[0002] Currently, mechanized sugarcane harvesting both domestically and internationally mainly employs combined cutting harvesters and step-by-step cutting and impurity removal equipment. Both methods involve cutting the sugarcane into multiple small sections and then using blowers to remove sugarcane leaves and other debris. This results in many small fragments being blown away. Furthermore, combined cutting harvesters are heavy and prone to crushing sugarcane rootstocks, while step-by-step cutting and impurity removal makes it difficult to return the sugarcane leaves to the field. In summary, current harvesting methods suffer from high loss rates, high breakage rates, high impurity rates, and difficulties in returning sugarcane leaves to the field. Sugarcane farmers and sugar mills find these harvesting methods unacceptable. Therefore, a more suitable sugarcane harvesting machine is urgently needed to solve the problems existing in current technologies. Utility Model Content

[0034] In one embodiment, a roller motor 9 drives the sorting roller 24 to rotate. Along the rotation direction of the sorting roller 24, multiple rows of sugarcane hooks are evenly spaced, forming an angle of approximately 60 degrees with the roller. Sugarcane is laid horizontally on each row of sugarcane hooks. The sorting roller 24 is used to straighten the sugarcane and roll it onto the rotary conveyor 23 as needed. The rotary conveyor 23 is equipped with conveyor rollers, which are assembled from three serrated polyurethane pieces fixed circumferentially to a roller plate. A hydraulic cylinder pushes the conveyor rollers to move along the rotary conveyor 23. The conveyor rollers push the sugarcane onto the sugarcane tail baffle and align it. The conveyor rollers also straighten the sugarcane and deliver it to the tail-cutting blade holder 22. The tail-cutting blade holder 22 has two shears, one on each side. Each shear has a rotating shaft at one end and a hydraulic cylinder at the other end. The extension and retraction of the hydraulic cylinders cuts off the aligned sugarcane tails.

[0035] In this embodiment, a sorting baffle 31 is provided on the right side of the sorting roller 24. When the conveying roller pushes the sugarcane to the sugarcane tail baffle, the hydraulic cylinder of the sorting baffle 31 is pushed out at the same time, pushing the sorting baffle 31 to contact the sorting roller 24 and lifting out the sugarcane that is about to fall.

[0036] In one embodiment, the leaf-stripping box 19 is fixed on the chassis 10, and the leaf-stripping box 19 is provided with leaf-stripping rollers 20 and sugarcane feeding rollers. After the sugarcane on the rotating conveyor frame 23 is pushed into the leaf-stripping box 19 by the conveying rollers, the sugarcane feeding rollers continue to convey the sugarcane forward. Multiple leaf-stripping rollers 20 are spaced apart on the top of the sugarcane feeding rollers. The leaf-stripping rollers 20 are used to strip the leaves from the sugarcane.

[0037] In one embodiment, a sugarcane leaf separation device 21 is provided at the outlet end of the leaf stripping box 19, and the sugarcane leaf separation device 21 extends to the outside of the chassis 10.

[0038] like Figure 3 The oil supply system 17 shown includes a hydraulic oil tank 13, oil pump A27, oil pump B30, and oil pump 28. The aforementioned three oil pumps are respectively connected to the three output ends of the gearbox 18. The input end of the gearbox 18 is connected to the power output end of the traction drive device. Oil pump 28 is connected to the pilot handle operating system 3, solenoid valve 12, and solenoid valve 14 through an oil circuit. Oil pump A27 is connected to the actuators of the large hook arm 5, large hook claw 8, rotary conveyor frame 23, tail shear holder 22, large sorting roller 24, push plate 25, and sorting baffle 31 through an oil circuit and hydraulic multi-way valve 15. Oil pump B30 is connected to the actuators of the leaf stripping roller 20 and sugarcane feeding roller through an oil circuit and hydraulic multi-way valve 15.

[0039] The scissor closing mechanism and the start / stop end of the conveyor rollers of the tail cutter holder 22 are programmed with logic based on the stroke duration. The intelligent control system 2 performs the relevant functional actions according to the logic program instructions. The large sorting roller 24 and the push plate 25 are programmed with logic based on the rotation angle and stroke duration. The intelligent control system 2 performs the relevant functional actions according to the program instructions. Both the intelligent control system 2 and the logic program can be implemented using existing mature programming equipment or software, and are not the inventive point of this utility model; therefore, they will not be elaborated further here.

