Description

Technical Field

[0001] This application relates to the field of forestry testing technology, and in particular to a rapid sampling device for pine wilt disease-infected wood blocks. Background Technology

[0002] Pine wilt disease is a major invasive alien species in my country and has been listed as a forest quarantine target both domestically and internationally. To further improve the prevention and control of pine wilt disease, effective detection is an indispensable and primary task. Currently, there are two main methods for sampling suspected pine wilt disease-infected trees: one is to directly drill for sawdust, and the other is to cut sections of wood.

[0003] Currently, Chinese patent CN118225482A discloses a portable device and method for rapid sampling and sample preparation for pine wood nematode detection. It employs a combination of functions including an electric drill, a wood chip drill bit, a sawdust drill bit, a collection hood, and a sample washing filter bag to achieve integrated sampling and sample preparation, thus improving overall efficiency. However, the connection between the collection hood and the electric drill uses only a simple nested joint. During sampling, as the electric drill starts, the collection hood rotates along with the drill bit, causing rotational wear between the collection hood and the sample wood, reducing the lifespan of the collection hood. Therefore, further improvements are needed. Utility Model Content

[0004] To reduce the possibility of wear and tear on the collection cover, this application provides a rapid sampling device for pine wood blocks infected with pine wilt disease.

[0005] The technical solution of the rapid sampling device for pine wood blocks infected with pine wilt disease provided in this application is as follows:

[0006] A rapid sampling device for pine wood nematode diseased wood blocks includes a drill gun, a drill rod for drilling wood chips from diseased wood blocks, and a collection cover for collecting the drilled wood chips. The drill rod is detachably connected to the output end of the drill gun, and the collection cover is rotatably sleeved on the drill rod.

[0007] By adopting the above technical solution, the collection cover is rotatably fitted onto the drill rod, allowing the collection cover to rotate relative to the drill rod. When sampling diseased wood blocks, the operator holds the collection cover with one hand, so that the open end of the collection cover abuts against the diseased wood block, and uses the other hand to hold the drill gun and drive the drill rod to rotate to drill out wood chips. This reduces the possibility of rotational wear between the collection cover and the sample wood, and improves the service life of the collection cover.

[0008] Preferably, one end of the collecting cover is coaxially fixedly connected to a bearing seat, the bearing seat is coaxially rotatably embedded with a bearing body, and the drill rod is coaxially inserted through the inner hole of the bearing body.

[0009] By adopting the above technical solution, the bearing housing provides an installation carrier for the bearing body, and the drill rod is coaxially inserted into the inner hole of the bearing body. This structure enables a stable relative rotational connection between the collection hood and the drill rod, thereby reducing the possibility of rotational wear of the collection hood at the connection position with the drill rod and improving the stability and service life of the collection hood.

[0010] Preferably, the bearing housing is provided with a spacer located between the bearing body and the drill gun, and the spacer has a first through hole coaxially provided for the drill shank of the drill rod to pass through.

[0011] By adopting the above technical solution and adding a spacer, the possibility of direct contact between the bearing body and the output end face of the drill gun can be effectively prevented.

[0012] Preferably, one end of the septum is coaxially fixedly connected to a spacer sleeve, the spacer sleeve is inserted into the inner hole of the bearing body, and the drill shank of the drill rod passes through the inner hole of the spacer sleeve.

[0013] By adopting the above technical solution, since the minimum size of the bearing body is limited and the outer diameter of the drill shank is smaller than the inner diameter of the bearing body, a spacer is added to the inner hole of the bearing body to fill the gap between the drill rod and the inner hole of the bearing body. The spacer not only provides support for the drill rod, but also ensures smooth rotation between the two by inserting into the inner hole of the bearing body, avoiding the risk of component damage caused by vibration, and improving the overall stability and reliability of the sampling process.

[0014] Preferably, the bearing housing is provided with a sealing gasket, and the sealing gasket has a second through hole coaxially provided for the drill shank of the drill rod to pass through.

[0015] By adopting the above technical solution, by setting a sealing gasket and opening a second through hole on the sealing gasket for the drill shank to pass through, the sealing performance between the drill rod and the bearing housing is improved.

[0016] Preferably, the sealing gasket is an elastic gasket, and under normal conditions, the inner diameter of the second perforation is smaller than the outer diameter of the drill shank of the drill rod.

[0017] By adopting the above technical solution, the sealing gasket adopts an elastic gasket design, and under normal conditions, the inner diameter of the second perforation is smaller than the outer diameter of the drill shank of the drill rod. After the drill rod is inserted into the second perforation, the inner wall of the second perforation tightly covers the outer peripheral wall of the drill rod, effectively improving the sealing performance.

