Description

TECHNICAL FIELD

[0001] The utility model relates to water and fertilizer integration machine technical field, and specifically relates to water and fertilizer integration machine. BACKGROUND

[0002] In the development of modern agriculture, the movable water and fertilizer integration machine is widely used in various farmland scenes due to its precise fertilization and irrigation functions.

[0003] However, when the fertilizer solution liquid level in the movable water and fertilizer integration machine is in the 30%-70% interval, the product of the free liquid surface area and the liquid inertia moment reaches a peak, and the shaking energy density is as high as 3-5 times that of the full liquid state. Transportation stability becomes a prominent problem; during movement, slight jolting will cause the solution to produce violent reciprocating wave motion. This not only causes dynamic lateral forces to appear, affecting the stability of the overall center of gravity of the equipment, but also causes the liquid inertia impact to be amplified, causing a large impact on the structure of the equipment itself. Over time, the equipment parts are easily damaged, the service life of the equipment is shortened, and the maintenance cost is increased.

[0004] The existing movable water and fertilizer integration machine has limited control means for solution shaking in this state. Common sealing measures can only prevent solution leakage and cannot effectively suppress solution shaking. In summary, the movable water and fertilizer integration machine faces problems such as poor transportation stability and insufficient shaking control during movement, especially when the fertilizer solution is in a half-full state, and innovative technology is needed to optimize the design to meet the needs of modern agriculture for efficient and safe operation equipment. UTILITY MODEL CONTENTS

[0005] In view of the problems in the prior art, the utility model provides a water and fertilizer integration machine.

[0006] In order to solve the above technical problems, the utility model solves them through the following technical schemes:

[0007] The water and fertilizer integration machine comprises a transport vehicle and an integration machine main body, the integration machine main body is fixed on the transport vehicle, the integration machine main body comprises a mixing tank, an electric push rod is arranged on the top wall in the mixing tank, the lower end of the electric push rod is connected with a horizontal partition plate, and the outer wall of the horizontal partition plate is in close contact with the inner wall of the mixing tank; a vent hole is formed in the horizontal partition plate, and a sealing device for sealing the vent hole is further arranged on the horizontal partition plate.

[0008] The electric push rod extends or retracts, driving the horizontal partition plate connected therewith to move up and down in the mixing tank. By adjusting the position of the horizontal partition plate, the size of the space in the mixing tank containing the fertilizer solution can be changed, so that the solution is closer to the full liquid state during transportation, reducing the free liquid surface area and thus reducing the energy density of the shaking. When the electric push rod drives the horizontal partition plate to move, the vent hole is used to balance the air pressure of the upper and lower parts of the mixing tank, so as to avoid the influence of air pressure difference caused by the movement of the partition plate on the smooth movement. When the partition plate moves to the corresponding position, the sealing device closes the vent hole to prevent the solution from overflowing from the vent hole during transportation.

[0009] By adjusting the position of the horizontal partition plate by the electric push rod, the space distribution of the solution is changed, and the dynamic lateral force generated by shaking is reduced, thereby significantly improving the stability of the water and fertilizer integrated machine during transportation, ensuring the stability of the equipment during movement, reducing the risk of accidents such as overturning, and ensuring the safety of the operator and the surrounding environment.

[0010] As a preferred embodiment, the vent hole comprises an upper air guide hole and a lower floating cavity, the lower floating cavity is arranged below the upper air guide hole, and the aperture of the lower floating cavity is larger than that of the upper air guide hole; the sealing device comprises a floating sealing plug arranged in the lower floating cavity, and in a natural state, a gas flow channel is formed between the side wall of the floating sealing plug and the inner wall of the lower floating cavity for gas flow; when the floating sealing plug is affected by the liquid buoyancy, the floating sealing plug moves upward and its upper end surface is pressed against the upper air guide hole, thereby sealing the upper air guide hole.

[0011] During the process of the electric push rod driving the horizontal partition plate to move downward, the space of the upper and lower parts of the mixing tank changes, and the air pressure will be different; at this time, the vent hole plays a role, and the gas flow can pass through the gas flow channel and the upper vent hole, without hindering the flow of gas during air pressure balance.

[0012] When the horizontal partition plate continues to move downward, the floating sealing plug is affected by the buoyancy of the liquid below and moves upward; as the floating sealing plug moves upward, its upper end surface will gradually press against the upper air guide hole, thereby sealing the upper air guide hole and preventing the solution from overflowing from the vent hole.

