Description

Technical Field

[0001] The utility model relates to the field of flower seedling raising and fertilizing management, in particular to a flower seedling raising and fertilizing management device. Background Art

[0002] Plug tray seedling cultivation is a mature advanced agricultural technology that has emerged with the rapid development of modern agriculture, the continuous improvement of agricultural scale management, specialized production, mechanization and automation. It is an advanced production method that uses scientific, mechanized, automated and other technical measures and means to mass produce high-quality flower seedlings under the best artificial environmental conditions. Compared with traditional seedling cultivation methods, plug tray seedling cultivation technology has the advantages of using less seeds and occupying less area; it can shorten the seedling age and save seedling cultivation time; it can minimize the occurrence of diseases and pests; it can improve seedling production efficiency and reduce costs; it is conducive to unified management and the promotion of new technologies, and it can achieve continuous production throughout the year.

[0003] During the seedling raising process, regular watering is required and the water content of the seedling raising soil should be monitored at any time. If drought occurs, it will seriously affect the growth and development of the seedlings.

[0004] During the transplanting process, the roots of some varieties of seedlings are more developed. The seedling matrix fits tightly with the wall of the seedling trough under the action of the seedling roots. The seedlings need to be pulled out with great force, which can easily damage the seedlings, increase the difficulty of transplanting, and reduce the speed of transplanting. If the seedlings are damaged, it will also affect the seedlings' growth. Since the nursery site is far from the transplanting site, the seedlings need to be transported. During transportation, the seedling matrix will shake and become loose. During transplanting, the roots of the seedlings are easily separated from the matrix. The seedlings without the matrix at the roots will grow slowly, while the seedlings with the matrix will grow quickly. The two seedlings grow in the same field, and the seedlings with slower growth will be suppressed by the surrounding seedlings, affecting their growth. Transplanting the two seedlings separately will greatly increase the difficulty of transplanting.

[0005] For example, for tulip seedling cultivation, the original tulip seedling cultivation technology is: 2,000 fertilizer balls per mu, use 400 kg of sandy loam, 100 kg of decomposed organic fertilizer, 20 kg of supercalcium, 100 kg of human and animal manure, and 0.1 kg of 50% carbendazim, mix well, ferment for a period of time, and rub into fertilizer balls of about 0.25 kg. Then put the prepared fertilizer balls on the seedbed, close to each other, leaving no gaps between the fertilizer balls, sow 3-5 flower seeds in each fertilizer ball, press the fertilizer ball into the fertilizer ball with your hand, cover it with sifted fine soil (just enough to cover the flower seeds), then water it to moisten the soil, and afterwards build an arch bridge on the seedbed with bamboo strips, cover the arch bridge with ground film to ensure the seedling temperature of the fertilizer ball. This method of raising seedlings requires not only preparing the seedbed in advance, but also pest control and moisture preservation. After sowing the seedlings, it is necessary to carry out moisture preservation and heat preservation management, and repeatedly open the ground film or set up straw curtains for sun protection. Both the pre-production and post-production maintenance of the fertilizer balls are relatively complicated and tedious, and require rich experience for the planting personnel. In addition, when using the same land area, the number of seedlings is limited, the planting amount is small, and the planting cost is high. On the other hand, when transplanting flower seedlings, the entire fertilizer ball must be shoveled up and transported to the flower field using a handling device for planting. In the process, the shape of the fertilizer ball is easily destroyed, resulting in damage to the seedlings and reducing the survival rate of transplanted flower seedlings. Utility Model Content

[0006] In view of the technical problems existing in the prior art, the utility model provides a flower seedling fertilization management device, which has a high planting land utilization rate and can realize automated fertilization management of flower seedlings, ensuring the germination rate of flower seeds. When transplanting flower seedlings, it can quickly transport and transplant the flower seedlings while protecting them, avoiding damage to the flower seedlings and ensuring the survival rate of the flower seedlings.

