Automatic combined felling vehicle

Abstract

The invention relates to an automatic combined lumbering vehicle mounted on an automobile chassis, and belongs to equipment in the field of lumbering. According to the automatic combined felling vehicle, the existing manual felling efficiency is greatly improved, and the labor intensity of workers is greatly reduced. According to the automatic combined felling vehicle, dangerous high-altitude felling operation and felling operation under a high-voltage wire are completely abandoned by a felling worker. The felling machine head is controlled by a wireless remote controller to automatically clamp branches or trunks, saw off trees and automatically level the trees. And the fallen timbers are stacked by remotely controlling the crane boom. The height of the cargo boom of the lumbering truck is generally 20 meters and 24 meters, and the head of the lumbering truck is fully hydraulically controlled and is not provided with any circuit, so that branches below the high-voltage wire can be safely cleaned under the clamping of an insulating arm. And dangerous factors such as circuit electric leakage and lumbering electric shock are avoided. The remote controller specially designed for the feller is easier for felling operation.

Description

Technical Field

[0001] The present invention relates to the technical field of felling equipment, and is mainly used for pruning and felling trees on both sides of narrow urban roads, on both sides of highways, and in residential areas. It can also be used to fell tall trees in open areas. It is used for pruning and felling trees under high-voltage wires and inaccessible to aerial operations. The felling machine head of the present invention is also suitable for being installed on hydraulic excavators, off-road cranes and other equipment for felling. Background Art

[0002] At present, in China, lumberjacks mainly rely on aerial work vehicles to use chainsaws to clear trees. It is even more troublesome to prune trees under high-voltage wires. The power department generally uses hand saws with insulation functions for pruning, and sometimes power outages are required for pruning. The automated joint logging vehicle completely solves the above problems. It greatly improves the efficiency of tree pruning and logging. Lumberjacks do not need to work at heights. They only need to remotely control the equipment from a distance, avoiding heights and the risk of electric shock. Summary of the invention

[0003] The basic situation of logging at present is: in open areas, trees are directly cut by hand with chainsaws. In narrow urban roads, highways, parks and residential areas, loggers stand in aerial work vehicles and cut trees with chainsaws, while using another crane to hang branches or trunks for logging. It is even more troublesome if it is under high-voltage wires. The author has only seen electric workers trim branches with hand saws with insulating rods. The purpose of the present invention is to solve the current inefficient and dangerous logging production problems of manual logging. Using an automated combined logging vehicle to replace the heavy logging operations of aerial work vehicle + chainsaw + crane + manual + insulated hand saws can greatly improve the efficiency of pruning and logging, and greatly improve the safety of logging work.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: 1. Fully hydraulic and fully automatic felling machine head. The felling machine head is controlled by 4 hydraulic pipelines. 2 oil pipes control the rotation of the felling machine head, and 2 oil pipes automatically control the felling machine head to lift, clamp, saw, lay flat, reset, release wood and other actions.

[0005] 2. As a further solution of the present invention: because the trees to be pruned are of different thicknesses, I designed two types of felling heads, one with a maximum diameter of 355 mm, mainly used for pruning branches; the other with a maximum diameter of 505 mm, mainly for felling trunks after cutting branches and twigs. In order to quickly replace the felling heads, two quick-connection arms are pre-installed on the two felling heads, and the quick-connection arms can be quickly replaced with the main lifting arm. The hydraulic quick connector can also be quickly replaced.

[0006] 3. As a further solution of the present invention: a special wireless remote controller is designed for automated joint logging. With a wired remote control function, when the logging truck is pruning trees under high-voltage wires, it is very susceptible to electromagnetic interference. When the wireless remote control is interfered with, wired control can be used. The remote controller is compatible with both logging trucks and truck cranes. After the logging truck head is removed, the red part of the remote controller does not work and only acts as a crane.

[0007] 4. As a further solution of the present invention: the 3-bridge vehicle is designed to be a 20-meter-high felling machine; the 4-bridge vehicle is designed to be a 24-meter-high felling machine.

[0008] The beneficial effects of the present invention are: 1. The fully hydraulically controlled felling machine head is the core component of the combined felling machine. It greatly improves the efficiency and safety of felling. Climbing, hoisting, felling and stacking are completed at one time. Because the felling machine head has no electrical operating part and is remotely controlled, it is easy to achieve circuit insulation under the clamping of the insulating arm, and it is very safe to trim trees under high-voltage wires.

[0009] 2. Two specifications of felling machine heads can be quickly replaced, and the process of replacing felling machine heads is efficient.

[0010] 3. The remote control and the truck crane have high versatility. The combined felling truck can also be used as a truck crane after the felling machine head is removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0017] Specific implementation: like Figure 1 As shown, the automated combined logging vehicle comprises: a logging head (1), a quick-connect arm (2), a lifting arm and a slewing support (3), a wireless remote control (4), and a vehicle chassis (5). The logging head (1) is the core part of the automated combined logging vehicle, and is mainly used to clamp branches, twigs and trunks and cut them. The lifting arm and slewing support of the logging vehicle are used to move the logging head to a suitable position. The loggers can remotely control various actions of the logging vehicle by operating the wireless remote control to realize combined logging.

[0018] like Figure 2 As shown, the felling head of the automated combined felling vehicle includes: a slewing motor (1), a control valve group (2), a lubricating oil tank (3), a chain saw motor (4), a guide bar chain saw (5), a protective cover (6), a gripper (7), and a guide bar oil cylinder (8). Two hydraulic oil pipes passing through the boom control the rotation of the slewing motor so that the opening direction of the gripper faces the branch to be sawed off. During the alignment process, the protective cover (6) protects the guide bar from collision. Another two hydraulic oil pipes passing through the boom enter the control valve group (2) to open the gripper (7). Then, the oil circuit is reversed, and the gripper (7) clamps the wood to be sawed off, while the lubricating oil tank (3) sprays oil onto the guide bar; after clamping, the chain saw motor (4) and the guide bar oil cylinder (8) work simultaneously, and the guide bar chain saw (5) starts sawing until the wood is cut off. This is the process of realizing automatic felling by the felling head.

[0019] like Figure 3 As shown, the hydraulic principle of the felling machine head is shown.

[0020] like Figure 4 As shown in the figure, the quick-connect arm of the automated combined felling vehicle can pre-install a felling head with a diameter of 355 mm and a felling head with a diameter of 505 mm. The quick-connect arm can quickly replace the felling head to improve efficiency.

[0021] like Figure 5 As shown in the figure, the wireless remote control of the automated combined felling vehicle is a remote control specially designed for felling. The red part is convenient for right-hand operation. The rightmost rocker, when moved to the left, the felling machine head rotates counterclockwise; when moved to the right, the felling machine head rotates clockwise; the middle position is reset. Push the first gear upwards to open the felling clamp; push the second gear upwards to lift the felling clamp 90°. Push the first gear downwards to clamp the felling clamp; push the second gear downwards to start felling. During normal felling operation, in order to improve felling efficiency, whether it is upward or downward, push directly to the second gear, and the felling machine head will automatically work in sequence. After the saw function switch is disconnected, the felling machine head can only be used as a clamp for loading and unloading wood.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
