Description

Technical Field

[0001] This utility model relates to the field of sugarcane harvesting and planting machinery technology, specifically a sugarcane harvesting and planting machine that can harvest and plant sugarcane. Background Technology

[0002] Sugarcane is the main raw material for sugar production. It contains not only a large amount of sugar and water, but also various vitamins and other organic substances that promote human metabolism, making it an important crop. Although my country is a major sugarcane producer, the high labor costs and low level of mechanization in sugarcane planting and harvesting significantly limit the development of the sugar industry.

[0003] Currently, sugarcane cultivation mainly faces the following technical bottlenecks: 1. Sugarcane harvesters and planters are independent pieces of equipment, such as the 4GZQ-260 pure harvester and the 2CZX-2 planter. Switching between processes requires changing the implements, resulting in an equipment idle rate of over 40% and a reduction in overall efficiency of approximately 35%. 2. In traditional methods, harvesting and planting cannot be carried out simultaneously. The harvester must work first, followed by manual or planting machine work for tasks such as ditching, seeding, and soil covering. This method involves a large travel distance for the tracked walking mechanism, resulting in a long total working time and is not conducive to energy conservation and consumption reduction.

[0004] Based on the above problems, it is necessary to propose a sugarcane harvesting and planting machine that can simultaneously harvest and plant sugarcane, reduce the travel distance during the planting and harvesting process, avoid repeated switching of equipment during the planting and harvesting process, improve production efficiency, and promote the mechanization of sugarcane planting and harvesting. Utility Model Content

[0005] This invention provides a sugarcane harvesting and planting machine that can simultaneously harvest and plant sugarcane, and can reduce the problem of repeated switching of machinery during the harvesting and planting process, which helps to simplify sugarcane harvesting and planting operations and improve production efficiency.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model solves the above-mentioned problems through the following technical solution:

[0007] A sugarcane harvester capable of both harvesting and planting includes a tracked walking mechanism and a main mounting frame mounted thereon. A harvesting device and a planting device are mounted on the main mounting frame. The harvesting device includes a harvester frame, a harvesting blade assembly, a tilting conveyor mechanism, a cutting mechanism, a stalk collection box, and collection claws. The harvester frame is mounted on the main mounting frame, with a sugarcane inlet at the front end. Collection claws are located at the front end of the sugarcane inlet to guide the sugarcane in. The tilting conveyor mechanism and the harvesting blade assembly are located on the upper and lower sides of the sugarcane inlet. The stalk collection box is located behind the tilting conveyor mechanism to receive the output sugarcane. The tilting conveyor mechanism includes a pair of vertical rollers mounted on both sides of the sugarcane inlet, and a pair of horizontal rollers arranged vertically behind the vertical rollers. Each vertical roller is connected to a corresponding horizontal roller via a conveyor belt, forming a belt conveyor structure that rotates the sugarcane 90 degrees. The cutting mechanism includes a set of longitudinal cutters symmetrically arranged on both sides of the front of the horizontal rollers. The horizontal rollers and longitudinal cutters are powered by a transmission motor via a gear transmission mechanism.

[0008] The planting device includes a planting frame fixed to the side of the main mounting frame. From front to back, the lower part of the planting frame is equipped with a furrow opener, a straightening wheel, and a soil covering plate. The upper part of the planting frame is equipped with a seed storage and feeding mechanism, and the discharge end of the seed storage and feeding mechanism points to the working position of the straightening wheel.

[0009] In this design, the harvesting device is located in the middle of the machine. The target sugarcane enters the harvesting device through the sugarcane inlet, and a flipping conveyor flips the sugarcane into a transverse position before it enters the cutting mechanism. The cutting mechanism cuts off the sugarcane stalks and sends them to the stalk collection box to obtain the harvested sugarcane. This structure produces neatly stacked sugarcane of uniform length, resulting in high product consistency. The planting device is installed on one side of the harvesting device and can sequentially perform furrowing, sowing, and covering operations. This design integrates the harvesting and planting devices into the same machine, allowing for the simultaneous selection of one or more operations as needed, reducing the machine's travel distance during harvesting and planting, and improving harvesting efficiency.

[0010] Furthermore, a lateral adjustment mechanism is installed on both sides of the conveyor belt. The lateral adjustment mechanism includes an adjustment belt arranged on the left and right, a main adjustment roller and a slave adjustment roller that drive the adjustment belt, and is equipped with a vision recognition module to identify sugarcane nodes. The image acquisition end of the vision recognition module is pointed to the area to be cut in front of the longitudinal cutter. The main control device receives the signal from the vision recognition module to control the adjustment motor to work.

