DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention disperses liquids such as water and chemicals in a field, a house, etc., while automatically traveling on a plurality of furrow running paths without an operator. The present invention relates to an automatic liquid spraying device.

[0002]

2. Description of the Related Art The prior art includes, for example, Japanese Utility Model 2-2549.
There is No. 8. The self-propelled spraying vehicle shown here runs directly on the ground between groove-shaped ridges, and a laterally moving truck is provided with a gutter-shaped guideway so that the self-propelled spreading vehicle can be mounted. ing. An auxiliary path having a gutter shape and a fan-shaped bottom is provided at the tip of the guide path, so that movement between the ridges of the self-propelled spreader and the laterally moving carriage is smooth.

[0003]

However, when the field is a nursery, for example, the ridges are not grooved, and in this case, rails for running the self-propelled spreader are required. Therefore, naturally, the guide path on the laterally moving carriage also has a rail shape. In this case, if the stop position of the laterally moving vehicle is displaced from the predetermined position, the traveling path (rail) provided in the ridge and the guideway on the laterally moving vehicle do not overlap well, and the self-propelled spreader truck is disengaged from the laterally moving vehicle. There is a risk of derailment when moving between the mobile trolley and the furrow running path.

[0004]

The present invention uses the following means to solve the above problems. At the end of the rail-shaped guide path 10 for mounting the self-propelled spreader A on the laterally moving carriage B, a wide-mouthed truck rail guide portion 11 is attached, and at the same time, at the tip of the ridge-shaped travel path C, a wide-mouthed shape is also provided. Is mounted. The wheels 13 to 16 of the self-propelled spreader A have wheel guides 17.
Is provided.

[0005]

[Operation] If the stop position of the laterally moving cart B is shifted,
The right front wheel 13 of the self-propelled spreader A descending from the laterally moving cart B hits the inner side of the rail 12a of the traveling path rail guide section 12 of the furrow traveling path C as shown in FIG. The self-propelled spreader A is guided on the rail 12a to the ridge running path C. When the self-propelled spreader A rides on the laterally moving cart B, the left rear wheel 16 is moved to the rail 11b of the bogie rail guide 11 of the laterally moving cart B.
, And guides the wheels 16 on the rails 11b to move the self-propelled spreader A on the guide path 1 on the laterally moving carriage B.
Lead to zero. In this way, the self-propelled spreader A does not derail, and the movement between the laterally moving carriage B and the furrow running path C is performed smoothly.

[0006]

Next, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing the configuration of the entire automatic liquid spraying apparatus. The self-propelled spreader A is mounted on the laterally moving cart B, moves on the connecting path D, and stops at the entrance of the furrow running path C. The traveling of the laterally moving cart B is caused by being pulled by the wire 3 from the winch 1. However, the signal of starting or stopping the traveling is transmitted from the transmitter 4 of the laterally moving cart B to the receiver of the winch 1. Since the receiving operation is performed by the receiving device 2, no manpower is required for the winding operation of the wire 3.

[0007] The self-propelled spreader A, which gets off from the laterally moving carriage B stopped at the stop position, travels forward on the furrow running path C while spraying, and stands at the end point of the furrow running path C. The self-propelled spreader A (not shown)
The self-propelled spreader A starts reverse running when the bumper attached to the front portion hits. Sprinkling and spraying are also possible at this time.

The self-propelled spraying vehicle A, which has finished watering and spraying on one furrow running path, rides on the laterally moving vehicle B again, and the laterally moving vehicle B moves to the next stop position. To check the stop position, a stop position detecting plate 6 is provided at a stop position in the communication path D, and a pusher (not shown) projecting from a lower portion of the laterally moving carriage B comes into contact with the stop position detection plate 6. As a result, the limit switch built in the laterally moving truck B operates, and a stop signal is transmitted from the transmitter 3 to the receiver 2 to stop the laterally moving truck B at the stop position. Performs spraying work again on the furrow running path C.

The self-propelled spraying vehicle A pulls the spray hose 9 from the tank 7 through the moving jet 8 and the laterally moving cart B. Although the self-propelled sprayer A in FIG. 1 has a built-in device for winding the spray hose 9 when the vehicle is moving backward, in the case of the small self-propelled sprayer A, the spray hose 9 is wound up. An automatic hose winder is installed near the dynamic jet.

The present invention relates to a guideway 10 attached to the laterally moving carriage B in the automatic liquid spraying apparatus having the above-mentioned structure.
In addition, the present invention relates to the configuration of the rail guide portions provided on the furrow running path C, which will be described below with reference to FIGS. FIG. 2 is a perspective view of the lateral moving cart B. A rail-shaped guideway 10 for mounting the self-propelled spreader A is provided on the laterally moving carriage B, and a leading end thereof forms a wide-mouthed carriage rail guide section 11.

FIG. 3 is a top view in the case where the laterally moving carriage B is accurately stopped at the stop position. The leading end of the furrow traveling path C on the side of the communication path D is a wide-mouthed traveling path rail guide portion 12.
It has become. When the laterally moving cart B stops, the bogie rail guide portion 11 overlaps the traveling path rail guide portion 12, and the self-propelled spreader A travels between the laterally moving cart B and the furrow. Movement between the roads C is enabled. Guides 17 are provided on the wheels 13 to 16 of the self-propelled spreader A to prevent the self-propelled spreader A from derailing on the rails.

The reason why the bogie rail guide portion 11 and the furrow running path C are wide-mouthed is to prevent the self-propelled spreader A from derailing when the stop position of the laterally moving bogie B is shifted. That's why. FIG. 4 is a top view when the stop position of the laterally moving cart B is shifted. Explaining with reference to this figure, the self-propelled spreader A getting off the laterally moving cart B
Of the right front wheel 13 of the rail 1
2a, and the wheels 13
On the rail, and the self-propelled spreader A is moved along the furrow running path C.
It leads you up. When the self-propelled spreader A finishes the spraying operation and moves backward, the left rear wheel 16 of the self-propelled spreader A hits the rail 11b of the bogie rail guide portion and runs up. Run the spreader A on the guideway 10
Leads to In this way, the self-propelled spreader A can smoothly move between the laterally moving carriage B and the ridge running path C without derailing.

[0013]

As described above, the present invention has the following advantages. In other words, the self-propelled spreader A can move from the laterally moving vehicle B to the furrow traveling path C even if the laterally moving vehicle B does not stop exactly at the stop position.
When the vehicle moves on to the vehicle, or when riding on the laterally moving carriage B from the furrow running path C, the vehicle can move smoothly without derailing.
