Abstract

A kind of harvester crane hydraulic system, with 5-linked valve, the bidirectional hydraulic lock of first connection grab bucket clamping cylinder front end of the 5-linked valve, the bidirectional hydraulic lock of second connection forearm telescopic oil cylinder front end, the hydraulic lock of 3rd connection large arm support cylinder front end, the bidirectional hydraulic lock of tetrad connection armstand rotary oil cylinder front end, 5-linked connection grab bucket rotation motor.Its advantage is that harvester crane is controlled using hydraulic system, easy to use, reliable operation.

Description

Harvester crane hydraulic system
Technical field
The present invention relates to harvester crane technical field, more particularly to a kind of harvester crane hydraulic system.
Background technology
Chinese patent 200680004736.X discloses a kind of harvester crane, and it includes passing through pedestal and rotating device The boom arm sections being attached in chassis machine, the wherein boom arm sections include:The master that pedestal is pivotally connected under at lower end hangs Arm;The school for mainly extending its path forward with the opposite end that main arm is connected to by upper pivot axis and from main arm connects arm; Manipulate the manipulation device of arm, i.e. lifting device and transfer device.The lower pivot of main arm is located near rotating device Bottom, pedestal are in fork-shaped, and underarm and lift cylinder are at least partially disposed at this kind of cranes of in pedestal and used in such as forestry machinery In mobile and processing timber or whole strain timber.But in the invention without open hydraulic system.
The content of the invention
It is an object of the invention to provide a kind of harvester crane hydraulic system realized harvester crane and be controlled.
The solution of the present invention is such：
A kind of harvester crane hydraulic system, there is 5-linked valve, the first connection grab bucket clamping cylinder front end of the 5-linked valve Bidirectional hydraulic lock, the bidirectional hydraulic lock of the second connection forearm telescopic oil cylinder front end, before the 3rd connection large arm support cylinder The hydraulic lock at end, the bidirectional hydraulic lock of tetrad connection armstand rotary oil cylinder front end, 5-linked connection grab bucket rotation motor.
It is an advantage of the invention that harvester crane is controlled using hydraulic system, easy to use, reliable operation.
Brief description of the drawings
Fig. 1 is the hydraulic scheme of the present invention.
Reference is in figure：Bearing 1, armstand rotary oil cylinder 2, armstand 3, large arm support cylinder 4, large arm 5, forearm stretch Oil cylinder 6, forearm 7, grab bucket rotation motor 8, grab bucket 9, grab bucket clamping cylinder 10,5-linked valve 11, hydraulic motor 12, hydraulic oil container 13。
Embodiment
The present invention is as shown in figure 1, have 5-linked valve 11, before the first connection grab bucket clamping cylinder 10 of the 5-linked valve 11 The bidirectional hydraulic lock at end, the bidirectional hydraulic lock of the front end of the second connection forearm telescopic oil cylinder 6, the 3rd connection large arm support cylinder The hydraulic lock of 4 front ends, the bidirectional hydraulic lock of the front end of tetrad connection armstand rotary oil cylinder 2,5-linked connection grab bucket rotation motor 8。
During work, bearing 1 can be installed in mobile or fixed equipment.Armstand 3 is installed in bearing 1, relative can be turned Dynamic, armstand rotary oil cylinder 2 can control armstand 3 to rotate.Large arm support cylinder 4 can control large arm to rotate 5.Forearm telescopic oil cylinder 6 can Forearm 7 is controlled to be rotated relative to the end of large arm 5.Grab bucket rotation motor 8 can be such that grab bucket 9 is rotated relative to forearm 7.Grab bucket clamps oil Cylinder 10 can make the pawl folding in grab bucket.
High pressure liquid is obtained from hydraulic oil container 13 to press oil, can control each oil cylinder to stretch by 5-linked valve 11 by hydraulic motor 12 Contracting and hydraulic motor rotating, to realize the work of each several part.
