Description

  The present invention relates to a bamboo cutting adopted chipper, a bamboo collecting system, and a bamboo collecting method, and more particularly, to a bamboo cutting adopted chipper, a bamboo collecting system, and a bamboo collecting method for collecting and collecting bamboo in the vicinity of a bamboo forest and forming chips.

  In recent years, many studies have been made from the viewpoint of securing energy using biomass or producing fertilizer and the like from biomass. For example, Patent Document 1 proposes a “vegetable biofuel reforming method, system and production method” that makes it possible to reform bamboo into fuel, for example, as a biomass, and to obtain fertilizer from bamboo. Yes.

Japanese Patent No. 5757959

  Bamboo is a familiar material that has long been used as a souvenir, furniture, and household equipment for consumer use, but it is used industrially for combustion and further modified for use as a fertilizer The fact is that there has not been a lot of research that aims to achieve this.

  Bamboo is a material material that is not suitable for burning in a combustion furnace for power generation or incineration because of its low combustion temperature and the formation of a melt during combustion. However, bamboo can be used as fuel in an industrial combustion furnace if the problem proposed in the combustion is solved by adopting the method proposed in Patent Document 1 above. At the same time, it is possible to secure fertilizer.

  When bamboo is used for the above power generation and fertilization, it is necessary to cut a large amount of bamboo from the bamboo forest and transport it to a factory, etc., but the actual situation is that mechanization is not progressing when collecting bamboo. However, there is a problem in that handling as biomass fuel that is consumed in a large amount requires much work by the human world, and collection cannot catch up with consumption.

  The main reason for this is that in conventional bamboo collection, pre-treatment work such as pruning bamboo branches and cutting for truck transportation is necessary so that bamboo can be used for charcoal, aggregates, hedges, etc. The decrease in transport efficiency (the space ratio is large) with the bamboo shape remains.

  Of these operations, when it comes to transportation, it can be transported in chips, and although transportation efficiency is increased, on the other hand, the chipper blade has a short life, and the chipper screen is frequently clogged with bamboo water. There is a problem. For this reason, mechanization is not progressing.

  Furthermore, the problems in each work are summarized as follows. When bamboo is made of bamboo charcoal, etc., the bamboo is first cut and cut into a standard length of about 2.5 m, which is a size that can be placed on a light truck in the bamboo forest, and the leaves and leaves are pruned to be bulky during transportation and discarded in the bamboo forest. This means that in the scene of industrial use, branches and leaves are not subject to fuel, which is not economical.

  Also, in the scene of logging, if the bamboo inhabiting interval is narrow, the branches get entangled at the top and do not fall down even if the bamboo is cut, it is necessary to turn the cut bamboo and cut the entangled branches at the top, which causes human power Yes.

  In order to make this pruned bamboo into fuel, it is shredded by a shredder called a chipper. At this time, if bamboo water or the like is present in the bamboo, the moisture rises inside the chipper and is clogged by the screen at the outlet of the chipper. Work using some heavy machinery such as bamboo cutters has also been introduced, but manual work such as pruning and regular cutting has occurred.

  In addition, a method of chopping with a chipper has been adopted in order to increase transportation efficiency, but the work position of the chipper is in the vicinity of the truck in consideration of subsequent transportation, and bamboo from the bamboo forest to the chipper is heavy machinery or human beings It is necessary to carry.

  In view of the above, the present invention aims to provide a bamboo cutting chipper, a bamboo collection system, and a bamboo collection method that enable mechanization of bamboo cutting and conveyance work that has been performed mainly in human power. .

  From the above, in the present invention, the feed roller that feeds the bamboo that is sheared at the bottom, the knife that breaks the bamboo, the crusher that crushes the broken bamboo into a strip shape, and the strip-shaped bamboo is shredded The chipper is a bamboo chipping chipper that is provided with a chipper crushing section and pumps the chopped bamboo.

  Further, in the present invention, the bamboo is gripped at a plurality of locations on the upper part, the gripped bamboo is sheared at the lower part, a heavy machine for guiding the sheared bamboo, and the sheared bamboo guided by the heavy machine are received, A chipper that breaks, crushes, and shreds the bamboo, a chip transport hose that transports the shredded bamboo, and a pressure feeding means that pumps the bamboo from the chipper through the chip transport hose. This is a bamboo collection system.

  Furthermore, the present invention is a bamboo collecting method characterized by shearing bamboo, breaking the sheared bamboo, crushing the broken bamboo, chopping the crushed bamboo, and transporting the chopped bamboo by pumping Is.

