Description

Technical Field

[0001] The present invention belongs to the field of machinery, specifically agricultural machinery technology, and specifically relates to an intelligent frame assembly for agricultural power transmission. This intelligent frame assembly connects a circuit system with a working module mounted on a frame platform, conveniently and efficiently enabling direct power supply, effectively reducing environmental pollution caused by the use of batteries or diesel engines in agricultural machinery. Background Art

[0002] Currently, the most widely used agricultural machinery in my country is ploughing machinery, mostly rotary tillers. Rotary tillers are primarily limited to tilling, requiring manual operation and being difficult to operate. Furthermore, they cannot perform other traditional tillage tasks such as sowing, cultivating the soil, and harvesting, or specialized tillage tasks for specific crops. Therefore, intelligent operating frames that can remotely complete the entire agricultural process and be used for a variety of crops are an effective means of reducing operating costs and increasing the automation and mechanization rates of agricultural machinery.

[0003] In recent years, researchers in related fields have also been conducting research on the automation of agricultural machinery and equipment. Among them, invention patent application 202311650426.7 discloses "an automated potato planting machine", which realizes the one-by-one collection and intermittent feeding of potato seed blocks, reducing the input of human resources. Utility model patent 202323238474.3 discloses "a wheat planter seeding device", which uses a feeding device, a rotating device, a protective device, a screening device and a discharging device to send qualified seeds out of the device one by one, thereby improving the degree of automation and practicality of the device. Invention patent application 202410726854.1 discloses "a vegetable planter with automatic ridge changing", which can realize automatic control, automatic ridge changing and forward and reverse sowing, making full use of planting space, high planting efficiency and low labor costs.

[0004] However, the above equipment still has the following problems: (1) It uses traditional fossil energy such as gasoline or batteries for energy supply. Fossil energy pollutes the environment greatly, while batteries are unstable and require frequent energy supply, resulting in reduced efficiency of agricultural machinery; (2) It has a single function and is difficult to disassemble and replace, which cannot meet the diverse needs of actual agricultural production; (3) When laying out wires over a large area, the cost of laying out the wires is high, and it is easy to cause line entanglement problems, which leads to increased production costs and difficulty in maintenance and replacement.

[0005] At present, the country is vigorously promoting the "dual carbon" strategy and the high-quality development plan of agricultural mechanization. Faced with many technical difficulties, we should widely seek and explore better technical solutions. Summary of the Invention

[0006] Based on the technical problems faced in the automation process of agricultural machinery in the prior art, this application provides an intelligent frame assembly for agricultural power transmission. The intelligent frame assembly is powered by a circuit system directly connected to a power source, and can complete multiple tasks by setting up working modules with different functions on the intelligent frame platform. This not only achieves continuous energy supply for agricultural machinery, but also conveniently and easily realizes direct power supply from the power source, effectively reducing the environmental pollution caused by the use of batteries or diesel engines in agricultural machinery and equipment, but also meets the demand for diversified functions in agricultural production and has broad application prospects.

[0007] The technical solution of the present invention:

[0008] An agricultural power transmission intelligent frame assembly comprises an intelligent frame and an auxiliary vehicle. The intelligent frame is connected to the auxiliary vehicle via a cable (1) and is further connected to a power source.

[0009] The intelligent frame includes a main frame (14) and a cable storage device, a positioning module and an operating device arranged on the main frame (14). Four support arms (6) are symmetrically arranged on both sides of the main frame (14), and the support arms (6) are fixedly connected to the main frame (14). The auxiliary vehicle consists of an auxiliary frame (18), a turntable (8) and a moving device arranged on the auxiliary frame (18); the turntable (8) obtains power through a turntable motor (9), and the cable (1) is connected to the turntable (8). The structure of the moving device is the same as that of the operating device of the intelligent frame. The intelligent frame is directly connected to the power supply through a bridge line, avoiding the traditional arable land agricultural machinery using the method of repeatedly adding fuel or replacing batteries to maintain the continuous operation of the agricultural machinery, which not only improves production capacity but also effectively reduces environmental pollution. The control system of the intelligent frame is connected to the cable storage device, the positioning module and the operating device respectively, and the control device of the auxiliary vehicle is connected to the turntable (8) and the moving device, thereby realizing remote control of the agricultural power transmission intelligent frame combination and improving production efficiency.

[0010] The cable storage device includes a cable storage tray (2) and a cable storage tray rotating motor (19), wherein the cable (1) is wound on the cable storage tray (2) and connected to the auxiliary vehicle via an on-board mechanical arm (17) provided on the main frame (14). The on-board mechanical arm (17) is connected to the mechanical arm rotating motor (11) provided on the main frame (14), thereby realizing the rotation of the mechanical arm; a circular cable interface (16) is provided at the end of the on-board mechanical arm (17), and the cable passes through the cable interface and is fixed to the on-board mechanical arm to prevent it from falling. The intelligent frame assembly described in the present application realizes reasonable collection and discharge of wires through the supporting auxiliary vehicle, effectively reduces wiring costs, and avoids the line entanglement problem caused by large-area wiring.

