JP 2009-214877 A JP 2002-272221 A

  The tractors and rice transplanters of the prior patent documents 1 and 2 are not equipped with a function for removing dirt, and are not displayed on the surface of the display monitor during plowing work or seedling planting work. When mud is scattered, it is temporarily difficult to see the display panel, and the operator cannot obtain accurate information.

  In order to solve this problem, when mud is scattered, it is necessary for the worker to wipe the mud with a towel, etc., but it is necessary to remove the towel every time it is wiped, and the towel must be returned to its original position. There is a problem to do.

  Furthermore, if the mud contains pebbles or the like, the surface of the display panel is damaged when wiped with a towel, and the visibility of the display panel is lowered. In some cases, the display panel may need to be replaced.

  Also, when working in rainy weather, it is necessary to remove water droplets frequently, but it is necessary to place towels in a place that does not get wet with rain, and multiple towels must be prepared. There is a problem that the decline in sex becomes more serious.

  According to the first aspect of the present invention, the surface of the liquid crystal monitor (4) is transparently mounted on the operation board (3) portion of the vehicle body (2) that works on the ground while wearing the work machine (1) and traveling on the field. A wiper rail (7) (8) is provided on the outer periphery of the monitor panel (5) to slide and guide both ends of the wiper (6), and the wiper (6) is attached to the wiper rail (7). The monitor panel of the agricultural working machine is characterized in that the surface of the monitor panel (5) is cleaned by being guided and moved in (8).

  At the time of farm work operation, the work operation is performed while looking at the display part such as the liquid crystal monitor 4 of the operation board 3, but mud, dust, rainwater, etc. are easily scattered or fallen on the surface of the monitor panel 5 covering this display. When the surface of the monitor panel 5 becomes dirty, the driver guides the wiper 6 to the wiper rails 7 and 8 to reciprocate to clean mud and water adhering to the monitor panel 5. The wiper 6 has an upper end guided by the wiper rail 7 and a lower end guided by the wiper rail 8, so that the sweeping operation can be performed smoothly and quickly.

  According to a second aspect of the present invention, there is provided a stopper for locking the movement position of the wiper (6) between the side end portion of the wiper rail (7) (8) and the sliding portion of the wiper (6). 14) and a positioning device (9) are provided, and the wiper (6) after cleaning is retracted and held at the moving end of the monitor panel 5, whereby the monitor panel of the agricultural machine according to claim 1 is provided.

  As described above, the upper and lower ends of the wiper 6 are guided and moved by the wiper rails 7 and 8. Since there are stoppers 14 at the lateral ends of the wiper rails 7 and 8, the entire surface of the monitor panel 5 can be cleaned by pressing against the stoppers 14. In addition, when the wiper 6 is locked to the stopper 14, the positioning device 9 works, and even if the movement operation of the wiper 6 is released, the position of the wiper 6 is held at the retracted position of the lateral end by the positioning device 9. Thus, it does not appear by moving to the center position or the like of the monitor panel 5 and does not disturb the driver's monitor view.

Further, when the wiper 6 is moved, the lock is immediately released from the locked state by the positioning device 9 and can be quickly swept away.
According to a third aspect of the present invention, the wiper (6) is provided along the vertical direction of the surface inclination of the monitor panel (5), and a wiper side edge of the wiper (6) is provided with respect to the upper end portion. The monitor panel of the agricultural machine according to claim 1 or 2, wherein an inclined wiper edge (10) for retreating the lower end portion is formed.

  When the wiper 6 is operated, the upper and lower ends of the wiper 6 are guided by the wiper rails 7 and 8, moved in the horizontal direction, and swept at the wiper edge 10 of the wiper 6. Since the wiper edge 10 is inclined so as to recede from the upper end to the lower end, it is easy to remove the water droplets to be swept down along the inclined surface of the monitor panel 5, and the wiper 6 can be swept off. It can be done easily, quickly and effectively.

  According to a fourth aspect of the present invention, the lower edge frame (12) of the panel frame (11) that fits and holds the lower edge portion of the monitor panel (5) is inclined downward from the center portion to the left and right side edges.

