Labor reduction type agricultural chemical spraying system having automatic hose winding and unwinding apparatus

Abstract

The present invention relates to a labor reduction type agricultural chemical spraying system having an automatic hose winding and unwinding apparatus by which one worker is capable of spraying agricultural chemicals in such a manner that a hose is automatically wound and unwound from a reel based on a remotely controlled motor. The labor reduction type agricultural chemical spraying system having an automatic hose winding and unwinding apparatus comprises a frame in which a motored sprayer connected with an engine is installed; a reel rotatably installed in the frame wherein a hose is wound onto the reel; a first driving motor driven in both directions for rotating the reel in normal and reverse directions in accordance with a remote control signal; a rotary shaft rotating by a driving force from the rotary shaft of the reel and reciprocating a movable piece engaged to an upper side in the left and right directions with respect to the reel; a second driving motor installed on the movable piece in cooperation with the first driving motor and driven in the normal and reverse directions in accordance with a remote control signal; and a pair of rollers that are installed in the movable piece and are rotatably connected with the second driving motor and tension an outer surface of the hose, and unwind the hose from the reel.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a labor reduction type agricultural chemical spraying system having an automatic hose winding and unwinding apparatus by which one worker is capable of spraying agricultural chemicals in such a manner that a hose is automatically wound and unwound from a reel based on a remotely controlled motor, and in particular to a labor reduction type agricultural chemical spraying system capable of enhancing a productivity in such a manner that a certain agricultural chemical is sprayed to farm products using a hose automatically unwound from a reel, and the hose is automatically unwound onto the reel based on a remotely controlled motor after work for thereby achieving a mechanical system and an automation in a farming work. [0003] 2. Description of the Background Art [0004] Generally, in the case that an agricultural chemical is sprayed with respect to the farm products in a vinyl house, a ri...

Benefits of technology

[0012] Accordingly, it is an object of the present invention to provide a labor reduction type agricultural chemical spraying system having an automatic hose winding and unwinding apparatus capable of significantly decreasing a worker's labor and a cost of workers in such a manner that a hose is automatically wound onto a reel in accordance with a remote control signal in a remote area, and only one worker is capable of spraying farm products with agricultural chemicals.

[0013] It is another object of the present invention to provide a labor reduction type agricultural chemical spraying system having an automatic hose winding and unwinding apparatus capable of achieving a desired work competitive power based on a reduced labor in such a manner that the length of a hose is automatically controlled by an assistant pulling apparatus at an intermediate position of a way of a farm field when an agricultural chemical is sprayed using a long hose, so that one worker can do an agricultural chemical spraying work.

[0014] It is further another object of the present invention to provide a labor reduction type agricultural chemical spraying system having an automatic hose winding and unwinding apparatus capable of enhancing a workability in such a manner that a twisting of a hose wound onto a reel after work is prevented, and the hose is uniformly wound onto the left and right sides of the reel, and the hose is fast wound onto the reel.

Problems solved by technology

The hose has a length of over 100 m. Therefore, an assistant is necessarily needed for manually winding or unwinding the hose after the work because the hose has a heavy weight.

Since two or three workers are needed for a spraying work of agricultural chemicals, the cost of workers is increased wherein the workers lack in the farm areas, the workers are aged, and the women occupy major part in the workers.

Therefore, the cost of the workers is increased, and the competitive power is decreased.

Since the winding work of hose having a certain weight and a slippery skin is repeatedly performed, the workability is decreased.

A communication is bad between workers due to an engine noise, etc.

However, when the hose 2 is wound onto the reel 3 based on the driving operation of the driving motor 4 after work, the hose 2 is not uniformly wound onto the left and right sides of the reel 3.
