Description

Technical Field

[0001] The invention belongs to the technical field of reed prevention and control, and in particular relates to a reed harvester suitable for swamps. Background Art

[0002] Swamp reeds are an important part of wetland ecosystems, but their excessive growth can also bring a series of negative effects, such as obstructing water flow, reducing biodiversity, and affecting human activities. The hazards of excessive growth of swamp reeds are specifically reflected in the following three aspects: First, the hydrological cycle is blocked. The dense growth of reeds will hinder water flow, cause water retention, and cause water quality deterioration; the water storage capacity of the swamp is reduced, drainage is not smooth, and even floods and waterlogging disasters are caused. Secondly, biodiversity declines. Excessive reeds will occupy the living space of other aquatic plants, leading to the monotony of wetland plant communities, affecting the habitat and reproduction of other aquatic organisms, reducing biodiversity, and destroying the stability of wetland ecosystems. Finally, it affects human activities. Excessive growth of reeds will affect human activities such as shipping, fisheries, and tourism; dense reeds hinder ship navigation, affect fishery production, and affect wetland landscapes, reduce tourism value, and cause economic losses. Therefore, it has become an important task to rationally manage swamp reeds and balance ecology and utilization.

[0003] At present, the measures to control and remove reeds mainly include physical, chemical and biological technologies. Chemical control technology mainly uses herbicides to inhibit the growth of reeds, but this method has serious ecological risks. In terms of the ecological environment, herbicides will pollute water bodies, affect the survival of aquatic organisms, and even cause damage to the food chain. Because herbicides are sprayed in the environment where organisms live, they accumulate in the organisms and eventually enter the human body through the food chain, causing harm to human health. At the same time, long-term use of herbicides will cause reeds to develop drug resistance, affecting the weed control effect. Biological control technology uses natural enemies of reeds, such as insects and fungi, to control the growth of reeds. Studies have found that the use of biological agents to control reeds can achieve good results in a relatively short period of time, but it is only a temporary solution and not a permanent solution. After a period of time, the reeds will regenerate, and the impact of biological control on the ecosystem is highly uncertain, which still needs in-depth exploration and research.

[0004] Physical control technology mainly uses harvesters for treatment, but traditional harvesters have many problems. For example, the crawler reed harvesting technology developed in the UK is equipped with a pulley transport mechanism between the harvesting device and the folding transport bin for transporting reed stems, and a baling device is set between the harvesting device and the telescopic bin for post-harvest sorting, realizing integrated harvesting and baling operations, but it must be operated by multiple people during operation and is not suitable for operation in water. The reed harvester produced in Hungary uses a 4-wheel or 6-wheel self-propelled chassis, a reciprocating cutter, and no reed clamping and conveying device. The harvester works better when the ground of the reed field is flat and solid, but its performance will be affected if it is in a muddy, deep muddy swamp, tidal flat and other reed fields. The typical model of the harvester developed in China is the self-propelled straw baler of Shandong Yutian Agricultural Machinery Co., Ltd., which can be used for harvesting, crushing, picking and baling reeds, but it uses a wheeled walking chassis and is not suitable for tidal flat operations. Summary of the invention

[0045] Swamp reed is an important component of wetland ecosystems, but its overgrowth can also bring a series of negative effects, such as obstructing water flow (impeding the hydrological cycle), reducing biodiversity, and affecting human activities. Therefore, it has become an important task to rationally manage swamp reed and balance ecology and utilization.

[0046] At present, the measures to control and remove reeds mainly include physical, chemical and biological technologies. Chemical control technology mainly uses herbicides to inhibit the growth of reeds, but this method has serious ecological risks. In terms of the ecological environment, herbicides will pollute water bodies, affect the survival of aquatic organisms, and even cause damage to the food chain. Because herbicides are sprayed in the environment where organisms live, they accumulate in the organisms and eventually enter the human body through the food chain, causing harm to human health. At the same time, long-term use of herbicides will cause reeds to develop drug resistance, affecting the weed control effect. Biological control technology uses natural enemies of reeds, such as insects and fungi, to control the growth of reeds. Studies have found that the use of biological agents to control reeds can achieve good results in a relatively short period of time, but it is only a temporary solution and not a permanent solution. After a period of time, the reeds will regenerate, and the impact of biological control on the ecosystem is highly uncertain, which still needs in-depth exploration and research.

