Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a monitoring system for controlling precision seeding and fertilization. Background Technology

[0002] Seed sowing and fertilization require a seeder. The working principle of a seeder is to use mechanical and physical principles to sow seeds appropriately. Seed distribution is carried out mechanically, with seeds being distributed into the soil through the seed tube, seed wheel, and seed metering device, ensuring even sowing. The seeder also has the function of controlling the sowing depth to ensure that the seeds are correctly placed in the soil. After sowing, the fertilization metering device can be used to complete fertilization and subsequent covering work to ensure the seed growth environment. Seed sowing can significantly improve work efficiency and reduce labor and time costs.

[0003] In traditional sowing operations, the seeding bin and fertilizer bin of a seeder are independent. Because different crops have varying requirements for the ratio of fertilizer to seeds, it is often difficult to match the total amount of seeds and fertilizer. In actual operation, it is very easy to encounter situations where seeds are sown but a large amount of fertilizer remains, or fertilizer is exhausted but a large amount of seeds remain. This forces operators to frequently replenish fertilizer or seeds manually during subsequent sowing processes, greatly extending the working time and increasing the labor intensity. Utility Model Content

[0004] The purpose of this invention is to provide a precision seeding and fertilization monitoring system to solve the problems mentioned in the background art, such as the different fertilizer requirements and seeding ratios of different crops, which often lead to a mismatch between the total amount of seeds and fertilizer in the storage, resulting in a surplus and the need for frequent manual replenishment, which increases the working time and labor intensity.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A precision seeding and fertilization monitoring system includes a seeding and fertilization device for precision seeding, a replenishment and temporary storage device, a liquid level sensor, a temporary storage and conveying device, and a controller. The seeding and fertilization device includes a seeding box and a fertilizer box. The liquid level sensor is distributed on the inner wall below one side of the seeding box and the fertilizer box. The seeding box is connected to one side of the fertilizer box. A quantitative seeding mechanism is connected to the bottom of the seeding box discharge port. A seeding discharge pipe is connected to the bottom of the seeding box discharge port outside the quantitative seeding mechanism. A discharge plate is connected to the bottom of the fertilizer box discharge port via a rotating shaft. A quantitative fertilizer weight sensor is connected to the bottom of the discharge plate. A fertilizer discharge pipe is connected to the bottom of the fertilizer box discharge port below the discharge plate.

[0007] Preferably, the quantitative sowing mechanism includes a sowing shaft located inside the sowing feed tube at the bottom of the sowing box feed inlet. Three sets of sowing grooves are provided on the outer circumferential wall of the sowing shaft. One end of the sowing shaft is connected to the inner wall of the sowing box via a bearing seat. The other end of the sowing shaft extends through the sowing box housing to its outside and is connected to a sowing motor. A precision sowing adjustment plate is provided on the outer circumferential wall of the sowing shaft. The precision sowing adjustment plate includes a precision material adjustment plate body that slides and engages on the outer circumferential wall of the sowing shaft and an adjustment horizontal plate body located at the bottom of the sowing box feed inlet. One end of the adjustment horizontal plate body extends through the sowing box housing to its outside. The top of the precision material adjustment plate body is fixed to the end of the adjustment horizontal plate body located inside the sowing box. When the adjustment horizontal plate body moves at the bottom of the feed inlet inside the sowing box, the precision material adjustment plate body moves accordingly.

[0008] Preferably, the supplementary storage device is symmetrically arranged on the outer wall of the seed box and the fertilizer box near the outside. The supplementary storage device includes a surplus seed storage box and a surplus fertilizer storage box. The surplus seed storage box is located on the outer wall below the seed box, and the surplus fertilizer storage box is located on the outer wall below the fertilizer box.

[0009] Preferably, a check valve is installed on the outer wall of both the seeding box and the fertilizer box near the discharge port.

[0010] Preferably, the temporary storage and conveying device includes a temporary storage pneumatic conveying feed pump, a temporary storage and conveying feed pipe, a supplementary conveying discharge pipe, and a supplementary pneumatic conveying discharge pump. The air inlet of the temporary storage pneumatic conveying feed pump is respectively installed on the outer wall of the seed box and the fertilizer box outside the check valve. The air outlet of the temporary storage pneumatic conveying feed pump on the outer wall of the seed box is connected to the top of the excess seed storage box through the temporary storage and conveying feed pipe. The air outlet of the temporary storage pneumatic conveying feed pump on the outer wall of the fertilizer box is connected to the top of the excess fertilizer storage box through the temporary storage and conveying feed pipe. The bottom discharge ports of the excess seed storage box and the excess fertilizer storage box are respectively connected to the supplementary conveying discharge pipe through the supplementary pneumatic conveying discharge pump. The supplementary conveying discharge pipe is connected to the top outer wall of the corresponding seed box and fertilizer box.

