Embodiment 1

[0023] Such as figure 2 The shown double-winch and double-cable circular reverse-slope logging method for steep mountainous terrain includes the following steps:

[0024] Step 1: Drive the double winch skidding tractor 4 to the forest road 1 above the cutting area, select the anchor wood Ⅰ 2 in front of the double winch skidding tractor 4 to fix the double winch skidding tractor 4, and then use the mandrel 3 to set the double winch Timber tractor 4 is anchored;

[0025] Step 2: Two winches are installed at the tail of the double-winch skidding tractor 4, and the corresponding reels of the two winches are respectively wound around the fixed end of the traction cable I5 and the fixed end of the traction cable II6, and the two reels can be independently controlled Forward and reverse rotation and idling;

[0026] Step 3: Select the anchor wood II7 at the rear and lower part of the skidding tractor 4 with double winches as the first fulcrum of the cable, and fix and install two...

Embodiment 2

[0033] The difference between this embodiment and Example 1 is that: the anchor wood I2, the anchor wood II7, the anchor wood III9 and the anchor wood IV15 are all cut roots.

Embodiment 3

[0035] The difference between this embodiment and embodiment 1 lies in that: the wooden binding cable I12 and the wooden binding cable II18 are respectively connected to the iron ring I11 and the iron ring II17 through hooks.

Abstract

The invention discloses a double-winch double-cable circulation adverse slope logging method for a steep mountain. The method comprises the following steps of driving a double-winch logging tractor toa forest road to be anchored; selecting three anchoring woods II, III and IV as three fulcrums of a cable, sequentially mounting two corresponding guide pulleys I, two corresponding guide pulleys IIand one corresponding guide pulley III on the anchoring woods II, III and IV, and enabling the cable end of a traction cable I and the cable end of a traction cable II to sequentially bypass the two guide pulleys I and the two guide pulleys II respectively; enabling one end of a haul-back cable to connect with the cable end of the traction cable I through an iron ring I, and the other end of the haul-back cable to bypass the guide pulley III so as to connect with the cable end of the traction cable II through an iron ring II, thereby forming a closed cable through the traction cable I, the traction cable II and the haul-back cable; and moving the two ends of the haul-back cable up and down on a forest road and a wood collecting point to transfer wood under the recycling effect of the traction cable I or the traction cable II.

Description

technical field [0001] The invention belongs to the technical field of wood-collecting in forest areas, and in particular relates to a double-winch and double-cable circulation reverse slope wood-collecting method in steep mountainous areas. Background technique [0002] With the continuous advancement of the forestry mechanization process, more and more forestry machinery began to enter the forest area to participate in forestry production activities, which is of great significance for reducing the labor intensity of forestry workers, improving forestry production efficiency, and promoting the sustainable development of forestry production. Logging and transportation in steep mountainous forest areas is one of the most labor-intensive and difficult production links in forestry production. In order to reduce the labor intensity of logging on the reverse slope and improve the efficiency of logging in some forest areas, a tractor is widely used. A cable skidding machine equipp...
