Description

[Detailed description of the invention] The present invention relates to an improvement of a transplanter equipped with a transplant tube that can be opened and closed so that it can be raised and lowered, and in particular, it includes a means for intermittently spraying a spray liquid such as water or a chemical solution onto the transplant tube. Regarding what is equipped.

A device is known in which seedlings are placed in a transplant tube that can be opened and closed, and the seedlings are raised and lowered to be transplanted at predetermined pitches. This device is particularly convenient for multi-cultivation, as it enables so-called drilling and transplanting at the same time.

However, since conventional transplanters of this type are not equipped with a liquid sprinkling means, there are some problems in terms of the ability of seedlings to take root.

Furthermore, when a dispersing means is attached, the communication pipe for dispersing liquid conduction becomes entangled with the lifting device and opening/closing device as the transplant tube moves up and down and opens and closes, and not only does good conduction occur, but also the communication pipe becomes impossible. In some cases, it may become damaged or damaged.

The present invention was devised in view of the above-mentioned circumstances, and its purpose is to ensure good rooting and growth of seedlings by providing a means for intermittently spraying a spray liquid into the transplant tube. To provide a transplant machine.

In this open position, in the embodiment, the electric pump 5 is activated, and the material to be sprayed passes through the connecting pipe 38 to the opening 36A of the spreading tool 36.
It is dispersed into the cylinder.

Therefore, during planting, the seedling A left in the hole C is sprayed with a spray material not only at the base of its root but also around it to improve the rooting ability of the seedling A.

In addition, since the transplanting tube 21 is sprayed when it is in an open position, the amount of spraying can be the minimum necessary, and the sprayed material is scattered inside the tube and flows smoothly down using the bottomed wall as a guide, thereby eliminating waste. Nor.

Further, since the communication pipe 38 forms a conductive portion using the rod 32A of the opening/closing device 32 or the rod 28A of the lifting device 28 as a pipe structure, the portion that may become entangled with the movable member can be minimized.

In addition, since the first and second tubes 38A and 38B of the communication tube 38 are flexibly bent, they can conveniently follow the opening/closing operations and lifting/lowering operations of the transplant tube 21.

Of course, seedling A does not have to be a seedling with soil.

The present invention is as described above, and effectively achieves the intended purpose by providing excellent rooting and growth of seedlings, less entanglement of liquid pipes, smooth operation, and increased yield. It is very profitable.
