Description

Technical Field

[0001] The invention relates to the technical field of sugarcane processing, and in particular to an intelligent sugarcane segmenting machine. Background Art

[0002] Sugarcane segmentation technology refers to the process of cutting harvested sugarcane into segments to meet the needs of eating or keeping seeds. This technology is of great significance for the subsequent processing and utilization of sugarcane. In the sugarcane planting and processing industry, segmentation is an important link in the sugarcane processing process, which directly affects the utilization rate, product quality and production efficiency of sugarcane. With the development of agricultural mechanization, sugarcane segmentation technology is also constantly improving. The traditional sugarcane segmentation method mainly relies on manual operation, which is inefficient and labor-intensive. In order to improve production efficiency and reduce labor intensity, mechanized and automated sugarcane segmentation devices came into being.

[0003] At present, there are many sugarcane segmentation devices on the market. Most of these devices use mechanized methods to segment sugarcane by rotating blades or cutting tools. These devices have the characteristics of simple structure, convenient operation, and high efficiency, and are widely used in the sugarcane planting and processing industry. However, the existing sugarcane segmentation devices still have some shortcomings in terms of segmentation quality and intelligence. For example, the segmentation length and section quality of some devices are not stable enough, and are easily affected by factors such as sugarcane diameter and hardness; at the same time, most of these devices lack intelligent control and cannot be adaptively adjusted according to the actual situation of sugarcane.

[0004] At the same time, most of the above-mentioned devices rely on image recognition technology to determine whether sugarcane can be used for seed preservation and the cutting position. However, this solution often requires collecting image information of sugarcane in at least two directions, and image recognition often requires a large amount of computing resources, which will undoubtedly increase the cost of the device.

[0005] Moreover, most of the above-mentioned devices use hydraulic equipment to control the guillotine to cut the sugarcane into segments. There is a risk of leakage during the operation of the hydraulic equipment, which will cause food contamination to the sugarcane, which will undoubtedly increase the loss during the sugarcane processing. Summary of the invention

[0006] In order to solve the above problems, the present invention provides a sugarcane intelligent segmenting machine, which is used to reduce the probability of contamination of sugarcane during the cutting process.

The component works, and the feeding component is controlled to work according to the degree of bending of the sugarcane. When the sugarcane meets the seed retention standard, the image information of the sugarcane is obtained, and the wormhole positioning information of the sugarcane and the cross-section status of the sugarcane are obtained according to the image information. The accuracy of the wormhole positioning information is greater than the wormhole position of the sugarcane. When a hollow core or a red core appears in the cross-section of the sugarcane, the alarm is controlled to alarm the user.

[0010] Furthermore, rubber sleeves are provided at the ends of the moving rods which are away from each other.

[0011] Furthermore, the cutting assembly includes a cutting ring, which is coaxially arranged with a fixed ring. A guillotine is provided on the cutting ring. A pneumatic telescopic rod is provided on the top wall of the guillotine. The pneumatic telescopic rod is used to push the guillotine to cut the sugarcane into segments. The pump assembly is connected to the pneumatic telescopic rod, and a solenoid valve is provided at the connection point between the pump assembly and the pneumatic telescopic rod. The control system is used to control the operation of the solenoid valve, the pump assembly and the throttle valve according to the length, diameter, bud point position and wormhole position of the sugarcane.

[0012] Furthermore, a plurality of first electromagnets are provided in the pneumatic telescopic rod, and the first electromagnets are used to limit the length of the pneumatic telescopic rod. The control system is used to control the operation of the first electromagnets according to the length, diameter, bud point position and wormhole position of the sugarcane.

[0013] Furthermore, a plurality of holes are opened on the side wall of the chamber close to the inner side wall of the test ring, and the holes are evenly arranged along the inner side wall of the test ring. Test pieces are provided in the holes, and the test pieces are fixedly connected to the side wall of the chamber close to the elastic parts, and the other end of the elastic parts is fixedly connected to the side wall of the chamber away from the side wall piece.

