Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a three-wheeled carriage equipped with a winder such as a hose, which is used as a working carriage for spraying while traveling, for example, in a spraying operation.
[0002]
[Problems to be solved by the invention]
Conventionally, in such a three-wheeled carriage, a feeding guide such as a winding machine hose is separately installed on the carriage, and this feeding guide is separated from one of the three wheels, so that one wheel slightly changes its direction. However, there is a problem that the feeding guide does not follow and remains in the same direction, that is, the feeding guide does not move integrally with one wheel (movement to adjust the orientation), so that running resistance increases and running becomes unstable.
[0003]
[Means for Solving the Problems]
The three-wheeled carriage equipped with a winder such as a hose according to the present invention is made to solve such a problem, and one of the three wheels (running wheel) according to the direction of the feeding guide along the feeding direction of the hose. ) Face in the same direction, that is, when the feeding guide and one wheel move together, the running resistance is reduced and the running is stabilized. In other words, a three-wheeled carriage equipped with a winder such as a hose according to the present invention has a wheel on one side of the three wheels on the longitudinal axis of the carriage equipped with a winder such as a hose. Attached so as to be able to turn freely so as to be located in the rear of the traveling direction, it is attached to the vertical axis and can be rotated by a vertical bar standing at the tip of the arm and rotating with the rotation of the vertical axis A guide that guides the hose and the like that is attached to the take-up machine, and a hoist that is mounted on the dolly and drives the take-up machine to wind the hose and the like toward the base point on the ground side such as the hose. And an engine that can be moved backward .

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. 1 is a side view showing a self-propelled sprayer that runs on a three-wheel carriage, FIG. 2 is a front view of FIG. 1, FIG. 3 is a plan view showing only the three-wheel carriage of FIG. 1, and FIG. FIG. 5 is a side view of FIG.
[0005]
In the figure, reference numeral 1 denotes a cart that travels by three wheels in which a front wheel 1a is a left and right wheel and a rear wheel 1b is a single wheel, 2 is an operation handle that projects rearward of the cart 1, and 3 is an engine mounted on the rear portion of the cart 1. 4 is a spray nozzle installed in front of the carriage 1, 5 is a hose winder installed on the carriage 1, 6 is a hose that is connected to the spray nozzle 4 and wound on the hose winder 5. 7 is a vertical axis for attaching the rear wheel 1b to the carriage 1 so that the direction of the rear wheel 1b can be freely rotated, 8 is an arm attached to the vertical axis 7 and swiveling with the rotation of the vertical axis 7, and 9 is a vertical bar erected at the tip of the arm 8. Reference numeral 10 denotes a feeding guide rotatably attached to the vertical bar 9 and guides the hose 6 fed from the hose winder 5. Reference numeral 11 denotes a positioning ball plunger interposed between the inner peripheral surface of the cylindrical portion 10 a of the feeding guide 10 and the outer peripheral surface of the vertical bar 9.
[0006]
Next, the operation will be described. In the self-propelled sprayer shown in FIG. 1, the other end portion (the right end portion in the figure) of the hose 6 is connected to a ground-side power sprayer although not shown.
Then, the hose winder 5 is driven by the engine 3 to start winding up the hose 6, and when the hose 6 is tensioned with the ground-side power sprayer as a starting point, the hose 6 winds itself up. The traveling sprayer begins to move backwards. Simultaneously with this reverse movement, the chemical solution is sent from the power sprayer by the hose 6 and sprayed from the spray nozzle 4.
[0007]
In a state where the rear wheel 1b of the carriage 1 has been moved forward (in the direction of arrow 12 in FIG. 1) and stopped (the state before spraying), as shown in FIG. However, when moving backward as described above, it turns 180 degrees as shown in FIG. 4 to move backward (in the direction of arrow 13 in FIG. 4) from the vertical axis 7. Located inside (backward relative to reverse). When the direction of the rear wheel 1b is turned, the arm 8 is also turned 180 degrees to rotate the vertical bar 9, but the feeding guide 10 only moves along the hose 6 with respect to the rotation of the vertical bar 9, and the hose The guide state of 6 is maintained.
[0008]
On the contrary, even if an angle is formed between the direction of the hose 6 and the direction of the rear wheel 1b, the swing of the feeding guide 10 is directly transmitted to the rear wheel 1b via the arm 8, and the direction of the rear wheel 1b is changed. By matching the direction of the payout guide 10, that is, when the payout guide 10 and the rear wheel 1b move together, the running resistance is reduced and the running is stabilized.
[0009]
In the above description, the three-wheel carriage equipped with the hose winder 5 is shown, but the same effect can be obtained even with a three-wheel carriage equipped with a linear body winder such as an electric wire.
[0010]
【The invention's effect】
As described above, according to the present invention, one of the three wheels (running wheel) faces the same direction according to the direction of the feeding guide along the feeding direction of the hose, that is, the feeding guide and one wheel move integrally. The effect of reducing running resistance and stabilizing running is obtained.
