Publication No. 44-16668 and the like are known.

In these structures, the machine frame is connected to the rear of the tractor by a coupling mechanism, the machine frame is provided with an earth embankment rotor or a disc-shaped blade plate, and the tractor is run along the old ridge, and the earth embankment rotor or Scrape off one side of the old ridge with a disc-shaped blade plate and heave the excavated soil above the ridge, or send the excavated soil to the scraped surface with a cultivation plate and mound the mud on the ridge along the front edge in the direction of travel. It is constructed so that it can be tapped with the trailing edge of a screwed ridge-beating board, or rubbed with a fixed application board.

[Problems to be solved by the invention] However, in the case of these conventional structures, the scraped surface that becomes the ridge side is struck with the trailing edge of the ridge pounding plate in the advancing direction, or the mud sent by the soil plate is fixedly applied. Because it is only stroked with a board, the tightening of the ridges, especially the ridge sides, is weak and it may not be possible to obtain strong ridges, and neither of these methods can carve out the inside of the old ridges.
Because it simply piles mud from the foot of the old ridge or from the field onto the old ridge, it is not possible to reliably fill in cavities such as crayfish holes that exist inside the old ridge, and it is not possible to reliably fill in cavities such as crayfish holes that exist inside the old ridge. The adhesion of mud between the external mud of the old ridge and the embankment was low, and therefore it was difficult to integrate the old ridge and the embankment, resulting in a weak ridge that was more likely to collapse.

[Means for solving the problem] The purpose of the present invention is to solve these inconveniences, and its gist is to connect a machine frame to a tractor by a coupling mechanism, and to plow the inside of the old furrow to the machine frame. A rotating rotor is provided, which has a plurality of raking blades for raising soil, and is rotated by the power of a tractor to throw up soil onto the old ridge. A ridge beating body with a vertical cross-sectional shape that matches the top surface of the ridge and one side of the ridge is provided at a rear position in the direction of movement of the rotor, and the entire ridge beating body is used to beat the ridge in the direction toward the top surface of the ridge and one side of the ridge. a furrow beating mechanism that is movable and that uses the power of the tractor as a drive source to cause the furrow beating body to perform reciprocating furrow beating operation;
A plurality of raking blades of the rotating rotor capable of performing a plowing action are arranged to protrude toward the ridge side from a ridge beating completion position of the ridge beating body and to plow the inside of the old ridge. There is a ridge adjustment machine that does this.

[Function] When the tractor travels along the old ridge, the rotating rotor is rotated by the power of the tractor, and its plurality of raking blades throw up soil onto the old ridge and embank it, and the raking blades of the rotating rotor, which are capable of plowing, The upper blade enters the inside of the old ridge in a direction that intersects with the ridge creation direction, plows the inside of the old ridge, and the ridge pounding mechanism is driven by the power of the tractor to create a longitudinal section that matches the top surface of the ridge and one side of the ridge. The surface-shaped ridge beating body as a whole reciprocates in the direction toward the upper surface of the ridge and one side of the ridge, and at this time, the rotary rotor disposed in the direction where the axis of rotation intersects the ridge creation direction can perform the plowing action. The plurality of raking blades are positioned protruding to the ridge side from the ridge beating completion position of the ridge beating body and plow the inside of the old ridge, so the ridge beating body plows the ridges plowed by the raking blades of the rotating rotor. Pound the soil.

[Embodiment] FIGS. 1 to 4 show an optimal embodiment of a ridge straightening machine to which the present invention is applied, in which 1 is a tractor, and a machine frame 3 is connected to the tractor 1 by a coupling mechanism 2. It is connected so that it can be raised and lowered.

The coupling mechanism 2 is composed of a hydraulic arm 4, an upper link 5, a lifting link 6, and a lower link 7.

Reference numeral 8 denotes a main shaft, which is rotatably installed horizontally on the machine frame 3 and rotated by the power take-off shaft of the tractor 1 via a universal joint 9.

10 is a rotating rotor, the rotating rotor 10 is composed of a rotor body 11 and a scraping blade 12, the rotational axis R of the rotating rotor 10 is provided protruding from the machine frame 3 in a direction intersecting the direction of creating the ridge 13, and It is rotated by the main shaft 8 via gears 14 and 15.

A cover member 16 is provided on the machine frame 3 above the rotating rotor 10 and above the ridge 13.