  At present, bamboo logging, collection, processing, etc. require human intervention in each process, and labor saving and mechanization have not been achieved, but mechanization is possible according to the present invention.

  The embodiment of the present invention has the following effects. First, bamboo felling and chipping can be done by one person, and the logging, pruning, and regular cuts that were previously done in the human world are no longer necessary, and the harvesting efficiency per hour increases dramatically. Next, the standardized bamboo was transported to the truck in the human world, but efficiency can be improved by converting it into chips and carrying it in an air stream. In addition, it is possible to reduce the maintenance frequency and to enable continuous operation by attaching a pre-treatment device for the chipper that is indispensable for maintenance, such as clogging the screen of the chipper and short-time wear of the blade, and changing the structure of some parts.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a configuration example of a bamboo collection system according to Embodiment 1 of the present invention.

  In the bamboo collecting system of the present invention, a bamboo felling heavy machine 1 (hereinafter simply referred to as a heavy machine) enters the bamboo forest 100 to cut the bamboo 2, and the chipper 3 disposed adjacent to the heavy machine 1 includes the bamboo forest 100. Make bamboo 2 chips on site. Further, in the vicinity of the felling site, a vacuum car 5 is laid side by side as a transport vehicle for transporting the bamboo 2 that has been chipped, and a chip transport hose 4 is disposed between the chipper 3 and the vacuum car 5 so that the chip Is pumped from the chipper 3 to the vacuum car 5.

  As described above, the bamboo collection system according to the first embodiment of the present invention is a method of transporting after chipping in the field. To describe this in detail, the bamboo 2 cut by the heavy machine 1 is put into the chipper 3. It is made into a chip. At this time, the bamboo to be put into the chipper 3 is cut down and is not pruned. The chipper 3 is controlled to always move to a position several meters away from the heavy machinery 1 by remote or communication.

  Chips crushed by the chipper 3 are sent to a vacuum car 5 through a chip transport hose 4 and collected. The general vacuum car 5 has a shape in which a cylinder is placed sideways because liquid is a target as a carrier substance. However, since the bulk density is low, the chip adopts a shape in which a vacuum device is attached to a normal truck. It is characteristic.

  2a, 2b, and 2c show a configuration example of the heavy machine 1 suitable for the embodiment of the present invention in the bamboo collection system shown in FIG. In particular, a configuration of a heavy machine tip attachment that is provided at the tip of an operating arm of the heavy machine 1 and is suitable for gripping and cutting the bamboo is shown.

Here, when the heavy equipment tip attachment provided at the tip of the working arm of the heavy equipment 1 is configured, the required functions and specifications are as follows. Generally, bamboo shoots farmers Takebayashi are bamboo per 2-3m ² is managed so as to be one, the left Takebayashi sometimes 5-8 pieces of bamboo per 1 m ² are concentrated. In this case, it is necessary to process one bamboo at a time to perform the pre-processing described later. However, since the conventional bamboo logging device is a technology that has spread from timber harvesting, the attachment is large and several bamboos are harvested together. Although it is suitable for, it is not suitable for one by one. In this case, there is a method in which several pieces are bundled and added one by one after felling, but if bamboo is left in the bamboo forest, mud adheres to the surface of the bamboo and the cutting cut. When this mud enters the chipper 3, the blades wear out in a short time, and the maintenance frequency increases and becomes inefficient.

  In response to such a problem, the heavy equipment tip attachment according to the embodiment of the present invention adopts the configuration of the top view of FIG. 2a, the configuration of the plan view of FIG. 2b, and the cutting portion enlarged configuration of FIG. First, according to FIG. 2A when the main body including the hydraulic unit 17 is viewed from above, the holder rotated by the hydraulic unit 17 is provided with two sets of anti-circular holders 18 supported so as to be rotatable at one point. The bamboo 2 is held between 18. According to the plan view of FIG. 2b, the plurality of holders 18 are arranged in the height direction, so that the bamboo 2 can be stably held at a plurality of locations. A cutter 21 that moves forward and backward by a hydraulic cylinder 20 for cutter is provided below the plurality of holders 18, and the cutter 21 that moves forward while the bamboo 2 is gripped by the holder 18 cuts the bamboo 2. As shown in FIG. 2c, the cutter 21 moves back and forth along the cutter guide 19, its forward position (operating position) is indicated by a dotted line, and the backward position (accommodating position) of the cutter 21 is indicated by a solid line. Like to shear the bamboo when moving forward.

