DETAILED DESCRIPTION

[0017] The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0018] like Figure 1-Figure 3As shown in the figure, an embodiment of the present invention is proposed, which provides a seedling raising rack for virus-free strawberry tissue culture seedlings, which is used to solve the problem that the light intensity in the existing seedling raising process is fixed and cannot adapt to the growth requirements of strawberries. The rack comprises: a frame 1; an irradiation lamp 2, which is slidably mounted on the frame 1; a rotating shaft 3, which is rotatably connected to the frame 1, and the frame 1 is equipped with a motor 4 through a mounting frame, and the output end of the motor 4 is fixedly connected to the rotating shaft 3; a rotating frame 5, which is fixedly connected to the rotating shaft 3; seedling raising boxes 6 arranged at intervals, which are rotatably connected to eccentric positions at different positions on the rotating frame 5; an adjusting mechanism, which is arranged on the frame 1, and is used to change the distance between the irradiation lamp 2 and the seedling raising box 6 to meet the requirements of crop growth. Different requirements for light intensity in different growth periods; a demoulding mechanism, arranged in the seedling box 6, for enclosing and demoulding the object; a shading mechanism, arranged in the frame 1, for changing the light exposure time of the object, the frame 1 is fixedly connected with a ring gear 701; a first gear 702, fixedly connected to the seedling box 6, the first gear 702 is meshed with the ring gear 701; the adjustment mechanism includes: a second gear 801, rotatably connected to the frame 1; a rack 802, slidably connected to the frame 1, the rack 802 is fixedly connected to the irradiation lamp 2; a one-way gear 803, installed on the rotating shaft 3, the rack 802 and the one-way gear 803 are both meshed with the second gear 801.

[0019] In the above scheme, the light emitted by the irradiation lamp 2 is simulated light, which is used to simulate the lighting in the real environment, thereby improving the strawberry seedling effect. The motor 4 is a servo motor, which is used to control the rotation direction and rotation speed of the rotating shaft 3. In the process of raising strawberry seedlings, the output shaft of the motor 4 drives the rotating shaft 3 to rotate counterclockwise (left viewing direction), and the rotating shaft 3 drives the rotating frame 5 to rotate counterclockwise together, and the rotating frame 5 drives the seedling box 6 to rotate counterclockwise together. The seedling box 6 drives the first gear 702 to rotate counterclockwise (revolution), and the first gear 702 begins to roll along the gear ring 701 (clockwise rotation), so as to ensure that the seedling box 6 remains horizontal during the movement. During the process, the irradiation lamp 2 remains on, and the distance between the seedling box 6 and the irradiation lamp 2 is changed by the rotating rotating frame 5, thereby changing the light intensity applied to the strawberry seedlings, so as to model the change of light intensity in the real environment, thereby improving the quality of strawberry seedlings.

[0020] During the counterclockwise rotation of the rotating shaft 3, the rotating shaft 3 drives the one-way gear 803 to rotate counterclockwise, and the one-way gear 803 drives the second gear 801 to rotate clockwise. The second gear 801 drives the rack 802 to move downward, and the rack 802 slides relatively with the frame 1. The rack 802 drives the irradiation lamp 2 to move downward together, thereby changing the distance between the irradiation lamp 2 and the seedling box 6, thereby changing the intensity of light received by the strawberry seedlings, so that the light intensity during the seedling cultivation process is always matched with the growth of the strawberry seedlings, and preventing the strawberry seedlings from being exposed to too high or too low light intensity that affects the normal cultivation of the strawberry seedlings. After the seedling cultivation is completed, the irradiation lamp 2 is pulled upward, and the irradiation lamp 2 drives the rack 802 to move upward together, and the rack 802 drives the one-way gear 803 to start rotating clockwise through the second gear 801. At this time, the one-way gear 803 idles (that is, the rotating shaft 3 does not rotate) until the irradiation lamp 2 is reset.