[0007] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0008] A flower seedling fertilization management device comprises a support frame, a central axis support is spanned between the support frames, a rotating shaft is sleeved on the central axis support, an outer frame for hanging seedling tray racks is provided on the rotating shaft, the outer frame is cylindrical, and a plurality of seedling tray racks are evenly suspended on the inner wall of the outer frame in a circumferential direction, a moisturizing nozzle facing the outer frame is provided on the support frame, a water and fertilizer pool containing nutrient solution is provided directly below the outer frame, and the support frame is provided with a driving mechanism at one end corresponding to the rotating shaft for driving the rotating shaft to rotate periodically according to a preset fertilization management method so that the bottoms of the plurality of seedling tray racks on the outer frame contact the nutrient solution in the water and fertilizer pool in turn.

[0009] Preferably, in the above-mentioned flower seedling fertilization management device, the seedling tray rack is composed of a universal shaft, a tray rack body, a water storage box and a counterweight block, the upper end of the tray rack body is connected to the inner wall of the outer frame through the universal shaft, a groove is provided on the lower bottom surface of the tray rack body, a seedling tray is placed in the groove, and a water filter hole is also provided on the lower bottom surface of the tray rack body, the water storage box is installed below the tray rack body, and holes are provided on the surrounding side walls of the water storage box, and the counterweight block is arranged at the lower bottom of the water storage box.

[0010] Preferably, in the above-mentioned flower seedling fertilization management device, the seedling tray is composed of a fertilizer ball frame and a base frame supporting the fertilizer ball frame, the bottom surface of the base frame is hollow, and a vertical top column is provided on the bottom surface thereof, the lower bottom surface of the fertilizer ball frame is formed by a cross combination of longitudinal and transverse bars, the upper end of the top column just fills the middle gap formed by the cross combination of longitudinal and transverse bars, a hook hung on the upper end of the base frame is provided on the upper top surface of the fertilizer ball frame, and there is a height difference between the lower bottom surface of the fertilizer ball frame and the lower bottom surface of the base frame.

[0011] When transplanting, the entire seedling tray can be directly removed and then carried to the planting field, saving the tedious operation of shoveling fertilizer balls one by one in the original planting method, and protecting the fertilizer balls from damage. In addition, the two-layer design of the seedling tray means that when the hook hanging on the fertilizer ball rack on the bottom frame is removed, the entire fertilizer ball rack will drop to fill the height difference, and then the top column facing the fertilizer ball will lift up the entire fertilizer ball. The planter can directly take the fertilizer ball with the flower seedlings and place it in the planting hole, eliminating the step of buckling the fertilizer ball from the fertilizer ball rack, effectively protecting the fertilizer ball from damage.

[0012] Preferably, in the above-mentioned flower seedling fertilization management device, the height difference between the lower bottom surface of the fertilizer ball rack and the lower bottom surface of the base frame is at least the vertical height of the top column, ensuring that when the top column is lifted up, two-thirds of the area of ​​the entire fertilizer ball is exposed in the middle gap of the fertilizer ball rack, which is convenient for manual picking and planting.

[0013] Preferably, in the above-mentioned flower seedling fertilization management device, the water storage capacity of the water and fertilizer pool at least ensures that the water in the water and fertilizer pool submerges the water storage box at the lowest point, so that the water storage box of each seedling tray rack can store water when passing by, and the fertilizer ball is prevented from being immersed in the water, so the water amount in the water and fertilizer pool must be strictly controlled.

[0014] Preferably, in the above-mentioned flower seedling fertilization management device, the sides of the fertilizer ball rack are inclined with respect to its lower bottom surface, and overlapping support rods for stacking the upper seedling trays are provided on the inner wall of the sides of the fertilizer ball rack, so as to facilitate the stacking of the seedling trays during transportation and improve the transportation efficiency.

[0015] Preferably, in the above-mentioned flower seedling fertilization management device, the height of the overlapping support rods from the bottom surface of the fertilizer ball rack is at least the height when the seedlings grow 4 tender leaves. Because it is generally best for the seedlings to grow four tender leaves when transplanting, it is necessary to ensure that the seedlings are not crushed when transporting the overlapping seedling trays.

