Description

Technical Field

[0001] This invention relates to the field of sugarcane harvesting technology, specifically to a high-efficiency sugarcane leaf-removing device and its usage method. Background Technology

[0002] After sugarcane matures, it needs to be harvested. The harvested sugarcane still has leaves, which need to be removed. In some developed areas with large-scale sugarcane production, sugarcane leaf stripping machines are used for this purpose. Currently, sugarcane leaf stripping machines include a sugarcane harvesting device. The harvesting device cuts down the sugarcane growing in the field, and then a feeding mechanism feeds the cut sugarcane into the leaf stripping mechanism, which then completes the leaf stripping operation.

[0003] Most current sugarcane leaf stripping devices use deformable stripping elements to compress the sugarcane leaf sheaths. In this situation, the stripping element is in an unstable state, and the strong force at the contact point causes it to tend to slide towards the edge of the sugarcane leaf. Once the stripping element slides to the side wall of the sugarcane, it loses its function of stripping the sugarcane leaves.

[0004] Therefore, incomplete leaf removal can occur during the leaf-removal process, ultimately failing to achieve a thorough leaf removal effect. To solve the above problems, there is an urgent need for a high-efficiency sugarcane leaf-removal device that can improve leaf-removal efficiency when the problem of leaf-removal elements sliding against the sugarcane sidewall cannot be avoided. Summary of the Invention

[0005] The purpose of this invention is to provide a sugarcane high-efficiency leaf-removing device and its usage method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-efficiency sugarcane leaf stripping device includes a feeding mechanism, a leaf stripping mechanism, and a discharging mechanism. The leaf stripping mechanism includes a rotating roller rotatably disposed inside the leaf stripping device. The rotating roller is provided with a plurality of evenly distributed annular mounting sleeves, and the mounting sleeves are provided with a plurality of circumferentially distributed leaf stripping blades. The leaf stripping blades include a fixed part and an elastic part, and the elastic part can be made of rubber material.

[0008] As a further embodiment of the present invention: wherein, the fixing part is provided with an adjustment mechanism, the adjustment mechanism includes a cavity formed inside the fixing part, a fixing cylinder is fixedly installed inside the cavity, a sliding block is slidably connected inside the fixing cylinder, the top of the sliding block is fixedly connected to an elastic part, and a return spring with one end connected to the sliding block is provided inside the fixing cylinder.

[0009] As a further embodiment of the present invention, the fixed cylinder has a vertical groove and a spiral groove inside.

[0010] As a further embodiment of the present invention, the inlet of the spiral groove is lower than the upper port of the vertical groove.

[0011] As a further embodiment of the present invention: a guide ball is fixedly installed on the side wall of the sliding block, and the guide ball is slidably connected to the vertical groove and the spiral groove.

[0012] As a further aspect of the present invention, the process of the guide ball moving on the vertical groove or the spiral groove includes process W, process P and process O.

[0013] As a further embodiment of the present invention, the spiral groove is designed to rotate one revolution from top to bottom along the inside of the fixed cylinder.

[0014] A method for using a high-efficiency sugarcane leaf-removing device includes the following steps:

[0015] Open the leaf-removing device, and the feeding mechanism will feed the sugarcane into the leaf-removing mechanism for leaf removal.

[0016] The rotating roller in the leaf stripping mechanism drives the mounting sleeve and the leaf stripping blade to rotate synchronously.

[0017] During process W, the guide ball moves along the vertical groove;

[0018] In process P, the guide ball enters the spiral groove from the vertical groove;

[0019] In process O, after the guide ball passes the inlet, it enters the spiral groove from the vertical groove during the return journey;

[0020] After the sugarcane leaves are removed, it is discharged from the discharge mechanism.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this embodiment, when the force applied by the elastic part to the sugarcane is not large (i.e., it does not exceed the inlet of the spiral groove in the vertical groove), this state occurs because the sugarcane stalk diameter is relatively thin. The contact area between the thin sugarcane stalk and the elastic part is large, resulting in a large force point. Therefore, it is difficult for the elastic part to slip under this state. Under the action of peeling the leaves, it can act on the sugarcane leaves, and under the rotation of the rotating roller, the leaves connected to the sugarcane leaf sheath can be separated to achieve the leaf peeling effect.

[0023] 2. In this embodiment of the leaf-peeling device, when the sugarcane stalk diameter increases, the contact area between the force-bearing point of the elastic part and the sugarcane decreases, which can easily lead to the force-bearing point shifting and causing lateral slippage. Because the stalk diameter is thicker, the guide ball travels a greater distance in the vertical groove. If the force exerted by the elastic part on the sugarcane does not shift when it passes the entrance of the spiral groove, the guide ball will pass the entrance and come above the entrance of the spiral groove; if it shifts, it will directly enter the spiral groove from the entrance, thus achieving the effect of the guide ball rotating in the spiral groove. In this process, the sugarcane can also be peeled efficiently.

