Description

Technical Field

[0001] This patent relates to a miniaturized electric sugarcane trimming and leaf-removing device, mainly used for trimming and leaf removal after sugarcane harvesting, and belongs to the technical field of small agricultural machinery automation equipment. Background Technology

[0002] Existing sugarcane trimming and leaf removal technologies, whether in step-by-step sugarcane processing systems or sugarcane combine harvesters, are all traditional, purely mechanical operation modes: the position of the sugarcane tip is not accurately judged, and it is arbitrarily broken by the amount of stress. For the sugarcane leaves attached to the surface, either nylon strips or steel wire strips are used to whip them by rapid rotation, or rubber blocks, nylon blocks, or even iron blocks are used to scrape them by rotation. The conveyor rollers rely on rotation and compression to transport multiple sugarcane stalks, resulting in high power consumption, a large and complex overall structure that is difficult to maintain, easy to damage and blockage, high cost and poor efficiency, which is unacceptable to farmers and greatly hinders the promotion of sugarcane harvesting mechanization.

[0003] From a technical perspective, this structure is problematic because purely mechanical equipment excels at processing relatively regular and uniform materials, such as rice and wheat, where the maximum and minimum particle sizes are not significantly different, resulting in uniform and standardized processing. Therefore, mechanized processing of rice and wheat has long achieved satisfactory results. However, for long, thin materials like sugarcane, purely mechanical methods are difficult to adapt to. Furthermore, the need to consider variations in thickness, length, and curvature makes this even more challenging. Using a segmented processing method leads to significant sugarcane loss, making it counterproductive, and the impurity removal rate remains high.

[0004] From a practical perspective, the aforementioned structure was introduced from abroad fifty years ago. During these fifty years, enormous human, material, and financial resources have been invested, yet the mechanization of sugarcane harvesting still falls short of satisfactory results. Therefore, whether this technological approach should continue requires careful consideration. Furthermore, issues such as hilly terrain, fragmented ownership and varying sizes of sugarcane fields, and problems with sugar mill equipment and production scheduling all comprehensively influence the final demand for sugarcane harvesting machinery. Therefore, the selection of a mechanized sugarcane harvesting technology route must be carefully considered.

[0005] The existing model only focuses on harvesting and processing efficiency. The effect of trimming and peeling leaves is far from meeting the requirements of sugar mill pressing equipment, such as whole stalk pressing and low impurity content. This is why the promotion of sugarcane harvesting mechanization has been difficult for many years. Summary of the Invention

[0006] Based on the reasons mentioned in the background technology above, the technical approach for sugarcane harvesting should first ensure the quality of the tailing and leaf stripping process, and then improve work efficiency through automation.

[0007] This patent utilizes mechatronics automatic control technology to design and invent a small electric processing device for sugarcane after harvesting. It can be flexibly placed in fields or on hand-held tractors, powered by batteries, agricultural electricity, or a small generator, to perform sugarcane trimming and leaf removal, achieving results comparable to manual methods. Furthermore, it can also be used as a unit component in large-scale automated sugarcane processing machinery.

[0008] This small electric processing device mainly includes an electric clamp with a scraper blade, a rotating clamping roller that drives the sugarcane to move back and forth, an electric tail saw, and is equipped with an intelligent controller and power system.

[0009] The clamp is equipped with photoelectric sensors to detect whether sugarcane is stuck and needs to be processed. The clamp is also equipped with aperture-type leaf scraping blades, which are controlled to retract or open via a linkage mechanism. Based on the pressure and feedback from the micro-sensor, the blades fit as closely as possible to the sugarcane surfaces of different thicknesses. While the rotating clamping rollers clamp the sugarcane and drive it to move back and forth, the blades scrape off the sugarcane leaves attached to the surface, thus completing the leaf removal process.

[0010] The electric tail saw is activated when the clamps hold the sugarcane, driving the saw blade to rotate and move while repeatedly vibrating, cutting across the clamp jaws to remove the sugarcane tail.

