Description

Technical Field

[0001] This utility model relates to the field of soil trough test benches, and in particular to a soil trough test bench with adjustable soil moisture content. Background Technology

[0002] In agricultural machinery experiments, adjusting soil moisture content ensures consistency in soil condition, thereby improving the accuracy and repeatability of experimental data. Conventional soil moisture content adjustment in soil trough experimental platforms involves increasing or decreasing moisture content. Increasing soil moisture content is achieved by slowly adding water using a general sprayer or drip irrigation system; decreasing it is achieved through natural drying. Natural drying involves spreading the soil evenly and ventilating it to increase surface aeration. Currently, there are no patents or literature documenting specific methods for adjusting soil moisture content. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a soil trough experimental platform with adjustable soil moisture content.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A soil trough experimental platform with adjustable soil moisture content includes a soil trough body and an adjustment mechanism.

[0008] The adjustment mechanism is provided in multiple sets and installed at the bottom of the inner wall of the soil trough. The adjustment mechanism includes a vortex air pump, a main pipeline, a branch pipeline, an exhaust pipeline, and a plug.

[0009] The outlet of the vortex air pump is connected to the main pipeline through a first flexible hose;

[0010] The two ends of the main pipeline are connected to the branch pipeline via a second flexible hose;

[0012] The exhaust pipe is fitted with a plug at the end away from the right-angle bend, and the exhaust pipe has multiple exhaust holes on its body.

[0013] Preferably, the bottom of the inner wall of the soil trough is equipped with multiple pipe protective covers, each corresponding to a one-to-one exhaust pipe, and the exhaust pipe is also provided with a through hole corresponding to the exhaust hole.

[0014] Preferably, a fan filter is installed at the air inlet of the vortex air pump.

[0015] Preferably, the end of the exhaust pipe with the plug extends out of the trough.

[0016] Preferably, the soil trough contains, from top to bottom, a tillage layer, a plow layer, a sand layer, and a gravel layer.

[0017] Preferably, the pipe protective cover is fastened to the bottom of the soil trough body by self-tapping screws.

[0018] (III) Beneficial Effects

[0019] The beneficial effects of this utility model are as follows: By adopting the above technical solution, after the soil absorbs water and the moisture content increases to the point where the soil moisture content reaches saturation, the excess water will flow into the exhaust pipe. The plug can be manually unscrewed to overflow and discharge the excess water, or the vortex air pump can be turned on to blow out the excess water. When it is necessary to reduce the moisture content, the vortex air pump blows out high-pressure warm air. The airflow can enter the soil through the distributed pipes and pass through the gaps between the various soil layers. The airflow carries away the soil moisture and reduces the soil moisture content. Attached Figure Description

[0033] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Please refer to Figures 1 to 3 This utility model provides a soil trough experimental platform with adjustable soil moisture content, including a soil trough body 1 and an adjustment mechanism 2;

[0035] The regulating mechanism 2 is provided in multiple sets and installed at the bottom of the inner wall of the soil trough 1. The regulating mechanism 2 includes a vortex air pump 21, a main pipeline 22, a branch pipeline 23, an exhaust pipeline 24, and a plug 25.

[0036] The outlet of the vortex air pump 21 is connected to the main pipeline 22 through the first flexible hose;

[0037] Both ends of the main pipeline 22 are connected to the branch pipeline 23 via a second flexible hose;

[0038] Both ends of the branch pipe 23 are connected to the exhaust pipe 24 via right-angle elbows;

[0039] A plug 25 is installed at the end of the exhaust pipe 24 away from the right-angle bend, and multiple exhaust holes are provided on the pipe body;

[0040] When in use, once the soil absorbs water and its moisture content reaches saturation, excess water will flow into the exhaust pipe 24. The plug 25 can be manually unscrewed to overflow and discharge the excess water, or the vortex air pump 21 can be turned on to blow out the excess water. When it is necessary to reduce the moisture content, the vortex air pump 21 blows out a high-pressure, warm airflow. The airflow can enter the soil through the distributed pipes and pass through the gaps between the soil layers to remove soil moisture and reduce the soil moisture content.

[0041] It should be noted that an electric heating wire can be installed at the air inlet of the vortex air pump 21 to increase the heat of the exhaust gas from the vortex air pump 21.

[0042] The installation of the main pipeline 22, branch pipeline 23 and exhaust pipeline 24 ensures that the air is evenly distributed when it finally reaches the exhaust pipeline. The airflow then passes through the soil stratification filter layer from bottom to top. Heat and airflow from bottom to top accelerate the evaporation and dispersion of water vapor on the soil surface, thereby reducing the soil moisture content.

[0043] In this embodiment, multiple pipe protective covers 3 are installed on the bottom of the inner wall of the soil trough 1. The pipe protective covers 3 correspond one-to-one with the exhaust pipes 24, and the exhaust pipes 24 are also provided with through holes corresponding to the exhaust holes.

[0044] In this embodiment, a fan filter 26 is installed at the air inlet of the vortex air pump 21.

[0045] In this embodiment, the end of the exhaust pipe 24 with the plug 25 extends out of the soil trough 1.

[0046] In this embodiment, the soil trough 1 is provided with a tillage layer 4, a plow layer 5, a sand layer 6, and a gravel layer 7 from top to bottom.

[0047] In this embodiment, the pipe protective cover 3 is fastened to the bottom of the soil trough 1 by self-tapping screws.

[0048] The working principle of this utility model is as follows:

[0049] Once the soil absorbs water and its moisture content reaches saturation, excess water will flow into the exhaust pipe 24. The plug 25 can be manually unscrewed to overflow and discharge the excess water, or the vortex air pump 21 can be turned on to blow out the excess water. When it is necessary to reduce the moisture content, the vortex air pump 21 blows out a high-pressure, warm airflow. The airflow can enter the soil through the distributed pipes and pass through the gaps between the soil layers to carry away the soil moisture and reduce the soil moisture content.

[0050] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
