Fully automatic discharge spreader

Abstract

This utility model belongs to the field of dump truck technology, and in particular to a fully automatic unloading spreader, including a dump truck body and a spreading device. The dump truck body consists of power and hydraulic system components, protective and body structure components, electrical and lighting system components, and functional and special devices. The spreading device includes subframe longitudinal beams A and B installed inside the dump truck body. This utility model, by installing a spreading device inside the dump truck body, uses continuous chain transmission to smoothly transfer the loaded heavy load outside the vehicle, avoiding the impact and damage that may be caused by large pieces of material falling due to gravity, and avoiding the center of gravity shift problem of traditional bucket unloading. This improves operational efficiency while further ensuring operational safety under complex road conditions. Simultaneously, the spreading device can be flexibly adapted to the spreading of granular materials such as de-icing agents and anti-skid sand, as well as the transfer of ordinary garbage and construction waste, thus enhancing the functionality of the spreading device.

Description

Technical Field

[0001] This utility model relates to the field of dump truck technology, specifically to a fully automatic unloading spreader. Background Technology

[0002] Traditional dump trucks require a hydraulic system to lift the cargo bin to a certain angle before unloading, relying on the material's own weight. However, during the lifting process, the vehicle's center of gravity shifts significantly upwards along with the position of the bin and its contents. This lifts weight that was originally distributed at the bottom of the vehicle, disrupting its stability. In such cases, uneven road surfaces (such as potholes, slopes, or protruding gravel) can cause significant differences in the support forces on both sides of the vehicle. This risk is further amplified when the material in the bin is unevenly loaded or when the center of gravity suddenly shifts during unloading, potentially damaging the vehicle and posing a serious safety threat to nearby personnel and equipment. Therefore, we propose a fully automatic unloading spreader to address these issues. Utility Model Content
