The present invention relates to the technical field of coal loading equipment, and specifically discloses an intelligent coal loading device, including two mobile chassis, a fixed frame and a mounting frame symmetrically arranged front and back. The coal in a clumping state is dispersed by a loading assembly to ensure the fluidity of the coal during the loading process, thereby effectively improving the loading efficiency of the coal. After the coal is dispersed by the loading assembly inside the loading rack, it is diverted inside the movable rack, and then weighed and metered by the metering rack. The movable rack performs reciprocating linear motion inside the bucket of the transport vehicle, so the coal can be evenly loaded into the bucket. Compared with the current method of centralized loading of coal by a loading hopper, the loading method proposed in this scheme can effectively avoid the accumulation of coal inside the bucket. The height of the coal at each position in the bucket after loading is uniform, which effectively reduces the difficulty of subsequent coal leveling operations.

This invention relates to the field of land consolidation and development technology, and in particular to a land leveling device and method with adjustable functions. The leveling method involves first determining a reference horizontal plane, then dividing the farmland into m*n blocks. The bucket passes through n rows of farmland sequentially along a first direction, recording the distances h1 to hn between the reference horizontal plane and the blade. Based on the data h1 to hn, the average distance h between the blade and the reference horizontal plane when in n rows of farmland is obtained. Δh is measured based on the soil volume in the bucket and the farmland area. (h-Δh) is the distance between the target leveling surface and the reference horizontal plane. The bucket height is adjusted to maintain the distance (h-Δh) between the blade and the reference horizontal plane. The process continues along a second direction, passing through m rows of farmland sequentially, completing the farmland leveling. The leveling method provided by this invention facilitates the determination of the target leveling surface and is more conducive to agricultural cultivation and irrigation drainage.
