Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery and equipment technology, specifically relating to a backpack-type sugarcane harvesting device. Background Technology

[0002] Sugarcane is an important economic crop in my country and the main raw material for sugar production. Currently, sugarcane harvesting in China mainly relies on manual labor, especially in Yunnan Province, where the terrain is mostly hilly and mountainous, making it difficult for large combine harvesters to access the fields. The complex terrain also does not meet the operational requirements for large combine harvesters. Harvesting is entirely manual, resulting in high labor intensity and low harvesting efficiency. The manual sugarcane harvesting process involves manually cutting the sugarcane at the base with a hand-held machete, followed by manually piling and bundling the sugarcane.

[0003] Existing research on backpack-type sugarcane harvesters mainly focuses on the design of backpack-type electric sugarcane harvesters, with the main research content being the design of the cutter head structure.

[0004] The backpack electric sugarcane harvester patent proposed by Cai Weijun et al. (CN202222846342.8) mainly fixes the cutting disc, ensures safety through the design of the first and second motors, and improves the stability of battery fixation by designing pads and sliding grooves.

[0005] The patent for a backpack-type electric sugarcane harvester proposed by Fang Jianyu et al. (CN202121111378.0) optimizes the backpack frame structure, reduces the risk of burns, and improves the safety of the cutting process through the design of the protective cover for the cutting disc.

[0006] The patent for a backpack electric sugarcane harvester proposed by Wenming Fu et al. (CN202020504926.5) mainly focuses on the design of the blade harvesting mechanism. It harvests sugarcane by rapidly rotating the cutting blade and cuts the sugarcane roots by rotating the arc blade, thereby reducing the workload of the planting personnel.

[0007] Backpack-type electric sugarcane harvesters are generally powered by batteries. Sugarcane roots are thick and well-developed, and the power provided by batteries is limited, resulting in short battery life and frequent charging and discharging, leading to low operating efficiency and unsuitability for prolonged harvesting operations. Current technology lacks specific design and development for harvesters based on the manual harvesting process, sugarcane field terrain, and the physical characteristics of sugarcane. It lacks an orderly plowing function, failing to ensure effective stacking and baling of cut sugarcane roots. The complex and harsh environment of sugarcane fields, with its undulating terrain, makes real-time adjustment of the sugarcane root cutting angle impossible. Furthermore, the stability of the sugarcane stalks cannot be guaranteed during cutting, resulting in low cutting efficiency. The harvester design does not consider ergonomics, failing to guarantee working comfort and leading to high labor intensity. Summary of the Invention

[0008] In view of this, this utility model refers to the manual harvesting process, takes into account both root cutting and orderly felling functions, is easy to hold, and allows for adjustment of operating posture, which can effectively reduce labor intensity.

[0022] Based on the above scheme, the first shoulder strap is an anti-gravity shoulder strap.

[0023] Based on the above solution, the grip assembly includes a connecting rod and a grip;

[0024] The connecting rod is fixed to the rigid transmission component by a clamp, and the handle is triangular and fixed to the connecting rod.

[0025] Based on the above scheme, the transmission assembly includes rigid transmission components and flexible transmission components;

[0028] Based on the above scheme, the powertrain includes an engine, a reducer, a second belt, and a back pad;

Detailed Implementation

[0046] To make the objectives, advantages and features of this utility model more apparent, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] like Figure 1 As shown, a backpack-type sugarcane harvester mainly includes a cutter head assembly 1, a back frame assembly 2, a handle assembly 3, a transmission assembly 4, and a power assembly 5. During operation, the engine provides power, which is transmitted to the blades through the transmission assembly. The operator holds the handle with their left hand and uses the rigid transmission assembly with their right hand to cut the sugarcane at the root. After the root is cut, the left hand presses down on the handle to push the sugarcane to one side.

[0048] like Figure 2 As shown, the cutter head assembly 1 includes a limit frame 101, a cutting blade 102, a support frame 103, a protective cover 104, and a baffle plate 105. The limiting frame 101 is V-shaped and is mounted on the rigid transmission component 401 via clamps. After the cutting blade 102 contacts the sugarcane, the interaction between the moving cutting blade 102 and the stationary sugarcane causes the cutter head assembly 1 to shift to one side. The sugarcane is blocked by the limiting frame 101 and cannot move, allowing the rotating cutting blade 102 to cut the sugarcane. This ensures the stability of the cutter head assembly 1 during sugarcane cutting, reduces shaking, and ensures cutting efficiency. The cutting blade 102 is a serrated circular blade, which can efficiently cut the sugarcane stalks by rotating. One end of the support frame 103 is U-shaped and welded to the limiting frame 101, while the other end is a smooth arc shape that contacts the sugarcane field. This allows the cutter head assembly 1 to be smoothly pushed across the sugarcane field and provides support and adjusts the cutting angle during cutting. The protective cover 104 is mounted on the rigid transmission component via clamps to prevent stones and debris from flying and injuring people during cutting, thus improving work safety. The deflector plate 105 is welded to the clamp, and the front end is arc-shaped. Before root cutting, the front end of the deflector plate 105 contacts the sugarcane and guides the sugarcane into the left side of the deflector plate 105. At this time, the sugarcane is subjected to the lateral force of the deflector plate 105, which can make the sugarcane tilt to one side after root cutting.

