Description

Technical Field

[0001] This utility model belongs to the technical field of agricultural vehicle components, specifically relating to a flatbed chassis for an unmanned agricultural vehicle. Background Technology

[0002] With the continuous development of mechanical technology, agricultural vehicles, as a type of cargo vehicle suitable for agricultural transportation and other uses, are becoming increasingly popular in many villages in my country. At present, agricultural vehicles are widely used in farming and field operations. The chassis, as an important component that supports and installs the engine and other parts and assemblies of the agricultural vehicle, plays an important role in the overall shape of the agricultural vehicle, receiving power from the engine, and maintaining normal driving.

[0003] Existing small agricultural vehicles have storage boxes fixedly installed on the top of the chassis for transporting crops. However, the uneven road surface in rural areas causes significant vibrations during vehicle operation. These vibrations can cause the crops in the storage box to be squeezed and collided, leading to damage or a decline in quality. This is especially true for delicate fruits or vegetables, where vibrations can cause appearance defects or premature rotting, increasing crop losses and resulting in economic losses.

[0004] Therefore, there is a need for a flatbed chassis for unmanned agricultural vehicles to solve the problem that existing agricultural vehicles generate significant vibrations during operation, increasing crop losses. Utility Model Content

[0005] The purpose of this utility model is to provide a flatbed chassis for agricultural unmanned vehicles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flatbed chassis for an agricultural unmanned vehicle, comprising a chassis frame, two front wheels rotatably mounted near the front end of the chassis frame, two rear wheels rotatably mounted near the rear end of the chassis frame, a drive assembly corresponding to the two rear wheels located near the rear end of the chassis frame, a steering assembly corresponding to the two front wheels located near the front end of the chassis frame, an electrical distribution box mounted on the top of the chassis frame, two shock-absorbing mechanisms located on the top of the chassis frame, and storage boxes fixedly connected to the tops of the two shock-absorbing mechanisms.

[0007] It should be noted in the solution that both front wheel surfaces and both rear wheel surfaces are fixedly connected with evenly distributed herringbone-shaped anti-slip strips.

[0008] It is worth noting that a gearbox corresponding to the drive assembly is installed at the bottom of the chassis frame.

[0009] Furthermore, it should be noted that the shock absorption mechanism includes two arc-shaped support frames fixedly connected to the top of the chassis frame and two buffer seats fixedly connected to the bottom of the storage box. A round rod is fixedly connected between the two arc-shaped support frames. Two tube sleeves are slidably connected to the outer wall of the round rod. A transverse shock absorption spring is fixedly connected between the two tube sleeves. A first connecting lug is fixedly connected to the top of each of the two tube sleeves. A connecting rod is rotatably connected to the top of each of the two first connecting lugs. A second connecting lug is rotatably connected to the top of each of the two connecting rods. A damping rod is installed on the inner wall of the bottom of each of the two buffer seats. A longitudinal shock absorption spring is sleeved on the outer wall of each of the two damping rods.

[0010] In a preferred embodiment, the transverse damping spring is sleeved on the outer wall of the round rod.

[0011] In a preferred embodiment, the longitudinal damping spring is fixedly connected between the bottom of the buffer seat and the top of the arc-shaped support frame.

[0012] Compared with the prior art, the flatbed chassis for an agricultural unmanned vehicle provided by this utility model has at least the following beneficial effects:

[0013] (1) By setting up a shock-absorbing mechanism, the transverse shock-absorbing spring and the longitudinal shock-absorbing spring work together. Under the action of the buffer seat and the damping rod, the vibration of the chassis frame can be buffered. This can effectively reduce the transmission of vibration from the chassis frame to the storage box, making the vehicle drive more smoothly and improving the stability and safety of crops during transportation. This can prevent crops from being squeezed, collided and damaged during transportation. In particular, for fragile fruits and vegetables, it can maintain their shape and quality and reduce the loss rate.

[0014] (2) By setting herringbone anti-skid strips on the tire surface, the traction between the tire and the ground can be effectively enhanced, providing better grip on uneven rural roads, so that the vehicle can drive better on muddy or slippery roads and avoid slipping and loss of control; at the same time, a gearbox is set up so that farmers can dynamically adjust the speed of the vehicle according to the actual situation, thereby adapting to the sowing speed of different crops, making the operation of the vehicle more flexible and accurate.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Please see Figure 1-4 This utility model provides a flatbed chassis for an agricultural unmanned vehicle, including a chassis frame 1. Two front wheels 2 are rotatably mounted on the bottom of the chassis frame 1 near the front end, and two rear wheels 3 are rotatably mounted on the bottom of the chassis frame 1 near the rear end. A drive assembly 4 corresponding to the two rear wheels 3 is provided on the bottom of the chassis frame 1 near the rear end, and a steering assembly 5 corresponding to the two front wheels 2 is provided on the bottom of the chassis frame 1 near the front end. An electrical distribution box 6 is installed on the top of the chassis frame 1, and two shock-absorbing mechanisms 7 are provided on the top of the chassis frame 1. A storage box 8 is fixedly connected to the top of the two shock-absorbing mechanisms 7.

