Description

Technical Field

[0002] At present, the spectacular scene of seedling raising in the circulating motion seedling raising bed and its intelligent control interface highlight the high-end of modern agricultural machinery, but its pre-process still remains in the traditional agronomic process mode. It requires concentrated use of manpower during seed soaking and disinfection, sowing and germination, and transportation. In order to save manpower and reduce costs, many projects are equipped with electric hoists to lift seed bags from the beginning of seed soaking. The simple sowing section uses seedling tray feeding machine, matrix seed loader, sowing machine, tray stacking machine, roller (or belt) conveyor line, stacking robot and other equipment, and then the pallets are transported by forklift to the germination chamber for constant temperature and humidity germination. After 48 hours, a forklift is used to transport them from the chamber to the seedling bed for seedling raising; in order to reflect the mechanization and automation of the process, some projects have added robots to transfer the seedling tray to the belt conveyor to the front end of the seedling bed, and also added robots to clamp the seedling tray to the seedling bed hanging basket.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0076] See also Figures 1 to 9 This embodiment provides a complete set of intelligent seedling raising equipment, including a constant temperature and oxygenated seed soaking device 1, a circulating seedling raising bed 2, a track soil spreading seeder 3, a humidifying device 4, a telescopic greenhouse 5 and an intelligent adjustment device 6.

[0077] The constant temperature oxygenated seed soaking device 1 comprises a water tank 11, a constant temperature component 12, an aeration component 13 and an inlet and outlet assembly 14. The constant temperature component 12, the aeration component 13 and the inlet and outlet assembly 14 are connected to the water tank 11.

[0078] The circulating seedling raising bed 2 comprises a seedling raising bed frame 21, a circulating component 22, and a seedling raising tray 23 arranged on the circulating component 22. The circulating component 22 is movably connected to the seedling raising bed frame 21 to drive the seedling raising tray 23 to move along a first motion trajectory.

[0079] The track soil spreading seeder 3 is connected to the seedling bed frame 21 and is located at one end of the first motion track. The track soil spreading seeder 3 is used to spread substrate or seeds into the seedling raising tray 23 .

[0080] The humidifying device 4 is connected to the seedling bed frame 21 and is located at the other end of the first motion track, and is used to apply water and fertilizer to the seedling raising tray 23.

[0081] The telescopic greenhouse 5 includes a greenhouse support frame 51, a telescopic top frame 52 and a first insulation film 53 that can be stored or laid on the side of the greenhouse support frame 51. The telescopic top frame 52 is movably connected to the top of the greenhouse support frame 51, and a second insulation film 54 is provided on the telescopic top frame 52.

[0082] The intelligent regulating device 6 is connected to the constant temperature oxygenated seed soaking device 1 , the circulating seedling raising bed 2 , the humidifying device 4 and the telescopic greenhouse 5 .

[0083] Among them, the soaking process is the water absorption process of the seeds. After the seeds absorb water, the activity of the seed enzyme begins to rise. Under the action of the enzyme activity, the endosperm starch gradually dissolves into sugar, releasing the nutrients needed for the radicle, plumule and hypocotyl. When the seeds absorb enough water, the seeds can germinate normally, and the time to reach sufficient water absorption is affected by the soaking water temperature. Within a certain temperature range, the higher the temperature, the faster the seeds absorb water, and the shorter the time to reach saturated water absorption. Therefore, the soaking process of seeds is relatively cumbersome, and an intermittent soaking method is usually adopted, which requires continuous repetition of the soaking and fishing process, and stops soaking after two to three days. The constant temperature oxygenated seed soaking device 1 provided in this embodiment, after the seeds are placed in the water tank 11, the water inlet and outlet assembly 14 can inject water into the water tank 11 to submerge the seeds, and the aeration assembly 13 can inject air into the water to enrich the water with oxygen, and the constant temperature assembly 12 can also control the water temperature to keep the water in the water tank 11 within a certain temperature range for germination. After the seeds are soaked for a period of time, the aeration component 13 and the constant temperature component 12 can stop working, and the water inlet and outlet component 14 discharges the water in the water tank 11 to drain the seeds in the water tank 11. After a period of time, the water inlet and outlet component 14 continues to inject water to achieve intermittent soaking of the seeds.