[0021] like Figure 2-Figure 8 As shown, the demoulding mechanism includes: a first plate 901, which is slidably connected to the seedling box 6; a vertical rod 902, which is fixedly connected to the first plate 901; a seedling shell 903, which is installed on the seedling box 6, and the seedling shell 903 is provided with a groove that runs through the body, and the groove is squeezed and matched with the vertical rod 902, and there is a gap between the two, and a depression is provided on the outer wall of the seedling shell 903, and a protrusion is provided on the seedling box 6, and the protrusion is squeezed and matched with the depression on the seedling shell 903, so as to gather the seedling shell 903; a second plate 904, which is slidably connected to the seedling box 6; a transmission component, which is arranged in the seedling box 6, used to make the first plate 901 and the seedling box 6 slide relative to each other, the transmission assembly includes: a rotating shaft 1001, rotatably connected to the seedling box 6; a connecting member 1002, more than one of which are all arranged in the seedling box 6, the connecting member 1002 and the rotating shaft 1001 are connected through a worm gear transmission, the worm is fixedly connected to the rotating shaft 1001, the worm wheel is rotatably connected to the seedling box 6 through a support sleeve, and the worm wheel is threadedly matched with the connecting member 1002; a third plate 1003, fixedly connected to the connecting member 1002, the third plate 1003 is in contact with the first plate 901.

[0022] In the above scheme, the seedling shell 903 is an inverted square table, which is convenient for subsequent demoulding and reduces the difficulty of operation for personnel. The upper side of the seedling shell 903 is flush with the adjacent side of the seedling box 6, which is convenient for the subsequent separation of the strawberry seedlings from the seedling shell 903. The seedling shell 903 is filled with a culture medium (such as a nutrient solution and organic soil, etc.). The gap between the through-type groove on the seedling shell 903 and the vertical rod 902 is used to allow the culture medium in the seedling shell 903 to penetrate. The second plate 904 is provided with a through hole, which is also filled with a culture medium, and the axis of the through hole, the axis of the vertical rod 902 and the axis of the seedling shell 903 coincide with each other. When the seedlings are completed and demoulding is required, the staff rotates the rotating shaft 1001, and the rotating shaft 1001 drives the worm to rotate together, and the worm drives the worm wheel to rotate. Under the action of the worm wheel, the connecting member 1002 starts to move upward, and the connecting member 1002 drives the third plate 1003 upward The third plate 1003 drives the first plate 901 to move upwards together, and the first plate 901 drives the vertical rod 902 to move upwards together. After the vertical rod 902 moves upwards to contact with the seedling shell 903, the vertical rod 902 drives the seedling shell 903 to move upwards together. During the process, the protrusion on the seedling box 6 squeezes the depression on the seedling shell 903, so that the seedling shell 903 is gathered toward the center, and the soil and other media therein are squeezed to make the soil and other media wrap the root of the strawberry seedlings, preventing the soil at the root of the strawberry seedlings from being loose during demoulding, thereby affecting the normal transplanting of the strawberry seedlings, and because the soil medium in the through hole of the second plate 904 is "exposed" outside, when transplanting the strawberry seedlings, the staff directly takes the soil of this part (as the strawberry seedlings grow, their root system gradually "fixes" the soil medium in the adjacent area), so as to avoid the soil being wrapped by the seedling shell 903 and causing difficulty in taking out.

[0023] like Figure 2 , Figure 4 and Fig. 9 As shown, the shading mechanism includes: a connecting frame 1101, fixedly connected to the frame body 1; two sliding plates 1102, both slidably connected to the connecting frame 1101, and an elastic element 1103 is fixedly connected between the sliding plate 1102 and the connecting frame 1101; a shell 1104, the number of which is more than two, both of which are fixedly connected to the connecting frame 1101; a first rotating member 1105, the number of which is the same as the number of the shell 1104, which is rotatably connected to the shell 1104, and the first rotating member 1105 is connected to the rotating shaft 3 through a gear set transmission; a connecting rope 1106 arranged symmetrically at the center, one end of which is fixedly connected to the adjacent first rotating member 1105; a shading plate 1107, fixedly connected to the other end of the connecting rope 1106 arranged symmetrically at the center, and the shading plate 1107 is an arched plate, which is used to block the passing seedling box 6 with the same trajectory.

