Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling lateral feeding device for a transplanting machine which sequentially transplants soil-bearing seedlings into ridges while running.

[0002]

2. Description of the Related Art For example, in a field transplanter for transplanting soil-grown seedlings (pot seedlings) such as vegetables, a row of soil-grown seedlings loaded in a seedling tray is pushed out at a stretch by a seedling extrusion mechanism. The seedlings are fed to the feeding device, and the seedlings are fed one by one to the planting cylinders that are vertically stabbed into the ridges, and the seedlings are sequentially transplanted to the ridges. I am trying to keep going.

Conventionally, the above-mentioned seedling lateral feeding device has an endless chain that advances in a fixed direction arranged vertically, and a large number of seedling receiving trays that receive soil-grown seedlings are provided on the outer peripheral portion of the chain so as to intersect the traveling direction of the chain. The guide rails are arranged in a row so that they can swing freely in the direction in which the guide rails come into contact with the lower surface of each seedling receiving tray advancing with the chain and maintain their postures. The rail is formed with a straight line portion for horizontally holding each seedling receiving tray and a step portion for tilting the seedling receiving tray from the horizontal state to the inclined state (see, for example, Japanese Patent Application No. 5-48267).

[0004]

In the conventional seedling lateral feeding device, a guide rail for supporting one end of the seedling receiving tray is arranged, and the tray is moved by a winding spring provided at a pivotal support portion between the seedling receiving tray and the chain. It is biased to the tilt side and slidably contacts the guide rail. Therefore, the guide rail holds each seedling receiving tray horizontally by the straight portion at the extruding position of the soiled seedlings against the biasing force of the winding spring, but each seedling receiving tray reaches above the planting tube. Then, the seedling receiving tray falls into the stepped portion of the guide rail and tilts by the biasing force of the winding spring.

However, conventionally, the step portion is formed by notching the guide rail midway, and the tilting of the seedling receiving tray when it falls into the step portion of the guide rail is too rapid. There was a case that the direction of the plant changed and it could not be properly supplied to the planting cylinder, or the soil seedlings collapsed due to the vibration when the tray was tilted, which was the cause of the stock stall.

Further, in the past, since the seedling receiving tray was tilted only by the biasing force of the winding spring, when the soil was caught in the winding spring, the biasing force was weakened and the tray could not be tilted reliably. . In view of such circumstances, an object of the present invention is to gradually tilt the seedling receiving tray so as to prevent the stocked seedlings from running out.

Another object of the present invention is to ensure that the gradual tilting of the seedling receiving tray can be performed without depending on the spring force.

[0008]

In order to achieve the above object,
The present invention has taken the following technical means. That is, the present invention, the annular body that advances in a certain direction is arranged in a vertical direction, in the outer peripheral portion of this annular body, a large number of seedling receiving trays that receive soil-grown seedlings in a direction that intersects the traveling direction of the annular body. Arranged so as to be swingable, on the side of the annular body, a guide rail that abuts on the lower surface of each seedling receiving tray advancing together with the annular body to maintain its posture is provided, and on this guide rail, In a seedling lateral feeding device of a transplanter in which a straight portion that horizontally holds each seedling receiving tray and a step portion that tilts from this horizontal state to an inclined state are formed, the step portion of the guide rail advances the annular body. It is characterized in that it is inclined so as to be gradually displaced toward the tilting side of the seedling receiving tray as it goes in the direction.

In this case, for the reason described below, the guide rail is composed of a first guide rail slidingly contacting one end of the seedling receiving tray and a second guide rail slidingly contacting the other end of the seedling receiving tray. , Inclining the stepped portion of the first guide rail so that it gradually displaces downward as it goes in the traveling direction of the annular body, and push the other end side upward so that the seedling receiving tray tilts along this stepped portion. Therefore, it is preferable to incline the stepped portion of the second guide rail so as to be gradually displaced upward in the traveling direction of the annular body.

Further, it is preferable to provide an extruding member on the upper surface of each seedling receiving tray, which moves in the inclination direction when the tray is tilted and slides down the seedlings with soil.