[0047] Physical control technology mainly uses harvesters for treatment, but traditional harvesters have many problems. For example, the crawler reed harvesting technology developed in the UK is equipped with a pulley transport mechanism between the harvesting device and the folding transport bin for transporting reed stems, and a baling device is set between the harvesting device and the telescopic bin for post-harvest sorting, realizing integrated harvesting and baling operations, but it must be operated by multiple people during operation and is not suitable for operation in water. The reed harvester produced in Hungary uses a 4-wheel or 6-wheel self-propelled chassis, a reciprocating cutter, and no reed clamping and conveying device. The harvester works better when the ground of the reed field is flat and solid, but its performance will be affected if it is in a muddy, deep muddy swamp, tidal flat and other reed fields. The typical model of the harvester developed in China is the self-propelled straw baler of Shandong Yutian Agricultural Machinery Co., Ltd., which can be used for harvesting, crushing, picking and baling reeds, but it uses a wheeled walking chassis and is not suitable for tidal flat operations.

[0048] Since the above-mentioned prevention and control technologies have the problems of poor control effect, secondary pollution to the environment, and even ecological damage, the research on efficient and environmentally friendly control technology has received close attention.

[0093] A placement area is formed between the second connecting shaft mounting seat 142 and the blade chuck 12, and the portion of the connecting shaft 14 located in the placement area is located in the hollow area, that is, the second connecting shaft mounting seat 142 is located above the finger chain 4, and the blade chuck 12 and the disc blade 13 are located below the finger chain 4. The connecting shaft 14 does not contact the finger chain 4 during operation, that is, the operation of the finger chain 4 does not interfere with the operation of the connecting shaft 14. This arrangement is used to harvest the reeds when the reeds are transported to the working area of ​​the disc blade 13 of the harvesting mechanism 2;

[0094] The motor 2 400 drives the connecting shaft 14 to rotate through a bevel gear set (i.e., a bevel gear set formed by the meshing connection between the active bevel gear 2 16 and the driven bevel gear 2 401), thereby driving the disc blade 13 to rotate and cut. When the blade contacts the root of the reed located in the circular hole 500, the reed cutting is completed.

[0095] In the present invention, the traveling mechanism 3 is composed of a traveling assembly 30, a bearing shell 301, and two frames 18; the clamping and transporting mechanism 1 and the harvesting mechanism 2 are installed inside the frame 18, and the three major mechanisms are assembled to form a complete assembly.

[0096] The frame 18 is fixedly mounted on the vehicle bottom plate 24, wherein a dividing plate 19 is mounted at the front end of the frame 18. The dividing plate 19 gathers the reeds into the channel during the forward movement of the reed harvester, thereby preventing the reeds from being rolled under the vehicle. A collection box 29 is placed at the rear of the frame, and the cut reed stalks are transported to the collection box 29; the front wheel assembly 31 of the harvester realizes steering control. When the harvester needs to turn during operation, the steering motor 23 drives the gear rack assembly 22 to operate, thereby driving the front wheel 20 on the steering linkage assembly 21 to rotate;

[0097] Specifically, when the harvester moves forward, the motor 11 drives the active bevel gear 111 to operate, which drives the driven bevel gear 112 to operate, and then drives the sprocket shaft 7 to rotate, thereby driving the sprocket 5 to rotate, causing the finger chain 4 to rotate, and the two adjacent finger chains 4 rotate relative to each other to form a clamping channel. The reed-dividing plate 19 at the front end of the frame gathers the reeds in front of the vehicle into the channel of the clamping and transporting mechanism 1, so that the reeds are fixedly clamped and transported backward. When the bottom of the reed contacts the disc blade 13 of the harvesting mechanism 2, the motor 2 400 drives the disc blade 13 to rotate to complete the cutting of the reed, and the reed stems continue to be transported backward to the collection box 29. At this time, the harvesting of the reeds is completed.

[0098] The rear wheel assembly 32 of the harvester provides power drive, and the drive motor 27 drives the axle 25 to operate through the cylindrical gear set 26, thereby driving the rear wheel 50 to rotate;

[0099] An air cushion 28 is welded and fixed on the vehicle bottom plate 24, and the air cushion 28 can provide a certain buoyancy for the vehicle body to prevent the vehicle body from sinking due to its own weight. At the same time, the outer circumferential surfaces of the front wheels 20 and the rear wheels 50 are evenly distributed with walking blades 40, that is, the design adopts the appearance of a circular paddle, which can also reduce a certain amount of resistance when moving forward in the swamp.
