Description

[Detailed explanation of the invention] This invention changes the leveler, which is attached to the hit part behind the plowing part of a small management machine to perform leveling work, to a groove maker, which is used to create grooves for drainage, etc. This is about a leveler that can be used.

In recent years, small-sized farm management machines particularly suitable for use in small-scale farm fields, such as those used for home gardening and Sunday gardening, have become commercially available.

By the way, this type of small-sized gardening machine is equipped with a low-power engine, and while plowing in a simplified plowing section that is compatible with this engine, it moves forward by the reaction, and its forward force is inevitably weak. Become.

Therefore, the inventors first designed a light-load leveling machine that could be attached to a small control machine to perform suitable leveling work, by fixing two flattening round pipes at an appropriate interval in front and back in parallel to a fixed frame. He proposed a leveling device that was installed in

However, since the attachments of this type of compact management machine for the general public are required to be convenient, there is a desire for the appearance of a leveler that can be changed to one that can perform not only a single task but also multiple tasks. The reality is that there are.

Focusing on the above points, this idea was created by simply replacing the leveling round pipe of the leveler with a sled body, which can be attached to a small control machine to perform suitable leveling work, and can also be used as a groove maker. The aim is to provide a leveling device that can be used.

Hereinafter, specific embodiments of this invention will be described based on the drawings.

The main parts of the leveler according to this invention are a support rod 1 attached to the hit part a of a small management machine, etc., front and rear leveling round pipes 2, 3, sled body 4, these members 2, 3,
It consists of a mounting frame 5 etc. to which 4 is detachably attached,
The lower end of the support rod 1 is engaged in a U-shaped member 6 fixed to the upper surface of the approximately central portion of the mounting frame 5, and is pivotally connected by bolts 7 and nuts 8 so that the front and rear inclination angle 0 can be changed and fixed. There is.

The support rod 1 is made of, for example, a round pipe, a square pipe, a round bar, etc. made of metal or synthetic resin, and is connected to a hit part a by a pin or the like b through through holes 1a, which are bored in an appropriate number at regular intervals above. It is attached removably and can be adjusted to expand and contract in the vertical direction.

The mounting frame 5 is made by bending the left and right sides of the plate-shaped body downward, and attaching two flat round pipes 2 and 3 at appropriate intervals in front and back in parallel to the front and back of both bent lower ends. An arc-shaped notch groove 5a that can be fitted together,
5a, 5b, and 5b are carved, and the front part of the frame body 5 is formed in an inclined shape downward to the right in side view, so that it can be satisfactorily abutted against the upper surface of the sled body 4.

The flattened round pipes 2 and 3 are usually made of, for example, synthetic resin or metal and have a predetermined length. In addition, inside each end of these pipes 2 and 3, there is a round pipe of appropriate length, a telescopic rod 2a made of a round rod,
It is also possible to use a telescopic structure in which the pins 2a, 3a, 3a are inserted and the pins 9 are engaged with appropriately drilled pin holes so as to be adjustable in and out (see Fig. 1).

Then, the flat round pipes 2 and 3 are attached to the mounting frame 5.
The following attachment/detachment structure can be considered to allow attachment/detachment to the cutout grooves 5a, 5a, 5b, and 5b.

FIG. 2 is a cross-sectional side view of a main part showing a first embodiment of this attachment/detachment structure, showing the front and rear recesses 10a, 10b of a pipe attachment wavy band 10 formed by forming a steel band into a roughly wavy shape when viewed from the side.
The central portions of the flattened round pipes 2 and 3 are engaged with each other, and the convex portions 10c, 10d, 10e of the wavy band 10 are connected to the mounting frame 5 using bolts 11 and nuts 12, or the female threaded portions are attached to the mounting frame 5. Screw in the bolt 11'
Fix the flat round pipes 2 and 3 with the mounting frame 5.
It has a structure that engages and fixes it, and can be easily removed by following the above installation procedure and reverse removal order.

3A and 3B are a front view and a side view of the main part showing the second embodiment, and the length is slightly shorter than that between the opposing inner surfaces of the left and right bent parts of the mounting frame 5, and The leveled round pipes 2 and 3 are inserted into tightening fixed pipes 13 and 14, respectively, which have an inner diameter slightly larger than the outer diameter of the leveled round pipes 2 and 3, and the fixed pipe 1
Leveled round pipes 2 near the outer ends of both sides of Nos. 3 and 14, respectively.
3 corresponds to the notch grooves 5a, 5a, 5b, 5b
is engaged with. And fixed pipes 13, 14
Tighten bolts 13a, 14a at the upper center of the outer circumference of
The lower end is fixed by welding or the like, and the bolt through hole 13 is bored in the mounting frame 5 above it.
A nut 13 is attached to the upper end protruding through b and 14b.
c, 14c are screwed in. Therefore, by gradually screwing in the nuts 13c, 14c, the flattened round pipes 2, 3 are first pulled upward together with the fixed pipes 13, 14, and then engaged with the notched grooves 5a, 5a, 5b, 5b. The engaging portions of the flattened round pipes 2 and 3 come into contact with the notched groove and are restricted from being pulled up, and when further screwed in, the fixed pipe 1
Since only 3 and 14 are pulled up, they are strongly pressed and are engaged and fixed. Removal can be easily done by following the above installation procedure and the reverse procedure.

The sled body 4 is a plate-like body having a required width, with its front end tapered and bent upward at a required angle from an appropriate position, and is detachably assembled to the underside of the mounting frame 5. That is, the lower ends of each of the sled body tension fixing bolts 4a and 4b are fixed to a predetermined position on the upper surface of the sled body 4 by welding or the like, and the upper ends of each are made to protrude from the bolt through holes used in the above-mentioned flat round pipe attachment/detachment structure ( The structure is such that nuts 15a and 15b are screwed into each protrusion, and the sled body 4 is tensioned and fixed. Removal can be easily done by following the above installation procedure and the reverse procedure.

As is clear from the above explanation, this invention allows the flattened round pipes 2, 3 and the sled body 4 to be attached and detached from the mounting frame 5 connected to the lower part of the support rod 1. Since it can be used as a leveler or a groove maker during replacement work, it is extremely convenient, and moreover, by combining the leveling work with the leveler and the groove maker, the accuracy of groove creation can be improved.

In addition, when used as a leveler, leveling round pipe 2,
If the telescopic rods 2a, 2a, 3a, and 3a are made into an extendable structure that can be freely adjusted in and out, the leveling work width can be easily adjusted, thereby improving the leveling work efficiency.
