Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery equipment, in particular to a multifunctional remote-controlled transport vehicle. Background Art

[0002] With the development of modern agriculture, farmland operations have become increasingly mechanized, and various agricultural machinery has played a significant role in improving production efficiency and reducing labor intensity. Traditional agricultural transport equipment, mostly manually operated or semi-automated, has met operational needs to a certain extent, but it still has many shortcomings. This is especially true for operations such as spraying, harvesting, and transporting crops across large farmlands. Existing equipment has significant limitations in flexibility, efficiency, and crop protection.

[0003] Traditional agricultural transport vehicles have several limitations in agricultural operations, impacting their overall efficiency and practicality. First, they often use fixed spray systems with limited spraying ranges and non-adjustable angles. This can easily lead to uneven spraying, wasted or missed sprays, and suboptimal spraying results. Furthermore, these spray systems often lack intelligent control, requiring extensive manual operation and increasing the workload for farmers. Second, when transporting agricultural products, the relatively simple structure of traditional transport vehicles makes them difficult to adapt to diverse farmland environments. For example, on slippery or muddy surfaces, a single drive system makes it difficult for the vehicle to maintain stable operation, making it prone to getting stuck and reducing transport efficiency.

[0004] At the same time, the speed of these transport vehicles is usually not adjustable, and they cannot be flexibly adjusted to different operational requirements and terrain conditions, further affecting operational efficiency. In addition, traditional transport vehicles have limited carrying capacity, and loading and unloading operations are cumbersome and complex, which affects overall operational efficiency. Finally, traditional transport vehicles do not provide adequate protection for crops during operation, especially when crossing densely cropped areas, which can easily cause crushing or mechanical damage to crops, not only affecting crop yield and quality, but also potentially causing unnecessary economic losses. Utility Model Content

[0005] To address the aforementioned issues with conventional transport vehicles, such as suboptimal spraying effectiveness, a relatively simple structure, unadjustable speed, and the tendency to crush or mechanically damage crops, this utility model aims to provide a multifunctional, remote-controlled transport vehicle. Through its innovative structural design, this device significantly improves the accuracy and coverage of agricultural transport vehicles during pesticide spraying operations, while also enhancing the equipment's maneuverability and stability on complex terrain. Furthermore, the improved drive system and intelligent control functions significantly reduce crop damage and reduce operational complexity and labor intensity.

[0006] The main idea of ​​the technical solution adopted by this utility model is: the device installs a spraying mechanism with adjustable angle and range on the agricultural transport vehicle body, so that pesticides can be sprayed more evenly and accurately, reducing waste and omissions; and introduces an intelligent control system that can automatically adjust the spraying parameters and vehicle speed according to actual operation needs, reducing the difficulty of operation and improving work efficiency. In addition, the drive device of the transport vehicle is designed as a multi-drive mode, which cooperates with the clamping rod and chain adjustment assembly under the vehicle body to enhance the vehicle's passability and stability on complex terrain and avoid the occurrence of vehicle getting stuck. Finally, this device changes the tilt angle of the box body by setting an adjustment rod that is telescopically controlled by a motor, thereby achieving crop harvesting.

[0010] Furthermore, the chain adjustment assembly includes a connecting ring, the driving wheel assembly includes a rotating shaft, one end of the rotating shaft is sleeved with a connecting ring, and the other end is sleeved with a sprocket, and the chain is engaged with the sprocket.

[0011] Through the above technical solution, the chain adjustment assembly further includes a fixed plate, which is fixedly connected to the inner wall of the clamping rod, an adjusting rod is connected to the fixed plate, a connecting ring is connected to the end of the adjusting rod, and an adjusting bolt for changing the axial position of the adjusting rod is connected to the lower part of the fixed plate.

[0012] Furthermore, the spraying mechanism includes a positioning plate installed on the loading box, a support plate is installed at the lower part of the positioning plate, and a spraying component with an adjustable spraying angle and a drive motor are provided on the support plate.

