[0002] The vitamin content of red dates is very high, and it has the reputation of "natural vitamin pill" and has the effect of nourishing yin and yang. With the improvement of people's living standards, the demand for red dates is increasing day by day. After being picked, red dates need to be cleaned and classified. Usually, they are classified into different grades according to the size of red dates to achieve classification and grading.

[0003] Existing red date sorting machines can quickly sort red dates, but most of them lack an effective cleaning mechanism, and subsequent re-cleaning of red dates is required, which is rather cumbersome. Moreover, existing red date sorting machines occupy a large area and are more suitable for large-scale red date screening. The operating cost of the whole machine is relatively high. When some small-scale self-employed individuals use existing red date sorting machines to screen red dates, the production cost of processed red dates is increased and their economic benefits are reduced. In view of the above situation, a red date classification and grading device for food processing is needed. Summary of the Invention

Specific embodiments

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Refer to Figures 1-4 , a red date classification and grading device for food processing, including a cleaning tank 1 with an open top. Inside the cleaning tank 1, there is a first separation cylinder 6 and a second separation cylinder 5. A plurality of first discharge ports 18 are opened on the side wall of the first separation cylinder 6, and a plurality of second discharge ports 17 are opened on the side wall of the second separation cylinder 5. One side of 1 is fixed with a blanking port 10. The end of the blanking port 10 penetrates through the cleaning tank 1, the second separation cylinder 5, the first separation cylinder 6 and extends into its interior and can be slidably connected to the first separation cylinder 6. Red dates are placed into the second separation cylinder 5 through the blanking port 10 to achieve the addition of red dates. And before the water in the cleaning tank 1 completely submerges the first separation cylinder 6, the inside of the blanking port 10 is blocked by a baffle to prevent the internal red dates from floating in the blanking port 10 under the action of buoyancy. The outer diameter of the second separation cylinder 5 is smaller than the inner diameter of the first separation cylinder 6, and the second separation cylinder 5 and the first separation cylinder 6 can be closely attached to ensure the effectiveness of subsequent cleaning and sorting.

[0024] On both sides of the first separation cylinder 6, there are guide rods 4 fixedly connected. Both ends of the two guide rods 4 penetrate through the cleaning tank 1 and are hermetically and slidably connected thereto. On the left side of the two guide rods 4, there is an adjusting plate 11 fixedly connected. An adjusting mechanism is provided on the adjusting plate 11 that can change the position of the first separation cylinder 6 by adjusting the positions of the two guide rods 4. The adjusting mechanism includes a threaded rod 12 rotatably connected to the side wall of the cleaning tank 1. The end of the threaded rod 12 penetrates through the adjusting plate 11 and is threadedly connected thereto. The adjusting plate 11 is located outside the cleaning tank 1. Rotating the threaded rod 12 can change the position of the first separation cylinder 6 through the adjusting plate 11 and the two guide rods 4. By changing the relative distance between the first discharge port 18 on the first separation cylinder 6 and the second discharge port 17 on the second separation cylinder 5, the size of the sorted red dates can be controlled by changing the size between them. The red dates smaller than the gap can leave the second separation cylinder 5 and the first separation cylinder 6 and float to the water surface under the action of buoyancy, thereby achieving the sorting of red dates. By rotating the threaded rod 12, the sorting of red dates can be directly realized.

[0025] On the right side wall of the second separation cylinder 5, there is a drive shaft 3 fixedly connected. The right side of the drive shaft 3 penetrates through the cleaning tank 1 and is hermetically and rotatably connected thereto. On the ground on one side of the cleaning tank 1, there is a motor 2 fixedly installed. Belt pulleys are fixedly installed on both the motor 2 and the drive shaft 3. The two belt pulleys are driven by a belt, thereby realizing the continuous rotation of the second separation cylinder 5 within the first separation cylinder 6. During the rotation of the second separation cylinder 5, on the one hand, the cleaning of red dates is realized, and the sediment on the red dates can be effectively cleaned. On the other hand, during the rotation of the second separation cylinder 5, the sorting process of red dates can be accelerated. Moreover, the telescopic rotating shafts 14 fixedly installed on the inner wall of the second separation cylinder 5 can drive a plurality of stirring rods 16 to rotate in the reverse direction through a linkage mechanism, further improving the sorting efficiency of red dates.