[0084] The circulating seedling bed 2 is a circulating motion seedling bed. The first motion trajectory can be a motion trajectory along the periphery of the seedling bed frame 21, or a motion trajectory of a linear reciprocating motion. In the embodiment provided in this embodiment, the first motion trajectory is divided into two parts, such as Figure 3 As shown, the lower part is a linear motion track from the tail to the head of the seedling bed frame 21, and the upper part is a curved motion track from the head to the tail of the seedling bed frame 21 while continuously and repeatedly moving up and down. The track soil spreading seeder 3 is located above one end of the head of the linear motion track, and when the seedling tray 23 moves, the soil matrix and seeds are spread into the seedling tray 23; the humidifying device 4 is located above one end of the tail of the linear motion track, and when the seedling tray 23 moves, water vapor and fertilizer can be sprayed into the seedling tray 23. After the seedling tray 23 passes through the linear motion track, the excess water that has not been absorbed is drained out, and then it moves upward through the curved motion track, which prevents water from dripping from the upper plate to the lower plate, thereby causing the matrix and seeds in the seedling tray 23 to be splashed into holes by dripping water, making the matrix surface uneven and the seeds exposed, affecting the germination and growth of the seeds.

[0085] Among them, the seedling tray 23 can be a bottomless hanging basket, and the staff can spread the seeds and the matrix in the seedling tray, and then place the seedling tray in the bottomless hanging basket. The seedling tray 23 can also be a bottomed hanging basket, and a number of water-leaking air holes are opened at the bottom of the hanging basket. A hanging basket has the function of a large seedling tray, and can also be equivalent to a number of seedling trays. The rice seedling blanket cultivated in this way can be rolled up as a whole and directly used for transplanting in the field by a rice transplanter, or it can be cut and rolled into small rolls of several lengths according to one's own preferences and the model of the rice transplanter. The seedling tray 23 can be a water-proof structure, and a plurality of grooves can be arranged in parallel at the bottom of the seedling tray 23, and the bottom is inclined along the length direction of the groove, so that the moisture in the seedling tray 23 can be concentrated in the groove and then discharged uniformly.

[0086] See also Figure 7 The top of the telescopic greenhouse 5 can be opened and closed movably, and the second thermal insulation film 54 is arranged on the top of the telescopic top frame 52. When the telescopic top frame 52 contracts, the second thermal insulation film 54 is stored, and the top of the greenhouse is ventilated and lit. When the telescopic top frame 52 is unfolded, the second thermal insulation film 54 is unfolded synchronously to make the top of the greenhouse sealed. The first thermal insulation film 53 on the side of the telescopic greenhouse 5 can also be stored or unfolded to make the greenhouse ventilated or sealed as a whole.

[0087] The intelligent adjustment device 6 is connected to the constant temperature oxygenated seed soaking device 1, the circulating seedling raising bed 2, the humidifying device 4 and the telescopic greenhouse 5, and can be used to obtain the water temperature and oxygen content in the water tank 11, the substrate humidity in the seedling raising tray 23, the fertilizer concentration applied by the humidifying device 4 and the light intensity in the telescopic greenhouse 5, etc., and can also obtain the growth status of seeds or seedlings through cameras, etc. After big data collection, the temperature, humidity, oxygen content, fertilizer concentration and light intensity required for the optimal growth state are determined by program or manual, and the constant temperature component 12, the aeration component 13, the humidifying device 4 and the telescopic greenhouse 5 are controlled to adjust various parameters, so as to optimize the growth environment of seeds or seedlings. The intelligent adjustment device 6 can also include an intelligently adjustable spectrum LED light source to adapt to the different light sources required by different crops at different seedling stages.