[0040] The sugarcane leaf sorting device is installed at the outlet of the leaf-stripping box 19 and consists of rubber strips to block sugarcane leaves and four high-pressure jet nozzles. The rubber strips are evenly suspended on the baffle at the outlet of the leaf-stripping box 19, preventing sugarcane leaves and other debris from coming out with the sugarcane. The four high-pressure jet nozzles blow the sugarcane leaves and other debris outside the leaf-stripping box 19. The jet nozzles are controlled by solenoid valve 12, which is controlled by the control system. When the conveyor rollers on the rotating conveyor frame 23 feed the sugarcane into the leaf-stripping box 19, the control system sends a command to solenoid valve 12, which immediately operates, initiating the blowing and shut-off actions to save air supply.

[0041] In this embodiment, the traction drive device is a tractor 1, which is detachably connected to the cleaning vehicle. The rear output shaft of the tractor 1 drives the large gear 26 of the gearbox 18 to rotate, the large gear 26 drives the small gear 29 to rotate, the large gear 26 also drives the small oil pump to rotate, and the small gear 29 drives the oil pump A27 and the oil pump B30 to rotate.

[0042] The operating steps of this cleaning equipment are as follows: The operator operates the pilot handle operating system 3 to control the hook arm hydraulic rotation system 4, large hook arm 5, small hook arm 7, and large hook claw 8 to grab the sugarcane (crushed and piled by a cutter, spreader, or manually) and place it into the push plate 25. Then, the operator operates the intelligent control system 2 to control the automatic control cabinet 6. The automatic control cabinet 6 instructs the sorting roller 24 to work. Under the rotation of the sorting roller 24, the sugarcane piled on the push plate 25 is sorted and tumbled onto the rotating conveyor frame 23. The conveyor rollers on the rotating conveyor frame 23 straighten the sugarcane according to the logic instructions and send it to the tail shearing blade holder 22. When the sugarcane tail hits the sugarcane tail baffle, the left and right shears on the tail shearing blade holder 22 cut off the sugarcane tail according to the logic instructions. At the same time, the sorting baffle 31 contacts the sorting roller 24 to support the sugarcane that is about to fall. Next, the rotating conveyor 23 rotates to the inlet of the peeling box 19 according to instructions, and the conveying rollers then transport the sugarcane into the peeling box 19 according to instructions. Subsequently, the peeling rollers 20 and the sugarcane feeding rollers inside the peeling box 19 clean the sugarcane leaves and other debris according to instructions and transport them to the outside. Finally, the sugarcane leaf separation device 21 operates to separate the sugarcane leaves and other debris to the outside of the peeling box 19.

[0043] The sugarcane impurity removal equipment provided by this utility model has the following advantages:

[0044] 1. When this sugarcane cleaning equipment is working, it separates and processes the sugarcane tail (cut at 22 points on the tail shearing blade) and the withered sugarcane (separated at 19 points on the leaf stripping box) in separate steps. In this way, the fresh sugarcane tail can be used to feed animals such as cattle and sheep, while the withered sugarcane leaves and other debris are returned to the field on the spot, which can increase soil fertility.

[0045] 2. The sugarcane after leaf removal by this sugarcane cleaning equipment is a whole stalk, similar to the effect of manual harvesting. There is no loss of sugarcane juice or fragments, which greatly reduces the loss rate problem of mechanized sugarcane harvesting.

[0046] 3. It is lightweight, and the wheel track of the cleaning vehicle can be set according to the sugarcane row spacing requirements. It does not crush the sugarcane, protects the sugarcane ratoon, and has no impact on the sugarcane germination rate in the following year.

[0047] 4. This equipment first cuts off the sugarcane top and then peels off the withered old leaves. The peeled sugarcane is relatively clean with a relatively low impurity rate (approximately within 1-3%), which is a sugarcane harvesting method that sugar mills and sugarcane farmers are happy to accept.

[0048] 5. This cleaning equipment consumes about 0.7 liters of oil per ton of sugarcane during operation, while the cutting combine harvester consumes more than 4 liters of oil per ton of sugarcane. Obviously, this cleaning equipment greatly saves energy and reduces environmental pollution during operation.
