Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention involves embanking soil on ridges in dry rice fields and pounding the embankment with a ridge pounding board that simultaneously strikes two surfaces, the ridge top surface and the ridge slope, to form a strong ridge. This relates to a ridge grading machine that forms ridges using simple tractor work.

[Problems to be solved by conventional technology and invention]

There are two types of ridge adjustment machines: one that creates muddy mud along the ridges in wet fields and smears the mud onto the ridges, and the other that embanks on the ridges in dry fields and compacts the embankment by pounding it.

The ridge leveling machine disclosed in Japanese Patent Publication No. 53-18404 and Utility Model Application Publication No. 53-102411 is of the type that compacts the embankment by pounding it, but the pounding action of the ridge pounding plate is performed by bearings as shown in Figure 4. The support rod that holds the ridge beating plate against the cylinder simply moves back and forth in a straight line.
The ridge pounding board No. 53-102411 hits only the slope of the ridge, so linear reciprocating motion is fine, but the
- In the case of a ridge-beating board that hits both the ridge slope and the ridge top surface at the same time, such as No. 18404, in the case of a linear reciprocating motion, the ridge-beating board that hits the ridge slope must be moved laterally in order to apply sufficient striking force to the ridge-beating board. When a motion is given, the striking board that hits the ridge top surface will slide horizontally on the ridge top surface, and there will be a drawback that it will not be able to hit from the top to the bottom.

The present invention solves this problem by providing a "bowing-like action" to the ridge beating board by reciprocating the ridge beating board in a curved manner as shown in Fig. 3, instead of forcing it to reciprocate linearly. This is what we are trying to solve.

In addition, if the embankment on the ridge before pounding is not good, it will not be possible to create an excellent ridge.

In particular, in the case of a structure in which soil is piled up by a rotor, the soil scraped off by the rotational force of the rotor is likely to be scattered.

In order to prevent this soil from scattering, a ridge coating machine in which the tip of the cover is curved and extended to the top of the ridge so that soil can be filled on the ridge is also disclosed in Japanese Utility Model Application No. 52-41712.

However, since there is a gap between the tip of the cover and the top surface of the ridge, there is a drawback that soil can fly from the gap to the opposite side of the ridge.

The present invention attempts to solve this problem by vertically disposing side covers such that the outer lower end of the cover reaches the upper surface of the ridge.

Furthermore, if the pounding operation of pounding the embankment firmly with a ridge pounding plate placed on the side of the aircraft body is performed continuously while moving slowly, the vehicle will become unstable.

This problem is also attempted to be solved with a striking recoil receiver.

[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.

A main shaft 3 that receives power from the traveling machine 2 is installed on the base frame 1, and a coupling mechanism 4 to the traveling machine 2 is installed on the front part of the base frame 1.
A ridge-raising rotor 5 is installed on the side of the base frame 1, and a soil scattering prevention cover 6 is provided to cover the upper side of the ridge-raising rotor 5 and above the ridge. The lower edge is ridged on the side of
An embankment device b has a side cover 8 vertically long enough to reach the height of the top surface, and a rocking support arm 9 whose base is pivoted from the rear of the base frame 1 and whose tip protrudes toward the ridge 7 side. A ridge beating board holding device c is provided with a swinging arm 10 that supports the ridge beating board, a tip of a reciprocating push rod 12 is connected to the top of the swinging arm 10, and a ridge beating board is attached to the bottom of the swinging arm 10. A tapping device d is attached, and the ridge beating plate is struck in a curved reciprocating locus as shown in FIG. A ridge-beating board e is integrally connected to a ridge-beating board in a fixed state at a predetermined ridge 7 angle, and a support 21 is vertically installed on the base frame 1 at a position apart from the ridge-beating board e, and the base frame is attached to the lower end of the support. The rice field is characterized in that a ridge pounding machine A having a pounding reaction device f having a grounding part that can touch the ground on the surface thereof with its own weight is connected to the rear of the traveling machine 2 so as to be able to rise and fall freely. .

[Effect]

A ridge beating machine A is connected to the traveling machine 2 by a connecting mechanism 4, and the connecting mechanism 4 is set at a predetermined height to slowly move the traveling machine 2 forward along the ridge 7.

The power of the traveling machine 2 is distributed to the main shaft 3 provided on the base frame 1, and this main shaft 3 rotates the ridge-raising rotor 5 attached to the side of the base frame 1, scraping up the soil at the edge of the ridge 7 and scattering the soil. Embankment is carried out on the ridge 7 using the prevention cover 6 and the side covers 8.

