Description

  The present invention is a plow working machine with a soil repellent plate with a soil repellent plate, and at the same time as plowing work, a portion deeper than the plow floor is excavated and released by a soil soil repellent plate with a soil repellent plate. The present invention relates to a bottom plow working machine capable of improving water permeability and partially expanding a soil formation layer.

  According to the English-Japanese-Japanese Agricultural Machinery Glossary (supervised by Takeo Kashiwagi, published by Shinnobu Hayashi Co., Ltd.), “Plow” is a tool that pulls and cultivates with livestock or mechanical power. A farming tool that was formerly called a Western-style rice, developed in Europe and the United States, and cultivates and reverses soil, depending on the structure, bottom plows, disc plows, rotary plows, and the number of main bodies. There is a mutual use. " The present application proposes a subsoil cage having a subsoil trench improvement function that can be attached to all the above-mentioned plows.

In general, the soil that is plowed by plow is translated as plow layer. According to the English-Japanese-Japanese-English Agricultural Machinery Terminology, Plow layer (soil) is also called “cultivated soil, located at the top of the soil, for cultivation of crops, cultivation, fertilization, supervision, etc., rich in nutrients, "The most important soil for growing crops."

And the soil under the soil is called the mental soil. According to the English-Japanese-Japanese-English Agricultural Machinery Glossary, “subsoil” is a layer below the surface soil, insufficiently weathered and dense soil that does not contain organic matter. Usually, the nutrients on the surface layer are washed away, although there are few nutrients. In that case, subsoil cultivation has a great effect of improving soil. "

Also, according to the dictionary, subsoil plowing means that “when plowing only the soil on the surface, the subsoil structure is often deteriorated, so Tillage of soil. Improves air permeability, water retention, water permeability, etc. "

Furthermore, according to the dictionary, the 床 (犂) floor has two meanings, Plow sole as a part of plow and Sole as part of soil.
It is pan. The Plow sole- 鋤 (犂) floor is "at the bottom of the skeleton and supports the lateral pressure that occurs when plowing and reversing the soil, and also keeps the posture of the cocoon and stability in the forward direction." pan-floor bed "Also known as cultivator, bottom bed, slab bed, etc., hard soil layer of several centimeters thick that can be made 10-20 cm below ground by long-lasting treads of plows, plows, tractors and other agricultural machines, to prevent water leakage While effective, there are also obstacles such as poor ventilation. " In this application, it is mainly used as the meaning of Plow sole.

The working machine of this application aims at performing subsoil plowing simultaneously with plowing the plowing by plow. In this case, the component that performs subsoil plowing is generally referred to as subsoil crushing (sindhasari) or subsoil. In this application, it will be unified with the spirit. In the past, when the soil treading pressure due to running of the tractor was not desirable as shown in FIG. 20, the subsoil cage often pointed to a kind of small hearth blade used to eliminate local compaction. However, in recent years, it has been further developed, and Japanese Utility Model Publications 58-68801 and Japanese Utility Model 4-35213 have been proposed for the purpose of plowing and subsoil cultivation.

The mechanism for subsoil cultivation at the same time as plowing is described in Japanese Utility Model Publication No. 58-68801 and Japanese Utility Model Publication No. 4-35213. The subsoil was crushed and softened by the method of towing it by inserting it into a layer, but generally the traction resistance was large and efficient work could not be done.
Japanese Utility Model Publication No.58-68801 Japanese Utility Model Publication No. 4-35213 JP-A-9-322601 Agricultural machinery terminology Supervision by Takeo Kashiwagi Shinnorinsha Co., Ltd. Published in 1994

As shown in FIG. 20, the subsoil 90 attached to the conventional plow crushes the subsoil layer compressed by the treading pressure of the tractor tire 91 and softens it, and the treading pressure makes the drainage of the subsoil layer worsen. It is used to prevent, and even crush the subsoil layer to improve physical properties and soften it. In addition, as shown in this figure, a normal tractor drops one tire into a gravel groove made of plowing, and the other pulls the plow working machine in an oblique state placed on the uncultivated surface. It is.