  In this way, the holder 18 connected to the hydraulic unit 17 grips the bamboo 2 in such a size that it can grip a maximum of 25 mm diameter of one bamboo. The holder 18 has a shape that intersects with the left and right, and the small holder 18 is overlapped and gripped. When the bamboo 2 is gripped, the cutter 21 at the bottom is moved from the cutter housing position shown by the solid line to the dotted cutter operation position by the cutter hydraulic cylinder 20, and the bamboo 2 is sheared. The shape of the cutter 21 is slanted like a guillotine knife, and the thickness direction is also slanted, and the bamboo 2 is sheared by a sharp cutting edge.

  3a, 3b, and 3c show a configuration example of the chipper 3 suitable for the embodiment of the present invention in the bamboo collection system shown in FIG. 3a is a plan view showing the overall configuration of the chipper, FIG. 3b is a side view showing the overall configuration of the chipper, and FIG. 3c is a diagram showing the configuration of the screen portion inside the chipper.

  First, the overall configuration of the chipper shown in FIGS. 3a and 3b will be described. In the present invention, when examining the overall configuration, a configuration capable of preventing the tip of the chipper blade from being damaged was examined. The conventional chipper 3 has no pretreatment and simply sends bamboo into the machine for pulverization. In this case, screen clogging occurs due to bamboo water and the like, and the wax component called the bamboo deformation on the bamboo surface and the wax component called bamboo wax on the bamboo surface causes the chipper blade to slip on the bamboo surface, resulting in a problem that the cutting edge is lost.

  In order to prevent this, in the overall configuration of the chipper of FIGS. 3a and 3b according to the present invention, the bamboo 2 thrown into the chipper 3 from above is sent to the knife 11 by the feed roller 10 so that the height is increased. Divided in half. As a result, the bamboo water inside is exposed to the outside. The bamboo water that has come out falls to the drain discharge part 12 and is discharged outside. The bamboo that has been broken in half is guided by the guide plate 13 to the crusher section 14 with the bamboo inner surface facing upward. The bamboo that has entered the crusher 14 is crushed into a fine strip shape, and the bamboo is almost free from elastic deformation, and is carried to the chipper crushing portion 15 and chopped. The shredded bamboo 2 is guided to the hose connecting portion 16 via the screen portion 7 provided at the lower portion of the chipper crushing portion 15. The chipper crushing unit 15 includes a plurality of rotating blades 15b that are connected to the rotating shaft 15a and rotate, and the rotating blades 15b cut the bamboo that has entered into chips.

  As described above, the feature of the chipper 3 of the present invention can be said to be an apparatus having a pretreatment function. Before the shredding by the chipper 3, the bamboo is divided in half and the internal bamboo water is removed in advance. By making the bamboo surface that hits the inside soft, and then crushing with a crusher, elastic deformation is eliminated, and the life of the blade can be extended. In addition, for the half-bamboo bamboo, the blade is prevented from skidding by the bamboo surface by guiding the rotary blade 15b from the inside of the half-bamboo to the surface side of the bamboo to prevent the blade from being lost. Yes.

  FIG. 3c shows the screen portion 7 inside the chipper, and is a view of the inside of the chipper crushing portion 15 seen from the direction of arrow Y in FIG. 3b. There is a rotary blade 15b in the foreground, the rotary shaft 15a in the center, and the screen 7 in the back of the rotary blade 15b. In constructing the screen portion 7 of FIG. 3c, it is necessary to consider clogging of the chipper screen portion 7. The bamboo 2 is crushed by the rotary blade 15b attached to the rotary shaft 15a inside the chipper crushing unit 15, but the chipper crushing is performed as shown in FIG. The screen unit 7 is installed at the lower part of the unit 15. However, when the water content of the bamboo pulverized with bamboo water or rainwater rises, a phenomenon that the bamboo is clogged with the screen portion 7 occurs.

  According to the knowledge of the inventors, normal raw bamboo contains about 50% of water, whereas stuffed bamboo contains about 70% of water. In addition, this clogging is not a tightly clogged thing and can be easily cleaned by applying tap water, but it requires human work each time.

  Therefore, in the present invention, the countermeasure against chipper clogging is eliminated by using the vacuum pressure accompanying the pressure feeding of the chip, which will be described later. Further, although the holes of the conventional screen have a horizontal distance corresponding to the thickness of the plate, the clogging is cheaper. However, as shown in FIG. Suction by vacuum pressure from the side. In this way, the resistance of the bamboo to be clogged is eliminated except for the first passage through the hole, and clogging can be eliminated even with a very small differential pressure.

