[0021] like Figure 1 and Figure 2 As shown, the bracket assembly includes a first bracket 1 and a second bracket 2. The first bracket 1 and the second bracket 2 are integrally processed and both are welded by profiles. The overall strength is high and the stability is good. The second bracket 2 is located on one side of the first bracket 1. The upper surface of the second bracket 2 is processed into an inclined form, that is, it is inclined downward from the side close to the first bracket 1 to the direction away from the first bracket 1. The first-level sorting component is installed on the first bracket 1, and the second-level sorting component is installed on the second bracket 2.

[0022] like Figure 1 , Figure 2 , Figure 4-Figure 6As shown, the primary sorting assembly includes a driving motor 3, a sorting cover 4, a sorting barrel 5 and a stirring shaft 6. The driving motor 3 and the sorting cover 4 are fixedly connected to the top of the first bracket 1. The driving motor 3 is located on one side of the sorting cover 4. The sorting barrel 5 is installed inside the sorting cover 4 and is fixed relative to the sorting cover 4. The circumferential wall of the sorting barrel 5 is processed with uniformly distributed first leak holes 8. The feeding funnel 7 is installed on the side of the sorting cover 4 away from the driving motor 3. The feeding funnel 7 is connected to the inside of the sorting barrel 5 to facilitate the raw materials to pass through. The feeding funnel 7 enters the sorting drum 5, and the stirring shaft 6 is installed inside the sorting drum 5. The stirring shaft 6 can rotate relative to the sorting drum 5, and the rotation of the stirring shaft 6 is realized by the driving motor 3. Specifically, one end of the stirring shaft 6 extends outward through the sorting drum 5 and the sorting cover 4 in sequence to the outside of the sorting cover 4. A first driven pulley 13 is fixedly connected to the protruding end of the stirring shaft 6, and a first driving pulley 12 is fixedly connected to the output shaft of the driving motor 3. The first driving pulley 12 and the first driven pulley 13 are connected by a transmission belt. The driving motor 3 drives the first driving pulley 12 to rotate, and the first driven pulley 13 is driven by the power transmission of the transmission belt to drive the stirring shaft 6 to rotate. A plurality of stirring rods 9 are connected to the stirring shaft 6, and a plurality of stirring rods 9 are grouped into a plurality of groups. The plurality of stirring rods 9 in the same group are distributed in a line along the axial direction of the stirring shaft 6, and the plurality of groups of stirring rods 9 are staggered on the stirring shaft 6. An extrusion plate 10 is connected between the ends of the stirring rods 9 in the same group, and the extrusion plate 10 faces the sorting drum. The side of the inner wall of the sorting cylinder 5 is processed into an arc shape concentric with the sorting cylinder 5. A rubber plate 11 is installed on the side of the extrusion plate 10 facing the inner wall of the sorting cylinder 5. After installation, a certain gap is left between the rubber plate 11 and the inner wall of the sorting cylinder 5. The stirring shaft 6 rotates so that the raw materials can be kneaded between the rubber plate 11 and the inner wall of the sorting cylinder 5 to achieve the crushing of the sour jujube raw materials.

The receiving plate 15 is installed tilted relative to the first bracket 1, and the receiving plate 15 is installed with multiple layers. The multiple layers of the receiving plates 15 are installed at intervals up and down. The crushed and separated pulp or juice falls onto the receiving plate 15 through the first leakage hole 8. The tilted receiving plate 15 allows the pulp or juice to slide and be collected for subsequent use. The impact of the fall can be reduced after being buffered by the multiple layers of the receiving plates 15 to prevent splashing and environmental pollution.

[0023] like Figure 1 , Figure 2 and Figure 4As shown, the power assembly includes a power motor 16, a reducer 17 and a transmission shaft 18. The power motor 16 and the reducer 17 are both installed on the first bracket 1. A second driving pulley 20 is fixedly installed on the output shaft of the power motor 16, and a second driven pulley 21 is fixedly installed on the input shaft of the reducer 17. The second driving pulley 20 and the second driven pulley 21 are connected through a transmission belt transmission.

One end of the transmission shaft 18 is connected to the output shaft of the reducer 17 through a coupling. The power motor 16 drives the second driving pulley 20 to rotate, and drives the reducer 17 to work through the power transmission of the transmission belt. After the reducer 17 decelerates and increases the torque, it drives the transmission shaft 18 to rotate. Two gears 19 are installed on the transmission shaft 18 at intervals to drive the secondary sorting component to move.

