Technical Field
[0001] The utility model relates to the technical field of red date screening, in particular to a red date sorting device based on machine vision. Background Art
[0002] Jujube is one of the important economic fruit trees in my country, with high edible and medicinal value. In recent years, with the development of the jujube industry, the output of jujube has been increasing, and the demand for jujube sorting has also been increasing.
[0003] Visual technology can be used to intelligently grade red dates. After the red dates are marked with grades on the conveyor rollers and conveyed to the corresponding discharge port, the red dates are pushed into the corresponding discharge channel by the discharge device to achieve grading. After the red dates are discharged from the discharge channel, a receiving box is usually placed at the discharge port to collect the red dates of different grades. However, when the receiving box is full, it needs to be replaced manually, which increases the labor intensity of the workers; and it is impossible to count the number of red dates of different grades, which brings inconvenience to the sales and management of red dates. Utility Model Content
[0004] The utility model aims to provide a red date sorting device based on machine vision, which has the effect of automatically changing boxes and reducing the labor intensity of workers.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a red date sorting device based on machine vision, including a red date screening machine and a receiving box, the red date screening machine is provided with a plurality of discharge channels, and the discharge ports of the plurality of discharge channels are respectively provided with a placement seat, a discharge conveying mechanism is provided on one side of the placement seat, and a feeding conveying mechanism is provided on the other side of the placement seat, a lifting platform is provided between the placement seat and the feeding conveying mechanism, and a box pushing mechanism for transporting the receiving box to the side of the discharge conveying mechanism is provided under the placement seat and the lifting platform.
[0006] By adopting the above technical scheme, after the red dates pass through the AI intelligent image screening of the red dates screening machine, they are discharged from the corresponding discharging channels according to different grades. A placing seat is provided at the discharging channel, and the placing seat is used to place a receiving box. A feeding conveying mechanism is provided on one side of the placing seat, and a discharging conveying mechanism is provided on the other opposite side. A lifting platform is provided between the placing seat and the feeding conveying mechanism. After the receiving box is transported from the feeding conveying mechanism to the lifting platform, the lifting platform rises to lift a receiving box. After the lifting platform rises, it blocks the receiving box on the feeding conveying mechanism, and the box pushing mechanism pushes the receiving box from the lifting platform to the placing seat. The red dates screened by the red dates screening machine fall into the receiving box on the placing seat, the lifting platform descends, and the receiving box on the feeding conveying mechanism is transported to the lifting platform, the lifting platform rises, and the box pushing mechanism is reset. When the red dates in the receiving box are full, the box pushing mechanism pushes the receiving box on the placing seat to the discharging conveying mechanism, and at the same time pushes the receiving box on the lifting platform to the placing seat, thereby completing the automatic box replacement of the receiving box and reducing the labor intensity of the workers.
[0007] The utility model is further configured as follows: an electronic scale or a weight sensor is fixedly mounted on the placement seat, and the upper end surface of the electronic scale or the placement seat is in the same horizontal plane as the upper end surface of the discharging conveying mechanism.
[0008] By adopting the above technical solution, the electronic scale or weight sensor can detect the weight, and when the receiving box reaches the specified weight, the box pushing mechanism is driven to automatically change the box.
[0009] The utility model is further configured as follows: the height of the feeding conveying mechanism is smaller than that of the placing seat.
[0010] The utility model is further configured as follows: a first cylinder is provided below the lifting platform, and an output shaft of the first cylinder is fixedly connected to the lifting platform.
[0011] By adopting the above technical solution, the first cylinder drives the lifting platform to rise or fall. When the lifting platform descends, the upper end surface of the lifting platform is at the same level as the feed conveying mechanism, which is convenient for the empty receiving box to enter the lifting platform. When the lifting platform rises, the lifting platform and the discharge conveying mechanism are at the same level, which is convenient for transferring the receiving box on the lifting platform to the placement seat. At the same time, the rising lifting platform limits the receiving box on the feed conveying mechanism.
[0012] The utility model is further configured as follows: the widths of the placement seat and the lifting platform are smaller than the width of the material receiving box, and the box pushing mechanisms are provided on both sides of the placement seat.