[0014] Further, the control system includes a controller, symmetrically arranged cameras, a rotation speed sensor and a number of distance sensors;

[0015] The distance sensors are used to collect distance information between the side wall of the test piece close to the chamber and the side wall of the chamber far from the test piece;

[0016] The rotation speed sensors are used to collect the rotation speed information of the moving rod;

[0017] The cameras are used to collect image information of sugarcane;

[0018] The controller is used to obtain the distance moved by the sugarcane according to the rotation speed information and the size of the moving rod, obtain the deformation information of the side wall of the chamber according to the size of the distance information and the position of the distance sensor corresponding to the distance information, and obtain the length of the sugarcane according to the distance moved by the sugarcane, obtain the diameter, curvature, bud point position and wormhole position of the sugarcane according to the size and distribution state of the deformation information of the side wall of the chamber, and judge whether the sugarcane meets the seed retention standard according to the diameter, curvature and wormhole position of the sugarcane.

When the sugarcane meets the seed retention standard, the image information of the sugarcane is obtained, and the wormhole positioning information of the sugarcane is obtained according to the image information.

The controller is also used to control the operation of the second electromagnets according to image information, length, diameter, degree of curvature, bud point position, wormhole position and wormhole positioning information of the sugarcane.

[0020] Furthermore, the controller is also used to receive the wormhole position and the corresponding length of sugarcane to be discarded input by the user, and use a neural network to build an association between the wormhole position and the corresponding length of sugarcane to be discarded, and correct the length of the edible part through the association.

[0021] Furthermore, in the distance information, each test piece corresponds to distance information of at least three different positions, and when the difference between the distance information corresponding to the same test piece is greater than a preset value, the controller controls the alarm to operate.

[0022] Furthermore, it also includes a receiving component, which includes a plurality of net bags, which are detachably connected to the machine tool and arranged longitudinally. The mesh density of the net bags decreases from bottom to top, and the net bags are used to collect cut sugarcane.

[0023] Furthermore, the exhaust port is arranged on any side of the connection between the net bag and the machine tool.

[0024] Furthermore, the controller is also used to control the alarm to warn the user according to the rotation speed information.

[0025] Technical principles and beneficial effects of the above scheme:

[0026] Through the design of the test component, this scheme uses a triangular nozzle to spray pressurized air onto the sugarcane skin. After the pressurized air rebounds through the sugarcane skin, it impacts the inner wall of the test ring, thereby causing the inner wall of the test ring to deform. By collecting the size and position of the deformation of the inner wall of the test ring, the diameter, curvature, bud point position and wormhole position of the sugarcane are obtained, so as to make a preliminary judgment on whether the sugarcane can be used for seed preservation. When the sugarcane cannot be used for seed preservation, the sugarcane nodes and wormhole positions are cut off to retain the edible part of the sugarcane. Whenever the sugarcane can be used for seed preservation, the image information of the sugarcane is obtained, and based on the sugarcane image, a further judgment is made on whether the sugarcane can be used for seed preservation.

[0027] Compared with the prior art scheme that uses image recognition throughout the process to judge whether sugarcane needs to be kept for seed and the cutting position, this scheme can perform preliminary screening of sugarcane, greatly reduce the amount of sugarcane that needs to be image recognized, avoid interference from external background and light on the judgment of the sugarcane cutting position and whether the sugarcane can be used for seed, and avoid some judgment errors caused by the limitations of image recognition technology, such as the problem that the judgment results are easily affected by insufficient or poor quality training data. At the same time, since image acquisition is often required to collect image information of sugarcane in at least two directions when judging the sugarcane cutting position and whether the sugarcane can be used for seed, this scheme only needs to collect image information in one direction after making a preliminary judgment on the sugarcane status, which greatly reduces the amount of information processing, thereby also reducing the probability of errors caused by image recognition misjudgment.

[0028] At the same time, the pressurized air sprayed from the triangular nozzle onto the surface of the sugarcane can clean the sugarcane skin to a certain extent during the collision with the sugarcane skin, thereby reducing the pollution of the dirt on the sugarcane skin to other sections of sugarcane, affecting the consumption and storage time of the sugarcane. In addition, since the triangular nozzles are evenly arranged along the inner wall of the test ring, the air sprayed from the triangular nozzles can provide a certain support to the sugarcane, so that it can be roughly located at the axis of the test ring, avoiding collision between the sugarcane and the test ring, causing damage to the sugarcane or the test ring. The test ring can also test sugarcanes of different diameters, thereby improving the scope of application of the device.

