Description

[0002] The quality of strawberry seedlings is a key link that directly determines its yield and quality, and the early or late differentiation of flower buds is an important indicator to measure the quality of strawberry seedlings, which directly determines the early listing and early income. Therefore, strawberry seedling growers mainly promote the differentiation of strawberry flower buds through physical and chemical control methods such as low night temperature treatment, shortened daylight length, and controlled nitrogen fertilizer, and determine whether it is differentiated through traditional stereoscopic dissection microscope observation. This observation method not only requires careful standard operation of peeling the stem tip to avoid damage and affect the observation effect, but also has very high identification experience and technical requirements for accurately judging the differentiation morphology.

[0034] The rice seedling stem tip morphology detection mechanism, the driving unit, and the rice seedling differentiation and collection mechanism are electrically connected to the PC terminal.

[0035] Furthermore, two opposite inner side walls of the detection box 2 are respectively fixedly connected with support plates 14 , the bottom end of the conveying chain 9 is in sliding contact with the top end of the support plate 14 , and a gap is left between the two support plates 14 for the strawberry seedlings to pass through.

[0036] The seedling clamping mechanism can clamp individual strawberry seedlings and transport the clamped seedlings to the detection box 2. The strawberry seedlings are detected by the seedling stem tip morphology detection mechanism set in the detection box 2, so as to obtain the degree of flower bud differentiation of the strawberry seedling stem tip. The seedling distinguishing and collecting mechanism can distinguish the strawberry seedlings after the detection, distinguish the seedlings with flower bud differentiation from the seedlings without flower bud differentiation and collect them, and cultivate the distinguished seedlings differently, so as to speed up the fruiting speed of the seedlings and increase the income of the farmers.

[0040] When the strawberry seedlings are transported to the middle position inside the detection box 2, the PC end controls the two second electrically-controlled telescopic rods 23 to extend at the same time, driving the pressure ring 24 to move downward until the mature leaves of the strawberry seedlings are pressed down to unfold outward, thereby exposing the stem tip of the seedlings. Then the PC end controls the first electrically-controlled telescopic rod 22 to extend, so that the U-shaped frame 26 descends to the position of the stem tip of the seedlings.

[0042] The operator loads the strawberry seedlings at the loading end of the conveyor chain 9. When the two corresponding clamping blocks 10 on the two conveyor chains 9 move to the same position, the operator places the single seedling between the two clamping blocks 10, clamps the single seedling through the two clamping blocks 10, and then the conveyor chain 9 continues to convey and transports the clamped single seedling to the bottom of the U-shaped frame 26 for perspective inspection.

[0043] According to a further optimized solution, an arc-shaped rubber block 13 is fixedly connected in the seedling clamping groove.

After the strawberry seedlings with flower bud differentiation fall on the seedling separation funnel 16, they slide into the second collecting box 19 under the guidance of the toggle plate 17 and are collected. When the X-ray transmitting head 27 detects the strawberry seedlings without flower bud differentiation, the second motor 20 works to drive the toggle plate 17 to rotate, so that the free end of the toggle plate 17 rotates to a position close to the second collecting box 19. After the strawberry seedlings with flower bud differentiation fall on the seedling separation funnel 16, they slide into the first collecting box 18 under the guidance of the toggle plate 17 and are collected. In this way, the distinguishing and collecting work of the seedlings with flower bud differentiation and the seedlings without flower bud differentiation is completed.

[0050] Embodiment 2:

[0051] Reference Figure 8 As shown, the difference between this embodiment and the first embodiment is that the outer wall of the pressure ring 24 is fixedly connected to the limiting frame 29, and the height of the bottom end of the limiting frame 29 is lower than the height of the bottom end of the pressure ring 24. When the limiting frame 29 drops to the lowest position, its bottom end contacts the bottom end of the support plate 14. At this time, there is a gap between the bottom end of the pressure ring 24 and the top end of the clamping block 10. This embodiment can prevent the pressure ring 24 from dropping too low and contacting the top end of the clamping block 10, causing squeezing damage to the mature leaves of the strawberry seedlings, thereby effectively improving the integrity of the strawberry seedlings after detection.
