Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sowing tractor for sowing seeds such as vegetables and cereals while ridges are laid on farmland, and a sowing apparatus used by being mounted on the tractor.

[0002]

2. Description of the Related Art It is well known that agricultural tractors having various functions have been conventionally developed, which greatly contributes to labor saving in agriculture. An overview of the steps of the seeding and raising work using such a conventional agricultural tractor is as follows.

[0003] First, in the first step, weeding is carried out while digging the farmland by cultivating the farmland with a cultivator equipped with a rotary blade having a relatively large pitch dedicated to the raising of the farmland. Next, in the second step, the tractor is equipped with a ridge raising device consisting of a rotary tilling blade for soil cultivation having a relatively small pitch rotary blade and a ridge tool for forming a ridge by raising the cultivation soil from both sides to the center. A ridge is formed while finely crushing the above-mentioned rough soil mass. Since the process up to this point is heavy labor, it is mechanized by an agricultural tractor.

Next, as a third step, a middle groove is cut into the ridge to form two small ridges with a relatively wide ridge sandwiching the middle groove. Subsequently, in a fourth step, the center of the small ridge is formed. A sowing operation for sowing a predetermined amount of seeds is performed, and then, as a fifth step, fertilizer is applied to the sulcus, and when germination occurs, a thinning operation is performed as a sixth step to restrict growing seedlings. Of these third to sixth steps, the sowing work of the fourth step may be mechanized by a tractor equipped with a sowing device, but in a normal farm, these third to sixth steps are performed manually. It is usually done. In the case where a narrow ridge is formed in the second step (ridge work), the third step (middle grooving work) is omitted, and in the fifth step (fertilization work), fertilizer is filled in the grooves between the ridges. They may be sprayed.

[0005]

As described above, in the conventional first step (raising operation) to sixth step (thinning operation), the tilling operation as a preparation operation before the seeding operation is mechanized. In the subsequent process, although devices each having a single function (for example, a sowing device) have been developed and sold, it is relatively light work compared to tilling work.
Since all mechanization requires huge capital investment,
The fact is that active mechanization has not progressed.

[0006] Conventional mechanization "makes agricultural work easier".
Therefore, there is no mechanized idea from the viewpoint of agricultural products such as "creating delicious crops" or "increase the yield". For example, in the second step (ridge setting work), the ridge is raised to form a ridge, and in order to maintain the shape of the ridge cleanly, the side surface of the ridge is strongly pressed, so that a clean ridge is visually apparent. Is formed,
The air permeability from the ridge side surface worsens. Also, even when performing the third step (middle groove cutting work), in the middle groove cutting using a dedicated medium groove cutting device, a beautiful streak-shaped middle groove is formed on the side surface of the middle groove that is hard to collapse due to pressing, Similarly, the air permeability is poor and the absorption of fertilizer from the side walls is also poor.

Further, in the fourth step (seeding operation), a method of embedding a predetermined amount of seeds at a predetermined interval in a cultivation soil, covering the soil thereon, and performing a soil covering process is general. That is, the seeds are buried in the soil several cm below the ground surface and shielded from sunlight, and germinate in the soil without receiving sunlight (hereinafter referred to as "dark germination" in the present invention). Referring to FIG. 6 showing the state of the dark germination over time, first, as shown in FIG.
embedded at a position of about m. Next, the radicle 53 which germinated and emerged from the seed as shown in FIG.
Starts to grow toward the ground surface from a position several centimeters in the soil. Therefore, the cotyledons 54 in the early stage of germination are white because they cannot be photosynthesized in the soil and start growing mainly by the nutrients held by the seeds, and the radicles 53 are necessary for growth. It tends to grow roots deep underground in search of nitrogen content.