[0029] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Due to the action of the spring, when there is no external force, the side of the test piece 42 away from the spring is flush with the inner wall of the test ring 41, thereby closing the corresponding hole.

[0045] The feeding assembly 5 includes a fixing ring 51 and a pushing rod 53. The fixing ring 51 is fixed by welding to the machine tool 1, and the fixing ring 51 is coaxially arranged with the test ring 41.

The nozzles 521 are evenly arranged along the side wall of the annular airbag 52. The nozzles 521 are all connected to the pump assembly. A throttle valve is provided at the connection between the nozzle 521 and the triangular nozzle 43 and the pump assembly. The annular airbag 52 is connected to a hose, and a hose is provided at the connection between the hose and the annular airbag 52. The pressure relief valve and the check valve are located near the nozzle 521. An exhaust port is provided at one end of the hose away from the annular airbag 52. A fan-shaped groove is provided on the machine tool 1, and the push rod 53 is hinged to the side wall of the fan-shaped groove. The hose is used to drive the push rod 53 to rotate. A moving rod 54 is also hinged on the machine tool 1. The ends of the moving rods 54 that are away from each other are provided with rubber sleeves 541. The moving rod 54 and the push rod 53 are coaxially hinged. The moving rod 54 is used to drive the sugarcane to move in the direction of the cutting assembly 3. The cutting assembly 3 includes a cutting ring 31, which is coaxially arranged with the fixing ring 51. A guillotine 32 is provided, and a pneumatic telescopic rod 33 is provided on the top wall of the guillotine 32. The pneumatic telescopic rod 33 includes a shell, and a driving chamber is slidably matched in the shell. The pneumatic telescopic rod 33 is used to push the guillotine 32 to cut the sugarcane. The pump components are connected to the driving chamber, and the connection between the pump components and the chamber and the driving chamber is provided with an electromagnetic valve. The inner wall of the shell and the side wall of the inner rod 332 are fixedly connected with a plurality of first electromagnets by bolts. The first electromagnet is used to limit the length of the pneumatic telescopic rod 33. The control system also includes a controller, a speed sensor, and a symmetrical arrangement along the axis of the test ring 41. Two cameras and several distance sensors 44 are arranged on both sides of the machine tool 1. The controller and the camera are fixedly connected to the machine tool 1 by bolts. The distance sensors 44 are fixedly connected to the side wall of the chamber away from the test piece 42 by bolts. The rotation speed sensor and the moving rod 54 are coaxially fixedly connected to the hinge of the machine tool 1 by bolts. The distance sensors 44 are used to collect the distance information of the side wall of the test piece 42 close to the chamber from the side wall of the chamber away from the test piece 42. The rotation speed sensors are used to collect the rotation speed information of the moving rod 54. The cameras are used to collect the image information of the sugarcane.The camera, the alarm, the speed sensor, the distance sensor 44, the first electromagnet, the throttle valve, the solenoid valve and the pump assembly are all electrically connected to the controller. The controller is used to obtain the distance moved by the sugarcane according to the speed information and the size of the moving rod 54, and use the distance moved by the sugarcane to obtain the length of the sugarcane, and obtain the deformation information of the chamber side wall according to the size of the distance information and the position of the distance sensor 44 corresponding to the distance information (in other embodiments, the deformation information of the chamber side wall can also be collected using a strain gauge bracket), and obtain the diameter, curvature, bud point position and wormhole position of the sugarcane according to the size and distribution state of the deformation information of the chamber side wall, and judge whether the sugarcane meets the seed retention standard according to the sugarcane diameter, curvature and wormhole position. When the sugarcane does not meet the seed retention standard, the sugarcane is judged to be suitable for seed retention. When the seed retention standard is met, the length of the edible part of the sugarcane is calculated according to the length of the sugarcane, the position of the wormhole and the position of the bud point, and the first electromagnet and the electromagnetic valve pump assembly are controlled to work according to the length of the edible part. At the same time, the pump assembly and the throttle valve are controlled to work according to the bending degree of the sugarcane. When the sugarcane meets the seed retention standard, the image information of the sugarcane is obtained, and the wormhole positioning information of the sugarcane is obtained according to the image information. The accuracy of the wormhole positioning information is greater than the position of the wormhole of the sugarcane. The position and length of the seed retention are determined according to the diameter of the sugarcane, the position of the bud point and the wormhole positioning information. There is a bud point and no wormhole at the position of the seed retention, and the first electromagnet, the electromagnetic valve and the pump assembly are controlled to work according to the position and length of the seed retention. The controller is also used to control the alarm to alarm the user according to the speed information. ;

