Description

Detailed Description of the Invention

  According to the present invention, sugarcane can be reliably peeled from around the sugarcane stalk, and can be provided at a low cost without being provided with a complicated sorting device such as a wind sorter. It is about the system.

  For example, Patent Documents 1 and 2 include a hopper 2 that stores sugarcane that has been cut into a predetermined length, a trommel (rotary cylinder) 4, and a wind power sorter 8, and the cutting that is stored in the hopper 2. The supplied sugarcane is supplied to the trommel 4, and the trash such as earth and sand in the cut sugarcane is removed in the trommel 4. 8, a trash removal system configured to sort at least a cut sugar cane stem and a lighter trash than the chopped sugar cane in the wind sorter 8 is described.

  And in this invention, the removal process of the large stone and the root by the large stone / root removal apparatus, the removal of the sediment and the peeling of the hakama by the subsequent rotary trommel apparatus, the selection process of the healthy stem by the wind power sorter 8 It is explained that it is composed of.

  Further, the rotary trommel device is provided with a trommel (screen having a cylindrical surface, a rectangular tube shape, a truncated cone shape, or a pyramid shape) that is supported in an inclined manner. It is described that the inside of the trommel is sieved while being moved in the circumferential direction and the axially lower side.

  Further, the wind power sorter has a first chute 8d for a healthy stem, a second chute 8e for a treetop and the like for a dead branch and the like for a dead branch and the like in a direction away from the blow nozzle 9a (from heavy to light). It is described that a three chute 8f is provided.

  However, in the present invention, in addition to the removal of earth and sand by the rotary trommel device 4 and the peeling process of the hakamama, the removal of the large stones and roots by the large stone / root removal device 2 and the selection of the healthy stem by the wind power sorter 8 A process is separately required, and the structures of the large stone / root removing device and the wind sorter 8 are extremely complicated.

  In addition, the rotary trommel device rotates a trommel having a screen having a cylindrical surface, a rectangular tube shape, a frustoconical shape, or a pyramid shape so that the object to be separated is reduced in the circumferential direction and the axial direction in the trommel. Since the screen can be screened while being moved, the screen surface cannot sufficiently peel off the sugarcane around the sugar cane stalk, and the stones and fibers that are trash clog the screen.

  Further, the wind power sorter has a first chute 8d for a healthy stem, a second chute 8e for a treetop, etc., and a second chute for dead leaves and the like in order from the air nozzle 9a (from heavy to light). Since the three shoots 8f are provided, the selection by such wind force is based on the difference in weight. For example, the top of the treetop is mixed into the first shoot 8d or the dead leaves are mixed into the second shoot 8e. .

  Further, in Patent Document 3, a transport means for transporting the treetop from the distal end side to the proximal end side is arranged on an arm supported by the vehicle body so that it can turn left and right and rotate up and down with the proximal end side as a fulcrum. The arm is provided with a cutter for cutting the lower end of the top of the top of the arm, and a scraping means that is opened in an inverted 8-character shape in front of the cutter is disposed on the vehicle body. A sugarcane treetop harvesting device and a harvesting method provided with a means for taking in the coming treetop into the shredding device are described.

  And, it is an apparatus and method for harvesting sugarcane treetops that are raw materials for honey sugar and brown sugar, and by making it possible to harvest only the sugarcane treetops, it is possible to secure a large amount of feed such as cows and horses, Moreover, it is explained that the top of the treetop is prevented from being mixed into the stem that is a raw material for sugar.

  Further, Patent Document 4 discloses a transport unit that transports sugarcane cut pieces that have been cut to a substantially predetermined length in a substantially aligned manner, and only the top of the top of the sugarcane cut pieces that are transported by the transport unit. And a selection means for selecting from healthy stems that are sugarcane cut pieces, the selection means has a pair of holding bodies, and both holding bodies can hold the top of the treetop but cannot hold the healthy stem. A release angle position of the treetop head that is opened at the opening angle formation start position, and has an opening angle formation start position where the pinching angle formation start position where the pinching angle is formed and an opening angle formation start position where the pinching of the treetop head is released are opened. There is described a sugarcane treetop sorting apparatus that can separate the release drop position of a healthy stem portion that is released before reaching the keratinization start position.

