Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter for spraying a herbicide which enables simultaneous planting of seedlings in a paddy field and weeding.

[0002]

2. Description of the Related Art Generally, weeding in paddy fields is carried out by manually spraying a herbicide at the time of scratching and after rice planting. However, if the herbicide was sprayed at the time of scratching as described above, then the herbicide dissolved in the water would be washed away when the water was dropped for rice planting, which would cause pollution problems. At that time, the herbicide film formed on the water surface of the field may be destroyed, so that the efficacy of the herbicide may decrease. Therefore, it has been proposed to spray a herbicide at the same time as rice planting.

[0003]

However, in this case, since the herbicide is directly applied to the planted seedlings, there is a drawback that the planted seedlings are damaged by the herbicide. The present invention has been made by paying attention to the above circumstances, without impairing the medicinal effect of the herbicide, and while reducing the pollution problem, the adverse effect of the herbicide on planted seedlings does not occur. To aim.

[0004]

[Means for Solving the Problems] That is, a feature of the present invention is to provide a seedling planting device for cutting out a planted seedling from a mat-shaped seedling placed on a seedling stand and planting it in a field, and the seedling planting. A device for spraying the herbicide on the field in the rear of the device, and a device for spraying the herbicide attached to the planted seedlings behind the herbicide spraying device is provided, and its action and effect are It is as follows.

[0005]

While the seedling planting device is planting the seedlings in the field, the herbicide can be sprayed on the planted seedlings by the herbicide spraying device. After that, the herbicide adhering to the planted seedlings can be brushed off by a brushing tool.

[0006]

EFFECTS OF THE INVENTION By spraying a herbicide at the time of rice planting, there is no drop of water thereafter, so that the herbicide is not drained to a river or the like, and pollution problems are less likely to occur. The effect of the herbicide can be fully exhibited without impairing the medicinal effect of the herbicide because it moves to destroy the membrane of the herbicide. Moreover, by removing the herbicide immediately after planting from the planted seedlings, there is little effect that chemical damage such as wilting of the planted seedlings occurs.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a plant A for planting seedlings at the rear of the riding type vehicle body.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a riding type rice transplanter capable of performing fertilization and spraying herbicides simultaneously with planting seedlings in a paddy field.

[0002]

2. Description of the Related Art As a conventional riding type rice transplanter, for example, as disclosed in Japanese Utility Model Laid-Open No. 62-42719,
A fertilizer application device having a fertilizer feeding mechanism is provided above the seedling planting mechanism of the seedling planting device connected to the rear part of the riding type traveling vehicle body, and the fertilizer feeding mechanism is driven in conjunction with the seedling planting mechanism. Such a configuration is known, and has been put to practical use as a rice transplanter effective for labor saving.

[0003]

As a work incidental to the rice planting work, there is a spraying work of a chemical such as an initial herbicide in addition to the fertilizing work mentioned above, but the herbicide dissolves on the mud surface of the field and is interrupted. It is necessary to spray the herbicide so as not to adhere to the roots of the seedlings to form a uniform drug film layer. The spraying process is carried out as a matter of course, and a great deal of labor and time was spent for that purpose. Further, when the herbicide is sprayed by a dedicated spraying device, the scattered herbicide may sprinkle on the worker, so that the worker is obliged to wear a mask and clothes that do not show skin.

The present invention has been made in view of such a situation. In addition to fertilizer application and herbicide application at the same time as rice planting work, it is possible to perform good and hygienic application of fertilizer and herbicide. It is an object of the present invention to make it easy to replenish the agent and to make the structure relatively simple.