[0013] Furthermore, the spray assembly includes a slide rail arranged on the upper part of the fixed plate and a spray pipe rotatably connected to the support end. A connecting rod is installed at the free end of the spray pipe, and a slider is provided at the other end of the connecting rod. The slider slides on the slide rail.

[0014] Furthermore, the pipe reel device includes a pipe reel shaft rotatably connected to one side of the vehicle body and a pipe reel motor arranged inside the vehicle body. A pipe reel chain is connected to the output shaft of the pipe reel motor, and the other end of the pipe reel chain is connected to the end of the pipe reel shaft.

[0015] By adopting the above technical solution, the utility model has the following technical effects:

[0016] By setting up a spray mechanism with adjustable angle and range, more uniform and precise pesticide spraying can be achieved, effectively reducing problems such as uneven spraying, pesticide waste, and omissions.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments, rather than all the embodiments.

[0033] refer to Figure 1-12 The present application discloses a multifunctional remote-controlled transport vehicle, including a driving device 1, the driving device 1 including a chain adjustment component 11 for adjusting the tightness of the chain, a hose reel device 4 installed on the side wall of the driving device 1, and a loading box 2 rotatably connected to the driving device 1, and a spraying mechanism 3 for adjusting the spraying angle is provided on the loading box 2.

[0034] like Figure 1 The loading box 2 includes a box body 21 and a telescopic rod 22. The box body 21, consisting of a main body 211 and a lid 212, is used to store harvested items or other materials. The box body 211 is a rectangular structure made of durable metal or composite materials, capable of withstanding heavy weight and impact. The lid 212 is hingedly connected to the box body 211 via a rotating rod 213.

[0035] Specifically, the rotating rod 213 is arranged on one side of the upper part of the box body 21 near the box cover 212 and is fixed to both sides of the box body 211 by a bracket. The rotating rod 213 is made of high-strength alloy material and can withstand the stress of the box cover 212 during the opening and closing process, ensuring its stability during long-term use. The telescopic rod 22 is the main component that drives the box body 21 to tilt and is installed between the vehicle body 12 and the box body 21. The telescopic rod 22 is composed of an electric telescopic rod 22, one end of which is fixed to the vehicle body 12 and the other end is connected to the bracket at the bottom of the box body 21. The telescopic rod 22 can be controlled to extend and retract by a motor, thereby changing the tilt angle of the box body 21.

[0036] It's worth noting that when the harvested items within box 21 need to be unloaded, the control system extends telescopic rod 22, gradually tilting box 21 to one side. As box 21 tilts, lid 212 automatically rotates downward under gravity, opening via rotating rod 213 to allow the harvested items to be poured out. Once box 21 returns to a horizontal position, lid 212 recloses under the action of rotating rod 213, ensuring box 21 remains airtight when not unloading.

[0037] It is worth mentioning that the telescopic rod 22 is connected to the piston rod of the hydraulic cylinder 23 through a solid connector to achieve telescopic movement. The hydraulic cylinder 23 is fixed to the vehicle body 12 and can accurately adjust the movement speed and stroke of the telescopic rod 22.

[0038] Specifically, the hydraulic cylinder 23 is connected to the bottom of the telescopic rod 22, providing power to the rod 22 to tilt and reset the housing 21. The hydraulic cylinder 23 consists of a high-strength cylinder body, a piston, a piston rod, oil inlet and outlet ports, and seals. The piston rod is fixedly connected to the telescopic rod 22 via a connector. Hydraulic oil flowing through the inlet and outlet ports drives the piston rod to extend and retract, thereby controlling the movement of the telescopic rod 22 and achieving precise control of the tilt angle and speed of the housing 21. High-performance seals prevent hydraulic oil leakage, ensuring system stability and durability.

[0039] like Figure 3 The driving device 1 also includes a body 12, and a clamping rod 15 is provided at each of the four corners of the bottom of the body 12. The end of the clamping rod 15 is rotatably connected to the driving wheel assembly 14, and a slide groove 151 is provided at the end of the clamping rod 15, and the chain adjustment assembly 11 is slidably connected to the slide groove 151.

