Description

  The present invention relates to a straw compression binding apparatus that binds after compressing a straw. In particular, the present invention relates to an apparatus for bundling after compressing straw into a rectangular parallelepiped.

Straw is used as agricultural material, such as bedding straw and feed for livestock, or horticultural coating materials and compost materials. Because straw is cheap and bulky, it is mainly used by farmers for their own use or in the vicinity, and is not suitable for transporting far away. The straw is generally stored as it is in a barn, or compressed into a large roll of rolled balls and stored.
Recently, there has been a need to supply straw from a distance under the influence of large-scale fattening and foot-and-mouth disease. If it is bulky, the transportation cost is high and expensive. In addition, there are problems that a large roll is too large to be handled and a load such as a truck has a gap and is inefficient and poor in stability.
As a conventional example, there has been proposed a straw material compression molding apparatus configured to form a cylindrical roll-shaped product while compressing the straw material with a plurality of press rolls (see Patent Document 1). Since the straw material compressed product forming apparatus described in Patent Document 1 is formed into a cylindrical shape while compressing the straw material, when the molded product of the straw material compressed into the cylindrical shape is stored or transported, the molded product A gap is formed between them, so that it cannot be efficiently stored or transported in a small space.

  On the other hand, in a device for packing naturally dried grass that has been cut and harvested in a field, etc. A packaging grass collection wagon having a configuration in which a collection wagon to collect is installed has been proposed (see Patent Document 2). In the packed grass collection wagon described in Patent Document 2, when compressing naturally dried grass into a rectangular parallelepiped, it is only compressed in one direction in the conveying direction. There is a problem that it is easy to collapse and cannot be compressed uniformly.

Since a predetermined amount of straw is compressed in the vertical direction by the primary compression means and then compressed in the horizontal direction by the secondary compression means to form a rectangular parallelepiped compression straw, the straw is evenly distributed in both the vertical direction and the horizontal direction. It can be compressed. The compressed straw after being compressed into a rectangular parallelepiped shape is bound by binding means along the compression direction (for example, the longitudinal direction) and bound, and then discharged by the discharge means. It is difficult to collapse and can be efficiently stored and transported.
Furthermore, since it is a secondary compression means that compresses a plurality of predetermined amount of straw compressed by the primary compression means into a plurality of times and compresses it into a rectangular parallelepiped compression straw, a predetermined amount of compressed in the vertical direction The straw can be compressed into a rectangular parallelepiped-shaped compressed straw by dividing it into a plurality of times, and the compressed straw can be compressed more uniformly in the lateral direction.
After the straw is weighed by a weighing unit provided adjacent to the primary compression means, the straw is transferred to a predetermined position where the straw is compressed by the primary compression means. The straw carried in by this transport means is transported to a state where the width direction is compressed and regulated by the width to be packed. Since the straw to be compressed by the primary compression means can be weighed before being transferred to the primary compression means, the straw can be more accurately weighed. Compared with the case where the weighing means is provided in the primary compression means, the surplus power when the straw is compressed by the primary compression means is less likely to reach the weighing means, so that the weighing means can be prevented from being damaged.

The straw can be evenly compressed in each of the vertical direction and the horizontal direction, and the compressed compressed straw can be hardly deformed. And since the string is tied in the compression direction in the lateral direction, the binding string is not easily detached from the packing. Handling and handling of this rectangular parallelepiped compressed straw are facilitated effectively.
Furthermore, by providing a concave portion for avoiding contact at the time of rotation of the needle along the vertical direction in the lateral pushing plate, the needle of the bundling means is rotated along the vertical direction, and the secondary compression means When the strap is compressed along the longitudinal direction with the compressed straw compressed in a rectangular parallelepiped shape, the needle enters the concave portion of the lateral pushing plate, so that the contact with the lateral pushing plate when the needle rotates can be prevented.

