Abstract
Description
Technical Field
[0001] This application relates to a detection device, and more particularly to an integrated machine for detecting pine wilt disease. Background Technology
[0002] Pine wilt nematode is a common parasite of pine trees. The adult nematode is about 1 mm long. The female's tail is nearly conical with a rounded end; the male's tail resembles a bird's claw and curves ventrally. It is transmitted by vector insects such as the pine sawyer beetle, causing pine wilt disease. Once infected, the needles turn yellowish-brown or reddish-brown, the entire tree dries up and dies, eventually rotting. Pine wilt nematode is usually detected using a PCR instrument. However, PCR instruments are typically placed in laboratories, requiring samples to be collected from the field, pre-treated, and then tested, which affects detection efficiency. Summary of the Invention
[0003] To improve the detection efficiency of pine wilt disease, this application provides an integrated pine wilt disease detection machine.
[0004] This application provides an integrated pine wilt nematode detection machine, which adopts the following technical solution:
[0005] A pine wilt disease detection integrated machine includes a sampling device, a processing device, and a detection device. The processing device is disposed on the detection device, and the sampling device is slidably disposed on the processing device. The processing device is provided with a driving component for driving the sampling device to slide, and the driving component is connected to the sampling device.
[0006] By adopting the above technical solution, the sampling device is first moved by the driving component to sample different parts of the pine wood. Then, the sample is pre-processed by the processing device. Finally, the pre-processed sample is tested by the detection device. Pine wood can be tested anytime and anywhere, which is convenient and fast, thereby improving the detection efficiency.
[0007] In one specific implementation, the processing device includes a processing chamber disposed on the detection device. The processing chamber has a processing channel communicating with the detection device. A first annular groove is formed on the peripheral wall of the processing channel. A first rotating ring is rotatably connected to the groove wall of the first annular groove. A first worm gear is connected to the outer wall of the first rotating ring. A first motor is mounted on the processing chamber. A first worm is coaxially connected to the motor shaft of the first motor and meshes with the first worm gear. A processing tube is disposed on the peripheral wall of the processing channel. An insertion block is disposed on the inner wall of the first rotating ring. A slot for inserting the insertion block is formed on the processing tube. A heating tube is installed inside the processing chamber.
[0008] By adopting the above technical solution, the obtained wood chip sample is added to the processing tube, which contains lyophilized lysis solution powder, and then water is added. The motor shaft of the first motor drives the first worm, the first worm wheel, and the first rotating ring to rotate in sequence. With the cooperation of the insert and the slot, the first rotating ring drives the processing tube to rotate centrifugally. While rotating, the heating tube heats the processing tube, first at 65°C for 25 minutes, and then at 95°C for 5 minutes. The processing tube is then pulled out, and the wood chips are separated to the bottom of the processing tube using an inner tube with a 500-mesh sieve. The upper clear liquid is poured into the detection device for detection.
[0009] In one specific implementation, a second annular groove communicating with the processing channel is formed on the top wall of the processing chamber, a second rotating ring is rotatably connected to the groove wall of the second annular groove, a locking block is connected to the processing tube, and a locking slot for the locking block to be inserted is formed on the second rotating ring, the locking slot being arranged opposite to the locking block.
[0010] By adopting the above technical solution, the cooperation of the card block and the card slot facilitates the rotation of the processing tube by the second rotating ring and the installation and removal of the processing tube. The setting of the second rotating ring improves the stability of the rotation of the processing tube. The card slot and the insertion block are set opposite to each other, which plays a certain guiding role and makes it easy to insert the insertion block into the slot.

