Description

[Detailed description of the invention] The present invention provides a sliding plate for receiving and supporting the seedling take-out opening of a seedling stand that can be moved laterally in a reciprocating manner, and for guiding the lateral movement of the seedling stand. Seedlings in a rice transplanter in which the table is separated midway in the direction of movement and is divided into a fixed sliding plate and an extended sliding plate, and the extended sliding plate is detachably attached to the fixed sliding plate. This invention relates to an extension structure of a sliding plate of a platform.

In general, the sliding plate that slidably supports the seedling tray has a width in the left and right direction that is greater than the width of the seedling tray so that it can reliably support the seedling tray throughout its entire reciprocating movement stroke. The sliding plate is longer by the stroke, and this sliding plate protrudes greatly outward from the side of the aircraft, making it easily deformed and damaged by colliding with other objects when traveling on the road or when stored. Like the plate extension structure, it is divided into a fixed sliding plate and an extended sliding plate, and the extended sliding plate is detachably attached to the fixed sliding plate, and the extended sliding plate can be used when not working. Although it is made to be removable, conventionally, for example, as described in Japanese Utility Model Application Publication No. 53-33625,
If the seedling take-out ports formed on the sliding plate are divided into a fixed sliding plate and an extended sliding plate at a midway point between adjacent seedling take-out ports, seedlings will not be removed from the extended sliding plate either. If the relative position of the extended sliding plate with respect to the fixed sliding plate shifts due to the formation of the ejection port,
There is a problem that the seedlings cannot be removed smoothly.

Furthermore, since it is divided midway between the adjacent seedling take-out ports, the lower end of the seedling tray is always located at this dividing point, and the seedlings will fall from the seedling tray side to the sliding plate side. There is a strong possibility that muddy soil may remain without being scraped out, and the insertion connecting part that connects the fixed sliding plate and the extended sliding plate is a sliding guide plate that slides and guides the back side of the seedling stand. By being composed of an L-shaped insertion cylinder part and an L-shaped insertion connection protrusion that spans the front wall of the seedling holder and the front wall of the seedling receiver,
The mud that has accumulated at the intersection of the sliding guide plate and the front wall of the seedling holder enters the insertion tube, and this mud clogs the extension sliding plate against the fixed sliding plate. However, the problem is that the above-mentioned problem is more likely to occur.

In view of the above-mentioned circumstances, the present invention is designed to stably support the seedling stand without wobbling during planting work, while also making it possible to reliably take out the seedlings. The purpose of the present invention is to provide an extension structure for a sliding plate of a seedling stand that can be easily connected to the position of the slider.

The characteristic structure of this invention to achieve the above purpose is as follows:
In the extension structure of the sliding plate of the seedling loading table in the rice transplanter mentioned above, the sliding plate is separated at a midway point on the outside beyond the position of the seedling take-out port on the most lateral side, and the sliding plate is separated from the fixed sliding plate and extended sliding plate. The sliding guide plate section is divided into a plate, and the sliding guide plate section slides and guides the rear side of the seedling stand and the front wall section of the seedling receiver is located away from the intersection of the sliding guide plate section and the front wall section of the seedling receiver. A locking protrusion for connecting an insertion cylinder connected to one of the fixed sliding plate and an extended sliding plate is connected to the other at two places with the wall in the direction of lateral movement of the seedling stand. The present invention is characterized in that an insertion connecting portion is formed which can be inserted into the fixed sliding plate and the extended sliding plate in such a manner that the fixed sliding plate and the extended sliding plate can be connected by insertion and can be pulled out and separated.

That is, since the sliding plate is divided into a fixed sliding plate and an extended sliding plate in the middle of the outer part beyond the position of the seedling taking-out port on the most lateral side, the position of the seedling taking-out port can be changed. Seedlings can be taken out reliably without any misalignment, and the lateral side of the seedling stand can be positioned closer to the center of the machine than the dividing position of the sliding plate, allowing the muddy soil at the dividing position to be scraped out. Therefore, the extended sliding plate can be attached to and detached from the fixed sliding plate with little remaining.

In addition, there are two locations: the sliding guide plate part that slides and guides the back side of the seedling stand and the front wall part of the seedling receiver, which is located away from the intersection of the sliding guide plate part and the front wall part of the seedling receiver. In other words, avoid locations where mud tends to remain,
Since a plug-in connection part is formed, the extension sliding plate is fixed in a state where mud is difficult to get stuck in the plug-in tube part due to the fact that there is little mud remaining at the splitting position mentioned above. This has the effect of making it easier to connect to a predetermined position.

Further, as the two insertion cylinder parts for inserting and connecting the extension sliding plate, a reinforcing cylinder part integrally formed with the sliding guide plate part of the fixed sliding plate and the front wall part of the seedling receiver may be used. In this case, there is no need to separately provide a special insertion cylinder for inserting and connecting the extended sliding plate, and there is an advantage that the sliding plate structure can be simplified.

Furthermore, if the two insertion and connection locking protrusions of the extension sliding plate are configured to have different protrusion lengths, the longer locking protrusion with respect to the fixed sliding plate By simply aligning the locking projections, the shorter locking projections can be automatically aligned as the locking projections are inserted and moved, so the protruding lengths of both locking projections are made equal. Compared to the case
There is an advantage that the extension sliding plate can be easily inserted and connected.

Embodiments of the present invention will be described below based on the drawings.

Fig. 1 shows a rear-mounted riding rice transplanter, which is mounted at the rear of a traveling body 5 which is equipped with a pair of left and right wheels 3 and 4 on the lower side of an engine 1 and a transmission case 2 connected thereto. , a forward-leaning seedling platform 6 that can freely move back and forth with a constant stroke in left and right directions, a planting mechanism 7 that takes out seedlings in units of planting from this seedling platform 6 and sequentially plants them on the mud surface;
