Description

Technical Field

[0001] The invention relates to the technical field of strawberry seedling cultivation, and in particular to a multifunctional strawberry elevated seedling cultivation device and a seedling cultivation method thereof. Background Art

[0002] Strawberry is a perennial herb. It is a red fruit that is fresh, tender, juicy, sweet and sour, and has high nutritional value. It is known as the "Queen of Fruits". With the rapid development of strawberry seedling technology, in order to facilitate the daily management of strawberries, avoid workers from bending over for a long time, and improve work efficiency, the application of strawberry elevated seedling technology in seedling technology has become more and more common. As the name suggests, strawberry elevated seedlings are to place seedling trays or seedling pots with strawberry plants on an elevated seedling bed for cultivation and management. The elevated seedling bed consists of a hollow mesh plate and multiple support columns fixed to the bottom of the hollow mesh plate to raise the hollow mesh plate. During seedling cultivation, the elevated seedling beds are arranged along the length of the greenhouse, and aisles are provided between adjacent elevated seedling beds to facilitate the daily management of the strawberry plants in the elevated seedling beds (including pruning, removing dead leaves and flowers, etc.). The current strawberry elevated seedling technology has the following shortcomings: (1) Low land utilization rate: Usually, multiple elevated seedling beds are placed in a greenhouse, and multiple aisles are left in the greenhouse. However, these aisles are not used reasonably. Each aisle is relatively wide, and the combined area of all aisles will occupy a large area in the greenhouse, indirectly reducing the seedling area in the greenhouse, reducing the land utilization rate of the greenhouse, and causing a waste of land resources.

[0003] (2) Shading operation is cumbersome: When the temperature is too high and the sunlight is strong in the summer, the strawberry plants need to be shaded. When shading, shade nets are usually set up above the elevated seedling beds in the morning, and then the shade nets need to be removed in the afternoon. The whole process is relatively troublesome.

[0004] (3) Difficulty in managing a low-light environment: The lower seedbed is prone to insufficient light, which affects the uniformity of seedling growth. Summary of the Invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a multifunctional strawberry elevated seedling raising device and a seedling raising method thereof, which can increase the seedling raising area in the greenhouse, improve the land utilization rate of the greenhouse, avoid waste of land resources, and can automatically provide shade, automatically remove the shade cloth, and provide supplementary light.

[0006] The purpose of the present invention is achieved through the following technical solutions: A multifunctional strawberry elevated seedling raising device comprises a lower support frame and a bottom plate fixed on the lower support frame, at least one seedling raising mechanism is arranged on the bottom plate, each seedling raising mechanism comprises an upper support frame, a seedling raising bed and a shading mechanism; the seedling raising bed comprises a movable seedling bed and a fixed seedling bed; the movable seedling bed is mounted on the bottom plate and can slide back and forth in a direction away from or close to the upper support frame under the action of an external force; the fixed seedling bed is fixed on the upper support frame and is located above the movable seedling bed; the shading mechanism comprises a first net box, a first shading net, a second net box and a second shading net; the first net box It is vertically fixed on the fixed seedling bed and has an opening at the top; the first shade net is vertically placed in the first net box, and can be pushed upwards out of the top opening of the first net box under the push of external force and rotated toward the fixed seedling bed, and then suspended above the fixed seedling bed; the second net box is fixed between the upper support frame and the fixed seedling bed and has an opening on the side away from the upper support frame, and the second shade net is horizontally placed in the second net box. When the movable seedling bed is pushed to a position away from the upper support frame by external force, the second shade net can be pushed out of the side opening of the second net box under the push of external force and suspended above the movable seedling bed.

[0007] Furthermore, the movable seedbed and the fixed seedbed are hollow plates with a hollow top and closed sides and bottom, and sewage pipes with valves are provided at the ends of both.

[0008] Furthermore, the seedling bed also includes a plurality of first push-pull mechanisms arranged on the bottom plate; each first push-pull mechanism includes a slide groove, a slider, a first automatic telescopic rod and a connecting rod; the slide groove is arranged on the bottom plate along the sliding direction of the movable seedling bed and passes through the upper and lower surfaces of the bottom plate; the slider is slidably arranged in the slide groove, the upper end of the slider is fixedly connected to the movable seedling bed, and the lower end of the slider extends below the slide groove; the first automatic telescopic rod is fixed on the bottom plate and perpendicular to the sliding direction of the movable seedling bed; one end of the connecting rod is hinged to the lower end of the slider, and the other end is hinged to the telescopic end of the first automatic telescopic rod.

