Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, and in particular to a drainage weighing device. Background Technology

[0002] In agricultural production, to ensure normal crop growth and increase yield, it is necessary to measure parameters such as drainage volume, EC value, pH value, and liquid temperature while ensuring a normal water supply. Although manual measurement is feasible, it is time-consuming, inefficient, and lacks data accuracy. Currently, the market uses spoons to count and collect drainage volume to monitor pH and EC values ​​to determine whether the concentration of potted plant drip irrigation is accurate. However, existing spoon counting has many drawbacks: first, it relies on magnetic force to control the tilting, and improper magnetic force can affect the number of tilts, resulting in inaccurate values; second, it requires manual calibration, which is inefficient and the collection of inflow and outflow values ​​is inaccurate; third, the spoon moves through a bearing, and liquid crystallization on the bearing surface can cause the spoon to jam, preventing timely drainage and affecting efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a drainage weighing device to address the shortcomings of existing devices that use spoons to count and determine the concentration of drip irrigation in potted plants in terms of measurement accuracy, as well as their low operating efficiency, which makes it difficult to meet the needs of actual agricultural production.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments 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 are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0019] Example 1:

[0020] As shown in the figure, a drainage and weighing device monitors the remaining water volume and fertilizer concentration after irrigation. It includes a collection tank 1, a drainage pipe 2, and a weighing sensor 3. The collection tank 1 has a built-in cavity for collecting drainage from the potted plant. One end of the drainage pipe 2 is connected to the collection tank 1, and the other end is connected to the bottom of the potted plant. The weighing sensor 3 is fixed to the bottom of the collection tank 1 to continuously measure the total weight change of the collection tank 1 and the collected liquid. It can accurately and in real time quantify the actual drainage volume after each irrigation of the potted plant, that is, the remaining water and fertilizer that have not been absorbed by the plant, thereby accurately assessing the irrigation efficiency and the plant's water and fertilizer requirements.

[0021] The top of the liquid collection tank 1 is provided with a collection port 11 that connects to the receiving cavity.

[0022] The drainage pipe 2 includes a first pipe section 21, a second pipe section 22 and a third pipe section 23. The axis of the first pipe section 21 extends vertically. One end of the first pipe section 21 is used to connect to the bottom of the potted plant, and the other end is connected to the second pipe section 22.

[0023] The axis of the second pipe section 22 extends horizontally, and at least a first detection sensor 41 and a second detection sensor 42 are fixed on the second pipe section 22 for detecting the liquid in the drain pipe 2. Preferably, the first detection sensor 41 is an EC detection sensor and the second sensor is a pH detection sensor. The horizontal arrangement of the second pipe section 22 ensures that the liquid fills the pipe section and flows smoothly when flowing through the sensors, without bubbles or uneven liquid coverage. This provides a stable and consistent detection environment for the sensors, thereby ensuring the accuracy and repeatability of the EC and pH readings.

[0024] The axis of the third pipe section 23 is inclined to the vertical direction, that is, the third pipe section 23 is inclined toward the collection port 11 of the collection tank 1, so that the drained liquid can drip into the collection tank 1 from the collection port 11, avoiding liquid splashing outside the collection tank 1, ensuring that all drained liquid is effectively collected and weighed, and guaranteeing the integrity of the drained liquid volume data. Preferably, the collection port 11 is located near the middle of the top of the collection tank 1 to prevent liquid from flowing along the tank wall or dripping at an irregular position, avoiding uncontrollable mixing of residual liquid from different drains on the tank body, and reducing the potential interference of cross-contamination to subsequent weighing and testing.

[0025] The liquid discharge weighing device includes a rigid and stable support 5, which is a rigid and stable frame structure. In this embodiment, the weighing sensor 3 adopts a cantilever beam structure. One end of the weighing sensor 3 is rigidly connected to the support 5 by bolts or a special clamp, and the other end extends horizontally as the force-bearing end. The liquid collection tank 1 is fixedly connected to or suspended from the force-bearing end of the weighing sensor 3 through its top, so that the weight of the liquid collection tank 1 and the liquid collected inside it acts completely and directly on the sensitive beam of the weighing sensor 3.

