Description

[Detailed description of the invention] [Industrial application field]

The present invention is a method for sowing seeds on a seeding sheet placed in a seedling nursery box, a field, etc.

[Conventional technology]

Conventionally, seeds, such as paddy, are adhered to a water-soluble rocking sheet with an adhesive such as glue, and this sheet is placed on the floor of a seedling box or in a water area. In addition, in IIs, a technique is known in which seedlings are raised and then grown directly.As a means of sowing seeds on this seeding sheet,
The surface of the sheet is coated with seed adhesive at predetermined intervals and wound into a roll, and as the roll is fed out horizontally, the #ff! Seeds are sown on a stalk sheet using a sliding #' device, and the seeds are adhered to a seed adhesive.

[Problems to be Solved by the Invention] By the way, in the above conventional technology, If! The device is
Since the seeds are simply swept in a constant amount onto the top of the seeding sheet, the excess seeds that are not attached by the seed adhesive must be removed from the seeding sheet. The seeding sheet is brought into contact with the surface of the seeding sheet in a sweeping motion to remove excess seeds, but this effect is not sufficient (i.e., the seeding sheet is manually cut into a predetermined size using a sewing machine, etc., and the excess seeds are removed). [Objective of the Invention] Therefore, the present invention improves the movement path of the sowing sheet after sowing, thereby making it possible to sow seeds without using the brush or the like. To provide a seeding device for a seeding sheet, which can reliably remove excess seeds on the sheet and collect the excess seeds without causing any negative effects on the seeds stuck by a seed adhesive by letting them fall naturally. This is what I am trying to do.

[Means for solving the problem] In order to achieve this object, the present invention involves rolling up a seeding sheet whose surface is coated with a seed adhesive at predetermined intervals, and moving this seeding sheet from one side to the other. During this time, seeds are sown on the surface of the sheet and adhered to the seed adhesive, and a bent part that bends in a figure 7 shape and descends is formed in the movement path of the sowing sheet, and in this bent part The present invention is characterized in that it is configured so that seeds that are not attached to the ladder adhesive fall from the seeding sheet and are collected. [Embodiments] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes the pedestal of the seeding device, and this pedestal 1 is formed with a lower pedestal 1a and an upper pedestal 1b whose surfaces are almost horizontal, with a step difference, and the seeding mechanism is on the lower pedestal 1a side. The seeded sheet is placed on the upper pedestal 1b and is moved. A pair of left and right support frames 2 are erected on the upper pedestal 1a, and a support shaft 3 that can be inserted into and removed from the upper starting end of the support frame 2 is inserted into the support frame 2.
A seeding sheet roll 4 is rotatably supported. This seeding sheet roll 4 has a ladder adhesive applied to its surface continuously at predetermined intervals along its length, and perforations are made at predetermined intervals perpendicular to the length direction. ,
Composed of slightly thick paper or synthetic resin film,
This sheet has the property of dissolving when placed on the bed soil of a seedling nursery box or in the field and watered, or when moisture is absorbed from the bed soil or cultivated soil. The support frame 2 on the front side of the seeding sheet roll 4 includes:
- A seed hopper 5 is provided, and a seed feeding section 5a is installed at the bottom of this hopper 5. Below the seed dispensing portion 5a, a dispensing roll 6 is pivotally supported by a rotating shaft 6a so that the sheet of the seeding roll 4 moves substantially horizontally. The outer periphery of both ends of this feed roll 6 is provided with protrusions that engage with the percolation installed at both ends of the seeding sheet roll 4. The support frame 2 below the feed roll 6 is bent rearward,
A pair of left and right feed rolls 7 are rotatably supported on a straight portion of the bent support frame 2 by a shaft 7a. These feeding rollers and lures may also be provided with protrusions that engage with the sheet perms, or may be flat rolls as shown in the drawings. Therefore, the feeding roller 6 and the feeding roller 1
The sowing sheet moves along a movement path that has a figure 7 shape when viewed from the side, and a seed tray 8 is supported slightly below the front side of the feed roll 6 by a support base 8a.
It is designed to receive seeds falling from the sowing seams 1 to 1. At a front position facing the feed rolls 7, a pair of upper and lower feed rolls 10.11 are pivotally supported by a pair of left and right support frames 9 via shafts 10a and 11a. The seeding sheet is sent out to the soil of the upper pedestal 1b by the feeding action. Said sending out I:1. Like the feeding roller 6, the feeding roller 11 has protrusions formed at both ends thereof to engage with the percolation of the sheet, and the feeding roller 10 has grooves 10b formed at predetermined intervals around its periphery. This interval almost matches the application interval of the seed adhesive applied to the seeding sheet-F, and is designed to straddle the seeds adhered to the seeding sheet-F. A motor 12 as a prime mover is disposed on the pedestal 1a in the support frame 2, and a engine transmission system 1'3 is provided between the output shaft of the motor 12 and the rotating shaft 68 of the feed roll 6. A chain transmission system 14 is also provided between the rotating shaft 6a and the rotating shaft of the feeding section 5a, so that the feeding section 5a is operated. Further, a chain transmission system 15 is also provided between the output shaft of the motor 12 and the shaft 11a of the delivery roll 11, so as to rotate the delivery roll 11. In the seeding device with such a configuration, W1i! The sheet roll 4 is rotatably supported by the support frame 2 via the support shaft 3, and the sheet is fed out while pulling the end of the sheet and rotating the roll. When the motor 12 is driven in this state through the chain transmission system 13.
4. The feed roll 6, the feed roll 7, the feed roll 11, and the miko feed unit 5a are rotated via the i5, and the sheet is stored in the seed hopper 5, and seeds (for example, paddy) are fed out in predetermined portions. The sown chineat that has been bonded with an adhesive is continuously fed out onto the upper pedestal 1b through the feeding rolls 6, 7, and 10.11. While the sown sheet reaches from the feed roll 6 to the feed roll 7, the seeds that are not stuck on the sheet by the seed adhesive pass through the Z-shaped path and fall naturally, and the weighing result is placed in the book 8. be accommodated. Moreover, when the sown sheet passes between the rolls 10 and 11, grooves 10b are formed in the upper roll 10 at the same intervals as the seed sticking intervals, so that the seeds S stuck to the adhesive are will not peel off. The seeding sheet sent out onto the upper rack is separated from the perforations and laid on the floor of the seedling box, or it is laid in a long state on the leveled ridges of the field and covered with soil as necessary. . Then, the seeding sheet dissolves due to watering or absorption of moisture from the bed soil or soil, seeds germinate, and seedlings are grown.

【Effect of the invention】

As explained above, according to the seeding sheet sowing device of the present invention, a bent part that bends in a figure 7 shape and descends is formed in the moving path of the seeding sheet coated with a seed adhesive at predetermined intervals. Seeds that are not stuck to the adhesive of Sheet-F can be collected easily and easily, and since the seeds fall naturally and are collected, there is no chance of damage to the seeds and no waste. Furthermore, there is no need to install special equipment to collect seeds, and highly efficient sowing work can be performed with a simple configuration.
