An embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, an engine E is mounted in a bonnet 2 at the front of a vehicle body of a traveling vehicle 1, and the rotational power of the engine E is transmitted to a transmission in a mission case. The reduced rotational power is transmitted to the front wheel 3 and the rear wheel 4. A driver's seat 5 is provided on the rear side of the vehicle body, and a steering handle 6 is provided in front of the driver's seat 5.

  On the front side in the traveling direction of the traveling vehicle 1 is installed a water spraying means (moisture spraying device) 7 for spraying moisture on the soybean crops, and on the rear side in the traveling direction, it moves along the furrow between the left and right crop rows. A weeding means (herbicidal device) 8 is provided for weeding while excavating the top soil in the furrow groove.

  The moisture spraying device 7 includes a tank 9 for storing water (or a chemical solution), a pump 10 for sucking up water from the tank and ejecting the water from the spray nozzle, a spray hose 12 and a spray nozzle 13 installed on the spray boom 11 and the like. The spreading boom 11 includes a central spreading boom 11C and left and right spreading booms 11L and 11R connected to the left and right sides thereof. The left and right spreading booms 11L and 11R are arranged in the central boom. -It is connected and supported so as to be rotatable around the axial center in the front-rear direction with respect to the main body 11C, and the tip end side is rotated upward to be held in the stowed state, or it is substantially parallel to the ground and protrudes in the lateral direction. It can be rotated and supported in the spraying work posture state.

  The weeding device 8 includes a drive shaft 17 that is pivotally mounted on a chain case 16 and protrudes left and right, left and right plate bodies 18 and 19 having different diameters and held on the drive shaft 17, and left and right plates. It consists of a weeding blade 20 or the like connected laterally across the bodies 18 and 19, and three weeding devices 8, 8, 8 are arranged at predetermined intervals in the left-right lateral direction, and each kite U, It is set as the structure which excavates and weeds with the weeding braid | blade 20 while carrying out grounding rolling movement along the groove part between U and U. Each of the weeding devices 8, 8, 8 is configured to move up and down with respect to the vehicle body through an elevating link mechanism 21 by, for example, an expansion / contraction operation of a hydraulic cylinder mechanism.

  Behind the rotating weeding blade 20, there is a rollable gauge wheel 24 that moves to the ground. The gauge ring 24 is pivotally fixed around a horizontal axis 25 in the horizontal direction, and is normally fixed by a fixing pin 26 and cannot be rotated. When the fixing pin 26 is removed, It is configured to rotate rearward and upward with the shaft 25 as a fulcrum (imaginary line in FIG. 3). With this configuration, grass clogged between the gauge wheel 24 and the weeding blade 20 can be easily removed.

  The mounting pins 30 are inserted into the mounting holes 28 provided in the bearing boss portions 27 of the disk bodies 18 and 19 and the mounting holes 29 provided in the drive shaft 17 to integrally connect and hold them. When the mounting pin 30 is removed, the weeding blade 20 can be easily detached from the drive shaft 17 together with the disk bodies 18 and 19. Therefore, the weeding blade 20 can be easily attached to and detached from the drive shaft 17 without requiring a tool, and the grass caught in the narrow space between the inner surface of the weeding blade 20 and the chain case 16 can be easily removed.

  Further, as shown in FIG. 6, the weeding blade 20 is configured such that the outer end side is appropriately inclined with respect to the rotation direction so as to maintain the receding angle θ from the inner end side. According to this, the grass to be excavated will be discharged while being gradually moved toward the outside, and it is possible to prevent the grass from being caught in the chain case 16 side.

  In the embodiment shown in FIGS. 8 and 9, by making the outer diameter of the disk body 19 on the side of the chain case 16 larger than the rotating outer diameter of the blade 20, the grass cut off by the blade enters between the chain case. It can be blocked by the large diameter portion 19a.

  Further, according to the embodiment shown in FIG. 10, the inclined portion 20s is provided so as to be inclined at a predetermined angle α so that the outer peripheral rotation diameter of the blade 20 becomes smaller toward the outer side than the inner side (chain case 16 side). Therefore, it is possible to discharge the scraped grass toward the outside, and to prevent the grass from being caught on the chain case side.

