Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of agricultural leaf stripping devices, and particularly relates to a healthy sugarcane stem processing automatic leaf stripping machine without damaging buds. BACKGROUND

[0002] Sugarcane healthy stem processing needs to strip the leaves of the cut sugarcane before cutting it into single-bud stems or double-bud stems, then soaking and coating agents and drying. The existing sugarcane stem leaf stripping mainly adopts a centrifugal leaf stripping method, and the corresponding leaf stripping device structure mainly includes a conveying device, a leaf stripping device and a power device. The working principle is to use the high-speed rotating leaf stripping element to repeatedly hit and pull to separate the sugarcane leaves and the cane stems.

The first conveying rollers are provided with bristles on the outer periphery.

[0007] The second conveying mechanism comprises second conveying rollers and hard rollers arranged oppositely up and down. A sugarcane conveying channel is left between the second conveying rollers and the hard rollers. The second conveying rollers are provided with bristles on the outer periphery. The diameter of the hard rollers is smaller than that of the second conveying rollers. The first conveying rollers and the second conveying rollers are driven by the power mechanism. The rotating direction of the second conveying rollers is opposite to that of the first conveying rollers arranged above the sugarcane stems. The hard rollers are hinged to the rack and can rotate with the movement of the sugarcane stems.

[0008] The leaf stripping mechanism is arranged below the second conveying mechanism, and comprises two first leaf stripping rollers and two second leaf stripping rollers which rotate towards each other and are driven by the power mechanism; the surfaces of the first leaf stripping rollers and / or the second leaf stripping rollers are concave-convex.

[0013] Preferably, a limiting roller is arranged between two adjacent groups of leaf stripping mechanisms, the limiting roller is arranged below the hard roller, and the two ends of the limiting roller are hinged to the frame respectively.

[0014] Preferably, the hard roller has two, and the two hard rollers are arranged above the outer sides of the two leaf stripping rollers respectively.

[0015] Preferably, the surfaces of the first leaf stripping rollers and the second leaf stripping rollers comprise concave-convex rubber layers.

[0016] Preferably, the first conveying mechanism has 2-6 groups. Preferably, the first conveying mechanism has 2-4 groups.

[0017] Preferably, the conveying mechanism further comprises a conveying belt arranged in front of the first conveying mechanism and / or arranged behind the second conveying mechanism.

[0018] Compared with the prior art, the present application has the following beneficial effects:

[0019] 1. The present application sets the first conveying mechanism and the second conveying mechanism for the conveying mechanism, wherein the outer periphery of the two first conveying rollers of the first conveying mechanism and the second roller of the second conveying mechanism are provided with bristles, which can adapt to the conveying of sugarcane with different stem diameters compared with the traditional hard conveying roller, and will not damage the sugarcane buds.

[0020] 2. The present application sets the leaf stripping device below the second conveying mechanism, and the sugarcane leaves are clamped and pulled by the first leaf stripping roller and the second leaf stripping roller rotating towards each other, so that the sugarcane leaves are separated from the sugarcane stems. Compared with the traditional leaf stripping roller which directly clamps the sugarcane stems, the first leaf stripping roller and the second leaf stripping roller of the present application leave a gap with the conveyed sugarcane stems, and will not contact the sugarcane buds, which can reduce the damage to the sugarcane buds.

The distance between the first leaf stripping roller and the second leaf stripping roller can be adjusted as needed to meet the leaf stripping needs of different amounts of sugarcane leaves, and is not prone to blockage.

[0022] 4. The present application sets a leaf arranging mechanism below the leaf stripping mechanism, wherein the leaf arranging mechanism comprises a leaf arranging groove and a fan. The fan is selected to be a negative pressure fan. The setting of the fan can form a negative pressure in the leaf arranging groove, which is conducive to the extension of the sugarcane leaves to the leaf stripping mechanism and the clamping and pulling of the leaf stripping mechanism. At the same time, the sugarcane leaves stripped by the leaf stripping mechanism can also be discharged outward.

[0023] 5. The present application can set a conveying belt in front of the conveying mechanism of the leaf stripping machine. The sugarcane stems automatically enter the first conveying mechanism of the leaf stripping machine through the conveying belt, and are automatically stripped by the leaf stripping mechanism under the driving of the conveying roller with bristles. The degree of automation is high. The present leaf stripping machine can simultaneously strip the leaves of multiple sugarcane, which greatly improves the leaf stripping efficiency compared with the traditional one-by-one sugarcane leaf stripping.

