Problems solved by technology

[0002] With the improvement of forestry logging safety requirements and the improvement of efficiency, more and more mechanical automation equipment is used in forestry logging occasions to improve logging efficiency and logging quality while reducing labor and ensuring logging safety. The diameters of different positions are different. When the wood is cut and measured according to the specified length, the existing mechanical automation equipment cannot measure and adjust according to the different positions of the wood, resulting in poor accuracy of the actual cut length of the wood.

Abstract

The invention discloses a wood fixed-length measurement cut-off control device and method for a felling machine in the technical field of hydraulic control of felling machinery, and the device comprises a driving part which outputs a driving signal; the feeding part drives wood to be fed based on the driving signal; the length sensor is used for measuring the feeding length based on the wood feeding process; the device further comprises a length measuring oil cylinder and an energy receiving device, a piston rod of the length measuring oil cylinder is connected with a length sensor, and the length sensor abuts against the wood by adjusting the oil pressure of a cavity of the length measuring oil cylinder through the energy receiving device. The length measuring oil cylinder is dynamically compensated through the energy accumulator, when the diameter of wood changes, the length sensor is kept in abutting contact with the wood, and real-time measurement and accurate control over the length are achieved.

Description

technical field [0001] The invention relates to a device and a method for controlling the fixed-length measurement and truncation of timber of a logging machine, and belongs to the technical field of hydraulic control of logging machines. Background technique [0002] With the improvement of forestry logging safety requirements and the improvement of efficiency, more and more mechanical automation equipment is used in forestry logging occasions to improve logging efficiency and logging quality while reducing labor and ensuring logging safety. The diameters of different positions are different. When the wood is cut and measured according to the specified length, the existing mechanical automation equipment cannot measure and adjust according to the different positions of the wood, resulting in poor accuracy of the actual cut length of the wood. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provi...
