaped seedlings, the receiving blade is also adjusted to the timing of the full stroke movement of the cutting blade to complete the cutting. It is synchronized so that it will move a full stroke to a position that supports the stock section. Therefore, when the cutting blade splits into the band-shaped seedling and starts cutting, the blade receiver has not yet reached the proper position to support the root of the band-shaped seedling, and the band-shaped seedling is unsupported after all. In this state, the cutting action of the cutting blade is greatly shaken by the receiving blade side, and the cutting error deviates from the cutting action width of the cutting blade to cause a cutting error. Therefore, as in the latter cutting device of the above-mentioned specification, even if the cutting blade is fixed and the cutting blade is reciprocally moved to the left and right, and the cutting blade is divided into strip seedlings and is shaken, The body is configured to always support the root part of the banded seedling to eliminate the position deviation of the root part,
It is conceivable to prevent a cutting error.
However, if the blade is always exposed to the transfer passage, the blade acts as a transfer resistance for the band-shaped seedlings, disturbing the transporting posture of the band-shaped seedlings, and rather causes more cutting errors. In addition, there is a concern that the planting claw may come into contact with the blades facing the scraping locus due to improper installation of the planting claw or the left and right swings of the planting claw, and may damage each other, There is a problem that the adoption of such a structure must be abandoned.

[0005]

In order to solve the above-mentioned conventional problems, the present invention cuts a band-shaped seedling transferred by a transfer device into a predetermined number of planted seedlings with a cutting blade and a blade. In a transplanting machine for planting this cut planted seedling in a field with a planting nail,
The action in which the cutting blade and the blade are attached to the left and right operation arms, respectively, and the left and right operation arms are driven by the drive mechanism so that one of the blades retreats from the transfer passage supports the root portion of the band-shaped seedling in the transfer passage. After moving to the position, the other cutting blade is synchronized so as to divide into the root part of the band-shaped seedling, and is configured to reciprocate in the left-right opposite directions. Further, when the blade actuating arm drive mechanism described above is moved to the position where the blade supports the root part of the band-shaped seedling in the transfer passage, the cutting blade is stopped and held at that position until the cutting blade cuts the root part. To configure.

[0006]

The strip-shaped seedlings transferred by the transfer device are cut into a predetermined number of seedlings by a cutting blade and a blade at the end of the transfer device. Then, the cut planting seedlings are temporarily locked by the guide, and the planting claws are caught immediately after the plant base of the planting seedlings that is locked, scraped off, and planted in the field. In this cutting process, the cutting blade attached to the actuating arm and the receiving blade reciprocate in the left-right direction by the drive mechanism, and when the band-shaped seedling is transferred, the receiving blade moves from the position retracted from the transfer path to the transfer path. Move to the working position that supports the root part of the banded seedlings. Then, when the movement of the blade body to the working position is completed,
At about the same time, the cutting blade splits into the root part of the band-shaped seedling to start cutting, and further moves by a full stroke to complete cutting.
Further, the actuation arm drive mechanism of the blade receiving body, when the blade receiving body moves to the working position supporting the root part of the band-shaped seedling in the transfer passage,
The blade receiver is stopped and held at that position until the cutting blade cuts the root portion of the plant, and the blade base is regulated by the blade member until the cutting is completely completed.

At the same time, the planting claw 102 of the planting apparatus D descends, the planting beak 100 captures the plant root of the planted seedling n, and scratches the planted seedling n from the elastic guide bodies 43, 44, 45, 46. take. Then, the planted seedling n scraped off reaches the field scene, is extruded by the extrusion fork 101, and is planted in the field.

Here, the cutting device C comprises a cutting blade 60 and a receiving blade 63, and when the band-shaped seedling N is sent out by the seedling sending-out device B, the cutting blade 60 and the receiving blade 63 are moved to the transfer passage shown in FIG. From the retracted position where R is opened, the drive shafts 68 and 69 are rotated in the opposite directions by the roller 83 and the closing driven cam 87 provided in the knife case 67, and the cutting blade 6
0 starts moving counterclockwise around the cutting blade drive shaft 68, and the blade receiving body 63 starts moving clockwise around the pivot pin 71. Then, as shown in FIG. 5, the blade portion 6 of the blade body 63.
When the tips of the blades 1, 62 reach the working position for supporting the root portion (tape adhering portion) of the band-shaped seedling N, the cutting blades 60 on the other side are almost simultaneously produced
Pierces the sharp edge of the tape T on the strip-shaped seedling N and starts cutting. Further, the cutting blade 60 is divided into the root part of the seedling as shown in FIG. 6 and moved by a full stroke to complete the cutting. Upon completion of cutting, the opening drive cam 85 provided inside the knife case 67 contacts the opening driven cam 88, and the cutting blade drive shaft 68 and the blade receiving body drive shaft 69.
Is rotated in the opposite direction to the above-mentioned direction, and the cutting blade 60 and the blade receiver 63 are returned to the retracted position where the transfer passage R before the cutting is opened is opened.

