いる。2. Description of the Related Art Conventionally, soiled seedlings received by a seedling feeding conveyor are sorted into good seedlings and bad seedlings by a seedling sorting conveyor, and only good seedlings are conveyed and supplied to a seedling planter for desired transplantation. There are various kinds of transplanting machines as described above, and in particular, as a seedling selecting / conveying apparatus including the seedling supplying conveyor and the seedling selecting conveyor, for example, one described in Japanese Patent Publication No. 3732 is known.

短一対の転送コンベア5,6を縦方向に張架している。As shown in FIG. 5, in this seedling selecting / conveying apparatus, the seedling supplying conveyor 1 and the seedling selecting conveyor 2 both convey the soil-laden seedlings P in the direction orthogonal to the traveling direction of the machine body. However, they are installed upside down at required intervals with their conveying directions reversed, and a conveying speed is set between the sending end 3 of the seedling supply conveyor 1 and the receiving end 4 of the seedling selection conveyor 2 thereof. A pair of long and short transfer conveyors 5 and 6 which are set faster than the supply conveyor 1 are vertically stretched.

け搬送するものである。In the long transfer conveyor 5 described above, the upper end portion 7 is opposed to the front side of the delivery end 3 of the seedling supply conveyor 1, and the delivery end 3 of the seedling supply conveyor 1 and the retaining ring 8 are provided. The soil-embedded seedlings P protruding from the space are brought into contact with the upper end portion 7 to be separated from the succeeding soil-embedded seedlings P and directed downward at a speed faster than that of the seedling feeding conveyor 1 in cooperation with the short transfer conveyor 6. It is to be transported.

もまた同じように高速でなければならない。In other words, the long transfer conveyor 5 is faster (actually 3 to 5 times faster) than the seedling feeding conveyor 1 in order to separate the soil-laden seedlings P continuously fed from the seedling feeding conveyor 1 from the succeeding ones. The transfer conveyor 6 is short in order to cooperatively convey the separated soil-bearing seedlings P.
Must also be similarly fast.

The front side is an inclined traveling section 30 that travels obliquely downward and outward. Outside the inclined traveling section 30, an inclined conveyor 33 having the same conveyance speed as the seedling feeding conveyor 19 and the inclined traveling section 30 positions its upper end portion 34 in front of the delivery end portion 29 of the seedling feeding conveyor 19. Lower end 35
Is placed above the receiving end side of the seedling selection conveyor 20 and stretched. A seedling separating wheel 39 having a peripheral speed higher than the conveying speeds of the seedling supply conveyor 19, the inclined traveling unit 30, and the inclined conveyor 33 is provided between the lower end portion 35 of the inclined conveyor 33 and the receiving end side of the seedling selection conveyor 20, and It is mounted at a position facing the lower end of the inclined traveling unit 30.

Separated into individual pieces by the seedling separation wheel above the receiving end side of the seedling selection conveyor and received by the seedling selection conveyor,
Therefore, a selection is made between good products and defective products.

とか姿勢を乱すとかいうことがない。Since the seedling supply conveyor has an inclined traveling portion ahead of its delivery end portion, and therefore the delivery end portion and the inclined traveling portion are continuous with each other, the transfer of the soil-bearing seedling from the delivery end portion to the inclined traveling portion is performed. Is performed smoothly without rocking, and moreover, since the delivery end portion and the inclined traveling portion and the inclined conveyor have the same conveying speed, the rotating force is not applied to the soil-grown seedlings being sandwiched and conveyed, There is no need to let the soil-attached seedlings pass through or disturb the posture.

すおそれがない。[0015] Since the close row soil seedlings are separated into individual pieces by a separating wheel at a position close to the receiving end side of the seedling selection conveyor, each soil seedling is immediately received by the receiving end at a short distance. It will not collapse or drop when it is received. In addition, unlike the case where the soil-seedlings after separation are further conveyed by sandwiching the required distance with a belt at a relatively high speed and then received by a seedling selection conveyor, there is no risk of causing trouble during the conveyance.

It is dropped from the mouth 28 and discharged to the outside of the system. That is, the seedling selection conveyor 20 temporarily receives all the soil-embedded seedlings P on the receiving end side, but eventually selects only the soil-embedded seedlings P that are good seedlings and conveys them to the next-stage parallel conveyance conveyor 49. It is a thing.

奏する。[Effect of the Invention] As is clear from the above description,
According to the seedling selecting / transporting device of the transplanter of the present invention, the following effects can be obtained.

れる。The soil-added seedlings supplied in a close row by the seedling supply conveyor are conveyed while being held in a close row between the sending end portion of the seedling supply conveyor, the inclined traveling section and the inclined conveyor, and the seedling selection conveyor conveys the seedlings. Above the receiving end side, the seedlings are separated into individual pieces by a seedling separating wheel and are received by the seedling sorting conveyor, where the sorting of good products and defective products is performed accurately and smoothly.

を作用させることがないから、該土付苗に土抜けさせる
とか姿勢を乱すとかいうことがない。Since the seedling supply conveyor has an inclined traveling portion ahead of its delivery end portion, and therefore the delivery end portion and the inclined traveling portion are continuous with each other, the soil seedlings are transferred from the delivery end portion to the inclined traveling portion. Is performed smoothly without rocking, and moreover, since the delivery end portion and the inclined traveling portion and the inclined conveyor have the same conveying speed, the rotating force is not applied to the soil-grown seedlings being sandwiched and conveyed, There is no need to let the soil-attached seedlings pass through or disturb the posture.

すおそれがない。The close row of soil-grown seedlings are separated into individual pieces by a separating wheel at a position close to the receiving end side of the seedling selection conveyor, and each soil-grown seedling is immediately received by the receiving end at a short distance. It will not collapse or drop when it is received. In addition, unlike the case where the soil-seedlings after separation are further conveyed by sandwiching the required distance with a belt at a relatively high speed and then received by a seedling selection conveyor, there is no risk of causing trouble during the conveyance.

ていることを特徴とする移植機の苗選別搬送装置。1. A seedling feeding conveyer for conveying soil-grown seedlings in a direction orthogonal to the traveling direction of the machine body, and a soiled seedling in a direction also orthogonal to the traveling direction of the machine body and opposite to the seedling feeding conveyor. In a seedling sorting and conveying device of a transplanter, which is constructed by vertically stacking a seedling sorting conveyor for transporting the seedling sorting conveyor at a predetermined interval, the seedling feeding conveyor travels diagonally downward and outward from the delivery end. Being an inclined traveling part, an inclined conveyor having the same conveying speed as that of the seedling feeding conveyor and the inclined traveling portion is provided outside the inclined traveling portion, and its upper end is opposed to the front of the delivery end of the seedling feeding conveyor. It is positioned and the lower end is located above the receiving end side of the seedling selection conveyor and stretched, and the seedlings having a peripheral speed higher than the conveying speed of the seedling supply conveyor, the inclined traveling section and the inclined conveyor. The wheel is between the lower end of the inclined conveyor and the receiving end side of the seedling selection conveyor, and is aerial at a position facing the lower end of the inclined traveling portion, the transplanter characterized by Seedling sorting and conveying device.