[0009] Furthermore, the shade-shading mechanism also includes a plurality of second push-pull mechanisms and a plurality of third push-pull mechanisms; each second push-pull mechanism includes a second automatic telescopic rod, which is vertically fixed on the bottom plate and located directly below the first net box, and the telescopic end of the second automatic telescopic rod moves upward through the fixed seedling bed and extends into the first net box and is hinged to the first shade net; each third push-pull mechanism includes a third automatic telescopic rod and a push rod; the third automatic telescopic rod is fixed on the second net box and is perpendicular to the sliding direction of the second shade net; the push rod is arranged in the second net box, one end of the push rod is hinged to the telescopic end of the third automatic telescopic rod, and the other end is hinged to the second shade net.

[0010] Furthermore, the first automatic telescopic rod, the second automatic telescopic rod and the third automatic telescopic rod are all any one of an electric cylinder, a pneumatic cylinder and a hydraulic cylinder.

[0011] Furthermore, in order to improve the stability of the structure and stably support and fix the seedbed, an inclined support plate is provided between the bottom of the second net box and the upper support frame.

[0012] Furthermore, the lower support frame, upper support frame and diagonal support plate are solid plate structures or hollow frame structures. Considering the cost and ease of maintenance, the hollow frame structure is preferred, wherein the lower support frame and the upper support frame are both H-shaped structures in cross-section.

[0013] Furthermore, fluorescent lamps are evenly distributed on the lower surface of the diagonal support plate. When the staff performs daily management (including pruning, removing dead leaves and flowers, etc.), it is necessary to retract the movable seedbed onto the bottom plate. At this time, the upper part of the movable seedbed is blocked by the fixed seedbed, and it is necessary to turn on the fluorescent lamps on the lower surface of the diagonal support plate to supplement the light.

[0014] Furthermore, fluorescent lamps are evenly distributed on both sides of the first net box and on the bottom of the second net box. When the light is insufficient, the fluorescent lamp on the side where the light is insufficient is turned on to provide supplementary light.

The two seedling raising mechanisms share an upper support frame, which is located between the two seedling raising beds of the two seedling raising mechanisms; and the two seedling raising mechanisms share a first net cage, which is located between the two seedling raising beds of the two seedling raising mechanisms.

[0016] The method for raising seedlings using the multifunctional strawberry elevated seedling raising device comprises the following steps: S1. Place the seedling trays or pots with strawberry seedlings on the fixed and movable seedbeds and place the drip irrigation pipes.

[0017] S2. When daily seedling management is not required, personnel should evacuate the aisle; slide the movable seedbed out of the bottom plate and position it directly above the aisle.

[0018] S3. When personnel need to enter the aisle to carry out daily management of seedlings, the movable seedbed is slid back to the bottom plate and positioned directly below the fixed seedbed 5. The fluorescent lamp at the bottom of the fixed seedbed is turned on to provide light for the photosynthesis of the plants. After that, the plants on the fixed seedbed 5 and the movable seedbed 4 on the side that needs daily management can be managed. After the management is completed, the movable seedbed is pushed back to the top of the aisle in accordance with step S2 and the fluorescent lamp is turned off.

[0019] S4. When the external sunlight is too strong, push the first shade net in the first net box up and rotate it to be parallel to the fixed seedbed to provide shade for the plants on the fixed seedbed; at the same time, push the second shade net forward to slide out of the second net box so that the second shade net is located above the movable seedbed on the same side thereof to provide shade for the plants on the movable seedbed.

[0020] S5. When the outside sunlight is suitable and no shade is required, the first shade net is pulled back into the first net box to complete the storage of the first shade net; at the same time, the second shade net is pulled into the second net box to complete the storage of the second shade net.

