Description

Traction-type spreaders including a shatterproof nozzle spray unit for adjusting the free angle}

The present invention relates to a sprayer for spraying pesticides or water to various varieties of crops while towing in a narrow furrow of a plastic house or an agricultural field, and more specifically, using an artificial passage between the furrows as they are, The present invention relates to a penetration type spreader having a nozzle spraying unit which can spray and concentrate pesticide or moisture from the outside at a free angle while traction by spraying, thereby naturally concentrating spraying operations without fugitive spraying.

In general, pest control and crop hydration are essential tasks for production and production of agricultural products, and pest control and crop hydration are supplied at a constant pressure to supply pesticides or water in liquid form using external power. Or the worker sprays the crop manually.

In particular, the worker manually holds the nozzle unit spraying pesticide or water by hand and moves it up and down and left and right toward the crop. By moving the nozzle bar one by one, a large area and a long time of control work are performed.

For this reason, various forms of prior art are known for increasing the spread of pesticides or moisture on crops.

For example, in Korean Patent Publication No. 10-2012-0088625 (published date: 2012.08.08.), In a traveling sprayer spraying pesticides using a unicycle trolley, position sensors are placed on both sides of the trolley. And a nozzle-to-binding plate (4) constituting a mounting for coupling the line hole (7) of the sensor to the fixed line hole (5) and the nozzle-to-arm coupling arm (6) and the reducer of the motor. The flange configured in (6) is configured to be compressed at a predetermined pressure by the torque limit 12 coupled to the reducer, and the hinge 19 for coupling the other side of the nozzle-to-arm coupling arm 6 and the nozzle-arm 18 is coupled. And a hinge unit rotating device for a traveling nebulizer, wherein the hinge unit 20 is configured to fix the hinge 19 at a predetermined angle of the hinge 19.

In addition, the Korean Registered Utility Model Publication No. 20-0339604 (published date: 2004.01.12.) Said, "The support (11) which can be provided on both sides by connecting the pipe (11) to the furrow in the house for a long time ( The wagon 2 in which the push rod 22 is fitted to the rail 1 on which the rail 12, which is disposed at a proper interval, and the wheel 21, which is transported on the rail 1, are fitted. And, the mounting plate (42) by welding the flat plate 41 on the top of the push rod 22 of the cart (2) and the device table fixed to the "T" type connector 40 in the binding hole 43 ( 4) and fixing plates 51a capable of accommodating the nozzle 6 on both rods of the rod 22 on both sides, and inserting the nozzle 62 into the accommodating portion 510 on one side, and then bolting them up. The other side is hinged to the support rod 51b and the nut is fixed to the nozzle holder 5 for adjusting the injection angle of the nozzle 6, and the nut to the pipe-shaped push rod sealing ring 52a fitted to the push rod 221. By welding, the bolt is picked up and fixed at an appropriate position of the rod rod 221, and another support rod ring 52b is welded to intersect the rod rod ring 52a to weld the rod 51b of the nozzle holder 51. There is a portable pesticide sprayer for the house, which consists of a nozzle fixing member 5 composed of a control tube 52 which inserts and adjusts its length to fix the bolt.

In addition, Korean Registered Utility Model Publication No. 20-0468718 (published date: 2013.08.23.) Said, "Main passage for supplying liquid at a predetermined pressure;

A first flow path and a second flow path which are fastened to an end of the main flow path, branched to both sides of the main flow path, and bent in a liquid traveling direction of the main flow path;

A first rotary module and a second rotary module provided at ends of the first flow path and the second flow path and having a bearing rotatable therein;

A first injector and a second injector, which are fastened to the first and second rotation modules, respectively, and are branched to both sides with respect to the first and second flow paths, respectively; And spray holes provided at both ends of the first injector and the second injector, respectively, for injecting the liquid supplied to the main flow path.

In addition, the Korean Utility Model Publication No. 20-2017-0000858 (published date: 2017.03.08.) Is known as "A. method of drawing the support to distance the pesticide injection zone away from the human body."

The above-mentioned outboard hand of the domestic patent publication No. 10-2012-0088625 described above comprises a nozzle confrontation plate having a reducer of a motor, a torque limit coupled to the reducer, and a hinge part for fixing the hinge at a predetermined angle. However, a nozzle that is rotated at an arbitrary angle under electric power while being artificially towed by a worker has a complicated structure and a troublesome task to control while the worker moves easily, and also a complicated structure and a troublesome use and safety accident. Problems are inherent,

In addition, the portable pesticide spreader for the house of Korea Registered Utility Model Publication No. 20-2003-0032151 has a problem that a separate rail must be provided inside the house, and the worker has to manually tow when moving, and the spray angle is concentrated when spraying. There is a limit to spray evenly, there is a problem in the installation conditions to apply to the narrow furrow,

In addition, the rotary screw pesticide spreader of the Korean Utility Model Publication No. 20-0468718 is to install a rotary gravel module installed separately in the flow path and then to spray the pesticides to the outside through the injection port of the injection device, but this structure is simply In addition to widespread application range, there is a problem that the efficiency is low due to the large number of unused scattering pesticides, and the cumbersome problem of the installation to connect a separate electrical wiring to the rotating seedlings is inherent,

In addition, the multi-function traveling pesticide sprayer of the Korea Utility Model Publication No. 20-2017-0000585 has a problem that the size of the product increases due to the large number of components of the installation equipment, which runs automatically by its own power, However, if a variable occurs during use, there is a problem that the control caused by the operator and the problem that can be exposed to the safety accidents are inherent, and an improvement plan is required.
