Description

[Detailed Description of the Invention] The present invention maintains the positional relationship between the planting locus and the groove-cutting locus in a curved state in a prone position as close as possible to the state in straight forward motion, so that planting seedlings can be In order to ensure that fertilization work is carried out in a positionally appropriate manner (14), specifically, a trencher with a roughly V-shaped or U-shaped cross section with an opening to the rear is placed just before the planned planting site. At the same time, it is placed on the side and fixed to the float, and at the upper end of the furrower, it is placed in an inclined position from two sides to the front and downward. The present invention relates to a rice transplanter with a fertilizing device.

A4 above! In the conventional rice transplanter equipped with a fertilizer applicator, during operation, the f end of the downflow pipe, which is positioned to restrict the fall position of the fertilizer to the opening of the furrower as much as possible, is Qi1.
There was a drawback that the opening of the Kisaku ditch was blocked by accumulated soil, making it difficult for the fertilizer to come out or not to come out at all.

In particular, when the machine stops, the above-mentioned soil-blocking is likely to occur, and when the worker restarts work, he or she notices that the fertilization work has not been carried out, or the worker notices this and restarts the work once. Because of this, there was a risk of a significant drop in work efficiency.

In view of such circumstances, the present invention has an object to provide a device that can always perform reliable fertilization work by making simple modifications.

The characteristic structure of the field 101m equipped with a fertilization device according to the present invention, which has been made to achieve the above object, is that the lower end portion of the fertilization downstream pipe is provided at an appropriate distance rearward than the rear end edge of the opening of the f'F-Wlj device. The point is that a downward facing fertilizer fall opening is formed in a state where the fertilizer is placed at a distance from the outside.

The effects of the present invention having such a characteristic configuration are as follows.

In other words, even if there is soil accumulation in the rear opening of the trencher, the downward fertilizer fall opening formed at the lower end of the flow pipe is less affected by the soil than the rear edge of the opening. Since it is located at an appropriate distance rearward, if there is no accumulation of soil in the rear opening of the trencher, the fertilizer will fall due to its inertial force and fall to the inner periphery of the drop pipe facing the fertilizer drop opening. It collects on the surface and falls to the above-mentioned regulated falling point,
On the other hand, even if the lower end of the flow-down bin is blocked by soil, the fertilizer will fall from the fertilizer drop opening slightly behind the 611 regulation drop point, and in any case, the fertilizer application trajectory will be the same. The work can now be carried out reliably and without leaving any fertilization residue, with no fertilization coming off in the lateral direction, and with the falling point confined to a narrow area close to each other.

Embodiments according to the configuration of the present invention will be described below with reference to the drawings.

As shown in Figure 1, a link mechanism is attached to the traveling aircraft (not shown).
In the fertilization device installed in the seedling planting device of a riding rice transplanter, which has a transmission case H that can be freely operated via a transmission case H, a granular fertilizer receiving device is placed in the lower part of the fertilizer storage tank fIl in the direction of the axis of rotation. A rotary body for feeding fertilizer (with a concave groove (4) for
2) is fitted into a groove on the rotating shaft (3), and a fertilizer dispensing case 2) which also serves as a rotating body storage case is attached to the tank fi+.

As shown in Figures 2 to 4, the seedlings are fixed to the float (5) at the side immediately in front of the planned planting area using the planting claw (4) which is driven in circulation up and down. When the trencher (6) has an opening (6a) to the rear, the cross section is approximately V-shaped and U-shaped. A pipe (7) is provided, and the lower end portion of the downstream pipe (7) is arranged in an inclined position from the rear upper side to the front lower side of the groove cutter (6), so as to face the upper end portion of the groove cutter (6). It's not true. At the lower end portion of the fertilization flow pipe (7), the crop m' is positioned an appropriate distance behind the rear edge (6b) of the opening (6a) of the container (6), ``A downward-facing one-bag feed bank lower opening (7a) is formed.

In the figure, (8) is a top plate having a semicircular cross-sectional acting part, and is attached to both side plates (9a ), (
A pivot shaft (101) passing through the U-shaped side plates (9a) and (L+) in the inner side 0II is provided,
A rod-shaped member (8a) is fixed through the pivot shaft (lO) from a direction perpendicular to the axial direction thereof, and the other end is fixed to the soil covering plate (8) to form the soil covering plate (81). A flat plate having a plurality of holes (lla) is fixed to the shaft end of the pivot shaft (lO), and 7 rings α are attached between the holes (lla) and the groove creator (6). The soil covering plate (8) is forced into the action 11111 by interposing a row, and the hole (ll) is
The biasing force can be adjusted by changing the relationship to a). Further, as shown in FIG. 5, the rod-shaped member (8a) is attached to the pivot shaft (
10i, so the pivot shaft (1o)
There is no need for a mechanism to prevent it from coming off in the lateral direction. As shown in FIGS. 6 and 7, the cross-sectional shape of the soil covering plate (8) changes from a groove shape to a semicircular shape as it goes toward the rear, so that the soil covering shape is formed as shown in the figure. The arched part can prevent fertilizer from flying out.

As shown in Fig. 2, the tip (12g) of the foreign matter separation tool (121) identified in the groove creator (61) is set in the bottom of the resin float (5) so that it is bitten into the gap between the two. Constructed to prevent contaminants from entering.
