Description

Description: TECHNICAL FIELD The present invention relates to a chemical spraying device for a rice transplanter that sprays a chemical such as a herbicide to a field as a seedling is planted.

[Conventional technology]

As the medicine spraying device of the rice transplanter as described above, a hopper for storing the medicine, a feeding mechanism for feeding the medicine from the hopper,
There is an apparatus configured to include a rotating body that scatters the delivered medicine by rotation. As a result, the seedling planting operation is performed, and at the same time, the chemicals scattered by the rotating body are sprayed on almost all the field scenes of the planting streaks.

[Problems to be solved by the invention]

The sprayed medicines are often small, light granular,
Susceptible to wind. Therefore, when the medicine is scattered by the rotating body as described above, the medicine is washed away by the wind, and the medicine is not sprayed on the desired field scene (almost all the field scenes of the planting strips). There is a case where the medicine is sprayed on the field scene of the above.

Also, a seedling planting device is located in front of the chemical spraying device, and the planting mechanism of the seedling planting device often bounces mud backward with planting of seedlings. The adhesion may cause a portion where the spraying of the medicine is hindered.

The present invention relates to a medicine spraying device of a rice transplanter, in which a planting mechanism splashes backward to adhere a mud so that a medicine is surely sprayed to a desired field scene (substantially all planting field scenes). The purpose of the present invention is to provide a configuration in which the application of the medicine is not hindered.

[Means for solving the problem]

A feature of the present invention resides in the following configuration in the above-described medicine spraying device for a rice transplanter.

(1) A hopper for storing a medicine, a delivery mechanism for delivering the medicine from the hopper, a rotating body for scattering the delivered medicine by rotation, and a medicine scattered by the rotating body for covering almost all the implanted strips. A guide member that diffuses and guides the fall to the field scene, the guide member is formed in a substantially box shape having an open lower part, and the guide member has a lower side than a lower end of a rear wall portion of the guide member. The lower end of the front wall is located.

(2) In the configuration of the above (1), the guide member is located below the straight line connecting the planting action position of the planting mechanism located below the front side of the guide member and the lower end of the rear wall of the guide member. The lower end of the front wall is located.

(3) In the configuration of the above (1) or (2), the lower ends of the front wall portion and the rear wall portion of the guide member are bent toward the outside.

(Operation)

(I) When the guide member of the medicine spraying device is formed in a substantially box shape with the lower part opened as in the feature of claim 1, the medicine scattered by the rotating body is diffused in the guide member and spreads on the inner wall of the guide member. While being guided, it is dropped and scattered over almost all the field scenes of the planting strip (desired field scene).

As described above, the medicine scattered by the rotating body falls while diffusing in a state surrounded by the guide member, so that even if the wind is blowing, the wind is blocked by the guide member, and the medicine is washed away by the wind. The situation that it is sprayed on another field scene is reduced.

When the guide member of the medicine spraying device is formed in a substantially box shape as in the feature of claim 1, the guide member itself functions as a strength member, and therefore, the guide member is formed of substantially all the planting strips (desired ones). It is not necessary to equip the guide member with many reinforcing members, even if the guide member becomes horizontally long so as to spread the drug over the field scene.

In the feature of claim 1, since the lower end of the front wall portion of the guide member is located below the lower end of the rear wall portion of the guide member, the planting mechanism located below the front side of the medicine spraying device, Even if the mud is bounced backward with the planting of the seedling, the bounced mud hits the front surface (outer surface) of the front wall portion of the guide member and does not enter the inside of the guide member. This prevents mud from adhering to the inside of the guide member and preventing the spraying of the medicine by the adhering mud.

(Ii) According to the features of claim 2, similar to the case of claim 1, it has the “action” described in the preceding paragraph (i), and in addition to this, has the following “action”. I have.

As in the feature of claim 2, a straight line connecting the planting action position of the planting mechanism located below the front side of the guide member of the medicine spraying device and the lower end of the rear wall of the guide member is set, and this straight line is set. If the lower end of the front wall of the guide member is positioned lower than the above, if the planting mechanism bounces the mud backwards as the seedlings are planted, the splashed mud further enters the inside of the guide member It will be difficult.

(Iii) According to the features of claim 3, similar to the case of claim 1 or 2, the “action” described in the preceding paragraph (i) or (ii) is provided. It has various “actions”.

In the guide member of the medicine spraying device, when rainwater adheres to the outer surface of the front wall or the rear wall, flows downward along the outer surface, and reaches the lower end of the front wall or the rear wall, the rainwater flows to the front wall or the rear wall. It may go around the lower end of the rear wall and enter the inner surface of the front wall or the rear wall. In such a state, the entered rainwater may cause the medicine to adhere to the inner surfaces of the front wall and the rear wall to form a lump, and the lump of the medicine may hinder spraying of the medicine.

Therefore, if the lower ends of the front wall portion and the rear wall portion of the guide member are bent outwards as in the feature of claim 3,
Even if rainwater adhering to the outer surfaces of the front and rear walls flows downward and reaches the lower ends of the front and rear walls, it goes around the lower ends of the front and rear walls and Since there is no such thing as entering the inner surface of the wall, if the rainwater enters the medicine, it adheres to the inner surface of the front wall or the rear wall and forms a lump, and if this lump of medicine prevents the spraying of the medicine, I have nothing to say.

〔The invention's effect〕

According to the feature of claim 1, in the medicine spraying device of the rice transplanter, the guide member is formed in a substantially box shape having an open lower part, thereby suppressing the influence of wind and supplying the medicine to almost all of the planting strips. (Desired field scene), the medicine can be efficiently sprayed, and the waste of the medicine caused by spraying the medicine to another field scene can be reduced. When the guide member of the medicine spraying device is formed in a substantially box shape, the guide member itself functions as a strength member, and it is not necessary to provide many guide members with a reinforcing member.
This is also advantageous in terms of weight reduction and simplification of the structure.

When the lower end of the front wall portion of the guide member is positioned below the lower end of the rear wall portion of the guide member as in the feature of claim 1, the mud splashed by the planting mechanism may cause the muddy soil. Is prevented from entering the inside of the guide member, thereby preventing the situation that the spraying of the medicine is hindered by the adhesion of the mud to the inside of the guide member, so that the medicine can be evenly sprayed, and the spraying of the medicine can be performed. Performance could be improved.

According to the feature of claim 2, the "effect of the invention" of claim 1 is provided as in the case of claim 1. Claim 2.
According to the feature of the above, the mud splashed by the planting mechanism is further prevented from entering the inside of the guide member, so that the spraying performance of the medicine can be further improved.

According to the feature of claim 3, the "effect of the invention" of claim 1 or 2 is provided as in the case of claim 1 or 2. According to the feature of claim 3, the rainwater wraps around the lower end of the front wall or the rear wall and enters the inner surface of the front wall or the rear wall, and the rainwater causes the medicine to form on the front wall or the rear wall. The situation of adhering to the inner surface was prevented beforehand, so that the medicine could be evenly sprayed, and the spraying performance of the medicine could be further improved.
