Abstract
Abstract A combination to determine the weight of the contents of a bucket (15) of an excavator having an articulated arm (10), the weight of the contents can be calculated if the angle between the two arms (13, 14) of the articulated arm can be determined together with the pressure within the hydraulic ram 16 which pivots the base arm (13) of the articulated arm (10).

A combination to determine the payload of a bucket of an articulated arm (10) with the bucket (15) adapted to receive powder or particulate matter, said arm including a base arm (13) to be pivotally attached at one end to a prime mover (11), a first hydraulic ram (16) extending between the prime mover (11) and said arm (13) to cause pivoting of said arm (13) relative to said prime mover (11), a link (14) pivotally attached at one end to the other end of said arm (13) relative to said prime mover (11), a second hydraulic ram (17) extending between said base arm (13) and link (14) so as to pivotally move said link (1 4 ) relative to said base arm (13), a bucket (15) pivotally attached to the other end of said link (14) relative to said base arm (13), a third hydraulic ram (18) extending between said link (14) and said bucket (15) to pivotally move said bucket (15) relative to said link (14), first angle detection means to detect the angle between said base arm (13) and link (14), means to determine the hydraulic pressure in the first hydraulic ram (16) to thereby determine the force applied to said base arm (13) by said first hydraulic ram (16), and means to calculate the weight of the contents in said bucket (15) by receiving information from said first detection means and the means to detect the pressure in said_first hydraulic ram (16).

A combination to determine the payload of a bucket of an articulated arm (10) with the bucket (15) adapted to receive powder or particulate matter, said arm including a base arm (13) to be pivotally attached at one end to a prime mover (11), a first hydraulic ram (16) extending between the prime mover (11) and said arm (13) to cause pivoting of said arm (13) relative to said prime mover (11), a link (14) pivotally attached at one end to the other end of said arm (13) relative to said prime mover (11), a second hydraulic ram (17) extending between said base arm (13) and link (14) so as to pivotally move said link (1 4 ) relative to said base arm (13), a bucket (15) pivotally attached to the other end of said link (14) relative to said base arm (13), a third hydraulic ram (18) extending between said link (14) and said bucket (15) to pivotally move said bucket (15) relative to said link (14), first angle detection means to detect the angle between said base arm (13) and link (14), means to determine the hydraulic pressure in the first hydraulic ram (16) to thereby determine the force applied to said base arm (13) by said first hydraulic ram (16), and means to calculate the weight of the contents in said bucket (15) by receiving information from said first detection means and the means to detect the pressure in said_first hydraulic ram (16).
Claim 3
Dependent Claim
243 words
A combination to determine the payload of a bucket of an articulated arm (10), said combination comprising a base arm (13) to be pivotally attached at one end to a prime mover (11), a first ram (16) extending between said prime mover (11) and base arm (13) to cause pivoting movement of said base arm (13) relative to said prime mover (11), a link (14) pivotally attached at one end to the other end of said base arm (13) relative to said prime mover (11), a second hydraulic ram (17) extending between said link (14) and said base arm (13) to cause pivoting of said link (14) relative to said base arm (13), a bucket (15) to receive powder or particulate matter, said bucket (15) being pivotally attached to the other end of said link (14) relative to said base arm (13), a third hydraulic ram (18) extending between said link (1 4 ) and bucket (15) to cause pivoting of said bucket (15) relative to said link (14), pressure detection means to detect the pressure in said first hydraulic ram (16), and means to detect the rate of change of the angle of said base arm (13) relative to said prime mover (11), and means to calculate the weight of the contents within said bucket (15), given a predetermined position of the bucket (15) relative to said prime mover (11), from the rate of change of angle of said base arm (13).
Claim 4
Dependent Claim
243 words
A combination to determine the payload of a bucket of an articulated arm (10), said combination comprising a base arm (13) to be pivotally attached at one end to a prime mover (11), a first ram (16) extending between said prime mover (11) and base arm (13) to cause pivoting movement of said base arm (13) relative to said prime mover (11), a link (14) pivotally attached at one end to the other end of said base arm (13) relative to said prime mover (11), a second hydraulic ram (17) extending between said link (14) and said base arm (13) to cause pivoting of said link (14) relative to said base arm (13), a bucket (15) to receive powder or particulate matter, said bucket (15) being pivotally attached to the other end of said link (14) relative to said base arm (13), a third hydraulic ram (18) extending between said link (1 4 ) and bucket (15) to cause pivoting of said bucket (15) relative to said link (14), pressure detection means to detect the pressure in said first hydraulic ram (16), and means to detect the rate of change of the angle of said base arm (13) relative to said prime mover (11), and means to calculate the weight of the contents within said bucket (15), given a predetermined position of the bucket (15) relative to said prime mover (11), from the rate of change of angle of said base arm (13).