[0024] 3. In this embodiment, if the leaf-removing device deviates after passing the inlet, the guide ball will enter the spiral groove from the inlet during its return journey from the vertical groove, and the aforementioned rotation will also occur. The elastic part will generate a torsional force, thereby efficiently removing the sugarcane leaves. Attached Figure Description

[0034] Please see Figure 1This is a schematic diagram of the overall structure in this embodiment. From the direction the sugarcane enters, it sequentially includes a feeding mechanism 10, a leaf-peeling mechanism 30, and a discharging mechanism 20. The feeding mechanism 10 and the discharging mechanism 20 use the same drive motor. This same drive motor ensures that the feeding mechanism 10 and the discharging mechanism 20 rotate at the same speed, thus achieving the same discharge speed. The multiple rotating rollers 31 in the leaf-peeling mechanism 30 are also driven by three motors connected in series. This arrangement facilitates adjustment of the rotation of the three motors and ensures that their rotation speeds remain consistent. In use, sugarcane can be fed into the feeding mechanism 10. As the feeding mechanism 10 rotates, the sugarcane enters the leaf-peeling mechanism 30, where the leaves are removed.

[0035] Two sets of rotating rollers 31 are provided. Multiple evenly distributed annular mounting sleeves 32 are provided on each rotating roller 31, and multiple circumferentially distributed peeling blades 33 are provided on each mounting sleeve 32. To improve the leaf removal effect, the following improvement is made based on the existing technology: the peeling blade 33 includes a fixed part 331 and an elastic part 332, the elastic part 332 being made of rubber. In use, when the peeling blade 33 rotates with the rotating rollers 31 and comes into contact with the sugarcane, the elastic part 332 deforms upon contact with the sugarcane, and the direction of deformation is opposite to the direction of the sugarcane's movement. Therefore, while the elastic part 332 is subjected to deformation force, it also exerts a reverse force on the sugarcane. Thus, the elastic part 332 acting on the sugarcane leaf achieves the effect of separating the sugarcane leaf from the sugarcane leaf sheath, even when the speed of the sugarcane's movement is inconsistent with the rotation speed of the rotating rollers 31. The peeled sugarcane is discharged from the discharge mechanism 20.

[0036] Furthermore, such as Figure 2As shown, the fixing part 331 is fixedly connected to the mounting sleeve 32, and an adjustment mechanism 40 is provided on the fixing part 331. The adjustment mechanism 40 includes a groove 41 opened inside the fixing part 331. A fixing cylinder 42 is fixedly installed inside the groove 41. A sliding block 43 is slidably connected inside the fixing cylinder 42. The top of the sliding block 43 is fixedly connected to the elastic part 332. A return spring 44 with one end connected to the sliding block 43 is provided inside the fixing cylinder 42. A vertical groove 42a and a spiral groove 42b are opened inside the fixing cylinder 42. In this embodiment, when the rotating roller 31 rotates, the elastic part 332 of the peeling blade 33 comes into contact with the sugarcane. The elastic part 332 first undergoes compression deformation to form a first deformation zone M. After the first deformation zone M is formed, due to the presence of the return spring 44, when the force causing the elastic part 332 to deform is less than the "anti-deformation force" of the elastic part 332 in the first deformation zone M state but greater than the deformation force of the return spring 44, the elastic part 332 remains unchanged in the state under the first deformation zone M and moves radially along the mounting sleeve 32 under the contraction of the return spring 44. This process is marked as the second deformation zone N for the elastic part 332. When it continues to move upwards, the return spring 44 gradually increases its elastic force. When the elastic force is greater than the "anti-deformation force" of the elastic part 332 under the first deformation zone M, the elastic part 332 continues to deform, forming a third deformation zone Q. When the elastic part 332 faces sugarcane with different cross-sections, the deformation of the elastic part 332 occurs in the above three states: M, N, and Q. After completing the three states in the first level, it will enter the other three states in the next level, and continue until the elastic part 332 slides sideways from the sugarcane contact surface or the elastic part 332 leaves the sugarcane.

