Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and more specifically to an integrated fertilization and irrigation device. Background Technology

[0002] Currently, agricultural operations require equipment that can perform both irrigation and fertilization functions. As a result, some integrated water and fertilizer equipment has emerged on the market. These typically include an irrigation mechanism and a fertilization mechanism connected to the irrigation mechanism. To integrate irrigation and fertilization, these devices require multiple pipes, resulting in complex structures, high costs, and susceptibility to damage. In addition, the irrigation mechanism needs to be equipped with a water flow control mechanism. When the water flow control mechanism adjusts the water flow of the irrigation mechanism, the water flow will impact other pipes. Furthermore, when the working environment is hot, the pipes are exposed to the sun, making them easily damaged by impacts or other factors. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides an integrated fertilization and irrigation device. This device uses a single power output unit to power both watering and fertilizing, avoiding the impact of water flow on other pipes caused by complex pipe structures including multiple bends. It also avoids the problem of excessive resistance changes during the switching between fertilization and watering, which can lead to significant resistance variations in the power unit. Furthermore, it avoids the problem of pipes being easily damaged by exposure to sunlight or impacts in high-temperature environments.

[0004] The purpose of this invention is to provide an integrated fertilization and irrigation device, comprising a housing, a fertilization device, and a flow control device, wherein the housing is provided with a first inlet, a second inlet, and an outlet.

[0009] More preferably, the connection between the fertilizer applicator and the housing is located at any position at the connection between the first housing and the second housing.

[0010] Furthermore, the first housing and the second housing are connected by a flange;

[0011] Preferably, the housing is cylindrical, and the control components of the flow control device are arranged radially inside the housing;

[0012] Furthermore, the first liquid inlet is located at one end of the housing, the liquid outlet is located at the other end of the housing, and the second liquid inlet is located on the side wall of the housing;

[0013] Preferably, the second liquid inlet is connected to a fourth tube, which is located outside the housing and communicates with the second liquid inlet; more preferably, the fourth tube is connected to a second flow regulating valve.

[0014] Furthermore, the control component is provided with a through hole, and the control component is rotatably mounted on the fertilizer application device through the through hole;

[0015] Preferably, the control element is a baffle or a block, and the baffle or block is provided with the through hole.

[0016] Furthermore, the flow control device also includes a rotating shaft, and preferably, an opening A is provided at the connection between the first housing and the second housing of the housing;

[0017] The rotating shaft extends from the outside of the housing into the housing through opening A. The rotating shaft is connected to the control component and is rotatably connected to the housing; this facilitates the disassembly and maintenance of the integrated fertilization and irrigation device.

[0018] Preferably, a control handle assembly for controlling the rotation of the shaft is connected to the shaft located outside the housing.

[0019] Furthermore, the control handle assembly includes a first handle, a limiting mechanism, and a second handle portion;

[0020] The limiting mechanism is connected to the housing. The limiting mechanism is provided with an opening B that aligns with the opening A. The limiting mechanism is also provided with grooves distributed circumferentially along the limiting mechanism.

[0021] The first handle is connected to the rotating shaft, and the limiting mechanism is located between the housing and the first handle;

[0022] The second handle portion includes a second handle and a limiting member. One end of the second handle is hinged to the first handle, and the other end is connected to the first handle through an elastic member. The limiting member is connected at an angle to the hinge point of the second handle and the first handle, and the shape of the limiting member matches the groove.

[0023] Preferably, the rotating shaft of the flow control device extends from the outside of the housing into the housing through openings B and A;

[0024] Preferably, the angle is 90-120°.

[0025] Furthermore, a switch valve is provided at the second liquid inlet.

[0026] Furthermore, the fertilization device includes a first tube, a second tube, and a third tube, with the second tube located between the first and third tubes. One end of the second tube is connected to the first tube, and the other end of the second tube is connected to the third tube.

[0027] The second tube body is provided with a second tube body inlet, and the second tube body is connected to the second inlet through the second tube body inlet;

[0028] Preferably, the first tube, the second tube, and the third tube are arranged along the axial direction of the shell.

[0029] Furthermore, the inner diameter of the first tube gradually decreases from the end furthest from the second tube to the end closest to the second tube;

[0030] The inner diameter of the third tube gradually increases from the end closer to the second tube to the end farther away from the second tube;

[0031] And / or,

[0032] The inner diameter of the end of the third tube that is furthest from the second tube is smaller than the inner diameter of the end of the first tube that is furthest from the second tube.

