  In recent years, in order to improve the operating environment of agricultural tractors, various ideas have been made to improve the comfort and comfort of the driver's seat. In order to continue outdoor work comfortably for a long time, frequent hydration is indispensable. Therefore, as shown in Patent Document 2, a cup holder (including a plastic bottle holder) is placed around the driver's seat. It has been proposed to install in a range that can be reached.

  However, in the agricultural tractor of Patent Document 1, since the cup holder is formed on the armrest portion of the driver's seat, there is a possibility that the PET bottle inserted into the cup holder may interfere with the operation of turning back. In addition, when holding a drink cup, etc., the body drinks are struck on the seat surface of the driver's seat, nearby operation levers, and various switches by bumping the body when riding, sitting, getting off, or vibration of the car body while driving There is a possibility of scattering.

  In addition, if a deep cup holder is formed to increase the stability of the PET bottle assuming large body vibration, the height of the side panel will increase and the height of the driver's seat will increase as the bottom of the cup holder protrudes downward. It becomes out of balance. In addition, with a deep cup holder, a shallow paper cup or the like falls down and cannot be taken out, and when a key, coins, screws, or the like are inserted, a special tool is required for taking it out.

  An object of the present invention is to provide an agricultural tractor in which a side panel does not have a very high height even when a deep cup holder is formed, and cups, bottles, and small items can be easily taken out as a deep cup holder.

And a recess (20) that can accommodate a drink bottle or the like (21).

  The agricultural tractor according to claim 2 is the agricultural tractor according to claim 1, wherein the side panel (16) is made of an integrally molded product of synthetic resin, and the recess (20) is made of a cylindrical shape having a bottom surface. It is.

  In addition, although the code | symbol in the said parenthesis is for contrast with drawing, it has no influence on a claim by this.

  According to the first aspect of the present invention, since the concave portion constituting the drink holder is formed on the front inclined surface of the side panel, the bottle accommodated in the concave portion is greatly exposed on the front side and above the concave portion. Since it protrudes, it is possible to easily take out the bottle and store it in the recess in the natural state during operation and without visual confirmation, and the bottle is stored in the recess. However, the bottle holder does not interfere with operations such as raising and lowering the work machine by the operating means by the operator and handle operation, and a bottle holder with good handleability can be provided.

  According to the second aspect of the present invention, the concave portion is easily formed in the side panel made of an integrally molded product, is formed in a cylindrical shape having a bottom surface, and is formed in a front downward inclined surface. The depth of the bottom of the part is shallow, and it is possible to insert small screw parts or mobile phones that are necessary when installing work equipment, etc., and to easily remove them, and to improve the handling of various storage items. To do.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  The side panel 16 is attached to the fender portion 13 on the right side in the traveling direction, and an operating lever and setting switches (not shown) are arranged on the fender portion 13 on the left side in the traveling direction, which also serves as an armrest on the left side of the driver's seat 12. Another side panel (not shown) is arranged.

<Side panel>
2 is an explanatory diagram of a state in which an operator seated on the driver's seat operates the side panel, FIG. 3 is a perspective view of the side panel viewed from the driver's seat side, and FIG. 4 is a plan view of the side panel viewed from above. Is a front view of the side panel as viewed from the front, FIG. 6 is a rear view of the side panel as viewed from the rear, FIG. 7 is a side view of the side panel as viewed from the outside, and FIG. FIG.

  As shown in FIG. 2, the side panel 16 on the right side in the traveling direction has an elevation control lever (position lever) 17 disposed at substantially the same height as the top of the fender portion 13, and various setting switches are arranged behind the elevation control lever 17. A retractable switch box 19 is disposed. The switch box 19 is provided with other switches that are used for setting and operation control necessary for driving and operating the traveling machine body 10 (FIG. 1) but are not so frequently used.

  The side panel 16 is prepared as an assembly unit in which wiring is completed by assembling a rotation mechanism of the elevation control lever 17, a position detection switch of the elevation control lever 17, various switches in the switch box 19, and the like.

  The inclined surface 16a on the front side of the side panel 16 is formed with a recess 20 in which a drink cup 21 can be inserted and held. The recess 20 can also store PET bottles and other items other than the drink cup 21. It is.

  As shown in FIG. 3, the driver's seat side of the side panel 16 is fixed to the standing surface of the fender portion 13 (FIG. 1) with screws at the attachment portions 16m and 16n. A lever guide 15 swelled in a semi-cylindrical shape is formed at the base portion of the lift control lever 17 in the side panel 16, and the top of the lever guide 15 and the switch box 19 are connected at substantially the same height to form a rib-shaped armrest. A portion 18 is formed.

