Description

[Detailed Description of the Invention] This invention was devised as a work tool for dismantling and cutting grass packed into large packages into arbitrary shapes into small pieces. In recent years, dairy farming has become more mechanized with the development and spread of specialized agricultural equipment, resulting in labor savings in various farming operations. However, on the other hand, there are many cases in which the work is inconvenient unless the work is done skillfully, and a need has arisen for specialized hand tools that are suitable for large-scale mechanical work.

Dry grass is collected and stored using a large packing machine called a baler and divided into small pieces every day to be fed to livestock during the winter.
A sickle, oshikiri, etc. are used. However, all of these tools have different purposes,
Even if it is forcibly diverted, the effect is extremely inefficient,
This work was an area where labor-saving efforts were significantly delayed due to the heavy labor burden. The present invention is intended to sufficiently improve the above-mentioned problems, and embodiments thereof will be described below with reference to the drawings.

1 is a cutter body made of a heat-treated wide special steel strip with a thickness of 1.2 mm, and as shown in Figure 1, it is a double-edged edge with an arbitrary insertion angle for 2.5.
It is supported by a holder 5 via 3 and 4.

2 is symmetrically inserted into the blade body fixing frame, and is held in the center by a blade fixing screw 3 to protect the ultra-thin blade from bending and ensure directional stability when inserted.

4 is a cotter pin with a shape as shown in Fig. 3, which has a small hole penetrating a part of the joint between 2 and 5 so that it can be attached and detached with one touch when polishing the cutting edge or replacing it.It can be easily inserted or pulled out. It is a possible structure.

In order to make it easier for the holder to respond to changes in position during cutting work, 5 has two-hand operation grips arranged symmetrically parallel to 1 as shown in Figure 2, and an upward grip in the middle of the extension. There is.

6 is a foot pedal attached in a downward direction to one end of 5 as shown in Fig. 4, and has a tread area large enough to allow the worker to stably maintain a foot pedal even if he or she puts one foot on the pedal and then puts his entire body weight on it. are doing.

As shown in the plan view of FIG. 2, all of the main parts are arranged in a straight line and symmetrically, so that it is possible to expect effective cutting work efficiency and labor saving with little loss of force.

Claims (1)

[Claims for Utility Model Registration] (1) The tip of the holder 5, which is made of a hollow material and has a width that can be grasped with at least both hands and is shaped like a U-shape in plan, is bent at 90 degrees, and this gap is A plate-shaped petal 6 having a rectangular shape and having an oval hole above the center is adhered to the plate. The back of the blade main body 1, which has a rectangular blade with an inclined tip so as to be located on the plane and center line of the holder, is in a straight line 180 with respect to the holder 5.
A cutter for dismantling packed dry grass, characterized in that it is installed through a hole in a pedal so as to form an angle of . (2) The structure described in claim 1 of the utility model registration, which allows the blade body to be easily attached to and removed from the holder by pulling out the cotter pin 4 when polishing or replacing the blade body 1.