  And it is described that in this treetop head sorting apparatus, the treetop head and the healthy stem can be sorted with an accuracy of about 100%.

  However, these devices require a separate device for selecting the top of the treetop and are extremely complicated in structure, and cannot be provided inexpensively as a whole sugarcane refining system.

Problems to be solved by the invention

  The present invention peels off the sugarcane from around the sugarcane stalk by a blade in the trommel, and discharges it from the sugarcane stalk supply side through the inside of the tubular part of the troughmel by a blower provided on the sugarcane stalk supply side without sorting by light weight difference by wind power. The trash can be efficiently and surely sorted by blowing air to the side, and the overall structure of the sugarcane refining system can be provided very simply and at low cost. Stones and fibers that are trash do not cause clogging of the trommel, and when the trommel rotates, Even if both ends of a healthy stalk collide with its inner surface, it can be peeled off without damaging the sugar cane stalk, and a simple configuration without using a separate sorting device such as a wind sorter with a single trommel It can remove trash such as hakama and stone almost completely, and the blade shape can surely peel off the sugarcane around the sugarcane stalk, and both ends of the sugarcane healthy stalk can be damaged by the blade shape and many blades The present invention provides a sugarcane refining system that can remove trash without trash.

Means to solve the problem

[0016]
[Means for solving the problems]
The invention of claim 1 includes at least a hopper that accepts a sugarcane stem cut to a predetermined length, a trommel that accepts the sugarcane stem from the hopper and removes the sugarcane trash, and a trombol sugarcane on the sugarcane stem discharge side. A bag of trash discharged from the supply side by a blower, a treetop sorting section that receives the sugarcane stems from which the trash has been removed and removes the treetop head, and a healthy sugarcane stem from which the treetop head has been removed in the treetop selection section A sugarcane refinement system comprising a bagging portion to be packed, wherein the trash removal trommel is formed of a resin material having a smooth inner surface that is not reticulated, and the trash is passed from the sugarcane supply side to the sugarcane supply side. A blower that blows air in the discharge direction In addition, the trommel is provided in an inclined shape so as to be lowered at an angle of 3.2 to 8.0 degrees in the sugarcane stem discharge direction, and the inner surface has a blade portion in the rotation direction parallel to the sugarcane discharge arrangement direction. The blade is provided with three or fewer rows in the rotational direction on the inner surface of the trommel, and a corrugated blade that rises in the inner peripheral direction is formed on the sugar cane contact side to peel off the sugar cane hook. It provides a sugarcane removal system with a width of 5 to 80 mm, a corrugated blade tip having a curved shape, a corrugated blade pitch of 5 to 50 mm, and a corrugated blade depth of 3 to 15 mm. is there.

In the present invention, the cocoon is peeled off from around the sugar cane stalk by a blade in the trommel, and without being sorted by the difference in weight due to wind force, the blower provided on the sugar cane stalk supply side allows the sugar cane stalk supply side to pass through the inside of the trowel. By blowing air to the discharge side, the rush can be efficiently and reliably selected, and a sugarcane refinement system that is simple and inexpensive as an entire sugarcane refinement system can be provided.

Further, in the present invention, the trommel is formed of a resin material having a smooth inner surface that is not a metal net, so that the trash stones and fibers do not cause clogging of the trommel, and both ends of the healthy sugar cane stems when the trommel rotates. Can peel the sugarcane around the sugarcane stem without damaging it even if it hits the inner surface, and it can be configured concisely without a separate sorting device such as a wind sorter with a single trommel, such as a hakama or stone The trash can be removed almost completely. If the inclination angle of the trommel in the discharge direction is less than 3.2 degrees, the sugarcane stalk cannot be rapidly transferred in the discharge direction, and if it exceeds 8.0 degrees, the transfer speed in the discharge direction is too fast. Cannot be sufficiently peeled off.