[0018] Preferably, the bearing housing is coaxially fixedly connected to an insert post built into the collection cover, the insert post has a third through hole for the drill shank of the drill rod to pass through, and the sealing gasket is coaxially fixedly connected to a ferrule fitted onto the insert post.

[0019] By adopting the above technical solution, the ferrule is fitted onto the insert post, thereby installing the sealing gasket on the inner side of the bearing housing, effectively reducing the possibility of debris entering the bearing body during the sampling process and ensuring the smooth rotation of the bearing body.

[0020] Preferably, the outer peripheral wall of the bearing housing is fixedly connected with a lug plate, and at least two lug plates are provided, with a hanging rope or hanging rod provided between the two lug plates.

[0021] By adopting the above technical solution, at least two ear plates are added to the outer peripheral wall of the bearing housing for fixed connection, and a hanging rope or hanging rod is set between the two ear plates, so that the collection cover can be hung in a designated position when not in use, which facilitates storage and management and improves the ease of use.

[0022] Preferably, the end of the collecting cover away from the bearing seat is coaxially fixedly fitted with a mounting ring plate, and the mounting ring plate is fixedly connected with a guide rod. The axial direction of the guide rod is parallel to the axial direction of the collecting cover. The outer side wall of the bearing seat is fixedly connected with a guide plate, and the guide rod slides axially through the guide plate.

[0023] By adopting the above technical solution, adding guide rods and guide plates provides stable support for the collection hood, effectively reducing the possibility of the front end of the collection hood bending downwards and reducing the possibility of the inner wall of the collection hood contacting the cutting part of the drill rod.

[0024] In summary, this utility model has the following beneficial effects:

[0025] 1. The collection hood is rotatably mounted on the drill rod, allowing the collection hood to rotate relative to the drill rod. When sampling diseased wood blocks, the operator holds the collection hood with one hand, so that the open end of the collection hood abuts against the diseased wood block, and uses the other hand to hold the drill gun and drive the drill rod to rotate to drill out wood chips. This reduces the possibility of rotational wear between the collection hood and the sample wood, and improves the service life of the collection hood.

[0026] 2. Due to the limited minimum size of the bearing body and the fact that the outer diameter of the drill shank of the drill rod is smaller than the inner diameter of the bearing body, a spacer is added to the inner hole of the bearing body to fill the gap between the drill rod and the inner hole of the bearing body. The spacer not only provides support for the drill rod, but also ensures smooth rotation between the two by inserting into the inner hole of the bearing body, avoiding the risk of component damage caused by vibration and improving the overall stability and reliability of the sampling process.

[0027] 3. The sealing gasket adopts an elastic gasket design, and under normal conditions, the inner diameter of the second perforation is smaller than the outer diameter of the drill shank of the drill rod. After the drill rod is inserted into the second perforation, the inner wall of the second perforation tightly covers the outer peripheral wall of the drill rod, effectively improving the sealing performance.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] Example 1:

[0036] This application discloses a rapid sampling device for wood blocks infected with pine wilt disease, referring to... Figure 1 The system includes a drill rig 1, a drill rod 2 for drilling wood chips from diseased wood blocks, and a collection cover 3 for collecting the drilled wood chips. The collection cover 3 is rotatably fitted onto the drill rod 2. The drill rod 2 is detachably connected to the output end of the drill rig 1. The installation structure between the drill rig 1, the drill handle of the drill rod 2, and the drill rig 1 is existing technology and will not be described in detail here.

[0037] Reference Figure 1 , Figure 2 The collecting cover 3 is a funnel-shaped cover with a diameter that gradually decreases from one end to the other. In this embodiment, the collecting cover 3 is made of soft silicone and has a corrugated structure, allowing it to be compressed axially. One end of the collecting cover 3 is open, and a bearing seat 4 is coaxially fixedly connected to the outer end face of the other end of the collecting cover 3. The end face of the bearing seat 4 away from the collecting cover 3 has a bearing hole 41 axially formed. The bearing seat 4 is provided with a bearing body 42 that is coaxially rotatably embedded in the bearing hole 41. The outer end face of the bearing body 42 is flush with the end face of the bearing seat 4 away from the collecting cover 3.

