Description

Technical Field

[0001] This invention relates to the field of multifunctional machinery, and in particular to an intelligent multifunctional integrated machine. Background Technology

[0002] In the fields of agricultural engineering and small construction machinery, integrated excavator-loaders, which combine excavation, loading, and transportation functions, are widely used in construction sites with limited space and multiple operational procedures due to their multi-functionality. Especially in hilly and mountainous areas, where large single-function construction machinery is difficult to access or operate due to limited land, undulating terrain, and rugged roads, there is an urgent market demand for a small, integrated work equipment that is flexible, highly functional, and adaptable to complex terrain. Existing integrated excavator-loaders typically consist of a power system, a walking mechanism, working devices (such as the excavator arm and loading bucket), and a control system, capable of performing basic excavation and material handling operations.

[0003] However, existing excavator-loader integrated machines still have many shortcomings in practical applications, including: First, the power system design is unreasonable. They typically use a single power source or a simple dual-pump split, sharing hydraulic power for walking, excavation, and attachment operations. This leads to severe power interference and low distribution efficiency when multiple actions are performed simultaneously, failing to meet the combined working conditions of excavation, loading, and driving other agricultural implements (such as rotary tillers and seeders). Second, the control system has low intelligence. It mostly uses traditional mechanical levers or pilot hydraulic controls, which are cumbersome and inaccurate. Furthermore, operators must be in the cab, compromising safety in dangerous or confined environments such as hilly areas. While some remote control solutions exist, they only enable remote control of walking or a single action, failing to achieve dual-mode (local + remote) control for all actions and functions. Third, the hydraulic system's cooling capacity is insufficient. During prolonged continuous operation, the hydraulic oil temperature rises excessively, leading to decreased system stability and shortened seal life. Existing technologies only use a simple single-stage radiator to cool the return oil, neglecting the impact of heat storage in the hydraulic oil tank on the system. Fourth, the walking and steering mechanisms have poor adaptability. Traditional differential steering or articulated steering requires a large turning radius, making it difficult to turn around flexibly in narrow plots, terraced fields, or orchards in hilly and mountainous areas, severely limiting operational efficiency and scenario applicability. Fifth, the functional integration is limited. The backend usually lacks standardized interfaces, making it difficult to quickly replace various agricultural implements, resulting in farmers still needing to purchase multiple devices, leading to high investment costs.

[0004] Therefore, there is an urgent need in this field to solve the technical problems of existing excavator-loader integrated machines, such as unreasonable power distribution, low level of intelligent operation, insufficient hydraulic cooling, poor steering flexibility, and limited functional integration, in order to provide a solution that can truly adapt to the complex working environment of hilly and mountainous areas and achieve efficient, safe, and multifunctional integrated operation. Summary of the Invention

[0010] Preferably, the remote controller is wirelessly connected to the PLC controller, and is used to remotely realize all the actions of the machine in dangerous operation scenarios in hilly and mountainous areas.

[0011] Preferably, the hydraulic two-stage cooling system includes a hydraulic oil tank and a radiator. The radiator is integrated with the hydraulic oil tank and is used to cool the circulating hydraulic oil. At the same time, the radiator is used to provide contact cooling for the body of the hydraulic oil tank.

[0012] Preferably, the in-situ tank turning mechanism is electrically connected to the PLC controller, and the PLC controller controls the walking motors on both sides to rotate forward and backward synchronously, thereby realizing the zero-radius in-situ turning of the tank.

[0022] The purpose of this invention is to provide an intelligent multi-functional all-in-one machine to solve the problems existing in the prior art.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: Please see Figures 1 to 3 This invention provides an intelligent multi-functional integrated machine, including a body 1. The body 1 is a self-propelled structure, preferably with a tracked walking mechanism to better adapt to the soft, undulating terrain of hilly and mountainous areas. A diesel engine 2 is installed on the body 1 as the sole power source. A front-end digging device 3 is integrated at the front of the body 1 for digging operations; a standardized rear three-point suspension 4 is installed at the rear of the body 1 for detachably connecting various suspended agricultural implements such as planters, mulching machines, and harvesters, thus achieving multi-functionality. To solve problems such as power interference, inconvenient operation, hydraulic temperature rise, and steering difficulties in existing technologies, this invention focuses on designing a multi-path independent power distribution system, an electro-hydraulic dual control system, a two-stage hydraulic cooling system, and a tank-turning mechanism for on-the-spot maneuvers.

[0025] Please see Figures 1 to 3The aforementioned multi-path independent power distribution system is the core solution to the power interference problem. The power output of diesel engine 2 is precisely divided into three independent paths. The first path is used for travel drive: diesel engine 2 is connected to travel hydraulic pump 6 via travel hydraulic pump transmission belt 5. Travel hydraulic pump 6 drives travel motor 7, and travel motor 7 drives the tracked travel mechanism of machine body 1, thereby realizing independent control of the forward, backward, and turning movements of machine body 1. The second path is used for operation execution: diesel engine 2 drives operation hydraulic pump 8, which is connected to multiple sets of differential cylinders, specifically including first differential cylinder 9, second differential cylinder 10, and third differential cylinder 11, as well as worm gear reducer motor 12. Among them, first differential cylinder 9, second differential cylinder 10, and third differential cylinder 11 work together to control the digging, lifting, and tilting composite actions of the front-end digging device 3, while worm gear reducer motor 12 is used to control the rotation of the entire upper part of machine body 1. Meanwhile, the hydraulic pump 8 is also connected to an independent hydraulic cylinder (not shown) to control the lifting and lowering of the rear three-point suspension 4. The third path is used for external power output: the diesel engine 2 is connected to a parallel shaft reducer 14 via a reducer drive belt 13. The output end of the reducer 14 is connected to an electromagnetic clutch 15, which in turn is connected to a power take-off shaft (PTO) 16. By controlling the on / off state of the electromagnetic clutch 15, the start and stop of the power take-off shaft 16 can be controlled independently and precisely, thus providing independent and stable rotational power to the external implements (such as planters, mulching machines, harvesters, etc.) mounted on the rear three-point suspension 4. These three power paths are physically independent and hydraulically independent, with power output proportionally distributed from the flywheel end of the diesel engine 2, thereby fundamentally solving the problems of power interference and low distribution efficiency when multiple actions are performed simultaneously.

