2. A method of processing tea using the tea leaf spreading and processing system of claim 1, comprising the steps of:
s1: when the equipment is used, the wind power of the fan (9) is debugged, and then collected tea leaves are poured into the discharging hopper (10);
s2: tea leaves falling from the bottom of the discharging hopper (10) are blown by wind force of a fan (9), the tea leaves with lower water content are lighter and move towards one end of the spreading net rack (2) far away from the fan (9), and the tea leaves with higher water content are heavier and move closer under the action of wind force and self gravity;
s3: the screen plate (301) on the movable frame (3) is obliquely arranged, one higher end of the screen plate (301) is arranged on one side of the fan (9), then according to the paving capacity of tea leaves in the paving net frame (2), the tea leaves on the screen plate (301) are scraped horizontally to the discharge port (11) by utilizing the scraping plate, redundant tea leaves are removed from the paving net frame (2), at the moment, the tea leaves are automatically paved on the screen plate (301) according to the self water content, the tea leaves with low water content are thicker in paving, and the tea leaves with high water content are thinner in paving;
s4: then, the driving motor (4) is controlled to run, so that the output end of the driving motor (4) drives the driving rod (401) to rotate, the driving rod (401) drives the U-shaped rod (402) to rotate when rotating, a connecting rod (403) connected with the U-shaped rod (402) generates pulling force or pushing force on the push rod (404), and then the push rod (404) drives the movable frame (3) to reciprocate up and down, so that tea leaves on the screen plate (301) shake up and down, and air flow between the tea leaves is ensured;
s5: when the driving rod (401) rotates, the rotating rod (7) is driven to rotate through the synchronous wheel (6) and the belt, the sleeve (701) in threaded connection with the rotating rod (7) slides on the spreading net rack (2), the rotating shaft (704) is driven to rotate when the sleeve (701) moves, the first bevel gear (702) is driven to rotate through the guide bar (7021) when the rotating rod (7) rotates, the first bevel gear (702) is meshed with the second bevel gear (703) on the rotating shaft (704), the rotating shaft (704) drives the turning rod (705) to rotate, and when the net plate (301) moves upwards, the turning rod (705) turns tea leaves at the bottom of the net plate (301), so that tea leaves at the bottom layer are turned to the upper layer, and the tea leaves can be fully and evenly dried;
s6: when the movable frame (3) moves up and down, the sleeve (8) moves relative to the piston (801), external air can be extracted through the air inlet valve when the sleeve (8) moves up relative to the piston (801), when the sleeve (8) moves down relative to the piston (801), the piston (801) discharges air in the sleeve (8) into the rotating shaft (704) through the air outlet valve and the air guide pipe (803), and the air fully flows in tea leaves which are paved and turned through the air outlet hole (7041) along with the movement and rotation of the rotating shaft (704), so that the loss of water content of the tea leaves is accelerated, and the spreading speed is improved.
