Description

Technical Field

[0001] This invention relates to the field of sampling device technology, and specifically to a sampling device for leaf testing. Background Technology

[0002] When using existing plant leaf sampling devices, the purpose of the sampling device is to extract the required tissue or liquid sample from the plant leaf. However, the existing sampling device cannot observe the amount of liquid extracted or whether there are impurities in the liquid, thus affecting the accuracy of the sampling.

[0003] To address the aforementioned problems, Chinese Patent Publication No. CN223664333U discloses a sampling device for plant extraction, comprising a sampling tube with a needle connected to its bottom end, an observation window on the surface of the sampling tube, and a plunger inserted into the top end of the sampling tube. This device inserts the sampling tube, connected to the needle, into the rootstock of a plant, and then pulls a control ring to move the plunger and sealing gasket simultaneously, thereby extracting liquid from the plant rootstock using the sampling tube. The process involves drawing liquid into a sampling tube and observing it in real time through an observation window on the surface of the tube. This allows for the inspection of the liquid for impurities, thus enabling the sampling of plants without the inability to observe the amount of liquid drawn or whether there are impurities inside the liquid, which would affect the accuracy of the sampling.

[0004] The above-mentioned device has the following problems in actual use: Although the device can observe whether there are impurities inside the liquid, the impurities are still trapped inside the liquid and cannot be filtered out. As a result, the impurities reduce the accuracy of the detection and cause errors in the detection results, that is, the detection is inaccurate. Summary of the Invention

[0005] This invention provides a sampling device for leaf inspection, which solves the problem that existing sampling devices cannot remove impurities retained on the leaves during sampling and inspection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sampling device for blade inspection, comprising a sampling box with a top opening, and a sampling mechanism disposed within the sampling box; the sampling mechanism comprises a sampling block, a moving block, a plate, a plurality of cleaning components equidistantly arranged along the length direction of the moving block, a sampling groove on the sampling block, a side hole on the sampling groove, and a driving component for driving the moving block to reciprocate along the width direction of the sampling block; the sampling block is fixedly connected to the sampling box; the moving block is slidably connected to the side hole; the plate is slidably connected to the sampling groove; the cleaning component comprises a cleaning block, a frosting block, and a groove on the cleaning block; the cleaning block is fixedly connected to the moving block; the frosting block is connected to the groove.

[0007] The principles and advantages of this scheme are: The blades are placed on the cleaning block, and then a worker pushes the plate, clamping the blades together with the cleaning block. A moving block then drives the cleaning block in a reciprocating motion. During this motion, the cleaning block moves relative to the blades, allowing it to remove impurities adhering to the blades and reduce the amount of impurities on the blades.

[0008] Because there is a gap between the two cleaning blocks, the impurities removed from the blade fall to the bottom of the sampling block, thus separating the impurities from the blade and making full preparations for the blade inspection operation.

[0009] The abrasive blocks are placed during the cleaning block's movement to increase the friction between the cleaning block and the blades. This allows the cleaning block to more thoroughly and completely clean the impurities on the blades, thus enhancing the cleaning effect.

[0010] Furthermore, the cleaning component also includes an extension; the extension includes a guide rod, a guide groove on the groove, and a power unit for driving the guide rod to perform vertical reciprocating motion; the guide rod is slidably connected to the guide groove; and the abrasive block is fixedly connected to the guide rod.

[0011] The guide rod drives the abrasive block to make vertical reciprocating motion, thereby improving the fit between the abrasive block and the blade. This allows the abrasive block to remove impurities from the blade more efficiently and comprehensively, thus further enhancing the working effect of the abrasive block.

[0012] Furthermore, it also includes auxiliary components; the auxiliary components include a movable block, an auxiliary hole on the sampling slot, a plurality of auxiliary parts equidistantly arranged along the length direction of the movable block, and a motion unit for driving the movable block to reciprocate along the length direction of the auxiliary hole; the auxiliary parts include an auxiliary block, an auxiliary plate, a plurality of sponge brushes equidistantly arranged along the length direction of the auxiliary plate, and an auxiliary groove on the auxiliary block; the cleaning block has a through hole; the auxiliary block is slidably connected to the through hole; the auxiliary block passes through the auxiliary hole and is fixedly connected to the movable block; the auxiliary plate is connected to the auxiliary groove; and the sponge brushes are fixedly connected to the auxiliary plate.

