Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a rice transplanter with a fertilizer application device configured to spray fertilizer into a paddy field at the same time when seedlings are planted.

[Conventional technology]

As the rice transplanter, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 62-167515, fertilizer fed from a feeding device arranged above the planting arm is guided by dropping through a hose to produce the rice. It is sent to the ditch dug in the paddy field by a gutter.

[Problems to be solved by the device]

Since the grooving device advances while being thrust into the rice field, water may enter the hose from the grooving device, which may cause fertilizer powder to adhere to the inner surface of the hose. If such an adhesion phenomenon is left as it is, the hose will eventually become clogged with fertilizer.

Here, the present invention focuses on the above-mentioned situation and aims to construct a compact mechanism in which the fertilizer is unlikely to be clogged in the hose.

[Means for Solving the Problems]

The present invention is a rice transplanter with a fertilizer application as described above, wherein the hose is a flexible hose, and a bridging member is installed between the hose and the drive unit that repeatedly drives the planting arm up and down. This is because the hose is driven to vibrate in conjunction with the vertical movement of the arm, and the action and effect are as follows.

[Action]

With the above-described structure, the hose is constantly driven by vibration during the planting work, and the fertilizer that has adhered to the inner surface of the hose drops downward due to the shaking effect. Since the operation of the drive unit of the planting arm is used, the swing structure of the hose can be constructed by making some modifications such as arranging a bridging member on the existing structure.

As described above, by applying vibration to the hose, the adhesion phenomenon of fertilizer in the hose can be reduced, and the phenomenon that the hose is clogged with the fertilizer can be prevented. Further, since the vibration structure of the hose is a structure that fully utilizes the existing structure, it is relatively easy to construct.

〔Example〕

Hereinafter, the present invention will be described with reference to the drawings by a riding type rice transplanter.

As shown in Fig. 2, the horizontal axis of the rear part of the planting mission (1)
(P ₁ ) A pair of planting arms (3) are pivotally supported at both ends of the planting case as the drive unit (2) that is rotated around (P ₁ ), and on the guide rail (4) above the planting mission (1). The seedling planting device is configured with a seedling stand (5) that is driven to reciprocate horizontally to the left and right, and a float (6) for leveling and maintaining posture at the bottom of the planting mission (1). The planting device is connected to a traveling machine body (not shown) via a four-link mechanism (7) so that it can be moved up and down.

A fertilizer applicator consisting of a tank (8) and a feeding section (9) is supported on the upper part of the planting mission (1) by a frame (10), and a feeding roll in the feeding section (9) (Fig. The drive arm (11) for the planting mission (1) and the cam mechanism (not shown) in the planting mission (1) are interlocked with each other via the rod (12) to rotate the planting case (2). In conjunction with the rod
(12) is pushed and pulled, the feeding roll is rotationally driven, and the fertilizer in the tank (8) is fed. The fed fertilizer passes through the hoses (13a), (13b) and the grooving plate (14) and the grooving device.
In (15), it is sent into the ditch that is dug in the rice field.

Next, the vibration driving structure of the hoses (13a) and (13b) will be described in detail. As shown in FIGS. 1, 2, and 3, the feeding part (9) is fixed on the planting mission (1) by the frame (10). While the grooving plate (14) and the grooving device (15) are fixed to the float (6), the hose (13a) is installed from the feeding portion to the grooving device (15). , (13b) are made of a flexible material such as vinyl or rubber. As for the hose (13a) passing through the outside of the planting arm (3), as shown in FIGS. 1 and 2, the rotary shaft of the member (18) laid across both planting arms (3). From the horizontal axis (P ₁ ) which is the core, to the part projecting eccentrically in the direction orthogonal to the longitudinal direction of the planting case (2) and the ring member (16) fitted on the hose (13a). A bridging member (17) is installed. With the above structure, the hose (13a) is vibrated as the planted case (2) rotates.

On the other hand, as shown in FIGS. 1 and 3, the hose (1
3b) may pass near the upper side of the rotation locus of the planted soot (2), but this arranges the arrangement pitches on the left and right of the grooving device (15) connected to the hoses (13a) and (13b). Because of that. In this case, as shown in the both figures, the eccentric cam (21) is fixed to the support shaft (20) of the planting case (2), and the ring member (22) is attached to the eccentric cam (21). ) And hose (13
The bridging member (23) is provided so as to span the ring member (16) fitted onto the b) and the ring member (22). With the above structure, while giving vibration to the hose (13b),
This prevents the planted case (2) from coming into contact with the hose (13b).

[Another embodiment]

As shown in FIG. 4, the hose (13a) is fixed to the guide rail (4) by the connecting member (19), and the tip of the bridging member (17) pushes the side wall of the hose (13a) to elastically move it. The hose (13a) may be deformed to give vibration. In this case, if the side wall of the hose (13a) is elastically deformed, the fertilizer will be temporarily blocked at this part, which will cause the fertilizer to be intermittently sent downward. Of.

In the above embodiment, the rotating planting case (2) has two sets of planting arms (3), but one set of planting arms is used to plant one row of existing planting machines. It is also possible to employ a structure in which a bridging member (17) is installed across the link mechanism that drives the arm up and down and the hoses (13a) and (13b).

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the structure of the accompanying drawings by the entry.
