Description

Technical Field

[0001] The invention relates to the technical field of red date sorting and processing equipment, and in particular to a red date sorting device. Background Art

[0002] After the red dates are picked, they need to be sorted according to their size, quality, color and other characteristics to ensure that each grade of red dates meets the corresponding standards, thereby improving the overall quality of the product. At present, red dates are usually sorted manually, which is not only time-consuming and labor-intensive, but also inefficient, and in the process of manual sorting, it will also cause secondary damage to the red dates.

[0003] In view of the above technical problems, the Chinese utility model patent with the authorization announcement number CN211637357U discloses a red date sorting machine, including a chassis, a loading device, a feeding device, an image acquisition device and a feeding device. The loading device includes a silo, a climbing conveyor belt and a linear double-channel vibrating plate. The climbing conveyor belt is connected to the silo and the linear double-channel vibrating plate. The feeding device includes a feeding conveyor belt arranged on the top of the chassis, and the linear double-channel vibrating plate is connected to the input end of the feeding conveyor belt. A group of image acquisition devices and a group of feeding devices are sequentially arranged along the conveying direction on the feeding conveyor belt. The image acquisition device has multiple cameras. The feeding device includes a feeding channel and a feeding solenoid valve respectively arranged on both sides of the feeding conveyor belt. The inside of the feeding channel is divided into multiple independent grading channels, and the number of the feeding solenoid valves is the same as the number of the grading channels. The sorting device can automatically screen the red dates according to the size or defects, reduce labor costs, and has high screening efficiency.

[0004] However, when the grading channels of the above-mentioned red dates sorting machine are outputting red dates, it is necessary to manually place red dates collection boxes at the exits of each grading channel for temporarily collecting the red dates. The red dates collection boxes not only occupy most of the space on both sides of the sorting machine, but also because the collection progress of each red date collection box is different, there is a very high probability that multiple red dates collection boxes are filled at the same time or the filling interval is short. Therefore, the staff is required to monitor the multiple red dates collection boxes at all times and replace the red dates collection boxes continuously and quickly, which leads to heavy work tasks and high labor intensity in manually placing the red dates collection boxes.

[0021] The beneficial effect of the present invention is as follows: by adopting the red date sorting device, when it is necessary to sort the red dates, firstly, the red dates are input into the double-channel sorting trough in cooperation with the red date lifting device, and then the red dates are guided by the double-channel sorting trough and divided into two batches and fall onto the two red date conveying lines respectively, and then the red date conveying line carries the red dates through the bottom of the intelligent shooting device, so that the intelligent shooting device obtains the image information of the red dates, and at the same time cooperates with the image recognition control system to analyze and identify the size, quality, color and other characteristics of the red dates, and controls the corresponding high-pressure jet head to perform jetting work at a certain time according to the recognition characteristics; thereafter, when the red date conveying line transports the red dates to the designated high-pressure jet head position, the high-pressure jet head will immediately spray, blow the red dates down the red date conveying line, and enter the designated classification box through the feed inlet;

[0022] At the same time, if the red dates are of good quality, after entering the designated classification box, they will be collected into the corresponding red date collection box through the discharging hopper; if the red dates have no recognized features or have problems such as missed shots or multiple shots, after entering the designated classification box, they will fall into the red date return frame through the discharging hopper, and pass through the opening at the bottom of the red date return frame and the turning plate 1, and directly slide onto the conveyor belt. Since the conveying direction of the conveyor belt is facing away from the roller conveyor at this time, the conveyor belt can transport the red dates back to the lifting equipment of the red dates or the designated return box for sorting again;

[0023] Then, if the weight sensor inside the flip plate 2 senses that the weight of the red dates in the red date collection frame reaches a certain standard, the flip component 1 will control the flip plate 1 to flip and close the opening at the bottom of the red date return frame, so that the red dates that need to be returned are temporarily stored in the red date return box; the flip component 2 controls the flip plate 2 to flip and open the opening at the bottom of the red date collection frame, releasing the red dates inside onto the conveyor belt; the servo motor drives the belt roller to rotate in the reverse direction, so that the conveyor belt conveys the red dates in the direction of the roller conveyor; the rolling conveyor conveys the red date packaging box to one end of the conveyor belt in advance, waiting to be connected to the red dates output by the conveyor belt;

[0024] Finally, after all the red dates in the red date collection frame are transferred to the red date packaging box, the flip component 1, flip component 2 and the servo motor will automatically resume their previous working state to continue the subsequent red date sorting task. At the same time, the rolling conveyor will transport the empty red date packaging box to one end of the conveyor belt in advance to wait for the next output of red dates.

