FIG. 5 is a conceptual diagram of the circuit configuration of the power system of the self-propelled recycling machine of the present embodiment.
In FIG. 5, the circuit of the self-propelled recycling machine of the present embodiment is largely divided into a work circuit 46 and a travel circuit 47. The working circuit 46 is a part related to a series of wood crushing operations in which the wood to be crushed is received, crushed and discharged, specifically, the operation devices of the wood crusher main body 2 and the discharge conveyor 3 described above. Refers to the drive circuit. On the other hand, the travel circuit 47 is a drive circuit for the travel device 1.

  The work circuit 46 includes an electric motor (electric motor) 50 provided as an actuator for rotational operation, a hydraulic cylinder 60 provided as an actuator for translation operation, a hydraulic pump 62 that discharges pressure oil supplied to the hydraulic cylinder 60, and the hydraulic pressure An electric motor 63 that drives the pump 62 and a control valve 61 that controls the flow rate and direction of the pressure oil supplied from the hydraulic pump 62 to the hydraulic cylinder 60 are provided. The electric motor (the electric motor 50 and the electric motor 63) of the work circuit 46 converts electric power supplied from the external power supply 45 into driving force.

  In the self-propelled wood crusher described in FIGS. 1 to 4, an electric motor (not shown) that rotationally drives the crushing rotor 32 of the crushing device 13 and an electric motor that rotationally drives the drive wheels 15 of the feed conveyor 12 (see FIG. 1). The electric motor 50 includes an electric motor (not shown) that rotates the pressing roller 17 and an electric motor 23 that rotates the driving wheels of the discharge conveyor 3. On the other hand, the hydraulic cylinder 60 includes a hydraulic cylinder 26 that rotates the pressing roller device 17, a hydraulic cylinder that rotates the screen holder 27, and the like.

  At the time of work, as shown schematically in FIG. 6, when the work circuit 46 is connected to the external power supply 45 and each electric motor 50 is energized by the control system that receives the operation signal from the operation system, Each electric motor 50 is driven to rotate in the direction of rotation instructed at the rotation speed corresponding to the operation. In addition, since the electric motor 63 is driven by the electric power supplied from the external power source 45 after the operation is started, when the control valve 61 is driven and controlled according to the operation of the operation system, the pressure oil from the hydraulic pump 62 is supplied to the hydraulic cylinder 60. The hydraulic cylinder 60 is expanded and contracted.

  The traveling circuit 47 includes a hydraulically driven traveling motor 70 (the traveling motor 8 in the self-propelled wood crusher described in FIGS. 1 to 4), a hydraulic pump 72 that discharges pressure oil supplied to the traveling motor 70, A pump driving motor 73 for driving the hydraulic pump 72, a control valve 71 for controlling the flow rate and direction of pressure oil supplied from the hydraulic pump 72 to the traveling motor 70, and AC power supplied from the external power supply 45 are converted to DC. Converter 76, a battery 75 that stores the electric power converted into direct current by converter 76, and an inverter 74 that converts the electric power stored in battery 75 into alternating current and supplies it to electric motor 73.

  With this configuration, a part of the electric power supplied from the external power supply 45 to the work circuit 46 during work is stored in the battery 74 as a power supply for travel (see FIG. 6). When the electric motor 73 is driven by the electric power stored in the battery 74 and the control valve 71 is driven and controlled according to the operation of the operation system (operation lever 29), the pressure oil from the hydraulic pump 72 travels as shown in FIG. The traveling motor 70 is operated according to the operation direction and the operation amount of the operation system using this as a driving force.

Next, operation | movement and an effect | action of the self-propelled wood crusher of the said structure are demonstrated one by one.
(1) At the time of crushing work When crushing work is performed, first, the work circuit 46 is connected to the external power supply 45 via a power cord (not shown), and an operation start (not shown) is instructed to start work. The electric motor including the electric motor is driven according to the setting by the control system that receives the operation signal. As a result, the discharge conveyor 3, the crushing device 13, the pressing roller device 14, the feed conveyor 12 and the like are sequentially driven to enter a working state.

  Thereafter, when the wood to be crushed, which is a recycled raw material, is introduced into the hopper 11 with a grapple or the like, the wood to be crushed is placed on the feed conveyor 12 in the hopper 11 and circulated while being guided by the inner wall of the hopper 11 on the side of the machine body. It is transported forward by the driven transport body 16. When the crushed wood is conveyed to the vicinity of the pressing roller device 14, the pressing roller 17 rides on the crushed wood, and the crushed wood on the feed conveyor 12 is pressed against the feeding conveyor 12 by the weight of the pressing roller device 14, and the feeding conveyor 12. And the pressure roller 17 are introduced into the crushing chamber 34.