[0049] like Figure 3 As shown, the back frame assembly 2 includes a back strap 201, a back frame 202, a hanging ring 203, a rope 204, and a hanging ring 205. The back strap 201 is an anti-gravity strap, which can evenly distribute pressure across the entire strap, improving comfort. The back frame 202 is designed for front-facing carrying. The hanging ring 203 is bolted to the back frame 202, and the hanging ring 205 is bolted to a clamp on the rigid transmission component 301. One end of the rope 204 is attached to the hanging ring 203, and the other end is attached to the hanging ring 205. By adjusting the position of the hanging ring 205 on the rigid transmission component 401 and the length of the rope 204, the suspension height of the rigid transmission component 401 can be adjusted to accommodate different body heights. The hanging ring 205 is fixed at an appropriate position on the rigid transmission component 401 for easy suspension of the rigid transmission component 401.

[0050] like Figure 4 As shown, the handle assembly 3 includes a connecting rod 301 and a handle 302. The connecting rod 301 is fixed to the rigid transmission component 401 by a clamp, and the handle 302 is triangular and welded to the connecting rod 301. It provides good grip comfort. When working, the left hand holds the handle 302. After the sugarcane root is cut, the left hand presses down, which can drive the lever 105 to tilt the sugarcane to one side.

[0051] like Figure 5As shown, the transmission assembly 4 includes a rigid transmission component 401 and a flexible transmission component 402. The outer tubes of the rigid transmission component 401 and the flexible transmission component 402 are connected, and each contains an independently rotatable transmission flexible shaft. The flexible transmission component 402 is connected to the output end of the power assembly 5, and the output end of the rigid transmission component 401 is connected to the cutter head assembly 1. The power of the engine 501 drives the cutting blade 102 to rotate through the flexible transmission component 402 and the internal transmission flexible shaft of the rigid transmission component 401. The flexible transmission component 402 can be bent freely, which improves the flexibility of operation. The operator holds the rigid transmission component 401 with one hand to move the cutter head assembly 1, which is convenient for aligning with the cutting target.

[0052] like Figure 6 As shown, the powertrain 5 includes an engine 501, a reducer 502, a shoulder strap 503, and a back frame 504. The engine 501 provides the power to drive the cutting blade 102, offering stronger power and longer operating time compared to a battery. The reducer 502, installed at the output end of the engine 501, reduces the cutting blade's rotational speed, increases cutting torque, enhances cutting force, and effectively reduces engine vibration, improving working comfort. The shoulder strap 503 features padded shoulders to evenly distribute pressure and enhance comfort. The back pad 504 is fixedly connected to the engine 501, allowing for easy carrying of the engine 501 from behind, enabling it to move with the sugarcane during harvesting.

[0053] The working process of the backpack-type sugarcane harvester is as follows:

[0054] The manual person carries the back pad 504 from behind and the back frame 202 from the front. By adjusting the position of the hanging ring 205 on the rigid transmission component 401 and the length of the rope 204, a balance point can be found, which can achieve the suspension of the cutter head assembly 1 and the rigid transmission component 401. The suspension height is adjustable. The right hand holds the rigid transmission component 401 to a comfortable position, and the left hand holds the handle 302. During harvesting, start the engine, adjust the height of the rigid transmission component 401 with your right hand so that the support frame 103 contacts the sugarcane field for support, and the cutting plate 105 contacts the sugarcane stalk, subjecting the sugarcane to lateral force. At the same time, adjust the cutting angle of the sugarcane stalk, and the cutting blade 102 contacts the sugarcane. Under the action of the limiting frame 101, the sugarcane remains stable and is cut quickly. At this time, press the handle 302 with your left hand, and the sugarcane tilts to one side under the action of the cutting plate 105, making it easier to pile and bundle later. Then adjust the height of the rigid transmission component 401 held by your right hand, and with the support of your body, the cutter head assembly 1 and the rigid transmission component 401 are suspended in the air. Walk to the next sugarcane to be cut (this method can reduce the labor intensity of moving the cutter head assembly 1 and the rigid transmission component 401 and improve comfort), and then continue the above harvesting process.
