Description

Technical Field

[0001] The present invention relates to the technical field of toothpick testing, and particularly relates to a toothpick testing method and device. Background Art

[0002] Traditional balers pick up forage through toothpicks installed on the pickup mounting crossbeam. Since the working environment of the baler is relatively complex and harsh, the failure rate of the toothpicks is relatively high and the toothpicks are vulnerable parts. When conducting various studies on the toothpicks, certain tests are required to verify. Currently, each manufacturer producing balers generally conducts field tests on the baler and regards the performance detection of the toothpicks as part of the test. The toothpicks are greatly restricted in such tests, and the cycle required for various tests of the toothpicks is relatively long. If only the toothpicks are separately subjected to field tests, the time, energy and other costs will be extremely high. Therefore, there is an urgent need for a device or method to test the toothpicks separately and at the same time reduce the time, energy and other costs for various performance tests of the toothpicks.

[0003] There is a kind of machine that tests the ultimate deformation by hitting the toothpick on the impact rod, and at the same time detects the number of times through an optoelectronic device, so as to achieve the purpose of testing the number of times the toothpick undergoes ultimate deformation. However, this machine has the following defects:

[0004] 1. The toothpick directly hits the impact rod. The impact rod is a slender rod, and it is difficult to simulate the phased planar contact between the toothpick and the ground in the actual working environment.

[0005] 2. The whole of this machine is a steel frame structure. By fixing the toothpick and hitting the toothpick by rotating the impact rod, it is impossible to simulate the wear condition of the toothpick end part by loose soil and sand in working environments such as sand and dry land. Moreover, when the toothpick breaks, it is easy to break and fly out, which will pose a life safety threat to the surrounding personnel.

[0006] 3. Such a method can only obtain the relationship between the ultimate deformation of the toothpick and the number of times of force application, but cannot measure the corresponding force condition of the toothpick. Such a test method has great limitations. Summary of the Invention

[0058] First Embodiment

[0059] This embodiment discloses a bullet tooth testing device, as Figure 1As shown, the bullet tooth testing device includes a mounting frame 1, a mounting beam roller 2, a retaining frame assembly 3, and a driver 41. The mounting frame 1 is formed by connecting multiple mounting cross beams 11 and multiple mounting longitudinal beams 12. Specifically, a part of the mounting cross beams 11 enclose a rectangular frame 13, and these mounting cross beams 11 are connected end to end in sequence. Similarly, another part of the mounting cross beams 11 enclose a rectangular frame 13, and these mounting cross beams 11 are connected end to end in sequence. The two rectangular frames 13 are arranged one above the other, and the four corners of the two rectangular frames 13 are respectively connected by the mounting longitudinal beams 12 to form the mounting frame 1.

[0060] As Figure 1 、 Figure 2 As shown, a mounting plate 14 is also provided on the mounting frame 1. Both ends of the mounting plate 14 in its length direction have holes. Correspondingly, the rectangular frame 13 at the bottom of the mounting frame 1 also has holes. The detachable connection between the mounting frame 1 and the mounting plate 14 is realized by passing bolts through the holes of the mounting plate 14 and the holes of the rectangular frame 13. There are two adjustment holes 15 on the mounting plate 14, and both adjustment holes 15 are waist-shaped holes. The length direction of the two adjustment holes 15 is the same as the length direction of the mounting plate 14. The detachable connection between the driver 41 and the mounting plate 14 is realized by passing bolts through the holes on the driver 41 and the two adjustment holes 15. Such a setting can flexibly adjust the position of the driver 41 on the mounting plate 14.

[0061] Optionally, the driver 41 can be a drive motor. Optionally, the driver 41 can be a drive motor with a speed reducer. The driver 41 can also be regarded as a drive module.

