摘要

The drip hose and the mulching vinyl replacement machine according to the present invention may include a vertical plate 110 provided at both sides, a support bar 120 coupled to upper and lower ends of the vertical plates 110 to fix the vertical plate 110, A main body 100 composed of an axial groove 111 extending from the upper end of the vertical plate 110 to the center and an operation drum 130 rotatably installed in the axial groove 111; A driving unit 200 installed at one side of the vertical plate 110 at one side of the main body 100 and transmitting the driving force of the motor 210 to the driving shaft 330 through the speed reducer 220; A disc main plate 310 attached to the outer surface of the speed reducer 220 provided with the driving shaft 330 by the magnetic force of a magnet 311 embedded at equal intervals along a concentric circle and an operating plate bolted to the disc main plate 310 A drive shaft 330 installed in the reducer 220 through the disk plate 310 and the operation plate 320 at the same time and a driven shaft 340 axially installed inside the drive shaft 330 so as to idle, A clutch device unit 300 configured by: A plurality of ball guide tubes 412 are protruded and formed in a vertical direction along a concentric circle at the periphery where a through hole 411 is formed at one side, And a frictional disk 430 attached to the engaging groove 413 of the operating disk 410. The friction disk 440 is attached to the engaging groove 413 of the operating disk 410 A configured tension adjuster 400; And,A control unit 140 is disposed on an outer surface of the vertical plate 110 at one side of the main body 100. A driven bolt 132 is coupled to one side of the operation drum 130 of the main body 100, Strings 131 are formed on the outer circumferential surface of the operation drum 130 so as to be fitted in the axial grooves 111 of the vertical plate 110 and both ends of the operation drum 130 are moved along the axial grooves 111 of the vertical plate 110 A motor 210 is installed below the speed reducer 220 of the driving unit 200 and a driving shaft 330 is installed above the speed reducer 220, The operating surface (inner circumferential surface) 321 of the operating plate 320 of the unit 300 is constituted by a narrow portion 321a having a small diameter and an enlarged portion 321b having a gradually increasing diameter, And a pin groove 331 and a pin insertion hole 332 are formed on the outer peripheral surface of the driving shaft 330 of the clutch device unit 300. The outer peripheral surface of the driven shaft 340 And a pin receiving groove 341 having a detaching surface 341a formed in the opposite direction and inserted into the pin insertion hole 332 of the drive shaft 330 to be engaged with the pin seat 341a of the driven shaft 340 A magnet 343a is mounted on the pin 343 of the clutch device unit 300 and the coupling shaft 343a of the tension adjusting unit 400 is connected to the driving shaft 330. [ An annular engaging groove 431 is formed on the outer circumferential surface of the friction disc 430 of the tension adjusting unit 400 and a driving bolt 432 is formed on the outer surface of the frictional disc 430. [ And a female thread hole 412d and a guide hole 412e are formed in order at the center of the ball guide tube 412 of the working disk 410 of the tension adjusting unit 400 to communicate with the inner surface of the friction disk 430 And the friction ball 412c and the spring 412b are successively inserted into the guide hole and the crimp bolt 412a is screwed into the female screw hole 412d so as to adjust the strength of the friction ball 412c pressing the inner surface of the friction disk 430 A female screw hole 414c and a guide hole 414d are formed in order at a central portion of the guide tube 414 of the working disk 410 of the tension adjusting portion 400 to form a friction The connecting rod 414b is fitted into the guide hole 414d and is in contact with the annular fitting groove 431 of the friction plate 430 and the pressing strength of the connecting rod 414b is adjusted And the driving bolt 432 of the frictional plate 430 is engaged with the driven bolt 132 of the operation drum 130. The driving bolt 432 of the friction plate 430 is engaged with the driving bolt 414a of the driving drum 130, And includes that the working drum (130) rotate together when the working disk (410) rotates.