  Further, a tilling depth setting dial 23 that is operated together with the elevation control lever 17 is disposed in an inwardly-facing recess 24 surrounded by the rib-shaped armrest portion 18, the lever guide 15, and the switch box 19. A partition wall portion 16 b is provided between the switch box 19 and the recess 24 so that soil and moisture accumulated in the recess 24 do not enter the switch box 19. The standing wall surfaces 16e and 16f surrounding the recess 24 abut against the back of the hand and the back of the finger when operating the plowing depth setting dial 23, so that the plowing depth setting dial 23 can be operated reliably even during heavy running. .

  On the driver's seat side of the side panel 16, an inclined portion 16 c that secures room for movement of the operator 11 is formed outside the driver's seat 12, so that the movement of the operator 11 turning back is not hindered.

  The lift control lever 17 is provided with a wide head 17b that can be easily gripped on the distal end side of an arm 17a that is rotatably supported. Since the base side of the head 17b is narrowed and a sufficient space is ensured between the armrest portion 18 and the lever guide 15, the elevation control lever 17 is located at any rotational position. The fingers can be easily evacuated.

  As shown in FIG. 4, the outside of the side panel 16 is fixed to the fender portion 13 (FIG. 1) using screws with attachment portions 16 i, 16 j, and 16 k. The switch box 19 can easily operate an internal setting switch (not shown) from the driver's seat side by opening the cover 19a outward with the hinge 19b as the center.

  Further, the guide groove 15a of the lever guide 15 is formed to be inclined toward the driver's seat side from the front side to the rear side, and the rod 17a of the elevating control lever 17 is moved forward along the guide groove 15a. It is pivotally supported by a pivot shaft (not shown) that is inclined to the right.

  As shown in FIG. 5, the elevation control lever 17 is located outside when the lever is tilted forward, and approaches the driver's seat when the operator 11 (FIG. 1) pulls forward. The recess 20 is formed at a position lower than the height at which the elevation control lever 17 is rotated to the lowest position on the front side.

  As shown in FIG. 6, the side panel 16 is formed by injection integral molding using ABS resin, and the outer side surface 20h of the recess 20 (FIG. 3) is a substantially cylindrical shape that ensures the inclination necessary for the die-cut taper. It is formed with an external appearance. Further, in the recess 15h of the lever guide 15 (FIG. 3), a rotation mechanism or the like (not shown) of the elevation control lever 17 is assembled.

  As shown in FIG. 7, the recess 20 is formed on the inclined surface 16 a inclined downward toward the front along the inclination of the fender portion 13 (FIG. 1), so that the rear side is deep and the front side is shallow. . Therefore, even a small 100 ml drink cup can be easily put in and out from the front side, and even an unstable 500 ml drink cup can be stably held with the side surface sandwiched. Also, since the fingers of adults reach the entire bottom of the recess 20 from the front side, when storing small items such as screws, lighters, keys, etc. in the recess 20, the hand from the front side can be used without using tools such as tweezers. Can be easily scraped off.

  In addition, the bottom position of the recess 20 is designed to be low so that when the recess 20 holds the 500 mm PET bottle, the tip of the PET bottle does not enter the interference range of the hand that operates the elevation control lever 17. ing. A large rounded step is formed at the bottom of the recess 20 to facilitate scraping and cleaning of small items along the bottom of the recess 20.

  As shown in FIG. 8, the tilling depth setting dial 23 positioned between the lever guide 15 and the switch box 19 is protected by the armrest portion 18 and the partition wall portion 16b. The elbows and hands of the operator 11 (FIG. 1) during driving and the operator 11 (FIG. 1) during driving are difficult to hit.

<Operation of the lift control lever, etc.>
As shown in FIG. 1, the elevation control lever 17 operates to raise and lower the position of a working machine (not shown) connected to the coupling device 6, and a state where the state of tilting to the front side is caused in the downward direction and the rear side. Is in the up direction. The plowing depth setting dial 23 sets the plowing depth at the time of plowing work. By setting the dial to a desired depth position according to the scale, the lifting control lever 17 is operated to land the work implement. The depth of cut into the cultivated ground can be adjusted.

  The switches stored in the switch box 19 include a lift position adjustment dial when operating the lift control lever 17 to raise the work implement, and an inclination adjustment for setting an inclination angle when automatically adjusting the work implement inclination. A dial, automatic horizontal control of a work machine, a manual changeover switch, a changeover switch of a work machine type, a setting switch of a work mode, various manual operation levers, and the like.

<Effect of this embodiment>
In the traveling machine body 10 of the present embodiment, the concave portion 20 that can be used as a drink holder is formed on the inclined surface 16a of the side panel 16, so that the bottle stored in the concave portion 20 is greatly exposed at the front side thereof and the concave portion 20 is exposed. So that the bottle can be taken out and stored in the recess 20 in a natural state during operation and without visual confirmation, and the bottle is stored in the recess 20. Even if the bottle is in the state, the bottle does not interfere with operations such as raising / lowering the work machine by the elevation control lever 17 by the operator 11 and operation of the steering 4. Accordingly, it is possible to provide a bottle holder that is easy to handle.

