Description

Technical Field

[0001] The present invention relates to the technical field of greenhouse planting, and particularly to a Fritillaria cirrhosa D. Don planting greenhouse with high survival rate. Background Art

[0002] Fritillaria cirrhosa D. Don is a rare Chinese medicinal material. Due to its high medicinal value and large market demand, the wild Fritillaria cirrhosa D. Don resources are increasingly depleted due to over-excavation, and artificial planting has become an important way to solve the shortage of resources. However, Fritillaria cirrhosa D. Don has extremely strict requirements for the growth environment and is suitable for growing in high-altitude, low-temperature, and humid environments, and has a long growth cycle. The traditional open-field planting method is affected by factors such as climate, soil, and pests and diseases, with a low survival rate and difficult to meet the needs of large-scale production. In recent years, greenhouse planting technology has been gradually introduced to improve the planting efficiency and survival rate of Fritillaria cirrhosa D. Don. Greenhouse planting can simulate the natural growth conditions of Fritillaria cirrhosa D. Don by artificially regulating environmental factors such as temperature, humidity, and light, reducing the adverse effects of the external environment, thereby improving the survival rate of plants and the quality of medicinal materials. In greenhouse planting, to ensure the survival rate, precise water volume control is required. In the prior art, neither drip irrigation nor sprinkler irrigation can accurately ensure soil humidity, and the survival rate is still not high enough. Summary of the Invention

[0003] In view of the above technical problems, the present invention discloses a Fritillaria cirrhosa D. Don planting greenhouse with high survival rate, including a bottom plate, on which a plurality of greenhouse skeletons are equidistantly installed for laying a film. A plurality of tidal bed assemblies are installed on the bottom plate. The tidal bed assembly includes a support frame, on which a barrier strip is installed. The barrier strip divides the upper side of the support frame into two areas, a water channel and a medicine channel. A seedling placing plate is installed on the support frame, and a plurality of seedling placing seats capable of switching between the water channel and the medicine channel areas are installed on the seedling placing plate, and the seedling placing seats switch between the water channel and the medicine channel areas. Through the above technical solution, the use of the tidal bed assembly can accurately control the watering volume. Precise water volume control is required for the cultivation of Fritillaria cirrhosa D. Don seedlings. Therefore, the use of the tidal bed assembly can greatly improve the survival rate. At the same time, by setting the two areas of the water channel and the medicine channel, watering, adding medicine, or fertilizing can be carried out separately, which can avoid inaccurate dosing caused by drug residues to the greatest extent, and also make the most of the space on the support frame. There needs to be a gap between the Fritillaria cirrhosa D. Don seedlings themselves, and the reciprocating switching seedling placing seats also make one of the water channel and the medicine channel always idle and act as a gap.

[0004] Further, a second hinge rod and a first hinge rod are hinged on the support frame, and the ends of the first hinge rod and the second hinge rod are jointly hinged with the seedling placing plate to form a parallelogram structure.

[0005] Further, a plurality of seedling sliding grooves are provided on the seedling placing plate, and the plurality of seedling placing seats are respectively slidably connected in the plurality of seedling sliding grooves, and the width of the seedling placing seat is smaller than the width of the seedling sliding groove.

[0006] Furthermore, the medicine - passing grooves and water - passing grooves are arranged alternately. A medicine - passing pipeline is arranged on the lower side of the medicine - passing groove, and the medicine - passing pipeline is connected to a medicine box. The lower side of the water - passing groove is connected to a water - passing pipeline, and a water tank is arranged on the lower side of the water - passing pipeline. The seedling - placing seat switches between the water - passing groove and the medicine - passing groove. Through the above technical solution, during the switching process, the bottom of the seedling - placing seat will not interfere with the barrier strip. When the bottom of the seedling - placing seat enters the water - passing groove or the medicine - passing groove, the seedling - placing plate can still continue to fit against the upper side of the barrier strip downward. At this time, the seedling - placing seat will slide in the seedling - sliding groove to a lower position, thereby enabling water to enter the seedling - placing seat faster.