[0040] Specifically, the vehicle body 12 is a rectangular frame structure, approximately 1.5 meters long, 0.8 meters wide, and 0.5 meters high. Made of high-strength aluminum alloy, it ensures lightweight yet possesses excellent strength and corrosion resistance. The vehicle body 12 includes a control system board 121, a battery compartment 122, a range extender 123, a four-wheel drive motor 124, an LCD display 125, and headlights 126. Each component is precisely designed and securely connected to ensure optimal performance and durability.

[0041] Specifically, the control system board 121, located in the front area of ​​the vehicle's top, manages the vehicle's operational logic and signal processing. Connected to various vehicle components via internal wiring, the control system board 121 controls functions such as speed, steering, and power distribution. Its high-performance processor and waterproof design ensure stable operation in harsh environments.

[0042] Specifically, the battery compartment 122 is located in the central area of ​​the vehicle body 12 and is used to store the battery pack that provides power to the vehicle. Made of corrosion-resistant materials, the battery compartment 122 features a secure battery fixture to prevent the battery from moving during vehicle movement. The battery compartment 122 also incorporates a heat dissipation structure to prevent overheating.

[0043] Specifically, the range extender 123 is located at the rear underbody 12 and provides additional battery life. The range extender 123 charges the battery using fuel-generated electricity, making it particularly suitable for long-duration or long-distance operations. A cable connects the range extender 123 to the battery compartment 122 for charging, and the range extender 123 is mounted in a convenient location for maintenance and refueling.

[0044] Specifically, the four-wheel drive motor 124 is mounted in the center of the vehicle body 12 and is the primary power source. The four-wheel drive design provides the vehicle with robust off-road capabilities and stability, making it suitable for use on a variety of complex terrains. The four-wheel drive motor 124 utilizes a highly efficient and energy-efficient design and is directly connected to the battery compartment 122. Its operating status is controlled by the control panel 121.

[0045] Specifically, the liquid crystal display screen 125 is installed at the upper front end of the vehicle body 12, facing the operator, and is used to display information such as the vehicle's operating status, power level, and cruising range. The display screen adopts a high-brightness, low-power design to ensure clear reading even under strong light. The display screen also has a touch function, and the vehicle operating parameters can be adjusted by touch. The headlights 126 are located on both sides of the front of the vehicle body 12 to provide lighting for the vehicle to operate at night or in low-visibility environments. The headlights 126 use high-brightness LED lamp beads with a wide-angle lighting range and long life, which can effectively improve work efficiency and safety.

[0046] like Figure 5-6 The clamping rods 15 are H-shaped. Their specific dimensions depend on the overall design of the transport vehicle, but are typically 0.5 meters long. They are evenly distributed at the four corners of the bottom of the vehicle body 12 to provide balanced support and stability. The clamping rods 15 are connected to the bottom of the vehicle body 12 by welding or bolting.

[0047] Specifically, the clamping rod 15 is provided with a slot 151 at its bottom, connecting the clamping rod 15 to the drive wheel assembly 14 via this slot 151. A mud scraper 153 is mounted above the drive wheel assembly 14. Its primary function is to remove dirt or debris that may adhere to the drive wheel 143 during driving, preventing such debris from entering the drive wheel 143 and damaging the vehicle's drivetrain. Made of high-strength, wear-resistant material, the mud scraper 153 is designed in a serrated or curved shape to conform to the tire surface and maximize mud removal. Furthermore, the mud scraper 153 acts as a mud barrier, reducing contamination of the vehicle body 12 by muddy water.

[0048] Specifically, the toolbox 152 is located above the scraper 153 and is designed as a compact box 21. It features multiple compartments for storing various tools and repair parts. Made of lightweight yet durable materials, the toolbox 152 is sealed on the outside to protect the tools inside from adverse weather conditions. The toolbox 152 is welded to the scraper 153 to prevent it from loosening due to vehicle vibration or bumps. The lid of the toolbox 152 is lockable, enhancing safety and preventing tools from falling due to vibration during driving.