In the present invention, a predetermined amount of straw, in particular rice straw, is compressed in the vertical direction by primary compression means, and then compressed in the horizontal direction by secondary compression means to form a rectangular parallelepiped compressed rice straw. Since each is compressed, rice straw can be compressed evenly. In addition, since the compressed packing rice straw compressed in a rectangular parallelepiped shape is tied and tied along the longitudinal direction, the string does not come off, and the compressed rice straw does not easily lose its shape. The compressed rice straw can be stored and transported efficiently. In particular, in the secondary compression means, a plurality of predetermined amounts of rice straw compressed by the primary compression means were compressed in multiple times to form a rectangular parallelepiped compressed rice straw, which was compressed vertically. A predetermined amount of rice straw is compressed into a plurality of times and combined into a rectangular parallelepiped compressed rice straw, and the compressed rice straw can be compressed more evenly in the lateral direction.
Furthermore, a means for measuring the straw sent to the primary compression means before the primary compression is provided. For this reason, the amount of rice straw when compressed by the primary compression means can be made uniform, and the compression by the secondary compression means in the lateral direction of the compressed rice straw can be made more uniform. In particular, by weighing a predetermined amount of straw in a weighing unit provided adjacent to the primary compression means, and transferring the predetermined amount of straw to a predetermined position where the straw is compressed by the primary compression means, Since the straw to be compressed by the primary compression means can be weighed at the stage before being transferred to the primary compression means, the predetermined amount of straw can be more accurately measured, and when the weighing means is provided in the primary compression means. In comparison, the surplus force when the straw is compressed by the primary compression means is less likely to reach the weighing means, so that the weighing means can be prevented from being damaged.
Also, by opening and closing the shutter of the discharge means, the compressed rice straw compressed by the secondary compression means and bound by the binding means is efficiently pushed out and discharged with a simple configuration. A recess for avoiding contact when the needle of the bundling means is rotated is provided in the lateral pushing plate of the secondary compression means, and the needle of this bundling means is rotated along the vertical direction, and the secondary compression means It was set as the structure which can be tied along the longitudinal direction to the compression straw compressed into the rectangular parallelepiped shape. Since this needle enters into the concave portion of the lateral pushing plate, it is possible to prevent contact with the lateral pushing plate when the needle is rotated.
In addition, slits for repairing the string and needle are formed on the upper and lower surfaces of the chamber in which the straw is formed into a rectangular parallelepiped by lateral compression so that the string is easily hooked in the longitudinal direction.
Furthermore, by providing a blade-like portion at each of the edge of the secondary compression region when the straw is compressed in the transverse direction in the secondary compression portion of the secondary compression means and the edge of the lateral pushing plate, When compressing by the secondary compression means, the straw can be compressed in the lateral direction while cutting the straw protruding from the secondary compression region, so that the compression by the secondary compression means can be ensured and the secondary compression can be performed. It is possible to prevent damage to the secondary compression part and the lateral pushing plate of the means.

FIG. 1B is a schematic plan view of the apparatus, and FIG. 1C is a schematic side view.
The straw W is thrown into the measuring means 11 provided with a hopper etc., and a predetermined amount is measured. Since the straw is bulky, the amount obtained by dividing the bundling straw D is treated as one batch. The weighed straw is sent to the primary compression means 2. Since the width direction is determined at this stage, forming in the width direction is performed. The primary compression means 2 is compressed in the vertical direction by the pushing plate 22 from above, and the height direction is molded to a predetermined height. In the figure, a shutter 61 that opens and closes as a partition means is provided because the measuring unit and the primary compression means communicate with each other.

Next, operation | movement of the straw compression binding apparatus 1 of this one Example is demonstrated mainly with reference to FIG.
<Pretreatment process>
When the straw W that has been dried after harvesting rice plants such as rice, wheat, and barley from the paddy field or field and threshing is made into a predetermined amount of bundles or rolls, the predetermined amount of straw W is bundled In addition to cutting the bundled straws etc. that are made into pieces, etc., if necessary, each straw W can be cut to a predetermined length from the viewpoint of making the density and weight of the compressed straw C that is the product uniform. Preprocessing is performed by loosening or the like (step 1).

