Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a ridge beating device in a ridge adjustment machine for forming old, low ridges into desired new ridges.

[Problems to be solved by conventional techniques and ideas]

The ridge-pounding plate used in a ridge-leveling machine that compacts soil piled up on old ridges to level the ridges is one in which a top plate and a side plate are connected in a vertical cross-sectional shape according to the cross-sectional shape of the ridge, as shown in Japanese Patent Publication No. 18404/1983. It is set up.

The ridge leveling machine of the present invention does not hammer and compact the embankment on the ridge by reciprocating the ridge pounding plate while it is stopped, but continues to move slowly forward and at the same time causes the ridge pounding plate to reciprocate to perform the ridge pounding operation. This is a type of ridge adjustment machine.

Therefore, even at the moment when the embankment on the ridge is pounded and compacted with the ridge pounding board, the machine frame continues to move forward, so the front edge of the ridge pounding plate (the front side in the forward direction) may dig into the embankment that has not yet been pounded and compacted, or scrape the ridge soil. There is a risk that this will occur.

This kind of action acts as resistance to the reciprocating movement and forward movement of the ridge-beating board, so if the ridge-beating board continues to receive such resistance while leveling the ridges, some part of the ridge-leveling mechanism will become strained, and the ridge-leveling machine will stop working. The disadvantage is that it cannot be used for a long time.

[Means for solving problems]

The present invention solves these drawbacks, and its structure will be described in detail below with reference to the accompanying drawings showing embodiments.

In a ridge leveling machine that forms new ridges 2 by embanking on old ridges and compacting this embankment with a ridge pounding plate 1 provided on a machine frame 4 that slowly moves forward, the ridge top surface of the ridge pounding plate 1 is pounded and compacted. A top pounding plate part a and a side pounding plate part b for pounding and hardening the ridge side surfaces are integrally connected at an angle that matches the angle formed between the top surface and the side surface of the ridge in a fixed state with a vertical cross section, and this ridge pounding is performed. At the front edge of the plate 1 in the forward direction, a flange plate 18 bent with respect to the surface of the ridge-beating plate 1 is integrated with the ridge-beating plate 1, and the flange plate 18 is attached to the top-beating plate part a and the flange plate 18 is attached to the side-beating plate part b. The ridge-beating plate 1 is provided so as to protrude in a continuous manner with the flange plate 18, and the ridge-beating plate 1 is provided so as to perform a reciprocating striking motion from diagonally above the ridge corner toward the ridge corner, and is grounded to support the reaction force generated by this striking behavior. A reaction support 20 with a wheel 19 rotatably provided at the lower end is attached to the ridge hitting plate 1 of the machine frame 4.
It is characterized by being vertically installed at a more distant position.

[Effect]

The ridge leveling machine of the present invention is moved slowly along the old ridge while embanking on the old ridge, and at the same time, the ridge pounding board is moved back and forth from diagonally above the ridge corner toward the ridge corner in a reciprocating action. The heaped embankment is sandwiched between the top and side pounding plates of the ridge pounding plate and is pounded and compacted by both surfaces, and new ridges are continuously created.

〔Example〕

The ridge adjustment machine shown in the drawings has a main shaft 5 mounted on a machine frame 4 connected to the rear of a traveling vehicle 3.

The drawing shows a lifting arm 6, a support rod 7, a connecting rod 8,
The machine frame 4 is held at the rear of the tractor by a support device c composed of a lifting rod 9, etc., and the machine frame 4 can be raised and lowered approximately horizontally by sliding the lifting arm 6 using hydraulic pressure or the like. The diagram shows the case where

The drawing also shows a joint rod 1 with a main shaft 5 installed in the front-rear direction of the machine frame 4 and a universal joint 10 provided at both ends.
1 is connected to obtain power from the tractor,
A case is shown in which the main shaft 5 is rotated.

On one side of the main shaft 5, a ridge-raising rotor 12 is installed which separates the power from the main shaft 5.

The drawing shows a case where a chain transmission device d is interposed between the main shaft 5 and the ridge-raising rotor 12.

Further, the ridge-raising rotor 12 shown in the drawing is provided with a soil scattering prevention cover 13 on its upper part, and the rotor portion is equipped with a ridge-raising blade 14 formed to reliably scrape up soil in the rice field.

