Technical Field

[0001] This utility model relates to the field of transport vehicle technology, specifically to an unmanned tracked sugarcane transport vehicle. Background Technology

[0002] Sugarcane is a very important economic crop, and field transportation is a crucial step in the sugarcane harvesting process. Therefore, improving the efficiency of field sugarcane collection and transportation and reducing transportation costs are important issues facing sugarcane transportation. In hilly areas, traditional sugarcane transportation mainly relies on human or animal-powered wheeled vehicles. This method is not only inefficient but also prone to damaging the sugarcane. It also presents several problems, such as the risk of vehicles skidding and overturning on uneven roads, steep slopes, or muddy surfaces, which further damage the sugarcane, reducing its quality and yield. Moreover, with the expansion of sugarcane cultivation, the quantity of sugarcane requiring transportation is also increasing, and traditional transportation methods can no longer meet the demands of large-scale production.

[0003] Currently, tracked transport vehicles on the market still have some problems. Although they enhance adaptability to complex terrain, they are structurally complex, have high maintenance costs, are difficult to operate, and require manual loading and unloading. Furthermore, there is currently no tracked transport vehicle capable of automatically harvesting, loading, unloading, and transporting sugarcane in unmanned fields. Therefore, in-depth research and optimization of the chassis structure of tracked sugarcane field transport vehicles are needed to improve their transportation efficiency and stability, reduce maintenance costs and operational difficulty, and thus better meet the needs of sugarcane transportation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a technical solution: an unmanned tracked sugarcane transport vehicle, including a tracked vehicle body 1. The tracked vehicle body 1 is composed of a chassis frame module, a track module, a loading and unloading module, and a drive module. The chassis frame module is welded from a steel frame 2. The upper end of the steel frame 2 is provided with a loading platform 8. The track module is composed of tracks 4, support rollers 5, guide wheels 6, and drive wheels 7. The loading and unloading module includes an automatic loading rack 9, a loading platform guardrail 11, a loading hydraulic cylinder 10 that drives the automatic loading rack 9, an unloading guardrail hydraulic cylinder 12 that drives the loading platform guardrail 11, and an unloading hydraulic cylinder 13 that drives the loading platform 8. The drive module includes a power battery (not shown), a control cabinet 14, a motor 3, and a hydraulic pump 15. The power battery provides power to the motor to drive the transport vehicle, and also provides power to the hydraulic pump to drive the hydraulic cylinders in the loading and unloading module.

[0021] The tracked vehicle body 1 integrates a microcontroller and a network transmission module connected to the microcontroller's communication interface, enabling remote control and autonomous navigation of the vehicle. The system can autonomously travel according to a preset path. The drive module controls two motors to achieve forward movement and differential steering of the tracked sugarcane transport vehicle. The drive module includes a power battery, control cabinet, motors, and hydraulic pump. The loading and unloading module includes an automatic loading rack 9, a loading platform guardrail 11, a loading hydraulic cylinder 10 that drives the automatic loading rack 9, an unloading guardrail hydraulic cylinder 12 that drives the loading platform guardrail 11, and an unloading hydraulic cylinder 13 that drives the loading platform 8. The automatic loading rack 9 is also equipped with a material support rod 91.

[0022] In a preferred embodiment of this utility model, the automatic loading rack 9 is connected to the upper part of the steel frame 2 via two loading hydraulic cylinders 10, and is also hinged to the front end of the steel frame 2. The loading platform guardrail 11 is connected to the rear end of the loading platform 8 via a hinge and an unloading guardrail hydraulic cylinder 12. The end of the unloading guardrail hydraulic cylinder 12 away from the loading platform guardrail 11 is connected to the steel frame 2 via a hinge. The bottom of the unloading hydraulic cylinder 13 is fixedly connected to the middle of the chassis frame of the tracked vehicle body 1, and the other end of the unloading hydraulic cylinder 13 is connected to the bottom of the loading platform 8 via a hinge. Five sets of support rollers 5 are evenly installed on both sides of the chassis frame of the tracked vehicle body 1, and the support rollers 5 are in contact with the inner side of the bottom end of the track 4. The outer edge of the drive wheel 7 and the inner side of the track 4 are both provided with meshing joints, and the meshing joints of the outer edge of the drive wheel 7 and the inner side of the track 4 are mutually engaged. The front end of the chassis frame of the tracked vehicle body 1 is equipped with a power battery, a control cabinet 14, and a hydraulic pump 15. The hydraulic pump 15 provides hydraulic power to the loading hydraulic cylinder 10, the unloading guardrail hydraulic cylinder 12, and the unloading hydraulic cylinder 13 through hydraulic pipelines.

[0023] The chassis frame module is welded from a steel frame 2. A loading platform 8 is located at the top of the steel frame 2. The steel frame 2, as the main load-bearing structure of the entire vehicle, is formed using high-quality welding processes, ensuring the vehicle's strength and stability. The loading and unloading module uses hydraulic cylinders to drive the automatic loading rack 9, the loading platform 8, and the loading platform guardrail 11 to achieve automatic loading and unloading. This hydraulically driven automatic loading and unloading system significantly improves the level of automation. The module can automatically complete the loading and unloading of sugarcane according to control commands, reducing manpower requirements and improving operational efficiency.

