The dust suction component 3 includes an air pump 301, a dust collection box 302 and a dust cover 304. The air pump 301 and the dust collection box 302 are both provided on the screening box 1. At the top of the screening box 1, the dust cover 304 is arranged inside the screening box 1, the input end and the output end of the air pump 301 extend to the dust cover 304 and the inside of the dust collection box 302 respectively, the dust collection box 302 is provided with a filter 303, the dust cover 304 is provided with a vent 305, and the screening box 1 is provided with a screening component 5 for screening and removing impurities from jasmine tea. The screening component 5 includes a fixing ring 501 and a mounting frame 503. The fixing ring 501 is arranged on the screening box 1. On one side of the interior of the sub-box 1, the mounting frame 503 is rotatably arranged on the other side of the interior of the screening box 1, and a screening net 505 is provided on the mounting frame 503, and a spiral conveying sheet 506 is provided inside the screening net 505, and a connecting frame 504 is provided inside the mounting frame 503. A driving member 6 that drives the screening net 505 to rotate is provided in the connecting box 2. The driving member 6 includes a connecting shaft 601 provided on one side of the connecting frame 504 and a second motor 603 provided on one side of the interior of the connecting box 2. The spindle end of the second motor 603 is connected to the second gear 604, and one end of the connecting shaft 601 is connected to the first gear 602 that meshes with the second gear 604. An auxiliary blanking member 4 for assisting jasmine tea in blanking is provided on the feed hopper 101, and the auxiliary blanking member 4 includes a first motor 401 provided on the feed hopper 101 and a blanking dial plate 402 rotatably provided inside it, and the blanking dial plate 402 is connected to the spindle end of the first motor 401;Specifically, when the jasmine tea enters the screening box 1 through the feed hopper 101 for screening, the auxiliary unloading component 4 is able to drive the jasmine tea to be unloaded in batches, and at the same time, the driving component 6 is able to drive the screening net 505 and the spiral conveying piece 506 to rotate, and the jasmine tea can be driven to be spirally conveyed during the rotation. During the continuous rotation, the impurities on the jasmine tea can pass through the screening net 505 and fall into the impurity collection box 102 below. In this process, the dust collection component 3 is able to absorb the dust and impurities raised during the rotation, thereby further ensuring the degree of impurity removal. The spiral conveyor 506 continuously drives the jasmine tea forward, thereby achieving sustainable impurity removal from the jasmine tea. During the pushing process of the spiral conveyor 506, the clean jasmine tea automatically falls into the jasmine tea collection box 201 for collection. During the impurity removal process, there is no need to stop and start the machine at intervals, ensuring the efficient impurity removal. When the driving member 6 is in operation, the second motor 603 drives the second gear 604 to rotate. The second gear 604 meshes with the first gear 602, thereby driving the connecting shaft 601 to rotate, thereby driving the screening net 505 and the spiral conveyor 506 to rotate.

[0025] like Figure 2 As shown, the impurity collection box 102 and the jasmine tea collection box 201 are respectively arranged directly below the screening net 505 and at the outlet end.

[0026] like Figure 2 As shown, the dust hood 304 is arranged directly above the screening mesh 505, and its cross-section is a semicircular ring; specifically, the air pump 301 can draw the dust and impurities raised during the screening process into the interior of the dust collection box 302, and then under the action of the filter mesh 303, the clean air can be discharged outward. The dust hood 304 is a semi-arc design, which can wrap the screening mesh 505, thereby increasing the contact area with the air and ensuring the suction effect of dust and impurities.

[0027] like Figure 2 As shown, the feed hopper 101 includes a funnel member with a trapezoidal vertical section and a tubular member with a rectangular vertical section.

[0028] like Figure 4 As shown, the unloading plate 402 is composed of two discs whose diameters are consistent with the inner diameters of the tubular part on the feed hopper 101, and the two discs are designed to cross vertically; specifically, the first motor 401 can drive the unloading plate 402 to rotate, and the discs rotate alternately, thereby realizing batch unloading of jasmine tea. At the same time, the spiral conveying sheet 506 rotates, which can ensure the screening effect of jasmine tea and avoid the accumulation of jasmine tea affecting its screening effect.

[0029] like Figure 2 and 3 As shown, the mounting frame 503 is rotatably connected to the fixing ring 501 , a material discharge chute 502 is provided on the fixing ring 501 , and the bottom end of the feed hopper 101 extends to the interior of the material discharge chute 502 .

[0030] In summary: when the jasmine tea enters the screening box 1 through the feed hopper 101 for screening, the auxiliary unloading component 4 provided can drive the jasmine tea to be unloaded in batches, and at the same time, the driving component 6 provided can drive the screening net 505 and the spiral conveying piece 506 to rotate, and can drive the jasmine tea to be spirally conveyed during its rotation. During the continuous rotation, the impurities on the jasmine tea can pass through the screening net 505 and fall into the impurity collection box 102 below. During this process, the dust suction component 3 provided can suck away the dust and impurities raised during the rotation, further ensuring the degree of impurity removal. During this process, since the spiral conveying piece 506 can continuously drive the jasmine tea to be transported forward, sustainable impurity removal of the jasmine tea can be achieved. During the pushing process of the spiral conveying piece 506, the clean jasmine tea can automatically fall into the interior of the jasmine tea collection box 201 for collection. During the impurity removal process, there is no need to stop and start the machine at intervals, thereby ensuring the impurity removal efficiency.