[0062] As Figure 1 、 Figure 3 As shown, two bearing seats 16 are provided on the top of the mounting frame 1, and the two bearing seats 16 are symmetrically arranged. The bearing seats 16 are detachably connected to the mounting frame 1 with bolts. The mounting beam roller 2 includes a mounting shaft 21 and a mounting member 22. Both ends of the mounting shaft 21 respectively pass through the two bearing seats 16, and the mounting shaft 21 is rotatably connected to the top of the mounting frame 1 through the bearing seats 16. At least one mounting member 22 is provided on the mounting shaft 21, and the length direction of the mounting member 22 is the same as the length direction of the mounting shaft 21. One side of the mounting member 22 in its length direction is connected to the mounting shaft 21, and one side of the mounting member 22 in its length direction is concavely formed with a mounting groove 23. The bottom of the mounting groove 23 has multiple mounting holes 24 arranged in sequence along the length direction of the mounting member 22, and the mounting holes 24 are used for mounting bullet teeth. Such a setting can mount the bullet teeth in the mounting groove 23, and can make the bullet teeth more stably arranged on the mounting beam roller 2. By respectively arranging multiple bullet teeth at multiple mounting holes 24, multiple bullet teeth can be tested simultaneously, increasing the number of tested bullet teeth to reduce errors.

[0063] Optionally, as Figure 3As shown, when the number of the mounting members 22 is multiple, the multiple mounting members 22 are uniformly arranged around the axis of the mounting shaft 21. Such a setting can test multiple groups of spring teeth with different specifications and models simultaneously, saving the test time.

[0064] As Figure 1 , Figure 3 , Figure 4 As shown, the driving end of the driver 41 and one end of the mounting shaft 21 are on the same side of the mounting frame 1. The driving end of the driver 41 is drivingly connected to one end of the mounting shaft 21 through a transmission assembly 5. One end of the mounting shaft 21 connected to the driver 41 can be regarded as the power input end of the mounting beam roller. The transmission assembly 5 includes a driving wheel 51, a driven wheel 52, and a transmission belt 53. The driving wheel 51 is arranged at the driving end of the driver 41, and the driving wheel 51 has a wheel groove 54. The driven wheel 52 is arranged at one end of the mounting shaft 21, and the driven wheel 52 has a wheel groove 54. One end of the transmission belt 53 is sleeved in the wheel groove 54 of the driving wheel 51, and the other end of the transmission belt 53 is sleeved in the wheel groove 54 of the driven wheel 52. By adjusting the position of the driver 41, the transmission belt 53 can be tightened to prevent the transmission belt 53 from falling off.

[0065] Optionally, as Figure 4 shown, the number of the transmission belts 53 is multiple. Correspondingly, the number of the wheel grooves 54 on the driving wheel 51 and the driven wheel 52 is the same as the number of the transmission belts 53. One ends of the multiple transmission belts 53 are respectively sleeved in the multiple wheel grooves 54 of the driving wheel 51, and the other ends of the multiple transmission belts 53 are respectively sleeved in the multiple wheel grooves 54 of the driven wheel 52. When one of the transmission belts 53 breaks, it still does not affect the transmission of the other transmission belts 53.

[0066] As Figure 5 shown, the retaining frame assembly 3 includes an adjustment frame 31, a fixing plate 32, and a nylon plate 33. The adjustment frame 31 adopts a frame structure composed of multiple first adjustment beams 311 and multiple second adjustment beams 313. The length of the second adjustment beam 313 is longer than that of the first adjustment beam 311. Among the two relatively arranged first adjustment beams 311, the fixing plate 32 is arranged on one first adjustment beam 311 and is located on the side of this first adjustment beam 311 close to the other first adjustment beam 311. The nylon plate 33 is installed on the fixing plate 32 with screws and is located on the side surface of the fixing plate 32 close to the other first adjustment beam 311, thus realizing the detachable connection between the nylon plate 33 and the fixing plate 32. The other first adjustment beam has multiple first waist-shaped holes 312. Among the two relatively arranged second adjustment beams 313, both second adjustment beams 313 have multiple second waist-shaped holes 314. The multiple second waist-shaped holes 314 on the two second adjustment beams 313 are symmetrically arranged.

