Description

Technical Field

[0001] The invention relates to the technical field of sugarcane harvesting, in particular to a vertical whole-stalk sugarcane combine harvester. Background Art

[0002] Sugarcane is a temperate and tropical crop that is the raw material for making sugar and can be used to extract ethanol as an energy alternative.

[0003] At present, there are two main types of sugarcane combine harvesters at home and abroad: segmented type and whole-stem type. When harvesting sugarcane, the segmented sugarcane harvester cuts the whole sugarcane into small segments of equal length. This type of harvesting process is relatively simple, but because the sugarcane is cut into segments during harvesting, there are many cuts, which is not conducive to the preservation of raw sugarcane. During the preservation process, the sugarcane is prone to loss due to deterioration. This type of machine is large and not suitable for small plots of land. It is also expensive, so it is not conducive to large-scale application in my country's sugarcane planting areas. The whole-stem sugarcane combine harvester is large in size. Now large sugarcane bases generally use whole-stem sugarcane combine harvesters for rapid and large-scale harvesting. However, ordinary harvesters only have harvesting functions but no leaf stripping functions. Some harvesters with leaf stripping functions have low leaf stripping efficiency, which affects the normal work of the harvester, making it difficult to promote sugarcane harvesters with leaf stripping functions.

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a vertical entry type whole-stem sugarcane combine harvester, comprising a harvester body 10 with a driving cabin 101, a mounting bracket 102 is provided at the front side of the harvester body 10, the mounting bracket 102 is provided with a sugarcane harvesting mechanism 20 for cutting sugarcane, two groups of sugarcane lifting conveyor belts 30 intersecting with the sugarcane harvesting mechanism 20 and used for conveying sugarcane, and a leaf stripping conveying mechanism 40 intersecting with the discharge ends of the two groups of sugarcane lifting conveyor belts 30, a side-falling silo 50 intersecting with the output end of the leaf stripping conveying mechanism 40 and a hydraulic power system 51 for pushing the side-falling silo 50 to sideways and discharge the sugarcane are provided at the rear side of the harvester body 10, The hydraulic power system 51 is arranged between the side-falling material bin 50 and the harvester body 10, so that when the hydraulic power system 51 is started, the side-falling material bin 50 can be pushed to fall sideways; the front side of the sugarcane harvesting mechanism 20 is provided with a front gathering component 60 for gathering sugarcane and pushing the sugarcane to the sugarcane harvesting mechanism 20 for cutting; the top of the driving cabin 101 is provided with a topping disc component 70 for cutting the top leaves of the sugarcane, and a PLC control device is provided in the driving cabin 101, and the operation of the sugarcane harvesting mechanism 20, two sets of sugarcane lifting conveyor belts 30, the leaf stripping conveying mechanism 40, the front gathering component 60 and the topping disc component 70 are controlled by the PLC control device.

[0027] During operation, the harvester body 10 is started to move forward. When the front gathering component 60 moves to the sugarcane, the front gathering component 60 gathers the sugarcane and pushes the sugarcane to the sugarcane harvesting mechanism 20 for cutting. The cut sugarcane is moved to the two groups of sugarcane lifting conveyor belts 30, and the two groups of sugarcane lifting conveyor belts 30 convey the sugarcane to the leaf stripping conveying mechanism 40. At the same time, in the process of the two groups of sugarcane lifting conveyor belts 30 conveying the sugarcane, the topping cutter disc assembly 70 on the top of the driving cabin 101 tops the sugarcane and cuts off the sugarcane leaves on the top of the sugarcane, and the whole sugarcane is stripped by the leaf stripping conveying mechanism 40. The stripped sugarcane flows into the side-falling silo 50 through the leaf stripping conveying mechanism 40 for storage. When the side-falling silo 50 is full, the hydraulic power system 51 is started, and the side-falling silo 50 is pushed to tilt toward one side of the harvester body 10 by the hydraulic power system 51, and the sugarcane is poured onto the predetermined equipment or the ground.

