It is necessary to open a vertical hollow pipe at the axis of the vertical deep tillage tool and the rotating shafts connected thereto, and the spraying hole is directly connected to the bottom of the vertical deep tillage tool. The fertilizer is sprayed into the soil that is being deep tilled as the vertical deep tillage tool rotates, thereby realizing the functions of deep tillage and deep fertilization at the same time.

However, several groups of parameter matching experiments are directly carried out on the deep tiller. The experimental operation is cumbersome, the value range of each parameter is limited, and the fertilization effect is inconvenient to observe.

In the above-mentioned vertical deep loosening tool fertilizer pipeline pressure experimental device, the fertilizer pipeline 2 is inserted into the soil layer of the transparent soil pressing box 3, which is equivalent to the vertical deep loosening tool being inserted into the soil layer to be deep loosened. The pumping pressure of the pumping mechanism 1 is adjusted to adjust the flow rate and pressure of the liquid fertilizer in the fertilizer pipeline 2. The hardness of the soil layer in the transparent soil pressing box 3 is adjusted to adjust the soil hardness conditions. The fertilizer pipeline 2 introduces the fertilizer liquid into the soil layer to simulate the fertilization process of the vertical deep loosening tool. The infiltration of the fertilizer liquid into the soil layer is observed through the transparent soil pressing box 3, thereby realizing the corresponding pumping pressure test required for the fertilizer pipeline under the soil hardness conditions, and obtaining the corresponding pumping pressure required for the fertilizer pipeline under the soil hardness conditions, providing experimental data for the fertilizer pipeline pressure adjustment of the vertical deep loosening tool. The transparent soil pressing box 3 adjusts the soil layer hardness to form multiple levels of soil hardness. As a soil model under different environments, the experimental scope is expanded and the practicality is improved.

The pumping mechanism 1 includes a pumping fertilizer box 11 storing liquid fertilizer and equipped with a submersible water pump, a pressure regulating box 12 installed on the pumping fertilizer box 11 for regulating the pumping pressure of the submersible water pump, and an external power supply 13 for supplying power to the submersible water pump and the pressure regulating box. The submersible water pump is arranged in the pumping fertilizer box 11, pumping the fertilizer liquid into the fertilization pipeline 2, and the pressure regulating box 12 regulates the pumping pressure of the submersible water pump and controls the opening and closing of the submersible water pump.

The fertilization pipe 2 includes a pumping butt pipe 21 butted and connected to the outlet of the submersible water pump extending into the pumping fertilizer box 11, a five-hole diverter 22 butted and connected to the pumping butt pipe 21, a branch hose 23 butted and connected to the branch end of the five-hole diverter 22, and a jetting hard pipe 24 butted and connected to the branch hose 23 through a pipe joint, and the jetting hard pipe 24 is inserted into the soil layer of the transparent soil pressing box 3. The five-hole diverter 22 divides the liquid in the pumping butt pipe 21 into five tributaries, and the five tributaries are respectively diverted to the soil layer through the branch hose 23 and the jetting hard pipe 24. The diversion path of the fertilization pipe 2 simulates the fertilization diversion path in the vertical deep loosening tool to ensure the reliability and effectiveness of the test. At the same time, the setting of the branch hose 23 facilitates the insertion of the jetting hard pipe 24 into the soil layer. The depth of the jetting hard pipe 24 inserted into the soil layer is between 25 and 30 cm, which is consistent with the deep loosening depth of the vertical deep loosening tool, ensuring the reliability of the test.

Wherein, the pumping butt joint 21 is equipped with a pressure gauge 25 and a flow meter 26, and the tributary ends of the five-hole diverter 22 are equipped with a tributary switch 27 and a flow meter 26.

The five-hole diverter 22 is supported on the bracket 4 and is arranged horizontally. The branch hose 23 is connected to each branch end to form a side-by-side arrangement. When the injection hard pipe 24 is not inserted into the soil layer, the sum of the lengths of the branch hose 23 and the injection hard pipe 24 is greater than the distance between the branch end of the five-hole diverter 22 and the surface of the soil layer. The injection hard pipe 24 is inserted into the soil layer by pushing and pressing the buckling handle 242. The insertion depth is 25 to 30 cm. After being inserted into the position, the branch hose 23 is basically straightened. The convex horizontal perforated pipe 241 is arranged horizontally to avoid being blocked when the injection hard pipe 24 is inserted into the soil layer. After insertion, the liquid fertilizer is introduced into the soil layer through the convex horizontal perforated pipe 241, which is consistent with the fertilizer outlet direction of the vertical deep loosening tool, further ensuring the reliability of the test.
