The present invention provides a device for absorbing a shock and adjusting an angle of an auxiliary harrow (20) installed on one side of a support (30) installed to be able to be rotated by being mounted on a rotary shaft (11) formed on both sides of a central harrow (10). The device of the present invention includes: a body (110) which is installed at one side top of the auxiliary harrow (20); a rotary shaft (112) which penetrates through both the body (110) and the support (30) in order to be coupled; a support body (120) which is formed at the outside of the support (30); a rotated body (130) which is installed at the top of the other side of the auxiliary harrow (20); a support shaft (140) which is formed at the top of the rotated body (130) and is coupled with the support body (120); and an elastic member (150) which is installed between the rotated body (130) and the support body (120) when inserted in the outer circumference of the support shaft (140). In the present invention, when the auxiliary harrow is moved to pass through or collide with an obstacle, buffering functions are naturally performed in an up and down direction, and damage can be preemptively prevented. Moreover, a worker can easily adjust an up and down angle of the auxiliary harrow so that paddy field flatness efficiency can be maximized. The device of the present invention especially has a simple structure and can be easily installed, so that the scope of utility and efficiency in use can be improved. |