The rotation of the main shaft 3 causes the reciprocating push rod 12 to reciprocate using a reciprocating mechanism such as a crank mechanism 11, and the swinging arm 10 attached to the tip of the swinging support arm 9 that swings vertically moves up and down. The ridge beating plate e attached to this swinging arm 10 is given a "bowing-like beating action" with a curved reciprocating locus as shown in Fig. 3 to strongly simultaneously strike both the ridge slope and the ridge upper surface. Beat to harden.

The reaction of the pounding action of the ridge pounding board e is received by the pounding reaction receiving device f, which consists of a support having a grounding part that touches the rice field surface with the weight of the base frame and moves, thereby stabilizing the running of the traveling machine 2. .

〔Example〕

The ridge pounding machine A according to the present invention is equipped with a main device a, an embankment device b, a ridge pounding plate holding device c, a pounding device d, a ridge pounding plate e, and a pounding reaction receiving device f.

The main device a has a main shaft 3 installed in the longitudinal direction of a base frame 1, which receives power from a traveling machine 2 such as a tractor, and a coupling mechanism 4 to the traveling machine 2 at the front of the base frame 1. be.

The embankment device d is provided with a ridge-raising rotor 5 on the side of the base frame 1, and a soil scattering prevention cover 6 that covers the upper side of the ridge-raising rotor 5 and the upper side of the ridge. A side cover 8 whose lower edge is long enough to reach the height of the upper surface of the ridge 7 is vertically disposed on the side cover 8.

The soil scattering prevention cover 6 in the drawings is a case in which a cover with a U-shaped cross section is installed high on the side, and a side cover 8 is installed vertically on the side of this cover.

The ridge beating board holding device c is attached to the ridge 7 from the rear of the base frame 1.
A swinging arm 10 is attached to the tip of a swinging support arm 9 protruding from the side, and a ridge beating plate e is provided on the swinging arm 10 so as to be swingable diagonally up and down.

The beating device d connects the tip of a reciprocating pushing rod 12 to the swinging arm 10, and the reciprocating motion of the swinging arm 12 causes the swinging arm 10 and the ridge beating plate e to move as shown in the locus of FIG. It makes a curved reciprocating movement and performs a ``knocking motion similar to bowing''.

The drawing shows a case where a reciprocating push rod 12 is provided between the swinging arm 10 and the main shaft 3 via a crank mechanism 11, and the swinging arm 10 is provided to be able to freely reciprocate repeatedly by the reciprocating push rod 12. It shows.

The ridge beating board e consists of a board that strikes the top surface of the ridge 7 and a board that strikes the slope of the ridge 7, which are fixedly connected at a predetermined ridge angle, and simultaneously strike the embankment on both sides diagonally. It is a type of hit that is applied from above.

The pounding reaction receiving device f has a column vertically disposed on the base frame 1 and has a grounding part 21 like a tail wheel that can be grounded on the rice field surface with the weight of the base frame 1 at a position away from the ridge pounding plate e. It supports the reaction force of the ridge-pounding action.

The ridge pounding machine A, which is equipped with the above-mentioned main device a, embankment device b, ridge pounding plate holding device c, pounding device d, ridge pounding plate e, and pounding reaction receiving device f, is connected to the rear of the traveling machine 2 so as to be able to rise and fall freely. Then, while moving the traveling machine 2 forward along the ridge 7, the embankment device b embanks the earth on the ridge 7.

This is a ridge leveling machine that hammers and tightens this embankment with a ridge pounding plate e that repeatedly descends diagonally from above toward the ridge angle.

〔Effect of the invention〕

The present invention is not a ridge adjustment machine that creates muddy mud or smears on ridges, but a ridge adjustment machine that can perform ridge adjustment work in dry fields even on sunny days.
Since it is configured as described above, simply moving the traveling machine 2 forward while rotating the ridge-raising rotor 5,
The ridge-creating rotor 5 excavates the soil at the ridge edge and moves forward while heaping the soil on the top and side surfaces of the ridge 7.

Then, this embankment is immediately pounded and hardened by a ridge beating plate e provided at the rear of the ridge raising rotor 5. The first feature of the present invention is that the lower edge on the side of the soil scattering prevention cover 6 is connected to the upper surface of the ridge 7. This is because the side cover 8 is vertically long enough to reach the height of .

The soil scattering prevention cover 6 provided above the ridge-raising rotor 5 prevents the soil dug up by the rotation of the ridge-raising rotor 5 from scattering toward the base frame 1, but this alone does not prevent the soil dug up on the ridge 7 from scattering. I can't make it exciting.

