Abstract

PURPOSE:To provide the title feeder so designed that a preliminary seedling- loading device is supported through hooking in a detachable manner to the support, thereby ensuring preliminary seedlings to be readily replenished to the title feeder even in case some seedlings are left on said device. CONSTITUTION:Even in case preliminary seedlings W1 are left on the upper tier of a preliminary seedling-loading device 4, this device 4 in a titled attitude is detached from a support shaft 3 to pull out upward with tilt; thus the residual preliminary seedlings W1 is left to be loaded on a seedling-loading table 1 and the detached device 4 is newly loaded with preliminary seedlings, the resultant device 4 being then hooked and supported on a support shaft 3, thereby enabling the early replenishment of preliminary seedlings.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a preliminary seedling feeding device for a seedling planting device that enables continuous planting work in a wide field. A spare seedling placement device is installed above the inclined seedling placement table of the attachment device, and this preliminary seedling placement device is used to store spare seedlings! The present invention relates to a spare seedling supply device for a seedling planting device that is configured to be able to switch between a mounting position where the seedlings are left alone and an inclined position where the placed spare seedlings are placed downward.

[Conventional technology]

As a preliminary seedling feeding device for this type of seedling planting device, as disclosed in Japanese Utility Model Publication No. 57-29541, etc.
When the number of seedlings on the seedling holder is consumed and decreases, the lower tier of the spare seedling holder is sequentially switched to the inclined position, and the spare seedlings placed on the auxiliary seedling holder are sent to the lower seedling holder. There are some configurations that allow you to do so.

[Problem to be solved by the invention]

However, the preliminary seedling supply device configured in this way,
New spare seedlings cannot be replenished and placed on the spare seedling holder until the spare seedlings placed on the topmost tier of the spare seedling holder have been completely transferred to the seedling holder. Therefore, when planting in a large field by placing spare seedlings in several places along the edge of the ridge, even if the aircraft approaches the point where the spare seedlings have been placed, as long as the spare seedlings remain in the topmost spare seedling holder. This was inconvenient because it was not possible to replenish backup seedlings, and the backup seedlings could only be resupplied once the aircraft had left the location. In addition, when the number of spare seedlings remaining in the topmost spare seedling holder is low, flip up the spare seedlings, return the spare seedling holder to the mounting position, and then place the flipped up spare seedlings on the seedling holder. There is also a method of placing the seedlings on the seedlings and replenishing them with new spare seedlings, but this method is particularly troublesome for multi-row seedling planting devices.

The present invention has focused on the above-mentioned circumstances, and has an object of making it possible to easily replenish the spare seedlings to the spare seedling supply device even when some spare seedlings remain in the spare seedling mounting device. There is.

[Means to solve the problem]

A characteristic feature of the present invention is that the preliminary seedling holder is removably engaged with and supported by its support, and its functions and effects are as follows.

[For production]

That is, to explain this using FIG. 1 and FIGS. 5 to 7 as an example, by engaging the preliminary seedling holder (4A), (4B) and their support part (3), the preliminary seedling holder (4) The preliminary seedling loading device (4) can be removed from the preliminary seedling supplying device (D) by supporting it on the preliminary seedling supplying device (D) or by releasing the engagement.

Therefore, as shown in FIG. 6, even if there are some spare seedlings (Wl) remaining in the preliminary seedling holder, the preliminary seedling holder (4) can be attached to the support part (3) as shown in FIG. By disengaging and removing the seedlings in an inclined position, the spare seedlings (l) can be placed on the seedling holder (1) without having to turn them over.Then, the removed spare seedling holder (4) Place a new spare seedling (Wl) on the holder and place the spare seedling mounting tool (4) on the spare seedling supply device (0)!!By engaging and supporting the setting posture, you can supply the spare seedling (Wl). It can be carried out.

〔Effect of the invention〕

According to the present invention, even if some spare seedlings remain in the spare seedling holder, there is no need to turn up the spare seedlings and switch the spare seedling holder to the mounting position. In addition, since it is possible to replenish the spare seedling placement tool that has been removed from the spare seedling supply device, the replenishment work can be carried out easily. In particular, if the preliminary seedling holder is made in the same shape as the seedling scooping board, it is even more convenient because the seedlings can be directly scooped out from the seedling growing box and supported as they are on the preliminary seedling feeding device.