[0011] Preferably, the liquid level sensor is electrically connected to the controller via a wire, and the controller is electrically connected to the temporary storage pneumatic conveying feed pump and the supplementary pneumatic conveying discharge pump connected to the excess seed storage box and the excess fertilizer storage box via wires, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Through a quantitative sowing mechanism and a quantitative fertilizer weight sensor, the system can accurately control the amount of seeds and fertilizer applied. The sowing trough on the sowing shaft and the adjustable precision sowing adjustment plate can adjust the sowing amount according to actual needs. The weight sensor at the bottom of the fertilizer box discharge plate can accurately control the amount of fertilizer dispensed, ensuring that different crops can obtain the appropriate ratio of seeds and fertilizers when sowing, greatly improving the accuracy of sowing and fertilization, and providing a good foundation for crop growth.

[0014] 2. The liquid level sensor monitors the remaining material in the seed box and fertilizer box in real time and transmits the signal to the controller. When the material is nearly exhausted and there is material remaining, the controller automatically starts the temporary storage and conveying device. The temporary storage pneumatic conveying feed pump transports the remaining material to the corresponding surplus seed temporary storage box or surplus fertilizer temporary storage box. When it is necessary to replenish the material, the replenishment pneumatic conveying discharge pump can send the material in the temporary storage box back to the seed box or fertilizer box, realizing the automatic allocation and recycling of materials. This effectively solves the problem of the difficulty in matching the total amount of seeds and fertilizers and avoids the trouble of frequent manual replenishment of materials.

[0015] 3. The system's automation function reduces manual intervention, eliminating the need for operators to frequently monitor and manually replenish the materials in the seeding and fertilizing boxes. This significantly shortens the operation time, improves the overall efficiency of sowing and fertilizing operations, reduces labor intensity, and makes sowing and fertilizing work more efficient and convenient.

[0016] 4. The supplementary temporary storage devices are symmetrically arranged on the outer walls of the seeding box and fertilizer box. The layout is compact and reasonable, without taking up too much space. The check valve effectively prevents material backflow, ensuring the stability and reliability of the system operation, and further improving the practicality and durability of the system.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0027] Please see the appendix Figure 1-7As shown, a precision seeding and fertilization monitoring system includes a seeding and fertilization device 1, a replenishment and storage device 2, a liquid level sensor, a temporary storage and conveying device 3, and a controller. The seeding and fertilization device 1 includes a seeding box 11 and a fertilizer box 12. The seeding box 11 is used to hold seeds, and the fertilizer box 12 is used to hold fertilizer. Liquid level sensors are distributed on the lower inner wall of one side of the seeding box 11 and the fertilizer box 12. The liquid level sensors are used to monitor the amount of seeds and fertilizer in the seeding box 11 and the fertilizer box 12 in real time to ensure the accuracy of seeding and fertilization. The controller automatically adjusts the frequency and amount of seeding and fertilization by collecting data from the liquid level sensors to meet the requirements of precision agriculture, thereby effectively improving crop yield and quality. The seeding box 11 is connected to the device 12. On one side of the fertilizer box 12, the seed box 11 is located on the outer wall of the fertilizer box 12. The layout is compact and reasonable, not occupying too much space, and facilitating the addition of seeds and fertilizer. A quantitative seeding mechanism 13 is connected to the bottom of the seed box 11's discharge port for precision seeding. A seeding discharge pipe 14 is connected to the bottom of the seed box 11's discharge port outside the quantitative seeding mechanism 13, allowing the precision-discharged seeds to enter the soil through the seeding discharge pipe 14. A discharge plate 15 is connected to the bottom of the fertilizer box 12's discharge port via a rotating shaft. The rotating shaft is connected to an external opening and closing drive motor, allowing the discharge plate 15 to open and close. A quantitative fertilizer weight sensor is connected to the bottom of the discharge plate 15. A fertilizer discharge device is connected to the bottom of the fertilizer box 12's discharge port below the discharge plate 15. The quantitative sowing mechanism 13 includes a sowing shaft 131 located inside the sowing feed pipe 14 at the bottom of the sowing box 11's feed inlet. Three sets of sowing troughs 132 are provided on the outer circumferential wall of the sowing shaft 131. The sowing troughs 132 are used to hold individual seeds for precision sowing. One end of the sowing shaft 131 is connected to the inner wall of the sowing box 11 via a bearing seat, and the other end extends through the shell of the sowing box 11 to its exterior and is connected to a sowing motor 133. When the sowing motor 133 drives the sowing shaft 131 to rotate, the three sets of sowing troughs 132 rotate evenly, causing the seeds to fall sequentially into the sowing feed pipe 14. The speed of the sowing motor 133 is adjustable to adapt to the sowing needs of different crops. Through precise control by a controller, the seeds during the sowing process are... The quantity and spacing can be precisely adjusted to ensure that each seed receives optimal growth space. A precision seeding adjustment plate 134 is provided on the outer circumferential wall of the seeding shaft 131. The precision seeding adjustment plate 134 includes a precision material adjustment plate body 135 that slides and engages on the outer circumferential wall of the seeding shaft 131 and an adjustment horizontal plate body 136 located at the bottom of the feed inlet of the seeding box 11. One end of the adjustment horizontal plate body 136 extends through the shell of the seeding box 11 to its outside. The top of the precision material adjustment plate body 135 is fixed to the end of the adjustment horizontal plate body 136 located inside the seeding box 11. When the adjustment horizontal plate body 136 moves at the bottom of the feed inlet inside the seeding box 11, the precision material adjustment plate body 135 moves along with the adjustment horizontal plate body 136. When the bottom position of the adjustment horizontal plate body 136 at the feed inlet moves...The number and size of the seeding troughs 132 on the feed regulating plate 135 change accordingly, thereby achieving precise control of the seeding amount. The three sets of seeding troughs 132 on the seeding shaft 131 can dispense different amounts of seeds by adjusting the movement of the feed regulating plate 135.

