Abstract

PURPOSE:To obtain a seedling transplanter enable of transplanting without mutual entanglement of seedling roots by providing an endless rotating belt for longitudinal sending having bosses sending crop seedlings laid on a seedling- loading stage to a seedlings-taking out port and protruding a finishing end side of the belt so as the rotation-operating face to be the same level as the seedling-loading face. CONSTITUTION:Many crop seedlings divided from mother strain of rush, etc., are laid on a seedling-loading stage in longitudinal rows and are taken out from a seedlings-taking out port, then transplanted. In said seedling transplanter, the seedling transplanter is connected to a traveling machine body in a vertically movable state by a link mechanism 1 and an endless rotating belt 14 for longitudinal sending having bosses sending crop seedlings laid on a seedling-loading stage 3 having an attitude inclined to rear side reciprocating to left and right in a constant stroke to a transplanting-transmission case 2 co-used as a frame to a seedling-taking out port 5 is provided, then at least a sending-finishing end side of the endless rotating belt 14 having bosses is protruded so as a center position of the rotation to be an approximately same level as the seedling-loading face 13a in the seedling-taking out port 5.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for planting crop seedlings, which have been divided from mother plants such as rushes, by placing them in vertical rows on a multi-sided platform and taking them out from the seedling outlet. More specifically, the present invention relates to a seedling transplanter equipped with an endless rotating belt with a protrusion for vertically feeding crop seedlings placed on a seedling tray toward a seedling take-out port.

[Conventional technology]

In the above-mentioned seedling transplanting machine, conventionally, the endless rotating band with projections is provided with its rotation surface at a low position approximately on the same level as the seedling placement surface at the seedling take-out port, and only the feeding projection is used for seedlings. It had a structure that protruded from the mounting surface.

[Problem to be solved by the invention]

However, in the above-mentioned conventional structure, the roots of the seedling rack device for crop seedlings are at the same level as the target seedlings and the subsequent seedlings when planting at the seedling take-out port, so when the seedling rack is moved horizontally, the seedlings are vertically moved. There was a drawback that the target seedlings and subsequent seedlings were tangled with each other during planting, and the separation was not sufficient, and during the planting operation, the roots became tangled with each other, making it impossible to plant smoothly.

The present invention aims to solve the above-mentioned problems.

[Means to solve the problem]

A characteristic configuration of the present invention is that in the seedling transplanting machine described at the beginning, at least the feed end side of the endless rotating belt with projections is
The center of rotation thereof is located at a point where it is protrudingly placed at approximately the same level as the seedling placement surface in the seedling take-out port.

[For production]

With Q, in which the end side of the endless rotation belt protrudes greatly, during vertical feed rotation, the target seedlings are dropped from the feeding surface of the endless rotation belt to the seedling placement surface at the seedling take-out port, and subsequent seedlings are It will be sent out in a state where it is reliably separated from the other parts.

Moreover, the terminal end of the endless rotation belt is at the center of rotation or at the seedling end.

Since it is approximately the same level as the drawing, the part facing the target seedling should be planted in an almost vertical position, and the planting should be done so that the roots of the engraved seedlings can spread upward in the feeding direction and crawl back. It can be prevented.

〔Effect of the invention〕

Therefore, according to the present invention, by simply changing the position of existing cuttings in a more rational manner than in the past, it is possible to reliably separate target seedlings from subsequent seedlings, and to ensure smooth operation of planting. This means that the number of seedlings planted can be equalized.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

Figure 1 shows a rice grass seedling transplanter. This seedling transplanter is
It is connected to the traveling body (not shown) via a link mechanism (1) so as to be able to rise and fall freely, and the planting transmission case (
2), the seedling tray (3) is tilted downward after reciprocating from side to side with a partial stroke, and a sliding rail (3) that supports the lower end of the seedling tray (3) so that it can slide freely. From the seedling take-out port (5) formed in 4), the planting claw (6) takes out the seedlings one by one and plants them.
), the seedling holder (7) is configured to forcibly feed the seedlings toward the seedlings. The seedling holder (7) has a pair of front and rear swing links (8a) on the upper side of the planting transmission case (2).
8b), and a pair of left and right holding claws (7b) attached to the front end of the support arm (7a) so as to be able to swing relative to the arm (7a). Insert the swing link (8a) on the front side into the planting claw (6).
The holding claw (7b) is moved into the seedling by swinging back and forth by the cam (10) and return spring (11) provided on the sliding drive shaft (9) of the driving support planting arm (6a). The cam is configured to be driven to move back and forth between the state and the rearwardly retired state, and also relatively swings the holding claw (7b) downward in accordance with the relative swing between the swing link (8a) and the support arm (7a). It is equipped with a mechanism (12).

The seedling stand (3) supports a large number of strawberry seedlings divided from the mother plant in an upright position, and at the end of the horizontal movement stroke, the seedlings are placed on a part of the planting claw (6) side. The seedlings are sent out toward the take-out port (5) by an endless rotation band (14) with a protrusion provided in a state that projects above the seedling placement surface (13a) at the take-out port (5).

Moreover, the seedling placement surface (13) on the upper side of the endless rotating belt (14)
b) is configured to be located above the endless rotating belt (14), and as shown in Fig. 2, the seedling storage device for supplying new seedlings (
15) on the seedling stand (3), and when pulling out the seedling scooping plate (16) upward for supporting the seedlings, remove the seedling scooping plate (16).
16) so that the extraction operation is not obstructed by the protrusion (14a) of the endless rotation band (14).

Then, the terminal end side of the endless rotating belt (14) is widened so that the center position of the sliding pulley (17) is located at approximately the same level as the seedling placement surface (13a) at the seedling take-out port (5). It is placed prominently.

In this way, in vertically feeding planting, target seedlings are sent into the seedling take-out port (5) with a large drop, so separation from subsequent seedlings is reliably performed.
With the lateral movement of step 3), it is received by the lower edge of the endless rotating band (14), and it is possible to prevent it from returning due to upward widening.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
