Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to an integrated field fertilizer applicator. Background Technology

[0002] A fertilizer applicator is an agricultural machine used to spread fertilizer in farmland. Its main purpose is to improve the efficiency and uniformity of fertilization, reduce the intensity and workload of manual labor, avoid missing the best time for fertilizing crops, and optimize the efficiency of crop fertilizer use.

[0003] Fertilizer applicators can quickly spread fertilizer in farmland, much faster than manual fertilization, especially in large-scale farming, significantly improving work efficiency. Fertilizer applicators can evenly spread fertilizer into the soil according to a preset amount, helping crops to absorb nutrients evenly and improving crop yield and quality. However, with the rapid development of agricultural automation in my country, farmers have put forward higher requirements for fertilization systems, especially for the structure and fertilization functions of fertilizer applicators. Therefore, a large-scale integrated fertilizer applicator is needed.

[0004] The existing integrated fertilizer applicator has the following shortcomings:

[0005] Most fertilizer applicators on the market today have external pipelines and water pumps that are exposed to the elements. In this case, the pipelines and water pumps are easily damaged by the external environment. Most of them use a quantitative and timed fertilization mode, which cannot meet the needs of farmers to apply fertilizer according to different land areas at different speeds. This means that when fertilizing some special soils, it is not possible to ensure that the amount of fertilizer applied is in a standard state, which can easily lead to fertilizer waste.

[0006] Therefore, we proposed an integrated field fertilizer applicator to solve the problems mentioned above. Utility Model Content

[0007] The water pump is started via the touchscreen. It draws liquid from a connecting pipe that leads to an ejector. The ejector is connected to the inlet and a check valve. A float flow meter is connected to the check valve, followed by a turbine flow meter and an electric ball valve. The electric ball valve is connected to the fertilizer inlet, allowing the pump to draw liquid from both inlets, mix them, and discharge them through the fertilizer outlet for fertilization. An EC sensor and a pH sensor are installed on the pipe at the bottom of the ejector to monitor fertilizer concentration and pH. If the concentration is too high, a warning will be displayed on the touchscreen. The operator can adjust the opening of the electric ball valve via the touchscreen to reduce the fertilizer application rate. Parameters can also be set via the touchscreen. The PLC calculates and outputs to drive the frequency converter, controlling the water pump speed to adjust the fertilizer dosage. A float flow meter monitors the fertilization rate, while a turbine flow meter measures the fertilization rate and total amount, ensuring that fertilizer concentration is controlled as needed and preventing resource waste. Considering that the equipment is often used outdoors and is susceptible to damage from environmental factors, the chassis is equipped with a protective shell that is tightly sealed with a cover, providing dustproof, rainproof, and sunproof protection. An internal protective partition is installed to isolate the electrical components and pipelines, preventing leakage from damaging the electrical components. The bottom of the chassis is equipped with casters for easy movement of the equipment, enhancing its protective performance and extending its service life, thus solving the problems mentioned in the background technology.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: an integrated field fertilizer applicator, comprising a chassis, a support frame fixedly connected to the inner side of the chassis, a water pump fixedly connected to the top of the support frame, a fertilizer outlet connected to the output end of the water pump, a connecting pipe connected to the input end of the water pump, a connecting pipe connected to the other end of the connecting pipe, an ejector fixedly connected to the connecting pipe, another connecting pipe fixedly connected to the ejector, an EC sensor fixedly connected to the bottom of the connecting pipe, a pH sensor disposed on the outer side of the EC sensor, the pH sensor fixedly connected to the connecting pipe, a water inlet connected to the connecting pipe, a connecting pipe connected to the outer side of the ejector, a check valve fixedly connected to the connecting pipe, a float flow meter fixedly connected to the check valve, a turbine flow meter fixedly connected to the connecting pipe, another connecting pipe fixedly connected to the turbine flow meter, an electric ball valve fixedly connected to the connecting pipe, a fertilizer inlet fixedly connected to the electric ball valve, and a protective mechanism disposed at the top of the chassis.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, the water pump is started via a touchscreen. The water pump draws liquid from the connecting pipe, which is connected to an ejector. The ejector is connected to the inlet and a check valve. The check valve is connected to a float flow meter, which is then connected to a turbine flow meter and an electric ball valve.

[0028] The overall effect of embodiment 2 is as follows: the protective shell 201 and the protective cover 204 can prevent outdoor dust and rainwater from corroding the inside of the equipment, and can also prevent the internal components of the equipment from overheating and being damaged due to sun exposure. The protective partition 203 isolates the electrical parts from the pipeline parts to prevent the electrical parts from being damaged when the pipeline leaks. The casters 205 at the bottom of the chassis 1 can make the equipment easy to move.

[0029] Example 3, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fixing plate 28 is fixedly connected to the inner side of the protective partition 203, and a residual current device (RCD) 17 is fixedly connected to the outer side of the fixing plate 28. A 4G communication circuit board 29 is installed at the bottom of the RCD 17, a phase sequence protector 18 is installed on the outer side of the RCD 17, and a power module MDR-40-2419 is installed on the outer side of the phase sequence protector 18. A touch screen 26 is fixedly connected to the inner side of the protective cover 204, a PLC 20 is installed on the outer side of the power module MDR-40-2419, multiple relays 21 are installed on the outer side of the PLC 20, a circuit board 24 is installed at the bottom of the relays 21, a transformer controller 23 is installed on the outer side of the circuit board 24, multiple AC contactors 22 are installed on the outer side of the transformer controller 23, and a circuit board 24 is installed at the bottom of the AC contactors 22. There are multiple terminal blocks 25, and multiple thermal overload relays 27 are installed at the bottom of the AC contactor 22. The phase sequence protector 18, power module MDR-40-2419, PLC 20, relay 21, AC contactor 22, transformer controller 23, circuit board 24, terminal blocks 25 and thermal overload relays 27 are all fixedly connected to the mounting plate 28 in sequence. The data detected by EC sensor 14, PH sensor 15, float flow meter 10 and turbine flow meter 11 are uploaded to the cloud via 4G cellular network MQTT protocol. Drainage holes are designed under the chassis 1, and the heat dissipation holes 202 adopt a louvered window design. The internal pipeline connection method adopts the union connection. The EC sensor 14 and PH sensor 15 are installed perpendicular to the bottom of the pipeline.

