The lower part is narrower to reduce the speed of the jujube falling, so that the jujube will not be damaged when it falls onto the conveyor belt due to excessive speed and impact force.

[0030] 7. The cross-sectional area of the outfeed channel reaches a minimum at the outfeed opening, which serves as a limiting function during the falling of the jujubes. The jujubes can only fall through this small opening onto the conveyor belt corresponding to the category of jujubes, preventing the mixing of jujubes of different categories and achieving better sorting results.

[0039] The feeding channel 1 is provided with a feeding port 3 opposite to the spraying position of the sorting nozzle, the feeding port 3 of the feeding channel 1 is two, the two feeding ports 3 are opposite, the discharging channel 2 is located below the feeding channel 1 and is in communication with the feeding channel 1, the bottom of the discharging channel 2 is provided with a discharging port 4, a blocking mechanism 5 is arranged between the two feeding ports 3, the position of the blocking mechanism 5 is opposite to the position of the feeding port 3, and the blocking mechanism 5 is provided with a dust collection mechanism 6.

[0041] The working principle of the utility model is as follows:

[0042] The collision process of red dates and the baffle 51: when the red dates are sprayed by the sorting nozzle to the corresponding feeding port 3 of the corresponding category, the red dates collide with the corresponding baffle 51, the dust on the red dates is bounced out and scattered in the surrounding air, and then is sucked away by the dust collector 62 through the through hole 53 on the baffle 51, the cavity 52 and the dust collection pipe 61; at the same time, the impact force of the red dates hitting the baffle 51 drives the baffle 51 to swing in the movement direction of the red dates with a small amplitude, and the movement of the red dates to the baffle 51 is blocked, and the red dates can only move downward along the discharging channel 2.

[0043] After the collision of the red dates and the baffle 51: the red dates contact the inner wall of the blanking channel 2 at a small speed, and slide to the discharging port 4 from the inner wall of the blanking channel 2, and fall into the conveying belt relatively accurately through the small discharging port 4, in the process, since the channel becomes narrower and narrower in the process of the red dates sliding downward, the speed of the red dates sliding downward becomes slower and slower, and finally the red dates separate from the discharging port 4 into the conveying belt at a small speed.

[0044] In addition, since the inner wall structure of the discharging channel 2 is relatively smooth, there is no relatively sharp or angular part, and the red dates will not be scratched or damaged in the process of contacting and sliding down the inner wall of the blanking channel 2.