[0013] By arranging several auxiliary blocks perpendicularly to the cleaning block, the auxiliary blocks and the cleaning block are connected to form a mesh. The formation of the mesh expands the cleaning range of the blades, thus allowing impurities on the blades to be removed more thoroughly.

[0014] Because the auxiliary block can reciprocate relative to the length of the cleaning block, the cleaning range of the auxiliary block is expanded, making the impurities on the blades more efficiently removed under the action of the auxiliary block.

[0015] The sponge brush is used during the movement of the auxiliary block to absorb residual moisture on the leaves, thereby reducing the impact of moisture on leaf detection and improving the efficiency and quality of leaf detection.

[0016] Furthermore, the auxiliary part also includes an auxiliary unit; the auxiliary unit includes an auxiliary rod, a guide block, a push block, a first spring, and a moving part for driving the push block to perform vertical reciprocating motion; the auxiliary rod and the guide block are both fixedly connected to the auxiliary groove; the auxiliary plate is hinged to the auxiliary rod; the push block is slidably connected to the guide block, and the push block abuts against the auxiliary plate; the two ends of the first spring are respectively connected to the auxiliary plate and the auxiliary groove.

[0017] The vertical reciprocating motion of the pusher causes the auxiliary plate to swing back and forth. During the swinging motion of the auxiliary plate, the force of the sponge brush is increased, and the effective range of the sponge brush is expanded, allowing the sponge brush to more completely absorb the moisture on the blades, thus enhancing the effect of the sponge brush.

[0018] Furthermore, it also includes a linkage assembly; the linkage assembly includes a piston cylinder, a piston block, a linkage pipe, an air pipe, a connecting block, and an air duct opened on the sampling slot; the piston cylinder is fixedly connected to the outer wall of the sampling block; the piston block is slidably connected to the piston cylinder; the linkage pipe and the air pipe are both connected to the piston cylinder; the air pipe is connected to the air duct; and the two ends of the connecting block are fixedly connected to the piston block and the moving block, respectively.

[0019] With the combined action of the piston block and piston cylinder, a forceful airflow can be blown into the air duct. As the airflow exits through the air duct, it further loosens any loose impurities on the blades, allowing them to be removed more thoroughly by the airflow and ultimately fall to the bottom of the sampling block, thus further reducing the amount of impurities adhering to the blades.

[0020] Furthermore, the linkage component also includes a connecting groove on the air duct and several air plates equidistantly arranged along the length of the connecting groove; the connecting groove communicates with the side hole; the air plates are fixedly connected to the cleaning block, and the air plates pass through the connecting groove and extend into the air inlet duct.

[0021] The purpose of the air deflector is to adjust the pressure at different locations in the air duct through its reciprocating motion, thereby creating pressure variations in the airflow as it passes through the duct. Therefore, under these pressure variations, the airflow can locally increase its discharge pressure, allowing it to more effectively clean the blades and thus enhancing its overall effect.

[0022] Furthermore, a cleaning brush is fixedly attached to the air panel.

[0023] During the movement of the air deflector, the cleaning brush reduces the amount of impurities adhering to the air outlet of the air duct, thereby reducing the probability of blockage at the air outlet and allowing the airflow to be discharged efficiently through the outlet, thus ensuring the quality of the airflow discharge.

[0024] Furthermore, the power unit includes a wall block, a movable block, a second spring, and a power component for driving the movable block to reciprocate vertically; the outer wall of the wall block is fixedly connected to the auxiliary block; the movable block is slidably connected to the wall block, and the movable block abuts against the abrasive block; the two ends of the second spring are respectively connected to the guide rod and the guide groove.

[0025] During the vertical reciprocating motion of the movable block, the abrasive block can perform vertical reciprocating motion under the combined action of the movable block and the second spring.

