Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a seed plant.

[0002]

2. Description of the Related Art Conventionally, as a form of a sowing plant, a soil filling device for filling soil in a seedling raising pot enclosed in a tray to be conveyed and a soil in a seedling raising pot conveyed from the soil filling device are used. There is one equipped with a crushing / seeding device for squeezing and sowing, and a soil covering device for covering soil in a seedling raising pot conveyed from the squeezing / seeding device.

[0003]

However, in the above-mentioned seeding plant, the trays are conveyed continuously in the soil filling device and the soil covering device, but the trays are conveyed in the crushing / seeding device by a reliable crushing operation and a sowing operation. Since the intermittent transfer is performed to ensure the safety of the soil, when the operation switch of the sowing plant is turned on, if the previous tray remains in the soil filling device or the pressure suppressor / seeder, the tray in the intermittent pressure suppressor / seeder is transferred. However, there was a problem that the seeding work efficiency decreased as a result of congestion.

[0004]

Therefore, in the present invention, a soil filling device for filling soil into the seedling raising pot placed on the tray to be conveyed, and a seedling raising pot conveyed from the same soil filling device. A sowing plant comprising a squeezing and seeding device for squeezing the soil in the plant and sowing, and a soil covering device for covering the soil in the seedling raising pot conveyed from the squeezing and sowing device. A tray detection sensor is attached to each of the starting end portion and the end portion of the soil filling device, and when both sensors detect a tray, the drive unit of the soil filling device is stopped via the control unit. The seeding plant will be provided.

[0005]

[Function] When seeding in the seedling raising pot, when the operation switch of the seeding plant is turned on, the tray on which the seedling raising pot is placed is conveyed to the soil filling device, and the seedling pot is placed in the seedling raising pot. After the soil is filled, the tray with the soil filled in the seedling raising pot is transferred from the seedling filling device to the crushing / seeding device, where the soil filled in the seedling growing pod is crushed. At the same time, seeds were sown on the same soil, and subsequently the trays sown in the seedling raising pot were transported from the crushing and seeding device to the soil cover device,
With the soil covering device, soil is covered on the seeds sown in the seedling raising pot.

When the operation switch is turned on,
When the tray detection sensor attached to each of the starting end of the crushing and seeding device and the starting end of the soil filling device detects both trays, the drive unit of the soil filling device is stopped via the control unit. No tray loading or filling operation is performed.

Therefore, when the tray in the previous sowing work remains in the soil filling device or the crushing / seeding device,
Each of the drive units of the crushing / seeding device and the soil covering device is activated, and after the remaining trays are seeded and soiled, the trays are unloaded. Then, when the tray detection sensor attached to the starting end portion of the crushing / seeding device detects that there is no tray left, the drive unit of the soil filling device is operated via the control unit to carry out tray loading or filling operation. Be started.
