A co-rotating reciprocating traction device applied to a log picker

Abstract

The invention provides a co-rotating reciprocating traction device applied in a wood pick-up machine. A first steel wire winding and unwinding mechanism is arranged over a drive mechanism. A second steel wire winding and unwinding mechanism is arranged on the right side of a drive mechanism. The first steel wire winding and unwinding mechanism is kept parallel to the second steel wire winding and unwinding mechanism on the inclined lower portion. A tension sprocket is arranged between the first steel wire winding and unwinding mechanism and the second steel wire winding and unwinding mechanism. A universal pulley is fastened on the side face of the front end of a movable arm of the wood pick-up machine through a steel plate. The portion, on the reverse penetrating part of the universal pulley, of a steel wire is sleeved with a material hanging hook. A first transmission wheel and a second slave transmission wheel rotate in the same direction through a transmission chain. An upper steel wire winding drum connected with a first slave transmission wheel and a front steel wire winding drum connected with the second slave transmission wheel also rotate in the same direction. A master transmission wheel, the first slave transmission wheel and the second slave transmission wheel rotate in the same direction through the transmission chain. The co-rotating reciprocating traction device has the beneficial effects of being novel in structure, more stable in operation, more flexible in two-way switching and higher in work efficiency.

Description

technical field [0001] The invention belongs to the field of construction machinery, relates to a forestry wood picking machine, in particular to a co-rotating reciprocating traction device applied to the wood picking machine. Background technique [0002] At present, the timber traction devices used in the log pickers operating in forest farms are all one-way traction structures. This one-way traction device will have the following problems in the actual application process: the one-way traction device will After the wood at the target position is pulled to the wood picker and unloaded, it is necessary to reset the wood pulling device by manpower. This method has the problems of complicated operation and low work efficiency. [0003] The "two-way tractor" described in the invention patent named "two-way tractor" (patent application number: 2016105593445) and the invention patent named "two-way tractor" (patent application number: 2016207484965) A "two-way tractor" is a dev...
