Description

[Detailed description of the invention] The present invention is an independent swing suspension type ridge in a ridge leveling machine that forms strong ridges using simple tractor work by simultaneously hitting two surfaces, the ridge top surface and the ridge slope, with strong force in dry fields. The structure of the beating device will be described in detail below with reference to the accompanying drawings showing one embodiment.

A main shaft 7 is mounted on a base frame 2 connected to the rear of a traveling vehicle 1, and a ridge-raising rotor 10 is arranged in parallel on one side of the main shaft 7. For example, the power is divided from the main shaft 7 to the ridge-raising rotor 10.
In this machine, a ridge beating plate 11 is provided behind the base frame 2, a ridge raising rotor 10 is rotated to pile up mud at the edge of the ridge onto the ridge, and the ridge is leveled by the ridge beating plate 11. An independently swingable suspension type holding device c is protruded from, for example, the lower rear side of the base frame 2 toward the ridge, and a swinging arm 21 that swings diagonally up and down toward the ridge corner is attached so as to be freely swingable.

The holding device c has two link rods 23 pivoted substantially parallel to each other with both ends thereof pivoted between a bearing plate attached to the rear lower part of the base frame 2 and a swinging arm 21. It is designed to be movable.

A reciprocating push rod 22 is provided to repeatedly swing the swing arm 21 back and forth, and the base of the reciprocating push rod 22 is connected to the main shaft 7 via a crank mechanism c.

A ridge beating plate 11 having a substantially inverted L-shaped longitudinal section is attached to the ridge side of the swinging arm 21, in which a plate for striking the upper surface of the ridge and a plate for striking the slope of the ridge are connected in a fixed state at a predetermined ridge angle.

The holding device c, the swing arm 21 and the reciprocating push rod 22 are located between the rear upper part of the base frame 2 and the upper part of the ridge beating plate 11.
The ridge beating plate 11 is held in a suspended state by suspending tensile springs 14 for maintaining the total weight balance of swinging members such as the ridge beating plate 11 and the like.

In this case, the tension spring 14 may be suspended between the rear upper part of the base frame 2 and the swinging arm 21.

In addition, sled-like flanges 13 (which may be provided only on the upper plate) are provided in series on the front side edges of the ridge beating plate 11.

In addition, in the figure, reference numeral 15 is a handle, 16 is a support tube,
17 is a striking recoil receiver, and 18 is a dirt cover.

Next, the support device a includes the lifting arm 3, the support rod 4,
Consisting of a connecting rod 5, a lifting rod 6, etc., the base frame 2 is held at the rear of the tractor by this support device a, and the base frame 2 is raised and lowered approximately horizontally by sliding the lifting arm 3 using hydraulic pressure or the like. The figure shows a case in which it is possible to move freely.

In addition, on the main shaft 7 installed in the front and back direction of the base frame 2,
A reciprocating push rod 22 connects joint rods 9 with adjustable joints 8 at both ends to obtain power from a tractor, and provides a ridge-raising rotor 10 and a ridge-beating plate 11 with a tapping action, which are arranged in parallel on one side of the main shaft 7. The power is then separated from the main shaft 7.

In the drawing, a chain transmission device b is interposed between the main shaft 7 and the ridge-raising rotor 10. In addition, the ridge raising rotor 10 has a soil scattering prevention cover 20 on the top.
The rotor part is equipped with a ridge-raising blade 12 formed to surely scrape up the soil of the rice field.

As conventional ridge adjustment machines, the one shown in Japanese Utility Model Publication No. 49-3373 and the one shown in Japanese Patent Application Laid-Open No. 51-141212 are known, but both of these machines are It is a type in which the part is hinged to the fuselage side, and only the rear edge is pressed against the ridge slope by a crank mechanism.It is more like a ridge painting board than ridge pounding, and this ridge painting board is painted by repeated movements. This is a ridge adjustment machine that applies ``mushy beacon'' while pressing it onto the ridge slope.

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 pressure on the surface.

This type of ridge adjustment machine is used in wet rice fields, and in the case of dry fields, water is purposely applied to the edges of the ridges to create a large amount of ``mushy soil'' at the edge of the ridges before the ridges are adjusted.

