Abstract
Description
Technical Field
[0001] This utility model relates to an agricultural machinery support structure, and more particularly to a high-legged, steerable agricultural machinery support structure, belonging to the field of agricultural machinery technology. Background Technology
[0002] Agricultural machinery, also known as agricultural equipment, generally refers to various machines used in the production process of crop cultivation, such as soil tillage machinery, planting and fertilization machinery, pesticide application machinery, and agricultural product harvesting machinery. Agricultural machinery can replace human labor in completing some heavy agricultural production tasks, helping to improve operational efficiency; it can provide suitable growing environments for crops, increasing yield and quality; at the same time, the popularization and application of agricultural mechanization has promoted the modernization of agriculture, shifting agricultural production from relying mainly on human and animal power to relying mainly on mechanical power, significantly improving grain production efficiency.
[0003] During operation, agricultural machinery often requires movable support structures to adjust its height. For example, pesticide spraying machinery needs different spraying heights at different crop growth stages (such as seedling and flowering stages), and harvesting machinery needs different heights for different crop varieties. However, existing movable support structures for agricultural machinery are relatively simple and cannot be independently adjusted for steering and height. Therefore, a single movable support structure can only support machinery operating on specific crops at specific times, resulting in low practicality. Furthermore, existing movable support structures cannot precisely control the steering angle, requiring manual adjustments during movement. This is particularly inconvenient for large agricultural machinery or when operating on smaller farmlands, making manual steering and adjustment difficult and inefficient. Utility Model Content
[0004] In view of the shortcomings of existing technology, this utility model provides a high-legged steerable agricultural machinery support structure that can autonomously adjust the steering during operation and accurately control the steering angle.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0006] A high-legged, steerable agricultural machinery support structure includes an agricultural machinery body. A high-legged steering mechanism is mounted on the agricultural machinery body. The high-legged steering mechanism includes two support frames symmetrically fixedly installed at the bottom of the agricultural machinery body. Two motors are symmetrically fixedly installed on the top of the support frames. A gearbox connected to the motors is fixedly installed on the bottom of the support frames. A steering column is installed at the bottom of the gearbox. A hydraulic lifting frame is installed at one end of the steering column. A drive wheel is fixedly installed at the bottom of the hydraulic lifting frame. An angle sensor is installed on one side of the hydraulic lifting frame.
[0007] Furthermore, a torque limiter connected to the transmission shaft on the gearbox is fixedly installed on the output end of the motor.
[0008] Furthermore, a connecting sleeve is fixedly installed on the steering column, and multiple bolts are evenly installed on the connecting sleeve. Multiple threaded holes that mate with the bolts are opened on the connecting end of the hydraulic lifting frame.
[0009] Furthermore, the hydraulic lifting frame is provided with multiple sliding grooves, a protective frame is slidably installed between two of the sliding grooves, and a protective cover is fixedly installed on the surface of the hydraulic lifting frame.
[0010] Furthermore, the top of the protective frame and the bottom of the protective cover are both inlaid with mutually attractive magnetic blocks.
[0011] Furthermore, a mounting base is fixedly installed on the hydraulic lifting frame, and multiple springs are symmetrically fixedly installed inside the mounting base. A locking rod is fixedly installed at one end of each spring, and locking blocks are fixedly installed on both sides of the angle sensor.
[0012] Furthermore, the diameter of the locking rod matches the inner diameter of the slot on the locking block; preferably, one end of the locking rod is arc-shaped.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This application utilizes a high-foot support steering mechanism, enabling the agricultural machinery to autonomously adjust its steering during operation and precisely control the steering angle. During use, a motor drives gears in the gearbox, which in turn rotate the steering column and hydraulic lifting frame via multiple gear sets, causing the hydraulic lifting frame to steer. An angle sensor on one side of the hydraulic lifting frame precisely monitors and controls the rotation angle. Simultaneous or separate activation of multiple motors allows the hydraulic lifting frame to steer independently, achieving on-the-spot turning. Furthermore, the hydraulic lifting frame allows for adjustment of the support height according to the height of the crops, making it convenient to use and contributing to improved crop quality and efficiency.

[0020] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.
