Description

Technical Field

[0001] This utility model belongs to the field of irrigation equipment technology, specifically relating to an irrigation device for tomato cultivation. Background Technology

[0002] This invention relates to the field of agricultural irrigation technology, and in particular to an irrigation device for greenhouse tomato cultivation. In existing technologies, greenhouse tomato cultivation mostly uses surface irrigation or ordinary drip irrigation systems, where most of the irrigation water seeps below the crop root zone, forming deep seepage that is difficult to utilize, resulting in low water resource utilization efficiency. This problem not only wastes water resources but also leads to nutrient loss. Therefore, there is a need for a device that can effectively reduce seepage loss and improve irrigation water utilization efficiency to overcome the shortcomings of existing technologies. Utility Model Content

[0003] In order to overcome the problems existing in the background art, the present invention provides an irrigation device for tomato planting.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an irrigation device for tomato cultivation, comprising: multiple parallel water collection troughs located on the ground of a greenhouse; planting troughs, the same number as the water collection troughs and correspondingly housed within the water collection troughs, with a gap between the outer wall of the planting trough and the inner wall of the water collection trough; a collection ditch located at the same end of all the water collection troughs and connected to all the water collection troughs; a drip irrigation pipeline located inside the greenhouse, with its outlet end corresponding to each of the planting troughs; and a water supply system connected to the input end of the drip irrigation pipeline; the bottom and side walls of the water collection troughs and the collection ditch are covered with an impermeable layer.

[0005] Preferably, the top edge of the planting trough extends outward to form a supporting flange, and the planting trough overlaps the top of both sides of the water collection trough through the supporting flange; a number of drainage holes are provided at the bottom and lower part of the side wall of the planting trough.

[0006] Preferably, the bottom of the collecting ditch is provided with a drain outlet, and a control valve is provided at the drain outlet.

[0007] Preferably, the drip irrigation pipeline includes a main pipeline and a plurality of branch pipelines connected in parallel to the main pipeline. Each branch pipeline corresponds to one of the planting troughs, and each branch pipeline is provided with at least one drip irrigation nozzle.

[0008] Preferably, the water supply system includes a water pump connected to the main pipeline, and the water inlet of the water pump is connected to both an external water source and the control valve via a pipeline.

[0009] Preferably, the pipeline is a tee pipe, the first branch of the tee pipe is connected to the control valve, and the second branch of the tee pipe is equipped with a valve and connected to the external water source.

[0010] Preferably, the cross-section of the planting trough is an inverted trapezoid, and the drainage hole is a round hole.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention constructs a seepage and water recycling network by setting a water collection trough and a convergence channel below the planting trough. Ineffective water that seeps below the root zone is systematically collected and recycled through connection with the water supply system, fundamentally reducing irrigation water waste. Furthermore, the drainage holes at the bottom and side walls of the planting trough, combined with the gap at the bottom, ensure good aeration and drainage of the root zone substrate, effectively avoiding root flooding, oxygen deficiency, and root rot that are common with traditional irrigation methods.

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below to facilitate understanding by those skilled in the art.

[0015] Please see Figures 1 to 3 This embodiment provides an irrigation device for tomato cultivation, comprising: Multiple parallel water collection troughs 1 are provided on the ground of the greenhouse. The cross-section of the water collection trough 1 is trapezoidal to facilitate water flow. The bottom and side walls are provided with an impermeable layer to prevent water from seeping down.

[0016] Planting troughs 2, the same number as the water collection troughs 1, are housed within the water collection troughs 1, with a gap between the outer wall of the planting trough 2 and the inner wall of the water collection trough 1. The top edge of the planting trough 2 extends outward to form a supporting flange 3, and the planting trough 2 overlaps the tops of both sides of the water collection trough 1 via the supporting flange 3. Several drainage holes 4 are provided at the bottom and lower part of the side walls of the planting trough 2. The cross-section of the planting trough 2 is an inverted trapezoid, and the drainage holes 4 are circular. The drainage holes 4 and the bottom gap cooperate with each other to ensure good aeration and drainage of the root zone substrate, effectively avoiding root flooding, oxygen deficiency, and root rot that are easily caused by traditional irrigation methods. The planting troughs are filled with soil substrate.

