Abstract

Abstract The blowing, metering and distributing assembly 4 (Figure 2) of a liquid or air flows solids distributor and the extended distribution members are suspended from the chassis 1 by four downwardly converging rigid links 5, each having ball swivel joints 6 at its two ends. Due to the high polar inertia of the suspended assembly, it will not respond to transient yawing, rolling or pitching movements of the chassis but if such movements are sustained, the assembly will re-align to some new rest position. In other embodiments, the number and/or direction of convergence of the suspension links is varied from those shown in Figure 2. The assembly is particularly useful in certain types of agricultural machinery where the operative part of the machine has to be suspended from the body portion of the machine.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 49 words
A suspension assembly characterised in that it comprises a first part of a machine suspended from a second part of the machine by three or more upwardly or downwardly converging rigid links each connected to each of the two parts by a ball joint or other multi-directional mechanical connection.
Claim 2
Dependent Claim 49 words
A suspension assembly characterised in that it comprises a first part of a machine suspended from a second part of the machine by three or more upwardly or downwardly converging rigid links each connected to each of the two parts by a ball joint or other multi-directional mechanical connection.
Claim 3
Dependent Claim 49 words
A suspension assembly as claimed in Claim 1 characterised in that there are four or more said links and the links converge upwardly when viewed in a first vertical plane but converge downwardly when viewed in a second vertical plane lying at right angles to the first vertical plane.
Claim 4
Dependent Claim 18 words
A machine characterised in that it includes a suspension assembly as claimed in Claim 1 or Claim 2.
Claim 5
Dependent Claim 36 words
A solid or liquids distributor characterised in that it incorporates an assembly as claimed in Claim 1 or Claim 2 in which a distribution boom of the distributor comprises or is supported by said first part.
Claim 6
Dependent Claim 26 words
A sprayer, spreader, wick-type applicator, mowing machine, combine harvester, spinning disc spreader or like machine incorporating an assembly as claimed in Claim 1 or Claim 2.
