Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice transplanter equipped with a fertilization device, which is configured to be able to perform fertilization work as well as commercial work by cutting trenches near the site where seedlings are planted.

Conventionally, in the rice transplanters mentioned above, fertilizer remains attached to the trenching tools due to water and moisture adhering to the trenching tools, or clogging occurs due to this adhesion, resulting in insufficient fertilizer supply to the field. In some cases, fertilizers were not supplied to the fields.

Therefore, if the guide path of the groove-cutting tool is made larger in diameter to avoid clogging or insufficient supply even if fertilizer adheres to it, the width of the groove-cutting tool will become larger and the groove-cutting tool will Due to the intense mud pushing, the planted seedlings were prone to tilting due to the fluid muddy water or toppling over.

An object of the present invention is to prevent poor fertilization due to fertilizer adhesion while minimizing mud pushing by the groove cutting tool.

The characteristic configuration of the present invention is that in a rice transplanter with a snow-covered fertilization device, the extrusion tool for the fertilizer facing directly into the trench can be freely driven up and down in a state where it cleans the trench and descends to the vicinity of the lower end of the trench tool. The functions and effects are as follows.

That is, even if the fertilizer adheres to the groove-cutting tool, the push-out tool descends along the groove-cutting tool to near the lower end of the groove-cutting tool to reliably scrape off the adhering fertilizer. Therefore, it is possible to prevent fertilizer from remaining attached to the groove-cultivating tool, and as a result, even if the fertilizer guide path of the groove-cultivating tool is made small in diameter, clogging caused by the adhering fertilizer can be prevented. By making the groove-cutting tool smaller, it was possible to prevent mud pushing as much as possible, and moreover, it was possible to reliably supply a predetermined amount of fertilizer.

Embodiments of the present invention will be described below based on the drawings.

As shown in Figures 1 and 2, a five-row type seedling planting device (3) is installed at the rear of the wheeled traveling body via a link mechanism (2) that can be freely oscillated by a hydraulic cylinder f+l. are connected so that they can be raised and lowered freely, and are configured so that power is transmitted from the traveling body to the seedling planting device (3), and the granular fertilizer stored in the tank (4) is supplied near each seedling planting point. A fertilization device is attached to the seedling planting device (3), so that 5 rows of seedlings can be planted and fertilized.
) and a mat-like fertilizer on the seedling stand (5), the riding rice transplanter is equipped with a fertilization device that can be used to simultaneously perform sowing and fertilizing operations. be.

To configure the fertilizer application device, as shown in FIGS. 2 and 8, five fertilizer delivery devices are attached to the bottom of the fertilizer tank (4).

One rotating shaft (7) that drives these feeding devices (6)
The seedling planting arm (9) is movably connected to the transmission case via the link mechanism (8), and is interlocked and connected to the swinging link Qtl, which is the feeding device tel. (6 m) is configured to be driven in conjunction with the seedling planting arm (9), and the feeding device (6)...
Five gutter-like groove tools H, each of which has its upper end connected in communication with the five hoses (1 hose), each extending separately from the hose to form a fertilizer supply path, are connected to these groove tools α. With the opening of the pier facing towards the rear of the aircraft.

Seedling planting arms (9) are placed side by side on the sides of the machine, one on each side, and a platen) (14a)
) is attached to the ground float H through the machine, and as the aircraft travels, each of the cutting groove wheels cuts a groove near the point where seedlings are planted, forming a groove in which fertilizer is supplied from the hose by descending under its own weight. I would like to provide guidance to you.

The groove-making tool (Figs. 2 and 8)
As shown in the figure, the extruder for the fertilizer supplied to the trenching tool is extended from the seedling planting arm (9) and moved up and down in conjunction with the seedling planting movement of the seedling planting claw (9a). When the groove is driven downward, the extending end reaches near the lower end along the groove-making tool.
It is configured to scrape off fertilizer adhering to the groove cutting tool H.

FIG. 4 shows another embodiment of the groove-cutting tool (1'4), which is provided with a pair of swinging single wheels made of an elastic material and forming an on-off valve for receiving fertilizer supplied from the hoe 702. These swinging pieces θ are moved downwardly by the pushing tool (1).
It is configured to be pressed open by 19 to allow the received fertilizer to flow down, and is configured to return to the closed state by elastic restoring force after passing the extruder (l@), as shown in Fig. 2. In contrast to the groove-cutting tool α field shown in FIG. 8, which supplies fertilizer continuously, it is configured to supply fertilizer intermittently.

Extending the extrusion tool 0@ from the seedling planting arm (9) is advantageous because the structure for scraping off adhering fertilizer can be simplified in terms of the drive system. A configuration in which it can be freely attached may also be adopted.

Further, the present invention can also be applied to a walking type rice transplanter.