[0038] Reference Figure 2 , Figure 3 The bearing housing 4 is provided with a spacer 43 located between the bearing body 42 and the drill gun 1. The spacer 43 is a plastic spacer, and a first through hole 431 is coaxially provided on the spacer 43 for the drill shank of the drill rod 2 to pass through. One end of the spacer 43 abuts against the end face of the bearing body 42, and the other end of the spacer 43 abuts against the output end face of the drill gun 1. A spacer sleeve 432 is coaxially fixedly connected to one end of the spacer 43. The spacer sleeve 432 and the spacer 43 are integrally formed. The spacer sleeve 432 is inserted into the inner hole of the bearing body 42, and the drill shank of the drill rod 2 passes through the inner hole of the spacer sleeve 432.

[0039] Reference Figure 4 The bearing housing 4 is provided with a sealing gasket 44 built into the collecting cover 3. The sealing gasket 44 has a second through hole 441 coaxially formed for the drill shank of the drill rod 2 to pass through. The sealing gasket 44 is an elastic gasket. Under normal conditions, the inner diameter of the second through hole 441 is smaller than the outer diameter of the drill shank of the drill rod 2. The installation structure of the sealing gasket 44 and the bearing housing 4 is as follows: the end face of the bearing housing 4 away from the septum 43 is coaxially fixedly connected to the insert post 45 built into the collecting cover 3. The insert post 45 and the bearing housing 4 are integrally formed. The insert post 45 has a third through hole 451 that communicates with the bearing hole 41 for the drill shank of the drill rod 2 to pass through. The sealing gasket 44 is coaxially fixedly connected to the retaining sleeve 442 fitted onto the insert post 45. The retaining sleeve 442 and the sealing gasket 44 are integrally formed. The drill shank of the drill rod 2 passes through the inner hole of the retaining sleeve 442. The end of the insert 45 has a protruding ring with a limiting ring 452, and one end of the sleeve 442 has an integrally formed retaining ring 443 on its inner circumferential wall. After the sleeve 442 is fitted onto the insert 45, the retaining ring 443 abuts against the end face of the limiting ring 452 near the bearing seat 4, effectively preventing the sleeve 442 from falling out of the insert 45 in the opposite direction. In this embodiment, the retaining ring 443 and the limiting ring 452 can rotate relative to each other.

[0040] Reference Figure 1 , Figure 2 The outer peripheral wall of the bearing housing 4 is fixedly connected with a lug plate 46. At least two lug plates 46 are provided. The two lug plates 46 are symmetrically distributed along the axis of the bearing housing 4. The lug plate 46 has a fourth through hole 461. A suspension member 47 is provided between the through holes of the two lug plates 46. The suspension member 47 is a hanging rope or a hanging rod.

[0041] The implementation principle of a rapid sampling device for pine wood blocks infected with pine wilt disease according to an embodiment of this application is as follows: After the sealing gasket 44, bearing body 42, and septum 43 are all installed in the bearing seat 4, one end of the drill shank of the drill rod 2 is inserted from the open end of the collection cover 3, and the drill shank of the drill rod 2 passes through the second through hole 441, the third through hole 451, the inner hole of the spacer sleeve 432, and the first through hole 431 in sequence. The drill shank that passes through the septum 43 is installed on the output end of the drill gun 1, so that the end face of the septum 43 abuts against the output end face of the drill gun 1, thereby realizing the rotation of the collection cover 3 onto the drill rod 2. This design allows the collection hood 3 to rotate relative to the drill rod 2. When sampling diseased wood blocks, the operator holds the collection hood 3 with one hand, so that the open end of the collection hood 3 abuts against the diseased wood block, and uses the other hand to hold the drill gun 1 and drive the drill rod 2 to rotate to drill wood chips. This reduces the possibility of rotational wear between the collection hood 3 and the sample wood. In addition, a bearing body 42 is added to form a stable relative rotational connection between the collection hood 3 and the drill rod 2, thereby reducing the possibility of rotational wear at the connection point between the collection hood 3 and the drill rod 2, and improving the stability and lifespan of the collection hood 3.

[0042] Example 2:

[0043] The difference from Example 1 is that, referring to Figure 5 A mounting ring plate 31 is coaxially fixedly sleeved at the open end of the collection hood 3. A guide rod 32 is fixedly connected to the mounting ring plate 31. The axial direction of the guide rod 32 is parallel to the axial direction of the collection hood 3. A guide plate 48 is fixedly connected to the outer wall of the bearing seat 4. The guide rod 32 slides through the guide plate 48 along the axial direction. The addition of the guide rod 32 and the guide plate 48 provides stable support for the collection hood 3, effectively reducing the possibility of the front end of the collection hood 3 bending downwards and reducing the possibility of the inner wall of the collection hood 3 contacting the cutting part of the drill rod 2.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
