Description

[Detailed description of the invention] "Industrial application field" This invention relates to a portable pesticide spraying device.

``Conventional technology'' Traditionally, pesticide spraying work on fruit trees, vegetable gardens, etc. involved manually transporting a pesticide extrusion pump and its small motor to the field, then connecting the pesticide spraying hose to the pump, and using the hose while dragging the pesticide spraying pump. The pesticide sprayed from a nozzle at the tip was sprayed along the ridges, and after spraying, the hose was manually tied up and discharged from the field by hand, so it was difficult to carry it in and out of the field, and to wind and unwind the hose. It has been difficult to improve work efficiency because the process cannot be carried out smoothly and easily.

``Problem that the invention aims to solve'' This invention aims to improve work efficiency by carrying small-sized motors, pesticide extrusion pumps, pesticide spraying hoses, etc. into and out of fields simply and easily, and unwinding and winding the hoses in an orderly manner. That is.

"Means for Solving Problems" This proposal is to provide a traveling wheel and a brake reel for taking up a pesticide spraying hose at the front of a portable support frame for a small-sized motor and a pesticide extrusion pump, and the support frame below the reel. One end of the reciprocating rod is pivotally supported, and the other end is located at the front lower part of the brake reel, and a hose guide consisting of a horizontal roller and vertical rollers on both sides thereof is provided at the other end, and the guide is connected to the reciprocating rod. The agrochemical spraying device is disposed along with a rod so as to be freely movable in the axial direction at the front lower part of the reel, and a handle is provided on the guide.

``Operation'' Therefore, the rear part of the portable support frame is grasped and lifted, and the support frame is pushed and transported to a predetermined position in the field using the front running wheels, and the rear part is brought into contact with the ground and supported on the ground. Then, one end of the hose wound on the reel is passed through the guide made of horizontal rollers and vertical rollers, and while the hose is pulled along the ridges, the pesticide is sprayed onto the crops from the nozzle at the tip. As the hose is towed, the guide reciprocates in the axial direction along with the hose being unwound from the reel, and since the reel is in a braking state, excessive unwinding due to inertia is controlled. After spraying, place the hose along the ridge, turn the reel with one hand to wind up the hose, grasp the handle provided on the guide with the other hand, and gently move the guide in the axial direction to reciprocate. This allows the hose to be wound up on the reel in an orderly manner.

"Example" A traveling wheel 4 is freely supported at the front part of a portable support frame 3, handles 11, 11 are protruded from the rear part, a bottom plate 12 is provided, and a small motor 1 and a pesticide extrusion pump 2 are mounted on the bottom plate 12.
Equipped with a removable device. A take-up reel 6 of a pesticide spraying hose 5 is freely supported by a horizontal shaft 13 above the front part of the support frame 3, and a coil spring 14 is pressed against the outer peripheral surface of the reel 6 to provide inertial braking. Form the device. In addition, a reciprocating rod 16 freely supported on a vertical shaft 15 is extended to the front of the reel 6 at the lower rear of the reel 6, and at its front end there is a hose guiding guide consisting of a horizontal roller 7 and vertical rollers 8 on both sides thereof. 9 is provided, and a handle 10 is provided at the upper end of the support shafts 8', 8' of the vertical rollers 8, 8. A spray nozzle is provided at the tip of the hose 5, and the base end is connected to the hollow part of the horizontal shaft 13 of the reel 6, and the coaxial shaft 13 is connected to the liquid feeding hose 18 via a rotary coupling 17.
is connected to the discharge port 18 of the pump 2. A pesticide suction hose 20 is connected to the suction port 19 of the pump 2, and a strainer 2 provided at the tip of the hose 20 is connected to the suction port 19 of the pump 2.
1 into the agricultural chemical 23 in the agricultural chemical storage can 22.
In the figure, reference numeral 24 indicates a connecting portion for disassembling and reassembling the support frame 3, 25 indicates a winding drum of the reel 6, and 26 indicates a manual handle of the reel 6.

``Effects'' Since this project is constructed as described above, it is not only possible to very simply and easily transport small motors, agricultural chemical extrusion pumps, agricultural chemical spraying hoses, etc. into the field from the farm road, but also to unwind and rewind the hoses. can be carried out in an orderly manner, improving the efficiency of pesticide spraying work. In particular, one end of a reciprocating rod is pivotally supported on a support frame below the take-up brake reel, and the other end is located at the front lower part of the brake reel, and the other end is provided with a horizontal roller and vertical rollers on both sides thereof. Since a hose guide is provided and the guide is freely movable in the axial direction together with the floating rod at the front lower part of the reel, the mechanism related to the hose winding can be simplified and the entire device can be made smaller. In addition, the hose can be immediately wound onto the brake roller via the hose guide, which is made up of horizontal rollers and vertical rollers on both sides at the front lower part of the reel, eliminating the hassle of hose installation by simply passing the hose through the guide. No work is required, the sliding resistance of the hose can be reduced during winding, the hose can be easily wound with a light force, and there is no fear that the hose will come off the guide during winding.