[0088] The intelligent rice seedling raising equipment set provided by this embodiment reduces equipment facilities and process logistics, and optimizes the structural function of the circulating mobile rice seedling raising bed. The ordinary seed soaking method is changed to a constant temperature and humidity oxygenation method, and the water is automatically changed and free water is removed during the process; the expensive sowing production line, robot, forklift, stacking tray and germination chamber are eliminated; a circulating rice seedling raising bed is directly adopted, and the track soil spreading seeder and the seedling bed are synchronized for sowing; the rice seedling raising tray can directly receive the soil and seed spreading of the seeder; humidification and fertilization are carried out at the tail of the seedling bed frame, and oxygenation spray humidification or watering humidification can be used at different seedling stages; the seedling bed adopts a telescopic greenhouse, which can be retracted and covered to darken and heat and moisturize, has the function of germination and adapting to the cultivation of shade-loving crops, and can shorten the cultivation cycle; the intelligent adjustment device can establish a database during the rice seedling cultivation process, and conduct digital logic control on the temperature, humidity, phosgene and fertilizer modeling required during the crop growth period through the acquired data and the data of the continued test. The above functions are integrated to achieve the purpose of improving the quality of rice seedlings, saving energy and labor, and intelligently saving costs.

[0089] Furthermore, the track soil-laying seeder 3 includes a track 31 , a soil-laying mechanism 32 , a sowing mechanism 33 and a soil-covering mechanism 34 .

[0090] There are multiple rails 31 , and the multiple rails 31 are arranged in parallel on the seedling bed frame 21 .

[0091] The soil spreading mechanism 32 is slidably arranged on the track 31, and comprises a first buffer hopper 321 and a first material spreading assembly 322. The first material spreading assembly 322 is connected to the bottom of the first buffer hopper 321, and the first buffer hopper is used for placing the substrate.

[0092] The sowing mechanism 33 is slidably set on the track 31 and is located behind the soil spreading mechanism 32 along the movement direction of the seedling tray 23. It includes a second cache hopper 331 and a second spreading assembly 332. The second spreading assembly 332 is connected to the bottom of the second cache hopper 331. The second cache hopper 331 is used to place seeds.

[0093] The soil covering mechanism 34 is slidably arranged on the track 31 and is located behind the sowing mechanism 33 along the movement direction of the seedling tray 23. It includes a third cache hopper 341 and a third spreading assembly 342. The third spreading assembly 342 is connected to the bottom of the third cache hopper 342. The third cache hopper 341 is used to place the substrate.

[0094] The track 31 can be arranged perpendicular to the linear motion track and parallel to the length direction of the seedling tray 23. When the seedling tray 23 moves to the bottom of the track soil spreading seeder 3, the mechanism at this position can slide along the track 31 and spread the substrate or seeds at the same time, so as to spread the substrate or seeds evenly along the length direction of the seedling tray 23. Figure 3The soil spreading mechanism 32, the sowing mechanism 33 and the soil covering mechanism 34 are arranged front and back along the moving direction of the seedling raising tray 23. When the seedling raising tray 23 moves, the soil spreading mechanism 32 first spreads the soil matrix into the seedling raising tray 23, and then the sowing mechanism 33 sprinkles the seeds, and finally the soil covering mechanism 34 continues to spread the soil matrix to cover the lower matrix and the seeds together.

[0095] For further information, see Figure 2 , in the implementation manner provided in this implementation manner:

[0096] The thermostatic assembly 12 includes a water outlet pipe 121 , a water return pipe 122 and a heating module 123 . One end of the water outlet pipe 121 and the water return pipe 122 are connected to the water tank 11 , and the other end is connected to the heating module 123 .

