Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a fertilizer application machine having a fertilizer application section and a ground operation section such as a sowing section or a transplantation section, for example, a fertilizer application and seeding machine. The present invention relates to a storage device of a fertilizer application machine that stores a storage unit and a ground working unit.

(B) Conventional technology In general, fertilizer application machines, for example, fertilizer sowing machines, include those that evenly spread fertilizer over the field, those that inject streaks in the field, and those that inject dots at the seeding part. However, recently, in terms of fertilization efficiency and environmental protection, a method of injecting dots (hereinafter referred to as point injection) has attracted attention.

In the conventional point-feeding type fertilizer applicator, the fertilizer application part and the seed application part are fixed to the frame by bolts, respectively, so that the fertilizer application part and the seed application part cannot operate individually.

(C) Problems to be Solved by the Invention For this reason, in the fertilizer-seeding machine described above, in order to operate each fertilizer-only part or only the seeding part independently, a working part (not used) ( It is troublesome because the working part must be removed by cutting off the power of one of the fertilizer application part or the sowing part.

Further, the fertilizer sowing machine is towed by a work vehicle, for example, a rice transplanter for work in the field, but when carrying the fertilizer sowing machine in an unused state, it must be loaded on a truck or the like. However, at this time, since the fertilizer application section and the sowing section are fixed to the frame in use, loading is very troublesome.

Therefore, according to the present invention, it is possible to operate either one of the working units by folding and storing each working unit of the fertilizing and seeding machine, and also to make the fertilizing work machine compact when loading on a truck or the like. It is an object of the present invention to provide a storage device for a fertilizer application machine that can be used.

(D) Means for Solving the Problems The present invention has been made in view of the above circumstances. For example, referring to FIGS. 1 and 4, a fertilizer application unit for injecting fertilizer into a field. In a fertilizer application machine (1) having (5) and a ground work section (6) for seeding seeds or seedlings, the power from the drive section (3) is transferred via the first transmission case (21). A first shaft (15) which is transmitted to the fertilizer application section (5),
The power from the drive unit (3) is transferred to the second transmission case (49).
The second shaft (17) which is transmitted to the ground working part (6) through the first working case (21) and the first transmission case (21).
A first locking member (41) that locks the fertilizer application portion (5) at the use position of the fertilizer application portion (5) rotated downward about the shaft (15) of the Power transmission cases (49)
A second locking member (which locks the ground working part (6) at the use position of the ground working part (6) rotated downward about the second shaft (17). 71) and the first
And the second locking members (41) and (71) are released, and the first and second transmission cases (2) are provided between the locking members.
1) and (49), and a holding member (43) interposed to hold the fertilizer application part (5) rotated upward and the ground working part (6) in non-use positions. It has a feature.

(E) Action Based on the above configuration, in the fertilizer application machine (1), the power from the drive unit (3) is transmitted to the fertilizer application unit (5) and the ground work unit (6) at the use position, and the fertilizer application unit (6) is operated. In 5), fertilizer is poured into the field, and seeds or seedlings are planted in the ground working section (6).

To perform fertilization work using only the fertilizer application part (5), the second locking member (71) of the ground work part (6) is released, and the second shaft (17) is used as an axis. By rotating the ground working part (6) upward and inserting and locking the holding member (43) while the locking member (71) is released, the ground working part (6) is placed in the non-use position. And fertilizer work.

Moreover, in order to perform the seeding work using only the ground work part (6), the first locking member (41) of the fertilizer application part (5) is released, and the first shaft (15) is used as an axis. By rotating the fertilizer application part (5) upward and inserting and locking the holding member (43) while the locking member (41) is released, the fertilizer application part (5) is brought to the non-use position. Hold and carry out seeding work.

Also, remove the fertilizer application machine (1) from the work vehicle,
By holding both the fertilizer application part (5) and the ground work part (6) in the non-use position when storing them in a barn or loading them on a truck for transportation, the working machine (1) Can be stored or loaded.

(F) Effect of the invention As described above, according to the invention, the fertilizer application section (5)
Since the first shaft (15) and the ground working part (6) can rotate the second shaft (17) upward as pivots respectively, the holding member (43) can hold the shaft in the non-use position. When using either the fertilizer application unit (5) or the ground operation unit (6) of the fertilizer application machine (1) alone,
The unused device can be held in the unused state. Therefore, in the case of the single use, the device on the non-use side can be stored without disassembling and the work can be easily performed independently.

In addition, when storing or transporting the fertilizer application machine (1),
Both the fertilizer application part (5) and the ground work part (6) can be held in an unused state, and the storage or transportation work can be performed easily.

Since the locking pins 42 are inserted so that the case stopper 39 and the bracket 40 are respectively locked at both ends of the fertilizer application machine 1, the fertilizer application units 5 and 5 can be stored independently on one side of the fertilizer application machine 1.

Similar to the fertilizer application section 5 described above, the ground operation section 6 is rotated upward with the second shaft 17 serving as a support shaft, independently of one side of the fertilizer application machine 1. Since it can be stored, during fertilization and sowing work, either fertilization work or sowing work can be performed independently, and the fertilizer application section 5,
Since the work can be performed only on either the left side or the right side of the 5 and the ground working unit 6, 6, it is possible to stop the streak.

Further, when the fertilizer application machine 1 is loaded on a truck or the like and transported, by storing the fertilizer application parts 5, 5 and the ground work parts 6, 6 in an unused state, the loading operation can be performed easily.

Next, a partially modified embodiment will be described with reference to FIG.

In the embodiment shown in FIG. 9, the first pump shown in FIG.
A pump 143 is provided instead of the 110 and the second pump 111, and four stations out of the six stations of the pump 143 are the first distribution valve 1
9 and two stations are connected to the second distribution valve 20. As a result, the first distribution valve 19 is supplied with a large amount of fertilizer, the deep nozzle is applied with a large amount of fertilizer, and the second distribution valve 20 is supplied with a small amount of fertilizer, so that the shallow layer nozzle is supplied. Is configured to be fertilized less. Therefore, in the early stage of seedling growth, the roots of the seedlings absorb a small amount of fertilizer from the shallow nozzle, and when the seedlings grow further, the roots of the seedlings absorb a large amount of fertilizer from the deep nozzle. The seedlings can absorb the required fertilizer according to their growth, and the seedlings can be satisfactorily grown.

In the above embodiment, the seeding device 50 is used as the ground working unit 6.
However, the present invention is not limited to this, and it goes without saying that a transplanting device for transplanting seedlings such as a rice transplanting device may be used.
