Adaptive disc type stumping device

Abstract

The invention discloses an adaptive disc type stumping device. The device is in a telescopic arm structure which is telescoped by a telescopic oil cylinder; a telescopic arm and a cutting knife part are driven to move from side to side by the side-to-side movement of the oil cylinder; the ground clearance of a cutting knife disc is adjusted by lifting the oil cylinder; the telescopic arm can swing in an angle range of 150 degrees by a worm and worm wheel mechanism; the telescopic arm can be lifted and descended by the pitching movement of the oil cylinder; the cutting knife disc is driven by a hydraulic motor (in an electric motor or other mechanical transmission form) to rotate at high speed, and knife blades fixed on the cutting knife disc do centrifugal movement to cut off shrubs; the cutting knife disc and the telescopic arm are hinged so as to adapt to the change of the pitch angle of the telescopic arm and keep the cutting knife disc horizontal; and the knife blades are in an active avoiding structure, so that when a hard object is encountered and can not be cut off, the knife blades are passively retracted to prevent the cutting knife part of the stumping device from being damaged. The adaptive disc type stumping device is used for cutting shrubs and stumping on a sandy ground, has strong adaptability to the shrubs grown on a complex sandy ground, and can meet the requirement of long-time operation in a large area.

Description

technical field [0001] The invention relates to a device for harvesting stubble in sandy bushes, in particular to an adaptive disc-type stubble device. Background technique [0002] In recent years, sand-growing shrubs have been planted in large areas in desert areas in order to prevent wind and fix sand, maintain soil and water and ecological balance. Shrub forests not only have ecological benefits, but also can be used as industrial raw materials for pulp and paper making, feed production, and biomass power generation. According to the biological characteristics of sand shrubs, stubble must be stubbled every 3 to 5 years. After stubble, the growth is accelerated, the germination power is strengthened, and it has a rejuvenation effect. [0003] The small back-mounted or side-mounted brush cutters commonly used in the prior art cannot meet the requirements of long-term and large-area operations, and the labor intensity is high, and the vibration during the irrigation proces...