[0049] like Figure 5-6 The drive wheel assembly 14 includes a rotating shaft 141, a sprocket 142, and a drive wheel 143. The rotating shaft 141 is cylindrical with a diameter of approximately 0.05 meters and a length determined by the width of the vehicle body 12. It extends through the entire clamping rod 15. The rotating shaft 141 is made of high-strength alloy steel to withstand the dual pressures of drive and load. The rotating shaft 141 is supported by the chain adjustment assembly 11 and is slidably connected to the clamping rod 15 of the vehicle body 12.

[0050] Specifically, sprocket 142 is a circular gear with a tooth count and diameter designed to meet drive requirements, ensuring perfect meshing with chain 13. Sprocket 142 is mounted on rotating shaft 141 and connected via a keyway or spline, ensuring synchronous rotation of the gear and rotating shaft 141. Drive wheel 143 is circular, approximately 0.4 meters in diameter and 0.1 meters thick, with a deeply treaded tire for enhanced grip. Drive wheel 143 is mounted on rotating shaft 141 via a hub and secured with bolts to ensure a tight connection.

[0051] It is worth noting that the drive wheel assembly 14 also includes curved tire guards 144, which are used to separate crops in front of the vehicle. Four tire guards 144 are mounted on the drive wheel assembly 14. Their curved design closely matches the curve of the tires. Their primary function is to separate crops in front of the vehicle as it moves forward, preventing damage from contact with the tires. During operation, the guards gently push the crops to one side, freeing up space between the tires and the rest of the vehicle, minimizing damage or crushing of the crops.

[0052] like Figure 6 The chain adjustment assembly 11 includes a connecting ring 111, and a drive wheel assembly 14 includes a rotating shaft 141. The connecting ring 111 is sleeved on one end of the rotating shaft 141, and a sprocket 142 is sleeved on the other end. The chain 13 is meshed with the sprocket 142. The chain 13 is a standard roller chain, and its length is adjusted according to the size of the vehicle body 12 to ensure a close fit with the drive wheel assembly 14 and the chain adjustment assembly 11. It is made of high-strength steel to ensure stability and life under high load conditions. The chain 13 meshes with the sprocket 142 on the drive wheel assembly 14, and the tightness of the chain 13 can be adjusted through the adjustment assembly to adapt to different load requirements.

[0053] like Figure 7 The chain adjustment assembly 11 also includes a fixed plate 114, which is fixedly connected to the inner wall of the clamping rod 15. The fixing plate 114 is detachably connected to the adjusting rod 112, and the end of the adjusting rod 112 is connected to a connecting ring 111. The lower part of the fixed plate 114 is connected to an adjusting bolt 113 for changing the axial position of the adjusting rod 112.

[0054] Specifically, the fixing plate 114 is typically a rectangular plate, with a length matching the width of the inner wall of the clamping rod 15 and a thickness of approximately 5-10 mm. The fixing plate 114 is securely connected to the clamping rod 15 by welding or bolting, ensuring that the fixing plate 114 and the clamping rod 15 form a single unit with sufficient load-bearing capacity. The adjustment rod 112 is cylindrical and of an appropriate length to meet the adjustment range requirements of the chain 13. One end of the adjustment rod 112 is pivotally connected to the support plate 32 via a hinged connection, and the other end is connected to a connecting ring 111 to facilitate adjustment of the tightness of the chain 13.

[0055] Specifically, the connecting ring 111 is an annular structure with an inner diameter slightly larger than that of the rotating shaft 141, making it easy to fit onto the rotating shaft 141. The connecting ring 111 is tightly connected to the adjusting rod 112 via bolts or welding, ensuring that it can withstand sufficient force during adjustment without deformation or loosening. The adjusting bolt 113 is a conventional threaded rod with a diameter of typically 10-20 mm. The adjusting bolt 113 is located below the hole in the fixing plate 114 and is connected to the adjusting rod 112. The position of the connecting ring 111 can be adjusted by rotating the bolt.