[0024] In the above scheme, the elastic element 1103 is a spring, which is used to reset the adjacent sliding plate 1102. The gear set is a reduction planetary gear set, which includes a central gear, three planetary gears and an inner gear ring. The central gear is fixedly connected to the rotating shaft 3, and the planetary gears are rotatably connected to the first rotating member 1105. The inner gear ring is arranged on the housing 1104. The three planetary gears and the inner gear ring are all meshed with the central gear. During the rotation of the rotating shaft 3, the rotating shaft 3 drives the central gear to rotate together, and the central gear drives the planetary gears to roll along the inner gear ring, and the planetary gears drive the first rotating member 1105. Rotating together, the first rotating member 1105 reels the adjacent connecting rope 1106, the shading plate 1107 is deformed (moves inwardly) under tension, the two sliding plates 1102 are squeezed by the shading plate 1107 and begin to move toward each other, the elastic element 1103 is compressed, and the shading plate 1107 is pulled inwardly through the connecting rope 1106, thereby reducing the degree of light blocking by the shading plate 1107, matching the lighting duration with the growth of the strawberry seedlings, and preventing the phenomenon of delayed flower bud differentiation caused by too short lighting time, thereby extending the growth cycle of the strawberry and delaying the production period.

[0025] like Figure 1 , Figure 4 and Fig.10 As shown, it also includes: a support member 1201, fixedly connected to the frame 1; a second rotating member 1202, rotatably connected to the support member 1201, the support member 1201 and the second rotating member 1202 are both provided with cavities and are connected to each other; a first tube 1203, fixedly connected between the frame 1 and the support member 1201, the first tube 1203 is connected to the cavity on the support member 1201; a second tube 1204, one end of which is fixedly connected to the second rotating member 1202, the second tube 1204 is connected to the cavity on the second rotating member 1202, the frame 1 is provided with a cavity 1205, and the cavity 1205 is connected to the first tube 1203; a first extrusion member 1206, slidably connected to the cavity 1205, the first extrusion member 1206 is fixedly connected to the irradiation lamp 2; the support frame 120 7, fixedly connected to the frame 1; a rotating shell 1208, rotatably connected to the support frame 1207, and the rotating shell 1208 is connected to the other end of the second tube 1204; a third tube 1209, fixedly connected to the seedling box 6, the third tube 1209 is made of a hard material, and the third tube 1209 is fixedly connected to the rotating shell 1208, and is used to transmit torque to the third tube 1209, the third tube 1209 is connected to the rotating shell 1208, and the cavities on the support member 1201 and the second rotating member 1202, the first tube 1203, the second tube 1204, the cavity 1205, the rotating shell 1208 and the third tube 1209 are all filled with transmission medium; a second extrusion member 1210, slidably connected to the third tube 1209, and the second extrusion member 1210 is extruded and matched with the second plate 904.

[0026] In the above scheme, the cavity 1205 is cylindrical, and its diameter is greater than the inner diameter of the first tube 1203, which is used to increase the relative movement distance between the second plate 904 and the seedling box 6. The second tube 1204 and the rotating shell 1208 are both made of plastic, which are used to reduce weight and reduce resistance during rotation. The inner side of the support frame 1207 is an arc surface, which is used to increase the contact area with the rotating shell 1208, thereby improving the stability of the rotating shell 1208 during rotation. The transmission medium in the cavity on the support member 1201 and the second rotating member 1202, the first tube 1203, the second tube 1204, the cavity 1205, the rotating shell 1208 and the third tube 1209 is hydraulic oil. When the irradiation lamp 2 moves downward, the irradiation lamp 2 drives the first extrusion member 1206 to move downward together, and the first extrusion member 1206 moves the cavity 12 05 is squeezed into the first tube 1203, the hydraulic oil in the first tube 1203 passes through the cavities on the support 1201 and the second rotating part 1202 and then enters the second tube 1204, the hydraulic oil in the second tube 1204 enters the third tube 1209 through the rotating shell 1208, the hydraulic oil in the third tube 1209 squeezes the second extrusion piece 1210, the second extrusion piece 1210 moves upward, the second extrusion piece 1210 drives the second plate 904 to move upward together, the distance between the second plate 904 and the seedling shell 903 increases, the second plate 904 carries the soil in its through hole through friction and moves upward together, thereby improving the looseness of the soil, increasing the soil permeability, and preventing the soil from being squeezed and becoming compacted as the root system of the strawberry seedlings gradually develops as the strawberry seedlings grow, affecting the oxygen supply, and restricting the breathing and growth of the strawberry roots.

[0027] In addition, it should be understood that although the present specification is described in terms of implementation modes, not every implementation mode contains only one independent technical solution.
