Description

Technical Field

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

[0002] Agricultural mechanization is becoming increasingly widespread, with many farms using mechanized operations to improve efficiency and crop yields. Agricultural rail transport, as a crucial part of farm operations, primarily handles the transport of agricultural products and fertilizers. However, current agricultural rail transport has the following shortcomings: most railcars can only operate on rails, requiring a change of transport vehicle when goods need to be transported by road. This change of transport not only incurs additional time and manpower, leading to a decrease in overall logistics efficiency, but also increases the accumulated costs of labor and equipment involved. Utility Model Content

[0003] This utility model provides an agricultural rail transport system that has the advantage of being able to transport goods on both rails and roads simultaneously.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An agricultural rail transport system includes: a frame assembly with wheels at its bottom; and a tie rod bracket mounted on the frame assembly; the bottom of the tie rod bracket has a steering wheel, and both the steering wheel and the wheels have track grooves that cooperate with the track; the tie rod bracket is rotatably connected to the frame assembly via a steering assembly, so that the tie rod bracket can rotate relative to the frame assembly and drive the steering wheel to turn.

[0006] Using the aforementioned technical solution, the frame assembly is equipped with a tie rod bracket, and the bottom of the frame assembly is equipped with a travel wheel for traveling on the road. The bottom of the tie rod bracket is equipped with a steering wheel that can be used not only for traveling on the road but also for steering. Both the steering wheel and the travel wheel have track grooves for cooperating with the track. The tie rod bracket is equipped with a steering component that can change the direction of the steering wheel. The tie rod bracket is rotatably connected to the frame assembly. When traveling on the road, rotating the steering component drives the steering wheel to change direction, thus realizing that it can travel on the road and work on the track at the same time.

[0007] Furthermore, the agricultural rail transport system also includes a tie rod pivotally connected to the tie rod bracket.

[0008] By adopting the aforementioned technical solution, since the tie rod is pivotally connected to the tie rod bracket, the tie rod can rotate relative to the tie rod bracket. This allows the operator to adjust the angle and position of the tie rod as needed. By operating the tie rod, the steering component can be driven to change the direction of the steering wheels, allowing for more flexible control of the vehicle's direction and speed.

[0009] Furthermore, the agricultural rail transport system also includes a rod anti-rotation structure formed by the cooperation of the rod bracket and the rod. One of the rod bracket and the rod is provided with a pivot shaft, and the other is provided with a sliding groove that slides with the pivot shaft. The rod anti-rotation structure locks or unlocks the rod by the extension and retraction of the rod along the extension direction of the sliding groove.

[0010] Using the aforementioned technical solution, one of the tie rod bracket and the tie rod is provided with a pivot shaft, and the other is provided with a sliding groove, allowing the pivot shaft to slide within the sliding groove. When the pivot shaft slides along the sliding groove to the locked position, the tie rod anti-rotation structure restricts the rotation of the tie rod, locking it at a fixed angle and preventing free rotation. This state is suitable for travel on tracks, providing a stable travel direction. When the pivot shaft slides along the sliding groove to the unlocked position, the tie rod anti-rotation structure releases the restriction on the rotation of the tie rod, allowing it to rotate freely, increasing operational flexibility and making it suitable for applications where frequent changes in travel direction may be required when traveling on highways.

[0011] Furthermore, the anti-rotation structure of the pull rod includes an insertion part provided on one of the pull rod bracket and the pull rod, and a receiving part provided on the other. The receiving part has a limiting hole, and the extension and retraction of the pull rod along the extension direction of the groove causes the insertion part to enter or exit the limiting hole.

[0012] Using the aforementioned technical solution, the pull rod anti-rotation structure limiting tube includes an insertion part located on one of the pull rod bracket and the pull rod, and a receiving part located on the other. It has a limiting hole inside. When locked, the insertion part is inserted into the limiting hole and fixed by the pull rod anti-rotation structure, achieving the locked state of the pull rod. As the pull rod slides, when it unlocks, the insertion part, originally inserted into the limiting hole, will disengage from the limiting hole, and the pull rod is no longer restricted by the pull rod anti-rotation structure, allowing it to rotate.

