DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0018] Embodiment 1 See attached Figure 1-4, a fully automatic device for sorting and storing good and bad seedlings during seedling selection, used for cooperating with a PLC controller to realize seedling sorting, characterized in that: it comprises a working support 1 and a transmission component 2 arranged on the working support 1, a detachable seedling box 4 is placed on the transmission component 2, the working support 1 is provided with an image acquisition area 7 and a baffle plate 14, the working support 1 is respectively provided with an inferior seedling area and two groups of superior seedling areas, and position sensors are provided at the inferior seedling area and the superior seedling area; A poor seedling sorting device 6 is arranged between the working support 1 and the poor seedling area to realize the sorting of the poor seedlings. A sorting mechanism 3 is arranged between the two groups of the good seedling areas. The sorting mechanism 3 includes a driving component and a sorting adjustment device 35 arranged at the bottom of the driving component. The sorting adjustment device 35 is correspondingly connected to the good seedling sorting plates 37 through multiple groups of connecting rods 38. The multiple groups of the good seedling sorting plates 37 are slidably connected through limit rods 371. One end of the multiple groups of the good seedling sorting plates 37 is provided with a material sorting device 39 that cooperates with the baffle plate 14 to realize batch sorting and sorting of the good seedlings. The sorting mechanism 3 and the poor seedling sorting device 6 are both provided with visual sensors. The PLC controller is respectively connected to the transmission component 2, the image acquisition area 7, the baffle plate 14, the position sensor, the poor seedling sorting device 6, the sorting mechanism 3 and the visual sensor by telecommunication.

[0019] Place the seedling box 4 on the conveying component 2, pull out the bottom plate at the bottom of the seedling box 4, place the seedlings on the conveying component 2, take the seedling box 4 away from the conveying component 2, control the conveying component 2 to move through the PLC controller, move the seedlings to the image acquisition area 7 for image acquisition, and transmit the acquired images to the PLC controller, analyze and process the acquired images through the PLC controller, judge the quality of the seedlings according to the thickness of their roots, and transmit the quality signals to the sorting mechanism 3 and the inferior seedling sorting device 6 respectively. When the conveying component 2 conveys the seedlings to the bottom of the inferior seedling sorting device 6, the position sensor transmits the detection information to the PLC controller, and the PLC controller controls the conveying component 2 to move the seedlings to the image acquisition area 7 for image acquisition. The acquired images are transmitted to the PLC controller, and the acquired images are analyzed and processed by the PLC controller. The quality of the seedlings is judged according to the thickness of their roots, and the quality signals are transmitted to the sorting mechanism 3 and the inferior seedling sorting device 6 respectively. When the conveying component 2 conveys the seedlings to the bottom of the inferior seedling sorting device 6, the position sensor transmits the detection information to the PLC controller, and the PLC controller controls the conveying component 2 to move the seedlings to the bottom of the inferior seedling sorting device 6. Component 2 stops, and at the same time, the inferior seedlings are sorted out according to the collected image information through the visual sensor and the inferior seedling sorting device 6, and are sorted and sorted into the inferior seedling area in sequence. When the inferior seedlings in the group of seedlings are sorted out, the conveying component 2 is started. When the superior seedlings are conveyed to the bottom of the sorting mechanism 3, the position sensor transmits the detection information to the PLC controller. According to the cooperation of the visual sensor and the sorting mechanism 3, the superior seedlings are sorted and uniformly sorted into the superior seedling area in combination with the collected image information, thereby realizing the effective sorting of superior and inferior seedlings, avoiding the planting of inferior seedlings, affecting the later growth quality and survival rate, thereby occupying land resources, and artificial filling in the later stage also requires a lot of manpower and financial resources; Through the cooperation of the sorting mechanism 3 and the material organizing mechanism 39 with the material blocking plate 14, the material blocking plate 14 can effectively block the movement of the superior seedlings, so that the superior seedlings can be automatically integrated to one side of the material blocking plate 14 in turn, and the integrated superior seedlings are sorted into superior seedling areas in batches through the material organizing mechanism 39, the sorting adjustment device 35 and the superior seedling sorting plate 37, thereby improving the efficiency of superior seedling sorting and integration, and can centrally integrate and sort the superior seedlings after the inferior seedlings are sorted, thereby ensuring the quality and survival rate of subsequent seedlings.

[0020] See attached Figure 4 In order to realize the centralized sorting of the integrated superior seedlings into the superior seedling area, as a possible implementation mode of this scheme, preferably, the driving component includes a second screw rod 31 arranged on the support frame 13, and a sliding seat 32 is slidably connected to the second screw rod 31, and electric push rods 33 are arranged on both sides of the sliding seat 32, and the movable end of the electric push rod 33 is connected to a mounting plate 34, and the sorting adjustment device 35 is arranged at the bottom of the mounting plate 34.

