Abstract
The invention relates to a grain sweep (1) for use on a floor comprising at least a first drive means (2), an elongated frame (3) comprising a rotatably arranged inner end (4) and an outer end (5), a drive wheel (6) adapted to rotate the elongated frame (3) around said inner end (4), and a grain moving means (7) adapted to move grain. The grain sweep (1) further comprises at least one resilient member (8) arranged at either said inner (4) or outer end (5) of said elongated frame (3), wherein the resilient member (8) allows the elongated frame (3) to move from said upper position towards a lower position when pressure is applied upon the elongated frame (3), and wherein the resilient member (8) allows the elongated frame (3) to move back towards said upper position when the pressure is removed.

A grain sweep for use on a floor comprising:
- at least a first motor,
- an elongated frame comprising a rotatably arranged inner end and an outer end,
- a drive wheel adapted to rotate the elongated frame around said inner end,
- a conveyor adapted to move grain,
- at least one resilient member arranged at either said inner or outer end of said elongated frame,
- wherein the resilient member allows the elongated frame to move from an upper position towards a lower position when pressure is applied upon the elongated frame,
- wherein the resilient member allows the elongated frame to move back towards said upper position when the pressure is removed,
- wherein a first end of said resilient member is directly or indirectly rotatably connected to either the inner or the outer end of the elongated frame and a second end of the resilient member is rotatably connected to a holding member, and wherein the resilient member allow the elongated frame to move with respect to the holding member, and
- wherein the elongated frame moves in relation to said holding member when pressure is applied upon the elongated frame such that said holding member essentially remains in its vertical position when the elongated frame moves from its upper position.
A grain sweep for use on a floor, comprising:
- at least a first motor,
- an elongated frame comprising a rotatably arranged inner end and an outer end,
- a drive wheel adapted to rotate the elongated frame around said inner end,
- a conveyor adapted to move grain,
- at least one resilient member arranged at either said inner or outer end of said elongated frame, and
- a bracket, wherein said bracket is rotatably engaged to an axis of said holding member,
- wherein a second end of said resilient member is rotatably engaged to said bracket by means of a second pivot joint
- wherein the resilient member allows the elongated frame to move from an upper position towards a lower position when pressure is applied upon the elongated frame,
- wherein the resilient member allows the elongated frame to move back towards said upper position when the pressure is removed, and
- wherein said bracket is further engaged to said housing or elongated frame.
A grain sweep for use on a floor, comprising:
- at least a first motor,
- an elongated frame comprising a rotatably arranged inner end and an outer end,
- a drive wheel adapted to rotate the elongated frame around said inner end,
- a conveyor adapted to move grain,
- at least one resilient member arranged at either said inner or outer end of said elongated frame,
- wherein the resilient member allows the elongated frame to move from an upper position towards a lower position when pressure is applied upon the elongated frame,
- wherein the resilient member allows the elongated frame to move back towards said upper position when the pressure is removed,
- wherein a housing is arranged to cover said drive wheel and said resilient member, and wherein said outer end of said elongated frame is connected to the housing, and wherein the first end of the resilient member is connected to the elongated frame via the housing, and
- wherein the housing is arranged to rotate around from the axis of the drive wheel when pressure is applied upon the elongated frame such that the housing tilts forward and downwards towards the floor.
