Description

Technical Field

[0001] This invention relates to the field of crop harvesting technology, and in particular to a harvesting method for harvesting floating rice on the bank using a combine harvester. Background Technology

[0002] In many parts of my country, coal resources and arable land resources overlap significantly, inevitably leading to land subsidence and damage caused by coal mining activities. For example, in the Huaihe River mining area, subsidence zones have accumulated to over 1.1 million mu (approximately 73,333 hectares). Therefore, coordinating the relationship between coal mining and arable land protection is crucial. Protecting traditional land resources while exploring non-traditional arable land resources to expand grain planting areas and overcoming the natural limitations of scarce traditional arable land is key to solving the problem.

[0003] Floating rice refers to a new planting model that uses floating beds, floating islands, floating boards, and other technologies to grow rice on the water surface, allowing it to suspend and grow. This planting model can effectively solve the problems of reduced arable land and food security in coal mining subsidence and waterlogging areas. However, there is currently no supporting mechanized equipment for harvesting floating rice.

[0004] The main challenge in harvesting floating rice is that mechanical equipment is difficult to operate on water, and manual harvesting is inefficient and costly. Therefore, designing a method for harvesting floating rice is both necessary and urgent for achieving large-scale floating rice planting and harvesting. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a harvesting method for floating rice on the shore based on a combine harvester, which can improve work efficiency, save a lot of labor costs, and ensure the possibility of large-scale promotion of floating rice.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a harvesting device is provided, including a combine harvester, a conveying platform, an adjustable support, a winch device, a combine harvester working platform, and a separating device; the combine harvester is placed on the combine harvester working platform, the conveying platform is placed on the adjustable support, and a winch device is provided at one end of the conveying platform and a separating device is provided at the other end.

[0007] The winch device is used to winch the floating rice planting floats after they have been harvested by the combine harvester.

[0008] The conveying platform is used to convey the floating rice planting floats that are being lifted by the winch device, and the separating device separates the planting cups from the floating rice planting floats.

[0009] In a preferred embodiment of the present invention, the conveying platform includes a main conveyor belt located on both sides, an auxiliary conveyor belt located between the main conveyor belts, a control console, and a power mechanism; the surface of the auxiliary conveyor belt is provided with protrusions to increase friction with the floating rice planting float; the power mechanism is the power system of the conveying platform and the winch device, and the control console is used to adjust the rotation speed and direction of the conveyor belt.

[0010] Furthermore, a claw hook is provided on the pulley at one end of the main conveyor belt to assist in grabbing the floating rice planting pontoons after they have been harvested by the combine harvester.

[0011] Furthermore, the winch device includes a steel cable and a hook, which are mounted on a rotating shaft at one end of the two main conveyor belts and are used to lift the floating rice planting float after it has been harvested by the combine harvester.

[0012] In a preferred embodiment of the present invention, the adjustable bracket is installed below the conveying platform to adjust the slope and height of the conveying platform.

[0013] In a preferred embodiment of the present invention, the outriggers of the combine harvester working platform are adjustable outriggers, used to adjust the height of the combine harvester.

[0014] In a preferred embodiment of the present invention, the height of one end of the conveying platform equipped with the winch device is lower than the height of the combine harvester's working platform.

[0015] In a preferred embodiment of the present invention, the separation device includes an outer frame, a crank, a connecting rod, a toothed sector, a set of pressure rods arranged at equal intervals and connected to each other, and corresponding pressure rod sleeves. The lower end of the pressure rod is provided with a pressure plate. The crank, connecting rod, and toothed sector are rotatably connected in sequence. The toothed sector is in contact with a pressure rod, transmitting power to the pressure rod so that it moves up and down in the corresponding pressure rod sleeve. When the pressure rod moves downward, the pressure plate applies pressure to the planting cup so that it detaches from the floating rice planting float.

[0016] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is: to provide a harvesting method for harvesting floating rice on the bank using a combine harvester based on any of the above-mentioned harvesting devices, comprising the following steps:

[0017] Step 1: Select mature floating rice;

[0018] Step 2: Assemble the mature floating rice units together.

[0019] Step 3: Transport the assembled planting units from Step 2 to the shore and harvest them using a harvesting device;

[0020] Step 4: After the floating rice in Step 3 is harvested, a separation device is used to separate the planting cup from the planting float.

[0021] Step 5: Recycle the soil substrate and planting floats.