[0026] Furthermore, it also includes a pushing unit; the pushing unit includes a recess, a driving block, and a driving component for driving the driving block to reciprocate along the length direction of the recess; the recess is fixedly connected to the sampling box; the driving block is slidably connected to the recess, and the driving block abuts against the auxiliary block; the motion unit is a third spring; the two ends of the third spring are respectively connected to the auxiliary block and the through hole.

[0027] During the movement of the driving block, the auxiliary block, under the combined action of the driving block and the third spring, can reciprocate along the length of the through hole.

[0028] Furthermore, the moving parts include a motion shaft, a first gear, a first rack, a cam, a fourth spring, a first bottom hole in the auxiliary groove, and a second bottom hole in the through hole; the motion shaft is rotatably connected to the auxiliary groove; the first bottom hole communicates with the second bottom hole; the first gear and the cam are both located in the first bottom hole and are fixedly connected to the motion shaft; the first rack is fixedly connected to the outer wall of the bottom of the cleaning block, and the first gear meshes with the first rack; the cam abuts against the push block; the two ends of the fourth spring are respectively connected to the push block and the guide block.

[0029] During the movement of the auxiliary block, the first gear meshes with the first rack, thereby driving the motion shaft to rotate. During the rotation of the motion shaft, the cam rotates synchronously. During cam rotation, when the cam's protrusion abuts against the push block, the push block moves vertically upward, compressing the fourth spring; when the cam's protrusion no longer abuts against the push block, the push block returns to its original position under the action of the fourth spring, moving vertically downward. Therefore, the push block can perform vertical reciprocating motion. Attached Figure Description

[0049] The power unit also includes guide holes symmetrically opened on both sides of the auxiliary groove along the length direction of the auxiliary groove; it also includes a linkage component; the linkage component includes a fixed block 27 and several arc-shaped grooves opened on the fixed block 27 along the length direction of the fixed block 27; the fixed block 27 is located in the guide hole and is fixedly connected to the through hole 32; the power component includes an arc-shaped wedge, a fifth spring, and a wall groove opened on the wall block 33; the arc-shaped wedge is fixedly connected to the movable block 34, the arc-shaped wedge is located in the arc groove, and the arc-shaped end of the arc-shaped wedge is in contact with the bottom of the arc groove; the fifth spring is located in the wall groove, and the two ends of the fifth spring are respectively connected to the wall block 33 and the wall groove.

[0050] The driving component includes a drive shaft 28, a second gear 29, and a third gear 30; the drive shaft 28 is rotatably connected to the outer wall of the sampling box 1; the second gear 29 and the third gear 30 are both fixedly connected to the drive shaft 28; the moving block 3 is a second rack, which meshes with the second gear 29; the driving block 23 is a third rack, which meshes with the third gear 30.

[0051] Specific implementation process: Remove the plate 4 using the handle 6, then place the blade on the cleaning block 7. Subsequently, make the plate 4 move vertically downward in the sampling slot, so that the blade is clamped by the action of the cleaning block 7 and the plate 4.

[0052] After the blade is clamped, cylinder 26 is activated, and the output shaft of cylinder 26 drives the connecting block to reciprocate along the length of the side hole 5. During the movement of the connecting block, the connecting block drives the cleaning block 7 to move synchronously through the second rack. During the movement of the cleaning block 7, the cleaning block 7 will move relative to the blade, so that the cleaning block 7 can remove the impurities adhering to the blade, thereby reducing the amount of impurities adhering to the blade.

[0053] Because there is a gap between the two cleaning blocks 7, the impurities removed from the blade will fall to the bottom of the sampling block 2, thereby separating the impurities from the blade and making full preparations for the blade inspection operation.

[0054] During the movement of cleaning block 7, the abrasive block 8 is set to increase the friction between cleaning block 7 and the blade, so that cleaning block 7, with the assistance of abrasive block 8, can more fully and completely clean the impurities on the blade, thus enhancing the cleaning effect on the blade impurities.

