It is a top view showing arrangement of hose H.

Next, the specific construction of the tractor-mounted remote control power sprayer of the present invention will be described with reference to the drawings. FIG.
In FIG. 2, the tractor A is supported by the front wheels 13 and 13 and the rear wheels 12 and 12. A winding machine M is attached to the front part of the tractor A, and a chemical liquid tank T and a power sprayer D are attached to the rear part of the tractor A.
The tractor A is a normal tractor equipped with a cabin K, and a driver's seat S is arranged inside the cabin K. The operation status lamp 9 of the winding machine M is arranged at a position where an operator can get on the driver's seat S and drive it.
Further, the muffler of the tractor A is an internal type disposed inside the bonnet 2.
Since the liquid supply hose 7 from the power sprayer D to the winder M does not stand on the side of the muffler, there is no possibility of contact with the muffler.

A winder insertion fork 1 is provided at the front of the tractor A.
8 is provided so that the winder M and the hose winder carriage C are lifted by the winder insertion hawk 18. Further, a tank dynamic injection support frame B is provided at the rear of the tractor A, and a chemical liquid tank T and a power sprayer D are mounted on the frame. In this way, the winding machine M is arranged in the front part, and the chemical liquid tank T and the power sprayer D are arranged in the rear part. Therefore, when the winding machine M is mounted in the rear part, the work machine in the rear part is It is possible to solve the problem that it is not possible to secure the rear view, which is caused by the height of the part becoming too high.

Further, when all the devices are arranged in the rear part or all the devices are arranged in the front part, one of the front and rear overhangs becomes too large, and the front-rear balance of the tractor A is bad. It will be. In addition, since the winding machine M is divided into the front portion and the chemical liquid tank T and the power sprayer D are divided into the rear portion, the operability of storage and the like is improved. In this way, in addition to the good front-rear balance, there is also an effect that the rear view from the driver's seat of the tractor is good, and the vehicle height is low when the tractor is stored, so that it does not interfere with the entrance to the barn. Further, since the position of the chemical liquid tank T is not so high in the rear portion of the tractor A, maintenance such as chemical liquid supply to the chemical liquid tank T is facilitated. Further, since the distance between the chemical liquid hose winder M and the tractor A becomes short, the electric wiring to the motor for driving the winder M becomes easy.

Further, as shown in FIG. 24, when the tractor A is parked along a side ridge or the like in a field such as a paddy field, a winder M is arranged in the front part, and a power sprayer D and a chemical liquid tank are arranged in the rear part. The T portion is arranged. In this state, the take-up reel 1 of the take-up machine M is pivotally supported by the reel shaft 28 in the front-rear direction.
By pulling out the hose H in the direction orthogonal to the front-back direction of the tractor-mounted remote control power sprayer, the hose H can be pulled out smoothly in the field. The hose H became easier to pull out because of the relationship between the route and the field.

As shown in FIGS. 1 and 2, the power sprayer D mounted on the rear tank dynamic spray support frame B discharges the spray liquid as pressure water, and the liquid supply hose 7 for the pressure liquid is It is necessary to cross over the tractor A, and first, it is lifted up above the cabin K along the liquid feed hose guide rod 3 protruding upward from the tank dynamic injection support frame B. Next, the liquid feed hose 7 is placed and passed above the cabin K from the liquid feed hose guide rod 3 and above the hood 2. Then, the winding machine M is reached. Further, the operation status lamp 9 and the hose feeding guide tube portion 8 are arranged above the decorative cover 29 of the winder M, and the hose H is drawn out from the hose feeding guide tube portion 8 in the field direction. It will be drawn again.

The hose feeding guide cylinder portion 8 is also arranged above the bonnet 2, and the operation status lamp 9 and the bonnet 2 are also arranged.
It is located above. If two people work, it is possible to confirm the operating status of the hose winder M from the driver's seat S of the tractor A by the operating status lamp 9. The muffler portion of the tractor A is of an internal type, and the hose H is arranged above it. As a result, the hose H is less likely to be caught by the muffler of the tractor A, and the liquid supply hose 7 and the hose H do not melt due to contact with each other due to the heat of the muffler.

Further, the hose feeding guide tube portion 8 of the hose winder M is installed above the wheels of the tractor A. As a result, when the hose H is wound up or unwound, it is not caught on the wheels or the like. By disposing the liquid supply hose 7 above the cabin K of the tractor A, the liquid supply hose 7 does not interfere when the door 11 of the cabin K is opened. Further, the obstacles on the side of the tractor A and the liquid supply hose 7 do not interfere with each other.

Further, as shown in FIG. 1, the liquid supply hose 7
The nozzle spray rod 6 forming the tip end of the tractor A is housed along the side of the tractor A.
Since the injection port spray rod 6 has a long rod shape, it interferes with the traveling of the tractor A when it is not compactly housed, but in the case of the present invention, it is wound from the bonnet 2 of the tractor A. Since a long side surface portion is generated when the portion of the machine M is added, the engagement support rod is arranged at this portion, and the injection port spray rod 6 is engaged with the engagement support rod and can be stored. As a result, the jet spray rod 6 hardly abuts and interferes with the obstacle on the side during movement.
Most of the hose H is wound on the take-up reel 1 and therefore does not become an obstacle.

Further, the winder M is configured to be mounted on a hose winder carriage C having a caster wheel 30 attached below so that the winder M can be easily moved and stored in the removed state.
Since the portion of the tank dynamic injection support frame B can be moved up and down by the hydraulic device for raising and lowering the working machine of the tractor A, the tank dynamic injection support frame B itself on which the support caster wheels 4 are mounted is moved up and down to contact the ground. It is possible to avoid this, but the winder M that is only lifted by the winder insertion hawk 18 does not have a lifting hydraulic device, so the hose winder carriage C cannot be installed as it is. Of. Therefore, the mounting frame F of the winder M and the hose winder carriage C are configured separately.

As shown in FIG. 3, the winder M mounted on the hose winder carriage C can be lifted by the winder insertion hawk 18 mounted on the front part of the tractor A. In addition, the mounting frame F is mounted on the hose winder carriage C in an inclined state. In this state, when the winder insertion hawk 18 is deeply inserted, the winder M gradually becomes horizontal and the hose winder carriage C and the mounting frame F are separated from each other.

Further, a rear bumper 12 is provided behind the tank dynamic injection support frame B so that the power sprayer D and the chemical liquid tank T are not destroyed by the collision with an obstacle when the tractor A moves backward. Is configured. Further, when a bumper is also arranged at the tip of the mounting frame F on which the winder M is mounted and the tractor A moves forward,
The take-up reel 1 is configured so as not to come into contact with an obstacle and be damaged. Further, the portion of the supply pipe 34 for supplying the chemical liquid into the chemical liquid tank T can be wound and stored in the rear portion of the tank dynamic injection support frame B.
