Abstract
To measure the weight of an excavated object, with a simple configuration at low cost, a scraper vehicle includes a coupler having a first portion to be coupled to a driving vehicle and a first detection device provided at at least one of the first portion of the coupler and a first supporting member that supports the first portion. The first detection device is configured to detect a variation in a physical quantity of the first portion.
Claims20
A scraper vehicle configured to move with a driving vehicle, the scraper vehicle comprising:
- a coupler having a first portion to be coupled to the driving vehicle;
- a first detection device provided on at least one of the first portion of the coupler or a first supporting member that supports the first portion, wherein the first detection device is configured to detect a variation in strain of the first portion and the first portion and the first supporting member support a part of a weight of an excavated object loaded on the scraper vehicle;
- and
- a calculation device configured to calculate the weight of the excavated object loaded on the scraper vehicle, based on the variation in strain detected by the first detection device and a load acting on the first portion.
A scraper vehicle configured to move with a driving vehicle, the scraper vehicle comprising:
- a coupler having a first portion to be coupled to the driving vehicle;
- a first detection device provided on at least one of the first portion of the coupler or a first supporting member that supports the first portion, the first detection device being configured to detect a variation in strain of the first portion;
- a second detection device provided at a second supporting member that supports an axle of the scraper vehicle, the second detection device being configured to detect a variation in a load acting on the second supporting member;
- and
- a calculation device configured to calculate a weight of an excavated object loaded on the scraper vehicle, based on the variation in strain detected by the first detection device, and wherein the calculation device is configured to calculate a ratio between a load acting on the first supporting member and the load acting on the second supporting member, based on a result of the detection by the first detection device and a result of the detection by the second detection device.
A scraper vehicle configured to move with a driving vehicle, the scraper vehicle comprising:
- a coupler having a first portion to be coupled to the driving vehicle;
- and
- a first detection device provided on at least one of the first portion of the coupler or a first supporting member that supports the first portion, wherein the first detection device is configured to detect a variation in strain of the first portion,
- wherein the first detection device performs the detection with a known weight loaded on the scraper vehicle while the scraper vehicle is moving;
- and
- a calculation device configured to calculate the weight of the known weight loaded on the scraper vehicle, based on the variation in strain detected by the first detection device and a load acting on the first portion.
