Intelligent agriculture features high technical specifications and highly efficient intensive scale management, and is widely applied in large and medium-sized agricultural planting bases, facility horticulture, livestock and aquatic breeding, etc. Among them, intelligent seeding and fertilizing devices are important equipment in modern agricultural production.

[0003] Currently, when the existing seeding device sows seeds, it is necessary to apply liquid fertilizer to the sown seeds immediately and let the liquid fertilizer stand on the seeding device. However, some components in the liquid fertilizer may precipitate or crystallize after standing for a long time, resulting in uneven fertilization or clogging of the pipeline, thus weakening the fertilization effect. Especially when sowing seeds in cold regions, when applying liquid fertilizer, the low-temperature liquid fertilizer is applied to the soil, which may freeze the seeds and reduce the germination rate of the seeds. Moreover, soil microorganisms are not active enough under low-temperature conditions, so the reproduction and decomposition of microorganisms are restricted. In view of this, we propose a seeding device for agricultural planting. Summary of the Invention

[0010] As a further improvement of this technical solution, the fertilizing mechanism includes a water pump. The bottom of the water pump is fixedly arranged on the other side of the top of the frame. The input end of the water pump is fixedly communicated with a first water delivery pipe, and the end of the first water delivery pipe away from the water pump is fixedly communicated with the liquid fertilizer barrel.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1.

Moreover, the heating mechanism heats the liquid fertilizer in cooperation with the stirring mechanism, the temperature of the liquid fertilizer rises, making the liquid fertilizer molecules and water molecules diffuse faster, improving the fluidity of the liquid fertilizer, promoting the dissolution of precipitation and crystallization, and enhancing the uniformity of the liquid fertilizer, which is beneficial to further enhancing the fertilizing effect.

Specific embodiments

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Intelligent seeding and fertilizing devices are important equipment for modern agricultural production. Through intelligent agriculture, a new type of agricultural production method that deeply integrates modern information technology, intelligent equipment, etc. with agriculture, realizes information perception, quantitative decision-making, intelligent control and precise input throughout the entire process of agricultural production through technologies such as the Internet of Things, big data, and artificial intelligence. Intelligent agriculture has the characteristics of high technical specifications and highly efficient intensive scale management. For this reason, the present invention provides a seeding device for agricultural planting. Please refer to Figures 1-8, which includes a rotary tillage part 1 for turning the soil. The rotary tillage part 1 includes structures such as a frame, an engine, a transmission shaft, and rotary cutters. The engine drives the rotary cutters to operate. During the rotation of the rotary cutters, frictional force is generated with the soil, turning the soil under the rotary cutters to form furrows and ridges. After the soil is turned up, through the action of the rotary cutters, the soil is mixed with the surrounding air, improving the air permeability and looseness of the soil, thus achieving the purpose of rotary tillage and soil turning. On one side of the rotary tillage part 1, a seeding part 2 for seeding is installed. The seeding part 2 mainly includes structures such as a fertilizer and seed box, a seed conveying roller, and a drive machine. The drive machine drives the seed conveying roller to rotate, continuously outputting the seeds in the fertilizer and seed box into the soil to complete the seeding operation. On one side of the seeding part 2, a frame 3 is fixedly arranged. On one side of the top of the frame 3, a liquid fertilizer barrel 4 for containing and mixing liquid fertilizer is fixedly arranged. In the center of the interior of the liquid fertilizer barrel 4, a stirring mechanism 5 for stirring the liquid fertilizer is arranged. On the inner side wall of the liquid fertilizer barrel 4, a plurality of heating mechanisms 6 for heating the liquid fertilizer are arranged. On the other side of the top of the frame 3, a fertilizing mechanism 7 for sending the liquid fertilizer out of the liquid fertilizer barrel 4 and applying fertilizer is arranged. At the bottom of the frame 3, a lifting mechanism 8 is arranged for driving the output end of the fertilizing mechanism 7 and the seeding part 2. The output end of the seeding part 2, that is, the port where the seeding part 2 outputs seeds, moves vertically to adapt to different soil surface depths. Among them:

[0031] As shown in the present invention Figures 1-3 When considering that when the seeding part 2 finishes seeding and immediately applies liquid fertilizer to the sown seeds, the liquid fertilizer is static in the liquid fertilizer barrel 4, and some components in the liquid fertilizer may precipitate or crystallize after long-term standing, resulting in uneven fertilization or blocking of the fertilizing mechanism 7, thus weakening the fertilization effect. Therefore, as Figures 4-5 shown, by the self-rotation of the stirring mechanism 5, the liquid fertilizer in the liquid fertilizer barrel 4 is continuously stirred, preventing the liquid fertilizer from precipitating and crystallizing, making the water and fertilizer more uniform, and also avoiding the blockage of the fertilizing mechanism 7, which is beneficial to enhancing the fertilization effect. And the heating mechanism 6 heats the liquid fertilizer in cooperation with the stirring mechanism 5, the temperature of the liquid fertilizer rises, making the liquid fertilizer molecules and water molecules diffuse faster, improving the fluidity of the liquid fertilizer, promoting the dissolution of precipitation and crystallization, and enhancing the uniformity of the liquid fertilizer, which is beneficial to further enhancing the fertilization effect;

[0032] And considering that since the positional relationship between the output end of the fertilizing mechanism 7 and the soil generally remains unchanged, when the sown seeds are located deep in the soil surface layer, when the liquid fertilizer is applied to the soil, the liquid fertilizer may not penetrate deep into the soil, so that the seeds cannot well absorb the fertility of the liquid fertilizer, further weakening the fertilization effect. Therefore, as Figure 2 and Figure 4As shown, by the self - movement of the lifting mechanism 8 and the cooperation of the fertilizing mechanism 7 to adjust the output end of the fertilizing mechanism 7, the positional relationship between the output end of the fertilizing mechanism 7 and the soil is adjusted, so that the liquid fertilizer after being fully stirred by the stirring mechanism 5 can more easily penetrate into the soil position where the seeds are located according to the fertilization requirements, which is beneficial to further enhancing the fertilization effect of the liquid fertilizer;

[0033] Moreover, when the sowing part 2 sows seeds in cold regions and applies liquid fertilizer, the low - temperature liquid fertilizer is applied to the soil, which may freeze the seeds and reduce the germination rate of the seeds. And the microorganisms in the soil are not active enough under low - temperature conditions, so that the reproduction and decomposition of microorganisms are restricted. Therefore, as Figure 3 and Figure 5 shown, the heating mechanism 6 senses the temperature of the liquid fertilizer by itself, compares it with the ambient temperature, and then generates heat to heat the liquid fertilizer in the liquid fertilizer tank 4 until the liquid fertilizer reaches the temperature required for the normal growth of seeds during sowing and the normal reproduction and decomposition of microorganisms in the soil, preventing the low - temperature liquid fertilizer from being applied to the soil and freezing the seeds, improving the germination rate of the seeds, enhancing the activity of microorganisms in the soil, and the stirring mechanism 5 rotates in cooperation with the heating mechanism 6. The stirring mechanism 5 stirs the liquid fertilizer, so that the high - temperature liquid fertilizer near the heating mechanism 6 flows to other positions in the liquid fertilizer tank 4, enabling the liquid fertilizer in the liquid fertilizer tank 4 to be heated faster and more evenly, promoting the liquid fertilizer to reach the required temperature as soon as possible and improving the heating efficiency.

[0034] On the above basis, the specific structure is disclosed in detail:

[0035] To realize the self - rotation of the stirring mechanism 5 to stir the liquid fertilizer in the liquid fertilizer tank 4 to prevent the liquid fertilizer from precipitating and crystallizing, the specific structure of the stirring mechanism 5 needs to be disclosed. Therefore, as Figure 5 shown, the stirring mechanism 5 includes a plurality of stirring shafts 51. The plurality of stirring shafts 51 are all rotatably arranged in the liquid fertilizer tank 4. A plurality of groups of stirring blades 52 for stirring the liquid fertilizer are fixedly arranged on the surfaces of the plurality of stirring shafts 51. By the rotation of the stirring shafts 51 and the stirring blades 52, the liquid fertilizer contained inside the liquid fertilizer tank 4 is stirred, and the liquid fertilizer continuously flows, collides and mixes in the liquid fertilizer tank 4, so that the liquid fertilizer is in a moving state for a long time, preventing the liquid fertilizer from precipitating and crystallizing and improving the uniformity of the liquid fertilizer.