<Import process>
The preprocessed straw W is continuously transported by the input conveyor 17 and is transported and input into the measuring box 12 of the measuring machine 11. At this time, the weight of the straw W introduced into the measuring box 12 is measured by each measuring load cell 13 attached to the bottom portion 12d of the measuring box 12, and is put into the measuring box 12. When the straw W reaches a predetermined amount, for example, 5 kg, the control device (not shown) stops the input of the straw W by the input conveyor 17 (step 2).

<Transfer process>
When a predetermined amount of straw W is introduced into the weighing box 12 of the weighing machine 11, the lateral feed cylinder 15 is driven, and the opening 21b of the primary compression box 21 is closed from the position where the one side surface 12a of the weighing box 11 is closed. The transfer plate 14 is moved to a position where it is moved, and the transfer plate 14 transfers the straw W in the weighing box 12 to the primary compression region 21d of the primary compression box 21 while being compressed to some extent (step 3). . During the transfer, the shutter 61 is opened, and the shutter 61 is closed in a state where the transfer plate 14 reaches the movement end side surface 12b.

<Primary compression process>
When a predetermined amount of straw W is transferred to the primary compression area 21d of the primary compression box 21 of the primary compressor 2, first, the motor 25d of the pushing unit 25 is driven, and the cradle 25e is moved downward with respect to the vertical rack 25b. The cradle 25e moves downward until the vertical pushing plate 22 reaches the upper end position of the primary compression region 21d of the primary compression box 21.
When the vertical pushing plate 22 is lowered to the upper end position of the primary compression region 21d, the vertical pushing cylinder 25a is driven, and the vertical pushing plate 22 is moved to the primary compression region 21 by the vertical pushing cylinder 25a. A predetermined amount of straw fed into the primary compression region 21d is pushed from above by the vertical pushing plate 22 and is primarily compressed at a pressure of, for example, 4000 kg to be primary compressed straw. (Step 4).

<Secondary compression process>
The primary compressed straw subjected to the primary compression is discharged from the primary compression region 21d by the lateral pushing plate 32 by the driving of the lateral pushing cylinder 32a and is sent to the secondary compression region 31a of the secondary compressor 3. At this time, the movable blade 32d provided on the other side surface 32b of the lateral pushing plate 32 and the fixed blade attached to the upstream edge portion of the secondary compression region 31a of the secondary compression box 31 of the secondary compressor 3. At 31c, the side pushing plate 32 sends the straw W from the primary compression region 31d to the secondary compression region 31a while cutting the straw W jumping out from the upstream side of the secondary compression region 31a.
Furthermore, each binding string T attached between the needle 41 and the bobbin 42 of the binding machine 4 is inserted into the secondary compression region 31a along the vertical direction, and these binding strings T are connected to the primary compression straw and the shutter 51. Located between. Here, when no other primary compression straw exists in the secondary compression region 31 a of the secondary compression box 31, this primary compression straw is used as the first primary compression straw, and the side compressor of the secondary compressor 3 is pressed. The plate 32 is pushed downstream of the secondary compression region 31a, and is secondarily compressed in the lateral direction between the lateral pushing plate 32 and the shutter 51 (step 5).
Here, after the first primary compression straw is secondarily compressed, the primary compression straw sent to the secondary compression region 31a after the first primary compression straw is used as the second primary compression straw. Step 4 is repeated, and the first primary compression straw is secondarily compressed in the lateral direction together with the second primary compression straw.
Furthermore, after the second primary compression straw is secondarily compressed, the primary compression straw sent to the secondary compression region 31a after the second primary compression straw is further used as the third primary compression straw. Step 4 is repeated, and the second primary compression straw and the third primary compression straw together with the third primary compression straw are secondarily compressed in the lateral direction so as to have a length of, for example, 600 mm. For example, a rectangular parallelepiped compressed straw C having a length of 600 mm, a width of 400 mm, and a height of 300 mm and a weight of 15 kg in total is manufactured.

