Description

  The present invention relates to an agricultural machine. In particular, the present invention relates to an agricultural machine with improved visibility from the rear.

  BACKGROUND ART Agricultural machines that are pulled by being connected to a traveling machine body such as a tractor include an agricultural machine that can change a wide expanded state and a folded state. Originally, such a foldable farm work machine is folded and pulled by a tractor when traveling between farm fields.

  However, because it is troublesome to fold one by one, the worker may travel with the apron or the like of the agricultural machine spread while moving between the farm fields. If the vehicle is moved in such a wide unfolded state, it may be dangerous for the following vehicle, especially at night, so a safer agricultural machine is desired.

  Further, conventionally, at night and the like, there has been a problem that it is difficult to directly recognize whether a work machine that is running or stopped in front is spreading or folded.

  In addition, there was a problem that it was difficult to confirm whether the farm machine was forgotten to be folded from a remote place at night.

  Here, a reflective surface is formed on the surface part at a predetermined position such as a cautionary part on the work of the agricultural machine or a position confirmation part on the movement, and information such as a danger or a warning is notified to the reflective surface. There is an agricultural machine with a sticker displaying a notice sign (Patent Document 1).

  However, this invention uses both a safety sign sticker and a reflective sticker, and does not focus on the width of a wide agricultural work machine that can be folded.

  Further, Patent Document 1 discloses a sticker, and it is impossible to grasp the size of the agricultural machine even if it is simply affixed to a cautionary part or a position confirmation part on movement or viewed from behind. . Moreover, even if the character which calls attention is described in the sticker of patent document 1, description cannot be confirmed unless it approaches at night etc. considerably.

It is a photograph of the agricultural machine concerning one example of the present invention.

  In view of the above-mentioned problems, the present inventors have invented the agricultural machine according to the present invention. Therefore, hereinafter, an agricultural machine according to an embodiment of the present invention will be described in detail with reference to the drawings. However, the working machine of the present invention can be implemented in many different modes, and is not construed as being limited to the description of the embodiments described below. In addition, the dimensional ratio in the drawing may be different from the actual ratio for convenience of explanation, or a part of the configuration may be omitted from the drawing. In the drawings referred to in this embodiment, the same portions or portions having similar functions are denoted by the same reference numerals, and repetitive description thereof is omitted.

(Embodiment 1)
With reference to FIG. 1 and FIG. 2, the agricultural machine which concerns on one Embodiment of this invention is demonstrated. First, the agricultural working machine 10 of FIG. 1 is a tilling work machine that is attached to the rear part of the traveling machine body and advances as the traveling machine body advances while rotating the tilling rotor to plow the farm field.

  This tilling work machine 10 is divided into a center part 5 and a left and right work machine parts 6L and 6R that are slightly wider than the interval W of the tire T of the tractor. The inner end portions of the machine parts 6L and 6R are connected to each other so as to be able to rotate about 180 ° by the rotation shafts, and can be folded so that the back surface of the central part 5 and the back surfaces of the left and right work machine parts 6L and 6R are overlapped. Yes. As shown in FIG. 1, the lengths of the left and right work machine parts 6L and 6R are approximately halved with respect to the length of the central part 5. The work machine parts 6L, 6R are symmetrical and have substantially the same configuration. In the farm work machine 10, the work machine parts 6L and 6R correspond to wide members of the work part.

  Such a tillage working machine is wider than the lateral width of the traveling machine body in the working state, and can be folded. That is, a working part larger than the width of the tractor can be secured by unfolding during work (hereinafter, the unfolded state is referred to as the unfolded state). On the other hand, by enabling folding, it is possible to move between fields. Smaller and easier to move. Of course, it is also possible to work in a folded state. FIG. 2 shows the tillage working machine in a folded state.

  In the present embodiment, the reflecting material is pasted on the portion including both ends of the wide member so as to be substantially line symmetrical. By pasting the reflective material on the portion including both ends of the wide member, it is possible to determine how wide the working machine has.

  The portion including both ends of the wide member needs to be affixed at a position where it can be understood that the working machine is in the unfolded state at least, but it does not necessarily have to include both ends as points.

  Although it does not need to be substantially line symmetric, the design is improved by making it substantially line symmetric. By improving the design, the farm machine becomes more attractive and becomes a farm machine that is motivated to operate. The reason why it is substantially line symmetric is that, for example, when the reflective material includes characters, it cannot be interpreted as being completely line symmetric.

