Description

Technical Field

[0001] This invention relates to the field of intelligent testing equipment technology, and in particular to a non-destructive testing device and method suitable for tree seedling testing. Background Technology

[0002] Before planting saplings, it is necessary to test and classify their diameter, height, and growth status in order to plan the required site and level of care for planting in advance. This will prevent poorly developed saplings from not receiving enough care after planting and thus failing to survive. However, since the number of saplings to be tested is large, manual testing is not only time-consuming, labor-intensive, and inefficient, but also prone to significant errors.

[0003] Chinese utility model patent with announcement number CN211121078U discloses a seedling diameter measuring device. This utility model uses a track to move at a constant speed over planted seedlings and infers the diameter of the seedlings by measuring the time the trees block the laser signal and combining the moving speed of the device, which is convenient for detecting rows of seedlings.

[0004] Although this invention solves the problem of low efficiency in manual inspection, the inspection part is easily blocked by the dense canopy of the saplings during inspection, and it can only inspect relatively vertical saplings. If a sapling is tilted, it cannot be effectively inspected.

[0005] Based on this, the present invention provides a non-destructive testing device and method suitable for seedling testing. Summary of the Invention

Detailed Implementation

[0048] The technical solution provided by the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] like Figures 1 to 29As shown, a non-destructive testing device and method suitable for seedling inspection includes a conveying mechanism 2, on which an alignment mechanism 1 and a testing mechanism 3 are movably mounted. A fixing mechanism 4 is rotatably mounted on the conveying mechanism 2. The conveying mechanism 2 includes a conveying frame 201, within which a transmission gear rod 204 is rotatably mounted. The transmission gear rod 204 is equipped with pulleys and is connected to the other transmission gear rods by a belt. A first transmission gear 207 is rotatably mounted on the conveying frame 201. A third motor 213 is fixedly mounted on the conveying frame 201. The output shaft of the third motor 213 is equipped with the first transmission gear 207, which is equipped with pulleys and is connected to the other transmission gears by a belt. A fourth transmission gear 4 is slidably mounted on the conveying frame 201. A slider 205 is connected to a conveyor frame 201 by a compression spring. A connecting gear 206 is rotatably mounted on the slider 205. A conveyor belt 202 is rolled on a transmission gear rod 204. A second transmission gear 210 and a third transmission gear 214 are rotatably mounted inside the conveyor frame 201. A first gear ring 211 and a second gear ring 215 are rotatably mounted inside the conveyor frame 201. The gears between the second transmission gear 210, the first gear ring 211, and the transmission gear rod 204 mesh to form a planetary gear structure. The gears between the third transmission gear 214, the second gear ring 215, and the transmission gear rod 204 mesh to form a planetary gear structure. A first limiting belt 209 is slidably mounted inside the conveyor frame 201. 09 is fixedly connected to the conveyor belt 202. Multiple first ratchet rods 212 are fixedly mounted on the first limiting belt 209. Limiting rods 203 are rotatably mounted on the first ratchet rods 212. The limiting rods 203 are used to evenly arrange and transport the seedlings to be inspected onto the conveyor belt 202. The limiting rods 203 have gear patterns that mesh with gears on the first gear ring 211 and the second gear ring 215. A pawl is installed inside the limiting rod 203, and the pawl inside the limiting rod 203 engages with the ratchet of the first ratchet rod 212. By starting the third motor 213, two first transmission gears 207 are driven to rotate. When the first slider 205 is pressed down, the connecting gear 206 meshes with the gears on the first transmission gears 207 and the transmission gear rod 204, and through the first transmission gear 206... 07 drives the transmission gear rod 204 to rotate, which in turn causes the conveyor belt 202 to roll. Simultaneously, through the planetary gear structure composed of the transmission gear rod 204, the second transmission gear 210, and the first gear ring 211, the first gear ring 211 rotates in the same direction, with its rotational speed slower than that of the transmission gear rod 204. Simultaneously, through the planetary gear structure composed of the transmission gear rod 204, the third transmission gear 214, and the second gear ring 215, the second gear ring 215 rotates in the same direction, with its rotational speed faster than that of the transmission gear rod 204. Through the first gear ring 211 and the second gear ring 215, the limiting rod 203 rotates on the first limiting belt 209.The saplings are evenly arranged and transported to the fixed mechanism 4 for subsequent testing.