Next, as shown in FIG. 1C, the cotyledons 54 appear on the surface of the ground and become bifoliates 55 (in the case of dicotyledons; the same applies hereinafter), while the radicles 53 grow deep in the soil. Main root 5
6 and many lateral roots 57 are grown laterally at the same time.
Next, as shown in FIG.
9 are generated and grown one after another, but in this state, the two leaves 55 are withered and are in a state of waiting for fallen leaves. That is, Futaba 55
Supplies its own nutrients for the growth of the growth point 60 and the growth of the roots 56, and follows its own destiny.

[0009] Incidentally, nutrients in the soil basically infiltrate from the surface of the earth, and do not spring up from underground. However, in conventional dark germination, the seeds 20 are buried and sown at a depth of several centimeters below ground, so that the resulting roots 56 are required for growing underground with less nutrients according to the essential characteristics of the roots. The side root 57, which is a nitrogen-absorbing root, grows by obtaining the nitrogen content. Therefore,
Even if organic fertilizer is sprayed on the ground, it will be decomposed by aerobic bacteria near the ground and will be absorbed into the root hair only after being transported into the soil by water supplied from the ground, but the root itself will absorb nitrogen. Since the roots are growing preferentially, the amount of nitrogen absorption increases, and the appearance of a tall plant and the steady growth of green leaf-grown stems are observed, but the phosphorus absorption required for fruit growth is observed. Since the growth of the roots is not coordinated with the growth of the nitrogen-absorbing roots, the roots are inferior in the ability to absorb phosphorus, and there is a problem in the growth of fruits.

On the other hand, as a germination method for solving the above-mentioned problem of dark germination, there is a "light germination" method which has been researched and developed by the present inventors and further verified by a field test. In this light germination method, seeds are sown on the ground surface to germinate in the presence of sunlight, and the roots are grown near the ground surface, which is rich in nutrients and sterilized by ultraviolet rays in sunlight, to absorb phosphorus. It is a new method to form a balanced rhizosphere between roots and nitrogen-absorbing roots. This light germination will be described with reference to FIG. 5 which shows the change of germination with time. First, the seed 20 is sown on the surface of the soil 23 as shown in FIG. The seeds 20 germinate on the ground surface and buds 54
The radicles 53 generated at the same time as starting to grow start underground according to the characteristics.

Next, as shown in FIG. 1C, the radicle grows underground to form a main root 56. In the process,
In the “oxidized layer A” near the surface (surface layer having a depth of about 3 to 5 cm from the surface, which has good air circulation and has a sterilizing effect by ultraviolet rays of sunlight), the main root 56 Root hairs 58 extend laterally from. This root hair 58
Are root hairs that do not exist in the aforementioned dark germination. In the portion of the oxidized layer A, nutrients generated by the decomposition of various organic substances near the ground surface by aerobic bacteria penetrate first with water, and are rich in air permeability, less germs, phosphates, etc. Because it is rich in nutrients necessary for fruit growth
The root hairs 58 can efficiently absorb phosphorus that is essential for growing the fruit. The main root 56 is located in the “reduced layer B” below the oxidized layer (the area where the flow of air is small and the decomposition of microorganisms mainly by anaerobic bacteria progresses, and the fertilizer component is rich in nitrogen component). Lateral roots 57 for mainly absorbing nitrogen grow in the reduced layer B. By the way, the aforementioned "dark germination"
6, the seed 20 is usually buried near the boundary between the oxidized layer A and the reduced layer B to germinate. Therefore, when germinated, the main root 56 is straightened below the reduced layer. Few root hairs extend into B and extend laterally within oxide layer A.

Furthermore, in the case of light germination, the foliage 55 produced by germination grows in the sunlight, so that photosynthesis by the foliage 55 is also started, and the nutrients necessary for the growth at the early stage of germination are as follows. In addition to the nutrients originally held by the seeds, Futaba 55
Will also be supplied by photosynthesis. As a result, as shown in FIG. 3D, it has been found that even if new leaves 59 are generated one after another, the bi-leaves 55 are still withered and continue photosynthesis without wilt. This is in contrast to the case of dark germination in which Futaba 55 withers quickly.

