Description

Technical Field

[0001] This utility model relates to the field of amphibious harvester technology, specifically to an amphibious combine harvester and an amphibious combine harvester system. Background Technology

[0002] Aquatic plants (such as reeds, rushes, and weeds) grow in rivers, lakes, and other bodies of water. Due to eutrophication and other factors, these aquatic plants reproduce rapidly. Excessive proliferation of aquatic plants can cover the water surface, block sunlight, cause underwater plants to die, and disrupt the aquatic ecosystem. Furthermore, their excessive growth consumes oxygen in the water, affecting the growth of fish and other aquatic organisms. Additionally, aquatic plants can clog waterways, hindering river transport operations. The decaying plant matter can also breed disease-carrying organisms such as mosquitoes, impacting environmental hygiene. However, aquatic plants are rich in fiber, which can be recycled, for example, as raw materials for papermaking.

[0003] Traditionally, the clearing and harvesting of aquatic plants is done manually, which is very inefficient.

[0004] In recent years, some technologies have also employed vessels or harvesting equipment capable of operating on water for harvesting. These vessels or harvesting equipment are equipped with shears to cut the plants, and a large amount of grass falls into the water during the cutting process. Then, a dredging vessel is used to retrieve the fallen pieces from the water for further processing. In some technical solutions, the vessels used for cutting and harvesting aquatic plants are also equipped with devices for retrieving the fallen pieces and processing them.

[0005] However, the above methods of harvesting aquatic plants still have drawbacks. During the process of cutting aquatic plants with scissors, a large amount of material will still fall into the water. This will either require subsequent water surface cleaning or cause the material to rot on the water surface, affecting the hygiene of the water area and subsequent production. Utility Model Content

[0006] The main purpose of this utility model is to provide an amphibious combine harvester, which aims to solve the problem that a large amount of material falls into the water during existing aquatic plant harvesting methods, resulting in the need for subsequent water surface dredging and cleaning work or affecting water sanitation and subsequent production.

[0007] To achieve the above objectives, the amphibious combine harvester proposed in this utility model includes an amphibious walking device and a foamed hull, as well as a rotating cutting component disposed at one end of the foamed hull; the rotating cutting component includes a harvesting trough and a transport channel for mutual communication; the harvesting trough is open at both ends, and a plurality of rotating harvesting components are partially housed in one of the openings of the harvesting trough, the rotating harvesting components extending beyond the harvesting trough, each of the rotating harvesting components including two sets of harvesting blades for opposite rotation, a feeding gap being formed between the two sets of harvesting blades, so as to use the opposite rotation of the two sets of harvesting blades to feed the material into the feeding gap in the cutting trough for material cutting, and input the material cut in the feeding gap into the transport channel through the other opening of the harvesting trough.

[0008] Optionally, one end of the transport channel away from the harvesting trough is connected to a crushing channel; a wheel-type shredder is provided in the crushing channel to crush the cut material.

[0009] Optionally, the end of the crushing channel opposite to the transport channel is connected to the material conveying channel, and the end of the material conveying channel opposite to the crushing channel forms a discharge port.

[0010] Optionally, the amphibious combine harvester further includes a connecting arm and a drive device. The first end of the connecting arm is hinged to the foamed hull, the second end of the connecting arm is used to connect the rotating cutting component, and the drive device is used to drive the first end of the connecting arm to rotate, thereby raising and lowering the rotating cutting component connected to the second end of the connecting arm.

[0011] Optionally, the transport channel and the crushing channel are connected by a flexible channel so that when the rotary cutting component is lifted, the transport channel and the crushing channel can remain connected by the deformation of the flexible channel.

[0012] Optionally, the harvesting trough is further provided with two lateral guide structures at one end for harvesting the material, and a gradually narrowing guide space is formed between the two lateral guide structures to guide the material to gather from both sides of the lateral direction toward the rotating harvesting assembly.

[0013] Optionally, the upper wall of the harvesting trough is also connected to a baffle structure to form a barrier between the material and the personnel operating space of the foamed hull when the material is conveyed to the rotating harvesting assembly.

[0014] Optionally, the foamed hull includes a sealed outer shell, the interior of which is filled with a foam layer, and the feeding gap extends vertically.

[0015] Optionally, the amphibious walking device is a tracked vehicle.

[0016] To achieve the above objectives, this utility model also proposes an amphibious combined harvesting system, including the amphibious combined harvester and a tugboat; the tugboat is used to collect the material crushed and output by the amphibious combined harvester.

[0017] In this invention, the amphibious walking device and foamed hull enable the harvester to be used both on land and in water. When the harvester is used for plant harvesting in water, it is driven to approach the harvesting area, causing the rotating harvesting components in the rotating cutting unit to contact the material to be harvested. The two sets of harvesting blades in each rotating harvesting component rotate in opposite directions, causing the material to enter the harvesting trough under the force of rotation. The material is then conveyed and cut in the feeding gap, and transported to the transport channel by the transmission force generated by the opposite rotation of the two sets of harvesting blades. Therefore, in this invention, the material to be harvested first enters the opening of the harvesting trough through the transmission force provided by the oppositely rotating harvesting blades, and then is conveyed in the feeding gap and cut by the two oppositely rotating harvesting blades. This avoids the problem of plants being directly cut in the water, which would require subsequent surface dredging and cleaning, or affect water hygiene and subsequent production.