Furthermore, in the present invention, the blade shape can surely peel off the sugarcane surrounding the sugarcane stem, and the trash can be removed without damaging both ends of the sugarcane healthy stem with the blade shape or multiple blades. If the rising width is less than 5 mm, the sugarcane stalk cannot be reliably peeled off, and if it exceeds 80 mm, the sugarcane stalk is too large to reversely peel off the sugarcane stalk. At the same time, the peripheral surface of the healthy stalk and the both ends of the cut are easily damaged, leading to short-term rot of the sugarcane stalk. Further, when the pitch of the corrugated blades is outside the range of 5 to 50 mm and the depth of the corrugated blades is outside the range of 3 to 15 mm, the sugarcane stalk cannot be reliably peeled off.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is a schematic overall plan view of a sugarcane refining system, FIG. 2 is a view taken along line II of FIG. 1, FIG. 3 is a view taken along line II-II of FIG. 1, and FIG. FIG.

  The sugarcane stem A1 (FIG. 5) cut into a predetermined length by the harvester is stored in the hopper 1. The sugar cane stem A1 is intermittently and sequentially supplied from the hopper 1 through the feeder 2 to the trommel 3 for removing the sugar cane trash. In this trommel 3, trash such as scallop B (FIG. 6) attached to the periphery of healthy sugarcane stem A 2 and sugar cane stem A 1 is removed.

  As shown in FIG. 7, the trommel 3 is a cylindrical rotating body and is made of a resin material having a smooth inner surface, for example, vinyl chloride. The trommel 3 is provided with a blower 4 that blows air in the trash discharge direction (arrow X). The trommel is provided so as to be inclined at an angle Y of about 4.5 degrees in the direction of sugarcane stem discharge. This angle Y can be provided in an inclined manner so as to be low in the range of 3.2 to 8.0 degrees. Preferably it is the range of 4.0-6.0 degree | times. The reason why the inner surface smooth resin material, for example, vinyl chloride is used, is that the both ends cut portions A4, A4 (FIG. 6) of the sugar cane stalk are not crushed, and the both ends cut portions A4, A4 of the sugar cane stalk are metal surfaces. And the like (which occurs when the sugarcane stalk A1 falls downward from above due to the rotation of the trommel), it collapses and the progress of decay from that part becomes extremely fast.

  As shown in FIG. 8, blades 5... Parallel to the direction in which the sugar cane stems A <b> 1 are discharged are provided on the inner peripheral surface of the trommel 3, and the sugar cane hook B is peeled off from the sugar cane contact sides of the blades 5. The corrugated blade M is formed.

  The rising width L of the blade 5 is 5 to 80 mm, the tip of the corrugated blade M has a curved shape N, the pitch O of the corrugated blade M is 5 to 50 mm, and the depth P of the corrugated blade M Is 3 to 15 mm. Preferably, the rising width L is 15 to 50 mm, the tip of the corrugated blade M has a curved shape N that is close to or smaller than the curvature A3 (FIG. 6) of the sugar cane stem, and the corrugated blade M The pitch O is 10 to 20 mm, and the depth P of the corrugated blade M is 5 to 10 mm. Further, it is preferable that the blades 5... Are not formed in four or more rows in the rotation direction in order to prevent contact with the metal surface (blade) that occurs when the sugarcane stem A1 falls from the upper side to the lower side due to the rotation of the trommel.

  The trash such as Hakama B removed by the trommel 3 is discharged to the trash discharge field 6 by the wind force of the first blower 4 and the second blower 7 (FIG. 2). On the other hand, the healthy sugarcane stem A2... And the treetop head C (FIG. 9) from which the trash has been removed are sent to the treetop head sorting section 9 (conveyor) via the feeding device 8.

  In the treetop head sorting section 9, the sugarcane healthy stems A <b> 2... Are sent to the final feeding device 10, while the treetop head C is manually sorted and supplied to the treetop feeding device 11. The treetop head C selected from the treetop head sorting section is sent to the livestock feed production unit 12 via the treetop head feeding device 11, where the treetop head C is cut and the livestock feed is produced. As a result, the top of the treetop C can be made into a feed or food in an integrated manner with this system. The manufactured livestock feed is loaded on the loading platform of the truck 13 and conveyed.

  On the other hand, healthy sugarcane stems A2,... Are sent to the bagging unit 14 via the final feeder 10, where they are packed and loaded onto a truck bed by a crane (not shown). The two bagging frames 14 and 14 are provided with bags 16 and 16 inside, for example, as shown in FIG. 1, rails 15 and 15 are provided at the bottom so as to be movable so that they can be alternately packed. Yes.
