Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following examples.
A tea roller sorting device comprises a supporting table 1, wherein a sorting cylinder, a power mechanism and a blanking mechanism are respectively arranged on the supporting table.
The sorting cylinder is a horizontally arranged cylindrical shell and is rotatably positioned on the support table around a horizontal axis. As shown in fig. 2, the left end of the sorting cylinder is an inlet and the right end is an outlet, the inlet is provided with a feed hopper (omitted in the figure), and the outlet is provided with a discharge hopper (omitted in the figure). The separation cylinder is formed by axially connecting a plurality of sections, the cylinder wall of each section is a flexible screening net 21, a plurality of spiral plates 22 are arranged on the inner circumferential surface of the cylinder wall and are uniformly distributed along the circumferential direction, a certain included angle (preferably 20-45 degrees) is formed between the length direction of each spiral plate and the axis of each section, a plurality of connecting sleeves 23 parallel to the axis of each section are arranged on the outer circumferential surface of the cylinder wall, a plurality of connecting rods 24 are inserted into the connecting sleeves one by one, and two connecting rings are respectively fixed at the end parts of the connecting rods. The connecting rod struts the flexible screening net to keep the flexible screening net in a cylindrical shape. The flexible screening net adopted by the segmented cylinder wall and the connecting sleeve arranged outside the cylinder wall are woven by flexible ropes (preferably ropes woven by plant fibers).
The number of the segments is generally 3-5, which is determined according to the actual situation. As shown in fig. 2, the sorting cylinder includes a first section a, a second section B, a third section C, and a fourth section D, which are sequentially arranged along the moving direction of the tea leaves (the direction from left to right in fig. 2). The two connection rings of the first segment are respectively a first connection ring 31 and a second connection ring 32, the two connection rings of the second segment are respectively a second connection ring 32 and a third connection ring 33, the two connection rings of the third segment are respectively a third connection ring 33 and a fourth connection ring 34, and the two connection rings of the fourth segment are respectively a fourth connection ring 34 and a fifth connection ring 35. The aperture of the flexible screening net of the second section is larger than that of the flexible screening net of the first section, the aperture of the flexible screening net of the third section is larger than that of the flexible screening net of the second section, and the aperture of the flexible screening net of the fourth section is larger than that of the flexible screening net of the third section (in two adjacent sections, the aperture of the screening net of the right section is larger than that of the screening net of the left section).
