Description

[Detailed description of the invention] [Field of industrial application] The present invention is a riding rice transplanter in which a seedling planting device equipped with a forward-leaning seedling stand that moves back and forth from side to side is connected to the rear of a passenger vehicle so that it can be raised and lowered. Regarding the seedling placement structure of the machine.

[Prior art]

Conventionally, in the seedling mounting structure of this type of riding rice transplanter, the passenger vehicle body is equipped with a spare seedling stand, and the spare seedlings are once placed on the stand, and then the planting operation is carried out. The construction is such that an operator takes out the pine-shaped seedlings along with the scooping plate from this preliminary seedling stand and places them on a predetermined location on the seedling stand.

[Problem that the invention attempts to solve]

The disadvantage of the conventional method is that while planting, it is necessary to transfer the spare seedlings from the preliminary seedling stand to the seedling stand, which not only makes the work cumbersome, but also requires transferring the pine-shaped seedlings from the scooping board. The task of replenishing the seedlings by sliding them onto the seedling tray had to be carried out with the proximal side of the scooping board lifted in line with the inclined position of the seedling tray, which made the working position cramped and was not easy. . Moreover, since the intermediate process of transferring the preliminary seedlings prepared on the ridge to the seedling tray includes the step of temporarily placing them on the preliminary seedling tray.
This required extra work and made the work itself complicated.

The purpose of the present invention is to provide a plant with a simple structure that has the function of a preliminary seedling stand, but which definitely eliminates the drawbacks of the conventional structure through rational structural improvements.

[Means to solve the problem]

The characteristic configuration of the present invention is that a scooping plate for pine-shaped seedlings is removably attached to a support member provided on the upper part of the seedling stand, and the scooping plate locked to the support member is held in a substantially horizontal position. The scoop plate supporting posture of the support member is configured to be changeable so as to be switchable to an inclined posture protruding from the upper end along the seedling stand, and when the scoop plate is in a substantially horizontal posture,
The scooping plate is received and supported by the support member and the upper end of the seedling stand, and its effects are as follows.

[Effect]

In other words, by attaching and detaching the scooping plate to the support member extending from the seedling stand, it is possible to form a substantially integral connection structure between the seedling stand and the spare seedling stand, and the stand There is no need to further transfer the seedlings to the seedling stand once they have been placed on the preliminary seedling stand, and the work process can be shortened. Moreover, since the supporting position of the scooping plate can be changed, when replenishing the seedling stand, the position of the scooping plate can be changed from a horizontal position to an inclined position with a simple operation using the changing structure of the device itself. Compared to conventional methods that require the worker to manually lift the rake board to the hand side, the work burden on the worker can be significantly reduced, and even during planting work. It has now become possible to easily supply the seedlings. Furthermore, since the horizontal position of the scoop plate is maintained by effectively utilizing the seedling stand, a dedicated holding mechanism is not required and the structure does not become significantly complicated.

[Effect of idea]

A rational arrangement in which a spare seedling stand, which skillfully utilizes a scooping board, is connected to the seedling stand,
By providing the scooping plate with a posture change function, the work burden on the worker can be significantly reduced, and a simple structure that is useful in this type of rice transplanter for single-person work is provided. I was able to do that.

〔Example〕

As shown in FIG. 1, a planting feed case 3 is provided at the rear of a passenger vehicle body 2 equipped with a driver's seat 1, a planting case 4 extends rearward from this feed case 3,
A planting mechanism 6 equipped with a planting claw 5 at the tip of the planting case 4, and a forward-slanted seedling platform 8 that places pine-shaped seedlings 7 in front of the planting mechanism 6 and moves back and forth from side to side. , and a seedling planting device A equipped with a grounding float 9 is connected to a swinging link 22 on the vehicle body side so as to be movable up and down to constitute a riding rice transplanter.

To explain the seedling stand 8 in detail, a horizontal feed shaft 10 is attached to the feed case 3, and its left and right ends are connected to the feed case 3.
The seedling stand 8 is supported on a sliding rail 12 and the left and right protruding ends of the horizontal feed shaft 10 are interlocked via a bracket 11. connect, connect,
The seedling platform 8 is configured to be reciprocated from side to side by the reciprocating movement from side to side along with the planting movement of the transverse feed shaft 10.

To explain in detail the seedling feeding device equipped on the seedling table 8, pulleys 14a and 14b are disposed on the upper and lower sides, and a wide endless belt 15 with protrusions is wound around the upper and lower pulleys 14a and 14b.
b is set to the drive side, and the pine-shaped seedlings 7 are configured to be able to be driven and moved to the seedling take-out port at each end of the horizontal movement stroke of the seedling table. A detection switch 23 is provided, and reserve seedlings are supplied based on the detection result of this switch 23.

As shown in FIGS. 1 and 2, a scooping plate 1 for pine-shaped seedlings 7 with an angle portion 16 protruding from the lower surface.
The support member 1 of the angle part 16 is placed on a seedling stand 8 which has an annular support member 19 pivoted to a bracket 18 projecting from the upper rear surface so as to be vertically swingable around a horizontal axis.
It is attached via a structure that can be freely connected to and detached from 9.

The distal end side of the scooping plate 17 latched to the support member 19 is supported by the seedling platform 8, and the distance from the proximal end of the scooping plate 17 to the upper end of the seedling platform 8
l ₁ is set so that it is not less than 1/2 of the total length l of the scoop plate 17 so that the center of gravity is located on the front side, and the lower end of the annular support member 19 is extended to support the seedling platform 8. By making contact with the scoop plate 17
The scoop plate 17 is received in a substantially horizontal position by the supporting member 19 whose swing is regulated and the upper end of the seedling stand 8. It is configured to be stopped and supported. With the above configuration, the scoop plate 17 can be maintained in a substantially horizontal position. Also, when the operator replenishes the spare seedlings 7 based on the display operation by the switch 23 upon sensing that the pine-shaped seedlings 7 are gone, the operator should use the hand side of the scooping plate 17 in this horizontal position. By lifting the seedling stand 7, it can be switched to an inclined position protruding from the upper end of the seedling stand 7.

[Another example]

As shown in FIGS. 4 to 6, the scoop plate 17
A guide plate 20 having a triangular shape in side view is provided in front of the angle part 16 on the lower surface of the angled part 16.
It may be configured so that the seedling box 21 does not get caught on the seedling box 21.

As shown in FIGS. 7 and 8, the angle portion 16 and the guide plate 20 may be integrally formed by stamping out of a single plate so that they can be stacked together to reduce the bulk.
