Large-scale seed cultivation device

Abstract

The present invention discloses a large-scale seed cultivation device, which relates to the technical field of seed cultivation, and includes a configuration device and a cultivation device. A control valve is provided at the bottom of one end of the feed pipe away from the feed pump, and a discharge end is provided at one end of the feed pipe away from the feed pump. The cultivation device is arranged on one side of the mobile water tank.

Due to the push of the clean water, the rotating baffle and the hollow plate gather and move the residual nutrient solution on the other side and discharge it into the nutrient solution temporary storage tank. After washing, dry air is injected into the feed pipe through the dry air pipe for air drying, thereby ensuring that the subsequent nutrient solutions of different concentrations are not affected by the concentration of the previous residual nutrient solution during transportation and causing dilution, so as to ensure that the nutrient solution concentration received by the seeds in each cultivation tank meets the preset value.

Description

Technical Field

[0001] The present invention relates to the technical field of seed cultivation, and specifically relates to a device for large-scale cultivation of seeds. Background Technique

[0002] During the seed cultivation process, nutrient solution is often added to improve the growth quality of seeds. The concentration of the nutrient solution is an important factor affecting the quality of seeds. The relationship between the concentration of the nutrient solution and the growth quality of seeds will be explored. Multiple cultivation tanks will be set up and different concentrations of nutrient solution will be injected into them for seed growth, and the growth conditions of the seeds will be observed and recorded regularly.

[0003] When injecting different concentrations of nutrient solution into each cultivation tank on a mesh plate currently, pipelines are used to inject the prepared nutrient solutions of different concentrations into different cultivation tanks. However, during the transportation process of each concentration of nutrient solution, it is inevitable that the nutrient solution will remain in the pipeline, resulting in adverse effects on the next transportation of different concentrations of nutrient solution, and the actually discharged nutrient solution often does not meet the preset concentration value.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a large-scale seed cultivation device is proposed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a large-scale seed cultivation device, which solves the problems proposed in the above background technique.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A large-scale seed cultivation device includes a configuration device and a cultivation device. The configuration device includes a mixing tank. A feeding valve hose is provided at the top of the mixing tank, and a flow meter is provided at the end of the feeding valve hose. The bottom of the mixing tank is connected to a feeding pump through a three-way valve. One connection end of the three-way valve is connected to a mobile water tank through a water suction pipe. The bottom of the feeding pump is connected to a feeding pipe, and an outer pipe support is fixed on the outer wall of the feeding pipe. A servo motor is fixed on one side of the outer pipe support, and the output end of the servo motor is connected to a winding box. A pulling rope is wound inside the winding box. A hollow plate is provided at one end of the feeding pipe close to the feeding pump, and a micro motor is fixed on one side of the hollow plate. The output end of the micro motor is connected to a rotating shutter, and a guiding roller is connected to the outer wall of the micro motor. A control valve is provided at the bottom of the end of the feeding pipe away from the feeding pump, and a return water pipe is connected to the bottom of the control valve. An outlet end is provided at the end of the feeding pipe away from the feeding pump. The cultivation device is arranged on one side of the mobile water tank.

[0007] Further, the interior of the mobile water tank is divided into a water inlet chamber and a water return chamber. The water inlet chamber is communicated with the water suction pipe, and the water return chamber is communicated with the return water pipe. Moreover, both the water suction pipe and the return water pipe are flexible structures.

[0008] Furthermore, one end of the pull rope passes through the feed pipe and is connected to the tail end of the micro motor, and a sealing ring is provided at the penetration position of the pull rope and the feed pipe.

[0009] Furthermore, the end of the guide roller is fitted to the inner wall of the feed pipe, and the outer diameters of the hollow plate and the rotating shielding plate are matched to the inner diameter of the feed pipe.

[0010] Furthermore, the configuration device also includes a dry air pipe, and the other connecting end of the three-way valve is connected to the dry air pipe.

[0011] Furthermore, the culture device includes a support plate, a culture trough, a nutrient solution storage box and an injection pipe. The culture troughs are equidistantly arranged on one side of the surface of the support plate, and the nutrient solution storage box is arranged on the other side of the surface of the support plate. The bottom of the outer wall of the nutrient solution storage box is connected to the injection pipe through a pump body and a flow meter, and a liquid level meter is arranged inside the nutrient solution storage box.