[0024] The drive module uses a power battery to power motor 3, driving the vehicle. Compared to traditional motors, it provides more efficient and stable power output while reducing energy consumption and maintenance costs. The track module consists of tracks 4, track rollers 5, guide rollers 6, and drive wheels 7. This module is the core of the vehicle's adaptability to complex terrain. Tracks 4 are designed to be wear-resistant and evenly distribute the vehicle's weight, reducing pressure on the farmland surface and allowing the vehicle to maintain good passability on soft, muddy, and uneven ground. Track rollers 5 and guide rollers 6 work together to ensure stable track operation and directional control. Drive wheels 7 are connected to brushless motor 3 through a reducer to achieve efficient power transmission. The full-tooth meshing design ensures efficient and stable power transmission and reduces wear and slippage risks.

[0025] See Figure 4 As shown, the microcontroller 100 is installed in the control cabinet 14. The microcontroller 100 is also connected to a relay 101, a network transmission module 103, a wireless remote control receiver module 102, a motor controller 105, a data acquisition module, and a touch screen 103. The microcontroller 100 controls the operation of the loading hydraulic cylinder 10, the unloading guardrail hydraulic cylinder 12, and the unloading hydraulic cylinder 13 through the relay 101. The microcontroller 100 is connected to the motor controller 105, and the motor controller 105 drives the motor 3 through the PWM converter module 106. The data acquisition module in this patent includes a speed sensor 107, a pressure sensor 108, a temperature sensor 109, and a photoelectric sensor 110.

[0026] The speed sensor uses a Hall effect proximity module (model NJK-8002A), and the temperature sensor uses a DHT11 temperature sensor. The speed sensor monitors the forward and turning speeds of the sugarcane transport vehicle chassis in real time. The temperature sensor primarily monitors the temperature of the chassis motor. A spoke-type pressure sensor detects the weight of the sugarcane transport vehicle. A through-beam photoelectric sensor monitors loading and unloading. These sensors transmit the collected data to the microcontroller for processing. A touchscreen facilitates human-machine interaction, allowing operators to input commands to control the sugarcane transport vehicle. The network transmission module uses an onboard Wi-Fi module (model ESP8266-01S). Data received by the microcontroller is transmitted to the monitoring center via the network module, enabling remote monitoring and management of the sugarcane transport vehicle. A wireless remote control receiver module receives information from the remote control and transmits this information to the microcontroller for processing, enabling the sugarcane transport vehicle to move forward, turn, and load / unload.

[0027] Working principle: When using this unmanned tracked sugarcane transport vehicle, the operator first sends a preset driving path and working instructions to the tracked vehicle body 1 via the ESP8266-01s network transmission module (not shown). After receiving the instructions, the microcontroller controls the tracked vehicle body 1 to autonomously drive to the sugarcane field according to the preset path. Upon reaching the loading point, see... Figure 1 As shown, the loading hydraulic cylinder 10 extends outward to drive the automatic loading frame 9 to a horizontal position, and then controls the tracked sugarcane transport vehicle to move forward. The front end of the automatic loading frame 9, like a shovel, lifts the bundle of sugarcane 92. The loading hydraulic cylinder 10 retracts, and the automatic loading frame 9 lifts the bundle of sugarcane upward. The material support rod 91, which is perpendicular to the automatic loading frame 9, restricts the bundle of sugarcane to prevent it from rolling off during the upward movement. See also... Figure 2 As shown, when the automatic loading rack 9 is raised to a certain height (tilted toward the loading platform 8), the bundled sugarcane will slide onto the loading platform 8 due to gravity. Ideally, the bundled sugarcane will be poured to the middle of the loading platform 8 each time, and then slide to the front or back of the loading platform 8 using the round shape of the sugarcane itself. The loading platform guardrail 11 can ensure that the sugarcane will not slip during loading and transportation.

[0028] Repeat the loading process above. When the preset load weight is reached, the tracked sugarcane transport vehicle carries the bundles of sugarcane to the unloading area. When it arrives at the unloading area, see... Figure 3As shown, the unloading guardrail hydraulic cylinder 12 retracts, causing the loading platform guardrail 11 to tilt downwards until it is on the same plane or nearly on the same plane as the upper surface of the loading platform 8. Immediately afterwards, the unloading hydraulic cylinder 13 extends upwards. Since the end of the loading platform 8 near the loading platform guardrail 11 is connected to the steel frame 2 via a hinge, when the unloading hydraulic cylinder 13 extends upwards, it lifts the loading platform 8 upwards. The loading platform 8 is lifted upwards and tilts towards the loading platform guardrail 11. The bundles of sugarcane roll down under their own weight. After the unloading of the bundles of sugarcane is completed, the guardrail hydraulic cylinder 12 extends outwards, and the unloading hydraulic cylinder 13 retracts downwards.

[0029] The above completes one loading and unloading cycle. Repeating these actions facilitates the rapid and bulk transfer of harvested sugarcane from the field to a designated location. This patented unmanned tracked sugarcane transport vehicle is used solely for moving sugarcane from the sugarcane field to a designated centralized loading point.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