[0036] Among them, a driving force is required to drive the rotation of the stirring shafts 51 and the stirring blades 52 to achieve the purpose of stirring and mixing the liquid fertilizer in the liquid fertilizer tank 4. Then, the specific structure of the stirring mechanism 5 needs to be further disclosed. Therefore, as Figure 4As shown in the figure, the stirring mechanism 5 further includes a motor 53. The motor 53 is fixedly installed at the center of the top of the liquid fertilizer tank 4. The output end of the motor 53 passes through the liquid fertilizer tank 4 and is fixedly connected to the top end of the stirring shaft 51 located at the center of the liquid fertilizer tank 4. A plurality of gears 54 are fixedly arranged on the outer walls of the stirring shafts 51, and adjacent gears 54 are meshed with each other. The motor 53 rotates by itself to generate a driving force, driving the connected stirring shaft 51 to rotate self - clockwise, and then driving the gear 54 fixed on the stirring shaft 51 to rotate around the axis of the stirring shaft 51 (as Figure 6 shown), and then driving the other connected gears 54 to rotate around the axes of their respective corresponding stirring shafts 51, and then driving a plurality of stirring blades 52 to rotate, fully stirring and mixing the liquid fertilizer in the liquid fertilizer tank 4, preventing the liquid fertilizer from precipitating and crystallizing, and improving the uniformity of the liquid fertilizer.

[0037] Considering that the heating mechanism 6 needs to heat the liquid fertilizer in the liquid fertilizer tank 4 according to the fertilization requirements, so that the temperature of the liquid fertilizer meets the requirements of seeds and production, to avoid freezing the seeds, and to ensure the normal reproduction and decomposition of microorganisms, it is necessary to disclose the specific structure of the heating mechanism 6. Therefore, as Figure 5 shown, a plurality of heating mechanisms 6 each include a mounting ring 61. The outer walls of the plurality of mounting rings 61 are fixedly arranged on the inner side walls of the liquid fertilizer tank 4. A group of heating tubes 62 for heating the liquid fertilizer are fixedly arranged in the inner circles of the plurality of mounting rings 61, and the plurality of groups of heating tubes 62 are all located between adjacent two groups of stirring blades 52. The heating tubes 62 start by themselves to generate heat and heat the liquid fertilizer in the liquid fertilizer tank 4. The heating tubes 62 heat the liquid fertilizer in the liquid fertilizer tank 4, raising the temperature of the liquid fertilizer to the temperature required for seed growth, preventing the water and fertilizer from freezing the seeds, ensuring the normal reproduction and decomposition of microorganisms in the soil, and improving the seed germination rate. And start the motor 53 to drive the stirring shaft 51 and the stirring blades 52 to rotate, stirring the liquid fertilizer, so that the heated liquid fertilizer with a higher temperature near the heating tubes 62 flows to other positions in the liquid fertilizer tank 4, making the liquid fertilizer constantly stirred. The heating tubes 62 can heat the liquid fertilizer in the liquid fertilizer tank 4 faster and more evenly, improving the heating efficiency. Moreover, when the heating tubes 62 heat the liquid fertilizer, as the temperature of the liquid fertilizer rises, the precipitation and crystallization in the liquid fertilizer are accelerated to dissolve in the liquid fertilizer, which can also improve the uniformity of the liquid fertilizer and is beneficial to further enhancing the fertilization effect.

[0038] Among them, the heating mechanism 6 needs to sense the temperature of the liquid fertilizer and the external temperature by itself, and heat the liquid fertilizer according to the temperature required for the normal growth of the seeds. So the heating mechanism 6 further includes a liquid fertilizer temperature sensing module, an ambient temperature sensing module and a control panel:

[0039] The liquid fertilizer temperature sensing module is used to sense the temperature data of the liquid fertilizer inside the liquid fertilizer tank 4. The liquid fertilizer temperature sensing module includes structures such as an internal temperature sensor, and the internal temperature sensor senses the temperature data of the liquid fertilizer inside the liquid fertilizer tank 4;

[0040] The ambient temperature sensing module is used to sense the ambient temperature data outside the liquid fertilizer bucket 4. The ambient temperature sensing module includes structures such as an external temperature sensor. The external temperature sensor senses the ambient temperature data outside the liquid fertilizer bucket 4;

[0041] The control panel is used to provide a switch button for the heating tube 62, and judge the liquid fertilizer temperature data sensed by the liquid fertilizer temperature sensing module and the ambient temperature data sensed by the ambient sensing module, so as to automatically control the heating tube 62 to start and heat the liquid fertilizer in the liquid fertilizer bucket 4. The control panel includes structures such as a processor. The processor is used to judge the liquid fertilizer temperature data and the ambient temperature data to decide whether to start the heater 62.

