Description

[Detailed description of the invention] The present invention relates to a ridge adjustment machine.

Conventionally, this type of ridge adjustment machine was developed using the Utility Model 10241 (1983-10241).
Publication No. 1 is mentioned.

As shown in Fig. 4, a cylindrical bearing cylinder 6D is fixed to a machine frame (not shown), a vibration rod (52) is slidably inserted into the bearing cylinder 6, and the vibration rod 5'2 A connecting rod 63) is connected to the base of the vibration rod 52, and this connecting rod 63 is connected to the plate surface of the crank 6, while a plate 55 is connected to the tip of the vibration rod 52.
+, the guide body 66), the ridge beating plate side is attached via the spring 571, and the crank 541 is rotated to reciprocate the vibration rod 62, thereby causing the ridge beating plate (581) to reciprocate in a straight line. It is designed so that it can be pounded against the ridges.

However, in this conventional configuration, the ridge beating board side is @
The line is interlocked with the reciprocating movement, and the space between the ridge-beating boards is a flat plate like a car.
Because its upper edge is slightly curved inward: 2 curves (l/), the plate G with a certain force of 1 (1 ridge μμ) moves back and forth in a straight line toward the ridge corner. Although it will be a criticism, 1.
There was an inconvenience that it was not possible to tighten the ridges firmly enough (2 μIJ).

In other words, the ridge is firmly compacted (firstly, the upper surface of the ridge is strongly struck from above toward the lower edge, and this powerful pl) force (2, therefore, the embankment on the old ridge is Not only that, but old ridges that are about to collapse can also be strongly clamped together by the ridge pounding board and the earth, and therefore, only by this strong downward force can a firm ridge bead be created. However, since this conventional configuration uses diagonal linear motion, the downward force is halved.

Moreover, since the upper edge of the ridge striking plate 58+ is only slightly curved, almost no force is generated to strike the ridge top surface from above to below.

Of course, hitting the sides of the ridge is also an essential condition for obtaining solid ridges, but rather than applying force from the side, it is more important to hit the upper surface of the ridge from above to below to obtain strong ridges. I'm going to make a big color tube for this purpose.

In other words, this lateral force does not cause the clamping to occur, but it is necessary to ensure that the clamped embankment does not try to protrude to the side when struck by the downward force. Although a blocking effect occurs, the magnitude of this lateral hitting force is not a very important condition.

In addition, the structure of the guide section that reciprocates the ridge-beating board of this conventional configuration is a sliding guide with a vibrating rod (52) and a bearing tube 6υ, so it is easy to pry, and even if it is pounded with a cover etc., muddy soil etc. There was also a major disadvantage of using clay, which was that it became difficult to slide due to the intrusion, and the reciprocating motion of the ridge-beating board could not be made smoothly.

The present invention is intended to provide a knurling machine that can eliminate these disadvantages.

The invention will now be described with reference to the accompanying drawings of FIGS. 1 to 3. FIG.

This machine connects a machine frame (3) to a tractor (1) by a coupling mechanism (2), and a ridge rotor (4),
A ridge shaping machine that is equipped with a ridge pounding plate (5), etc., and uses the ridge embankment rotor (4) to heap mud at the edge of the ridge (6) onto the ridge, and then strikes the embankment with the ridge pounding plate (5) to level the ridge. , the ridge beating plate (51) is integrally formed in a shape C that approximately matches the upper surface and one side m1 of the ridge side 1!i surface, and the ridge beating plate (
5) is oscillated from a position above the side of the ridge toward the ridge;
The horizontal upper plate member (7) and the inclined side plate part (
8), at least the horizontal upper plate member (7) has a ridge (6)
This ridge straightening machine is characterized in that it is configured to be able to press the upper surface of the ridge straight down from above to below as much as possible.

Further, this example will be specifically explained.

The coupling mechanism (2) of this embodiment includes lower links (9) on both left and right sides of the rear lower part of the tractor (1), hydraulic arms 00 on both left and right sides of the rear upper part of the tractor (1), hydraulic arms (10) and lower links (9) on both left and right sides of the rear upper part of the tractor (1). ), and an upper link σ2 at the rear middle section, and a machine frame (3) at the tip of the lower link (9) and the tip of the upper link α2.
The structure is such that the machine frame (3) is connected in a three-point supported manner so that it can be raised and lowered freely.