[0012] Furthermore, the culture device also includes a liquid inlet end, and the liquid inlet end is arranged in the middle of the top surface of the nutrient solution temporary storage box.

[0013] Furthermore, the culture device also includes a torsion spring shaft and an induction sealing plate, and one side of the liquid inlet end is elastically connected to the induction sealing plate via the torsion spring shaft.

[0014] Furthermore, the end of the induction sealing plate is in a raised structure, and the raised end of the induction sealing plate exceeds the outer side surface of the liquid inlet end.

[0015] Furthermore, the induction sealing plate and the discharge end are located at the same height, and the side surface of the discharge end is a straight surface structure.

[0016] The present invention provides a large-scale seed cultivation device, which has the following beneficial effects:

[0017] 1. This large-scale seed cultivation device, after each nutrient solution injection, draws clean water through the feed pump to one side of the rotating baffle plate and the hollow plate to flush the inside of the feed pipe, and the rotating baffle plate and the hollow plate are pushed by the clean water to gather and move the residual nutrient solution on the other side and discharge it into the nutrient solution temporary storage box, and after flushing, dry air is injected into the feed pipe through the dry air pipe for air drying, thereby ensuring that the subsequent nutrient solutions of different concentrations are not affected by the concentration of the previous residual nutrient solution and caused to be diluted during transportation, so as to ensure that the nutrient solution concentration of the seeds in each culture tank meets the preset value.

[0018] 2. When the present invention moves the discharge end linearly while carrying the water tank, it gradually approaches the induction sealing plate. When the discharge end adheres to the upturned end of the induction sealing plate, with the subsequent movement of the discharge end pushing down, the induction sealing plate rotates through the torsion spring shaft, thereby exposing the opening of the liquid inlet end. During the subsequent movement, the straight surface on the outside of the discharge end fits against the side surface of the rotating induction sealing plate. At this time, the induction sealing plate is in a vertical state, and the pressure sensing contacts on the surface of the induction sealing plate are evenly stressed. When it is monitored that the stress is uniform, it indicates that the discharge end coincides with the liquid inlet end. At this time, the movement is stopped and liquid injection is carried out to ensure that the nutrient solution accurately enters the interior of the nutrient solution temporary storage tank.

[0019] 3. After the liquid injection is completed, the discharge end of the present invention can continue to move. At this time, the induction sealing plate continues to rotate under force until it completes a 180-degree flip. At this time, the discharge end is separated from the induction sealing plate. At this time, the induction sealing plate resets through the torsion spring shaft and covers the opening of the liquid inlet end again, thereby preventing foreign impurities from entering the interior of the nutrient solution temporary storage tank.

Detailed Implementation Modes

[0027] The following further describes in detail the implementation modes of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0028] As Figures 1 - 6 shown, the large-scale seed cultivation device provided by the present invention includes a configuration device 1 and a cultivation device 3. The configuration device 1 includes a mixing tank 101, a feed valve hose 102, a three-way valve 103, a feeding pump 104, a feeding pipe 105, a water suction pipe 106, a movable water tank 107, an outer pipe bracket 108, a servo motor 109, a winding box 110, a pulling rope 111, a hollow plate 112, a micro motor 113, a guiding roller 114, a rotating baffle 115, a control valve 116 and a return water pipe 117.

[0029] A feed valve hose 102 is arranged at the top of the mixing tank 101, and a flow meter is arranged at the end of the feed valve hose 102. The bottom of the mixing tank 101 is connected to a feeding pump 104 through a three-way valve 103. One connection end of the three-way valve 103 is connected to a movable water tank 107 through a water suction pipe 106. The bottom of the feeding pump 104 is connected to a feeding pipe 105, and an outer pipe bracket 108 is fixed on the outer wall of the feeding pipe 105. A servo motor 109 is fixed on one side of the outer pipe bracket 108, and the output end of the servo motor 109 is connected to a winding box 110. A pulling rope 111 is wound inside the winding box 110. A hollow plate 112 is arranged at one end of the feeding pipe 105 close to the feeding pump 104, and a micro motor 113 is fixed on one side of the hollow plate 112. The output end of the micro motor 113 is connected to a rotating baffle 115, and a guiding roller 114 is connected to the outer wall of the micro motor 113. A control valve 116 is arranged at the bottom of the feeding pipe 105 far from the feeding pump 104, and the bottom of the control valve 116 is connected to a return water pipe 117.