[0046] The specific implementation process is as follows: during the use of the device, any end of the sugarcane to be preliminarily processed is placed in the device, and the device is started. The controller controls the pump assembly and the throttle valve to work, and gas is continuously and stably pumped into the annular airbag 52. The annular airbag 52 is gradually filled and contacts the outer surface of the sugarcane to fix the sugarcane. As the amount of gas pumped into the annular airbag 52 increases, the air pressure in the annular airbag 52 gradually rises. When it exceeds the threshold of the pressure relief valve, the pressure relief valve opens, allowing the gas inside the annular airbag 52 to enter the hose. Due to the design of the push rod 53, its end cooperates with the side wall of the fan-shaped groove, thereby squeezing the hose and preventing the gas in the hose from flowing out of the hose through the exhaust port, causing the air pressure inside the hose to rise. Due to the action of the check valve, the gas inside the hose cannot The air in the hose 54 can flow back into the annular airbag 52, and under the action of air pressure, the push rod 53 is pushed to rotate. As the push rod 53 rotates, the distance between its end and the side wall of the fan-shaped groove gradually increases, and the gas in the hose can be discharged through the exhaust port. In this process, as the push rod 53 rotates, the push rod 53 drives the moving rod 54 to rotate, and the end of the moving rod 54 contacts the sugarcane and pushes the sugarcane to move in the direction of the guillotine 32. The design of the rubber sleeve 541 is conducive to increasing the friction between the end of the moving rod 54 and the sugarcane, reducing the situation where the moving rod 54 slips and causes the sugarcane to be unable to be pushed, thereby affecting the judgment of the length of the sugarcane. At the same time, through the design of the rubber sleeve 541, the moving rod 54 can also adapt to sugarcanes of different diameters, avoiding the influence of the moving rod 54 on the subsequent collection of various data of the sugarcane.

[0047] As the sugarcane moves, it enters the test ring 41, and the controller controls the pump assembly and the corresponding throttle valve to open, and pressurized air is sprayed onto the surface of the sugarcane through the triangular nozzle 43. When the pressurized air is sprayed onto the surface of the sugarcane, due to the interaction force between the two, some air molecules collide with the sugarcane, rebound from the surface of the sugarcane, and impact the inner wall of the test ring 41. Since the contact position of the air molecules and the sugarcane surface is not consistent, the angle of the tangent corresponding to the movement trajectory and the contact position is also inconsistent, so that the gas molecules in contact with different positions on the sugarcane surface have different impact positions on the inner wall of the test ring 41. Therefore, the position where the test ring 41 is impacted by the gas can be obtained to roughly judge the bud point position and the wormhole position of the sugarcane. At the same time, after the gas is ejected by the triangular nozzle 521, Due to the resistance of the external air, its kinetic energy will be reduced accordingly. Therefore, the longer the time from the air molecules being ejected from the triangular nozzle 43 to the time the air molecules contact the surface of the sugarcane, the longer the distance between the triangular nozzle 43 and the surface of the sugarcane, that is, the distance between the sugarcane at this position and the inner wall of the test ring 41 is greater. By integrating all the distance information, the approximate diameter of the sugarcane can be obtained. At the same time, according to the diameter and the change trend and change value of the distance information between each triangular nozzle 43 and the surface of the sugarcane during the movement of the sugarcane, the degree of bending of the sugarcane can be obtained. Since the bud point of the sugarcane is often located at the node of the sugarcane, and the sugarcanes at both ends of the node often have differences in diameter or angle, the position of the sugarcane node can be obtained by combining the change in diameter with the change in the degree of bending, and thus the position of the sugarcane bud point can be obtained. When sugarcane is infested with insects, wormholes caused by insects are likely to appear on the surface of the sugarcane. When some of the air molecules sprayed from the triangular nozzle 43 enter the wormhole, the position of the gas molecules that impact the inner wall of the test ring 41 after rebounding is significantly different from the impact position of other gas molecules. Therefore, by judging whether mutation data occurs, it is possible to obtain whether there is a wormhole in the sugarcane and the approximate position of the wormhole (i.e., the position of the wormhole in the sugarcane).