[0021] The PLC controller controls the motor to drive the second screw rod 31 to rotate, and the cooperation between the second screw rod 31 and the sliding seat 32 makes the sliding seat 32 move to the top of the superior seedlings, and the electric push rod 33 is used to drive the sorting adjustment device 35 and the superior seedling sorting plate 37 to move downward. The PLC controller controls the sorting adjustment device 35 to adjust the distance between the superior seedling sorting plates 37 to adapt to the position of the superior seedlings, so as to centrally clamp the superior seedlings, and sort the clamped superior seedlings into the superior seedling area. The second screw rod 31 cooperates with the movement of the sliding seat 32 and the mounting plate 34 to realize unified sorting of the superior seedlings, instead of sorting the superior seedlings one by one, thereby improving the sorting efficiency.

[0022] Embodiment 2 See attached Figure 4-5 and attached Fig.12 In order to achieve the purpose of integrating and centrally sorting superior seedlings and improve the sorting efficiency, as a possible implementation method of this scheme, preferably, the material sorting device 39 includes a material sorting rod 391 slidably connected to the superior seedling sorting plate 37 and the limiting rod 371, and a material sorting plate 392 and a movable plate 393 are respectively provided at both ends of the material sorting rod 391. A tension spring 394 is provided between the movable plate 393 and the superior seedling sorting plate 37, and a material sorting groove 372 adapted to the material sorting plate 392 is provided at the bottom of the superior seedling sorting plate 37 and the limiting rod 371.

[0024] When the baffle plate 14 blocks several groups of superior seedlings to one side, the PLC controller controls the conveying component 2 to stop working. At the same time, the PLC controller controls the sorting adjustment device 35 to adjust the spacing of the superior seedling sorting plate 37 to a suitable position. The electric push rod 33 drives the superior seedling sorting plate 37 and the whole material plate 392 to move downward. During the downward movement of the whole material plate 392, the superior seedlings on the transmission component 2 will be separated, so that the number of superior seedlings is matched with the space formed between the superior seedling sorting plate 37 and the limit rod 371, thereby partially integrating multiple groups of superior seedlings, so that the superior seedling sorting plate 37 can uniformly sort the superior seedlings into the sorting slots on the sorting tray 8, and through the cooperation of the second screw rod 31, the sliding seat 32, the cylinder 33, etc. Multiple groups of superior seedlings are sorted into the sorting slots on the sorting tray 8 in turn, which not only realizes the sorting of superior and inferior seedlings, but also improves the efficiency of sorting, ensuring the survival rate and quality of seedlings in the later stage; when the whole material plate 392 contacts the surface of the conveying component 2 during the downward movement, while the electric push rod 33 drives the superior seedling sorting plate 37 to continue to move downward, the whole material plate 392 pushes the moving plate 393 upward through the whole material rod 391, and at this time the tension spring 394 is stretched by the tension. After the whole material plate 392 separates and integrates the superior seedlings, when the electric push rod 33 moves upward to the left and right, the whole material plate 392 is reset under the action of the tension spring 394, and cooperates with the superior seedling sorting plate 37 to realize batch integration of the superior seedlings, thereby realizing unified sorting of the superior seedlings.

A rack 354 meshing with the driving gear 352 is provided on one side, and U-shaped frames 36 are provided on both sides of the driving motor 351 relative to the fixing rod 356.

[0026] The PLC controller controls the operation of the driving motor 351, driving the driving gear 352 to rotate. Since the racks 354 on both sides are meshed with the driving gear 352, the connecting frames 353 on both sides are controlled to move in a direction away from or close to each other, and the distance between the multiple groups of seedling sorting plates 37 connected by the connecting rod 38 is adjusted, so that the seedlings can be better clamped from both sides and sorted into the seedling area. During the adjustment process, the two groups of connecting frames 353 drive the slide 355 to slide along the slider 357 at the bottom of the fixed rod 356. With the cooperation of the slider 357 and the slide 355, the adjustment direction of the two groups of connecting frames 353 is limited, thereby adjusting the distance between the multiple groups of seedling sorting plates 37 to adapt to the clamping of seedlings. It has a wide range of applications, is simple to operate, and is easy to implement.

In cooperation with the visual sensor, the position of the clamping plate 67 is adjusted through the displacement adjustment component 5, so that the two groups of clamping plates 67 are placed on both sides of the inferior seedlings. The PLC controller controls the motor connected to the rotating shaft 62 to rotate, so that the rotating shaft 62 drives the two groups of meshing matching gears 63 to rotate, and at the same time, the matching gears 63 mesh with the teeth on the support 64, driving the two groups of supports 64 to rotate, so that the two groups of clamping plates 67 fixedly connected to the support 64 through the fixing plate 66 are close to each other, thereby sorting out the inferior seedlings, and sorting multiple groups of inferior seedlings into the inferior seedling tray 15 on the groove 12 in turn through the displacement adjustment component 5, so as to realize the sorting operation of the inferior seedlings, so as to facilitate the subsequent integration and sorting of the superior seedlings, improve the sorting efficiency of the superior and inferior seedlings, and ensure the survival rate and quality of the superior seedlings.
