Advantages and advantages of the present invention will be more apparent from the following detailed description based on the accompanying drawings.

1 is a perspective view of a first self-propelled sprayer according to the present invention, which is configured around the caterpillar vehicle 1. This caterpillar vehicle (1) is configured such that the turret (7) on which the caterpillar (3) and the driver's seat (5) mounted for driving can be rotatable in the vehicle body. In the self-propelled sprayer of the present embodiment, since such a known technique is applied as it is, a detailed description thereof will be omitted.

This self-propelled sprayer has a first truss beam 9, a truss column 11, a first cable 13, and a plurality of sprays to spray liquid pesticides or fertilizers while driving on its own power, that is, the caterpillar vehicle 1. The nozzles 15 and 15 and the storage tank 17 are main components.

The first truss beam 9 is installed in a cantilever shape on one side of the turret 7, and when the caterpillar vehicle 1 runs on a road outside the pavement (not shown, hereinafter omitted), the first truss beam 9 is placed on the crop in the pavement. Have enough length to pass through a significant range. That is, the first truss beam (9), when the road is formed on the outer side of the square pavement, should be formed in a length that can spray pesticides and fertilizer at least half the width of the pavement in one run. It is possible to prevent the generation of the spreading area.

Since the first truss beam 9 has a considerable length, a deflection phenomenon due to gravity occurs at its tip. In order to prevent this deflection phenomenon, a truss column 11 is installed in the turret 7 on which the first truss beam 9 is mounted, and the truss column 11 and the first truss beam 9 are connected to the first cable. (13) are connected to each other.

The truss column 11 is installed in the form of a column on the turret 7, and is installed in the vertical direction on the turret 7 in FIG. 1, but the weight of the first truss beam 9 and the caterpillar vehicle ( It may be installed in an inclined state in which the upper end thereof is flipped in the opposite direction of the first truss beam 9 by the correlation with the weight of 1).

The first cable 13 connecting the truss column 11 and the first truss beam 9 may be fixedly connected to each of the front ends thereof simply as shown in FIG. 1 (a), but the first truss One end may be fixedly connected to the distal end of the beam 9 and the other end may be fixedly connected to the truss column 11 after a predetermined distance inward of the first truss beam 9 (b). In the latter case (b), the first truss beam (9) is more stable than in the case of the former (a) because the middle portion of the first truss beam (9) can be more prevented from bending in the direction of gravity. I can support you in a state.

In the first truss beam 9 which maintains such a beam state, many spray nozzles 15 and 15 are arrange | positioned, maintaining the constant space | interval with the adjacent nozzle 15 and 15. As shown in FIG. The nozzles 15 and 15 are stretched by a predetermined length on the first truss beam 9 so that the pesticides or fertilizers in the liquid state can be intensively sprayed on the stub portion of the crops while passing through the crops as shown in FIG. 2. Hanged down

The spray nozzles 15 and 15 are attached to the first truss beam 9 via hooks 19 to facilitate installation and removal. The hook 19 is hooked on the upper side of the connecting members 23 and 23 for connecting the hose 21 supplied with the liquid pesticide or fertilizer. The spray nozzles 15 and 15 provided below the connecting members 23 and 23 are upwardly inclined in the spray direction thereof. The direction of the spray nozzles 15 and 15 allows the pesticides and fertilizers to be sprayed upward from the bottom of the stubble of the crop so that more pests can be concentrated in the concentrated areas.

Liquid pesticides and fertilizers sprayed by the spray nozzles 15 and 15 are stored in the storage tank 17, and are pumped by the operation of a high pressure pump (not shown). As such, the connection and configuration of the high pressure pump for pumping the pesticide and the fertilizer in the liquid state from the storage tank 17 to the spray nozzles 15 and 15 can be applied to a known technique as it will not be described in detail.

First, the caterpillar vehicle 1 travels along a road provided outside the pavement F, and the first truss beam 9 is located on the pavement F while traveling in the traveling direction of the caterpillar vehicle 1. .

At this time, since the caterpillar vehicle 1 does not enter the pavement F, the first truss beam 9 should be formed to be longer than the length corresponding to the longest distance of the pavement F surrounded by the road. As it proceeds, the entire range of the packaging (F) can be completely sprayed with liquid pesticides and fertilizers.

In addition, the first cable 13 connects the first truss beam 9 to the truss column 11 to prevent the first truss beam 9 from sagging in the direction of gravity. Therefore, since the first truss beam 9 maintains a constant height with the crop, the spray position of the spray nozzle 15 with respect to the crop is also maintained at a constant height.

That is, the spray nozzles 15 and 15 provided in the first truss 9 are run down to the crop P of the package F as shown in FIG. 3. In accordance with the continuous farming (P) while continuing to spray the pesticide or fertilizer in the liquid state that is pumped to the hose (21).

In the case of pesticides, the pesticides can be maximized on the stubble of the crops (P) where the pests are concentrated, and the pest interference effect can be maximized compared to the spraying on the crops (P). In the case of fertilizers, nutrients are absorbed in the vicinity of the roots, so that the effect of fertilization can be improved as in the case of pesticides.

On the other hand, when the first truss beam 9 is formed to have a length of several tens of meters or more, its own weight is considerable, so that the counter balance 25 corresponding to the weight of the first truss beam 9 is replaced by the first truss beam 9.
