Description

Technical Field

[0001] This utility model relates to a component of a whole-stalk sugarcane harvesting and processing equipment, specifically a sugarcane leaf removal and stalk trimming device, belonging to the field of sugarcane harvesting and processing machinery technology. Background Technology

[0002] Whole-stalk sugarcane harvesting and processing equipment can complete a series of processes in sugarcane fields, including harvesting, conveying, stripping leaves, and topping trimming. Existing whole-stalk sugarcane harvesting and processing equipment typically uses a cantilevered cutter head at the front end to uniformly trim the tops of the sugarcane before harvesting. The harvested sugarcane is then conveyed to a stripping device composed of upper and lower stripping rollers for leaf removal. Because the top heights of individual sugarcane stalks vary considerably, using a cantilevered cutter head to uniformly trim the tops before harvesting makes it difficult to adjust and match the numerous tops of different heights. This easily leads to a large number of missed or over-trimmed tops, resulting in poor topping trimming efficiency. The leaf-peeling device, consisting of upper and lower leaf-peeling rollers, uses leaf-peeling rollers with toothed teeth at both ends to strike and rake the sugarcane leaves covering the sugarcane in the opposite direction, causing the sugarcane leaves to peel off and tear. However, this method of leaf peeling is not very effective for sugarcane leaves that are closely attached to the sugarcane stalk because the force of gripping and tearing the sugarcane leaves is relatively low. Utility Model Content

[0003] The purpose of this invention is to provide a sugarcane leaf removal and sap cutting device that integrates the leaf removal and sap cutting processes of sugarcane into one unit. It can not only remove sugarcane leaves from the sugarcane stalk, but also automatically and accurately cut the tips of different individual sugarcane plants.

[0004] The technical solution adopted in this utility model is as follows: A sugarcane defoliation and pruning device includes a pair of parallel, spaced-apart vertical support plates mounted above the frame. Between the two support plates are a horizontally arranged cylindrical conveyor roller, two swivel conveyor rollers, and a clamping roller. The cylindrical conveyor roller is located at the lower left. One of the swivel conveyor rollers is above the cylindrical conveyor roller and forms a clamping roller pair with it; the other is located to the right of the cylindrical conveyor roller and forms another clamping roller pair with it. The clamping roller is located slightly above the cylindrical conveyor roller and below the upper swivel conveyor roller. The cylindrical conveyor roller has a cylindrical roller body fixedly connected to its roller shaft, and a longitudinal ridge is provided on the outer side of the cylindrical roller body. The swivel conveyor roller has a roller body fixedly connected to its roller shaft, and a set of radially extending rubber swivels are provided on the outer side of the roller body. The clamping roller is a rod roller, with the highest point of its outer circumference aligned with the highest point of the outer circumference of the cylindrical conveyor roller. The outer circumference of the clamping roller is aligned with the outer circumference of the cylindrical conveyor roller. There is a sugarcane clamping gap between them; the ends of the cylindrical conveyor roller, the deflector conveyor roller, and the clamping roller are all rotatably supported by bearings on the bearing supports correspondingly installed on the two upright pallets. A driver is also installed in the frame, which is connected to the roller shafts of the cylindrical conveyor roller, the deflector conveyor roller, and the clamping roller via a chain drive assembly, and drives the cylindrical conveyor roller, the deflector conveyor roller, and the clamping roller to rotate. The cylindrical conveyor roller rotates clockwise when viewed from front to back, while the deflector conveyor roller and the clamping roller rotate counterclockwise when viewed from front to back. Between the two upright pallets, on the right side of the clamping roller, there is a horizontal sugarcane discharge pallet with its top surface flush with the highest point of the outer circumference of the clamping roller. The sugarcane inlet is located on the left side between the two upright pallets, between the corresponding upper deflector conveyor roller and the cylindrical conveyor roller. The sugarcane tip outlet is located on the lower side between the two upright pallets, between the corresponding cylindrical conveyor roller and the right deflector conveyor roller. The sugarcane stalk outlet is located on the right side between the two upright pallets, above the corresponding sugarcane discharge pallet.