  As described above, the screen of the general chipper 3 has a structure in which bamboo passes by its own weight, but may be clogged when there is a lot of moisture. Therefore, even when collecting bamboo in heavy rain, it is effective against the screen by pulling it with vacuum, and clogging can be eliminated by changing the screen hole shape and eliminating the horizontal distance.

  Next, problems and countermeasures when the chip is pumped in the overall configuration of FIG. 1 will be described with reference to FIG. In the present invention, a chip transport hose 4 is provided between the chipper 3 and the vacuum car 5, and chips are pumped from the chipper 3 to the vacuum car 5. For this reason, it is necessary to cope with clogging in the hose 4.

According to the method shown in FIG. 1, the flexible hose 4 can be used to set a free transportation route in the bamboo forest. On the other hand, when the hose 4 is bent, the chip flowing inside accumulates and the possibility of clogging is “0”. "It can not be said. As a countermeasure against this, if the relationship between the vacuum pressures that can actually be used is closely examined, the suction is performed by the vacuum car 5 so that the pressure is -1 kg / cm ^{2 at} the maximum. The pressure resistance of the hose 4 is about −1 to 8 kg / cm ² .

Therefore, in the present invention, when clogged at −1 kg / cm ² , the system configuration is such that positive pressure can be applied from the chipper 3 to be eliminated. Specifically, first, a built-in compressor 23 is installed in advance in the chipper 3 to store compressed air. If the hose 4 is clogged, it is detected by the suction pressure of the vacuum car 5 rising, and the chipper 3 and the vacuum car 5 are once stopped. Next, after the chipper outlet valve 24 is closed to prevent the backflow of compressed air, the emergency compressed air valve 25 is gradually opened to increase the pressure inside the hose 4. Thereafter, the vacuum car 5 is operated to eliminate clogging.

  In Example 1, although the case where a chip | tip is conveyed by truck transport from logging sites, such as a bamboo forest, the case where a bamboo forest exists in the vicinity of a factory is assumed in Example 2. FIG.

  FIG. 5 shows a configuration example when the bamboo forest 100 and the factory are close to each other (within about 1 km). In consideration of pressure loss, a chip blower 26 is installed at the outlet of the chipper 3 instead of a vacuum car. Although the inside is negative pressure, it conveys by making the chip blower outlet positive pressure. The bamboo forest 100 is transported by the chip transport hose 4 so that a route can be freely taken. From the bamboo forest outlet to the factory, a fixed pipe 27 is used to connect to the cyclone separator 28 installed on the top of the chip storage silo 29 in the factory. A vacuum fan 39 is installed at the outlet of the cyclone separator 28 and is controlled so that the outlet of the cyclone separator 28 has a constant pressure.

  Thus, as a system configuration in the case where the bamboo forest is at a short distance from the factory, chips are transported by a combination of a vacuum fan and a transport fan instead of a vacuum car. In the case of the second embodiment, needless to say, the chipper 3 adopts the configuration shown in FIGS. 3a, 3b, and 3c.

  As shown in Example 1 in FIG. 1, the heavy machinery 1 and the chipper 3 are arranged at adjacent positions, so that the sheared bamboo 2 can be efficiently guided to the chipper 3. In the third embodiment, an arrangement relationship between the heavy machine 1 and the chipper 3 that enables efficient work will be described.

  FIG. 6 a shows the relationship between the heavy machine 1 for cutting bamboo and the chipper 3. In FIG. 6a, the heavy machinery 1 is provided with an operating arm 101 at the front and position sensors 31 and 32 at the left and right of the rear. In addition, on the right side of the front part of the chipper 3, an induction conveyor 36 for receiving sheared bamboo is provided, and position sensors 33 and 34 are provided on the left and right sides of the front part.

  FIG. 6 b shows the arrangement of the induction conveyor 36 in the chipper 3 in the height direction. The induction conveyor 36 is attached by an induction conveyor hinge 37 so as to extend forward and upward from the chipper 3. FIG. 6 c is a view of the induction conveyor 36 in the chipper 3 viewed from above. The left-right direction is supported by a fixed spring. As a result, the upper and lower sides are fixed, and the left and right sides are free.