[0025] The above-mentioned red dates collection frame and red dates return frame not only realize the effect of automatically collecting various types of red dates, but also cooperate with the flip plate one and flip plate two that can be flipped, the conveyor belt for conveying red dates and other structures to realize the automatic packaging and automatic return of red dates. Therefore, while replacing the traditional manual placement and replacement of red dates collection boxes to collect red dates, it also definitely improves the sorting efficiency of red dates.

The sprocket two 642 and the crank handle 644 are respectively fixedly connected to the rotating shaft three 631 on both sides of the movable guide plate 63.

[0046] By adopting the above-mentioned red date diversion mechanism 6, when the flip assembly 44 drives the flip plate 43 to close the bottom opening of the red date return frame 41, the rotating shaft 441 will first drive the sprocket 641 to rotate, and then the sprocket 641 drives the rotating shaft 3 631 to rotate through the chain 643 and the sprocket 2 642, and then the rotating shaft 3 631 drives the active guide plate 63 connected thereto to flip and the crank 644 to rotate. Since the other ends of all the cranks 644 are hinged to the synchronous long rod 645, and each crank 644 is respectively fixedly connected to the rotating shaft 3 631 on one side of each active guide plate 63, when a crank 644 rotates, the synchronous long rod 645 will drive all the cranks 644 to rotate together, and at the same time, drive the active guide plates 63 connected to each rotating shaft 3 631. The plate 63 flips synchronously; then, when the movable end of the movable guide plate 63 located at the opening of the red date collection frame 42 flips to above the rotating shaft three 631, and the movable end of the movable guide plate 63 located above the fixed guide plate 62 flips to below the rotating shaft three 631, all the red dates falling out of the outlet of the hopper 35 above the red date collection frame 42 will be guided by the movable guide plate 63 and the fixed guide plate 62, and slide into the red date guide groove 61 through the gap two 612; finally, since the bottom of the red date guide groove 61 is inclined, and the lowest point and the highest point of the bottom of the red date guide groove 61 are respectively located on the side of the red date return frame 41 and the red date collection frame 42 arranged at the head and tail, all the red dates will pass through the red date guide groove 61 and the gap one 611, and all flow into the red date return frame 41.

[0047] Furthermore, this method can prevent new red dates from falling into a red date collection frame 42 during the process of releasing and transferring red dates, causing the red dates transferred by the red date collection frame 42 to be overweight. At the same time, it can also prevent other red date collection frames 42 from reaching the standard weight before the above process is completed, thereby causing overweight again or two or more red date collection frames 42 to release red dates at the same time.

[0048] like Figure 4 , Figure 5 As shown, the upper end of the fixed guide plate 62 is fixedly connected with a vertical baffle plate 1 621, and the two sides of the baffle plate 1 621 are respectively fixedly connected to the side walls of the red date collection frame 42 or the red date return frame 41, and the top of the red date collection frame 42 is fixedly provided with a vertical baffle plate 2 422, and the baffle plate 2 422 blocks the front of the movable guide plate 63 in the direction of leading the red dates into the red date collection frame 42, and the upper side of the movable guide plate 63 is vertically connected with a pair of baffle plates 3 632, and the two baffle plates 3 632 are respectively flush with the two sides of the movable guide plate 63. By using the above-mentioned baffle plate 1 621, baffle plate 2 422 and baffle plate 3 632, it can effectively ensure that the red dates slide safely into the red date collection frame 42 or the red date guide groove 61 according to the established route.

[0049] like Figure 2 As shown, rubber baffles 511 are fixedly arranged on the inner walls of both sides of the U-shaped plate 51. The rubber baffles 511 are in an arc shape, and one end is fixedly connected to the inner wall of the side of the U-shaped plate 51, and the other end is parallel and close to the upper surface of the conveyor belt 53. By adopting the above-mentioned rubber baffles 511, it is possible to effectively prevent the red dates from getting stuck in the gap between the conveyor belt 53 and the inner wall of the side plate of the U-shaped plate 51, thereby ensuring the transportation safety of the red dates.

