Abstract

PROBLEM TO BE SOLVED: To provide a seeder capable of solving such a problem of the conventional seeder that a seeding device casts seed on a seedling tray successively coming up via a conveyor, a sensor senses the state of the cast seed on the tray so as to control an amount of seed to be cast on the following seeding tray according to overs and shorts of the cast seed on the sensed tray and resultingly the sensed tray is forced to be thrown out because of a failure to adjust the sensed amount of the cast seed. SOLUTION: This seeder comprises: the first seeding device 6 and second seeding device 7 disposed in this order on a conveyor 2 carrying a seedling tray 1; and a sensor 9 placed before the second seeding device 7 for measuring an amount of seed cast in the seedling tray 1 by the first seeding device 6, wherein the second seeding device 7 seeds in the seedling tray 1 according to the detected value when the detected mount of seed is deficient.

On the conveyor 2, a soil filling device 4, a watering device 5, a first seeding device 6, a second seeding device 7, and a soil covering device 8
Are arranged from right to left in this order, and switches S1, S2, S3, S4, and S5 are provided on the right (front) of each. When the seedling box 1 sent by the conveyor 2 arrives at the switch S1, the soil filling device 4 is activated to pack the floor soil into the seedling box 1 when passing under it. When the seedling box 1 filled with the floor soil comes to the switch S2, the watering device 5 is operated to spray water (watering) on the floor soil in the seedling box 1 passing thereunder.
I do. When the seedling box 1 comes to the switch S3, the first sowing device 6 is operated to sow (seeding) seeds on the floor soil of the seedling box 1 passing thereunder. A photosensor (sensor) 9 is provided on the conveyor 2 between the first sowing device 6 and the second sowing device 7, and when the seedling box 1 is sent by the conveyor 2, the seeding state on the floor soil ( The seeding amount is detected, and the detected value is input to the control device 10.
When the control device 10 is incorporated in the control panel 11 and the above detection value is too low (the seeding amount is too small), the seedling box 1
Comes to the switch S4, the second sowing device 7 is operated, and when the seedling box 1 passes below the seeding box 1, seeds are sown on the bed soil. In addition, seeds are not limited to seed rice for paddy rice, and vegetable seeds can be used. When the detection value of the photo sensor 9 has reached the reference, the control device 10
Is not output to the second seeding device 7. Therefore, at this time, even if the seedling box 1 arrives at the switch S4, the second seeding device 7 does not operate, and the seedling box 1 passes below it. Therefore, it is preferable that the first seeding device 6 be configured so as to seed a slightly smaller number of seeds.

When the seedling box 1 sowed on the floor soil is sent by the conveyor 2 and reaches the switch S5, the soil covering device 8 starts operating so that the seeds of the seedling box 1 passing below are covered with the seeds. Has become. FIG. 3 shows another seeder. That is, the seeding device 12 is configured as a single unit, and the subsequent photosensor 13 detects the amount of seeds on the floor in the seedling box 1 where the seeding device 12 is seeded and inputs the detected amount to the control device 14. The V-belt 2c of the conveyor 2 is configured to be driven by the speed change motor 15, and this is operated by the output of the control device 14 as follows. If the detection value of the photo sensor 13 is small (the seeding amount on the floor soil is small), the transmission motor 1
5, the rotation speed of the V-belt 2c decreases, the feed speed of the seedling box 1 decreases, and the seeding density (the amount of seeding per box) increases. Conversely, if the detection value of the photo sensor 13 is large, the speed change motor 15 increases in speed, the feed speed of the seedling box 1 increases, and the seeding density decreases. Thus, the photo sensor 13
The feeding speed of the seedling box 1 is increased or decreased according to the detection result, and the seeds are scattered to the set density on the floor soil of the seedling box 1 that is subsequently sent.