[0097] The aeration assembly 13 includes an aeration plate 131 and an isolation grid plate 132 . The isolation grid plate 132 is disposed in the water tank 11 to divide the inner space thereof into a seed soaking chamber 111 and an aeration chamber 112 . The aeration plate 131 is located in the aeration chamber 112 .

[0098] The water inlet and outlet assembly 14 includes a water inlet pipe 141 , a water outlet pipe 142 and a liquid level controller 143 . The water inlet pipe 141 is connected to the seed soaking chamber 111 , the water outlet pipe 142 is connected to the aeration chamber 112 , and the liquid level controller 143 is arranged on the inner wall of the water tank 11 .

[0099] Among them, the water outlet pipe 121 can transport the water in the water tank 11 to the heating module 123. The heating module 123 heats the water and then transports it back to the water tank 11 through the return pipe 122. Since the water temperature in the upper layer of the water body is relatively low, the water outlet pipe 121 can be connected to the upper part of the water tank 11, and the return pipe 122 is connected to the lower part of the water tank 11, so that the temperature of each part of the water body in the water tank 11 is uniform.

[0100] The isolation grid plate 132 has a plurality of holes. The isolation grid plate 132 can be horizontally arranged in the water tank 11 to divide the water tank 11 into an upper seed soaking chamber 111 and a lower aeration chamber 112. The isolation grid plate 132 connects the water in the seed soaking chamber 111 and the water in the aeration chamber 112. However, since the holes in the isolation grid plate 132 are too small, the seeds are separated by the isolation grid plate 132. Therefore, when the water inlet and outlet assembly 14 drains the water in the water tank 11, the seeds will stay on the isolation grid plate 132, thereby draining the seeds. The number of aeration discs 131 can be multiple, and multiple aeration discs 131 can be evenly dispersed at the bottom of the water tank 11, that is, in the aeration chamber 112. The aeration discs 131 can be connected to a compressed air machine through a pipeline, so that compressed air is injected into the water to increase the oxygen content in the water.

[0101] The water inlet pipe 141 can be connected to the upper layer of the water tank 11, and the drain pipe 142 can be connected to the lower layer of the water tank 11, so as to drain the water in the water tank 11. The liquid level controller 143 can be set at the required liquid level height. When the water in the water tank 11 reaches the required liquid level, the water inlet pipe 141 can be controlled to stop filling water.

[0102] Furthermore, the circulation component 22 includes a driving member 221 , a transmission wheel 222 and a transmission belt 223 .

[0103] The driving member 221 is disposed on the seedling bed frame 21 .

[0126] This embodiment further provides a seedling raising process, which uses the intelligent seedling raising equipment set as described in any one of the above, and the seedling raising process includes the following steps:

[0127] Step 1: Put the seeds into the water tank 11. The water inlet and outlet assembly 14, the aeration assembly 13 and the constant temperature assembly 12 force the seeds in the water tank 11 to repeatedly switch between the soaking state and the draining state, and stop after a first time interval. The intelligent adjustment device 6 obtains the temperature of the water in the water tank 11, the oxygen content in the water, and the first growth state of the seeds.

[0128] Step 2: Put the seeds into the track soil spreading seeder 3, the track soil spreading seeder 3 spreads the seeds and the matrix in the seedling raising tray 23, and the circulation component 22 drives the seedling raising tray 23 to move along the first motion trajectory.

[0129] Step 3: The humidifying device 4 applies water and fertilizer into the seedling raising tray 23, and the intelligent regulating device 6 obtains the humidity in the seedling raising tray 23, the concentration of the applied fertilizer, and the second growth state of the seedlings.

[0130] Step 4: The seedlings are moved into the telescopic greenhouse 5 for cultivation, and the intelligent regulating device 6 obtains the light intensity in the telescopic greenhouse 5 and the third growth state of the seedlings.

[0131] Step 5: The intelligent regulating device 6 records the temperature, oxygen content, the first growth state, humidity, fertilizer concentration, the second growth state, light intensity and the third growth state, and controls the constant temperature component 12, the aeration component 13, the humidifying device 4 and the telescopic greenhouse 5 after digital modeling.