[0011] The positioning module is composed of a head RTK positioning module (4), a platform RTK positioning module (27) and a support arm RTK positioning module (3). The head RTK positioning module is arranged at the head of the main frame (14), the platform RTK positioning module (27) is arranged in the middle of the main frame (14), and the support arm RTK positioning module (3) is arranged on the support arm (6). Through the positioning module, the precise positioning of the intelligent frame is achieved, and the accuracy reaches the centimeter level.

[0012] The operating device is composed of four synchronously running vehicle legs, each of which is provided with a stepper motor (15) at the top, a rotating central shaft (30) with a tooth groove (31) at the periphery of the middle part, and a wheel (25) at the bottom. The power of the stepper motor (15) is transmitted to the chain transmission gear (7) via the chain transmission gear central shaft (27), and then connected to the driven gear (28) provided on the wheel (25) through the transmission chain (26). The driven gear (28) drives the wheel to move through the gear rotating central shaft (33). The rotating central shaft (30) is meshed with the transmission gear (34) through the tooth groove (31), and the transmission gear (34) obtains power by rotating the motor (10), thereby realizing the steering of the wheel. The rotating central shaft (30) and the transmission gear (34) are arranged in a matching space inside the support arm (6).

[0013] Preferably, each of the vehicle legs is further provided with a chain groove (13) for placing a transmission chain (26) so as to avoid interference with the movement of the rotating central shaft (30).

[0014] Preferably, each of the vehicle legs is provided with a latch hole (24) that matches the latch (32), and the height adjustment and fixation of the rotating central axis (30) on the vehicle leg are achieved through the cooperation of the latch (32) and the latch hole (24). Since the rotating central axis is arranged inside the support arm (6) fixedly connected to the main frame (14), the height adjustment of the main frame is achieved, thereby avoiding damage to crops during operation; thereby achieving the completion of diversified agricultural work at different heights and on different crop fields.

[0015] Preferably, a plurality of working component slots (5) are provided on the main frame (14) for installing different agricultural implements.

[0016] Preferably, bearings (23), anti-wear pads (22) and top covers (21) are symmetrically arranged at both ends of the rotating central shaft (30) from the inside to the outside, and are fixedly connected by bolts (20), thereby reducing rotational friction.

[0017] Power supply path:

[0018] The power supply is connected to the auxiliary vehicle through a cable and supplies power to it. The cable is coiled on a turntable and led out to be connected to the smart frame platform. Furthermore, the cable connected to the smart frame is adjusted by the 17 vehicle-mounted robotic arm, connected and coiled on the cable storage tray, thereby realizing long-term continuous power supply to the smart frame.

[0019] Location coordinates:

[0020] Assuming the operating plot is a plane, an x0y plane coordinate system is established. The agricultural power transmission intelligent vehicle frame assembly described in this application is placed on the ground. The intelligent frame platform plows and advances in the y direction, while the auxiliary vehicle moves in the x direction. When the auxiliary vehicle moves in the x direction, the intelligent frame platform moves synchronously in the x direction, that is, the x coordinates of the intelligent frame platform and the power-assisted vehicle remain consistent. Thus, through the coordination of the intelligent frame and the auxiliary vehicle, power supply is achieved while overcoming the problem of line entanglement, ensuring that the intelligent frame can reach any position on the operating plot.

[0021] Operation steps:

[0022] (1) The intelligent vehicle frame moves forward in the y direction: the power of the stepper motor (15) is transmitted to the chain transmission gear (7) via the chain transmission gear middle shaft (27), and then connected to the driven gear (28) provided on the wheel (25) through the transmission chain (26). The driven gear (28) drives the wheel to move forward through the gear rotation middle shaft (33). During the intelligent vehicle frame's forward movement, the auxiliary vehicle remains stationary; at the same time, the 2 on-board cable reel is rotated by the 40 on-board cable reel rotation motor to realize the cable 3 pay-out process. Through the adjustment of the 17 on-board mechanical arm, the cable is placed on the ground on the right side of the intelligent vehicle frame.

