Raising Seeding Box Automatic Supply Apparatus

Abstract

An unsmooth conveying problem is caused when up and down stacked whole load is applied to a raising seeding box of the raising seeding box supply apparatus. In the raising seeding box automatic supply apparatus, the upper framework (11) is provided with a bearing supplying part (20) bearing a raising seeding box (A) group and supplying the same to the conveying device (1); behind and front of the left and right sides of a conveying direction of the raising seeding box (A) of the raising seeding box conveying device (1) on the upper framework (11) of the bearing supplying part (20) are respectively provided a pair of spiral bodies (21) containing spiral wings (23) and bearing the laminated raising seedinb box (A) and decescending the same; and an approximately horizontal plane part (24) bearing the stacked raising seeding box (A) is formed on the spiral wing (23) on the topmost end of the spiral body (21).

Description

technical field [0001] The invention relates to an automatic supply device for a seedling raising box. Background technique [0002] In the past, it is known that a seedling box supply device is provided at a position above the start end of a seedling box transfer device having a transfer unit that transfers the seedling box from the beginning end to the terminal end. The structure of a supply part (patent document 1). [0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 60-199404. [0004] In the above-mentioned known example, since the rear side of the seedling box is supported by coils, the weight of the stacked seedling box is applied to the front part of the seedling box being transferred by the transfer device, so there is a problem that problems such as hooking occur. .

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned known example, since the rear side of the seedling box is supported by coils, the weight of the stacked seedling box is applied to the front part of the seedling box being transferred by the transfer device, so there is a problem that problems such as hooking occur.

[0005] Moreover, in the known example, although the coils are used to lower the seedling box, the pitch of the coils must be matched with the vertical height of the seedling box, which requires a high degree of manufacturing accuracy and assembly accuracy, and there are problems of expensive manufacturing and assembly costs.

[0006] In addition, in the known example, there is a problem that it cannot be used in seedling boxes with different heights in order to match the pitch of the coils to the vertical height of the box.
