  The present invention means rice (hereinafter referred to as “rice”) means seed rice before germination in a state where a mulching film is attached, and rice that germinates and divides after being constructed and settled on the bottom of the rice field. In particular, the biodegradable mulching film for manufacturing the biodegradable mulching film to which the first and second biodegradable mulching films are attached is described. In addition to being spaced apart from the outer peripheral surface of the first rotating portion by a certain length at the portion that contacts the protruding portion protruding from the outer peripheral surface, it is possible to easily apply the adhesive and perforate work by pulling it tightly. So that the rice attachment means is periodically rolled to correspond to the adhesive application interval of the biodegradable mulching film. The biodegradable mulching film on which the rice to be taken up by the take-up part is attached is scattered widely in the take-up part and wound by the rice that has been attached so that the rice can be attached accurately and easily to the site.

The first rotating unit 110 that switches the moving direction of the biodegradable mulching film a that moves while contacting and rotating the biodegradable mulching film a supplied to the film manufacturing apparatus, and the direction switching is performed by contacting the first rotating unit 110. The biodegradable mulching film a is moved while rotating in contact with the biodegradable mulching film a. The second rotating part 120 that switches the moving direction of the biodegradable mulching film a. The direction of movement of the biodegradable mulching film a that moves while rotating in contact with the mulching film a is switched again. It may include a third rotating portion 130 and the third rotating part winding section 150 130 rice a3 past the final winding of the deposited biodegradable mulching films a,.

  The first rotating unit 110 is configured to switch the moving direction of the biodegradable mulching film a that moves while rotating in contact with the biodegradable mulching film a supplied to the biodegradable mulching film manufacturing apparatus according to the present invention. It is formed into a cylindrical rod shape so that it can be easily rotated and abutted against the biodegradable mulching film a to change its moving direction smoothly. It rotates using the power provided from the means 50. In the present invention, in particular, the first rotating unit 110 is not limited to simply switching the moving direction of the biodegradable mulching film a that moves while rotating in contact with the biodegradable mulching film a. 20 and the punching means 30 perform a function of assisting the adhesive application work and the punching work to be performed smoothly. For this purpose, the first rotating part 110 protrudes from the outer peripheral surface by a certain length. The portion of the biodegradable mulching film a that includes the protrusion 111 and contacts the first rotating part 110 and switches the direction is separated from the outer peripheral surface of the first rotating part 110 by a certain length. Of course, it is characterized in that the adhesive application and perforation work can be easily performed at the above-mentioned site by being pulled tightly.

  The protrusion 111 is a portion formed to protrude from the outer peripheral surface of the first rotating portion 110 by a certain length, and more specifically, a first protrusion 1111 that protrudes from the center of the protrusion 111 by a certain length. In addition, the first protrusion 1111 may include second protrusions 1112 that protrude from the left and right sides of the first protrusion 1111 by a predetermined length and protrude relatively shorter than the protrusion length of the first protrusion 1111. The first protrusion 1111 is a portion formed to protrude from the outer peripheral surface of the first rotating part 110, more specifically, at a central part of the protruding part 111, and thereby the first rotating part 110. The part of the biodegradable mulching film a that contacts and rotates contacts with the first protrusion 1111 is not only separated from the outer peripheral surface of the first rotating part 110 by a certain length, but also by being pulled tightly, the adhesive described later As shown in FIG. 3, the applying means 20 can easily apply an adhesive to the portion of the biodegradable mulching film a that contacts the first protrusion 1111. A punching means 30 described later is also shown in FIG. As described above, the biodegradable mulching film a can be easily drilled in the through-hole a1 in a tightly pulled part as well as being separated from the outer peripheral surface of the first rotating part 110 by a certain length. So as to. For reference, when the biodegradable mulching film a is in close contact with the outer peripheral surface of the first rotating part 110, there is a problem that not only the perforation work cannot be performed smoothly, but also the manufacturing cost according to the perforation work increases. The protruding shape of the first protrusion 1111 is preferably chamfered so that both protruding end portions are inclined or formed in a round shape, but this is a biodegradable mulching that rotates by contact. This is to prevent damage to the film a. The second protrusions 1112 are portions that are spaced apart from each other by a predetermined length on the left and right sides of the first protrusions 1111 and protrude to a length relatively shorter than the protrusion length of the first protrusions 1111. Since the two protrusions 1112 are additionally formed, the biodegradable mulching film a that is separated from the outer peripheral surface of the first rotating part 110 by a certain length can be pulled more tightly and can be prevented from being damaged. become able to. It is preferable that the protruding shape of the second protrusion 1112 is also chamfered so that both protruding end portions are inclined or formed in a round shape.

  The second rotating unit 120 is configured to switch the moving direction of the biodegradable mulching film a that moves while contacting and rotating the biodegradable mulching film a that has been switched in contact with the first rotating unit 110. Then, the rice a3 is attached to the adhesive application site a2 of the biodegradable mulching film a, which is normally switched so as to move upward while rotating in contact with the first rotating part 110. For the rice adhesion process for the purpose, and for the purpose of switching the moving direction of the biodegradable mulching film a to the downward moving direction, the second rotating unit 120 is in contact with the biodegradable mulching film a while rotating. The moving direction is switched. Also, the second rotating unit 120 allows the biodegradable mulching film a to be pulled tightly so that the adhesive application process and the perforating process centered on the first rotating unit 110 can be performed smoothly. It also plays an auxiliary role. For reference, the unfolded state of the biodegradable mulching film “a” is once again organized before the rice attachment process is performed on the biodegradable mulching film “a” whose direction has been changed while rotating in contact with the second rotating unit 120. In addition, in order to allow the biodegradable mulching film a to be pulled tightly, a fourth rotation unit 140 may be additionally included between the second rotation unit 120 and a third rotation unit 130 described later. .

  The third rotating unit 130 is configured to switch again the moving direction of the biodegradable mulching film a that moves while contacting and rotating the biodegradable mulching film a that has been switched in contact with the second rotating unit 120. The third rotating unit 130 may be attached to the biodegradable mulching film a so that the step of attaching the rice a3 to the part a2 to which the adhesive of the biodegradable mulching film a is applied can be performed. The direction of the biodegradable mulching film a that moves while contacting and rotating is switched.

