Description

Technical Field

[0001] The utility model belongs to the technical field of forestry disease detection, and particularly relates to a sampling device for detecting pine wilt disease. Background Technique

[0002] Pine wilt disease, also known as pine wilt blight, is a devastating forest disease caused by Bursaphelenchus xylophilus. It is a major invasive alien species in China and has been listed as a forest plant quarantine object for both domestic and foreign. Since it was introduced into China in 1982, it has spread rapidly. It has occurred in 14 provinces (municipalities, autonomous regions) across the country, resulting in a large number of pine trees dying, causing serious damage to China's pine forest resources, natural landscapes and ecological environments, and causing serious economic and ecological losses. In order to determine whether a pine tree is healthy, it is necessary to sample and detect it, so a special sampling device is needed. The sampling device for detecting pine wilt disease is a tool specifically used to detect Bursaphelenchus xylophilus and its related diseases. When using the sampling device for detecting pine wilt disease, operators usually select suspected infected trees, extract samples by drilling, then put the samples into a collection tube, and record relevant information. The design of the sampling device aims to minimize damage to the trees while maximizing the collection of valuable information.

[0003] In the Chinese utility model patent with the publication number CN218411749U, a rapid sampling device suitable for detecting pine wilt disease is disclosed. This device samples the diseased area of pine trees by drilling, which reduces the damage to pine trees and does not affect the survival and growth of pine trees, and is suitable for the daily monitoring of existing pine wilt disease.

[0004] However, when this device is actually used, it needs to be held by hand for drilling. Since it is difficult to ensure the stability during drilling by hand-held method, it will not only reduce the efficiency of sampling pine trees, but also easily increase the damage to pine trees.

[0005] In summary, there is a need for a sampling device for detecting pine wilt disease that can maintain stability during drilling. Content of the Utility Model

[0006] The purpose of the utility model is to provide a sampling device for detecting pine wilt disease.

[0007] The technical solution adopted by the utility model to solve the above problems is: a sampling device for detecting pine wilt disease, comprising:

[0008] A U-shaped frame, a bracket is fixedly connected to the U-shaped frame, a push rod is slidably connected to the bracket, one end of the push rod is fixedly connected to a push plate, the push rod is also fixedly connected to a motor, and the end of the rotor of the motor is coaxially and fixedly connected to a drill bit;

[0009] Clamping assembly, the clamping assembly includes a one-way lead screw rotatably connected to a U-shaped frame, a moving block is threadedly connected to the one-way lead screw, a clamping plate is arranged on the inner side surface of the U-shaped frame, a cross bar is fixedly connected to one side of the clamping plate and is slidably connected between the cross bar and the U-shaped frame, and a first connecting rod is hinged between the cross bar and the moving block through a hinge member.

[0010] A further preferred technical solution is that: a debris collection box is fixedly connected to the U-shaped frame through a connecting plate, and a debris receiving plate is movably connected inside the debris collection box.

[0011] A further preferred technical solution is that: a T-shaped connecting frame is fixedly connected to the bottom of the debris receiving plate and is slidably connected between the T-shaped connecting frame and the debris collection box.

[0012] A further preferred technical solution is that: a connecting member is fixedly connected to the moving block, and a second connecting rod is hinged between the connecting member and the T-shaped connecting frame through a hinge member.

[0013] A further preferred technical solution is that: the cross section of the push rod is a rectangular structure.

[0014] A further preferred technical solution is that: a spring is sleeved on the push rod and both ends of the spring are fixedly connected to the push plate and the bracket respectively.

[0015] A further preferred technical solution is that: an anti-slip pad is arranged on the clamping plate.

[0016] A further preferred technical solution is that: a smooth inclined surface is arranged on the top of the debris receiving plate.

[0017] A further preferred technical solution is that: a baffle is fixedly connected to the top of the debris receiving plate.

[0018] A further preferred technical solution is that: two groups of clamping plates are arranged on the inner side surface of the U-shaped frame, and the anti-slip pads of the two groups of clamping plates are arranged oppositely.

[0019] In summary, the present utility model has the following beneficial effects:

[0020] 1. By rotating the one-way lead screw, the moving block threadedly connected thereto is driven to move outwards. By using the sliding fit between the cross bar and the U-shaped frame and the hinged action between the cross bar, the moving block and the first connecting rod, the two groups of clamping plates can be driven to move towards each other, so that the device can be clamped outside the pine tree trunk, thereby ensuring the stability during drilling and sampling of the pine tree. The added anti-slip pad can not only increase the friction between the device and the pine tree to improve the fixing effect, but also protect the pine tree from secondary damage.

[0021] 2. When the device is clamped outside the pine tree trunk, while the moving block is moving, it can also drive two sets of connecting pieces to move together. By using the hinged connection between the connecting pieces, the T-shaped connecting frame and the second connecting rod, the sliding fit between the T-shaped connecting frame and the debris collection box, and the movable fit between the debris receiving plate and the debris collection box, the debris receiving plate can be driven to move downward. At this time, the concave space formed between the surface of the debris receiving plate and the debris collection box can automatically collect the debris falling during drilling, thereby improving the practicability and convenience of the device. When the sampling is completed and the unidirectional lead screw is rotated to disassemble the device, the debris receiving plate can then push out the collected debris, thus achieving the purpose of automatic discharging.

