Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a ridge trimming machine used for construction and restoration of ridges in rice fields.

[Prior Art] Conventionally, as disclosed in Japanese Utility Model Publication No. 57-10483 as this type of ridge trimming machine, a traveling machine body, embankment rotor, ridge striking body, etc. are provided, and the ridge striking body is used as a crank mechanism. It is configured to reciprocate by, and to embed the mud on the edge of the ridge on the old ridge with the embankment rotor and tap it with the ridge hitting body to consolidate it.

In this case, as the ridge striking structure, there is a so-called lever crank mechanism described above or a hydraulic cylinder mechanism is adopted.In any case, the embankment is struck by the ridge striking body from above or diagonally above. It is configured to tighten.

[Problems to be Solved by the Invention] However, in the case of this conventional structure, since the ridge is tightened by intermittent striking motion, the ridge surface has an uneven shape, and therefore has a surface that is easily collapsed by wind and rain. There is.

[Means for Solving the Problems] An object of the present invention is to eliminate these inconveniences. The gist of the present invention is to connect a machine frame to a traveling machine body and to provide a earth-moving rotor on the machine frame. The machine frame is provided with a ridge striking body having a shape adapted to the upper surface and one side surface of the ridge, and a ridge striking mechanism for smashing the ridge striking body is provided. A clamping member capable of clamping the one side surface is provided in pressure contact with the upper surface and one side surface of the ridge, and a vibration mechanism for vibrating the clamping member using the power of the traveling machine as a drive source is provided. There is a trimming machine characterized by being configured by arranging a weight body.

[Operation] When traveling on the traveling body, the earth-filling rotor raises the mud on the old ridge, and the upper surface and one side surface of the embankment are struck by the ridge knockers, and the upper surface and the one side surface of the slammed mud have a weight body. It is further tightened by a tightening member that is vibrated by a vibrating mechanism that is disposed and driven by the power of the traveling machine body as a drive source.

[Embodiment] FIGS. 1 to 4 show a preferred embodiment to which the present invention is applied, and FIGS. 1 to 3 show the first embodiment in which 1 is a traveling machine body which is a tractor, and a rear portion thereof. Is connected to the machine frame 3 by the connection mechanism 2, and the earth-moving rotor 5 for raising the mud on the ridge 4 is raised on the ridge in the machine frame 3, and the main shaft 7 of the machine frame 3 is rotated by the power take-off shaft 6 of the tractor. Then, the rotor shaft 9 is rotated by the chain mechanism 8, and the blade portion 10 scrapes up the mud on the ridges.

Further, the ridge striking body 11 is formed in the shape of a rear surface adapted to the upper surface and one side surface of the ridge, and in the ridge striking mechanism, the main shaft 7 is rotated above the machine frame 3 via the chain mechanism 12. A rotary shaft 13 is installed horizontally, a crank 14 is fixed to the rear end of the rotary shaft 13, and two swing links 15 are provided at the lower part of the machine frame 3 toward the ridges 4.
And the ridge striking body 11 is pivotally attached to the tip end of the swing link 15,
A connecting rod 16 is installed between the crank 14 and the ridge striking body 11 so that the rotation of the crank 14 causes the ridge striking body 11 to reciprocally strike.

Further, the tightening member 16 is formed in a cross-section adapted to the upper surface and one side surface of the ridge, and two supporting links 17 are pivotally attached to the machine frame 3 so as to be mounted between the front ends of the supporting links 17. The plate 18 is pivotally connected, and the tightening member 16 is attached to the mounting plate 18 so as to be vertically movable.
A stopper member 19 is attached to the machine frame 3, and a weight body 20 is provided above the clamping pressure member 16 so that the clamping pressure member 16 can vibrate.

Reference numeral 21 denotes a vibrating mechanism. In this case, a driven shaft 22 is laterally provided in the mounting plate 18, a pulley 2 is fixed to one end of the driven shaft 22, an eccentric weight 24 is fixed to the other end, and a pulley is attached to the main shaft 7. 25 is fixed, the belt 26 is wound around the pulley 23 and the pulley 25, the driven shaft 22 is rotated by the rotation of the main shaft 7, and the clamping pressure member 16 is vibrated by the action of the eccentric weight 24.

Further, the tightening member 16 is divided into two parts so that the tightening area can be varied, and the slapping material 27 such as rubber, sponge, bristles or the like is provided on the hitting surface.
Is affixed.

Since the first embodiment has the above-mentioned configuration, when the traveling vehicle body 1 travels along the ridge 4, the earth-filling rotor 5 rotates to raise the mud on the ridge 4 and the like, and the upper surface and one side surface of the earth-filling. Is tightened with the ridge hitting body 11.

The upper surface and one side surface of the embankment that has been struck tight are the pressing members.
The eccentric weight 24 of the vibration mechanism 21 is rotated by the power of the traveling machine body as a driving source, and the eccentric weight 24 vibrates the clamping member 16 to oscillate the clamping pressure. By vibrating the member 16, the upper surface and the one side surface of the ridge are continuously clamped many times, whereby the upper surface and the one side surface of the ridge can be strongly clamped.

FIG. 3 shows the second embodiment. In this case, the difference from the first embodiment is the structure of the vibration mechanism for vibrating the clamping member 16.

In this case, a guide roller 28 is provided so as to project from the machine frame 3, a movable body 29 is movably distributed between the guide rollers 28, and the mounting plate 18 is attached to the tip of the movable body 29.

Also in the second embodiment, the same operational effect as in the first embodiment can be obtained.

It should be noted that, as another embodiment, the earth embossing rotor having a structure in which the rotation axis of the earth embedding rotor 5 is arranged in a direction substantially orthogonal to the ridge forming direction can be applied, and the tightening member 16 is roller-shaped. It can also be applied to

Further, the vibration mechanism 21 can be applied to other mechanical type, electric type, hydraulic type and the like.

The ridge striking structure of the ridge striking body 11 may be a hydraulic mechanism.

[Advantages of the Invention] As described above, according to the present invention, when the traveling machine body travels, the embankment rotor raises the mud on the old ridge, and the upper surface and one side surface of the embankment are slammed by the ridge striking body and the ridge striking body. The upper surface and one side surface of the muddy soil are further clamped by the clamping pressure member that vibrates by the vibration mechanism driven by the power of the traveling machine body, and the ridges are clamped well by the instantaneous multiple vibrations of the clamping pressure member. In addition, since the weight body is disposed on the tightening member, the ridge can be surely clamped with the weight of the weight body, and the ridges can be obtained that much, and the ridge can be obtained. The upper surface and the one side surface can be made smooth, and a strong ridge that does not easily collapse can be obtained.

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