  The winding unit 150 is configured to finally wind up the biodegradable mulching film a to which the rice a3 is attached after passing through the third rotating unit 130, and the rice a3 finally wound on the winding unit 150 is If the attached biodegradable mulching film a is spread and applied to the rice field, it becomes possible to cultivate rice by the rice seeding method without raising seedlings or rice planting work. Further, the winding unit 150 does not stop simply winding the biodegradable mulching film a to which the rice a3 is adhered while only rotating, and periodically moves as shown in FIGS. While being rolled up, the biodegradable mulching film a with the rice a3 attached in a row is prevented from being excessively swollen or damaged while being wound, but this will be described later. The description will be made in detail with respect to the take-up unit auxiliary moving unit 530.

  The adhesive application unit 20 is configured to apply an adhesive for attaching rice to the biodegradable mulching film a moved by the moving unit 10, and more specifically, as shown in FIG. The adhesive for rice attachment is applied to the biodegradable mulching film a that rotates in contact with the protrusions 111 (more specifically, the first protrusions 1111 protruding so as to protrude most at the protrusions 111). Therefore, the adhesive applying means 20 can apply the adhesive only to the portion of the biodegradable mulching film a that is formed at a position corresponding to the first protrusion 1111 of the protrusion 111 and is in contact with the first protrusion 1111. The adhesive application unit 210 and the adhesive application unit moving unit 220 that can move the adhesive application unit 20 toward the first rotating unit 110 can be included.

The configuration is such that the adhesive can be applied only to the site, and the end of the adhesive application part 210 is formed in a brush form that can be applied with an adhesive so that the adhesive can be applied easily. In addition, a connecting pipe branched from a container in which the adhesive is stored is connected to the adhesive application unit 210 so that the adhesive can be supplied. For reference, the adhesive application unit 210 includes a separate opening / closing unit that prevents the adhesive from being ejected through the adhesive application unit 210 when the adhesive application process is not performed due to the necessity of work.

  As shown in FIGS. 3 and 4, the adhesive application unit moving unit 220 can move the adhesive application unit 20 so as to approach or move away from the first rotating unit 110. In the present invention, the adhesive applying means 20 is around the biodegradable mulching film a rotating in close contact with the first rotating unit 110 around the first rotating unit 110, more specifically, the first rotating unit 110. Since the adhesive can be applied to the periphery of the biodegradable mulching film a that protrudes most on the outer peripheral surface of the adhesive, the adhesive application means 20 is separated from the first rotating unit 110 by a certain length. 3 to allow contact with the biodegradable mulching film a as shown in FIG. 3, or when the adhesive application process does not proceed, as shown in FIG. Configuration of the adhesive applying means moving unit 220 to make away from the periphery of the rolling portion 110 is required. The adhesive application means moving unit 220 may utilize a configuration such as an electronically controlled hydraulic cylinder.

  The perforating means 30 is configured to perforate the through hole a1 in the biodegradable mulching film a moved by the moving means 10, and more specifically, as shown in FIG. 3, the protruding portion 111 of the first rotating part 110.

The rice a3 is attached to the adhesive-applied part a2 of the biodegradable mulching film a, and the rice a3 can be efficiently attached to the part a2 to which the adhesive is periodically applied at regular intervals. The attachment 40 is for receiving the rice a3 and allowing the received rice a3 to be widely spread and scattered, and the rice receiver 410 to roll periodically to contact the third rotating part 130. And a rice attachment means driving unit 420 that allows the rice a3 to be attached efficiently and easily to the adhesive application site a2 at a predetermined interval of the biodegradable mulching film a that switches the direction. Can.

  The rice receiver 410 accommodates the rice a3 and allows the accommodated rice a3 to be widely spread and scattered, and the biodegradable mulching film a moved by the moving means 10 while being widely spread. In order to attach the rice a3 to the adhesive application site a2, the rice receiver 410 in which the rice a3 is accommodated is formed long in the longitudinal direction so that the accommodated rice a3 can be widely spread and scattered, and has a constant width. It is preferable to form in the form which has.

  As shown in FIGS. 6 and 7, the rice attachment means driving unit 420 periodically rolls the rice receiver 410 and contacts the third rotating unit 130 to switch the direction of the biodegradable mulching film a. The rice a3 can be efficiently and easily attached to the adhesive application sites a2 formed at intervals. For this purpose, the rice attaching means driving unit 420 is provided by the power means 50 described later. A first drive shaft 421 that is rotated by the motive power, a second drive shaft 422 that rotates in conjunction with the first drive shaft 421, and an eccentric connection that deviates from the axial center of the second drive shaft 422. As the second drive shaft 422 rotates, a rolling unit 423 that periodically rolls the rice receiver 410 loaded with the rice a3 can be included.

  The first drive shaft 421 is a portion that is rotated by power provided by the power unit 50 described later, and serves to drive the rice adhering unit drive unit 420 upon receiving power from the power unit 50 described later. Come to fulfill.

  The second drive shaft 422 is a portion that rotates in conjunction with the first drive shaft 421, and the second drive shaft 422 is positioned in parallel with the first drive shaft 421, and the first drive shaft 421. And the gears mesh with each other and receive the transmission of the rotational force of the first drive shaft 421 to rotate in conjunction with the first drive shaft 421. In order to complement the point that it is difficult to stably drive a rolling portion 423, which will be described later, with only the first drive shaft 421, the second drive shaft 422 is formed in two or more, and the second drive shaft 422 is formed. The rolling portion 423 described later can be stably driven by the shaft 422.

  The rolling part 423 is eccentrically connected to the second drive shaft 422 so that the rice holder 410 loaded with the rice a3 is periodically rolled as the second drive shaft 422 rotates. As shown in FIG. 8, one side of the rolling part 423 is connected to the rice pad 410 and the rotating shaft 4231 of the rolling part 423 is deviated from the center of the second drive shaft 422. When the second drive shaft 422 rotates by being eccentrically connected, the rotary shaft 4231 that is eccentrically connected and deviated from the center of the second drive shaft 422 rotates while drawing a circle. Accordingly, the rolling part 423 rotates while drawing a circle. At this time, the rice paddle connected to one side of the rolling part 423 is also provided. As shown in FIG. 6 and FIG. 7, while the rice pad 410 is periodically rolled, the rice pad 410 periodically approaches and moves away from the third rotating unit 130. At the moment of approaching the rotating part 130, the rice a3 loaded on the rice pad 410 and spread widely is fixed to the part a2 to which the adhesive of the biodegradable mulching film a rotating in close contact with the third rotating part 130 is attached. Adhered at intervals. At this time, the period of rotation of the rolling part 423, that is, the period of rolling of the rice pad 410 is the interval at which the adhesive is attached to the biodegradable mulching film a rotating in close contact with the third rotating part 130. Preferably, the rice a3 can be efficiently and easily attached to the adhesive application sites a2 formed at regular intervals in the biodegradable mulching film a.