[0056] Specifically, a slot 151 is defined at the lower portion of the clamping rod 15. The design of slot 151 coordinates with the position of the fixing plate 114 and the adjusting rod 112, allowing the adjusting rod 112 to move up and down within slot 151. Rotating the adjusting bolt 113 creates axial displacement between the adjusting bolt 113 and the fixing plate 114, causing the adjusting rod 112 to move up and down. The movement of the adjusting rod 112 drives the connecting ring 111 within slot 151, effectively changing the position of the connecting ring 111.

[0057] Specifically, a rotating shaft 141 is sleeved onto the connecting ring 111, and a sprocket 142 is rotatably connected to the rotating shaft 141. As the connecting ring 111 moves up and down, the rotating shaft 141 changes height, and the gears adjust their positions accordingly. This design allows the tension of the chain 13 to be adjusted as needed, ensuring optimal operation of the transmission system.

[0058] like Figure 8 The spraying mechanism 3 is installed on the box cover 212 of the loading box 2. The spraying mechanism 3 includes a positioning plate 31 installed on the loading box 2. A support plate 32 is installed at the lower part of the positioning plate. A spraying assembly 33 with an adjustable spraying angle and a drive motor 34 are provided on the support plate 32. The spraying mechanism 3 also includes an electric medicine pump 35. The electric medicine pump 35 includes a controller 351 and a medicine pump 352. The controller 351 electrically controls the medicine pump 352 to provide power for the spraying mechanism 3.

[0059] Specifically, the positioning plate 31 is usually an "H"-shaped plate structure, and its size is customized according to the size of the loading box 2 to ensure that it can be firmly installed on the loading box 2. The positioning plate 31 includes a plate body 311 and fixing bolts 312. Two mounting holes are reserved on the plate body 311, and the fixing bolts 312 are fixed to the end plate of the loading box 2 through the mounting holes.

[0060] Specifically, the fixing plate 114 is a rectangular plate fixed to the lower portion of the retaining plate 31 by bolts or welding, serving as a mounting platform for the spray assembly 33 and the drive motor 34. The spray assembly 33 includes a slide rail 331 disposed on the upper portion of the support plate 32 and a spray pipe 334 rotatably connected to the end of the support plate 32. The free end of the spray pipe 334 is mounted with a connecting rod 333, and the other end of the connecting rod 333 is provided with a slider 332, which slides on the slide rail 331.

[0061] Specifically, the slide rail 331 is made of a high-strength metal, such as stainless steel or aluminum alloy, with excellent corrosion resistance and wear resistance, ensuring long-term use in harsh environments. The length of the slide rail 331 is customized according to the size of the loading box 2, usually within a meter range, with a moderate width and height to facilitate the smooth installation of the slider 332. The design of the slide rail 331 should ensure that the slider 332 can slide smoothly on it without noticeable obstruction or shaking. The slide rail 331 is fixed to the upper portion of the fixed plate 114 by welding or bolts. During installation, it is necessary to ensure that the slide rail 331 is parallel to the fixed plate 114 to ensure the movement accuracy of the spray pipe 334.

[0062] Specifically, the spray pipe 334 is made of a durable metal material, typically stainless steel, which is corrosion-resistant and pressure-resistant to withstand corrosion from various chemicals. The length of the spray pipe 334 depends on the specific operating range and is typically 0.5-1 meter, with a diameter of approximately 2-4 centimeters to ensure sufficient flow and spraying area. The end of the spray pipe 334 is designed with multiple nozzles, the aperture of which can be adjusted to achieve different spraying effects. The spray pipe 334 is connected to the end of the fixed plate 114 via a hinge and can rotate within a certain angle range to accommodate different spraying angle requirements.

