Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a spray type sprayer including a free angle adjustable spray-

The present invention relates to a spreader for spraying pesticides or water on crops of various kinds while towing in a narrow groove of a vinyl house or an agricultural field. More particularly, the present invention relates to a spreader which uses human pathways between furrows, Type sprayer having a nozzle spraying unit capable of spraying the spraying work by concentrating the spraying operation naturally without fogging by adjusting the pesticide or water supplied from the outside at a free angle while towing the spraying unit.

Generally, in order to produce and produce agricultural products, pest control and crop water supply are essential. In order to control pests and to supply crop water, the pesticides or moisture in liquid form are supplied by constant pressure Or the operator manually applies the spray to the crop.

In particular, the operator manually moves the nozzle stand to spray the pesticide or water and moves it up and down and side to side to the crops one by one to perform the cleaning work. Such manual cleaning work is carried out so that the worker can spray the agricultural chemicals or water evenly The nozzles are moved one by one to carry out the cleaning operation over a large area and for a long time.

For this reason, various forms of prior art are known to increase the spread of pesticides or water evenly on crops.

For example, in Korean Patent Laid-Open Publication No. 10-2012-0088625 (published on Aug. 8, 2012), "in a traveling sprayer for spraying pesticides using an unicycle, a position sensor And a nozzle confronting plate 4 constituting an attaching portion for engaging the line hole 7 of the sensor body constituted in the nozzle to engaging arm 6 with the speed reducer of the motor, The flange constructed in the crankcase 6 is configured to be pressed by the torque limit 12 coupled to the reduction gear at a predetermined pressure and the hinge 19 for coupling the other side of the nozzle to coupling arm 6 with the nozzle arm shaft 18 , And a hinge holding part (20) for fixing the hinge (19) at a predetermined angle of the hinge (19) is constituted.

In addition, in the domestic registered utility model No. 20-0339604 (public date: January 12, 2004), "a pipe 11 is provided on both sides of a house in a house, A carriage 2 in which a plunger 22 is fitted to a pallet 20 on which a rail 1 on which a pallet 12 is arranged in a suitable manner and a wheel 21 on which the pallet can be transported on the rail 1, And a flat plate 41 is welded to an upper end of the bar 22 of the wagon 2 to provide a mounting table 42. The flat plate is provided with a mounting table 43 having a "T" And a fixing plate 51a on both sides of which the nozzle 6 can be received is provided on both sides of the rod 22 so that the nozzle 62 is inserted into the receiving part 510 at one side and then the bolt is picked up And the other end thereof is hinged to the support rod 51b to adjust the spraying angle of the nozzle 6 and a nozzle fixing base 5 for adjusting the spray angle of the nozzle 6, The welding rod 51b of the nozzle fixing table 51 is welded to another fixing rod ring 52b so as to intersect with the fixing rod ring 52a , And a nozzle fixing member (5) composed of an adjusting pipe (52) for inserting and fixing a bolt by adjusting the length thereof. &Quot;

In addition, in Korean Utility Model Application No. 20-0468718 (published on Aug. 23, 2013), "a main flow path for supplying liquid at a preset pressure;

A first flow path and a second flow path which are coupled to an end of the main flow path and branch to both sides of the main flow path and are curved in a liquid traveling direction of the main flow path;

A first rotation module and a second rotation module which are provided at the ends of the first and second flow paths and in which a rotatable bearing is formed;

Also, domestic public utility model No. 20-2017-0000858 (publication date: March 20, 2017) discloses a method of pulling out a support rod to distant a pesticide nozzle from the human body.

In the aforementioned unoccupied handrail of the above-mentioned Korean Patent Laid-Open Publication No. 10-2012-0088625, a nozzle confluent plate having a reducer of a motor, a torque limit engaged with the reducer, and a hinge supporter for fixing the hinge at a predetermined angle are constituted However, there is a problem that the nozzle, which is powered by electric power and rotated at an arbitrary angle, is complicated in structure and requires a lot of work to be carried out while the worker moves it easily, and also has a complicated structure, And the problem is inherent,

In addition, the domestic registered utility model No. 20-2003-0032151 has a problem that a separate rail must be provided inside the house, and that a worker has to artificially tow it, There is a limit to uniform spraying, and there is a problem in the installation conditions for application to a narrow furrow,

In addition, the rotating screw pesticide sprayer of the Korean Registered Utility Model No. 20-0468718 has a rotary module installed separately in the flow path, and then pesticides are sprayed to the outside through the injection port of the spraying device. However, In addition, there is a problem that the efficiency of the pesticide is low due to a large number of unused pesticide pesticides. In addition,

In addition, the multifunctional pesticide spreader of the domestic registered utility model 20-2017-0000585 has a problem that the size of the product is increased due to a large number of components of the installation equipment of the self- However, when a variable is generated during use, there is a problem that it must be controlled through a worker and exposed to a safety accident. Therefore, there is a need for an improvement thereof.
