Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of excavators, in particular to an excavator bucket arm recovery accelerator. Background Art
[0002] The excavator boom refers to an important part of the excavator used to connect the bucket (such as bucket, digging bucket, etc.), also known as the arm. The boom is generally made of steel and has a certain strength and durability. It is used to support and operate the bucket for excavation, loading and other tasks. Its movement is usually controlled by a hydraulic system. The excavator boom recovery accelerator is a device that quickly recovers the hydraulic oil of the excavator.
[0003] When the existing excavator boom is recovered, the recovery speed of the hydraulic oil directly affects the operating efficiency and performance of the excavator boom. The hydraulic oil recovery speed is not fast enough, which affects the recovery speed of the excavator boom. For this reason, we propose an excavator boom recovery accelerator. Utility Model Content
[0004] The utility model aims to provide an excavator bucket arm recovery accelerator to solve the technical problem of slow hydraulic oil recovery speed proposed in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an excavator boom recovery accelerator, comprising an accelerator body, an A interface installed on the accelerator body, a B interface provided on the accelerator body, and the B interface is symmetrically arranged with the A interface, a C interface is provided on the side of the accelerator body, a D interface is installed on the accelerator body, and the D interface is located on one side of the B interface, a regeneration valve corresponding to the D interface is installed inside the accelerator body, an E interface is provided inside the accelerator body, and the E interface is located on one side of the D interface, a regeneration cut-off valve corresponding to the E interface is installed on the accelerator body, a pipeline is provided inside the accelerator body, and the pipeline connects the A interface, the B interface, the C interface, the D interface and the E interface.
[0006] Preferably, the A interface is connected to the small chamber of the boom cylinder.
[0007] Preferably, the B interface is connected to an excavator distributor.
[0008] Preferably, the C interface is a regeneration port connected to the large chamber of the oil cylinder.
[0009] Preferably, the D interface is connected to the pilot of the boom recovery to control the operation of the regeneration valve.
[0010] Preferably, the E interface is connected to the large chamber of the oil cylinder to control when the regeneration is cut off.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The utility model installs the A interface, which facilitates the excavator arm recovery accelerator to quickly recover the hydraulic oil. When the excavator arm recovery accelerator is used, the hydraulic oil inside the small cavity of the arm cylinder directly flows to the B interface through the A interface when the handle does not have a full stroke. When the full stroke is reached, the hydraulic oil inside the small cavity of the arm cylinder flows to the C interface through the A interface, and then enters the large cavity of the cylinder, thereby speeding up the recovery speed. When the arm is digging, the regeneration cut-off valve will open, allowing the hydraulic oil to flow directly to the B interface to the distributor, thereby speeding up the recovery speed of the excavator arm.

When using the excavator boom recovery accelerator, when the handle does not have a full stroke, the hydraulic oil inside the small chamber of the boom cylinder flows directly to the B interface 3 through the A interface 2. When the full stroke is reached, the hydraulic oil inside the small chamber of the boom cylinder flows to the C interface 4 through the A interface 2, and then enters the large chamber of the cylinder, thereby speeding up the recovery speed. When the boom is digging, the regeneration cut-off valve 7 will open, allowing the hydraulic oil to flow directly to the B interface 3 to the distributor, thereby speeding up the recovery speed of the excavator boom.
[0019] Working principle: first, when using the excavator boom recovery accelerator, when the handle does not have a full stroke, the hydraulic oil inside the small cavity of the boom cylinder flows directly to the B interface 3 through the A interface 2. When it is in full stroke, the hydraulic oil inside the small cavity of the boom cylinder flows to the C interface 4 through the A interface 2, and then enters the large cavity of the cylinder, thereby speeding up the recovery speed. When the boom is digging, the regeneration cut-off valve 7 will open, allowing the hydraulic oil to flow directly to the B interface 3 to the distributor, thereby speeding up the recovery speed of the excavator boom.
