Abstract

PURPOSE:To prevent auxiliary seedling carrier units from disturbing when out of use by providing the auxiliary seedling carrier units at one end of the seedling carrier so as to enable regulation of movement from a position where the seedling carrier units are housed on the seedling carrying surfaces of the seedling carrier and a position projecting from the one end of the seedling carrier. CONSTITUTION:A seedling carrier 1 is constructed from seedling carrying surfaces (1a) and (1a), sidewall parts (1b)..., upper wall (1c) and a seedling feed belt and auxiliary seedling carrier units 2 and 2 are provided so as to enable passing through the upper wall (1c). Stoppers (2a)... for undetaching are secured to the tip parts of the auxiliary seedling carrier units 2 and 2 inserted and passed through the sidewall parts (1b)....

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a seedling planting machine equipped with a seedling mounting stand.

[Prior art and its problems]

Conventionally, there has been a seedling planting machine in which an auxiliary seedling holder made of a rod is fixed to the upper end of a seedling holder. However, the fixed auxiliary seedling carrier has a drawback that the temperature reaches 5 degrees when not in use, reducing the efficiency of seedling planting work.

[Means to solve the problem]

The present invention takes the following technical measures to solve the drawbacks of the prior art described above.

That is, in this invention, the auxiliary seedling holder 2 is placed at one end of the seedling holder 1 supported by the machine body, and the seedlings 1 of the seedling holder 1 are located at the storage position stored on the celebratory position 1a and at one end of the seedling holder 1. This seedling planting machine is characterized in that it is provided in an extended position protruding from the part and can be moved and adjusted freely.

〔Effect of the invention〕

With the above-mentioned configuration, when planting seedlings in a large field, this invention allows the auxiliary seedling mounting body 2 to be pulled out and used as an extended position to place more seedlings. On the other hand, in a narrow field, the auxiliary m attack body 2 is stored on the seedling loading surface 1a of the direct loading table 1, which improves work efficiency such as replenishing seedlings. Moreover, since the auxiliary seedling mounting body 2 is located on the seedling mounting surface 1a of the seedling mounting table 1, the movement resistance of the mounted seedlings is reduced, and the mounted seedlings can be moved satisfactorily.

The seedlings are planted at an appropriate planting depth using the seedling planting tool 5.

Especially when planting seedlings in a large field,
The auxiliary seedling loading body 2 can be pulled out and used as an extended position to load more seedlings, making it possible to avoid stopping the machine and going to the ridge to replenish seedlings as much as possible, making it more efficient. The mounting body 2 is stored on the seedling mounting surface 1a of the seedling mounting base 1 in a storage position, which reduces the amount of seedlings to be placed on the rear of the machine body and improves the front-to-back balance of the machine. Since the seedlings are placed on the seedling mounting surface 1a of the table 1, the movement resistance of the placed seedlings is reduced and the placed seedlings can be moved easily, and the occurrence of missing plants is prevented and the seedling planting operation can be carried out in a good manner.