In general, the subsoil has a knife-like shape like the subsoil 93 of FIGS. 13, 14 and 15, and the subsoil 95 of FIG. 21, but when inserted into the ground and pulled, The side pressure applied from the top, bottom, left, and right is large, and until now, strong traction was required. In order to reduce the traction resistance of the knife-like blades 93 and 95, a blade 96 of a subsoiler working machine in which a soil repellent plate 97 is attached to the front edge of the beam is proposed as disclosed in JP-A-9-322601 described in FIG. ing.

Rather than pulling the knife-like blades 93 and 95 inserted into the subsoil layer, a chisel 98 and a soil repellent plate 97 are attached along the front edge of the beam, and the subsoil is excavated and raised to release it to the surface. It has been empirically found that the soil-repellent plate-like subsoiler blade 96 requires less traction. In this application, this is used to propose a new subsoil having a reduced traction resistance compared to the conventional knife-type subsoils 93 and 95.

  However, even if the traction resistance is reduced, the soil repellent plate subsoiler working machine 96 as disclosed in JP-A-9-322601 has a structure that raises the subsoil and releases it to the ground surface. On one side, grooves are formed in the subsoil layer, so that the water permeability lasts for a long time and the top soil falls into the subsoil layer and mixes with it, but it also improves the subsoil layer, but the soil with less nutrients is released to the surface. If it is crushed, the unevenness becomes severe, making it difficult to carry out post-work and possibly causing a decrease in revenue.

In the present invention, a beam extending downward is attached to the rear part of the plow work machine or to the release side or the front side, and a chisel at a position deeper than the floor and a soil repellent board are attached to the lower end of the beam. The soil raised by the chisel is dissipated into the gravel groove by a soil repellent plate, and as shown in JP-A-9-322601, traction resistance is reduced and wear is prevented. By placing the soil in the deeper position in the soil layer by placing the soil cultivated by plowing on the top, the influence of the soil is reduced so that the revenue is not reduced as much as possible.

On the subsoil released into the gravel groove by such a soil-repellent plate-like subsoil, the soil that has been plowed from the next passing frame is covered, preventing the subsoil from coming out on the ground. I was able to do that. Since there is only soil on the ground surface, the possibility of revenue decline is reduced, and a groove for the excluded soil is made in the subsoil layer, and the groove is also filled with the fallen soil in a loose state. A partial thick layer of soil can be created. Grooves filled with soft soil can maintain a water permeability effect over a longer period of time than cracks made with conventional knife-shaped subsoils.

  Since the present invention is a plow working machine provided with a chisel and a soil repellent plate located at a position deeper than the bed at the rear part or the release side or the front side of the box, the subsoil is placed in the gravel groove after the box has passed. Since the soil is covered with the soil on the gravel strip of the subsoil where the next pass is released, the subsoil does not appear on the surface of the earth. One year after ripening and becoming mellow, it is the ideal subsoil improved tillage method that uses the same plowing to put it on the surface for the first time.

In addition, there is little risk of a decrease in revenue, and in the grooves made of earth-repellent plate-like subsoil, the covered soil falls to form a partially thick soil layer and improve the subsoil layer. Furthermore, if the soil is plowed by gradually shifting the position of the soil repellent plate-like subsoil, the whole soil will reach the depth of the tip of the soil repellent plate-like subsoil in the next few years without bringing the subsoil to the surface. It is a cultivation method that can improve the soil layer and create a deep soil layer.

In the present invention, since the earth repellent plate-like subsoil is provided at a position deeper than the bottom reed bed at the rear of the case, the subsoil raised by the earth repellent plate-like subsoil is released into the gravel groove, and thereafter Since the soil is covered by the skeleton that passes through, the subsoil is not exposed to the ground surface, and even if the subsoil is soil that is not sufficiently weathered and does not contain organic matter, it will not cause a decrease in sales.
In addition, traction resistance is reduced in the soil-repellent plate-shaped core soil compared with the conventional knife-shaped core soil. Moreover, since the trench is excavated in the subsoil and backfilled with soft soil, the water permeability effect can be maintained for a longer period than a crack formed in the subsoil layer with a conventional knife-shaped subsoil. Further, if plowing is performed so that the position of the subsoil is shifted little by little every year, the soil layer can be improved to the depth of the tip of the soil repellent plate-like subsoil in the end.