The present invention eliminates the need for ``creating a muddy surface'' as described above, and in other words, it is possible to perform ridge adjustment work even in dry fields on a sunny day. A main shaft 7 is installed on the base frame 2, and a ridge-raising rotor 10 is arranged in parallel on one side of the main shaft 7.
A ridge beating plate 11 is arranged behind the ridge raising rotor 10, and the ridge beating rotor 10 is rotated to mound the mud at the ridges onto the ridge, and the ridge beating plate 11 is used to level the ridges. Therefore, by simply moving the vehicle 1 forward while rotating the ridge-creating rotor 10, the ridge-creating rotor 10 will dig up the mud and move forward while filling the upper surface and slope of the ridge 19 with appropriate mud. .

Then, this mounded mud is immediately pounded and hardened by a ridge-beating plate 11 installed behind the ridge-raising rotor 10. The first feature of the present invention is the attachment mechanism of the ridge-pounding plate 11, which is attached to the base frame. A swinging arm 21 is attached to an independent swinging suspension type holding device c protruding from the rear part of the ridge 2 toward the ridge side, and the swinging arm 21 is provided so as to be swingable diagonally up and down toward the ridge angle. , the swinging arm 21 is provided to be able to swing back and forth repeatedly by a reciprocating push rod 22 connected to the main shaft 7 via a crank mechanism c', and the ridge striking plate 11 is struck against the ridge when descending during this swinging motion. It is in.

If the ridge beating board 11, which repeatedly swings back and forth in an independently swinging suspended state, is leveled when the ridge is lowered, the ridge striking board 11 will always be struck diagonally downward from diagonally above toward the ridge angle. As a result, a powerful hitting force is instantaneously applied.

In addition, this ridge-beating board 11 is always struck on the entire surface of the board, and with a substantially average striking force, and unlike the conventional ones that strike only at the rear edge or those that press, the action changes to a smearing action as it moves forward. Instead, it involves repeatedly hitting the object with a strong force momentarily.

The second feature is the structure of the ridge beating board 11, in which the plate that strikes the upper surface of the ridge and the plate that strikes the slope of the ridge are fixed at a predetermined ridge angle, that is, they are not in a movable state such as a hinge, but are integrated. Since the ridge beating plate 11 connected in series to the ridge is adopted, it is possible to simultaneously strike two surfaces, the ridge top surface and the ridge slope, and the first feature is a striking action that rapidly descends diagonally from above toward the ridge angle. Since the ridge pounding board 11 and the hard old ridge side strongly sandwich the raised soft mud by pounding the two sides simultaneously, the mud is firmly compacted. As this action is repeated over and over again, extremely strong ridges are created, and insect and mouse holes are reliably blocked.

Furthermore, a third feature is that swinging members such as the holding device c, the swinging arm 21, the reciprocating push rod 22, and the ridge-beating board 11 are provided between the rear upper part of the base frame 2 and the upper part of the ridge-beating board 11. By suspending the tensile springs 14 that maintain balance with the total weight of the ridge-beating board 11 and holding the ridge-beating board 11 in a suspended state, the thick and strong tensile springs 14 are moved in a direction substantially equal to the direction in which the ridge-beating board 11 rapidly descends. Since it is suspended in a well-balanced manner with the total weight of the swinging member, it will swing like a swing even with a slight push by hand, and it will be suspended in a well-balanced manner like this. The first feature, the mounting mechanism, causes the ridge beating plate 11, which is the first feature, to suddenly descend diagonally downward from diagonally upward toward the ridge angle, which is the second feature, resulting in excellent striking behavior due to instantaneous strong impact force. will be carried out.

At this time, this strong hitting action naturally generates a reaction force, but this reaction force is combined with the tensile force of the tensile spring 14 provided in the same direction to quickly return to its original state, allowing it to be hit again by the crank action. , always make effective use of this spring pressure, and repeat excellent hitting behavior with speed.

This is an important factor in creating strong ridges.

The fourth feature is that sled-like flanges 13 are provided on the front side edges of the ridge-beating board 11, and in this invention, the beating behavior is performed in an independent swinging state, but the movement continues as it moves forward. The presence of the sled-like tsuba 13 makes the advance of the hitter extremely smooth.

As described above, this invention can be used not only in wet fields, but also in dry fields in particular, without the need to water the ridges and create ``muddy fields'' as in the past, and to use a tractor on a sunny day when it is easy to work. An independent swinging suspension type ridge pounding device for a practically excellent ridge leveling machine that can easily place new embankment on weakened ridges and transform the embankment into a firmly compacted and durable ridge just by towing the machine. becomes.
