A hand-held laser grader

Abstract

The invention relates to a hand-guided laser land leveling machine. A hydraulic cylinder and a supporting rod are arranged on a front frame body, the front frame body is connected with a linkage frame through a connecting base, a tensioning base is arranged at the front end of the linkage frame, and an adjusting base is arranged at the front end of the a rear frame body and is connected with the top of the supporting rod through a telescopic rod; a front swing arm and a rear swing arm are fixed to the front end and the rear end of the rear frame body, and the front swing arm and the tensioning base are each provided with a screw rod and are installed at the two ends of a stabilizing rod; a sleeve is arranged on the upper surface of the rear frame body, a laser receiver is installed in the sleeve through an adjusting nut, a scraper knife is installed at the bottom of the rear frame body, a pressing wheel is connected with the rear swing arm through an installing arm, and a protective plate is installed at the bottom of the rear frame body; a connecting plate is welded to the end of the front frame body, and bolt holes are formed in the surface of the connecting plate. The hand-guided laser land leveling machine is convenient to adjust, flexible in operation, good in leveling effect and wide in application range.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a walk-behind laser grader. Background technique [0002] The use of laser levelers in farmland farming is very common today. The practical effect of laser leveling systems on transforming saline-alkali land into cultivated land has been practiced in Inner Mongolia, Ningxia and other regions. Today's laser graders only control the height of the shovel to improve the accuracy of land leveling in the field. However, when leveling the land with a large height difference, it is necessary to adjust the shovel according to the different ground heights during the operation. After the leveling shovel has been adjusted many times, the horizontal position of the leveling shovel is very easy to change, causing the leveled land to meet the flatness requirements but not in the horizontal position, resulting in the whole land relative to the horizontal position There is an inclination an...

Today's laser graders only control the height of the shovel to improve the accuracy of land leveling in the field. However, when leveling the land with a large height difference, it is necessary to adjust the shovel according to the different ground heights during the operation. After the leveling shovel has been adjusted many times, the horizontal position of the leveling shovel is very easy to change, causing the leveled land to meet the flatness requirements but not in the horizontal position, resulting in the whole land relative to the horizontal position There is an inclination angle, and the land level after different leveling processes is very different, resulting in poor leveling effect and reduced accuracy
