Description

Technical Field

[0001] This utility model relates to the field of pear fire blight monitoring and integrated prevention and control technology, specifically a pear fire blight sample collection device. Background Technology

[0002] Pear fire blight is a disease caused by *Erwinia amylovora*, affecting pears. It primarily damages flowers, fruits, and leaves, causing them to quickly turn blackish-brown and wither, resembling fire damage, yet remaining on the tree, hence the name. Internationally, the symptoms are classified into five stages based on the affected parts: flower blight, canker blight, branch blight, injury blight, and rootstock blight.

[0003] Early symptoms of pear blight are not obvious, but later they become very typical and can be distinguished by the naked eye. However, there are other diseases with similar symptoms, such as pear twig blight. During identification, it is necessary to differentiate between these diseases and pear twig blight. However, simple visual observation cannot accurately distinguish them; it is necessary to collect samples from the symptomatic diseased areas and then confirm the diagnosis through immunological tests. Since the disease is still located on the tree, a sample collection device is required. Existing collection devices include a branch and leaf sampling tool disclosed in Chinese Patent Publication No. CN202547968U. The branch and leaf sampling tool includes a handheld rod with a branch-breaking fork at the top. The branch-breaking fork consists of a first fork side, a second fork side, and a fork base, with the first and second fork sides erected parallel to each other on the fork base.

[0004] While this tool is convenient for collecting branches and leaves, the process of breaking branches with a fork can easily lead to contact with other parts or other host plants, causing the disease to spread from the affected area to other branches and leaves. Furthermore, if other branches and leaves have other diseases, the contamination can affect the accuracy of subsequent testing. Therefore, we propose a pear blight sample collection device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a pear blight sample collection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pear blight sample collection device, comprising a support cylinder, one end of which is fixedly connected to a rope winding assembly, the rope winding assembly being fixedly connected to one end of an operating rope, the other end of which is slidably sleeved with a telescopic rod, the end of the telescopic rod away from the support cylinder being fixedly sleeved with a support base, one end of several transmission bars being hinged to the support base, the other end of each transmission bar being fixedly connected to a cutter, the middle of each transmission bar being hinged to one end of an active connecting rod through a through-hole, the other end of the active connecting rod being hinged to a collection assembly, and the collection assembly being slidably connected to the telescopic rod.

[0007] Preferably, the side of the support cylinder away from the rope winding assembly is connected to a positioning bolt via a threaded structure.

[0008] Preferably, the rope winding assembly includes a bracket, a winding roller, and a handwheel. The bracket is fixedly connected to one end of the support cylinder, and the winding roller is rotatably mounted on the bracket.

[0009] Preferably, the telescopic rod has guide grooves recessed at both ends on the side away from the support cylinder, and the guide grooves slidably engage with the acquisition component. The telescopic rod has a hollow wire cavity inside the side away from the support cylinder, and the two ends of the wire cavity are respectively connected to the guide grooves. A guide wheel is rotatably installed on both sides inside the wire cavity.

[0010] Preferably, the telescopic rod has a hollow cylindrical movable hole inside, the wire cavity is connected to the cylindrical movable hole, and guide wheels are rotatably installed on both sides of the connection position.

[0011] Preferably, the acquisition component includes a movable ring, a slider, and a return spring. The movable ring is slidably sleeved with a telescopic rod. One end of an active connecting rod is hinged to the movable ring. Slider blocks are fixedly connected to both sides of the inner wall of the movable ring. The slider blocks are slidably engaged with guide grooves. One end of the slider away from the support cylinder is fixedly connected to one end of the return spring. The other end of the return spring is fixedly connected to the inner wall of the guide groove. One end of the slider is fixedly connected to one end of a branch rope. The branch ropes slide through the wire cavity and the ends of the branch ropes are fixedly connected to the ends of the operating ropes.

