[0018] Furthermore, the upper surface of the pouring pipe is connected to a material expansion cover, and the angle between the pouring pipe and the top of the right side of the feed box is an acute angle.

[0019] By adopting this technical solution, the expansion cover can be arranged to facilitate the feeding of large quantities of white tea into the inner cavity of the feeding tube.

[0020] Furthermore, the left end of the support platform is hingedly connected to a box door via a door hinge, and a collection box is placed in the inner cavity of the support platform.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1 A conveying device for sorting white tea in this embodiment includes a support table 1. The upper surface of the support table 1 is connected to a screening box 2. The inner cavity of the screening box 2 is provided with an inclined screen plate 3. A vibration mechanism 4 for vibrating the screen plate 3 is provided at the bottom of the left side of the screening box 2. A feeding mechanism 5 for uniform feeding is provided on the upper surface of the screening box 2. A belt rack 6 is provided on the right side of the support table 1.

[0032] See also Figure 2-3 In order to prevent the white tea from getting stuck in the sieve holes of the sieve plate 3, the vibration mechanism 4 in this embodiment includes a driving member 41, two limiting members 42 and two supporting blocks 43. The driving member 41 is arranged at the bottom of the left side of the screening box 2 and is used to drive the movement of the sieve plate 3. The two supporting blocks 43 are fixed on the opposite sides of the left and right side walls of the inner cavity of the screening box 2. The limiting member 42 is arranged on the upper surface of the supporting block 43 and is used to limit the movement of the sieve plate 3.

[0033] In this embodiment, the driving member 41 includes a driving motor 411, a shaft 412, two cams 413 and two knocking blocks 414. The driving motor 411 is fixed to the bottom of the left side of the screening box 2, and both ends of the shaft 412 are rotatably connected to the side opposite to the left and right side walls of the inner cavity of the screening box 2 through bearings. The output shaft of the driving motor 411 passes through the screening box 2 and extends to the inner cavity of the screening box 2 and is fixed to the shaft 412. The cam 413 is fixed to the outer surface of the shaft 412. When the sieve plate 3 screens white tea, the driving motor 411 is first started, and the output shaft of the driving motor 411 rotates, thereby driving the shaft 412 to rotate. The rotation of the shaft 412 drives the two cams 413 fixed on its outer surface to rotate, and the knocking blocks 414 are fixed to the lower surface of the sieve plate 3. When the protrusions of the two cams 413 rotate to the highest point, the two knocking blocks 414 can be pushed, so that the two knocking blocks 414 drive the sieve plate 3 to move upward.

[0034] The two cams 413 are symmetrically distributed at the left and right ends of the vertical center axis of the shaft rod 412 , and the knocking block 414 is located just above the cam 413 .

[0035] In this embodiment, the limiting member 42 includes a telescopic rod 421 and a return spring 422. The telescopic rod 421 is fixed on the upper surface of the support block 43. The upper surface of the telescopic rod 421 is fixed to the lower surface of the sieve plate 3. The return spring 422 is movably sleeved on the outer surface of the telescopic rod 421. When the sieve plate 3 moves upward, the telescopic rod 421 will be extended and the return spring 422 will be stretched. The return spring 422 will rebound after being stressed, driving the telescopic rod 421 to shorten, thereby moving the sieve plate 3 downward. The sieve plate 3 is moved up and down by rotating the cam 413, so that the residual stems and impurities can pass through the sieve plate 3 and fall into the collection box in the inner cavity of the support platform 1.

[0036] Among them, the two ends of the return spring 422 are fixedly connected to the opposite side of the screen plate 3 and the support block 43 respectively. A discharge port is opened on the right side of the screening box 2, and an inclined guide plate is fixed to the right side of the discharge port. The larger white tea falls onto the guide plate through the discharge port, and falls on the belt of the belt rack 6 under the guidance of the guide plate, so as to proceed to the next step.

[0037] It should be noted that the heights of the telescopic rods 421 and the return springs 422 at the left and right ends are different.

[0038] See also Figure 4The feeding mechanism 5 in this embodiment includes a feeding box 51, a rotating motor 52, a rotating rod 53, a pushing ring plate 54 and a pouring pipe 55. The feeding box 51 is connected to the upper surface of the screening box 2, and the rotating motor 52 is fixed to the upper surface of the feeding box 51. The output shaft of the rotating motor 52 passes through the feeding box 51 and extends to the inner cavity of the feeding box 51 and is fixed to the rotating rod 53. The pushing ring plate 54 is fixed to the outer surface of the rotating rod 53. One end of the pouring pipe 55 is connected to the top of the right side of the feeding box 51. The staff can pour white tea into the pouring pipe 55. The white tea entering the inner cavity of the pouring pipe 55 can fall on the push ring plate 54 as guided by the pouring pipe 55. The rotating output shaft of the rotating motor 52 can rotate the rotating rod 53. The rotation of the rotating rod 53 causes the pushing ring plate 54 to rotate, so that the white tea can fall evenly on the sieve plate 3 as the pushing ring plate 54 rotates.

[0039] In this embodiment, the upper surface of the pouring pipe 55 is connected to the expansion cover, the angle between the pouring pipe 55 and the top right side of the feed box 51 is an acute angle, the left end of the support platform 1 is hingedly connected to the box door through a door hinge, and a collection box is placed in the inner cavity of the support platform 1.

[0040] It should be noted that the outer surfaces of the rotating motor 52 and the driving motor 411 are both provided with protection boxes.

[0041] It can be understood that the white tea can evenly fall onto the sieve plate 3 as the pushing ring plate 54 rotates, thereby preventing a large amount of white tea from piling up on the sieve plate 3 and improving the screening quality of the sieve plate 3 .

[0042] The working principle of the above embodiment is:

[0043] (1) In order to avoid the sieve holes of the sieve plate 3 being blocked, when the sieve plate 3 is screening white tea, the driving motor 411 is first started, and the output shaft of the driving motor 411 rotates, thereby driving the shaft 412 to rotate. The rotation of the shaft 412 drives the two cams 413 fixed on its outer surface to rotate. When the protrusions of the two cams 413 rotate to the highest point, the two knocking blocks 414 can be pushed, so that the two knocking blocks 414 drive the sieve plate 3 to move upward. At this time, the telescopic rod 421 will be extended and the return spring 422 will be stretched. The return spring 422 will rebound after being stressed, driving the telescopic rod 421 to shorten, thereby moving the sieve plate 3 downward. The rotation of the cam 413 makes the sieve plate 3 move up and down, so that the residual stems and impurities can pass through the sieve plate 3 and fall into the collection box in the inner cavity of the support platform 1, while the larger white tea leaves fall onto the guide plate through the discharge port and fall on the belt of the belt rack 6 under the guidance of the guide plate, so as to proceed to the next step.

[0044] (2) In order to prevent too much white tea from falling onto the sieve plate 3, the staff can pour the white tea into the pouring tube 55 and then start the rotating motor 52. The white tea entering the inner cavity of the pouring tube 55 can fall onto the push ring plate 54 under the guidance of the pouring tube 55. By rotating the output shaft of the rotating motor 52, the rotating rod 53 can be rotated. The rotation of the rotating rod 53 causes the push ring plate 54 to rotate, so that the white tea can fall evenly on the sieve plate 3 as the push ring plate 54 rotates.