  The power means 50 is configured to provide power necessary for driving the rice dot seeding decomposition mulching film manufacturing apparatus according to the present invention, and more specifically, the first to fourth rotating parts 110 to 140 of the moving means 10. The power required for driving the winding unit 150 and the rice attachment means driving unit 420 is provided. For this purpose, the power unit 50 is connected to a motor unit 510 that provides power necessary for driving the moving unit 10, the rice attachment unit driving unit 420, and the one end of the winding unit 150. A hydraulic cylinder 520 that moves the portion 150 to the left and right at regular intervals, and a rotation shaft 531 as a center, one side 532 is connected to the other end of the winding portion 150, and the other side 533 is an inclined surface of the rotating cam 534 A winding part auxiliary movement that is connected to the take-up surface 5341 and that turns the winding part 150 left and right at a constant period by rotating the cam 534 to the left and right at a constant period to assist the action of the hydraulic cylinder 520. Part 530 may be included.

  The motor unit 510 is configured to provide power required for driving the moving unit 10, the rice attachment unit driving unit 420, and the like. The driving force generated by the motor unit 510 is generated by connecting the four rotating units 110 to 140, the winding unit 150, the first driving shaft 421 of the rice attachment means driving unit 420, and the like using belts and pulleys. The first to fourth rotating parts 110 to 140 and the winding part 150 of the moving means 10 and the first drive shaft 421 of the rice attaching means driving part 420 are transmitted to the moving means 10 and the rice attaching means driving part 420. And so on.

  The hydraulic cylinder 520 is connected to one end of the winding unit 150 and moves the winding unit 150 to the left and right at a constant cycle. As mentioned in the description of the winding unit 150, If the biodegradable mulching film a to which a3 is attached is simply wound only, the portion where the rice a3 is attached will swell, and the volume of the wound biodegradable mulching film a is excessive. In the present invention, there is a problem that the biodegradable mulching film a itself may be damaged due to the increase in size and the difficulty in transportation and work. The hydraulic cylinder 520 is connected to one end of the part 150, and the hydraulic cylinder 520 moves the one end of the winding part 150 to the left and right at a constant cycle as shown in FIGS. By doing so, the part of the biodegradable mulching film a wound around the winding part 150 to which the rice a3 is attached is not excessively wound only on one side, and can be wound evenly distributed on the left and right. Thus, the above problem caused by the excessive volume of the wound biodegradable mulching film a is solved.

  The winding part auxiliary moving part 530 is connected to the other end of the winding part 150 and is configured to assist the function of the hydraulic cylinder 520 that moves the winding part 150 at a constant cycle. As shown, one side 532 is connected to the other end of the winding unit 150 around the rotation shaft 531, and the other side 533 is connected to the inclined chamfered surface 5341 of the rotating cam 534 to rotate the cam 534. As shown in FIG. That is, as shown in FIGS. 11 and 12, the other side 533 of the winding portion auxiliary moving portion 530 connected to the inclined chamfered surface 5341 of the cam 534 rotates (the driving force for rotating the cam 534 at this time). Is preferably transmitted to the motor unit 510), and periodically moves to the left and right along the inclined chamfered surface 5341. However, as the other side 533 moves to the left and right, the rotating shaft 531 is moved. The other end of the winding unit 150 connected to the left and right sides of the winding unit auxiliary moving unit 530 is also moved to the left and right at a constant cycle. Therefore, as described above, the winding unit 150 that moves to the left and right at a constant cycle by the hydraulic cylinder 520 is also operated at a constant cycle by the operation of the winding unit auxiliary moving unit 530 connected to the other end. Since the winding unit 150 moves left and right, the winding unit 150 is stable and regular as shown in FIGS. 11 and 12 by the operation of the hydraulic cylinders 520 and the winding unit auxiliary movement unit 530 located on both sides thereof. Therefore, it is possible to effectively prevent the biodegradable mulching film a to which the rice a3 that is wound up by performing a left-right interlocking motion of a certain period is attached from being excessively swollen or damaged.

  Hereinafter, a method for producing a rice seed soaking / decomposing mulching film using the rice seed soaking / decomposing mulching film manufacturing apparatus according to the present invention will be described in detail.

  FIG. 13 is a block diagram illustrating steps of a method for producing a rice seed sowing decomposition mulching film according to an embodiment of the present invention. Referring to FIG. 1 to FIG. 13, in the method for producing a rice dot sowing biodegradable mulching film according to one embodiment of the present invention, a moving step (S1) of continuously moving the biodegradable mulching film a unfolded by the moving means 10. , An adhesive application step (S2) for applying the adhesive for attaching rice a3 to the biodegradable mulching film a by the adhesive application means 20; a perforating step (S3) for perforating the biodegradable mulching film a by the perforating means 30; Rice sticking step (S4) for attaching rice a3 to the part a2 to which the adhesive of biodegradable mulching film a is applied by means 40, and the final winding of biodegradable mulching film a to which rice a3 is attached by winding unit 150 A winding step (S5) to be taken can be included.

  The moving step (S1) is performed so that the biodegradable mulching film a unfolded by the moving means 10 can be subjected to steps such as adhesive application, drilling, rice attachment, and winding. , While moving the biodegradable mulching film a that is moved by the first rotating unit 110 that rotates in contact with the biodegradable mulching film a that is supplied in an unfolded state. The moving step (S11) by the first rotating part enabling the adhesive attaching process and the punching process to be performed, and the biodegradable mulching film a that has been switched in contact with the first rotating part 110. The second rotating unit that switches the moving direction of the biodegradable mulching film a that is moved by the rotating second rotating unit 120. In step (S12), the moving direction of the biodegradable mulching film moved by the third rotating portion 130 rotating in contact with the biodegradable mulching film a that has been switched in contact with the second rotating portion 120 is switched. However, it can be performed by the moving step (S13) by the third rotating unit so that the rice attachment process can be performed.

