Description

Technical Field

[0001] This utility model relates to the technical field of agricultural fertilization, and in particular to a gas-separating reverse pressure fertilizer applicator. Background Technology

[0002] A fertilizer applicator is a device used in agricultural irrigation systems to precisely and evenly inject fertilizer (or pesticide) into the irrigation water flow.

[0003] In related technologies, existing fertilizer applicators, such as Venturi fertilizer applicators, differential pressure fertilizer tanks, and pump systems equipped with simple venting valves, generally face several major technical bottlenecks when dealing with the problem of air mixed in the fertilizer solution. Firstly, their venting mechanisms are mostly passive (such as float valves) or manually operated, which are prone to failure due to fertilizer crystallization and blockage, resulting in incomplete venting. Secondly, the venting process causes drastic fluctuations in system pressure: the pressure drops sharply during venting and rises again afterward. This instability directly leads to pulsating output flow, making it impossible to achieve constant flow fertilization and severely affecting the fertilization effect of drip irrigation and other applications requiring extremely high uniformity. Furthermore, they cannot adapt to changes in gas content; too much gas may cause excessive pressure and damage the system, while too little gas results in insufficient back pressure and weak liquid output, making it impossible to maintain an efficient and stable outlet flow rate. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a gas-separating backpressure fertilizer applicator, which adopts an active pressure management system. Through a pressure vessel, it actively collects gas and uses the gas pressure to convert the gas into a precisely adjustable and stable gas pressure piston, providing a smooth driving force for the liquid flow.

[0006] To achieve the above objectives, this utility model proposes a gas separation backpressure fertilizer applicator, comprising a base plate, a power module, a fertilizer pump, an inlet pipe, an outlet pipe, and a backpressure exhaust mechanism. The power module and the fertilizer pump are mounted on the base plate. The inlet pipe is located at the input end of the fertilizer pump, and the outlet pipe is connected to the output end of the fertilizer pump via the backpressure exhaust mechanism. The backpressure exhaust mechanism includes a connecting pipe, a pressure cylinder, a separation component, and a pressure regulating component. The pressure cylinder is connected to the output end of the fertilizer pump via the connecting pipe and communicates with the outlet pipe. The separation component is located inside the pressure cylinder, and the pressure regulating component is located on the pressure cylinder.

[0007] This utility model discloses a gas-separating back-pressure fertilizer applicator, which integrates gas-liquid separation, back pressure formation, automatic pressure relief, and adjustable pressure into a pressure stabilizing system. It disperses and delivers liquid fertilizer containing gas into a pressure cylinder, promotes gas-liquid separation within the pressure cylinder, actively collects gas, and, with the help of a pressurizing device and the pressure of the collected gas, converts the gas into a precisely adjustable and stable gas pressure piston, providing a smooth driving force for the liquid flow.

[0008] In addition, the gas-separating reverse-pressure fertilizer applicator proposed above according to this utility model may also have the following additional technical features: Specifically, the separation assembly includes a first partition and a second partition. The first partition is disposed at the connection between the liquid inlet pipe and the pressure cylinder and has multiple first through holes. The second partition is disposed on the pressure cylinder and divides the pressure cylinder into a pressure chamber and a separation chamber. The second partition has multiple second through holes.

[0009] Specifically, the pressure regulating assembly includes a pressurizing device, a pressure sensing element, and a pressure relief valve. The pressurizing device is disposed on the pressure cylinder and communicates with the pressure chamber. The pressure sensing element is disposed on the pressure cylinder and located inside the pressure chamber. The pressure relief valve is disposed on the pressure cylinder and communicates with the pressure chamber.

[0010] Specifically, a first rubber valve is provided in a plurality of first through holes, and a second rubber valve is provided in a plurality of second through holes.

[0011] Specifically, the bottom of the pressure cylinder is tapered.

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The following description, in conjunction with the accompanying drawings, describes a gas-separating reverse-pressure fertilizer applicator according to an embodiment of the present invention.

[0017] like Figures 1-3 As shown, a gas-separating backpressure fertilizer applicator according to an embodiment of the present invention may include a base plate 1, a power module 2, a fertilizer pump 3, an inlet pipe 4, an outlet pipe 5, and a backpressure exhaust mechanism 6.

[0018] The power module 2 is mounted on the base plate 1, the fertilizer pump 3 is mounted on the base plate 1, the inlet pipe 4 is mounted on the input end of the fertilizer pump 3, and the outlet pipe 5 is mounted on the output end of the fertilizer pump 3 through the back pressure exhaust mechanism 6.

[0019] It should be noted that the base plate 1 described in this embodiment has positioning holes at its corners for fixing the device. At the same time, the base plate 1 can stably support the power module 2, fertilizer pump 3, liquid inlet pipe 4, liquid outlet pipe 5 and back pressure exhaust mechanism 6.

[0020] The back pressure exhaust mechanism 6 includes a connecting pipe 61, a pressure cylinder 62, a separation component 63, and a pressure regulating component 64.

