Abstract
Description
A smart sugarcane cleaning machine Technical Field
[0001] This invention relates to the field of agricultural machinery and equipment technology, and in particular to an intelligent sugarcane cleaning machine. Background Technology
[0002] The inventors are aware of several technical problems with sugarcane harvesters, including: the inability to quickly and evenly separate and transport the piled sugarcane with leaves to the leaf stripping and impurity removal mechanism; the predominantly used sugarcane harvester, both domestically and internationally, is a cutting-type harvester. This method involves cutting the sugarcane into small sections and then using a blower to remove the leaves and debris. This results in many cut fragments being blown away by the blower, and the machine's heavy weight makes it prone to crushing the sugarcane root, leading to high loss rates, broken ends, and impurity content. In whole-stalk stripping and impurity removal equipment, the sugarcane enters a high-speed roller for stripping and impurity removal, and the repeated impacts and friction as it passes through the roller channel easily cause breakage, damage, and other losses. When sugarcane with leaves directly enters the leaf stripping and impurity removal mechanism, the sugarcane tail cannot be cut off as required. The excessive and long leaves at the tail easily entangle the stripping and impurity removal mechanism, affecting production and failing to meet the requirements of sugar mills and sugarcane cultivation. Summary of the Invention

Detailed Implementation
[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] The purpose of this invention is to provide an intelligent sugarcane impurity removal machine to solve the problems existing in the prior art, which can cut off the sugarcane tail, reduce the impurity rate of the yield, and improve the quality of sugarcane harvest.
[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] This invention provides a sugarcane intelligent impurity removal machine 100, as shown in Figures 1-4. It includes a machine body and a sorting mechanism, a conveying mechanism 3, a leaf stripping and impurity removal mechanism 4, a crushing mechanism 5, and a carriage 7, all mounted on the machine body. It also includes a robotic arm 9 and a tail-cutting mechanism 8 mounted on the machine body. The tail-cutting mechanism 8 includes a vibrating platform 81 mounted above the crushing mechanism 5, a baffle fixedly mounted above the vibrating platform 81, and a tail-cutting gripping base 82 mounted above the baffle. The vibrating platform 81 is hollow in the middle, and the baffle is detachable. The tail-cutting gripping base 82 forms an accommodating space inside, into which the robotic arm 9 can vertically place the sugarcane. The tail-cutting gripping base 82 has a slide 85 for inserting a chainsaw, which can be used to cut off the sugarcane tail.
[0026] The intelligent sugarcane cleaning machine provided by this invention has the following working process: Sugarcane is cut down and placed on the field ground by a sugarcane cutter or manually. First, it is picked up by a robotic arm 9, then the sugarcane is inverted with the tail facing down and placed vertically into the receiving space of the tail-cutting grab base 82. The sugarcane tail can abut against the baffle. After vibration by the vibration platform 81, the sugarcane tail is automatically aligned. Then, the position where the tail needs to be cut is selected and sawn with a chainsaw. Then, the baffle is opened, and the sugarcane tail falls into the crushing mechanism 5 for crushing. The crushed sugarcane tail is transported out by the conveying mechanism 3 and packaged. The sugarcane after tail cutting is then quickly transported by the conveying mechanism 3 to the leaf-peeling and cleaning mechanism 4 for forward and reverse leaf-peeling and cleaning. With the leaf-peeling brush rotating back and forth and rubbing against the sugarcane, the whole-stalk sugarcane leaf-peeling and cleaning operation is completed, avoiding damage, breakage or head breakage caused by sugarcane impact, and reducing losses. During the transportation process, the sugarcane is evenly sorted by the sorting mechanism. After the leaf-peeling and cleaning is completed, the sugarcane is sent into the carriage 7 to complete the operation. The intelligent sugarcane impurity removal machine 100 provided by this invention can significantly reduce the impurity rate during harvesting, improve the quality and efficiency of sugarcane mechanical harvesting, truly solve the pain points of mechanized harvesting in the industry, increase the economic benefits of sugarcane growers and sugar mills, and can also be applied to the harvesting of root crops such as forage grass and mulberry trees, with a wide range of applications.