In the present invention, a side cover 8 whose lower edge is long enough to reach the height of the top surface of the ridge 7 is vertically disposed on the side of the soil scattering prevention cover 6, so that the soil dug up by the rotation of the ridge-raising rotor 5 is removed from the side. The side cover 8 ensures that the earth is properly embanked over the ridge top surface and inner ridge slope without scattering to the outside of the ridge position.

Next, the second feature of the present invention is the mounting structure of the ridge beating plate e, in which a ridge beating plate holding device c is provided protruding from the rear part of the base frame 1 toward the ridge side so as to be vertically swingable. A swinging arm 10 is attached to the ridge beating plate holding device c, and a reciprocating push rod 12 for swinging the swinging arm 10 diagonally up and down toward the ridge angle is connected to the swinging arm 10. A ridge beating plate e is attached to the arm 10, and the swinging arm 10
When descending in the swing of
It is at the point where it hits.

That is, the ridge beating plate e of the present invention is suspended in a swinging state.

If a tapping action is applied in this state and the ridges are leveled when the ridge striking board e descends, the ridge striking board e will always be struck diagonally downward from diagonally upward toward the ridge angle, and the hammer action will instantaneously generate a strong force. The striking force is applied in a thud-thump manner.

The third feature of the present invention is the structure of the ridge beating board e, in which the board that strikes the ridge top surface with the entire board surface and the board that strikes the ridge side surface with the entire board surface are fixed at a predetermined ridge angle, that is, the board is fixed. Since we adopted the ridge-beating board e that is connected integrally without being in a movable state, such as hitting the ridge top surface and the ridge side surface at the same time, it is possible to hit the ridge top surface and the ridge side surface at the same time. The ridge pounding board e and the hard old ridge side forcefully pinch the soft mud piled up, so the mud is removed It will be firmly compacted.

Also, it is extremely important that the ridge top surface and ridge side surface be struck at the same time; if only the ridge top surface is struck, the embankment will spill toward the ridge slope.

In addition, if only the sides of the ridge are struck, the embankment tries to escape upwards, making it impossible to firmly compact the ridge corners, which may chip away again, making it impossible to create a sturdy ridge. .

In this regard, in the present invention, the plate that strikes the top surface of the ridge and the plate that strikes the side surface of the ridge are integrally connected, so that the plate that strikes the top surface of the ridge and the plate that strikes the side surface of the ridge sandwich the embankment. Since this is a tapping action, the embankment cannot escape upward or downward at the intersection of the two tapping surfaces on the ridge top surface and the ridge side surface.

In addition, the striking action of the ridge beating plate e repeatedly moves back and forth from diagonally above the ridge corner toward the ridge corner, and the striking action is performed when it descends suddenly, so the strongest impact is applied to the ridge corner. is added, and the ridge corner of the new ridge is pounded down most firmly. For this reason, as mentioned above, the compacted soil is prevented from falling off from the ridge corners, and a firmer and more robust ridge can be created.

In addition, this ridge-beating board e must be struck on the entire surface of the board with a roughly average hitting force, and unlike the conventional type of ridge-beating board that is pressed to open and close the door, the ridges are covered with mud as it moves forward. It is not a coating machine, but rather an instantaneous and repeated tapping action with strong force.

At this time, the top plate and side plate of the ridge pounding board e are connected at angles that match the upper and side surfaces of the new ridge, respectively, so that the ridge that has been pounded and solidified becomes a ridge of a desired shape.

The fourth feature of the present invention is the ridge-beating behavior,
Comparing this with a ridge adjustment machine as shown in Japanese Utility Model Application Publication No. 53-102411, which is a known technology prior to this application, this machine has a cylindrical shape on the machine frame (not shown) as shown in Fig. 4. The bearing cylinder 51 is fixed, and the vibration rod 52 is slidably inserted into the bearing cylinder 51.
A connecting rod 53 is connected to the base of 2, and this connecting rod 53
are connected to the plate surface of the crank 54, while the vibration rod 5
Plate 55, guide rod 56, spring 5 at the tip of 2
A ridge beating plate 58 is attached via a ridge 7, and the crank 54 is rotated to reciprocate the vibrating rod 52, thereby causing the ridge beating plate 58 to move in a linear reciprocating manner to beat the ridges. be.

This item only hits the side of the ridge, not the top of the ridge.

Further, the ridge beating plate 58 moves in a straight line and reciprocates, and does not perform a "bowing-like motion" as in the present invention.