[0013] Incidentally, the conventional sowing apparatus is a method in which seeds are buried in the ground, and there is no sowing apparatus suitable for such a light germination method. Also, in the conventional sowing device,
Since there is a large amount of seeding in one place of the seeding part, inconsistent work of thinning out seedlings that have germinated in order to leave only an appropriate number of seedlings after they germinate is necessary.

The present invention has been made in view of the above-mentioned various problems, and has as its first object to solve these problems, and to provide a new seeding apparatus suitable for a light germination method.
It is a second object of the present invention to provide a sowing tractor that enables the various processes of sowing and raising seedlings to be performed at once by one machine, thereby enabling significant labor saving and labor saving. The third object is to omit (thinning work) and to perform a rational sowing operation with a low seeding amount, and in addition, a sowing tractor from the viewpoint of "delicious and high yield" from the viewpoint of agricultural products. The purpose is to provide.

[0015]

Means for Solving the Problems The present invention has been made to achieve the above object, and its basic idea is to germinate seeds in place of conventional "dark germination",
Seeds are sown on the ground surface to germinate in the presence of sunlight, and the roots are grown near the ground surface, which is rich in nutrients and sterilized by ultraviolet light in sunlight, to absorb phosphorus and nitrogen. Adopting `` light germination '' to form a well-balanced rhizosphere, it relates to a seeding device for realizing this idea, specifically, at least, tillage means with a rotary plow blade, A furrowing means for furrowing the soil plowed by the tilling means, a sowing means for sowing at a predetermined interval on the surface of the furrow formed by the furrowing means, and a sowing part on the surface of the furrow. A sowing tractor comprising a moving pressure roller, and the tilling means, the ridge means, the sowing means, and the presser roller being mounted on a single vehicle body. Thereby, the second step (ridge work) and the fourth step (seeding work), which are indispensable for the above-mentioned light germination method, can be performed by one tractor, and the seeding amount in the seeding means does not need to be thinned out. If it is set to the amount, the above-described sixth step (thinning-out work) can be omitted.

In a preferred embodiment of the tractor, a grooving means for forming a middle groove in the center while discharging the soil at the center of the ridge to the left and right is disposed at the rear center of the ridge means. While dividing the ridge into two small ridges on the left and right, while mounting a fertilizer application means for spraying a predetermined amount of organic fertilizer in the middle groove, the seeding means and the presser roller,
There is a configuration in which a pair is arranged so as to be adjustable for each small ridge. In this case, the third step (middle groove cutting operation) and the fifth step (fertilizer application operation) can be simultaneously performed by one tractor.

In another embodiment, a dispensing means for spraying a predetermined amount of a pesticide on a sowing portion is disposed behind the sowing means, so that the method can be carried out simultaneously with the spraying of the pesticide. Become. In this case, the pesticide is preferably granular, and the sowing means and the dosing means are operated synchronously to spray the pesticide at or near the seeding position, thereby reducing the amount of the pesticide sprayed. Is a preferred embodiment.

Further, the fertilizer to be sprayed by the fertilizer is used as an organic fertilizer, and in particular, one or more of pig dung and chicken dung rich in a phosphorus component or an organic fertilizer obtained by mixing a plant pulverized material with the dung is used. preferable.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view of a main part showing an example of a sowing tractor according to the present invention, and FIG. 2 is a left side view of a main part of FIG. 1 and 2, at the rear of the self-propelled tractor body 30, a tilling device 1 having a rotary blade 1a is disposed, and at a rear portion, a ridger 2 composed of a pair of plate-like bodies is disposed. The groove cutting means 5 is arranged at the center position, and further on the rear side, a pair of rolling rollers 8, seeding means 3, dosing means 7 and pressing rollers 4 having projections 8a around the periphery are arranged, respectively. Is held by the tractor body 30 by support members 31 and 32 extending rearward from the body 30 and holding frames 34 and 35 held by the support members 31 and 32.