[0028] In use, seeds are loaded into the seeding box 11 and fertilizer into the fertilizer box 12. The liquid level sensor starts monitoring the amount of material in both boxes in real time and transmits the data to the controller. The seeding motor 133 starts, driving the seeding shaft 131 to rotate. The three sets of seeding troughs 132 on the outer circumference of the seeding shaft 131 rotate sequentially to the bottom of the feed inlet of the seeding box 11, and individual seeds fall into the seeding trough 132. As the seeding shaft 131 continues to rotate, the seeding trough 132 containing seeds rotates to the position of the seeding feed pipe 14, and the seeds fall into the soil through the seeding feed pipe 14. If it is necessary to adjust the seeding amount, the horizontal plate 136 can be adjusted externally to keep it within the seeding box 11. The bottom of the feed inlet is displaced, which drives the fine material adjustment plate 135 to move, changing the quantity and size of the feed in the seeding trough 132, thus achieving precise control of the seeding amount. The discharge plate 15 at the bottom of the feed inlet of the fertilizer box 12 can be opened and closed under the action of the rotating shaft motor. The fertilizer falls through the discharge plate 15. The quantitative fertilizer weight sensor connected to the bottom of the discharge plate 15 monitors the fertilizer weight in real time to ensure accurate fertilizer application. The fertilizer is applied to the soil through the fertilizer feeding pipe 16. The liquid level sensor continuously monitors the material quantity in the seeding box 11 and the fertilizer box 12. When the material in one box is nearly exhausted, the controller receives the liquid level sensor signal, receives the data, and processes it.

[0029] The sowing and fertilization device 1 in this application includes a sowing box 11 and a fertilizer box 12. Liquid level sensors are installed on the lower inner walls of both boxes near the discharge port to monitor the remaining material in the box in real time. The bottom of the sowing box 11 is connected to a quantitative sowing mechanism 13, which accurately controls the amount of seeds fed through a sowing shaft 131, a sowing trough 132, and an adjustable precision sowing adjustment plate 134. The bottom of the fertilizer box 12 is connected to a discharge plate 15 through a rotating shaft, and a quantitative fertilizer weight sensor is installed at the bottom of the discharge plate 15 to accurately control the amount of fertilizer applied, greatly improving the accuracy of sowing and fertilization and providing a good foundation for crop growth.