  In the present invention, a groove 60 is formed in the subsoil layer to improve water permeability, and at the same time, the soil is dropped in the groove, and the raised gravel 61 of the subsoil with less organic matter is buried in the soil layer. It is a plow working machine equipped with an earthen reed with earth repellent plate that prevents it from coming out on the ground surface for aging. In addition, a working machine with a smaller traction resistance than the conventional substructures 93 and 95 has been realized.

  1, 2 and 3 are views showing a state where the present invention is attached to the tractor 10 for operation. In the present invention, the tractor 10 is attached and pulled by one upper link 11 and two lower links 12. The upper link 11 is attached to the mast 15 via the upper link pin 13, and the lower link 12 is attached to the mast 15 via the lower link pin 14.

A rear frame 16 is attached to the mast 15. However, a slide mechanism 15a and a rotation mechanism 15b may be interposed between the mast 15 and the rear frame 16. A bottom beam 20 extending downward is attached to the rear frame 16, and a bottom 21 is attached to a lower end portion of the bottom beam 20, and the soil is cultivated and inverted during towing work. There is a coulter 19 in front of the land 21 on the land side 18 of the bottom 21 and cuts the residue such as ridges on the surface and cuts the ground in the vertical direction at the beginning of the work so that the soil is plowed cleanly at the bottom 21 It has become.

A bracket 22 is attached to the bottom beam 20 so as to extend behind the bottom 21, and a subsoil beam 35 is attached to the bracket 22 behind the bottom 21 and extends downward. A chisel 36 is provided at the lower end of the subsoil beam 35, and a soil repellent plate 37 is attached above the chisel 36 so as to raise the soil excavated by the chisel.

As shown in FIGS. 10, 11, and 12, the shape of the earthen reed 30 with the soil repellent plate can be changed according to the quality of the soil and the state of the field. One soil repellent plate from the bottom like the soil repellent plate 39 in FIG. This may be a chisel extended for the same purpose as a soil repellent board, and can reduce the manufacturing cost. The chisel 36 and the soil repellent plate 37 shown in Fig. 11 have a lot of stones, etc. and the tip is worn like a soil repellent plate 39, and the whole must be replaced each time. Since only the chisel 36 or the soil repellent plate 37 can be exchanged, it is economical. The part divided into a plurality of chisel 36 soil repellent plate 34 and soil repellent soil repellent plate 38 in FIG. 12 can be easily replaced, and the topmost soil repellent plate 38 with soil repellent angle can be replaced. By changing the shape to various ones, it is possible to create a low-spreading subsoil 61, or to divide the subsoil into left and right and dissipate it.

7, 8, and 9 are attached to the rear part of the bottom 21 with the earth repellent plate 30 with the soil repellent plate configured as described above. Attach the bracket 22 to the bottom beam 20 and attach the subsoil beam 35 to the tip of the bottom beam 20 so that it extends downward. Raise it to the height of the floor 25 and let it go.

FIG. 16, FIG. 17, FIG. 18, and FIG. 19 compare this action with work diagrams. FIG. 16 is a view of a normal plow work without a heartbeat from the rear. The soil whose bottom 21 is tilled and inverted falls into the gravel groove 63 and becomes like a gravel strip 62 of the soil, and the entire field is tilled and inverted.

The bottoms with the subsoil 93 without the repellent plate are shown in FIGS. A bracket 92 is attached to the rear portion of the bottom 21, and a core soil basket 93 without an L-shaped soil repellent plate extends obliquely downward from the bed 25.
FIG. 17 shows a plowing operation by the bottom 21 to which a conventional subsoil with a subsoil 93 without a soil repellent plate is attached. The gravel groove 63a has a cut portion 66, and the circumference thereof is softened, but the gravel groove 63a is blocked when the tire 91 passes, and the physical property improvement cannot be maintained for a long time was there.

