Description

Technical Field

[0001] The invention belongs to the technical field of sugarcane seed stem processing equipment, and in particular relates to an intelligent production line for sugarcane seed stems. Background Art

[0002] Healthy sugarcane seed stems are one of the important factors to ensure sugarcane yield and benefits. With the advancement of science and technology, the processing of sugarcane seed stems has gradually changed from farmers' self-storage seed production to factory seed production. The supporting sugarcane seed stem intelligent production line is an important part of factory seed production.

[0003] The existing sugarcane seed stem production line can refer to the patent "A Sugarcane Seed Stem Cutting Production Line" (CN110547066A). This patent can cut sugarcane stalks neatly and quickly into sugarcane seed stems through a cutting device; when the sugarcane seed stems are transported by the conveying device, the side slide and the bending belt mechanism can put the sugarcane seed stems in a direction parallel to the conveying direction, which is convenient for packing. Although this patent can realize rapid factory seed production, it cannot intelligently identify sugarcane bud nodes. It is necessary to manually place sugarcane and move it to achieve cutting. A production line generally has more than 20 seed cutting stations, and each station must be equipped with workers, which is more labor-intensive. If fixed-distance blind cutting is used, it cannot guarantee that each section of the seed stem has the required number of bud nodes, and it is very likely that the cutting place is on the bud node (causing bud damage) or very close to the bud node, affecting the germination of sugarcane. The patent "A Sugarcane Intelligent Seed Cutting Platform and Method" (CN118476344A) can detect the delivered sugarcane in real time, identify the bud nodes of the sugarcane in real time before cutting, and ensure that each sugarcane segment has sprouts. However, the sugarcane seed stems are fed by insertion, which is more laborious and easy to damage the sugarcane buds. The sugarcane seed stems are cut by horizontal pushing, which consumes more energy than the guillotine pushing and cutting, and the sugarcane stems squeeze out more water. Summary of the invention

[0019] Compared with the existing technology, the present invention has the following beneficial effects:

[0020] 1. The present invention is provided with a conveying device, an identification device, a cutting device and a control device. When in use, the identification device identifies the sugarcane bud node by image recognition technology, and the control device determines the cutting position by the position of the bud node. When the sugarcane is transported to the predetermined position, the control device controls the conveying device to stop the conveying of the sugarcane, and controls the cutting device to cut the sugarcane, and so on.

Among them, the identification device is arranged between the conveying device and the cutting device, which can better determine the cutting position of the sugarcane (cutting in the middle between two sugarcane bud nodes), and better guarantee the quality of the sugarcane seed stem.

[0021] 2. The cutting device of the present invention realizes guillotine-style cutting of sugarcane by installing the cutter and the cutter rotating motor on a rotating plate hinged to the housing, and the rotating plate is driven by the telescopic cylinder to swing. Compared with the traditional horizontally pushed cutter, part of the gravity of the cutter and the cutter rotating motor can be converted into the cutting force for cutting sugarcane, which is conducive to the rapid cutting of sugarcane stems, which can not only save energy consumption, but also improve the cutting efficiency of sugarcane.

Compared with the original hinge point of the rotating plate being set at the lower part of the housing, the bagasse and sugarcane juice generated by cutting sugarcane will not splash or accumulate on the hinge point of the rotating plate, and the rotation resistance of the rotating plate will not be increased, and it is not easy to fail.

[0022] 3. The conveying device of the present invention is provided with a first conveying wheel and a second conveying wheel that can slide along the slide rail, and an inclined sugarcane guide plate is provided above the first conveying wheel and the second conveying wheel. When in use, the sugarcane is placed between the first conveying wheel and the second conveying wheel, and then the second conveying wheel is driven by the mobile motor to clamp the sugarcane seed stem, and then the first conveying wheel and the second conveying wheel are driven by the rotating motor to rotate to convey the sugarcane to the sugarcane cutting device for cutting. The second conveying wheel of the device can move along the slide rail under the drive of the mobile motor, and the sugarcane can be placed and then clamped and conveyed. Compared with the traditional method of manually inserting the sugarcane directly between the sugarcane conveying wheel groups, it is not easy to damage the sugarcane bud nodes. Among them, the first conveying wheel is fixed to the frame by a spring, and the second conveying wheel is connected to the vertical plate driven by the mobile motor by a spring. It can be adaptively adjusted according to the size of the sugarcane seed stem to meet the transportation needs of sugarcane seed stems of different sizes or bends.