[0027] In some embodiments, the machine body includes a tracked chassis 1, a rotating mechanism 2 fixedly mounted on the tracked chassis 1, a bracket fixedly mounted on the output end of the rotating mechanism 2, and a cab 6 fixedly mounted on the bracket. The sorting mechanism, conveying mechanism 3, leaf stripping and impurity removal mechanism 4, robotic arm 9, tail-cutting gripper base 82, and crushing mechanism 5 are all mounted on the bracket. By setting the rotating mechanism 2, sugarcane can be transported laterally and obliquely to the truck bed 7, realizing the functions of leaf stripping and impurity removal and sugarcane feeding. After the sugarcane impurity removal operation reaches the end of the field, the cab 6 can rotate 180 degrees to turn around, reducing damage to the sugarcane roots. Since the fully suspended bracket is 800mm wide, it can be rotated to change the position of the extra-wide bracket on ordinary roads to prevent affecting vehicle traffic. The right side plate of the bracket can be designed as a folding and telescopic form to avoid collision with the equipment in front of the cab 6 when the suspended bracket rotates.
[0028] The rotating mechanism 2 is a slewing bearing that supports the upper structure of the intelligent sugarcane cleaner and allows it to rotate freely. It can maintain stable rotation while bearing huge loads. The intelligent sugarcane cleaner 100 has a braking system that can ensure that the support is stably kept in a specific direction or stop rotating. This is achieved by locking the output of the hydraulic motor to prevent the structure from rotating under external force. This design allows the intelligent sugarcane cleaner 100 to flexibly adjust its working direction on the work site and can work on different areas without moving the entire machine body, which greatly improves the work efficiency and flexibility. At the same time, the 360° rotation capability also allows the intelligent sugarcane cleaner 100 to work in compact spaces, improving work efficiency.
[0029] The rotating mechanism 2 can rotate 180° to reverse the conveying direction of the sugarcane. The leaf-removing and impurity-removing mechanism 4 is equipped with leaf-brushing and impurity-removing rubber strips. Through cyclic rotation, the sugarcane is rubbed to avoid breakage, damage or head breakage, thus achieving the effect of leaf removal and impurity removal. The sorting mechanism, conveying mechanism 3, leaf-removing and impurity-removing mechanism 4, crushing mechanism 5 and rotating mechanism 2 can all be implemented using existing technologies.
[0030] In some embodiments, the tail-cutting gripper base 82 includes a base 83 fixedly mounted on a support and a lifting seat 84 movably mounted on the support. The bottom of the lifting seat 84 is provided with a slide rail 85. In the initial state, the lifting seat 84 is located outside the base 83 to save space. During operation, because the height of the base 83 is insufficient, it cannot stably clamp the sugarcane. By moving the lifting seat 84 above the base 83 and cooperating with the base 83, the sugarcane can be stably clamped.
[0031] In some embodiments, the support is provided with a lifting cylinder 86 that can push the lifting seat 84 to rise and fall, and an inner push cylinder 87 that can push the lifting seat 84 to clamp the sugarcane. When the lifting cylinder 86 lifts the lifting seat 84 to a position higher than the base 83, it stops operating. Then, the inner push cylinder 87 pushes the two clamping units of the lifting seat 84, which can move the lifting seat 84 above the base 83 and align it with the base 83.
[0032] In some embodiments, both the base 83 and the lifting seat 84 include two corresponding clamping units. The two clamping units cooperate to clamp the sugarcane. Each clamping unit includes an outer cylinder and an inner cylinder. The outer wall of the inner cylinder and the inner wall of the outer cylinder are fixedly connected by a spring. The tightness of the clamping of the sugarcane by the base 83 and the lifting seat 84 can be changed by adjusting the spring.
[0033] In some embodiments, the top of the lifting seat 84 is provided with a flared opening to facilitate the insertion of sugarcane.
[0034] In some embodiments, the robotic arm 9 includes a support base 91 rotatably connected to a bracket, a connecting rod 92 rotatably connected at one end to the support base 91, and a gripper 93 rotatably connected to the other end of the connecting rod 92. The support base 91, the connecting rod 92, and the gripper 93 are all driven by a hydraulic motor to realize the rotation of the support base 91, the connecting rod 92, or the gripper 93 and the gripping action of the gripper 93.
[0035] In some embodiments, the gripper 93 includes two outer claws, and an inner claw is provided on each side of the two outer claws that are close to each other. The outer claws and the inner claws are fixedly connected by a spring. The gripper 93 can change the tightness of its grip on the sugarcane by adjusting the spring.
[0036] In some embodiments, the vibration platform 81 is provided with a slot, and the baffle can be snapped into the slot, which facilitates the installation and removal of the baffle. The baffle can also be fixed to the vibration platform 81 by screws.
[0037] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
