Description

Technical Field

[0001] This utility model relates to the field of measuring trench technology, specifically a measuring trench for soil erosion on sloping farmland. Background Technology

[0002] Soil erosion is one of the most significant ecological and environmental problems facing the world today, especially in sloping farmland, where its harm is particularly pronounced. Due to the steep slope of the terrain, sloping farmland is easily eroded by natural factors such as rainfall, wind, and human activities, leading to decreased soil fertility and reduced productivity. It also triggers a series of chain reactions such as siltation and river pollution, posing a serious threat to the ecological environment and agricultural production.

[0003] In the research and prevention of soil erosion, the portability and flexibility of experimental devices are crucial. Traditional soil erosion experimental devices are usually large in size and have a fixed structure, making them difficult to adapt to the needs of different experimental sites and inconvenient to move and reuse in different regions. In addition, these devices occupy a lot of space when not in use, and are difficult to store and store, increasing the management and maintenance costs of experimental equipment.

[0004] To improve the portability and flexibility of experimental devices while reducing storage and transportation costs, researchers have been exploring more optimized design solutions. However, most existing devices have failed to effectively address these issues. For example, while some devices can simulate the impact of natural factors such as rainfall or wind on soil erosion, their complex structures prevent them from being folded or collapsed, resulting in large sizes that are difficult to move and store. Other devices, although adjustable to some extent, still suffer from large space requirements and inconvenient operation when stored.

[0005] Therefore, a soil erosion measurement trench for sloping farmland is needed to improve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a soil and water loss measurement trench for sloping farmland to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a soil and water loss measuring trench for sloping farmland, comprising a fixed trench, a sliding trench slidably provided inside the fixed trench, an air pump fixedly provided on one side of the sliding trench, the air pump being connected to an air jet pipe via a pipeline, a plurality of spray pipes fixedly provided inside the sliding trench, an adobe tray fixedly provided at the bottom of the sliding trench, a guide trench provided on the surface of the fixed trench, a filter trench connected to one side of the guide trench, a telescopic support rod slidably provided below the fixed trench, a pulling groove provided at the lower end of the sliding trench, the end of the telescopic support rod being L-shaped and slidably provided inside the pulling groove.

[0008] As a preferred embodiment of this utility model, the jet pipe is inclined to correspond to the adobe tray, and the spray pipe is vertically and vertically aligned with the adobe tray.

[0009] As a preferred embodiment of this utility model, one side of the lower surface of the fixing groove is hinged to the support rod of the water tank, and the other side of the lower surface of the fixing groove is fitted and connected to the support rod of the water tank.

[0010] As a preferred embodiment of this utility model, the water tank surface is hinged to be equipped with a hydraulic cylinder, and the other end of the hydraulic cylinder is hinged to the lower surface of the fixed groove.

[0011] As a preferred embodiment of this utility model, a hydraulic pump is fixedly installed at the upper end of the water tank, and the hydraulic pump is connected to the hydraulic cylinder for transmission.

[0012] As a preferred embodiment of this utility model, a water pump is fixedly installed at the upper end of the water tank, and the water pump is connected to the spray pipe through a water pipe.

[0013] As a preferred embodiment of this utility model, a recycling box is provided on the lower surface of the fixed groove corresponding to the filter groove, and several universal wheels are fixedly provided at the lower end of the water tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This device integrates a spray pipe and an air pump, which can simultaneously simulate the effects of rainfall and wind on soil erosion. By controlling the spray intensity, time and wind force, it can accurately simulate the soil erosion process under different natural conditions, providing a powerful tool for studying the mechanism of soil erosion under the combined effects of multiple factors.

[0016] 2. Through the cooperation of hydraulic cylinders and hydraulic pumps, the fixed groove of this device can be tilted at different angles to simulate the conditions of sloping farmland with different slopes. This design can more realistically reflect the soil and water loss of actual sloping farmland and provide more targeted experimental data for the formulation of soil and water conservation measures.

[0017] 3. The sliding groove of this device can slide flexibly within the fixed groove, and its position can be adjusted according to the size of the adobe sample or experimental requirements, which greatly improves the flexibility and adaptability of the experiment. At the same time, after the sliding groove is retracted into the fixed groove, the size of the device is greatly reduced, making it easy to store and save space. The device is equipped with casters at the bottom, which can be easily moved to different experimental sites without complicated disassembly and assembly processes, greatly improving experimental efficiency. It is especially suitable for situations where experiments need to be conducted in multiple locations. Attached Figure Description

[0031] The sliding groove 4 slides inside the fixed groove 6. The position of the sliding groove 4 can be adjusted as needed to accommodate adobe samples of different sizes or to perform different experimental operations.

[0032] Air pump 1 is connected to jet pipe 2 through a pipe. Jet pipe 2 is set at an angle to correspond to adobe tray 5. When air pump 1 is started, it will deliver gas to jet pipe 2.

[0035] A filter tank 14 is connected to one side of the flow channel 13. After the sediment and water flow enter the filter tank 14, the sediment will be intercepted by the filter device in the filter tank 14, such as a filter screen or filter plate, while the water will continue to flow.

[0037] As an example of this utility model, one side of the lower surface of the fixing groove 6 is hinged to the support rod of the water tank 9, and the other side of the lower surface of the fixing groove 6 is fitted and connected to the support rod of the water tank 9.

[0038] As an example of this utility model, a hydraulic cylinder 12 is hinged to the surface of the water tank 9.

The eroded mud and water flow will flow into the guide channel 13 of the fixed channel 6 along the bottom of the sliding channel 4. A filter channel 14 is connected to one side of the guide channel 13. After the mud and water flow enter the filter channel 14, the mud will be intercepted by the filter device in the filter channel 14, such as a filter screen or filter plate, while the water flow will continue to flow. By observing and measuring the amount of mud in the filter channel 14, the degree of soil erosion can be quantitatively analyzed.

[0046] A telescopic support rod 15 is slidably provided on the lower side of the fixed groove 6, and a pull groove 16 is provided at the lower end of the sliding groove 4. The end of the telescopic support rod 15 is L-shaped and is slidably provided inside the pull groove 16.

[0047] One side of the lower surface of the fixed groove 6 is hinged to the support rod of the water tank 9, and the other side is fitted to the support rod of the water tank 9. This connection method allows the fixed groove 6 to be adjusted at a certain angle relative to the water tank 9, thereby simulating the conditions of sloping farmland with different slopes.
