Description

[Detailed description of the invention] The present invention relates to a ridge beating device of a ridge adjustment machine that can reliably and well compact mud piled up on a ridge with a ridge beating plate, and the attached drawings show one embodiment. The detailed configuration is as follows with reference to .

While moving forward along the ridge 1, mud is piled up on the top of the ridge, and the raised mud is pounded and compacted with the ridge pounding board 2.
In a ridge adjustment machine designed to level ridges, a rotating shaft 4 is installed on the upper part of a machine frame 3.

A crank disk 5 is fixed to this rotating shaft 4.

A swinging link rod 6 is provided at the lower part of the machine frame 3 to protrude sideways toward the ridge side so as to be swingable.

The ridge beating plate 2 is attached to the tip of the swinging link rod 6.

A crank rod 7 is pivotally supported between the attachment part of the ridge beating plate 2 and the crank disk 5 so that the ridge beating plate 2 performs a beating operation toward the ridge corner.

A buffer post material 8 is interposed between the base of the crank rod 7 and a connecting portion protruding from the crank disk 5 to connect the crank disk 5 and the crank rod 7.

It will be explained in more detail. The ridge leveling machine shown in this figure has a machine frame 3 connected to the rear of a tractor 9 so that it can be raised and lowered by a lifting mechanism a. A raising rotor 10 is provided, a soil scattering prevention cover 11 with only the ridge side surface open is provided on the earth raising rotor 10, and the ridge top surface and the ridge slope are pounded and compacted behind the soil scattering prevention cover 11 to form the ridge. The tractor 9 is moved forward along the ridge, and while the tractor 9 is moving forward along the ridge, it is sequentially heaped up the rice field mud along the ridges onto the top of the ridge and on the slope. The figure shows a structure that is installed to straighten the ridges.

Further, in this figure, a soil cover 12 is provided on the side of the soil scattering prevention cover 11 to allow the muddy soil scooped up by the soil lifting rotor 10 to fall onto the upper surface of the ridge and the slope of the ridge.

The transmission mechanism that transmits power to the soil-lifting rotor 10 and rotating shaft 4 shown in this figure has a main shaft 13 installed on the machine frame 3 in the straight direction of the tractor 9, and a universal connection between the main shaft 13 and the power take-off shaft 14 of the tractor 9. Connected by joint 15,
The earth raising rotor 10 is rotated by a sprocket 16 fixed to a main shaft 13 and a chain 17, while the rotating shaft 4 is driven by a sprocket 18 and a chain 19.

In addition, this figure shows that a hanging side part 20 having the same width as the Tsuchiura cover 12 is hung from the ridge 1 side of the Tsuchiura cover 12, and a roller support frame 21 is fixed to the front and rear of this hanging side part 20. A case is shown in which an elevating shaft 22 is slidably inserted into the roller support frame 21, and a bridge-shaped side wall lower plate 23 is provided between the front and rear elevating shafts 22 to slide on the ridge top surface.

In addition, the swing link rod 6 is attached to the mounting plate 24 at the bottom of the machine frame 3.
A large fork-shaped connecting plate 25 is screwed onto the tip of the upper swinging link rod 6 that protrudes from the water, and a small fork-shaped connecting plate 26 is screwed onto the tip of the lower swinging link rod 6. are screwed onto each other, and the respective connecting plates 25 and 26 are connected to the retaining plate 27 by a pivot 28.
The ridge beating plate 2 is fixed to this holding plate 27,
Handle 29. It is fixed by a male screw rod 30 so that it can move up and down slightly.

The buffer post material 8 in this figure is made of rubber, and has a seat plate 31 fixed to the base of the crank rod 7, and a connecting seat plate 32 that is pivoted at a predetermined position on the crank board 5 by a pivot 33. The figure shows a case in which the cushioning post material 8 is interposed between the seat plate 31 and the connecting seat plate 32.

Reference numeral 34 is a return spring.

As described above, in the present invention, a rotating shaft 4 is installed on the upper part of the machine frame 3, a crank board 5 is fixed to this rotating shaft 4, and a swinging link rod 6 is attached to the lower part of the machine frame 3 so as to face the ridge side. Protrudes so that it can swing freely,
A ridge-beating plate 2 is attached to the tip of the swinging link rod 6. A crank rod 7 is attached between the attached part of the ridge-beating plate 2 and the crank disk 5. The base of this crank rod 7 and the crank plate 5 are pivoted so as to
A buffer post material 8 is interposed between the connecting portion protruding from the
Since the crank plate 5 and the crank rod 7 are connected, the crank plate 5 is moved forward along the ridge 1 and mounds up mud on the top surface of the ridge 1, and when the mounded mud is pounded with the ridge pounding plate 2 to compact and form the ridge. 5. Swing link rod6. The rotational motion of the rotary shaft 4 is converted into the oscillating motion of the ridge beating plate 2 by a lever crank mechanism constituted by a crank-to-door.
In other words, the ridge beating plate 2 is given a ridge beating motion to pound and compact the ridge 1 toward the corners of the ridge 1.

Therefore, if the rotating shaft 4 is rotated at high speed, the mud piled up on the ridge 1 will be powerfully and instantly compacted several times.
In other words, a reliable and good ridge-beating motion is applied, and the ridge 1 is sufficiently firmly pressed to become a solid ridge, thereby forming a ridge 1 that fully exhibits the damming effect. become.

At this time, since the buffer post material 8 is interposed between the crank rod 7 and the crank disk 5 that apply the ridge beating pressure to the ridge beating plate 2, the ridge 1 is beaten with a constant ridge beating pressure. In addition to being compacted, the reaction toward the machine frame 3 is suppressed to a small extent, and the ridge beating plate 2 can perform the ridge beating operation favorably and smoothly.

In particular, due to the positional feature that the buffer post material 8 is interposed between the base of the crank rod 7 and the connection part of the crank disk 5, even if the amount of buffering is small when the buffer post material 8 is placed, the ridge The amount of cushioning is expanded at the hitting surface position of the hitting board 2, and an appropriate and sufficient amount of cushioning can be obtained, making it possible to hit the ridges more reliably.

Furthermore, since the crank rod 7 constituting the lever crank mechanism can be moved slightly by extension and contraction as described above, the operation of the elements of the mechanism is extremely smooth, and the ridge beating plate 2 can operate even better and more reliably. It turns out.

As described above, the present invention provides a ridge pounding device for a ridge leveling machine that has excellent practical effects, such as being able to reliably and well compact mud piled up on ridges using a ridge pounding board. That will happen.