[0042] Considering that it is necessary to pump the liquid fertilizer out of the liquid fertilizer bucket 4 and pour it onto the soil where sowing has been completed to complete the fertilization operation, it is necessary to disclose the specific structure of the fertilization mechanism 7. Therefore, as Figure 4 shown, the fertilization mechanism 7 includes a water pump 71. The water pump 71 includes structures such as an electric motor, a pump casing and an impeller. The impeller is driven to rotate by the electric motor. When the impeller rotates, the liquid between the blades also rotates. Under the action of centrifugal force, the liquid is thrown out of the impeller and enters the pump casing. As the liquid is continuously thrown out, a low-pressure area is formed at the center of the impeller. The external liquid is sucked into the center of the impeller under the action of atmospheric pressure to fill the low-pressure area. As long as the impeller keeps rotating, the water pump 71 will continuously suck in and discharge the liquid, thereby realizing the continuous transportation of the liquid. The bottom of the water pump 71 is fixedly arranged on the other side of the top of the frame 3. The input end of the water pump 71 is fixedly connected with a first water delivery pipe 72. The end of the first water delivery pipe 72 away from the water pump 71 is fixedly connected to the liquid fertilizer bucket 4. By the operation of the water pump 71, the liquid fertilizer in the liquid fertilizer bucket 4 continuously enters the water pump 71 through the first water delivery pipe 72, and the liquid fertilizer is pumped out of the liquid fertilizer bucket 4 for subsequent pouring of the liquid fertilizer on the soil to complete the fertilization operation.

[0043] Among them, when the liquid fertilizer flows from the liquid fertilizer bucket 4 into the water pump 71 and continues to fertilize, it is often necessary to count the total amount of liquid fertilizer used for fertilization to avoid over-fertilization and further improve the fertilization efficiency. It is necessary to continue to disclose the specific structure of the fertilization mechanism 7. As Figure 4 shown, the output end of the water pump 71 is fixedly connected with a flow meter 73 for recording the liquid fertilizer flow rate. By the operation of the flow meter 73, the total amount of liquid fertilizer flowing through the water pump 71 and the flow meter 73 is recorded to prevent over-fertilization, which is beneficial to further improving the fertilization efficiency.

[0044] Among them, the liquid fertilizer flows through the first water delivery pipe 72, the water pump 71 and the flow meter 73, and needs to continue to flow inside the fertilization mechanism 7 and finally be poured on the soil. It is necessary to continue to disclose the specific structure of the fertilization mechanism 7. Therefore, as Figure 4As shown in the figure, the output end of the flowmeter 73 is fixedly connected to a pipe network 74. The pipe network 74 is fixedly arranged on the frame 3. Multiple output ends of the pipe network 74 are all fixedly connected to flexible hoses 75. One end of each of the multiple flexible hoses 75 away from the pipe network 74 is fixedly connected to a second water delivery pipe. One end of the second water delivery pipe away from the flexible hose 75 is fixedly connected to a U-shaped water guide pipe 76. Both ends of the U-shaped water guide pipe 76 are fixedly connected to nozzles 77 for discharging liquid fertilizer. The nozzle 77 includes a nozzle, an opening and closing mechanism (including a gear ring, a transmission shaft, a closing plate, etc.), a sliding rod, a floating ball and other structures. When water flows through the nozzle 77, the floating ball rises with the water flow, drives the gear ring and the transmission shaft to rotate through the sliding rod, and then controls the closing plate to open the nozzle. After the irrigation or spraying is over, the water flow stops, the floating ball descends, and the closing plate closes the nozzle under the action of a spring or gravity to prevent external soil and impurities from entering. And the output end of the sowing part 2 is arranged between the two nozzles 77. The liquid fertilizer flowing out of the flowmeter 73 flows through the pipe network 74, flows out from each output end of the pipe network 74 into the flexible hoses 75, is then divided into two streams through the second water delivery pipe, and the two streams of liquid fertilizer continue to flow along the inner parts of both ends of the U-shaped water guide pipe 76, and finally flow out from the nozzles 77 into the soil to complete the fertilization operation.