[0063] Specifically, connecting rod 333 is typically made of high-strength steel, has a circular or square cross-section, and is approximately 20-30 cm long. One end of connecting rod 333 is fixed to the free end of spray pipe 334, and the other end is connected to slider 332. The connection between connecting rod 333 and spray pipe 334 utilizes a detachable structure, such as a threaded connection or a quick connector, to facilitate installation and maintenance. Furthermore, the hinged connection between connecting rod 333 and slider 332 allows for more flexible movement of spray pipe 334.

[0064] Specifically, the slider 332 is made of a wear-resistant material, such as high-strength plastic or alloy steel, to ensure that it is not easily worn out during long-term sliding on the slide rail 331. A ball bearing or a slider 332 seat is provided inside the slider 332 to ensure smooth movement on the slide rail 331. The shape of the slider 332 matches the slide rail 331 to prevent derailment. The slider 332 drives the spray pipe 334 to move on the slide rail 331 through the connecting rod 333 to adjust the spraying area. The drive motor 34 precisely controls the position and speed of the slider 332 through the control system to meet different operation requirements.

[0065] like Figure 4 The tube reel device 4 includes a tube reel shaft 41 rotatably connected to one side of the vehicle body 12 and a tube reel motor 43 arranged inside the vehicle body 12. Circular limit plates 42 are provided on both sides of the tube reel shaft 41. A tube reel chain 44 is connected to the output shaft of the tube reel motor 43. The other end of the tube reel chain 4 is connected to the end of the tube reel shaft 41.

[0066] The hose reel 4 significantly improves the efficiency and convenience of farmland irrigation. The hose reel shaft 41 is equipped with a self-sprinkling hose over 100 meters long, which can be automatically reeled up at the edge of the field. During use, the hose is laid along the farmland. After the irrigation task is completed, simply start the hose reel motor 43, and the hose will automatically and orderly reel up, eliminating the need for manual operation in the field. This design not only effectively reduces the risk of farmers trampling on crops during the hose reeling process, but also significantly saves manpower and improves the efficiency and comfort of irrigation operations.

[0067] Specifically, the reel shaft 41 is a cylindrical shaft. Its length is designed to match the width of the vehicle body 12, typically 0.5 meters, and its diameter is approximately 20-50 mm, providing sufficient strength and stability. The reel shaft 41 is mounted on the side of the vehicle body 12 via a rotating bracket 45, allowing it to rotate freely. The rotating bracket 45 is sealed to prevent the ingress of dust and debris, ensuring smooth operation of the shaft.

[0068] Specifically, the reel motor 43 is a standard industrial motor, typically with a power range of 500 watts to 1 kilowatt. It is securely fastened to the vehicle body 12 using bolts or a dedicated mounting bracket. The motor is connected to the reel shaft 41 via a coupling. The coupling utilizes either an elastic or rigid structure to ensure the motor's rotational force is effectively transmitted to the reel shaft 41 while also absorbing potential vibration and shock.

[0069] Specifically, the output shaft of the reel motor 43 is connected to a reel sprocket, which is then connected to the reel sprocket on the reel shaft 41 via a reel chain 44. The reel chain 44 is made of wear-resistant rubber, offering excellent transmission efficiency and durability. The ends of the reel chain 44 are respectively connected to the reel sprocket on the output shaft of the reel motor 43 and the reel shaft 41. Friction transmits the motor's rotational power, enabling the reel shaft 41 to rotate synchronously with the motor.

[0070] The workflow of this embodiment is:

[0071] First, the multifunctional remote-controlled transport vehicle is activated through the control system panel 121, and the vehicle speed and spraying parameters are adjusted according to the operational requirements. The chain adjustment assembly 11 is then used to adjust the tightness of the chain 13 to ensure smooth operation on various terrains. Next, the drive unit 1 begins operation. As the vehicle advances, the spray mechanism 3 mounted on the loading box 2 begins operating. The drive motor 34 drives the spray assembly 33 along the slide rail 331, achieving precise spraying of the farmland. Simultaneously, the hose reel 4 deploys or retracts the hose as needed, providing a continuous source of water or spray solution.