[0013] Furthermore, the groove extends axially on the side wall of the socket, and the pivot shaft is connected to the insertion part.

[0014] Using the aforementioned technical solution, the slide extends along the axial direction of the socket, allowing the pivot shaft to slide along the axial direction of the slide. The pivot shaft is connected to one end of the pull rod, and when the pull rod is in the unlocked position, it can rotate around the pivot shaft. Furthermore, the pivot shaft not only allows the pull rod to slide in the slide, but also allows the pull rod to rotate in the second position, increasing its flexibility and practicality.

[0015] Furthermore, the tie rod rotates relative to the tie rod bracket in a vertical plane.

[0016] Using the aforementioned technical solution, when driving on the highway, it is necessary to frequently adjust the angle of the tie rod to adapt to different road conditions and driving needs. The rotation of the tie rod in the vertical plane makes this adjustment simple and direct, which simplifies the structure of the system and reduces manufacturing costs and maintenance difficulty.

[0017] Furthermore, the steering assembly includes a fixed turntable, a movable turntable, and a rotating shaft; the frame assembly includes a frame; the fixed turntable is connected to the frame; the movable turntable is connected to the tie rod bracket; the rotating shaft passes through the fixed turntable and the movable turntable; and the fixed turntable and the movable turntable rotate relative to each other around the rotating shaft.

[0018] Using the aforementioned technical solution, the steering assembly consists of a fixed turntable, a movable turntable, and a rotating shaft, realizing the relative rotation between the vehicle frame and the steering assembly. The fixed turntable is fixedly connected to the vehicle frame, and the movable turntable is fixedly connected to the tie rod bracket. The rotating shaft passes through the fixed turntable and the movable turntable to form the central axis of their relative rotation. When the operator applies force to the tie rod bracket through the tie rod, the movable turntable rotates relative to the fixed turntable, so that the relative rotation between the vehicle frame and the steering assembly also occurs along the rotating shaft, thereby enabling the change of driving direction to achieve the purpose of steering.

[0019] Furthermore, the traveling wheel includes at least one drive wheel with a hub motor.

[0020] By adopting the aforementioned technical solution, at least one drive wheel is used, and the walking wheel is equipped with a power source, which can autonomously generate driving force to propel the entire system forward. The addition of drive wheels improves the flexibility of the agricultural rail transport system, and the travel speed can be autonomously controlled as needed.

[0021] Furthermore, the diameter of the traveling wheel is larger than the diameter of the steering wheel.

[0022] Using the aforementioned technical solution, a tie rod bracket is provided under the vehicle frame, and a steering wheel is provided under the tie rod bracket. The travel wheel is directly located under the vehicle frame. Therefore, in order to maintain the balance of the system, the diameter of the travel wheel is made larger than the diameter of the steering wheel.

[0023] Furthermore, the frame assembly is provided with a power bracket for mounting the power supply unit. The power bracket is detachably connected to the lower part of the frame assembly. The power supply unit is provided with a charging port and a control panel. The frame assembly is provided with clearance holes corresponding to the charging port and the control panel.

[0024] By adopting the aforementioned technical solution, the power bracket is detachably connected to the lower end of the frame assembly, making the installation and removal of the power component very convenient. This facilitates user maintenance, shortens maintenance time, and improves maintenance efficiency. Secondly, the detachable design also enhances the system's flexibility, allowing users to adjust the configuration of the power component according to specific application needs. The frame assembly is equipped with clearance holes corresponding to the charging port and control panel, ensuring that the charging port and control panel can be smoothly exposed on the frame assembly. This eliminates the need to remove the power component from the power bracket during charging, improving the convenience of user operation. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 and Figure 2As shown, an agricultural rail transport system 1 includes: a frame assembly 11 with a traveling wheel 111 at its bottom; and a tie rod bracket 12 mounted on the frame assembly 11; the bottom of the tie rod bracket 12 is provided with a steering wheel 124, and both the steering wheel 124 and the traveling wheel 111 are provided with a track groove 119 that cooperates with the track; the tie rod bracket 12 is rotatably connected to the frame assembly 11 through a steering assembly, so that the tie rod bracket 12 can rotate relative to the frame assembly 11 and drive the steering wheel 124 to turn.

