The invention provides a folding type laser land leveler, and relates to the technical field of laser land levelers. Two first guide rods of a cylindrical rod-shaped structure are welded to the top end face of the traction base, a connecting arm is arranged on the two first guide rods in a sliding mode, two first electric cylinders are fixed to the top end face of the traction base, and the extending ends of the two first electric cylinders are fixed to the connecting arm. On one hand, after the auxiliary hoppers are unfolded, a third electric cylinder is controlled to stretch, the third electric cylinder pushes a first locking arm to move downwards, and after the first locking arm is connected with a scraping hopper body and locking blocks on the auxiliary hoppers in a clamped mode, locking of the two auxiliary hoppers can be achieved; and on the other hand, when the first locking arm moves downwards to achieve locking, the two second locking arms are extruded through the extrusion blocks, the auxiliary bucket is locked again through the second locking arms, compared with an existing device, the device can achieve double locking synchronously, the locking effect is good, and the stress strength of the unfolded auxiliary bucket is improved.
本发明提供一种折叠式激光平地机，涉及激光平地机技术领域，包括：牵引座；牵引座顶端面焊接有两根圆柱形杆状结构第一导向杆，两根第一导向杆上滑动有连接臂，牵引座顶端面固定有两根第一电动缸，两根第一电动缸的伸出端均固定在连接臂上。一方面，在将辅助斗展开后，控制第三电动缸伸展，第三电动缸推动第一闭锁臂向下移动，当第一闭锁臂与刮斗主体以及辅助斗上的闭锁块卡接后，可实现两个辅助斗的闭锁；另一方面，在第一闭锁臂向下移动实现闭锁的同时，通过挤压块对两个第二闭锁臂的挤压，实现了第二闭锁臂对辅助斗的再次闭锁，与现有装置相对比，本装置能够同步实现双重闭锁，闭锁效果好，提高了辅助斗展开后的受力强度。
