Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
72 words
A combine harvester comprising a rotary threshing and separating mechanism (9), and grain loss sensor means (136) operable to produce a signal indicative of the grainlosses occurring rearwardly of the separating mechanism (9), characterized in that the grainloss sensor means (13) are mounted to one side of the threshing and separating mechanism (9) such that separated grain is propelled on to the sensor means (136) by the threshing and separating mechanism (9).
Claim 2
Dependent Claim
72 words
A combine harvester comprising a rotary threshing and separating mechanism (9), and grain loss sensor means (136) operable to produce a signal indicative of the grainlosses occurring rearwardly of the separating mechanism (9), characterized in that the grainloss sensor means (13) are mounted to one side of the threshing and separating mechanism (9) such that separated grain is propelled on to the sensor means (136) by the threshing and separating mechanism (9).
Claim 3
Dependent Claim
34 words
A combine harvester according to claim 1, characterized in that the grain loss sensor means (136) comprise one or more sensors and in that the or each grain loss sensor is mounted generally vertically.
Claim 4
Dependent Claim
36 words
A combine harvester according to claim 1 or 2, characterized in that the or each grain loss sensor (136) is made part of a wall (133) of a housing for the threshing and separating mechanism (9).
Claim 5
Dependent Claim
25 words
A combine harvester according to claim 3, characterized in that the wall (133) of the housing for the-threshing and separating mechanism (9) extends generally vertically.
Claim 6
Dependent Claim
59 words
A combine harvester according to any of claims 2 to 4, characterized in that the or each grain loss sensor (136) is mounted on the exterior of said wall (133) of the housing for the threshing and separating mechanism (9), with the or each sensor (136) being exposed to the impacting grain through an aperture in that wall (133).
Claim 7
Dependent Claim
49 words
A combine harvester according to any of the preceding claims, characterized in that the threshing and separating mechanism (9) has a separating mechanism and in that the or each grain loss sensor (136) is counted to one side of the separating mechanism adjacent a discharge end of the latter.
Claim 8
Dependent Claim
70 words
A combine harvester according to claim 6, characterized in that the threshing and separating mechanism (9) further comprises a threshing mechanism (17) separate from the separating mechanism, in that at least one end of the latter extends past the associated end of the threshing mechanism (17), and in that at least one grain loss sensor (136) is mounted to one side of said one end of the separating mechanism (9).
Claim 9
Dependent Claim
65 words
A combine harvester according to claim 7, characterized in that both ends of the separating mechanism (9) extend past the respective ends of the threshing mechanism (17) with crop material being discharged from each end of the separating mechanism (9), and in that at least one grain loss sensor (136) is mounted to one side of the separating mechanism (9),: adjacent each discharge end thereof.
Claim 10
Dependent Claim
68 words
A combine harvester according to any of the preceding claims, characterized in that the or each sensor (136) comprises a non-metallic plate (9) on which is mounted at least one piezoelectric crystal (141), the plate (139) being mounted in the mouth of a dished housing (137) filled with a shock resistant material, whereby the sensor (136) is vibrationally isolated from the housing (137) and hence from the machine.