[0067] As Figure 1 ,Figure 5 As shown, the blocking frame assembly 3 is arranged within the rectangular frame 13 located at the top of the mounting frame 1. The spring tooth testing device further includes a first bolt group and a second bolt group. Specifically, the first bolt group includes two first bolts 42. One end of each of the two first bolts 42 passes through the holes of the rectangular frame 13 and cooperates with the nuts at their ends to achieve the detachable connection of the first bolts 42 to the rectangular frame 13. The other ends of the two first bolts 42 respectively pass through two first waist-shaped holes 312 and cooperate with the nuts at their ends to achieve the detachable connection of the first bolts 42 to the adjustment frame 31 of the blocking frame assembly 3. The number of the second bolt groups is two, and the two second bolt groups are respectively arranged on both sides of the adjustment frame 31 along its length direction. Since the connection manners of the two bolt groups to the adjustment frame 31 are the same, one set of the second bolt group and the multiple second waist-shaped holes 314 on one side of the adjustment frame 31 are taken as an example for introduction. The second bolt group includes two second bolts 43. One end of each of the two second bolts 43 passes through the holes of the rectangular frame 13 and cooperates with the nuts at their ends to achieve the detachable connection of the second bolts 43 to the rectangular frame 13. The other ends of the two second bolts 43 respectively pass through two second waist-shaped holes 314 and cooperate with the nuts at their ends to achieve the detachable connection of the second bolts 43 to the adjustment frame 31 of the blocking frame assembly 3. Through the cooperation of the first bolt group and the second bolt group, the blocking frame assembly 3 can be movably connected to the top of the mounting frame 1, and the position of the blocking frame assembly 3 can also be flexibly adjusted through the cooperation of the first bolt group and the second bolt group. When the mounting beam roller 2 is arranged at the top of the mounting frame 1, the fixing plate 32 is located on one side of the mounting beam roller 2 along its length direction, and the nylon plate 33 is located on one side of the mounting beam roller 2 along its length direction. The adjustment frame 31 is movably connected to the top of the mounting frame 1 and is located below the mounting beam roller 2.

[0068] Optionally, as Figure 4 , Figure 6 , Figure 7 ​As shown in the figure, the bullet tooth test device further includes a simulation housing 61 and a shield 62. The simulation housing 61 has a receiving cavity 611 for placing simulation experiment materials, which include fine sand and gravel, soil and water. Placing the simulation experiment materials in the receiving cavity 611 can simulate the working scenario of the bullet teeth. The simulation housing 61 is installed on the top of the mounting rack 1, and the opening of the receiving cavity 611 of the simulation housing 61 is located directly below the mounting beam roller 2. When the bullet teeth are installed on the mounting beam roller 2, as the mounting beam roller 2 rotates, the bullet teeth also rotate and pass through the receiving cavity 611. By placing fine sand and gravel and some water in the receiving cavity 611, the working environment of a typical sandy land plot can be simulated, and the working life of the bullet teeth in this working environment can be measured in advance. Both ends of the shield 62 along its length direction have a notch 621, which facilitates the passing through of the mounting shaft 21 of the mounting beam roller 2 when the shield 62 covers the mounting beam roller 2. Optionally, by inserting the simulation housing 61 into the space of the shield 62, the shield 62 is fixedly engaged with the simulation housing 61. Optionally, one side of the shield 62 is hinged to the top of the mounting rack 1 or one side of the simulation housing 61, and the other side of the shield 62 is flipped to cover the mounting beam roller 2. When the bullet teeth break or pop out during the test, the shield 62 plays a protective role to prevent the broken bullet teeth from popping out and injuring the test personnel.

[0069] Optionally, both ends of the simulation housing 61 along its length direction have a notch 621, which facilitates the passing through of the mounting shaft 21 of the mounting beam roller 2.

