Three-configuration metamorphic type tree pruning and felling machine capable of realizing switching between double two-DOF (two-degree-of-freedom) and SDOF (single-degree-of-freedom)

Abstract

The invention provides a three-configuration metamorphic type tree pruning and felling machine capable of realizing switching between double two-DOF (two-degree-of-freedom) and SDOF (single-degree-of-freedom). The three-configuration metamorphic type tree pruning and felling machine comprises a felling combination mechanism, a walking device, a rack, a driving link, a transmissionlink, triangular supports, an output link, hinge pins, a hydraulic cylinder and a hooke joint. The tree pruning and felling machine can be switched between double two-DOF and SDOF, realizes three different configurations flexibly and has large space characteristics, driving control motors of the machine can be mounted on the rack, so that load of components is reduced, and highly-dynamic stability of movement of the machine is realized; the driving motors are all mounted on the rack, thus, component load caused by the fact that the motors are mounted on rod pieces is reduced, and the dynamic stability is high; the mechanism comprises the full rod pieces, the manufacturing cost is low, the working life is long, and the mechanism is simple to repair and maintain; complicated actions can be realized, and the tree pruning and felling machine can perform tree pruning, trimming, felling and segmented wood cutting operation in forests with harsh environment and rugged terrain.

Description

technical field [0001] The invention relates to the field of tree pruning and felling machines, in particular to a three-configuration metamorphic tree pruning and cutting machine with double-two and single-degree-of-freedom transformations. Background technique [0002] Chinese patent 201610396453.X discloses a logging robot. As described in the document (CN106003071A), the patent realizes the positioning of cutting through the movement of four driving wheels. The working accuracy and flexibility are low, and the movement space is small, so it can only realize logging Task; Chinese patent 201610419380.1 discloses a fully hydraulic automatic logging device for logging machines. This logging device is composed of full hydraulic components. The hydraulic components require high precision, and the hydraulic system has high manufacturing costs. The working life is not long and oil leakage is easy , and can only achieve logging tasks; Chinese patent 201210335835.3 discloses a tre...

The working accuracy and flexibility are low, and the movement space is small, so it can only realize logging Task; Chinese patent 201610419380.1 discloses a fully hydraulic automatic logging device for logging machines. This logging device is composed of full hydraulic components. The hydraulic components require high precision, and the hydraulic system has high manufacturing costs. The working life is not long and oil leakage is easy , and can only achieve logging tasks; Chinese patent 201210335835.3 discloses a tree felling and cutting machine. Can be used in conjunction with construction machinery; Chinese patent 201310427637.4 discloses an electric plant pruning machine, this plant pruning machine is only used for plant pruning, and cannot be used for logging or cutting wood

The existing designs of tree cutting machines all have a single function, small working space, insufficient stability, low precision, and cannot flexibly change the configuration according to functional requirements or changes in the environment to adapt to different tasks and occasions, with low flexibility

[0003] At present, there is no one that can flexibly transform between two two-degree-of-freedom and one single-degree-of-freedom, flexibly realize three different configurations, and has the characteristics of large space, and its drive control motor can be installed on the frame, reducing the The innovative design of tree pruning and felling machine with high dynamic stability and the functions of tree pruning, tree felling and wood interception due to the load of each component
