[0002] The loader bucket needs to be weighed in scenarios such as material handling and earthwork construction. The traditional loader bucket weighing method often relies on the driver's experience or a simple mechanical weighing device. This method not only has low accuracy, but is also easily affected by human factors and cannot meet the requirements of modern engineering for accuracy and efficiency. Therefore, weighing detection technology is now used. This weighing detection technology is used through a combination of sensor technology, signal processing technology and control technology. These sensors can collect the weight information of the material in the bucket in real time and accurately, and convert and transmit data through signal processing circuits to achieve accurate detection and control of the bucket weighing position.

[0025] The movable member 4 includes a fixed rod 8 fixedly mounted on the swing arm 3, and the first sensing member 6 is movably and slidably mounted on the fixed rod 8. The position of the first sensing member 6 can be adjusted to determine the distance between the first sensing member 6 and the second sensing member 7;

[0026] The fixing member 5 includes a connecting plate 9 fixedly mounted on the loader body 1 , and the second sensing member 7 is fixedly mounted on the connecting plate 9 . The connecting plate 9 can be fixed on the loader by welding or bolting.

[0027] The fixing rod 8 is provided with threads, so that the fixing rod 8 becomes a threaded rod, and the first sensing element 6 is threadedly installed on the fixing rod 8. By rotating the first sensing element 6, the position of the first sensing element 6 on the fixing rod 8 can be adjusted.

[0028] Since the loader generates vibrations during operation, the first sensing member 6 may be easily rotated, and the position of the first sensing member 6 may deviate. Nuts 10 on the threaded mounting fixing rods 8 are provided on both sides of the first sensing member 6, and the position of the first sensing member 6 can be fixed by the nuts 10.

[0029] A gasket 11 slidably mounted on the fixing rod 8 is also provided between the nut 10 and the first sensing element 6 .

[0030] The movable part 4 further comprises a fixed base 12 , which can be fixedly mounted on the swing arm 3 by welding, and the fixing part 5 is fixedly or detachably mounted on the fixed base 12 .

[0031] The first sensing element 6 includes a magnetic block, and the second sensing element 7 includes at least one Hall sensor installed on the connecting plate 9. The first sensing element 6 and the second sensing element 7 can also be a single sensor.

[0032] The magnetic block is wrapped with a protective cover 13, and the magnetic block is installed on the fixed rod 8 through the protective cover 13.

When the bucket 2 is filled with corresponding materials, the driver will control the swing arm 3 to rise to a stable position through the hydraulic cylinder. During the rising process of the swing arm 3, the first sensing element 6 and the second sensing element 7 are close to each other and trigger the weighing device to start working. When the material in the bucket 2 needs to be unloaded, the swing arm 3 will descend. During the descent of the swing arm 3, the weighing device will be triggered again and the weighing device will be closed at this time.

[0039] 3. The design takes into account the vibration problem when the loader is working. By setting nuts on both sides of the first sensing element to fix its position, and using a protective cover and a protective shell to protect the magnetic block and the Hall sensor, the stability and durability of the overall structure are increased, and it is also convenient to disassemble the first sensing element and the second sensing element for maintenance.
