る。An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 is a seed hopper for accommodating naked seeds A, and a discharge port 1a for discharging seeds in a fixed amount is provided in the lower part of the hopper 1. A first seed rectification gutter 2 is provided below the discharge port 1a. This first seed straightening gutter 2 has a predetermined length and has a V-shaped cross section, so that the seed discharge end 2b side descends from the seed supply end 2a side toward the seed discharge end 2b side. It is inclined, and the vibrating device 3 is attached to the lower surface. Below the discharge end 2b of the first seed flow straightening trough 2, a second seed flow straightening trough 4 having a predetermined step is provided. This second seed straightening gutter 4 is also inclined so as to descend from the seed supply end 4a side toward the seed discharge end 4b side, and is provided with a vibrating device 5. The tilt angles of the first and second seed straightening gutters 2 and 4 are adjustable, and in this embodiment, the tilt angle of the first seed straightening gutter 2 is the tilt angle of the second seed straightening gutter 2. It is slightly smaller. Further, the vibration intensity of the vibrating devices 3 and 5 can be adjusted. Seed sensors 6 and 7 are provided facing the various child discharge ends 2b and 4b of both seed rectification gutters 2 and 4, respectively. The both sensors 6 and 7 are optical sensors, and detect the seeds falling from the seed discharge ends 2b and 4b, and the seed feeding amount from the hopper 1, the inclination angle of the seed rectifying troughs 2 and 4, the vibrating device 3, It is to adjust the amplitude, strength, etc. of 5. A seed conveyor 8 is provided toward the seed discharge end 4b of the second seed straightening gutter 4. A seed box 9 is provided below the discharge end of the seed conveyor 8 so that the seed discharged from the seed conveyor 8 can be sown while moving. In the seed supply device having such a configuration, the seeds A stored in the seed hopper 1 are discharged from the discharge port 1a by a predetermined amount and are supplied to the seed supply end 2a of the first seed straightening trough 2. In the seed rectifying trough 2, the inclination is gentle, and the vibration is applied by the vibrating device 3, and the seeds flow toward the seed discharging end 2b, and in the flowing process, they are separated into individual grains and fall from the seed discharging end 2b. Then, it is supplied to the seed supply end 4a side of the second seed straightening gutter 4. The seeds falling from the seed discharge end 2b to the seed supply end 4a are detected by the seed sensor 6, and the seed discharge amount from the seed discharge port 1a and the seed rectification gutter 2 are detected according to the amount of the drop.
The tilt angle, the amplitude and strength of the vibration device 3 are adjusted. The seeds discharged from the first seed straightening unit 2 are separated into single grains and are kept at a predetermined interval. However, in the second seed straightening trough 4, the seeds act to further stabilize the seed intervals. To do. That is, the second seed straightening gutter 4 has a larger inclination than the first seed straightening gutter 2, and the interval between seeds is further widened. The tilt angle of the seed rectifying gutter 4 and the amplitude and strength of the vibrating device 5 are adjusted so that The seeds discharged from the second seed straightening gutter 4 are placed one by one at a predetermined interval on the seed conveyor 8 and moved, and are sown on the soil in the sowing box 9, but fall from the seed straightening gutter 4. The intervals between the supplied seeds and the moving speed of the seed conveyor 8 may be synchronized. The movement speed of the seed conveyor 8 can also be adjusted by detecting the seeds by the sensor 7. In the above embodiment, the second seed straightening gutter 4 is omitted, and depending on the type of seed, the first seed straightening gutter 2 alone can sufficiently achieve single seeding and uniform seed intervals. .

能率に実施することができる。As described above, according to the seed feeding device of the present invention, the seed straightening gutter having a predetermined length is tilted from one end to the other end so that the tilt angle can be adjusted, and the vibration is applied to the seed straightening gutter. A mechanism is provided, and a plurality of such seed rectification gutters are arranged so that the other end and one end of each of them are communicated with each other, and a sensor is provided at the seed discharge part of the other end, and seeds are provided on one end side of the seed rectification gutter. In the process of flowing the seed supplied through the hopper toward the other end side, the seed is made into single grains, and discharged at substantially equal intervals, and the discharged seed is detected by a sensor, and the seed discharge amount from the seed hopper, Since the tilt angle of the seed rectification gutter, the amplitude and strength of the vibrating mechanism, etc. are adjusted, the seeds supplied can be reliably made into single grains and discharged (supplied) while keeping the seed interval almost constant. Highly efficient seeding work can be performed. Further, since the seeds are rectified by vibration, it is easy to make single grains into any seeds by adjusting the inclination angle of the rectifying trough, the vibration strength, etc., and the seed interval can be made constant. Further, since accurate seed singulation and constant seed interval can be performed as a flow work, seed supply and seeding work can be performed with high efficiency.
