[0034] As Figures 1 to 14As shown in the figure, a tea quality detection device includes a primary tea screening mechanism 1. The primary tea screening mechanism 1 includes a screening inclined plate 101. On one side of the screening inclined plate 101, a tea subdivision mechanism 2 is fixedly installed. The tea subdivision mechanism 2 includes a secondary screening plate 201. At the rear end of the secondary screening plate 201, a tea detection mechanism 3 is fixedly installed. Screening inclined grooves 102 are arranged in a staggered manner at the top of the screening inclined plate 101. At the position corresponding to the screening inclined grooves 102 at the bottom of the screening inclined plate 101, a plurality of tea limiting blocks 120 are fixedly installed. The tea limiting blocks 120 are used to limit the screening speed of the tea. There is a leaf-shaped groove in the middle of the tea limiting blocks 120, and a larger leaf-shaped groove is provided at the bottom of the tea limiting blocks 120. The top of the leaf-shaped groove at the bottom of the tea limiting blocks 120 is an inclined surface. A discharge groove is provided on one side of the tea limiting blocks 120.

A plurality of positioning protrusions are fixedly installed on the surface of the first transmission belt 106, which are used to fix the tea on the surface of the first transmission belt 106 to prevent the tea from shifting. A plurality of air extraction pipes 119 are fixedly installed at the bottom of the screening inclined plate 101. The air extraction pipes 119 are inserted inside the first transmission belt 106, which is used to adsorb the tea on the top of the first transmission belt 106, facilitate the stable movement of the first transmission belt 106 to drive the tea, and adsorb the sundries attached to the surface of the tea. A tea turning plate 107 is rotatably installed at the top of the screening inclined plate 101. A plurality of positioning rotating rods 108 are rotatably installed horizontally on the tea turning plate 107. Gears are fixedly installed on the positioning rotating rods 108. The gears on the positioning rotating rods 108 mesh with each other. A second driving ring motor 109 is fixedly installed at the rear end of the tea turning plate 107.

A transmission rod is hinged between the eccentric wheel 111 and the tea turning plate 107. Before the tea is detected, it is necessary to screen and arrange the tea to facilitate the accurate detection of the tea quality. After the tea is poured onto the surface of the screening inclined plate 101, it slides on the surface of the screening inclined plate 101 by gravity. When the tea slides into the screening inclined groove 102, the position of the tea is restricted by the leaf-shaped groove on the tea limiting block 120, so that the tea can be accurately stacked together.

The adjusting rubber belt 103 is rotatably installed between two side-by-side screening inclined chutes 102. By starting the fourth driving motor 114 to drive the second adjusting rotating rod 113 to rotate, the second adjusting rotating rod 113 rotates to drive the first adjusting rotating rod 112 to rotate synchronously, and drives the adjusting rubber belt 103 to roll on the screening inclined plate 101 through the first adjusting support wheels 115 fixedly installed on the first adjusting rotating rod 112. At the same time, the gear on the second adjusting rotating rod 113 drives the hollow adjusting short rod 116 to rotate in the opposite direction on the first adjusting rotating rod 112, drives the second adjusting support wheel 117 to rotate in the opposite direction on the first adjusting rotating rod 112, and drives the corresponding adjusting rubber belt 103 to roll in the opposite direction on the screening inclined plate 101. The adjusting rubber belts 103 that alternately roll in the opposite direction on the screening inclined plate 101 can adjust the horizontal tea leaves to the vertical direction, so that the tea leaves can enter the screening inclined chute 102 more smoothly.

After that, start the electric push rod 309 to drive the adjusting pressing plate 310 to retract a certain distance, so that the sliding adjustment rod 311 at the rear end of the adjusting pressing plate 310 rises through the spring, drives the arc-shaped clamping jaw 313 to retract into the clamping slider 312 through the torsion spring, so that the cut half piece of tea leaves is discharged through the waste discharge port 319, exposing the cross-section at the top of the other half of the tea leaves. After that, detect the internal components and structure of the tea leaves through the detection probe 316.,

[0039] Working principle: When quality inspection of tea leaves is required, first pour the tea leaves to be screened and detected on the top of the screening inclined plate 101. After that, start the fourth driving motor 114 to drive the first adjusting rotating rod 112 and the second adjusting rotating rod 113 to rotate, drive a plurality of adjusting rubber belts 103 to roll on the screening inclined plate 101, adjust the angle of the tea leaves, so that the tea leaves slide into the screening inclined groove 102, and further adjust the angle and discharge speed of the tea leaves through the tea leaf limiting block 120. At the same time, start the first driving motor 104 to drive the first transmission rod 105 to rotate. The rotation of the first transmission rod 105 drives the first transmission mesh belt 106 to rotate. Fix the position of the tea leaves through the bumps on the first transmission mesh belt 106. At the same time, start the air extraction pipe 119 to adsorb the tea leaves on the surface of the first transmission mesh belt 106, and at the same time suck the impurities on the surface of the tea leaves through the air extraction pipe 119 and discharge them through the air extraction pipe 119.

During this period, start the second driving ring motor 109 to drive the positioning rotating rod 108 to rotate, adjust the angle of the tea leaves, and adjust the tea leaves to the gap between the positioning rotating rods 108 to fix the position. After that, start the third driving motor 110 to drive the eccentric wheel 111 to rotate. When the eccentric wheel 111 rotates, drive the tea leaf turning plate 107 to flip on the screening inclined plate 101 through the transmission rod, and flip the tea leaves inside the tea leaf turning plate 107 to the upper half of the screening inclined plate 101 to re-screen the remaining tea leaves.

[0040] The tea leaves are conveyed to the corresponding horizontal partition groove 202 through the first transmission mesh belt 106, and different lengths of tea leaves are separated into different vertical partition grooves 203 through a plurality of length screening plates 204, and are conveyed to the second tea transmission belt 301 through the first tea transmission belt 205.

[0041] The tea leaves conveyed to the second tea transmission belt 301 will undergo spot-check quality inspection through the first detection support frame 302, and the defects and structure on the surface of the tea leaves will be detected by the appearance detection device 304 when passing through the second detection support frame 303.

[0042] When the tea leaves pass through the first detection support frame 302, the rotation motor 307 is started to drive the second rotating support rod 306 to rotate on the first rotating support rod 305, driving the detection counterweight support 308 to slide to the midline position of the second tea conveyor belt 301 to intercept the tea leaves. When the tea leaves enter the bottom of the detection counterweight support 308, the electric push rod 309 is started to drive the clamping slider 312 to slide downward in the detection counterweight support 308, and the tea leaves are grabbed by the arc-shaped jaws 313, and the tea leaves are obliquely cut by the oblique cutting knife 318, and the structure and components inside the tea leaves are detected by the detection probe 316.
