Detailed Description

As shown in fig. 1, a self-turning black tea withering conveyor includes a scraper chain conveyor body 1, and the scraper chain conveyor body 1 has substantially the same basic structure as a conventional scraper chain conveyor, and includes a housing 4, a scraper chain 6, a chain 10, a sprocket 11, a driving device (a chain conveying mechanism 12, a first motor 13), and the like. The difference lies in that the chain-plate conveyor body 1 is of a horizontal hook structure integrally and comprises a horizontal part 1.1, a lower bending part 1.2, a lifting part 1.3 and an upper bending part 1.4. Therefore, tea leaves are input from the horizontal part 1.1, fall from the upper bending part 1.4 after passing through the lower bending part 1.2 and the lifting part 1.3, return to the horizontal part 1.1, and are turned over by repeating the process. And a plurality of groups of air pipes 16 are arranged at the bottom of the shell 4 of the chain-plate conveyor body 1, and each group of air pipes 16 is connected with a group of air blowers and dried by the air blowers.

As shown in fig. 2, it is preferable that a partition plate 7 is installed on a link plate 6 (perforated mesh plate) of the slat conveyor body 1. By providing the partition 7 with a certain height, the partition 7 can carry a portion of the tea leaves upwards when passing the lifting part 1.3.

As shown in fig. 3, it is preferable that rollers 8 are installed on both sides of a chain 10 of the scraper chain conveyor body 1, and the rollers 8 run along slide rails 9 on the housing 4. The track of the slide rail 9 is consistent with the overall running track of the scraper chain conveyor body 1 in fig. 1. Through setting up gyro wheel 8, slide rail 9, can reduce the friction and wear of chain, also can make drag conveyor body 1 form horizontal crotch structure simultaneously.

As shown in fig. 4, preferably, a stirring paddle 2 is disposed above the scraper chain conveyor body 1 near the lower bent portion 1.2, the stirring paddle 2 includes a stirring shaft 2.1, and a plurality of bent stirring rods 2.2 are circumferentially disposed on the stirring shaft 2.1. The stirring shaft 2.1 is driven to rotate by a belt transmission mechanism 14 and a second motor 15. The tea falling onto the chain-plate conveyor body 1 can be scattered and spread to a certain thickness by the stirring paddle 2.

As shown in fig. 4, the stirring shaft 2.1 of the stirring paddle 2 is preferably rotatably mounted on the lever frame 3 by means of bearings. The lever frame 3 comprises left and right first connecting beams 3.1, and the two first connecting beams 3.1 are transversely welded into a whole through two second connecting beams 3.2. A fan 17 is directly installed on the two second connecting beams 3.2, and the fan 17 air-dries the tea leaves from top to bottom for withering.

As shown in fig. 4, preferably, the ear plate 3.3 is welded at a position in the middle of the left and right first connecting beams 3.1, the connecting shaft 3.4 is fixed on the left and right ear plates 3.3, and the connecting shaft 3.4 is rotatably connected with the mounting plate 3.5 on the housing 4 through a bearing assembly. The other end of the left and right first connecting beam 3.1 far away from the stirring paddle 2 is provided with a telescopic mechanism 5, and the lever frame 3 is adjusted and rotated through the telescopic mechanism 5.

As shown in fig. 5, the telescoping mechanism 5 includes a connecting rod 5.1 hinged to the left and right ends of the lever frame 3, and the other end of the connecting rod 5.1 is hinged to the cross frame 5.2. The cross frame 5.2 is of an inverted U-shaped structure, screw rods 5.3 are rotatably arranged on the left and right sides of the lower end of the horizontal part of the cross frame 5.2 through bearings, and each screw rod 5.3 is in threaded connection with a connecting plate 5.4 welded on the shell 4. Rotating screw rod 5.3 can make screw rod 5.3 oscilaltion, and then drive crossbearer 5.2, connecting rod 5.1 and reciprocate to make lever frame 3 rotate, thereby adjust the height of the stirring rake 2 of the 3 other ends of lever frame, realize the adjustment of tealeaves thickness on drag chain conveyor body 1.

As shown in fig. 5, since the screw 5.3 is close to the housing 4, for the convenience of operation, a driven bevel gear 5.5 is fixedly mounted on the screw 5.3, a driving bevel gear 5.6 is rotatably mounted on the corresponding vertical part of the cross frame 5.2 through a rotating shaft, and the driven bevel gear 5.5 is engaged with the driving bevel gear 5.6. The handle outside the rotating shaft is rotated to drive the driven bevel gear 5.5 to rotate, so that the screw rod 5.3 rotates and moves up and down, and then the height of the stirring paddle 2 is adjusted.

The working principle and the process are as follows: during operation, tealeaves passes through band conveyer and carries on chain scraper conveyor body 1, and chain scraper conveyor body 1 further conveys tealeaves forward, and when the stirring rake 2, stirring rake 2 breaks up tealeaves and makes tealeaves pass through with certain thickness is even. In the process, the air in the air duct 16 passes through Kong Chuidong tea leaves on the chain plate 6, and the tea leaves lose moisture. The tea leaves continuously fall through the lower bending part 1.2, the lifting part 1.3 and the upper bending part 1.4 of the chain plate conveyor body 1, and the tea leaves are blown by the fan 17 to continuously dissipate moisture in the falling process. The fallen tea leaves fall after passing through the lower bending part 1.2, the lifting part 1.3 and the upper bending part 1.4 again. Repeating the above process, the tea leaves are continuously turned over on the chain scraper conveyor body 1 and withered. After a period of time, the chain scraper conveyor body 1 is reversed, and the withered tea leaves are conveyed out.