[0070] Optionally, as Figure 1 , Figure 4 shown in the figure, the bullet tooth test device further includes an image sensor 44 and a controller 45. The image sensor 44 is arranged at the edge of the mounting rack 1 or the simulation housing 61, and the image sensor 44 is located on one side of the blocking rack assembly 3 along its length direction. The image sensor 44 is arranged parallel to the mounting beam roller 2 and is used to observe the information of the bullet teeth. The controller 45 is arranged on the mounting cross beam 11 or the mounting longitudinal beam 12 of the mounting rack 1, or the controller 45 is installed on the driver 41. The controller 45 is connected to the driver 41 and is also connected to the image sensor 44. The controller 45 is used to detect the output parameters of the driver 41, and the output parameters of the driver 41 include torque, rotational speed, etc. The controller 45 processes and outputs the real-time stress state of the bullet teeth according to the output parameters of the driver 41. At the same time, the controller 45 is also used to receive the information of the bullet teeth transmitted by the image sensor 44, and the information of the bullet teeth includes the image of the bullet teeth. The controller 45 analyzes based on the information of the bullet teeth and records the information on the fracture or wear of the bullet teeth.

[0071] Optionally, not shown in the figure, the strain module can adopt a strain gauge of the Somat-XR model of HBM, and the strain gauge can also be called a rugged data acquisition system. The strain gauge of the strain module is attached to the power input end of the mounting beam roller, and the strain module is used to detect the stress on the mounting beam roller when the spring teeth collide with the baffle assembly. When the drive module drives the mounting beam roller to rotate, the strain gauge detects the degree of deformation of the mounting beam roller when it is stressed during rotation, and transmits the relevant data to the strain module through a wireless transmission device (such as a Bluetooth transmission device). The strain module converts the relevant processing into corresponding stress data and transmits the stress data to the controller 45.

[0072] Application scenario of an exemplary embodiment:

[0073] As Figures 1 to 7 shown, the spring teeth are arranged in the mounting groove 23 of the mounting member 22, and the spring teeth are arranged at the mounting hole 24. The spring teeth are mounted on the mounting member 22 of the mounting beam roller 2 through gaskets and bolts. Multiple spring teeth of different specifications and models are arranged in the mounting groove 23 of the same mounting member 22, so that the service life of spring teeth of different models and specifications can be tested under the same operating environment. Of course, multiple spring teeth of the same specification and model can also be arranged in the mounting groove 23 of the same mounting member 22, so that the accuracy of the test data can be improved by increasing the number of test spring teeth. At the same time, multiple spring teeth of another same specification and model can also be arranged in the mounting groove 23 of another mounting member 22, so that the service life of spring teeth of different models and specifications can be tested under the same operating environment. By the cooperation of the first bolt 42 and the second bolt 43, the position of the baffle assembly 3 is adjusted so that the spring teeth strike the baffle assembly 3 for testing. When the baffle assembly 3 is used to simulate the operating scenario on the ground, the degree of deformation of the spring teeth on the ground can be tested. Of course, the position of the baffle assembly 3 can also be adjusted to test the degree of deformation of the spring teeth under different distances from the ground.

[0074] After the baffle assembly 3 is fixed, the protective cover 62 is covered, which can prevent the spring teeth from splashing and hurting people after breaking, and also prevent the simulated experimental materials from spilling out of the accommodation cavity 611. The driver 41 is started, and the driver 41 drives the driving wheel 51 to rotate. The driving wheel 51 drives the driven wheel 52 to rotate through the transmission belt 53, and the driven wheel 52 drives the mounting shaft 21 to rotate. The spring teeth rotate with the mounting shaft 21 and continuously strike the nylon plate 33 of the baffle assembly 3. In this way, the maximum deformation angle of the spring teeth is tested. Of course, simulated experimental materials can also be placed in the simulation shell 61 according to needs. Such a setting can simulate the operating environment of a typical sandy gravel plot and test the wear condition of the spring teeth.

