Abstract
A manure spreader device and method of distributing any of a variety of manure materials having varying consistencies are provided. The device and method embody a concept in which a plurality of elongated augers that are longitudinally positioned within a translatable bin deliver manure material to an outfeed location for translation of the manure material to a beater assembly which distributes the manure material onto a field or the like. A slippage characteristic is exhibited at the outfeed location whereby, when manure material within the outfeed location exceeds the expelling rate capacity of the beater assembly, slippage occurs between the manure material and rotating blades at the outfeed location so as to avoid overloading of the beater assembly by the particular manure material being spread.
Claims21
A manure spreader for distributing any of a variety of manure materials having varying consistencies, comprising:
- a bin mounted onto a frame having ground engaging wheels, said bin having a side wall and an opening therethrough;
- at least two auger assemblies longitudinally mounted with the bin in side-by-side relationship, said auger assemblies partially define outfeed means generally adjacent to said opening of the sidewall, and said auger assemblies include means for feeding manure materials in a feed direction longitudinally generally along the auger assemblies;
- a beater assembly positioned generally at said sidewall opening, said beater assembly having beater paddles for receiving manure materials from said outfeed means and for distributing such manure material onto a field, said beater assembly having a limited expelling rate capacity for distributing the manure material, said beater assembly having at least one generally vertical shaft onto which said beater paddles are mounted;
- drive means for rotating said auger assemblies and for rotating said shaft of the beater assembly;
- each auger assembly includes at least two different flight profiles, one such profile including members for moving the manure materials toward and into said outfeed means, and the other such profile including outfeed blade members partially defining the outfeed means, said outfeed blade members being positioned to receive the manure material from said one such profile and for delivering the thus received manure material to said beater assembly;
- and
- said outfeed means is further defined by a lower wall of the bin, said outfeed blade members move the manure materials generally between said lower wall and said other such profiles of the auger assemblies, and said blade members are mounted to exhibit a slippage characteristic with respect to the manure material within the outfeed means whereby manure material moved into the beater assembly by the outfeed means is retarded when manure material fed to the outfeed means exceeds the expelling rate capacity of the beater assembly.
The manure spreader in accordance with claim i, wherein said beater paddles include teeth at a radially extending edge thereof, and said beater paddles are mounted in a generally spiral manner onto the generally vertical shaft.
A method for distributing any variety of manure materials having varying consistencies, comprising the steps of:
- depositing a supply of manure material into a translatable bin having a wide-mouth configuration and a sidewall with an opening therethrough;
- augering said manure material within the bin longitudinally along at least two side-by-side auger assemblies therewithin, said augering step including moving said manure material in a feed direction flow by rotating action imparted thereto by the auger assemblies;
- said augering step including moving said manure material to an outfeed location of the bin that is deeper than the location of the auger assemblies within the bin;
- outfeeding the manure material within the outfeed location, said outfeeding step moving the manure material to a beater assembly in the vicinity of the sidewall opening, the beater assembly having a limited expelling rate capacity;
- receiving the manure from said outfeeding step by the beater assembly at a location generally external of the opening in the sidewall, including expelling manure material out of the bin in a spray pattern;
- and
- said outfeeding step includes slipping between said manure material and blades within the outfeeding location whereby manure material moved into the beater assembly during the outfeeding step is retarded when manure material handled during the outfeeding step exceeds the expelling rate capacity of the beater assembly.