[0028] In addition, in order to prevent the sugarcane from tipping over during cutting, to prevent the sugarcane harvesting mechanism 20 from being unable to cut the sugarcane and the sugarcane lifting conveyor belt 30 from transporting the sugarcane, a straightening guide link 80 is provided on the front side of the harvester body 10 for straightening the sugarcane and guiding the sugarcane from the front gathering component 60 to the leaf stripping conveying mechanism 40. The straightening guide link 80 is fixed to the front gathering component 60, the top cutting blade assembly 70, the front side of the harvester body 10 and the leaf stripping conveying mechanism 40 in sequence. The straightening guide link 80 can prevent the cut sugarcane from tipping over and being crushed by the harvester body 10, thereby improving the efficiency of harvesting sugarcane.

[0029] For further information, see Figure 4 The front gathering component 60 is mainly used to move and gather sugarcane, and includes two triangularly arranged conveying racks 61. The conveying racks 61 are symmetrically hinged on the mounting bracket 102 on the front side of the sugarcane harvesting mechanism 20. The mounting bracket 102 is provided with a driving cylinder 610 for driving the conveying rack 61 to rise and fall. The conveying rack 61 can be lifted by the driving cylinder 610. When sugarcane is not harvested, the conveying rack 61 can be lifted to prevent the conveying rack 61 from colliding with the high bottom surface when the harvester body 10 is started. The two symmetrically arranged conveying racks 61 form a U-shaped clip. The conveyor frame 61 is in the shape of a U-shaped conveyor frame 61, and a transmission shaft group with gears is provided on the transmission shaft group. A chain 62 is connected to the transmission shaft group. A shifting block 63 for shifting the sugarcane is installed on the chain 62. The conveyor frame 61 is also provided with a first driving motor 64 that drives the transmission shaft group to rotate. When working, the first driving motor 64 drives the chain 62 to rotate, and the sugarcane is shifted by the shifting block 63 to move between the two U-shaped conveyor frames 61. The shifting block 63 shifts the sugarcane toward the sugarcane harvesting mechanism 20. The front folding component 60 is provided to ensure that the sugarcane harvesting mechanism 20 effectively cuts the sugarcane.

[0030] Also, see Figure 3In order to enable the sugarcane moved by the front gathering component 60 to be transferred toward the sugarcane harvesting mechanism 20 and the cut sugarcane to be transferred toward the two groups of sugarcane lifting conveyor belts 30, an active sugarcane gathering disc 103 and a driven sugarcane gathering disc 104 for gathering and sending sugarcane are provided on the mounting bracket 102 located between the front gathering component 60 and the sugarcane harvesting mechanism 20. There are two driven active sugarcane gathering discs 103, which are arranged up and down. The two active sugarcane gathering discs 103 are connected by a rotating shaft, and a third driving motor for driving the rotating shaft to rotate is provided on the mounting bracket 102. The rotating shaft is driven to rotate by the third driving motor, so that the active sugarcane gathering disc 103 rotates to drive the sugarcane to move. The sugarcane in the moving process also drives the driven sugarcane gathering disc 104 to rotate, so that the sugarcane is orderly transported to the sugarcane harvesting mechanism 20 for cutting and the cut sugarcane is transported to the sugarcane lifting conveyor belt 30.

[0031] For details, please refer to Figure 5 The sugarcane harvesting mechanism 20 includes a mounting plate 21 with a guide rail, a first driving motor 22 is slidably mounted on the mounting plate 21, a knife disc 23 with a plurality of cutting knives is provided at the output end of the first driving motor 22, and a first pushing device 24 is connected to the output end of the mounting plate 21 and used to drive the first driving motor 22 to move up and down along the guide rail. The height of the knife disc 23 and the ground can be adjusted by the first pushing device 24, so that the sugarcane can be effectively cut to avoid cutting too high and wasting resources;

