Description

[Detailed Description of the Invention] The present invention relates to a seedling stand for a seedling transplanter, and aims to provide a seedling stand that prevents seedlings from floating and improves operability.

In order to achieve the above-mentioned purpose, the present invention has been developed to provide a seedling platform 3 that is supported by the body 1 of a seedling transplanter and supplies seedlings to the seedling planting device 2. At least two seedling feeding devices 5, 5 having an interval 4 are provided, and a seedling detecting device 6 is provided in the spacing section 4 of the seedling holding devices 5, 5, and a seedling detecting device 6 is provided above the seedling mounting surface 3a of the seedling mounting table 3. A seedling holding device 7 is provided to prevent placed seedlings from floating up from the placement surface 3a, and the seedling holding device 7 is connected to a plurality of seedling holding bodies 7a, 7b, 7.
The length L of the seedling presser 7a provided above the seedling detecting device 6 is the same as the length L of the seedling presser 7b and 7c provided on the left and right sides of the seedling presser 7a.
A seedling stand for a seedling planting machine that is shorter than the previous model. ”, and this configuration provides the following effects.

That is, the seedling holding member 7a, which is relatively shorter than the other seedling holding members 7b and 7c, is placed above the seedling detection device 6 provided at the left and right intermediate portions of the seedling placement surface 3a to prevent the seedlings from floating up. Therefore, when the operator manually takes out the seedlings from the seedling placement surface 3a, the short seedling presser bodies 7a at the left and right intermediate portions of the seedling placement surface 3a do not obstruct the removal of the seedlings, improving work efficiency. The seedling pressers 7b and 7c on the left and right sides of the seedling placement surface 3a are in good condition.
Since it has a long structure, it is possible to reliably prevent the placed seedlings from floating up. Furthermore, since the seedling presser 7a prevents the seedlings from floating above the seedling detection device 6, it also has the effect of preventing erroneous sensing by the seedling detection device 6.

Hereinafter, embodiments of the present invention will be described based on the drawings.

A seedling feeding device 5 has a belt 24 with a locking protrusion for feeding the placed seedlings toward the seedling receiving plate 19 on its lower end side (the side of the seedling receiving plate 19). . is provided. Reference numeral 7 denotes a seedling holding device, the base of which is fixed to a shaft 7f supported by support stays 25, 25 provided on both left and right sides of the lower end of the seedling table 3, and which holds the seedlings along the seedling table surface 3a. Seedling holding bodies 7a, 7b, 7c, 7 extended toward the upper end of the mounting table 3
d and 7e, and the length l of the seedling presser body 7a, which is provided to be located directly above the seedling detection device 6 provided at the left and right center portions of the seedling placement surface 3a.
are seedling pressers 7b, 7 provided on both the left and right sides.
It is formed shorter than the length L of c. The seedling pressers 7d and 7e are provided on both left and right sides of the lower end of the seedling placement surface 3a, and the lower end of the seedlings received by the seedling receiving plate 19 floats due to the sliding resistance. This is provided to prevent the phenomenon of rising or rolling up.

Numeral 26 is a seedling stopper, which receives the front end of the seedling placed on the seedling placement surface 3a in its operating state (the state indicated by the two-dot chain line in FIG. 2), and stops the seedling to the appropriate seedling planting device 2. supply will be suspended.

The seedling detection device 6 is provided between the seedling feeding devices 5 and 5, and includes a sensing piece 6a that projects above the seedling placement surface 3a and a switch section 6b that is activated by the vertical movement of the sensing piece 6a. It is structured accordingly.
When there are no more seedlings on the sensing piece 6a of the seedling detection device 6, the sensing piece 6a moves upward, the switch part 6b is activated, and the warning light 27 provided at the front of the riding vehicle body 8 blinks. However, it is configured to notify the operator that the number of seedlings placed on the seedling placement surface 3a is running low.

When planting seedlings with the riding-type 5-row seedling transplanter configured as described above, the seedling mounting surface 3a of the seedling mounting table 3...
The seedlings placed on the seedlings are reciprocated from side to side with the seedling platform 3 by the seedling holding device 7 without causing any floating phenomenon, and the seedlings are divided into individual plants by the seedling planting device 2 and planted in the field. The feeding device 5 reliably sends out the seedlings toward the seedling receiving plate 19, and since the seedling holding body 7a of the seedling holding device 7 is provided above the seedling detection device 6, there is no possibility of damage caused by lifting of the seedlings. Malfunction of the seedling detection device 6 is less likely to occur.

On the other hand, when an operator manually takes out the seedlings on the seedling placement surface 3a, or when the seedlings are pulled out above the seedling placement surface 3a in order to perform fractional row planting for ridge treatment, the seedling stopper 26 is activated. Since the seedling holding bodies 7a at the left and right center portions of the seedling placement surface 3a are formed to be relatively short, the operator can easily grasp the placed seedlings with his/her hands, making the work easier and easier. Can be done quickly.

In the above embodiment, the seedling pressers 7d and 7e that prevent the seedlings from floating up at the lower end of the seedling placement surface 3a are provided on both left and right sides of the seedling placement surface 3a. It may be provided between the presser bodies 7a and 7c and between 7a and 7b.