[0021] like Figures 1-4 As shown, this embodiment provides a high-leg steerable agricultural machinery support structure, which includes an agricultural machinery body 1. The agricultural machinery body 1 is provided with a high-leg support steering mechanism 2. The high-leg support steering mechanism 2 includes two support frames 3 symmetrically fixedly installed at the bottom of the agricultural machinery body 1. Two motors 4 are symmetrically fixedly installed at the top of the support frames 3. A gearbox 5 connected to the motors 4 is fixedly installed at the bottom of the support frames 3. A steering column 6 is installed at the bottom of the gearbox 5. A hydraulic lifting frame 7 is provided at one end of the steering column 6. A drive wheel 8 is fixedly installed at the bottom of the hydraulic lifting frame 7. An angle sensor 9 is provided on one side of the hydraulic lifting frame 7. The high-foot support steering mechanism 2 enables the agricultural machinery body 1 to autonomously adjust its steering during operation and precisely control the steering angle. During use, starting the motor 4 causes its output to drive the gears in the gearbox 5, which in turn rotates the steering column 6 via multiple gear sets, thus rotating the hydraulic lifting frame 7. This allows the hydraulic lifting frame 7 to turn, and the angle sensor 9 on one side of the hydraulic lifting frame 7 can precisely monitor and control the rotation angle. Simultaneous or separate starting of multiple motors 4 allows the hydraulic lifting frame 7 to independently turn, achieving the function of turning on the spot. Furthermore, the hydraulic lifting frame 7 can adjust its support height according to the height of the crops, making it convenient to use and helping to improve crop quality and efficiency.
[0022] In this embodiment, as Figures 1-4 As shown, a torque limiter 10 is fixedly installed on the output end of the motor 4 and connected to the transmission shaft on the gearbox 5; the torque limiter 10 can limit the transmission torque and prevent the motor 4 or gearbox 5 from malfunctioning due to excessive steering resistance.
[0023] A connecting sleeve 11 is fixedly installed on the steering column 6, and multiple bolts 12 are evenly installed on the connecting sleeve 11. Multiple threaded holes 13 that mate with the bolts 12 are opened on the connecting end of the hydraulic lifting frame 7. The connecting sleeve 11, bolts 12 and threaded holes 13 are used to install and connect the steering column 6 and the hydraulic lifting frame 7, which improves the overall strength of the steering column 6 and the hydraulic lifting frame 7 after connection and prevents the hydraulic lifting frame 7 and the drive wheel 8 from falling off due to gravity.
[0024] The hydraulic lifting frame 7 has multiple sliding grooves 14, and a protective frame 15 is slidably installed between two sliding grooves 14. A protective cover 16 is fixedly installed on the surface of the hydraulic lifting frame 7. Magnets 17 that attract each other are embedded in the top of the protective frame 15 and the bottom of the protective cover 16. After the protective frame 15 is pushed up and fits against the protective cover 16, it can enclose the angle sensor 9, thus protecting it and preventing crops from directly contacting the angle sensor 9 during operation. After the protective frame 15 and the protective cover 16 are fitted together, the two magnets 17 adhere to each other and attract each other, relying on the resulting attraction to fix the protective frame 15, ensuring a firm connection between the protective frame 15 and the protective cover 16 and preventing it from loosening.
[0025] In this embodiment, as Figures 1-4 As shown, a mounting base 18 is fixedly installed on the hydraulic lifting frame 7. Multiple springs 19 are symmetrically fixedly installed inside the mounting base 18. A locking rod 20 is fixedly installed at one end of the spring 19. Locking blocks 21 are fixedly installed on both sides of the angle sensor 9. The diameter of the locking rod 20 matches the inner diameter of the slot on the locking block 21, and one end of the locking rod 20 is set to be arc-shaped. Angle sensor 9 is mounted on hydraulic lifting frame 7 via mounting base 18 using a locking connection between locking rod 20 and locking block 21. Since the supporting component in the locking connection is spring 19, the locking rod 20 and locking block 21 are movably connected, allowing angle sensor 9 to be detached from mounting base 18. Simply pulling angle sensor 9 causes locking block 21 to press against locking rod 20, causing locking rod 20 to retract and detach from locking block 21 for disassembly. Similarly, during installation, angle sensor 9 is pressed against mounting base 18, causing locking blocks 21 on both sides to press against locking rod 20 for installation. This facilitates maintenance of angle sensor 9. The diameter of locking rod 20 is matched with the inner diameter of locking block 21, resulting in a tighter and more stable connection, preventing angle sensor 9 from shaking. One end of locking rod 20 is arc-shaped, making it easier for locking block 21 to press against locking rod 20 during installation and disassembly.
[0026] like Figures 1-4 As shown, the working process of the high-legged, steerable agricultural machinery support structure provided in this embodiment is as follows:
[0027] Step 1: By starting the motor 4, its output end drives the gears in the gearbox 5 to rotate. Through the transmission of multiple sets of gears, the steering column 6 rotates, which in turn drives the hydraulic lifting frame 7 to rotate, enabling the hydraulic lifting frame 7 to turn. The angle sensor 9 installed on one side of the hydraulic lifting frame 7 accurately monitors and controls the rotation angle. Simultaneously starting multiple motors 4 or starting multiple motors 4 separately can enable the hydraulic lifting frame 7 to complete independent turning, achieving the function of turning on the spot. At the same time, the hydraulic lifting frame 7 can also adjust the support height according to the height of the crops.
[0028] Step 2: After pushing the protective frame 15 up and fitting it with the protective cover 16, it can enclose the angle sensor 9, thus protecting it and preventing crops from directly touching the angle sensor 9 during operation.
[0029] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein. Any modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims.