[0007] Furthermore, a plurality of temperature - regulating structures corresponding to the positions of a plurality of greenhouse frameworks are installed on the bottom plate. The temperature - regulating structure includes an air - passing pipe. Both ends of the air - passing pipe are fixedly and communicatively connected to a bottom - layer pipeline. A hoop is arranged on the bottom - layer pipeline and fixedly connected to the bottom plate. Upper - layer ventilation holes are arranged on the air - passing pipe, and lower - layer ventilation holes are arranged on the bottom - layer pipeline. The lower - layer ventilation holes open downward. Ventilation fans are symmetrically arranged on the surface of the air - passing pipe, and the ventilation fans are used to assist air circulation. Through the above technical solution, hot air accumulates at the top of the greenhouse. The ventilation fans allow the hot air at the top to enter the air - passing pipe through the upper - layer ventilation holes, and then is discharged downward through the lower - layer ventilation holes after passing through the bottom - layer pipeline, which can better regulate the temperature in the greenhouse, and the downward blowing air will not directly act on the bottom of the greenhouse framework, preventing local overheating and affecting the regulation.

[0008] Furthermore, the greenhouse framework includes an arched frame. The arched frame is fixedly installed on the bottom plate. A groove is opened on the upper side of the arched frame, and a mounting seat is slidably installed in the groove. A first end of the mounting seat is fixedly connected to a pull rope, and a second end of the mounting seat is used to clamp a film. The film is laid on the arched frame by dragging the mounting seat through the pull rope. A hinge wheel is rotatably installed at a first end of the arched frame, and the pull rope is hinged on the hinge wheel.

[0009] Furthermore, a pressing groove is arranged at the second end of the mounting seat. A pressing plate is slidably installed in the pressing groove. A bolt is rotatably installed at the upper end of the pressing plate. A threaded hole is arranged on the mounting seat to cooperate with the bolt, and the pressing plate is used to clamp the film. Through the above technical solution, the film is loaded on the pressing plate, and the mounting seat can reach the other end of the arched frame by sliding along the upper side of the arched frame, reducing the laying difficulty and improving the laying quality.

[0010] Furthermore, a clamping groove is arranged on the upper side of the second end of the mounting seat. A clamping block is fixedly installed on the upper side of the clamping groove. A fixing rope is clamped on the clamping block, and the fixing rope is located above the film. The film is pressed by the fixing rope during the laying process.

[0011] Further, a winch seat is fixedly installed at the second end of the arched frame. A rotating shaft is rotatably installed on the winch seat. A fixing rope is hinged on the rotating shaft, and the rotation of the rotating shaft is resisted by the winch seat. Through the above technical solution, during the movement of the mounting seat, the fixing rope presses the film on the upper side of the film. Therefore, during the laying process, the film is also fixed simultaneously, greatly improving the laying efficiency.

[0012] The beneficial effects of the present invention compared with the prior art are as follows:

[0013] (1) Through the technical solution of the present invention, the tidal bed assembly can accurately control the watering amount. Water will be lost in conventional drip irrigation and sprinkler irrigation, but on the tidal bed assembly, the Fritillaria cirrhosa seedlings can be fully supplemented with water without loss, which is convenient for precise control. The cultivation of Fritillaria cirrhosa itself requires precise water control. Therefore, using the tidal bed assembly can greatly improve the survival rate. At the same time, by setting two areas of a water channel and a medicine channel, watering, adding medicine, or fertilizing can be carried out separately, which can avoid the inaccuracy of dosage caused by drug residues to the greatest extent, and also make the best use of the space on the support frame. Moreover, there is a need to leave gaps between the Fritillaria cirrhosa seedlings themselves. Therefore, the reciprocating switching of the seedling placing seats also makes one of the water channel and the medicine channel always idle, so as to act as a gap.

[0014] (2) Through the technical solution of the present invention, the bottom of the seedling placing seat will not interfere with the barrier strip during the switching process. When the bottom of the seedling placing seat enters the water channel or the medicine channel, the seedling placing plate can still continue to fit the upper side of the barrier strip downward. At this time, the seedling placing seat will slide in the seedling sliding groove and reach a lower position, thereby enabling water to enter the seedling placing seat faster.

[0015] (3) Through the technical solution of the present invention, hot air accumulates at the top of the greenhouse. The top hot air is allowed to enter the ventilation pipe through the upper ventilation holes by the ventilation fan, and then discharged downward from the lower ventilation holes through the bottom pipeline, which can better adjust the temperature in the greenhouse, and the downward blowing air will not directly act on the bottom of the greenhouse skeleton, preventing local overheating and affecting the adjustment.

[0016] (4) Through the technical solution of the present invention, the film is loaded on the pressing plate, and the mounting seat can reach the other end of the arched frame by sliding along the upper side of the arched frame, reducing the laying difficulty and improving the laying quality.

