Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ridge adjustment machine that can perform labor-intensive and troublesome ridge adjustment work quickly and efficiently by mechanical work.

The configuration will be described in detail as follows with reference to the accompanying drawings showing one embodiment. A machine frame 2 is connected to a lift arm mechanism a provided at the rear of a traveling vehicle 1 such as a tractor.

The machine frame 2 is provided so as to be freely raised and lowered by the vibration of the lift arm 3 of the lift arm mechanism a.

A main shaft 4 is installed on this machine frame 2.

This main shaft 4 and a power take-off shaft 5 of the traveling vehicle 1 are connected.

A scattering prevention cover 6 with an open ridge side surface is attached to the side of this machine frame 2.

The outer edge of this scattering prevention cover 6 is set at a higher position than the upper surface of the correct ridge 10.

A lifting rotor 7 is installed within this scattering prevention cover 6.

This erecting rotor 7 is provided rotatably by receiving power from the main shaft 4.

± A dam cover 9 with a drainage chamber 8 formed inside is arranged on the side of the scattering prevention cover 6 higher than the soil scattering prevention cover 6,
In addition, the tip edge of the dam cover 9 is extended to a position above the ridge 10.

A hanging side wall 29 is formed to hang down from the tip edge of this soil puddle cover 9.

Behind this dirt cover 9, an inverted L-shaped ridge beating plate 11 that matches the correct upper surface of the ridge 10 and the slope of the ridge 10 is attached to a swinging rod 12 protruding from the machine frame 2 via a swinging arm 27. do.

A connecting rod 26 is connected to the upper part of the swinging arm 27, and a ridge adjustment mechanism b is provided on the machine frame 2, in which the base of the connecting rod 26 is eccentrically pivoted to the crank disk 25, and the swinging arm 27 is repeatedly swung up and down. A return spring 28 is freely provided and is disposed between the ridge beating plate side and the machine frame side for forcibly returning the ridge beating plate 11. The power of this ridge adjustment behavior mechanism b is distributed from the main shaft 4. The lift arm mechanism a in this figure has a lift arm 3 that protrudes from the upper left and right sides of the rear surface of the vehicle 1, and which vibrates due to hydraulic pressure. The middle part of the rod 13 is connected by a hanging rod 14, and the machine frame 2 is pivotally attached to the tips of the left and right support rods 13, and the upper part of the machine frame 2 is pivoted to the middle of the rear surface of the traveling vehicle 1. The distal end of a connecting rod 15 provided therein is pivotally connected.

Therefore, when the lift arm 3 is vibrated, the machine frame 2 is moved up and down.

In this figure, the power take-off shaft 5 of the vehicle 1 and the main shaft 4 are connected by a universal joint 16.

The earth-lifting rotor 7 shown in this figure has earth-lifting blades 17 formed in an inlet shape radially arranged around the outer periphery of a rotor body 19 fixed to a rotor shaft 18 in order to properly scrape up mud.

Further, the earth raising rotor 7 is rotated by a suprocket 20 fixed to the main shaft 4 and a chain 21. The ridge adjustment behavior mechanism b in this figure will be explained.

A rotating shaft 22 is installed on the upper part of the machine frame 2, and this rotating shaft 22 is connected to a sprocket 23 and a chain from the main shaft 4. 24, and a crank disk 2 is attached to the rear end of this rotating shaft 22.
5 is fixed, and the base end of the connecting rod 26 is pivotally attached to this crank disk 25. On the other hand, two swinging arms are attached to the middle side of the swinging arm 27 fixed to the ridge beating plate 11 and the lower part of the machine frame 2. A movable rod 12 is constructed, the -tip of the swinging arm 27 and the connecting rod 26 are pivotally connected, and the ridge beating plate 1 is installed.
A tension spring 28 is suspended between 1 and the machine frame 2.

In other words, the figure shows a case where a screw crank mechanism is used. Therefore, the ridge beating plate 11 repeatedly swings up and down (oscillating motion) by rotating the main shaft 4, thereby pounding and hardening the ridges 10. In addition, this figure shows that the hanging side wall 29 having the same width as the earth basin cover 9 is pivoted to a shaft 30 on the side of the ridge 10 of the soil basin cover 9, and a support cylinder 31 is fixed to the front and rear of this hanging side wall 29. A support cylinder 33 fixed with a bolt 32 is inserted into the support cylinder 31, and an elevating shaft 35 pressed downward by a compression spring 34 is slidably inserted into the support cylinder 33. A bridge-like side wall lower plate 36 having the same width as the hanging side wall 29 is provided between the lifting shafts 35, and a vibrator 37 is fixed to the support cylinder 31, while elongated holes 38 are formed on both sides of the soil pool cover 9. The locking rod 39 is fixed with a bolt 40,
A case is shown in which a pin rod 41 is provided horizontally at the tip of the locking rod 39 and the pin rod 41 is inserted through the vibrator 37.

Reference numeral 42 is a stopper nut. Therefore, the soil raked up by the soil raising rotor 7 will surely fall on the ridge 10 corner.

