Description

[Detailed description of the invention] [Industrial application field] The present invention is such that the seedling stand is formed using a bottom plate on which planted seedlings are placed and a side wall on the side of the bottom plate. This relates to the structure of a seedling stand in a rice transplanter.

[Problems to be solved by the prior art and the invention] Today, in the seedling stand of this seed rice transplanter, the bottom plate on which the planted seedlings are placed and the side walls on the sides of the bottom plate are made separately. There is a device in which these are integrally assembled and fixed using fixing means such as rivets. However, in this case, the side wall body and the bottom plate were conventionally simply fixed together, so the strength of the side wall body was weak, and as a result, the outer width of the side wall body tended to increase. ,
When this happens, the effective seedling placement width becomes narrow on the bottom plate side, and the planted seedlings become pinched between the left and right side walls, making it difficult to carry out vertical feeding smoothly, so this is not desirable. isn't it.
Therefore, in order to avoid this, the side wall body must be made strong using additional reinforcing means, which poses a problem.

[Means for solving the problem] The present invention was created in view of the above-mentioned circumstances with the aim of providing a seedling stand structure for a rice transplanter that can eliminate these drawbacks. In a rice transplanter in which a seedling mounting stand is formed using a bottom plate on which planted seedlings are placed and a side wall body on the side of the bottom plate, the bottom plate and the side wall body are used to hold the planted seedlings placed on the bottom plate. It is characterized in that the vertical feed mechanism for seedlings is integrally fixed with the support plate to which it is assembled.

According to the present invention, with this configuration, the side wall body can be reinforced by effectively using the support plate necessary for assembling the vertical feed mechanism, without using any special reinforcing means.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a planting section attached to a passenger-type traveling body (not shown);
These include a planting claw 2, a float 3, a seedling platform 4 with a high front and low rear shape, which will be described later, a planting section frame 5, and a vertical seedling feeding mechanism 6.
The construction of these members is the same as before.

The seedling mounting stand 4 is constructed using a bottom plate 7 on which planted seedlings are placed corresponding to each seedling mounting row, and side wall bodies 8 having a substantially hat-shaped cross section and located on both left and right sides of the bottom plate 7. However, these bottom plate 7 and side wall body 8 are arranged so that side 7a of the bottom plate and flange 8a of the side wall body are used as a vertical feeding mechanism for the planted seedlings placed on the bottom plate 7, as will be described later. It has a three-layer structure together with a support plate 9 necessary for assembly, and is assembled by integrally fixing it with fixing devices 10 such as rivets.

A bracket 13 is integrally fixed to the bottom surface of the support plate 9 by a bolt 12 that passes through the support plate 9 from below and is screwed into the top of the side wall 8. This bracket 13 has three supporting shafts 1.
4, 15, and 16 are pivotally supported, and the front side (inclination upper side) support shaft 14 is supported in the elongated hole 13a so as to be movable back and forth while being urged forward by the ammunition 17. A driven pulley 19, around which a vertical feed belt 18 is suspended, is rotatably supported on the support shaft 14. On the other hand, a drive pulley 20 is integrally supported on the rear support shaft 16 via a stop bolt 20a, and a ratchet gear 21 is integrally supported. This gear 21 has a claw body 21a.
are intermeshingly supported to form a one-way rotating clutch. Then, when the seedling mounting table 4 reaches the left and right moving ends in accordance with the seedling mounting operation, the operating lever 22 moves the driven lever 23, which is pivoted to the intermediate support shaft, upwardly as shown in FIG. The ratchet gear 21a rotates in conjunction with the pushing of the seedlings, which causes the drive pulley 20 to rotate to vertically feed the vertical feed belt 18 downward by one plant. A vertical feed mechanism is configured. In addition, 24
24 is a switching lever, and by operating the switching lever 24, the operation of the vertical feed mechanism can be freely regulated.

Further, the longitudinal belt 18 is integrally formed with a convex belt guide 18a on the inner circumferential surface of its side edge. are integrally extended.

In the embodiment of the present invention constructed as described above, the seedling stand 4 includes a bottom plate 7, a side wall body 8, and a support plate 9.
By fixing them together with rivets 10, they are assembled into a three-part structure, and the side wall body 8 assembled in this way is
It will be strongly reinforced by the support plate 9.
That is, a support plate 9 is interposed and fixed to the side wall body 8 so as to extend between the both flanges 8a. As a result, the side wall body 8 is firmly fixed, and it is possible to reliably prevent problems such as the side wall body 8 opening outwards as in the conventional case, and this makes it possible to effectively place seedlings on the bottom plate 7. The width can be maintained at a predetermined width corresponding to the horizontal width of the planted seedling. Therefore, the planted seedlings do not have the problem of being pinched by the side wall body 8, and reliable vertical feeding is achieved by the operation of the vertical feeding mechanism, allowing highly accurate seedling planting. become. The support plate 9 that reinforces this side wall body 8 is not a separate dedicated member, but is an attachment member for the bracket 13 necessary for attaching the vertical feeding mechanism to the seedling stand, so it can be used for multiple purposes. This greatly contributes to simplifying the structure and improving assembly workability.

In addition, in this case, the bottom plate 7 is extended to the inside of the vertical feeding belt 18 to form a support portion 7b to support the vertical feeding belt 18, so that the vertical feeding belt 18 can be bent. However, in this case, the support portion 7b has a thick wall. It is configured to support the belt guide 18a portion which has excellent strength. For this reason, the amount of deflection of the vertical feed belt 18 cannot be reduced compared to a belt that supports a thin portion, and the support portion 7b
However, it is convenient because it functions as a scraper for scraping off mud adhering to the belt guide 18a.

[Operations and Effects] In summary, since the present invention is constructed as described above, the side wall body and the bottom plate are fixed as a three-part structure together with the support plate necessary for attaching the vertical feed mechanism. Therefore, the side wall body is strongly reinforced by the support plate, and problems such as an increase in the outer width can be reliably avoided. For this reason, the effective seedling placement width of the bottom plate is narrowed and the planted seedlings are not pinched by the left and right side walls, and the planted seedlings are
Smooth vertical feeding allows for highly accurate planting work. Moreover, this side wall is reinforced by effectively utilizing the support plate required to install the vertical feed mechanism without using a separate dedicated reinforcing member, which allows parts to be used for multiple purposes, simplifying the structure. This will make a great contribution.
