Abstract

A liquid manure spreader includes a hollow housing chamber having a generally cylindrical sidewall, a chamber bottom provided with a pattern of obround outlet openings, an array of outlet tubes connected to receive material through the obround openings and an inlet cover on the housing. The slurry distributor also includes a rotating hollow expeller member to secure and distribute slurry to the obround outlets having a central rotational axis and a plurality of outlet chambers which have cutter blades attached. A hydraulic motor is connected to rotate the expeller in the housing chamber. A cutter plate is mounted to the chamber bottom and has a pattern of obround openings matching that in the chamber bottom that cooperates with the cutter blade to prevent clogging of the outlet openings.

Claims

1. A liquid manure slurry distributor

(a) a hollow housing chamber having a generally cylindrical sidewall, a chamber bottom provided with a pattern of obround openings, an array of outlet tubes connected to receive material through said obround or elongated openings and an inlet cover on said housing;

(b) a hollow expeller member having a central rotational axis mounted for rotation in said chamber and having cutter blades attached thereto; and

(c) a motor connected to rotate said expeller in said housing chamber.

2. A distributor as in claim 1 further comprising a cutter plate mounted above said chamber bottom and having a pattern of obround or elongated openings matching that in said chamber bottom.

3. A distributor as in claim 1 wherein said motor is a hydraulic motor.

4. A distributor as in claim 2 wherein said motor is a hydraulic motor.

5. A distributor as in claim 1 further comprising spaced reusable clamping devices for resealably closing said inlet cover.

6. A distributor as in claim 1 wherein said lid is hinged to said housing chamber.

7. A distributor as in claim 6 further comprising spaced reusable clamping devices for resealably closing said inlet cover.

8. A distributor as in claim 1 wherein said obround openings are uniform in size and distributed about the chamber bottom in a regular pattern.

9. A distributor as in claim 1 wherein said expeller has a central inlet and regular pattern of four outlet openings.

10. A distributor as in claim 1 wherein said inlet cover has a central opening to receive an inlet pipe.

11. A distributor as in claim 1 wherein said outlet tubes are adapted to transfer liquid manure slurry to hoses connected thereto.

12. A distributor as in claim 2 wherein said cutter blades and said cutter plates are attached using removable fasteners.

13. A method of providing equal distribution of a liquid manure slurry through an array of supply hoses comprising:

(a) providing a hollow housing chamber having a generally cylindrical sidewall, a chamber bottom provided with a pattern of obround openings, an array of outlet tubes connected to receive material through said obround openings and an inlet cover on said housing; and

a motor-operated rotating hollow expeller member having a central rotational axis mounted for rotation in said chamber and having material distributing lobes and cutter blades attached thereto;

(b) rotating said hollow expeller while supplying liquid manure slurry through said inlet cover to said expeller to distribute said slurry evenly among said obround openings to said outlet tubes.

14. A method as in claim 13 further comprising using the cutter blades in conjunction with a cutter plate mounted above and matching said bottom obround openings to prevent clogging of said obround openings.
