When the grains with the straws and the glumes flow on the step plate 2-2, the guide plates 2-30 guide the grains and enable the grains to roll, and the guide plates 2-30 roll the grains to enable the straws and the glumes mixed in the grains to move to the upper surfaces of the grains while enabling the grains to be uniformly heated.
When the grains move to the filter plates 2-3, the filter plates 2-3 filter the straws to enable the straws to be retained on the filter plates 2-3, meanwhile, the straws move in a space formed by the three groups of filter plates 2-3 and enter the discharge space through air blown out by the flow dividing pipes 2-29, and when the grains flow through the filter plates 2-3 and pass through the steps of the step plates 2-2, the chaffs in the grains are blown by the air outlet pipes 2-21 to enable the chaffs to be separated from the grains and enter the discharge space through the feed inlet.
The cleaning fan 3-1 transmits air to the lower part of the vibrating filter plate 3-3 through the blast pipe 3-11, when the air passes through the power wind wheel 3-24 in the blast pipe 3-11, the power wind wheel 3-24 drives the transmission shaft 3-21 to rotate under the driving of the air flow, the transmission shaft 3-21 transmits the rotating power to the following shaft 3-25 through the worm 3-23 and the turbine 3-26, the following shaft 3-25 drives the rotating wheel 3-28 to rotate through the rotating power, the rotating wheel 3-28 drives the deflection wheel 3-29 to rotate, the deflection wheel 3-29 lifts one end of the vibrating filter plate 3-3 when rotating, so that one end of the vibrating filter plate 3-3 rises, and when the deflection wheel 3-29 rotates by 90 degrees under the driving of the rotating wheel 3-28, the deflection wheels 3-29 are separated from the vibration filter plates 3-3 under the action of self gravity, so that the vibration filter plates 3-3 lose supporting force and move downwards under the action of self gravity, and collide with the support plates to enable the vibration filter plates 3-3 to generate vibration, the vibration filter plates 3-3 perform secondary filtration on grains through vibration, short straws and glumes in the grains move to the upper surfaces of the grains, and the short straws and the glumes move towards the direction of the discharge space and enter the discharge space under the action of the driving of air flow above the vibration filter plates 3-3 and the inclined arrangement of the vibration filter plates 3-3.
After air flows below the vibrating filter plate 3-3 from the air supply pipe 3-11, the air flow separates fine grains and damaged grains from grains flowing down the vibrating filter plate 3-3, so that the grains are separated at different floating speeds and leave the cleaning device through the fine grain discharge hopper 1-2 and the damaged grain discharge hopper 1-3.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
