Description

Technical Field

[0001] This utility model belongs to the field of plant quarantine, and in particular relates to a plant quarantine device. Background Technology

[0002] Phytosanitary fumigation is an important quarantine treatment technique primarily used to prevent the spread of harmful organisms through international trade or transportation. This technique utilizes chemical fumigants to release toxic gases in a confined environment, killing or inhibiting pests, pathogens, and other harmful organisms carried by plants, timber, packaging materials, etc. Phytosanitary fumigation is widely used in the quarantine of imported and exported agricultural products, wooden packaging, and stored goods, and is an important means of ensuring agricultural production safety and ecological balance.

[0003] Comparing with Chinese Patent CN221044121U, a plant quarantine device for advanced agronomists is disclosed, comprising: a fumigation box; a lifting unit fixedly installed inside the fumigation box, capable of adjusting the size of the internal space; an air circulation unit fixedly installed at the top of the fumigation box, capable of accelerating airflow; a fumigant storage box fixedly installed on one side of the upper surface of the fumigation box; an atomizing nozzle disposed inside the fumigation box; the lower end of the fumigant storage box being fixedly connected to the atomizing nozzle; and an inlet / outlet on one side of the fumigation box. The device allows for adjustment of the fumigation space inside the fumigation box to a suitable size for the target area by activating the lifting unit, and the air circulation unit accelerates the flow rate of the fumigant gas inside the fumigation box, ensuring full contact between the plants and the fumigant gas, thus improving the fumigation effect.

[0004] However, the aforementioned patent uses traditional static placement of quarantine plants for fumigation, which easily creates blind spots at the bottom of the quarantine plants, greatly reducing the uniformity and comprehensiveness of fumigation. Therefore, a new device needs to be designed. Utility Model Content

[0012] Furthermore: the translation component includes a translation frame for mounting and fixing the atomizing nozzle, a linear motor is mounted on the translation frame, and a linear guide rail is provided in the middle of the linear motor.

[0013] Furthermore: the air intake pipe passes through the top of the outer casing assembly, and the air delivery hose is connected to the atomizing nozzle and the air intake pipe clamp respectively.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. The rotational design of the inner box component (servo motor drives the mesh cylinder to rotate) is combined with the linear reciprocating motion of the spraying component (linear motor drives the atomizing nozzle) to achieve multi-directional coverage of the fumigant in three-dimensional space, avoiding the dead angle problem of traditional static fumigation;

[0016] 2. The flip-top mesh inner box, combined with a locking mechanism, enables quick loading and unloading of plants, improving operational efficiency; the cylindrical inner box structure matches the horizontal spraying path, maximizing the use of the box space and suitable for the treatment needs of plants of different sizes;

[0017] 3. The electric fan at the bottom of the outer box forces convection, accelerating the contact frequency between the fumigation gas and the plant surface, further ensuring the uniformity of pesticide penetration; the transparent window design allows real-time observation of the internal fumigation status, enabling you to monitor the process without opening the door, ensuring both airtightness and ease of operation.