[0026] This utility model proposes an amphibious combine harvester.

[0027] Please refer to Figures 1 to 3To achieve the above objectives, the amphibious combine harvester proposed in this utility model includes an amphibious walking device 1 and a foamed hull 2, as well as a rotating cutting component 3 disposed at one end of the foamed hull 2. The rotating cutting component 3 includes a harvesting trough 31 and a transport channel 32 for mutual communication. The harvesting trough 31 is open at both ends, and a plurality of rotating harvesting components 33 are partially housed in one of the openings of the harvesting trough 31. The rotating harvesting components 33 extend beyond the harvesting trough 31. Each rotating harvesting component 33 includes two sets of harvesting blades 331 for rotating in opposite directions. A feeding gap 332 is formed between the two sets of harvesting blades 331, so that the material is fed into the feeding gap 332 in the cutting trough by the two sets of harvesting blades 331 rotating in opposite directions for material cutting. The material cut in the feeding gap 332 is then input into the transport channel 32 through the other opening of the harvesting trough 31.

[0028] In this invention, the amphibious walking device 1 and the foamed hull 2 ​​enable the harvester to be used both on land and in water. When the harvester is used for plant harvesting in water, it is driven to approach the harvesting area, causing the rotating harvesting components 33 in the rotating cutting parts 3 to contact the material to be harvested. The two sets of harvesting blades 331 in each rotating harvesting component 33 rotate in opposite directions, causing the material to enter the harvesting trough 31 under the force of rotation. The material is then conveyed and cut in the feeding gap 332, and transported to the transport channel 32 by the transmission force generated by the opposite rotation of the two sets of harvesting blades 331. Therefore, in this invention, the material to be harvested first enters the opening of the harvesting trough 31 through the transmission force provided by the oppositely rotating harvesting blades 331, and then is conveyed in the feeding gap 332 and cut by the two oppositely rotating harvesting blades 331. This avoids the need for subsequent surface dredging and cleaning work, or problems affecting water hygiene and subsequent production, caused by plants being directly cut in the water.

[0029] Specifically, the number of rotary harvesting components 33 in this invention is not limited; it can be any number of one or more sets, such as two, three, or four sets. In this embodiment, two sets of rotary harvesting components 33 are provided, thereby providing two feeding gaps 332.

[0030] The harvesting trough 31 contains a plurality of rotating harvesting components 33 within one of its openings. The rotating harvesting components 33 can extend partially beyond the harvesting trough 31, which facilitates the harvesting blades 331 contacting the aquatic plants or straw to be harvested and rolling and conveying the material into the harvesting trough 31.

[0031] For each rotary harvesting assembly 33, two cutter shafts can be arranged side by side, and each cutter shaft is provided with a set of harvesting cutter heads 331. Preferably, the harvesting cutter heads 331 form multiple rows of harvesting blades along the direction of the cutter shaft (for example, each cutter shaft forms five rows of harvesting blades). By driving the two cutter shafts of the same rotary harvesting assembly 33 to rotate in opposite directions, the blades on the harvesting cutter heads 331 move in opposite directions, guiding the material to be transported and cut into the harvesting trough 31.

[0032] Specifically, the harvesting head 331 may include several toothed disc blades arranged vertically, with a ring of teeth surrounding the outer edge of the discs, so as to improve the material transmission force of the rotating harvesting assembly 33 through the prying action of the teeth during rotation.

[0033] The amphibious combine harvester of this invention, through its amphibious walking device 1 and lightweight foamed hull 2, enables the harvesting of aquatic plants (such as reeds, rushes, and weeds) in water. Similarly, the harvester of this invention can also be used on land to harvest terrestrial plants such as straw, and the principle is the same as that for harvesting aquatic plants, which will not be elaborated here. When harvesting terrestrial plants, the cut material is also drawn into the harvesting trough 31, which can avoid the subsequent cleanup work caused by a large amount of cut material falling to the ground.

[0034] Optionally, one end of the transport channel 32 away from the harvesting trough 31 is used to communicate with the crushing channel 34; a wheel-type shredder 341 is provided in the crushing channel 34 to crush the cut material.

[0035] Specifically, at least one set of wheel-type shredders 341 is installed in the crushing channel 34. After the material is cut by the harvesting head 331, it is pushed from the harvesting trough 31 to the transport channel 32 by the transmission force provided by the rotating harvesting assembly 33, and then enters the crushing channel 34. The wheel-type shredders 341 in the crushing channel 34 shred the material and provide a driving force for conveying it to the rear end. Specifically, the wheel-type shredders 341 can be arranged in various ways. For example, their rotating shafts can be arranged vertically or horizontally. When the rotating shaft of the shredder is arranged vertically, the crushing channel 34 can also be formed between two sets of wheel-type shredders 341. When the rotating shaft of the shredder is arranged horizontally, the material can be crushed by the compression of the inner wall of the shredder and the crushing channel 34, and the shredded material can be conveyed to the rear end by the rotational force.

