A spring holder having substantially the same shape as the frame 26 fixes a frame 27, and a first anti-contraction spring 28 is installed between the mounting frame 26 and the frame 27, and the first anti-contraction spring 28 always maintains the intermediate position. pipe 9b
is urged toward the ridge side, and when there is a striking reaction force above a certain pressure, the intermediate pipe 9b slides into the upper pipe 9a, and the reaction force is buffered by the first anti-compression spring 28. be.

Further, the second buffer mechanism 12 having the fixing mechanism 11 has a joint pipe 29 inserted through the lower end of the intermediate pipe 9b as shown in FIGS.
It is fixed to the intermediate pipe 9b by a connecting pin 30 inserted from b, and the lower end of the intermediate pipe 9b is slid and inserted into the upper end of the lower pipe 9c located at a predetermined distance,

Furthermore, regulation plates 34 are provided on both sides of the outer peripheral surface of the lower pipe 9C to protrude toward the intermediate pipe 9b, and each regulation plate 34 is provided with a regulation elongated hole 35 extending in the axial direction.
An engagement roller 37 is freely rotatably attached to both ends of the pipe with nuts 36, and the engagement roller 37 is engaged in the regulation elongated hole 35 to regulate the amount of sliding expansion and contraction between the intermediate pipe 9b and the lower pipe 9c. In this way, when the second anti-compression spring 33 generates a knocking reaction force of a certain pressure or more, the joint pipe 29 slides into the lower pipe 9c and the second anti-compression spring 33 buffers the hitting force. Become.

In addition, the fixing mechanism 11 in this figure is arranged so that the fixing pin 3 is placed above the connecting pin 30 and attached to both the regulating plates 34 and the intermediate pipe 9b.
8 is removably inserted into the fixing pin 38, and the retaining pin 3 is inserted into the fixing pin 38.

When inserted, the lower pipe 9c and the intermediate pipe 9b become relatively non-slidable relative to each other, and the intermediate pipe 9b and the lower pipe 9c are integrally connected.

Therefore, the connecting rod 9 is composed of an upper pipe 9a, an intermediate pipe 9b, a joint pipe 29, and a lower pipe 9c, and the lower end of the lower pipe 9c is connected to the ridge beating plate 4 via the actuating plate 19.

In general, the ridge shape, ridge width, and ridge height vary depending on the region, land conditions, etc., and the softness of the mud also varies depending on the land conditions or the weather conditions of the day, and the ridges should be prepared using ridge pounding conditions that correspond to these conditions. is inconclusive.

In view of these points, the present invention includes a rotary shaft 6 installed on the upper part of the machine frame 2, a crank disk 7 fixed to this rotary shaft 6,
A swinging link rod 8 is provided at the lower part of the machine frame 2 so as to be able to swing freely toward the lateral side of the ridge, and the ridge beating plate 4 is attached to the tip of the swinging link rod 8. Since the connecting rod 9 is installed between the crank disk 7 and the predetermined radius position of the crank disk 7, the crank disk 7 rotates due to the rotation of the rotating shaft 6, and the rotation of the crank disk 7 causes the connecting rod 9 to undergo reciprocating pushing motion. Therefore, the ridge beating plate 4 pivotally supported by the swing link rod 8 reciprocates in a direction diagonally downward from the upper corner of the ridge, and this movement is instantaneously repeated by the high speed rotation of the rotating shaft 6. Due to this movement, the mud is instantly compacted by pounding several times, and a good ridge pounding movement is obtained.
is interposed, and furthermore, the second buffer mechanism 12 is interposed between the fixing mechanism 11 and the second buffer mechanism 12 which acts as a buffer when the fixing mechanism 11 is released, so the reaction force due to the ridge striking force is
When the second shock absorbing mechanism 12 is locked by the fixing mechanism 11, the first shock absorbing mechanism 10 acts as a buffer;
By suctioning and suppressing the ridge-beating reaction force, it prevents the strong reaction force from propagating to the crank mechanism part and the machine frame 2.3-point link type coupling mechanism 13 part, thereby preventing damage to these various parts and increasing the lifespan. Not only can the lifespan and durability be improved, but the machine frame 2
The lateral vibration of the tractor 1 is significantly alleviated, and as a result, even though the tractor 1 is moving forward at low speed, there is no unevenness in the hammered ridges, such as leftovers, and the ridges are evenly pounded and compacted with even pressure. This allows for efficient formation of solid ridges.

Furthermore, if the fixing mechanism 11 is released to release the locked state of the second shock absorbing mechanism 12, the shock absorbing effect of the second shock absorbing mechanism 12 acts synergistically with the above-described shock absorbing effect of the first shock absorbing mechanism 10, That is, for example, when the mud is in a hard state, the buffering action of the first buffer mechanism 10 and the second loosening mechanism 12 act synergistically to obtain the above-mentioned optimal buffering action. The ridge pounding pressure and reaction cushioning function can be obtained in accordance with soil conditions such as softness, working conditions, ridge shape, etc., and muddy soil can be pounded and compacted more reliably and better.
Moreover, the ridge adjustment work can be performed more efficiently.

Further, since the entire mechanism is simple and can be implemented by modifying the connecting rod 9 in particular, it is suitable for mass production and can be produced at a correspondingly low cost.

As described above, according to the present invention, the mud piled up on the old ridge can be reliably and well compacted by pounding and compacting according to the soil conditions such as the softness of the mud, the height of the pile, and the working line. This provides a ridge beating device for a ridge shaping machine that has practical effects.