[0022] In a preferred embodiment of the present invention, in step two, the specific method for constructing and splicing mature floating rice units is as follows: several planting floating boards are aligned along their long sides and spliced ​​together to form a harvesting unit with half the length. Several harvesting units are then spliced ​​together by four corner frames to form a floating rice harvesting chain.

[0023] The beneficial effects of this invention are: This invention utilizes a front-end combine harvester to harvest floating rice, and controls the harvesting speed of the floating rice through a conveyor platform, enabling mechanized harvesting by the combine harvester, greatly improving harvesting efficiency while saving manpower. This invention has a simple and reasonable structure, improving the work efficiency of large-scale floating rice harvesting. Attached Figure Description

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0031] Please see Figure 1 The embodiments of the present invention include:

[0032] A harvesting method for floating rice on the bank using a combine harvester includes the following steps:

[0033] Step 1: Select mature floating rice;

[0034] Step 2: Assemble the mature floating rice units together.

[0035] In this example, the smallest planting unit for floating rice is a planting float 1m long and 0.5m wide. The rice harvesting unit is constructed and assembled as follows: Figure 2 As shown, 12 planting floating boards, each 1m long and 0.5m wide, are aligned along their long sides and spliced ​​together, with nuts securing the joints to form a small harvesting unit 6m long and 1m wide. This small harvesting unit facilitates the subsequent retrieval of the planting floating boards. These small harvesting units are then spliced ​​together to form a floating rice harvesting chain. In this example, the small harvesting units are spliced ​​together using a four-corner frame. Preferably, to prevent the floating rice planting floating boards from falling off during transport, the four legs of the four-corner frame 7 are tilted inwards at a 5° angle. Considering the maximum tensile force of the harvesting device and the load-bearing capacity between the floating boards, the number of small units spliced ​​together in a single operation is no more than four.

[0036] Step 3: Transport the assembled planting units from Step 2 to the shore and harvest them using a harvesting device;

[0037] Step 4: After the floating rice in Step 3 is harvested, a separation device is used to separate the planting cup from the planting float.

[0038] Step 5: Recycle the soil substrate and planting floats.

[0039] See Figure 3 The harvesting device includes a combine harvester 5, a conveying platform 1, an adjustable support 2, a winch 3, a combine harvester working platform 4, and a separating device 6. The combine harvester 5 is placed on the combine harvester working platform 4, and the conveying platform 1 is placed on the adjustable support 2. The winch 3 is installed at one end of the conveying platform 1, and the separating device 6 is installed at the other end. The winch 3 is used to winch the floating rice planting floats after they have been harvested by the combine harvester 5; the conveying platform 1 is used to convey the floating rice planting floats won by the winch 3, and the separating device 6 separates the planting cups on the floating rice planting floats.

[0040] The conveyor platform 1 includes chain guards 16 on both sides, a main conveyor belt 11, an auxiliary conveyor belt 12 located between the main conveyor belts 11, a power mechanism 15, and a control console 14. A claw hook 13 is respectively installed on two pulleys 17 at one end of the main conveyor belt 11 to assist in grabbing the floating rice planting pontoons after they have been harvested by the combine harvester 5. The surface of the auxiliary conveyor belt 12 has rubber protrusions to increase friction with the floating rice planting pontoons. The power mechanism 15 is the power system for the conveyor platform 1 and the winch device 3, and can be an electric motor, etc. The control console 14 is used to adjust the speed and direction of the conveyor belts, thereby controlling the rice harvesting speed.

[0041] The structural diagram of the hoisting device 3 is as follows: Figure 4 As shown, it includes a steel cable 31 and a hook 32, which are set on a rotating shaft between two pulleys 17 equipped with claw hooks 13, and are used to lift the floating rice planting float after it has been harvested by the combine harvester 5.

[0042] The adjustable bracket 2 is installed below the conveyor platform 1 to adjust the slope and height of the conveyor platform 1. Specifically, the adjustable bracket 2 is connected to the chain guard plate 14 to support the conveyor platform 1. The legs of the adjustable bracket 2 are adjustable up and down, and the first I-beam 21 is fixed between the four legs to reinforce the stability of the adjustable bracket 2. In practical applications, the height of one end of the conveyor platform 1 equipped with the winch device 3 is slightly lower than the height of the combine harvester 5's working platform, facilitating the landing of the harvested floating rice planting floats on the conveyor platform 1 for transport.