[0032] In addition, in order to ensure that the knife disc 23 maintains the same height as the ground on the uneven ground, the sugarcane harvesting mechanism 20 also includes a ground height detection component for adjusting the height of the knife disc 23 and the ground. The ground height detection component is provided with a connecting plate 25 installed on the mounting bracket 102, and a roller connecting rod 26 is hinged on the mounting bracket 102 away from the connecting plate 25. A height measuring guide wheel 27 is rotatably installed at the end of the roller connecting rod 26. The ground height detection component is also provided with a roller connecting rod 26 hinged at the end of the roller connecting rod 26 and used to push the roller connecting rod 26 to move up and down. The top of the rocker arm 28 is hinged with a vertically arranged lifting link 280, and the lifting link 280 is slidably installed on the connecting plate 25. A rack is provided on the lifting link 280, and an encoder for calculating the up and down movement distance of the rack and electrically connected to the PLC control device is provided on the connecting plate 25 on the side of the rack. The PLC control device receives the signal of the encoder to control the first pushing device 24 to adjust the height of the cutter disc 23. A second pushing device 29 with an output end connected to the lifting link 280 is also provided on the connecting plate 25 on the side of the lifting link 280. During operation, the height of the sugarcane ridge is preset in the PLC control device first, so that the second pushing device 29 pushes the lifting connecting rod 280 to move, and the rocker arm 28 pushes the height measuring guide wheel 27 to press against the ground. After the height measuring guide wheel 27 presses against the ground, the second pushing device 29 stops, and the encoder calculates the rack height at this position as the origin. When the height measuring guide wheel 27 moves to the undulating bottom surface, the roller connecting rod 26 connected to the height measuring guide wheel 27 pushes the rocker arm 28 to move, and then the rocker arm 28 pushes the rack connected to the lifting connecting rod 280 to move. The encoder calculates the distance the gear moves, and the encoder feeds back the detected data to the PLC control device, which controls the first pushing device 24 to push the cutter disc 23, and then adjusts the height of the cutter disc 23 to be consistent with the ground.

[0033] It should be noted that, in the present embodiment, the first pushing device 24 and the second pushing device 29 are driven by a cylinder; in addition, a fixed slider is provided on the mounting plate 21, a sliding rod is slidably provided on the fixed slider, the bottom of the sliding rod is connected to the output end of the first pushing device 24, the sliding rod is provided with a rack, and the mounting plate 21 is provided with an execution encoder whose input end is connected to a gear meshing with the rack, the execution encoder is electrically connected to the PLC control device, and when the value calculated by the execution encoder is consistent with the value fed back by the encoder to the PLC control device, the PLC control device controls the first pushing device 24 to stop operating, thereby ensuring that the distance between the cutter disc 23 and the ground is always consistent, avoiding inconsistent heights of the cutter disc 23 when cutting sugarcane, and preventing waste of resources.

[0034] For details, please refer to Figure 6The two groups of sugarcane lifting conveyor belts 30 are symmetrically arranged up and down, one of the two adjacent sugarcane lifting conveyor belts 30 is longer than the other sugarcane lifting conveyor belt 30, the two sugarcane lifting conveyor belts 30 symmetrically arranged up and down are connected to the synchronous chain 32 through the synchronous rotating shaft 31 for transmission, and the third driving motor 33 is arranged on the two upper sugarcane lifting conveyor belts 30. The two groups of sugarcane lifting conveyor belts 30 symmetrically arranged up and down enable the two adjacent sugarcane lifting conveyor belts 30 to effectively convey the sugarcane, thereby preventing each sugarcane from failing to flow between the two adjacent sugarcane lifting conveyor belts 30.