[0030] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0031] like Figures 1-3 As shown, an automatic leaf-stripping machine for processing healthy sugarcane seed stalks without damaging the buds includes a frame 1, a conveying mechanism 2, a leaf-stripping mechanism 3, a leaf-removing mechanism 4, and a power mechanism 5. The frame 1 is used to fix the conveying mechanism 2, the leaf-stripping mechanism 3, and the leaf-removing mechanism 4; the leaf-stripping mechanism 3 is located below the conveying mechanism 2, and the leaf-removing mechanism 4 is located below the leaf-stripping mechanism 3. The power mechanism 5 is used to drive the conveying mechanism 2, the leaf-stripping mechanism 3, and the leaf-removing mechanism 4 respectively. The sugarcane seed stalks are held and conveyed forward by the conveying mechanism 2, and the leaf-stripping mechanism 3 is used to pull the sugarcane leaves and separate them from the sugarcane stalks. The leaf-removing mechanism 4 is used to collect the sugarcane leaves and impurities, and discharges them to a designated location via a fan 42.

[0032] Specifically, the conveying mechanism 2 includes a first conveying mechanism 21 and a second conveying mechanism 22. The first conveying mechanism 21 has two sets, spaced apart in front of the second conveying mechanism 22. Each first conveying mechanism 21 includes two vertically opposite first conveying rollers 211 that rotate towards each other, gripping the sugarcane stalk and conveying it to the second conveying mechanism 22. The outer periphery of each first conveying roller 211 is provided with bristles 212, and a sugarcane conveying channel 6 is provided between the two rollers. That is, the sugarcane stalk is conveyed forward under the grip of the bristles 212. Compared to traditional hard rollers 222, the use of bristles 212 can adapt to sugarcane of different stalk diameters and reduce damage to the sugarcane buds. In other embodiments, the number of first conveying rollers can also be set differently.

[0033] Specifically, the second conveying mechanism 22 includes a second conveying roller 221 and a hard roller 222 arranged vertically opposite each other. A sugarcane conveying channel 6 is also provided between the second conveying roller 221 and the hard roller 222. The outer periphery of the second conveying roller 221 is provided with bristles 212. The diameter of the hard roller 222 is smaller than the diameter of the second conveying roller 221. The first conveying roller 211 and the second conveying roller 221 are driven by the power mechanism 5. The rotation direction of the second conveying roller 221 is opposite to the rotation direction of the first conveying roller 211 located above the sugarcane stalk. The opposite rotation direction of the second conveying roller 221 is beneficial for prying open the sugarcane leaves, making it easier for the sugarcane leaves to enter the leaf-peeling mechanism. The hard roller 222 is hinged to the frame 1 and can rotate with the movement of the sugarcane stalk. The second conveying roller 221 is the active roller, which drives the sugarcane stalk forward. The hard roller 222 is the passive roller, mainly providing support for the sugarcane stalk and preventing it from directly contacting the leaf-peeling mechanism 3. In this embodiment, there are three hard rollers 222, which are respectively located above the center of the leaf-peeling mechanism 3 and above both sides of the leaf-peeling mechanism 3. The hard rollers 222 can be smooth metal rollers or plastic rollers.

[0034] Combination Figures 2-3The leaf-peeling mechanism 3 has two sets. Each leaf-peeling mechanism 3 includes two opposing leaf-peeling rollers 31 and 32, driven by the power mechanism 5. The surfaces of the first and second leaf-peeling rollers 31 and 32 are irregularly shaped. Preferably, the surfaces of the first and second leaf-peeling rollers 31 and 32 include an irregularly shaped rubber layer. The irregularly shaped surfaces of the leaf-peeling rollers make it easier to grip and pull the sugarcane leaves. Specifically, the first leaf-peeling roller 31 is fixed to the frame 1 at both ends by bearings. The second leaf-peeling roller is fitted with bearing sleeves 7 with swing rods 71 ​​at both ends. The other end of the swing rods 71 ​​is hinged to the frame 1. The side of the second leaf-peeling roller away from the first leaf-peeling roller is fixed to the frame 1 by an elastic element 8. That is, the distance between the second and first leaf-peeling rollers is adjustable, which can meet the leaf-peeling needs of different amounts of sugarcane leaves and is less prone to clogging. Even if sugarcane stalks are caught in the leaf-peeling mechanism 3 during the leaf-peeling process, they can be removed without causing blockage. Specifically, the elastic element 8 includes a fixed sleeve 81, an adjusting screw 82, and a spring 83. The fixed sleeve 81 is fixed to the frame 1, and its inner side is threaded. The adjusting screw 82 is threadedly connected to the fixed sleeve 81. One end of the adjusting rod has an adjusting part, and the other end of the adjusting screw 82 is fixed with the spring 83. The spring 83 extends outside the fixed sleeve 81 and abuts against the second leaf-stripping impeller. In use, by rotating the adjusting part, the lateral position of the adjusting screw 82 and the spring 83 can be adjusted, thereby adjusting the distance between the second leaf-stripping impeller and the first leaf-stripping impeller. In other embodiments, a limiting roller is provided between two adjacent sets of leaf-stripping mechanisms 3. The limiting roller is located below the hard roller 222, and both ends of the limiting roller are hinged to the frame 1. The limiting roller prevents sugarcane leaves from entering between the two sets of leaf-stripping mechanisms 3 and affecting leaf removal.