[0013] As a preferred embodiment, the side wall of the floating sealing plug is provided with an axial guide rib, and the inner wall of the lower floating cavity is provided with a guide groove for the axial guide rib to extend into; when the floating sealing plug moves up and down in the lower floating cavity, the axial guide rib moves up and down in the guide groove.

[0014] During the operation of the integrated water and fertilizer machine, when the horizontal baffle moves downward, causing a change in the buoyancy of the liquid below on the floating seal plug, the floating seal plug will move up and down within the lower floating chamber. At this time, the axial guide ribs on the side wall of the floating seal plug tightly engage with the guide grooves on the inner wall of the lower floating chamber. The axial guide ribs are embedded in the guide grooves, and throughout the entire process of the floating seal plug moving upward under buoyancy and downward under decreasing buoyancy, the axial guide ribs always slide up and down axially within the guide grooves. This engagement provides a precise guiding path for the movement of the floating seal plug, ensuring that it can only move in a straight line along the axial direction, preventing deviation or wobbling during its up-and-down movement.

[0015] Preferably, two axial guide ribs are provided and symmetrically arranged on the side wall of the floating sealing plug, and two corresponding guide grooves are also provided.

[0016] Two symmetrically arranged axial guide ribs, in conjunction with corresponding guide grooves, can more precisely constrain the movement direction of the floating sealing plug compared to a single guide structure. This symmetrical design further reduces the possibility of the floating sealing plug shifting during its up-and-down movement, ensuring that it can achieve extremely precise pressure sealing with the upper air vent. This significantly improves the accuracy and reliability of the sealing operation, effectively preventing solution from overflowing from the vent, and providing stronger protection for the safety of the integrated water and fertilizer machine during transportation.

[0017] Preferably, a float ball is fixed to the lower end face of the floating sealing plug.

[0018] A float is fixed to the lower end face of the floating seal plug, greatly increasing the sensing area of ​​the sealing device for liquid buoyancy. Compared to relying solely on the buoyancy of the floating seal plug itself, the float can more sensitively sense changes in liquid buoyancy. This improved benefit to the floating seal plug allows it to more tightly press against the upper air vent.

[0019] Preferably, the mixing tank is equipped with an observation window.

[0020] The observation window on the mixing tank provides workers with a direct view of the internal conditions. As the electric actuator lowers the horizontal baffle, workers can directly observe its position within the tank through the window. This visual observation allows workers to determine whether the baffle has reached the correct position without the need for complex measuring tools or indirect feedback.

[0021] Preferably, the sidewalls of the horizontal partition are wrapped with rubber rings.

[0022] The rubber ring possesses excellent elasticity and flexibility, fitting snugly against the inner wall of the mixing tank. As the horizontal baffle moves, the rubber ring adapts to the shape of the tank's inner wall, maintaining constant contact. This not only ensures smooth movement of the horizontal baffle but also effectively fills the tiny gaps between the baffle and the tank's inner wall, preventing fertilizer solution leakage and providing a good seal.

[0030] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0031] Example

[0032] The mobile fertigation unit of this embodiment consists of a transport vehicle and a main unit, with the main unit fixed to the transport vehicle. The main unit mainly comprises two parts: a mixing tank 110 and control equipment.

[0033] like Figures 1-5As shown, an electric push rod 120 is installed on the top wall inside the mixing tank 110. The lower end of the electric push rod 120 is connected to a horizontal partition 130, and the outer wall of the horizontal partition 130 is tightly fitted to the inner wall of the mixing tank 110. The horizontal partition 130 is provided with a vent 140, which consists of an upper air guide hole 1401 and a lower floating cavity 1402 located below it. The diameter of the lower floating cavity 1402 is larger than that of the upper air guide hole 1401.

[0034] Meanwhile, the horizontal partition 130 is also equipped with a sealing device, which includes a floating sealing plug 150 disposed in the lower floating cavity 1402. In its natural state, an airflow channel is formed between the side wall of the floating sealing plug 150 and the inner wall of the lower floating cavity 1402 for airflow to pass through. Two axial guide ribs 160 are symmetrically arranged on the side wall of the floating sealing plug 150, and correspondingly, two guide grooves 170 are provided on the inner wall of the lower floating cavity 1402 for the axial guide ribs 160 to extend into. In addition, a float ball 1501 is fixed to the lower end face of the floating sealing plug 150. A rubber ring 1301 is wrapped around the side wall of the horizontal partition 130. An observation window 1101 is provided on the tank body of the mixing tank 110.