The tilling means 1 is provided with a tilling blade 1a for cultivating soil at a relatively small pitch, and rotates the rotary shaft 1b by power from a vehicle body driving source to rotate the tilling blade 1a to turn the agricultural land into cultivated soil. It plays the role of plowing finely as appropriate. It is needless to say that prior to the cultivation cultivation by the cultivation means 1, the farmland is roughened and weeds are dug up as necessary.

Next, the ridge raising means 2 raises the cultivated soil finely cultivated by the tilling means 1 from right and left by a pair of left and right working plates 2a to form ridges, and the lower end of the cover 1c of the tilling means 1. This is a member in which the ridge surface is formed in a uniform plane by the leveling plate 2b arranged in the portion, and a relatively wide ridge 11 is formed between a pair of ridges 24 as shown in FIG. It is formed one by one. In the conventional ridger, as shown in FIG. 4A, the angle θ1 with respect to the traveling direction of the work board 2a (the direction of the arrow in the figure) is set to be large, and many surrounding soils are ridged. By collecting them inside and pressing them on both slopes 11c of the ridges, a visually beautiful ridge is formed. However, in the present invention, as shown in FIG. Is set relatively small (θ2 <θ1), whereby the pressing force of the work plate 2a on the ridge slope 11c is reduced. As a result, the side surface of the ridge formed by the ridge means used in the present invention is more air-permeable than the conventional one.

Next, the groove cutting means 5 is provided with a shallow middle groove 1 at the center of a relatively wide ridge 11 formed by the ridge means 2.
2 is a member that divides the wide ridge 11 into a pair of left and right small ridges 11a and 11b sandwiching the middle groove 12. The earth discharging member 5a having a pointed tip-like shape is used as the support member 32. Are held by fixing means 33 such as bolts. The fixing means 33 can adjust and fix the position of the earth discharging member 5a in the vertical direction and the horizontal direction as appropriate, so that the depth and position of the middle groove 12 can be adjusted. In the present invention, too, the soil is not pressed against both slopes of the middle groove 12 (see FIG. 3) to form the middle groove, but the soil existing mainly in the middle groove forming position is discharged to both sides to form the middle groove 12. In addition, the shape of the discharging member 5a is devised. Therefore, both slopes of the middle groove are also soils with high air permeability.

Next, as shown in FIG. 2, the rolling roller 8, the seeding means 3, the dosing means 7, and the pressing roller 4 are integrally formed by a pair of left and right holding frames 34, 35 fixed to the support member 32. The holding frame 34 is held at intervals between the holding frames 35.
Can be freely adjusted depending on the mounting position on the support member 32. That is, since the holding frame 35 is slidably mounted on the support member 32 and is fixed in position by the set screw 36, the spacing is appropriately determined according to the ridge width and the seeding position on the ridge surface. Can be adjusted.

The rolling roller 8 is a roller that freely rotates about a rotation shaft 8b disposed at the lower end of the holding frame 35. The height of the rolling roller 8 from the support member 32 is adjusted by a retaining pin 35.
It can be freely adjusted by a or the like. Further, a plurality of projections 8a are formed to protrude from the outer surface of the rolling roller 8, and when the tractor advances in the direction of the arrow in the figure, the projections 8a bite into the cultivation soil 23 to rotate the roller 8.
A first gear 13 is mounted on the rotating shaft 8b and rotates with the rotation of the roller 8. This rotating force is applied to the seeding means 3 and the dosing means 7 to be described later via a chain 15 mounted on the gear 13. As the drive source.