[0026] Please continue reading. Figures 1 to 3To achieve high-precision and high-safety control, this invention integrates a fully electro-hydraulic dual control system. This system uses a PLC controller 17 as its core, paired with a high-response hydraulic valve assembly 18 as the actuator. Four dedicated electric control handles are integrated on the control panel of the machine body 1, each undertaking a different control function. The first electric control handle 19 is electrically connected to and controls the extension and retraction of the first differential cylinder 9, the second differential cylinder 10, and the hydraulic cylinder controlling the lifting and lowering of the rear three-point suspension 4. The second electric control handle 20 is electrically connected to and controls the engagement and disengagement of the third differential cylinder 11, the worm gear reducer motor 12, and the electromagnetic clutch 15 in the third path. The third electric control handle 21 is electrically connected to and controls the machine body 1's walking direction, high / low speed switching, and activation of the tank turn function. The fourth electric control handle 22 directly controls the forward and backward movement of the machine body 1. The control signals generated by these four electric control handles are transmitted to the PLC controller 17, processed, and then precisely executed by the hydraulic valve assembly 18. Meanwhile, the system is also equipped with an independent remote control, which maintains a real-time connection with the PLC controller 17 via a wireless communication protocol. The remote control has control elements that correspond one-to-one with the functions of the four electric control handles, allowing operators to remotely control all machine actions, including digging, hoisting, rotation, walking, turning, U-turns, and power output, from a safe distance away from the machine body 1. This dual-mode design, encompassing both local handle operation and remote control operation, ensures convenience in routine operations while completely resolving personnel safety issues when working in dangerous or confined environments such as hilly slopes, landslide areas, etc.

[0027] Please see Figure 3 To address the issue of hydraulic system temperature rise caused by prolonged continuous operation, this invention designs a unique two-stage hydraulic cooling system. This system includes a hydraulic oil tank 24 and an independent radiator 23. Unlike traditional designs where the radiator is only connected to the return oil line, in this invention, the radiator 23 is integrated with the hydraulic oil tank 24; specifically, the radiator 23 is tightly attached to and fixed to one side or the bottom of the hydraulic oil tank 24. During hydraulic system operation, the high-temperature return oil first flows through the internal tube bundle of the radiator 23 for the first stage of cooling—active heat dissipation of the circulating oil. Simultaneously, the hydraulic oil tank 24 absorbs and accumulates a large amount of heat after prolonged operation. Due to the cooling fan of the radiator 23 or natural convection, its body temperature is typically lower than that of the hydraulic oil tank 24. Therefore, while cooling the circulating oil, the radiator 23 acts as a highly efficient heat absorber, providing a second-stage passive cooling to the hydraulic oil tank 24 through contact heat conduction. This achieves simultaneous and efficient cooling of the hydraulic oil and the hydraulic oil tank, effectively controlling the overall temperature rise of the system and significantly improving the stability of the hydraulic system under continuous heavy load conditions and the service life of the seals.

[0028] To address the challenge of turning in confined spaces in hilly and mountainous terrain, this invention integrates a tank-turning mechanism precisely controlled by a PLC controller 17. Specifically, the core of this mechanism lies in the control logic of the PLC controller 17 over the two independent travel motors 7. When the operator triggers a "tank turn" command via the third electric control handle 21 or a remote control, the PLC controller 17 receives the command and immediately outputs a forward rotation command to the left travel motor 7 and a reverse rotation command to the right travel motor 7. The two travel motors 7 then drive their respective tracks to rotate synchronously at the same speed but in opposite directions. Under this driving torque, the machine body 1 achieves a zero-radius turn in place with its geometric center as the center. After the turn is complete, the PLC controller 17 simultaneously stops the reverse commands of the two motors or resumes the same-direction commands, allowing the machine body 1 to continue moving forward or backward. This process is entirely automated by the PLC controller 17, eliminating the need for complex throttle and brake coordination by the operator, greatly improving operational flexibility and efficiency in confined spaces such as terraced fields and orchards.

[0029] Furthermore, as a preferred option, the front-end digging device 3 has a maximum digging depth of 60cm and a standard digging width of 1 meter, which can be flexibly adjusted by changing the bucket or adjusting the bucket side plates. The rear three-point suspension 4 is a standardized suspension system that conforms to national or industry standards, and can be quickly connected with most agricultural implements such as planting machines, mulching machines, and harvesters on the market. During operation, the operator can selectively activate various functional modules through the control system according to the needs of the operation: when digging is required, the digging device 3 is controlled by the second electric control handle 20; when transporting or performing farmland operations, the lifting and lowering of the rear suspension and the rotation of the external implements are controlled by the first electric control handle 19 and the electromagnetic clutch 15; when turning around in narrow plots, the tank turn function can be activated with one button. All actions can be executed independently or in combination without interference. Thus, the intelligent multi-functional all-in-one machine provided by this invention, through the synergistic effect of its original power distribution, electro-hydraulic control, dual-mode operation, two-stage cooling and on-the-spot turning structure, fully realizes its design goals of high efficiency, safety, multi-functionality and high adaptability.
