<p>PURPOSE:To improve connection strength by providing a hose with a small diameter end being jetting side, a joint main body of hose fitting part connecting the hose, an outer cylinder fixed to the joint main body, a pair of force-fitted cylinder, and a joint composed of a plurality of small iron balls. CONSTITUTION:Hoses H1, H2 with different diameters are connected. There are provided hoses with different diameters with an end of the hose H2 being the discharge side of agricultural agent liquid, a joint main body A with both sides of a flange part 1 being hose fitting-in parts 2a, 2b, an outer cylinder B provided with female screw 6b at the inner face of cylinder having an inner diameter corresponding to the outer diameter of the flange part 1 of the joint main body A, a pair of force-fit cylinders D1, D2 whose minimum diameter of inner surface is in correspondence to the outer diameter of hose, and each small iron ball E sealed in between the cylinders D1, D2 and the hose outer circumference. As a result, the pulling force is alleviated with atomizing amount and pressure being kept.</p> |