[0029] Embodiment:

[0030] Please refer to Figures 1-4 , a sampling device for detecting pine wilt disease in this embodiment, includes:

[0031] U-shaped frame 1, one side of the U-shaped frame 1 is fixedly connected with a bracket, a push rod 2 is slidably connected to the bracket, one end of the push rod 2 is fixedly connected with a push plate, the other end of the push rod 2 is fixedly connected with a motor 3, the end of the rotor of the motor 3 is coaxially fixedly connected with a drill bit 4, the cross-section of the push rod 2 is a rectangular structure, which can ensure the horizontal and stable pushing of the drill bit 4. A spring 5 is sleeved outside the push rod 2, and both ends of the spring 5 are fixedly connected with the push plate and the bracket respectively, which is convenient for the drill bit 4 to automatically reset;

[0032] Clamping assembly, the clamping assembly includes a one-way lead screw 101 rotatably connected to one side of the U-shaped frame 1, a moving block 102 is threadedly connected to the outside of the one-way lead screw 101, clamping plates 103 are symmetrically arranged on the inner side surface of the U-shaped frame 1, one side of the clamping plate 103 is fixedly connected with a cross bar 104 and the cross bar 104 is slidably connected with the U-shaped frame 1, and a first connecting rod 105 is symmetrically hinged between the cross bar 104 and the moving block 102 through a hinge. The clamping plate 103 is designed with an arc-shaped structure to facilitate fitting the trunk of the pine tree. Anti-slip pads are added to the opposite surfaces of the two groups of clamping plates 103, which can not only increase the friction between the device and the pine tree to improve the fixing effect, but also the anti-slip pads can protect the pine tree and prevent it from being damaged again.

[0033] One side of the U-shaped frame 1 is fixedly connected with a debris collection box 201 through a connecting plate. A debris receiving plate 202 is movably connected inside the debris collection box 201. The bottom of the debris receiving plate 202 is fixedly connected with a T-shaped connecting frame 203 and the T-shaped connecting frame 203 is slidably connected with the debris collection box 201. One side of the moving block 102 is symmetrically fixedly connected with a connecting member 204, and a second connecting rod 205 is hinged between the connecting member 204 and the T-shaped connecting frame 203 through a hinge. The top of the debris receiving plate 202 is designed with a smooth inclined plane, which is convenient for the debris receiving plate 202 to automatically slide when it pushes the pine tree debris out of the debris collection box 201. Baffles 206 are fixedly connected to both sides of the top of the debris receiving plate 202, which can prevent the debris from falling outside the device when it is pushed out. The area of the debris receiving plate 202 is the same as the cross-sectional area of the inner cavity of the debris collection box 201.

[0034] In the embodiment of the present application, the implementation principle of a sampling device for detecting pine wilt disease is as follows: First, carry the device to the pine tree to be detected. Then, place the U-shaped frame 1 outside the trunk of the pine tree and at the same time make the trunk of the pine tree located between the two clamping plates 103. Subsequently, rotate the one-way lead screw 101. By rotating the one-way lead screw 101, the moving block 102 threadedly connected thereto moves outward. Utilizing the sliding fit between the cross bar 104 and the U-shaped frame 1 and the hinged connection between the cross bar 104 and the moving block 102 and the first link 105, the two clamping plates 103 can be driven to move towards each other, so that the device can be clamped outside the trunk of the pine tree. The anti-slip pad can increase the friction between the device and the trunk of the pine tree and prevent loosening during the sampling process. At the same time, during the movement of the moving block 102, the two connecting pieces 204 can also be driven to move together. Utilizing the hinged connection between the connecting piece 204 and the T-shaped connecting frame 203 and the second link 205, and the sliding fit between the T-shaped connecting frame 203 and the debris collection box 201 and the movable fit between the debris receiving plate 202 and the debris collection box 201, the debris receiving plate 202 can be driven to move downward. Then, start the motor 3. The motor 3 can drive the drill bit 4 to rotate at a high speed. After that, push the push rod 2 through the push plate. At this time, the drill bit 4 will continuously penetrate into the trunk of the pine tree. The debris falling during drilling will enter the recessed space formed between the surface of the debris receiving plate 202 and the debris collection box 201 for collection. Finally, when the sampling is completed, turn off the motor 3 and release the push plate. Under the elastic return action of the spring 5, the drill bit 4 will automatically reset. Then, reverse the one-way lead screw 101 to release the device. At this time, the debris receiving plate 202 can move vertically upward again to push out the collected debris, thus achieving the purpose of automatic discharging.

[0035] A further improvement lies in that the top of the baffle 206 is designed to be inclined inward, which can prevent debris from remaining on the top of the baffle 206.

[0036] In addition, as much as possible, the same or similar element symbols are used in the drawings and the description to refer to the same or similar parts or steps. The drawings are presented in a simplified form and are not drawn to an exact scale.
