Abstract
Abstract A manure spreader, in combination with a tractor, consisting of a tank with a horizontal axis aligned with the normal movement of the tractor which tows it. A comminuter is provided between the tractor and the tank which has an inlet from the tank near its bottom and four rotating flail blades curved forwardly near their ends. A pair of opposite outlets lead to hoses which selectively may be connected to ejectors on a cultivator carried by the tractor's three-point hitch or the hoses may be connected to pipes leading to spray-type spreaders disposed near the tractor. In one embodiment, the inlet to the comminuter is tangential to a circumference circumscribed by ends of the flail blades with a knife disposed in a lower portion of same. In another embodiment, the entrance into the comminuter is about one-third the distance up from the bottom of its casing. A pump which may either pull a vacuum or place a pressure on the tank may be mounted on the tank's frame. Alternatively, the tank may be filled by gravity through a closeable opening on its top. In the embodiment wherein the tank pressure is controlled by a pump, the opening is on the tank's bottom and the outlet duct therefrom extends from a cylindrical flange for this closeable opening in the tank's bottom.

An implement for spreading liquid and semi-liquid materials including a tank for containing said material, a material delivering mechanism which comprises a substantially cylindrical casing, an inlet port in fluid passage communication with the interior of said tank, a material reducing mechanism mounted to rotate in said casing about a horizontal axis concentric with said casing, said material reducing mechanism including a plurality of blades adapted to rotate about said axis for moving material into and from said casing, each said blade including an outwardly extending cutting part which rotates closely adjacent the interior of said casing for cutting solid materials received therein, a plurality of outlet ports in said casing and a delivery duct connected to said casing at each said outlet port whereby each said delivery duct extends substantially perpendicularly away from said casing at least in the immediate vicinity thereof whereby material moving from said casing into said duct abruptly changes direction by an angle of about 90°, the passageway of each said delivery duct having an equal cross-sectional area whereby the rate of material flowing through each delivery duct as a result of the rotation of such blades is substantially equal.
Claim 91
Dependent Claim
128 words
An implement according to claim 81 wherein said inlet port connects with a further duct which is substantially larger in cross-section than each of said first-mentioned ducts, the longitudinal axis of said further duct being substantially tangential to said casing, the extreme end of said further duct adjacent said casing being closed by a projection extending substantially at right angles outwardly of said casing and a cutting blade member included in said projection having a cutting edge closely adjacent the circumference described by the rotation of the outer end of each cutting part whereby solids in said material moving through said further duct agaist said projection are reduced by the cooperative cutting action of said cutting edge and each said cutting part during the rotation of the latter.
Claim 92
Dependent Claim
56 words
An implement according to claim 81, wherein said inlet port connects directly to an opening in the bottom of said tank, said inlet port being in a wall of said casing which is perpendicular to said horizontal axis and which is at a location below said horizontal axis and above the lowest aspect of said casing.
Claim 93
Dependent Claim
31 words
An implement according to claim 83, wherein each said cutting part is wider than the remaining portion of said blade whereby said remaining portion is spaced outwardly from said inlet port.