[0030] One end of the feeding pipe 105 far from the feeding pump 104 is provided with a discharge end 2, and the cultivation device 3 is arranged on one side of the movable water tank 107.

[0031] It should be noted that the interior of the movable water tank 107 is divided into a water inlet chamber and a water return chamber. The water inlet chamber is communicated with the water suction pipe 106, and the water return chamber is communicated with the return water pipe 117. Both the water suction pipe 106 and the return water pipe 117 are flexible structures.

[0032] Moreover, one end of the pull rope 111 passes through the material conveying pipe 105 and is connected to the tail end of the micro motor 113. A sealing ring is provided at the penetration part of the pull rope 111 and the material conveying pipe 105. The end of the guiding roller 114 is attached to the inner wall of the material conveying pipe 105, and the outer diameter dimensions of the hollow plate 112 and the rotary shutter 115 are adapted to the inner diameter dimensions of the material conveying pipe 105. The configuration device 1 further includes a dry air pipe 118, and the other connecting end of the three-way valve 103 is connected to the dry air pipe 118.

[0033] The specific operation is as follows. The feed valve hose 102 injects each component required for the nutrient solution for cultivating seeds into the mixing tank 101. During the injection process, the injection amount of each component is controlled by a flow meter, and a concentration meter is arranged inside the mixing tank 101 to monitor the concentration of the mixed nutrient solution.

[0034] When injecting nutrient solutions with different concentrations from low to high into each culture tank 302 in sequence to observe the influence of different concentrations on seed growth, when the concentration meter monitors that the mixing of each component inside the mixing tank 101 reaches the lowest preset concentration, the three-way valve 103 closes the water suction pipe 106 and the dry air pipe 118. Under the action of the material conveying pump 104, the nutrient solution with the lowest concentration is injected into the nutrient solution temporary storage tank 303 along the material conveying pipe 105 and the discharge end 2, and then a preset amount of nutrient solution is injected into the culture tank 302 by the pump body flow meter at the bottom of the nutrient solution temporary storage tank 303.

[0035] Among them, after the nutrient solution is injected into the nutrient solution temporary storage tank 303 along the material conveying pipe 105, the residual nutrient solution inside the material conveying pipe 105 is likely to affect the subsequent nutrient solution with increased concentration, resulting in dilution of the subsequent nutrient solution concentration. Therefore, after the injection of the nutrient solution into the nutrient solution temporary storage tank 303 ends, the three-way valve 103 closes the channel of the mixing tank 101 and opens the water suction pipe 106. At the same time, the micro motor 113 drives the rotary shutter 115 to rotate on the surface of the hollow plate 112, so that the rotary shutter 115 just blocks the hollow part of the hollow plate 112 after rotation.

[0036] Then, the material conveying pump 104 extracts clean water inside the clean water chamber through the water suction pipe 106 and injects it into the material conveying pipe 105. The clean water pushes the rotary shutter 115, the hollow plate 112, and the guiding roller 114 to move along the inside of the material conveying pipe 105, so that the rotary shutter 115 and the hollow plate 112 push the residual liquid to gather and move until the rotary shutter 115 and the hollow plate 112 cross the control valve 116.

[0037] During the process of the rotary shutter 115 and the hollow plate 112 being pushed, the servo motor 109 drives the winding disc inside the winding box 110 to rotate to release the pull rope 111, so that the pull rope 111 is released synchronously with the movement of the micro motor 113.

[0038] After that, the control valve 116 is opened. While the clean water pushes the rotary shutter 115 and the perforated plate 112 to move inside the material conveying pipe 105, the inside of the material conveying pipe 105 is flushed. The water after flushing then returns to the inside of the return water chamber through the opened control valve 116 along the return water pipe 117 to wait for treatment.