  As a result, the crushed wood protrudes into the crushing chamber 34 in a cantilever shape with the portion sandwiched between the pressing roller 17 and the feed conveyor 12 as a fulcrum, and the crushing bit 31 of the crushing rotor 32 that rotates at high speed collides with this protruding portion. By doing so, it is roughly crushed. The coarsely crushed pieces of wood to be crushed go around with the rotation of the crushing rotor 32 in the crushing chamber 34 and collide with the crushing bit 31, the anvil 33, etc., and are further crushed by the impact force. . When the wood pieces are crushed to a particle size that passes through the screen 35 that constitutes a part of the wall surface of the crushing chamber 34 in this way, the crushed wood (wood chips) passes through the screen 35 and is discharged from the crushing device 13. Is done. Then, the crushed wood discharged from the crushing device 13 falls on the conveyor belt of the discharge conveyor 3, and is further conveyed forward of the machine body and discharged out of the machine as a recycled product.

(2) During travel During travel, the power cord is disconnected from the external power supply 45, and the power stored in the battery 74 during work is used as the travel power source. When the electric motor 73 is driven by the electric power stored in the battery 74 and the control valve 71 is driven and controlled in accordance with the operation of the operation lever 29, the pressure oil from the hydraulic pump 72 is supplied to the traveling motor 70, and this is used as the driving force. As a result, the traveling motor 70 operates in accordance with the operation direction and operation amount of the operation system. Thereby, the traveling device 1 operates according to the operation of the operation lever 29, and the self-propelled wood crusher travels.

  As described above, according to the present embodiment, the engine can be omitted, the crushing operation can be performed by the power supplied from the external power source during the operation, and the vehicle travels by the power supplied from the battery stored during the operation. be able to. Since no engine is required as a prime mover in this way, exhaust gas is not discharged and there is no pollution, and the load on the surrounding environment can be drastically reduced. Therefore, it is not necessary to ventilate the exhaust gas even when operating indoors, for example, at an operation site sealed with a soundproof wall. Moreover, since there is no engine sound, the effect of noise reduction is great. Since there is no engine sound, it is possible to reduce the burden on the soundproofing of buildings and the like even when operating indoors or in urban areas, and it is also advantageous to reduce the cost of buildings and the like.

  In addition, a commercial power source can be used at the time of work, and work can be performed inexpensively and safely. Of course, by utilizing the self-propelled function, the operating location can be moved appropriately according to the progress of the work, and the work space can be used effectively. The fact that the work space can be reduced also contributes to lowering the cost of buildings and the like when operating indoors or in urban areas. In addition, when running, the battery runs, so there is no need to connect to an external power supply with a power cable, and there is no restriction on the range of movement, so when operating in a wide field, it is convenient for traveling in the field and moving the operating position. High nature.

  Furthermore, in view of the operation mode of the self-propelled recycling machine that operates on a relatively long distance when operating on a wide site, but operates at a fixed position during work, the self-propelled of the present invention The type of recycling machine has a very rational machine configuration. In other words, it is necessary to operate a large number of actuators to work, and it is necessary to be able to withstand long-term operation, but self-propelled recycling machines operate and operate at a fixed position once the operating position is determined. However, the external power supply is the most suitable for supplying power during work. On the other hand, power supply by a battery is desirable so that the movement range is not restricted during travel, but the travel device is the only operating device that operates during travel. Therefore, the traveling circuit is separated from the working circuit, and it is sufficient to store only the electric power for driving the traveling device in the battery. Therefore, a small battery is sufficient. Therefore, the machine configuration is rational and simple, and in addition, since the engine is unnecessary, there is no need for a radiator, an air cleaner, or the like for cooling the engine cooling water. Great contribution.

  In FIG. 5, different hydraulic pumps 62 and 72 are provided for the working circuit 46 and the traveling circuit 47, and the hydraulic pumps 62 and 72 are driven by the electric motors 63 and 73, respectively. The circuit may be configured to share the hydraulic pump and the electric motor that drives the hydraulic pump. In this case, the same effect is obtained.

FIG. 8 is a conceptual diagram of a circuit configuration of a power system of a self-propelled recycling machine according to another embodiment of the present invention. In this figure, the same reference numerals are given to the same parts as those in the above-mentioned drawings, and the description will be omitted.
This embodiment is different from the previous embodiment in that an electrically driven traveling motor 70a is used instead of the hydraulically driven traveling motor. Since the electric travel motor 70a is used, the travel circuit 47a in the present embodiment does not require a control valve for supplying pressure oil to the travel motor, a hydraulic pump, a pump drive motor for driving the hydraulic pump, or the like. In the previous embodiment, the electric motor for driving the pump is driven by the electric power stored in the battery 75, but in this embodiment, the traveling motor 70a is directly driven by the electric power stored in the battery 75. In this case, when traveling, when a predetermined amount of electric power stored in the battery 74 is supplied to the traveling motor 70a in accordance with a command from the control system that receives the operation signal from the operation lever 29, the rotation corresponding to the operation is performed. The traveling motor 70a is rotationally driven in the rotational direction designated by the speed. Other configurations and operations are the same as those in the previous embodiment.