[0005] This sugarcane defoliation and stalk trimming device operates by conveying the sugarcane from the stalk tip first, followed by the root. A clamping roller, consisting of an upper conveyor roller and a cylindrical conveyor roller, along with a clamping roller, guides the sugarcane leaves into the clamping gap. The clamping roller, also composed of a right-side conveyor roller and a cylindrical conveyor roller, pulls the leaves downwards to remove them. Once the connecting section between the sugarcane stalk tip and the stem is engaged in the clamping gap, the convex edge of the cylindrical conveyor roller rotates to the clamping gap, where it, along with the clamping roller, clamps and severs the connecting section, completing the stalk trimming. This device is simple in structure and easy to use. Because each sugarcane stalk is trimmed at the connecting section between the stalk tip and the stem, it can automatically and accurately trim the tips of different sugarcane stalks, preventing missed or excessive trimming, thus achieving excellent trimming results. Because the sugarcane is defoliated by using clamping rollers to hold and pull the sugarcane leaves, the gripping and tearing force is good, the sugarcane is defoliated more cleanly, and the defoliation effect is better.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings. In the description of the present invention, the directional terms "upper," "lower," "left," "right," "front," and "rear" are based on the accompanying drawings. Figure 1 The orientation or positional relationship shown is defined only for the convenience of describing this utility model, and does not refer to a specific orientation that the device or component must have, and should not be regarded as a limitation of this utility model.

[0017] like Figures 1-9 As shown, a pair of vertically mounted pallets 1, arranged in parallel and spaced intervals, are mounted above the frame of this sugarcane defoliation and topping device. Between the two pallets 1, a cylindrical conveyor roller 2, two swivel conveyor rollers 3, and a clamping roller 4 are arranged horizontally and longitudinally. The cylindrical conveyor roller 2 is located at the lower left. One of the swivel conveyor rollers 3 is located above the cylindrical conveyor roller 2 and forms a clamping roller pair with it. The other swivel conveyor roller 3 is located to the right of the cylindrical conveyor roller 2 and forms a clamping roller pair with it. The clamping roller 4 is located below the cylindrical conveyor roller. The cylindrical conveyor roller 2 is positioned slightly above the right-side guide roller 3 and below the upper guide roller 3; the cylindrical conveyor roller 2 has a cylindrical roller body fixedly connected to its roller shaft, and a longitudinal ridge 2.1 is provided on the outer side of the cylindrical roller body; the guide roller 3 has a roller body fixedly connected to its roller shaft, and a set of radially extending rubber guide plates are provided on the outer side of the roller body; the pinch roller 4 is a rod roller, and the highest point of the outer circumference of the pinch roller 4 is flush with the highest point of the outer circumference of the cylindrical conveyor roller 2, and the outer circumference of the pinch roller 4 is... There is a gap between the rollers and the sugarcane. The roller shafts of the cylindrical conveyor roller 2, the deflector conveyor roller 3, and the pinch roller 4 are rotatably supported at both ends by bearings on the bearing supports correspondingly installed on the two upright support plates 1. A driver 5 is also installed in the frame. The driver 5 is connected to the roller shafts of the cylindrical conveyor roller 2, the deflector conveyor roller 3, and the pinch roller 4 via the chain drive assembly 6 and drives the cylindrical conveyor roller 2, the deflector conveyor roller 3, and the pinch roller 4 to rotate. The cylindrical conveyor roller 2 rotates clockwise when viewed from front to back, and the deflector conveyor roller 3 and the pinch roller 4 rotate clockwise when viewed from front to back. Looking backwards, all rotations are counterclockwise; between the two upright pallets 1, on the right side of the clamping roller 4, there is also a horizontal sugarcane discharge pallet 7 with its top surface flush with the highest point of the outer circumference of the clamping roller 4; the left side between the two upright pallets 1, at the position between the corresponding upper push plate conveyor roller 3 and the cylindrical conveyor roller 2, is the sugarcane inlet; the lower side between the two upright pallets 1, at the position between the corresponding cylindrical conveyor roller 2 and the right push plate conveyor roller 3, is the sugarcane tip leaf outlet; the right side between the two upright pallets 1, at the position above the corresponding sugarcane discharge pallet 7, is the sugarcane stalk outlet.

[0018] Furthermore, the conveyor roller 3 is provided with a spindle 3.1 as a roller shaft, and multiple axially stacked rubber paddles 3.2 are sleeved in the middle of the spindle 3.1; each rubber paddle 3.2 is provided with a central disk 3.21, with a central hole for the spindle 3.1 to pass through in the center of the central disk 3.21, and a set of positioning holes for the long screw 3.3 to pass through on the periphery of the central disk 3.21; a set of radially extending fingers 3.22 are evenly distributed on the outer circumference of the central disk 3.21 and are integrated with the central disk 3.21; the positioning holes and fingers 3.22 of all axially stacked rubber paddles 3.2 are kept axially aligned. The rubber paddles 3.2 have their fingers 3.22 stacked to form multiple radially extending rubber paddles. The spindle 3.1 has end plates 3.4 fixedly connected to both ends, which press against all the axially stacked rubber paddles 3.2 from both sides. The end plates 3.4 also have through holes corresponding to the positioning holes of the rubber paddles 3.2. A long screw 3.3 passes through the through holes of the end plates 3.4 and the positioning holes of each rubber paddle 3.2, and is then screwed into a nut 3.5 for locking. This ensures that all the axially stacked rubber paddles 3.2 can only rotate synchronously with the spindle 3.1, and that the rubber paddles 3.2 cannot rotate relative to each other. Furthermore, the fingers 3.22 of the rubber paddles 3.2 have T-shaped ends to increase the friction and wear resistance of the finger ends.

