Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is, for example, a side-row fertilizer applicator equipped in a rice transplanter, which is a forced-feeding device of the fertilizer applicator capable of forcibly pushing fertilizer into the bottom of the working groove Regarding

[Conventional technology]

Conventionally, in a fertilizer applicator that applies fertilizer to the inside of the working groove behind the working groove, fertilizer is supplied by dropping it from above into the fertilizing trough provided at the rear of the working groove, and the fertilizer is applied to the bottom of the working groove. The structure was such that fertilizer was applied while dropping it.

[Problems to be solved by the device]

Therefore, when the fertilizer is dropped into the fertilizer trough, the fertilizer may flow out from the ditches especially in the paddy field, resulting in poor fixability and unstable fertilization accuracy.

[Means for solving the problem]

The present invention solves such a problem and enables accurate and stable fertilization. Therefore,
In a fertilizer applicator that applies fertilizer to the inside of the groove after the groove body (1), the groove body (1) communicates with the lower part of the fertilizer hopper (2) and is located at the rear of the groove body (1). 1) The feeding roll (4) is provided in contact with the rear of the feeding roll (4), a plurality of cylinders (3) are provided on the outer circumference of the feeding roll (4), and the lower part of the feeding roll (4) is the above-mentioned product. Each of the cylinders (3) is rotatably installed on the rear surface of the groove body (1) such that the height of the groove body (1) is substantially equal to that of the bottom surface of the groove body (1).
Inside the cylinder (3) at the bottom of the pay-out roll (4)
The pistons (5) are reciprocally mounted so that they can move to the tip end of the cylinder, and the opening of the cylinder (3) of the feeding roll (4) is fixed on the rear surface of the groove body (1). It is configured to cover the section.

[Action]

Therefore, while the feeding roll is rotating, the fertilizer can be received in the cylinder by the lowering of the piston in the upper part, while it can be pushed out by the piston in the lower part, and it is formed by the grooving body and somewhat hardened. It will be possible to apply fertilizer by squeezing the fertilizer into the soil at the bottom of the ditch immediately after making the ditch without time lag.

〔Example〕

 Next, an embodiment shown in the drawings will be described.

The drawing shows a side sectional view of a part of a fertilizer applicator, in which a grooving body (1) is erected at a site on the side of the float near the planting seedling in the planting part of the rice transplanter, and the grooving body is provided. A fertilizer hopper (2) is installed above the rear side of (1) to constitute a side-row fertilizer applicator of a rice transplanter.

A cylinder-shaped feeding roll (4) is rotatably driven behind the groove body (1). The groove body (1)
The front side of the pay-out roll (4) approaches the arc-shaped back surface (1a) formed in the rear part, and the upper surface of the pay-out roll (4) faces the bottom surface of the fertilizer hopper (2), and the pay-out roll (4) Cylinders (3) that are axially mounted so that the lower surface of each of them is at substantially the same height as the bottom surface of the groove body (1), and are radially released to each part of the outer circumference 4 of the feeding roll (4). ) Are formed respectively.

Inside the feeding roll (4), a rotating body (6) is mounted which is eccentric to the center of the feeding roll (4) below and rotates in the same direction at the same angular velocity as the feeding roll (4). The internal and external pistons (5a) and (5) are fitted in the cylinders (3), and the compression spring (7) is interposed between the pistons (5a) and (5). Between the pistons (5a) and each part of the outer circumference 4 of (6), each piston rod (8) of a fixed length is inserted in a swinging link manner, and the pistons (5) are arranged in the lower part. Is moved to the tip opening of the cylinder (3).

The rotating body may be an eccentric radial piston motor.

Therefore, with the machine body advancing in the direction of arrow (a) and planting is performed and the grooving body (1) is grooving on the rice field, the feeding roll (4) and the rotating body (6) are in the arrow (b) direction. When rotated at the same angular velocity as above, as shown in the figure, the piston (5) is lowered at the upper side to sufficiently accept the fertilizer in the cylinder (3), and from that state, the grooving body (1)
When rotating downward along the back surface (1a) of the cylinder, the compression spring (7) absorbs the compression force of the piston (5) against the fertilizer in the cylinder (3), and the piston (5) is pushed down. On the lower side, therefore, the elastic force of the compression spring (7) is also applied to push the piston (5) to the tip opening of the cylinder (3), and the piston (5) is formed by the groove body (1) to some extent. , Fertilizer can be applied by embedding fertilizer into the soil at the bottom of the hardened trench as shown by the arrow (c).

[Effect of device]

Thus, the present invention relates to a fertilizer applicator for applying fertilizer to the inside of the groove at the rear of the groove body (1), which is located below the fertilizer hopper (2) and located behind the groove body (1). Has
A delivery roll (4) is disposed in contact with the rear side of the groove body (1), a plurality of cylinders (3) are provided on the outer periphery of the delivery roll (4), and the delivery roll (4) is provided. The lower part is rotatably installed on the rear surface of the groove body (1) so that the lower part has a height substantially equal to the bottom surface of the groove body (1),
Inside each cylinder (3), a piston (5) is reciprocally mounted so that it can move to the tip opening of the cylinder (3) at the lower part of the feeding roll (4). 1) Since the rear surface of the feeding roll (4) covers the opening of the cylinder (3) for a certain section, the piston can be pushed down by the piston while the fertilizer is received in the cylinder by the lowering of the piston. As a result, the fertilizer can be satisfactorily fertilized by pushing it into the soil on the bottom of the groov that has been hardened by the grooving body and pushing it out immediately after the grooving without a time lag. Compared with the case where the body and the feeding roll are placed apart, the fertilizer does not flow out from the inside of the groove as in the past, but is forced to be embedded in the soil immediately after the groove and the accuracy is improved. Good and reliable and stable fertilization can be performed, and the fertilization roll (4) having the cylinder (3) rotatably provided in contact with the rear side of the grooving body (1) is arranged in a simple structure and preferably implemented. It has excellent features. In addition, since the rear surface of the grooving body is configured to cover the opening portion of the cylinder of the feeding roll for a certain period, the rear surface of the grooving body is more effective than the case where the grooving body and the feeding roll are arranged separately. It is available.