[0005]

[Means for Solving the Problems] The technical means of the present invention taken to achieve the above-mentioned object is, in a riding type rice transplanter,
A seedling planting device is connected to the rear part of the passenger traveling vehicle equipped with the driver's boarding section, a fertilizer application device is provided on the rear side of the seedling stand of this seedling planting device, and a herbicide spraying device is provided behind the fertilizer application device. The fertilizer applicator and the herbicide spraying device are arranged so that the respective feeding mechanisms of the fertilizer applicator and the herbicide spraying device are interlocked with the seedling planting mechanism of the seedling planting device, and the fertilizer hopper and the herbicide sprayer of the fertilizer applicator are provided. The hopper is disposed at substantially the same height, and the height of the herbicide spraying position of the herbicide spraying device is set to a height position lower than the upper edge of the seedling stand. .

[0006]

The operation of adopting the above technical means is as follows. (A) That is, when the seedling planting mechanism is activated and seedling planting is being performed, the feeding mechanisms of the fertilizer application device and the herbicide spraying device behind it are driven in conjunction with the seedling planting mechanism. Then, when the operation of the seedling planting mechanism is stopped by disengaging the planting clutch or the like, in synchronism with this, the feeding mechanism of the fertilizer applying device and the herbicide spraying device both stop. (B) The herbicide spraying device is on the rear side of the seedling stand of the seedling planting device provided at the rear of the traveling body on which the operator is boarding, and behind the fertilizer applying device, and ,
The spray height is also lower than the upper edge of the seedling stand.
That is, the spraying position is set at a lower rearmost position far from the operation position. Therefore, the location of herbicide application should be
The spraying height should be set so that it is far from the operator's position in the distance and there is a shield such as a seedling rest and fertilizer in the middle, and the shielding effect by the shield works effectively. Therefore, there is little possibility that the herbicide scattered by the wind or the like may reach the operator on the traveling vehicle body. (C) Since the fertilizer hopper of the fertilizer and the hopper of the herbicide spraying device are arranged at substantially the same height, fertilizer and replenishment of the herbicide can be performed by using a bag or container containing the fertilizer or the herbicide. It can be lifted to height and performed in an equivalent procedure. At this time, if there is a large difference between the heights of both hoppers,
When replenishing the hopper on the lower side, the hopper on the higher side, which is located close to the hopper, may be in the way and it may be difficult to perform the replenishing operation, but in the present invention, the heights of the both hoppers are set to substantially the same height. By doing so, such an inconvenience can be avoided in advance. In addition, by setting the height of both hoppers to an appropriate height for replenishing fertilizers and herbicides, check the contents of each hopper during replenishment and inspection of contents during work. Work can be done from the same level of eyes. Therefore, with a different line of sight for each hopper, e.g.
It is easy to check the contents more accurately.

[0007]

INDUSTRIAL APPLICABILITY According to the present invention, both fertilization and herbicide spraying can be performed at the same time as the rice planting operation, so that the operation can be performed efficiently and the following effects are brought about. That is, [1] The herbicide spraying point is set at a low position at the rear end of the machine, the seedling stand and fertilizer application device in the middle are used as a shield, and the distance from the operator's position is increased. Since it can be effectively used as a means, it is easy to avoid the scattering of the herbicide to the operator position on the riding vehicle body, and it is easy to perform the work in a hygienic working environment. [2] By placing the fertilizer hopper and the herbicide hopper at approximately the same height, there is no significant difference in height between adjacent hoppers, so the higher hopper supplies the lower hopper. It does not hinder work. Therefore, fertilizer and herbicide replenishment can be easily done at comparable levels without being hindered by the presence of adjacent hoppers. In addition, by setting the height of both hoppers to the appropriate height for replenishment of fertilizer and herbicide, it is possible to check the contents of each hopper at the time of replenishment and inspection of contents during work This is also advantageous in that the work can be easily confirmed with the same level of eyes with high accuracy. [3] Since the fertilizer and the herbicide spraying device are driven synchronously in conjunction with the seedling planting mechanism, unnecessary feeding of the fertilizer and herbicide spraying without the seedling planting operation may occur. To reduce waste of fertilizers and herbicides, and also contribute to environmental protection.