[0016] Preferably, in the above-mentioned flower seedling raising and fertilizing management device, the moisturizing nozzle is connected to the water and fertilizer pool through a connecting pipe, and the water and fertilizer pool is connected to an automatic water supply pipe.

[0017] Preferably, in the above-mentioned flower seedling fertilization management device, the support frame is an inverted "mountain"-shaped structure, including a portal frame and a central column connected to the middle of the portal frame, the bottom of the portal frame and the central column are jointly supported on the ground, and the central axis bracket is connected to the upper part of the central column.

[0018] Preferably, in the above-mentioned flower seedling raising and fertilizing management device, the driving mechanism includes a servo motor fixed on the supporting frame and a reduction transmission gear fixed to one end of the rotating shaft and meshing with the servo motor.

[0019] The beneficial effects of the utility model are:

[0020] 1. Due to the structure of supporting the rotation of the outer frame, the seedling tray rack carried by the outer frame can be used to hang the seedling tray, so that more fertilizer balls can be placed to grow seedlings and flower seedlings in the smallest area. The rotating outer frame can lower the high seedling tray rack to facilitate seedling management and observation and collection.

[0021] 2. Since a moisturizing nozzle is provided on the outer frame, water spray can be performed on the top of the seedling tray to ensure the air humidity and targeted moisturizing. In addition, the water and fertilizer pool under the outer frame can allow the rotating water storage box to automatically add a certain amount of water or nutrient solution to ensure that steam floats at the bottom of the fertilizer ball in the seedling tray to ensure the moisture inside the fertilizer ball. The combination of the moisturizing nozzle, water and fertilizer pool and water storage box can fully ensure the humidity of the air inside and around the fertilizer ball, thereby improving the germination rate of seedlings.

[0022] 3. Since the seedling tray rack is suspended on the inner wall of the outer frame, the design of the counterweight block can ensure that the seedling tray rack is always in the correct position when the outer frame rotates, avoiding the seedling tray rack from tilting and overturning the fertilizer ball in the seedling tray. The universal shaft ensures that the seedling tray rack is always in a balanced position under the gravity pull of the counterweight block. This structural design is convenient for operation when placing the seedling tray, maintaining the fertilizer ball, and taking the seedling tray.

[0023] 4. Since there are multiple water filtering holes on the water storage box, and the lower bottom surface of the tray body can also filter water, excess water can be discharged from the water storage box after passing through the water and fertilizer pool to prevent excessive water in the fertilizer ball from killing the seedlings. The small amount of water remaining at the bottom of the water storage box can also evaporate slowly to ensure that the bottom of the fertilizer ball is moist, strictly control the amount of water applied to the fertilizer ball, and ensure the germination rate of flower seeds and the survival rate of seedlings.

[0028] In order to further understand the present invention, the present invention is further described below with reference to the accompanying drawings and specific embodiments:

[0029] In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, the embodiment of the utility model proposes a flower seedling fertilization management device, which includes a support frame 1, a central axis support 2 spanning between the support frames 1, a rotating shaft 3 sleeved on the central axis support 2, and an outer frame 4 for hanging a seedling tray 5 on the rotating shaft 3. Figure 1 and Figure 2 As shown, the outer frame 4 is composed of circular frames 41 at the left and right ends and a plurality of crossbars 42 between the two circular frames 41. To ensure strength, a reinforcing rod 43 is also set between the circular frame 41 and the rotating shaft 3. One or more seedling trays 5 are hung on each crossbar 42. In the embodiment of the utility model, three seedling trays 5 are hung on one crossbar 42, which is both reasonably constructed and designed in consideration of the bearing capacity of the outer frame 4. Figure 1 As shown, a moisturizing nozzle 6 is provided on the support frame 1 facing the outer frame 4, and a water fertilizer pool 7 containing nutrient solution is provided directly below the outer frame 4. The water fertilizer pool 7 can also be filled with only clean water for seedling moisturizing. In order to realize automated fertilization management, Figure 1 As shown, the support frame 1 is provided with a driving mechanism 9 at one end corresponding to the rotating shaft 3, and the driving mechanism 9 is used to drive the rotating shaft 3 to rotate regularly, and the preset program instructions for the regular rotation are formulated according to the preset fertilization management method. For example, in a certain humidity environment, depending on the type of flower seedlings, a rotation is performed with a corresponding number of days as a cycle, and a rotation of 360° is performed once, that is, the outer frame 4 rotates one circle at a time. Through this rotation, the bottoms of the multiple seedling trays 5 on the outer frame 4 are contacted with the nutrient solution in the water and fertilizer pool 7 in turn, thereby realizing regular automatic fertilization management, reducing the labor cost of seedling fertilization, and improving the accuracy of fertilization control during large-scale flower seedling cultivation.

[0032] Further, in a preferred embodiment of the present invention, Figure 3As shown, the seedling tray frame 5 is composed of a universal shaft 51, a tray frame body 52, a water storage box 53 and a counterweight 54, wherein the upper end of the tray frame body 52 is connected to the cross bar 42 of the outer frame 4 through the universal shaft 51, and the lower bottom surface of the tray frame body 52 is provided with a groove, in which the seedling tray 8 is placed. A water filter hole 55 is also provided on the lower bottom surface of the tray frame body 52, and the water storage box 53 is installed below the tray frame body 52, and holes 531 are provided on the surrounding side walls of the water storage box 53. The counterweight 54 is arranged at the lower bottom of the water storage box 53. The function of the counterweight 54 is to keep the seedling tray frame 5 in a horizontal state regardless of how the outer frame 4 rotates, so as to prevent the seedling tray 8 from tipping over or the fertilizer mass in the tray from pouring out when the outer frame 4 is manually rotated to check the seedling tray 8. The water storage capacity of the water and fertilizer pool 7 at least ensures that the water in the water and fertilizer pool 7 submerges the lowest water storage box 53. Whenever water penetrates into the water and fertilizer pool from the water storage box 53, the water can pass through the hole 531-water filter hole 55 to soak and moisturize the bottom of the seedling tray 8. After lifting the entire seedling tray frame 5, excess water can be discharged along the original route to avoid accumulation in the water storage box 53, resulting in excessive water at the bottom of the seedling tray 8, affecting the germination of flower seeds and the growth of flower seedlings.

[0033] Further, in a preferred embodiment of the present invention, Figure 3 As shown, the seedling tray 8 is composed of a fertilizer ball frame 81 and a bottom plate frame 82 carrying the fertilizer ball frame 81, wherein the bottom surface of the bottom plate frame 82 is hollowed out, and a vertical top column 83 is provided on its bottom surface. The lower bottom surface of the fertilizer ball frame 81 is formed by the cross combination of longitudinal and transverse bars, and the upper end of the top column 83 just fills the middle gap formed by the cross combination of longitudinal and transverse bars. A hook 84 is provided on the upper top surface of the fertilizer ball frame 81 and is suspended from the upper end of the bottom plate frame 82. The hook 84 is rotatable (hinge connection mode), which is convenient for the entire fertilizer ball frame 81 to fall smoothly after rotation. There is a height difference between the lower bottom surface of the fertilizer ball frame 81 and the lower bottom surface of the bottom plate frame 82. The height difference between the lower bottom surface of the fertilizer ball frame 81 and the lower bottom surface of the bottom plate frame 82 is at least the vertical height of the top column 83.

[0034] Specifically, in the preferred embodiment of the present utility model, Figure 3 As shown, the side of the fertilizer rack 81 is inclined with its lower bottom surface, and an overlapping support rod 85 for stacking the upper seedling tray 8 is provided on the inner wall of the side of the fertilizer rack 81. The height of the overlapping support rod 85 from the lower bottom surface of the fertilizer rack 81 is at least the height of the seedling growing four leaves, so that when the seedling tray 8 is transported, the upper overlapping seedling tray 8 will not press down on the seedling, which facilitates the efficient transportation of the overlapping seedling tray 8.

