Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, specifically to a material level detection device and a bulk material conveying equipment. Background Technology

[0002] Large equipment such as ship loaders and stacker-reclaimers are used for loading, unloading, and stacking materials such as coal and iron ore. These machines are equipped with cantilever mechanisms, which typically have a pitching function. To detect the material level below the cantilever, radar, ultrasonic sensors, or other material level detection elements are usually installed at the front (head) of the cantilever. These detection elements are mounted on a metal moving frame, which is generally connected and fixed to the main steel structure of the cantilever by welding. Once the metal moving frame is fixed, the illumination direction of the material level detection elements is completely fixed and cannot be adjusted.

[0003] Because different users have different operating habits, and the material drop point will also change when the cantilever is stacking material at different pitch angles, the belt speed of the stacking cantilever changes, or the material being stacked changes, it is necessary to adjust the installation position of the material level detection device in order to adjust the direction of the sensor illumination. However, since the illumination direction of the material level detection element is completely fixed, if it is necessary to adjust the installation position, or if the belt speed changes or the type of material changes, the illumination direction of the material level detection element needs to be adjusted. This can only be done by cutting and moving the frame, adjusting the illumination direction, and then re-welding. This kind of material level detection device is difficult to adapt to the actual application requirements and is very inconvenient. Summary of the Invention

[0004] Therefore, the present invention aims to solve the problem that the irradiation direction of the material level detection element in the material level detection device of the existing stacker-reclaimer or ship loader is completely fixed and cannot be adjusted, thereby providing a material level detection device and a bulk material conveying device.
