Description

Technical Field

[0001] The invention relates to the field of hydroponic transplanting, and in particular to a device for transplanting agricultural planting and cultivating seedlings. Background Art

[0002] Agricultural planting seedling transplanting equipment is a device used to transfer seedlings cultivated in a nursery room to a hydroponic environment for subsequent growth. It is one of the mechanized agricultural equipment.

[0003] In the traditional seedling raising process, the seedling raising tray has a relatively single function and is only applicable to the seedling raising room environment. It is impossible to conveniently transfer from the seedling raising room to the hydroponic machine for direct hydroponics. This makes the transition process of seedlings from seedling raising to hydroponics extremely cumbersome. The seedlings are often required to be carefully removed from the seedling raising tray manually and then relocated to the specific bearing structure of the hydroponic equipment. The existing manual process of removing the seedlings from the seedling raising tray and then carrying out hydroponic cultivation will cause damage to the part where the roots of the seedlings are bonded to the seedling raising tray. Secondly, in the existing seedling raising device, when the seedlings are transferred from the seedling raising environment to the hydroponic environment, it is difficult to accurately control the degree of contact between the seedlings and the nutrient solution. It is often the case that the roots of the seedlings cannot be fully immersed in the nutrient solution, resulting in insufficient nutrient absorption, affecting the growth trend, or the seedlings are completely separated from the bearing structure and fall into the nutrient solution due to improper operation, causing damage or even death.

[0004] In the process of transitioning from traditional seedling cultivation to hydroponics, certain impurities will be generated when the seedlings are transferred from the seedling room to the hydroponic machine. However, the existing equipment lacks an effective cleaning mechanism. These impurities adhere to the seedlings, hindering nutrient absorption and causing diseases and insect pests. Manual cleaning of impurities is not only extremely inefficient, but can also easily cause physical damage to the fragile seedlings due to improper operation.

[0005] In existing hydroponic equipment, during the rapid growth stage of the seedlings in the hydroponic machine, as the seedlings grow, their stems are soft and can easily become entangled with each other in a limited space, which not only affects lighting and ventilation, hinders photosynthesis and gas exchange, but also leads to uneven nutrient distribution, causing some seedlings to grow poorly or even die. At the same time, due to the lack of a reliable straightening mechanism, the seedlings are prone to grow crookedly, affecting the plant morphology and subsequent yield. Although manual intervention can temporarily solve the problem, frequent operations can easily damage the plants and are inefficient.

[0006] Therefore, it is necessary to provide an agricultural planting and cultivation seedling transplanting equipment to solve the above problems. Summary of the invention

[0007] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an agricultural planting and cultivation seedling transplanting equipment.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an agricultural planting and seedling transplanting equipment, comprising a hydroponic machine housing, a nutrient solution pool and a water pump, wherein a plurality of the nutrient solution pools are arranged on the hydroponic machine housing, the water pump is installed at the bottom of the hydroponic machine housing, and a gap increasing component is arranged on the top of the nutrient solution pool;

[0009] The gap increasing assembly includes a plurality of connecting plates clamped on top of each nutrient solution pool, a first return spring is fixedly connected between every two of the connecting plates, two groups of arc blocks are symmetrically fixedly connected to the top of each nutrient solution pool, and each group of arc blocks is provided with four, a trapezoidal slider is symmetrically fixedly connected to the outer wall of the nutrient solution pool, and a strip groove and a hemispherical groove are provided on the side of the trapezoidal slider away from the nutrient solution pool.

[0010] Preferably, the gap increasing component also includes a trapezoidal slide groove, which is symmetrically opened on the inner wall of the hydroponic machine housing, and the trapezoidal slide groove is evenly distributed and provided with three groups, and the interior of the trapezoidal slide groove is symmetrically and evenly distributed with four spring clamping balls fixedly connected, and the spring clamping balls are provided with three groups.

[0011] Preferably, a driving assembly is provided under each of the nutrient solution pools, and the driving assembly includes a plurality of positioning plates, and the plurality of positioning plates are fixedly connected to the inner wall of the hydroponic machine housing, and the top of each positioning plate is fixedly connected to a second return spring, and the end of the second return spring away from the positioning plate is fixedly connected to a water collecting tank.

