Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a sprayer for spraying a chemical, and particularly to a sprayer equipped with a chemical tank that can be detachably mounted on a driveable vehicle.

As shown in FIGS. 1a and 1b, the conventional chemical tank of this type of sprayer has an approximately U shape as a whole, which holds both outer walls and a bottom wall facing each other in the front and back direction of the chemical tank 1.
By means of a frame 4, a reinforcing pipe 3 that connects the upper ends of both upright parts 2a and 2b to each other and surrounds and holds the side wall of the drug tank 1 is fixed to a frame main body 2, which is framed by a pipe or the like. be removably mounted on a driveable vehicle, or
As shown in Figures a and b, a communication hole 12 is formed between the wall surfaces facing each other in the front and back direction of the drug tank 11, and upright portions 13a and 13 that can hold the facing outer wall surfaces are formed.
A frame 15 that connects the upright parts 13a and 13b of a frame main body 13 having a U-shape as a whole and is provided with a reinforcing pipe 14 penetrating the communication hole 12 makes it possible to run a vehicle (not shown). (omitted)) is removably installed.

However, in the drug tank 1 shown in FIGS. 1a and 1b, the structure of the frame 4 for mounting on a vehicle is
The reinforcing pipe 3 is bent and installed between both the upright parts 2a and 2b along the side surface of the drug tank 1, and both the upright parts 2
a, 2b must be reinforced, making the structure complicated. Also, if the reinforcing pipe 3 is eliminated, it becomes necessary to make both the upright parts 2a, 2b quite strong, making the entire frame 4 large and heavy. There is a risk that it will become a thing.

In the drug tank 11 shown in FIGS. 2a and 2b, in order to reinforce the frame 15, a reinforcing pipe 14 is inserted through the communication hole 12 of the drug tank 11 and installed between the two upright portions 13a and 13b. ,
In order to fix the drug tank 11 to the frame 15, the drug tank 11 is attached to the front or rear upright portion 13.
a or 13b and the bottom.

This idea was created in view of the above-mentioned circumstances, and its purpose was to provide a vehicle capable of running on wheels with a substantially L-shaped frame body having a front wall portion and a bottom portion, which is removably mounted on the vehicle. In a sprayer in which a drug tank and a pump capable of pumping the drug in this drug tank are mounted on the frame main body, the frame main body is connected to the front wall surface and the bottom.
A rod-shaped reinforcing member is interposed in the center between the opposing front and rear walls of the drug tank, which is formed in a letter shape and placed on the frame main body, and one end of this reinforcing member is attached to the front wall of the frame main body. The rear ends are each screwed in a watertight manner to the rear frame that forms part of the spray unit, and these and the conventional screw connections at the bottom of the tank maintain sufficient strength to secure the chemical tank and spray unit. To provide a sprayer which can be removably attached to a vehicle, and which can bring the entire center of gravity closer to the tractor side than in the conventional case, and which enables more reliable movement and spraying work.

This invention will be explained below with reference to the accompanying drawings.

FIG. 3 is an overall plan view showing a case where a boom-shaped spray unit is applied to the sprayer according to this invention. As shown in FIGS. 4 to 7, the front wall 2
A frame main body 21, which has a substantially L-shaped frame and includes a bottom portion 1a and a bottom portion 21b, is removably attached. Mounted on the frame body 21 are a drug tank 22 that stores drugs and a pump 23' that can pump the drugs. Inside the drug tank 22, a rod-shaped reinforcing material is provided between the front and rear walls 22a, 22b which face each other in the front and back, and is made by welding a plate body having screw holes 23a, 23b at both ends of a tube body. 2
3 are the front and rear walls 22a, 22 of this drug tank 22.
The front end of the reinforcing member 23 is screwed into the screw hole 23a by bolts 26 and 27 passing through holes 24 and 25, respectively, which are bored opposite to the frame body. 21, and the rear end of the reinforcing member 23 is screwed to the screw hole 23b, so that it is integrally formed at the rear of the frame body 21 with a bolt 28. They are respectively screwed onto the upper part of the rear frame 29a, which constitutes a part of the spray unit 29, via stays 30 formed of angle material. In addition, packing 31 is attached to the wall surfaces 22a and 22b surrounding both ends of the through holes 24 and 25, respectively, and the through holes 24 and 25 and the bolts 2
6 and 27 are closed in a watertight state. Further, the spray unit 29 has an upper end connected to the bolt 3.
2, each of which is screwed onto the stay 30 by two substantially parallel vertical members 29b;
A boom nozzle 29 is provided with a plurality of nozzles 29d communicating with the pump 23', and the rear frame 29a is provided with a horizontal member 29c connecting the lower ends of the boom nozzle 29.
e is attached.

Further, as shown in FIG. 8, the other one of the spray units 29 can be assembled into a frame 29'a having a U-shaped cross section by removing the bolts 28 and 32.
and the winding wheel 2 pivotally supported by this frame 29'a.
9'b, and a hose 29' wound around the winding wheel 29'b.
a nozzle 29'd attached to the tip of the nozzle c and communicated with the pump 23';
It is also possible to replace it with 9'. The spray unit 29' is attached to the frame body 21 by bolts 28 and 32 in the same way as the spray unit 29.

As described above, the sprayer according to this invention is fixed to the frame body with bolts with a reinforcing material interposed between the front and rear walls of the chemical tank, so that the chemical tank becomes stronger and the sprayer is connected to the frame body. The fixed state of the unit 29 or 29' can also be reinforced at the same time, which shortens assembly time and reduces costs compared to conventional systems that require a separate reinforcing pipe to be attached to the frame body. Is possible. In addition, the reinforcing material inside the drug tank is not molded on the wall of the drug tank, but is installed with bolts, so there is no need for molding, and the frame body is almost L-shaped, with an opening at the rear. Because of this, it is easy to mount the drug tank, and production costs can be reduced. Furthermore, since the spray unit can be easily replaced with a different type, it has the advantage of being able to carry out a wide variety of spray operations.
