[0013] Specifically, the inner wall of the side wall 106 is fixedly connected with an upper aggregate trough 206, and the upper aggregate trough 206 is arranged directly below the lower end of the first screen 204. The inner groove of the upper aggregate trough 206 is arranged in an arc shape, wherein the high end is connected to the lower part of the first screen 204, and the low end is connected to the first discharge pipe 207. The first discharge pipe 207 is connected to the first aggregate vehicle 201 directly below.

The main slide 301 is fixedly connected to the side wall 106. The main slide 301 is arranged at an angle. The bottom of the main slide 301 is connected to the third discharge pipe 402. The third discharge pipe 402 is connected to the third aggregate vehicle 203 directly below.

[0014] Working principle: When the device is used, the staff starts the lower bracket 103, and the lower bracket 103 drives the cam 105 to rotate. As the cam 105 rotates, the driving rod 108 matched with the cam 105 shakes upward under the action of the cam 105, that is, the driving rod 108 reciprocates up and down. At this time, the staff slowly pours the raw materials through the feed port 109. At this time, the tea leaves are diverted to the first screen 204 on both sides through the partition 107, and the first screen 204 is fixed on the outer frame 302. The outer frame 302 is fixed with a limit block 307, and the driving rod 108 reciprocates up and down. When the driving rod 108 moves up, the limit protrusion 303 fixed thereon contacts the limit block 307, causing the limit block 307 to move outward. At this time, under the action of the limit block 307, the outer frame 302 and the slider 305 slide downward along the guide rail 304. At this time, the spring 306 is compressed. When the driving rod 108 moves downward, the limit block 307 loses the contact with the limit protrusion 303, and the slider 305 is compressed by the spring 306. The outer frame 302 and the limit block 307 move upward, and the limit block 307 is moved upward, so that the limit block 307 is close to the limit protrusion 303. At this time, the first screen 204 shakes left and right along the upper surface to screen out the semi-finished leaves and broken slag. Since the first screen 204 is tilted, as the first screen 204 shakes, the finished leaves remaining on it fall into the upper collecting trough 206 along both sides, slide into the first discharge pipe 207 along the upper collecting trough 206, and finally enter the first collecting vehicle 201, while the semi-finished leaves and broken slag slide down the lower surface. Plate 205 slides into the upper end of the second screen 208, and the second screen 208 shakes similarly. As the second screen 208 shakes, the debris falls onto the main slide 301 along the pores of the second screen 208, and slides into the third discharge pipe 402 and the third aggregate vehicle 203 along the main slide 301. The semi-finished leaves enter the lower aggregate trough 209 as the second screen 208 shakes, and slide into the second discharge pipe 401 and the second aggregate vehicle 202 along the lower aggregate trough 209. The device is simple to operate, efficient in screening, and low in cost.

[0015] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