[0023] (2) The intelligent frame retracts along the y direction: When the intelligent frame reaches the end of one side of the cultivated land, the 15 stepper motor stops rotating; the 35 rotation motor starts, driving the 34 transmission gear to rotate and engage with the 31 tooth groove of the 30 rotation axis, thereby driving the rotation axis to rotate, thereby realizing the rotation of the vehicle legs. After the vehicle legs rotate 90 degrees, the 15 stepper motor starts again, causing the intelligent frame to move horizontally to the right to the next working position; at this time, the cable placed on the ground (the cable placed on the ground is stationary) is on the left side of the trolley, and the 17 vehicle-mounted robotic arm is adjusted to rotate 180 degrees to the side of the cable. Start the 15 stepper motor, driving the 25 wheel to rotate, realizing the retraction of the frame along the y direction; at the same time, the 2 vehicle-mounted cable reel realizes the cable winding process under the reverse rotation of the 40 vehicle-mounted cable reel rotation motor.

[0024] (3) The intelligent frame platform and the auxiliary vehicle simultaneously move to the next working position: the auxiliary vehicle starts and moves simultaneously with the intelligent frame in the X direction; after the translation is completed, the position of the vehicle-mounted robotic arm 17 is adjusted so that the cable is placed on the ground to the right of the intelligent frame. Repeat steps (1) and (2) to achieve reciprocating motion.

[0025] Beneficial effects of the present invention:

[0026] (1) The intelligent agricultural power transmission frame assembly provided in this application adopts a circuit system directly connected to a power source for power supply, which realizes convenient and easy direct power supply from the power source and effectively reduces the environmental pollution caused by the use of batteries or diesel engines in agricultural machinery and equipment.

[0027] (2) The intelligent frame combination for agricultural power transmission provided in this application completes the entire farming process by setting working modules with different functions on the intelligent frame platform, meets the diversity of user needs and realizes full-process mechanization, and has broad application prospects.

[0028] (3) The intelligent frame assembly for agricultural power transmission provided in this application, through cooperation with auxiliary vehicles, realizes the reasonable retraction and release of cables during the operation of the equipment, effectively reduces the wiring cost, and avoids the line entanglement problem caused by large-area wiring.

[0041] The present invention will be further described below with reference to the embodiments.

[0042] Example 1: Intelligent frame assembly for agricultural power transmission

[0043] The intelligent frame combination for agricultural power transmission includes an intelligent frame and an auxiliary vehicle. The intelligent frame is connected to the auxiliary vehicle via a cable 1, thereby connecting to the power supply. The intelligent frame includes a main frame 14 and a main control system, a cable storage device, a positioning module and an operating device arranged on the main frame 14; the main control system is respectively connected to the cable storage device, the positioning module and the operating device, thereby realizing remote control and improving production efficiency. Four support arms 6 are symmetrically arranged on both sides of the main frame 14, and the support arms 6 are fixedly connected to the main frame 14. The auxiliary vehicle consists of an auxiliary frame 18 and an auxiliary control device, a turntable 8 and a moving device arranged on the auxiliary frame 18. The auxiliary control device is respectively connected to the turntable 8 and the moving device; the turntable 8 obtains power through the turntable motor 9, and the cable 1 is connected to the turntable 8. The structure of the moving device is the same as that of the operating device of the intelligent frame.

[0044] The cable storage device includes a cable storage drum 2 and a cable storage drum rotating motor 19. The cable 1 is wound on the cable storage drum 2 and is connected to the auxiliary vehicle through an on-board mechanical arm 17 provided on the main frame 14. The on-board mechanical arm 17 is connected to the mechanical arm rotating motor 11 provided on the main frame 14, thereby realizing the rotation of the mechanical arm 17. A circular cable interface 16 is provided at the end of the on-board mechanical arm 17. The cable 1 passes through the cable interface 16 and is fixed to the on-board mechanical arm 17 to prevent it from falling. The intelligent frame assembly described in the present application realizes the reasonable storage and discharge of wires through the matching auxiliary vehicle, effectively reduces the wiring cost, and avoids the line entanglement problem caused by large-area wiring.

[0045] The positioning module consists of a head RTK positioning module 4, a platform RTK positioning module 27, and a support arm RTK positioning module 3. The head RTK positioning module 4 is located at the head of the main frame 14, the platform RTK positioning module 27 is located in the middle of the main frame 14, and the support arm RTK positioning module 3 is located on one of the support arms 6. These positioning modules enable precise positioning of the intelligent frame, achieving centimeter-level accuracy.

[0046] The operating device consists of four synchronously running legs. A stepper motor 15 is installed at the top of each leg, a rotating central shaft 30 with teeth 31 is installed on the outer periphery of the middle portion, and a wheel 25 is installed at the bottom. The power of the stepper motor 15 is transmitted to the chain transmission gear 7 via the chain transmission gear central shaft 27, and then connected to the driven gear 28 installed on the wheel 25 through the transmission chain 26. The driven gear 28 drives the wheel 25 to move through the gear rotating central shaft 33. The rotating central shaft 30 is engaged with the transmission gear 34 through the teeth 31. The transmission gear 34 obtains power from the rotating motor 10, thereby realizing the steering of the wheel 25. The two ends of the rotating central shaft 30 are symmetrically provided with bearings 23, anti-wear pads 22 and top covers 21 from the inside to the outside, and are fixedly connected with bolts 20 to reduce rotational friction. The rotating central shaft 30 and the transmission gear 34 are arranged in a matching space inside the support arm 6. In addition, each leg is provided with a latch opening 24 that matches the latch 32. Inserting the latch 32 into the latch opening 24 allows the height of the rotating axle 30 to be adjusted and fixed to the leg. Because the rotating axle 30 is disposed within the support arm 6, which is fixedly connected to the main frame 14, the height of the main frame 14 can be adjusted.