[0035] Combination Figure 4 The leaf-removing mechanism 4 includes a leaf-removing groove 41 and a fan 42. The leaf-removing groove 41 is located below the leaf-peeling mechanism 3, and the fan 42 is located at one end of the leaf-removing groove 41. A leaf outlet is provided on the side of the leaf-removing groove 41 near the fan 42. Preferably, the bottom of the leaf-removing groove 41 is inclined towards the fan 42 end, which is beneficial for the discharge of sugarcane leaves and impurities. Further, the fan 42 is a negative pressure fan 42. The negative pressure fan 42 can create negative pressure in the leaf-removing groove 41, which is beneficial for the sugarcane leaves to extend towards the leaf-peeling mechanism 3 and be clamped and pulled by the leaf-peeling mechanism 3. At the same time, it can also discharge the sugarcane leaves peeled by the leaf-peeling mechanism 3. In this embodiment, the fan 42 and the leaf-peeling mechanism 3 are connected by a transmission device and share a motor. The conveying mechanism 2 is powered by another motor. The motor speed of the leaf-peeling mechanism 3 is greater than the speed of the conveying mechanism 2.

[0036] Combination Figure 3To use this leaf-stripping machine to peel sugarcane leaves, start the power mechanism 5 to activate the conveying mechanism 2, leaf-stripping mechanism 3, and leaf-discharging mechanism 4. Insert the head of the sugarcane stalk into the sugarcane conveying channel 6 in the middle of the first conveying mechanism 21. The second conveying mechanism 22 conveys the sugarcane stalk to the second conveying mechanism 22. The second conveying roller 221 of the second conveying mechanism 22 flips, lifting the sugarcane as well. Under the negative pressure of the fan 42 of the leaf-discharging mechanism 4, the sugarcane extends towards the leaf-stripping mechanism 3. The second conveying mechanism 22 drives the sugarcane to continue moving forward. The leaf-stripping mechanism 3 pulls the sugarcane leaves, separating them from the sugarcane stalk. The sugarcane leaves fall into the leaf-discharging trough 41 of the leaf-discharging mechanism 4 and are discharged from the leaf outlet under the action of the fan 42. The sugarcane stalk continues to move forward under the drive of the first conveying mechanism 21 and the second conveying mechanism 22. After peeling the leaves, it is discharged from the rear of the second conveying mechanism 22.

[0037] In other embodiments, the conveying mechanism 2 further includes a conveyor belt located in front of the first conveying mechanism 21 and behind the second conveying mechanism 22. The conveyor belt located in front of the first conveying mechanism 21 may also be equipped with longitudinal partitions, allowing the sugarcane to enter the first conveying mechanism 21 vertically and automatically enter the leaf-peeling mechanism 3 for leaf peeling under the drive of a conveyor roller with brushes, resulting in a high degree of automation. The leaf-peeling machine of this embodiment can peel multiple sugarcanes simultaneously, further improving peeling efficiency compared to the traditional method of peeling leaves from one sugarcane at a time.

[0038] In summary, the outer periphery of both the first conveying roller 211 and the second roller of the conveying mechanism 2 of this invention is provided with bristles 212. Compared with traditional hard conveying rollers, this design can adapt to the conveying of sugarcane with different stem diameters and will not damage the sugarcane buds. The leaf-peeling device is located below the second conveying mechanism 22, with a gap between it and the conveyed sugarcane stalks, thus avoiding contact with the sugarcane buds and reducing damage to them. Simultaneously, this application uses the first leaf-peeling roller 31 and the second leaf-peeling roller 32 to clamp and pull the sugarcane leaves, resulting in better force distribution and higher leaf-peeling efficiency compared to directly beating the leaves. This leaf-peeling machine can also be combined with a conveyor belt for automatic feeding and can simultaneously peel leaves from multiple sugarcane stalks, further improving leaf-peeling efficiency.

These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the invention, as well as various different choices and variations.
