Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in the cleaning screen in fig. 1, the cleaning screen is provided with a vibrating screen body 1, a flow guide mechanism 2 is positioned above the vibrating screen body 1, and the screened material moves on the vibrating screen body 1 from front to back; as shown in fig. 2-3, the steering mechanism 2 includes a plurality of steering wheels 21 arranged in an array in the left-right direction; the guide wheel 21 comprises a wheel core 21a and guide rods 21b fixed on the periphery of the wheel core 21a in a circumferential array; the guide wheel 21 actively rotates around the first central axis a, and the first central axis a rotates around the second central axis b which is intersected with the first central axis a and is not mutually perpendicular to the first central axis a, so that the guide rod 21b performs space compound motion, the guide rod 21b can interfere and guide the motion of materials on the vibrating screen body 1, assist the backward motion of the materials, prevent the high-humidity materials from depositing on the screen surface, increase the collision among the materials, reduce the wrapping and clamping of seeds, angular shells and other sundries, improve the loose degree and uniformity of the materials, reduce the screening pressure and improve the probability of the seeds to pass through the screen.
In particular, as shown in fig. 2-3, the diversion mechanism 2 further includes a drum 22 and a drive joint 23 mounted within the drum 22; the guide wheel 21 is rotatably mounted on the driving joint 23, a central axis of the guide wheel relative to the driving joint 23 is the first central axis a, and the driving joint 23 rotates around the second central axis b; the second central axis b extends in the left-right direction; the wheel core 21a is placed in the drum 22; the drum 22 is provided with a strip-shaped hole 22a provided corresponding to each of the guide rods 21b, the strip-shaped hole 22a extending in the axial direction of the drum 22; each of the guide rods 21b passes through the corresponding bar-shaped hole 22a and extends out of the drum 22; the drum 22 and the driving joint 23 are respectively driven to rotate, and are respectively driven to run by a first driving wheel 25 and a second driving wheel 26. And the rotational speed and/or rotational direction of both the drum 22 and the drive joint 23 are different.
For convenience of description, as shown in fig. 4, a coordinate system O-XYZ is set up for the flow guiding mechanism 2, in which the X axis coincides with the second central axis b, that is, is parallel to the left-right direction; the Z axis extends in the vertical direction; the Y axis is parallel to the front-rear direction, and the origin O is the intersection point of the first central axis a and the second central axis b. Both the driving joint 23 and the drum 22 rotate around the X axis, and since the first central axis a is inclined relative to the second central axis b, when the driving joint 23 actively rotates, the first central axis a can rotate around the X axis (i.e., the second central axis b), and the surface swept by the first central axis a is a conical surface with the origin O as the vertex (as shown in fig. 4); since the drum 22 actively rotates and the guide rod 21b passes through the bar-shaped hole 22a to make most of the entity outside the drum 22, the guide rod 21b acts on the guide rod 21b through the wall of the bar-shaped hole 22a to push the guide wheel 21 to rotate relative to the driving joint 23 when the drum 22 rotates, so that the guide rod 21b can perform space compound motion.
Because the guide rod 21b performs space compound movement, the range of materials which can act on the guide rod is wider, and the layout density of the guide wheels 21 in the left-right direction can be reduced. Because the rotation speeds and/or the rotation directions of the rotating drum 22 and the driving joint 23 are different, the frequency of the space compound motion of the flow guide rod 21b can be greatly increased.
As shown in fig. 5, the driving joint 23 has a chute 23a arranged obliquely, and as shown in fig. 6, a roller 24 is installed in the inducer 21; the roller 24 is placed in the chute 23a and moves along the chute 23 a. With the above structure, the inducer 21 can move smoothly with respect to the drive joint 23.
The guide rod 21b has two rod sections, and an included angle between the two rod sections is an obtuse angle, wherein the rod section connecting the wheel core 21a extends along the radial direction of the wheel core 21 a. When the guide wheel 21 rotates, the turning part between the two rod sections on the guide rod 21b faces along the movement direction of the guide rod 21b, and in addition, the guide rod 21b has elasticity, so that when materials on the screen surface are piled up higher or encounter hard foreign matters, the guide rod 21b can be bent and deformed along the turning part, and the guide rod 21b has self-adaptive deformation capability, and can also avoid the collision damage of the guide rod 21b to the hard matters.
According to the uniform dispersion flow guiding mechanism for the screening sieve surface, through the flow guiding wheel with the first central shaft capable of swinging back and forth, the flow guiding rod of the flow guiding wheel performs space compound motion, the backward motion of materials is assisted, the deposition of high-humidity materials on the sieve surface is prevented, the collision among the materials is increased, the wrapping and clamping of seeds, angle shells and other sundries are reduced, the loosening degree and uniformity of the materials are improved, the screening pressure is reduced, and the probability of the seeds to pass through the sieve is improved. Because the guide rod performs space compound movement, the guide rod can interfere materials in a wider range, and the layout density of the guide wheel can be reduced.
The foregoing is only a preferred embodiment of the invention, it being noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
