Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a sowing apparatus.

(Prior Art) Conventionally known, Japanese Utility Model Application Laid-Open No. 63-119308 discloses a seed comprising a seed supply hopper and a horizontal axis feeding roll having a feeding recess on the outer peripheral surface thereof, on the upper part of a horizontal feeding table of a seedling raising box. A seeding device for a nursery box provided with a supply device is described.

(Problems to be Solved by the Invention) In the case of the above-mentioned known seeds, in the case of wet sprouting seeds, the seeds adhere to the feeding recesses of the horizontal axis feeding roll due to moisture on the seed surface, and the seeds cannot be sowed smoothly. There are also people who supply sprouted seeds to the hopper without draining.

(Purpose of the Invention) As described above, the present invention allows seeds to be sown even if sprouted seeds are supplied to a hopper without draining.

(Means for Solving the Problem) Therefore, the present invention provides a seeding apparatus including a seed supply hopper 3 and a horizontal axis feeding roll 15 provided at a position below the seed supply hopper 3. The seeding device is configured so that the wet seeds 7 are dried and sown with the suction port 8 of the suction fan 25 facing the horizontal axis feeding roll 15.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a seed supply device provided at a position above a horizontal transfer table 2 for laterally feeding a seedling raising box. A seed supply hopper 3 is provided. In the lower part of the seed supply hopper 3,
The front side flow board 4 and the rear side flow board 5 are provided in an octagonal shape.

On the lower edge of the front side flow board 4, a flow down board 6 in the left-right direction is provided over the entire width. In the falling plate 6, suction ports 8 long in the flowing direction of the seeds 7 are formed at predetermined intervals in the left-right direction (FIG. 2). The suction port 8 is formed narrower than the lateral width of the seed 7 so that the seed 7 does not drop.

Below the falling plate 6, a suction chamber 9 for sucking air from the suction port 8 of the falling plate 6 and drying the seed 7 passing over the falling plate 6 is formed.

A suction pipe 10 connected to a suction fan 25 provided outside the apparatus is connected to the suction chamber 9. In addition, a cleaner 26 is provided in a suction air passage between the suction chamber 9 and the suction fan 25.

Reference numeral 11 denotes an outlet of the seed supply hopper 3 formed between a lower end of the rear flow plate 5 and an upper surface of the flow plate 6, and 12 denotes the rear flow grain for adjusting the size of the outlet 11. This is a supply amount adjusting plate of the supply amount adjusting device 13 provided on the plate 5.

A left-right brush 14 is provided at the lower end edge of the falling plate 6, and the tip of the brush 14 is slidably contacted with the outer peripheral surface of a left-right horizontal shaft feeding roll 15 for feeding the seed 7.

On the outer peripheral surface of the horizontal shaft feed roll 15, a horizontal groove-shaped feed concave portion 16 parallel to the generatrix direction is formed on the entire circumference at a desired interval. The feeding concave portion 16 is formed to have a width in which the seeds 7 are fitted in a horizontal row.

Slits 17 are provided on the outer peripheral surface of the horizontal axle feeding roll 15 on the entire circumference at intervals shorter than the horizontal width of one seed 7 in the left-right direction. The depth of the slit 17 is the same as or slightly deeper than the feeding recess 16, and a scraping knife 18 is fitted into each slit 17.

A second rotation leveling brush 19 is provided at a position substantially above the horizontal axis feeding roll 15, and is formed by the second rotation leveling brush 19, the outer peripheral surface of the horizontal axis feeding roll 15, and the upper surface of the flow-down plate 6. A first rotating leveling brush 21 is provided between the seed supplying unit 20 formed in the space to be formed, and the excessive seeds rotating together with the horizontal axis feeding roll 15 by the two rotating leveling brushes 19 and 21 are used as the seeds. It is swept back to the supply unit 20 in two stages.

Reference numeral 22 denotes a seed guiding cover provided on the side surface of the horizontal shaft feeding roll 15, and guides the seeds fitted in the feeding recess 16 from the upper position to the lower position so as not to be damaged. 23 is a seed induction cover
A sponge 24 provided inside the 22 is a seed receiving box, which has an effect of removing the winged seeds 7 attached to the second rotating brush 19 particularly when sowing seeds.

3, 4 and 5 show embodiments of the suction port 8, in which the seed 7 always passes above the suction port 8.

(Operation) Next, the operation will be described.

The present invention is configured as described above. When the seeds 7 are put into the seed supply hopper 3 and the seedling box supplied with the floor soil is transferred by the transfer table 2, the seeds in the seed supply hopper 3 After flowing down, passing through the outlet 11 and reaching the falling plate 6, flowing down the falling plate 6 to the seed supply unit 20, and the seed supply unit 20 forms the feed recess 16 of the horizontal shaft feed roll 15. The horizontal roll 15 is rotated by the rotation of the horizontal roll 15, and the horizontal roll 15
Most of the excess seeds rotating with the first rotating leveling brush 21
By the second rotating leveling brush 19
The seeds 7 in the horizontal row are fitted in the seeds 16 and the seeds 7 fitted in the feeding recesses 16 are guided downward by the seed guiding cover 22, fall down at the lowest point, and are sown in the seedling raising box.

In this case, the spouted seeds 7 are not drained, and the hopper 3
In some cases, the seeds 7 adhere to each other due to moisture on the surface of the seeds 7 to form a lump, and do not fit well into the feeding recess 16.

In the present invention, the suction port 8 is formed in the falling plate 6 and the falling plate 6 is formed.
, The suction chamber 9 connected to the suction fan 25 provided outside the machine is formed, so that the seeds 7 flowing down on the downflow plate 6 are formed.
Is dried by suction air sucked from the suction port 8,
It fits smoothly into the feeding recess 16 of the horizontal shaft feeding roll 15.

Further, the suction port 8 is formed in the falling plate 6, and the seed supply unit 20 is provided.
Is formed by the outer peripheral surface of the horizontal axis feeding roll 15 and the upper surface of the falling plate 6, so that the seeds 7 in the seed supply unit 20 are constantly blown by suction air and dried. Therefore, among the seeds 7 put into the seed supply hopper 3, the first seed 7 reaches the seed supply unit 20 through the outlet 11 from the seed supply hopper 3.
It can be dried before it fits into the feeding recess 16 at 20,
It fits smoothly into the feeding recess 16.

(Effect) Conventionally known, Japanese Unexamined Utility Model Publication No. 63-119308 discloses a seed supply comprising a seed supply hopper and a horizontal axis supply roll having a supply recess on the outer peripheral surface thereof, above a horizontal transfer table of a seedling raising box. A seeding box seeding device provided with the device is described.

When the known seeds are supplied to the hopper without draining the seeds, the seeds adhere to the feeding recesses of the horizontal axis feeding roll due to moisture on the surface of the seeds, and the seeds cannot be seeded smoothly.

However, the present invention relates to a seed supply hopper 3 and a horizontal axis feeding roll 15 provided below the seed supply hopper 3.
The seed supply hopper 3
And the horizontal axis feeding roll 15 is a sowing apparatus in which the suction port 8 of the suction fan 25 is exposed to dry and sow the wet seed 7. Even if the wet seeds 7 are put into the hopper 3 without being sucked, the wet seeds 7 can be dried before being fitted into the feeding recess 16 by the suction air sucked from the suction port 8, and can be smoothly inserted into the feeding recess 16 of the horizontal shaft feeding roll 15. And an effect that an accurate seeding amount can be accurately seeded.
