Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an electric drive agricultural machinery. Background Technology

[0002] Agricultural machinery is generally divided into two parts: the working part and the traveling part. The working part, such as plow blades and mower blades, requires power to drive. The traveling part supports and moves the entire machine and usually houses control components. These control components provide power output and control for the working part. Current agricultural machinery typically uses mechanical transmissions, such as screws, to drive the working parts, such as rotary tillage or mowing. This design has several problems. First, the working part uses a screw drive, a rigid connection, making it highly susceptible to the influence and control of the traveling part, limiting operational flexibility. For example, lifting is difficult to control unless a lifting device is added to the driving motor in the traveling part. However, this modification is not only costly but also requires sufficient space in the traveling part to accommodate the lifting requirements of the driving motor.

[0003] Furthermore, once the screw is damaged, not only the traveling part but also the working part needs to be repaired simultaneously. This not only increases maintenance costs but also prolongs maintenance time and reduces overall work efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See Figures 1 to 5 This utility model provides an electrically driven agricultural machine, characterized in that it includes:

[0028] A frame 1, on which a power supply battery 101 is mounted;

[0029] Walking device 2, which is mounted on the frame 1, and is electrically connected to the power supply battery 101 via a cable;

[0030] The working device 3 is provided with a working mechanism 301 and a lifting mechanism 5. The working mechanism 301 includes a working part 302 and a drive motor 303. The working part 302 is connected to the drive motor 303 through a transmission. The drive motor 303 is electrically connected to the power supply battery 101 through a cable. The working part 302 is fixedly connected to the lifting mechanism 5. The lifting mechanism 5 is rotatably mounted on the frame 1.

[0031] Control device 4 is mounted on the frame 1. The control device 4 includes a control element 401, which is communicatively connected to the walking device 2 and the drive motor 303.

[0032] This utility model provides an electric drive agricultural machinery, including: a frame 1, a walking device 2, a working device 3, and a control device 4. The walking device 2 includes a walking motor and walking wheels. The walking motor is connected to the walking wheels to drive the electric drive agricultural machinery to walk. The walking motor is electrically connected to the control element 401 to control the rotation speed, thereby precisely adjusting the travel speed. The working mechanism 301 is connected to the frame 1 through the lifting mechanism 5. The drive motor 303 is used to drive the working part 302 to operate, realizing operations such as tilling, harvesting, or sowing. The control element 401 adjusts the output power of the drive motor 303 according to the operation requirements to ensure stable operation efficiency. The power supply battery 101 provides power to the entire system through cables. By independently powering the working part 302 with the drive motor 303 set separately on the working device 3, the energy loss and structural complexity caused by traditional mechanical transmission are avoided, improving transmission efficiency and ease of maintenance. By arranging the power supply battery 101 on the frame 1, the weight of the working device 3 can be effectively reduced, thereby improving the stability and operability of the whole machine. At the same time, it is convenient for centralized management and protection of the battery. Furthermore, the power supply battery 101 is connected to the drive motor 303 through a cable, so the continuity and safety of power supply will not be affected when the lifting mechanism 5 is in operation, ensuring stable and reliable power transmission during operation.

[0033] In a further embodiment of this invention, the control device 4 further includes a walking controller 402 and a work controller 403. Both the walking controller 402 and the work controller 403 are communicatively connected to the control element 401. The walking controller 402 is communicatively connected to the walking device 2, and the work controller 403 is communicatively connected to the drive motor 303.

[0034] In this embodiment, the walking controller 402 is used to receive operation commands issued by the control element 401 and adjust the speed and direction of the walking motor to realize forward, backward and turning control. The operation controller 403 adjusts the start / stop, speed and output torque of the drive motor 303 according to the commands of the control element 401 to adapt to the needs of different working conditions and realize refined operation control. By separating the walking control and operation control, the response speed and control accuracy of the system are improved, while facilitating functional expansion and ensuring efficient and stable operation of the machinery in complex farmland environments.

[0035] In a further embodiment of this invention, a lifting drive device 102 is also provided on the frame 1. The lifting drive device 102 is connected to the lifting mechanism 5 in a transmission manner. The lifting drive device 102 is used to drive the lifting mechanism 5 to rotate relative to the frame 1. The lifting drive device 102 is communicatively connected to the control element 401.