[0048] In this process, the controller determines whether the sugarcane meets the seed retention standard based on the sugarcane diameter, bending degree and wormhole position. If the sugarcane diameter is too small, the bending angle is too large or there are too many wormholes, the sugarcane cannot meet the seed retention standard. At this time, the controller calculates the appropriate length of the edible part of the sugarcane based on the obtained sugarcane length, wormhole position and bud point position. For example, the edible part is X centimeters before and after the bud point and B centimeters before and after the wormhole.

[0049] At the same time, the controller controls the first electromagnet to work, and the first electromagnet generates magnetic force to fix the relative position of the inner rod 332 and the outer tube 331 (in the initial state, due to the friction between the side wall of the inner rod 332 and the inner wall of the outer tube 331, in the absence of external force, the inner rod 332 is not easy to move downward under the action of gravity). Then the pump assembly and the solenoid valve work to pump gas into the drive chamber. As the air pressure inside the drive chamber rises, when the edible part of the sugarcane reaches below the guillotine 32 according to the length of the edible part of the sugarcane, the controller cuts off the power supply of the first electromagnet. Due to the action of air pressure, the guillotine 32 falls quickly to cut the sugarcane. Then the controller controls the pump assembly to work again, extracts the gas in the drive chamber, and drives the guillotine 32 and the pneumatic telescopic rod 33 to reset through air pressure, and performs the cutting action at the next position, thereby completing the cutting of this part. Compared with the scheme of pumping gas into the driving chamber when the guillotine 32 needs to be driven, the design of the first electromagnet drives the guillotine 32 faster, shortening the processing time of the sugarcane. At the same time, since the guillotine 32 has a larger initial velocity, the speed of the guillotine 32 when in contact with the sugarcane is also larger, so that the sugarcane is not easily affected by the guillotine 32 and deformed, which is beneficial to maintaining the flatness of the sugarcane cross section and improving the quality of the sugarcane segment.

[0050] As the sugar cane moves, the tail end of the sugar cane reaches a position where it cannot be touched by the moving rod 54 at the top layer. At this time, the moving rod 54 cannot continue to drive the sugar cane to move toward the position of the guillotine 32. Due to the lack of resistance from the sugar cane, the rotation speed of the moving rod 54 will increase to a certain extent. That is, when the rotation information increases within a unit time, and the increased value is greater than the preset value, the feeding component 5 cannot continue to push the sugar cane to move, and the controller controls the alarm to alarm the user, prompting the user to adjust the sugar cane or end the cutting of the sugar cane.

[0051] When the sugarcane meets the seed retention standard, the controller starts the camera closest to the wormhole position according to the wormhole position, obtains the image information of the sugarcane at that position, and obtains the wormhole positioning information of the sugarcane according to the image information. The wormhole positioning information is more accurate than the wormhole position obtained with distance information in the early stage. Through the wormhole positioning information, the sugarcane used for seed retention can be further inspected to avoid retaining some sugarcane contaminated by pests as bud seeds during the cutting process due to the fuzzy wormhole position. At the same time, it can also avoid discarding some sugarcane in normal position due to the fuzzy wormhole position, thereby The sugarcane bud seed loss caused by the sugarcane bud seed loss can also be determined according to the image information whether the sugarcane has a red core. When the sugarcane has a red core, the user is promptly alerted to avoid the red core sugarcane from mixing into the sugarcane seeds, which increases the workload of the subsequent operators. Then, according to the diameter of the sugarcane, the position of the bud point and the wormhole positioning information, the appropriate seed retention position and length are obtained (for example, the segment is cut 5 cm before and after the bud point to achieve seed retention), and the first electromagnet, the electromagnetic valve and the pump assembly are controlled to work according to the appropriate seed retention position and length. By adjusting the length of the pneumatic telescopic rod 33, the sugarcane is cut by the guillotine 32. In this process, if the second half of the sugarcane no longer meets the sugarcane seed retention standard (for example, the diameter of the sugarcane in the second half of the sugarcane no longer meets the sugarcane seed retention standard), the controller will no longer retain the sugarcane, but instead calculate the length of the edible part of the sugarcane, and control the first electromagnet, the electromagnetic valve and the pump assembly to work according to the length of the usable part of the sugarcane, and cut the sugarcane into those segments.

