Description

Cutting device for rice straw

The present invention relates to a straw straw cutting machine, and more particularly, by automatically cutting and cutting the straw wrapped in a cylindrical shape in a continuous manner, it is possible to significantly reduce the labor force caused by cutting straw straw and to increase the intake by cutting to a length suitable for livestock The straw straw cutter which can be made.

Generally, rice straw refers to stems that have fallen off the rice after the autumn harvest has been completed. These rice straws have been cut to a certain size using conventional soybeans and then mixed with soybean pods and used as food for livestock. However, in the case of cutting rice straw by using soybean, not only the cutting length is not constant, but there is a problem that farmers recklessly use the soybean due to lack of time and labor in farms that raise livestock in large quantities.

Recently, a variety of cutters for automatically cutting rice straw have been developed to solve the above problems. These cutters perform the cutting operation while forcibly conveying the straw bales processed into square or cylindrical shape to the fixed blade or the rotating band saw side.

However, the above-mentioned conventional cutters can be smoothly cut into a relatively small bundle of rice straw, but there is a problem that the blade is blunted or damaged due to the excessive load transmitted to the blade to cut the cylindrical straw that usually weighs 400 to 500 kg or more. . In addition, the conventional cutter is required to put a bunch of rice straw on the cutter by hand manually, a large number of workers are required, there is a problem that can not be cut to a good length to eat livestock.

The present invention is devised to solve the conventional problems as described above, the purpose of the present invention is to automatically cut while unwinding the straw bales wound in a cylindrical shape, it is possible to significantly reduce the labor force due to rice straw cutting and livestock intake To provide a rice straw cutter that can be cut to a good length to increase the intake.

Preferably, the interference shaft 190 rotates between the first roller shaft 168a and the second roller shaft 168b in a direction corresponding to the rotation direction of the first rotating belt 172a and the second rotating belt 172b. ) Is horizontally disposed and one end is extended to the second settle plate 164 side. In this case, a plurality of interference protrusions 192 are formed from one side of the interference shaft 190 to the other side on the outer circumferential surface of the interference shaft 190, and the chain 184 on the interference shaft 190 extending to the second settle plate 164 side. The third sprocket 194, which is radially lowered, is mounted on the upper part of the upper side.

Hereinafter, the state of use of the rice straw cutter 100 formed as described above will be briefly described.

Figure 3 is a cross-sectional view showing a state of use of the straw cutter according to the present invention, and Figures 4a and 4b is a view showing a state in which the transfer device is disposed below the cut portion of the straw cutter according to the present invention.

3 to 4B, in order to cut the straw bales wound in a cylindrical shape, first, the straw bales are placed on the upper part of the supply housing 162 of the supply unit 160. At this time, the radial bottom of the rice straw bundle is in close contact with the first rotating belt 172a and the second rotating belt 172b of the first rotating body 166a and the second rotating body 166b. When the straw bundle is in close contact with the first rotating belt 172a and the second rotating belt 172b as described above, the second driving motor 186 is rotated forward or reverse to rotate the first rotating belt 172a and the second rotation. The belt 172b is rotated. At this time, the end of the rolled straw bales are released by the interference protrusion 192 of the interference shaft 190 is guided to the cutting housing 132 side.

The rice straw guided to the cutting housing 132 is rotated by driving of the first driving motor 154 guided between the first cutting shaft 136a and the second cutting shaft 136b and rotated by the first cutting blade 138a. And is cut by the second cutting blade 138b is discharged to the lower portion of the cutting housing 132. At this time, a lower portion of the cutting housing 132 may be a conveyor device or a screw feeder with a built-in screw shaft (see Figs. 4a and 4b).

Meanwhile, the straw block cut by the first cutting blade 138a and the second cutting blade 138b is disposed on one side of the first cutting shaft 136a and the second cutting shaft 136b, respectively. It does not discharge to the lower portion of the cutting housing 132 and serves to drop the straw when rotating along the first gap ring 137a and the second gap ring 137b.

As described above, the rice straw cutter 100 according to the present invention is placed on the transfer part 110, the upper portion of the transfer part 110, the first cutting blade 138a, the second cutting blade 138b and the first spacing ring 137a, a cutting portion 130 having a first cutting shaft 136a and a second cutting shaft 136b having a second gap ring 137b formed thereon, and a first cutting shaft 136a and a second cutting shaft 136b. By having a first drive unit 150 for driving a), a supply unit 160 for releasing the straw bales wrapped around the cutting portion 130 and the second drive unit 180 for driving the supply unit 160, In addition to being able to continuously cut livestock to a length that is easy to consume, there is an advantage in that the amount of straw that is discarded during the cutting operation can be significantly reduced.

In addition, since the first cutting shaft 136a and the second cutting shaft 136b on which the first cutting blade 138a and the second cutting blade 138b are formed are limited to the inside of the cutting housing 132, the conventional cutting blade is Compared to rice straw cutter exposed to the outside, there is an advantage that can perform a safe cutting operation.

On the other hand, by forming the connecting ring 120 to be mounted on a conventional tractor or cultivator in the transfer unit 110, there is an advantage that the straw straw cutter 100 can be transferred to a desired position by the user.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the present invention described in the utility model registration claims. It will be appreciated.
