Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a rowing machine used for ridge creation, restoration work and the like.

[Conventional technology]

Conventionally, Japanese Unexamined Patent Publication No.
As disclosed in Japanese Utility Model Application Laid-Open No. 61-158105 and Japanese Patent Application Laid-Open No. 62-190002, a traveling machine is provided with a machine frame, and the machine frame is provided with a rotating rotor for laying up soil on an old ridge. It is known that a ridge body that can be tightened by vibration with a vibration generator at a position is provided.

[Problems to be solved by the invention]

However, in the case of the above-mentioned conventional structure, the ridge body is formed in a vertical cross section in accordance with the ridge upper surface and the ridge one side surface by the upper plate portion and the side plate portion. There is an inconvenience that the soil falls on the outer surface of the ridge and the embankment amount on the ridge decreases accordingly, thereby lowering the embankment efficiency and failing to obtain a good ridge.

[Means for solving the problem]

The purpose of the present invention is to solve these inconveniences. The gist of the present invention is to provide a machine frame on a traveling body, provide a rotating rotor on the old ridge on the machine frame, and advance the rotating rotor. A ridge body having a shape conforming to the upper surface of the ridge and one side surface of the ridge is provided at a position rearward in the direction, and a vibration mechanism for oscillating the ridge in the ridge is provided. And a rear tightening surface, and a window hole is formed at a boundary between the two.

[Action]

As the ridges progress, the embankment from the rotating rotor is first fastened on the front fastening face, and the embankment fastened on this front fastening face and the embankment passing through the window hole are fastened on the rear fastening face.

〔Example〕

1 to 6 show an embodiment of the present invention. FIGS. 1 to 5 show a first embodiment, and FIG. 6 shows a second embodiment.

In the first embodiment shown in FIGS. 1 to 5, reference numeral 1 denotes a traveling body, in this case, a tractor. A tractor 3 is connected to a rear part of the traveling body 1 by a connecting mechanism 2, and the tractor 3 is mounted on an old ridge 4. Is provided with a rotating rotor 5 which crushes and swells the soil at the ridge.

In this case, the rotating rotor 5 is formed by projecting a plurality of claw-shaped rotor blades 5b on the outer peripheral surface of the rotor body 5a, and the power shaft 8 of the traveling body 1 is connected to the power shaft 8 through the universal joint 7 by the power take-out shaft 6. Rotates, and a gear mechanism 10 is interposed between the power shaft 8 and the intermediate shaft 9,
And a chain mechanism between the intermediate shaft 9 and the rotary rotor 5.
The rotary rotor 5 is configured to rotate with the intermediary of the rotary rotor 11.

Reference numeral 12 denotes a cover member. The cover member 12 is provided on the machine frame 3 above the rotary rotor 5 and above the ridge, and a rubber rear cover 13 is provided on the rear side of the cover member 12 in the traveling direction.
Is suspended vertically.

Reference numeral 14 denotes a vibration mechanism. In this case, two links 15 are pivotally supported on the machine frame 3 by a pull-up spring 16, an attachment 17 is provided at the tip of the link 15, and a support frame 19 is provided on the attachment 17 by a spring 18. , The ridge body 20 is attached to the support frame 19, and two eccentric boards 21 are rotatably mounted in the support frame 19, and the power shaft 8 and the transmission mechanism are mounted.
A chain mechanism 24 is interposed between the input shaft 23 and the input shaft 23, the output shaft 25 of the transmission mechanism 22 and the eccentric disk 21 are connected by a flexible shaft 26, and the two eccentric disks 21 can be transmitted by the belt 27. And the ridge tightening operation is performed by the vibration caused by the rotation of the eccentric disk 21.

Reference numeral 28 denotes a pulling mechanism, and a U-shaped leaf spring is
Fix one end of 29 and bolt 30 to the other end of leaf spring 29
One end of the wire 32 is connected by a nut 31 and the other end of the wire 32 is connected to a connecting piece 33 attached to the support frame 19, and the support frame 19 is elastically supported by a leaf spring 29 so as to be movable in the traveling direction. At the same time, the forward limit of the vibrating ridge body 20 is regulated by the contact between the rear part 17a of the attachment body and the leaf spring 29,
The levee body 20 can be disposed close to the rotating rotor 5 by avoiding collision between the rotating ridge 5 and the rotating ridge 5.

This ridge body 20 is formed in a vertical cross section in conformity with the ridge upper surface and the ridge one side surface. In this case, the front upper plate portion 34 and the front side plate portion 35 are formed in a vertical cross sectional shape, and Upper plate
36 and the rear side plate portion 37 are formed in a longitudinal cross-sectional shape, and a window hole 40 is provided between the front tightening surface 38 and the rear tightening surface 39 formed by this, and is reinforced by a rib 41 and integrally formed. And the front tightening surface 38 is
It is set at a position one distance away from 39, and furthermore, a rear rising part 42 is formed on the rear side of the window hole 40, and a front rising part 43 is formed on the front side of the ridge 20. An upper edge plate portion 44 and a lower edge plate portion 45 are formed between the upper edge portion 42 and the upper portion 42.

Further, in this case, the front side of the ridge 20 is located inside the rear cover 13 and is arranged as close to the rotating rotor 5 as possible.
The rear standing upper portion 42 is located close to the rear cover 13.

Reference numeral 46 denotes wheels that can move up and down, and supports the machine frame 3.

47 is a shock absorber, 48 is a vertical foot plate member, and 49 is a stopper material.

Since the first embodiment has the above configuration, the traveling body 1 travels along the old ridge 4 and the power take-off shaft 6 is rotated. On the other hand, the rotating rotor 5 continuously crushes the field soil on the old ridge 4. And the cover member 12 and the rear cover 13 prevent the mud from being scattered above the rotating rotor 5 and to the side of the ridges. The ridges are tightened in the shape of the ridge 20 in a state of being sandwiched, and ridge work is performed.

At this time, since the window 40 is formed at the boundary between the ridge-clamping surface 38 and the rear-clamping surface 39 of the ridge 20, the embankment by the rotating rotor 5 is first moved forward as the ridge 20 is advanced. The embankment tightened by the tightening surface 38 and the embankment tightened by the front tightening surface 38 and the embankment passing through the window hole 40 are tightened by the rear tightening surface 38. 5 can be placed close to the ridges, and the ridges can be tightened well, so that the water leakage of the surface water can be prevented well, and excellent ridges can be obtained.

In the second embodiment shown in FIG. 6, each R-shaped body 20 of the first embodiment is approximated to the basic shape with the R shape as a corner.

It should be noted that the present invention can be applied to a case in which a hydraulic mechanism or the like is employed as the vibration mechanism 14 in the above embodiment, and also to a case in which a plurality of ridges 20 are arranged.

〔The invention's effect〕

As described above, since the present invention is formed by dividing the ridge tightening surface of the ridge body into a front tightening surface and a rear tightening surface and forming a window hole at the boundary, the embankment by the rotating rotor as the ridge body progresses. First, the embankment is tightened with the front tightening surface, and the embankment that has been tightened with this front tightening surface and the embankment that has passed through the window hole are tightened with the rear tightening surface. As a result, the ridge tightening becomes good, and the water leakage of the surface water can be satisfactorily prevented, and an excellent ridge can be obtained.

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