Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural tractor for plowing agricultural soil, which relates to an agricultural tractor used for plowing the ridges.

[0002]

2. Description of the Related Art An agricultural tractor (see FIG. 4) has a rotary shaft 10 installed laterally on bearing brackets 13 at both left and right ends.
In addition, the rotary plow blade 11 having a large number of rotary plow blades 11 arranged in parallel at a fine pitch is provided at the rear portion of the vehicle body to cultivate the cultivated soil by the rotary plow blade 11 that is rotated by the traveling of the tractor. However, the bearing portion 12 of the support bracket 13 that supports the rotary shaft 10 is
There is a slight distance from the rightmost end (or the leftmost end) of the rotary plow blade 11A to the tip of the bearing portion 12.

When the cultivated soil is cultivated along the concrete ridges 15 and the soil ridges 16 by the above-mentioned agricultural tractor, the ridges 15.1.
Since the rotary plow blade 11A at the end cannot run along the edge of 6 "perfectly" (because the bearing 12 contacts the cultivated soil, the distance from the ridges 15 and 16 is required). Untilled surplus soil 1 that cannot be tilled along 15/16
It is unavoidable that 7 continuously remains, and a work method of cultivating the unplowed residual soil 17 by a secondary manual work is adopted.

On the other hand, as a structure for relaxing the secondary work of the manual work, there is a known example shown in Japanese Patent Laid-Open No. 62-171602, in which an auxiliary shaft having a rotary shaft 10 extended to the ridge side has an auxiliary plow. It has a structure with a blade.

[0005]

According to the above-mentioned conventional plowing method by the agricultural tractor, it takes a great deal of time and time for the manual plowing of the unplowed residual soil 17 generated along the ridges 15 and 16. Agricultural work becomes complicated, and JP-A-62-1 is used.
In the known example of Japanese Patent No. 71602, the auxiliary shaft has a ridge 1.
Since it is easy to damage because it comes in contact with 5/16, it is complicated and large in size and expensive, and in addition, the tractor operation is complicated and a large amount of untilted soil 17 remains, so that manual finishing plowing is required. There are various difficulties such as the need to start.

Further, when the ridges are cultivated by the agricultural tractor, the bearing portion 12 is moved close to the ridges 15 and 16 for the purpose of reducing the generation of the un-tilted residual soil 17, so that the bearing portion 12 is ridged. There is a problem that it is inevitable that it will be damaged by contact with 15 and 16. The present invention solves the above-mentioned drawbacks of the prior art, provides a simple and inexpensive structure, is easy to use, and provides a plough-edge plowing plow for an agricultural tractor capable of sufficiently plowing along a ridge.

[0007]

The ridge plowing plow of the present invention which solves the above technical problems is described as follows: "A rotary shaft provided laterally is provided with a rotary plow blade, and bearing parts at the left and right ends of the rotary shaft are provided as a main body. A vertical blade that is supported by a side bracket and is attached to an agricultural tractor plowing by the rotary plow blade that travels forward and is detachably fixed to the bracket in a vertical posture and extends in the traveling direction. It has a plate, and has an upper horizontal blade and a lower horizontal blade that project horizontally toward the rotary plow blade side of the vertical blade plate, and further, the upper horizontal blade is located in front of and below the bearing portion. , The lower horizontal blade is
Located near the lowest point of the radius of gyration of the rotary plow blade, further, the upper horizontal blade and the lower horizontal blade, the cutting soil of the upper horizontal blade and the lower horizontal blade, the cultivated soil sent to the rotary plow blade side. It has a structure that is provided with an inclined plate.

[0008] Then, the above-mentioned ridge plowing plow is attached to the ridge side of the agricultural tractor, and the vertical blade plate is "perfect" for the ridge edge.
Run along, and based on that run, cut the cultivated soil from the ridge in the vertical direction of the required depth by the vertical blade plate, and cut the cultivated soil in the horizontal direction with the upper horizontal blade and the lower horizontal blade. And put it on the horizontal blade, and by the tilling plate located behind the upper and lower horizontal blades,
The cut-off cultivated soil is sent to the rotary plow blade, crushed by the rotary plow blade, and vertically cut along the ridge for plowing.

[0009]

The ridge plowing plough of the agricultural tractor of the present invention having the above-described structure is such that when the vertical blade plate is run along the ridge "perfectly", the vertical blade plate causes the vertical direction from the ridge. The cultivated soil is cut off in the horizontal direction, and the cut cultivated soil is horizontally divided by the upper and lower horizontal blades and placed on each horizontal blade. It is cultivated vertically and beautifully from the edge to the required depth and does not produce conventional untilled residual soil.

During the plowing action, since the upper horizontal blade exists at the position of the above condition, the advancing passage portion of the bearing portion of the rotary shaft is cut and removed by the preceding upper horizontal blade. , The space is secured as a space without cultivated soil, and there is no risk of the bearings coming into contact with the cultivated soil. Furthermore, the cultivated soil cut by the vertical blade plate is horizontally cut by the upper and lower horizontal blades in two stages to the rotary plow blade side. Since it is sent in, a series of cultivating action on the edge of the ridge can be smoothly performed by cutting off the cultivated soil by the plough on the edge of the ridge and sending it to the rotary plow blade.