  The embodiment shown in FIGS. 11 and 12 will be described. Between the chain case 16 and the weeding blade 20, a cylindrical anti-winding cylinder 32 having a smaller diameter than the outer peripheral rotation locus of the blade 20 is interposed. So that the grass 20 is prevented from being caught between the blade 20 and the chain case 16. A fixture 33 is projected from the chain case 16, and a circular plate 34 is attached to the fixture 33 so that a gap between the side surface of the chain case 16 and the circular plate 34 is not generated. Has a structure in which the winding preventing cylindrical body 32 is integrally fixed and does not rotate so as to prevent grass from being caught.

  Further, as shown in FIGS. 13 and 14, an anti-winding cylindrical body 32a having a smaller diameter than the anti-winding cylindrical body 32 protrudes from the circular plate 34 inside the anti-winding cylindrical body 32, and this winding is prevented. An anti-winding cylindrical body 32b is inscribed from the board 19 on the weeding blade 20 side in contact with the anti-sticking cylindrical body 32a, and the fixed-side anti-winding cylindrical body 32a and the rotation-side anti-winding cylindrical body 32b are wrapped together. Thus, the wrapping of the grass around the drive shaft 17 is prevented. In short, by forming a double structure with the outer large-diameter wrapping prevention cylinder and the inner small-diameter wrapping prevention cylinder, a further wrapping prevention effect can be expected.

  In the embodiment shown in FIGS. 15 and 16, the blade portions C <b> 1 and C <b> 2 are provided on both surfaces of the weed plate 20 in the rotational direction. If the cutting performance of the blade C1 on one side is reduced due to wear or damage due to long-term use, if the blade weeds on the left and right sides sandwiching the chain case are used interchangeably, the blade C2 on the other side It is possible to act, and the life of the blade can be maintained for a long time.

  A traveling vehicle equipped with the weeding device 8 and the water spraying device 7 of the above example is driven along the ridge to start the weeding work. The water tank 9 is filled with water in advance, and the boom (the right-hand spray boom in the example of FIG. 2) 11R on the side of the next stroke of the spray boom 11 is projected to the work posture at the start of the work, and the center. The spraying boom 11C is also sprayed to drive the pump 10 and perform weeding work while sprinkling water. Therefore, water is sprayed on the upper surface of the cocoon immediately before the aircraft and the soybean crop grown in the next process, and is appropriately moisturized. Thereafter, the aircraft passes, and the weeding device 8 performs weeding of the furrows and weeding of the upper surface of the furrows. During the weeding of the weeding device 8, if the machine body or a part of the frame of the weeding machine comes into contact with the growing soybean, the shea will bounce and easily shed, but the moisture spraying device 6 spreads moisture before weeding in advance. Thus, the soybean sheath retains moisture, and there is no risk of shedding even if the weeding device 8 or a part of the machine body comes into contact with the soybean crop during the weeding operation.

  In the above embodiment, the weeding device 8 is configured to move along the furrows between the left and right crop rows and weed while excavating the top soil of the furrow grooves, but is not limited to this, for example, rotating The disc may be a weeding device that rotates around the vertical axis along the upper surface of the bowl, or any other configuration.

  Moreover, since it is a reciprocating weeding operation form to form a work stroke, water spraying by the water spraying device 6 can be performed in the range of the next stroke, and weeding after watering compared to the relationship arranged before and after the aircraft. The time until work can be ensured, and the moisture retention effect can be enhanced by lengthening the time for keeping moisture.

  The embodiment shown in FIG. 17 shows a configuration example in which the startability of the gasoline engine is improved. When stored for a long period of time, the fuel in the carburetor evaporates, and even if the fuel is sucked up by a pump attached to the engine, the fuel in the pipe is lowered and cannot be sucked up. As a countermeasure, in this example, a cap that closes the supply port 41 of the fuel tank 40 is removed, and a simple manual pump (bellows-type hand pump) 42 is screwed into the supply port 41. Then, the pump is pushed by hand, and the fuel is pushed up through the pipe 43 to the gasoline standard fuel pump. Thereafter, when the engine is started with a key, an engine that does not start is also started for long-term storage.
