Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an extension frame for a seeding device.

(Prior Art) Japanese Utility Model Application No. 60-116810, which is well known in the art, describes a device in which an extension frame, an auxiliary frame, and a seedling box transfer belt are provided at the terminal end of a transfer table.

Furthermore, the conventionally known Japanese Utility Model Application Publication No. 59-110521 describes a device in which an extension frame with freely rotating rolls is provided.

(Problem to be solved by the invention) The former has a structure in which a long seedling box transfer belt is provided spanning the extension frame and the auxiliary frame, so it cannot be made inexpensively.

The latter only has an extension frame with free rotation rolls, so the seedling box cannot be transported over long distances.

(Purpose of the invention) The present invention is a device in which an auxiliary frame is provided after an extension frame so that a seedling growing box can be transported to a long distance, and can be formed at a low cost.

(Means for Solving the Problems) Therefore, the present invention provides a bed soil supplying device 3 on the top of a transfer table 1 for transferring seedling boxes 4, in which the end surface 20 of the terminal end 5 of the transfer table 1 is The end faces of the starting end of the extension frame 6 are butted against each other, and the upper position of the abutting part is fixed by a shaft 19. A free rotating pulley 9 is provided at the terminal end 8 of the extension frame 6. A drive pulley 7 is fixed to the drive pulley 7, a seedling box transfer belt 10 is routed between the drive pulley 7 and the free rotation pulley 9, and the extension frame 6 is attached to the end of the end 8 of the extension frame 6. The removable seedling box transfer belt 10 that can be further extended is provided with an auxiliary frame 17 that is not hung around, and a starting end of a rod-shaped auxiliary rail 16 is provided at the terminal end 8 of the extension frame 6 a little inside the free rotation pulley 9. 22 is fixed by the shaft 15, and the auxiliary rail 16 has its longitudinal intermediate position supported by the upper surface of the free rotation pulley 9, and extends from the use position located between the auxiliary frame 17 to the shaft 15. This is an extension frame for the seeding device that can freely rotate between the storage position when folded inward around the center.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 is a transfer table for transferring a seedling raising box 4, a bed soil supply device 3 is provided on the upper part of the transfer table 1, and an end portion 5 of the transfer table 1 is provided.
A pressure roll 13 and a leveling brush 14 are provided on the upper part of the machine. The pressure roll 13 has a protrusion 1 on the top of the terminal end 5.
1 is provided protrudingly, and a rotating arm 1 is provided on the upper part of the protruding piece 11.
2 is pivoted, and a pressure roll 13 is pivoted to the rotating end of the rotating arm 12. The pressing roll 13 comes into elastic contact with the upper surface of the seedling growing box 4 being transferred, and presses the bed soil. The leveling brush 14 is attached to the upper end of a rotating case 18 that is pivoted to the transfer table 1, and comes into contact with the upper surface of the seedling growing box 4 that is being transferred to level the bed soil.

As shown in FIG. 2, the vertical end surface 20 of the terminal end 5 of the transfer table 1 is brought into contact with the vertical end surface 21 of the starting end of the extension frame 6, and the upper position of the abutting part is aligned with the shaft 19.
The extension frame 6 is pivoted to allow the transfer table 1 to rotate freely between a use position in which it is extended horizontally and a storage position in which it is folded upward.

An auxiliary frame 17 for horizontally extending the extension frame 6 is detachably provided at the terminal end 8 of the extension frame 6.

A driving pulley 7 is provided at the terminal end 5 of the transfer table 1.
A free rotation pulley 9 is fixed to the terminal end 8 of the extension frame 6, and a seedling box transfer belt 10 is passed between the drive pulley 7 and the free rotation pulley 9.

A starting end 22 of a rod-shaped auxiliary rail 16 is fixed by a shaft 15 at a position of the terminal end 8 of the extension frame 6 slightly inside the free rotation pulley 9. The auxiliary rail 16 is rotatable between a use position where the seedling box transfer belt 10 is horizontally extended and a storage position where the auxiliary rail 16 is folded in a > shape with respect to the extension frame 6. When rotated to the horizontal use position, the intermediate position in the longitudinal direction is supported by the upper surface of the free rotation pulley 9 (FIG. 1).

(effect) Next, we will discuss the effect.

When the extension frame 6 is rotated horizontally about the shaft 19, the edge 21 at the starting end of the extension frame 6 abuts against the end surface 20 of the transfer table 1 and is fixed horizontally. Next, when the auxiliary rail 16 is rotated around the shaft 15, the intermediate position in the length direction of the auxiliary rail 16 is supported on the upper surface of the free rotation pulley 9, and is supported horizontally as shown in FIG. Ru.

When the seedling raising box 4 is transferred in this state, when the seedling raising box 4 passes under the bed soil supply device 3, the bed soil is supplied, the excess bed soil is removed by the leveling brush 14, and the pressing roll It was suppressed at 13 and moved on.

Then, it transfers onto the seedling box transfer belt 10,
The seedling raising box 4 is transported for an extended period. When the worker grasps the front end of the seedling growing box 4 that is on the seedling growing box transfer belt 10 and pulls it smoothly forward, the seedling growing box 4 can be pulled out onto the auxiliary rail 16 between the auxiliary frames 17. Hold the front and back to grate and remove.

When the work is finished, remove the auxiliary frame 17, rotate the auxiliary rail 16 to store it, and move the extension frame 6 upwards.
3 can be lifted up and folded into two tiers as shown in Figure 2.

(Effects) In the present invention, a bed soil supply device 3 is provided on the upper part of the transfer table 1 for transferring the seedling raising box 4, and the end surface of the starting end of the extension frame 6 is attached to the end surface 20 of the terminal end 5 of the transfer table 1. The upper position of the abutting part is fixed by a shaft 19, and a free rotation pulley 9 is provided at the terminal end 8 of the extension frame 6, and the transfer table 1
A driving pulley 7 is fixed to the terminal end 5 of the extension frame 6, a seedling box transfer belt 10 is routed between the driving pulley 7 and the free rotation pulley 9, and the front end 8 of the extension frame 6 has the The removable seedling box transfer belt 10 for further extending the extension frame 6 is provided with an auxiliary frame 17 that is not hung around, and a rod-shaped auxiliary frame is provided at the terminal end 8 of the extension frame 6 a little inside the free rotation pulley 9. rail 16
The starting end 22 of the auxiliary frame 17 is fixed by a shaft 15, and the auxiliary rail 16 is supported at its intermediate position in the longitudinal direction on the upper surface of the free rotating pulley 9.
Since the extension frame of the seeding device is designed to be rotatable from the usage position located between the two positions to the storage position folded inward around the shaft 15,
When compared with Publication No. 116810, the length of the seedling box transfer belt 10 is halved, making it cheaper and less expensive.
When compared with Publication No. 59-110521, the publication does not have anything that corresponds to the auxiliary frame 17 and auxiliary rail 16 of the present application, so the seedling raising box cannot be transported far, but the present application does not have anything corresponding to the auxiliary frame 17 and auxiliary rail 16. Therefore, it is possible to transport the seedling raising box 4 over a long distance with an inexpensive configuration.
