Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a soil supply structure for a tank that temporarily stores floor soil or soil for covering 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 into the nursery box from 6) in Fig. 4. 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 section is supplied from the transport device (19, 20 of FIG. 4 of the above publication) by the forward / reverse transport device (21 of FIG. 4 of the above publication) to the soil for floor soil and cover soil. It is released into each tank of the equipment through the opening on the top. The forward / reverse transporting device is configured to be appropriately switched between a normal rotation state in which it is discharged into the soil tank and a reverse rotation state in which it is discharged into the soil covering tank. 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 soil for floor soil or cover soil.

[0004]

[Problems to be solved by the device]

 As described above, when the granular soil is supplied from the forward / reverse transport device so that it is simply discharged into the tank, the soil as a granular material causes the soil to have one large pile in the tank. Become a state. 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.

[0005]

[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, in the forward / reverse transporting device, the soil discharging part on the floor soil tank side and the soil discharging part on the soil covering tank side reciprocate along the transport direction of the forward / reverse transporting device. A drive mechanism for reciprocating the transport device along the transport direction is provided.

[0006]

[Action]

 In the conventional structure, since the soil always drops from the forward / reverse transporting device to a fixed position in the tank, one large mountain is formed in the tank. On the other hand, when the forward / reverse rotation transport device is driven to reciprocate as in the present invention, for example, in the state where the forward / reverse transport device 14 is located on the leftmost side of the paper as shown in FIG. The soil from the discharge portion at the right or left end of the forward / reverse transport device 14 is guided and supplied to the left side of the paper in the tank 7 or 8. Then, from this state, when the forward / reverse rotation transport device 14 moves to the right side of the paper surface, the falling position of the soil moves to the right side of the paper face accordingly, and the forward / reverse rotation transport device 14 moves to the rightmost side of the paper face. When it moves, the soil from the forward / reverse transport device 14 is also guided and supplied to the right side of the paper in the tank 7 or 8. Then, such a state is repeated with the movement of the forward / reverse transporting device, and the position where the soil falls is repeatedly moved, so that the soil falls to a certain position and a mountain is formed in the tank. Such a situation does not occur.

Further, by reciprocally moving the forward / reverse conveyance device that distributes the soil to the tank for the soil and the tank for the soil, the pair of drive mechanisms for the forward / reverse conveyor can be used for the soil and the soil. It is possible to prevent piles from forming in both tanks.

[0008]

[Effect of the device]

 As described above, by moving the position where the soil from the forward / reverse transporting device falls in the tank, it was possible to prevent the formation of hills in the tank. As a result, it was possible to smoothly supply uniform soil from the tank into the seedling raising box, prevent poor seedling raising, and improve the working efficiency of the entire seedling plant. Further, by reciprocally moving the forward / reverse conveyance device by a set of drive mechanisms, the soil can be made uniform in both the soil tank and the soil covering tank, which is also advantageous in terms of manufacturing cost.
