Detecting and metering device for wood

Abstract

The invention discloses a detecting and metering device for wood. The detecting and metering device comprises a wood storage tank, a wood conveying device and a detection device, wherein the wood storage tank is provided with a wood outlet along the length direction of the wood; the wood conveying device is used for conveying the wood such as log from the wood outlet to a detection area; the detection device is used for detecting the length and the section areas of two ends of the wood passing through the detection area; the wood conveying device comprises a plate type conveyor and a chain type conveyor which are adjacently arranged along the conveying direction of the wood; the plate type conveyor is arranged close to the wood storage tank; the conveying speed of the chain type conveyor is higher than that of the plate type conveyor; the height of a conveying surface of the chain type conveyor is smaller than that of a conveying surface of the plate type conveyor. According to the detecting and metering device disclosed by the invention, two adjacent woods falling on the chain type conveyor can be enabled to be arranged at a certain interval; in addition, each log falls on one section of chain not between two sections of chains, so that a sorting beat of the plate type conveyor still can meet the detection beat of the chain type conveyor, the phenomenon that the whole conveying line is blocked is avoided, more accurate measurement data are obtained and the detection efficiency is increased.

Description

technical field [0001] The invention relates to the field of wood volume measurement, in particular to a detection and measurement device for detecting logs. Background technique [0002] With the rapid development of my country's foreign trade and economy, the demand for logs for infrastructure construction and logs for production and living remains high. In 2011, my country's customs ports and land ports imported about 40 million m3 of logs, showing an upward trend year-on-year. Volume measurement of such a large number of logs is a big problem. For a long time, the method of measuring the volume of logs in China has mainly been manual inspection, that is, inspectors use manual inspection tools such as rulers, calipers, and tape measures to detect the volume of logs. This method has harsh working environment, high work intensity, long detection cycle, low efficiency, large error, and low reliability. The results of volume detection are greatly affected by subjective fact...

But obviously, this method of calculating the volume of wood is only a rough estimate. It can neither measure the real volume of wood loaded in the compartment, nor can it calculate how many pieces of wood are in the compartment. More importantly, this detection The system cannot detect the timber piled up at customs gates and port terminals