[0050] like Figures 1 to 29 As shown, a second motor 208 is fixedly mounted on the conveyor frame 201. The second motor 208 is equipped with gears. A fixing mechanism 4 is rotatably mounted on the conveyor frame 201. The fixing mechanism 4 includes a fifth screw 403, on which a gear meshes with the gear on the second motor 208. A second slider 402 is mounted on the lead screw of the fifth screw 403. An electric push rod 404 is hinged to the second slider 402. A carrier plate 401 is hinged to the electric push rod 404. The carrier plate 401 contacts and engages with the first slider 205, pressing the first slider 205 down. This causes the connecting gear 206 to engage with the first transmission gear 207 and the gear on the transmission gear rod 204. The carrier plate 401 is rotatably mounted on the second transmission gear 210. The second motor 208 drives the fifth screw 403 to rotate, causing the second slider 402 to slide on the fifth screw 403. At the same time, the electric push rod 404 controls the carrier plate 401 to rotate on the conveyor frame 201, so that the seedlings on the carrier plate 401 can be rotated to the required angle for inspection. Meanwhile, the carrier plate 401 no longer drives the first slider 205 to press down, so that the connecting gear 206 no longer meshes with the gears on the first transmission gear 207 and the transmission gear rod 204, so that the transmission gear rod 204 no longer rotates, preventing too many seedlings from accumulating on the conveyor belt 202 during inspection.

[0051] like Figures 1 to 29As shown, a gripper 406 and a third slider 407 are slidably mounted inside the carrier plate 401. A compression spring is installed between the third slider 407 and the carrier plate 401. A cylindrical key is fixedly mounted on the gripper 406. A second limiting band 405 is hinged to the gripper 406. A tension spring is installed between the second limiting band 405 and the carrier plate 401. The second limiting band 405 is used to prevent the sapling from slipping off the carrier plate 401 when the carrier plate 401 is turned over. The third slider 407 has a sliding groove and gear patterns. The cylindrical key on the gripper 406 slides in conjunction with the sliding groove on the third slider 407. A fifth transmission gear 408 is rotatably mounted inside the carrier plate 401. The gear meshes with the fifth transmission gear 408. A first connecting rod 409 is fixedly mounted on the third slider 407. A second connecting rod 410 is slidably mounted inside the first connecting rod 409. A tension spring is installed between the second connecting rod 410 and the first connecting rod 409. A second limiting pawl 417 is fixedly mounted on the third slider 407. A limiting groove 411 is fixedly mounted inside the carrier plate 401. A first limiting pawl 416 is rotatably mounted inside the limiting groove 411. A cylindrical key is fixedly mounted on the first limiting pawl 416. A limiting plate 415 is slidably mounted inside the limiting groove 411. The limiting plate 415 has a wavy groove. The cylindrical key on the first limiting pawl 416 slides in conjunction with the groove on the limiting plate 415. The second limiting pawl 417 engages with the first limiting pawl 416. A fourth slider 412 is fixedly mounted on the limiting plate 415 and slidably mounted inside the carrier plate 401. The fourth slider 412 has gear patterns. A sixth transmission gear 414 is rotatably mounted inside the carrier plate 401. The gear patterns on the fourth slider 412 mesh with the sixth transmission gear 414. A third connecting rod 413 is fixedly mounted on the fourth slider 412. A compression spring is installed between the third connecting rod 413 and the carrier plate 401. When the seedling to be tested is transported to the carrier plate 401 via the limiting rod 203, the limiting rod 203 contacts the second connecting rod 410 and drives the second connecting rod 410 to move on the carrier plate 401. The sapling slides inward. Through the tension spring between the second link 410 and the first link 409, the first link 409 slides within the carrier plate 401. The first link 409 drives the third slider 407 to slide within the carrier plate 401, and causes the gripper 406 to slide and clamp the sapling on the carrier plate 401. At the same time, the first limiting pawl 416 and the second limiting pawl 417 cooperate to keep the gripper 406 in a clamped state. The diameter of the sapling to be tested is calculated based on the distance the third slider 407 slides within the carrier plate 401. Then, the second motor 208 and the electric push rod 404 are started to rotate the carrier plate 401 on the transport frame 201, flipping the sapling to a vertical angle for subsequent testing.