[0019] Furthermore, the width of the gap between the sugarcane stalks is 20-30mm to ensure that the sugarcane leaves at the top of the sugarcane can pass through smoothly, and at the same time, to achieve a better clamping effect when clamping the connection between the sugarcane top and the sugarcane stalk.

[0020] Furthermore, the upper paddle conveyor roller 3 is located slightly to the right above the cylindrical conveyor roller 2, and the right paddle conveyor roller 3 is located slightly to the lower right of the cylindrical conveyor roller 2, so that when it forms a clamping roller with the cylindrical conveyor roller 2, it can better guide the sugarcane leaves at the top of the sugarcane for clamping, conveying and pulling.

[0021] Furthermore, the center distance between the paddle conveyor roller 3 and the cylindrical conveyor roller 2 is less than or equal to the sum of the radii of the paddle conveyor roller 3 and the cylindrical conveyor roller 2, so that the outer edge of the rubber paddle of the paddle conveyor roller 3 can brush over the outer edge of the cylindrical roller body of the cylindrical conveyor roller 2, thereby forming a stronger clamping and pulling force on the sugarcane leaves at the top of the sugarcane.

[0022] Furthermore, the gaps between the front and rear end faces of the conveyor roller 3 and the cylindrical conveyor roller 2 and the inner side of the corresponding upright support plate 1 are respectively provided with vertical baffles 8 fixedly connected to the upright support plate 1 to prevent sugarcane or sugarcane leaves from falling from both sides during the tip breaking process. The two vertical baffles 8 are provided with clearance grooves 8.1 at the positions corresponding to the clamping roller 4 and the sugarcane exit support plate 7. The two vertical baffles 8 are also provided with horn-shaped openings 8.2 that turn outward to the outside of the upright support plate 1 at the corresponding sugarcane inlet as inlet guide sections. Furthermore, the roller shafts of the push plate conveying roller 3 and the cylindrical conveying roller 2 are provided with roller shaft retaining sleeves 9 to shield the exposed portions inside the front and rear upright support plates 1. The roller shaft retaining sleeve 9 is provided with an outer retaining ring 9.1, and an inner bearing 9.2 is mounted inside the outer retaining ring 9.1. The roller shaft retaining sleeve 9 is fitted onto the corresponding roller shaft through its inner bearing 9.2. The outer retaining ring 9.1 of the roller shaft retaining sleeve 9 is fixedly engaged in the corresponding opening groove of the vertical baffle 8. When the roller shaft rotates, the outer retaining ring 9.1 of the roller shaft retaining sleeve 9 remains stationary, and the stationary outer retaining ring 9.1 shields the rotating roller shaft to prevent sugarcane leaves and other debris from getting caught in the roller shaft and causing blockage.

[0023] This sugarcane defoliation and tip trimming device operates by conveying the sugarcane from the tip first to the root. After starting the driver 5, which rotates the cylindrical conveyor roller 2, the squeegee conveyor roller 3, and the clamping roller 4, the sugarcane leaves at the tip, being soft, are first guided downwards into the clamping gap by the clamping rollers (composed of the squeegee conveyor roller 3 and the cylindrical conveyor roller 2) and the clamping roller 4. Then, the clamping rollers (composed of the squeegee conveyor roller 3 and the cylindrical conveyor roller 2) on the right pull the sugarcane leaves into the clamping gap downwards, causing them to detach and exit downwards from the tip / leaf outlet. The sugarcane continues to move to the right, and the leaves on the sugarcane stalk also move downwards in the same manner. During the defoliation process, since the sugarcane stalks are rigid and will not bend downwards into the gap between the stalks, each sugarcane stalk will automatically stop moving when the connecting joint between the sugarcane tip and the stalk body is stuck in the gap. At this time, when the convex edge 2.1 of the cylindrical conveyor roller 2 rotates to the gap, the convex edge 2.1 and the clamping roller 4 together clamp the connecting joint to complete the tip cutting. The broken tip is discharged downwards from the sugarcane tip and leaf outlet by the clamping roller composed of the right-side deflector conveyor roller 3 and the cylindrical conveyor roller 2. The sugarcane stalk after tip cutting continues to move to the right. During the movement, the sugarcane leaves on the sugarcane stalk body are torn off and removed using the same working principle. Finally, the sugarcane stalk with defoliation and tip cutting is output from the sugarcane stalk outlet.

[0024] The above illustrations are merely typical embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
