Multipurpose double-hydraulic-motor simplified driving system for tree transplanting machine

Abstract

The invention discloses a multipurpose double-hydraulic-motor simplified driving system for a tree transplanting machine. The system comprises lifting lugs, hydraulic cylinders, a left driving system, a right driving system, riding wheel assemblies, jacking wheel assemblies and a hydraulic oil way system, wherein a cylinder body of one hydraulic cylinder is hinged with the middle of one lifting lug, the end part of a piston rod of one hydraulic cylinder is hinged with the upper end of the middle of the left driving system, a cylinder body of the other hydraulic cylinder is hinged to the middle of the other lifting lug, the end of a piston rod of the other hydraulic cylinder is hinged to the upper end of the middle of the right driving system, the multiple riding wheel assemblies are connected with the left driving system and the right driving system, the multiple jacking wheel assemblies are connected with the outer sides of the left driving system and the right driving system, the hydraulic oil way system is connected with the two hydraulic cylinders, the left driving system and the right driving system through oil ways, symmetrical arrangement is adopted, arrangement of a gearbox is avoided, the weight is reduced, and the internal diameter size occupied by a transmission system is reduced; barks are prevented from being broken, and the completeness of the tree after digging is improved; the universality is better, and the centering performance is high; and the transplanting survival rate is high.

Description

technical field [0001] The invention belongs to the technical field of agricultural and forestry machinery. Specifically, the invention relates to a simplified drive system of a multi-purpose dual-hydraulic motor tree moving machine. Background technique [0002] In the process of garden nursery operations and garden engineering construction operations, it is often necessary to transplant live trees. The traditional operation method is to manually draw a circle around the root of the big tree, with the base of the trunk as the center, and extend a certain percentage of radius outwards to draw a circle at a fixed point. The big tree is moved away from the original growth site together with the excavated soil ball. [0003] The research and development of mechanical products for tree-digging operations, especially the research and development of mechanical operation attachments for digging soil balls, is one of the key technologies for developing tree-moving machinery. The p...

Problems solved by technology

[0004] First: The ring gear used is an inner ring gear, so the gear on the output shaft of the gearbox must be arranged inside the ring gear, that is, the drive is realized by an internal meshing method, which not only occupies the internal diameter size, but also the rotating gear is easy to contact with the bark contact, break the skin

The tree mover can only dig soil for trees with a smaller diameter, and the tree mover can only dig soil for trees or shrubs with a larger diameter.

[0005] Second: using a hydraulic motor, the drive train needs to be transformed through the arrangement of the gearbox, which increases the weight of the mechanism and also occupies the internal diameter

[0006] Third: The prior art creates a notch on the complete ring gear, so that the trunk of the tree penetrates the center of the ring gear from the notch. In order to ensure the integrity of the transmission system, the size of the notch on the ring gear is limited, so that Make the tree mover limited in excavating the trees or shrubs with larger diameters

[0007] We have also developed the drive system of the outer ring gear, no matter whether the inner ring gear or the outer ring gear is used, the gear drives the inner ring gear or the outer ring gear to rotate during the working process, and the transmission heat of the contact of the tooth surface makes the lubricating oil or grease heated Gradually melt or the viscosity drops, and then fall off from the tooth surface under the vibration and gravity of mechanical operation, the lubrication is not long-lasting, and the equipment is easy to wear; in addition, the cylindrical gear is directly meshed with the inner or outer ring gear, which affects the performance of the folding hydraulic cylinder. shrink space
