Description

[Detailed Description of the Invention] This invention particularly relates to a leveler that can be attached to the hit part behind the tilling part of a small-sized management machine to perform suitable leveling work.

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 kind of management machine is equipped with a low-power engine, and plows in a simplified plowing section that is compatible with this engine, and moves forward by the reaction, so its forward force is inevitably weak. .

Therefore, the inventors first developed a light-load leveling machine that can be attached to this type of control machine to perform suitable leveling work, by fixedly fixing two leveling round pipes at an appropriate interval in front and back parallel to each other. He proposed a leveler that was mounted on a mounting frame.

However, even when leveling work is performed using this type of control machine equipped with this leveler, the leveling width cannot be adjusted and remains constant, and the operator who operates the handle of this machine is unable to balance the leveling width. Immediately after work, the worker had to step on the soil surface that had been leveled, which caused problems such as the inability to achieve a suitable leveling effect. The above-mentioned problems are also the same in conventional plate-shaped flat plates.

This invention aims to solve the above-mentioned problems by providing a leveling device in which a leveling round pipe can be slid and fixed in the left and right directions with respect to a mounting frame.

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

The main parts of the leveler according to this invention include a support rod 1 that is attached to the hit part a of a small management machine, etc., a mounting frame 2, front and rear leveling round pipes 3, 4, right and left slide change fixing means 5, etc. The lower end of the rod 1 is engaged in a U-shaped member 6 fixed to the upper surface of the approximately central portion of the mounting frame 2, and is pivotally connected by bolts 7 and nuts 8 so that the longitudinal inclination angle θ can be changed and fixed. There is.

The support rod 1 is, for example, a round pipe made of metal or synthetic resin.
It is made of a square pipe, a round bar, etc., and is attached to the hitch part a by a pin or the like b via an appropriate number of through holes 1a... drilled at regular intervals on the upper part so that it can be freely attached and detached and can be freely adjusted in the vertical direction.

The mounting frame 2 is made by bending the left and right sides of the plate-shaped body downward, and engaging two flat round pipes 3 and 4 at appropriate intervals in front and back parallel to the front and back of both bent lower ends. Arc-shaped notch grooves 3a, 3 that allow
a, 4a, 4a are engraved.

The leveled round pipes 3 and 4 are made of, for example, synthetic resin or metal round pipes, and are configured to be slidable and fixed in the left and right directions, respectively, by means of a left and right slide change fixing means 5 as appropriate to the mounting frame 2. .

The left and right slide changing fixing means 5 may be, for example, a portion between the opposite inner surfaces of the left and right bent portions of the mounting frame 2.
Slightly shorter or eye length, and a level round pipe 3,
4 Front and rear flat round pipes 3, 4 are installed inside the tightening fixed pipes 9, 10 which have an inner diameter slightly larger than the outer diameter.
are inserted through the fixed pipes 9 and 10, respectively, and corresponding portions of the flattened round pipes 3 and 4 near the outer ends of both sides of the fixed pipes 9 and 10 are engaged with the cutout grooves 3a, 3a, 4a, and 4a, respectively. The lower ends of tightening bolts 9a, 10a are fixed to the upper center of the outer circumference of the fixed pipes 9, 10 by welding or the like, and are passed through bolt through holes 9b, 10b drilled in the mounting frame 2 above them. It is conceivable that nuts 9c, 10c are screwed into the protruding upper end. Therefore, by gradually screwing in the nuts 9c, 10c, the flat round pipes 3, 4 are first pulled upward together with the fixed pipes 9, 10, and then they are engaged with the notched grooves 3a, 3a, 4a, 4a. The engaging portions of the flat round pipes 3 and 4 come into contact with the notch groove and are restricted from being pulled up, and when further screwed in, the fixed pipes 9 and 1
Since only 0 is pulled up, it is pressed strongly and is engaged and fixed. Next, in order to slide the flattened round pipes 3, 4 in the left and right direction, loosen the nuts 9c, 10c and lower the fixed pipes 9, 10. The engaged and fixed state will be released, so the fixed pipes 9, 10 will move inside the fixed pipes 9, 10. The flattened round pipes 3 and 4 can be easily slid to the left and right to desired positions, respectively, and after this change in movement, screwing in the nuts 9c and 10c again engages and fixes them at the changed positions.

When in use, the leveling round pipes 3 and 4 can be slid in opposite directions and engaged and fixed as shown in Figure 4A, and the leveling width w can be expanded to perform leveling work. As shown in B and C, both pipes 3 and 4 are engaged and fixed by sliding them to the right or left, and the worker who operates the handle of the management machine, etc. can walk to the left or right without stepping on the soil surface during leveling work. This is what happens.

As explained above, this invention has two flattened round pipes 3 and 4 spaced apart from each other in front and back parallel to the mounting frame 2 so that they can be slid and fixed in the left and right directions. Compared to the type type, the leveling width w can be expanded easily and the leveling work efficiency can be increased, and both the leveling round pipes 3 and 4 can be slid in the same direction to the right or left. During leveling work, the worker can walk to the left or right to avoid stepping on the soil surface after leveling work, so that suitable leveling work can be performed at the same time as the field is sequentially tilled back and forth.