[0052] like Figures 1 to 29As shown, a marking mechanism 5 is fixedly installed inside the fixing mechanism 4, including a marking frame 501. The marking frame 501 is fixedly installed on the carrier plate 401. A ninth motor 506 is fixedly installed on the marking frame 501. A gear is mounted on the ninth motor 506. A second ratchet rod 504 with two ratchet teeth in opposite directions is rotatably installed inside the marking frame 501. The second ratchet rod 504 is provided with a triangular key. A hollow gear 505 is rotatably installed on the second ratchet rod 504. The hollow gear 505 meshes with the gear on the ninth motor 506. A pawl is installed inside the hollow gear 505 and engages with the ratchet of the second ratchet rod 504. A marking push plate 503 is slidably installed on the second ratchet rod 504. A triangular key is provided inside the marking push plate 503. The triangular key inside the marking push plate 503 slidably engages with the triangular key on the hollow gear 505. A marking push plate 503 is slidably installed on the marking push plate 503. A marking plate 502 is provided, and a compression spring is installed between the marking plate 502 and the marking push plate 503. The marking plate 502 is used to mark the seedlings after the test, so as to distinguish whether the data of the seedlings meet the standards after the test, and to facilitate subsequent individual maintenance. In use, the ninth motor 506 rotates to drive the hollow gear 505 to rotate, and drives one of the second ratchet rods 504 to rotate through the pawl. When the second ratchet rod 504 rotates, the inclined surface on the triangular key drives the marking push plate 503 to slide in the marking frame 501, and drives the marking plate 502 to slide on the marking frame 501 to mark the seedlings on the carrier plate 401. When the second ratchet rod 504 rotates to a certain angle, the inclined surface of the triangular key on the marking push plate 503 and the second ratchet rod 504 no longer contacts, so that the marking push plate 503 falls back to its original position, completing the marking of the seedlings.

[0053] like Figures 1 to 29As shown, the testing mechanism 3 includes a reference platform 301, a seventh motor 313, and a fourth screw 314. The reference platform 301 is slidably mounted on the transport frame 201. The seventh motor 313 is fixedly mounted on the transport frame 201 and is equipped with a pulley. The fourth screw 314 is rotatably mounted on the transport frame 201 and is equipped with a pulley. The fourth screws 314 are connected by a belt. The seventh motor 313 and the fourth screw 314 are also connected by a belt. The fourth screw 314 engages with the lead screw of the reference platform 301. An eighth motor 315 is fixedly mounted on the reference platform 301 and is equipped with a pulley. The reference platform 301 rotates internally... A sixth screw 316 is mounted on the rotating part, and a pulley is installed on the sixth screw 316. The sixth screw 316 is connected to the eighth motor 315 via a belt. A lifting rod 302 is slidably installed inside the reference platform 301. The lifting rod 302 cooperates with the lead screw of the sixth screw 316. A detection rod 303 is fixedly installed on the lifting rod 302. The distance between the detection rod 303 and the reference platform 301 is adjusted by the lifting rod 302 to detect the height of the seedling. At the same time, the seventh motor 313 drives the fourth screw 314 to rotate, controlling the reference platform 301 to slide on the transport frame 201, so that the reference platform 301 fits against the bottom of the seedling being tested, making the test data more accurate.

[0054] like Figures 1 to 29As shown, a fourth motor 304 is fixedly mounted on the detection rod 303, and a gear is mounted on the fourth motor 304. A second screw 305 is rotatably mounted on the detection rod 303, and a gear is mounted on the second screw 305. The gear on the second screw 305 meshes with the gear on the fourth motor 304. A detection push rod 306 is slidably mounted on the detection rod 303, and the detection push rod 306 cooperates with the lead screw of the second screw 305. A second width detection rod 312 is rotatably mounted on the detection push rod 306, and the second width detection rod 312 has gear patterns. A sixth motor 310 is fixedly mounted on rod 306, and a gear is mounted on the sixth motor 310. A third screw 311 is rotatably mounted on the detection push rod 306, and a gear is mounted on the third screw 311. The gear on the sixth motor 310 meshes with the gear on the third screw 311. The third screw 311 engages with the gear-patterned worm gear on the second width detection rod 312. A fifth motor 309 is fixedly mounted on detection rod 303, and a fourth transmission gear 308 is rotatably mounted on detection rod 303. The fifth motor 309 is equipped with a gear and engages with the fourth transmission gear. Gear 308 meshes, and a first width detection rod 307 is slidably installed inside the detection rod 303. The first width detection rod 307 has gear patterns that mesh with the fourth transmission gear 308. The first width detection rod 307 and the second width detection rod 312 are used to detect the width of the sapling crown. By starting the sixth motor 310, the third screw 311 is driven to rotate. The rotation of the third screw 311 drives the second width detection rod 312 to rotate on the detection push rod 306, flipping the second width detection rod 312 to a vertical angle. Then, the fourth motor 30... 4. Drive the second screw 305 to rotate on the detection rod 303, and drive the detection push rod 306 to slide on the detection rod 303. Adjust the distance between the second width detection rod 312 and the lifting rod 302 so that the lifting rod 302 and the second width detection rod 312 are in contact with the two sides of the tree crown to detect its width. At the same time, by starting the fifth motor 309, drive the first width detection rod 307 to slide on the detection rod 303 so that the first width detection rod 307 is in contact with the two sides of the tree crown to detect its width. Calculate the size of the seedling crown based on the width in both directions.