[0017] (5) Through the technical solution of the present invention, during the movement of the mounting seat, the fixing rope presses the film on the upper side of the film. Therefore, during the laying process, the film is also fixed simultaneously, greatly improving the laying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1 - 10 shown, a Fritillaria cirrhosa planting greenhouse with high survival rate includes a bottom plate 4, on which a plurality of greenhouse skeletons 1 are installed. A film is laid on the greenhouse skeletons 1. A plurality of tidal bed assemblies 3 are equidistantly installed on the bottom plate 4. A plurality of cross beams 5 are fixedly installed between the plurality of greenhouse skeletons 1. The film is supported by the greenhouse skeletons 1 and the cross beams 5. As a support for the film, a temperature regulating structure 2 is also installed on the bottom plate 4, and the temperature regulating structure 2 is used to adjust the temperature inside the greenhouse.

[0031] In this embodiment, the tidal bed assembly 3 includes a support frame 316. Four corners of the bottom end of the support frame 316 are provided with feet. The upper side of the support frame 316 is grooved inward. A barrier strip 315 is installed on the support frame 316. The barrier strip 315 divides the upper side of the support frame 316 into two areas, namely a water passing groove 311 and a medicine passing groove 312. The barrier strip 315 is meandering, and the shapes of the water passing groove 311 and the medicine passing groove 312 divided are strip-shaped and are arranged alternately. A seedling placing plate 308 is installed on the support frame 316. A seedling placing seat 310 is slidably installed on the seedling placing plate 308. A sliding strip 309 is fixedly installed on the seedling placing plate 308. The seedling placing seat 310 is slidably connected through the sliding strip 309. A second hinge rod 307 and a first hinge rod 306 are hinged on the support frame 316. The ends of the first hinge rod 306 and the second hinge rod 307 are jointly hinged with the seedling placing plate 308 to form a parallelogram structure. The seedling placing seat 310 switches between the two areas of the water passing groove 311 and the medicine passing groove 312.

[0032] In this embodiment, the second hinge rod 307 and the first hinge rod 306 are hinged to the support frame 316 at the middle position, and the upper ends are hinged with a seedling placing plate 308. The lower ends of the first hinge rod 306 and the second hinge rod 307 are hinged with a bottom layer rod 303. The first blocking block 304 and the second blocking block 305 are fixedly installed on the bottom layer rod 303. A pushing bar 302 is slidably installed vertically between the first blocking block 304 and the second blocking block 305. A cylinder 301 is fixedly installed on the bottom plate 4, and the pushing bar 302 is fixedly installed on the cylinder arm of the cylinder 301. Through the above technical solution, the temperature control structure 2 can accurately control the watering amount. The cultivation of Fritillaria cirrhosa itself requires accurate water control, so the use of the temperature control structure 2 can greatly improve the survival rate. At the same time, by setting two areas of a water passing groove 311 and a medicine passing groove 312, watering, adding medicine or fertilizing can be carried out separately, which can avoid the inaccurate dosage caused by drug residues to the greatest extent, and also make the best use of the space on the support frame 316. Moreover, there needs to be a gap between the Fritillaria cirrhosa seedlings themselves. Therefore, the reciprocating switching seedling placing seat 310 also makes one of the water passing groove 311 and the medicine passing groove 312 always idle, so as to serve as a gap.

[0033] In this embodiment, a plurality of seedling sliding grooves 319 are provided on the seedling placing plate 308, and a plurality of the seedling placing seats 310 are respectively slidably connected in the plurality of seedling sliding grooves 319. The width of the seedling placing seat 310 is smaller than the width of the seedling sliding groove 319. The medicine passing groove 312 and the water passing groove 311 are arranged alternately. A medicine passing pipeline 313 is provided on the lower side of the medicine passing groove 312, and the medicine passing pipeline 313 is connected to a medicine box 317. The lower side of the water passing groove 311 is connected to a water passing pipeline 314, and a water tank 318 is provided on the lower side of the water passing pipeline 314. The seedling placing seat 310 switches between the water passing groove 311 and the medicine passing groove 312. If the seedling placing plate 308 is fixedly connected to the seedling placing seat 310, then when switching, it is necessary to cross the barrier strip 315. This requires that the bottom end of the seedling placing seat 310 cannot be too much lower than the bottom end of the seedling placing plate 308, otherwise it is easy to interfere with the barrier strip 315. To prevent the barrier strip 315 from interfering, the widths of the water passing groove 311 and the medicine passing groove 312 need to be larger, and a larger width will reduce the number of rows of the seedling placing seat 310 and reduce the usable area. In practical applications, it is necessary to make the bottom of the seedling placing seat 310 extend into the water passing groove 311 or the medicine passing groove 312 as much as possible, which requires the seedling placing seat 310 to be lower. For example Figure 10, during the process of the lower end of the seedling placement plate 308 fitting with the upper end of the barrier strip 315, the seedling placement plate 308 will drive the seedling placement seat 310 to continue fitting to the left. As long as the bottom of the seedling placement seat 310 is slightly lower than the barrier strip 315, the side of the barrier strip 315 fitting with the seedling placement seat 310 will not be interfered at this time. And the seedling placement plate 308 drives the seedling placement seat 310 to continue moving downward. When switching, the bottom of the seedling placement seat 310 will not interfere with the barrier strip 315. When the bottom of the seedling placement seat 310 enters the water trough 311 or the medicine trough 312, the seedling placement plate 308 can still continue to fit the upper side of the barrier strip 315 downward. At this time, the seedling placement seat 310 will slide in the seedling sliding groove 319 to reach a lower position, so that water can enter the seedling placement seat 310 faster.

