Description

Technical Field

[0001] This utility model belongs to the field of plant sample sampling technology, and relates to a shear sampling device, particularly a shear sampling device that prevents air embolism in plants. Background Technology

[0002] Plant sample testing data can effectively corroborate relevant atmospheric and soil environmental monitoring data, making plant sample testing an indispensable part of environmental monitoring. The foundation of plant testing is plant sample collection, and currently, there are generally two types of devices for this purpose. One type includes a support rod and an arc-shaped cutting blade fixed to the support rod. During sampling, the plant sample is cut by hand, applied force directly to the support rod. This type of plant sample collection device is less commonly used due to its inconvenient construction and high labor intensity. The other type includes a support rod and a shearing blade hinged to the support rod. A corresponding pulling mechanism effectively drives the shearing blade to rotate, cutting or severing the plant sample, which significantly improves sampling convenience and reduces labor intensity.

[0003] A search revealed a Chinese patent document disclosing a plant sample collection device for environmental testing [Application No.: 201921065980.8; Publication No.: CN 210322348 U]. This device includes a support rod, a shearing mechanism, and a shearing control mechanism. The shearing mechanism comprises a positioning plate fixed to one side of the top of the support rod. A shearing clamp and a shearing shaft are fixed to the positioning plate. A shearing blade is slidably mounted on the shearing shaft. The shearing control mechanism includes a control rod hinged above the shearing blade. A corresponding pull rope is fixed to the bottom of the control rod. A limiting ring plate is fixed to the upper side wall of the connecting hole of the support rod. A corresponding limiting spring is installed between the spring clamp of the control rod and the limiting ring plate. This invention effectively limits the position of plant samples and, based on this limitation, drives the serrated blade to perform a back-and-forth motion to cut the plant samples, thereby significantly improving sampling efficiency and reducing sampling difficulty.

[0004] Although the patented blade with serrated edge can cut plant samples back and forth, thereby greatly improving sampling efficiency and reducing sampling difficulty, air can enter the xylem vessels at the moment of cutting, forming an air embolism that blocks the water transport channels, causing the leaves to dehydrate, wilt, or even dry out and fall off. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a cutting sampling device to prevent air embolism in plants. The technical problem this invention aims to solve is: how to cut plant branches in water to prevent air embolism.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A shearing sampling device for preventing air embolism in plants includes a wired control chassis and a sampling frame fixed on the chassis. A support rod is fixed on the sampling frame, and an adjustment rod is slidably connected to the support rod. An electric hydraulic clamp is fixed on the adjustment rod. The sampling frame has an immersion chamber, and a mesh box is placed inside the immersion chamber. A first adjustment component for controlling the height of the mesh box is installed inside the sampling frame, and a second adjustment component for controlling the height of the adjustment rod is installed inside the support rod. An inlet is opened on the mesh box, and a guide groove is opened inside the sampling frame. A guide slide is slidably connected to the guide groove, and an electric pruning shear is fixed on the guide slide. The cutting part of the electric pruning shear passes through the inlet and enters the mesh box.

[0008] The working principle of this invention is as follows: The height of the electric hydraulic clamp can be controlled by the second regulating component, thereby clamping and fixing branches of different lengths to improve the overall sampling efficiency and effect. Since air enters the xylem vessels at the moment of cutting, forming an air embolism and blocking the water transport channel, soaking can allow the cut to reabsorb water, dissolve and expel the air bubbles, and restore the unobstructed flow of the vessels. Therefore, an electric pruning shear is installed in the water tank, and the bottom of the branch is inserted into the water tank. The electric pruning shear is used to cut the branch into sections in the water tank to isolate the air environment. After soaking is completed, the electric pruning shear is retracted, and the net box can be raised by the first regulating component to remove the soaked branch from the soaking chamber, which is convenient for personnel to carry out subsequent sampling and testing operations.

[0009] A servo motor is fixed inside the sampling frame. A winding wheel is coaxially fixed on the output shaft of the servo motor. A traction rope is fixed on the winding wheel, and one end of the traction rope is fixedly connected to a guide slide.