[0075] Second Embodiment

[0076] This embodiment discloses a method for testing spring teeth, which is implemented based on the spring tooth testing device disclosed in the first embodiment. This spring tooth testing method can be regarded as a spring tooth testing method based on the spring tooth testing device.

[0077] When the spring teeth are installed on the mounting beam roller and the driving module drives the mounting beam roller to rotate and drives the spring teeth to collide with the baffle component, in this embodiment, it simulates the situation where the spring teeth are in a planar working condition. As Figure 8 shown, a method for testing spring teeth disclosed in this embodiment includes:

[0078] S11. Determine the maximum deformation angle of the spring teeth according to the first distance between the baffle component and the mounting beam roller;

[0079] S12. Determine the stress on the mounting beam roller when the spring teeth collide with the baffle component according to the rotational speed of the driving module;

[0080] S13. Determine the actual service life of the spring teeth according to the maximum deformation angle of the spring teeth and the stress on the mounting beam roller.

[0081] In step S11, as Figure 9 、 Figure 10 shown, after the spring teeth are installed on the mounting beam roller, the first angle D is obtained according to the first mathematical model. Specifically, the first mathematical model is:

[0082] D = arccos[(C 2 +L 2 -r 2 ) / (2CL)]

[0083] where C is the distance from the center point of the spring tooth installation to the axis center O of the installation shaft. L is the length of the straight line segment of the spring tooth. R is the maximum installation distance from one side surface of the baffle component to the axis center O of the installation shaft. As Figure 9 shown, X is the distance from the axis center of the second bolt 43 to the hole center of the second waist-shaped hole far from the baffle component. r is the first distance from the side surface of the baffle component close to the mounting beam roller to the axis center O of the installation shaft, and r = R - X.

[0084] The second angle (B + D) is obtained according to the second mathematical model. Specifically, the second mathematical model is:

[0085] (B + D) = arccos[(C 2 +L 2 -R 2 ) / (2CL)]

[0086] Then the maximum deformation angle B of the spring teeth = (B + D) - D.

[0087] In step S12, the state of the spring teeth is detected by the image sensor 44, and the rotation speed of the drive module is detected in combination with the controller 45. When the drive module rotates one circle, the spring teeth undergo an elastic deformation once. Each time the spring teeth collide with the stop frame assembly, the strain module can detect the stress on the mounting beam roller. At the same time, the image sensor 44 also detects the spring teeth. When the spring teeth are broken or chipped, the image sensor 44 feeds back the condition of the spring teeth to the controller 45. The controller 45 stops detecting the rotation speed of the drive module and outputs the total number of circles accumulated by the drive module before the spring teeth are broken or chipped. The total number of circles of the drive module is the actual total number of deformations of the spring teeth, and the actual total number of deformations of the spring teeth can be regarded as the actual service life of the spring teeth.

[0088] In step S13, after the spring teeth break, the controller sorts out the stress data and elastic deformation data of the spring teeth during the entire cycle from the start of the test to the break, and outputs a graph of the stress on the mounting beam roller - the number of spring tooth deformations. From the graph of the stress on the mounting beam roller - the number of spring tooth deformations, the stress on the mounting beam roller when the spring teeth collide each time can be obtained, so that the actual total number of deformations of the spring teeth can be determined.

[0089] In the above method, spring teeth of the same specification and model are used, and the actual service life of spring teeth of the same specification and model can be tested.

[0090] Optionally, when testing the spring teeth, the position of the stop frame assembly can be adjusted in real time according to the test requirements to simulate different working conditions. After the position adjustment of the stop frame assembly is completed, X is re - determined, and the re - determined r is obtained according to the re - determined X. The re - determined r is substituted into the first mathematical model and the first angle D is re - obtained. The maximum deformation angle B of the spring teeth is re - determined according to the second angle (B + D) and the first angle D. In this embodiment, the actual service life of spring teeth of the same specification and model under different working conditions can be tested. Of course, spring teeth of other specifications and models can also be replaced to test the actual service life of spring teeth of other specifications and models under different working conditions.