[0036] In this embodiment, the lifting drive device 102 receives instructions through the control element 401 and drives the lifting mechanism 5 to complete the lifting and lowering action of the working device 3, so as to realize the rapid separation of the working part 302 from the ground or precise entry into the soil. When transporting or turning, the working device 3 can be quickly raised to reduce the frictional resistance with the ground, avoid wear of the working parts, and reduce power consumption. When entering the working area, the control element 401 precisely controls the lifting drive device 102 to lower the working mechanism 301 according to preset parameters or real-time terrain feedback, so as to ensure that the working part 302 cuts into the soil at the best angle and depth, thereby improving the consistency of operation and the quality of cultivation.

[0037] In a further embodiment of this invention, the lifting drive device 102 is a hydraulic rod, one end of which is rotatably mounted on the frame 1, and the other end of which is rotatably connected to the lifting mechanism 5.

[0038] In this embodiment, the hydraulic rod is powered by the hydraulic system, which has the advantages of rapid response, stable output and strong overload protection, and can reliably execute lifting commands in complex terrain; its two ends adopt a hinged structure to adapt to the relative movement between the frame 1 and the lifting mechanism 5, ensuring smooth transmission without jamming.

The fixed frame 503 is fixedly connected to the working part 302, and the adjusting arm 502 is a telescopic adjusting arm.

[0040] In this embodiment, the relative position between the articulated frame 501 and the fixed frame 503 can be changed by adjusting the telescopic movement of the adjustable arm 502, thereby adjusting the pitch angle and soil penetration depth of the working part 302 in the working state. The operator can preset the optimal working posture according to different working parts 302 and soil conditions, improving versatility and adaptability. Specifically, the telescopic adjustable arm is a turnbuckle structure. By rotating the turnbuckle to adjust its effective length, the distance between the articulated frame 501 and the fixed frame 503 can be precisely controlled, thereby fine-tuning the tilt angle of the working device 3. This structure has a self-locking function, which can remain stable under alternating loads, prevent loosening caused by vibration during operation, and ensure the consistency and reliability of tillage depth.

[0041] In a further embodiment of this invention, the hinge frame 501 is provided with a first spherical connector 504, the fixed frame 503 is provided with a second spherical connector 505, and both ends of the adjusting arm 502 are provided with connecting holes 506, which are rotatably connected to the first spherical connector 504 and the second spherical connector 505 respectively.

[0042] In this embodiment, the cooperation between the first spherical connector 504 and the connecting hole 506 allows the adjusting arm 502 to rotate flexibly in multiple degrees of freedom, ensuring smooth relative movement between the hinge frame 501 and the fixed frame 503, avoiding motion interference caused by installation errors or deformation, and further ensuring the accuracy and stability of the posture adjustment of the working device 3.

[0043] In a further embodiment of this invention, a first hinge seat 507 is provided on the upper part of the hinge frame 501. The first hinge seat 507 is hinged to one end of the hydraulic rod, so that the hinge frame 501 and the hydraulic rod are rotatably connected.

[0044] In this embodiment, the first hinge seat 507 has a first through hole, and the telescopic end of the hydraulic rod has a second through hole. The two are hinged together by a pin, which ensures that the hydraulic rod maintains a stable rotational relationship with the hinge frame 501 during the telescopic process. This connection structure has the characteristics of convenient assembly and simple disassembly and maintenance.

[0045] In a further embodiment of this invention, a second hinge seat 508 is provided at the lower part of the hinge frame 501, and a third hinge seat 103 is provided on the frame 1. The second hinge seat 508 and the third hinge seat 103 are hinged together so that the hinge frame 501 and the frame 1 are rotatably connected.

[0046] In this embodiment, the second hinge seat 508 is provided with a third through hole, and the third hinge seat 103 is provided with a fourth through hole. The two are hinged by a connecting pin through the joint, which ensures that the hinge frame 501 rotates smoothly around the frame 1 under the drive of the hydraulic rod, and realizes the reliable transmission of the lifting action of the working part 302. This connection structure has the characteristics of convenient assembly and simple disassembly and maintenance.

[0047] In a further embodiment of this invention, the working part 302 includes a housing 304 and a cutter shaft 305. The housing 304 is connected to the lifting mechanism 5, and the cutter shaft 305 is connected to the drive motor 303. A protective cover 306 is provided on the housing 304, and the drive motor 303 is disposed inside the protective cover 306.

[0048] In this embodiment, the housing 304 covers the outside of the cutter shaft 305, effectively preventing soil and rocks from splashing during operation and ensuring operational safety; the protective cover 306 can provide protection, preventing the drive motor 303 from being subjected to external impacts or dust intrusion during operation, improving the stability and service life of the motor; at the same time, the protective cover 306 is provided with heat dissipation holes to achieve efficient heat dissipation, ensuring that the temperature rise is within a safe range during long-term operation.