  As described above, when the wiper 6 is moved laterally along the surface of the monitor panel 5 and is swept away, the muddy water flowing down the surface of the monitor panel 5 is transferred to the lower edge frame 12 at the lower side of the monitor panel 5. It flows along the lower edge frame 12 from the central portion of the lower edge frame 12 to the left and right side portions, and is guided down to the inclined edge.

  The muddy water or the like guided down to the lateral end along the inclined edge of the lower edge frame 12 is discharged out of the surface of the monitor panel 5 from the notch 13 for discharge. Thus, the muddy water or the like that is swept down to the lower edge side of the monitor panel 5 by the lateral movement of the wiper 6 is guided by the lower edge frame 12 of the panel frame 11 that is inclined downward to the outside. Discharge quickly and smoothly.

  According to the first aspect of the present invention, the lateral wiper rails 7 and 8 are provided at the upper and lower positions of the monitor panel 5, and the wiper 6 for cleaning the monitor panel 5 is provided in the space between the upper and lower wiper rails 7 and 8. When the wiper 6 is slid in the left-right direction, mud, dust, and rain that are attached to the monitor panel 5 can be easily wiped over the entire surface in the case of rainy weather. It is prevented that the property is lowered.

  In addition to the effect of the invention according to claim 1, the invention according to claim 2 is provided with the wiper rails 7, 8 by providing the stoppers 14 of the wipers 6 at the left and right ends of the wiper rails 7, 8, and the positioning device 9. Since it is possible to prevent the 8 from being moved too much and falling off the rail, the work efficiency can be improved without requiring the trouble of replacing or rewiping the wiper rails 7 and 8.

  Further, by providing a positioning device 9 that prevents the wiper 6 from moving left and right when not in use at the position closer to the center of the left and right ends of the wiper rails 7 and 8, Since the wiper 6 can be prevented from naturally moving in the left-right direction due to vibration or the like, the wiper 6 can be prevented from covering the display monitor 4 during work, and the operator can obtain accurate information. Can be improved.

  When the positioning device 9 is a clip mechanism composed of the clip hole 15 and the spring 16, the spring 16 contracts when the cleaning member is pressed against the positioning device 9, and the clip hole 15 is retracted upward and downward. Since the wiper 6 is allowed to pass through, work operability and efficiency during cleaning are improved.

Furthermore, since the grip ball 15 is in contact with the wiper 6, even if the wiper 6 is strongly applied, it is difficult to be damaged.
In addition to the effect of the invention of claim 1 or 2, the invention of claim 3 forms an inclined wiper edge 10 in which the shape of the wiper 6 is such that the lateral width becomes narrower toward the lower side. As a result, the mud and the water are moved downward, so that the mud and the water are easily dropped. In particular, in the case of water or muddy water, it becomes difficult to sink under the wiper 6.

  In addition to the effect of the invention according to any one of claims 1 to 3, the invention according to claim 4 is a lower lower edge frame of the panel frame 11 in the monitor case that covers the outer periphery of the monitor panel 5. By forming a slanted edge with a low slope from the center part to the left and right sides at 12 parts and notch parts 13 at both ends of the slanted edge, mud and water wiped off by the wiper 6 are removed from the left and right notch parts 13. Therefore, it is possible to prevent water and mud remaining on the monitor panel 5 from contaminating the monitor panel 5 again.

  Further, the lower edge frame 12 that protrudes on the transparent surface of the monitor panel 5 is formed, and the lower edge frame 12 is configured to be inclined downwardly toward the left and right sides from the left and right center part, thereby the lower edge frame of the monitor case. 12 is formed on the inclined edges that are downwardly inclined from the left and right central portions toward the left and right sides, so that the muddy water wiped off by the wiper 6 moves to the left and right sides along the inclined edges and is discharged from the notches 13 at the lower portions of the left and right ends Thus, water and mud remaining on the monitor panel 5 are prevented from adhering to the monitor panel 5 surface again.