[0010] With the above structure, a servo motor can drive the winding wheel to rotate. After the winding wheel rotates, it will wind up the traction rope, which will then further pull the guide slide to move, thereby achieving the retraction effect of the electric pruning shears and ensuring that it does not affect the normal lifting of the cage.

[0011] A return spring is fixed between the guide slide and the groove wall of the guide slide.

[0012] With the above structure, the return spring can push the guide rail slide back when the winding wheel releases the traction rope, thereby further resetting the electric pruning shears and completing the normal pruning work.

[0013] The control component includes a control screw rotatably connected inside the sampling frame and a servo motor fixed inside the sampling frame. The output shaft of the servo motor is coaxially and fixedly connected to the control screw. A push rod is threaded onto the control screw, and the top end of the push rod is fixedly connected to the mesh box.

[0014] Using the above structure, a servo motor drives a control screw to rotate, which in turn drives a push rod to adjust the height. The push rod then transmits this height adjustment to the net cage, allowing the net cage to be adjusted in height. This enables the soaked branches to be removed from the soaking chamber, facilitating subsequent sampling and testing operations.

[0015] The second control component includes a second control screw rotatably connected inside the support rod and a second servo motor fixed inside the support rod. The output shaft of the second servo motor is coaxially fixedly connected to the second control screw, and the second control screw is threadedly connected to the control rod.

[0016] With the above structure, the second control screw can be rotated by the second servo motor. After the second control screw rotates, it will drive the control rod to move. After the control rod moves, it will control the height position of the electric hydraulic clamp.

[0017] Compared with existing technologies, this shear sampling device for preventing air embolism in plants has the following advantages:

[0018] 1. The height of the electric hydraulic clamp is controlled by the control component two, thereby clamping and fixing branches of different lengths, thus improving the overall sampling efficiency and effect.

[0019] 2. The cut branches are received through the soaking chamber. At the moment of cutting, air enters the xylem vessels and forms an air embolism, blocking the water transport channel. Soaking allows the cut to reabsorb water, dissolve and expel the air bubbles, and restore the smooth flow of the vessels. After soaking is completed, the net box can be raised by the control component to remove the soaked branches from the soaking chamber, which is convenient for subsequent sampling and testing operations.

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figures 1-3 As shown, a shearing sampling device for preventing air embolism in plants includes a wired control chassis 1, a sampling frame 2 fixed on the wired control chassis 1, a support rod 3 fixed on the sampling frame 2, an adjustment rod 4 slidably connected to the support rod 3, an electric hydraulic clamp 7 fixed on the adjustment rod 4, an immersion chamber 5 on the sampling frame 2, a net box 6 inside the immersion chamber 5, an adjustment component 1 for controlling the height of the net box 6 inside the sampling frame 2, an adjustment component 2 for controlling the height of the adjustment rod 4 inside the support rod 3, an inlet 17 on the net box 6, a guide groove 18 inside the sampling frame 2, a guide slide 19 slidably connected to the guide groove 18, an electric pruning shears 8 fixed on the guide slide 19, and the cutting part of the electric pruning shears 8 passing through the inlet 17 into the net box 6.

[0026] The working principle of this utility model is as follows: The height of the electric hydraulic clamp 7 can be controlled by the control component 2 to clamp and fix branches of different lengths, thereby improving the overall sampling efficiency and effect. Since air will enter the xylem vessels at the moment of cutting and form an air embolism, blocking the water transport channel, the cut can be soaked to allow the cut to reabsorb water, dissolve and expel the air bubbles, and restore the unobstructed flow of the vessels. Therefore, an electric pruning shear 8 is set in the water tank, and the bottom end of the branch is inserted into the water tank. The electric pruning shear 8 is used to cut the branch into sections in the water tank to isolate the air environment. After soaking is completed, the electric pruning shear 8 is controlled to retract, and the net box 6 can be raised by the control component 1 to remove the soaked branches from the soaking chamber 5, which is convenient for personnel to carry out subsequent sampling and testing operations.