[0035] See also Figure 7 The leaf stripping conveying mechanism 40 is mainly used for stripping leaves from sugarcane. The leaf stripping conveying mechanism 40 includes an ascending conveying chain plate 41 and a horizontal stripping assembly 42 intersecting with the top of the ascending conveying chain plate 41. The ascending conveying chain plate 41 includes a conveying platform with a rotating shaft group. The chain plate is installed on the rotating shaft group of the conveying platform and is driven by a motor; the horizontal stripping assembly 42 includes a horizontal stripping frame 420. The feeding port and the discharging port of the horizontal stripping frame 420 are provided with a pushing roller group 421. An array of leaf stripping roller groups 422 are provided between the feeding port and the discharging port of the horizontal stripping frame 420. The leaf stripping roller group 422 is evenly distributed with leaf stripping claws 42 3. A second driving motor for driving the pushing roller group 421 and the leaf stripping roller group 422 is provided on the side of the horizontal stripping frame 420. Each sugarcane is transported to the pushing roller group 421 at the feed port through the ascending conveying chain plate 41. The sugarcane is pushed toward the discharge port by the pushing roller group 421. During the pushing process, the array leaf stripping roller group 422 strips the sugarcane. At the same time, the pushing roller group 421 at the discharge port pushes the sugarcane and sugarcane leaves out of the horizontal stripping frame 420. A fan is provided on the horizontal stripping frame 420 at the discharge port. The fan is used to blow the sugarcane leaves out of the horizontal stripping frame 420 to prevent the sugarcane leaves from flowing into the side-tilted silo 50.

[0036] Preferably, see Figure 8 In order to prevent the leaf stripping conveying mechanism 40 from stripping the sugarcane leaves uncleanly, a topping disc assembly 70 for cutting the top leaves of the sugarcane is arranged on the top of the cab 101. The topping disc assembly 70 includes a topping support frame 71 and a gathering turntable 72 for gathering the sugarcane leaves and a topping disc 73 for cutting the sugarcane leaves, which are respectively arranged on the topping support frame 71. The topping support frame 71 is provided with a second driving motor 74 for driving the gathering turntable 72 and the topping disc 73 to rotate. The sugarcane leaves are drawn to the topping disc 73 through the gathering turntable 72, so that the topping disc 73 strips the top of the sugarcane and the top sugarcane leaves, thereby effectively improving the efficiency of the leaf stripping conveying mechanism 40 in the subsequent sequence, and at the same time enabling the leaf stripping conveying mechanism 40 to strip the sugarcane leaves more cleanly.

[0037] More preferably, in order to enable the gathering turntable 72, the active sugarcane gathering disk 103 and the driven sugarcane gathering disk 104 to transport sugarcane more effectively, the circumferential edges of the gathering turntable 72, the active sugarcane gathering disk 103 and the driven sugarcane gathering disk 104 are evenly provided with shifting teeth 734, and the shifting teeth 734 are inclined inwardly toward the circumferential edge, and the shifting teeth 734 form an angle with the circumferential edge. By setting the shifting teeth 734 and the circumferential edge to form an angle, the sugarcane can be prevented from escaping from the gathering turntable 72, the active sugarcane gathering disk 103 and the driven sugarcane gathering disk 104 during their rotation, thereby improving the efficiency of transporting sugarcane.

[0038] The vertical whole-stalk sugarcane combine harvester described above is provided with a sugarcane harvesting mechanism 20, two sets of sugarcane lifting conveyor belts 30, a leaf stripping conveying mechanism 40, a front gathering assembly 60 and a topping blade assembly 70. The front gathering assembly 60 gathers the sugarcane to the sugarcane harvesting mechanism 20 for cutting, and then the two sets of sugarcane lifting conveyor belts 30 orderly convey the single upright sugarcane to the leaf stripping conveying mechanism 40 for sugarcane leaf stripping. The two sets of sugarcane lifting conveyor belts 30 are provided to avoid the accumulation and blockage of the leaf stripping conveying mechanism 40 when stripping leaves. During the conveying process of the two sets of sugarcane lifting conveyor belts 30, the topping blade assembly 70 also performs a top cutting on the sugarcane and cuts off the sugarcane leaves on the top of the sugarcane, thereby effectively improving the leaf stripping efficiency.
