るようにした農芸用の回転散布器に関する。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a rotary spreader for agricultural and horticultural use that can disperse appropriate liquids such as water, liquid fertilizer, and chemical solutions into extremely fine particles. .

Conventionally, various types of rotary sprayers have been provided in which a rotary body is rotated by the reaction force of the liquid ejected from an ejection hole located away from the center of rotation, and the liquid is sprayed. For example, the water sprinkler like the one shown in Tokko No. 29-383, and the one in Jikko No. 49
There are rotating water spray devices such as No.-385581.

いたからである。 However, these devices were not suitable for making the ejected liquid into extremely fine particles and scattering them high. In other words, liquid leaks from a small gap between the rotary body that rotates due to the reaction force of the liquid ejected from the nozzle and the support body that rotatably supports this rotary body, causing the liquid to flow out of the nozzle. This is because the jetting pressure during jetting may be lowered, it is difficult to expect smooth rotation of the rotating body, and energy loss due to friction of the rotating body is large.

防ぐと共に、回転体が支持具本体に対して少しで
も滑らかに回転するような工夫が必要であつた。 In addition, in the case of spraying equipment using rotary spreaders used for agricultural and horticultural purposes, since many rotary spreaders are installed and used in a spray pipe installed on a large area of land, it is necessary to use a single rotary spreader. The impact on the entire spraying equipment due to a drop in pressure due to liquid leakage or a decrease in the rotational smoothness of the rotating body is significant. An economical problem arises in that additional pressure must be applied to the liquid, which in turn requires a larger and more powerful pressure applying device (such as a compressor). In other words, it was necessary to devise measures to prevent pressure loss due to liquid leakage in one rotary spreader as much as possible, and to allow the rotating body to rotate as smoothly as possible with respect to the main body of the support.

The present invention solves the above-mentioned difficulties and makes it possible to make the ejected liquid into extremely fine particles and scatter them at a high height. In this way, the liquid is released from the gap between the rotating body and the support body. To prevent leakage, prevent drop in jetting pressure when liquid is jetted from the spouting hole, and reduce energy loss of the power device that feeds the liquid into the spray pipe,
Another object is to form the rotating body so that it can rotate smoothly with respect to the support body.

To avoid dust, the cylindrical bearing body D interposed between the shaft portion 5 of the rotating shaft body B and the support main body E has good watertightness and a small coefficient of friction that allows the rotating shaft body B to rotate smoothly. It is now possible to use a sliding bearing material, which improves the smoothness of rotation, helps to increase the rotational speed of the rotating body R, and has the aforementioned effect of atomizing fine spray particles into a high spiral shape. can encourage

たことを特徴とする回転散布器。 In agricultural rotary spreaders, in which the rotary body rotates and spreads liquid by the reaction force of the liquid ejected from a jet hole located away from the center of rotation, the sprayer has a generally elongated hexagonal cylinder shape with a hollow part that serves as a flow path. A nozzle body is formed, a rotating shaft body having a flange extending from the lower end of a cylindrical shaft portion having a hollow portion serving as a flow path, and the hollow portion of the rotating shaft body and the hollow portions of each of the plurality of nozzle bodies. A rotating body is constructed with a branch connection body having a hollow part that communicates with the
A pair of nozzle holes are drilled in which the axes of each hole intersect in an obliquely upward space, and the plurality of nozzle bodies are arranged so that their tips point slightly upward. The male screw part at the upper end of the rotating shaft body is screwed to the lower part of the branch connection body,
A cylindrical bearing body having a flange portion at the lower end and capable of rotatably supporting the shaft portion of the rotating shaft body is formed, and a support body having a male threaded portion on the lower outer peripheral surface into which the cylindrical bearing body can be inserted is formed. A coiled spring and a spring receiver located above the spring are interposed between the lower surface of the branch connection body and the upper surface of the support body, and the elastic force of the spring is applied so that the rotating body is pushed upward. By pressing the appropriate plurality of ring bodies interposed between the lower surface of the flange of the cylindrical bearing body and the upper surface of the flange portion of the rotating shaft body, the lower surface of the support body and the upper surface of the flange portion of the cylindrical bearing body are pressed. A rotary spreader characterized in that it is formed so as to compress an O-ring interposed therebetween.