[0037] Understandably, the frame assembly 11 is equipped with a tie rod bracket 12, and the bottom of the frame assembly 11 is equipped with a travel wheel 111 for road travel. The bottom of the tie rod bracket 12 is equipped with a steering wheel 124 that can be used not only for road travel but also for steering. Both the steering wheel 124 and the travel wheel 111 have track grooves 119 for engaging with the track 14. Figure 2 The diagram only shows the structure of the track groove 119 (not limited to the difference between the traveling wheel 111 and the steering wheel 124). The tie rod bracket 12 is equipped with a steering component that can change the direction of the steering wheel 124. The tie rod bracket 12 is rotatably connected to the frame assembly 11. When driving on the road, the steering component is rotated to drive the rotating wheel to change direction, thus realizing that it can drive on the road and work on the track.

[0038] Optionally, the frame assembly 11 includes a frame 112 and a body shell 113. The body shell 113 is positioned above the frame 112 and fixedly connected to the frame 112, for example, by bolts and nuts or snap-fit ​​connections. To ensure the stability of the entire vehicle body, the frame 112 is generally made of metal. In this embodiment, to reduce costs and make the entire vehicle body lighter, the body shell 113 is made of hard plastic.

[0039] In one embodiment, such as Figure 3 As shown, the traveling wheel 111 includes at least one drive wheel 111a with a hub motor, serving as an electric version of the agricultural rail transport system.

[0040] It is understandable that by using at least one drive wheel, the walking wheel 111 is equipped with a power source, which can autonomously generate driving force to propel the entire system forward. The addition of the drive wheel improves the flexibility of the agricultural rail transport system 1, and the travel speed can be autonomously controlled as needed.

[0041] Preferably, hub motors are used to drive the wheels.

[0042] In another embodiment, such as Figure 4 As shown, in order to save costs, the drive wheels can also be replaced with ordinary wheels 111b, as an economical option for agricultural rail transport systems.

[0043] Optional, such as Figure 1 As shown, the diameter of the traveling wheel 111 is larger than the diameter of the steering wheel 124.

[0044] It is understandable that a tie rod bracket 12 is provided below the frame 112, a steering wheel 124 is provided below the bracket of the tie rod 125, and the travel wheel 111 is directly provided below the frame 112. Therefore, in order to maintain the balance of the system, the diameter of the travel wheel 111 is larger than the diameter of the steering wheel 124.

[0045] Optionally, in this embodiment, there are two walking wheels 111, which are located below the frame 112. One of them is a drive wheel, located at the rear of the agricultural rail transport system 1 (the side with the tie rod bracket 12 is the front). There are two steering wheels 124, which are located at the lower end of the tie rod bracket 12.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, both the traveling wheel 111 and the steering wheel 124 are composed of bolts, washers, bearings, wheels, nuts, etc., and are assembled together by bolts and fixed to the wheel frame.

[0047] Preferably, the agricultural rail transport system 1 has a built-in detachable and modular track 14, which is fixed to the vehicle body 113 by straps. When working in the field, the detachable and modular track 14 is first removed from the vehicle body 113 and laid in the field. Then, the agricultural rail transport system 1 can transport agricultural products and other materials on the detachable and modular track 14. Both the steering wheel 124 and the traveling wheel 111 have track grooves 119 that can be used to cooperate with the track. Through the cooperation of the track grooves 119 and the track, the agricultural rail transport system 1 can transport more smoothly. When it is necessary to transport crops on the road, the agricultural rail transport system 1 can drive directly on the road, so as to realize two usage modes: working in the field and transporting on the road.

[0048] Based on the above embodiments, such as Figure 5 As shown, the agricultural rail transport system 1 also includes a tie rod 125 pivotally connected to the tie rod bracket 12.

