Description

Cutting part of circular rice straw cutter {Chaff cutter}

The present invention relates to a straw straw cutter, and more particularly, by moving the cutting unit equipped with a band-shaped cutting blade up and down, to ensure stability when cutting the cylindrical straw bales and to enhance the appearance of the straw straw cutter In addition, the present invention relates to a cutting portion of a circular straw straw cutter that can facilitate the transportation of the straw cutter.

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. In order to solve the above problems, Utility Model Registration Application No. 2004-18412 filed by the present applicant is disclosed.

4 is a perspective view showing a straw cutter equipped with a conventional cutting unit. Referring to Figure 4, the circular straw straw cutter according to the prior art 50 is a straw straw (R) is placed in the base portion 10, the straw straw (R) placed in the base portion 10 is placed by cutting length It is provided with a pushing portion 20 for transferring, a holding portion 30 for holding the transferred straw bales (R) and a cutting unit 40 for cutting the straw bales (R) transferred by the pushing unit 20. . At this time, the cutting unit 40 has a plurality of cutting links 44 and cutting blades mounted on the cutting links 44 and the cutting links 44 for converting the rotational movement of the cutting driving motor 42 and the cutting driving motor 42 into a linear reciprocating motion ( 46). The cutting unit 40 operates under a state in which the cutting unit 40 equipped with the cutting blade 46, the cutting link 44, and the cutting driving motor 42 rotates to the upper side of the base unit 10. The straw bales R are cut while turning to the lower portion of the base 10.

However, the above-mentioned conventional straw straw cutter 50 has a wide operation because the cutting portion 40 equipped with the cutting blade 46, the cutting link 44, and the cutting driving motor 42 rotates to one side of the base portion 10. In addition to the need for space, as the heavy chain cutting portion 40 rotates, there was a problem that the whole straw cutter 50 is shaken. In addition, since the cutting part 40 is mounted on the base part 10 and rotates, the straw cutter 50 has a wide width, making it difficult to load and transport the loading box.

The present invention has been devised to solve the conventional problems as described above, the object of the present invention is to ensure the stability of the cutting of the cylindrical straw bales by slidingly transporting the cutting unit equipped with a band-shaped cutting blade up and down. In addition, to provide a cutting portion of the round straw straw cutter that can not only make the appearance of the straw cutter beautiful, but also facilitate the transport of the straw straw cutter.

The first cutting link 142a and the second cutting link 142b are provided. At this time, both ends of the first cutting link (142a) and the second cutting link (142b) of the link arm 144, both ends of which are pivotally connected by the third link shaft (h3) and the fourth link shaft (h4). ) And a band saw-shaped cutting blade 146 pivotally rotatable by a fifth link shaft h5 and a sixth link shaft h6 at a lower portion of the first cutting link 142a and the second cutting link 142b. ) Is mounted.

On the other hand, the cutting drive 150 is provided with a cutting drive motor 152 and the rotary arm 158. The cutting drive motor 152 is disposed on the upper surface of the third cutting frame 132c. The rotating disc 156 is mounted on the cutting drive shaft 154 extending from the cutting drive motor 152. The rotary arm 158 is disposed between the rotary disk 156 and the second cutting link (142b). One end of the rotary arm 158 is pivotally coupled to the rotary disk 156 by a seventh link shaft h7 and the other end of the rotary arm 158 is connected to the second cutting link by an eighth link shaft h8. It is rotatably coupled to an upper portion of the fourth link shaft h4 of 142b.

The following briefly describes the operating state of the rice straw cutter 100 formed as described above.

3a and 3b is a view showing the operating state of the cutting unit according to the present invention. Referring to FIGS. 3A and 3B, in order to cut the straw straw R processed into a cylindrical shape, first, the first lifting cylinder 114a and the second lifting cylinder 114b are operated to cut the cutting body 140 and the cutting drive. The cutting frame 130 on which the sieve 150 is mounted is transferred upward. That is, according to the operation of the first lifting cylinder 114a and the second lifting cylinder 114b, the first lifting cylinder rod 116a and the second lifting cylinder rod 116b are extended, and as a result, the cutting frame 130 is It is conveyed upwards.

When the preparation work for cutting the straw bales (R) is completed as described above, the worker operates the pushing unit 20 under the state of placing the straw straws processed in the cylindrical shape on the base part 10 and then the straw bales Guide R to the holding portion 30 and the cutting portion 100 side (see FIG. 1). When the straw bales R are transferred to the holding part 30 and the cutting part 100 by the pushing part 20, the holding part 30 is strongly pressed and gripped by the guided straw bales R first.

When the holding unit 30 grips the straw bales R in this way, the cutting drive body 150 mounted on the cutting body 140 is operated. At this time, the cutting drive motor 152 of the cutting drive 150 is operated to rotate the cutting drive shaft 154 and the rotation disc 156. When the rotary disk 156 rotates as described above, the rotary arm 158 mounted on the rotary disk 156 performs linear reciprocating motion, and the second cutting link 142b connected to the rotary arm 158 performs linear reciprocating motion and The first cutting link 142a connected by the second cutting link 142b and the link arm 144 reciprocates about the first link shaft h1 and the second link shaft h2. At this time, the cutting blade 146 mounted on the lower portion of the first cutting link (142a) and the second cutting link (142b) is a linear reciprocating motion.

When the cutting blade 146 performs a linear reciprocating motion as described above, the first lifting cylinder 114a and the second lifting cylinder 114b slowly return the first lifting cylinder rod 116a and the second lifting cylinder rod 116b. While cutting the straw bales (R). At this time, the cut straw bales (R) is guided along the cutting plate 120 to fall to the cutting plate (120). On the other hand, when the return of the first lifting cylinder rod 116a and the second lifting cylinder rod 116b is completed, the cutting blade 146 is in close contact with the upper surface of the cutting bar 118. As a result, the rice straw disposed below the rice straw bundle R is completely cut between the cutting blade 146 and the cutting bar 118 and guided along the cutting plate 120. That is, the cutting bar 118 serves as a conventional cutting board to smoothly cut the rice straw disposed on the bottom of the straw straw (R).

As described above, the cutting portion 100 of the circular rice straw cutter according to the present invention is mounted on the lifting frame 110, the cutting frame 130 and the sliding frame is moved up and down by the lifting platform 110, the cutting frame 130 And a cutting body 140 having a cutting blade 146 disposed thereon and a cutting driving member 150 for driving the cutting body 140, thereby securing stability when cutting the cylindrical straw bales and Not only can the appearance be beautiful, but there is an advantage of facilitating the transport of the straw cutter.

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.