In addition, a holding cylinder 43 is located on the opposite side of the machine frame 2 from the earth raising rotor 7.
is installed vertically, and within this holding cylinder 43 is provided an adjustment cylinder 45 whose height can be freely adjusted by a handle 44, and an oak board 46 is attached to the lower end of this adjustment cylinder 45. This is to receive the reaction caused by the oscillating motion of the ridge beating plate 11 and to allow the machine frame 2 to travel stably. As conventional ridge leveling machines, the one shown in Japanese Utility Model Publication No. 49-3373 and the one shown in Japanese Patent Application Laid-Open No. 14121-1988 are known, but both of these machines are designed to operate on one side of the front side of the ridge leveling board. The edge is hinged to the fuselage side, and the opposite side is pressed against the ridge side using a crank mechanism to open and close the door. This is a ridge coating machine that applies a thick layer of mud to the sides of the ridge while pressing it in repeated motions. There is also a type, as shown in Japanese Utility Model Publication No. 51-47785, in which a pressure plate is pressed horizontally against the ridge surface using a grooved cam mechanism, but this is also a method of applying mud by force.

In all of these conventional examples, the upper plate slides on the ridge top surface, and is not a striking plate that hits the ridge top surface.

This kind of ridge coating machine is used in wet rice fields.
In the case of dry rice fields, water is sprinkled along the edges of the ridges to create a thick layer of mud before the ridges are painted.

The present invention eliminates the need for muddy mud cultivation, that is, it is possible to perform ridge adjustment work in dry fields even on sunny days. By simply moving the vehicle 1 forward while rotating the rotor 7, the rotor 7 digs up the mud and moves forward while heaping the mud on the top and side surfaces of the ridge 10.

The mounded mud is immediately pounded and hardened by a ridge pounding plate 11 provided behind the earth raising rotor 7. The first feature of the present invention is that the soil scattering prevention cover 6
A soil puddle cover 9 that covers the upper part of the ridge 10 and a hanging side wall 29 are arranged in series on the sides of the ridge 10.

Soil scattering prevention cover 6 installed above the soil lifting rotor 7
Although this prevents the soil dug up by the rotation of the earth raising rotor 7 from scattering toward the machine frame 2 side, it is not possible to heave the soil dug up on the ridge 10 by this alone.

In the present invention, a soil collecting cover 9 is provided on the side of the soil scattering prevention cover 6.
is provided so as to cover the upper part of the ridge, so that the soil dug up by the rotation of the earth raising rotor 7 will not be scattered further than the ridge position, but will be reliably guided into the earth collecting cover 9, and then will be guided downward. Because the soil falls down, the earth is well-filled from the top of the ridge to the inner slope of the ridge.

Next, the second feature of the present invention is the mounting structure of the ridge-beating plate 11, in which a ridge-beating plate holding device is provided protruding from the rear of the machine frame 2 toward the ridge side so as to be vertically swingable. A swinging arm 27 is attached to the beating board holding device, and a connecting rod 26 for swinging the swinging arm 27 diagonally up and down toward the ridge angle is connected to the swinging arm 27. A striking plate 11 is attached, and the swinging arm 27
The point is that the ridge striking plate 11 is struck against the ridge 10 when it descends during the swinging motion.

That is, the ridge beating plate 11 of the present invention is suspended in such a state that it swings freely when pushed downward by hand when no power is being transmitted.

The ridge-beating board 11 is driven and given a beating action to the ridge-beating board 11.
If the ridge is leveled when the ridge is lowered, the ridge striking board 11 will always be struck diagonally downward from diagonally upward toward the ridge angle, and a strong striking force will be applied instantaneously with a thump due to the hammer action. It turns out.

The third feature of the present invention is the structure of the ridge beating board 11,
A ridge beating board 11 is provided in which a board that strikes the ridge top surface with the entire board surface and a board that strikes the ridge side surface with the entire board surface are fixed at a predetermined ridge angle, that is, they are not in a movable state such as a hinge, but are integrally connected. Since it is adopted, two surfaces, the top surface of the ridge and the side surface of the ridge, will be struck at the same time.
Moreover, in synergy with the second feature, the striking action that rapidly descends diagonally from above toward the ridge angle, the two sides are simultaneously pinched and struck, so that the ridge beating plate 11 and the hard old ridge side are heaped up. Since it strongly pinches the soft mud, the mud is 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.

Also, if only the sides of the ridge are struck, the embankment will try to escape upwards, making it impossible to firmly compact the ridge corners.
From there, it will chip and fall again, making it impossible to create a solid ridge.

In this regard, in the present invention, since the plate for striking the upper surface of the ridge and the plate for striking the side surface of the ridge are connected in an eight-shaped manner, the plate for striking the upper surface of the ridge and the plate for striking 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.

Moreover, the ridge beating plate 11 repeatedly moves back and forth from diagonally above the ridge corner toward the ridge corner, and when it descends rapidly, the ridge beating action is performed. A strong impact is applied, and the ridge corner of the new ridge is pounded and hardened the most.

