<p>Disclosed is a rotavator-integrated-type laser balancer formed to integrate a rotavator, which harrows the surface of a field, and a scraper, which levels the harrowed surface of the field, by a joining member. The scraper is lifted up independently by a hydraulic cylinder, supported by the joining member. Hydraulic pressure of the hydraulic cylinder is controlled by a leveling control means, which calculates an average high and low value of the surface of the field and transmits a control signal based on the average high and low value. The joining member comprises: a joining frame which is fixated and installed in a horizontal state on a rear side of the rotavator; a horizontal bar which is fixated and installed on an end portion of the joining frame to be perpendicular to the joining frame and supports the hydraulic cylinder; a guide pipe which is vertically installed on the joining frame by a bracket as a joining means; and a vertical guider which is slid in the guide pipe when the scraper is lifted up while one end portion of the vertical guider is fixated on the scraper and the other end portion of the vertical guider is inserted in the guide pipe.</p> |