[0011]

In the present invention, since the stepped portions 75b and 76b of the guide rails 75 and 76 are inclined so as to be gradually displaced toward the tilting side of the seedling receiving tray 65 as the annular body 60 advances, the seedling receiving trays are inclined. As the tray 65 advances with the annular body 60, the stepped portions 75b and 76b of the guide rails 75 and 76 gradually tilt the seedling receiving tray 65.

According to the second aspect of the present invention, the second guide rail 76 slidably contacting the other end of the seedling receiving tray 65.
Since the stepped portion 76b pushes up the other end side of the tray 65, the seedling receiving tray 65 can be surely tilted even if soil is attached to the pivotally attached portion of the tray 65. On the other hand, when the seedling receiving tray 65 is gradually tilted as described above, the soil-bearing seedling B may be less likely to slip off the seedling receiving tray 65 due to the frictional resistance.

The invention as set forth in claim 3 eliminates such inconvenience, and the pushing member 69 provided on the upper surface of the seedling receiving tray 65 moves in the tilt direction when the tray 65 tilts, and the seedlings with soil. Since B slides off, seedling receiving tray 65
Even if the rice seedlings tilt gradually, the soil-bearing seedlings B are surely dropped onto the planting cylinder 42.

By holding the pushing member 69 in the position setting posture 69a by the holding means 79 (the straight line portion 76a), the earthed seedling B can be uniformly placed on the seedling receiving tray 65 at the optimum position. This pushing member 69 is pushing posture 6
It is possible to prevent the posture from being changed to 9b and prevent the soiled seedling B from being accidentally pushed out.

Further, when the seedling receiving tray 65 is tilted at a required position, the pushing member 69 is forcibly changed to the pushing posture 69b by the operating means 80, so that the pushing member 69 places it on the seedling receiving tray 65. The soil-embedded seedlings B thus formed can be forcibly slid off, and the occurrence of defective supply to the planting device 32 can be prevented. 11 and 12 show a second embodiment of the present invention.

In this embodiment, the attitude of the seedling receiving tray 65 is controlled by the guide rail 75 provided on the tilting side (left side).
This is performed by a winding spring 86 that biases the seedling receiving tray 65 so that the left side is inclined downward.
The coil portion is fitted over the connecting shaft 68, one end of which is engaged with the bracket 67 and the other end of which is engaged with the connecting piece 66. Therefore, the inclined portion 75b for gradually inclining the seedling receiving tray 65 is formed only on the left guide rail 75.

Between the protruding portion 72 of the pushing member 69 and the connecting piece 66, the pushing member 69 is tilted (left side in FIG. 11).

Therefore, when the seedling receiving tray 65 is moving along the straight portion 75a of the guide rail 75, the protruding portion 72
Is hooked on the straight portion 76a of the right guide rail 76 (FIG. 11 (a)). After that, when the seedling receiving tray 65 reaches the stepped portion 75a of the guide rail 75, the protruding portion 72 causes the protruding portion 72 to the right guide rail 76. The pushing member 69 is pushed to the pushing position 69b by the biasing force of the winding spring 86.

Then, when the seedling receiving tray 65 is reversed and moved in the backward direction, the projecting portion 72 is caught by the starting end portion 77a of the right guide rail 76, and the pushing member 69 is pushed by the cam portion 77c of the guide rail 76. Thus, it returns to the position setting posture 69a against the biasing force of the winding spring 86. FIG.
14 and FIG. 14 show a third embodiment of the present invention.

In this embodiment, the pushing member 69 is not provided, but a pair of left and right guide rails 75 and 76 are provided. Among them, the right guide rail 76 is provided with a step portion 76b that is inclined so as to be gradually displaced upward as it goes in the traveling direction of the annular body 60. This step portion 76b is a seedling receiving tray. When 65 is tilted along the stepped portion 75b of the left guide rail 75, the other end side (right side) is pushed upward.

In this case, a winding spring for biasing the seedling receiving tray 65 in the anti-tilting direction (the direction in which the right side in FIG. 14 is lowered) is provided at the pivotal portion of the seedling receiving tray 65, and the anti-tilting side of the tray 65 is If only the right guide rail 76 is slidably contacted, the left guide rail 75 can be omitted.