[0052] When faced with sugarcane that does not meet the seed retention conditions, the controller drives the sugarcane to move in the direction of the guillotine 32 through the operation of the controller pump assembly and the throttle valve. According to the continuously obtained bending degree, the controller controls the operation of the throttle valve at the corresponding position to adjust the flow rate of the gas sprayed into the annular airbag 52, so that the impact force exerted on the side wall of the sugarcane by the gas sprayed through the nozzle 521 through the side wall of the annular airbag 52 changes. Due to the different magnitudes of the circumferential impact forces on the sugarcane, the sugarcane moves and rotates until the axis of the sugarcane located at the test ring 41 is roughly perpendicular to the test ring 41 in the bending degree obtained by the test assembly 4, and according to the changing trend of the bending degree, a certain prediction is made on the state of the sugarcane that has not passed the test ring 41, and the flow rate of the gas sprayed from the nozzle 521 is adjusted according to the corresponding prediction structure. For example, a certain sugar cane has an arc-shaped turn that bends to the right at its center. When the sugar cane is cut, when the starting position of the arc-shaped turn enters the test ring 41 and is collected, the controller adjusts the flow rate of the gas ejected from the nozzles 521 on the right and left sides of the sugar cane through the pump assembly and the throttle valve, so that the impact force exerted by the gas ejected from the nozzle 521 on the right side on the sugar cane is greater than that from the nozzle 521 on the left side, pushing the sugar cane to rotate to the left, thereby adjusting the axis of the sugar cane that subsequently enters the test ring 41 and the position of the guillotine 32, so that the axis of the sugar cane that moves to the test ring 41 and the position of the guillotine 32 roughly coincides with the axis of the test ring 41. Subsequently, when the sugar cane turns in an arc After moving to the farthest point to the position of the test ring 41, the collected bending degree changes, that is, the sugarcane was closer to the right side wall of the test ring 41 before, and after passing the farthest point, the sugarcane gradually moves to the left side wall of the test ring 41. The controller predicts the bending angle and length of the sugarcane that has not passed the test ring 41 according to the bending angle and length of the sugarcane, and controls the pump assembly and different throttle valves to work according to the prediction results, so as to adjust the movement direction of the sugarcane through the gas ejected by the nozzle 521, thereby ensuring that the sugarcane segments cut by the guillotine 32 can be cylindrical, avoiding the tilt of the sugarcane cut caused by the sugarcane axis not being perpendicular to the guillotine 32, which affects the consumption and storage of the sugarcane.

[0053] The design of the annular airbag 52 can protect the sugarcane's epidermis, buds and other locations during the process of adjusting the sugarcane through the nozzle 521, avoiding damage to the sugarcane's epidermis and buds caused by direct impact of the airflow. At the same time, the design of the annular airbag 52 also enables the device to adapt to sugarcanes of different diameters and degrees of curvature. At the same time, the design of this solution can reduce the size of the test ring 41 to a certain extent by adjusting the sugarcane axis, thereby reducing the distance from the sugarcane surface to the inner wall of the test ring 41, reducing the impact of air resistance on the pressurized air ejected from the triangular nozzle 43, improving the accuracy of the test of the device, and also reducing the volume of the device to a certain extent, thereby facilitating the storage and transportation of the device.

[0054] At the same time, the design of the test piece 42 in the present scheme ensures that the air pressure in the chamber can be roughly balanced with the external air pressure during the process of the fluid impacting the inner wall of the test ring 41, thereby avoiding the impact of the fluid on the inner wall of the test ring 41, which causes the air pressure in the chamber to rise and hinders the deformation of the inner wall of the test ring 41. Compared with the scheme not involving the chamber, the inner wall of the test ring 41 in the present scheme is easier to deform, and when subjected to the same impact force, the deformation is more obvious and violent, which is conducive to subsequent data collection.