[0011] Furthermore, the seed storage and feeding mechanism includes a storage box installed vertically and a segmented conveying mechanism. The segmented conveying mechanism includes a segmented conveying track and a feeding motor that drives the segmented conveying track for transportation. The segmented conveying track has a segmented grid array on its surface, and its feeding end is longitudinally aligned with the working position of the straightening wheel.

[0012] Furthermore, the harvesting blade assembly includes a pair of transverse rotating blades arranged on the left and right sides, the gap between the two transverse rotating blades corresponding to the longitudinal direction of the sugarcane inlet, the transverse rotating blades being driven by a harvesting motor, and the harvesting motor being mounted on the walking frame of the tracked walking mechanism via a connecting frame.

[0013] Furthermore, a rootstock collection device is provided behind the harvesting device. The rootstock collection device includes a rootstock collection box located behind the stem collection box, a gantry frame erected above the rootstock collection box, and an actuation mechanism that slides back and forth along the gantry frame. The actuation mechanism includes an X-axis displacement assembly and a Z-axis displacement assembly stacked sequentially on the gantry frame, and a gripping assembly installed at the working end of the Z-axis displacement assembly. The gripping assembly includes a gripper base and a gripper motor. The gripper motor drives the gripper gear to rotate. The upper and lower ends of the gripper gear symmetrically mesh with the gripper drive rack. Grippers are installed on the gripper drive rack to form a gripping structure.

[0014] Furthermore, the Z-axis displacement component includes two sets of electric hoist structures symmetrically arranged front and rear. Each electric hoist structure includes a drive motor, a drum, and a wire rope. The bottom end of the wire rope is connected to a gripper seat to drive the gripping component to rise and fall.

[0015] Furthermore, a plastic film roll support is installed on the rear side of the planting machine frame; the furrow opener, straightening wheel, and soil covering plate have longitudinally arranged mounting holes on their upper parts and are installed on the planting machine frame by threaded fasteners.

[0016] The advantages and effects of this utility model are:

[0017] 1. The sugarcane harvesting and planting machine proposed in this utility model integrates a harvesting device and a planting device, so that the harvesting and planting functions can be carried out simultaneously, which helps to reduce the machine's travel distance during the harvesting and planting process and improve the harvesting and planting efficiency.

[0018] 2. In the solution, the harvesting device can transform vertical sugarcane stalks of varying lengths into horizontal sugarcane stalks of equal length, and collect them into a stalk collection box, thereby realizing automated harvesting and sorting of sugarcane and obtaining harvested products with high consistency.

[0019] 3. In this scheme, the segmented conveyor mechanism of the planting device adopts a segmented conveyor belt. The belt surface array of the segmented conveyor belt is set with segmented grids. Each segment can just accommodate one sugarcane seed. Under the control of the feeding motor, the sugarcane seed can be evenly dropped into the soil through the straightening wheel. Reasonable dense planting is conducive to improving the germination rate.

[0020] 4. This plan is equipped with a root collection device, which can collect and process the root residues left after harvesting by the harvesting device, which helps to reduce the impact of root residues on the following year's yield and reduce the occurrence of pests and diseases.

[0029] The present invention will be further described below with reference to the embodiments, but the present invention is not limited to these embodiments.

[0030] This embodiment describes a sugarcane harvester that can both harvest and plant sugarcane, as shown in the attached figure. Figure 1 , 2 As shown, its main body includes a tracked walking mechanism 1, a main mounting frame 2, a harvesting device 3, a planting device 4, a rhizome collection device 5, and a main control device 6. The main mounting frame 2 is mounted on the tracked walking mechanism 1. The harvesting device 3 and the rhizome collection device 5 are mounted at the top center of the main mounting frame 2, respectively. The planting device 4 is mounted on the right side of the harvesting device 3. The main control device 6 is mounted on the walking frame of the tracked walking mechanism 1.