[0049] Understandably, since the tie rod 125 is pivotally connected to the tie rod bracket 12, the tie rod 125 can rotate relative to the tie rod bracket 12, allowing the operator to adjust the angle and position of the tie rod 125 as needed. By operating the tie rod 125, the steering assembly can be driven to change the direction of the steering wheel 124, allowing for more flexible control of the transport vehicle's direction and speed.

[0050] Optionally, in one embodiment, the agricultural rail transport system 1 further includes a rod anti-rotation structure formed by the cooperation of the rod bracket 12 and the rod 125. The rod 125 is provided with a pivot shaft 126, and the rod bracket 12 is provided with a groove 127 that slides with the pivot shaft 126. The rod anti-rotation structure locks or unlocks the rod 125 by the extension and retraction of the rod 125 along the extension direction of the groove 127.

[0051] It is understood that the pull rod 125 is provided with a pivot shaft 126, and the pull rod bracket 12 is provided with a slide groove 127 that slides with the pivot shaft 126, so that the pivot shaft 126 can slide within the slide groove 127. When the pivot shaft 126 slides along the slide groove 127 to the locked position, the pull rod anti-rotation structure restricts the rotation of the pull rod 125, and the pull rod 125 is locked at a fixed angle and cannot rotate freely. This state is suitable for travel on the track, so that it has a stable travel direction when traveling on the track. When the pivot shaft 126 slides along the slide groove 127 to the unlocked position, the pull rod anti-rotation structure releases the restriction on the rotation of the pull rod 125, and the pull rod 125 can rotate freely, increasing the flexibility of operation and being suitable for the need to frequently change the travel direction when traveling on the highway.

[0052] In another embodiment, the tie rod bracket 12 is provided with a pivot shaft 126, and the tie rod 125 is provided with a sliding groove 127 that slides with the pivot shaft 126, which can also achieve the above effect. The specific operation process will not be described in detail.

[0053] Optionally, the pull rod 125 can rotate in a vertical plane relative to the pull rod bracket 12.

[0054] Understandably, when driving on the highway, the angle of the tie rod 125 needs to be frequently adjusted to adapt to different road conditions and driving needs. The rotation of the tie rod 125 in the vertical plane makes this adjustment simple and direct, which simplifies the structure of the system and reduces manufacturing costs and maintenance difficulty.

[0055] In one embodiment, such as Figure 6 , Figure 7 and Figure 8 As shown, the anti-rotation structure of the pull rod includes a socket 121 provided on the pull rod bracket 12 and an insertion part 128 provided on the pull rod 125. The socket 121 has a limiting hole 122. The extension and retraction of the pull rod 125 along the extension direction of the slide groove 127 causes the insertion part 128 to enter or exit the limiting hole 122.

[0056] Understandably, the pull rod anti-rotation structure limiting tube includes a socket portion 121 on the pull rod bracket 12 and an insertion portion 128 on the pull rod 125. It has a limiting hole 122 inside. When locked, the insertion portion 128 is inserted into the limiting hole 122 and fixed by the pull rod anti-rotation structure, achieving the locked state of the pull rod 125. As the pull rod 125 slides, when it unlocks, the insertion portion 128, originally inserted into the limiting hole 122, will disengage from the limiting hole 122, and the pull rod 125 will no longer be restricted by the pull rod anti-rotation structure, allowing it to rotate.

[0057] Furthermore, the groove 127 extends axially on the side wall of the receiving portion 121, and the pivot shaft 126 is connected to the insertion portion 128.

[0058] It is understandable that the slide groove 127 extends axially along the socket portion 121, allowing the pivot shaft 126 to slide axially along the slide groove 127. The pivot shaft 126 is connected to one end of the pull rod 125. When the pull rod 125 is in the unlocked position, it can rotate around the pivot shaft 126. Furthermore, it can be seen that the pivot shaft 126 can not only allow the pull rod 125 to slide in the slide groove 127, but also allow the pull rod 125 to rotate in the second position, increasing its flexibility and practicality.

[0059] Preferably, the pivot shaft 126 can be made of bolts.

