Abstract

The utility model discloses an automatic leveling device for a loader, which comprises an angle sensor, a poking plate, a poking rod and a protective cover. The angle sensor comprises a rotating shaft and a main body, wherein the main body is fixed in a protective cover, and the protective cover is connected with the front frame. The plectrum adopts a platy structure, one end of the plectrum is fixedly connected with the sensor rotating shaft through a through hole, and the other end of the plectrum is provided with an empty slot; the deflector rod is fixed on the movable arm, the bolt is movably connected with the empty slot of the poking piece. When the sensor is in operation, the movable arm moves to drive the deflector rod to swing, and the deflector plate is driven to rotate through the cooperation of the bolt and the empty slot, so that the sensor rotating shaft rotates, and the mechanical displacement is converted into an electric signal. The control system adjusts the bucket angle in real time according to the sensor signals, and the automatic leveling function is realized.

Description

Be used on loader automatic leveling device of (a) Technical Field The utility model relates to the technical field of loaders, in particular to an automatic leveling device for a loader. Background In the working process of the loader, the leveling operation of the bucket is a key step of a material loading and unloading and transferring link. The leveling of a conventional loader bucket is determined based on experience of an operator, and is adjusted by manually manipulating a hydraulic valve or lever by observing the relative position of the bucket to the ground. However, due to the difference between the technical level and visual judgment of operators, the consistency of each operation is difficult to ensure due to the flat angle of the bucket, and the material leakage or the bucket inclination is easy to cause, so that the loading and unloading efficiency and the operation quality are affected. Meanwhile, operators need to repeatedly adjust the posture of the bucket, fatigue is easily caused by long-time operation, the working efficiency is reduced, and potential safety hazards are possibly caused by misoperation. Currently, some loaders on the market are equipped with mechanical or sensor-assisted leveling devices, for example, by means of tilt sensors in combination with hydraulic control systems, to achieve a semi-automatic leveling function. However, these devices still have some problems. For example, mechanical structures are susceptible to vibration and wear, frequent replacement not only greatly increases the cost of use, but also long-term wear can result in accumulation of detection errors, thereby reducing the reliability thereof. In addition, the existing sensor scheme is easy to be disturbed under complex working conditions, and accurate signals are difficult to continuously and stably output. Disclosure of utility model In order to solve the defects in the prior art, the utility model provides an automatic leveling device for a loader, which comprises an angle sensor, a plectrum, a deflector rod and a protective cover, wherein the angle sensor is arranged on the deflector rod; The angle sensor comprises an angle sensor rotating shaft and an angle sensor main body, the angle sensor main body is fixedly arranged on the protective cover, and the protective cover is fixedly connected with the front frame; the poking piece is of a plate-shaped structure, a circular through hole matched with the rotating shaft of the angle sensor in shape is formed in the center of one end of the poking piece, and an empty slot is formed in the other end of the poking piece; One section of the deflector rod is fixedly arranged on the movable arm, the other end of the deflector rod is provided with a bolt, and the bolt is movably connected with the empty slot. Compared with the prior art, the utility model has the beneficial effects that: According to the utility model, the angle of the movable arm is monitored in real time through the angle sensor, and the physical displacement is converted into an accurate electric signal by combining the mechanical linkage structure of the shifting sheet and the shifting rod, so that the automatic feedback and adjustment of the bucket angle are realized. Meanwhile, the automatic operation flow reduces the labor intensity of operators, does not need continuous manual fine adjustment, is particularly suitable for long-time and high-strength operation scenes, and effectively improves the overall working efficiency of the loader. The angle sensor and the mechanical triggering structure work cooperatively, the sensor part is fixed in the protective cover and is free from the influence of external environments such as dust, rain and the like, and the flexible connection design of the poking sheet and the poking rod ensures flexibility and avoids abrasion risk caused by rigid connection through the cooperation of the bolt and the empty groove. The cover of the protective cover further protects key mechanical parts and prolongs the service life of the device.