A holding device e is provided protruding from the rear of the machine frame 4 toward the ridge side so as to be vertically swingable.

This holding device e has two link rods 1 between a bearing plate attached to the rear lower part of the machine frame 4 and a swinging arm 15.
The figure shows a case in which the shafts 6 are oriented substantially parallel to each other and are pivoted at both ends thereof so as to be swingable.

This swinging arm 15 is provided with a reciprocating push rod 17 that swings the ridge beating plate 1 diagonally up and down toward the ridge angle.
will be established.

The drawing shows a case where the base of this reciprocating push rod 17 is connected to the main shaft 5 via a crank mechanism f.

On the ridge side of the swinging arm 15, a top pounding plate section a for pounding and hardening the upper surface of the ridge with the entire surface of the plate and a side pounding plate section b for pounding and hardening the ridge side surface with the entire surface of the plate are connected in a fixed state at a predetermined ridge angle. A ridge beating plate 1 is attached to the swing arm 1.
The ridge beating plate 1 is provided so as to perform a bowing-like beating behavior against the ridge 2 by the swinging motion of step 5.

The bending angle of the brim plate 18 is set so that the front edge of the ridge-beating plate 1 in the forward direction does not dig into the embankment or scrape the top of the ridge 2, and pushes the embankment or ridge soil into the inside of the ridge-beating plate 1. Any angle that allows movement is fine.

The ground wheel 19 is shown in the case where a unicycle is adopted, but the height relative to the machine frame 4 is adjusted by the handle 21.
It may be possible to make the adjustment possible.

[Effect of idea]

The ridge leveling machine of the present invention moves slowly forward while moving the ridge beating plate back and forth from diagonally above the ridge corner toward the ridge corner. Because they are integrally connected in a shape, the top pounding plate part and the side pounding plate part sandwich the embankment to pound and harden the embankment on the ridge. In some areas, the embankment cannot escape upwards or downwards,
That will make it more solid.

Moreover, the front edge of this ridge beating board in the forward direction has a flange plate bent with respect to the ridge beating plate surface, which is integrated with the ridge beating plate, and a flange plate for the upper surface beating plate part and a flange plate for the side beating plate part. Because they are connected and protrude, the flange plate stands up on the front edge of the ridge-beating plate and is bent like a wall, so the moment the ridge-beating plate starts hitting, the aircraft continues to move forward. However, the front edge does not dig into the embankment or scrape it, and because the collar plate acts like the sled at the tip of a ski, it is possible to move forward while hitting it. This not only helps to compact the embankment well, but also serves as a reinforcing plate for the ridge pounding board itself. The durability is good, the forward resistance is reduced, and no unreasonable force is applied to the ridge adjustment mechanism, so the ridge adjustment machine can be used for a long time.

Furthermore, this collar plate is installed on the front edge in the direction of movement of the ridge-beating board, and is a wall surface with a rising width, so when filling an old ridge with a rotor, etc., the scattered soil will fly toward the ridge-beating board. It also has the function of preventing soil scattering by blocking the dirt, and also has the feature of serving as a part of the rear wall of the soil scattering prevention cover.

In addition, extremely strong ridges are created in this way, but in order to do so, the striking force must be as strong as possible, but in this case, the reaction force of the striking force always acts on the machine frame, and this The reaction force causes the machine frame to rattle.

In this regard, in the present invention, a reaction support with a grounding wheel rotatably provided at the lower end is installed vertically at a position away from the position of the ridge pounder, so this reaction support also serves as a holding bar, and the ridge pounder is The reaction force when the plate hits the ridge is always supported by this reaction support, which prevents the machine frame from rattling, and conversely, the strong hitting force is created by the reaction support firmly supporting the machine frame. can be given.

Moreover, since the ground wheel was rotatably installed at the lower end of this reaction support, the reaction support supported the machine frame and at the same time served as the tail wheel of the traveling vehicle, and it also supported the ridge-hitting reaction well. This is a ridge beating device for a ridge leveling machine that exhibits excellent practicality, such as good running stability and excellent ridge leveling work.
