In some embodiments, the control system is further provided with an alarm unit electrically connected with the central control unit, and when the central control unit monitors that the number of the seedling trays 400 which do not reach the standard reaches a certain number, the alarm unit is controlled to give an alarm to remind a worker to check the batch of seedling trays 400 and the cultivation equipment.
The control method comprises the following specific steps:
s1, numbering the seedling raising trays 400 entering the spiral tower, and recording in a central control unit;
s2, in the cultivation process, the weight, the moisture content and the plant growth condition of the seedling raising tray 400 are monitored through a monitoring unit, information is fed back to a central control unit for recording and storage, and the central control unit controls a cultivation system to adjust irrigation and illumination intensity of plants in the seedling raising tray according to the fed back information;
s3, observing the seedling raising tray 400 reaching the blanking position through a monitoring unit, recording the numbers of the seedling raising tray 400 with the unqualified growth condition in a central control unit, and calling the records of the seedling raising tray 400 for analysis.
In some embodiments, the structure of the seedling tray 400 is uniquely designed for seed cultivation, and the cultivation control method is improved for the unique structure of the seedling tray 400. As shown in fig. 5 and 6, the seedling raising tray 400 has a tray 410 as a main body, and a side wall 420 extending along the circumferential direction of the tray 410 and enclosing a circle is provided at the edge of the tray 410. The tray 410 has a plurality of grooves 460 for catching seeds at the inner side of the bottom, the grooves 460 are generally square holes or circular holes, the radius or side length is generally 0.5-1mm, the opening thereof is gradually reduced from top to bottom, and the inner side surface of the grooves 460 is in a circular arc structure. The uppermost end of the groove 460 has a diameter or width smaller than the maximum diameter of the seed in the height direction when the seed is normally placed in the groove 460, thereby enabling the seed to be smoothly caught in the groove 460. Meanwhile, the depth of the groove 460 needs to meet the requirement that when the seeds are clamped in the groove 460, a certain gap is reserved between the lower ends of the seeds and the bottom of the groove 460, so that ventilation effect below the seeds is guaranteed, and a part of nutrient solution can be stored in the groove 460, so that the lower parts of the seeds are soaked in the nutrient solution or are not soaked in the nutrient solution, but the seeds are in a moist and nutrient-sufficient environment in the groove 460, and the phenomenon of bud rot can not occur while the sufficient nutrient supply of the seeds is guaranteed. The bottom of the seedling tray 400 is provided with a drain hole 430, and excessive water and nutrient solution in the seedling tray 400 can flow out through the drain hole 430.
This can make the operation extremely cumbersome and time consuming if a suitable amount of nutrient solution is added to each recess 460 separately. If some highly technical equipment is used to realize the automatic addition of the nutrient solution, on the one hand, the delay of a process for a long time is avoided, and on the other hand, the cost is greatly increased.
In this embodiment, by combining the drain hole 430 with the groove 460, when the cultivating device pours the nutrient solution into the tray 410, the nutrient solution initially flows over the upper end of the seeds and stays in the tray 410, and is slowly drained into the water receiving tank 500 through the drain hole 430. Meanwhile, since the seeds are stuck on the upper side of the groove 460 and the shape of the seeds is not completely consistent with that of the groove 460, gaps exist between the seeds and the groove 460, and at this time, the nutrient solution can slowly permeate into the groove 460 through the gaps between the seeds and the groove 460 and be stored on the lower side of the groove 4603. By controlling the size of the drain hole 430 and the single pouring amount of the nutrient solution, the time that the single poured nutrient solution stays at the bottom of the tray 410 can be effectively controlled, so that the amount of the nutrient solution stored in the groove 460 is controlled, and the effect that the lower part of the seed is soaked in the nutrient solution or is not soaked in the nutrient solution, but the seed is in a moist and nutrient-rich environment in the groove 460, and the bud rot phenomenon is not generated while the sufficient nutrient supply of the seed is ensured is achieved.
In addition, through setting up a plurality of recesses 460 at equidistant in tray 410, after the seed germination growth in the recess 460, its root system can be around the circumference growth of recess 460, and because the interval between the adjacent recess 460 is less, generally 0.5-1.5mm for most root system can twine together, does benefit to whole dish and takes out when the results, has avoided the emergence of the circumstances such as some finished products scatter, has solved seedling tray 400 root system and has rolled up because of the lack of water causes the problem of batching, is unfavorable for agglomerating.