[0047] Example 2: Intelligent frame assembly for agricultural power transmission

[0048] Different from the first embodiment, each of the vehicle legs is further provided with a chain groove 13 for placing a transmission chain 26 , thereby preventing the transmission chain 26 from interfering with the rotation of the rotating central shaft 30 .

[0050] Different from the first embodiment, the main frame 14 is provided with a plurality of working component slots 5 for mounting different agricultural implements, such as rotary tillage implements, weeding implements, spraying implements, harvesting implements or storage implements.

[0051] Example 4: Operation steps of the intelligent frame assembly for agricultural power transmission

[0052] (1) Power supply path:

[0053] The smart vehicle-frame assembly utilizes a two-stage power supply, with the auxiliary vehicle dividing the power supply into two phases: the first phase, from the power source to the auxiliary vehicle, and the second phase, from the auxiliary vehicle to the smart vehicle-frame. The power source connects to the auxiliary vehicle via a cable 1, which is coiled around a turntable 8 and then connected to the smart vehicle-frame. The cable 1, connected to the smart vehicle-frame, is adjusted by an onboard robotic arm 17 before being connected and coiled around a cable storage tray 2, ensuring long-term, continuous power supply to the smart vehicle-frame.

[0054] (2) Operation principle:

[0055] Assuming the operating plot is a plane, establish an x0y plane coordinate system; wherein, the intelligent frame platform plows and advances in the y direction, and the auxiliary vehicle moves in the x direction; and when the auxiliary vehicle moves in the x direction, the intelligent frame platform moves synchronously in the x direction, that is, the x coordinates of the intelligent frame platform and the power-assisted vehicle are always consistent. It can be seen from this that, combined with the two-stage power supply principle and travel mode of the present application, the power-assisted vehicle always moves in the X direction and retracts and releases the cable, while the intelligent frame is responsible for moving in the Y direction and retracting and releasing the cable as needed. Therefore, through the cooperation of the intelligent frame and the auxiliary vehicle, power supply is achieved under the premise of overcoming the problem of line entanglement, thereby ensuring that the intelligent frame can reach any position in the operating plot.

[0056] (3) Operation steps:

[0057] 1. The intelligent vehicle frame advances in the y-direction: The power of the stepper motor 15 is transmitted to the chain drive gear 7 via the chain drive gear shaft 12, and then connected to the driven gear 28 on the wheel 25 via the transmission chain 26. The driven gear 28 drives the wheel 25 via the gear rotation shaft 33. During the intelligent vehicle frame's advancement, the auxiliary vehicle remains stationary; simultaneously, the cable storage tray 2 is rotated by the cable storage tray rotation motor 19 to release the cable 3. The onboard robotic arm 17 rotates and adjusts the cable 3 to the ground on the right side of the intelligent vehicle frame.

[0058] 2. The intelligent frame retracts along the y-direction: When the intelligent frame reaches the end of one side of the cultivated land, the stepper motor 15 stops rotating; the rotating motor 10 starts, driving the transmission gear 34 to rotate and engage with the tooth groove 31 of the rotating central shaft 30, thereby driving the rotating central shaft 30 to rotate, thereby realizing the rotation of the vehicle legs. After the vehicle legs rotate 90 degrees, the stepper motor 15 starts again, causing the intelligent frame to move horizontally to the right to the next working position. At this time, the cable placed on the ground (the cable placed on the ground is stationary) is on the left side of the trolley, and the on-board mechanical arm 17 is adjusted to rotate 180 degrees to the side of the cable. The stepper motor 15 is started, driving the wheel 25 to rotate, realizing the retraction of the frame along the y-direction; at the same time, the cable storage tray 2 realizes the cable 3 winding process under the reverse rotation of the cable storage tray rotating motor 19.

[0059] 3. The smart frame and the auxiliary vehicle simultaneously move to the next operating position: The auxiliary vehicle starts and moves simultaneously with the smart frame in the X direction. After the translation is completed, the position of the onboard robotic arm 17 is adjusted so that the cable 3 is placed on the ground to the right of the smart frame. Repeat steps (1) and (2) to achieve reciprocating motion.