[0030] Please see the appendix Figure 1 , 4As shown in Figure 7, the supplementary storage device 2 is symmetrically arranged on the outer wall of the seeding box 11 and the fertilizer box 12 near the outside. It includes a surplus seed storage box 21 located below the seeding box 11 and a surplus fertilizer storage box 22 located below the fertilizer box 12. This layout is compact and reasonable, does not occupy too much extra space, and facilitates the management and retrieval of the stored materials. The surplus seed storage box 21 is located on the outer wall below the seeding box 11, and the surplus fertilizer storage box 22 is located on the outer wall below the fertilizer box 12. A check valve 17 is connected through the outer wall of the seeding box 11 and the fertilizer box 12 near the discharge port. The check valve 17 is used to prevent the seeds and fertilizer inside the seeding box 11 and the fertilizer box 12 from flowing back into the storage box, ensuring the purity and accurate feeding of the materials, maintaining the accurate feeding of the system, and providing a guarantee for the stability of the entire seeding and fertilization process. The temporary storage and conveying device 3 includes a temporary storage pneumatic conveying feed pump 31, a temporary storage and conveying feed pipe 32, a supplementary conveying discharge pipe 33, and a supplementary pneumatic conveying discharge pump 34. The air inlet of the temporary storage pneumatic conveying feed pump 31 is respectively installed on the outer wall of the seed box 11 and the fertilizer box 12 outside the check valve 17. The air outlet of the temporary storage pneumatic conveying feed pump 31 on the outer wall of the seed box 11 is connected to the top of the excess seed storage box 21 through the temporary storage and conveying feed pipe 32. The air outlet of the temporary storage pneumatic conveying feed pump 31 on the outer wall of the fertilizer box 12 is connected to the top of the excess fertilizer storage box 22 through the temporary storage and conveying feed pipe 32. The bottom discharge ports of the excess seed storage box 21 and the excess fertilizer storage box 22 are respectively connected to the supplementary conveying discharge pipe 33 through the supplementary pneumatic conveying discharge pump 34. The supplementary conveying discharge pipe 33 is connected to the top outer wall of the corresponding seed box 11 and fertilizer box 12.

[0031] The air inlet of the temporary storage pneumatic conveying feed pump 31 is installed on the outer wall of the seed box 11 and fertilizer box 12 outside the check valve 17. Its air outlet is connected to the top of the excess seed storage box 21 and the top of the excess fertilizer storage box 22 through the temporary storage conveying feed pipe 32, respectively. When the liquid level sensor detects that the material in the seed box 11 or fertilizer box 12 is about to be exhausted, the controller receives the signal and starts the temporary storage pneumatic conveying feed pump 31 to convey the remaining material to the corresponding excess seed storage box 21 or excess fertilizer storage box 22 through the temporary storage conveying feed pipe 32 via pneumatic conveying.

[0032] Conversely, when materials need to be replenished, the bottom discharge ports of the excess seed storage box 21 and the excess fertilizer storage box 22 are connected to the replenishment conveying pipe 33 through the replenishment pneumatic conveying pump 34. The replenishment conveying pipe 33 is then connected to the top outer wall of the corresponding seed box 11 and fertilizer box 12. At this time, the controller controls the replenishment pneumatic conveying pump 34 to start, and sends the materials in the storage box back to the seed box 11 or fertilizer box 12, thus completing the recycling and replenishment of materials.

[0033] The liquid level sensor is electrically connected to the controller via a wire. The liquid level sensor monitors the remaining material in the seed box 11 and fertilizer box 12 in real time and transmits the data to the controller via the wire. The controller is electrically connected to the temporary storage pneumatic conveying feed pump 31 and the supplementary pneumatic conveying discharge pump 34 connected to the excess seed storage box 21 and the excess fertilizer storage box 22 via wires. The controller is also electrically connected to the temporary storage pneumatic conveying feed pump 31 and the supplementary pneumatic conveying discharge pump 34 connected to the excess seed storage box 21 and the excess fertilizer storage box 22 via wires. Based on the data from the liquid level sensor, the controller precisely controls the start and stop of the temporary storage pneumatic conveying feed pump 31 and the supplementary pneumatic conveying discharge pump 34, realizing the automation and intelligence of the entire material storage and conveying process, which greatly improves the operating efficiency and reliability of the precision seeding and fertilization monitoring system.

[0034] In use, when the material level in the seeding box 11 or fertilizer box 12 is lower than the set replenishment threshold, the controller, based on the data transmitted by the liquid level sensor, starts the replenishment pneumatic conveying pump 34 connected to the bottom discharge port of the excess seed storage box 21 or excess fertilizer storage box 22. The replenishment pneumatic conveying pump 34 operates, sending the seeds or fertilizer in the storage box back to the top of the corresponding seeding box 11 or fertilizer box 12 through the replenishment conveying discharge pipe 33, thereby replenishing the material and ensuring the continuous operation of seeding and fertilization. Throughout the operation, the liquid level sensor continuously monitors the remaining material level and continuously feeds back data to the controller. Based on this real-time data, the controller precisely controls the start and stop of the storage pneumatic conveying feed pump 31 and the replenishment pneumatic conveying discharge pump 34. Through this automated control method, the efficient and intelligent recycling and replenishment of materials between the seeding box 11, fertilizer box 12 and storage box is achieved, ensuring the stable and reliable operation of the precision seeding and fertilization monitoring system and significantly improving the efficiency and accuracy of seeding and fertilization operations.

[0035] The system's automation reduces manual intervention, eliminating the need for operators to frequently monitor and manually replenish the materials in the seeding and fertilizing boxes. This significantly shortens operation time, improves the overall efficiency of sowing and fertilizing operations, reduces labor intensity, and makes sowing and fertilizing work more efficient and convenient.
