Description

Technical Field

[0001] This utility model relates to the technical field of loaders, and in particular to an automatic bucket leveling mechanism for wheel loaders. Background Technology

[0002] Loaders are a type of earthmoving construction machinery widely used in highway, railway and other engineering projects. They are mainly used for various soils, sand and gravel, ash and other bulk materials for road construction, and are mainly used for shoveling, loading, transporting and unloading.

[0003] Existing automatic leveling mechanisms for loader buckets, such as the automatic leveling device for loader buckets disclosed in utility model patent application number 201721590863.4, mainly include a leveling indicator rod fixed to the piston rod of a hydraulic cylinder, with an internal guide rail for movable assembly with a slider. The right end of the slider is fixed to the indicator rod fixing bracket, which is fixed to the cylinder barrel of the reversing hydraulic cylinder. In use, the piston rod of the hydraulic cylinder drives the leveling indicator rod to move to the right, while the cylinder barrel remains stationary. This creates a movement process where the sensing plate approaches the proximity switch. When the sensing plate blocks the proximity switch, the piston rod of the hydraulic cylinder stops moving, and the bucket is in a horizontal position.

[0004] However, existing loaders generally work outdoors, and the existing leveling mechanisms are mostly exposed, making them easy to get dusty or damaged, which affects the lifespan of the equipment. Moreover, most existing leveling mechanisms are simple and rely solely on indicator rods to determine whether the load is level, which can easily lead to misjudgments. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic bucket leveling mechanism for wheel loaders that not only protects the relevant equipment from mud and dust affecting its normal operation and extending its service life, but also uses an angle sensor to assist in detecting whether the bucket is level, thus preventing the device from misjudging.

[0006] This utility model discloses an automatic bucket leveling mechanism for a wheel loader, including a bucket mechanism; it also includes a protective mechanism, a leveling mechanism, and a detection mechanism. The protective mechanism is installed on the bucket mechanism to prevent soil from hitting the leveling mechanism. The leveling mechanism is installed on the protective mechanism to detect whether the bucket is level. The detection mechanism is installed on the bucket mechanism to assist in detecting whether the bucket is level. During the loader's shoveling process, the protective mechanism protects the leveling mechanism from soil damage. After shoveling is completed, the leveling mechanism detects whether the bucket is level, and the detection mechanism assists the leveling mechanism in detecting whether the bucket is level.

[0007] Preferably, the bucket mechanism includes a bucket cylinder, a connecting seat, and a bucket body. The bucket cylinder is mounted on a wheel loader, the connecting seat is rotatably mounted on the piston rod of the bucket cylinder, and the connecting seat is mounted on the bucket body. The bucket cylinder adjusts the angle of the bucket body through the connecting seat to facilitate the bucket body's scooping of soil.

[0008] Preferably, the protective mechanism includes a column, a protective plate, and a protective box. The column is installed at the front end of the bucket cylinder, the bottom end of the protective plate is connected to the top end of the column, and the protective box is installed at the rear end of the bucket cylinder. By setting the protective plate and the protective box, soil falling and damaging the leveling mechanism is prevented, thus protecting the leveling mechanism. At the same time, the driver can judge whether the bucket body is level based on the relative distance between the protective plate and the protective box. When the protective plate and the protective box are about to overlap, the bucket is in a horizontal state.

[0009] Preferably, the protective plate is made of ultra-high molecular weight polyethylene (UHMWPE); UHMWPE has an extremely low coefficient of friction, good anti-adhesion properties, which can reduce material adhesion, and its light weight can reduce equipment energy consumption and protect areas not directly impacted.

[0010] Preferably, the leveling mechanism includes a receiver, a sensor, a fixing ring, and a telescopic sleeve. The receiver is installed inside the protective box, the sensor is installed on the column, the fixing ring is installed on the sensor, and the telescopic sleeve is connected and installed between the fixing ring and the protective box. By setting the fixing ring and the telescopic sleeve, dust is prevented from entering the receiver, ensuring the contact effect between the receiver and the sensor. When the sensor is inserted into the receiver, the driver is notified by an electrical signal to lock the length of the bucket cylinder.

[0011] Preferably, the receiver also includes a guide groove at the top; by setting the guide groove, it is easier for the sensor to be inserted into the receiver, improving the fault tolerance of the device and preventing the receiver and sensor from getting stuck.

[0012] Preferably, the detection mechanism includes two sets of connecting pins, two sets of linkage shafts, and an angle sensor. Both sets of connecting pins are rotatably mounted on the bucket body, and the two sets of linkage shafts are respectively connected to the two sets of connecting pins. The angle sensor is mounted on the bucket body. The boom of the loader drives the two sets of connecting pins to rotate, and the two sets of connecting pins drive the two sets of linkage shafts to rotate. The angle sensor detects the rotation angle of the two sets of linkage shafts, which can not only help determine whether the bucket body is level, but also detect whether the left and right ends of the bucket body are tilted.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: during the loader's shoveling process, the protective mechanism protects the leveling mechanism to prevent soil from damaging the leveling mechanism. After shoveling is completed, the leveling mechanism checks whether the bucket is level. The detection mechanism assists the leveling mechanism in checking whether the bucket is level.