[0031] As attached Figure 1 , 2 As shown in Figure 3, the harvesting device 3 includes a harvester frame 31, a harvester blade assembly 32, a stalk collection box 35, and a tilting conveyor mechanism 33, a cutting mechanism 34, a gear transmission mechanism 36, a conveyor motor 37, a lateral adjustment mechanism 38, and a collection claw 39 mounted on the harvester frame 31. A sugarcane inlet is opened at the front end of the harvester frame 31 for the sugarcane to pass longitudinally. The collection claw 39 includes a pair of arc-shaped guide plates symmetrically arranged on both sides of the front end of the sugarcane inlet, which guide the sugarcane towards the center to enter the sugarcane inlet. The tilting conveyor mechanism 33 and the harvester blade assembly 32 are respectively located on the upper and lower sides of the sugarcane inlet. The stalk collection box 35 is located behind the tilting conveyor mechanism 33 to receive the output sugarcane and is fixed to the main mounting frame 2.

[0032] The harvester blade assembly 32 includes a pair of transverse rotating blades 321 arranged on the left and right. The gap between the two transverse rotating blades 321 corresponds to the longitudinal direction of the sugarcane inlet. The transverse rotating blades 321 are driven by a harvester motor 322. The harvester motor 322 is mounted on the walking frame of the tracked walking mechanism 1 through a connecting frame and is connected to the main control device 6 by wiring.

[0033] The flipping conveyor mechanism 33 includes a pair of vertical rollers 331 mounted on both sides of the sugarcane inlet, and a pair of horizontal rollers 332 arranged vertically behind the vertical rollers 331. Each vertical roller 331 is connected to a horizontal roller 332 via a conveyor belt 333, forming a belt conveyor structure that allows the sugarcane to rotate 90 degrees. Two gear transmission mechanisms 36 are located on both sides of the harvester frame 31. The two horizontal rollers 332 are linked through the gear transmission mechanisms 36, with the horizontal rollers 332 acting as the driving rollers. One side of the gear transmission mechanism 36 is connected to a conveyor motor 37 to obtain rotational power.

[0034] The cutting mechanism 34 includes a set of longitudinal cutting blades 341 symmetrically arranged on both sides of the front of the horizontal roller 332. The longitudinal cutting blades 341 are linked to the horizontal roller 332 through the same set of gear transmission mechanism 36 and are powered by the same transmission motor 37. Through the configuration of the gear ratio, the speed coordination of the longitudinal cutting blades 341 and the transverse rotating blades 321 can be achieved.

[0035] Two lateral adjustment mechanisms 38 are located on both sides of the conveyor belt 333, with their working positions positioned in front of the working positions of the harvester assembly 32.

The main adjusting roller 382 is connected to the output of an adjusting motor 384, and the adjusting motor 384 is connected to the main control device 6. A visual recognition module 385 is also included for identifying sugarcane nodes. The visual recognition module 385 includes an image acquisition device (such as a camera) and an image processing unit. The image acquisition end of the image acquisition device points towards the cutting position in front of the longitudinal cutter 341. The visual recognition module 385 is connected to the main control device 6 via signals.

[0036] As attached Figure 4 As shown, the planting device 4 includes a planting frame 41, a furrow opener 42, a straightening wheel 43, a soil covering tray 44, a storage bin 45, a segmented conveying mechanism 46, and a plastic film roll support 47. The planting frame 41 is fixed to the side of the main mounting frame 2. The furrow opener 42, the straightening wheel 43, and the soil covering tray 44 are installed sequentially from front to back on the lower part of the planting frame 41. The upper part of the straightening wheel 43 and the soil covering tray 44 has longitudinally arranged mounting holes, and they are fixed to the planting frame 41 by selecting appropriate mounting holes with threaded fasteners. The plastic film roll support 47 is installed on the rear side of the planting frame 41. The seed storage and dispensing mechanism, consisting of the storage bin 45 and the segmented conveying mechanism 46, is installed on the upper part of the planting frame 41, and the discharge end of the seed storage and dispensing mechanism points to the working position of the straightening wheel 43.

[0037] The storage bin 45 and the segmented conveyor mechanism 46 are mounted vertically on the planting frame 41. Seeds from the storage bin 45 fall into the segmented conveyor belt 461 of the segmented conveyor mechanism 46. The belt surface of the segmented conveyor belt 461 is equipped with segmented grids. The conveyor wheels of the segmented conveyor belt 461 are driven by the feeding motor 462. The feeding end of the segmented conveyor belt 461 is longitudinally aligned with the working position of the straightening wheel 43. The falling seeds are guided by the straightening wheel 43 to fall into the target sowing position.

