[Structure] Agricultural chemical spraying pipes with two sponge coating sponges attached in parallel to the front and back are laid horizontally, and agricultural chemicals are supplied to each agricultural chemical spraying pipe through a hose, and one agricultural chemical spraying sponge is rotated forward. The other pesticide application sponge is configured to rotate in the reverse direction.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a configuration of a pest control device that travels while performing a pest control operation on grasslands such as lawns.

[0002]

[Prior Art]

 Conventionally, as a lawn control device, as shown in FIG. 6, a spray rod 20 is horizontally arranged in the width direction of the machine body, and pesticides are sprayed from the nozzles 21, 21 ... Of the spray rod 20. While it was moving and spraying.

[0003]

[Problems to be solved by the device]

 However, conventional pesticide spraying systems spray a large amount of pesticide because the pesticide is attached mainly to the front side of the leaves and to the back side only a small amount of pesticide that has spilled around in a mist form. It was. Therefore, it was wasteful, became an environmental problem, and led to high costs. Therefore, the present invention intends to solve the above problems by providing a pest control work machine that effectively applies pesticide to grass leaves and requires a small amount of pesticide.

[0004]

[Means for solving the problem]

 The problems to be solved by the present invention are as described above. Next, in order to solve the problems, in a control device for lawn grass and the like, a pesticide spray tube having two sponges for applying pesticide applied in parallel in front and back is used. It is constructed so that the pesticides are supplied horizontally to each pesticide ejection pipe via a hose, one sponge for applying pesticide is rotated in the forward direction, and the other sponge for applying the pesticide is rotated in the reverse direction.

[0005]

[Action]

 The problems to be solved and the means for solving the problems of the present invention are as described above. Next, the operation will be described. That is, the pesticide in the medicine tank 1 mounted on the pesticide application device is pumped by the pump 2 to the pesticide spray pipe 3 in the pesticide application device T, penetrates into the pesticide application sponge 4 through the ejection holes 3a, and the pesticide application is performed. The medicine is administered by rotating the sponge 4 for spraying on lawn or the like. Further, two pesticide application sponges 4 are attached to one pesticide application device T, and one pesticide application sponge 4 rotates along the traveling direction and the other pesticide application sponge 4 rotates in the reverse direction. The pesticide can be applied to the back side of the grass leaves.

【Example】

 Next, a configuration of an embodiment according to the present invention will be described with reference to the accompanying drawings. Fig. 1 is a plan view of the pesticide application device of the present invention mounted on a tractor, Fig. 2 is a perspective view of the pesticide application device T, Fig. 3 is the same plan sectional view, Fig. 4 is the same side view, and Fig. 5 is for pesticide application. It is a side sectional view of a sponge.

In FIG. 1, the pesticide applicator T of the present invention is arranged in front of and on both sides of the front of the tractor A so that a wide range of pesticides can be applied. It is constructed so that it can be raised and lowered and stored. A chemical tank 1 is placed on the rear part of the tractor A, a pump 2 driven by the engine is mounted near the engine in the front part of the tractor A, and the pesticide is applied to the pump 2 via the hose 15 from the chemical tank 1. Is supplied and the pesticide is sent from the pump 2 to the pesticide application device T via the hoses 16, 16, 16.

As shown in FIGS. 2 to 5, the pesticide application device T is entirely covered with a pesticide application part cover 5, and a support part is provided on the pesticide application part cover 5 to form a hydraulic cylinder 6. Auxiliary wheels for connecting and elevating the pesticide application device so that the pesticide application device can be adjusted to an appropriate height, and for facilitating movement of the pesticide application device T on both front and rear sides of the pesticide application cover 7. 7/7/7 is installed.

Two pesticide ejection pipe mounting portions 5a are vertically provided on both side surfaces of the pesticide application portion cover 5, and two pesticide ejection pipes are arranged in front and back in parallel between the pesticide ejection pipe mounting portions 5a on both left and right sides. 3F and 3R are horizontally installed, and a pesticide supply hose 16 is connected from the pump 2 to one end of both pesticide ejection pipes 3. Around the pesticide ejection pipe 3, a large number of ejection holes 3a and 3a. . Is opened, and a pesticide application sponge 4 is attached to the outer peripheral surface of the pesticide ejection pipe 3.

The pesticide spraying pipe 3F on the front side of the pesticide spraying pipe 3 has a gauge ring 8 fixed between the pesticide spraying sponge 4 and the pesticide spraying pipe mounting portion 5a. As the pesticide application device T moves, it rotates in contact with the lawn to maintain the pesticide application device T at a constant height, and the pesticide application sponge 4 is compressed with a constant pressure so that the pesticide can seep out a certain amount. . As shown in FIGS. 3 and 4, sprockets 9F and 9R are fixed to one side of the pesticide spray pipes 3F and 3R, and two sprockets 11F and 11F. 11R and gears 12F and 12R are fixedly installed. A chain 10F is wound between the sprockets 9F and 11F, a chain 10R is wound between the sprockets 9R and 11R, and the gears 12F and 12R are meshed with the front pesticide ejection pipe 3F. The agricultural chemical application sponge 4F rotates in the forward direction along the traveling direction, and the agricultural chemical spray tube 3R on the rear side and the agricultural chemical application sponge 4R are rotated in the reverse direction via the sprocket, chain and gear.

With the above configuration, the pump 2 sucks pesticide from the medicine tank 1, pressure-feeds the pesticide to the pesticide spraying pipe 3 of the pesticide spraying device T through the hose, and from the spraying hole 3 a of the pesticide spraying pipe 3. After the pesticide penetrates into the pesticide application sponge 4 and the pesticide application device advances, the front pesticide application sponge 4 rotates forward in the direction of the arrow in Fig. 4 to apply the pesticide, and then the pesticide on the rear part. The sponge 4 for application moves forward while rotating in the reverse direction to apply the pesticide on the opposite side of the grass leaf. If this pesticide application device T is attached to the back of the mower, it is possible to spray pesticides at the same time as lawn mowing.

[0012]

[Effect of the device]

 The present invention has the following effects by being configured as described above. In other words, one sponge that has penetrated two pesticides rotates in the normal direction and the other rotates in the reverse direction. Therefore, it becomes possible to apply the pesticide effectively over the front and back surfaces of grass leaves such as lawns. The amount of spraying does not fluctuate over time, and wasteful chemicals such as the conventional spraying control work can be suppressed, reducing the need for pesticides and reducing costs. Since it does not scatter, the operator's work is reduced and the control work can be performed without being affected by the wind.