[0039] After the above operations are completed, the discharge end 2 injects the nutrient solution with increased concentration into the cultivation tank 302 at the next position. At this time, first, the concentration meter in the previous nutrient solution temporary storage tank 303 determines the concentration of the nutrient solution injected last time, and then based on this concentration, each component is injected into the mixing tank 101 through the feed valve hose 102 until the nutrient solution prepared in the mixing tank 101 reaches the concentration value required for the next cultivation tank 302. By moving the water tank 107 to move uniformly along the preset trajectory, the discharge end 2 reaches the cultivation tank 302 at the next position.

[0040] During the movement, the control valve 116 is closed, the three-way valve 103 closes the channels of the water suction pipe 106 and the mixing tank 101, and opens the channel of the dry air pipe 118. At this time, the dry air pipe 118 injects dry air into the three-way valve 103, the material conveying pump 104, and the inside of the material conveying pipe 105 for air drying to prevent water stains from remaining and affecting the subsequent transmission of the nutrient solution. When reaching the cultivation tank 302 at the next position, the servo motor 109 drives the winding disc inside the winding box 110 to rotate to wind the pulling rope 111, so that the rotary shutter 115 and the perforated plate 112 move in the reverse direction to reset, and at the same time rotate to expose the hollow parts on the surface of the perforated plate 112 for the subsequent transmission of the nutrient solution.

[0041] The present invention injects nutrient solutions with different concentrations into the cultivation tanks 302 at different positions in sequence from low to high to observe the effects of nutrient solutions with different concentrations on seeds. After each injection of the nutrient solution, clean water is pumped by the material conveying pump 104 to flush the inside of the material conveying pipe 105 on one side of the rotary shutter 115 and the perforated plate 112. The rotary shutter 115 and the perforated plate 112 move and gather the residual nutrient solution on the other side due to the push of the clean water and discharge it into the nutrient solution temporary storage tank 303. After flushing, dry air is injected into the material conveying pipe 105 through the dry air pipe 118 for air drying, thereby ensuring that the subsequent nutrient solutions with different concentrations are not affected by the concentration of the residual nutrient solution from the previous time and diluted, so as to ensure that the concentration of the nutrient solution received by the seeds in each cultivation tank 302 meets the preset value.

[0042] Such as Figures 1 - 2As shown, the culture device 3 includes a support plate 301, a culture tank 302, a nutrient solution temporary storage box 303 and an injection pipe 304. The culture tank 302 is equidistantly arranged on one side of the surface of the support plate 301, and the nutrient solution temporary storage box 303 is arranged on the other side of the surface of the support plate 301. The bottom of the outer wall of the nutrient solution temporary storage box 303 is connected to the injection pipe 304 through a pump body and a flow meter, and a liquid level meter is arranged inside the nutrient solution temporary storage box 303.

[0043] The culture device 3 also includes a liquid inlet end 305, and the liquid inlet end 305 is arranged in the middle of the top surface of the nutrient solution temporary storage box 303. The culture device 3 also includes a torsion spring shaft 306 and an induction sealing plate 307. One side of the liquid inlet end 305 is elastically connected to the induction sealing plate 307 through the torsion spring shaft 306. The end of the induction sealing plate 307 has a raised structure, and the raised end of the induction sealing plate 307 exceeds the outer side surface of the liquid inlet end 305. The induction sealing plate 307 is at the same height as the discharge end 2, and the side surface of the discharge end 2 has a straight surface structure.

[0044] The specific operation is as follows: the culture device 3 is fixed, and the mobile water tank 107 will gradually approach the sensing sealing plate 307 when carrying the discharge end 2 to move in a straight line. When the discharge end 2 is attached to the raised end of the sensing sealing plate 307, the discharge end 2 is subsequently moved downward to push the sensing sealing plate 307 to rotate through the torsion spring shaft 306, thereby exposing the opening of the liquid inlet end 305. In the subsequent movement, the straight surface on the outer side of the discharge end 2 is attached to the side of the rotating sensing sealing plate 307. At this time, the sensing sealing plate 307 is vertical, and the pressure sensing contacts on the surface of the sensing sealing plate 307 are evenly stressed. When the uniform force is detected, it indicates that the discharge end 2 coincides with the liquid inlet end 305. At this time, the movement is stopped and liquid is injected.

