Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a submerged soil direct seeder.

[Conventional technology]

The ultimate purpose of the direct sowing machine in water-immersive soil is to improve the productivity by the final method of rice cultivation based on the primitive idea of directly seeding and harvesting seed paddy on the paddy field. The seeds are then sown on the surface of the cultivated soil with a certain hardness and coated with chemicals.However, it is very difficult to completely drain the water. Good regulation of falling water conditions is strict, and in rainy weather it may take time and effort to drop water and it may not be possible to sow at the scheduled date and time.This is due to the structure of the machine and most of the direct seeding machines on the market have seeding grooves. In the place where the rice seeds are dropped and applied in a soil-filling method, the seeding ditch can be made by the weight of the machine in the place where the water completely drains, but if the soil is hard, the soil cannot be formed, and the coated rice seeds can be clearly seen and the water can be collected. At the moment, the muddy water of the paddy soil was concentrated in the sowing groove, and due to the foaming phenomenon of the coating agent, it was exposed a few days after the seeding was completed and irrigated. Up to
There is no abnormal growth, but as I attend the school, I fall asleep and lose revenue. In the current mechanized era, rice crops were mowed and threshed at the same time, and due to the improvement of varieties that are resistant to lodging, the cultivation of them, and the cultivation method are instructed, the yield loss due to lodging is inevitable. I must avoid it.

[Problems to be solved by the device]

The seeds grow buds in the presence of water, but the roots do not grow in the absence of oxygen.The seeds rot even if they sprout. After rooting and growing, water is forbidden until the seeds land, so seed seeds are made and the seeds are dropped into the seedlings, but when it is deep, it is supplied before buds emerge on the ground. Position the seed pad within the ideal 8 to 15 mm below the ground surface, where oxygen will be lost and will rot, and if it is shallow, it will fall and yield will be lost. Muddy water does not flow into the bottom of the float that slides along the flooded paddy field, seed rice does not float or move, and it is ideal for point rice seeding because it is difficult to manage rice cultivation, and there are some divisions depending on the variety, large and small grains. Variety The first step to select and select the appropriate number of grains is, as far as the appearance is concerned, it is a compact cylindrical seed tank that has no complicated projections, and has no fear of watering in the lower part of the tank. In the second-stage seed coating device, we would like to accurately position and coat by spotted seeding.

[Means for solving the problem]

The seed paddy in the cylindrical seed tank is constantly placed in the arc-shaped streak hole on the outer periphery of the bottom surface, and under the arc-shaped streak hole, a fan-shaped open / close plate for opening and closing the streak hole is closely attached. Is provided with a seed feeding part that acts on the start, stop, and pause of the sowing work, which is in close contact with the fan-shaped opening and closing plate and is driven to rotate.The seed feeding part has an upper part and a lower part in close contact with each other. There are multiple holes that penetrate vertically, the upper part is finely slid in the circumferential direction to adjust the size of the through holes, and the holes act to select the number of seeds to be sown, such as large and small grain varieties. An annular plate provided with seed drop openings at two positions 180 ° apart is fixed in a tightly contacted state underneath, and there is an open / close valve that opens and closes the seed drop openings. In the case of, the start / stop / pause of sowing can be done in units of 1 or 2 From now on, in the case of sowing rice fields and curves, waste sowing will be reduced by that much (even in the case of the current rice planting machines, seedlings are used more than the standard for small rice fields with deformation of rice fields etc.). The seed coating device has openings at the top and bottom of the peripheral surface, and is provided with a cylindrical covering member and a number of rotors that rotate by guides along its inner peripheral surface. When it comes to the upper part inside the shape-covering member, the rotor retracts to form the seed receiving recess, and when the received seed moves to the lower end, the rotor pushes the seed pad between 8 and 15 mm below the bottom of the float, resulting in point seeding. The surface is specified as the bottom surface of the float, and the seed paddy can be positioned accurately. This is the first condition for ensuring the germination rate and increasing the yield.

〔Example〕

Circular streak holes (1,1) on the bottom of the cylindrical seed tank (A)
However, the seed paddy in the tank is located in both sides facing each other, and is constantly trapped in the streak hole. Below this arc-shaped streak hole, there is a fan-shaped opening / closing plate (2, 2) that opens and closes the streak hole. ,
By opening and closing this opening and closing plate 90 degrees in the circumferential direction, the streak holes on both sides are opened and closed at the same time, and it acts under the fan-shaped opening and closing plate that adjusts the seed paddy supply amount and starts, stops, and pauses the seeding work. A seed feeding part (B) which is driven to rotate is provided, and this seed feeding part is provided with an upper part (3) and a lower part (4).
Both are slidably in close contact with each other, each of which is provided with a plurality of vertically penetrating holes (5, 5), and by finely sliding the upper part (3) in the circumferential direction, the seed The hole that penetrates the feeding section can be adjusted to large or small, which works to select the appropriate number of grains considering the number of divisions, large and small grain varieties, etc. Furthermore, below the seed feeding section, both sides 18
An annular plate (C) provided with seed drop ports (6, 6) is closely adhered and fixed independently at two places 0 ° apart, and there is a seed drop port opening / closing valve (7, 7). The seeds are trapped in the holes (5, 5) that pass through them when they pass through the arc-shaped streak holes, and the seeds that enter the holes fall at the seed drop openings to become empty holes. A seed applicator (D) is provided below the seed drop opening, which is repeatedly received, and the seed applicator is a cylindrical covering member having openings (8, 8) in upper and lower peripheral surfaces, and A large number of rotors (9, 9) that move and rotate along the inner peripheral surface, and when the rotor reaches the upper part (8) of the cylindrical covering member, the rotor retracts to form a seed receiving recess, and the received seed When the rotor moves to the lower end (8), the rotor disperses the seeds and floats (E).
It is characterized by comprising a guide body (F) for guiding the rotor so as to push it out between the bottom of the bottom and 8-15 mm.
The seed-applying device is associated with the float, and moves finely up and down with respect to the bottom surface of the float, so that
It is a direct sowing machine for submerged soil that can identify millimeters.

[Effect of device]

The seed feeding device is in a state of being in close contact with the bottom of the seed tank, which has only a cylindrical shape without complicated protrusions on the outer shape, and the seed paddy is pushed out at the bottom of the float and positioned and coated between 8 and 15 mm below the ground surface. Not to mention the simplification and miniaturization of the outer shape, the rationality of embedding seed pad in place at the same point while sliding on the ground surface at the bottom of the float cannot be overlooked. Recently, non-tillage cultivation methods for paddy rice have also appeared, but the significance of paddy fields that can cope with all natural conditions is immeasurable. In view of the characteristics of paddy rice in the area, unfortunately it is easy to be damaged by drought, so the direct seeding cultivation of paddy rice based on the primitive idea has great significance. In this project, the direct sowing machine for water-immersive soil seeks not only to improve productivity but also to increase the yield, with the primary goal of ensuring and improving the germination rate.