[0055] Embodiment 2:

[0056] The difference from Example 1 is that a cutting knife 34 is further provided on the inner side wall of the cutting ring 31, and a telescopic assembly is provided on the cutting knife 34. The telescopic assembly includes symmetrically arranged extension plates 341, and the extension plates 341 are slidably matched with the side walls of the cutting knife 34. The telescopic assembly is used to adjust the length of the cutting knife 34. Permanent magnets 342 are provided at both ends of the cutting knife 34, and the permanent magnets 342 are hinged to the end of the extension plate 341 away from the cutting knife 34. A guide rail 311 is provided on the cutting ring 31, and the cutting ring 31 is slidably matched with the cutting knife 34 through the guide rail 311, and the guide rail 31 A plurality of second electromagnets 342 are fixedly connected to the side wall away from the cutting knife 34 by bolts, and the second electromagnets 342 are evenly arranged along the inner wall of the guide rail 311. The size of the second electromagnets 342 is slightly smaller than the permanent magnets 342. The second electromagnets 342 are used to drive the two ends of the cutting knife 34 to slide along the inner wall of the cutting ring 31 through the permanent magnets 342. The second electromagnets 342 are electrically connected to the controller, and the controller is also used to control the operation of the second electromagnets 342 according to the image information, the length, diameter, bending degree, bud point position, wormhole position and wormhole positioning information of the sugarcane.

[0057] The specific implementation process is as follows: when using the device, the controller controls the first electromagnet to work according to the length, diameter, bending degree, bud point position, wormhole position and wormhole positioning information obtained through image information, before cutting the sugarcane, the controller controls the corresponding second electromagnet 342 to work according to the diameter of the sugarcane, and adjusts the magnetic force size and direction of the second electromagnet 342 to drive the permanent magnet 342 on one side to move, thereby driving the extension plate 341 to move, and adjusting the relative distance between the two permanent magnets 342 so that the cutting knife 34 and the cutting ring 31 axis are aligned. The vertical distance between the cutting knife 34 and the cutting ring 31 axis increases or decreases. For example, when the vertical distance between the cutting knife 34 and the cutting ring 31 axis is greater than the radius of the sugar cane, the controller controls the second electromagnet 342 close to any permanent magnet 342 and away from the other permanent magnet 342 to work, so that the magnetic pole of the side close to the permanent magnet 342 is opposite to the magnetic pole of the permanent magnet 342, attracting the permanent magnet 342 to move in the direction away from the other permanent magnet 342, thereby pulling the extension plate 341 to move, so that the distance between the two permanent magnets 342 is gradually lengthened until the vertical distance between the cutting knife 34 and the cutting ring 31 axis is slightly less than the radius of the sugar cane. Then the controller simultaneously controls the second electromagnet 342 close to the two permanent magnets 342 to work, by adjusting the direction and magnitude of the current passing through the second electromagnet 342, adjusting the magnitude and direction of the magnetic force of the second electromagnet 342, driving the two permanent magnets 342 to move synchronously along the track, so that the contact position between the cutting knife 34 and the sugar cane moves along the circumferential direction of the sugar cane, and in this process, the cutting knife 34 cuts the sugar cane epidermis.

[0058] The design of the cutting knife 34 and the like, which uses the cutting knife 34 to cut the sugarcane skin before the guillotine 32 cuts the sugarcane into segments, can avoid the sugarcane skin being unable to be completely cut off due to factors such as excessive hardness of the sugarcane skin or insufficient power of the guillotine 32, causing the front and rear sections of the sugarcane to stick together, or causing the sugarcane skin to fall off from the sugarcane segment during the pulling process, thereby affecting the transportation and seed retention of the sugarcane.

[0059] Embodiment 3:

[0060] The difference from Example 2 is that the controller is also used to receive the length of sugarcane that needs to be discarded corresponding to the wormhole position input by the user, and use a neural network to construct an association between the wormhole position and the corresponding length of sugarcane that needs to be discarded, and correct the length of the edible part through the association.