[0043] The combine harvester working platform 4 includes a steel plate 43 and support legs 41 located at the four ends of the steel plate 43. The support legs 41 are adjustable and used to adjust the height of the combine harvester 5. Specifically, the adjustable bracket 2 and the adjustable support legs can be automatically adjusted, such as hydraulic support legs, or manually adjusted. To increase the stability of the combine harvester working platform 4, a second I-beam frame 42 is installed between the four support legs 41. When the combine harvester working platform 4 is fixed on the bank, the support legs are adjusted so that the steel plate 41 is about 5cm above the water surface, ensuring that the planting float can pass smoothly under the combine harvester working platform 4 to complete the rice harvest while leaving relatively short rice roots.

[0044] Combination Figure 5The separation device 6 includes an outer frame 64, a crank 61, a connecting rod 62, a gear sector 63, a set of interconnected, equally spaced pressure rods 65, and corresponding pressure rod sleeves 66. There are four pressure rods 65, equally spaced within the plane of the outer frame 64, connected by a connecting rod 69 to allow synchronous movement. A pressure plate 68 is provided at the lower end of each pressure rod 65 to increase the contact area with the planting cup. There are four pressure rod sleeves 66, with each of the four pressure rods 65 passing through its corresponding sleeve. The four pressure rod sleeves 66 are connected and fixed to the left and right sides of the outer frame 64 by a fixing rod 67, allowing the pressure rods 65 to slide up and down within the pressure rod sleeves 66. Crank 61, connecting rod 62, and toothed sector 63 are connected in sequence for rotation. The handle of toothed sector 63 is fixed to one side of outer frame 64 by pulley structure. The toothed sector is connected to a pressure rod 65 through tooth meshing, which transmits power to the pressure rod 65 so that it moves up and down in the corresponding pressure rod sleeve 66. When the pressure rod 65 moves downward, pressure plate 68 applies pressure to the planting cup so that it is detached from the floating rice planting float.

[0045] The working process of the rice harvesting device is described below:

[0046] 1. Placement of the harvesting equipment;

[0047] Choose a relatively flat location on the bank and place the combine harvester's working platform 4 close to the shore. Adjust the outriggers 41 so that the platform's steel plate 43 is about 5cm above the water surface. After the combine harvester's working platform 4 is securely placed, mount the combine harvester 5 onto the platform. The harvesting head of the combine harvester 5 should be parallel to the working platform and extend 10cm beyond it to ensure smooth harvesting when the rice reaches the harvesting head. After the front harvesting section is in place, dig a slope with a gradient of 20-30° directly behind the combine harvester's working platform 4. Place the floating conveyor section within the dug slope and adjust the adjustable bracket 2 so that the height of the front end of the conveyor platform 1 is slightly lower than the height of the combine harvester's working platform 4.

[0048] 2. Rice harvesting;

[0049] After the harvesting device is installed, the assembled harvesting unit is dragged to the front of the combine harvester working platform 4. The power mechanism 15 is started, and the conveyor belt is reversed through the control console 14 to release the steel cable 31 of the winch device 3. The steel cable 31 is guided to pass under the combine harvester working platform 4 and reach the harvesting unit. The hooks 32 are then hung on both sides of the harvesting unit. The combine harvester 5 is started, and the conveyor belt is controlled to rotate forward to drag the harvesting unit towards the conveyor platform 1. When the harvesting unit reaches the front of the conveyor platform 1, the hooks are released, and the harvesting unit is hung on the claw hooks 13 of the two main conveyor belts 11. The harvesting unit moves backward with the conveyor belt to complete the rice harvesting.

[0050] 3. The planting cup is separated from the planting float;

[0051] After harvesting, the planting cups, along with the planting floats, move towards the separation device 6 via the conveyor platform 1. When they reach the bottom of the separation device 6, the control console presses down the pressure rod 65, and the pressure plate 68 contacts the planting cups, thus separating the planting cups from the planting floats under pressure.

[0052] 4. Recycle the separated soil substrate and planting floats.

[0053] This invention utilizes a front-end combine harvester to harvest floating rice. The harvesting speed is controlled by a conveyor platform, enabling mechanized harvesting by the combine harvester, significantly improving harvesting efficiency while saving manpower. The invention has a simple and reasonable structure, improving the efficiency of large-scale floating rice harvesting.