[0021] The present invention provides automatically retractable movable seedling beds on both sides of the fixed seedling bed, making rational use of the greenhouse aisles, increasing the seedling raising area and land utilization rate within the greenhouse, and avoiding waste of land resources. Furthermore, the shade net can be automatically retracted and extended, simplifying the shade operation. The seedling bed adopts a box-type structure, which can promptly collect sewage and dirt flowing out of the bottom of the seedling tray or seedling pot, thereby improving the cleanliness of the seedling bed. A fluorescent lamp is also provided to provide supplementary lighting when the light is weak. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] like Figure 1-9As shown, this embodiment provides a multifunctional elevated strawberry seedling raising device, including a lower support frame 1, a bottom plate 2 and a seedling raising mechanism.

[0040] The lower support frame 1 is a plurality of H-shaped frames placed on the ground.

[0041] The bottom plate 2 is fixed on the lower support frame 1 and together with the lower support frame 1 constitutes the bearing structure of the entire device.

[0042] There are two seedling raising mechanisms which are symmetrically arranged on the bottom plate 2. Each seedling raising mechanism includes an upper support frame 3, a seedling raising bed and a shading mechanism.

[0043] The upper support frame 3 is fixed at the top center of the bottom plate 2 and is used to fix the high seedbed. An H-shaped hollow frame is preferred (taking into account both strength and cost).

[0044] The seedling bed includes a movable seedling bed 4 , a fixed seedling bed 5 and a plurality of first push-pull mechanisms arranged on the bottom plate 2 .

[0045] The movable seedbed 4 is installed on the bottom plate 2 and can slide back and forth in a direction away from or close to the upper support frame 3 under the push of the first push-pull mechanism. It can be moved horizontally outward to the space above the aisle and nested directly under the fixed seedbed 5 when retracted.

[0046] The fixed seedbed 5 is fixed on the upper support frame 3 and is located above the movable seedbed 4.

[0047] Each first push-pull mechanism includes a chute 10, a slider 11, a first automatic telescopic rod 12, and a connecting rod 13. The chute 10 is arranged on the base plate 2 along the sliding direction of the movable seedbed 4 and extends through the upper and lower surfaces of the base plate 2. The slider 11 slides within the chute 10, with the upper end of the slider 11 fixedly connected to the movable seedbed 4 and the lower end of the slider 11 extending below the chute 10. The lower support frame 1 is provided with a through hole for the slider 11 and the telescopic end of the first automatic telescopic rod 12 to pass through. The first automatic telescopic rod 12 is fixed to the base plate 2 and is perpendicular to the sliding direction of the movable seedbed 4. One end of the connecting rod 13 is hinged to the lower end of the slider 11, and the other end is hinged to the telescopic end of the first automatic telescopic rod 12. The two seedling raising mechanisms share an upper support frame 3, which is located between the two seedling raising mechanisms.

[0048] The shade-shading mechanism includes a first net box 6, a first shade net 7, a second net box 8, a second shade net 9, and a plurality of second push-pull mechanisms and a plurality of third push-pull mechanisms.

[0049] The first net box 6 is vertically fixed on the fixed seedbed 5 and has an open top. A guide slope 19 is provided inside the first net box 6 on a side facing the fixed seedbed 5 .

[0050] The first shade net 7 is placed vertically in the first net box 6, and a counterweight block 18 is fixed on the top of the first shade net 7 close to the side of the fixed seedling bed 5. The first shade net 7 can be pushed upward out of the top opening of the first net box 6 and rotated toward the fixed seedling bed 5 under the push of the second push-pull mechanism (the first shade net 7 rotates toward the fixed seedling bed 5 under the action of the gravity of the counterweight block 18 on the top of the first shade net 7), and then suspended above the fixed seedling bed 5.

[0051] The second net box 8 is fixed between the upper support frame 3 and the fixed seedbed 5 and is open on the side away from the upper support frame 3. The second shade net 9 is placed horizontally in the second net box 8. When the movable seedbed 4 is pushed to a position away from the upper support frame 3 by the first push-pull mechanism, the second shade net 9 can be pushed out of the side opening of the second net box 8 under the push of the third push-pull mechanism and suspended above the movable seedbed 4.