[0021] The pressure cylinder 62 is located at the output end of the fertilizer pump 3 via the connecting pipe 61 and is connected to the liquid outlet pipe 5. The separation component 63 is located inside the pressure cylinder 62, and the pressure regulating component 64 is located on the pressure cylinder 62.

[0022] It should be noted that in the above embodiment, the connecting pipe 61 is connected to the lower side wall of the pressure cylinder 62. The liquid fertilizer containing gas is pressurized and sent into the pressure cylinder 62 through the separation component 63 to promote gas-liquid separation and collect the gas. At the same time, the pressure regulating component 64 inside the pressure cylinder 62 is used to press down the liquid fertilizer in the opposite direction to the collected gas for output.

[0023] Specifically, during the actual fertilization process, the relevant personnel fix the base. In the initial state, the power module 2 is electrically connected to the fertilizer pump 3, the pressure detection element 642 and the pressurization device 641 respectively, and the internal pressure of the pressure chamber 621 is monitored by a microcontroller (not shown in the figure).

[0024] In use, the input end of the fertilizer pump 3 draws liquid fertilizer through the inlet pipe 4. When the liquid fertilizer is mixed with gas, it is transported by the fertilizer pump 3 and enters the pressure box through the connecting pipe 61. When it passes through the through hole inside the first partition 631, the liquid fertilizer is forced to flow and pressurized. When the liquid fertilizer is sprayed into the pressure cylinder 62, the gas floats up and is blocked by the second partition 632. When the pressure reaches a certain level, it enters the pressure chamber 621 through the second through hole 6321. The pressure detection element 642 monitors the pressure inside the pressure chamber 621. When the pressure is too high, it is discharged through the pressure relief valve 643. When the pressure is too low, air is pumped into the pressure chamber 621 through the pressurization device. Under stable conditions, the pressure cylinder 62 maintains a certain pressure, and the liquid fertilizer is discharged under pressure, thus realizing the stable delivery of liquid fertilizer.

[0025] In one embodiment of this utility model, such as Figure 3 As shown, the separation component 63 includes a first partition 631 and a second partition 632.

[0026] The first partition 631 is located at the connection between the liquid inlet pipe 4 and the pressure cylinder 62. The first partition 631 has multiple first through holes 6311. The second partition 632 is located on the pressure cylinder 62 and divides the pressure cylinder 62 into a pressure chamber 621 and a separation chamber 622. The second partition 632 has multiple second through holes 6321.

[0027] It should be noted that the first partition 631 and multiple first through holes 6311 proposed in the above embodiments are used to pressurize the flowing liquid fertilizer and promote gas-liquid separation. The second partition 632 and multiple second through holes 6321 are used to pressurize the flow of gas, so that the collected gas can be pressed downward in the pressure chamber 621 to promote stable output of liquid fertilizer.

[0028] In one embodiment of this utility model, such as Figure 2 and 3 As shown, the pressure regulating assembly 64 includes a pressurizing device 641, a pressure sensing element 642, and a pressure relief valve 643.

[0029] The pressurizing device 641 is mounted on the pressure cylinder 62 and connected to the pressure chamber 621. The pressure detection element 642 is mounted on the pressure cylinder 62 and located inside the pressure chamber 621. The pressure relief valve 643 is mounted on the pressure cylinder 62 and connected to the pressure chamber 621.

[0030] It should be noted that the pressurizing device 641 proposed in the above embodiment is an air pump, and the output end of the air pump is located inside the pressure chamber 621. A one-way valve is provided at the output end of the air pump to prevent the liquid level from rising and damaging the air pump. The pressure detection element 642 is a pressure sensor, and the pressure relief valve 643 and the pressurizing device 641 are adjusted by monitoring the air pressure inside the pressure chamber 621.

[0031] In one embodiment of this utility model, such as Figure 2 and 3 As shown, a first rubber valve 63111 is provided in a plurality of first through holes 6311, and a second rubber valve 6321 is provided in a plurality of second through holes 6321.

[0032] It should be noted that the first rubber valve 63111 and the second rubber valve 63211 described in this embodiment are used for pressure regulation of the first through hole 6311 and the second through hole 6321, respectively, which can pressurize the flow of the conveyed liquid fertilizer and gas.

[0033] In one embodiment of this utility model, such as Figure 2 and 3 As shown, the bottom of the pressure cylinder 62 is tapered.

[0034] It should be noted that the bottom of the pressure cylinder 62 described in this embodiment is tapered to reduce eddies and turbulence, avoid the formation of dead zones, and prevent fertilizer sedimentation and residue.

[0035] In summary, the gas-separating backpressure fertilizer applicator of this utility model adopts an active pressure management system. Through a pressure vessel, it actively collects gas and uses the gas pressure to convert the gas into a precisely adjustable and stable gas pressure piston, providing a smooth driving force for the liquid flow.
