Description

[Detailed Description of the Invention] In flooded rice fields, there is a layer of water or sludge on the topsoil. For example, even when seed rice coated with an oxygen supplying agent is directly sown, the seed rice floats in the water or sludge, or There were problems such as inaccurate sowing due to being washed away, and uneven planting depth due to uneven topsoil.

This invention provides a trench cutting device for flooded rice fields for seeding, fertilization, etc., which can eliminate water and sludge in flooded rice fields and extremely easily form smooth topsoil suitable for granule dispersion. .

That is, the present invention provides a boat-shaped box having a sled for cutting grooves on the front part, and a drainage groove opening at the rear end face of the box is provided on the bottom surface of the box. A reservoir for seeding, fertilization, etc., characterized by having a granule input port located above the drainage channel and a rotatable drainage wheel behind the input port. The gist of this paper is the structure of a ditch cutting device for paddy fields.

The present invention will be described with reference to the illustrated embodiment. Reference numeral 1 denotes a box body, and a sled 2 for cutting grooves is formed in the front part in a bulging boat shape. A long drainage groove 3 is formed in the bottom surface of the box 1 in the front and back, and the rear end thereof is an opening 4 in the rear end surface of the box 1. On the upper surface of the box 1, a hole 5 for introducing the granules a is opened, located above the drainage groove 3. A conduit 7 of a granule feeding device 6 is removably fitted into the inlet 5, and is provided so that the granules a can be dispersed into the drain groove 3.

Reference numeral 8 denotes a drainage wheel, which has a plurality of blades 9, 9, . That is, the drainage wheel 8 is provided so as to be rotatable by engaging the tips of blades 9 with the topsoil A at the bottom of the drainage ditch 3 as the box 1 moves.

Note that FIGS. 3 and 4 show other embodiments of the present invention, in which FIG. 3 is a longitudinal sectional side view and FIG. 4 is a bottom view thereof. According to this embodiment, two drain grooves 3, 3 are provided in parallel, passing through the bottom surface of the rear part of the box 1, and opening 4 at the rear end face.

Since this invention is configured as described above,
When this is placed on the top surface of a flooded field, water and sludge B enter the drainage groove 3 on the bottom surface of the box 1, and the sled 2 presses the top surface of the topsoil A and comes to rest. Therefore, when this box 1 is run by an appropriate means, the upper surface of the topsoil A is smoothly grooved by the sled 2, and the water and sludge B in the drainage ditch 3 are removed to the rear of the box 1 by the drainage wheel 8. It turns out.

To explain this drainage vehicle 8 with reference to FIGS. 5 to 7, the blades 9 facing downward thrust their tips into the topsoil A, and as shown in FIG. B is isolated. Next, when the drainage wheel 8 rotates approximately 30 degrees as the box 1 moves, it becomes as shown in Fig. 6, and the water and sludge B in the drainage groove 3 are disposed between the two downward facing blades 9, 9. is retained. When it is further rotated by 30 degrees, it becomes as shown in Fig. 7, and the water and sludge B held by the two blades 9, 9 flows from the rear end opening 4 of the case 1 to the rear of the case 1. will be excluded. The drainage truck 8 repeats the above drainage work as the box 1 travels, and drains the drainage ditch 3.
Since the water and sludge B inside are pumped out efficiently, the upper surface of the topsoil A, which has been smoothly cut by the sled 2, is finally exposed on the bottom surface of the drainage ditch 3.

Therefore, in this invention, the granule feeding device 6 installed on the top surface of the box 1 is connected to the box 1 by some means.
If it is linked to the running of the box 1, for example, the coated rice seed A can be sown directly onto the top surface of the topsoil A from which water and sludge B have been removed, thereby significantly improving the sowing accuracy. I can do it.

As described above, according to the present invention, water and sludge inside the box are removed as the box runs, and the top surface of the topsoil, which is suitable for seeding or granular dispersion, is extremely easily exposed in the drainage ditch on the bottom of the box. It has.