Next, the sowing means 3 comprises a hopper 3a for storing the seeds 20, a rotary seed discharging member 3b disposed below the hopper, and a cylindrical guide for guiding the discharged seeds to a ridge. It comprises a member 3c and a shielding member 3d as a wind shield that covers the periphery of the seed so that the seeds falling on the ridge surface or the seeds 20 that have fallen are not blown off by the wind. Here, the rotary seed discharging member 3b includes a rotary shaft 3e rotatably held by the holding frame 34, and the rotary shaft 3e
The rotating body is formed of a cylindrical rotating body having recesses 3f formed at predetermined intervals on the outer circumferential surface, and the rotation of the rotating body intermittently discharges only seeds that have fallen into the recesses 3f on the outer circumferential surface. Has become. A second gear 14 is coaxially arranged on the rotating shaft 3e. The second gear 14 is connected to the first gear 13 of the rolling roller 8 by a chain 15, and the rolling of the rolling roller 8 is performed. The seed discharging member 3b also rotates in synchronism with this, and as a result, the seeds drop intermittently on the cultivation surface.

Next, the dosing means 7 is for dispersing the slow-acting granular pesticide 21 in the vicinity of the seed 20 which has fallen on the ridge surface, and is disposed at a hopper 7a for storing the particulate pesticide and at a lower portion of the hopper. It comprises a rotary pesticide discharge member 7b and a cylindrical guide member 7c for dropping and guiding the discharged pesticide 21 to the vicinity of the seeding position surrounded by the shielding member 3d of the seeding means 3. Here, the rotary pesticide discharging member 7b is rotatably held by a holding frame 34 on a rotating shaft 7f.
The rotation shaft 7f has concave portions 7 at predetermined intervals on the outer peripheral surface.
d is formed, and only the particles that have fallen into the concave portion 7d on the outer peripheral surface due to the rotation of the rotating body are intermittently discharged. A third gear 16 is coaxially arranged on the rotating shaft 7f, and the third gear 16 is connected to a fourth gear 18 coaxially arranged with the second gear 14 of the seeding means 3 by a chain 17. Has been
Accordingly, the rotary pesticide discharging member 7b rotates together with the seed discharging member 3b in synchronization with the rolling of the rolling roller 8, and as a result, the granular pesticide is intermittently sprayed near the seeding position. Has become.

The rotary pesticide discharging member 7b may be rotated by the first gear 1 of the rolling roller 8 in addition to the above method.
3, the second gear 14 of the rotary seed discharging member 3b and the third gear 16 of the rotary pesticide discharging member 7b may be connected by a single chain so as to rotate synchronously.
Adjustment of the seeding interval is performed by adjusting the first gear 13 and the second gear 1.
4 can be easily changed by appropriately adjusting the gear ratio. Specifically, the first gear 13 is fixed, and the second gear 14 of the seeding means 3 is replaced. In this case, since the pesticide spraying interval and the sowing interval of the administration means 7 must be the same, when changing the sowing interval,
It goes without saying that the third gear 16 also needs to be replaced at the same time.

Next, the pressure reducing roller 4 is loosely fitted and held on the rotating shaft 4a mounted on the holding frame 34, and the roller is freely rotated by frictional resistance with the ridge surface. ing. The pressure-reducing roller 4 presses the seeds 20 that have simply fallen naturally onto the ridge surface by the weight of the rollers to hold the seeds firmly on the soil cultivation surface. And to prevent them from being washed away by a slight amount of rain. In order to increase the settling pressure, if the joint between the holding frame 35 and the holding frame 34 is rotatably joined by the rotation shaft 8 b of the rolling roller 8, the seeding means 3 and the drug are not administered. Since the total weight of the means 7, the pressure reducing roller 4, and the holding frame 34 is held by the rolling roller 8 and the pressure reducing roller 4,
It is possible to increase the settling pressure as compared with the case where only the weight of the settling roller 4 is used.

Next, reference numeral 6 in FIG. 1 denotes a fertilizing means.
Since the drawing becomes complicated, only the positions are indicated by dotted lines. The fertilizing means 6 is provided with the medium groove 12 simultaneously with the seeding operation.
And a hopper 6a for storing the organic fertilizer 13, a discharge mechanism for the fertilizer, and a cylindrical guide for guiding the fertilizer to the middle groove. 6d. The discharge mechanism used here has the same structure as the above-mentioned rotary seed discharge member 3b and rotary pesticide discharge member 7b, and it is possible to rotate the rotary member with an appropriate power source. Since there is no need to intermittently spray, it is possible to adopt a method in which the hopper 6a is continuously dropped freely through the discharge port and the cylindrical guide member 6d.

