Description

Technical Field

[0001] This utility model relates to the field of forestry plant sampling technology, specifically to a forestry plant quarantine sample collection device. Background Technology

[0002] Plant quarantine is a measure implemented through legal, administrative, and technical means to prevent the human-induced spread of dangerous plant diseases, insects, weeds, and other harmful organisms, thereby ensuring agricultural and forestry safety and promoting trade development. Plant quarantine is a traditional plant protection measure and an important part of the field of plant protection. Its characteristic is the prevention, on a macro-level basis, of the introduction, establishment, and spread of all harmful organisms (especially those not found within the local area). Plant quarantine uses legislative means to prevent the spread of harmful organisms by plants and their products during circulation.

[0003] The process of sampling leaves for plant quarantine requires cutting the leaves into tissue samples of appropriate size before extraction and testing, which is time-consuming and labor-intensive. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a forestry plant quarantine sample collection device that can quickly slice plant leaves, saving time and effort.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a forestry plant quarantine sample collection device, including a handle, a fixed housing on one side of the handle, a movable groove on one side of the fixed housing, a slider slidably connected in the movable groove, a detachable sampling blade tube fixedly connected to one side of the slider, the lower end of the sampling blade tube being a sharpened end, a support base fixedly connected to the lower end of the fixed housing, and a support boss cooperating with the sampling blade tube fixedly connected to the upper end of the support base; an air tube is slidably inserted into the end of the sampling blade tube away from the sharpened end, an air bag is fixedly connected to the upper end of the air tube, a one-way air valve is provided on the air bag, and an adsorption block slidably connected inside the sampling blade tube is fixedly connected to the lower end of the air tube, the adsorption block having an air chamber inside, and an adsorption hole on the bottom surface of the adsorption block.

[0006] As an improvement, limiting blocks are fixedly connected to both sides of the slider, and limiting sliding holes that cooperate with the limiting blocks are provided on both sides of the fixed housing. A return spring is fixedly connected between the lower end of the slider and the bottom surface of the movable groove.

[0007] As an improvement, a ring-shaped cutter is slidably sleeved on the outer wall of the support boss, and a connecting block is fixedly connected to the inner wall of the ring-shaped cutter. The outer wall of the support boss is provided with a groove that mates with the connecting block, and a support spring that mates with the connecting block is fixedly connected in the groove.

[0008] As an improvement, a connecting block is fixedly connected to one side of the sampling blade, and a connecting slot that mates with the connecting block is provided on one side of the slider. A magnetic block is fixedly connected to one end of the connecting block, and the slider is made of iron.

[0009] As an improvement, a fixing bolt is threadedly connected to one side of the sampling blade cylinder, and a positioning groove that mates with the fixing bolt is provided on one side of the adsorption block.

[0010] The advantages of this invention compared to existing technologies are as follows: When slicing, the blade is placed between the sampling knife tube and the support base, and the sampling knife tube is pressed down to cut the slice, so that the slice is placed inside the sampling knife tube. The air bag is pressed to release the adsorption chamber inside the adsorption block to negative pressure, and the air tube is pressed down to push the adsorption block to contact the slice. The air bag is released to allow the slice to be adsorbed on the bottom surface of the adsorption block. The sampling knife tube is then removed from one side of the fixed shell, and the slice is placed in the sampling dish. This method is time-saving, labor-saving, and easy to operate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, a forestry plant quarantine sample collection device includes a handle 1, a fixed housing 2 on one side of the handle 1, a movable groove on one side of the fixed housing 2, a slider 4 slidably connected in the movable groove, limiting blocks 17 fixedly connected on both sides of the slider 4, limiting sliding holes 18 that cooperate with the limiting blocks 17 on both sides of the fixed housing 2, and a return spring 5 fixedly connected between the lower end of the slider 4 and the bottom surface of the movable groove.

[0018] A detachable sampling blade cylinder 3 is fixedly connected to one side of the slider 4. A connecting block 14 is fixedly connected to one side of the sampling blade cylinder 3. A connecting slot 15 that mates with the connecting block 14 is provided on one side of the slider 4. A magnetic block 16 is fixedly connected to one end of the connecting block. The slider 4 is made of iron. The lower end of the sampling blade cylinder 3 is a sharpened end. A support base is fixedly connected to the lower end of the fixed housing 2. A support boss 7 that mates with the sampling blade cylinder 3 is fixedly connected to the upper end of the support base. A ring-shaped cutter 11 is slidably sleeved on the outer wall of the support boss. A connecting block 12 is fixedly connected to the inner wall of the ring-shaped cutter 11. A groove 23 that mates with the connecting block 12 is provided on the outer wall of the support boss 7. A support spring 13 that mates with the connecting block 12 is fixedly connected in the groove 23.

[0019] An air tube 8 is slidably inserted into the end of the sampling tube 3 away from the blade. An air bag 10 is fixedly connected to the upper end of the air tube 8. A one-way air valve is provided on the air bag 10. An adsorption block 9 is slidably connected to the lower end of the air tube 8 inside the sampling tube 3. An air chamber 21 is provided inside the adsorption block 9. An adsorption hole 22 is provided on the bottom surface of the adsorption block 9. A fixing bolt 19 is threadedly connected to one side of the sampling tube 3. A positioning groove 20 that cooperates with the fixing bolt 19 is provided on one side of the adsorption block 9.

[0020] In practical use, the plant leaf to be quarantined is placed between the sampling tube 3 and the support base 6. The air bladder 10 is squeezed to expel the air from the air bladder 10 and the air chamber 21, and the sampling tube 3 is pushed downward toward the leaf. The sampling tube 3 drives the slider 4 to slide downward and compress the return spring 5. When the lower end of the sampling tube 3 contacts the leaf, the bottom surface of the leaf is squeezed to press against the upper end of the annular cutter 11. Under the elastic force of the support spring 13, the leaf is cut and the slice is placed inside the sampling tube 3. The fixing bolt 19 is loosened and the air tube 8 is pushed downward, which causes the adsorption block 9 to contact the upper end of the slice. The air bladder 10 is released and the airflow enters from the adsorption hole 22, spreading the slice flat and adsorbing it on the lower end of the adsorption block 9.

[0021] When it is necessary to place the slice in the sampling dish, pull the sampling knife tube 3 outward forcefully, so that the connecting insert 14 drives the magnetic block 16 to be pulled out and separated from the connecting slot 15, so that the lower end of the sampling knife tube 3 is aligned with the sampling dish, push the air tube 8 downward, so that the adsorption block 9 drives the slice close to the sampling dish, press the air bag 10, so that the airflow is sprayed out from the adsorption hole 22, blowing the slice into the sampling dish, thus completing the sampling of plant leaves.