[0023] 4. The first conveying wheel and the second conveying wheel of the conveying device of the present invention are both nylon wheels, and the inside of the wheel is a grid with holes, that is, the first conveying wheel and the second conveying wheel have a certain elasticity and are not easy to pinch the sugarcane buds; at the same time, the outer periphery of the first conveying wheel and the second conveying wheel is set in a concave-convex pattern, which is not easy to slip and is conducive to the transportation of sugarcane seed stems. The nylon wheel can be made by 3D printing technology, and compared with rubber wheels, it has a longer service life and is not easy to slip.

[0024] 5. The present invention improves the conveying device, so that sugarcane can be placed from top to bottom, and a robot can be used to operate on the side. The robot arm can pick up the sugarcane in the sugarcane placing vehicle and place it in the sugarcane placing trough for identification and transmission, which is conducive to the full mechanization of sugarcane seed stems and better realizes intelligence and integration.

The following is an explanation of the embodiments of the present invention based on its overall structure.

[0037] Example 1

[0038] like Figure 1 As shown, a sugarcane seed stem intelligent production line includes a frame 1, a conveying device 2, an identification device 3, a cutting device 4 and a control device 5. The conveying device 2 is used to convey sugarcane, the identification device 3 is used to identify the bud nodes on the sugarcane, and the cutting device 4 is used to cut the sugarcane. The conveying device 2, the identification device 3 and the cutting device 4 are respectively electrically connected to the control device 5. When in use, the identification device 3 identifies the sugarcane bud node through image recognition technology, and the control device 5 determines the cutting position according to the position of the bud node. When the sugarcane is conveyed to the predetermined position, the control device 5 controls the conveying device 2 to stop conveying the sugarcane, and controls the cutting device 4 to cut the sugarcane, and so on.

[0039] The production line sets the identification device 3 between the conveying device 2 and the cutting device 4, which can better determine the cutting position of the sugarcane. That is, the identification device 3 cooperates with the control device 5 to locate the cutting position in the middle between two sugarcane bud nodes, thereby improving the quality of cutting the sugarcane seed stems. At the same time, the present application improves the structure of the conveying device 2 and the cutting device 4, which is not easy to damage the sugarcane bud nodes and can improve the quality of sugarcane cutting. The production line can solve the problem that the existing sugarcane seed stem production line cannot ensure that each section of the seed stem has the required number of bud nodes and cannot achieve efficient and energy-saving cutting, and better meet the needs of factory seed production.