[0050] like Figure 3 As shown, a Y-shaped plate 331 is fixedly arranged inside the classification box 33, and two feeding ports 34 on the classification box 33 are respectively located on both sides of the Y-shaped plate 331. By adopting the above-mentioned Y-shaped plate 331, not only can the red dates be prevented from passing through the feeding ports 34 on both sides of the classification box 33 at the same time, resulting in falling out of the classification box 33, but also the red dates flying out of the two red date conveying lines 32 can be prevented from colliding with each other, causing secondary damage to the red dates.

[0051] like Figure 2 , Figure 3 As shown, a box cover 311 is slidably provided on the top of the support box 31, and the box cover 311 and the dual-channel material distribution trough 37 can jointly close the opening on the top of the support box 31. By adopting the above-mentioned box cover 311, not only can dust be effectively blocked from entering, but also the working safety of the red date conveying line 32 can be guaranteed.

[0052] like Figure 4 , Figure 5 As shown, rollers 451 are rotatably provided on both sides of the flip plate 1 43 and the flip plate 2 45 to roll and contact the surface of the conveyor belt 53. By adopting the above rollers 451, when the flip plate 1 43 and the flip plate 2 45 flip downward, the rolling can ensure that the lower ends of the flip plate 1 43 and the flip plate 2 45 safely contact the surface of the conveyor belt 53, and then open a sufficient opening at the bottom of the red date collection frame 42 or the red date return frame 41 to ensure that the red dates flow out quickly.

[0053] The working principle of this embodiment:

[0054] When it is necessary to sort the red dates, firstly, the lifting device for the red dates is used to input the red dates into the dual-channel sorting trough 37. Then, under the guidance of the dual-channel sorting trough 37, the red dates are divided into two batches and fall onto the two red date conveying lines 32 respectively. Then, the red date conveying line 32 carries the red dates through the bottom of the intelligent photographing device 36, so that the intelligent photographing device 36 obtains the image information of the red dates. At the same time, the image recognition control system is used to analyze and identify the size, quality, color and other characteristics of the red dates, and the corresponding high-pressure jet head 38 is controlled to perform jetting at a certain time according to the identified characteristics. After that, when the red date conveying line 32 transports the red dates to the designated high-pressure jet head 38 position, the high-pressure jet head 38 will immediately spray, blow the red dates down the red date conveying line 32, and enter the designated classification box 33 through the feed port 34.

[0055] At the same time, if the red dates are of good quality, after entering the designated classification box 33, they will be collected into the corresponding red date collection frame 42 through the discharge hopper 35; if the red dates have no recognized features or have problems such as missed shots or multiple shots, after entering the designated classification box 33, they will fall into the red date return frame 41 through the discharge hopper 35, and pass through the opening at the bottom of the red date return frame 41 and the turning plate 43, and directly slide onto the conveyor belt 53. Since the conveying direction of the conveyor belt 53 is facing away from the roller conveyor 2 at this time, the conveyor belt 53 can convey the red dates back to the lifting device of the red dates or the designated return box for sorting again;

[0056] Then, if the weight sensor inside the flip plate 45 senses that the weight of the red dates in the red date collection frame 42 reaches a certain standard, the flip component 44 will control the flip plate 43 to flip and close the opening at the bottom of the red date return frame 41, so that the red dates that need to be returned are temporarily stored in the red date return box; the flip component 46 controls the flip plate 45 to flip and open the opening at the bottom of the red date collection frame 42, and release the red dates inside onto the conveyor belt 53; the servo motor 54 drives the belt roller 52 to rotate in the reverse direction, so that the conveyor belt 53 conveys the red dates in the direction of the roller conveyor 2; the rolling conveyor conveys the red date packaging box to one end of the conveyor belt 53 in advance, waiting to receive the red dates output by the conveyor belt 53;

[0057] Finally, after all the red dates in the red date collection frame 42 are transferred to the red date packaging box, the flip component 1 44, the flip component 2 46 and the servo motor 54 will automatically resume their previous working state to continue the subsequent red date sorting task. At the same time, the rolling conveyor will transport the empty red date packaging box to one end of the conveyor belt 53 in advance to wait for the next output of red dates.

[0058] The red dates collection frame 42 and the red dates return frame 41 not only realize the effect of automatically collecting various types of red dates, but also cooperate with the reversible flip plate 1 43 and flip plate 2 45 and the conveyor belt 53 for conveying red dates to realize the automatic packaging and automatic return of red dates. Therefore, while replacing the traditional manual placement and replacement of red dates collection boxes to collect red dates, it also greatly improves the red dates sorting efficiency.