[0045] After the injection is completed, the discharge end 2 continues to move, and the induction sealing plate 307 is forced to continue to rotate until it completes a 180-degree flip. At this time, the discharge end 2 is separated from the induction sealing plate 307 and moves to the next position of the induction sealing plate 307 and repeats the above operation. After the discharge end 2 is separated from the induction sealing plate 307, the induction sealing plate 307 is reset through the torsion spring shaft 306 to re-cover the opening of the liquid inlet end 305, thereby preventing external impurities from entering the nutrient solution temporary storage box 303.

[0046] In summary, when the large-scale seed cultivation device is used, nutrient solutions of different concentrations from low to high are first injected into each culture tank 302 in sequence to observe the effects of different concentrations on seed growth. When the concentration meter detects that the mixture of the components in the mixing box 101 reaches the lowest preset concentration, the three-way valve 103 closes the water pump 106 and the dry air pipe 118, and the nutrient solution with the lowest concentration is injected into the nutrient solution temporary storage box 303 along the feed pipe 105 and the discharge end 2 under the action of the feed pump 104, and then the pump body flow meter at the bottom of the nutrient solution temporary storage box 303 injects a preset amount of nutrient solution into the culture tank 302;

[0047] After finishing the injection of liquid into the nutrient solution temporary storage tank 303, the three-way valve 103 closes the channel of the mixing tank 101 and opens the water suction pipe 106. At the same time, the micro-motor 113 drives the rotating baffle 115 to rotate on the surface of the hollow plate 112, so that after the rotating baffle 115 rotates, it just blocks the hollow part of the hollow plate 112. Then the feeding pump 104 extracts clean water inside the clean water chamber through the water suction pipe 106 and injects it into the feeding pipe 105. The clean water pushes the rotating baffle 115, the hollow plate 112, and the guiding roller 114 to move inside the feeding pipe 105, so that the rotating baffle 115 and the hollow plate 112 push the residual liquid to gather and move until the rotating baffle 115 and the hollow plate 112 pass over the control valve 116.

[0048] During the process of the rotating baffle 115 and the hollow plate 112 being pushed, the servo motor 109 drives the winding disc inside the winding box 110 to rotate to release the pull rope 111, so that the pull rope 111 is released synchronously with the movement of the micro-motor 113. Then the control valve 116 is opened. While the clean water pushes the rotating baffle 115 and the hollow plate 112 to move inside the feeding pipe 105, the inside of the feeding pipe 105 is flushed. The flushed water then returns to the inside of the return water chamber through the opened control valve 116 along the return water pipe 117 to wait for treatment. After the above operations are completed, the discharge end 2 injects the nutrient solution with increased concentration into the culture tank 302 at the next position. At this time, first, the concentration meter inside the previous nutrient solution temporary storage tank 303 determines the concentration of the nutrient solution injected last time, and then based on this concentration, each component is injected into the mixing tank 101 through the feed valve hose 102 until the nutrient solution prepared inside the mixing tank 101 reaches the concentration value required for the next culture tank 302. By moving the water tank 107 to move uniformly along the preset track, the discharge end 2 reaches the culture tank 302 at the next position.

[0049] During the movement, the control valve 116 is closed, the three-way valve 103 closes the water suction pipe 106 and the channel of the mixing tank 101, and opens the channel of the dry air pipe 118. At this time, the dry air pipe 118 injects dry air into the three-way valve 103, the feeding pump 104, and the feeding pipe 105 for air drying to prevent water stains from remaining and affecting the subsequent transmission of the nutrient solution. When reaching the culture tank 302 at the next position, the servo motor 109 drives the winding disc inside the winding box 110 to rotate to wind up the pull rope 111, so that the rotating baffle 115 and the hollow plate 112 move in the reverse direction to reset, and at the same time rotate to expose the hollow part on the surface of the hollow plate 112 for the subsequent transmission of the nutrient solution.