[0040] Combination Figure 2 The conveying device 2 includes: a sugarcane placing trough 21 and a sugarcane conveying wheel group, wherein the sugarcane placing trough 21 is used to place sugarcane, and the sugarcane conveying wheel group is used to clamp and convey the sugarcane to the cutting device 4. Specifically, the combination Figure 3The sugarcane conveying wheel group includes a first conveying wheel 23 and a second conveying wheel 24 driven by a rotating motor 22, a slide rail 25, a first fixed frame 26, a second fixed frame 27, a moving motor 28 and a pushing base 29. The slide rail 25 is arranged horizontally and perpendicular to the extending direction of the sugarcane placing groove 21. The first fixed frame 26, the second fixed frame 27 and the pushing base 29 are respectively slidably connected to the slide rail 25 and can slide along the slide rail 25. The side of the first fixed frame 26 away from the second fixed frame 27 is connected to the frame 1 through a spring. The first conveying wheel 23 is installed on the first fixed frame 26, that is, the first fixed frame 26 can only slide in a small range along the slide rail 25 within the elastic range of the spring. The second conveying wheel 24 is mounted on the second fixed frame 27. The side of the second fixed frame 27 away from the first fixed frame 26 is connected to the pushing base 29 through a spring. The pushing base 29 is driven by the mobile motor 28 to move along the slide rail 25, that is, the second fixed frame 27 can move along the slide rail 25 under the drive of the mobile motor 28 to clamp or loosen the sugarcane. At the same time, the second fixed frame 27 and the pushing base 29 are connected by a spring, and can be adaptively adjusted according to the size or curvature of the sugarcane to better meet the transportation requirements of different sugarcanes. Specifically, a vertical plate 291 with a screw hole is provided on the pushing base 29. The output shaft of the mobile motor 28 is a rotating screw rod. The rotating screw rod passes through the screw hole of the vertical plate 291. When the rotating screw rod of the mobile motor 28 rotates, the vertical plate 291 moves along the slide rail 25. The mobile motor 28 can rotate forward and reverse, that is, the vertical plate 291 and the pushing base 29 can move back and forth along the slide rail 25. The vertical plate 291 is connected to the second fixed frame 27 through a spring, thereby driving the second fixed frame 27 to move along the slide rail 25. The moving motor 28 is fixed to the frame 1, and the moving motor 28 and the rotating motor 22 are respectively electrically connected to the control device 5, and the control device 5 controls whether to work and whether to work forward or reverse. Specifically, the moving motor 22 is equipped with a current detection device, and the current detection device is electrically connected to the control device 5. When the moving motor 22 drives the second fixed frame 27 to move and clamp the sugarcane, the current detection device detects that the current increases, and the control device 5 controls the moving motor 22 to stop moving.

[0041] Specifically, the rotating motor 22 is installed on the outside of the first fixing frame 26 and the second fixing frame 27 respectively, and the output shaft of the rotating motor 22 is connected to the rotating shaft of the first conveying wheel 23 or the second conveying wheel 24 through a gear commutator. The first conveying wheel 23 and the second conveying wheel 24 have the same structure and are both made of nylon wheels. In this embodiment, the nylon wheels are made of 3D printing. Figure 4The first conveying wheel 23 and the second conveying wheel 24 are annular structures, and a rotating shaft connected to the output shaft of the rotating motor 22 is inserted in the middle. At the same time, the first conveying wheel 23 and the second conveying wheel 24 are further fixed to the rotating shaft by screws driven in horizontally. Of course, in other embodiments, the first conveying wheel 23 and the second conveying wheel 24 can also be fixed to the rotating shaft by glue or other methods. Furthermore, the tops of the first fixing frame 26 and the second fixing frame 27 are respectively provided with inclined sugarcane guide plates 6, and the sugarcane guide plates 6 are used to guide the sugarcane between the first conveying wheel 23 and the second conveying wheel 24. The sugarcane enters the first conveying wheel 23 and the second conveying wheel 24 from top to bottom from the sugarcane guide plate 6 for transportation. Compared with the traditional method of inserting the sugarcane between the first conveying wheel 23 and the second conveying wheel 24 from the feed end, it is not easy to squeeze the sugarcane buds, and the distance that the sugarcane needs to be transported is shorter.