  Further, the concave portion 20 is easily formed in the side panel 16 made of an integrally molded product, has a cylindrical shape having a bottom surface, and is formed on the inclined surface 16a that is lowered forwardly. It is shallow, and can be used to insert small screw parts or a cellular phone that are necessary when the work machine is mounted, and can be easily taken out, and the handling of various storage items is improved.

  Further, since the concave portion 20 is disposed on the inclined surface 16a, the deep concave portion 20 can be formed with less protrusion to the lower surface of the side panel 16 than when disposed on a flat surface. Therefore, even with the recess 20 having a diameter that can accept many kinds of bottles and cups, a tall drink cup and a thin bottle can be stably held depending on the depth, and the protrusions can be held with little protrusion.

  Further, in a relatively small agricultural tractor such as the traveling machine body 10 of the present embodiment, it is difficult to mount a driver's seat with an armrest because the distance between the left and right fender portions 13 is narrow, but it also serves as an armrest. Since the side panel 16 is adopted, the posture of the operator 11 is stabilized, and stable driving and operation can be continued even when the vehicle body is greatly shaken or tilted during operation or work. Therefore, when confirming the already cultivated land and the uncultivated land by the front wheel tire traveling position at the time of adjacent tillage work, the traveling machine body 10 can be operated and operated without forcing the operator 11 to take an unreasonable posture.

  Compared with the case where the lifting grip 5 is used as an armrest, as shown in FIG. 2, since the portion where the elbow touches is wide with the switch box 19 and the partition wall portion 16 b, the feeling of pressure is small, and a long time There is no pain even if the armrest position is maintained, and the elbow is not hit when the elbow is shaken in and out. On the other hand, since the armrest portion 18 is narrow enough to be grasped by hand, when the operator 11 performs a large turn around the work, it is possible to hold the armrest portion 18 and maintain a turned posture. Therefore, even when the operator 11 turns around and confirms the work state, the operator can support the weight and can obtain a stable work posture.

  Further, even if the recessed portion 20 is provided at a position considerably lower than the knee of the sitting posture of the operator 11 and a relatively tall plastic bottle is inserted, there is no hindrance to the operation of the steering 4 and the elevation control lever 17, and the front surface Because you can see the plastic bottle in one corner of the field of view, you can rehydrate when you want without looking aside or slowing down. And since a plastic bottle is hold | maintained in the shape by which the slant half was buried in the inclination of the fender part 13, the operator 11 does not trip or get caught at the time of boarding the driver's seat 12 and getting off.

  Therefore, it is unlikely that the drink will be scattered by such an accident and the aircraft will not become dirty, and even if the drink overflows from the cup due to a large shake, the drink will only flow down to the floor and the mechanism of the lift control lever 17 and the switch box 19 does not invade. Since the bottle is held at a lower position in front of the seat surface of the driver's seat 12, the seat surface is not soiled even if a drink is spilled.

  In addition, the lift control lever 17 is located outside when it is tilted forward, and when it is pulled forward, the operator 11 (FIG. 1) moves the lift control lever 17 on a straight line toward its trunk. Because it is operated, even a small woman or an elderly person can get a lighter feeling of operation than when operating in front and back in parallel. In particular, even when the body is twisted and turned back, it can be operated easily while keeping the armrest posture without bringing the body close to the lift control lever 17. In other words, it is easy to operate the lift control lever 17 while confirming the work state behind, and an operation error and a determination error can be prevented.

  Further, the plowing depth setting dial 23 is lowered by one step from the armrest portion 18 to prevent interference from above, and further, the partition wall portion 16b prevents interference from the driver's seat 12 side. In comparison, there is no sense of incongruity at the elbows, and there is a possibility that the setting of the working depth setting dial 23 is changed due to an accidental contact of the cuffs when operating the elevating control lever 17 or when the operator 11 is seated or left. Became lower.

  Accordingly, since there is little possibility of erroneous operation due to contact, the rotational load of the tilling depth setting dial 23 can be reduced, and even a small woman or an elderly person can easily rotate and set the tilling depth. When the tilling depth setting dial 23 is gripped, the back of the hand and the back of the fingers are supported by the wall surfaces 16e and 16f and can be operated only with the hand. Compared to the case, it is possible to adjust the force more delicately, and it is possible to make a reliable and quick setting that avoids excessive rotation and reciprocation.

It is a side view of the traveling body which is one embodiment of the agricultural tractor of the present invention. It is explanatory drawing of the state which the operator seated on the driver's seat operates a side panel. It is the perspective view which looked at the side panel from the driver's seat side. It is the top view which looked at the side panel from upper direction. It is the front view which looked at the side panel from the front.
