Abstract
A mixer having an open top mixing box accommodating a pair of lower augers and a pair of upper paddle conveyors drivably connected to the augers. A power box pivotally mounted on one end of the mixing box is drivably connected to the augers with releasable drive connections. The power box is a motor driven power transmission assembly that can be disconnected from the augers and removed from the mixing box. A movable door associated with the bottom of the mixing box is used to selectively open and close a discharge opening allowing mixed and blended material to be discharged into a conveyor.
Claims67
An apparatus for mixing material comprising:
- first box means having a chamber for accommodating material, second means located in said chamber for mixing (the) material located in the chamber, means movably mounting the second means on the box means, power means for moving the second means in a manner to mix material in the chamber, releasable drive means drivably connecting the power means with the second means, and means mounting the power means on the (first) box means for movement of the power means to a first position wherein the releasable means drivably connects the power means with the second means and for movement from the first position to a second position wherein the releasable means separates the power means from the second means to disconnect the drive between the power means and second means.
An apparatus for mixing material comprising:
- first means having a chamber for accommodating material, second means located in said chamber for mixing the material in the chamber, power means for moving the second means in a manner to mix material in the chamber, means mounting the power means on the first means for selective movement of the power means to a first position and from the first position to a second position, and releasable means drivably connecting the power means with the second means when the power means is in its first position and separating the power means from the second means when the power means is in its second position, said second means including a plurality of driven shafts, and said power means including a plurality of drive shafts equal in number to the driven shafts, said releasable means drivably connecting the power means with the movable means comprising separate releasable drive couplings, each coupling having a first member secured to a driven shaft and a second member secured to a drive shaft, said first and second members having engaging means operable to transmit power from the second member to the first member when the power means is in its first position.
An apparatus for mixing material comprising:
- first means having a chamber for accommodating material, second means located in said chamber for mixing the material in the chamber, power means for moving the second means in a manner to mix material in the chamber, means mounting the power means on the first means for selective movement of the power means to a first position and from the first position to a second position, and releasable means drivably connecting the power means with the second means when the power means is in its first position and separating the power means from the second means when the power means is in its second position, said first means comprising a box having said chamber, an open top, means on said box for allowing material to move out of said chamber, said second means comprising a pair of augers located along a lower section of said chamber, and a pair of conveyor means located in said chamber above said augers, means rotatably mounting one end of each auger on said box, means rotatably mounting each of said conveyor means on said housing, said releasable means drivably connecting the power means to the other end of each auger, and power transmitting means connecting the augers to the conveyor means when the power means is in its first position.
A material mixing apparatus comprising:
- box means having a chamber, means on said box means allowing material to move from said chamber, auger means located in said chamber for mixing material in said chamber, power means for rotating said auger means, means mounting the power means on the box means for movement to a first position and a second position, and releasable drive coupling means connecting the power means to the auger means when the power means is in its first position and separating the power means from the auger means when the power means is in its second position.
A material mixing apparatus comprising:
- box means having a chamber for accommodating material, said box means having a bottom wall, side walls joined to and extended upwardly from the bottom wall, a first end wall attached to the bottom wall and side walls to close one end of said box means, a second end wall attached to the bottom wall and side walls to close the other end of said box means, a first auger and a second auger longitudinally located in said chamber adjacent the bottom wall, means rotatably mounting said augers on said box means, power means drivably connected to said augers to concurrently rotate said augers, means movably mounting the power means on the box means for movement to first and second positions, said first auger having a first helical flight having a turn for moving material away from the first end wall to a first area located adjacent the second end wall and a second helical flight having a turn opposite the turn of the first helical flight for moving material away from the second end wall into said first area, said first area being located between adjacent ends of the first and second helical flights whereby on rotation of the first auger material is mixed and moved upward in said first area, said second auger for moving material away from the first end wall into said second area, said second area being located between adjacent ends of the first and second helical flights of the seond auger whereby on rotation of the second auger material is mixed and moved upward in said second area, first conveyor means rotatably mounted on said first and second end walls above said first auger operable to move material from the first area to the first end wall, second conveyor means rotatably mounted on said first and second end walls above said second auger operable to move material from the second area to the second end wall, means drivably connecting the first and second conveyor means to the first and second augers whereby the power means drives said conveyor means, and releasable drive coupling means drivably connecting the power means to the first and second augers when the power means is in its first position and disconnecting the power means from the first and second augers when the power means is in its second position.
An apparatus for mixing material comprising:
- first means having a chamber for accommodating material, said first means having a first wall and a second wall, said first wall and second wall defining opposite portions of the chamber, second means having at least one rotatable member extended between said first and second walls located in the chamber for mixing the material in said chamber, said rotatable member having a first end and a second end, means rotatably mounting the first end of said rotatable member on said first end wall, said second wall having an opening of a size to allow the rotatable member to be removed from the chamber through said opening, drive means releasably connected to the rotatable member for rotating said rotatable member, releasable drive coupling means connecting the drive means to the second and of said rotatable member, said drive means and drive coupling means having means to support the second end of said rotatable member, and means mounting the drive means on the first means for selected movement of the drive means to a first position wherein the releasable drive coupling means drivably connects the drive means to the rotatable member and to a second position wherein the releasable drive coupling means separates the drive means from the rotatable member to disconnect the drive between the drive means and the rotatable member.