[0012] Preferably, a seedling supporting assembly is provided on the hydroponic machine housing, and the seedling supporting assembly includes multiple groups of vertical grooves, and the multiple groups of vertical grooves are all opened on the hydroponic machine housing, and each group of the vertical grooves is opened with three, and each group of the vertical grooves is slidably connected with a double-layer slide plate, and the outer wall of each double-layer slide plate is fixedly connected with three cross limiting plates, and each of the cross limiting plates is slidably connected with a telescopic block in an upper and lower symmetrical manner.

[0013] Preferably, a servo motor is installed on the top of the hydroponic machine housing, and a threaded rod is fixedly connected to the output shaft of the servo motor.

[0014] Preferably, the adjacent sides of every two connecting plates are configured to be arc-shaped, and each of the arc-shaped blocks is located at the connection between every two connecting plates.

[0015] Preferably, the trapezoidal sliding block is slidably connected to the inside of the trapezoidal sliding groove, and both the strip groove and the hemispherical groove are matched with the spring clamping ball.

[0016] Preferably, the trapezoidal sliding block is interference fit with the trapezoidal sliding groove.

[0017] Preferably, the threaded rod is threadably matched with each double-layer slide plate.

[0018] Preferably, the cross limiting plates and the telescopic blocks are equidistantly distributed above the connecting plate.

[0019] The agricultural planting and seedling transplanting equipment provided by the present invention has the following beneficial effects compared with the prior art:

[0020] The seedling tray can be directly used on the hydroponic machine. There is no need to take the seedlings out of the seedling tray after raising them. The roots of the seedlings entangled or adhered to the seedling tray will not be damaged when taking out the seedlings, thereby increasing the survival rate of the seedlings in hydroponics.

[0021] At the same time, the seedling tray can be directly used in the environment of the seedling room and the hydroponic machine, so that the seedling tray can be directly installed on the hydroponic machine after being moved out of the seedling room, avoiding damage to the roots of the seedlings caused by taking and placing the seedlings during the process of transplanting from the seedling room to the hydroponic machine, and improving the convenience and reliability of seedling to hydroponic cultivation.

[0022] The invention solves the problem that the existing hydroponic equipment cannot automatically adjust the contact depth between the seedlings and the nutrient solution. When the seedling tray is installed on the hydroponic machine, the seedlings will automatically slide along the seedling tray for a certain distance without falling off completely, thereby ensuring that the roots of the seedlings can penetrate deeply into the nutrient solution, fully absorb nutrients and promote growth.

[0023] Under the action of vibration, impurities carried on the seedlings during the seedling cultivation period will automatically fall into the nutrient solution pool. During the installation of the culture tray, vibration is used to automatically clean the impurities inside the seedlings, which not only avoids the interference of impurities on the growth of the seedlings, but also reduces the risk of damage to the seedlings, and improves the overall quality and efficiency of hydroponic seedlings.

[0024] It solves the problem of mutual entanglement in the early stage of growth of the cultivated seedlings, ensures that each cultivated seedling has independent growth space, and ensures reasonable distribution of space. At the same time, it plays a role in straightening the cultivated seedlings, making them grow upright and shaping a good plant shape. When the cultivated seedlings grow taller, it continues to provide support and restriction for the cultivated seedlings, adapt to the needs of different growth stages, reduce the risk of plant damage, improve the growth quality and management efficiency of the cultivated seedlings, and ensure the healthy and orderly growth of the cultivated seedlings.

The spring clamping balls 28 are composed of a spring and a spherical limiting block. This structure is a prior art and will not be elaborated on.

[0049] A driving assembly is provided under each nutrient solution pool 12, and the driving assembly includes a plurality of positioning plates 31, and the plurality of positioning plates 31 are fixedly connected to the inner wall of the hydroponic machine housing 11, and each positioning plate 31 is located under the connecting plate 21, and a second return spring 32 is fixedly connected to the top of each positioning plate 31, and there are eight second return springs 32 distributed in a rectangular shape, and one end of the second return spring 32 away from the positioning plate 31 is fixedly connected to a water collecting tank 33.

