Abstract

The invention discloses an electric control device of a small-sized loader. The electric control device of the small-sized loader at least comprises a bucket, a loader body, an operating mechanism and a lifting mechanism of the small-sized loader, wherein the bucket is connected with the loader body through lifting arms, the lifting arms comprise a left arm, a middle arm and a right arm, and movable joints are arranged on the left arm, the middle arm and the right arm. The electric control device of the small-sized loader is characterized in that the left arm, the middle arm and the right arm are respectively connected with an electric cylinder telescopic arm, an electric cylinder is fixed with the loader body, and the electric cylinder is electrically connected with the operating mechanism. The electric control device of the small-sized loader solves the technical problems that an existing loader driving system is inconvenient to install, low in transmission efficiency, short in service life, large in running noise, and low in reliability.

Description

technical field [0001] The invention relates to a small loader, in particular to an electric control device for a small loader. Background technique [0002] The bucket of the loader is connected to the loader body through the lifting arm. The lifting arm is composed of left, middle and right arms. There are movable joints on the left, middle and right arms. The control mechanism controls the expansion and contraction of the three oil cylinder mechanisms to lift, lower and turn the bucket. [0003] But the existing hydraulic system has the following problems: [0004] 1. The connection of the hydraulic pipeline is complex and prone to oil leakage and the installation of the system is inconvenient. [0005] 2. The efficiency of hydraulic transmission is low, so battery forklifts generally use a separate motor to drive the hydraulic pump. Due to the working principle and manufacturing process of the hydraulic pump, the working efficiency of the system is low, resulting in w...