[0022] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that both front wheels 2 and both rear wheels 3 are fixedly connected with evenly distributed herringbone-shaped anti-skid strips. This herringbone design effectively enhances tire traction, providing better grip on uneven rural roads, allowing the vehicle to drive better on muddy or slippery surfaces, preventing skidding and loss of control. The herringbone strips also help the agricultural vehicle steer and control more accurately, providing better lateral stability during turns and reducing directional control problems caused by loss of traction. This allows the driver to drive the vehicle more easily on narrow or winding rural roads. Simultaneously, the herringbone design helps reduce tire wear because it distributes contact surface and pressure more evenly, extending tire lifespan and reducing maintenance and replacement costs. In various road conditions, the herringbone strips ensure the vehicle can pass smoothly, whether on slopes, muddy farmland, or overgrown areas. This design effectively improves the vehicle's passability and enhances its ability to cope with complex environments.

[0023] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that a gearbox corresponding to the drive assembly 4 is installed at the bottom of the chassis frame 1. Different crops or different soil conditions may require different sowing speeds. The gearbox can adjust the vehicle speed according to specific sowing needs, thereby optimizing sowing efficiency. In open areas or when large-scale sowing is required, a higher speed can be selected to increase productivity, while in narrow areas or areas requiring delicate operation, a lower speed can be selected to ensure sowing quality and precision. The gearbox allows farmers to dynamically adjust the speed of the vehicle according to the actual situation. In different field operation environments, different obstacles, terrain, and vegetation conditions may be encountered, all of which will affect the optimal sowing speed. The gearbox can be adjusted at any time according to needs, making the operation of the vehicle more flexible and adaptable. At the same time, selecting an appropriate speed can help reduce the energy consumption of the vehicle. In delicate operations that require lower speeds, the vehicle can complete the task with more economical energy consumption, improving energy utilization efficiency. In large-area sowing tasks, rapid sowing can complete the operation faster and reduce overall energy consumption.

[0024] As can be seen from the above working process, by setting herringbone anti-slip strips on the surfaces of the front wheel 2 and the rear wheel 3, the traction between the tires and the ground can be effectively enhanced. On uneven rural roads, it can provide better grip, allowing the vehicle to drive better on muddy or slippery roads and avoid slipping and loss of control. At the same time, a gearbox is set up, allowing farmers to dynamically adjust the speed of the vehicle according to the actual situation, thereby adapting to the sowing speed of different crops and making the operation of the vehicle more flexible and accurate.

[0025] Further as Figure 4 As shown, it is worth noting that the shock absorption mechanism 7 includes two arc-shaped support frames 701 fixedly connected to the top of the chassis frame 1 and two buffer seats 708 fixedly connected to the bottom of the storage box 8. A round rod 702 is fixedly connected between the two arc-shaped support frames 701. Two tube sleeves 703 are slidably connected to the outer wall of the round rod 702. A transverse shock absorption spring 704 is fixedly connected between the two tube sleeves 703. A first connecting ear 705 is fixedly connected to the top of each of the two tube sleeves 703. A connecting rod 706 is rotatably connected to the top of each of the two first connecting ears 705. A connecting rod 706 is rotatably connected to the top of each of the two connecting rods 706. The vehicle is rotatably connected with a second connecting ear 707. Damping rods 709 are installed on the inner walls of the bottom of both buffer seats 708. Longitudinal damping springs 710 are sleeved on the outer walls of both damping rods 709. By setting up the damping mechanism 7, the transmission of vibration from the chassis frame 1 to the storage box 8 can be effectively reduced, making the vehicle drive more smoothly and improving the stability and safety of crops during transportation. This can prevent crops from being squeezed, collided and damaged during transportation. In particular, for fragile fruits and vegetables, it can maintain their shape and quality and reduce the loss rate.

[0026] Further as Figure 4 As shown, it is worth noting that the transverse damping spring 704 is sleeved on the outer wall of the round rod 702 to buffer the vibrations received by the chassis frame 1 and prevent the crops inside the storage box 8 from shaking and being damaged by the vibrations.

[0027] Further as Figure 4 As shown, it is worth noting that the longitudinal damping spring 710 is fixedly connected between the bottom of the buffer seat 708 and the top of the arc-shaped support frame 701. The damping rod 709 and the longitudinal damping spring 710 work together to further buffer the vibration impact on the chassis frame 1, thereby improving the reliability and stability of the vehicle.

[0028] This solution has the following working process: In actual use, the power distribution box 6 drives the drive assembly 4 to provide driving force to the rear wheels 3, and the steering assembly 5 provides steering force to the front wheels 2. Under the action of the gearbox, the farmer dynamically adjusts the speed of the vehicle according to the actual situation. When passing through uneven road surfaces, the lateral damping spring 704 and the longitudinal damping spring 710 cooperate, and under the action of the buffer seat 708 and the damping rod 709, they can buffer the vibration of the chassis frame 1, which can effectively reduce the transmission of vibration from the chassis frame 1 to the storage box 8.

[0029] In summary: By installing herringbone anti-slip strips on the surfaces of the front wheels 2 and rear wheels 3, the traction between the tires and the ground can be effectively enhanced, providing better grip on uneven rural roads. This allows the vehicle to drive better on muddy or slippery surfaces, preventing skidding and loss of control. Simultaneously, the inclusion of a gearbox allows farmers to dynamically adjust the vehicle's speed according to actual conditions, adapting to the sowing speed of different crops and making the vehicle's operation more flexible and accurate. The shock absorption mechanism 7 effectively reduces the transmission of vibrations from the chassis frame 1 to the storage box 8, resulting in smoother vehicle operation and improved stability and safety of crops during transportation. This prevents crops from being excessively squeezed, collided, and damaged during transport, especially for fragile fruits and vegetables, maintaining their shape and quality and reducing losses.