<Bundling process>
A total of 15 kg of compressed straw produced by repeating the secondary compression process of step 4 three times drives the drive motor 46 of the binding machine 4 in a state where the pushing of the lateral pushing plate 32 by the lateral pushing cylinder 32a is released. Then, the needle swing ring 44 is rotated upward, the needle swing bracket 43 is driven to reverse by about 50 °, and the needles 41 are rotated upward, so that the binding position shown in FIG. 9 is changed from the standby position shown in FIG. Each binding string is rotated by rotating the tip end side of each needle 41 upward after tying a total of two binding strings T along the longitudinal direction of the compressed straw. After the front end of T is tied, it is cut with a cutter, and this compressed straw is bound into two strips by a total of two binding strings T.
At this time, each needle 41 passes through the lower slit 31 d of the secondary compression box 31 and is inserted into the secondary compression region 31 a of the secondary compression box 31, and the other side surface of the lateral pushing plate 32. It enters into each avoidance recessed part 32c provided in 32b, and a contact with this horizontal pushing board 32 is avoided. Thereafter, each string return device 48 moves each needle 41 from the binding position shown in FIG. 9 to the standby position shown in FIG. 8 while applying an appropriate tension to each binding string T. (Step 6). The tying string is guided and fixed to the surface of the straw as the straw is compressed. Since the string is forcibly pulled out, a string passing slit is not necessarily required, but it is preferable to provide a string passing slit on the upper surface of the secondary compression box 31 for maintenance and confirmation. .

<Discharge process>
The bundling straw D that is bound in two strips by the two binding strings T is opened by the lateral pushing plate 32 by the lateral pushing cylinder 32a of the secondary compressor 3 after the shutter 51 is opened by the shutter hydraulic cylinder 52. Is discharged to the downstream side, pushed out from the opening 31f on the downstream side of the secondary compression box 31 and discharged, and the next process is performed at the discharge conveyor 53 installed on the downstream side of the opening 31f. It will be sent to. Further, after the binding straw D is discharged from the opening 31f, the shutter 51 is closed by the shutter hydraulic cylinder 52, and the opening 31f is closed (step 7).

<Continuous process>
After the discharge process of step 7 is completed, the above steps 1 to 7 are sequentially repeated to manufacture a plurality of bundling straws D continuously.

From the above, the straw compression bundling apparatus 1 according to the present embodiment compresses a predetermined amount of straw W in the primary compression box 21 in the primary compressor 2 in the vertical direction, and then the secondary compression box of the secondary compressor 3. In order to compress in a horizontal direction in the secondary compression box 31 to form a rectangular parallelepiped compressed straw C, a predetermined amount of straw W can be evenly compressed in each of the vertical direction and the horizontal direction, The compressed straw C compressed in the shape of a rectangular parallelepiped is bound by binding the two binding strings T in the circumferential direction in the binding machine 4 along the circumferential direction, and then extruded by the discharging machine 5 to be discharged. Therefore, the compressed compressed straw C can be made difficult to lose its shape, and can be efficiently stored and transported. Therefore, since it is a rectangular-shaped bundling straw D that is not easily deformed, it can be packed in a truck bed or the like without gaps and can be transported over a long distance, thereby reducing transportation costs. In particular, if a contagious disease such as foot-and-mouth disease spreads in livestock in a specific area, it is necessary to transport straw used as livestock feed or bedding straw from a distant area where the contagious disease does not spread. If it is the bundling straw D manufactured using the straw compression bundling apparatus 1 of this invention, uniform quality straw can be efficiently transported over a long distance without losing its shape.
Further, a plurality of, for example, three primary compressed straws compressed by the primary compressor 2 are secondarily compressed by the secondary compressor 3 three times, and the three primary compressed straws are laterally compressed. Since the compressed straw C in the shape of a rectangular parallelepiped is compressed side by side, the primary compressed straw compressed in the vertical direction can be divided into a plurality of times and compressed in the horizontal direction to form a compressed straw C in the shape of a rectangular parallelepiped. The straw can be compressed more uniformly in the lateral direction, and the compressed straw C can be more easily deformed. Further, since the compressed straw C is bound by the two binding strings T along the secondary compression direction of the compressed straw C after the secondary compression, the compressed straw C is most deformed. It is possible to efficiently prevent the deformation of the mold in the secondary compression direction, and the length, that is, the size of the compressed straw C in the secondary compression direction can be defined reliably.

