Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a chemical spraying vehicle such as a speed sprayer, and specifically relates to a structure for mounting a suction hose on a chemical dispersing vehicle.

[Conventional technology]

FIGS. 8 and 9 are a side view and a schematic cross-sectional view of the chemical tank portion of the speed sprayer 10 equipped with a conventional suction hose attachment structure. The speed sprayer 10 includes a truck 16 that is supported by front tires 12 and rear tires 14 and is self-propelled.A driver's seat 18, an engine room 20, a chemical tank 22, a jet head 24, and a blower 26 are installed on the top of the truck 16. installed or arranged. The lower part of one side of the chemical tank 22 is recessed inward in the width direction of the speed sprayer 10 to form a recess 2.
8, and the recess 28 extends substantially along the circumference of the rear tire 14. Bracket 30 is
They are fixed to the drug tank 22 at appropriate intervals along the recess 28 and project toward the bottom of the recess 28 . The tip of the suction hose 32 is submerged in a water source or the like, and water sucked in by a pump in the engine room 20 is introduced into the drug tank 22 via a hose (not shown). The suction hose 32 is placed on the bracket 30 when not in use.

[Problem that the invention attempts to solve]

The problems with the conventional mounting structure of the suction hose are as follows.

(1) Since the suction hose 32 is only placed on the bracket 30, it is likely to fall off from the bracket 30 due to bouncing and vibration of the speed sprayer 10.

(2) Since the suction hose 32 is installed with the opening at its end open, mud etc. thrown up by the rear tires 14 when the speed sprayer 10 is running enters into the suction hose 32 through the opening at the end of the suction hose 32, and when water is absorbed. The mud and the like are introduced into the chemical tank 22 together with water.

(3) Mud and the like that are splashed up by the rear tire 14 and adhere to the tip of the suction hose 32 contaminate the water source when water is absorbed, and the contaminated water is introduced into the chemical tank 22.

(4) Since the suction hose 32 is exposed, stones etc. thrown up by the rear tire 14 may fall onto the suction hose 32.
If this occurs, the suction hose 32 may be damaged.

This invention aims to solve these problems.

[Means for solving problems]

The chemical solution spraying vehicle according to this invention includes a fender that covers the outside in the radial direction of the tire, a groove formed on the outer periphery of the fender that extends in the circumferential direction of the fender, into which the suction hose is inserted, and a groove from which the suction hose is inserted. The suction hose includes a locking means for preventing the suction hose from coming off, and a lid portion provided at the end of the groove to close the opening at the tip of the suction hose when the suction hose is attached to the groove.

[Effect]

The suction hose is fitted into a groove on the outer periphery of the fender, and is prevented from falling out of the groove by a locking means. Further, the tip of the suction hose is closed by a lid.

Mud, stones, etc. thrown up by the tires hit the fender, and adhesion to the intake hose and collision are avoided. Further, the lid prevents splashed mud from entering the suction hose through the opening at the end of the suction hose.

[Example] Hereinafter, the present invention will be described with reference to an example of the drawings, with reference to FIGS. 1 to 7.

FIGS. 2 and 3 are a side view and a schematic cross-sectional view of the drug tank portion of the speed sprayer 10 equipped with a suction hose attachment structure. The recess 28 is formed in the lower part of one side of the drug tank 22, and the fender 34 is disposed in the recess 28, fixed to the side of the drug tank 22, and extends radially outward of the rear tire 14 in the upper half of the rear tire 14. It's covered. The fender 34 prevents mud and stones thrown up by the rear tires 14 from going upward, that is, toward the outer circumference.

FIG. 1 is a perspective view of the fender 34. The groove 36 is formed on the outer peripheral side of the fender 34 so as to extend in the circumferential direction of the fender 34, and the suction hose 32 is inserted into the groove 36. The rear end of the groove 36 is closed by a lid 38, and a cylindrical member 40 having a predetermined length in the vertical direction is fixed to the lid 38. The diameter of the cylindrical member 40 is approximately equal to the inner diameter of the suction hose 32, and the cylindrical member 40 can be fitted into the opening at the tip of the suction hose 32. When the suction hose 32 is attached to the groove 36, the suction hose 32
The tip of is located almost in contact with the lid part 38,
The tip is closed by the lid part 38. As a result, the mud thrown up by the rear tire 14 is transferred to the suction hose 32.
Intrusion into the suction hose 32 through the opening at the tip thereof is avoided.

FIG. 4 shows a structure in which the suction hose 32 is locked into the groove 36. The depth of the groove 36 is the same as that of the suction hose 3.
2, and the width between the pair of side edges 42 as the edges on the opening side of the groove 36 is narrower than the outer diameter of the suction hose 32. The suction hose 32 has a concave groove 3
6, the diameter is elastically reduced, and after the insertion, the diameter is returned and the side edge 42 prevents it from coming off the groove 36.

FIG. 5 shows another structure for locking the suction hose 32 into the groove 36. The depth of the groove 36 is shallower than the outer diameter of the suction hose 32, and the opening width of the groove 36 is wider than the outer diameter of the suction hose 32. A pair of leaf spring members 4
4 has its proximal end fixed to the fender 34, and the concave groove 3
6 inward in the width direction in an arc shape. The pair of leaf spring members 44 are provided along the groove 36 at appropriate intervals. The suction hose 32 elastically reduces its diameter and passes through the groove 3 from the gap between the pair of leaf spring members 44.
6 and is inserted into the concave groove 36 by the plate spring member 44.
Pressed by

Figures 6 and 7 show the suction hose 3 to the groove 36.
FIG. 2 is a cross-sectional view and a plan view of still another locking structure of No. 2; The depth of the groove 36 with a U-shaped cross section is deeper than the outer diameter of the suction hose 32, the opening width of the groove 36 is approximately equal to the outer diameter of the suction hose 32, and the suction hose 32 is completely inserted into the groove 36. be sunk. Band-shaped rotating fitting 4
6 is attached to the fender 3 by a pin 48 at one end.
4, and can rotate on the opening surface of the groove 36 to open and close the opening side of the groove 36. The band-shaped rotating metal fittings 46 are provided at appropriate intervals along the groove 36, similar to the pair of leaf spring members 44 in FIG. When attaching the suction hose 32 to the concave groove 36, rotate the band-shaped rotating metal fitting 46 around the pin 48 to open the opening side of the concave groove 36, and after fitting the suction hose 32 into the concave groove 36, Rotate the rotating metal fitting 46 again to close the opening side of the groove 36.

[Effect of idea]

As described above, according to this invention, the suction hose is fitted into the groove on the outer circumferential side of the fender, and its diameter is stopped in the groove by the locking means, and the opening at the tip is closed by the lid. Therefore, the following effects can be obtained.

(1) Since the suction hose is locked in the groove by the locking means, it is possible to prevent the suction hose from falling out of the groove despite bounces, vibrations, etc. of the chemical spray vehicle.

(2) Mud and stones thrown up by the tires hit the inner periphery of the fender and are prevented from adhering to or colliding with the suction hose, thereby preventing dirt on the water source and damage to the suction hose.

(3) When the suction hose is attached to the groove, the opening at the tip of the suction hose is covered by the lid at the end of the groove, thereby preventing mud from entering the suction hose. For example, when the lid includes a cylindrical member that fits into the opening at the tip of the suction hose, the tip of the suction hose is locked to the cylindrical member, thereby preventing the tip of the suction hose from flapping. .

(4) Since the grooves are formed on the fender, the grooves can have a rib-like effect, increasing the strength (rigidity) of the fender.
