Tree excavating machine outer meshing rotating driving device

Abstract

The invention discloses a tree excavating machine outer meshing rotating driving device. The tree excavating machine outer meshing rotating driving device comprises an upper bearing ring, a lower bearing ring, a driving motor, a worm and gear reducing mechanism and a transfer case. The lower bearing ring is rotationally installed at the bottom of the upper bearing ring. One side of the upper bearing ring and one side of the lower bearing ring are provided with openings with the same angle. The two ends of the transfer case are each rotationally provided with a transmission shaft. The lower ends of the transmission shafts are provided with gears respectively. The lower bearing ring is provided with an outer gear ring. The gears are meshed with the outer gear ring and located at the two sides of the opening in one side of the lower bearing ring. By means of the tree excavating machine outer meshing rotating driving device, it is guaranteed that an excavated soil ball is very round, a large tree root can be sawed off, stone and other barriers can be conveyed out through a chain, and the tree excavating machine outer meshing rotating driving device will not get stuck easily; it is guaranteed that a tree excavating machine can be provided with an angle adjusting device, the tree excavating machine can conduct excavating on the ground with certain slope, the excavated soil ball can meet the requirement for tree transplanting, and the problems of excavating and transplanting of seedlings on the conditions of hills, mountain slopes and the like are solved.

Description

technical field [0001] The invention relates to the field of tree digging machines, in particular to an external meshing rotary driving device of the tree digging machine. Background technique [0002] With the acceleration of the process of agricultural mechanization, various types of agricultural machinery have entered into production practice one after another. At present, in addition to the production and processing of field crops and some economic crops, in addition to the use of operating machinery, most forestry nursery operations need light, high-efficiency tree-digging machinery to replace the increasingly scarce rural labor resources and improve operating efficiency. quality and efficiency. my country has a vast territory, not only in topography, landform, geological soil structure, but also in the characteristics of plants in various places. Especially in forestry nurseries, landscaping and other environments, there is an urgent need to develop small and medi...

AI Technical Summary

Problems solved by technology

[0003] Existing tree diggers include portable chainsaw type, side screw-in type and down-insert type, etc. The portable chainsaw type still requires manual and laborious operation, and the soil balls dug out without experience are not round and the efficiency is not high; The size of the side screw-in and down-insert soil balls cannot be adjusted. When digging a tree on a certain slope without an angle adjustment device, the tree dug out will be eccentric, and it will not be able to dig when encountering stones and large roots.