[0045] To be able to flexibly change the positional relationship between the nozzle 77 and the soil, it is necessary to disclose the specific structure of the lifting mechanism 8. Therefore, as Figure 4 shown, the lifting mechanism 8 includes a mounting plate 81 and multiple cylinders 82. The tails of the multiple cylinders 82 are all fixedly arranged at the bottom of the frame 3. The output ends of the multiple cylinders 82 are fixedly fitted with one side of the top of the mounting plate 81. Multiple through holes are provided on the other side of the top of the mounting plate 81. The second water delivery pipe is fixedly arranged in the through holes. By the elongation and shortening of the cylinders 82 themselves, the mounting plate 81 is driven to move along the vertical direction, and then the second water delivery pipe, the U-shaped water guide pipe 76 and the nozzle 77 are driven to move along the vertical direction (as Figure 7 shown), thereby changing the positional relationship between the nozzle 77 and the soil, so that the nozzle 77 can penetrate into various positions on the soil surface, and the liquid fertilizer after being fully stirred by the stirring shaft 51 and the stirring blades 52 can more easily penetrate into the soil position where the seeds are located according to the fertilization requirements, which is beneficial to further enhancing the fertilization effect of the liquid fertilizer.

[0046] Since the cylinders 82 move along the vertical direction to drive the nozzle 77 to move to adapt to different positions of the seeds in the soil and irrigate the seeds, it is necessary for the output end of the sowing part 2 to be adapted to the position of the nozzle 77, that is, the output end of the sowing part 2 moves along with the movement of the nozzle 77. It is necessary to continue to disclose the specific structure of the lifting mechanism 8. Therefore, as Figure 3As shown in the figure, the lifting mechanism 8 further includes a connecting plate 83. One end of the connecting plate 83 close to the mounting plate 81 is fixedly arranged on the mounting plate 81, and the other end of the connecting plate 83 away from the mounting plate 81 is fixedly connected to the output end of the seeding part 2. By the movement of the mounting plate 81 as the cylinder 82 extends or contracts, the connecting plate 83 is driven to move, and further the output end of the seeding part 2 is driven to move, so that the output end of the seeding part 2 moves along with the movement of the nozzle 77.

[0047] In summary, the overall working principle of the present invention is as follows:

[0048] When the seeding device needs to be used for seeding, the seeding device is installed on a traction device (such as a tractor, etc.), and the traction device is used to drive the seeding device to move to complete seeding. The specific process is as follows:

[0049] The rotary tillage part 1 breaks and turns over the soil to make the soil loose, and then the seeding part 2 sows the seeds in the soil. When fertilization is required, first prepare liquid fertilizer. The top of the liquid fertilizer barrel 4 is provided with a barrel cover, and the barrel cover can be opened to pour the liquid fertilizer into the liquid fertilizer barrel 4, or solid fertilizer and clean water are put into the liquid fertilizer barrel 4 together to start the production of liquid fertilizer: start the motor 53, the motor 53 rotates by itself to generate driving force, drive the connected stirring shaft 51 to rotate, and then drive the gear 54 to rotate, and then drive other stirring shafts 51 to rotate around the axis, and then drive a plurality of stirring blades 52 to rotate. The rotation of the stirring blades 52 can fully stir the liquid fertilizer;

[0050] Then the liquid fertilizer is discharged from the liquid fertilizer barrel 4 into the soil for fertilization. Start the water pump 71, and the liquid fertilizer in the liquid fertilizer barrel 4 continuously enters the water pump 71 through the first water pipe 72, flows through the flow meter 73, then through the pipe network 74, the hose 75 and the U-shaped water pipe 76, and then sprays out from the nozzle 77 to both sides of the sown seeds, thus completing fertilization;

[0051] When the liquid fertilizer needs to be heated, start the heating pipe 62 to generate heat by itself to heat the liquid fertilizer in the liquid fertilizer barrel 4. The heating pipe 62 heats the liquid fertilizer in the liquid fertilizer barrel 4 to raise the temperature of the liquid fertilizer to the temperature required for the growth of the seeds.
