[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling stand for a rice transplanter.

[0002]

2. Description of the Related Art Conventionally, in a seedling mounting table of a multi-row planting type rice transplanter, only a set seedling of a specific row is taken out from a plurality of placed seedlings corresponding to each planting row at a ridge. There is a seedling stopper that prevents the transfer of the seedlings to the side, and has a function of switching between a state of blocking the transfer of the placed seedlings to the seedling take-out side and a state of canceling the blocked state.

[0003]

However, in the conventional example described above, since the seedling stopper for stopping the supply of the placed seedlings is simply provided on the seedling placing table, the seedling take-out side of the placed seedlings is provided. It was not possible to prevent the bed soil of the placed seedlings from rising in the state where the transition to the seedling was prevented, and it was not possible to reliably hold the placed seedlings on the seedling placing table.

[0004]

[Means for Solving the Problems] The present invention pivotally attaches a base end of a seedling stopper to a seedling placing table provided in an inclined posture such that the seedling take-out port is located at a lower position, near the seedling take-out port. By swinging the seedling stopper, it is possible to switch between a state in which the transfer of placed seedlings to the seedling take-out side is blocked and a state in which the blocking is released, while the seedling retainer is placed horizontally between the left and right side parts of the seedling stand. It is mounted on the seedling retainer with a retainer rod that acts directly on the bed soil of the placed seedlings to prevent it from rising, and a retainer rod that prevents the soil from rising and prevents the placed seedlings from moving. A certain seedling stopper relates to a seedling stand in a rice transplanter, which is arranged so as not to interfere with each other.

The support frame composed of the vertical rods 15 and 15 and the horizontal rods 16 and 17 is supported by the frame of the rice transplanter A through the above.

Reference numeral 19 is a seedling stopper provided on the lower front portion of the seedling placing table 3, and the number of seedling stoppers 3 is equal to the number of the seedling placing table 3, and a partition plate 3a for partitioning the number of the seedling placing table 3 is provided. To bracket
20 is attached, and the base end of the seedling stopper 19 is pivotally attached via a shaft erected on the upper end of the bracket 20.

The seedling stopper 19 is made of a flat plate having a width substantially the same as the seedling mounting width, and a slightly curved functional surface 19a is formed at the tip of the seedling mat to support the bottom surface of the seedling mat at a right angle. .

Further, the bracket 20 which is the base end pivot portion of the seedling stopper 19 is provided with a rotation stopper 21 for holding the seedling stopper 19 while locking the seedling stopper 19, and the seedling stopper 19 has a flat plate surface. A large number of vertical slit holes 22 are formed.

When there is a row which does not require planting of seedlings, the seedling stopper 19 is rotated to the position indicated by the phantom line in FIG. Can support and suspend planting. When the seedling stopper 19 is not used, the seedling stopper 19 can be rotated to the position indicated by the solid line in FIG. 2 and the position can be held by the rotation stopper 21 to prevent the spattering of muddy water when planting the seedlings. it can.

Reference numeral 23 denotes a seedling take-out opening provided at the lower end of the seedling placing table 3, and a bracket 20 for pivotally mounting the seedling stopper 19 is located near the seedling take-out opening 23. Numeral 24 is a seedling retainer fixed to both sides of the seedling placing table 3 through mounting gold 24a. The seedling retainer 24 is positioned higher than the attachment position of the seedling stopper 19 and is as follows. Is configured.

That is, as shown in FIG.
A support rod 24b is installed on the upper end of a, and a substantially L-shaped presser rod 24-1 is provided on the support rod 24b to prevent the seedling M from floating.
Is installed.

Further, the seedling retainer 24 is a retainer rod 24-1.
Are provided along the sliding and falling direction of the seedling placing table 3 and at a constant interval, and the bed soil of the placing seedling M is positioned between the pressing rod 24-1 and the placing seedling M is secured. It is held on the seedling mounting table 3.

In this embodiment, two pressing rods 24-1 are formed on the seedling pressing body 24, and the lower end of each pressing rod 24-1 is extended to the bracket 20 position. The presser bar 24-1 prevents the placed seedling M from rising.

Further, the seedling stopper 19 is constructed such that the functional surface 19a at the tip thereof is located within the working range formed in the front-back direction of the seedling retainer 24.

Further, as shown in FIGS. 3 and 4, a notch m is formed at the intersection of the tip of the seedling stopper 19 with the pressing rod 24-1 to prevent the seedling stopper 19 from being transferred to the placed seedling. At this time, the presser bar 24-1 is fitted in the notch m so that the seedling presser body 24 and the seedling stopper 19 do not interfere with each other.

The embodiment of the present invention is configured as described above, and the pressing rod 24-1 of the seedling pressing body 24 is extended to the bracket 20 position for pivotally mounting the seedling stopper 19. The presser bar 24-1 reliably prevents the placement seedling M on the seedling placement table 3 from rising. In addition, only a specific one of a plurality of placed seedlings corresponding to each planting line at the edge of the ridge is taken out from the seedling take-out port 23.
When planting in a blocked state without shifting to the side, the seedling stopper 19 is rotated forward around the proximal end pivotal portion, and only the desired seedling mat is formed on the functional surface 19a at its tip. It is for receiving and preventing sliding fall to the seedling take-out port 23, and when the seedling stopper 19 is rotated in this way to perform the blocking function, the pressing rod 24-1 of the seedling pressing body 24 is the seedling stopper.
Seedling stopper 19 that fits into notch m of 19 and does not interfere with each other
Thus, the function of locking the placed seedling can be fully achieved.

The seedling stopper 19 receives the front end face of the placed seedling M by the seedling stopper 19 because the functional surface 19a at the tip of the seedling stopper 19 is located within the working range of the seedling retainer 24 in the front-back direction. In this state, the front portion of the placed seedling M is prevented from floating in a curved shape due to the weight of the entire seedling, and the placed seedling M is prevented from having a curved habit.

The seedling stopper 19 is appropriately held by a rotation stopper 21 provided on the bracket 20.

Further, the rotary stopper 21 may be any one as long as it holds the seedling stopper 19, and the shape and mounting position are not limited to those in the above embodiment. Moreover, the rotation stopper 21 can change its mounting position depending on the situation of the placed seedling M.

[0022]

According to the present invention, by swinging the seedling stopper, a state of preventing the transfer of the placed seedlings to the seedling take-out port side,
While it can be switched to the blocking release state, a seedling retainer is laid horizontally between the left and right sides of the seedling placing table, and the retainer that prevents the floating by directly acting on the bed soil of the placed seedling on the seedling retainer. Since the rods are attached and the holding rods that prevent floor soil from floating and the seedling stoppers that are in the transfer prevention state of the placed seedlings are arranged so as not to interfere with each other, the following effects are achieved.

Since it is possible to prevent the bed soil of the placed seedlings from rising in the state where the transfer of the placed seedlings to the seedling take-out port side is prevented,
The placed seedlings can be reliably held on the seedling placing table, and the seedling pressing body does not interfere with the seedling stopper, so that the seedling stopper can sufficiently perform the placed seedling locking function.
