Description

Automatic rice straw grass cutting M / C}

The present invention is rice straw used as livestock forage in livestock farms. Automatic straw straw cutter for easily cutting hay and etc. to a certain size. Two or four, and up to eight rectangular compressed straw bundles (bales) are inserted into the body at the same time to operate the hydraulic cylinder V The present invention relates to an automatic rice straw cutting machine which pushes a bunch of rice straws with a concave-convex conveying plate toward a cutting edge mounted and mounted in a shape, and cuts them to a certain size by the shear force.

In livestock farms that raise cows, milk quality and milking capacity are generally supplied by combining concentrated feedstocks and fiber-rich rice straw, hay, and other feedstocks. By scientifically managing the back, it is trying to achieve economical dairy farming by minimizing nutritional balance and waste of feed.

As such, large-scale livestock and general livestock farms are rice straw with a lot of fiber as the main raw material of forage. Hay is commonly used to help digest livestock and is widely used.

These rice straws are supplied to livestock farmers. Hay and the like are supplied compressed in a rectangular shape to facilitate transportation and storage. When used as food for livestock, the straw bales compressed into squares should be cut into appropriate sizes in order to loosen, coarse, mix well with other ingredients, and feed.

Conventionally, for this purpose, the straw straw was cut using a tool such as a small bean or a rotary saw. In recent years, a hydraulic cutter is used in a more advanced form, but it is easier than a human to use the tool, but only three at one end of the frame It is a hydraulic cylinder equipped with a hydraulic device on the other side, and the other side is a hydraulic cylinder equipped with a hydraulic device. This is a practical situation in the field is difficult to actually work.

In addition, because of its small size, large-scale livestock farming and dairy farming have not been able to meet the throughput. However, the same method and configuration can not achieve the intended purpose only by cutting the cutter only externally. In order to process such a large capacity, a lot of manpower and tools are required, and the working time is long. I had a problem.

Looking at the conventional rice straw cutter in detail, the main body is provided with an input and a guide for inserting rice straw, the motor, fluid tank, etc .; A conveying plate inserted into the guide of the main body so as to be transportable in the feeding part; A hydraulic drive unit connected to a rear surface of the transfer plate to transfer the transfer plate; And a cutting portion formed with a plurality of cutting edges for cutting rice straw.

Thus, the prior art tried to easily cut the straw straw, which was done by hand or a rotary saw, in a mold through a hydraulic cylinder. As a result, it was difficult to expect a uniform and perfect cut without straining the machine.

Therefore, the conventional straw straw cutting machine does not consider the shear force due to its structure and the structure of the machine, so it is necessary to operate for a long time in order to cut the straw to a certain size because there is no safety device during uniform cutting and overload. And there was a problem that the efficiency is lowered and safety is not considered.

The present invention is to solve the above problems of the conventional rice straw cutter, in the rice straw cutter for cutting the straw through the cutting edge with a hydraulic cylinder equipped with a hydraulic device for a smooth cutting of the rice straw bundle,

The straw bales are approached and the cutting edges 14b and 14c located at the left and right ends are first contacted and gradually progressed so that the cutting edges 14 are sequentially contacted and the cutting edges 14a at the center are later contacted. It is to provide an automatic rice straw cutter that maximizes the shearing force on the rice straw bundle and cuts it like a scissors, so that the cutting of rice straw is uniform and accurate under the same conditions, thereby improving productivity and increasing work efficiency.

Another object of the present invention is to produce a conveying mill (Fusher) 13, which plays a major role in cutting into an uneven type, the channel block is pushed between the cutting edge 14 and the cutting edge 14, for example, each fixed When you want to break the thread on the blade, hold the left and right ends and push the thread against the blade to apply a force to the cutting edge 14 when the rice straw touches the fixed cutting edge (14). By sticking out the left and right portion of the conveying plate 13 from the left and right by holding the rice straw and acts as a pull to pull both ends of the thread as easily as possible to achieve the effect of shearing force with less force.

Therefore, the straw bales are cut while passing through the cutting blade 14 and the cutting blade 14 fixedly arranged at regular intervals, thereby increasing the shear force under the same conditions, so that a large amount of straw can be cut at the same time. To provide a cutter.

In addition, the object of the present invention is to cut the left and right side plate from the inside of the machine from the inside of the machine to the discharge portion 16 outside the frame shape of the square discharge portion 16 mounted with a plurality of cutting edges 14 vertically inserted into the cutter end. The tapered type trapezoidal discharge port 16 is gradually widened so that the straw straw is widened at the same time as the cutting, and thus the friction between the straw and the discharge port is minimized, thereby reducing the load on the driving unit. It can also be achieved by an automatic rice straw cutter, characterized in that it comprises the installation of the outlet 16 of the tapered structure.
