  A chemical tank 13 for storing a chemical solution is placed behind the driver seat 9, an operation panel (not shown) is provided on the left and right sides of the driver seat 9, and a chemical solution such as a pump on / off operation lever (not shown) is provided. Various operating tools for spraying work are provided.

  1 and 2 show a state in which the side booms 15 are stored on both side surfaces of the vehicle body 1, are inclined obliquely upward on the left and right sides of the traveling vehicle body frame 1, and the rear end portion is bent forward. As shown in FIG. 3, the boom 15 for spraying the chemical liquid sprays the chemical liquid supplied from the chemical liquid tank 13 from a large number of nozzles 15 a attached to the boom 15 spread on both the left and right sides of the traveling body frame 1.

  1 and 2 (a) show a case where the chemical tank 13 is placed on the chemical tank mounting space provided on the rear side of the traveling vehicle body frame 1 and a state where the chemical tank 13 is being lowered from the space to the ground. FIG.

In FIG. 4, the perspective view of the attachment / detachment tool of the chemical | medical solution tank of one Example used for a chemical | medical solution dispersion | distribution vehicle is shown.
The device for attaching and detaching the chemical liquid tank 13 is connected to the front and rear guide body 16 that supports the bottom surface of the chemical liquid tank 13 so as to be movable in the front-rear direction and the rear side of the front and rear guide body 16, and the chemical liquid tank is tilted rearward and lowered. This is a configuration in which an elevating guide body 17 that slides 13 up and down is a main constituent member, and the front side of the front and rear guide body 16 can be supported on the traveling vehicle body frame 1.

  In the chemical tank attaching / detaching tool shown in FIG. 4, the front / rear guide body 16 having a configuration in which a pair of front / rear guide rods 16 a, 16 b having the same length are arranged in parallel positions, and the rear end side of the front / rear guide body 16 are provided. A lifting guide 17 is connected.

  As shown in the overall side view of FIG. 1, the elevating guide body 17 has a function of sliding and moving the chemical liquid tank 13 up and down in an obliquely lowered rearward posture. The elevating guide body 17 is formed of a substantially rectangular rod in plan view, and the rear end sides of the pair of front and rear guide rods 16a and 16b having the same length are welded to the first elevating guide rod 17a on the front end side. The second lifting guide rod 17b of the lifting guide 17 is composed of two rods having the same shape, and the front ends of the second lifting guide rods 17b are welded to both ends of the first lifting guide rod 17a. . Grounding wheels 21 are respectively attached to the rear end sides of the second rod lifting guide bodies 17b. The rotating shaft of the ground ring 21 is a third lifting guide rod 17 c of the lifting guide 17. The second elevating guide rod 17b has a bent shape on the grounding wheel 21 side so that the grounding wheel 21 can be rotated on the ground.

  Further, a back support 19 is stretched between intermediate portions of the pair of second elevating guide rods 17b. The back support 19 has an inverted U-shape when viewed from the back, and is welded to the first short tube 22 that passes through the pair of second lift guide rods 17b and slides on the second lift guide rods 17b. The second short tube 23 connected is detachably mounted. The first short tube 22 is slidable through the second elevating guide rod 17b. However, when the first short tube 22 is arranged at an appropriate sliding position, the second elevating guide rod is fixed by a fixture (not shown). The first short tube 22 is fixed by tightening to 17b.

The back support 19 is a support member for preventing the chemical tank 13 from slipping down when the chemical tank 13 moves on the lift guide body 17 in the inclined position.
Further, a base portion of the chemical tank rollover regulating member 20 is welded to each first short tube 22. The chemical tank rollover restricting member 20 has a function of keeping an interval from the ground so that the chemical tank 13 does not roll over when the chemical tank 13 is inclined with respect to the horizontal.

  When the chemical tank 13 is removed from the traveling vehicle body frame 1, the chemical tank 13 is moved rearward along the front / rear guide body 16 and then lowered to the ground along the lift guide body 17. The frame 1 can be attached and detached smoothly.

  Further, as shown in FIG. 2 (b), since the front portion of the front / rear guide body 16 can be inserted into the insertion hole 1a formed in the traveling vehicle body frame 1, the front / rear guide body 16 can be easily operated and configured. The traveling body frame 1 can be supported in a detachable posture.

  Since the back support 19 for supporting the back of the chemical tank 13 is provided on the lift guide 17 and the back support 19 is slidable along the lift guide 17, the rear side of the chemical tank 13 is supported on the back. The chemical liquid tank 13 can be lowered on the ground in contact with the body 19.

  Since the roll-up restricting member 20 of the chemical tank 13 is provided on the elevation guide body 17 and the roll-down restricting member 20 is configured to be slidable together with the back support 19, the chemical tank 13 rolls over while the chemical tank 13 is moved up and down. There is no longer to do.

  In the embodiment shown in FIG. 4, both end portions of the back support 19 have a width equivalent to the back width of the chemical tank 13, and the horizontal axis (virtual axis) 24 supported by the elevating guide body 17 is the center of rotation. And can be removed from the lifting guide 17. Thus, the operator can grip the back support 19 and the back support 19 can be detached from the lifting guide 17 so that the chemical tank 13 can be easily taken out to other places.

  When the grounding wheel 21 is provided at the rear part of the lift guide body 17, the front / rear guide body 16 is removed from the traveling vehicle body frame 1, the front / rear guide body 16 removed by the operator is gripped, and the chemical solution tank is placed on the lift guide body 17. It becomes easy to move the chemical tank 13 together with the elevation guide body 17 in a state where 13 is placed.

  FIG. 2 shows an overall side view when the grounding wheel 21 is not attached to the lifting guide body 17. In this case, since there is no grounding wheel 21, the chemical solution spraying vehicle is not moved while the lower end of the second lifting guide rod 17b on the grounding side of the lifting guide 17 is in contact with the ground, and only the chemical tank 13 is lifted and guided. It is desirable to remove from the body 17.
