[Problem to be Solved by the Invention] During normal work in the above-mentioned seeding plant, almost all devices such as the first and second conveying devices and feeding devices are operated to supply soil for bed soil and covering soil. Soil is continuously pumped into each tank of the device. However, if a sufficient amount of soil is stored in each tank of the soil supply device for bed soil and covering soil,
When sowing in a small number of seedling boxes,
Seeding work may be carried out without operating the feeding device that supplies soil to the tank. Even when sowing is carried out under such conditions, the soil spilled during the supply of soil to the seedling box will be transported to the second storage section by the second transport device, so when the sowing operation is finished, the soil will be transferred to the second storage section. In some cases, a large amount of soil is returned to the inside of the unit, leaving the lower part of the feeding device as if it were buried in soil. Therefore, even if an attempt is made to operate the feeding device in order to resume normal seeding work in this state, the feeding device cannot operate if the lower part of the feeding device is filled with soil. If the feeding device is forced to operate, there is a risk that the feeding device will be damaged. An object of the present invention is to prevent the above-mentioned damage to the feeding device in a seeding plant.

[Means for Solving the Problems] The feature of the present invention is that the above-mentioned seeding plant is constructed as follows. In other words, [1] When the feeding device is not in operation,
A restraining means is provided to prevent the sowing operation of the seeding plant. [2] A control means is provided which automatically operates the feeding device in conjunction with the start of the seeding operation of the seeding plant.

[0005]

[Function] In the case of the configuration as described in the previous item [1], if the feeding device that replenishes soil to each tank of the soil supply device for bed soil and covering soil is not operated in advance, the seeding plant will not be able to sow. cannot be started. In the case of the configuration as in the previous item [2], when the seeding operation of the seeding plant is started, the feeding device that has been stopped automatically starts operating.

[0006]

Effects of the Invention As described above, by configuring the feeding device to always operate when the seeding operation of the seeding plant is started, the soil spilled when supplying soil to the nursery box can be Even when the soil is transported to the storage section, since the feeding device is in operation, there is no possibility that soil will accumulate in the second storage section, that is, the part of the feeding device. As a result, it is possible to prevent the feeding device from being buried in soil and unable to operate again, and to prevent damage to the feeding device.