[0061] The specific implementation process is as follows: due to different activities of different pests on sugarcane, the positions and depths of the wormholes they form are also different. Due to the different depths, the inedible ranges caused will also be different. Therefore, this solution uses the wormhole position of the sugarcane wormhole input by the user and the size of the inedible range corresponding to the wormhole (that is, the length of the sugarcane that needs to be discarded), and then uses a neural network to construct an association model between the wormhole position and the corresponding length of the sugarcane that needs to be discarded. In the subsequent use of this device, after the device obtains the wormhole position, the size of the inedible range that the wormhole may correspond to is judged according to the association model, and the length of the edible part is corrected according to the size of the obtained inedible range. Compared with the prior art, this solution is more flexible and is not prone to the use of the same size, resulting in the edible part containing the inedible part, affecting subsequent use, or the inedible part containing part of the edible part, causing waste of sugarcane.

[0062] Embodiment 4:

[0063] The difference from Example 3 is that, in the distance information, each test piece 42 corresponds to distance information of at least three different positions, and when the difference between the distance information corresponding to the same test piece 42 is greater than a preset value, the controller controls the alarm to work.

[0064] The specific implementation process is as follows: When using this device, the distance information of the three different positions of the test piece 42 is collected. While obtaining the distance information between the test piece 42 and the side wall of the chamber, the inclination angle of the test piece 42 can be obtained, so that the position of the pressurized air ejected from the triangular nozzle 43, after rebounding through the sugarcane epidermis, impacting the test piece 42 can be judged, thereby improving the accuracy of the data collected by the device. At the same time, compared with the solution of designing more and smaller test pieces 42, this solution can reduce the difficulty of processing and assembling the test ring 41. At the same time, using the distance information of three different positions, the accuracy of the distance information can be verified to a certain extent. When the difference between the distance information of the three different positions is greater than the set value, the distance sensor 44 corresponding to the test piece 42 may be damaged, and the currently acquired data is not reliable. The controller controls the alarm to work to prompt the user.

[0065] Embodiment 5:

[0066] The difference from Example 4 is that it also includes a receiving component, which includes a plurality of net bags 2, which are detachably connected to the machine tool 1 through buttons, and the net bags 2 are arranged longitudinally, and the mesh density of the net bags 2 decreases from bottom to top. The net bags 2 are used to collect cut sugarcane, and the exhaust port is arranged on either side of the connection between the net bags 2 and the machine tool 1.

[0067] The specific implementation process is as follows: before using the device, the net bags 2 with different mesh densities are connected to the machine tool 1 in turn through buttons, and then the device is started. As the guillotine 32 works, the cut sugarcane gradually enters the net bag 2. Since the upper net bag 2 has a larger mesh density, smaller parts such as sugarcane nodes and sugarcane segments with wormholes fall into the lower net bag 2, while the sugarcane segments that only retain the edible parts pass through the upper net bag 2 and fall into the net bag 2 located in the middle position. Affected by the net bag 2, they no longer continue to move downward. The sugarcane segments that retain bud points often cannot pass through the upper net bag 2 due to their longer length, and thus stay in the upper net bag 2, thereby realizing the sorting of different sugarcane segments, further reducing the work efficiency of the staff, and reducing the contamination of the sugarcane segments with wormholes on the sugarcane segments retaining bud points, thereby increasing the probability of subsequent bud germination.

[0068] At the same time, during the process of the device cutting the sugarcane, due to the action of the push rod 53, the gas discharged from the exhaust port is sprayed intermittently on the net bag 2, giving the net bag 2 an intermittent impact force. This impact force, combined with the mechanical vibration generated by each component during the operation of the device, drives the net bag 2 to vibrate, helping the sugarcane nodes and sugarcane segments to enter the appropriate net bag 2, avoiding the situation where the sugarcane segments or sugarcane nodes are unable to pass through the net bag 2 due to being blocked by a longer sugarcane segment below, thereby improving the sorting accuracy and avoiding subsequent manual sorting.

[0069] At the same time, through the effect of the net bag 2, the residue cut off at the broken end of the sugarcane enters the net bag 2 at the lower layer, reducing the influence of the residue on the taste of the edible part of the sugarcane segment.

[0070] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