[0060] Specifically, the pull rod 125 has two operating modes. When the agricultural rail transport system 1 is transported on a road, the pull rod 125 is in the second position. Lifting the pull rod 125 causes the bolt to slide to the top of the slide groove 127. At this time, the pull rod 125 disengages from the limiting hole 122 and can rotate in the vertical plane around the bolt as the axis, making it convenient for the agricultural rail transport system 1 to turn. Optionally, when the pull rod 125 rotates to 90°, the pull rod 125 abuts against the side wall of the socket 121, which is convenient for personnel to operate. When the agricultural rail transport system 1 is transported on the track, it only needs to travel along the track, so it does not need to turn. At this time, the pull rod 125 is in the first position, and the bolt slides to the bottom of the slide groove 127. At this time, it is restricted by the socket 121 and the pull rod 125 cannot rotate.

[0061] In another embodiment, a groove 127 is provided in the insertion part 128, which is also one end of the pull rod 125. The pivot shaft 126 is fixed on the receiving part 121. The above effect can also be achieved by sliding the insertion part 128 up and down relative to the pivot shaft 126.

[0062] Specifically, such as Figure 8As shown, the steering assembly includes a fixed turntable 131, a movable turntable 132, and a rotating shaft 133. The frame assembly 11 includes a frame 112. The fixed turntable 131 is connected to the frame 112, the movable turntable 132 is connected to the tie rod bracket 12, and the rotating shaft 133 passes through the fixed turntable 131 and the movable turntable 132. The fixed turntable 131 and the movable turntable 132 rotate relative to each other around the rotating shaft 133.

[0063] Understandably, the steering assembly consists of a fixed turntable 131, a movable turntable 132, and a rotating shaft 133, enabling relative rotation between the frame 112 and the steering assembly. The fixed turntable 131 is fixedly connected to the frame 112, and the movable turntable 132 is fixedly connected to the tie rod bracket 12. The rotating shaft 133 passes through the fixed turntable 131 and the movable turntable 132 to form the central axis of relative rotation between them. When the operator applies force to the tie rod bracket 12 through the tie rod 125, the movable turntable 132 rotates relative to the fixed turntable 131, so that the relative rotation between the frame 112 and the steering assembly also occurs along the rotating shaft 133, thereby enabling the change of driving direction to achieve the purpose of steering.

[0064] Optionally, the rotating shaft 133 is a bolt in this embodiment.

[0065] Specifically, the fixed turntable 131 in the steering structure is welded to the front of the frame 112, located above the movable turntable 132, and is mainly used to fix the position of the steering structure. The movable turntable 132 is welded to the tie rod bracket 12. Rotating the tie rod 125 causes the movable turntable 132 to rotate, controlling the direction of travel of the transport vehicle. The entire steering structure is fixed together from top to bottom with bolts, which hold the fixed turntable 131, the movable turntable 132, the washer, and the nut together, allowing the movable turntable 132 and the fixed turntable 131 to rotate along the axial direction of the bolts.

[0066] Furthermore, such as Figure 9 and Figure 10 As shown, the frame assembly 11 is provided with a power bracket 114 for mounting the power supply unit 15. The power bracket 114 is detachably connected to the lower part of the frame assembly 11. The power supply unit 15 is provided with a charging port 151 and a control panel 152. The frame assembly 11 is provided with clearance holes 115 corresponding to the charging port 151 and the control panel 152.

[0067] Understandably, the power bracket 114 is detachably connected to the lower end of the frame assembly 11, making the installation and removal of the power unit 15 very convenient, facilitating user maintenance, shortening maintenance time, and improving maintenance efficiency. Secondly, the detachable design also improves the flexibility of the system, allowing users to adjust the configuration of the power unit 15 according to specific application needs. The frame assembly 11 is provided with clearance holes 115 corresponding to the charging port 151 and the control panel 152, ensuring that the charging port 151 and the control panel 152 can be smoothly exposed on the frame assembly 11, eliminating the need to remove the power unit 15 from the power bracket 114 when charging, thus improving the convenience of user operation.

[0068] Optionally, the power supply bracket 114 is provided with a suspension part 116, which can be directly suspended under the frame 112 and is easy to disassemble. In other embodiments, a bolt and nut connection method can also be used.