[0132] Among them, in step 1, the first time interval can be two to three days, or it can be the time of intelligent control after the intelligent adjustment device 6 obtains various parameters and models them. The water tank 11 can realize automatic water change and free water removal, so that the seeds can be automatically soaked and drained therein; in step 2, the matrix used by the track soil-laying seeder 3 can be a matrix or other materials. The track soil-laying seeder 3 can lay the matrix on the bottom of the seedling tray 23, and then lay the seeds and the covering soil layer on top in turn, and the covering soil layer covers the bottom matrix and seeds together; in step 3, the intelligent adjustment device 6 can obtain the concentration of the applied fertilizer by connecting the spraying structure of the humidification device 4; in step 5, the intelligent adjustment device 6 records the various parameters obtained and performs digital modeling, so as to obtain the conditions required for the seeds or seedlings to reach the optimal growth state, which can control the growth conditions of the seeds or seedlings to achieve the optimal growth state, and can also be used for cultivation experiments.

[0135] The draining state includes the water inlet and outlet assembly 14 draining the water in the water tank 11, and the aeration assembly 13 and the constant temperature assembly 12 stopping working.

[0136] Among them, when the seeds are in a soaking state, the constant temperature component 12 and the aeration component 13 can make the temperature and oxygen content in the water reach the optimal value, which is convenient for the seeds to absorb water; when the seeds are in a draining state, the seeds can fully contact with oxygen, thereby achieving intermittent soaking of the seeds.

[0137] Furthermore, the track soil spreading seeder 3 spreads the seeds and the matrix in the seedling raising tray 23, specifically including the following steps:

[0138] Step 1: The circulation component 22 drives the seedling raising tray 23 to move to the first position, and the soil spreading mechanism 32 spreads the matrix in the seedling raising tray 23 to form a matrix layer.

[0139] Step 2: The circulation component 22 drives the seedling raising tray 23 to move to the second position, and the sowing mechanism 33 spreads the seeds on the substrate layer.

[0140] Step 3: The circulation component 22 drives the seedling raising tray 23 to move to the third position, and the soil covering mechanism 34 spreads the substrate on the substrate layer and covers the seeds.

[0141] The first position is below the soil spreading mechanism 32, the second position is below the sowing mechanism 33, and the third position is below the soil covering mechanism 34. Driven by the circulation component 22, the seedling tray 23 can be moved to the bottom of the soil spreading mechanism 32, the sowing mechanism 33 and the soil covering mechanism 34 in sequence, and the soil spreading mechanism 32, the sowing mechanism 33 and the soil covering mechanism 34 perform soil spreading, sowing and soil covering respectively.

[0144] See also Fig. 9 In the seed soaking and germination stage, the temperature sensor 61, the oxygen content sensor 65 and the seedling status monitor 66 obtain the water temperature, the oxygen content in the water and the growth status of the seeds in the water tank 11;

[0145] During the sowing, humidification and fertilization stage, the humidity sensor 62 obtains the substrate humidity in the seedling tray 23, the fertilizer amount detection sensor 64 obtains the concentration of the applied fertilizer, and the seedling status monitor 66 obtains the growth status of the seedlings in the seedling tray;

[0146] During the cultivation stage in the telescopic greenhouse 5 , the light intensity sensor 63 obtains the light intensity in the telescopic greenhouse 5 , and the seedling status monitor 66 obtains the growth status of the seedlings in the telescopic greenhouse 5 .

[0147] The processor records the water temperature, oxygen content in the water, substrate humidity, fertilizer concentration, light intensity, and growth status of seeds and seedlings, and performs digital modeling to determine the various parameters required for the seeds and seedlings to achieve optimal growth status, and then controls the constant temperature component 12, aeration component 13, humidification device 4 and telescopic greenhouse 5 to achieve the optimal growth environment for seeds and seedlings.
