Description

Technical Field

[0001] The utility model relates to the technical field of wood chip unloaders, in particular to a full-automatic wood chip unloader. Background Art

[0002] Large paper manufacturing companies usually purchase bulk wood chips as their main raw material. Since wood is generally distributed in mountains, forests and hills, a large part of the transportation of wood chips is by car.

[0003] Traditionally, the unloading of wood chips transported by trucks is entirely manual, that is, after the truck enters the fixed unloading point and opens the compartment, a large flat plate modified from the loader's forearm is used to push the wood chips off the compartment. After the wood chips are unloaded, the samplers enter the site to take samples. This sampling method has high safety risks. There are loaders going back and forth, trucks passing back and forth, and samplers working on foot. In addition, the wood chips stored on site block the view like a hill. Every day, dozens or even hundreds of wood chip transport trucks deliver and unload in the wood chip yard. After each truck unloads the wood chips, the wood chip samplers have to carry locked buckets, wear camera helmets, hold sampling shovels, and wear luminous vests like soldiers charging. They must immediately enter the hill-like wood chip yard for timely sampling. If the vehicle driver is not careful, a safety accident may occur.

[0004] A pulp and paper company purchases hundreds of thousands to millions of tons of wood chips each year. Traditional manual on-site unloading requires two shifts (day shift and mid-shift, with one full-time driver for each shift), and on-site operations are required regardless of wind, rain, snow, severe winter or hot summer. This purely manual sampling operation is inefficient, with long working hours and high labor intensity, and great safety risks. The company also needs to purchase expensive loaders and equip full-time drivers, as well as pay for the expensive loader's full life cycle maintenance costs and human resource costs, which is time-consuming, costly and labor-intensive.

[0008] Support beams are welded on both sides of the outer wall at the top of the unloading platform, and an escalator body is welded between the two support beams, and the steel platform is arranged at the bottom of the escalator body.

[0009] Preferably, the escalator body includes a bottom escalator, a middle escalator and a top platform, and the bottom escalator, the middle escalator and the top platform are welded to each other.

[0010] Preferably, a truck body is placed on the top outer wall of the steel platform, and a wood chip storage bin is provided inside the compartment of the truck body.

[0011] Preferably, a bottom groove is provided on the top outer wall of the unloading platform, and the size of the bottom groove is adapted to the size of the steel platform.