Reference numeral 17 denotes a ridge beating body, which includes an upper plate member 17a that strikes the upper surface of the ridge 13 and a side plate member 17 that strikes one side of the ridge 13.
Vertical section that matches the top surface of the ridge and one side of the ridge due to b
It is formed in a shape and is provided at a rear position in the direction of movement of the rotating rotor 10, and has two swing links 18 pivotally mounted and protruding from the rear of the machine frame 3, and the tips of the swing links 18 are mounted in the mounting arm 19. A ridge tapping body 17 is provided in the middle of the mounting arm 19, and the entire ridge tapping body 17 can be reciprocated in the direction toward the top surface of the ridge and one side of the ridge.

Reference numeral 20 denotes a ridge beating mechanism, in which a crank body 21 is provided at the rear of the machine frame 3, the crank body 21 is rotated by a main shaft 8, and the crank body 21 and the upper part of the mounting arm 19 are pivotally connected by a push link 22. It is configured as follows.

Moreover, the ridge beating body 17 performs a reciprocating tapping operation, but the ridge beating body 17
The plurality of raking blades 12 capable of plowing of the rotating rotor 10 are positioned to protrude toward the ridge side from the ridge beating completion position a of No. 7, that is, the protrusion limit position of the ridge beating body 17, and plow the inside of the old ridge. It is configured as follows.

Since this embodiment has the above configuration, the tractor 1
When traveling along the ridge 13, the plurality of scraping blades 12 of the rotating rotor 10 are moved along the ridge 1 by the power of the tractor 1.
3.Not only does it scrape off the muddy soil at the foot of the field and in the field, but it also bounces up and fills it up. It rotates into the inside of the old ridge and plows the inside of the old ridge, crushing the hard soil inside the old ridge, and digging out mouse holes and crawfish holes. Breaking and flipping up, rotating rotor 10
A plurality of raking blades 12 capable of plowing are used as a ridge beating body 17.
Since the inside of the old ridge is being tilled at a position that protrudes beyond the ridge beating completion position a, the ridge pounding body 17 must be used to plow the tilled soil b.
It can be tightened tightly even inside the old ridge, and it can also break down rat holes and crawfish holes.It also improves the adhesion between the old ridge soil and the embankment, making it easier to integrate and create strong ridges that will not collapse easily. The ridge beating body 17 is formed in a vertical cross-sectional shape that matches the upper surface of the ridge 13 and one side of the ridge, and the entire ridge beating body 17 is capable of beating the ridge in the direction toward the upper surface of the ridge 13 and one side of the ridge. Since the ridge beating mechanism 20 is driven by the power of the tractor 1, the entire ridge beating body 17 moves in a reciprocating manner toward the top surface of the ridge and one side of the ridge, thereby improving the ridge. The upper surface and one side of the ridge are simultaneously pounded and tightened, and the old ridge and the ground are sandwiched and tightened, including the tilled soil b, between the ridge pounding body 17, and as a result, a strong and robust ridge can be obtained. In particular, since the rotation axis R of the rotor 10 is configured to intersect with the ridge creation direction, the rotation axis R of the rotation rotor 10 is more For example, the support structure of the machine frame 3 can be made into a cantilever support structure, which is a commonly adopted structure, which simplifies the support structure, and reduces the space for the rotary rotor 10 in the ridge-creating direction. Not only can it be made more compact, but the amount of protrusion of the rear part of the machine frame 3 from the tractor 1 can also be reduced, reducing the load on the coupling mechanism 2 and suppressing the vibration of the machine frame 3. is the rotating rotor 10
The rotation transmission mechanism of the rotor 10 can also be simplified, and the entire machine can be simplified and made more compact.Also, since the rotation axis R intersects with the ridge creation direction, the rotation axis R of the rotating rotor 10 can be connected to the ridge 13. If the tilling direction of the rotor 10 is arranged parallel to the direction of construction, the tip of the tilling rotor 10 will have an arc shape when viewed from the cross section of the ridge 13. Therefore, the tip of the rotor 10 at the top of the ridge and at the base The locus also becomes an arc shape, and there may be parts that are not tilled inside the old furrow 13, resulting in insufficient tillage.In addition, the amount of soil heaped up, that is, the amount of soil removed, may be insufficient, and the tillage may be insufficient. In order to deepen the tillage to the inside of the old furrow 13, it is necessary to increase the outer diameter of the tilling locus of the rotating rotor 10, which results in an increase in the size of the rotating rotor 10.
Although the entire device becomes larger and particularly taller, if the rotation axis R of the rotating rotor 10 is arranged in a direction that intersects the ridge creation direction, the tilling tip trajectory of the rotating rotor 10 will be approximately L-shaped when viewed from the ridge cross section. Therefore, the rotating rotor 10 can be positioned protruding into the old ridge 13 without increasing the outer diameter of the tip of the cutting edge of the rotating rotor 10, and the inside of the old ridge 13 can be sufficiently cultivated, and the amount of soil to be removed and piled up can be increased. Therefore, the height of the entire operation can be reduced without increasing the amount of rear protrusion of the machine frame 3, and as a result, plowing and heaving can be performed in good condition, and the entire device can be simplified and made more compact. Therefore, it is possible to obtain a better tilling and heaping effect than in the case where the axis of rotation R is arranged parallel to the direction of ridge construction, and thereby a good and robust ridge can be obtained.

