Abstract

A manure storage pit pump for attachment to a tractor having a power output shaft and a hitch means for loading manure into a liquid manure transfer tank mounted on a vehicle such as a spreader vehicle or a truck, or for agitating manure in a storage pit. The pump includes a support frame for detachable engagement with the hitch means, and an elongated main frame having one end operatively supported by the support frame. An elongated drive shaft is rotatably carried on the main frame and it is operatively connected to an impeller means which is carried on the main frame. The drive shaft is operatively connected to the usual tractor power output shaft for rotating the drive shaft. An auger means is operatively attached to the drive shaft for moving manure from the manure storage pit into the impeller means. A transfer pipe means is operatively connected to the impeller means for receiving manure from the impeller means and selectively conveying the manure either to the tank on the spreader vehicle or truck, or back into the storage pit for agitating the manure in the storage pit.

Claims

1. In a manure storage pit pump for attachment to a tractoR having a power output shaft and a hitch means, the combination comprising:

a. a support frame pivotally attached to said hitch means;

b. an elongated main frame having one end operatively supported by said support frame;

c. an elongated drive shaft rotatably supported on said main frame;

d. means operatively connecting one end of said drive shaft to said tractor power output shaft for rotating said drive shaft;

e. an impeller means carried on said main frame and being operable by said drive shaft;

f. an auger means operatively attached to the end of said drive shaft for moving manure from a manure storage pit into said impeller means;

g. pipe means being operatively connected to said impeller means for receiving manure from said impeller means;

h. said means operatively connecting one end of said drive shaft to said tractor power output shaft comprising a universal joint means;

i. said impeller means including, 1. a housing carried on said main frame;

2. an impeller operatively mounted on said drive shaft and disposed within said housing for receiving manure and forcing the manure into a discharge port means formed in said housing; and

, 3. said pipe means being operatively connected to said discharge port means in said housing;

j. said discharge port means in said impeller housing including a first outlet port and a second outlet port;

k. said pipe means including a transfer pipe operatively connected to said first outlet port for conveying manure from the impeller housing to a manure transfer vehicle;

l. said pipe means including a rotatably mounted spout operatively connected to said second outlet port for discharging manure from said impeller housing back into the manure storage pit;

m. said discharge port means including a pivotally mounted selector valve for selective opening and closing of said first and second outlet ports; and

, n. the other end of said elongated main frame being unsupported and freely movable up and down for moving the auger means into the manure in a manure storage pit.

2. A manure storage pit pump as defined in claim 1, wherein:

a. said selector valve is provided with means for pivoting the selector valve between one position to close said first outlet port and open said second outlet port, and another position to open said first outlet port and close said second outlet port.

3. A manure storage pit pump as defined in claim 1, wherein:

a. said rotatably mounted spout is provided with means for rotating said spout.

4. A manure storage pump as defined in claim 1, wherein:

a. said auger means comprises at least one auger for moving manure into said impeller housing.

5. A manure storage pit pump as defined in claim 1, wherein:

a. said auger means comprises a plurality of augers for moving manure into said impeller housing.

6. A manure storage pit pump as defined in claim 1, wherein:

a. said main frame has one end fixed to said support frame, and said support frame is pivotally attached to said hitch means.

7. A manure storage pit pump as defined in claim 1, wherein:

a. said main frame has one end pivotally mounted on said support frame;

b. said support frame is pivotally attached to said hitch means; and

, c. a power operated apparatus is operatively mounted on said support frame and engages said main frame for pivoting the main frame relative to said support frame.

8. A manure storage pit pump as defined in claim 7, wherein:

a. said power operated apparatus comprises a fluid operated cylinder having a head end and a cylinder rod end, and having the head end thereof pivotally attached to said support frame, and the cylinder rod thereof pivotally attached to said main frame.