[0034] In this embodiment, a plurality of temperature adjustment structures 2 corresponding to the positions of a plurality of greenhouse frames 1 are installed on the bottom plate 4. The temperature adjustment structure 2 includes an air duct 201. Both ends of the air duct 201 are fixedly connected and communicated with a bottom layer pipeline 204. A hoop is arranged on the bottom layer pipeline 204 and fixedly connected to the bottom plate 4. An upper ventilation hole 202 is arranged on the air duct 201, and a lower ventilation hole 205 is arranged on the bottom layer pipeline 204. The lower ventilation hole 205 opens downward; ventilation fans 203 are symmetrically arranged on the surface of the air duct 201, and the ventilation fans 203 assist in air circulation. Through the above technical solution, hot air accumulates at the top of the greenhouse. The ventilation fans 203 allow the hot air at the top to enter the air duct 201 through the upper ventilation holes 202, and then is discharged downward from the lower ventilation holes 205 through the bottom layer pipeline 204, which can better adjust the temperature in the greenhouse, and the downward blowing will not directly act on the bottom of the greenhouse frame 1, preventing local overheating and affecting the adjustment.

[0035] In this embodiment, the greenhouse frame 1 includes an arched frame 101. The arched frame 101 is fixedly installed on the bottom plate 4. A groove is opened on the upper side of the arched frame 101, and a mounting seat 109 is slidably installed in the groove. A sliding block 116 is fixedly installed at the lower end of the mounting seat 109. The mounting seat 109 is slidably installed in the groove through the sliding block 116. A pulling rope 117 is fixedly connected to the first end of the mounting seat 109. The second end of the mounting seat 109 is used for clamping the film. The mounting seat 109 is dragged by the pulling rope 117 to drive the film to be laid on the arched frame 101. A hinge wheel 108 is rotatably installed at the first end of the arched frame 101, and the pulling rope 117 is hinged on the hinge wheel 108.

[0036] In this embodiment, a pressing groove 115 is provided at the second end of the mounting seat 109. A pressing plate 114 is slidably mounted in the pressing groove 115. A bolt 113 is rotatably mounted at the upper end of the pressing plate 114. A threaded hole is provided on the mounting seat 109 to cooperate with the bolt 113. The pressing plate 114 is used to clamp the film. A clamping groove 110 is provided on the upper side of the second end of the mounting seat 109. A clamping block 111 is fixedly mounted on the upper side of the clamping groove 110. A fixing rope 112 is clamped on the clamping block 111. The fixing rope 112 is located above the film. The film is pressed by the fixing rope 112 during the laying process. Through the above technical solution, the film is loaded on the pressing plate 114. The mounting seat 109 can slide along the upper side of the arch frame 101 to reach the other end of the arch frame 101, reducing the laying difficulty and improving the laying quality.

[0037] In this embodiment, a winch seat 102 is fixedly mounted at the second end of the arch frame 101. A rotating shaft 103 is rotatably mounted on the winch seat 102. The fixing rope 112 is hinged on the rotating shaft 103. The rotation of the rotating shaft 103 is resisted by the winch seat 102. Specifically, a support frame 107 is fixedly mounted on the winch seat 102. A friction pin 106 is slidably mounted at the upper end of the support frame 107. A friction plate 104 is fixedly mounted at the lower end of the friction pin 106. The friction plate 104 is arc-shaped. The bottom end of the arc is in contact with the rotating shaft 103. A friction spring 105 is fixed between the support frame 107 and the friction pin 106. The rotating shaft 103 is pressed by the friction plate 104 through the friction spring 105. When the mounting seat 109 slides, the fixing rope 112 on the rotating shaft 103 is pulled. Through the above technical solution, during the movement of the mounting seat 109, the fixing rope 112 presses the film above the film. Therefore, the film is also fixed during the laying process, greatly improving the laying efficiency.