  In particular, the moving step (S11) by the first rotating unit 110 is performed by biodegradation in which the outer peripheral surface of the first rotating unit 110 contacts the first rotating unit 110 by the projecting part 111 projecting a certain length and switches the direction. Of course, the mulching film a is separated from the outer peripheral surface of the first rotating part 110 by a certain length at the part where the protruding part 111 comes into contact, and of course, the adhesive application and perforation work can be facilitated by being pulled tight. It is characterized by being able to do. More specifically, as described above, the first protrusion 1111 protruding a fixed length at the center of the protrusion 111 and the protrusion of the first protrusion 1111 spaced apart from each other by a fixed length on the left and right sides of the first protrusion 1111. By forming the second protrusion 1112 that protrudes to a length relatively shorter than the length, the part of the biodegradable mulching film a that contacts and rotates with the first rotating part 110 is in contact with the first protrusion 1111. Of course, the adhesive applying means 20 is not pulled apart from the outer peripheral surface of the first rotating part 110 by a certain length, and the adhesive applying means 20 causes the first protrusion 1111 of the biodegradable mulching film a as shown in FIG. The adhesive can be easily applied to the portion that contacts the surface, and the punching means 30 can be separated from the periphery of the first protrusion 1111 of the biodegradable mulching film a to easily punch the expanded portion. In addition, since the second protrusion 1112 is additionally formed, the biodegradable mulching film a that is separated from the outer peripheral surface of the first rotating unit 110 by a certain length is pulled more naturally. Can be prevented.

  The adhesive application step (S2) is a process of applying an adhesive for attaching rice a3 to the biodegradable mulching film a by the adhesive application means 20, and more specifically, as shown in FIG. An adhesive for attaching rice a3 is applied to the biodegradable mulching film a that rotates in contact with the protruding portion 111 of the rotating portion 110 (more specifically, the first protrusion 1111 protruding so as to protrude most at the protruding portion 111). become. For this purpose, the adhesive application means 20 is formed around the biodegradable mulching film a that is formed at a position corresponding to the first protrusion 1111 of the protruding portion 111 and rotates in close contact with the first rotating portion 110. More specifically, since the adhesive can be applied around the biodegradable mulching film a that rotates in close contact with the first protrusion 1111 that protrudes most on the outer peripheral surface of the first rotating part 110, FIG. As shown in FIG. 4, when the adhesive application process is performed, the adhesive application means 20 is moved to a point separated by a certain length around the first rotating unit 110 to contact the biodegradable mulching film a. When the adhesive application process is not proceeding, the adhesive application means is moved so that the adhesive application means 20 is away from the periphery of the first rotating part 110. Transfer process of the adhesive application means 20 by the part 220 is required.

  The perforating step (S3) is a process of perforating the biodegradable mulching film a by the perforating means 30, and more specifically, as shown in FIG. 3, the first rotation is performed by the protrusion 111 of the first rotating unit 110. A through-hole is formed in the biodegradable mulching film a that is spaced apart from the outer peripheral surface of the portion 110 by a certain length and is expanded (more specifically, spaced apart and inflated between the first protrusion 1111 and the second protrusion 1112 of the protrusion 111). a1 is formed. For this purpose, the punching means 30 is formed at a position corresponding to the space between the first protrusion 1111 and the second protrusion 1112 of the protrusion 111, and tightly between the first protrusion 1111 and the second protrusion 1112. Since the perforated part 310 can be used to easily perforate the pulled biodegradable mulching film a, as shown in FIG. 4, when the perforating process proceeds. Moves the perforation means 30 to a point separated from the periphery of the first rotating part 110 by a certain length so that it can come into contact with the biodegradable mulching film a, and the perforation process for forming the through hole a1 does not proceed. In this case, a process of moving the punching means 30 by the punching means moving part 320 is required to keep the punching part 310 away from the periphery of the first rotating part 110.

  The rice attaching step (S4) is a process of attaching the rice a3 to the part a2 to which the adhesive of the biodegradable mulching film a is applied by the rice attaching means 40, as shown in FIGS. The first drive shaft 421 that rotates by receiving the driving force transmitted by the power means 50 rotates the second drive shaft 422 connected by gear engagement, thereby rotating the first drive shaft 422. The rotating shaft 4231 of the rolling part 423 that is eccentrically connected to one end of the rolling part 423 is rotated while drawing a circle by the rotation of the second drive shaft 422, and the rolling part 423 is also rotated while drawing a circle. At this time, the rice receiver 410 connected to one side of the rolling portion 423 is also periodically rotated while the rice receiver 410 is rotated in the third rotation. The rice a3 that is loaded on the rice tray 410 and unfolded widely is loaded at the moment when the rice tray 410 approaches the third rotating unit 130. The biodegradable mulching film a that rotates in close contact with the adhesive adheres to the part a2 to which the adhesive is attached at regular intervals. At this time, the period of rotation of the rolling part 423, that is, the period of rolling of the rice pad 410 is the interval at which the adhesive is attached to the biodegradable mulching film a rotating in close contact with the third rotating part 130. Preferably, the rice a3 can be efficiently and easily attached to the adhesive application sites a2 formed at regular intervals in the biodegradable mulching film a.

  The winding step (S5) is a final winding process of the biodegradable mulching film a to which the rice a3 is adhered by the winding unit 150, and as described above, the biodegradable mulching film to which the rice a3 is adhered. If the a is simply wound only, the volume of the biodegradable mulching film a wound so as to swell only at the part to which the rice a3 is attached becomes excessively large, and it is difficult to carry and work. In addition, there is a problem that the biodegradable mulching film a itself may be damaged. Therefore, in the present invention, as shown in FIG. 11 and FIG. The hydraulic cylinder 520 is connected to one end of the winding unit 150 so that the hydraulic cylinder 520 moves the one end of the winding unit 150 to the left and right at regular intervals. In the biodegradable mulching film a wound around the winding unit 150, the portion where the rice a3 is attached is not excessively wound only on one side, and is wound so that it can be uniformly distributed to the left and right. In addition, the above-mentioned problems caused by the excessive volume of the biodegradable mulching film a are solved. In particular, one end 532 is connected to the other end of the winding portion 150 around the rotation shaft 531 at the other end of the winding portion 150, and the other side 533 is an inclined chamfered surface 5341 of the rotating cam 534. And the other side 533 of the winding part auxiliary moving part 530 connected to the inclined chamfered surface 5341 of the cam 534 is connected to the rotation of the cam 534 ( At this time, it is preferable that the driving force for rotating the cam 534 is transmitted by the motor unit 510). The winding unit moves around the rotation shaft 531 while periodically moving left and right along a chamfered surface 5341 inclined by the motor unit 510. One side 532 of the auxiliary moving unit 530 and the other end of the winding unit 150 connected to the auxiliary moving unit 530 are moved left and right at regular intervals. Therefore, as described above, the winding unit 150 that moves to the left and right at a constant cycle by the hydraulic cylinder 520 is also operated at a constant cycle by the operation of the winding unit auxiliary moving unit 530 connected to the other end. Since the winding part 150 moves to the left and right, the winding part 150 performs a stable and regular left-right interlocking movement by the operation of the hydraulic cylinders 530 and the winding part auxiliary movement part 530 located on both sides thereof. Thus, the biodegradable mulching film a to which the rice a3 to be wound is attached can be effectively prevented from being excessively swollen or damaged.