In order to firmly compact the embankment on the old ridge, it is first necessary to pound the top of the ridge strongly from above to below, and this powerful pounding force can cause not only the embankment on the old ridge to collapse, but also to collapse. The existing ridges can be strongly clamped together by the ridge-beating board e and the earth, and it is only through this strong downward force that a firm ridge can be formed. Become.

However, in the conventional example shown in Fig. 4, since there is no upper plate, it is not possible to pound the top surface of the ridge, and only the side surface of the ridge is struck, so the most important ridge corner mentioned above must be firmly pounded. As a result, the embankment tries to escape toward the top of the ridge, making it impossible to compact it firmly.

In this regard, in the present invention, since the locus of the vertical movement of the ridge beating plate e is regulated by the length of the swinging support arm 9, the striking behavior follows the trajectory shown in FIG.

In other words, the ridge-beating board has a locus of curved reciprocating motion, in which the angle of the striking surface gradually changes, just as the ridge-beating board e bows, rather than a straight line reciprocating motion in which the angle of the striking surface does not change as shown in Fig. 4. It becomes e. Therefore, the ridge beating board e hits the ridge top surface and the ridge side surface at the same time, but it also hits the ridge top surface firmly in particular, making the ridge that much more robust.

Even if it were assumed that the conventional ridge beating board 58 in FIG. 4 had a top board attached to it, the top board would simply slide laterally on the embankment and would not function as a beating board.
This is because the ridge striking plate 58 reciprocates in a straight line. This difference in ridge tapping behavior is extremely important for a ridge leveling machine.If the direction of linear reciprocating motion were to strike from directly above to directly below, then the top board would become the striking board. The side board does not become a hammer board,
It becomes a slippery slope.

This means that if you take the middle part and move it linearly back and forth in a 45-degree direction to make both the top and side panels into hitting boards, they will act as both hitting boards and sliding boards at the same time.

As such a sliding plate-like action occurs, the effect of strongly pounding the embankment becomes weaker.

On the other hand, the ridge pounding board e of the present invention is given a ``beating action similar to bowing'', so both the top plate and the side plates act as pounding plates, and the embankment is compacted that much more strongly.

Furthermore, of course, a larger amount of embankment is placed on the top of the ridge than on the slope of the ridge.

Because the embankment on the top of the ridge is pounded with a "knocking motion similar to bowing", the top of the ridge is struck strongly and compacted, and at the same time, the slope of the ridge is also struck, which means that all the embankment is compacted at once. This will ensure that the pores and mouse pores are blocked.

In addition, the structure of the guide section that reciprocates the ridge beating plate 58 in this conventional example is a sliding guide between the vibrating rod 52 and the bearing tube 51, so it is easy to break and even if it is covered with a cover etc., mud etc. can enter. There is also the disadvantage that it becomes difficult to slide, and the linear reciprocating movement of the ridge striking plate 58 cannot be performed smoothly.

In this regard, the present invention simply reciprocates the ridge beating plate e, which is independently suspended so as to be swingable, by the reciprocating push rod 12, and there is no sliding fitting part at all, so it does not have the above-mentioned drawbacks. There will be no.

The fifth feature of the present invention is that the striking reaction receiving device f is provided to support the reaction force of the ridge striking operation, and as described above, the two surfaces of the ridge upper surface and the ridge slope are swingably suspended at the same time. Since the ridge striking board e is momentarily struck with a strong force from diagonally above toward the ridge angle, on the other hand, the strong impact force is applied in the opposite direction as a reaction.

In this respect, the present invention has the advantage that since the grounding part 21 is in contact with the rice field surface with the weight of the base frame 1, there is a frictional resistance between the grounding part 21 and the rice field surface, and a resistance due to the grounding part 21 protruding from the rice field surface. As a result of this action, a reaction force is received, and this reaction force is struck and supported by the reaction receiving device f to maintain stability and smooth the ridge preparation work.

As described above, the present invention eliminates the need to sprinkle water on the edges of the ridges and create "muddy mud" like conventional ridge coating machines, and can be used with a traveling machine like a tractor on sunny days when it is easy to work. Simply by towing the ridge, new mud can be easily embanked on the deteriorated ridge, and the embankment can be simultaneously applied to the ridge top surface and ridge slope using a ridge pounding board that has a top plate and side plates connected together. The ridges are pressed in at the intersection corners of the ridge-beating board, and the ridges are pounded continuously with a strong pounding force while moving forward little by little, creating a firmly compacted and durable ridge that has the correct ridge shape and can be easily and neatly cleaned. This will be a practically excellent ridge adjustment machine.
