Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilling cultivator in which a tilling body mounted on a tilling machine can enter a sufficient depth in the soil in cultivated land during tilling work, and can perform an effective tilling work. Related to the device.

[0002]

2. Description of the Related Art Generally, in order to perform a tilling operation using a small tilling machine, a tilling operation is performed by mounting a tilling body on a drive shaft projecting from both right and left sides of a power transmission case. The tilling body is provided with a plurality of tilling blades around the tilling tube,
In many cases, the cultivation cylinder is formed in a polygonal cylindrical shape such as a triangular or hexagonal cross section. When tilling is performed with a tilling blade, the cultivation cylinder having a polygonal cross-section, while slightly sinking into the soil, rotates to exert a propulsive force at each corner and also makes the soil finer. Meanwhile, tilling is performed with a tilling blade. That is, the tilling blade and the tilling tube rotate while sinking in the soil, and perform an efficient tilling operation.

In some cases, a plurality of tilling bodies are used by connecting a plurality of tilling bodies to a drive shaft projecting from both right and left sides of a power transmission case in an axial direction. Tilling work can be performed by widening the tillage width. Alternatively, there is a till formed by extending the tillage body in the axial direction. In this case, the tillage width can be widened without connecting a plurality of tillage bodies. As described above, by connecting a plurality of tillage bodies or making them long in the axial direction, the tillage work can be performed while widening the tillage width.

[0004]

By the way, as described above, the tillage width can be widened by connecting a plurality of tillage bodies in the axial direction or by using a long tillage body. However, when the tilling body is lengthened in the axial direction, a bending moment acts in the axial direction, and the tilling body that is elongated in the axial direction is bent.

As shown in FIG. 25, the amount of deflection of the tilling body in the axial direction increases as the distance from the power transmission case increases. Therefore, when a plurality of tilling bodies are connected in the axial direction, when tilling work is performed by the cultivator, the tilling cylinder closer to the power transmission case side as shown in FIG. Although it can sink to the required depth in the soil, the tilling cylinder of the outermost tilling body is as shown in FIG.
As shown in (B), the tilling cylinder was lifted off the ground due to the hardness of the soil or the reaction force generated when the tilling blade provided around the tilling cylinder excavated the soil.

For this reason, even if a plurality of tillage bodies are connected in the axial direction in order to increase the tillage width, the outermost tillage is determined only by the tillage blade because the tillage cylinder does not sink into the soil. This is a work, and there is a disadvantage that the effect of the tilling tube does not work at all and the tilling is insufficient.

[0007] Even if the tilling body is long in the axial direction, even if the tilling blade is tilled by the tilling blade at the outermost end opposite to the power transmission case side, the tilling work may not be performed. The force causes the tilling tube to rise from the ground, resulting in a situation similar to that of a plurality of connected tilling tubes.

[0008]

The inventor of the present invention has conducted intensive studies to solve the above-mentioned problems, and as a result, the present invention has been implemented by providing weights on tillage bodies mounted on the left and right sides of a power transmission case of a tiller. By connecting a plurality of tilling bodies in the axial direction on the left and right sides of the power transmission case of the cultivator, symmetrically mounting them, and using a tilling device in a cultivator in which weights are provided on the tilling bodies, By connecting a plurality of tillage bodies, or by using a tillage body that is elongated in the axial direction, the tillage body sinks sufficiently in the soil, and the tillage efficiency can be improved, thus solving the above problem. is there.

Further, the weights 17, 17 of the plurality of tillage bodies A, A,... Connected to the left and right sides of the power transmission case 3 may be provided only on the outermost tillage bodies A, A. Further, the tilling body A is a tilling body Aa for weeding,
It is also possible to perform a weeding operation or a surrogate tilling work as the surrogate tilling body Ab.

The weight 1 is attached to only one of the tillage bodies A, A attached to the left and right sides of the power transmission case 3 of the tiller.
7 can also be provided. As shown in FIG. 19A, the weight 17 is applied to the tilling body A on one of the cultivating bodies A mounted on the left and right sides of the power transmission case 3 (the left side as viewed from the front in the drawing). Is provided. By doing so, the tilling body A on the side where the weight 17 is provided sinks deeply into the soil, and the tilling body A on the side where the weight 17 is not provided sinks shallowly into the soil, as shown in FIG. As shown, the tilling depth can be inclined in the width direction of the tilling.