[0030] The overall effect of embodiment 3 is as follows: the touch screen 26 is used to display detection data and control equipment information. Sensitive options on it are started and stopped using a password, effectively preventing accidental touches and other unexpected situations. The touch screen 26 is fixed to the front of the housing and connected to the internal components via ribbon cables. The terminal block 25 is used for power cable connection, motor cable connection, and sensor cable connection. The phase sequence protector 18 is used for high voltage protection, low voltage protection, and phase reversal protection. The relay 21, AC contactor 22, and thermal overload relay 27 are used for automatic control and protection of the three-phase motor. The touch screen 26 can be set with a timer. The mixing function is timed; the user sets the mixing duration, and starts mixing by clicking the mixing start button on the touchscreen 26. Mixing automatically stops after the set time. An error handling function can also be set, including protection against power failure, flow meter stall, fertilization overtime, and water pump 4 malfunction. If the three-phase input voltage exceeds the set upper and lower limits, the power module outputs a switch fault signal, the PLC 20 detects the fault, stops all operations, and reports a power failure. If the fertilizer applicator suddenly detects no flow signal during operation, and there is still no flow signal within three minutes, fertilization operation stops and a flow meter stall fault is reported. To prevent over-fertilization, if the fertilizer applicator cannot adjust the fertilization speed to the target speed during operation, and if the target flow rate cannot be adjusted within five minutes, fertilization operation will stop and a timeout fault will be reported. This prevents excessive irrigation time due to prolonged fertilization. During fertilization operation, if the fertilizer pump stalls and the overcurrent protection mechanism is activated, the thermal overload relay module 27 will output a switch fault signal. PLC 20 will detect the fault, stop all operations, and report a fertilizer pump fault. Furthermore, both the touchscreen 26 and the 4G communication circuit board 29 have firmware upgrade functions. Maintenance personnel can upgrade the firmware via the platform. The fertilizer applicator downloads firmware via HTTP interface protocol, and uploads the latest version number after upgrade. A drainage hole is designed below the chassis 1 to prevent water leakage from the pipes and causing circuit failures. The equipment's heat dissipation vent 202 adopts a louvered window design to effectively reduce the internal temperature. The internal pipe connections use union connections for easy maintenance. The EC sensor 14 and PH sensor 15 are installed perpendicular to the lower part of the pipes to stably test fertilizer EC and PH data. The PLC 20 drives the frequency converter speed by comparing the feedback fertilization speed with the calculated fertilization speed.

[0031] The working principle of the entire device is as follows: When fertilizer needs to be applied to crops, the water pump 4 is first turned on via the touch screen 26. After the water pump 4 starts, it draws liquid from the connecting pipe 6 fixed at its input end. Since the connecting pipe 6 is connected to the ejector 7 via the connecting pipe 16, and the ejector 7 is connected to the inlet 8 and the check valve 9 via the connecting pipe 16, the check valve 9 is connected to the float flow meter 10, the float flow meter 10 is connected to the turbine flow meter 11 via the connecting pipe 16, the turbine flow meter 11 is connected to the electric ball valve 12 via the connecting pipe 16, and the electric ball valve 12 is connected to the fertilizer inlet 13, the water pump 4 draws water from the fertilizer inlet 13 and the inlet 8 via the connecting pipe 6. The water drawn into the inlet 8 by the water pump 4 and the fertilizer drawn into the fertilizer inlet 13 are mixed to form the final waste. The fertilizer passes through the water pump 4 and is eventually discharged from the fertilizer outlet 5. During this process, the EC sensor 14 and pH sensor 15 on the connecting pipe 16 at the bottom of the ejector 7 detect whether the concentration and acidity / alkalinity of the fertilizer flowing through this area meet the requirements of the land and crops. If the concentration is too high, this information is transmitted to the touch screen 26. After receiving the information, the user uses the touch screen 26 to control the opening of the electric ball valve 12 to reduce the amount of fertilizer entering. The float flow meter 10 is used to observe the current fertilization rate, and the turbine flow meter 11 is used to measure the fertilization rate and amount so that the work can be reviewed and statistically analyzed after the work is completed. This allows the concentration of fertilizer to be controlled according to the actual conditions of the soil and crops, avoiding waste caused by overuse of fertilizer.

[0032] Since the working environment is often outdoors, the equipment is easily damaged by complex and changing environments. Therefore, a protective shell 201 is provided on the chassis 1. The protective shell 201 is tightly connected to the protective cover 204 on it, which can prevent outdoor dust and rainwater from corroding the inside of the equipment, and can also prevent the internal components of the equipment from overheating and being damaged due to sun exposure. The protective partition 203 fixed inside the protective shell 201 isolates the electrical parts from the pipeline parts, so as to avoid the problem of the electrical parts being damaged when the pipeline leaks, which would lead to greater damage to the equipment. The casters 205 at the bottom of the chassis 1 can make the equipment easy to move, thereby protecting the equipment and extending its service life.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