[0055] During the movement of the second rack, the second rack meshes with the second gear 29, thereby driving the drive shaft 28 to rotate. During the rotation of the drive shaft 28, the third gear 30 rotates synchronously. During the rotation of the third gear 30, the third gear 30 meshes with the third rack, enabling the third rack to reciprocate along the length of the recess 22. During the movement of the third rack, when the third rack approaches and abuts against the auxiliary block 11, the auxiliary block 11 moves away from the air duct 19, and the third spring is compressed; when the third rack moves away from and abuts against the auxiliary block 11, the auxiliary block 11 resets under the action of the third spring, and moves towards the air duct 19. Therefore, the auxiliary block 11 can reciprocate relative to the through hole 32.

[0056] By vertically arranging several auxiliary blocks 11 relative to the cleaning block 7, the connection between the auxiliary blocks 11 and the cleaning block 7 forms a mesh block. The formation of the mesh block expands the cleaning range of the blades, thereby allowing impurities on the blades to be removed more thoroughly.

[0057] During the movement of auxiliary block 11, the arc-shaped wedge moves synchronously. During the movement of the arc-shaped wedge, the movable block 34 is able to perform vertical reciprocating motion under the combined action of the arc-shaped wedge and the fifth spring.

[0058] During the movement of the movable block 34, the abrasive block 8 can perform vertical reciprocating motion under the combined action of the movable block 34 and the second spring.

[0059] The vertical reciprocating motion of the abrasive block 8 improves the adhesion between the abrasive block 8 and the blade, enabling the abrasive block 8 to remove impurities from the blade more efficiently and comprehensively, thus further enhancing the working effect of the abrasive block 8.

[0060] Because the auxiliary block 11 can reciprocate relative to the length direction of the cleaning block 7, the cleaning range of the auxiliary block 11 is expanded, making the impurities on the blades more efficiently removed under the action of the auxiliary block 11.

[0061] During the movement of the auxiliary block 11, the sponge brush 13 is set up to absorb the residual moisture on the blade, thereby reducing the impact of moisture on the blade detection, which improves the efficiency and quality of the blade detection.

[0062] During the movement of auxiliary block 11, the first gear 24 meshes with the first rack, thereby driving the motion shaft to rotate. During the rotation of the motion shaft, cam 25 rotates synchronously. During the rotation of cam 25, when the protrusion of cam 25 abuts against push block 16, push block 16 moves vertically upward, compressing the fourth spring; when the protrusion of cam 25 no longer abuts against push block 16, push block 16 returns to its original position under the action of the fourth spring, and push block 16 moves vertically downward. Therefore, push block 16 can perform vertical reciprocating motion.

[0063] The vertical reciprocating motion of the pusher 16 causes the auxiliary plate 12 to swing back and forth. During the swinging motion of the auxiliary plate 12, the force of the sponge brush 13 is increased, and the range of action of the sponge brush 13 is expanded, thereby enabling the sponge brush 13 to more completely absorb the moisture on the blades, thus enhancing the effect of the sponge brush 13.

[0064] During the movement of the connecting block, the piston block 18 moves synchronously. During the movement of the piston block 18, through the joint action of the piston block 18 and the piston cylinder 17, an airflow with a certain force can be blown into the air duct 19. As the airflow exits through the air duct 19, it can further loosen the loose impurities on the blades, thereby making the impurities more thoroughly removed under the action of the airflow, and finally falling to the bottom of the sampling block 2, thus further reducing the amount of impurities adhering to the blades.

[0065] The purpose of the air deflector 20 is to adjust the pressure discharged from different positions of the air duct 19 through its reciprocating motion, thereby causing pressure variations in the airflow at different locations along the air duct 19. Therefore, under these pressure variations, the airflow can locally increase its discharge pressure, allowing it to more effectively clean the blades and thus further enhancing its effectiveness.

[0066] During the movement of the air deflector 20, the cleaning brush 21 reduces the amount of impurities adhering to the air outlet of the air duct 19, thereby reducing the probability of blockage at the air outlet of the air duct 19 and enabling the airflow to be discharged efficiently through the air outlet, thus ensuring the quality of the airflow discharge.

[0067] In summary, by thoroughly removing impurities and moisture from the leaves, sufficient preparation is made for subsequent leaf inspection operations, thus comprehensively improving the quality and efficiency of leaf inspection.