[0038] Working principle: The bottom plate 4 can be replaced by the ground or laid separately. The arch frame 101 is connected to the bottom plate 4 by welding. The film is clamped on all the pressing plates 114. The bolt 113 is rotated to press the film. One end of the film is fixed on the pressing plate 114, and the other end is placed on the original reel and buried underground. The film is a whole piece and is laid on the arch frame 101 entirely. In the prior art, it is necessary to manually pull a whole piece of film from one end of the arch frame 101 to the other end. However, in this embodiment, it is not necessary to climb onto the arch frame 101. It can be achieved by manual rotation or electric drive. The fixing rope 112 is pulled out from the rotating shaft 103 and stuck in the clamping groove 110. Then the winch 108 is manually rotated. The winch 108 can be driven by a motor. In this embodiment, it is manually driven. All the winches 108 are started simultaneously. The winches 108 are installed on the arch frame 101, and the mounting seat 109 is in the groove on the arch frame 101. The pulling rope 117 starts to pull the mounting seat 109 to slide, and the film is spread little by little and laid on all the arch frames 101. At the same time, the fixing rope 112 will also be pulled. However, due to the friction plate 104 pressing against the rotating shaft 103, there is a certain resistance, and the fixing rope 112 is always tightened, which is beneficial to pressing the laid film. Since it moves along the arch frame 101, the fixing rope 112 will be pressed in the groove on the arch frame 101. Finally, the mounting seat 109 moves to the limit position and cannot move. The film is taken off from the pressing plate 114. This height does not require climbing, and then it is buried underground. The first end of the film is also buried underground, and the laying is completed.

[0039] Then place the Fritillaria cirrhosa seeds in the seedling placing seat 310 for cultivation. First, replenish water. The telescopic shaft of the cylinder 301 at the initial position is in the middle position where it is extended halfway, and the first hinge rod 306 and the second hinge rod 307 are also in the vertical state. Start the cylinder 301. The telescopic shaft of the cylinder 301 extends, driving the second hinge rod 307 and the first hinge rod 306 through the bottom layer rod 303. The first hinge rod 306 and the second hinge rod 307 drive the seedling placing plate 308 to gradually approach the support frame 316, driving the seedling placing seat 310 into the water through-flow tank 311. Then, the water in the water tank 318 enters the water through-flow tank 311 through the water pipeline 314. At this time, water replenishment starts. When the telescopic shaft of the cylinder 301 moves in the reverse direction, it can drive the seedling placing plate 308 through the first hinge rod 306 and the second hinge rod 307, and the seedling placing seat 310 leaves the water through-flow tank 311 and enters the medicine through-flow tank 312. The medicine or fertilizer in the medicine box 317 enters the seedling placing seat 310 through the medicine pipeline 313. After the replenishment is completed, make the first hinge rod 306 and the second hinge rod 307 in the vertical state. The seedling placing plate 308 drives the seedling placing seat 310 to be at a high position, leaving the water through-flow tank 311 and the medicine through-flow tank 312. The reason for making the width of the seedling sliding groove 319 larger than the seedling placing seat 310 here is that if the seedling placing seat 310 is fixedly installed on the seedling placing plate 308, then the depth of entering the water through-flow tank 311 and the medicine through-flow tank 312 is limited. However, if the seedling placing seat 310 can slide horizontally in the seedling sliding groove 319, then it can be designed that the lower end of the seedling placing plate 308 fits the upper end of the support frame 316, as Figure 10 shown in. Taking the leftmost end in the figure as an example, at this time, if the seedling placing plate 308 continues to move to fit the support frame 316, during the process, it will drive the seedling placing seat 310 to fit one side of the water through-flow tank 311. When the seedling placing plate 308 continues to move downward while the seedling placing seat 310 cannot move leftward continuously, then the seedling sliding groove 319 will slide and compensate relative to the seedling placing seat 310, and the seedling placing plate 308 drives the seedling placing seat 310 to continue downward until the lower end of the seedling placing plate 308 fits the upper end of the support frame 316 and the upper end of the barrier strip 315. On the contrary, the same situation also occurs in the medicine through-flow tank 312.

[0040] During the cultivation process, it is necessary to ensure the temperature. Start the ventilation fan 203 to ventilate the hot air in the upper part of the greenhouse to the lower part to form a heat cycle and ensure the temperature in the greenhouse.

[0041] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above-mentioned drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