[0038] As attached Figure 5 As shown, the perennial root collection device 5 includes a perennial root collection box 51, a gantry frame 52, an X-axis displacement assembly 53, a Z-axis displacement assembly 54, and a clamping assembly 55. The perennial root collection box 51 is installed on the main mounting frame 2 behind the stem collection box 35. The gantry frame 52 is fixed to the main mounting frame 2 and erected above the perennial root collection box 51. The X-axis displacement assembly 53 is a linear movement module installed on the gantry frame 52 in the front-to-back direction. The Z-axis displacement assembly 54 consists of two sets of electric hoist structures symmetrically arranged in the front and back of the sliding part of the X-axis displacement assembly 53. The electric hoist structure includes a drive motor 541, a drum 542, and a wire rope 543. The bottom end of the wire rope 543 is connected to a gripper seat 551, which drives the clamping assembly 55 to rise and fall.

[0039] The gripping assembly 55 includes a gripper base 551 and a gripper motor 552. The gripper motor 552 drives the gripper gear to rotate. The upper and lower ends of the gripper gear symmetrically mesh with the gripper drive rack 553. Grippers 554 are mounted on the gripper drive rack 553 to form a gripping structure. The rotation of the gripper gear synchronously drives the two gripper drive racks 553 to move. Adjusting the relative displacement of the grippers 554 adjusts the gripping and releasing action.

[0040] The sugarcane harvester described in this embodiment, which can both harvest and plant, includes the following steps:

[0041] 1. Before starting work, fill the sugarcane seed into the storage box 45, adjust the furrow opener 42, straightening wheel 43, and soil covering plate 44 to a suitable height, and install the plastic film roll on the plastic film roll bracket 47.

[0042] 2. Start the tracked walking mechanism 1, harvesting device 3, planting device 4, and ratoon collection device 5. The tracked walking mechanism 1 moves forward at a set speed. The collecting claw 39 guides the sugarcane into the sugarcane inlet. The harvesting knife group 32 cuts off the lower part of the sugarcane. The sugarcane stalks enter the flipping conveyor mechanism 33 and are changed from vertical to horizontal by the conveyor belt 333.

[0043] 3. During the laterally transported sugarcane, the visual recognition module 1-13 identifies and judges whether the sugarcane node is located in the same longitudinal plane as the longitudinal cutter 341 of the cutting mechanism 34. If they are in the same longitudinal plane, the lateral adjustment mechanism 38 is activated to translate and adjust the position of the sugarcane stalk to be out of the same plane. The movement direction of the lateral adjustment mechanisms 38 on both sides is the same. When the sugarcane nodes on both sides are not in the same longitudinal plane as the longitudinal cutter 341, the lateral adjustment mechanism 38 is not activated.

[0044] 4. The sugarcane is transported to the longitudinal cutter 341 working position of the cutting mechanism 34. The longitudinal cutter 341 cuts the sugarcane into a fixed length, and then falls into the stalk collection box 51 through the gap of the horizontal roller 332, completing the sorting and storage of the stalks.

[0045] 5. While the harvesting device 3 is working, the stalk collection device 5 is also in operation. The Z-axis displacement component 54 is activated, causing the gripping component 55 to descend to the height corresponding to the sugarcane stalk above the stalk. The gripper motor 552 is activated to grip the sugarcane stalk. The Z-axis displacement component 54 is activated, causing the gripping component 55 to rise to the initial height. Then, the X-axis displacement component is activated, moving the gripped stalk above the stalk collection box 51. The gripper motor 552 reverses to release the stalk, and the stalk falls into the stalk collection box 51. Then, the X-axis displacement component drives the gripping component 55 back to its original position, and the gripping operation is repeated.

[0046] 6. While the harvesting device 3 is working, the planting device 4 is also in operation. The furrow opener 42 opens furrows suitable for the sugarcane planting depth. Sugarcane seeds fall from the storage box 45 into the grid conveyor belt 461. Each grid can only hold one sugarcane seed. The sugarcane seeds are conveyed by the grid conveyor belt 461 and fall onto the straightening wheel 43 in sequence. After being straightened by the straightening wheel 43, they fall into the soil evenly with a certain spacing. Then, the covering plate 44 covers the soil. Finally, the mulch film roll on the mulch film roll bracket 47 covers the land with the seed harvester to complete the mulching, thus completing the planting part.

[0047] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations of these embodiments without departing from the principles and spirit of this utility model still fall within the protection scope of this utility model.
