Abstract

PURPOSE:To enable sure insertion of a leaf and stalk of a seedling into a notched groove in the case of seedling division and to enable the holding of divided seedling from a seedling table in an accurate posture, by widening the lateral width of an upper part of a notched groove formed on a front side plate of a seedling division transplantation claw. CONSTITUTION:A seedling division transplantation claw 8 is composed of the right and left side plate parts 8a, 8a and a front side plate 8b which together form a U-shape when viewed from above. The lateral width is narrowed at the lower side when viewed from the front side forming an inverted V-shape at the lower end. When viewed from a side, the lower part of the claw is diverged and the bottom is formed of a face 8c incline from the front side toward the rear part and of an elevated part 8d connected with the inclined face. The front side plate is provided with a notched groove 9 to enable the passage of the leaf and stalk part of a seedling in the seedling division from the lower V-shaped apex upward. The upper part of the notched groove has widened lateral width. Even a leaf and stalk part expanded to open the leaves can be released to the front side of the seedling transplantation division claw without damaging the seedling.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a seedling transplanting device in a rice transplanter.

BACKGROUND ART Conventionally, there has been a seedling transplanting device for a rice transplanter as disclosed in Japanese Utility Model Application Publication No. 55-37386. That is, in this conventional seedling dividing nail for transplantation, the width of the notch groove formed at the left and right center of the front side plate is narrow and constant.

Problems to be Solved by the Invention In the conventional seedling dividing claws, the upper side of the leaves and stems of the seedlings cannot intervene in the notch grooves formed at the left and right center of the front side of the claws when dividing the seedlings. The leaves and stems of the plants tend to fall backwards and are not held correctly, causing them to fall unexpectedly while being transferred to the soil below, and the plants cannot be transplanted in an upright position.

Technical Means for Solving the Problems In order to solve the above-mentioned problems, the present invention divides and holds the seedlings fed out against the seedling feeding side of the seedling platform 1 and transplants them to the soil surface below. The seedling dividing transplanting nails 8 of the seedling transplanting tool 5 are attached to the left and right side plate portions 8a.

8a and the front plate part 8b are U-shaped in plan view, the left and right width of the lower side becomes narrow in front view, and the lower end is V-shaped, and in side view, the lower part widens toward the end, and the lower end extends from the front side to the rear. It is formed into an inclined slope 8C and a continuation mountain shape 8d,
A notch groove 9 is formed in the front side plate part 8b upward from the apex of the V-shaped part at the lower end through which the leaves of the seedling can pass when dividing the seedling, and the left and right width of the upper part of this notch groove 9 is formed to be wide. This is a seedling transplanting device for a rice transplanter.

Functions and Effects of the Invention According to this invention, when dividing seedlings, the leaves and stems of the seedlings can be reliably inserted into the notch grooves formed on the front side of the seedling dividing claws, and the seedlings can be placed in an accurate posture and removed from the white side. It can be kept divided and transplanted reliably.

Example 1 is a seedling stand, which has a bottom plate 1a and left and right side plates 1b.

1b is formed into a rectangular shape that is long in the front-rear direction when viewed from above. Reference numeral 2 denotes a seedling receiving frame, which has a structure in which a cylindrical body 2a extending in the left-right direction and a frame body 2b having an L-shape in side view are integrated. The L-shaped frame 2b receives the bottom surface and the opposing surface of the lower end of the seedling platform 1, and the receiver is designed to stop the pot-shaped part A placed on the seedling platform 1 from falling. A seedling receiving frame 2 is attached to the body side of the rice transplanter. The seedling platform 1 is configured to move back and forth laterally in conjunction with a left and right reciprocating device on the machine body side. In addition, the seedling receiving frame 2
A seedling dividing opening 3 is formed in the L-shaped frame 2b, and the pot-shaped part A that is fed out through the opening 3 is separated by a seedling dividing and transplanting claw described later.

Reference numeral 4 denotes rubber guides, which are made to hang downward from both left and right sides of the seedling dividing opening 3.

Reference numeral 5 denotes a seedling transplanter, which is attached to a lifting mechanism such as a double crank mechanism or a rotary arm, and has a vertical case whose tip side faces in the vertical direction, and is provided with a lifting rod 6 that projects outwardly and downwardly from the lower end side. A seedling engaging pusher 7 is attached to the lower end of this lifting rod.

8 is a seedling division transplantation claw, which is formed by bending a hard iron plate for cutlery as shown below. That is, the left and right side plate portions 8a, 8
a and the front plate part 8b are U-shaped in plan view, the left and right width of the lower side becomes narrower in front view, and the lower end is V-shaped, and in side view, the lower part widens toward the end, and the lower end extends from the front side to the rear. Formed in an inclined inclined surface 8C and a mountain-shaped portion 8d following the inclined surface 8C,
A notch groove 9 is formed in the front side plate portion upward from the apex of the lower end of the V-shaped portion, through which the leaf portion of the seedling can pass when dividing the seedling, and the left and right width of the upper portion of this notch groove is formed to be wide. .

The seedling dividing and transplanting claw 8 is fixedly fixed to the front end surface of the seedling transplanting tool 5 in a downward direction.

To explain the operation of this embodiment, a pot-shaped part in which seedlings are raised is made by turning a seedling container upside down, in which a large number of paper seedling growing pots 10 with germination holes formed in the bottom are connected on the left and right, front and back. A is placed and accommodated on the seedling mounting stand 1. Then, the front row of seedlings A is stopped by the seedling receiving frame 2 at its bottom side and lower end surface. In this state, when the seedling platform 1 is moved back and forth from side to side, the potted seedlings A are fed out one by one into the seedling dividing opening 3. At this time, the seedling dividing and transplanting claw 8 fixed to the front end side of the seedling transplanting tool 5 intervenes in the seedling dividing opening 3 from above.

Then, the seedling A is attached to the left and right side plate parts 8a, 8a and the front plate part 8.
A pot 10 of a pot seedling A is confined inside the lower end side of the pot 10, and a seedling engaging pusher 7 locks the upper surface of the pot 10 to push down the seedling A below a dividing opening 3 and split the seedling.

At this time, the bases of the leaves and stems of the seedlings A, which have grown several from the germination hole (A) of the pot 10, have not expanded due to the hole (A), so they are inside the narrow groove 9 on the lower side of the seedling transplant splitting claw 8. It is possible to extract the seedlings from the front side, and the upper part of the leaf and stem part expands as the leaves open, but since the groove 9 widens from side to side, the seedling can be transplanted without damaging the leaf and stem part. The extractor can be pulled out from the front side of the dividing claw 8, and the pot-shaped part A is surely divided and held by the dividing claw 8 and taken out downward, thrusting into the lower soil surface, and the seedling-engaging pusher 7 is rapidly moved. The seedling A is lowered, separated and released from the seedling transplanting dividing claw 8, and transplanted securely in a predetermined posture.

In addition, a guide member 11 such as a rod or plate that slides and guides the front lower end of the pot 10 made of spring material is provided at the lower front of the left and right intermediate portions of the seedling dividing opening 3, and a guide member 11 such as a rod or plate is provided at the rear lower end of the lifting rod 6. If a pot holder 12 made of a rod or plate for digging a hole is fixed to the back of the pot 10, it will be even better.
The layered seedling A can be divided with accurate dividing and holding posture, and can be reliably transplanted even in hard fields such as sandy soil.