[0017] A collection ditch 5 is located at the same end of all the water collection troughs 1 and is connected to all the water collection troughs 1. Its bottom and side walls are provided with an impermeable layer. The depth of the collection ditch 5 exceeds that of the water collection troughs 1. Water collected in the water collection troughs 1 is collected and stored in the collection ditch 5. If necessary, water can also be poured into the collection ditch 5, and the water will flow back into the water collection troughs 1 to irrigate the tomato roots. A drain outlet 6 is located at the bottom of the collection ditch 5, and a control valve 7 is installed at the drain outlet 6. When the water level in the collection ditch 5 is too high, water is discharged through the control valve 7 to control the water level.

[0018] The drip irrigation pipeline is installed inside the greenhouse, with its outlet end corresponding to each of the planting troughs 2. The drip irrigation pipeline includes a main pipeline 8 and multiple branch pipelines 9 connected in parallel to the main pipeline 8. Each branch pipeline 9 corresponds to one of the planting troughs 2, and each branch pipeline 9 is provided with at least one drip irrigation nozzle 10. Adjacent drip irrigation nozzles 10 are spaced 25-50cm apart.

[0019] The water supply system includes a water pump 11 connected to the main pipeline 8. The inlet of the water pump 11 is connected to both an external water source and the control valve 7 via a pipeline. The pipeline is a T-junction 12. The first branch pipe 13 of the T-junction 12 is connected to the control valve 7, and the second branch pipe 14 of the T-junction 12 is equipped with a valve 15 and connected to the external water source. When there is water in the collecting ditch 5, the control valve 7 is opened to draw water from the collecting ditch 5 to supply water to the drip irrigation pipeline. When there is insufficient water in the collecting ditch 5, the valve 15 is opened to use the external water source to supply water to the drip irrigation pipeline.

[0020] When using the irrigation device for tomato cultivation of this utility model: 1. Normal drip irrigation operation The water supply system is activated, and pump 11 pumps water (initially from an external water source) into the drip irrigation pipeline. The water flows through the drip irrigation nozzles 10 on the branch pipeline 9, evenly irrigating the tomatoes in the planting trough 2 in the form of drip irrigation or micro-spraying. Excess irrigation water seeps out through the drainage holes 4 at the bottom and side walls of the planting trough 2.

[0021] 2. Seepage collection and circulation Water seeping from the planting trough 2 drips into the trapezoidal water collection trough 1 below. The water naturally flows into the collection ditch 5 at the end, where it is stored and the water resources are recycled.

[0022] 3. Water source switching When the water level in the collection ditch 5 is high, the control valve 7 at its bottom is opened, and the water pump 11 is started simultaneously. At this time, the system will prioritize drawing the circulating water collected in the collection ditch 5 for drip irrigation, forming a closed-loop water circulation mode. When the water level in the collection ditch 5 drops and the water source is insufficient, the control valve 7 is closed, and the valve 15 connecting to the external water source is opened. The system will seamlessly switch to the external water source to ensure the continuity of irrigation.

[0023] 4. Emergency drainage and water level management During the rainy season or when the water volume is too large, the excess water can be discharged out of the system by fully opening the control valve 7 at the bottom of the collection ditch 5 to prevent the water level from becoming too high.

[0024] 5. Reverse irrigation Under specific circumstances (such as when precision drip irrigation is not required for a short period of time), water can be directly injected into the collection ditch 5 via an external water pump 11. After the water level in the ditch rises, it will backflow into each water collection tank 1, providing a basic moist environment for the tomato roots through soaking.

[0025] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
