Description

Technical Field [0001] The present invention relates to a hose winding device for an agricultural chemical sprayer,

More particularly, the present invention relates to a hose retractor for an agricultural chemical spreader, and more particularly, to a hose retractor for an agricultural chemical spreader, more particularly, So that the hose can be wound while maintaining the wound state, and the hose is wound in a cleaned state when the used hose is wound.

Generally, paddy, field, and orchard are sprayed with pesticide for disaster prevention so that cultivated crops can be protected from pests.

The pesticide sprayed for protection of crops is repeated periodically in accordance with the growth condition of the crop. At this time, one end of the agricultural chemical hose is connected to the power cylinder mounted on the tiller and the operator holds the nozzle stand at the other end of the hose , The pesticide is sprayed on the crops. When the pesticide spraying process is examined, the pesticide is sprayed by using the manual or automatic method.

In the case of manual spraying of pesticides, workers are sprayed on the back and sprayed with pesticides, and the spraying area is applied in narrow and narrow farmland.

In the case of automatic pesticide application, tiller or tractor is applied to apply to paddy fields with a relatively large spray area. At this time, since the hose for spraying the pesticide has a length of more than 100m, the weight of the pesticide needs to be assisted by the auxiliary worker pulling the hose after spraying the pesticide. do.

On the other hand, in the case of spraying the pesticide with the tiller, there is a problem that the pesticide hose wound on the winding drum when spraying the pesticide by the spray pump is loosened by the operator, A separate drive motor is mounted on the wind-up drum to wind up or pull out the agricultural chemical hose.

For example, Patent Literature 10-2013-0006711 discloses a portable lancing device for a pesticide sprayer.

This is because it is possible to spray the pesticide by spraying the hose wound on the take-up roller by forward rotation or reverse rotation of the forward and reverse motors, or by winding the pulley hose around the take-up roller, And reduce work hours and labor costs.

In addition, a pesticide hose winding machine of Utility Model Registration No. 20-0337585 has been proposed.

The present invention relates to an agricultural chemical hose winding machine capable of unwinding or winding a hose for spraying an agricultural chemical by using power, more particularly, And a hose guide which is reciprocated left and right by means of a crank device is provided so that the hog can be wound around the winding roller without any additional personnel.

Also, a utility model registration No. 20-0459118 hose winding machine has been proposed.

This is because when the winding drum rotates rapidly due to strong external pressure, the driving belt rotates the rotating pulley in the clockwise direction to tighten the belt, thereby blocking the rotation of the winding drum to prevent the jetting hose from being quickly released, As a result, the phenomenon of entanglement due to the loosening of the injection hose is prevented beforehand, and the injection hose is loosened smoothly.

However, the above-mentioned conventional technique has a problem that the hose can be wound and loosened stably, and the hose can be operated by a remote controller so that the hose can be stably wound when wound on a take-up reel. There has been a limit in that harmfulness problems arise as the hose slid on the surface is wound around the surface with foreign substances or chemicals.