  Hereinafter, preferred embodiments of a rice seed sowing decomposition mulching film and a rice cutting method using the same according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 22 is a reference diagram showing the connection and operation relationship between the third rotating part and rice attachment means in FIG. 4, FIG. 23 is a perspective view showing the rice attachment means driving part, and FIG. 24 is a winding part and hydraulic pressure. Connection with cylinder FIG. 25 is a reference diagram showing a coupling relationship between the winding unit and the winding unit auxiliary moving unit, and FIGS. 26 and 27 are reference diagrams showing an operation process of the winding unit auxiliary moving unit. FIG. 28 is a block diagram showing specific contents of the rice seed sowing decomposition mulching film laying step of FIG. 14, and FIG. 29 is a reference diagram showing a process of laying the rice seed sowing decomposition mulching film. 30 is a reference diagram showing a state in which a rice dot sowing decomposition mulching film is laid, FIG. 31 is a reference diagram showing a state in which rice is germinated, and FIG. It is a reference figure showing a state.

  Referring to FIG. 29 to FIG. 31, the rice dot biodegradable mulching film a ′ according to one embodiment of the present invention is made of polylactic acid (which can be replaced with PLA, PCL, PBAT, etc.), talc, aliphatic polyester, lactose. The rice a3 ′ formed by extruding and adhering a plastic resin to a biodegradable compound in which ethyl acetate, methyl methacrylate, powdered milk, biodegradation auxiliary agent, and photodegradation agent are mixed and then extruding is attached. A through hole a1 ′ formed around the rice a3 ′ attached so that it can germinate easily can be included.

  The through-hole a1 ′ is formed around the rice a3 ′ attached to the spotted seed decomposition mulching film according to the present invention at regular intervals, and when the attached rice a3 ′ germinates, the germinated rice a3 ′ The shoots are perforated around the attached rice a3 ′ so that the mulching film can be easily pushed and sprouted on the ground, and the shape is formed to surround the attached rice a3 ′. It is preferable.

  In the present invention, the main technical feature is that the above-mentioned rice spot biodegradable mulching film a ′ is made of a bio-degradable environmental material. However, the biodegradable composition using polylactic acid according to the present invention is made of Lactic acid (PLA can be replaced with PCL, PBAT, etc.), talc agent, aliphatic polyester, lactose, ethyl acetate, methyl methacrylate, powdered milk, biodegradation aid, and photodegradation agent are mixed and processed and then extruded. Molded. Here, polylactic acid (PLA) means a polymer of a low molecular weight compound (monomer) called lactic acid, which is generally hydrolyzed with water to lower its molecular weight and then decomposed by microorganisms. (In addition to the above polylactic acid, it can be replaced with PCL, PBAT, etc.) In particular, the talc agent has the property of improving strength stability, improving fluidity and dispersibility and making it easy to process, and has the effect of reducing material costs. Aliphatic polyester is usually made of a non-biodegradable aromatic polyester molecular structure that is biodegradable by replacing the benzene ring with a hydrocarbon, and has high strength and excellent processability. As an example, polycaprolactone, polybutylene succinate and the like can be used. Ethyl acetate is a processing additive, and is added to improve processability such as cohesion between molecules and surface beauty. Lactose, methyl methacrylate and milk powder promote biodegradation. Biodegradation agents promote biodegradability by contact with microorganisms such as bacteria, sputum, and enzymes under natural conditions, and can be easily used by those skilled in the art. Can be used. The photodecomposing agent concentrates ultraviolet rays to promote oxidation, and a photodecomposing agent containing a photosensitive substance and an ethylene / carbon monoxide polymer can be used. In addition, a plastic resin is mixed with a biodegradable composition using polylactic acid or the like according to the present invention to produce various products. Here, the plastic resin is a base polymer, and the product machine. It is added to ensure proper physical properties (tear strength, tensile strength, etc.). The plastic resin is one of LDPE, LLDPE, HDPE, LMPE, PP, PS, PE, or a mixture of these in a predetermined amount. Here, LDPE is low density polyethylene as an abbreviation for Low Density Polyethylene, HDPE is high density polyethylene as an abbreviation for High Density Polyethylene, LLDPE is linear low density polyethylene as an abbreviation for Linear Low Density Polyethylene, and LMPE is Low Molecular Polyethylene. The abbreviation is low molecular polyethylene, PP is polypropylene as an abbreviation for Polypropylene, PS is polystyrene as an abbreviation for Polystyrene, and PE is polyethylene as an abbreviation for Polyethylene. General HDPE, LDPE, etc. have a molecular weight of 10,000 or more, but since LMPE is formed with a low molecular weight of 2000-2500, it induces a smooth fusion such as CaCo3 when manufacturing the product. Thus, the configuration is polyethylene wax. Hereinafter, the characteristics of the biodegradable mulching film used for the above-described rice dot biodegradable mulching film a 'will be described through experimental examples.

2. Biodegradation degree test (1) Biodegradation degree sample The sample of the above test example 1 was cut into a size of 2 × 2 cm to prepare a biodegradation degree test sample.