[0052] Each second push-pull mechanism includes a second automatic telescopic rod 14, which is vertically fixed on the base plate 2 and located directly below the first net box 6 (inside the upper support frame 3), and the telescopic end of the second automatic telescopic rod 14 moves upward through the second net box 8 and the fixed seedling bed 5, and then extends into the first net box 6 and is hinged to the lower end of the first shade net 7.

[0053] Each third push-pull mechanism includes a third automatic telescopic rod 15 and a push rod 16; the third automatic telescopic rod 15 is fixed on the second net box 8 and is perpendicular to the sliding direction of the second shade net 9; the push rod 16 is arranged in the second net box 8, and one end of the push rod 16 is hinged to the telescopic end of the third automatic telescopic rod 15, and the other end is hinged to the second shade net 9.

[0054] At the same time, the two seedling raising mechanisms share a first net box 6, which is located between the two seedling raising mechanisms. The first shade nets 7 of the two seedling raising mechanisms in the first net box 6 are placed vertically side by side, and the counterweight block 18 on the top of the first shade net 7 in each seedling raising mechanism and the guide slope 19 on the inside of the first net box 6 are both arranged toward their respective fixed seedling beds 5.

[0055] The first automatic telescopic rod 12 , the second automatic telescopic rod 14 and the third automatic telescopic rod 15 are all any one of electric cylinders, pneumatic cylinders and hydraulic cylinders.

[0056] Fluorescent lamps are evenly distributed on both sides of the first net box 6 and on the bottom of the second net box 8. When the light is insufficient, the fluorescent lamp on the side with insufficient light is turned on to provide supplementary light. How it works

[0057] Initially, the first shade net 7 is stored in the first net box 6 (the second automatic telescopic rod 14 is retracted), and the second shade net 9 is stored in the second net box 8 (the third automatic telescopic rod 15 is retracted, and the push rod 16 is tucked away beside the third automatic telescopic rod 15). Simultaneously, the movable seedbed 4 is retracted (from above the aisle) onto the base plate 2 and positioned directly below the fixed seedbed 5 (the first automatic telescopic rod 12 is retracted, and the connecting rod 13 is tucked away beside the first automatic telescopic rod 12).

[0058] The steps for raising seedlings are as follows: S1. Place the seedling tray or seedling pot planted with strawberry seedlings on the fixed seedbed 5 and the movable seedbed 4, and place the drip irrigation pipe.

[0059] S2. When routine seedling care (including pruning, removing dead leaves and flowers, etc.) is not required, personnel evacuate the aisle. The first automatic telescopic rod 12 of the first push-pull mechanism is activated. The telescopic end of the first automatic telescopic rod 12 extends forward, pushing the connecting rod 13. The connecting rod 13 pushes the slider 11 along the slide 10 away from the upper support frame 3. The slider 11 pushes the movable seedbed 4 away from the upper support frame 3. After the movable seedbed 4 has mostly slid outside the base plate 2 and is directly above the aisle, the first automatic telescopic rod 12 stops.

[0060] S3. When personnel need to enter the aisle to carry out daily seedling management, the first automatic telescopic rod 12 of the first push-pull mechanism is activated. The telescopic end of the first automatic telescopic rod 12 shortens backward, pulling the connecting rod 13. The connecting rod 13 pulls the slider 11 along the slide 10 toward the upper support frame 3. The slider 11 then pulls the movable seedbed 4 toward the upper support frame 3. After the movable seedbed 4 slides back onto the bottom plate 2 and is located directly below the fixed seedbed 5, the first automatic telescopic rod 12 stops. At this time, the fluorescent lamp at the bottom of the fixed seedbed 5 is turned on to provide light for the plants' photosynthesis. After that, the plants on the fixed seedbed 5 and the movable seedbed 4 on the side that needs daily management can be managed. After the management is completed, the movable seedbed 4 is pushed back to the top of the aisle according to step S2, and the fluorescent lamp is turned off.