7, 8, and 9 are views of the bottom 21 with the earthen reed 30 with the soil repellent plate of the present invention. FIG. 18 shows the plow operation by the bottom 21 later. The bottom 21 drops the soil in the gravel groove 63b while cultivating and reversing the soil, but the gravel groove 63b lifts the subsoil that was deeper than the anchor bed 25 by the core soil 30 with a soil repellent plate when passing the previous time. And then it was devised and the gravel strips 61 and grooves 60 of the subsoil were made.
The soil plowed by the bottom 21 falls onto the gravel groove 63b, so the groove 60 and the gravel stripe 61 of the subsoil are covered with the gravel stripe 62 of the soil, and in the groove 60, the Soil enters, physical properties are improved, drainage is good, and roots are easy to grow. Minor nutrients are aged until the next plowing in the soil.
However, since the tire 91 of the tractor passes over the gravel groove 63b, the gravel stripe 61 and the groove 60 of the subsoil are somewhat compressed, but the physical improvement is maintained for a longer period than the method of FIG.

FIG. 6 shows an embodiment obtained by further developing the above invention. FIG. 19 shows this work as seen from the rear by a method in which an independent earth repellent plate 30a with a soil repellent plate is attached to the front side of the bottom 21a.
Since the groove 60 of the subsoil layer is made immediately before being plowed and inverted at the bottom 21a, it is not stepped on by the tire 91 of the tractor, and physical improvement can be maintained for a long time. Since the groove 60 and the gravel 61 of the subsoil are stacked and covered with the gravel 62 of the soil, the drainage is better, and the ripening of the gravel 61 of the subsoil is also promoted, and it is abundant in a short time. can do. However, there is a case where the bottom mounting is slightly lowered, the center of gravity is lowered later, and it is impossible to lift up at the U-turn in the headland, or the total length becomes longer and the headland is widely required.

Even if there is a problem with the center of gravity and the total length, multiple bottom repellent plates can be attached by attaching several bottoms in FIGS. 7, 8, and 9 between the cored clay 30a with the repellent plate in FIG. 6 and the bottom 21a. It is also possible to use it as a plow working machine with a subsoil attached.

A third embodiment is shown in FIG. A small earthenware 70 with a small soil repellent plate is attached to the land side 18 via a bracket 72 and acts to raise the earthen below the bed 25 and release it into the gravel groove. The same result as in FIG. 18 can be obtained.

The excavated subsoil when forming the groove 60 has different gravel stripes depending on the shape of the soil repellent plate 37. For example, as shown in FIG. 18 and FIG. 19, when turning leftward as viewed from the rear, it accumulates on the left side of the groove 60 like a gravel 61 of subsoil. That is, the gravel strip 61 of the subsoil can be formed at any position of the gravel groove 63 by changing the soil repellent angle of the subsoil 30 with the soil repellent plate.

In these plowing, if you work over several years while slightly shifting the position of the earthenware 30 and 30a with earth repellent plate, a lot of grooves 60 will be made in the subsoil layer, and soil is created in the grooves 60 As it is mixed, the soil layer becomes thick and the rhizosphere area expands.
In addition, after every year the subsoil rises into the soil layer and is freed and matured, then the next plowing will rise to the surface for the first time. be able to. When the position of the subsoil with the soil repellent plate makes a round of the whole field, the soil is mixed up to the deep position of the tip of the subsoil 30, 30a, and the subsoil layer is physically improved, so the crop root Will grow deeper, will not fall over and will not be ill easily, and will be able to expect higher sales.
In order to shift the position of the subsoil 30 and 30a little by little, the length of the bracket 22 is changed and replaced for each plowing, or the plowing start position is marked on the field. You can work by shifting. Furthermore, after plowing in the vertical direction, the soil layer can be reliably improved by plowing in the horizontal direction.

In the present invention, field crops are mainly studied, but it can be used in places such as paddy fields where it is desired to expand the soil layer.