Further, the ridge rotor (4) of this embodiment is horizontally mounted on the eave side position of the machine frame (3), and the ridge rotor (4) has earth raising blades a'' scattered and protruded from the rear. A transmission shaft 0a is disposed in the frame (37), and rotation is transmitted from the power take-off shaft (L6) of the tractor (1) to this transmission shaft (14) with a universal joint (15), and from this transmission shaft ← a sprocket Q7 ) (+8+, Chain (19) cuts and rotates the ridge embankment 1+ -ta (4) downward, that is, rotates clockwise in Fig. 2, scoops up the mud near the ridge, and directly embanks it on the ridge. It is composed of

In addition, in this embodiment, the crank (20) is fixed to the rear end on the nrJ transmission shaft side, and the swing arm υ is pivotally attached to the eave side position of the machine frame (3) by the fulcrum shaft 04. , this swinging arm (
An intermediate arm 03] is formed protruding from 21J, the outer surface of the ridge beating plate (5) is fixed to this intermediate arm (23), and a connecting rod t24 is installed between rank 4 of 1 and the swinging arm υ.
) are pivotally connected.

Since this embodiment has the above configuration, the hydraulic arm (IQ
) moves the machine frame (3) up and down, thereby placing the ridge rotor (4) in a predetermined position, and in this state drives the power take-off shaft α6).

By the rotation of this power take-off shaft (L6), the transmission shaft aa
rotates, thereby, on the one hand, said ridge rotor (4
) rotates, scoops up the mud near the ridge and embanks it, and on the other hand, the crank c! (11 rotates.

By the rotation of this crank (20), the connecting rod 0
24+ reciprocates, and the swinging arm (21J) is pushed and pulled by this connecting rod L24.
oscillates about the fulcrum shaft (221), thereby causing the ridge beating plate (5) to oscillate and interlock from an upper position on the side of the ridge toward the ridge, so that the horizontal upper plate of the ridge beating plate (5) Parts (7
) will be able to press the upper surface of the ridge (6) from above to below as directly downward as possible, and for this reason, not only the embankment on the old ridge but also the old ridge that is about to collapse will be compressed together. A strong centering action occurs between the horizontal upper plate member (7) of the ridge beating board (5) and the ground, and while the slanted side plate member (8) taps and tightens the ridge side, the horizontal upper plate member (7) By pressing down from the sides, the ridge mud that tends to protrude and escape from the side after being pounded with the ridge is made firm and sturdy.

As described above, the present invention provides the ridge beating plate (5) to the ridge (6).
) The bracket is integrally formed in a shape that substantially matches the upper surface and one side surface of the cross section, and the ridge striking plate (5) is swung toward the ridge (6) from a position above the lateral side of the ridge (6). Interlockingly, among the horizontal upper plate member (7) and the oblique side plate member (8) of the ridge beating plate (5),
At least the horizontal upper plate member (7) is configured to be able to press the upper surface of the ridge (6) from above to below as directly downward as possible, so that the upper surface of the ridge (6) can be pressed upward. An increase in the pressing force is brought about by hitting straight downwards from the top, and thereby the embankment on the old ridge and the old ridge that is about to collapse are brought together: The clamping force between the plate member (7) and the ground increases, and this strong clamping creates a solid, dense, and robust ridge, and the slanted plate member (8) also forms a ridge. At the same time, the horizontal upper plate member (7) slams down the sides and firmly catches and holds down the mud that tries to escape from the sides, thereby creating an even more solid and robust ridge. I can do it.

This cannot be achieved by striking using diagonal linear reciprocating motion as in the conventional configuration, and the ridge striking plate (5) is intentionally moved in a swinging motion to strike the ridge top surface by the horizontal upper plate member (7) from above. This can be achieved by configuring the structure so that the force of hitting and squeezing downwards acts as directly downward as possible.
This makes it much better than the conventional configuration. Crisp and dense with no precipitated holes or mouse holes,
Creates strong ridges.

Moreover, since the rocking motion is based on a link structure and a shaft-mounted structure, it moves smoothly even if mud, etc. adheres to it in the form of lumps.
There is no twisting, and there is little friction loss, so further improvements in work efficiency can be expected.

As mentioned above, it is possible to fully achieve the intended purpose.
