Abstract

PURPOSE:To prevent growth inhibition and irregularity caused by excess fertilization by simultaneously stopping fertilization to a row and line for planting seedlings where planting operation is stopped in case of stopping a proper number of operations for planting seedlings by a rice transplanter for multi-row planting. CONSTITUTION:A shutter of a delivery device of a left fertilizer distributor is operated by a wire 43a so as to cover the upper surface of a rotating roll and fertilization to the two left interrow spaces is stopped when a clutch 19 of a left seedling-planting unit is disengaged through a wire 41a by a clutch lever 40a.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice transplanter equipped with a fertilization device, which is conventionally configured to apply fertilizer in accordance with each seedling pricing position of each seedling planting device of a multi-row rice transplanter. Rice transplanters with fertilization devices were known, but multi-row rice transplanters
During seedling pricing work, when the end of planting in the field approaches, seedling planting by some of the seedling planting devices out of all the seedling planting devices is stopped and a small number of rows of seedlings are planted to avoid leaving any unplanted seedlings. This is performed before the final seedling pricing process, and in the final seedling pricing process, an operation is adopted in which seedlings are planted using a full seedling planting device so that no seedlings are left unplanted up to the edge of the ridge.

In this case, with conventional multi-row rice transplanters, fertilization is applied to the rows of missing plants where seedling planting has been stopped, and fertilizer is applied again when seedlings are to be planted in the rows of missing plants in Kameko in the next process. As a result, excessive fertilization was applied, and when planted, there were disadvantages such as the growth of seedlings being inhibited, and medium growth spots occurring.

Therefore, the present invention has taken the following technical measures for the purpose of eliminating the drawbacks of the conventional device described above.

That is, the present invention provides a single or (33) multi-row rice transplanter.

It is configured so that it can be turned off.

(43 &), (48b) are the respective fertilizer application devices (33), (
When the left clutch (19) is disengaged, fertilization on the left side is stopped and the central clutch ( 19) are interlocked and connected so that when the corresponding center fertilization is stopped.

In the figure, (45) is a preliminary seedling mounting stand, and the towing vehicle body (1)
A rotating link (46) on the side and a rotating telescopic link (47) that is rotatable and extendable are provided behind the pilot seat (5). And this spare seedling mounting stand (45)
In the lower space of the fertilizer application device (38), the hole/rear (34) part of the fertilizer application device (8s) is arranged.

In the upper configuration, after placing the seedlings in the seedling tank (9) and filling each hopper (34), (34) of the fertilizer application device with fertilizer, the rice transplanting device (7) is lowered and the land preparation flow is adjusted.
) (11) is grounded on the soil surface, the rice transplanting device (7) is towed by the towing vehicle body (1), and the rotating parts are rotated by transmission.

Then, the seedling planting devices (lO), (10)... move back and forth from the seedling tanks (9), (9)... to the left and right, dividing the seedlings into individual plants (land preparation flow) (IIL ( 11)・
・Plant the seedlings on the soil leveled by the lateral protrusions. In addition, at the same time as the seedling pricing operation, the fertilizers (3(), (8)
The feeding device (35) of 3) is activated, and the rotation low/L/(

) is released into the groove between (11) and (11) and fertilized.

In this way, fertilization work is carried out at the same time as the seedling pricing work, but when the seedling pricing work is nearing the end in the - field, due to the multi-row rice transplanter, all the seedling plantings are done. Device(
10), (lO)... When the last round of seedling planting is carried out, a wide width of remaining seedlings may occur between the ridge and the final seedling pricing row.

In such a case, before the final seedling pricing process, the clutch (19) of the seedling planting device located on the rice storage area side of the rice transplanter, for example the left seedling planting device in Fig. 2, should be moved to the clutch lever. -(4
0Fs) through the wire (41a) to stop planting the two seedlings on the left side. At this time, the shutter (38) of the feeding device (35) of the left fertilizer application device (33)
) is operated by a wire (43a) so as to cover the upper surface of the rotating row/L' (45a), and at the same time, fertilization between the two seedling pricing rows on the left side is stopped.

Then, in the final seedling pricing step, the operation of the left seedling planting device is restarted and the seedling pricing work is carried out to avoid leaving any unplanted plants.

Since this invention has the above-mentioned configuration, during seedling pricing work,
For the purpose of reducing the width of residual piles at the edges of field ridges,
When stopping the process of pricing the appropriate number of seedlings on the multi-row rice transplanter,
The fertilizer application to the stopped seedling pricing rows can be stopped at the same time, and the fertilizer is applied even to the part where seedling planting has been stopped, and when seedlings are planted in this part again,
There is no inconvenience such as being fertilized, therefore,
It has the effect of preventing growth inhibition and growth spots caused by excessive fertilization.

In addition, on the implementation site side, a structure was adopted in which a fertilization device was installed for each two-row seedling pricing unit. It goes without saying that the attached clutch and the corresponding fertilizer application device may be configured in an interlocked manner.