[0011] The significance and advantages of the electric tail-cutting and leaf-stripping device disclosed in this patent are as follows:

[0012] The sugarcane trimming and leaf stripping device uses various sensors and is intelligently controlled by an MCU. The clamps, rollers, and trimming saw work together to mimic the actions of manual sugarcane processing, achieving the same level of quality as manual processing. It has a low impurity content and consumes far less power than existing equipment.

[0013] The electric tail-cutting and leaf-removing device is highly efficient and intelligently senses the working status. It saves energy when not in use and starts up quickly once sugarcane is placed in it. The entire device can automatically complete the tail-cutting and leaf-removing process by simply placing the cut sugarcane onto the clamps, replacing heavy manual labor, reducing labor intensity, and saving sugarcane farmers time and effort.

[0014] The entire device is small in size and lightweight, easy to carry, simple to use and low in cost, and easy to maintain, making it affordable for sugarcane farmers.

[0015] The sugarcane trimming and leaf stripping device itself has an MCU. By adding a 4G / 5G communication module with Beidou positioning, it can transmit information such as the quantity, time and location of sugarcane processing to the cloud server in real time. The transmitted data can be as detailed as how many seconds it takes to process a sugarcane, how long the sugarcane is, which field the whole set of equipment is located in, and whether the equipment is operating normally. This greatly facilitates the production scheduling of raw sugarcane in sugar factories and the monitoring and information collection of raw sugarcane production by relevant departments such as sugar industry management platforms. It brings sugarcane harvesting from the era of traditional manual agriculture to the era of intelligent big data in one step. Attached Figure Description

[0022] This patent describes a small electric tail-trimming and leaf-stripping device, comprising an electric clamp (1), a photoelectric sensing module (2), a rotating clamping roller (4), an electric tail-trimming saw (3), and a support base (5). A pair of rotating clamping rollers (4) are installed at the upper center of the support base (5). An electric clamp (1) is installed on each of the front and rear sides of the rotating clamping rollers (4). An electric tail-trimming saw is installed on the side of the support base (5) adjacent to the rear electric clamp (1). The clamping jaws of the two electric clamps (1) and the middle position of the pair of rotating clamping rollers (4) form a central axis channel for placing sugarcane (6). The photoelectric sensing module (2) is installed at the top of the inside of the clamp bracket (103) to detect whether there is sugarcane blocking the middle of the clamp. After the sugarcane (6) is placed in, the two electric clamps (1) each close their clamp arms (102) so that multiple leaf scraping blades (101) together hold the sugarcane (6). The electric tail saw (3) then cuts off the sugarcane tail. A pair of rotating clamping rollers (4) close and clamp the sugarcane (6) and rotate, causing the sugarcane (6) to scrape back and forth on the blade of the leaf scraping blade (101) of the electric clamp (1) to remove the sugarcane leaves attached to the surface of the sugarcane.

[0023] In the tail-shaving and leaf-stripping device, the electric clamp (1) consists of a leaf-scraping blade (101), a clamp arm (102), a clamp bracket (103), a linkage mechanism (104), and an electromechanical drive control chamber (105). The clamp bracket (103) is fixed at the upper end of the electromechanical drive control chamber (105). The clamp arm (102) is installed on various rotating shafts of the clamp bracket (103). The front end of the clamp arm (102) is equipped with a leaf-scraping blade (101), and the tail end is connected to the linkage mechanism (104). The drive shaft of the linkage mechanism (104) extends into the electromechanical drive control chamber (105). The electromechanical drive control chamber (105) contains a drive motor and a control circuit, which are used to control the opening and closing of the drive clamp arm (102).

[0024] In the tail-cutting and leaf-removing device, the electric tail-cutting saw (3) consists of a saw blade (301), a saw blade motor bracket (302), a drive motor (303), and a bracket rotation mechanism (304). The drive motor (303) drives the saw blade (301) to repeatedly vibrate and perform cutting actions.