[0013] By adopting the above technical solution, the width of the feed conveying mechanism, the placement seat and the lifting platform is smaller than the width of the material receiving box, and a box pushing mechanism is arranged on both sides of the placement seat and the lifting platform to facilitate the box pushing mechanism to transfer the material receiving box.
[0014] The utility model is further configured as follows: the box pushing mechanism includes a slide plate slidably connected between the feed conveyor mechanism and the discharge conveyor mechanism, and the slide plate is provided with two pushing pieces, the pushing piece close to the discharge conveyor mechanism pushes the receiving box from the placement seat to the discharge conveyor mechanism, and the pushing piece away from the discharge conveyor mechanism pushes the receiving box from the lifting platform to the placement seat.
[0015] The utility model is further configured as follows: the pusher comprises two mounting seats fixedly mounted on the slide plate, a rotating shaft is rotatably connected between the two mounting seats, a push rod and a support rod are fixedly mounted on the rotating shaft, and an angle between the push rod and the support rod is not less than 90 degrees.
[0016] The utility model is further configured as follows: the length of the support rod is greater than that of the push rod, and the upper end of the push rod is higher than the placement seat.
[0017] By adopting the above technical scheme, in the initial state, one pushing piece is located between the feed conveying mechanism and the lifting platform, and the other pushing piece is located between the lifting platform and the placing seat. Since the length of the support rod is greater than the length of the push rod, under the action of gravity, the support rod is at the bottom and the push rod is at the top. When the receiving box is full of red dates, the slide plate is driven to move toward one end of the discharging conveying mechanism, and the push rod pushes the receiving box to one end of the discharging conveying mechanism. After the pushing is completed, since the push rod and the support rod are fixedly mounted on the rotating shaft, the rotating shaft is rotated to connect the mounting seat, when the slide plate moves to one end of the feed conveying mechanism, the bottom of the receiving box contacts the push rod, causing the push rod and the support rod to rotate, and the push rod and the support rod pass through the bottom of the receiving box, waiting for the next round of transmission.
[0018] The utility model is further configured as follows: the feed conveying mechanism and the discharge conveying mechanism include a support frame and a belt or a conveying roller rotatably connected to the support frame.
[0019] By adopting the above technical solution, the material box can be transported by belts or conveyor rollers.
[0020] The utility model is further configured as follows: the slide plate is slidably connected to the support frame, a connecting plate is fixedly connected between the slide plates of the two groups of the box pushing mechanisms, a fixing plate is fixedly installed on the support frame, a second cylinder is fixedly installed on the fixing plate, an output shaft of the second cylinder is fixedly connected to the connecting plate, a guide rod is fixedly installed on one side of the connecting plate close to the fixing plate, and the guide rod is slidably connected to the fixing plate.
[0021] By adopting the above technical solution, the second cylinder can drive the connecting plate to move, so that the sliding rod can reciprocate along the supporting frame.
[0022] When the red dates in the receiving box are full, the box pushing mechanism pushes the receiving box on the placing seat to the discharging conveyor mechanism, and at the same time pushes the receiving box on the lifting platform to the placing seat, thereby completing the automatic box changing of the receiving box and reducing the labor intensity of the workers.

[0033] Working principle of this utility model:
[0034] After the red dates pass through the AI intelligent image screening of the red dates screening machine 1, they are discharged from the corresponding discharging channel 3 according to different grades. A placement seat 4 is provided at the discharging channel 3, and an electronic scale 5 is provided on the placement seat 4. In the initial state, one pushing piece 92 is located between the feeding conveying mechanism 7 and the lifting platform 8, and the other pushing piece 92 is located between the lifting platform 8 and the placement seat 4. Since the length of the support rod 924 is greater than the length of the push rod 923, under the action of gravity, the support rod 924 is at the bottom and the push rod 923 is at the top.
[0035] After the receiving box 2 is transported from the feeding conveying mechanism 7 to the lifting platform 8, the first cylinder 10 drives the lifting platform 8 to rise and lifts a receiving box 2. After the lifting platform 8 rises, it blocks the receiving box 2 on the feeding conveying mechanism 7, starts the second cylinder 95, drives the slide plate 91 to move toward one end of the discharging conveying mechanism 6, and the push rod 923 close to the side of the feeding conveying mechanism 7 pushes the receiving box 2 from the lifting platform 8 to the electronic scale 5.