[0035] The control equipment is mainly electrical equipment used to precisely control components such as the electric actuator 120. For example, it adjusts the extension or retraction of the electric actuator 120 according to actual needs, thereby controlling the position of the horizontal partition 130. The control equipment is common existing technology, and will not be described in detail in this specification and accompanying drawings.

[0036] Its specific operating principle is as follows:

[0037] External water enters through the inlet pipe 1102, and fertilizer enters through the feeding port 1104. After the fertilizer and water are mixed in the mixing tank 110, they are discharged through the outlet pipe 1103. After the transport vehicle transports the main body of the integrated machine to the corresponding position, the outlet pipe 1103 is connected to the drip irrigation device to carry out drip irrigation operation.

[0038] By controlling the extension or retraction of the electric push rod 120, the electric push rod 120 drives the connected horizontal baffle 130 to move up and down within the mixing tank 110. Before transportation, the position of the horizontal baffle 130 can be adjusted according to the liquid level of the fertilizer solution in the mixing tank 110, thereby changing the size of the space containing the fertilizer solution in the mixing tank 110, so that the solution is closer to a full state during transportation, thereby reducing the free liquid surface area and lowering the sloshing energy density.

[0039] When the electric push rod 120 moves the horizontal partition 130, the space between the upper and lower parts of the mixing tank 110 changes, creating a pressure difference. At this time, the vent 140 comes into play, allowing airflow to pass through the airflow channel between the side wall of the floating sealing plug 150 and the inner wall of the lower floating cavity 1402, and then through the upper air guide hole 1401, balancing the pressure between the upper and lower parts of the mixing tank 110 and ensuring smooth movement of the horizontal partition 130. As the horizontal partition 130 continues to move downward, the liquid below increases, increasing the buoyancy of the float 1501 fixed to the lower end face of the floating sealing plug 150. The float 1501 drives the floating sealing plug 150 to overcome its own weight and the friction with the inner wall of the lower floating cavity 1402, moving upward along the direction of the axial guide rib 160 and the guide groove 170. As the floating sealing plug 150 moves upward, its upper end face gradually presses against the upper air guide hole 1401, achieving a seal and preventing the solution from overflowing from the vent 140 during transportation.

[0040] As the floating sealing plug 150 moves up and down due to buoyancy, two axial guide ribs 160 symmetrically arranged on its side wall tightly engage with two guide grooves 170 on the inner wall of the lower floating cavity 1402. The axial guide ribs 160 are embedded in the guide grooves 170 and slide up and down along the axial direction, providing precise guidance for the movement of the floating sealing plug 150, ensuring that it does not deviate or shake during its up and down movement, and always moves accurately towards the upper air vent 1401, achieving precise sealing.

[0041] Workers can directly observe the position of the horizontal baffle 130 inside the mixing tank 110 through the observation window 1101 on the tank body, as the electric push rod 120 moves the horizontal baffle 130 downward, and visually determine whether it has moved to the appropriate position. The rubber ring 1301 wrapped around the side wall of the horizontal baffle 130, with its good elasticity and flexibility, tightly conforms to the inner wall of the mixing tank 110 during the movement of the horizontal baffle 130, adapting to the shape of the inner wall to ensure smooth movement of the horizontal baffle 130, while filling the tiny gaps between the horizontal baffle 130 and the inner wall of the mixing tank 110 to prevent fertilizer solution leakage.

[0042] The above-mentioned settings, by adjusting the position of the horizontal baffle 130 to change the spatial distribution of the solution, effectively reduce the dynamic lateral force generated by solution sloshing, significantly improve the stability of the integrated water and fertilizer machine during transportation, ensure the smoothness of the equipment during movement, reduce the risk of accidents such as rollover, and ensure the safety of operators and the surrounding environment. The unique design of the vent 140 and sealing device can effectively balance the air pressure when the horizontal baffle 130 moves, and can automatically seal when needed to prevent solution overflow. The float 1501 enhances the sensitivity of the sealing device to liquid buoyancy, optimizing the timeliness of sealing; the symmetrical design of the axial guide rib 160 and guide groove 170 improves the accuracy and reliability of the seal, further ensuring the sealing of the solution during transportation.

[0043] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