[0035] like Figure 1As shown, the moisturizing nozzle 6 is connected to the water and fertilizer pool 7 through a connecting pipe, and can also be connected to other water supply pipes or nutrient solution boxes. The water and fertilizer pool 7 is connected with an automatic water supply pipe, which automatically stores water or drains water. When moisturizing is needed, the outer frame 4 is manually rotated to allow each water storage box 53 to pass through the water and fertilizer pool 7 once, fill the water storage box 53, and moisturize the fertilizer from the bottom of the fertilizer ball. A liquid level sensor is provided in the water and fertilizer pool 7. After the liquid level sensor senses that the water and fertilizer liquid level in the water and fertilizer pool 7 is lower than the preset height position, the automatic water supply pipe starts to supply water until the water and fertilizer liquid level rises to the preset maximum water level.

[0036] When in use, the rolled seedling fertilizer balls are placed one by one in the seedling tray, and then the seedling tray 8 is carried to the greenhouse and hung in the seedling tray frame 5. In the later management, the moisture-retaining nozzle can be used to blow water vapor to the fertilizer balls, and the driving mechanism 9 can also drive the rotating outer frame 4 to transfer each seedling tray frame 5 on the cross bar 42 into the water fertilizer pool 7 one by one, and then transfer out. It should be noted that when the outer frame 4 stops at the end, it is prevented that one of the seedling tray frames 5 stays in the water fertilizer pool 7 to prevent the seedlings from drowning. The residence time of the seedling tray frame 5 passing through the water fertilizer pool 7 is set to 30 to 60 seconds. When transplanting, rotate the outer frame 4, take down the seedling trays 8 one by one, then overlap the seedling trays 8 and carry them to the planting field. When it is necessary to take out the fertilizer ball with the seedlings, rotate the hook 84 to let the fertilizer ball frame 81 of the seedling tray 8 automatically fall down, and the top column 83 pushes the fertilizer ball out. After it is pushed out, the planter directly takes the fertilizer ball with the seedlings and puts it in the planting hole, and finally covers it with soil and waters it.

[0037] Further, in a preferred embodiment of the present invention, Figure 1 As shown, the support frame 1 is an inverted "mountain" shaped structure, including a gantry frame 11 and a center column 12 connected to the middle of the gantry frame 11. The bottoms of the gantry frame 11 and the center column 12 are jointly supported on the ground, and the center axis bracket 2 is connected to the upper part of the center column 12. The driving mechanism 9 includes a servo motor fixed to the support frame 1 and a reduction transmission gear fixed to one end of the rotating shaft 3 and meshing with the servo motor. Furthermore, in order to facilitate manual operation to rotate the outer frame 4, a disengageable meshing transmission connection is adopted between the driving mechanism 9 and the rotating shaft 3. The reduction transmission gear is connected to the rotating shaft 3 through a disengageable coupling. In daily automatic fertilization management, the disengageable coupling maintains a linkage connection with the rotating shaft 3. At this time, the servo motor can drive the rotating shaft 3 to complete the rotation by driving the reduction transmission gear. When the outer frame 4 needs to be manually operated in the later stage, the disengageable coupling is adjusted to the clutch state from the rotating shaft 3, and the outer frame 4 can be manually operated to rotate. Since the disengageable coupling and the rotating shaft 3 are in the clutch state at this time, when the outer frame 4 is manually operated to rotate, the reduction transmission gear does not interfere with the outer frame 4.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and the specification only describe the principle of the utility model. The utility model may have various changes and improvements without departing from the spirit and scope of the utility model, and these changes and improvements fall within the scope of the utility model to be protected, and the scope of protection required by the utility model is defined by the attached claims and their equivalents.