[Effects of the invention] As described above, in the present invention, when a tractor is driven along a ridge, the power of the tractor causes the plurality of raking blades of the rotating rotor to scrape off the foot of the ridge and the field mud and flip it up to fill the soil. Not only that, but also by rotary drilling into the inside of the old ridge, plowing the inside of the old ridge, breaking up the hard soil inside the old ridge,
The plurality of raking blades capable of plowing by the rotating rotor are positioned so as to protrude from the ridge beating completion position of the ridge beating body to plow up the inside of the old ridge. The above-mentioned tilled soil is always pounded and compacted by the ridge pounder, and even the inside of the old ridge can be compacted.
It can also destroy mouse holes and crawfish holes, and by improving the adhesion between the old ridge soil and embankment, it is easy to integrate with the embankment, creating a strong ridge that does not collapse easily. It is formed in a vertical cross-sectional shape that matches the side surface, and the entire ridge beating body is provided so that it can be moved in the direction toward the top surface of the ridge and one side of the ridge, so that the ridge beating mechanism is driven by the power of the tractor. The ridge-beating mechanism causes the entire ridge-beating body to perform a reciprocating ridge-beating operation toward the top surface of the ridge and one side of the ridge, and simultaneously slams the top surface of the ridge and one side of the ridge as a whole, thereby pounding the old ridge and the ground. The plowed soil is sandwiched between the body and the plowed soil, and as a result, a strong and sturdy ridge can be obtained. Compared to the case where the rotor is arranged so that its axis of rotation is parallel to the ridge construction direction, the support structure of the rotating rotor can be made into a commonly used cantilever support structure, which simplifies the support structure. Not only can the space for the rotating rotor in the ridge building direction be reduced, making the machine frame more compact, but also the amount of protrusion of the rear part of the machine frame from the tractor can be reduced. This reduces the load on the coupling mechanism and suppresses the vibration of the machine frame, and also simplifies the rotation transmission mechanism of the rotating rotor, making the entire machine simpler and more compact. If the axis of rotation of the rotating rotor is arranged parallel to the direction of ridge creation, the tilling tip trajectory of the rotating rotor will be arc-shaped when viewed from the cross-section of the ridge. The trajectory of the tip of the rotating rotor on the top surface of the ridge and at the bottom of the ridge also becomes an arc, which may result in uncultivated areas within the old ridge, resulting in insufficient tillage, and the amount of soil heaped up or removed may be reduced. However, if you try to deepen tillage into the inside of the old furrow, you have to increase the outer diameter of the tilling locus of the rotor, which increases the size of the rotor and the entire device. Although the height is particularly high, if the axis of rotation of the rotating rotor is arranged in a direction that intersects the direction of ridge creation, the tilling tip trajectory of the rotating rotor will be approximately L when viewed from the ridge cross section.
As a result, the rotating rotor can be positioned protruding into the old ridge without increasing the outer diameter of the cutting edge of the rotating rotor, and the inside of the old ridge can be sufficiently cultivated, and the amount of soil scraped and piled up can be increased. The height of the entire operation can be reduced without increasing the amount of rear protrusion of the frame, and as a result, plowing and heaving can be performed in good condition, and the entire device can be simplified and compact, and the rotation axis It is possible to obtain a better tilling and heaping effect than when the R is arranged parallel to the ridge creation direction, and thereby a good and robust ridge can be obtained.

As described above, the intended purpose can be fully achieved.
