Description

Technical Field

[0001] This utility model relates to the agricultural field, specifically to a soil nitrogen fixation device. Background Technology

[0002] Using soil as a carrier to convert atmospheric nitrogen into NO3-N via a DBD plasma device and supplying it to crops can be considered a novel fertilization method with several advantages. First, the NO3-N generated in the soil by DBD plasma does not undergo ammonia nitrification as in conventional fertilization, thus improving fertilizer utilization and reducing over-reliance on nitrogen fertilizers. Second, the DBD plasma reaction conditions are mild, requiring no specific high-temperature and high-pressure conditions, and it does not consume fossil fuels such as coal and oil, nor does it produce greenhouse gases that impact the environment. Compared to industrial catalysts, using soil directly as a carrier for NO3-N deposition not only solves the problem of collecting ammonia generated by plasma, but soil itself is a natural material, making it more environmentally friendly. From a cost perspective, it eliminates the need for expensive hydrogen as a raw material, directly using atmospheric nitrogen and oxygen, which significantly reduces industrial production costs. Furthermore, only electricity is needed as an energy source to fully activate the reaction. Nitrogen fixation devices are crucial for research on the direct effects on different types of soil. However, existing soil nitrogen fixation devices do not provide direct soil-based research. Furthermore, experiments on different soil types need to be easy to operate and control in order to facilitate future application and promotion.

[0003] Therefore, to solve the above problems, a soil nitrogen fixation device is needed to conduct experimental tests on different soils under different conditions. Utility Model Content

The clamping claw mechanism clamps the nitrogen fixation mechanism for nitrogen fixation in the soil, and the cooling mechanism 2 is used for circulating cooling of the nitrogen fixation mechanism. The soil nitrogen fixation device of this technical solution can stably clamp the nitrogen fixation mechanism through the clamping claw mechanism to ensure clamping stability during the experiment, and can effectively cool the nitrogen fixation mechanism during use through the cooling mechanism. The overall structure is easy to adjust and convenient for experimental testing on different soils.

[0019] In this embodiment, the nitrogen fixation mechanism includes a condensation base 4 that is installed in conjunction with the clamping claw mechanism, a cathode disk 5 installed on the condensation base 4, a high-temperature resistant rubber ring 6 installed on the cathode disk 5, a quartz pressure plate 7 installed on the high-temperature resistant rubber ring 6, and an anode disk 8; the high-temperature resistant rubber ring 6 (which can be made of other non-conductive materials) is arranged between the cathode disk 5 and the quartz pressure plate 7 to form a space for placing soil. The condenser base 4 at the bottom of the nitrogen fixation mechanism is clamped by a clamping claw mechanism to ensure the stability of the overall structure. The cathode disk 5 is fixedly installed on the condenser base 4.

There are two of each type of assembly, which are arranged in a rectangular shape with intervals. The passive gripper assembly 33 can slide along the height direction of the support column 31. After the adjustable gripper assembly slides and adjusts in the vertical direction, it is positioned and locked. Due to the linkage rod 35, when adjusting the height, the adjustable gripper assembly adjusts the height and drives the passive gripper assembly 33 to adjust the height synchronously. After adjusting to the appropriate position, it is locked and positioned to ensure that the four gripper assemblies are at the same horizontal height.
