Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material loading and unloading, in particular to a wood chip stacking device. Background Art
[0002] At present, wood is still one of the commonly used raw materials in the papermaking industry. In specific production, wood is generally stored in the form of wood chips, that is, the wood chips are piled in the storage site and form wood chip piles. When they are needed, the staff will drive the loader to load and unload and transport them.
[0003] Taking the port as an example, wood chips are piled in the form of wood chip stacks at the port's storage site. When they need to be transported, the staff drives the loader to load and unload at the bottom of the wood chip stack. During this process, the loader is continuously operating at the bottom of the wood chip stack, and the bottom of the wood chip stack will be "hollowed out". At this time, the wood chips at the top of the wood chip stack will slide to the bottom and fill the bottom space. However, in the actual operation process, due to reasons such as the wood chips being damp, only some of the wood chips can slide to the bottom of the wood chip stack, and they cannot effectively fill the missing space at the bottom. Over time, the wood chip stack will appear "convex on top and concave on the bottom", and there is a risk of collapse.
[0004] In order to solve the above problems, the staff generally use an excavator to flatten the top of the wood chip stack so that the wood chips at the top of the wood chip stack can slide down fully. Although the above traditional method can solve the problem of the wood chip stack being "convex on top and concave on the bottom", there are still the following shortcomings in the specific operation process: First, the staff needs to drive the excavator to the top of the wood chip stack first, and then operate the excavator to flatten the top of the wood chip stack by swinging the bucket up and down. Since the height of the wood chip stack is relatively high, generally 8-10 meters, operating the excavator at such a high position is difficult to operate, and there are safety hazards and a low safety factor. Second, the purchase cost of the excavator is high, which in turn increases the loading and unloading costs, and the economic benefits are low. Utility Model Content