(2) Test principle and method Biodegradability test samples are generated during the aerobic composting process based on the Korean Industrial Standard KSM3100-1 “Measurement of aerobic biodegradability and disintegration of plastics under composting conditions” The amount of carbon dioxide is measured to measure the degree of biodegradation of the degradable synthetic resin that is an organic compound. Here, compost is a mixture of plant residues obtained by biodegradation, and other organic matter and organic matter that regulates soil containing specific inorganic components. Composting means an aerobic process for compost generation. The test principle is that the sample and reference material are put into compost and fixed, and then put into a composting container so that composting occurs for a certain period of time. The amount of carbon dioxide generated during the composting process is measured continuously or periodically, and the degree of biodegradation is determined by the ratio between the theoretical maximum carbon dioxide generation amount of the sample and reference material and the actual carbon dioxide generation amount. Come to decide. Here, the theoretical maximum carbon dioxide generation amount (ThCO2) is calculated from the total organic carbon content of the sample or reference material, and the total organic carbon content is determined by the above material component analysis, and the theoretical maximum carbon dioxide generation amount is It is calculated by the following formula.
ThCO2 = MTOT × CTOT × 12/44
MTOT: Total amount of dry solids (g) among the test substances added to the compost at the start of the test
CTOT: ratio of organic carbon contained in the total dry solid content of the test substance (g / g)
44: Molecular weight of carbon dioxide 12: Molecular weight of carbon

The amount of carbon dioxide actually generated is the amount of carbon dioxide generated in a state of being directly connected to each of the above composting containers 1: 1 in a transparent glass tube on which potassium hydroxide and barium chloride mixed aqueous solution is placed. They are collected and measured, and are calculated by the following formula. All these facts are explained in detail in the above Korean industrial standards, so further detailed explanation is omitted.

Ｄｔ：ｔ時間の間の生分解度 The biodegradation degree is calculated based on the following formula.

(CO2) Cumulative amount of carbon dioxide generated from the sample or reference material during t = t time (CO2) b = Cumulative amount of carbon dioxide generated in a container filled only with compost Dt: Raw material during t time Decomposition degree

  All the contents described above are based on the Korean industry standard KSM3100-1.

(3) Characteristic analysis of compost Compost was manufactured at Shomei University and prepared after a composting period of two months. The characteristics analyzed are shown in the following table.

  Here, the total dry solid content is the amount of solid content obtained after drying so that the compost becomes a constant weight at 105 ° C., and the volatile solid content was extracted from the above total dry solid content after incineration at 550 ° C. This is the amount of solids obtained later. Volatile solid content is an indicator of organic content.

  As seen from the “Remarks” column in the above table, the above compost has moisture content, acidity, solid content, and C / N ratio all within the standard range. Judged to meet the requirements.

(4) Measurement of biodegradability of Test Example 1 and standard substance The three samples of Test Example 1 described above were fixed together with the above compost and placed in three composting containers, and observed for 59 days. Further, TLC grade cellulose of 20 μm or less was used as a standard substance, which was fixed together with the above compost and placed in a composting container, and observed for 59 days. And only the compost which does not put a test piece and a standard substance was put in the composting container, and it observed for 59 days. For each case, the amount of carbon dioxide generated is measured every day, and the average value (CO2) Bmean of the amount of carbon dioxide generated in the three composting containers is calculated based on the above formula. An average value (Dt) of the degree of decomposition was also calculated, and the result was represented by the following graph.

<グラフ１ 二酸化炭素発生量>

<Graph 1 Carbon Dioxide Generation>

<グラフ２生分解度>

<Graph 2 degree of biodegradation>

  According to the graph 1 above, it can be confirmed that the amount of carbon dioxide generated in the compost in which Test Example 1 is fixed is larger than that of the other compost, and the amount of carbon dioxide generated gradually increases as time passes. Then, after a certain period of time, it was found that the biodegradation was actively progressing with a rapid increase. Further, according to Graph 2, Test Example 1 has a low carbon dioxide generation amount and biodegradability at the beginning compared with cellulose which is a standard substance, but increases rapidly as time passes like cellulose. Therefore, it can be seen that biodegradation is in progress in a natural state like cellulose. And, when comparing the biodegradation degree with respect to the standard substance and the specimen at 59 days, it is as shown in the following <Table 2>.

  As can be confirmed from the above table, in Test Example 1, the biodegradation degree increased rapidly after a certain period of time, and a biodegradation degree of 52.2% was observed at 59 days. It reaches 71.7% of cellulose.

Experiment 2: Biodegradation measurement by MITImethod (1) Experimental method After collecting and mixing from more than 10 places of sludge, compost, and soil, culturing for 10 days or more while supplying synthetic medium once a day, This was used as an inoculum microorganism. Then, the amount of oxygen consumed in the process in which the inoculated microorganism decomposes the polymer was measured using a respirometer. In this experiment, the same cellulose as that used in Experiment 1 was used as the standard substance.

(2) Experimental results The oxygen consumption (mg / L) measured with a respirometer is summarized in the following table.

  According to the above table, it was confirmed that Test Examples 2 to 4 had a lower oxygen consumption than the reference material, but were significantly higher than Comparative Examples 2 to 4.

For reference, before explaining the step of providing the rolled-up rice spot sowing decomposition mulching film a ′ (S1 ′), the provision of the rolled-up rice spot sowing decomposition mulching film a ′ will be described. The apparatus used will be described first.

  As shown in FIGS. 16 to 27, the apparatus used to provide the above-rolled rice-spotted biodegradable mulching film a ′ is unrolled for perforating and attaching rice to the biodegradable mulching film a ′.

A handle 150 'can be included.

  The first rotating unit 110 ′ is configured to switch the moving direction of the biodegradable mulching film a ′ that moves while rotating in contact with the biodegradable mulching film a ′ supplied to the biodegradable mulching film manufacturing apparatus according to the present invention. In order to be able to smoothly change the moving direction by abutting with the easy rotation and biodegradable mulching film a ′, it can be formed into a cylindrical rod shape, one end of which will be described later. The power unit 50 'is connected to rotate using the power provided by the power unit 50'. Particularly in the present invention, the first rotating part 110 ′ is not limited to simply switching the moving direction of the biodegradable mulching film a ′ that moves while rotating in contact with the biodegradable mulching film a ′. The adhesive application means 20 ′ and the perforation means 30 ′ perform a function of assisting the adhesive application operation and the perforation operation to be performed smoothly. For this purpose, the first rotating part 110 ′ is provided on the outer peripheral surface. The portion of the biodegradable mulching film a ′ that contacts the first rotating part 110 ′ including the protruding part 111 ′ that protrudes a certain length in contact with the first rotating part 110 ′ and that changes its direction is in contact with the first rotating part 110. In addition to being separated from the outer peripheral surface of the fixed length by a certain length, it is possible to easily perform adhesive application and perforation work at the above-mentioned site by being pulled tightly. To.