〔Example〕

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

As shown in Fig. 9, a seedling planting device (C) for planting multiple rows is installed at the rear of a riding-type traveling body (A) via a parallel four-speed linkage mechanism (B) so as to be able to rise and fall freely. It is configured as a rice transplanter.

The seedling planting device (C) is equipped with a seedling pedestal (1) for feeding that slopes forward at the upper end, and a preliminary mat-shaped seedling is placed on the top of this seedling pedestal (1). A preliminary seedling trough device (D) is provided for supplying (-1) to the seedling stand (1).

As shown in FIG. 1, the preliminary seedling gutter device (D) has a support shaft (3) horizontally fixed to the device frame (2) in two upper and lower stages,
Spare seedling placement tools (4) for placing preliminary seedlings (Ai) on each of these spindles (3) are rotatable via engaging portions (4a) integrally formed on the lower surface of the rear end side. , and are detachably engaged and supported, and a preliminary seedling mounting tool (4) and a mat-shaped preliminary seedling (Wl) are placed thereon while being engaged and supported by these support shafts (3). It is configured to be swingable and switchable between a placing position where the seedlings are placed on the table and an inclined position where the placed preliminary seedlings (Wl) are sent downward. In other words, a switching mechanism (5) using a solenoid is provided on the rear stay (6) corresponding to each spare seedling mounting tool (4), and a plunger (7) protruding forward from each switching mechanism (5) is provided. ) on the tip of each spare seedling (
By engaging and placing the tip of each switching mechanism (5), the horizontal placement posture is maintained.
When the solenoid (8) is energized and the plunger (7) retreats against the protruding biasing spring (9), the preliminary seedling loading tool (4), which is released from the engagement support at the tip, swings by its own weight. It is designed so that the rear part is tilted. The plunger (
7) is formed with a flat receiving surface (7a) for receiving the preliminary seedling holder (4) as shown in Fig. 4, and this receiving surface (7a) It also serves to prevent the plunger (7) from rotating by engaging with the protruding hole (6a) of the stay (6).

As shown in Figure 8, the spare seedling rack (4) is equipped with a handle (4b) at the rear end, just like a normal seedling board, so that it can be used to scoop mat-shaped seedlings directly from the seedling box. It is possible to take.

A contact-type first switch (SL) is provided on the cylinder pedestal (1) to detect when the seedlings (6) on the seedling pedestal (1) have been consumed and have become below a certain amount. There is.

When this first switch (SW + ) is turned on for the first time, the switching mechanism (5) in the lower stage is activated, and the preliminary seedling holder (4) in the lower stage is switched to the inclined position as shown in Fig. 5. At the same time, the seedling feed bell I-(10) installed on the seedling stand (1) is activated and the spare seedlings (-1) placed on the lower tier are activated.

Incidentally, the seedlings on the seedling stand (1) may be momentarily lifted due to the vibrations generated during running, and the first switch (SW, ) may be temporarily turned on. For this purpose, the first switch (S
Connect a delay timer to the first switch (SW
+) is configured to issue a detection signal only when it remains on for a certain period of time, to prevent malfunctions when the aircraft vibrates violently.

In this riding type rice transplanter, after completely feeding the spare seedlings (匈) from the spare seedling supply device (D), new spare seedlings (-1) are added.
The basic idea is to replenish. However, depending on the circumstances, even if there are some spare seedlings left in the upper reserve seedling holder (4), as shown in Figure 7, the slanted spare seedling holder (4) can be moved to 3) and pull it diagonally upward to place the remaining spare seedlings (Wl) on the seedling holder (1), and place the new spare seedlings on the removed spare seedling holder (4). If you place the seedlings and engage and support them on the support shaft (3),
Early replenishment is possible.

Example c] To carry out the present invention, as shown in Fig. 1O and Fig. 11, a pedestal (11
) may be swingably attached, and the preliminary seedling mounting tool (4) may be removably engaged and supported on this pedestal (11) via the protrusion (12) and the engagement hole (13).