[0033] Preferably, the control component of the flow control device is rotatably mounted on the first pipe body.

[0034] Furthermore, a flow guide plate is connected to the outside of the third tube.

[0035] When the integrated fertilization and irrigation device is used for watering, the area between the inner diameter of the shell and the outer diameter of the first pipe is adjusted to the maximum by adjusting the flow control device. The water entering the shell passes through the area between the shell and the inner diameter of the shell and the outer diameter of the first pipe to reach the liquid outlet of the shell, and some water passes through the first pipe to reach the liquid outlet of the shell; thus realizing watering.

[0036] When the integrated fertilization and irrigation device fertilizes, the area between the inner diameter of the shell and the outer diameter of the first pipe is reduced by adjusting the flow control device. All or most of the water reaches the liquid outlet of the shell through the first pipe. When the water entering the first pipe reaches the third pipe, a negative pressure is formed in the second pipe, thereby drawing the undiluted liquid fertilizer into the fertilization device through the second pipe for primary mixing to obtain primary mixed liquid fertilizer. The primary mixed liquid fertilizer is then mixed a second time with the water in the shell that did not enter the first pipe to obtain finished liquid fertilizer, which flows out of the shell for use.

[0037] The advantages of this invention over the prior art are as follows: A fertilization device is installed inside the housing, arranged axially along the housing. The fertilization device includes a first tube, a second tube, and a third tube. After water enters the housing, some or all of the water enters the first tube. When water enters the third tube, a negative pressure is created in the second tube, drawing undiluted liquid fertilizer directly or through a fourth tube via a second inlet into the second tube. This achieves a primary dilution of the undiluted liquid fertilizer by mixing it with water in the third tube, resulting in a preliminary mixed liquid fertilizer. Furthermore, it avoids air blockage caused by the undiluted liquid fertilizer entering the fertilization device, which would prevent subsequent water from being applied.

[0038] Furthermore, the shell is equipped with a flow control device, which includes a control component located within the shell. This allows for the regulation and control of the concentration and flow rate of the finished liquid fertilizer, and the adjustment can be made at any time during movement without being affected by the environment. Simultaneously, since the primary mixed liquid fertilizer, after initial dilution, is dispersed and mixed axially within the shell along with the water passing between the inner diameter of the shell and the outer diameter of the first pipe, the primary liquid fertilizer and water are mixed. This avoids the air resistance problem caused by the primary liquid fertilizer and water not mixing axially, thus avoiding the problem of intermittent and uneven liquid fertilizer concentration when finally flowing out of the integrated fertilization and irrigation device. As a result, after adjusting the concentration, the liquid fertilizer achieves the same and stable fertilizer concentration in different cultivated land locations.

[0039] Furthermore, by placing the fertilization device inside the casing and connecting the fertilization device to the casing, the problem of water flow impacting other pipes caused by the complex pipe structure including multiple bends is avoided. At the same time, the problem of excessive resistance change causing the power device to bear excessive resistance change when switching between fertilization and watering states is also avoided.

[0040] The inner diameter of the first tube gradually decreases from the end furthest from the second tube to the end closest to the second tube;

[0041] The inner diameter of the third tube gradually increases from the end closer to the second tube to the end farther away from the second tube;

[0042] The system increases the flow rate of water after it enters the first pipe and reduces the air pressure in the second pipe, thereby providing the power for the undiluted liquid fertilizer to enter the second pipe.

[0043] The concentration and flow rate of the primary mixed liquid fertilizer are adjusted by the second flow regulating valve connected to the fourth pipe, thereby enabling a wider range of adjustment of the flow rate and concentration of the finished liquid fertilizer.

[0044] This allows the integrated water and fertilizer system to use a single power output device to provide power for both watering and fertilizing. The fertilizing device is located inside the casing and connected to it, avoiding the problem of water flow impacting other pipes due to complex pipe structures including multiple bends. It also avoids the problem of excessive resistance changes when switching between fertilizing and watering modes, which would cause excessive resistance changes to the power device. Furthermore, it avoids the problem of pipes being exposed to sunlight in high-temperature working environments, which could easily lead to damage from impacts. Attached Figure Description