[0027] A servo motor 13 is fixed inside the sampling frame 2. A winding wheel 10 is coaxially fixed on the output shaft of the servo motor 13. A traction rope 11 is fixed on the winding wheel 10. One end of the traction rope 11 is fixedly connected to the guide slide 19.

[0028] With the above structure, the servo motor 13 can drive the winding wheel 10 to rotate. After the winding wheel 10 rotates, it will wind up the traction rope 11. The winding rope will then further pull the guide slide 19 to move, thereby achieving the retraction effect of the electric pruning shears 8 so as not to affect the normal lifting operation of the net cage 6.

[0029] A return spring 20 is fixed between the guide slide 19 and the groove wall of the guide slide 18.

[0030] With the above structure, the return spring 20 can push the guide rail slide back to move when the winding wheel 10 releases the traction rope 11, thereby further resetting the electric pruning shears 8 and completing the normal pruning work.

[0031] The control component includes a control screw 12 rotatably connected in the sampling frame 2 and a servo motor 13 fixed in the sampling frame 2. The output shaft of the servo motor 13 is coaxially fixedly connected to the control screw 12. A push rod 14 is threadedly connected to the control screw 12, and the top end of the push rod 14 is fixedly connected to the mesh box 6.

[0032] Using the above structure, the servo motor 13 drives the control screw 12 to rotate, and the control screw 12 drives the push rod 14 to adjust the height. The push rod 14 further transmits this height adjustment action to the net box 6, so that the net box 6 can be adjusted in height, and the soaked branches can be taken out from the soaking chamber 5, which is convenient for personnel to carry out subsequent sampling and testing operations.

[0033] The second control component includes a second control screw 15 rotatably connected in the support rod 3 and a second servo motor 16 fixed in the support rod 3. The output shaft of the second servo motor 16 is coaxially fixedly connected to the second control screw 15, and the second control screw 15 is threadedly connected to the control rod 4.

[0034] With the above structure, the control screw 15 can be rotated by the servo motor 16. After the control screw 15 rotates, it will drive the control rod 4 to move. After the control rod 4 moves, it will control the height position of the electric hydraulic clamp 7.

[0035] The working principle of this utility model is as follows: A servo motor 16 drives a control screw 15 to rotate. The rotation of the control screw 15 moves the control rod 4, which in turn controls the height of the electric hydraulic clamp 7. This clamps and fixes branches of different lengths, allowing the bottom of the branches to penetrate the water tank. Electric pruning shears 8 then cut the branches into sections inside the tank, isolating them from the air environment. After soaking, a servo motor 13 drives a winding wheel 10 to rotate. This wind-up wheel 10 winds up the traction rope 11, which in turn pulls the guide slide 19, thus retracting the electric pruning shears 8 and ensuring it doesn't interfere with the normal lifting of the net box 6. The servo motor 13 also drives a control screw 12 to rotate, which in turn drives a push rod 14 for height adjustment. The push rod 14 then transmits this height adjustment to the net box 6, allowing the soaked branches to be removed from the soaking chamber 5 for subsequent sampling and testing.

[0036] In summary, by controlling the height of the electric hydraulic clamp 7 using the second control component, branches of different lengths can be clamped and fixed, thereby improving the overall sampling efficiency and effectiveness. Furthermore, since air can enter the xylem vessels during cutting, forming an air embolism and blocking the water transport channel, soaking allows the cut to reabsorb water, dissolve and expel the air bubbles, restoring the flow of water through the vessels. Therefore, an electric pruning shears 8 is installed inside the water tank, with the bottom of the branch inserted into the tank. The electric pruning shears 8 cut the branch into sections inside the tank, effectively isolating it from the air environment. After soaking, the electric pruning shears 8 are retracted, and the net box 6 can be raised using the first control component to remove the soaked branch from the soaking chamber 5, facilitating subsequent sampling and testing operations.
