Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a double-acting device for land leveling equipment, and particularly to a double-acting device for land leveling equipment for leveling playgrounds, farmland, etc.

[Prior Art] Conventionally, as a ground leveling device, for example, there is one in which a leveling plate is fixed to the tip of a grippable operating rod, and the surface of the leveling plate and the axis of the operating rod are in a constant angular relationship. It's summery. And when leveling the ground,
The operating rod is set at a predetermined angle to the ground so that it is easy to hold, and the ground is leveled by pulling or pushing and scraping the ground with the lower edge of the ground leveling plate.

[Problem to be solved by the invention] By the way, in the case of the above-mentioned conventional land leveling equipment, the angle of depression of the leveling plate with respect to the ground is adjusted when increasing the amount of ground to be removed.
Since this depression angle adjustment is performed by changing the angle of the operating rod with respect to the ground, there is a problem in that the operating rod may become difficult to hold, impairing workability. Additionally, if the ground leveling plate is fixed at a predetermined angle of depression while keeping the angle of the operating rod to the ground constant, work at the predetermined angle of depression can only be done by either pulling or pushing. Therefore, when leveling the ground by going back and forth, the orientation of the ground leveling equipment must be changed each time, resulting in extremely poor work efficiency.

This invention was created in view of the above problems, and the problem was to make it possible to adjust the angle of depression,
Moreover, the purpose of the present invention is to provide a double-acting device for ground leveling equipment that can easily set the depression angle to be approximately the same whether the operating rod is pulled or pushed, improving the ground leveling function and improving work efficiency. do.

[Means for Solving the Problems] The technical means of the present invention for solving such problems is to support a ground leveling plate at the tip of the operating rod so as to be rotatable about an axis parallel to its longitudinal direction. This is a double-acting device for ground leveling equipment, which includes a bearing plate provided on the back surface of the ground leveling plate and provided with a bearing hole, and two outer parts provided at the tip of the operating rod and facing the back side of the ground leveling plate. a coupling member having an angle portion having a side surface and pivotally supporting the bearing plate; a shaft protruding from a corner of the angle portion of the coupling member and inserted into a bearing hole of the bearing plate; and two of the angle portions. The ground leveling plate is provided with a stopper provided on each of the two outer surfaces and abutting against the rear surface of the facing ground leveling plate to position the ground leveling plate and adjusting the depression angle of the ground leveling plate with respect to the ground.

[Example] The double-acting device for earth leveling equipment of the present invention will be described below based on the accompanying drawings.

As shown in FIGS. 1 and 2, the reciprocating device for the earth leveling equipment according to the embodiment has a ground leveling plate A attached to the tip of an operating rod B so as to be freely rotatable about an axis parallel to its longitudinal direction. I support it.

To explain in detail, on the back of the above ground leveling plate A,
A bearing plate 2 provided with a bearing hole is provided.

On the other hand, a connecting member C for pivotally supporting the bearing plate 2 is provided at the tip of the operating rod B. The connecting member C has an angle portion 4 having two outer surfaces that can face the back surface of the ground leveling plate A, and
and an extension portion 5 connected to the operating rod B and extending along the axis of the operating rod B, and fixed with screws or the like.

A shaft 1 that is inserted into a bearing hole of the bearing plate 2 is provided at a corner of the angle portion 4 of the coupling member C. Furthermore, stoppers 3 and 3' for positioning the ground leveling plate A by coming into contact with the rear surface of the facing leveling plate A are provided on the two outer surfaces of the angle portion 4, respectively. The stoppers 3, 3' are comprised of, for example, bolts that are screwed into the angle portion 4 and whose protruding dimensions can be adjusted. It is now possible to adjust α.

Therefore, when using this soil leveling equipment, adjust the stoppers 3, 3' appropriately and, for example,
As shown in Fig. 2 and Fig. 2, for example, at a predetermined angle θ of the operating rod B with respect to the ground, such as an angle at which the operating rod B is easy to hold, the depression angle α of the ground leveling plate A (the angle of the leveling surface or plowing surface with respect to the ground) ) is set to be approximately the same angle when the ground leveling plate A is located on one side and when it is located on the reversed other side.

Even when using ground leveling equipment, leveling of the ground is done manually or by other power sources. First, as shown in FIG. 1, the ground leveling plate A is brought into contact with one of the stoppers 3, and in this state, the operation B is pressed to level the ground.
In this case, the leveling plate A scrapes the ground at a predetermined angle of depression α, so that the unleveled surface D becomes a flat leveled surface E.

When you reach your target, pull control rod B. As a result, as shown in FIG. 2, the ground leveling plate A rotates around the shaft 1 and comes into contact with the other stopper 3'. Then, in this state, pull the operating rod B to level the ground. In this case, the leveling plate A scrapes the ground at a predetermined angle of depression α, so that the unleveled surface D becomes a flat leveled surface E.

[Effects of the invention] As explained above, according to the double-motion device of the present invention, the angle of the operating rod with respect to the ground can be kept constant and the angle of depression of the leveling plate with respect to the ground can be adjusted. The degree of scraping of the ground can be controlled, and the leveling function can be improved accordingly. In addition, whether you are pulling or pushing the control rod, you can rotate the ground leveling plate and set it to approximately the same depression angle, so you can level the ground by going back and forth while keeping the angle of the control rod to the ground constant. ,
Therefore, workability can be greatly improved.