[0036] Specifically, the wheel-type shredder 341 can also be a double-roll crusher.

[0037] Furthermore, the end of the crushing channel 34 opposite to the transport channel 32 is connected to the conveying channel 35, and the end of the conveying channel 35 opposite to the crushing channel 34 forms a discharge port 38. Even further, the discharge port 38 is used to output the crushed material to a hopper. The hopper can be a fixed or movable type installed on the foamed hull 2, or it can be a tugboat.

[0038] Specifically, the material conveying channel 35 can be a material conveying pipe.

[0039] In one specific embodiment, the crushing channel 34 extends upward at an angle toward the conveying channel 35. The conveying channel 35 includes a first channel, a second channel, and a third channel connected in sequence. The first channel connects to the end of the crushing channel 34, and the third channel forms the discharge port 38. The second channel is arranged laterally. The first channel extends upward from the crushing channel 34 to connect with the second channel, and the third channel extends downward at an angle from the second channel to form the discharge port 38.

[0040] The harvesting trough 31, transport channel 32, crushing channel 34 and conveying channel 35 connected in sequence in this utility model form a channel for material harvesting, cutting, shredding and conveying. The power for material cutting, crushing and conveying is provided by the rotating harvesting assembly 33 and the wheel-type shredding device 341. Furthermore, a conveying scheme of scraper and conveyor belt can also be set in the channel.

[0041] Optionally, the amphibious combine harvester further includes a connecting arm 4 and a drive device. The first end of the connecting arm 4 is hinged to the foamed hull 2, and the second end of the connecting arm 4 is used to connect to the rotating cutting component 3. The drive device is used to drive the first end of the connecting arm 4 to rotate, thereby raising and lowering the rotating cutting component 3 connected to the second end of the connecting arm 4. The second end of the connecting arm 4 may specifically be connected to the end of the transport channel 32.

[0042] Furthermore, the harvester is equipped with a control room, which serves as the control center for the entire system. It is used to control the harvester's movement and steering, operate the lifting and lowering of the rotating cutting component 3, drive the harvesting head 331 for harvesting, and drive the wheel-type shredder 341 for material crushing.

[0043] In one specific embodiment, the transport channel 32 and the crushing channel 34 are connected by a flexible channel so that when the rotating cutting component 3 is lifted, the transport channel 32 and the crushing channel 34 can remain connected by the deformation of the flexible channel.

[0044] The flexible channel can be implemented using a deformable soft material. When the rotating cutting component 3 is lifted, the flexible channel is elongated to maintain communication between the transport channel 32 and the crushing channel 34 as the distance increases. Conversely, when the rotating cutting component 3 is lowered, the flexible channel is shortened to maintain communication between the transport channel 32 and the crushing channel 34 as the distance decreases. There are various ways to implement the flexible channel; for example, it can be a corrugated pipe.

[0045] Optionally, the harvesting trough 31 is further provided with two lateral guide structures 36 at one end for harvesting the material, and a gradually narrowing guide space is formed between the two lateral guide structures 36 to guide the material to gather from both sides of the lateral direction toward the rotating harvesting assembly 33.

[0046] Specifically, the two lateral guide structures 36 have the function of guiding terrestrial or aquatic plants towards the harvesting trough 31. The lateral guide structure 36 can be a guide plate, guide rod, or other structure with a guiding function. Furthermore, a guiding angle is formed between the two lateral guide structures 36.

[0047] Furthermore, a baffle structure 37 is connected to the upper wall of the harvesting trough 31 to form a barrier between the material and the personnel operating space of the foamed hull 2 ​​when the material is conveyed to the rotating harvesting assembly 33. The baffle structure 37 is used to prevent the material from falling into the personnel operating space (e.g., the driver's cab) on the foamed hull 2 ​​when it enters the harvesting trough 31, so as to avoid obstructing the operator's field of vision and improve the accuracy and safety of operation.

[0048] Optionally, the foamed hull 2 ​​includes a sealed outer shell, the interior of which is filled with a foam layer, and the feeding gap 332 extends vertically.

[0049] The foamed hull 2 ​​reduces the overall weight of the harvester, while the sealed outer shell prevents water from seeping into the hull and increasing its weight during underwater operations. Specifically, the sealed outer shell can be a metal shell.

[0050] Optionally, the amphibious walking device 1 is a walking track, i.e., an amphibious walking track, which is existing technology and will not be described in detail here.

[0051] The amphibious track can be made of aluminum alloy shell and polymer materials. The harvester can be powered by an internal combustion engine or an electric motor.

[0052] To achieve the above objectives, this utility model also proposes an amphibious combined harvesting system, including the amphibious combined harvester and a tugboat; the tugboat is used to collect the material crushed and output by the amphibious combined harvester.

[0053] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
