Adjustable tree digging-out device

Abstract

The invention discloses an adjustable tree digging-out device. The device includes a power machine arranged on a rack and a gearbox connected to the power machine, wherein the gearbox is connected with a transmission rod connected to a universal coupler, and the universal coupler is connected with a tree digging-out machine through a reversing gear box; an output shaft angle adjusting device is hinged to the tree digging-out machine, and the other end of the output shaft angle adjusting device is connected to the rack. The adjustable tree digging-out device has advantages that the device is wide in working range, light in weight, convenient to carry, small in size, low in cost and convenient to operate, and one person totally can operate the device by himself or herself. The device is suitable for digging of soil balls in any shape, and capable of ensuring integrity of the soil balls, avoiding damage to the root system and substantially increasing the survival rate of plantlets during transplanting. Since the adjustable tree digging-out device is internally provided with the universal coupler and a lifting rod with a spring, when hard objects such as stones are dug during operation of the adjustable tree digging-out device, an effective damping effect can be taken, the comfort level of handling is improved, a hard alloy blade installed on a blade carrier can be effectively protected, and the wear rate of the hard alloy blade is decreased.

Description

technical field [0001] The invention relates to the technical field of tree digging machines, in particular to an adjustable tree digging device. Background technique [0002] At present, tree digging machines with soil transplantation on the market can be divided into large-scale construction machinery tree diggers and small manual tree diggers; large-scale construction machinery tree diggers generally drive multiple arc-shaped cutters through hydraulic cylinders to move trees and soil together from Taken out of the soil, this tree digger has relatively high operating efficiency and can realize automatic excavation, but it is large in size, inconvenient to use and relatively high in cost. Only in large-scale and standardized nurseries can it exert its high-efficiency advantages. At present, most of the nursery production in China is operated by individual households. The planting of the nursery is not standardized, and the intercropping planting density is high. The finishe...
