Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling raising apparatus for growing crop seedlings such as rice seedlings in a seedling raising box, and more specifically, it is necessary to load a sheet-shaped member into the seedling raising box. Regarding

[0002]

2. Description of the Related Art In a seedling raising device for seedling mat seedlings for machine planting, conventionally, as disclosed in Japanese Utility Model Laid-Open No. 3-105254, from the feeding of seedling raising boxes to the loading work of a trolley for germination processing, it is consistent. There was one that was configured so that it could be handled automatically by conveyor transportation. By the way, recently
Medium seedlings, which have a longer growth period than seedlings, are desired mainly in cold regions from the viewpoint of viability, and there is a growing demand for milk seedlings with a shorter growth period due to improved work efficiency by shortening the seedling growth period. ing. Therefore, when performing such seedlings using the above-mentioned seedling raising apparatus, for example, since seedlings are severely root-entangled in mid-sized seedlings, sowing cannot be performed in a densely seeded state like a young seedling, and a predetermined interval is set. It is necessary to sow the seeds in an empty space, and a method of sowing at a constant interval using a paper pot is adopted.
In addition, artificial seedbeds such as rock wool are used for dairy seedlings because the rooting is not sufficient. However, when a sheet-shaped member such as the paper pot sheet or artificial nursery bed is loaded into the nursery box, these sheet-shaped members are made of a relatively soft material such as paper or rock wool, and thus are difficult to adapt to automation, The loading operation of these sheet-like members has been performed manually by an operator.

[0003]

However, in the above-mentioned conventional structure, since the manual work of loading the sheet-like members is required during the automatic working process by conveying the nursery box on the conveyor, the working efficiency is lowered. There is an adverse effect that it is caused, and improvement has been desired. The present invention solves the above-mentioned problems, and even for seedlings that need to be loaded with a sheet-shaped member in the seedling raising box, a seedling raising apparatus that can handle seeding work, seeding work, irrigation work, etc. in a series of automated steps Is intended to provide.

[0004]

[Means for Solving the Problems] The features of the first aspect of the present invention include a nursery box feeding mechanism for continuously feeding a nursery box on a conveyor for feeding, and a bottom sheet for sequentially feeding each nursery box to be transported. A bottom sheet supply mechanism, a pot sheet supply mechanism for supplying a pot sheet in which seed holes have been formed at a predetermined pitch in the vertical and horizontal directions into each seedling raising box to be conveyed, above the pot sheet with respect to the conveyed seedling raising box A bed soil supply mechanism for supplying bed soil from the above, a seeding guide plate mounting portion for sequentially mounting seeding guide plates for sowing only to each of the seeding holes in the transported seedling growing box, and a vibration mechanism for vibrating the seedling growing box A seeding mechanism for sequentially sowing from the seeding guide plate in the seedling raising box to be transported, a seeding guide plate removing section for sequentially removing the seeding guide plate after being seeded, above the seed paddy supplied in the seedling raising seed box to be transported. Cover the soil Next supplying soil cover supply mechanism lies in that is provided with a respective watering mechanism for irrigating after being covered with soil.

The second aspect of the present invention is characterized in that a nursery box feeding mechanism for continuously feeding a nursery box on a conveyor for feeding, a nursery sheet feeding mechanism for sequentially feeding an artificial nursery sheet into each transported nursery box, Irrigation mechanism for irrigating the nursery sheet in each transported nursery box, seeding mechanism for sequentially seeding the nursery sheet to be transported on the nursery sheet, covering soil for supplying soil over the seeded paddy The point is that each of the supply mechanisms is provided.

[0006]

According to the characteristic construction of the first aspect of the invention, the seedling raising box feeding mechanism automatically feeds the seedling raising boxes continuously onto the conveyor, and the bottom sheet sheet feeding mechanism feeds the bottom sheet to the fed seedling raising boxes. Will be supplied in sequence. Then, the pot sheets are automatically loaded in sequence to the seedling raising box to which the bottom sheet has been supplied, and further, the bed soil is automatically fed into the seedling raising box from above, and the pot sheet is vertically and horizontally predetermined. Floor soil is supplied to the inside of the pot sheet through the seeding holes formed at intervals. After the bed soil is supplied in this way, seeds are surely supplied only from each sowing hole, and a sowing guide plate for preventing seeds from accidentally falling to other parts on the pot sheet is attached, and vibration is applied. The seedling box is forcibly vibrated by the mechanism so that the bed soil supplied only from the seeding holes can surely enter the bottom of the pot sheet, and a recess for allowing seeds to easily enter the surface of the bed soil facing outward from the seeding holes. Is formed. Then, after a predetermined number of seeds are seeded in the recesses for each seeding hole by the seeding mechanism, the seeding guide plate is removed, and soil is supplied to the upper part of the seed paddy, and then watering work is performed. Then, the predetermined process is completed. In this way, while the nursery box is being transported by the transport conveyor, each of the above working steps for growing mat seedlings by the intermediate seedlings is continuously and automatically performed, and then the subsequent steps such as the germination treatment step are performed. .

According to the characteristic construction of the second aspect of the invention, the seedling raising box feeding mechanism automatically feeds the seedling raising boxes continuously onto the conveyor, and the seedbed sheet feeding mechanism conveys the rockwool to the seedling raising boxes conveyed by the conveyor. After the artificial seedbed sheet made of wood or the like is automatically loaded, the artificial seedbed sheet is watered, and then seeding work is performed in a densely seeded state on the seedbed. Then, the upper part of the seed paddy is covered with the soil cover supplied by the soil cover supply mechanism, and the predetermined working process is completed. In this way, each of the above-mentioned work steps for growing mat seedlings with milk seedlings is continuously and automatically performed while the seedling raising box is being transported by the transport conveyor, and then the subsequent steps such as the germination treatment step are carried out.

[0008]

[Effects of the Invention] Therefore, even for seedlings that require a sheet-like member made of a relatively soft material such as a pot sheet or an artificial seedbed sheet to be loaded into the seedling raising box, a series of work steps such as seeding work requires a seedling raising box. Thus, a seedling raising apparatus capable of automatically transferring the seedlings is provided, and a troublesome operation such as a manual loading operation of a sheet-shaped member is not required, and work efficiency is improved.
