Abstract
Perseverance agricultural machinery oil cylinder of the throttling with filtering, including port connection, throttling chamber is set between the linkage section of port connection and logical oil section, and the linkage section of port connection is threadedly coupled with articulated joint, and throttling pad is installed in throttling chamber；The oil inlet of articulated joint is provided with filter screen.This agricultural machinery oil cylinder constitutes throttling chamber using the gap between this body structure of port connection and articulated joint, and throttling pad is installed in throttling chamber, can not only reach the effect of stabilization throttling, and reduces amount of parts, saves installing space；The connection of articulated joint and outer oil circuit oil pipe can also be on collocation structure connection.
Description
Technical field
The present invention relates to a kind of agricultural machinery oil cylinder, specifically a kind of permanent agricultural machinery oil cylinder of the throttling with filtering.
Background technology
Agricultural machinery oil cylinder needs at the uniform velocity operation and overload protection due to its special operating mode and use demand in operation process
Flow is controlled, and often built-in balanced valve and choke valve meet use requirement to oil cylinder.For severe use environment, in order to ensure oil circuit
Cleaning, the use of valve is not influenceed and is used, it is necessary to install the normal of screen pack guarantee work fluid.Choke valve is typically mounted at cylinder
In base oil road, or in port connection, both mounting means are required to take enough spaces.Manufacture for convenience and make
With, choke valve and balanced valve are often installed on cylinder bottom, choke valve is arranged in joint, and such joint height and installing space are all
Can increase, cause whole oil cylinder volume to increase.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of permanent agricultural machinery oil cylinder of the throttling with filtering, should
Agricultural machinery oil cylinder can accomplish uniform flow control, on the premise of service condition is met, greatly reduce installing space；Structure letter
It is single, working stability, it is easy to safeguard, installing/dismounting is more convenient.
In order to solve the above technical problems, the present invention provides a kind of permanent agricultural machinery oil cylinder of the throttling with filtering, including port connection,
Port connection is welded on cylinder body, and throttling chamber, the linkage section of port connection are set between the linkage section of port connection and logical oil section
It is threadedly coupled with articulated joint, throttling is provided with throttling pad in chamber；The oil inlet of articulated joint is provided with filter screen.
For the sake of for simple declaration problem, below to permanent agricultural machinery oil cylinder of the throttling with filtering of the present invention referred to as originally
Agricultural machinery oil cylinder.
This agricultural machinery oil cylinder cancels traditional choke valve, uses throttling pad instead, using port connection structure in itself with it is external
Gap between articulated joint constitutes throttling chamber, installs throttling pad in throttling chamber, regulation throttle clearance and throttle orifice it is big
The small regulation for completing flow, reduces the manufacturing cost of oil cylinder.Ingenious use respective outer side edges gap, is meeting the feelings of use requirement
Under condition, design space is saved, make cylinder structure compacter；In order to ensure the cleannes of oil cylinder inner fluid, in articulated joint
Oil inlet installs screen pack, filters the impurity in fluid.The assembling of this agricultural machinery oil cylinder is simpler, significantly improves assembling effect
Rate, articulated joint can meet the micro-adjustment that structure is installed, and be made moderate progress with the installation of outer oil circuit for whole oil cylinder.
In a word, this agricultural machinery oil cylinder constitutes throttling chamber using the gap between this body structure of port connection and articulated joint,
Throttling pad is installed in throttling chamber, the effect of stabilization throttling can be not only reached, and reduces number of components, save installation
Space；The connection of articulated joint and outer oil circuit oil pipe can also be on collocation structure connection.
The internal diameter that the internal diameter in chamber that throttles is more than the internal diameter for leading to oil section and is less than linkage section, can facilitate and be put into throttling pad
Throttling chamber, moreover it is possible to avoid throttling pad from being dropped out from throttling chamber.
Brief description of the drawings
Fig. 1 is the structural representation of permanent agricultural machinery oil cylinder of the throttling with filtering of the invention.
Fig. 2 is the schematic diagram of the port connection of permanent agricultural machinery oil cylinder of the throttling with filtering of the invention.
Specific embodiment
Invention is described further below by the drawings and specific embodiments.
The agricultural machinery oil cylinder that perseverance throttling band is filtered, as shown in Figure 1 and Figure 2, including port connection 4, port connection 4 is welded on agriculture
At the oil inlet of Oil cylinder M, throttling chamber 42 is set between the linkage section 41 of port connection 4 and logical oil section 43, throttle the interior of chamber 42
Footpath is less than the internal diameter of linkage section 41, linkage section 41 and the spiral shell of high pressure articulated joint 1 of port connection 4 more than the internal diameter of logical oil section 43
Line is connected, and throttling pad 3 is provided with throttling chamber 42；The oil inlet of high pressure articulated joint 1 is provided with filter screen 2, for entering
Fluid in oil cylinder M is filtered, the impurity in oil strain liquid.
Above-described is only one embodiment of the present invention, it is noted that for one of ordinary skill in the art
For, under the premise without departing from the principles of the invention, some variations and modifications can also be made, for example throttle pad 3 and filter screen 2
Change of fixed form of change, throttling pad 3 and filter screen 2 of size and location etc., these also should be regarded as belonging to of the invention
Protection domain.