  In the present embodiment, in addition to the same effects as in the previous embodiment, there is an advantage that the traveling circuit can be simplified as compared with the case of using a hydraulically driven traveling motor.

FIG. 9 is a conceptual diagram of a circuit configuration of a power system of a self-propelled recycling machine according to still another embodiment of the present invention, and FIG. 10 is a schematic diagram showing a power supply state during traveling. In these drawings, the same parts as those in the above-mentioned drawings are denoted by the same reference numerals, and description thereof is omitted.
The difference between the present embodiment and each of the previous embodiments is that the power stored in the battery 75 and the power supplied from an external power source can be selectively used as a power source for the travel motor 70. . The external power supply for supplying power to the travel motor 70 may be an external power supply (working) 45 shared with the work circuit 46, or other external power supply 45a may be appropriately used as a travel power source.

  In the present embodiment, the traveling operation using the battery 75 as a power source is the same as that in the previous embodiment (see the dotted arrow in FIG. 10). The travel circuit 47 is connected to the external power supply 45a. Then, the electric power from the external power supply 45a is supplied to the travel circuit 47 via the inverter 74, whereby the electric motor 73 and the hydraulic pump 72 are driven, and the control valve 71 is driven according to the operation of the operation lever 29. The pressure oil is switched and supplied to the hydraulically driven travel motor 70 via the control valve 71, and the self-propelled recycling machine travels. At this time, part of the electric power supplied from the external power supply 45a to the electric motor 73 is converted into direct current through the converter 76 and stored in the battery 75 as in the work (see solid line arrow in FIG. 10). As described above, in the present embodiment, two types of power supply paths are provided in FIG. 10 that are distinguished by solid and dotted arrows, and can be selectively used. Other configurations and operations are the same as those in the previous embodiment.

  Also in this embodiment, the same effect as that of the embodiment of the self-propelled recycling machine of the present invention described with reference to FIGS. In addition to this, in the present embodiment, the battery 75 and the external power source can be selectively used as a power source, and therefore, the amount of charge of the battery 75 during work is insufficient and the running distance is insufficient. However, in the vicinity of the external power source, it is possible to take measures such as running the external power source as a power source and accumulating in the battery 75 during that time. Further, as described above, the traveling circuit 47 is independent of the working circuit 46, so that the power consumption is small. Even if an external power source is used for traveling, a small power supply facility and a relatively thin power cord are used. It is also an advantage to be sufficient.

  In the present embodiment, the self-propelled recycling machine having the hydraulically driven traveling motor 70 is configured to be able to travel with an external power source. For example, the present embodiment is combined with the embodiment described with reference to FIG. For example, in a self-propelled recycling machine having an electrically driven traveling motor, it goes without saying that the power source may be selectively used with a battery and an external power source to allow traveling.

  In the above description, the case where the present invention is applied to a self-propelled wood crusher in which the feed conveyor 12 is provided in the hopper 11 and the wood to be crushed is introduced from the lateral direction with respect to the crushing device 13 has been described as an example. However, it is not limited to this. For example, the present invention is also applicable to a self-propelled wood crusher in which a crushing device is provided in the lower part of the hopper and the wood to be shredded is introduced in the vertical direction with respect to the crushing device. In these cases, the same effect is obtained.

  In the above description, the present invention is applied to a self-propelled wood crusher as an example of a self-propelled recycling machine. However, the present invention can also be applied to other self-propelled recycling machines. It is. For example, a shearing machine (shredder) for shearing and crushing tires and home appliances, or a roll-shaped rotating body with a blade for crushing as a pair, and rotating the pair in the opposite direction to each other, between the rotating bodies A rotary crusher (roll crusher) that crushes rocks and construction wastes between them, and a crusher that rocks the moving teeth with respect to the fixed teeth and crushes rocks and construction wastes between them. (Jaw crusher), a crushing device (impact crusher) that rotates a striking plate having a plurality of blades at high speed, and impactably crushes rocks, construction waste, etc. using a striking from the striking plate and a collision with a repulsion plate The present invention can also be applied to various self-propelled crushers equipped with a crushing device (processing device). In these cases, the same effect is obtained.

  In addition, it is not limited to the self-propelled crusher that crushes such recycled materials, for example, accepts the soil to be treated as a recycled material and mixes it with an improved material to generate improved soil or improve the soil surface ground. The present invention is also applicable to other self-propelled recycling machines equipped with traveling devices, such as self-propelled soil improvement machines. Furthermore, it is not limited to a self-propelled recycling machine equipped with a processing device that crushes recycled materials or mixes them with other substances in this way, but it also sorts the size of recycled materials, recycled products, processing materials, etc. Naturally, the present invention can also be applied to a self-propelled sorting machine equipped with a sorting device (such as a sieve) or a self-propelled conveyor simply having a conveyor mounted on the traveling device. The self-propelled recycling machine to which the present invention is applied is not limited to a crawler-type traveling device having a crawler belt as shown in FIGS. It may be provided with a traveling device. In these cases, the same effect is obtained.