When the seedling raising tray 400 adopts the above structure, the concrete operation of irrigation in step S2 is as follows: during irrigation, the central control unit analyzes the time that the fluid needs to stay in the seedling tray 400 according to the information fed back by the monitoring unit, judges the water level height required by irrigation in the seedling tray 400 according to the sizes of the seedling tray 400 and the drain holes 430, and stops irrigation after the sensing device senses that the water level in the seedling tray 400 reaches the required height.
By the cultivation control method, the cultivation process of the seedling raising tray in the spiral tower can be monitored and regulated in real time systematically and completely, and a matched irrigation method is designed according to the unique structure of the seedling raising tray 400, so that the production efficiency and the cultivation effect on seedlings and seeds are effectively improved.
In some embodiments, the tray delivery system is modified to accommodate the drainage design of tray 400. As shown in fig. 3 to 5, the seedling tray conveying system mainly includes a cart 200 and a cart driving assembly 300. The carriage driving unit 300 includes a chain guide 310 which is disposed inside the rail 100 in correspondence with the extending direction of the rail 100, a chain 320 disposed in the guide, and a chain driving mechanism 330 which drives the movement of the chain 320. The chain driving mechanism 330 comprises a motor 341 arranged at the bottom of the tower body, a main shaft 342 connected with the output shaft of the motor 341 in a transmission way, and a gear sleeved on the main shaft 342. Specifically, the chain guide 310 has a notch near the main shaft 342 into which the gear extends to engage the chain 320, i.e., only a portion of the tooth near the chain engages the chain 320. When the motor 341 controls the spindle 342 to rotate, the gear rotates to drive the chain 320 to move along the track 100. In some embodiments, two chain driving mechanisms 340 are disposed on each tower, and the number and positions of the gears sleeved on the main shaft 342 correspond to the number of layers of the tower, that is, the chain of each layer of tower has a set of meshed gears.
The cart 200 includes a support plate 220 and a connection plate 210, one side of the connection plate 210 is detachably connected to a chain 320, and the other side is fixedly connected to the support plate 220. In some embodiments, a plurality of protrusions 330 extending above the chain guide rail 310 are arranged on the chain 320 at intervals, and a matching through hole is arranged on the connecting plate 210, and the protrusions 330 pass through the through hole so that the trolley 200 can synchronously move along with the chain 320. In order to prevent the connection plate 210 from rotating along the protrusion 330 to affect the stable transportation of the cart 200 to the seedling tray 400, the connection plate 210 is provided with at least two through holes corresponding to the protrusion 330.
In some embodiments, the pulley guide rail 110 is installed at the outer side of the rail 100 in the same direction as the rail 100 extends, and the directional pulley 230 installed in the pulley guide rail 110 is installed at a position below the support plate 220 at the outer side of the rail 100, so that friction between the trolley 200 and the rail 100 can be reduced, and abrasion of the trolley 200 and the rail 100 can be reduced.
In some embodiments, the outside of the track 100 is provided with a water receiving groove 500 in line with the extending direction of the track 100, and the height of the chain guide 310 is higher than the height of the directional pulley 230. When the cart 200 is on the rail 100, the upper end surface of the support plate 220 is a slope with a height gradually decreasing from the inside of the rail 100 to the outside of the rail 100, and thus the seedling tray 400 placed on the support plate 220 is also in an inclined state. Meanwhile, the drain hole 430 is provided at one side of the bottom of the seedling tray 400, and the drain hole 430 is located outside the rail 100 when the seedling tray 400 is placed on the support plate 220. In some embodiments, the upper side of the track 100 of the chain 320 is provided with a pad, and the height of the connection plate 210 can be adjusted by setting the thickness and number of the pad, so as to adjust the inclination of the support plate 220, and typically, the inclination of the support plate 220 is 1-3 degrees. By means of the arrangement, redundant water or nutrient solution in the seedling raising tray 400 can flow to the outer side of the track 100, flow into the water receiving tank 500 through the water drain holes 430 and flow into corresponding recovery equipment along the water receiving tank 500, so that recovery of the water and the nutrient solution is achieved, resources are saved, and influence on the surrounding environment and the operation of a conveying system due to the fact that the water or the nutrient solution flows around the track 100 is avoided.
