Description

[Detailed description of the invention] [Industrial field of application] The present invention includes a seedling lifting prevention stay that can contact and prevent the placed seedlings from lifting up, on a seedling stand that is tilted and moves back and forth in the left and right direction. , relates to a seedling planting device of a rice transplanter, which is provided along the inclination direction of the seedling stand.

[Conventional technology]

In this type of seedling planting device, as shown in FIG. 4, the bottom plate 6a of the seedling stand 6 is bent into a plurality of concave and convex shapes along the inclination direction, and the convex portion 6b of the bottom plate 6a is bent. The upper surface forms a seedling placement surface.

[Problem that the invention attempts to solve]

In the case of this conventional device, the contact area between the seedling mounting surface of the seedling mounting table 6 and the mounted seedlings A is minimized,
Although the sliding performance of the placed seedling A toward the seedling take-out port side can be improved, the leaf portion of the seedling A is in a state where the stays 13 provided to prevent the placed seedling from coming into contact with each other are dense. Since it is easy to get caught on the leaf part b of the seedling, it not only damages the leaf part b of the seedling, but also causes the problem that this catching acts as a brake, making it impossible to improve the sliding condition as a whole.

The purpose of the present invention is to improve the above-mentioned problems by making simple modifications to the seedling stand.

[Means to solve the problem]

A characteristic configuration of the seedling planting device according to the present invention is that a protruding strip is provided on the upper surface of the convex portion of the bottom plate at a location directly below the seedling lifting prevention stay, and protrudes above the seedling placement surface of the convex portion. Its functions and effects are as follows.

[Effect]

By lifting a part of the placed seedlings with a convex strip formed on the upper surface of the convex part of the bottom plate of the seedling platform,
It is possible to reduce the frictional resistance between the seedling placement surface and the placed seedlings, and also to reduce lateral displacement of the placed seedlings. Furthermore, since the protruding stripes for this purpose are formed directly below the seedling lifting prevention stay, the leaf groups of the seedlings are divided into left and right sides due to the lifting action of these protruding stripes, and this divided V-shape Since the seedling lifting prevention stay is located within the shaped space, it is possible to suppress the stay from getting caught on the leaves of the seedling.

[Effect of idea]

Therefore, it is possible to improve the effect of preventing the placed seedlings from sliding sideways and to suppress damage to the seedlings by making a simple improvement by forming the above-mentioned convex stripes on the seedling stand. It has now become possible to ensure the sliding supply of seedlings to the seedling outlet side.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

The seedling planting device of the riding type rice transplanter shown in Figs. 1 to 3 is constructed.
This is a transmission case that is driven from the transmission case 1 through a transmission shaft 2, and a pair of left and right planting cases 3, 3 extend rearward from this transmission case 1, and a pair of left and right planting cases 3, 3 at the rear of the planting cases 3, 3 are connected to each other. A drive mechanism 5 for forcing the planting claws 4 to perform a forced circulation movement is provided on each side.

Reference numeral 6 denotes a seedling stand with an inclined position relative to the ground, on which a plurality of pine-shaped seedlings A can be placed horizontally in parallel and movable back and forth in the left-right direction. The rail 7 that slides and guides the lower ends of the group of seedlings A is formed with seedling take-out ports 8 at predetermined intervals in the left-right direction.

The bottom plate 6a of the seedling stand 6 is bent into a plurality of concave and convex shapes along its inclination direction, and the upper surface of the convex portion 6b of the bottom plate 6a forms a seedling placement surface.

Reference numeral 9 denotes a seedling vertical lever which is operated near the lower end of the slope of the seedling tray 6 and is operated every time the seedling tray 6 is located at the end of the reciprocating path to forcibly transfer the placed seedlings A to the side of the seedling take-out port 8. It is a feeding device.

The feed pawl 9a of the seedling vertical feeding device 9 using a star wheel has a braking force that acts to feed the seedlings vertically when the seedling platform 6 is located at the end of the reciprocating path, in other words, while allowing intermittent rotation. A band brake 10 is provided, and the operated arm 10a of the band brake 10 and a clutch lever 11 for turning on and off the planting clutch 16 provided on the passenger aircraft side are linked by a wire 12, and the clutch is The band brake 10 is switched to the brake release state in conjunction with the clutch disengagement operation of the lever 11, and the band brake 10 is switched to the brake state in conjunction with the clutch engagement operation.

As a result, seedling replenishment work can be carried out smoothly without being interfered with by the vertical seedling feeding device 9, and the brake release operation for this purpose also utilizes the cutting operation of the planting clutch, which is an essential operation when replenishing seedlings. This can be done easily.

Reference numeral 13 denotes a seedling lifting prevention stay that extends along the inclination direction of the seedling rack 6, and allows the seedling to be placed by swinging around the horizontal axis relative to the bracket 14 fixed to the side frame 6c of the seedling rack 6. It is configured so that it can be freely switched between an active position in which it is located close to the upper surface of the bed soil a of the seedlings to prevent the seedlings A from floating, and a non-active position in which it is spaced backward and upward from the upper surface of the bed soil a of the seedlings A. There is.

Reference numeral 15 denotes a convex portion 6b of the bottom plate 6a of the seedling stand 6, located directly below the seedling lifting prevention stay 13.
This is a convex strip that is integrally formed on the upper surface of the convex portion 6b so as to protrude upwardly from the seedling placement surface on the upper surface of the convex portion 6b.

By lifting a part of the placed seedlings A with the convex shape 15 formed on the seedling placement table 6, the frictional resistance between the seedling placement surface and the placed seedlings A can be reduced, and the It is also possible to reduce sideways displacement of the seedlings. Moreover, the protrusion 1 for this purpose
5 is formed directly below the seedling lifting prevention stay 13, the lifting action of the ridge 15 divides the leaf part b group of the seedling A into left and right parts, and this divided V-shaped space Since the seedling lifting prevention stay 13 is located within S, it is possible to prevent this stay 13 from getting caught on the leaf part b of the seedling A.

Next, another example will be described.

(a) The protruding strip 15 may be constructed from a member different from the seedling stand 6.

(b) The protruding strip 15 may be configured to have either a hollow shape or a solid shape.

(C) The cross-sectional shape of the protruding strip 15 is not limited to the rectangular shape of the above embodiment, but may be semicircular or polygonal.
