The first swing arm 206 of the application is fixed with the rotating shaft 205, and rotates with the rotation of the rotating shaft 205.

[0030] Specifically, the position relationship in the attached Figure 2 The process of synchronous rotation of several bunkers 40 is described as follows: one of the rotating shafts 205 rotates under the drive of the first drive assembly, the rotating shaft 205 drives the first swing arm 206 to swing, the first swing arm 206 drives the first connecting rod 207 to move transversely, so that several first swing arms 206 and several rotating shafts 205 move synchronously under the drive of the first connecting rod 207.

[0031] As shown in Figure 4 And as shown in Figure 5 The shielding part 30 includes second drive assembly, several second swing arms 305, several third swing arms 306, second connecting rod 307, several second swing arms 305 are coaxially arranged one by one with several rotating shafts 205, one end of each second swing arm 305 is connected with third swing arm 306, the other end of each second swing arm 305 is rotationally connected with second connecting rod 307, the other end of each third swing arm 306 is connected with baffle 50, several third swing arms 306 correspond to the openings of several bunkers 40 one by one, the second connecting rod 307 is transversely arranged, and the second drive member is used to drive one of the second swing arms 305 to swing. As shown in Figure 4 The opening on the right side of the bunker 40 swings left and right, the second swing arm 305 is located at the back side of the bunker 40, the third swing arm 306 is located at the back side of the bunker 40, and the baffle 50 is located at the right side of the bunker 40, so it can be seen that the second swing arm 305 and the third swing arm 306 do not interfere with the rotation stroke of the bunker 40, and the baffle 50 also does not interfere with the rotation stroke of the bunker 40.

[0032] Specifically, the front-back relationship in the attached Figure 4The positional relationship in is based on the description of the process of synchronous rotation of several baffles 50: one of the second swing arms 305 swings under the action of the second driving component, driving the third swing arm 306 connected to the second swing arm 305 and the baffle 50 to rotate synchronously, and at the same time driving the second connecting rod 307 to move laterally, so that under the drive of the second connecting rod 307, several second swing arms 305, third swing arms 306, and baffles 50 move synchronously.

[0033] Therefore, in the initial state, the hopper 40 is arranged vertically and the baffle 50 is at an angle of 30° to the vertical direction.
