Description

Technical Field

[0026] Motor 1 206 drives the bidirectional screw rod 205 to rotate, and the bidirectional screw rod 205 is threadedly connected to the two L-shaped plates 204, so that the two L-shaped plates 204 are synchronously moved closer to or away from each other, and the wind collecting plates 202 are moved closer to or away from each other accordingly, thereby adjusting the area of ​​the air outlet. The wind speed is kept unchanged by reducing the area and wind flow of the air outlet, thereby not affecting the effect of air selection. The telescopic plate 203 is used to connect the wind collecting plate 202 and the square air duct 201, and the square air duct 201 is used for air outlet.

[0027] The air selection mechanism also includes a fan 209, which is installed on the rear side of the upper surface of the equipment platform 100. The outlet of the fan 209 is fixedly connected to the air supply pipe 208, and the other end of the air supply pipe 208 is fixedly connected to the trumpet pipe 207, which is fixedly connected to the rear end of the square-mouth air duct 201.

[0028] The fan 209 generates airflow, which enters the square-mouth air duct 201 through the air supply pipe 208 and the bell pipe 207 .

[0029] The feeding mechanism includes a closing tube 302, the closing end of the closing tube 302 faces downward, the closing tube 302 is arranged on the front and rear upper sides of the square-mouthed air duct 201, the top of the square-mouthed air duct 201 is fixedly connected with the feeding square tube 301, the feeding square tube 301 is fixedly connected to the equipment platform 100, and the left and right sides of the closing tube 302 are provided with trapezoidal plates 303 connected along the left and right sliding, the bottom end of the trapezoidal plate 303 is fixedly connected to the L-shaped plate 204, the top end of the trapezoidal plate 303 is fixedly connected to the soft surface 304, and the top end of the soft surface 304 is fixedly connected to the inner wall of the feeding square tube 301.

[0030] The closing tube 302 allows the tea leaves in the feeding square tube 301 to enter the air selection channel in a relatively thin layer, thereby reducing the collision between the tea leaves and achieving a better air selection effect.

[0031] The material receiving mechanism includes a flap 401, and both ends of one side of the flap 401 are fixedly connected with a rotating shaft 402, and the rotating shaft 402 is rotatably connected to the equipment platform 100. A motor 2 403 is installed on one side of the flap 401, and the output shaft of the motor 2 403 is fixedly connected to the rotating shaft 402 on the same side.

[0032] The rotating shaft 402 is used to keep the flap 401 flippable, and the second motor 403 provides a rotational force to drive the rotating shaft 402 to rotate, thereby driving the flap 401 to flip, and the flipping facilitates the pouring out of the tea leaves in the collecting bin 404.

[0033] The material receiving mechanism includes a material receiving bin 404 distributed in the longitudinal direction. The material receiving bin 404 is slidably connected to the flap 401 along the longitudinal direction, and the height of the material receiving bin 404 decreases toward the front side.

[0034] The longitudinal arrangement of the receiving bin 404 receives tea leaves of different grades after air selection.

[0035] A bell mouth 405 is provided on the top of the material receiving bin 404 , and an electric telescopic rod 406 is fixedly connected to the rear side of the material receiving bin 404 , and the other end of the electric telescopic rod 406 is fixedly connected to the flap 401 .

[0036] The sequential lowering of the material receiving bins 404 allows the projections of the tops of the bell mouths 405 to overlap each other when the spacing between the material receiving bins 404 is adjusted, thereby preventing tea leaves from falling outside the material receiving bins 404. The electric telescopic rod 406 is used to control the position of the material receiving bins 404.

[0037] A belt conveyor 500 is provided on the upper side of the square air duct 201 , and the front end of the belt conveyor 500 extends to the upper side of the feeding square tube 301 .

[0038] The belt conveyor 500 is used to transport tea leaves into the feeding square tube 301 .

[0039] Working principle:

[0040] After the tea leaves enter the square-mouthed air duct 201, the motor 206 is started, and the motor 206 drives the bidirectional screw rod 205 to rotate, thereby adjusting the spacing of the L-shaped plate 204, and then adjusting the spacing of the trapezoidal plate 303 and the wind-collecting plate 202. According to the transmission speed of the tea leaves, the spacing of the trapezoidal plate 303 is adjusted, so that the tea leaves in the feeding square tube 301 pass through the bottom narrow opening of the closing tube 302, forming a thinner tea layer, and completing air selection under the action of wind flow.

[0041] When the feeding speed of tea leaves slows down, the width of tea leaves coming out of the closing tube 302 is narrowed by adjusting the motor 206. At the same time, since the L-shaped plate 204 is connected to the wind gathering plate 202, the spacing of the wind gathering plate 202 is also adjusted accordingly, thereby changing the cross-sectional area of ​​the air outlet. At this time, reducing the air volume of the fan 209 can also maintain the wind speed of the air outlet, saving energy and not affecting the air selection effect.

[0042] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