[0061] S4. When the external sunlight is too strong, the second automatic telescopic rod 14 of the second push-pull mechanism is started, and the telescopic end of the second automatic telescopic rod 14 extends upward and pushes the first shade net 7 in the first net box 6 to move upward. When the lower end of the first shade net 7 is higher than the guide slope 19 on its respective side, under the action of the respective top counterweight blocks 18 and its own gravity, the first shade net 7 will deflect toward the guide slope 19 on its respective side, and the tops of the two first shade nets 7 will open outward, and the two will gradually separate. As the telescopic end of the second automatic telescopic rod 14 continues to extend upward, the first shade net 7 also rotates toward the fixed seedbed 5 of its respective seedling raising mechanism. After the first shade net 7 rotates to be parallel to the fixed seedbed 5, the second automatic telescopic rod 14 stops, and the first shade net 7 realizes shading of the plants on the fixed seedbed 5. At the same time, the third automatic telescopic rod 15 of the third push-pull mechanism is started, and the telescopic end of the third automatic telescopic rod 15 extends forward to push the push rod 16 to slide forward, and the push rod 16 pushes the second shade net 9 to slide out of the second net box 8. After most of the second shade net 9 slides out of the second net box 8, the third automatic telescopic rod 15 stops. At this time, the second shade net 9 is located above the movable seedbed 4 on the same side, thereby shading the plants on the movable seedbed.

[0062] S5. When the sunlight is adequate and no shade is required, the second automatic telescopic rod 14 of the second push-pull mechanism is activated. The telescopic end of the second automatic telescopic rod 14 retracts downward and pulls the first shade net 7 upward, causing the two first shade nets 7 to close inward. After the first shade net 7 is once again vertical, the telescopic end of the second automatic telescopic rod 14 continues to retract downward, pulling the first shade net 7 back into the first net box 6, completing the storage of the first shade net 7. Simultaneously, the third automatic telescopic rod 15 of the third push-pull mechanism is activated. The telescopic end of the third automatic telescopic rod 15 retracts backward and pulls the push rod 16 to slide backward. The push rod 16 then pulls the second shade net 9 into the second net box 8. After the second shade net 9 has slid back into the second net box 8, the third automatic telescopic rod 15 stops, completing the storage of the second shade net 9. Example 2

[0063] The difference between this embodiment and embodiment 1 is that: The movable seedbed 4 and the fixed seedbed 5 are hollow plates with a hollow top and closed sides and bottom. Sewage pipes with valves are provided at both ends for discharging sewage generated by irrigation or cleaning sewage generated by the movable seedbed 4 and the fixed seedbed 5. Example 3

[0064] The difference between this embodiment and embodiment 1 or embodiment 2 is that: To enhance structural stability and stably support the seedbed 5, a diagonal support plate 17 is provided between the bottom of the second net cage 8 and the upper support frame 3. The lower support frame 1, the upper support frame 3, and the diagonal support plate 17 are either solid plate structures or hollow frame structures. The hollow frame structure is preferred for cost and ease of maintenance. Both the lower support frame 1 and the upper support frame 3 are H-shaped in cross-section. Example 4

[0065] The difference between this embodiment and embodiment 3 is that: Fluorescent lamps are evenly distributed on the lower surface of the diagonal support plate 17. When the staff performs daily management (including pruning, removing dead leaves and flowers, etc.), it is necessary to retract the movable seedbed 4 onto the base plate 2. At this time, the upper part of the movable seedbed 4 will be blocked by the fixed seedbed 5, and it is necessary to turn on the fluorescent lamps on the diagonal support plate 17 and the lower surface of the second net box 8 to supplement the light. Example 5

[0066] The difference between this embodiment and embodiment 4 is that: like Figure 10-12 As shown, in this embodiment, only one seedling raising mechanism is provided on the bottom plate 2, and the structure of the single seedling raising mechanism remains unchanged. When multiple multifunctional strawberry elevated seedling raising devices with two seedling raising mechanisms as described in Example 4 are successively installed in the greenhouse, if the remaining space in the greenhouse is insufficient to install the multifunctional strawberry elevated seedling raising devices as described in Example 4, the multifunctional strawberry elevated seedling raising device with only one seedling raising mechanism as described in this embodiment can be installed in the remaining space to rationally utilize the space in the greenhouse.

[0067] Other aspects of the present invention that are not described in detail are all conventional techniques known to those skilled in the art.

[0068] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements that are inherent to such process, method, article, or apparatus.

[0069] The protection scope of the present invention is not limited to the technical solutions disclosed in the specific implementation methods. Any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the present invention.
