[Detailed description of the device]

[0001]

[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 by the transporting device (21 in FIG. 4 of the above-mentioned publication) from the opening on the upper surface thereof. 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, granular 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 from the transport device so that it is simply discharged into the tank, the soil becomes a 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. With this, the soil is not uniform in the tank, and the floor soil or cover soil supplied into the nursery box has a large amount of large-diameter soil or a large amount of small-diameter soil. An object of the present invention is to obtain a structure capable of preventing 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. That is, a guide member is provided that is repeatedly switched between a posture in which the soil discharged from the exit of the transport device is guided in the same direction as the transport direction of the transport device and a posture in which the soil is guided in the opposite direction.

[0005]

[Action]

 In the conventional structure, the soil is constantly falling from the transfer device to a certain position in the tank, so one large mountain is formed in the tank. On the other hand, if the guide member 17 driven as in the present invention is provided, for example, as shown by the solid line in FIG. 2, the lower part of the guide member 17 is located on the leftmost side of the drawing (in the same direction as the carrying direction of the carrying device 14). (Corresponding to), the soil from the transport device 14 is guided and supplied to the left side of the tank 7 in the drawing. Then, when the guide member 17 moves to the right side of the paper from this state, the position where the soil drops from the transport device 14 also moves to the right side of the paper along with this, as shown by the chain double-dashed line in FIG. Thus, when the lower part of the guide member 17 moves to the rightmost side of the drawing (corresponding to the direction opposite to the conveying direction of the conveying device 14), the soil from the conveying device 14 is also guided and supplied to the right side of the drawing of the tank 7. Such a state is repeated with the movement of the guide member 17, and the position where the soil falls repeatedly moves. Therefore, the state where the soil falls to a certain position and a mountain is formed in the tank Does not happen. Every time the guide member faces in the direction opposite to the conveying direction, the soil is agitated at the portion of the guide member, so even if the soil is divided into large-diameter soil and small-diameter soil on the conveying device. , And is mixed again by the guide member.

[0006]

[Effect of the device]

 As described above, by moving the position where the soil from the transport device falls in the tank by the guide member, it was possible to prevent the formation of hills in the tank. As a result, it became possible to smoothly supply uniform soil from the tank into the seedling raising box, prevent poor seedling raising, and improve the efficiency of the whole seeding plant.
