[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a ridge treatment device which is used by being attached to a rotary provided at the rear of an agricultural tractor and which advances the tractor along the ridge to scrape the soil on the ridge.

[0002]

[Prior art]

 As this type of ridge processing device, as shown in FIG. 4, a support frame 11 attached to a side portion of a rotary, a rotary plowing disk 12 provided upright with respect to a soil layer surface, The plowing disk 12 includes a shaping plate 13 that forms a groove on the surface of the soil layer cut by the plowing disk 12.

The support frame 11 is composed of a connecting portion 11a attached to the rotary side portion, and a supporting rod 11b protruding downward from a rear end portion of the connecting portion 11a. The plowing disk 12 is provided at the lower end of the supporting rod 11b such that the front half of the standing state is located outside the center of rotation with respect to the rear half. The shaping plate 13 has its front end fixed to the rotary shaft of the plowing disk 12, and its rear end located inside the front end. Further, the shaping plate 13 is gradually widened from the front end portion to the rear end portion, and is inclined obliquely upward from the inner side to the outer side.

In this ridge treatment device, when the support frame 11 is fixed to a side portion of a rotary and towed by a tractor, the plowing disk 12 cuts the soil on the surface of the soil layer by its rotating operation, and the inside rearward. Then, the shaping plate 13 further pushes the soil on the surface of the soil layer inward and rearward along the inclination of the shaping plate 13 to form a groove M extending in the traveling direction of the tractor as shown in FIG.

[0005]

[Problems to be Solved by the Invention] By the way, in recent years, concrete ridges are often provided in order to maintain accurate divisions in cultivated land. However, when the above-mentioned ridge bank treatment device is used for such a concrete ridge C, even if the plowing disk 12 is brought close to the ridge and the groove M is formed, as shown in FIG. The soil at the bottom of the soil cannot be completely scraped out, and there is a portion of soil that is left unscraped called residual tillage. For this reason, when weeds and the like grow on this residual tillage Z, the worker has to remove them manually, which is troublesome and troublesome, and there is a problem in that the work efficiency in agricultural work is reduced.

Therefore, an object of the present invention is to provide a ridge processing device that does not leave residual tillage even when used on a concrete ridge, and to reduce extra labor required for agricultural work.

[0007]

[Means for Solving the Problems]

 In order to solve these problems, in the present invention, a support frame attached to the side of the rotary provided at the rear of the tractor and a lower end of the support frame are raised from above the soil layer surface. In the state, the ridge treatment device comprising a rotary plowing disc that is inserted in a slanting direction with respect to the traveling direction and a shaping plate that forms a groove on the soil layer surface at the rear position of this plowing disc, At the rear position of the plowing disc, we decided to install a residual tillage treatment device that scrapes the residual plowing that occurs at the bottom of the plowing disc.

Even when used on a concrete ridge, such a ridge treatment device can be used in a concrete ridge because the residual tiller scrapes the soil below the plowing disc behind the plowing disc. There is no remaining plow.

The residual tillage treatment device may be configured by a residual tillage scraping plate that hangs up to the lower end position of the tillage disk in a state of standing upright on the soil layer surface and that is inclined with respect to the traveling direction of the tractor. As a result, as the tractor advances, the soil at the bottom of the tilling disc scratched by the residual tillage scraping plate is transferred rearward along the inclined surface thereof, so that the residual tillage can be reliably treated.

Further, this residual tillage scraping plate is detachably attached to the support frame and is provided at the rear end portion of the arm extending to the rear of the tilling disc, so that it is used for soil ridges. When there is no particular need, such as the case, the residual tiller can be removed.

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the accompanying drawings. The ridge processing device A shown in FIG. 1 includes a support frame 1 attached to a rotary R of a tractor T, a rotary plowing disk 2, and a shaping plate 3 that forms a groove on the surface of the soil layer. At the rear position of the support frame 1, a residual tiller 4 is attached.

The support frame 1 is composed of a connecting portion 1a formed of a square pipe extending rearward from a side portion of the rotary R and a supporting rod 1b which is welded to a rear end of the connecting portion 1a and projects downward. There is. The connecting portion 1a is formed with a plurality of bolt holes communicating with the upper and lower surfaces thereof in the longitudinal direction, and is slidably fitted into a connecting pipe 5 provided on the side portion of the rotary R and having front and rear openings. Has been. The support frame 1 is fixed to the side portion of the rotary R by bolting the connecting portion 1a and the connecting pipe 5, and the length can be adjusted by changing the position of the bolt hole. It has become.

The plowing disk 2 is axially supported at the lower end of the supporting rod 1b in a state of standing upright on the surface of the soil layer. The front half of the plowing disk 2 is located outside of the rear half with respect to the center of rotation, and as a result, in plan view, the plowing disk 2 is inclined slightly outward with respect to the traveling direction of the tractor T. ing.

The shaping plate 3 is formed such that its rear end is wider than the front end fixed to the shaft supporting portion of the tillage disk 2, and the reinforcing rods 6 are provided at both front and rear ends thereof. ing . The shaping plate 3 is inclined obliquely upward from the inner side toward the outer side, whereby the soil cut by the plowing disc 2 is pushed inward as the tractor T advances, and the traveling direction of the tractor T increases. Form a groove that extends to.

The residual tillage treatment device 4 connects the residual tillage scraping plate 7 standing upright to the surface of the soil layer, the residual tillage scraping plate 7 and the support frame 1, and extends to the rear of the tilling disk 2. It is composed of an arm 8. The residual tillage scraping plate 7 is made of a steel plate formed by bending a parallel plate portion 7a parallel to the traveling direction of the tractor T and an inclined plate portion 7b extending obliquely rearward from the front end of the parallel plate portion 7a. 2 to the lower end position and welded to the rear end of the arm 8. The arm 8 has an attachment piece 8a for the support frame 1 at the front end thereof, and is attachable to and detachable from the support frame 1 by bolting the attachment piece 8a to the support rod 1b of the support frame 1. Has become.

In such a ridge processing device A, when the support frame 1 is fixed to the side of the rotary R and the plowing disk 2 is pulled by the tractor T along the concrete ridge C, the plowing disk 2 is removed. By the rotation operation, the soil on the surface of the soil layer is cut and transferred to the inside rear, and the shaping plate 3 further pushes the crushed soil along the inclination to the inside rear to form a groove.

At this time, a soil scraping part is formed in the lower part of the plowing disk 2, but as shown in FIGS. 2 and 3, the residual plowing scraping plate 7 is formed behind the plowing disk 2. Further scrapes the soil behind the plowing disk 2 to the lower end position and transfers this soil to the rear inside along the inclined plate portion 7b, so that no residual plowing remains in the groove.

Further, since the arm 8 of the residual tillage treatment tool can be attached to and detached from the support frame 1, the residual tillage treatment tool can be removed when it is not particularly required such as when using it on a soil ridge. You can drop it.

[0019]

【effect】

 As explained above, the levee treatment device according to the present invention is used in the rear azimuth direction of the plowing disc, since the residual tiller removes the soil left by the plowing disc. Does not leave any tillage. Therefore, extra work such as weeding work on the ridge is reduced, which contributes to improvement of workability in agricultural work.

Further, since the residual tiller can be attached to and detached from the support frame, it can be removed when it is used for soil ridges, etc., and it does not interfere except when necessary.