[0026] A telescopic rotating shaft 14 is fixedly connected to the axial center position inside the second separation cylinder 5. A hollow stirring rod 15 is rotatably connected to the axial center position inside the first separation cylinder 6. A linkage box 19 is provided inside the hollow stirring rod 15. A linkage mechanism capable of driving the hollow stirring rod 15 to reverse through the telescopic rotating shaft 14 is provided inside the linkage box 19. The linkage mechanism includes a short shaft rotatably connected to the inner wall of the linkage box 19. A first bevel gear 20 is fixedly connected to the end of the short shaft. A hollow rotating shaft 22 is rotatably connected to the inner wall of the hollow stirring rod 15. Both the hollow rotating shaft 22 and the telescopic rotating shaft 14 penetrate through the linkage box 19 and are rotatably connected thereto. Second bevel gears 21 are fixedly connected to the ends of both the hollow rotating shaft 22 and the telescopic rotating shaft 14. Both of the two second bevel gears 21 are located inside the linkage box 19 and are respectively meshed with the first bevel gear 20. A fixed rod 23 is fixedly connected to the side wall of the linkage box 19. The fixed rod 23 penetrates through the hollow stirring rod 15 and is fixedly connected to the inner wall of the first separation cylinder 6. A plurality of stirring rods 16 are fixedly connected to the hollow stirring rod 15. The left side of the hollow stirring rod 15 is in a closed state, and the left side of the hollow stirring rod 15 is rotatably connected to the first separation cylinder 6. The inner diameter of the part of the hollow stirring rod 15 on the left side where the linkage box 19 is placed is larger. The stirring rods 16 are evenly distributed in a circular state on the hollow stirring rod 15. The stirring rods 16 are made of soft materials, and a plurality of stirring rods 16 respectively correspond to a plurality of first discharge ports 18. The length of the stirring rods 16 is less than the inner diameter of the second separation cylinder 5. During the rotation of the stirring rods 16, the red dates larger than their gaps staying at the second discharge port 17 and the first discharge ports 18 can be toggled, thereby realizing the rate of red date sorting. Moreover, the rotation rates of the first separation cylinder 6 and the second separation cylinder 5 themselves are relatively slow and will not damage the red dates. The left and right in the text are for reference. Figure 1 。

[0027] Discharge ports are opened on both sides of the cleaning box 1. A drain plate 8 placed obliquely is provided outside the discharge ports. A plurality of drain strips are opened on the drain plate 8. A drying plate 9 is fixedly connected to the end of the drain plate 8. A plurality of drying ports are opened on the drying plate 9. The plurality of drain strips are parallel to the discharge ports and have a small width, which can allow the red dates to pass through normally. The water overflowing from the discharge ports flows into the water tank 7 through the drain strips, thereby realizing the circulation of water. A plurality of drying ports are communicated with a drying pipe, and the end of the drying pipe is communicated with a blower. During the process of the red dates rolling down, the red dates can be preliminarily dried. The collection box for collecting the red dates is placed at the end of the drying plate 9 to realize the rapid collection of the red dates.

[0028] A water tank 7 is provided below the draining plate 8. A circulation mechanism for driving the water circulation is provided between the water tank 7 and the cleaning tank 1. The circulation mechanism includes a connecting pipe 13 communicating between the two water tanks 7. The connecting pipe 13 and the cleaning tank 1 are communicated through a pump water pipe 24. A water pump is provided in the pump water pipe 24. The water pump can continuously pump the water in the two water tanks 7 into the cleaning tank 1. When the internal water in the cleaning tank 1 is full, the first separation cylinder 6 can be submerged. The red dates in the second separation cylinder 5 are all concentrated above the inside of the second separation cylinder 5 under the action of buoyancy. The red dates that meet the size can float to the water surface through the gaps, and under the action of the water flow, pass through the two discharge ports, roll onto the draining plate 8 and the air-drying plate 9, and finally enter the collection box to be collected. After the collection of the red dates with a smaller diameter is completed, the threaded rod 12 is adjusted to make the red dates with a larger diameter float to the water surface for sorting, so as to realize the sorting of the red dates during the process of cleaning the red dates.

[0029] During the use of the present invention, the red dates to be cleaned and sorted are placed into the second separation cylinder 5 through the feeding port 10. After the red dates are put in, the feeding port 10 is blocked by a baffle. The position of the first separation cylinder 6 is changed by rotating the threaded rod 12, the second separation cylinder 5 and the first separation cylinder 6 are staggered, the position between the second discharge port 17 and the first discharge port 18 is changed, the size of the gap therebetween is controlled, and water is continuously injected into the cleaning tank 1 through the water pump to submerge the first separation cylinder 6.

[0030] The motor 2 is started, the driving shaft 3 is driven to rotate by the motor 2, and then the rotation of the second separation cylinder 5 is realized. The second separation cylinder 5 can drive the linkage box 19 to rotate in the opposite direction through the telescopic rotating shaft 14, the second bevel gear 21 and the first bevel gear 20, and then the multiple stirring rods 16 can rotate in the opposite direction to the second separation cylinder 5 inside it to realize the cleaning of the red dates inside.

[0031] After the cleaning is completed, the threaded rod 12 is rotated to change the size of the gap therebetween, so that the red dates with a smaller diameter that meet the requirements float to the water surface, and water is continuously injected into the cleaning tank 1. The red dates can flow out through the discharge ports at both ends and roll onto the draining plate 8, and pass through the air-drying plate 9, and finally fall into the collection box to be collected. After the collection of the red dates with a smaller diameter is completed, the threaded rod 12 is gradually rotated to enlarge the diameter, so as to realize the collection of the red dates with a larger diameter, and thus realize the grading and sorting of the red dates.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