[0037] like Figures 3 to 7As shown, the lateral slippage occurs because when the elastic force increases, the elastic part 332 deviates from the force on the sugarcane, causing it to slide off the top surface of the sugarcane. To ensure that the elastic part 332 can slide upwards in the positive direction in the different states described above, a guide ball 431 is fixedly installed on the side wall of the sliding block 43. The guide ball 431 is slidably connected to the vertical groove 42a and the spiral groove 42b. During the up-and-down sliding of the sliding block 43, the guide ball 431 slides inside the vertical groove 42a. At this time, the guide ball 431 exerts a small force on the side wall of the vertical groove 42a. However, when the elastic part 322 shifts laterally, due to the obstruction of the sugarcane itself, the side of the elastic part 322 closer to the sugarcane experiences a larger force, which applies an outward pushing force to the elastic part 322. At this time, the top of the elastic part 322 experiences an opposite force (i.e., towards the sugarcane). At this time, due to the side slip, the elastic part 322 is limited by the deformation force of the sugarcane and disappears, and the sliding block 43 will slide downward inside the fixed cylinder 42; at this time, due to the existence of the spiral groove 42b, when the guide ball 431 with the opposite force passes through the spiral groove 42b, it will enter the spiral groove 42 during the return process.

[0038] Furthermore, after the guide ball 431 enters the spiral groove 42, because the spiral groove 42b is designed to rotate one revolution from top to bottom along the inside of the fixed cylinder 42, the sliding block 43 will rotate inside the fixed cylinder 42 after the guide ball 431 enters the spiral groove 42b. Since the sliding block 43 is fixedly connected to the elastic part 322, it will also drive the elastic part 322 to rotate together. During the rotation of the elastic part 322, a torsional force will be generated. After the side sliding, the elastic part 322 slides from the top of the sugarcane into the side wall of the sugarcane. At this time, the elastic part 322 will rotate. The rotating elastic part 322 has a torsional force. Under the action of the torsional force, it will provide a strong pulling force on the sugarcane leaves on the sugarcane leaf sheath, thereby causing the sugarcane leaves to detach from the sugarcane leaf sheath.

[0039] Working principle: During the use of this device, sugarcane first enters the leaf peeler through the feeding mechanism 10, and then enters the leaf peeling mechanism 30. As the rotating roller 31 in the leaf peeling mechanism 30 rotates, it drives the mounting sleeve 32 and the peeling blade 33 to rotate synchronously. The rotation direction of the two sets of peeling rollers 31 is the same as the direction of sugarcane movement. When the elastic part 332 in the peeling blade 33 contacts the top of the sugarcane, it will deform. During the deformation process, it will generate a squeezing force on the sugarcane. As the squeezing force gradually increases, that is, when it enters the first deformation zone M, the second deformation zone N, and the third deformation zone Q, the elastic part 322 moves inside the fixed part 331, that is, the sliding block 43 slides towards the center inside the fixed cylinder 42. As the elastic part 322 changes in the above three zones, until the elastic part 322 slides sideways or the elastic part 322 smoothly leaves the top surface of the sugarcane. Sideslip occurs because, under increasing force, the elastic part 322 deviates from the direction of force applied to the sugarcane, causing it to slip. When the force applied by the elastic part 322 to the sugarcane is small (i.e., does not exceed the inlet of the spiral groove 42b in the vertical groove 42a), this occurs because the sugarcane stalk diameter is relatively thin. A thinner stalk results in a larger contact area with the elastic part 322, thus a larger force-bearing point. Therefore, it is difficult for the elastic part 322 to slip under these conditions. The movement of the guide ball 431 during this process is denoted as process W. However, when the sugarcane stalk diameter increases, the contact area between the force-bearing point of the elastic part 322 and the sugarcane decreases, making it easier for the force-bearing point to deviate and cause sideslip. Because of its larger diameter, the guide ball 431 travels a greater distance in the vertical groove 42a. If the force exerted by the elastic part 332 on the sugarcane does not deflect when it passes the entrance of the spiral groove 42b, the guide ball 431 will pass the entrance and arrive above the entrance of the spiral groove 42b. If a deflection occurs, it will directly enter the spiral groove 42b from the entrance, thus achieving the effect of the guide ball 431 rotating in the spiral groove 42b. The elastic part 322 is provided with a torsional force, and the motion of the guide ball 431 during this process is denoted as process P. If a deflection occurs after passing the entrance, the guide ball 431 will enter the spiral groove 42b from the entrance during its return journey from the vertical groove 42b. The motion of the guide ball 431 during this process is denoted as process O. When the force on the elastic part 332 disappears, it will rotate along the spiral groove 42b under the action of the return spring 44 until the elastic force of the return spring 44 disappears. At this time, the guide ball 431 will enter the vertical groove 42a from the outlet of the spiral groove 42b.

[0040] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