[0012] Preferably, the transmission bar has an arc-shaped structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the arc-shaped transmission bar forms a spherical structure, which then wraps and isolates the collection location, preventing the collected sample from contacting and contaminating other parts of the host plant or other hosts. After the transmission bar forms a spherical structure, the flower, fruit, or leaf of the host plant is cut off by a cutter fixed to the end, so that the collected sample falls inside the spherical structure, which facilitates sample collection and ensures the accuracy of subsequent test results.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a pear blight sample collection device, including a support cylinder 1. One end of the support cylinder 1 is fixedly connected to a rope winding assembly 4. The rope winding assembly 4 is fixedly connected to one end of an operating rope 5. The other end of the support cylinder 1 is slidably sleeved with a telescopic rod 3. The end of the telescopic rod 3 away from the support cylinder 1 is fixedly sleeved with a support base 10. Several transmission bars 8 are respectively hinged to one end on the support base 10. The other end of the transmission bars 8 is fixedly connected to a cutter 9. The middle part of each transmission bar 8 is hinged to one end of an active connecting rod 7 through a through-hole. The other end of the active connecting rod 7 is hinged to a collection assembly 6. The collection assembly 6 is slidably connected to the telescopic rod 3.

[0020] Based on the height of the sample collection point, the telescopic rod 3 is pulled out from the support cylinder 1, allowing the transmission bar 8 to reach the sample. Then, the positioning bolt 2 is tightened, with its end contacting the outer wall of the telescopic rod 3, thus fixing its position. Next, the support cylinder 1 is held, and the transmission bar 8 is inserted into the collection position. Under the elastic force of the return spring 63 of the collection component 6, the movable ring 61 drives the active connecting rod 7 to pull the transmission bar 8 open, allowing the flower, fruit, or leaf to be collected to be located within it. To ensure isolation, a protective net can be fixedly connected between adjacent transmission bars 8, further improving the isolation effect. Then, the rope winding component 4 is manually operated by turning the handwheel 43. The handwheel 43 drives the fixed winding roller 42 to rotate, and the winding roller 42... Rope 5 is wound up, pulling the branch rope 51 fixed at its end. The branch rope 51 drives the slider 62 of the collection component 6 to move. The slider 62 compresses the return spring 63. The branch rope 51 is guided by guide wheel 1 33 and guide wheel 2 34 respectively, which improves the stability of the movement. The slider 62 drives the fixed movable ring 61 to move. The movable ring 61 drives the hinged active linkage 7 to move. The active linkage 7 then pushes the transmission bars 8 closer together to form a spherical structure. The cutter 9 fixed at the end of the transmission bar 8 cuts the flower, fruit or leaf root, so that the collected sample falls inside the spherical structure of the transmission bar 8. The isolation net prevents the sample from leaking out from the gap between the transmission bars 8, which facilitates sample collection. The isolated collection method ensures the accuracy of the subsequent test results.

[0021] Example 2

[0022] Reference Figure 1-2 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the side of the support cylinder 1 away from the rope winding assembly 4 is connected to the positioning bolt 2 by a threaded structure. According to the height position of the sample to be collected, the telescopic rod 3 is pulled out from the support cylinder 1, so that the transmission bar 8 can reach the sample to be collected. Then, by tightening the positioning bolt 2, the end of the positioning bolt 2 abuts against the outer wall of the telescopic rod 3, thereby fixing the position of the telescopic rod 3. The setting of the positioning bolt 2 facilitates the collection of samples at different heights.

[0023] Specifically, the rope winding assembly 4 includes a bracket 41, a winding roller 42, and a handwheel 43. The bracket 41 is fixedly connected to one end of the support cylinder 1, and the winding roller 42 is rotatably mounted on the bracket 41. One end of the winding roller 42 is fixedly connected to the handwheel 43, and the winding roller 42 is fixedly connected to one end of the operating rope 5.

[0024] Manually operate the rope winding assembly 4 by manually turning the handwheel 43. The handwheel 43 drives the fixed winding roller 42 to rotate, and the winding roller 42 winds up the operating rope 5.

[0025] Specifically, the telescopic rod 3 has guide grooves 32 recessed at both ends on the side away from the support cylinder 1. The guide grooves 32 are slidably engaged with the acquisition component 6. The telescopic rod 3 has a hollow wire cavity 31 inside the side away from the support cylinder 1. The two ends of the wire cavity 31 are respectively connected to the guide grooves 32. Guide wheels 33 are rotatably installed on both sides inside the wire cavity 31.