  The protrusion 111 ′ is a portion formed to protrude from the outer peripheral surface of the first rotating portion 110 ′ by a certain length. More specifically, the protrusion 111 ′ protrudes from the center of the protrusion 111 ′ by a certain length. A protrusion 1111 ′ and a second protrusion 1112 ′ that protrudes from the left and right sides of the first protrusion 1111 ′ by a predetermined length and protrudes relatively shorter than the protrusion length of the first protrusion 1111 ′; it can. The first protrusion 1111 ′ is a portion that protrudes from the outer peripheral surface of the first rotating part 110 ′, more specifically, at a central part of the protruding part 111 ′. Of course, the part of the biodegradable mulching film a ′ that contacts and rotates with the first rotating part 110 ′ is separated from the outer peripheral surface of the first rotating part 110 ′ by a certain length. As shown in FIG. 18, the adhesive applying means 20 ′, which will be described later, can easily apply the adhesive to the portion of the biodegradable mulching film a ′ that contacts the first protrusion 1111 ′ by being pulled. In addition, as shown in FIG. 18, the perforating means 30 ′ described later is pulled apart from the outer peripheral surface of the first rotating part 110 ′ by a certain length as well as the biodegradable mulching film a ′. It will be able to pierce the easy through-hole a1 'to the site. For reference, when the biodegradable mulching film a 'is in close contact with the outer peripheral surface of the first rotating part 110', there is a problem that not only the drilling operation can be smoothly performed, but also the manufacturing cost is increased. The protruding shape of the first protrusion 1111 ′ is preferably chamfered so that both protruding end portions are inclined or formed in a round shape. This is to prevent damage to the mulching film a ′. In addition, the second protrusion 1112 ′ is a portion that is spaced apart from the first protrusion 1111 ′ by a predetermined length and protrudes to a length relatively shorter than the protrusion length of the first protrusion 1111 ′. The second protrusion 1112 ′ is additionally formed, so that the biodegradable mulching film a ′ separated from the outer peripheral surface of the first rotating part 110 ′ by a certain length is pulled more naturally. It becomes possible to prevent being damaged. The protruding shape of the second protrusion 1112 'is preferably chamfered so that both protruding ends are inclined or formed in a round shape.

  The second rotating part 120 ′ is in contact with the first rotating part 110 ′ and changes the moving direction of the biodegradable mulching film a ′ that moves while rotating in contact with the biodegradable mulching film a ′ that has been switched in direction. Further, the adhesive application site a2 of the biodegradable mulching film a ′, which is configured to be switched and is normally switched so as to move upward while rotating in contact with the first rotating part 110 ′. The second rotating part 120 ′ is used for the rice attachment process for attaching the rice a3 to “and for the purpose of switching the moving direction of the biodegradable mulching film a ′ to the downward moving direction. The moving direction is switched while rotating in contact with a ′. In addition, the biodegradable mulching film a ′ is pulled tightly so that the second rotating part 120 ′ can smoothly perform the adhesive application process and the perforating process centered on the first rotating part 110 ′. It also performs an auxiliary role. For reference, the biodegradable mulching film a ′ is unfolded before the rice attachment process is performed on the biodegradable mulching film a ′ whose direction is changed while rotating in contact with the second rotating part 120 ′. Are arranged again and the biodegradable mulching film a ′ is pulled tightly, an additional fourth rotating part 140 ′ is interposed between the second rotating part 120 ′ and a third rotating part 130 ′ described later. Can further be included.

  The third rotating part 130 'is in contact with the second rotating part 120' and changes the direction of movement of the biodegradable mulching film a 'that moves while rotating in contact with the biodegradable mulching film a' whose direction has been switched. The third rotating part 130 ′ is configured to be switched again so that the step of attaching the rice a3 ′ to the part a2 ′ to which the adhesive of the biodegradable mulching film a ′ is applied can be performed. The direction of the biodegradable mulching film a ′ that moves while rotating in contact with the biodegradable mulching film a ′ is switched.

  The winding unit 150 ′ is configured to finally wind up the biodegradable mulching film a ′ to which the rice a3 ′ is attached after passing through the third rotating unit 130 ′, and the winding unit 150 ′ performs final winding. If the attached biodegradable mulching film a 'is spread and applied to the rice field, the rice can be grown by the rice seeding method without raising seedlings or rice planting work. In addition, the winding unit 150 ′ is not limited to simply winding the biodegradable mulching film a ′ to which the rice a3 ′ is attached while performing only rotation. As shown in FIGS. The rice a3 ′ is prevented from being excessively swollen or damaged while being rolled up, as will be described later. This will be described in detail with respect to the hydraulic cylinder 520 ′ and the winding unit auxiliary moving unit 530 ′.

  The adhesive application means 20 ′ is configured to apply an adhesive for attaching rice to the biodegradable mulching film a ′ moved by the moving means 10 ′. More specifically, as shown in FIG.

The structure is such that an adhesive can be applied only to the decomposed mulching film a ′, and the end of the adhesive application part 210 ′ is coated with an adhesive so that the adhesive can be applied easily. A connecting pipe branched from a container in which the adhesive is stored is connected to the adhesive application unit 210 ′ so that the adhesive can be supplied. For reference, the adhesive application unit 210 ′ includes a separate opening / closing means that can prevent the adhesive from being ejected through the adhesive application unit 210 ′ when the adhesive application process is not performed due to the necessity of work. .

  As shown in FIGS. 18 and 19, the adhesive application unit moving unit 220 ′ can move the adhesive application unit 20 ′ so as to approach or move away from the first rotating unit 110 ′. In the present invention, the adhesive applying means 20 ′ is rotated around the biodegradable mulching film a ′ rotating in close contact with the first rotating part 110 ′ around the first rotating part 110 ′. Since the adhesive can be applied to the periphery of the biodegradable mulching film a ′ that protrudes most on the outer peripheral surface of the first rotating part 110 ′, the adhesive applying means 20 ′ is used as the first rotating part. As shown in FIG. 18 by moving to a point separated by a certain length around 110 ′ so as to be able to come into contact with the biodegradable mulching film a ′, and when the adhesive application process does not proceed, As shown in 19, it is necessary to configure such that 'the adhesive applying means moving portion 220 so as away from the periphery of' the first rotating portion 110. A configuration such as an electronically controlled hydraulic cylinder can be used for the adhesive application means moving unit 220 '.

