Description
Technical Field
The invention relates to the technical field of plant quarantine, in particular to a quarantine plant disease specimen collecting device and a using method thereof.
Background
Plant quarantine is a measure for preventing artificial transmission of dangerous plant diseases, insects, weeds and other harmful organisms by means of laws, administration and technology, ensuring the safety of agriculture and forestry and promoting the development of trade. It is a product of the long-term struggle between human beings and nature, and is also a system generally implemented by countries in the world. Therefore, plant quarantine is a special plant protection measure, relates to aspects such as legal regulations, international trade, administrative management, technical support, information management and the like, and is a comprehensive management system. Plant quarantine is a traditional plant protection measure, but is different from other disease and pest control measures. The plant protection work comprises five aspects of prevention or stopping, eradication, immunity, protection, treatment and the like. Plant quarantine is an important part of the plant protection field, and the content thereof relates to various aspects of prevention, prevention or eradication in plant protection, and is also one of the most effective, most economical and most advocated aspects, and sometimes even the only specific measure in a certain integrated pest control (IPM) plan.
The quarantine of plants adopts a legislative measure to prevent the plants and the products thereof from spreading harmful organisms in the circulation process. It is characterized in that the introduction, the planting and the expansion of all harmful organisms (especially those not existing in the area) are prevented from the macroscopic view. Because of its legal obligation, "regulatory control" and "administrative action control" are often used as synonyms in the international literature. In 2007, China publishes an entry plant quarantine pest entry, wherein 446 species (genus) exist, and 227 species (genus) exist in quarantine pests. The quarantine regulation is made according to the conditions of distribution regionality, possibility of expanding distribution into harmful areas, main transmission way, selectivity to host plants, adaptability to environment, control function of natural enemies of the origin, possibility of transmission along with other conditions, packaging materials, import from which countries or regions can be forbidden, and entry through which designated ports and import time can only be passed, and the like, and also has corresponding regulations by taking the biological characteristics and ecological characteristics of some pathogenic substances, pests, weeds and the like as theoretical basis.
Based on the above, in the plant quarantine process, the plant disease part needs to be collected firstly, then the samples are placed under a microscope for observation, the change of the internal tissues is observed, and the final quarantine item is confirmed by matching with other biological experiment data of the sampled samples, so that the aim of quarantine is fulfilled.
The sample sampling device in the existing plant quarantine toolbox has a single structure, and can only collect one sample at a time, so that the economic cost is increased, and the sampling efficiency is very low. And often more difficult and troublesome when taking a sample to the higher plant of height when taking a sample, simultaneously at the sample in-process, need carry out cutting work to the plant sample, need the manual work to carry out fixed work to the plant simultaneously to make things convenient for the collection of plant sample, the operation is very loaded down with trivial details, and harmful disease worm etc. on the plant contacts with the human body very easily, causes sample pollution or pest to escape easily.

The invention also provides a use method of the quarantine plant disease specimen collecting device, and the quarantine plant disease specimen collecting device comprises the following steps:
s1, firstly, placing the device on one side of a plant, sliding the rack 9 upwards, driving the rotating rod 12 to rotate by the rotation of the rack 9 through the gear 11, driving the first rotating wheel 35 to rotate by the rotating rod 12 through the rotating wheel rope 34, driving the second rotating wheel 36 to rotate under the action of the deflector rod 32, and then driving the sliding cover 20 to open through the sliding cover rope 13, thereby opening the corresponding sampling box 19;
s2: with the continuous rotation of the rack 9, after the rack 9 is contacted with the spring switch, the spring switch is contacted with the second rotating wheel 36 so as to limit the continuous rotation of the second rotating wheel 36, at the moment, the sampling box 19 is completely opened, meanwhile, the opening part of the box body 1 is opened, and the plant part to be sampled is inserted into the box body 1;
s3: the rack 9 slides downwards, the rack 9 drives the rotating rod 12 to rotate through the gear 11, the first rotating wheel 35 is reset under the action of the volute spiral spring, at the moment, the deflector rod 32 slides in the limiting groove 10 under the action of the third spring 24, the rotating rod 12 is used for clamping plant branches, then the cutter 18 is driven to move through the driving mechanism, the plant branches are cut off, and cut-off parts fall into the sampling box 19;
s4: after sampling is finished, the rack 9 slides upwards, the rack 9 rotates through the gear 11 to drive the rotating rod 12 to rotate, at the moment, the rotating rod 12 does not clamp plant branches any more, then the plants are taken out, in the process, under the action of the torsion spring 321, the deflector rod 32 rotates around the movable block 322, and the first rotating wheel 35 rotates relative to the second rotating wheel 36;
s5: after the rack 9 contacts with the spring switch, the spring switch no longer restricts the rotation of the second wheel 36, then slides the rack 9 downwards to the initial position, and simultaneously under the action of the second spring 15, the sliding cover 20 and the rotating rod 12 return to the initial position, thereby completing the collection work of the plant specimen.
The spring switch working method comprises the following steps: in step S2, after the rack 9 contacts the brake lever 38, the brake lever 38 is driven to move upward, and the limiting rod 40 slides in the sliding groove 41, and when the limiting rod 40 moves to the lower bending portion 411, the upper end of the brake lever 38 is in close contact with the second pulley 36, so as to limit the second pulley 36; in step S5, after the rack 9 contacts the brake lever 38, the brake lever 38 is driven to move upward while the stopper lever 40 slides in the sliding groove 41, and when the stopper lever 40 moves to the upper bending part 412, the upper end of the brake lever 38 no longer contacts the second pulley 36.
In step S1, the first L-shaped seat 7 is manually slid upward, and the first L-shaped seat 7 drives the rack 9 to move upward.