Then, by measuring the weight of the straw W sent to the primary compression box 21 by the weighing machine 11 installed adjacent to the primary compression box 21 of the primary compressor 2, the primary compression box 21 is primary. The weight of the straw W at the time of the primary compression in the compression region 21d can be made uniform, and the secondary compression in the secondary direction in the secondary compression region 31a of the secondary compressor 3 of the primary compression straw after the primary compression is performed. Since it can be made more uniform, the weight of the compressed straw C after the secondary compression can be made uniform. In particular, since the straw W is weighed by the weighing box 12 of the weighing machine 11 and then the straw W is pushed and transferred by the transfer plate 14 to the primary compression region 21d of the primary compression box 21, the primary compression is performed. Since the straw W to be compressed by the primary compressor 2 can be weighed before being transferred to the primary compression box 21 of the machine 2, the straw W can be weighed more accurately and the primary compressor 2 can be weighed. Compared with the case where a machine is provided, the surplus power when the straw W is compressed by the primary compressor 2 can be less likely to reach the weighing machine, so that the weighing machine 11 can be prevented from being damaged.
Further, in the primary compression in the primary compression region 21d of the primary compression box 21 of the primary compressor 2, first, as a first stage drive, the motor 25d of the pushing unit 25 is driven to support the vertical rack 25b with the cradle 25e. Is moved downward to lower the cradle 25e until the vertical pushing plate 22 reaches the upper end position of the primary compression area 21d of the primary compression box 21, and then the vertical pushing cylinder 25a is driven as a second stage drive. Then, the vertical pushing plate 22 is pushed into the primary compression area 21d of the primary compression box 21 by the vertical pushing cylinder 25a, and a predetermined amount of thrown straw thrown into the primary compression area 21d by the vertical pushing plate 22 is primary. By adopting a total of two-stage drive mechanism that compresses the primary compressed straw, for example, the vertical pushing plate 22 of the weighing box 12 is made only by the vertical pushing cylinder 25a. Since the stroke of the vertical pushing cylinder 25a can be shortened compared with the case where the side surface 12a is moved from the closed position to the position where the primary compression is completed, the configuration of the primary compressor 2 can be downsized in the vertical direction. In addition, the manufacturing cost of the primary compressor 2 can be reduced.

Then, by providing a pair of avoiding concave portions 32c having a concave cross section along the vertical direction on the other side surface 32b of the horizontal pressing plate 32 of the secondary compressor 3, the horizontal pressing plate 32 of the secondary compressor 3 compresses the straw. In the state after pushing in C, each needle 41 of the binding machine 4 is rotated in the vertical direction, and the compressed straw C secondarily compressed by the secondary compressor 3 is tied along the longitudinal direction. Since these needles 41 enter the avoiding recess 32c of the lateral pushing plate 32, contact between these needles 41 and the lateral pushing plate 32 is avoided, and these needles 41 can be rotated in the vertical direction. It is possible to reliably prevent contact with the lateral pushing plate 32 when the 41 is rotated.
Further, a fixed blade 31 c is provided at the upstream edge of the secondary compression region 31 a of the secondary compression box 31 of the secondary compressor 3, and the upper side of the other side surface 32 b of the lateral pushing plate 32 of the secondary compressor 3. Since the movable blade 32d is provided on each of the edge except for the avoidance recesses 32c and the upper edge of the bottom surface of each avoidance recess 32c, the lateral pushing plate 32 of the secondary compressor 3 is subjected to secondary compression. When the primary compressed straw is secondarily compressed by moving laterally in the box 31, the straw W protruding from the upstream side of the secondary compression region 31a of the secondary compression box 31 is fixed to the fixed blade 31c and the movable blade 32d. The primary compressed straw can be secondarily compressed in the transverse direction while cutting at. Accordingly, the lateral pushing plate 32 can be prevented from being clogged due to the straw W entering the gap between the lateral pushing plate 32 and the secondary compression box 31 of the secondary compressor 3. The secondary compression in the 32 and the secondary compression box 31 can be more reliably performed, and the damage of the lateral pushing plate 32 and the secondary compression box 31 can be more reliably prevented.
Further, the shutter 51 provided in the discharge machine 5 is used to push out the bundled straw D, which is secondarily compressed by the secondary compressor 3 and bound by the bundler 4, from the shutter 51 and discharged. As a result, the bundling straw D can be pushed out and discharged from the secondary compression box 31 more efficiently and reliably.

