Description

[Detailed description of the invention] The present invention relates to a chemical sprayer for controlling disease bacteria and pests on leaf tobacco, etc., and its purpose is to accurately and easily spray the sprayed materials such as leaf tobacco at various heights. An object of the present invention is to provide a chemical spraying machine capable of spraying chemicals.

An embodiment of the present invention will be described below based on the drawings. In the drawings, reference numerals 1 and 1' indicate rinsing rods. The rinsing rods 1 and 1' are made up of a large number of short pipes removably joined together, and have both long and short pipes. It can be used in 1. Each of the short tubes is equipped with a large number of injection ports 1a facing in one direction, which can be opened and closed at regular intervals.

The above-mentioned rinsing rods 1 and 1' are fixed to support rods 3 and 3', and these support rods 3 and 3' are rotatably pivoted to both lower ends of an attachment a attached to a substantially gate-shaped vehicle body A that straddles the ridge. Further, push and pull rods 2 and 2' are connected to the support rods 3 and 3', and are composed of horizontal rods 2a and 2a' and vertical rods 2b and 2b', which are connected to a hydraulic push and pull device A to be described later. .

When this hydraulic push/pull device (a) is operated, the push/pull rods 2, 2' are pushed and pulled, causing the support rods 3, 3' to turn in half, thereby changing the direction of the washing rods 1, 1' horizontally or vertically.

That is, a hydraulic push/pull device (a) such as a hydraulic cylinder is installed in the center of the upper part of the attachment (a), and this is connected to a lever 4 that is pivotally connected to the attachment (a). Connect one end to each other.

Next, with the other ends of both horizontal rods 2 a and 2 a' facing in opposite directions, the V
It is connected to one end of the character-shaped direction changing pieces 5, 5', and vertical rods 2b, 2b' are suspended from the other ends of the direction changing pieces 5, 5', respectively.

Further, transfer levers 6.6' are symmetrically arranged and connected to the lower ends of the left and right vertical rods 2b, 2b'.
Support rods 3, 3' are fixed to the lower ends of the horizontal rods 2a, 2a', vertical rods 2b,
2 b' to the rinsing rods 1 and 1', and the rod 1
, 1' from horizontal to vertical or in the opposite direction (
Figures 2 and 3).

In addition, inject the chemical solution into the above-mentioned rinsing rods 1 and 1' and connect each spout 1.
In order to eject the chemical liquid from a..., a hydraulic pump 8 is connected via a pipe to the chemical liquid tank 7 mounted on the vehicle body A.
The hydraulic pump 8 and the hydraulic push/pull device A are connected by a pipe.

9 is a prime mover for driving a hydraulic pump; 10 and 10 are chemical hoses; 11 is a sealed driver protection body; 12 is a driver's seat; and 13 is a hydraulically driven fan connected to the hydraulic pump 8 through a pipe 14 and operated simultaneously with chemical spraying. It is.

Figure 1 shows a car body A before installing chemical dispersion devices such as irrigation rods 1 and 1', and this car body A travels by hydraulically moving left and right rubber tracks 15 and 15'. In addition, by attaching working machines to this vehicle body A, such as inter-tilling soil crushing, soil destruction disinfection, edging, mulching, transplanting, earth damming, coring, harvesting, branch rooting, etc. Each task can be performed.

The usage of the chemical sprayer of the present invention is explained below. First, in order to spray chemicals on objects with low stem height, operate the hydraulic push/pull device A to move the left and right irrigation pipes 1 and 1' horizontally. The spout ports 1a, la, etc. are held and positioned above the object to be sprayed.
. . . is opened, and the chemical is sprayed while traveling on the material to be sprayed, which is planted in many rows.

In addition, in order to spray the material to be sprayed with tall stems, operate the hydraulic push/pull device A again to move the left and right irrigation rods 1, 1' to their injection ports 1a and 1'.
Flip it halfway in the opposite direction so that it faces each other, stand it up vertically, and spray the chemical from both left and right sides of the object to be sprayed.

In addition, at this time, the rinsing rods 1, 1 protruding from the upper end of the material to be sprayed are
Remove the upper part of the rinsing rod 1' and adjust it to an appropriate length, and open all the injection ports 1a of the rinsing rods 1 and 1' so that the chemical is evenly sprayed on the material to be sprayed. Do it like this.

As mentioned above, the chemical spraying machine of the present invention is equipped with a rinsing rod having a large number of nozzles on each leg of the roughly gate-shaped body that straddles the ridges so that it can be moved horizontally and vertically, and the rinsing rod is pushed and pulled. The washing rod is connected to a hydraulic push-pull device through a rod, and the washing rod is horizontally and
Since the rinsing rods are provided so as to be freely changeable in the vertical direction, the left and right rinsing rods can be easily switched horizontally or vertically by operating the hydraulic push/pull device.

In addition, the objects to be sprayed at various heights can be sprayed from above or from the sides, and pest control can be ensured.

Moreover, since two irrigating rods are used, it is possible to efficiently control the plants that are planted in many ridges at once.

Moreover, by making the irrigation rod vertical, the rod does not protrude from the left and right sides of the vehicle body, and there is no need to remove the irrigation rod from the vehicle body before or after pest control work, for example, when moving to another field. It is very convenient because there is no such thing.

Therefore, the intended purpose can be achieved.
