[Industrial applications]

 The present invention relates to a soil supply structure to a tank for temporarily storing soil for floor soil or covering soil in a seeding plant in which soil and seeds are continuously placed in a nursery box for growing seedlings for planting crops. ..

[0002]

[Prior Art]

 An example of the above seed plant is disclosed in Japanese Patent Laid-Open No. 2-104206. In this seeding plant, first, a soil feeding device for floor soil (see the above-mentioned publication) is fed while continuously feeding a nursery box (1 from the above-mentioned publication in FIG. 4) by a conveyor (5 in the above-mentioned publication). Bed soil is supplied from 6) in Fig. 4 into the nursery box. Next, seeds are sown on the bed soil of the nursery box with a sowing device (8 in Fig. 4 of the above publication), and the soil is covered with a soil supply device for covering soil (9 of Fig. 4 of the above publication). It is a structure that covers the seeds. Then, the soil from the soil storage portion is discharged into the respective tanks of the soil supplying device for the floor soil and the soil covering from the opening on the upper surface thereof by the transport device (21 in FIG. 4 of the above publication). Is configured. In this case, since the floor soil or cover soil needs to have appropriate air permeability and water retention to retain water appropriately, fruit-like soil is used, and multiple types of soil with different particle sizes are used at a certain ratio. It is used as a soil for floor soil or cover soil.

[0003]

[Problems to be solved by the device]

 As described above, when the granular soil is supplied so that it is simply discharged into the tank from the transport device, the soil becomes one large mountain in the tank due to the nature of the soil as a granular material. Become. If such a mountain is formed in the tank, particularly large-diameter soil may roll down on the upper surface of the mountain and collect on the outer frame of the tank. In this case, the soil will not be uniform in the tank, and the floor soil or cover soil supplied into the nursery box will have a large amount of large diameter soil and a large amount of small diameter soil. An object of the present invention is to obtain a structure that can prevent the soil from becoming non-uniform in the above-mentioned tank for floor soil or cover soil as much as possible.

[0004]

[Means for Solving the Problems]

 A feature of the present invention is that the soil supply structure of the seed plant as described above is configured as follows. In other words, a guide member that divides the soil discharged from the transport device into soil flows in multiple directions and guides each of the soil flows to different positions in the tank is arranged below the transport device. ..

[0005]

[Action]

 In the conventional structure, since the soil is constantly discharged from the transport device to a certain position in the tank, one large mountain is formed in the tank. On the other hand, in the present invention, as shown in FIG. 1, for example, the soil discharged from the conveying device 14 hits the guide member 17 and is divided into soil flows in a plurality of directions. Each falls in a different position. Therefore, a plurality of small peaks corresponding to each soil flow will be formed in the tank 7. If the soil is divided into a plurality of small mountains as described above, even if large-diameter soil rolls down on these small mountains, the large-diameter soil will not concentrate only on the outer frame of the tank. It will be dispersed in the outer frame and the valley in the center of the tank.

[0006]

[Effect of the device]

 As described above, by dividing the mountain formed in the tank into a plurality of small mountains, it was possible to prevent the soil from concentrating on a part even if it rolled. As a result, it was possible to smoothly supply uniform soil from the tank into the nursery box, and to improve the efficiency of the whole sowing plant.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 shows the whole planting plant for rice, and an empty nursery box 2 is sent from the left side of the paper to the right side of the paper on the conveyor 1. Then, first, the soil is supplied from the soil supply device 3 for floor soil into the empty nursery box 2 and spread, and the floor soil is formed in the nursery box 2, and the excess floor soil is scratched by the rotary brush 4. I will be dropped. Next, seed paddy is sown from the seeding device 5 on the bed soil in the seedling raising box 2, and soil is supplied from the soil supply device 6 for covering soil to the seed pad in the seedling raising box 2 to form cover soil. go. In this way, the seedling-raising box 2 after sowing is further sent to the right side of the paper, stacked in multiple stages, and sent to the germination chamber (not shown).

The above-mentioned soil supplying devices 3 and 6 for floor soil and covering soil are respectively provided with tanks 7 and 8 for temporarily storing soil, and the soil supplying device 3 is provided from the bottom of the tanks 7 and 8. , 6 take out the soil one by one. Next, a structure for replenishing the tanks 7 and 8 with soil will be described.

As shown in FIG. 3, a first soil storage section 9 is provided for soil storage, and the soil of the first soil storage section 9 is transferred to a second soil by a first conveyor device 10 of a belt conveyor type. It is sent to the storage unit 11. In addition, when soil is supplied from the soil supply device 3 for floor soil, when scraped by the brush 4 and when soil is supplied from the soil supply device 6 for covering soil, soil spilled from the seedling raising box 2 is of a belt conveyor type. It is collected and transported by the second transport device 12 and is sent to the second soil storage section 11.

The soil in the second soil storage section 11 is scraped off and lifted by a bucket type feeding device 13. The feeding device 13 has a structure in which a large number of buckets 13b are bolted to an endless cloth belt 13a, and the soil lifted by the feeding device 13 is a belt conveyor type that is repeatedly driven forward and backward. The third transfer device 14 (corresponding to the transfer device to the tanks 7 and 8) distributes to the tanks 7 and 8, and the left and right ends of the third transfer device 14 open the openings 7a and 8a on the upper surfaces of the tanks 7 and 8. (See Fig. 1).

As shown in FIG. 1, contact type sensors 15a and 16a for detecting that the tanks 7 and 8 are filled with soil and that the soils in the tanks 7 and 8 have decreased to a predetermined amount. Contact-type sensors 15b and 16b for detecting and are provided, and when the tank 7 or 8 is full during the above-described normal work, the feeding device 13, the first, second and third transfer devices 10 and 12 are provided. , 14 are configured to stop automatically.