[0055] like Figures 1 to 29 As shown, the alignment mechanism 1 includes a push plate 101, which is slidably mounted on the transport frame 201. The alignment mechanism 1 includes a first screw 102 and a first motor 103. The first screw 102 is rotatably mounted on the transport frame 201 and is equipped with gears. The first motor 103 is fixedly mounted on the transport frame 201 and is equipped with gears. The gears on the first motor 103 mesh with the gears on the first screw 102. The first motor 103 drives the first screw 102 to rotate, and the rotation of the first screw 102 drives the push plate 101 to slide on the transport frame 201. The push plate 101 pushes and arranges the bottom of the seedlings on the transport mechanism 2 neatly, making it easier for the detection mechanism 3 to perform detection.

[0056] Working Principle: During operation, the sapling to be tested is first placed on the transport frame 201. Then, the third motor 213 is started, driving the first transmission gear 207 to rotate. Simultaneously, the transmission gear rod 204 drives the conveyor belt 202 to roll, and the conveyor belt 202 drives the first limit belt 209 to slide on the transport frame 201, causing the limit rod 203 to roll. The connecting gear 206 meshes with the gears on the first transmission gear 207 and the transmission gear rod 204, driving the transmission gear rod 204 to rotate. When the transmission gear rod 204 rotates, the second transmission gear 210 drives the first gear ring 211 to rotate in the same direction, making its speed slower than that of the transmission gear rod 204. Simultaneously, the third transmission gear 214 drives the second gear ring 215 to rotate in the same direction. The rotation speed is made faster than that of the transmission gear rod 204, which drives the limiting rod 203 to rotate on the first limiting belt 209. The limiting rod 203 evenly transports the seedlings on the transport frame 201 to the transport belt 202. At the same time, the first motor 103 is started to drive the push plate 101 to slide on the transport frame 201, pushing the bottom of the seedlings to align. When the seedlings are transported to the carrier plate 401 by the limiting rod 203, the limiting rod 203 contacts the second connecting rod 410 and drives the second connecting rod 410 to slide in the carrier plate 401. Through the tension spring between the second connecting rod 410 and the first connecting rod 409, the third slider 407 is driven to slide in the carrier plate 401. Through the third slider 407, the electric gripper 406 clamps the seedling to be detected and, through the first limiting pawl 416, the electric gripper 406 clamps the seedling to be detected. The second limiting pawl 417 engages to fix the position of the third slider 407, and the diameter of the seedling being tested is calculated based on the sliding distance of the third slider 407. Then, the second motor 208 is started to drive the fifth screw 403 to rotate, and at the same time, the electric actuator 404 is started to drive the carrier plate 401 to rotate on the transport frame 201, flipping the seedling to a vertical angle, and preventing it from sliding down by the second limiting belt 405. Then, the lifting rod 302 is started to adjust the height of the detection rod 303 to fit against the top of the seedling for height detection. At the same time, the fifth motor 309 is started to drive the first width detection rod 307 to slide against the detection rod 303, so that the first width detection rod 307 fits against both sides of the canopy to detect its width. At the same time, the fourth motor 304 is started to drive the second screw 305. The second screw 305 rotates, causing the detection push rod 306 to slide on the detection rod 303. Simultaneously, the sixth motor 310 is activated, causing the second width detection rod 312 to rotate on the detection push rod 306 to a vertical angle. This allows the lifting rod 302 to contact the second width detection rod 312 on both sides of the tree canopy to detect its width. The results of the detection are then classified. Afterward, the ninth motor 506 is activated, and its rotation is controlled to be forward or reverse according to the category. The ninth motor 506 drives the hollow gear 505 to rotate, which in turn drives one of the second ratchet rods 504 to rotate, causing the marking push plate 503 to rise and mark the seedling to complete the detection. Then, the second motor 208 is activated to rotate in the opposite direction, and the electric push rod 404 is retracted simultaneously.The carrier plate 401 rotates to its original position on the conveyor frame 201, and the carrier plate 401 drives the first slider 205 to press down, causing the connecting gear 206 to mesh with the gears on the first transmission gear 207 and the transmission gear rod 204, driving the transmission gear rod 204 to rotate. This rotation, via the limiting rod 203, contacts the third connecting rod 413, causing the third connecting rod 413 to slide within the carrier plate 401. This causes the limiting plate 415 to slide within the limiting groove 411, and via the wave-shaped groove on the limiting plate 415, the first limiting pawl 416 rotates a certain angle within the limiting groove 411, so that the first limiting pawl 416 no longer engages with the second limiting pawl 417. This causes the third slider 407 to return to its original position via the compression spring between it and the carrier plate 401, causing the gripper 406 to release its grip on the seedling, allowing the seedling to be transported via the limiting rod 203 onto the conveyor belt 202 for subsequent collection.