As the organic fertilizer, those containing a large amount of a phosphoric acid component, such as crushed pig manure and chicken manure, are preferable.
In addition, as described in JP-A-8-253385, plant fibers such as bamboo, rice hulls and weeds are crushed while pressurizing with a rotary screw to crush the plant fibers. Is also a preferred organic fertilizer.

These organic fertilizers have no immediate effect as fertilizers themselves, and become effective fertilizers only after being decomposed by aerobic bacteria. The natural decomposition takes several weeks, so that seeding is not possible. Even if fertilization is applied at the same time, plants will start to break down and penetrate into the ground when fertilizer is needed.

Further, as shown in FIG. 3, the above-mentioned ground plant 25 is sprayed on the upper surface of the settled seed 20,
It is also a preferable method to prevent the seeds exposed on the ground surface from drying due to the moderate water retention of the ground plant 25, which has the effect of reducing the frequency of watering after sowing and also favors the ground plant itself. Since it is decomposed by the temper bacterium to become fertilizer, it is expected that the labor for dispersing the fertilizer is reduced.
In this sense, in the present invention, a suitable second fertilizing means (not shown) is disposed at the rear of the pressure reducing roller 4 so that the seeding part is covered with the ground plant 25. Is also a preferred embodiment.

The above explanation is based on the fact that one center of one wide ridge 11 is
A pair of left and right small ridges 11a, 11b
Although it is an example of forming the ridge, it is also possible to form two or more intermediate grooves in one wide ridge to form three or more small ridges. 5, a plurality of rolling rollers 8, seeding means 3, and pressure reducing rollers 4
, Etc., will be installed in multiple units. Conversely, when the seeding work is performed by ridged one by one without forming the middle groove, the groove cutting means 5 is unnecessary, and the fertilization means 6 in this case uses the organic fertilizer in the ridge 24. It will be scattered.

In the example shown in the drawings, the tilling means 1, the ridge means 2, the grooving means 5, the rolling roller 8, the seeding means 3, the dosing means 7, the pressure reducing roller 4, and the fertilizing means 6 are integrally mounted. Although a tractor for sowing is illustrated, essential components for realizing the light germination method intended by the present invention include tilling means 1, ridge means 2, sowing means 3, and pressure reducing roller 4. Therefore, it is a simple method to form a seeding tractor on which only these are mounted. In this case,
If necessary, the tractor equipped with the grooving means 5 and the fertilizing means 6 performs grooving and fertilization, and further performs pesticide spraying as appropriate.

Since the basic structure of the seeding apparatus of the present invention is the ridge means 2, the seeding means 3, and the pressure reducing roller 4, these are integrally held to form a seeding apparatus. It is also possible to perform sowing while tilling or ridged on the farmland after tilling by mounting it on a tractor.

[0036]

As described above, according to the present invention, it is possible not only to mechanically perform seeding based on an unconventional light germination method, but also to achieve "delicious fruit" and "increase in yield". It is to bring about agricultural machinery from a new perspective,
The historical significance of agricultural machinery is significant.

In particular, since the light germination method can be mechanized, crops can be cultivated on a large scale by the light germination method, and a large amount of delicious fruits can be produced. It is expected to be a great gospel.

Furthermore, since traditional phosphate-based natural fertilizers such as chicken dung and pig dung are used as fertilizers, there is no occurrence of soil damage caused by the use of chemical fertilizers, and stable production of safe crops is ensured. The effects of the present invention are different from those of mere agricultural machines aimed at labor saving and labor saving, and promote a new shift to agriculture, and their social effects are immeasurable. is there.