  According to the configuration of FIGS. 6a, 6b, and 6c, the chipper 3 is maintained while keeping the inter-vehicle distance 35 constant by the sensors (31-34) attached to the heavy machine 1 and the chipper 3 so that the respective front end portions do not contact each other. Follows and moves to heavy machinery 1. Specifically, if the driver of the heavy machine 1 selects the remote control device so that the chipper 3 comes to the front right side, the sensor 32 on the heavy machine 1 side communicates with the sensor 34 on the chipper 3 side, and the inter-vehicle distance 35 The chipper 3 moves so as to keep Further, the chipper 3 automatically moves so that the sensor 31 and the sensor 34 are in a linear position from the relationship between the sensor 33, the sensor 31, and the sensor 34.

  On the other hand, when the work efficiency is better when the chipper 3 is on the left side due to the arrangement of the bamboo forest 100, when the driver of the heavy machine 1 selects the left chipper, the control of the heavy machine 1 side sensor 32 and the chipper 3 side sensor 33 starts and the inter-vehicle distance 35 The chipper 3 moves so that becomes constant. Similarly, fine adjustment is performed while confirming at the position of the sensor 34 so that the sensor 32 and the sensor 33 are in a linear position.

  When logging bamboo with heavy equipment 1, cut bamboo at a few centimeters from the ground. In terms of efficiency, the shortest time is to put it into the chipper 3 in this state, but when trying to insert the tip of the bamboo into the feed roller 10 of the chipper 3, the attachment holder 18 holding the bamboo is loosened and slightly above the cutting position. Needs to be grabbed again and put into the chipper 3. If this work is performed in the bamboo forest, it is necessary to place the bamboo on the ground once in addition to the loss of time, and the mud of the bamboo forest adheres to the bamboo. It has been confirmed by tests and the like that when the mud adheres, the wear of the chipper blade proceeds rapidly.

  For this reason, an induction conveyor 36 is attached to the tip of the chipper 3 so that the sheared bamboo can be put into the chipper 3 as it is, and when the harvested bamboo is placed on the induction conveyor 36, the bamboo is sent into the chipper 3 by the induction conveyor 36 and is fed by the feed roller 10. Carried to the preprocessing position. Normally, the induction conveyor 36 does not come into contact with the heavy machine 1 at a distance 35 between the vehicles, but there is a possibility that the leading end of the heavy machine may come into contact with the bamboo or may come into contact with the falling bamboo in the bamboo forest. Therefore, the guide conveyor hinge 37 can move left and right to avoid impact. When there is no impact, the guide conveyor left and right fixing spring 38 is always fixed so as to be in a linear position at the entrance of the chipper.

  As described above, the present invention has been described according to the embodiment. The outline of the present invention can be summarized as follows.

  First, at the logging stage, bamboo cut with heavy machinery is put into a chipper and shredded. At this time, the branches and leaves are shredded regardless.

  Secondly, at the stage of shredding, first, the chipper is equipped with a device that always moves at a constant distance from the heavy machinery by remote or control so that the heavy machinery is immediately put into the chipper. Next, take the following measures to prevent clogging with the screen at the chipper exit with bamboo water. These measures include pre-processing the bamboo in half before draining the chipper and removing the bamboo water, processing the hole to widen to reduce the horizontal distance of the hole on the chipper screen, and chip transport by airflow by vacuum In order to prevent clogging, a differential pressure is applied to the screen.

  Furthermore, at the stage of shredding, if the bamboo is shredded with a chipper as it is, the bamboo wax and bamboo on the surface of the bamboo will be elastically deformed, causing the chipper blade to skid and causing the blade to be lost. After the splitting, pretreatment is performed so that the inner side first hits the chipper blade and is crushed with a roller to minimize elastic deformation.

  For the chipper pretreatment, it is necessary to cut out the bamboos one by one and put them into the chipper. However, the conventional method of cutting down the heavy machinery is to cut the attachment by attaching nata to the attachment that holds the bamboo at the tip of the heavy machinery or attaching a chain saw. ing. It is difficult to collect one bamboo at a time in places where the bamboo is dense, such as an abandoned bamboo forest, using a shearing method that involves lateral movement, such as nata and chainsaw. Therefore, the attachment width is narrowed by a special cutter so that the bamboo can be picked one by one.

  In addition, when clogged in the hose between the chipper and the vacuum car, the compressed air stored in the air compressor built in the chipper is put in the hose to increase the differential pressure and eliminate clogging. A system is attached.

  According to the present invention described above, it is possible to mechanize bamboo cutting and conveying work that has been performed mainly by human power, but this is a method that is economically effective. For example, according to a trial calculation example, compared with the conventional case where the bamboo is transported to the factory and chipped, the method of chipping by the method of the present invention at the bamboo forest site requires the transportation and chipping. It has been confirmed that the cost is about half.