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 11 must be struck on the entire surface of the board, and with a substantially average striking force, and unlike the conventional ridge-beating board 11, which is used to press doors to open and close them, it removes mud as it moves forward. It is not a ridge coating machine that applies the coating, but rather a repeated action of tapping with strong force instantaneously.

At this time, the top plate and side plate of the ridge beating board 11 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 hardened becomes a ridge of a desired shape.

The fourth feature of the present invention is the ridge beating behavior, which is explained in comparison with the ridge leveling machine as shown in Japanese Utility Model Application Publication No. 102411, which is a known technology prior to the filing of this application. As shown in the figure, a cylindrical bearing cylinder 51 is fixed to a machine frame (not shown), a vibration rod 52 is slidably inserted into the bearing cylinder 51, and a connecting rod 53 is connected to the base of the vibration rod 52. , this connecting rod 53 is connected to the plate surface of a crank 54, and a plate 55, a guide rod 56, and a spring 57 are attached to the tip of the vibrating rod 52.
The ridge beating plate 58 is attached through the ridge, 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. .

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 single bowing 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 forcefully from above to the bottom, and due to this powerful pounding force, the embankment on the old ridge is on the verge of collapsing. The old ridges can also be strongly clamped together between the ridge pounding board 11 and the ground, and a firm ridge can only be created if this downward direction is stronger.

However, in the conventional example shown in Fig. 4, since there is no upper plate, it is not possible to hit the top surface of the ridge, and it is only possible to hit the ridge surface. Since the most important ridge corner mentioned above can be firmly compacted by simply pounding the ridge, the embankment tends to escape toward the top of the ridge.
I can't tighten it firmly.

In this respect, the present invention is designed to improve the length of the swinging rod 12! As a result, the trajectory of the vertical movement of the ridge beating plate 11 is regulated, resulting in the tapping behavior of the trajectory shown in FIG.

That is, instead of the straight line reciprocating motion in which the angle of the striking surface does not change as shown in Fig. 4, the ridge beating has a locus of curved reciprocating motion in which the angle of the striking surface gradually changes, just as the ridge beating board 11 bows. This becomes plate 11.

Therefore, although the ridge beating board 11 simultaneously strikes the ridge top surface and the ridge side surface, it becomes the ridge striking board 11 that hits the ridge top surface firmly in particular, making the ridge that much more robust. This fourth
Even if it were assumed that the conventional ridge beating board 58 shown in the figure was attached with a ceiling board, the ceiling board would simply slide laterally on the embankment and would not function as a striking board.

This is because the ridge striking plate 58 reciprocates in a straight line. This difference in ridge tapping behavior is extremely important as 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, but the side boards would not become the striking board, but instead would become sliding boards. This means that if you take the middle part and move it back in a straight line in the four-way direction to make both the top board and the side board into a hitting board, they will act as both a hitting board and a sliding board at the same time. .

The more this type of sliding plate-like action occurs, the less effective it is to pound the embankment to harden it.

On the other hand, the ridge pounding board 11 of the present invention is given a tapping motion similar to bowing, so both the top board and the side boards act as beating boards, 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 struck in a tapping motion similar to a bowing, the top of the ridge is struck strongly, 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 8 cannot be smoothly performed.

In this regard, the present invention does not have the above-mentioned drawbacks because the ridge beating plate 11, which is independently suspended in a swingable manner, can be moved back and forth on the connecting rod 26, and there is no sliding fitting part at all. become.

Furthermore, the fifth feature of the present invention is that the ridge beating plate 11 side and the machine frame 2
A return spring 28 for forcibly returning the ridge-beating plate 11 is disposed between the side and the ridge-beating plate 11, so that the ridge-beating plate 11 is forcibly returned by the return spring 28. The ridge beating plate 11 returns instantly and moves forward again to strike and tighten the ridge 10, so as the number of strikes increases, the efficiency of striking improves, and the returning spring 28 causes the ridge to be moved back strongly. Since the coming ridge beating board 11 is pushed back all at once and moved forward, a large impact force is generated on the ridge striking board 11, and the inertia force increases accordingly, and the ridge 10 is struck with this so-called impactful strong force. It will be tightened,
As a result, even firmer ridges 10 can be obtained.

Moreover, even if the ridge 10 is strongly struck by the ridge beating board 11 and as a result, mud is strongly attached to the ridge striking board 11, the ridge striking board 11 is forcibly moved by the return spring 28.
0, thereby allowing smooth reciprocating motion,
Workability is improved, and damage to the mechanism and the like can be prevented. Further, the return spring 28 is connected to the ridge striking plate 1.
Even if there is a weight of 1st grade, the ridge beating plate 11 is held at or near the return position in a stationary state, so that work efficiency can be improved accordingly.

As described above, the present invention eliminates the need to sprinkle water on the edges of the ridges and create muddy mud as in the case of conventional ridge coating machines. 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 ridge-beating board is inserted into the intersecting corners of the ridge-beating board, and the ridges are pounded continuously with strong thumping force while moving forward little by little, making it possible to easily and neatly create strong ridges with the correct ridge shape. This will be an excellent ridge adjustment machine in practical use.