[0050] like Figures 9 to 13 As shown, a seedling supporting assembly is provided on the hydroponic machine housing 11, and the seedling supporting assembly includes multiple groups of vertical grooves 41, and the multiple groups of vertical grooves 41 are all opened on the hydroponic machine housing 11, and each group of vertical grooves 41 is opened with three, and a double-layer slide plate 42 is slidably connected in each group of vertical grooves 41, and the outer wall of each double-layer slide plate 42 is fixedly connected with three cross limit plates 43, and the cross limit plates 43 correspond to the vertical grooves 41, and each cross limit plate 43 is symmetrically slidably connected with a telescopic block 44 in an upper and lower manner, and the cross limit plates 43 and the telescopic blocks 44 slide horizontally, and the cross limit plates 43 and the telescopic blocks 44 are equidistantly distributed above the connecting plate 21, and a servo motor 45 is installed on the top of the hydroponic machine housing 11, and a threaded rod 46 is fixedly connected to the output shaft of the servo motor 45, and the threaded rod 46 is threadedly matched with each double-layer slide plate 42.

[0051] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows:

[0052] Working principle:

[0053] In the initial state, each trapezoidal slider 24 is located at the top of each strip groove 25, the first return spring 22 is not stretched, the second return spring 32 is not compressed, the nutrient solution pool 12 does not conflict with the water collection tank 33, and each set of double-layer slide plates 42 is located at the bottom of the vertical groove 41.

[0054] During operation, the seedlings are usually grown in the nursery room through the connecting plate 21, and when the seedlings grow to a size that can be transplanted, the seedlings and the connecting plate 21 are synchronously transferred to the hydroponic machine;

[0055] Then the staff placed the connecting plate 21 and the cultivated seedlings on the top of the nutrient solution pool 12. Since the adjacent sides of each two connecting plates 21 are set to an arc shape, the connecting parts of the two connecting plates 21 on one side are first pressed toward the arc block 23, and then the two connecting plates 21 are moved in a direction relatively away from the arc block 23. Since the connection interval between each two connecting plates 21 is smaller than the interval between each two arc blocks 23, during the process of one connecting plate 21 moving toward the other arc block 23, the connection part of the connecting plate 21 and the other connecting plate 21 is just located above the other arc block 23, so that when each two connecting plates 21 are plugged into the two sides of the arc block 23, the movement of the connecting plate 21 makes the connection part of each two connecting plates 21 located above the arc block 23, and then the two connecting plates 21 are connected to the arc block 23 one by one;

[0056] The length of the multiple connecting plates 21 is equal to the length of the nutrient solution pool 12. When the staff inserts each two connecting plates 21 on both sides of the arc block 23, the connecting plates 21 are fixed on the top of the nutrient solution pool 12 in sequence.

[0057] After the connecting plate 21 is placed on the top of the nutrient solution tank 12, the arc block 23 contacts the gap between every two connecting plates 21, thereby gradually stretching the first return spring 22 inside every two connecting plates 21, so that the gap between every two connecting plates 21 gradually increases;

[0058] Because the gap between every two connecting plates 21 gradually increases, the cultivated seedlings between the connecting plates 21 will slide a certain distance into the nutrient solution pool 12. Therefore, the gap between every two connecting plates 21 is smaller than the diameter of the cultivated seedlings, and the cultivated seedlings will not completely slide into the nutrient solution pool 12, but will only slide a certain distance to the bottom of the connecting plates 21, so that the roots move downward, which is convenient for the subsequent cultivated seedlings to contact with the nutrient solution inside the nutrient solution pool 12, solving the problem that the entangled roots cannot contact with the nutrient solution when cultivated in the seedling tray;

[0059] Then the staff continues to press the connecting plate 21, driving the nutrient solution pool 12 to slide down through the connecting plate 21, and then the nutrient solution pool 12 drives the trapezoidal sliders 24 on both sides to fall synchronously, at this time, the trapezoidal sliders 24 descend along the inner level of the trapezoidal slide groove 27, and at the same time, the trapezoidal sliders 24 gradually collide with the spring ball 28 through the hemispherical groove 26;

[0060] Furthermore, when the trapezoidal slider 24 slides down the trapezoidal slide groove 27, the trapezoidal slider 24 and the trapezoidal slide groove 27 have an interference fit, which increases the movement resistance of the trapezoidal slider 24. At the same time, the trapezoidal slider 24 continuously contacts the spring clamping ball 28 through the hemispherical groove 26, and the spring clamping ball 28 also generates resistance to the hemispherical groove 26. At the same time, when the hemispherical groove 26 and the spring clamping ball 28 are engaged, the movement of the trapezoidal slider 24 is hindered and interfered. At the same time, this engagement action causes the trapezoidal slider 24 to produce a momentary pause or speed change during the movement, thereby causing the trapezoidal slider 24 to vibrate.