A first rotating rod is hinged to the lifting block, a first telescopic rod is slidably connected to the first rotating rod, a second rotating rod is hinged to the first telescopic rod, a second telescopic rod is slidably connected to the second rotating rod, a sampling tube is rotatably disposed on the second telescopic rod, and an adsorption element for adsorbing the sawdust in the sampling tube is disposed on the processing chamber.
[0012] By adopting the above technical solution, the sampling tube is placed against the pine wood, and then an electric drill is used to drill. During the drilling process, the adsorption component is used to suck up the sawdust in the sampling tube. The cooperation of the first rotating rod, the first telescopic rod, the second rotating rod, and the second telescopic rod makes it convenient to sample different positions at the same height of the pine wood.
[0013] In one specific implementation, the adsorption element includes an exhaust fan installed on the processing chamber. The air inlet of the exhaust fan is connected to a feed hose, and the air outlet of the exhaust fan is connected to a discharge hose. The discharge hose is inserted into the processing tube. A connecting pipe is connected to the sampling tube, and a protruding ring is provided on the connecting pipe. The feed hose is sleeved on the connecting pipe.
[0014] By adopting the above technical solution, the drilled wood chips are sucked into the processing pipe by a blower; the connection between the connecting pipe and the convex ring facilitates the installation and removal of the feed hose and the sampling pipe.
[0015] In one specific implementation, a first sliding groove is formed on the end wall of the first rotating rod, and a first limiting groove is formed on the groove wall of the first sliding groove. The first telescopic rod is slidably connected to the groove wall of the first sliding groove, and a first limiting block is connected to the first telescopic rod, which is slidably connected to the groove wall of the first limiting groove. A second sliding groove is formed on the end wall of the second rotating rod, and a second limiting groove is formed on the groove wall of the second sliding groove. The second telescopic rod is slidably connected to the groove wall of the second sliding groove, and a second limiting block is connected to the second telescopic rod, which is slidably connected to the groove wall of the second limiting groove.
[0016] By adopting the above technical solution, the stability of the sliding of the first telescopic rod is improved by utilizing the cooperation of the first limiting block and the first limiting groove, and the first telescopic rod can also be prevented from sliding out of the first sliding groove; by utilizing the cooperation of the second limiting block and the second limiting groove, the stability of the sliding of the second telescopic rod is improved, and the second telescopic rod can also be prevented from sliding out of the second sliding groove.

[0018] By adopting the above technical solution, the motor shaft of the second motor drives the second worm, the second worm wheel, and the threaded rod to rotate in sequence. With the cooperation of the guide rod and the guide groove, the lifting block has a certain limiting effect, so that the threaded rod drives the lifting block to slide and completes the sliding adjustment of the lifting block.
[0019] In one specific implementation, the detection device is provided with a fixing device for connecting with pine wood. The detection device has a third sliding groove. The fixing device includes a bidirectional screw rotatably connected to the wall of the third sliding groove. Two clamping blocks are threadedly connected to the bidirectional screw. The clamping blocks are slidably connected to the wall of the third sliding groove. Curved surfaces are provided on the opposite side walls of the two clamping blocks, and connecting straps are provided on the two clamping blocks. The two connecting straps are connected by buckles.
[0020] By adopting the above technical solution, rotating the bidirectional screw drives two clamping blocks to clamp the pine material, and then connecting the two clamping blocks with a connecting belt, thereby fixing the detection device on the pine material; the curved surface design increases the contact area between the clamping blocks and the pine material, thereby further improving the connection strength between the detection device and the pine material.

[0022] 1. In this application, the sampling device is first moved by the driving component to sample different parts of the pine wood. Then, the sample is pre-processed by the processing device.

[0023] 2. In this application, the obtained wood chip sample is added to the processing tube, which contains lyophilized lysis solution powder, and then water is added. The motor shaft of the first motor drives the first worm, the first worm wheel, and the first rotating ring to rotate in sequence. With the cooperation of the insert and the slot, the first rotating ring drives the processing tube to rotate centrifugally. While rotating, the heating tube heats the processing tube. First, it is heated at 65°C for 25 minutes, and then at 95°C for 5 minutes. The processing tube is then pulled out, and the wood chips are separated to the bottom of the processing tube using an inner tube with a 500-mesh sieve.