  The perforating means 30 ′ is configured to perforate a through-hole a1 ′ in the biodegradable mulching film a ′ moved by the moving means 10 ′. More specifically, as shown in FIG. 110 ′ protruding portion 111 ′ is spaced apart from the outer peripheral surface of the first rotating portion 110 ′ by a certain length to expand (more specifically, between the first protrusion 1111 ′ and the second protrusion 1112 ′ of the protruding portion 111 ′). A through-hole a1 'is formed in the biodegradable mulching film a' which is separated and expanded by (1). For this purpose, the punching means 30 ′ is formed at a position corresponding to the space between the first protrusion 1111 ′ and the second protrusion 1112 ′ of the protrusion 111 ′, and the first protrusion 1111 ′ and the second protrusion 1112 are formed. A perforating part 310 ′ for enabling easy perforation to be made in a portion of the biodegradable mulching film a ′ that is tightly pulled between and a perforating means 30 ′ on the first rotating part 110 ′ side A piercing means moving part 320 ′ that can be moved may be included. For reference, since the adhesive applying means 20 ′ and the punching means 30 ′ all perform the work around the first rotating part 110 ′, the adhesive applying means 20 ′ and the punching means 30 ′ are configured as described above. It is preferable to be positioned symmetrically about the rotating part 110 ′.

  The perforated part 310 ′ is formed at a position corresponding to the space between the first protrusion 1111 ′ and the second protrusion 1112 ′ of the protrusion 111 ′, and is formed between the first protrusion 1111 ′ and the second protrusion 1112 ′. It is configured to allow easy perforation to the portion of the biodegradable mulching film a ′ that has been pulled tightly so that it can be easily perforated to the portion of the biodegradable mulching film a ′ that has been tightly pulled. Therefore, the end of the perforated part 310 'can be easily perforated in a wider range than heat cutting means such as a heat ray (that is, if the heat is brought into contact with a tightly pulled part, cutting is performed. The perforated part 310 ′ is connected to a power source part so that electricity can be supplied to heat generating means such as a heat ray. For reference, when the drilling process is not performed on the punching unit 310 ′ due to the necessity of work, a separate power source is used to prevent a safety accident or the like from occurring due to continuous operation of heat generating means such as a hot wire. A blocking means can be included.

  As shown in FIGS. 18 and 19, the punching means moving part 320 ′ is configured to move the punching means 30 ′ so as to approach or move away from the first rotating part 110 ′. In the present invention, the perforating means 30 ′ is rotated around the first rotating part 110 ′ around the biodegradable mulching film a ′ rotating in close contact with the first rotating part 110 ′, more specifically, the first protrusion 1111. The biodegradable mulching film a ′, which is expanded by projecting on the outer peripheral surface of the first rotating part 110 ′, is formed between “and the second protrusion 1112 ′” so that a through hole a1 ′ can be formed. Therefore, during the perforating step, as shown in FIG. 18, the perforating means 30 ′ can be moved to a point separated by a certain length around the first rotating part 110 ′ to be brought into contact with the biodegradable mulching film a ′. If the drilling step for forming the through hole a1 ′ is not performed, the punching means moving unit 320 ′ is arranged so as to be separated from the periphery of the first rotating unit 110 ′ as shown in FIG. Such a configuration is required. The punching means moving portion 320 'can utilize a configuration such as an electronically controlled hydraulic cylinder, similar to the adhesive application means moving portion 220'.

  The rice attachment means 40 ′ is configured to attach the rice a3 ′ to the part a2 ′ to which the adhesive of the biodegradable mulching film a ′ moved by the movement means 10 ′ is applied, and the third rotating part 130. Rice a3 'is attached to the adhesive application part a2' of the biodegradable mulching film a 'rotating in close contact with the rice and the rice a3 is efficiently applied to the part a2' where the adhesive is periodically applied at regular intervals. The rice attachment perpetual 40 'accommodates rice a3' and allows the rice a3 'accommodated widely to be spread and scattered, and the rice receptacle The rice a3 ′ is efficiently and easily attached to the adhesive application sites a2 ′ at regular intervals of the biodegradable mulching film a ′ that is rotated by periodically rolling 410 ′ and contacts the third rotating part 130 ′ to switch the direction. Can May include a rice attachment means driving unit 420 'that way.

  The rice receiver 410 ′ is configured to receive the rice a3 ′ and allow the accommodated rice a3 ′ to be unfolded and scattered widely, and to be moved by the moving means 10 ′ while being unfolded widely. In order to attach the rice a3 ′ to the adhesive application site a2 ′ of the decomposed mulching film a ′, the rice receiver 410 ′ in which the rice a3 ′ is accommodated can be spread and scattered in the rice a3 ′ accommodated therein. It is preferably formed in a form that is long in the long direction and has a certain width.

  As shown in FIGS. 21 and 22, the rice attachment means driving unit 420 ′ is a biodegradable mulching film a that periodically rolls the rice pad 410 ′ and contacts the third rotating unit 130 ′ to switch the direction. In this configuration, the rice a3 ′ can be efficiently and easily attached to the adhesive application site a2 ′ formed at a constant interval, and the rice attachment means driving unit 420 ′ is described later. From the first drive shaft 421 ′ rotated by the power provided from the power means 50 ′, the second drive shaft 422 ′ rotated in conjunction with the first drive shaft 421 ′, and the axial center of the second drive shaft 422 ′. When the second drive shaft 422 ′ rotates, the rolling portion 423 ′ that periodically rolls the rice receiver 410 ′ on which the rice a3 ′ is loaded can be included.

In order to compensate for the fact that it is difficult to stably drive a rolling part 423 ′, which will be described later, by using only the first drive shaft 421 ′, the second drive shaft 422 ′ is formed in two or more plural pieces. The rolling unit 423 ′, which will be described later, can be stably driven by the two drive shafts 422 ′.

  The rolling part 423 ′ is decentered from the shaft center of the second drive shaft 422 ′, so that the rice receiver 410 ′ loaded with rice a3 ′ is rotated as the second drive shaft 422 ′ rotates. As shown in FIG. 23, one side of the rolling part 423 ′ is connected to the rice pad 410 ′, and the rotating shaft 4231 ′ of the rolling part 423 ′ is connected to the second part. When the second drive shaft 422 ′ rotates by being decentered and coupled off the axis of the drive shaft 422 ′, the rotation decentered and decoupled from the axis of the second drive shaft 422 ′. The shaft 4231 ′ rotates while drawing a circle, and thereby the rolling portion 423 ′ also rotates while drawing a circle. At this time, the rolling portion 4 As shown in FIGS. 21 and 22, while the rice receiver 410 ′ connected to one side of 3 ′ is also periodically rolled, the rice receiver 410 ′ periodically approaches the third rotating part 130 ′.