As shown in FIGS. 10 and 11, this is a straw cutter as a cutting means for cutting the straw W before being conveyed to the input conveyor 17 at a predetermined length, for example, 30 cm or 60 cm. The cutting machine 7 can also be installed on the upstream side of the input conveyor 17. Here, the cutting machine 7 includes a transfer conveyor 71 for transporting the straw W after being cut to the input conveyor 17, and a cutting mechanism 72 is provided on the upstream side of the transfer conveyor 71. . In this cutting mechanism 72, a rotating blade 73 having a plurality of cutting edges 72a attached at equal intervals in the circumferential direction is attached at equal intervals with a predetermined interval on the upstream side of the transfer conveyor 71. In other words, the rotary blades 73 are installed with an interval of the length of the straw cut by the rotary blade 83, and are inserted into the single drive shaft 74 so as to be rotatable. Further, the drive shaft 74 is configured to be rotationally driven by a drive motor 76 via a chain belt 75.
Therefore, the straw W is cut into a predetermined length by the cutting mechanism 72 of the cutting machine 7 and then sent to the input conveyor 17 to be input from the input conveyor 17 into the primary compression box 21 of the primary compressor 2. Thus, the length of the straw W at the time of the primary compression by the primary compressor 2 can be shortened, and the density variation at the time of the primary compression accompanying the difference in the diameter and density between the tip and the root of the straw W can be reduced. Therefore, the difference in partial density of the compressed straw C after the secondary compression by the secondary compressor 3 can be reduced, and the bundled straw D having a more uniform quality can be manufactured.
Here, this cutting machine 7 can also be provided with an aligner (not shown) as an adjusting means for stirring and aligning the straw W before being transported to the input conveyor 17. In this case, since the density and direction of the straw are adjusted and adjusted by the aligner, the straw is sent to the input conveyor 17 and input into the primary compression box 21 of the primary compressor 2. The amount of weight and weight of the straw W during the primary compression can be reduced, and the straw W can be more uniformly and efficiently subjected to the primary compression and the secondary compression. The binding straws D can be made, and the variation in quality when selling these binding straws D can be reduced.

In addition, a measuring machine for measuring the weight of the straw W conveyed by the input conveyor 17 can be attached to the downstream side of the input conveyor 17. Here, as this weighing machine, for example, when a predetermined amount of straw W is sent to the weighing machine, the predetermined amount of straw W rotates and tilts by its own weight, and the predetermined amount of straw W A mechanical configuration can be adopted in which the material is introduced into the primary compression box 21 from the introduction port 16. Further, as this weighing machine, in addition to a mechanical one that rotates and tilts by its own weight of a predetermined amount of straw W, a spring balance, a weighing machine by electronic control, or the like can be used.
Further, an air nozzle (not shown) is installed around the primary compression area 21d of the primary compression box 21 to prevent the straw W from being clogged in the primary compression area 21d. A configuration may also be adopted in which straws packed in the primary compression region 21d are blown away. In addition, a measuring machine for measuring the amount or weight of the straw W sent to the secondary compression area 31a of the secondary compression box 31 is attached to the secondary compression box 31 of the secondary compressor 3, and this It is also possible to add a metering control system that makes a predetermined amount of straw W sent to the secondary compression region 32a.