In order to ensure uniform permeation rate of the nutrient solution into each groove 460 by matching the positions of the water receiving groove 500 and the water discharging hole 430, and considering the flow direction of the nutrient solution in the tray 410, the fluid supply unit pours the nutrient solution into the tray 410 from the side of the tray 410 away from the water discharging hole 430, so that the residence time of the nutrient solution in each position in the tray 410 is approximately the same when the nutrient solution flows in the tray 410, and uniform permeation into the grooves 460 is maintained. Meanwhile, the diameter of the cultivated seeds needs to be primarily screened, so that the sizes of the same batch of seeds are kept consistent as much as possible, and the gap between the seeds and the groove 460 is smaller when the seeds are clamped in the groove 460. The nutrient solution herein includes water and the rest of the prepared liquid for culturing seeds.
It should be noted that, the design of the water receiving tank 500 fully considers the spiral structure of the tower body, and the seedling tray guides water and nutrient solution, so that the structure of the seedling tray conveying system is fully utilized. Particularly, the protrusion 330 is matched with the through hole on the connecting plate 210, so that when the height of the cushion block or the chain guide rail 310 is adjusted, the protrusion 330 can freely stretch and retract in the through hole, and the inclination of the supporting plate 220 is adjusted. The drainage structure of the embodiment does not have excessive useless configuration on the basis of the seedling tray conveying system, has very ingenious design thought and structure, simplifies the structure and the installation difficulty of the water planting equipment as much as possible while realizing the functions, and saves the cost.
In addition, in order to enhance the structural strength of the seedling raising tray 400, reinforcing ribs 440 are provided on the outer side surface of the seedling raising tray 400. The reinforcing ribs 440 form a crisscross net structure at the outer side of the bottom of the tray 410, and form a pit 450 with a fixed shape at the middle of the outer side of the bottom of the tray 410, the pit 450 has a square cross section, a triangle cross section and other straight-sided figures, and the upper side of the supporting plate 220 is provided with matched convex blocks. Through the block of pit 450 and lug, make seedling tray 400 can place on dolly 200 steadily, can not take place to remove for fluid supply system can accurately water in to seedling tray 400, and unnecessary water and nutrient solution also can accurately follow the inclined plane of backup pad 220 and flow to water receiving tank 500. Meanwhile, due to the presence of the reinforcing ribs 440, a certain gap is formed between the bottom of the tray 410 and the support plate 220, so that water and nutrient solution can more conveniently flow out of the drain holes 430. In some embodiments, the drain holes 430 are disposed at the edge of the bottom of the tray 410, and the ribs 440 are not disposed at the edge of the bottom of the tray 410, so that the excessive water and nutrient solution can smoothly flow into the water receiving tank 500 without being blocked.
When the hydroponic apparatus works, the seedling tray 400 is placed above the trolley 200, and the connecting plate 210 is directly sleeved on the protrusion 330 of the chain 320, so that the trolley 200 is fixed on the chain 320. The chain driving mechanism works to drive the trolley 200 to move along the spiral track 100, and in the process, the fluid supply system, the illumination system and the ventilation system work to provide nutrient solution, water, illumination and the like required by growth for seeds or seedlings in the seedling raising tray 400. The moving speed of the chain 320 is controlled so that the cart 200 moves on the rail 100 for a sufficient time to complete the cultivation of seeds or seedlings. When the cart 200 moves to the blanking area 130, the protrusions 330 of the chain 320 are separated from the connection plates 210 only by lifting the cart 200 upward by a device or moving the chain 320 downward from the end of the chain guide 310, i.e., the cart 200 with the seedling tray 400 is separated from the rail 100. Similarly, the mounting of the trolley 200 on the track 100 can be achieved by only sleeving the through holes on the connecting plate 210 of the trolley 200 into the protrusions 330 of the chain 320 at the feeding area 120.
When the trolley is in operation, the chain guide rail 310 controls the extending direction of the chain 320, and then the trolley 200 is installed on the chain 320, so that synchronous movement control of all the trolleys 200 on the track 100 can be completed by driving the chain 320, and the trolley 200 cannot slide on the inclined track 100. By the fast detachable mounting mode of the protrusions 330 and the through holes, the trolley 200 can be rapidly mounted on and detached from the chain 320, the phenomenon that the chain 320 is blocked due to the mounting component is avoided, and the loading and unloading control of the trolley 200 is conveniently realized. Therefore, the seedling tray conveying system provides great convenience for controlling the cultivation process of the whole equipment.
