DETAILED DESCRIPTION OF THE INVENTION
【Example】
Hereinafter, the irrigation membrane generating apparatus according to the present invention will be described in detail with reference to an embodiment diagram. As shown in FIG. The stretched floor soil frame (6) and the sowing frame (7) are connected and connected to form a straight conveyance path (1) on the conveyance belt (5), and on the conveyance belt (5). Watering is carried out on the soil that has been put into the sowing box (2) that has been placed and transported in the transport direction (a) in the transport path (1), the soil leveling that has been put in, and the soil that has remained in the sumi. However, after irrigation, sowing and covering treatments are performed.
[0006]
As shown in FIGS. 1 and 2, the irrigation generating device for irrigating among the above processes is a case-like shape fixed on both sides of the floor soil frame (6) and positioned above the transfer passage (1). Two irrigation pipes (3) and (3) are installed in the machine body so as to be substantially perpendicular to the conveying direction (a) with a space in the front and rear direction, and on the lower surface of each irrigation pipe (3) and (3). Is provided with slit-shaped irrigation ports (4) in the lateral direction.
[0007]
In addition, in this irrigation pipe (3) (3), a water distribution pipe (9) whose upper surface is open to a large number of water distribution ports (8) is inserted, and the water distribution pipe (9) One end of the feed pipe (10) connected to the discharge port of the pump (P) activated by the electric motor is connected, and the other end is closed by the stopper (11). In the middle, a water amount adjusting valve (12), a water pressure gauge (13), a stop cock (14), (14), etc. are provided, and (15) shows a water absorption pipe of the pump (P).
[0008]
Now, when the pump (P) is started by the electric motor, water is fed from the feed pipe (10) into the water distribution pipe (9) as shown by arrows (b) in FIG. 4 and FIG. (8) ... goes out like (c) and flows down as shown in (d) and falls from the irrigation port (4), but air enters the irrigation pipe (3). In a certain state, that is, when the water does not fill the irrigation pipe (3), the water coming out from the slit-shaped irrigation port (4) has a cut (b) as shown in the figure due to the surface tension, and is completely membrane-shaped. It does not become.
[0009]
Therefore, at the start of irrigation, the pump (P) is rotated at a higher speed, and the water amount adjustment valve (12) is turned to increase the amount of feed from the distribution pipe (9) to the irrigation pipe (3). is there. If it does so, the air in the irrigation pipe (3) will be rapidly discharged | emitted and water will be filled, and the water which comes out from an irrigation port (4) will become a film-like thing without a cut | interruption (b).
[0010]
Therefore, when the water amount adjusting valve (12) is rotated in the reverse direction to reduce the amount of water fed to a value suitable for the predetermined amount of irrigation, normal water without a break (b) from the irrigation port (4) as shown in FIG. A necessary amount of the irrigation membrane (a) is generated, and an appropriate amount of water is evenly irrigated to the soil in the seeding box (2) transported in the transport passage (1).
[0011]
Further, in order to generate the normal required amount of the irrigation membrane (a), it may be generated by increasing the number of rotations of the pump (P) and adjusting the amount of water by the water amount adjustment valve (12) as described above. However, the power source and the electric motor are connected via an inverter, and when the pump (P) is started, that is, when the electric motor is started [water coming out of the irrigation port (4) is broken (b) For a few seconds until it becomes a non-film-like thing], the number of rotations is increased, and after the start-up, the number of rotations of the electric motor is automatically restored to the number of rotations that feeds a predetermined amount of irrigation. It saves time and effort.
[0012]
In addition, what is shown in FIG. 6 is a seeder that is installed on the seeding frame (7) and seeds the seeding box (2) after irrigation that is transported in the transport passage (1). The feeding groove (18) formed in the axial direction of the feeding roll (17) by rotation of the feeding roll (17) in the (e) direction from the supply hopper (16). The particles that are fed out are guided downward by the guide material (19) and fall so as to be seeded, and the excess particles out of those fed from the supply hopper (16) are weired by the plate-like brush (20). What is stopped and returned by the large rotating brush (21) and does not fall from the feeding groove (18) is removed by the small rotating brush (22).
[0013]
As shown in FIG. 7, the feeding groove (18) of the feeding roll (17) has a scraping surface (23) from the peripheral surface toward the shaft core and a take-up surface provided on the scraping surface (23). The angle (α) between the surface (24) and the surface (24) is set to 45 degrees, and they are arranged in the horizontal direction to improve the fit of the particles into the feeding groove (18) and the removal by the small rotating brush (22).
[0014]
