Description

[Detailed description of the invention] [Industrial application field]

The present invention involves blowing compressed air vigorously into the deep layer of the soil, causing cracks in the cultivated soil from the deep layer to the surface layer by this jet stream, and roughly cultivating the soil. This invention relates to a self-propelled deep tillage/intertilage device that performs fine plowing and intertilling in one stroke so that seeds can be sown and seedlings can be transplanted.

[Conventional technology]

As a device similar to this type of self-propelled deep plowing/intermediate plowing R device, a rotary tilling device is installed at the rear of the tractor, and a subsoil crushing blade II is located at the center of the rear of this rotary tilling device. An exhaust port is provided at the rear of the lower end of the crushing blade, and a communication port is provided at the upper end of the blade that communicates with the exhaust port, compressed air is supplied from a compressor to this communication port, and the rotary After the soil from the middle layer to the surface layer is tilled by the tilling device, the 11 deep layers are deeply plowed with a subsoil crushing blade, and the deep plowing is further promoted by the jet stream of compressed air. , Japanese Patent Publication No. 1983-
This is proposed by Japanese Patent No. 78501.

[Problems to be solved by the invention]

The above farming! ! In this machine, as shown in Figure 3 of the publication, the deep layer of the cultivated soil, which has been thinned from the middle layer to the surface layer over the entire surface of the field by the rotary tilling device, is crushed into subsoil by the subsoil crushing blade. At the same time as crushing, compressed air is ejected and the compressed air is used for deep plowing, so the narrow pt area with the rotary tiller extends deep to the middle layer of the tilled soil, and the entire field is covered in small rivers. Fields that are easily washed away by rain or blown away by wind tend to become deserts in fields that are easily washed away by rivers, and crops that are sown or transplanted in such fields are more likely to be washed away by the rain or blown away by the wind. Because of their roots, they tend to be easily blown down by the wind or washed away by the rain. In addition, conventional tillage using rotary tillers and top-to-bottom turning using overhead tillage have the effect of softening high-moisture soil, but ■ they bring organic humus to the surface and inhibit the promotion of humus. ■ Inhibits microbial activity. ■ Destroy the soil structure (soil layers) by using mixed layers with tillers, shovels, etc. There were also other problems.

[Means to solve the problem]

In view of the above-mentioned circumstances, the present invention aims to blow compressed air from an air blower installed at the lower end of a blower support that is attached to a self-propelled vehicle such as a tractor and towed through the soil to spread the soil from the deep layer to the surface layer. By using inter-tillage equipment to leave a coarse-grained area in the surface layer of the cultivated soil, and by diluting it into a thin stream for sowing or transplanting seedlings, it is possible to sow seeds or transplant seedlings as is. The roots of the cultivated crops grow well from the area finely cultivated with the inter-tillage equipment to the coarse soil area below, and the roots of the crops are firmly planted in the cultivated land. As well as promoting li!

Next, the operation of the above embodiment will be explained. The deep plow/medium 11 loader M5 is attached to one branch of the tractor 1 via a three-point link hitch mechanism 4, and transmits rotational power from the PTO shaft 1a of the tractor to the input shaft 10a of the gear box 100 via the power transmission system 13. , drives the compressor 11 and the intercultivation device 24. Then, when proceeding, the fumarole column 1
7 and air fumes 18 are forced into the deep layer of the cultivated soil from the ground, and the group of inter-tilling claws 29 rotates in the surface layer of the cultivated soil and is pulled by the tractor 1. Then, the fumarole column 17 cuts the T-tumulus to the left and right, and the air fumarole 18 moves horizontally through the deep part of the cultivated soil.
, the surface layer of the cultivated soil behind the fumarole column 11 is tilled. During this process, the solenoid valve 21 is opened at a predetermined timing by operating the switch in the switch box 21a, and when the solenoid valve 21 is opened, the compressed air stored in the sub-tank 22 is released.
The air is vigorously ejected upward from the blowhole 20 through the air supply pipe 19. As shown in Fig. 1, this ejection of high-pressure air causes cracks (crack I'I area C) from the deep layer of the cultivated soil above the fumarole hole 20 to the surface layer, and as the fumarole progresses, the fume of compressed air By sequentially performing these steps at predetermined timing intervals, crack areas C are continuously formed and the tilled soil is coarsened. Then, the surface layer of the cultivated soil coarsened by the deep tillage device is finely divided into medium v1 by inter-tillage [24] so that the coarse-grained v4 area can be left behind for sowing and transplanting of seedlings. In addition, since the deep tillage device is placed in front of the inter-tillage device, the jet flow that formed the crack area C does not blow up the ll111 soil in the surface layer, and the inter-tillage device 24 can remove the surface layer of the cultivated soil that has cracks to some extent. Since the soil is intercultivated, the required power is less, and furthermore,
The traces of the fumarole column 17 are leveled and disappear at the same time as the intercultivation work. Then, as shown in FIG. 3, WI! 4 or when the seedlings are transplanted, the roots R of the crop B will initially grow in the thin part A, and then
The cultivated soil stretches from the coarse phase part A to the hard coarse phase part C, and is firmly attached to the cultivated soil, which prevents the soil from being blown down by the wind or washed away by the rain.The growth of crop B is promoted, and it is also good for grass leaves on the ground. results and can promote increased yields of above-ground or below-ground crops. In particular, for long-rooted crops such as radish, radish, carrot, and yam, the roots grow well and grow straight and long, making it possible to produce high-quality products. It may be arranged on the front side of the fumarole strut 17, and the fumarole strut 17 and the intercultivation device 24
The number of seedlings may be increased or decreased as appropriate.Furthermore, a sowing device or a transfer Ifl device is attached to this deep tillage/intertilling device to simultaneously sow seeds or transplant seedlings to the area that has been intercultivated with the intercultivation device W124. It may be done as follows. [Effect of the invention] As is clear from the above explanation, the self-propelled deep plowing machine of the present invention
According to the inter-cultivation device, a self-propelled vehicle is equipped with the inter-cultivation device, which is located on either side of the front or rear of the deep-cultivation device and the fumarole column in the deep-cultivation device, and is located on the movement line -1- along which the fumarole column moves. The depth V1 device coarsens the cultivated soil from the deep layer to the surface layer, and the intermediate tillage device finely uses the surface layer of the cultivated soil, leaving an area coarsely tilled by the depth V1 device, so that the fine and coarse portions are Sowing or transplanting of seedlings can be carried out immediately. Then, the roots that develop in the coarse parts,
In the rough plowing part below, it is firmly stretched to 11 people,
The crops will not be blown down or blown away by the wind, nor will they be washed away by the rain, allowing for good growth and increased crop yields. In addition, since the inter-tillage device finely uses the surface layer of the tilled soil, leaving the area coarsened by the deep-tillage device, it is similar to the conventional rotary tillage device that plows the entire field from the intermediate Ii1 section to the surface layer. In addition, it prevents agricultural fields from turning into deserts, where cultivated soil is washed away by the rain or blown away by the wind, and is thus effective for crops as well. In addition, as a measure to prevent topsoil erosion and desertification, growing grass over the entire surface of the field, so-called weeding, has been effective, but even in this case, the device of the present invention can be used in detail from the topsoil to the deep soil. At the same time, since the surface soil of the sowing area and seedling planting area can be divided into fine rows using inter-tillage equipment, the vegetation effect can be effectively utilized, which is even better in preventing topsoil erosion and desertification. be effective. Furthermore, since it is possible to sow seeds or transplant seedlings at a medium depth at the same time as deep plowing, labor-saving and highly efficient work can be performed.