More specifically, in the above cutting process, the rotation angle of the blade receiving drive shaft 69 is relative to the rotation angle of the cutting blade drive shaft 68 in the knife case 67 in the arm ratio l of the driven cam 87. It is regulated to about 1/2 by L (in the embodiment, the rotation angle of the blade receiving body drive shaft 69 is set to 22).
And the rotation angle of the cutting blade drive shaft 68 is set to 40 degrees).
Further, outside the case, the rotation angle of the actuating arm 66 of the blade receiving member 63 is regulated by the cam plate 72 and the roller 73 to about 1/2 of the rotation angle of the blade receiving member drive shaft 69.
Therefore, the rotation angle of the operating arm 66 of the blade receiver 63 is limited to a small angle of about 1/4 of the rotation angle of the operating arm 64 of the cutting blade 60. Therefore, the blade 63 moves from a position retracted from the transfer passage to a working position that supports the root part of the band-shaped seedling N without making a drastic change in position, at a minimum not causing transfer resistance of the band-shaped seedling, and Even if the cutting blade 60 on the side tries to shake the strip-shaped seedling by abutting against the strip-shaped seedling N, the blade 63 surely supports the root part of the strip-shaped seedling N at that time and shifts the position of the root part. Support it so that it does not occur. Therefore, the cutting blade 60 contacts the root part of the band-shaped seedling N first while the receiving blade 63 does not support the root part as in the conventional case.
There is no need to shake the unsupported band-shaped seedling largely to cause cutting failure, and complete cutting is performed with the root part firmly supported by the blade 63 from the beginning of cutting.

A cam plate 7 for driving the operating arm 66
2, the cam surface 72a is formed by a first half cam surface c radially extending from the blade receiving body drive shaft 69 and a second half cam surface d having the same radius from the blade receiving body drive shaft 69, and the intersection thereof is formed. It is set so that the tips of the blade receiving portions 61, 62 of the blade receiving member 63 come to an operating position for supporting the root portion of the band-shaped seedling N. Therefore, when the tip ends of the blade receiving portions 61, 62 reach the operating position for supporting the root portion of the band-shaped seedling N, the blade receiver 63 stops at the operating position until the cutting blade 60 cuts the root portion. Therefore, even if the blade receiving member 63 is moved to the operating position earlier than the conventional blade receiving member as in the present invention, the blade receiving member 63 is stopped after that, so that the blade receiving member 63 is The cutting seedlings and the subsequent strip-shaped seedlings are further swung to the other side of the transfer passage by moving the cutting seedlings 60 to the cutting blade 60 side from an appropriate working position supporting the parts. It does not cause a defect that a scraping error occurs by separating from the scraping locus, and does not cause a problem that mutual damage is caused by interfering with the planting claw 102. Although the above-mentioned cam plate 72 is externally attached to the knife case 67 in the embodiment, it may be internally provided in the knife case 67, and the drive mechanism for the cutting blade 60 and the blade receiving member 63 is input in the same manner. The cutting blade 60 and the blade receiver 6 may be used as long as they are synchronized with each other as a source.
The reciprocating mechanisms of 3 may be modified such that they are independently driven by separate cam mechanisms.

[0018]

According to the present invention, the cutting blade and the blade are attached to the left and right operating arms respectively, and the left and right operating arms are retracted from the transfer passage by the drive mechanism. When the cutting blade moves to the position where it supports the root of the seedling, the other cutting blade is synchronized with the root of the seedling so that it reciprocates in the opposite directions. When cutting into the root part of the banded seedling to start cutting, the blade always supports the root part at the same time from the other side and does not cause displacement of the root part, thus preventing cutting mistakes. Good planting can always be done. Further, the actuating arm drive mechanism of the blade receiving body moves the blade receiving body to that position until the cutting blade cuts the plant base portion when the blade receiving body moves to an operating position that supports the plant base portion of the band-shaped seedling in the transfer passage. Since it is configured to stop and hold, it does not shake the cut planting seedlings and the subsequent strip-shaped seedlings reversely by the blade, and it is possible to prevent problems such as inducing scraping mistakes of the planting nails. it can.