[0061] At the same time, when the staff continues to press the connecting plate 21, the nutrient solution pool 12 will gradually contact the water collecting tank 33, and then the nutrient solution pool 12 will drive the water collecting tank 33 to gradually compress the second return spring 32 toward the positioning plate 31;

[0062] Since there are eight second return springs 32 distributed in a rectangular shape, and the surfaces of the nutrient solution pool 12 that conflict with the water collection tank 33 are both flat, the force of the nutrient solution pool 12 squeezing the water collection tank 33 will be dispersed in a rectangular shape, thereby preventing the water collection tank 33 from tilting during the descent process;

[0063] After the bottom of the water collecting tank 33 contacts the positioning plate 31, the staff can no longer press the connecting plate 21 and the nutrient solution pool 12, and the staff stops pressing, and then the second return spring 32 elastically stretches to push the water collecting tank 33 and the nutrient solution pool 12 to rise;

[0064] During the rising process of the nutrient solution pool 12, the nutrient solution pool 12 will drive the trapezoidal slider 24 to slide upward along the inside of the trapezoidal slide groove 27. Similar to the above-mentioned movement process, when the trapezoidal slider 24 continues to contact the spring ball 28 through the hemispherical groove 26, the spring ball 28 will produce resistance to the hemispherical groove 26, and then when the spring ball 28 and the hemispherical groove 26 continue to engage, the trapezoidal slider 24 will vibrate again, and at the same time, it will drive the nutrient solution pool 12 and the connecting plate 21 connected thereto and other components to vibrate together, making the vibration effect more obvious. During the two vibrations of the connecting plate 21 and the inside of the cultured seedlings, the impurities in the cultured seedlings gradually fall into the inside of the nutrient solution pool 12.

[0065] After the staff places multiple groups of connecting plates 21 and cultured seedlings in the nutrient solution pool 12 in turn, they press the connecting plates 21 and the nutrient solution pool 12. The same as the above-mentioned movement process will cause the nutrient solution pool 12 and the connecting plates 21 and cultured seedlings connected thereto to vibrate, so that the impurities in the cultured seedlings gradually fall into the nutrient solution pool 12.

[0066] Then the staff starts the water pump 13. During the process of starting the water pump 13, water is first injected into the nutrient solution pool 12 through two water pipes, and then the water source and impurities in the nutrient solution pool 12 are removed through the outlet pipe. Finally, the nutrient solution is injected into the nutrient solution pool 12 through the water inlet pipe. At the same time, the nutrient solution injected into the nutrient solution pool 12 is circulated through the two water inlet pipes and the water outlet pipe of the water pump 13, so that the culture seedlings that slide down a certain distance toward the bottom of the connecting plate 21 can better contact with the nutrient solution.

[0067] When the seedlings absorb nutrients from the nutrient solution, the cross-limiting plate 43 and the telescopic block 44 above the connecting plate 21 will restrict the growth of the seedlings to prevent the seedlings from being entangled with each other during the growth process. At the same time, the blocking of the cross-limiting plate 43 and the telescopic block 44 will prevent the seedlings from growing crookedly to a certain extent, and play a certain straightening effect.

[0068] Secondly, as the culture seedlings grow, when the height of the culture seedlings is about to exceed the horizontal height of the cross limit plate 43 and the telescopic block 44, the staff can slide the telescopic blocks 44 on the upper and lower sides of the cross limit plate 43 so that the cross limit plate 43 and the telescopic block 44 can still protect the grown culture seedlings;

[0069] When cultivating seedlings at a higher height, if pulling the telescopic blocks 44 on the upper and lower sides of the cross limit plate 43 to slide still cannot meet the growth needs of the seedlings, the staff can start the servo motor 45 to make the servo motor 45 drive the threaded rod 46 on the output shaft to rotate. During the rotation of the threaded rod 46, the double-layer slide plate 42 that is threadedly matched with it will rise, so that the double-layer slide plate 42 drives the cross limit plate 43 and the telescopic block 44 to rise synchronously along the inside of the vertical groove 41, thereby achieving the adjustment of the height of the cross limit plate 43 and the telescopic block 44, so that the cross limit plate 43 and the telescopic block 44 can always cooperate with the growth of the seedlings.