[0026] The drain weighing device also includes a drain actuator 6, which is connected to a first guide pipe 61 and a second guide pipe 62. One end of the first guide pipe 61 is connected to the input end of the drain actuator 6, and the other end is connected to the receiving cavity of the collection tank 1. Preferably, the input end of the drain actuator 6 is connected to the bottom of the receiving cavity of the collection tank 1 through the first guide pipe 61, ensuring that the liquid in the collection tank 1 can be effectively extracted under negative pressure. The output end of the drain actuator 6 is connected to an external drainage system, a wastewater recycling tank, or a specific waste liquid collection container through the second guide pipe 62. Preferably, the first guide pipe 61 and the second guide pipe 62 are made of chemically stable, flexible, and durable food-grade silicone tubing or PVC hose to ensure that they do not react or age during long-term contact with water and fertilizer, and to facilitate installation. The diameters of the first guide pipe 61 and the second guide pipe 62 are matched with the throughput capacity of the drain actuator 6 to achieve efficient emptying.

[0027] In this embodiment, the drain actuator 6 is a drain motor. In other embodiments, the drain actuator 6 may be a solenoid valve or a submersible pump.

[0028] In this embodiment, the top of the collection tank 1 is provided with multiple extension holes, each of which can be fitted with a quick-release component. The quick-release component is fixed to the bracket 5, and can be quickly fastened and fixed to the collection tank 1 and the bracket 5 by pushing it in. Preferably, the quick-release component is a T-nut, which includes a head and a screw connected to the head. The shape of each extension hole on the top of the collection tank 1 matches the head of the T-nut, allowing the head to be inserted laterally and limited. The bracket 5 is provided with a mounting part for fixing the screw of the T-nut. During installation, the collection tank 1 is pushed in laterally so that the head of the T-nut is inserted into the corresponding extension hole, and the quick fastening and fixing between the collection tank 1 and the bracket 5 is achieved by rotation or locking mechanism. More preferably, the extension holes are set in four groups, correspondingly distributed in symmetrical laterally on the top of the collection tank 1, and each group of holes can accommodate one quick-release component.

[0029] Example 2:

[0030] The difference from Embodiment 1 is that the draining weighing device also includes a control unit, which integrates a motherboard, an EC signal processing board, a pH signal processing board, and a wireless communication module. As the core control structure, the control unit is responsible for coordinating the acquisition, processing, and analysis of all sensor data, and can remotely transmit real-time monitoring data and equipment status to the cloud or a local dedicated control platform via a built-in antenna.

[0031] When the drainage liquid from the potted plant flows through the second pipe section 22, the first detection sensor 41 and the second detection sensor 42 continuously detect the conductivity and pH of the liquid and feed the electrical signal back to the control unit. The control unit compares the EC value and pH value of the drainage liquid with the original irrigation solution through an algorithm, thereby generating a fertilizer ratio adjustment command.

[0032] The cantilever beam type weighing sensor 3 supports the liquid collection tank 1. The liquid is precisely dripped into the liquid collection tank 1 through the end of the pipe. The weighing sensor 3 monitors the weight increment of the liquid collection tank 1 in real time. By continuously calculating the weight change, the instantaneous liquid discharge rate and the cumulative liquid discharge volume are accurately obtained.

[0033] When the control unit determines that the liquid volume in the collection tank 1 has reached the preset threshold based on the weighing data, it will start the drain actuator 6 to automatically drain part or all of the liquid in the collection tank 1 to the external wastewater system through the first guide pipe 61 and the second guide pipe 62, so as to ensure that the device can continuously carry out a new round of monitoring cycle.

They should not be construed as limiting the scope of protection of this utility model.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