  It is desirable that the reflecting material is not stuck in pieces, but is continuously stuck so as to include both ends of the wide member. This makes it possible to intuitively give the impression that “a wide member exists” when viewed from behind. In particular, in the present embodiment, it is possible to intuitively understand that a wide member exists in combination with a later-described highly reflective region reflecting light and floating.

  On the other hand, when a so-called sticker having a rectangular shape is affixed in pieces, it cannot be determined whether it is a wide member or a plurality of vehicles when viewed from behind. In addition, when a so-called sticker is affixed in pieces and characters are written on the sticker, it is not possible to confirm the description unless they are very close.

  FIG. 3 shows the affixing position 8R and the affixing position 8L, which are positions where affixing is desired on the apron member, which is a wide member in the tilling work machine 10.

  Since the reflective material used in the present embodiment can be formed of a deformable material such as a synthetic resin film, it can be pasted even if the wide member has a curvature. Each of them can be adhered to each other with certainty in a predetermined position. For example, it can be bonded to a central apron and left and right aprons which are wide members.

  The reflective material used in this embodiment includes a high reflection region and a low reflection region having a lower reflectance than the high reflection region. The highly reflective area appears to reflect and float when illuminated by light, so it is possible to make the characters, figures, patterns, etc. appear to be raised by making the parts of characters, figures, patterns, etc., highly reflective areas. It becomes.

  There is a difference in the cross-sectional structure between the high reflection region and the low reflection region. The cross-sectional structure of the highly reflective region is a structure having an adhesive layer, a reflective layer, and a transparent layer. The cross-sectional structure of the low reflection region is a structure having an adhesive layer, a reflective layer, an opaque layer, and a transparent layer. In the low reflection region, the opaque layer is interposed to make it difficult for light to be reflected.

  Here, a general adhesive substance can be used for the adhesion layer. For example, rubber-based, acrylic-based, silicon-based, urethane-based, polyamide-based, and polyester-based pressure-sensitive adhesives can be used. As the reflective layer, a resin containing a lens or glass beads, a prism, or the like can be used. Various opaque printing paints can be used as the opaque layer. As the transparent layer, polyethylene terephthalate (PET), polypropylene (PP), or the like can be used. In addition, a film layer or the like may be used on the transparent layer in order to increase durability. For example, polyethylene terephthalate (PET), polypropylene (PP), etc. can be used.

  And the color of the transparent layer of a low reflection area | region may be the same as the color (For example, the color of a sticking location, a main body color, etc.) of the predetermined location of an agricultural machine. By being the same as the color of the portion to be affixed, the low reflection area becomes assimilated with the main body color and becomes inconspicuous, and the high reflection area can be made more noticeable. For example, when a red color is used as the main body color, the white color of the high reflection region can be made conspicuous by using the low reflection region as a red color and white as the high reflection region.

  In addition, two or more different colors can be used for the high reflection region. For example, by using blue and white as the high reflection region, it is possible to make blue and white appear to be raised with respect to red in the main body and the low reflection region.

  By attaching a reflective material to a wide member, the presence of the wide member can be intuitively confirmed by reflection of light from a distance even in the dark, and safety can be improved.

  By sticking on the leveling plate part, it is possible to confirm from a distance whether the tillage work machine is folded or spread even in the dark, and safety and convenience can be improved.

  Since the letters are raised, the design is improved and the willingness to use can be improved.

Example 1
4A and 4B are photographs of a tillage working machine according to an embodiment of the present invention. In FIG. 4, the area of the tillage work machine is surrounded by a white frame. From the photograph of FIG. 4, it was found that in this example, it can be visually recognized by illuminating the light even at night. At this time, it was possible to determine whether it was in a deployed state or a folded state from a distance. It was also found that the design of characters that float in the dark improves.

  Therefore, according to the present invention, by applying a reflective material to a wide member, the presence of the wide member can be intuitively confirmed by reflection of light from a distance even in the dark, and safety can be improved. Moreover, according to this invention, by sticking on a leveling board part, even if it is dark, it can be confirmed whether the agricultural machine is folded or spread from a distance, and safety and convenience are improved. Further, according to the present invention, the design is improved because the characters are lifted.
