Embodiments specifically configured based on the above technical idea will be described below with reference to the drawings.
FIG. 1 is a plan view (a) and a side view (b) of an example of a medicine spraying vehicle to which the present invention is applied.
The medicine spraying vehicle 1 includes a centrally arranged driver seat 6 facing a steering handle 2 on a machine body supported so as to be able to run on a field by left and right front wheels 3 and 3 and left and right rear wheels 4 and 4 capable of steering the front and rear wheels. A Lopse frame 7 standing behind it, a rear-placed chemical solution tank 5 provided with a constant discharge unit, a boom 9a at the front end of the fuselage, and left and right booms 9b, 9b that can be deployed on both sides thereof are configured. . The chemical liquid tank 5 is configured in a range extending to the rear part and both side parts of the driver's seat 6, and is provided with a lid 5 a that can be opened and closed for supplying chemical liquid on the upper surface of the tank.

  The Lops frame 7 will be described in detail. As shown in FIG. 2, a side view of the airframe without description of the spreading boom and a rear view thereof shown in FIG. 3 are integrated with the left and right main frames 11, 11 constituting the airframe. The left and right seat frames 12 and 12 are provided to support the driver's seat 6, and the left and right base frames 7 a and 7 a of the lops frame 7 are attached to the left and right seat frames 12 and 12 with bolts or the like, and the driver seat 6 is ropped to the rear position. Stand up the frame 7.

  As described above, since the LOPS frame 7 is attached to the left and right seat frames 12 and 12 provided integrally with the left and right main frames 11 and 11, the ROP frame of a general work vehicle to be mounted using the rear wheel final case. Even if the structure of the airframe is not applicable to the large chemical tank 5, the rigidity of the support frame 7 can be secured without impairing the capacity of the chemical tank 5 and the detachability of the tank 5 for multipurpose use. It becomes possible. Further, a slight gap between the driver seat 6 and the chemical liquid tank 5 can be used efficiently.

  The upper part of the Lops frame 7 is composed of a square-shaped frame part 7b with a frame having a central space in the shape of a square loop, thereby minimizing the number of parts while protecting the occupant at the position close to the occupant when the aircraft falls It is possible to secure both simplicity by the score and excellent cost performance.

  The lower end portion of the saddle-shaped frame portion 7b is the height of the upper surface of the chemical liquid tank 5, and the upper end portion is formed higher than the head of the occupant. Since the rear space can be secured, the lid 5a can be opened / closed without any trouble when water is supplied to the tank 5, and a sufficient area for protecting the head of the occupant is secured and the airframe sways during traveling. Thus, the interference between the lops frame 7 and the occupant's body can be avoided. Further, by making the vehicle width direction dimension W of the saddle type frame portion 7b equal to the width dimension of the chemical liquid tank 5, it is possible to ensure occupant protection because it can be suppressed in the rollover range even if the airframe falls.

  The vertical frame portion 7b on the upper side of the lops frame 7 is supported on the left and right base portions 7a and 7a via the left and right tiltable fulcrums 7c and 7c so that it can be folded to the side of the chemical tank 5 behind the driver seat 6. By attaching the fixing pin 7d so that it can be inserted and removed, it is possible to switch between standing and folding on the upper side, ensuring occupant protection during travel, and downsizing when storing the fuselage. Further, even when the lops frame 7 is folded, the lid 5a can be opened and closed by the space of the saddle type frame portion 7b, so that the water supply operation can be performed without any trouble even when the fuselage is stored.

  The left and right retractable fulcrums 7c and 7c are thick when the saddle type frame part 7b is tilted backward by setting the vertical type frame part 7b in contact with the top surface of the chemical tank 5 so that it can be folded. Since it can be folded and supported by a general chemical tank 5 that is firmly formed of a meat resin material, a fixing device in the folding position is not required, and a simple frame-type frame is not required without a troublesome locking operation. It is possible to shift to the folded storage state by a simple operation of tilting the portion 7b onto the chemical tank 5.

  The lops frame 7 protrudes higher than the head of the occupant when the saddle-shaped frame portion 7b is expanded to the upright position, and the rear end of the chemical liquid tank 5 is folded to the upper surface of the chemical liquid tank 5. By setting the length to be within the range up to the part, it is possible to achieve both occupant protection and compact and stable storage.

(Another configuration example)
As shown in FIG. 4, a side view of the same machine body in another configuration example is shown in FIG. It is formed in a protruding length, and the saddle type frame portion 21 is protruded rearward from the rear end portion of the chemical tank 5 at the time of overpassing, etc. It is possible to prevent the liquid chemical tank from being damaged due to direct contact with the obstacle behind.

  Reflective plates 13a and 13a are provided on the upper end surface of the LOSS frame 7 (see FIGS. 2 and 3), so that the vehicle visibility when traveling with the saddle type frame portion 7b folded on the upper surface of the chemical tank 5 is achieved. In addition, the reflectors 13b and 13b are provided on the back side of the lower end of the saddle type frame portion 7b, thereby ensuring vehicle visibility from the surroundings when the saddle type frame portion 7b is erected. Thus, it is possible to make driving safe.

  Further, by configuring the width dimension W of the lops frame 7 to be larger than the maximum width dimension of the chemical liquid tank 5, it is possible to secure a lateral safety area when the airframe rolls over.

  The fixing pin 7d for restraining the left and right retractable fulcrums 7c, 7c is disposed close to the driver seat 6 by being offset to the side (the left side in the figure) while avoiding the rear surface of the driver seat 6. It is possible to avoid the interference between the fixing pin 7d attached to the lops frame 7 and the back of the occupant seated on the driver seat 6, and in the vicinity of the driver seat 6 during the folding operation of the saddle type frame portion 7b. The handling of the fixing pin 7d is facilitated, and furthermore, by providing the handle 13 on the inner side of the upper end of the lops frame 7 (see FIG. 4), it is possible to facilitate the folding operation of the vertical frame portion 7b.