[0091] Optionally, when the harvester performs a baling operation on the forage, the effective duration for the picker to perform a baling operation on a bale of forage is the first duration H, and the rotational speed E of the picker of the harvester is determined. The rotational speed of the drive module is set to be the same as the rotational speed of the picker of the harvester. According to the rotational speed E of the drive module and the first duration H, the number of deformations that the spring teeth undergo within the first duration can be determined, that is, the number of deformations that the spring teeth undergo within the first duration is E * H. Then, first, the number of bales F that the harvester bales the forage per day is determined. According to the number of bales F that the harvester bales the forage per day and the number of deformations that the spring teeth undergo within the first duration being E * H, the number of deformations that the spring teeth undergo in one day can be determined as F * (E * H). Dividing the total actual deformation number of the spring teeth by the number of deformations that the spring teeth undergo in one day, which is F * (E * H), the total actual service days of the spring teeth can be determined, and the total actual service days of the spring teeth can also be regarded as the actual service life of the spring teeth.

[0092] Optionally, for example, spring teeth of the same specification and model can be installed on the mounting beam roller using different types of washers such as flat washers, elastic washers, and special-shaped washers. The actual service life of the spring teeth under different installation methods can be tested by adjusting the installation method of the spring teeth. After adjusting the installation method of the spring teeth on the mounting beam roller, according to the installation method of the spring teeth on the mounting beam roller and the rotational speed of the drive module, the stress on the mounting beam roller when the spring teeth collide with the baffle assembly can be re-determined.

[0093] Different from the prior art, by installing the spring teeth on the mounting beam roller, the driver drives the mounting beam roller to rotate and makes the spring teeth on the mounting beam roller strike the baffle assembly. Through such a test method, the actual service life of the spring teeth can be quickly measured.

[0094] An exemplary embodiment:

[0095] Install the spring teeth on the mounting beam roller, and drive the mounting beam roller to rotate through the drive module. Install the baffle assembly on the top of the mounting frame, and record the position of the baffle assembly. Here, the position of the baffle assembly refers to the distance between the nylon plate and the axis center of the mounting shaft. Through the first mathematical model and the second mathematical model of this embodiment, the maximum deformation angle of the spring teeth in this installation position can be calculated. Adjust the baffle assembly to different positions through the cooperation of the first bolt and the second bolt, so as to calculate the maximum deformation angle of the spring teeth in different positions of the baffle assembly. After the position of the baffle assembly is determined, cover the protective cover and start the driver. The driver drives the mounting beam roller to rotate through the transmission component, and the spring teeth rotate accordingly and strike the baffle assembly and undergo periodic elastic deformation. At this time

[0096] The notification period obtains the total actual deformation of the spring teeth by detecting the rotational speed of the drive. The stress on the mounting beam roller is also detected by the strain module, and the deformation or fracture of the spring teeth at different times is detected by the image sensor. Through the above methods, the stress-deformation times diagram of the mounting beam roller during the entire cycle of the spring teeth from the start of the test until fracture can be measured, and the total actual deformation of the spring teeth in this case can be obtained.

[0097] After testing this spring tooth and obtaining a set of data, reinstall the spring teeth of the same specification and model, and readjust the position of the retaining frame assembly. Conduct the above experiment here to obtain various data of the spring teeth under another maximum deformation angle.

[0098] In this embodiment, according to the spring tooth testing method of this embodiment, an exemplary experimental data table is also given. In this exemplary experiment, the only difference is the change in the position of the retaining frame, and the other conditions are the same. Specifically as follows (the units of X, R, r, C, and L are all mm):

[0099]

[0100] Through the above spring tooth deformation angle comparison table, it can be known that the larger X is, the larger the deformation angle B of the spring teeth is. As the position of the retaining frame assembly is adjusted, the nylon plate moves away from the mounting beam roller, X gradually decreases, and the deformation angle B of the spring teeth also gradually decreases.