[0024] like Figure 1-Figure 4 As shown, the secondary sorting component includes a roller 22, a support mechanism and a brush roller 23. The roller 22 is connected to the second bracket 2 through the support mechanism. The number of the support mechanisms is two, and the two support mechanisms support the two ends of the roller 22 respectively. The roller 22 is processed into a cylindrical structure with open ends. Second leak holes 24 are evenly distributed on the circumferential wall of the roller 22. Gear rings 25 are connected to the outer circumferences of both ends of the roller 22. The gear rings 25 are meshed with the gear 19. The roller 22 is driven to rotate by the meshing of the gear 19 and the gear ring 25. A support ring 26 is processed on the outer circumference of the end of the roller 22 and on one side of the gear ring 25. The support mechanism is supported on the support ring 26. The support mechanism includes two support rollers 27. The two support rollers 27 are symmetrically connected to the second bracket 2. The support rollers 27 can rotate relative to the second bracket 2, so that the support rollers 27 are in rolling contact with the support ring 26. A support rod 28 is installed, and both ends of the support rod 28 are fixedly connected to both ends of the second bracket 2. The entire support rod 28 is installed through the inside of the roller 22, and the number of brush rollers 23 is set to be multiple. Multiple brush rollers 23 are connected to the support rod 28 through a bearing seat. When the brush rollers 23 are installed on the support rod 28, they are installed on both sides of the support rod 28 and are installed sequentially from top to bottom to ensure that the brush rollers 23 can cover the length direction of the roller 22. In order to improve the effect of separating the pulp and the core, the number of brush rollers 23 is installed more at the end of the roller 22 close to the sorting drum 5, and decreases sequentially in the direction away from the sorting drum 5. After the brush roller 23 is installed, its outer circumferential surface is in close contact with the inner wall of the roller 22 to generate friction. When the roller 22 rotates, the brush roller 23 is driven to rotate by the friction between the brush roller 23 and the inner wall of the roller 22, and the sour jujube is repeatedly rubbed by the brush on the brush roller 23, so that the pulp and the core are effectively separated.

[0025] like Figure 6As shown, a feed pipe 14 is installed on the sorting drum 5 for conveying the raw materials in the sorting drum 5 to the roller 22. The feed pipe 14 is installed at one end of the sorting drum 5 away from the feed hopper 7 and is located at the bottom of the sorting drum 5. The end of the feed pipe 14 away from the sorting drum 5 passes through the sorting cover 4 and extends to the interior of the roller 22.

[0026] like Figure 1 As shown, a protective cover 29 is installed on the second bracket 2. The protective cover 29 covers the outside of the roller 22 as a whole to protect the roller 22, prevent the damage caused by the rotation of the roller 22, and prevent the roller 22 from being contaminated by environmental dust. The protective cover 29 can be connected to the second bracket 2 by bolts to achieve the detachable protective cover 29, which is convenient for maintenance of the roller 22, etc.

[0027] The working principle of the present invention is: When in use, the sour jujube raw material is manually or automatically put into the feeding funnel 7, the raw material enters the sorting drum 5 through the feeding funnel 7, the driving motor 3 is started, the driving motor 3 drives the stirring shaft 6 to rotate, and the stirring rod 9 stirs the raw material to prevent the raw material from accumulating at the bottom of the sorting drum 5. While the stirring rod 9 stirs the raw material, the rubber plate 11 installed on the extrusion plate 10 and the inner wall of the sorting drum 5 squeeze and rub the sour jujube raw material, so that the sour jujube raw material is broken, and the slurry and the fallen fine pulp can fall to the receiving plate 15 through the first leakage hole 8 and are uniformly collected by the receiving plate 15. The broken kernels still with most of the pulp enter the roller 22 through the feeding pipe 14. Since the roller 22 is installed at an angle, The raw materials roll downward along the axis of the roller 22 under the action of gravity, and the power motor 16 is started. The power motor 16 drives the transmission shaft 18 to rotate through the reducer 17, and drives the roller 22 to rotate through the meshing of the gear 19 and the gear ring 25. The brush roller 23 is driven to rotate by the friction between the brush roller 23 and the roller 22. During the rotation of the brush roller 23, the bristles rub the broken sour jujube to separate the sour jujube pulp and the core. The pulp is rubbed and squeezed into a meat paste and falls to the bottom of the roller 22 through the second leakage hole 24 for unified collection. The separated cores fall out from the bottom of the roller 22 under the action of gravity. After unified collection, it is convenient for subsequent processing to achieve the separation and extraction of the pulp and the core.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention.