[0026] Furthermore, the telescopic rod 3 has a hollow cylindrical movable hole inside, and the wire cavity 31 is connected to the cylindrical movable hole, with guide wheels 34 rotatably installed on both sides of the connection position.

[0027] Specifically, the acquisition component 6 includes a movable ring 61, a slider 62, and a return spring 63. The movable ring 61 is slidably sleeved with the telescopic rod 3. One end of the active connecting rod 7 is hinged to the movable ring 61. The slider 62 is fixedly connected to both sides of the inner wall of the movable ring 61. The slider 62 is slidably engaged with the guide groove 32. One end of the slider 62 away from the support cylinder 1 is fixedly connected to one end of the return spring 63. The other end of the return spring 63 is fixedly connected to the inner wall of the guide groove 32. One end of the slider 62 is fixedly connected to one end of the branch rope 51. The branch rope 51 slides into the wire cavity 31 and the ends of the branch rope 51 are fixedly connected to the ends of the operating rope 5.

[0028] When the operating rope 5 is wound up, the branch rope 51 fixed at the end is pulled. The branch rope 51 drives the slider 62 of the collection component 6 to move. The slider 62 compresses the return spring 63. The branch rope 51 is guided by the guide wheel 33 and the guide wheel 34 respectively, which improves the stability of the movement. The slider 62 drives the fixed movable ring 61 to move. The movable ring 61 drives the hinged active linkage 7 to move. The active linkage 7 then pushes the transmission bars 8 to move closer to each other to form a spherical structure. The cutter 9 fixed at the end of the transmission bar 8 cuts the flower, fruit or leaf root position, so that the collected sample falls into the spherical structure of the transmission bar 8. And through the set isolation net, the sample is prevented from leaking out from the gap between the transmission bars 8, which facilitates the collection of the sample. The isolated collection method ensures the accuracy of the subsequent test results.

[0029] Specifically, the transmission bar 8 has an arc-shaped structure. The arc-shaped rigid structure forms a spherical structure when it is retracted. At the same time, in order to ensure the isolation effect, a protective net can be fixedly connected between two adjacent transmission bars 8, which further improves the isolation effect and can also prevent the collected samples from leaking out from the gaps between the transmission bars 8.

[0030] Example 3

[0031] Reference Figure 1-2This is the third embodiment of the present invention. Based on the previous two embodiments, in use, according to the height of the sample to be collected, the telescopic rod 3 is pulled out from the support cylinder 1, allowing the transmission bar 8 to reach the sample. Then, by tightening the positioning bolt 2, the end of the positioning bolt 2 abuts against the outer wall of the telescopic rod 3, thus fixing the position of the telescopic rod 3. Then, holding the support cylinder 1, the transmission bar 8 is inserted into the collection position. Under the elastic force of the return spring 63 of the collection component 6, the movable ring 61 drives the active connecting rod 7 to pull the transmission bar 8 open, allowing the flower, fruit, or leaf to be collected to be located within the transmission bar 8. Simultaneously, to ensure the isolation effect, a protective net can be fixedly connected between two adjacent transmission bars 8, further improving the isolation effect. Then, the rope winding component 4 is manually operated by manually turning the handwheel 43. The handwheel 43 drives the fixed winding roller 42 to rotate. 2. The operating rope 5 is wound up, pulling the branch rope 51 fixed at the end. The branch rope 51 drives the slider 62 of the collection component 6 to move. The slider 62 compresses the return spring 63. The branch rope 51 is guided by the guide wheel 1 33 and the guide wheel 2 34 respectively, which improves the stability of the movement. The slider 62 drives the fixed movable ring 61 to move. The movable ring 61 drives the hinged active linkage 7 to move. The active linkage 7 then pushes the transmission bars 8 to move closer to each other to form a spherical structure. The cutter 9 fixed at the end of the transmission bar 8 cuts the flower, fruit or leaf root position (the cutter 9 can be designed to be replaceable to prevent cross-contamination). The collected sample falls into the spherical structure of the transmission bar 8. And through the set isolation net, the sample is prevented from leaking out from the gap between the transmission bars 8, which facilitates the collection of the sample. The isolated collection method ensures the accuracy of the subsequent test results.