[0101] Third Embodiment

[0102] This embodiment also discloses a spring tooth testing method, which is implemented based on the spring tooth testing device disclosed in the first embodiment. This spring tooth testing method can be regarded as a spring tooth testing method based on the spring tooth testing device.

[0103] Remove the retaining frame assembly and place the simulated experimental material in the accommodating cavity of the simulated housing. When the spring teeth are installed on the mounting beam roller, the drive module drives the mounting beam roller to rotate and drives the spring teeth to pass through the simulated experimental material in the accommodating cavity of the simulated housing. As Figure 11 shown, a spring tooth testing method also disclosed in this embodiment includes:

[0104] S21. Determine the depth of the spring teeth entering the simulated experimental material according to the straight segment length of the spring teeth;

[0105] S22. Determine the stress on the mounting beam roller when the spring teeth enter the simulated experimental material according to the rotational speed of the drive module;

[0106] S23. Determine the wear condition of the spring teeth according to the image information before and after the spring teeth pass through the simulated experimental material;

[0107] S24, determining the actual service life of the spring teeth according to the depth of the spring teeth penetrating into the simulated experimental material, the stress on the mounting beam roller, and the wear of the spring teeth.

[0108] In step S21, the straight line length of the spring tooth is first determined according to the specification and model of the spring tooth, and then the height of the simulated experimental material in the accommodating cavity of the simulated shell is determined. According to the straight line length of the spring tooth and the height of the simulated experimental material in the accommodating cavity of the simulated shell, the depth of the spring tooth entering the simulated experimental material can be determined.

[0109] In step S22, the state of the spring teeth is detected by the image sensor 44, and the rotation speed of the driving module is detected in combination with the controller 45. When the driving module rotates one circle, the spring teeth pass through the simulated experimental material once, and the spring teeth undergo elastic deformation once. Every time the spring teeth undergo deformation, the strain module can detect the stress on the mounting beam roller. The deeper the spring teeth enter the simulated experimental material, the greater the angle of deformation of the spring teeth, and the greater the stress on the mounting beam roller.

[0110] In step S23, the image sensor 44 collects image information before the spring tooth enters the simulated experimental material and image information after the spring tooth enters the simulated experimental material, compares the image information after the spring tooth enters the simulated experimental material with the image information before the spring tooth enters the simulated experimental material, and determines the wear condition of the straight segment of the spring tooth. When the spring tooth breaks or breaks, the image sensor 44 feeds back the spring tooth condition to the controller 45, and the controller 45 stops detecting the rotation speed of the driving module and outputs the total number of turns of the driving module accumulated before the spring tooth breaks or breaks. The total number of turns of the driving module is the actual total number of deformations of the spring tooth, which can be regarded as the actual service life of the spring tooth.

[0111] In step S24, when the spring tooth breaks, the controller organizes the stress data of the spring tooth from the start of the test to the break and the wear of the spring tooth, and outputs a stress-spring tooth loss diagram of the mounting beam roller. According to the depth of the spring tooth entering the simulated experimental material and the stress-spring tooth loss diagram of the mounting beam roller, the stress of the mounting beam roller and the wear of the spring tooth can be obtained each time the spring tooth passes through the simulated experimental material, so that the actual service life of the spring tooth can be determined.

[0112] Different from the prior art, by setting the simulation shell on the top of the mounting frame, the opening of the accommodating chamber of the simulation shell is located directly below the mounting beam roller, and the test materials such as sand, gravel, soil, and water are crushed in the accommodating chamber of the simulation shell, which can be used to simulate the working environment of sandstone plots, land, etc. The driver drives the mounting beam roller to rotate through the transmission assembly and makes the spring teeth on the mounting beam roller continuously pass through the test materials in the accommodating chamber. In this way, the actual service life of the spring teeth can be continuously and accurately detected without stopping the machine.
