Arranged in the direction.

  Next, the usage method, action, and effect of this tea garden chemical spreader will be described.

  First, when the medicine is sprayed on the tea ridge 50, as shown in FIGS. 1 and 2, the two sets of the chemical liquid conduit 14 and the air blowing duct 24 are substantially brought into contact with both side surfaces of the tea ridge 50, respectively. . At this time, the plurality of chemical solution discharge ports 16 and the plurality of blower outlets 25 face the side surface of the tea ridge 50 (the skirt portion of the tea tree 51).

  Thereafter, an operation cock (not shown) is opened, and the chemical liquid in the chemical liquid tank 11 flows into the two chemical liquid conduits 14 and 14 via the power sprayer 12, and as shown by the white arrow A, The medicine is ejected in a mist form from the chemical solution discharge port 16 of the nozzle 15. At the same time, the blower operating lever 43 provided in the operation unit 4 is operated to move the blower 21 so that the wind of the blower 21 flows into the two blower ducts 24 and 24 through the intermediate duct 22. Then, as shown by a black arrow B, the air is blown out from the blower outlet 25. Note that the medicine may be ejected in a linear shape, a dotted shape, or the like from the chemical solution discharge port 16 of the nozzle 15.

  At this time, since the plurality of air outlets 25 of the air duct 24 and the plurality of chemical liquid outlets 16 of the chemical liquid conduit 14 are opened in the vicinity, the chemical liquid ejected from the chemical liquid outlet 16 is The strong wind (pressure wind) forcibly sent out from the blower outlet 25 blows vigorously on both sides of the tea tree 51 and enters the inside of the tea tree 51, and the whole tea tree (branch trunk, leaf table and It spreads out behind the leaves).

  Therefore, the degree of adhesion of the chemical liquid to the tea tree 51 is improved and the unevenness of spraying is reduced, and the control effect is improved. In addition, the amount of sprayed chemical solution can be reduced, which is economical, and the work time can be shortened to improve the work efficiency. Further, since the structure is simple, for example, the existing tea garden medicine spreader can be effectively used by attaching and using the blower 21 and the air duct 24 to the existing tea garden medicine spreader.

  Specifically, the optimal period for control of stag beetles is about one week from the day of hatching, and it is necessary to spray chemicals within that short period. desired. Therefore, by using the tea garden chemical spraying device of the present invention, the chemical solution enters the tea tree 51 and spreads throughout the tea tree, so that the degree of adhesion of the chemical solution to the tea tree 51 is improved, and uneven dispersion is reduced. The For this reason, the control effect of the stag beetle which inhabits the branch trunk part of the tea tree 51 improves. In addition, it becomes possible to increase the traveling speed of the tea garden chemical spraying machine, the work efficiency is improved, and the spraying amount of the chemical liquid is reduced as compared with the conventional one, which is economical.

  In addition, each of the plurality of blower outlets 25 and each of the plurality of chemical solution outlets 16 are arranged in a direction substantially perpendicular to the longitudinal direction, and each of the plurality of blower outlets 25 is Since there is a one-to-one correspondence with each of the plurality of chemical solution discharge ports 16, the chemical solution can be reliably sent to the whole tea tree 51 without waste.

  Moreover, since the said air duct 24 and the said chemical | medical solution conduit | pipe 14 are located in the back of each of the right-and-left leg parts 1a and 1a of the said main body frame 1, a chemical | drug | medicine is on the opposite side to the running direction of the said chemical spraying machine for tea gardens. It is possible to prevent the medicine from being applied to the operator.

  Since the air duct 24 and the chemical liquid conduit 14 are inclined forward, the tea garden medicine spreader when moving (turning) from the tea ridge 50 that has finished spraying to the next tea ridge 50. Even if the main body does not surely exceed the tea ridge 50, it can turn smoothly without contacting the tea tree 51, and the work efficiency is improved. That is, when the blower duct 24 and the chemical solution conduit 14 are fixed perpendicularly to the ground, when the tea spray 50 is moved from the tea ridge 50 to the other tea ridge 50, the tea garden drug spreader is used. If the main body does not reliably turn over the tea ridge 50, there is a drawback of contacting the tea tree 51.

  Further, since the chemical solution is sprayed by blowing air in the tea garden, it is less scattered by natural wind compared to spraying on the surface of the tea garden, and exposure to other adjacent tea gardens, human beings and animals and plants is avoided.

  Further, since the Y-shaped tube 22b is located at the approximate center in the left-right width direction of the main body frame 1, it is possible to distribute the air from the blower 21 to the left and right blower ducts 24, 24 substantially evenly, and It is possible to blow out air of substantially the same air volume and pressure from the air ducts 24, 24. In this way, with a simple configuration, the spraying state of the medicine from the left and right of the tea garden medicine spraying machine can be made substantially the same. Further, since the Y-shaped tube 22b is located between the blower 21 and the left and right blower ducts 24, 24, the flow path of the wind from the blower 21 can be reduced, thereby reducing the number of parts and reducing the size. be able to.