[0042] Combination Figure 5 The cutting device 4 comprises: a housing 41, a rotating plate 42, a cutter 43, a cutter rotating motor 44 and a telescopic cylinder 45. The rotating plate 42 is hinged to the upper inner part of the housing 41, the cutter rotating motor 44 is installed at the middle and lower part of the rotating plate 42, the output rod of the cutter rotating motor 44 passes through the rotating plate 42, the cutter 43 is installed on the output rod, and the rotating plate 42 is further provided with an outwardly protruding positioning part 421 at one end away from the hinge point of the rotating plate 42. One end of the telescopic cylinder 45 is hinged to the upper inner part of the housing 41 and the housing 41 at one end away from the cutter 43, and the other end is hinged to the positioning part 421. The telescopic cylinder 45 drives the rotating plate 42 to swing around the hinge point of the rotating plate 42 during the extension and retraction process, thereby driving the cutter 43 to cut the sugarcane. The movement of the telescopic cylinder 45 is controlled by a pneumatic solenoid valve, and the pneumatic solenoid valve and the cutter rotating motor 44 are electrically connected to the control device 5. When the sugar cane is transported to the set position, the control device 5 controls the telescopic cylinder 45 and the rotation of the cutter rotating motor 44 to cut the sugar cane. Preferably, an anti-collision portion 422 is provided at the lower part of the rotating plate 42 and at the end away from the cutter 43. An anti-collision rubber is fixed on the anti-collision portion 422. The anti-collision rubber can be fixed on the anti-collision portion 422 by glue. The provision of the anti-collision rubber can prevent the rotating plate 42 from hitting the housing 41 during the swinging process. In this embodiment, the rotating plate 42 is hinged to the upper part of the casing 41, one end of the telescopic cylinder 45 is hinged to the upper inner part of the casing 41 and the end of the casing 41 away from the cutter 43, and the other end is hinged to the positioning part 421 at the lower part of the rotating plate 42. Compared with the original rotating plate 42 in which the hinge point is set at the lower part of the casing 41, bagasse and sugarcane juice produced by cutting sugarcane will not splash or accumulate on the hinge point of the rotating plate 42, will not increase the rotation resistance of the rotating plate 42, and is less likely to malfunction.

[0043] Furthermore, in this embodiment, the recognition device 3 is an image recognition device 3, which can accurately identify sugarcane buds through a large number of flower bud picture training systems in the early stage, ensuring that each cut sugarcane stem has a set number of sugarcane buds, thereby better ensuring the emergence rate and sowing density.

[0044] When in use, the whole sugarcane stem is placed from top to bottom in the sugarcane placing groove 21, wherein the end of the sugarcane stem is placed between the first conveying wheel 23 and the second conveying wheel 24. The control device 5 controls the moving motor 28 to work, and the second conveying wheel 24 approaches the first conveying wheel 23 to clamp the sugarcane stem, and then the control device 5 controls the rotating motor 22 to rotate, and the first conveying wheel 23 and the second conveying wheel 24 rotate to convey the sugarcane stem to the front cutting device 4. At the same time, the identification device 3 identifies the sugarcane buds on the sugarcane stem, and the control device 5 determines the cutting position according to the position of the bud node. When the sugarcane is transported to the predetermined position, the control device 5 controls the conveying device 2 to stop conveying the sugarcane, and controls the cutting blade rotating motor 44 and the telescopic cylinder 45 of the cutting device 4 to work to cut the sugarcane, and so on. After cutting a sugarcane stem, the control device 5 controls the moving motor 28 to reverse, and the second conveying wheel 24 moves to the end away from the first conveying wheel 23. When the sugarcane stem is put in again, the above-mentioned clamping, conveying and cutting actions are repeated.

[0045] In other embodiments, the production line may also be equipped with a mechanical arm and a sugarcane placing vehicle, in which sugarcane is placed, and the mechanical arm is used to pick up the sugarcane in the sugarcane placing vehicle and place it in the sugarcane placing slot 21. The mechanical arm can be purchased on the market, and can realize the actions of clamping, transferring, putting down, and releasing the sugarcane. The use of the mechanical arm can better realize the intelligent processing of sugarcane seed stems.

[0046] In summary, the present invention uses intelligent identification and automatic cutting control to ensure that each section of sugarcane stems cut contains the required number of sugarcane bud nodes, thereby better ensuring the quality of sugarcane stems. At the same time, the present application improves the structure of the conveying device 2 and the cutting device 4, which is not easy to damage the sugarcane bud nodes and can improve the quality of sugarcane cutting.
