Abstract
A digger for facilitating the application of a material to a mushroom bed includes a feed system wherein a metering shaft is provided in the compartment or hopper for the material. The metering shaft contains sets of supply pockets which receives the material to be conveyed to distribution heads. The digger also includes a digging shaft connected to a drive shaft by improved structure.

In a digger for facilitating application of a material to a mushroom bed wherein said digger includes a compartment for containing a supply of the material to be applied, a longitudinally mounted digging shaft, a plurality of digging tines extending generally radially outwardly from said digging shaft, a drive assembly connected to said digging shaft for rotating said digging shaft to cause said tines to dig into a mushroom bed when said digger is placed on a mushroom bed, conveying structure for conveying the material from said compartment and directing the material toward the mushroom bed generally at the location of said tines digging into the mushroom bed simultaneously with the digging of said tines, the improvement being in that said conveying structure includes a plurality of distributor heads located generally at said tines, a power driven rotatable metering shaft having a plurality of sets of supply pockets for collecting material from said compartment, each of said sets of supply pockets being in periodic communication with a separate outlet hose for depositing the material into a respective said outlet hose during rotation of said metering shaft, each of said outlet hoses leading to a respective one of said distributor heads for supplying the material to said distributor heads, said conveying structure includes a plurality of sets of inlet and outlet hoses, each of said sets of inlet and outlet hoses includes a separate inlet hose for supplying conveying fluid to a respective one of said outlet hoses, said material being deposited into a manifold which interconnects each set of said sets of inlet and outlet hoses, said inlet hose is of smaller diameter than said outlet hose, each of said sets of supply pockets comprises a plurality of circumferentially aligned equally spaced pockets, said compartment having a tapered bottom, said metering shaft being mounted in said tapered bottom of said compartment, said manifold includes a plurality of receiving pockets corresponding in number to the number of sets of said supply pockets and the number of said distributor heads, each pocket of said set of said circumferentially aligned pockets is longitudinally aligned with other supply pockets of said other sets of circumferentially aligned pockets, and said sets of circumferentially aligned pockets communicate with adjacent sets of circumferentially aligned pockets by breaker bridges formed as grooves in an outer surface of said metering shaft.
In a digger for facilitating application of a material to a mushroom bed wherein said digger includes a compartment for containing a supply of the material to be applied, a longitudinally mounted digging shaft, a plurality of digging tines extending generally radially outwardly from said digging shaft, a drive assembly connected to said digging shaft for rotating said digging shaft to cause said tines to dig into said mushroom bed when said digger is placed on said mushroom bed, with conveying structure for conveying the material from said compartment and directing the material toward said mushroom bed generally at a location of said tines digging into said mushroom bed simultaneously with the digging of said tines, the improvement being in that said digging shaft being hollow, a drive shaft connected to said drive assembly, said drive shaft terminating in a stub portion telescoped into said hollow digging shaft, said drive shaft including a drive portion operatively connected to and driven by said drive assembly, said drive portion being of larger diameter than said stub portion, and connecting structure connecting said drive shaft to said digging shaft.
In a digger for facilitating application of a material to a mushroom bed wherein said digger includes a compartment for containing a supply of the material to be applied, a longitudinally mounted digging shaft, a plurality of digging tines extending generally radially outwardly from said digging shaft, a drive assembly connected to said digging shaft for rotating said digging shaft to cause said tines to dig into a mushroom bed when said digger is placed on a mushroom bed, conveying structure for conveying the material from said compartment and directing the material toward the mushroom bed generally at the location of said tines digging into the mushroom bed simultaneously with the digging of said tines, the improvement being in that said conveying structure includes a plurality of distributor heads located generally at said tines, a power driven rotatable metering shaft having a plurality of sets of supply pockets for collecting material from said compartment, each of said sets of supply pockets being in periodic communication with a separate outlet hose for depositing the material into a respective said outlet hose during rotation of said metering shaft, each of said outlet hoses leading to a respective one of said distributor heads for supplying the material to said distributor heads, said digging shaft is hollow, a drive shaft is telescoped into said digging shaft, a motor assembly drives said drive shaft, connecting structure connects said drive shaft to said digging shaft for joint movement of said drive shaft and said digging shaft, said drive shaft has a reduced diameter stub portion in said digging shaft, and said drive shaft has an enlarged diameter portion connected to said motor assembly.
In a digger for facilitating application of a material to a mushroom bed wherein said digger includes a compartment for containing a supply of the material to be applied, a longitudinally mounted digging shaft, a plurality of digging tines extending generally radially outwardly from said digging shaft, a drive assembly connected to said digging shaft for rotating said digging shaft to cause said tines to dig into a mushroom bed when said digger is placed on a mushroom bed, conveying structure for conveying the material from said compartment and directing the material toward the mushroom bed generally at the location of said tines digging into the mushroom bed simultaneously with the digging of said tines, the improvement being in that said conveying structure includes a plurality of distributor heads located generally at said tines, a power driven rotatable metering shaft having a plurality of sets of supply pockets for collecting material from said compartment, each of said sets of supply pockets being in periodic communication with a separate outlet hose for depositing the material into a respective said outlet hose during rotation of said metering shaft, each of said outlet hoses leading to a respective one of said distributor heads for supplying the material to said distributor heads, and said sets of supply pockets communicate with adjacent sets of supply pockets by breaker bridges formed as grooves in an outer surface of said metering shaft.
