Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planting nail of a straw transplanter, and more particularly to a technique for eliminating the inconvenience of the straw planting seedling being caught by the planting nail.

[0002]

2. Description of the Related Art A planting nail of a strawberry transplanter is disclosed in Japanese Patent Laid-Open No. 4-33.
As disclosed in Japanese Laid-Open Patent Publication No. 0210, the seedling pushing tool is provided with an upwardly open substantially U-shaped pressing portion and a bifurcated planting claw. This is the actual exploitation Sho 63-95423
This is because the structure of the planting claw of the paddy rice planting machine shown in the publication is followed by the strawberry planting machine as well. By pressing the left and right side parts of the grasped seedling with the seedling pushing tool, the posture is disturbed and It is designed so that it can be pushed out without damage.

[0003]

However, at the time of actual planting, despite the push-out action of the pushing tool, the strawberries seedlings remained in the grip groove of the planting claws, and the seedlings planted by dragging Problems such as overturning or lifting of seedlings sometimes occurred. An object of the present invention is to eliminate the above-mentioned inconvenience by making sure that the strawberries and seedlings are extruded from the grip groove by devising the structure of the planting nail.

[0004]

[Means for Solving the Problems] To achieve the above object, the present invention provides a tip-forked bifurcated planting claw provided with a grip groove for sandwiching the seedling, and a seedling sandwiched by the planting claw. And a seedling pushing tool for pushing out the seedling pushing groove from the groove. The seedling pushing tool is configured by attaching an upwardly open substantially U-shaped pressing portion to the extruding member tip, and the opening side end of the pressing portion and the gripping groove are formed. In the planting claw structure of the strawberry planting machine arranged opposite to each other, a pressing member is provided with a cleaning member having a seedling pressing portion to be inserted into the gripping groove on the rear side of the seedling sandwiched by the gripping groove. It is characterized in that the side view angle of the part is made substantially equal to the seedling plunging angle when the seedlings sandwiched by the grip grooves plunge into the field.

[0005]

In the paddy rice seedling that is a mat-shaped continuous seedling, when the seedling is extruded, the seedling portion that is not directly subjected to the extruding action is also dragged and extruded from the grip groove. However, since the Mushroom seedlings are wash seedlings that are divided into individual strains, that is, rose seedlings, unless the extrusion action is transmitted to the entire grasped seedlings, the extruding force acts on the terminal seedlings at the innermost part of the grasping groove. However, it was found that it would remain in the groove. Therefore, if the above characteristic configuration is adopted, even if there is a seedling to be left in the grip groove, it can be surely pushed out by the cleaning member that directly presses the sandwiched portion.
In addition, the side view angle of the cleaning member is almost matched to the seedling plunging angle when the seedlings sandwiched by the grip grooves plunge into the field. The posture of the attached seedlings is not disturbed.

[0006]

[Effects of the Invention] Therefore, by simply modifying the existing seedling extruding tool by adding a cleaning member, it is possible to eliminate the phenomenon that the seedlings are left on the planting nails due to the straw grass without disturbing the planting posture, and to improve the planting performance. It was possible to provide a product with the attached state.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 shows a planting part of the strawberry planting machine, where 1 is a feed case, 2 is a planting case, and 3 is a planting device. The planting device 3 is configured to include a seedling placing table 4 which reciprocates laterally with a constant stroke, a planting mechanism 5 for taking out and planting seedlings one by one from the lower end of the seedling placing table 4, a grounding float 6 and the like. ing.

As shown in FIGS. 1 to 3, the planting arm 7 provided in the planting mechanism 5 has a grip groove 8 for holding the seedlings.
It has a split bifurcated planting claw 9 and a seedling pushing device 10 for gripping the seedling sandwiched by the planting claw 9 and pushing it out from the groove 8. The seedling extruding tool 10 is configured by fixing an upwardly open substantially U-shaped pressing portion 11 formed by bending a plate material to the tip of an extruding member 12 formed of a round bar, and gripping the open side end of the pressing portion 11. Seedling extruding tool 1 with the groove 8 facing each other
0 is slid and pushed out. still,
The description of the slide driving mechanism of the seedling pushing tool 10 configured inside the planting arm 7 will be omitted for the known structure.

The rear end of the pressing portion 11 on the side of the planting claw 9 is obliquely cut, and the left and right pressing plate portions 11a, 11 are formed in that portion.
A cleaning member 13 having a V shape in a side view, which is welded across b, is provided. The cleaning member 13 is composed of a bar material, and the gripping groove 8 is provided on the rear side of the seedling sandwiched by the planting claws 9 on the upper portion thereof.
A seedling pressing portion 13A to be inserted into is formed. Further, the side view angle θ of the seedling pressing portion 13A is made substantially equal to the seedling plunging angle when the seedling sandwiched by the grip grooves 8 plunges into the field. That is, the angle θ formed between the seedling pressing portion 13A and the sliding movement direction of the extruding member 12 is defined by the angle between the culm direction of the seedling thrust into the field and the sliding movement direction of the extruding member 12 (= θ. ) To the cleaning member 13
Is installed.

[Other Embodiment] As shown in FIGS. 4 and 5, the cleaning member 13 is composed of a straight rod member, and is attached to the upper end of the pressing portion 11 whose upper edge is cut in accordance with the included angle θ. You can use the existing one. Further, as shown in FIG. 6, a cleaning member 13 made of a strip-shaped plate material along the longitudinal direction of the grip groove 8 may be fixedly attached to the upper portion of the pressing portion 11.

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