６２−７８０２号が知られている。Japanese Utility Model Application Publication No. 186202/1986 by the same applicant is known as a method for performing ridge forming work using a partial deep cultivation device. Also, a! Special Publication No. 1982-7802 is known for carrying out Kasuri and surface crushing work.

む欠点があった。The above-mentioned known technology, Japanese Patent Publication No. 62-7802, as shown in FIG. 11, provides soil crushing claws on the rotating shaft between the ultra-deep UF sections to perform deep plowing and shallow plowing operations at the same time. However, in this coaxial operation, the circumferential speed of the crushed soil in the shallow plowing section becomes significantly slower when the appropriate number of times is applied to the deep plowing section, resulting in rough crushed soil, and if the soil clods in the shallow plowing section are ridged on the ridge surface, they are not suitable for use as a seed bed. There was a case. Furthermore, when soil is placed on the side edge of the mulch film in the partially deep-tiled ridge cross-sectional view shown in Figure 1O, there is a drawback that the soil clods do not allow the film to adhere tightly, creating gaps that allow wind to enter.

る。In order to solve the above-mentioned problems, a tilling device consisting of a deep plowing and crushing section and a shallow plowing and crushing section is provided with means for increasing the rotation speed of the shallow plowing and crushing section compared to the rotation speed of the deep plowing and crushing section. The present invention provides an agricultural tillage device featuring the following features.

合、細粒土が一様に盛土される。According to the tillage device of the present invention, the circumferential speed of the soil crushing claws in the deep plowing excavation section and the circumferential speed of the soil crushing claws in the shallow plowing section are approximately the same, so that the state of crushed soil becomes uniform and finely grained, so that the ridges can be improved. When formed vertically, it is the best condition for germination in the seed bed. Furthermore, when soil is embanked on the side edges of the furrows of the multi-ac 1 film, fine-grained soil is uniformly embanked.

FIG. 1 is a front view showing the first embodiment, with some parts omitted. 1 is a mast frame that supports a transmission box 2, a noon case 3, a side case 4, etc. 1 has a machine frame,
It protrudes from the left and right sides of the transmission box 2 described above, and the transmission shaft passes through the side case 4 side. The IO is fixed to the lower part of the machine frame 11 with a cover to cover the upper part of the crushing claws 5. Reference numeral 6 is a main shaft formed in a cylindrical shape and rotatably supported at the lower part of the nose case 3, and rotational force is transmitted from the above-mentioned transmission box 2 by a chain via sprockets 8 and 8'. 7 is the subshaft and is the machine frame 1 mentioned above.
1 and rotated by a side case 4. The sub-shaft 7 penetrates the inside of the cylindrical main shaft 6 and has a two-component fitting structure. A crushing claw 5 with a large rotational diameter is provided on the outer periphery of the main shaft 6 to constitute a deep plowing excavation section, and a small diameter crushing claw 5 is provided on the left and right sub-shafts of the deep plowing section to constitute a shallow plowing excavation section. However, the sub-shaft of this shallow plowing excavation section is configured to be increased in speed with respect to the main shaft, and the circumferential speeds of the respective crushing claws 5 are set to be approximately the same. Although not shown, if necessary, a ridge forming device or a multi-coating device can be attached to the rear of the cover IO to enable simultaneous multiple operations. Figures 3, 4, 5, 6, and 7 show the second embodiment. A nose case 3 provided at the lower part of the transmission box 2 in FIG. 3 rotates the countershaft 7 by means of a chain via a sprocket 8.8'. The cylindrical main shaft 6 shown in FIG. 6 has an internal gear 14 formed therein, and is supported and rotated by a spur gear 12 provided on the counter shaft 7 and two support gears 13 and 13'. At this time, the speed ratio of the spur gear 12 and the internal gear is approximately 1:2, and the circumferential speeds of the soil crushing claws 5 in the deep excavation section and the soil crushing claws 5 in the shallow cultivation section are set to be approximately the same. FIGS. 8 and 9 show a third embodiment, in which a subshaft 7 is driven from the transmission box 2 through a non case 3, and a cylindrical The transmission gear 17 is driven by appropriately changing the speed of the main shaft 6.

た風が入る等の欠点も解除された。With the above structure, the crushed soil in the deep excavation part and the shallow excavation part is uniformly fine-grained. Therefore, the ridged seed bed in the partially deeply cultivated area is formed of fine-grained soil, which results in uniform germination. Also,
Problems such as wind entering the soil mounds on the side edges of the mulch film, which remain in close contact with each other, have also been resolved.
