Description

Technical Field

[0001] This utility model relates to a ride-on work machine, specifically an agricultural and garden ride-on work machine. Background Technology

[0002] In the pursuit of agricultural modernization, efficient and reliable agricultural machinery has become an indispensable aid. Compared to walk-behind agricultural machinery, ride-on agricultural machinery with seats allows the operator to work while seated, greatly reducing labor intensity and fatigue, and making operation easier, more flexible, and improving accuracy and efficiency. Ride-on agricultural machinery typically consists of several parts, including an energy supply system, a transmission system, and working components. The energy supply mainly comes in two forms: an internal combustion engine and an electric motor. The transmission system converts energy into the machine's propulsion. The working components are the core components of the machine, directly participating in the operation process. Depending on the specific operational needs, the forms of working components vary, including cutters, pick-ups, plows, and planting devices.

[0003] For example, Chinese patent document CN203793461U discloses a multi-functional work machine, including a frame, a power output system, an operating platform, a tracked walking mechanism, a transport truck bed, and the work machinery. The power output system is located on the right side of the front of the frame, the operating platform is located on the left side of the front of the frame, the tracked walking mechanism is located on the left and right sides of the frame, and the transport truck bed is located above the tracked walking mechanism at the rear of the frame. A three-point hydraulic suspension device is installed at the rear of the frame, and the work machinery is connected to the frame through the three-point hydraulic suspension device. The power output system is connected to the work machinery through a universal joint drive shaft. With this structure, it has advantages such as simple and compact structure, flexible and convenient operation, safe and reliable use, and versatility, meeting the needs of crop transportation, farmland conservation tillage, and agricultural machinery drive and traction.

[0004] For example, US Patent Document US6659209B2 discloses a tractor including a pair of frames extending in a longitudinal direction, and a gearbox extending and supported between the pairs of frames. An engine is located at the front of the tractor body, and a gearbox is mounted at the rear of the tractor body, both mounted between a pair of left and right body frames. The HST is rigidly connected to the front of the gearbox housing and connected to the engine via a driveshaft. A front-wheel drive shaft and a center PTO shaft extend forward from the gearbox, respectively for driving the front wheels and the lawnmower. Additionally, a rear PTO shaft extends rearward from the gearbox for driving the rear working device. A hydraulic cylinder integrally formed with its upper surface on the gearbox housing is used to raise and lower the rear working device and supports the axle of the lifting arm. The body frame is constructed of plates with vertically extending portions, and the gearbox is bolted to its inner surface.

[0005] In the aforementioned prior art, since the power unit and transmission unit are respectively located at the front and rear of the tractor body, this transmission method has the problem of excessively long power transmission path and complex power transmission structure, resulting in low power output efficiency. Utility Model Content

[0006] To address the technical problem of low transmission efficiency in existing work machines, this utility model provides a ride-on work machine, including a vehicle frame. The vehicle frame is equipped with an operating unit, a power unit, a transmission unit, and a work tool interface. The power unit is located on the side of the transmission unit facing the operating unit. The side of the power unit facing the transmission unit has a power connection port, through which the power unit is directly connected to the transmission unit.

[0007] In existing technologies, the complex power transmission path between the power unit and the transmission unit leads to significant power loss during output, resulting in low transmission efficiency. In this solution, however, the power unit and transmission unit are directly connected, with the power connection port of the power unit facing the transmission unit. This shortens the distance between the two units and simplifies the power transmission path, effectively improving transmission efficiency. Furthermore, the direct connection between the power unit and transmission unit reduces the overall size of the machine, enhancing its applicability in confined space environments.

[0008] Preferably, the power unit is positioned close to the transmission unit. In this design, positioning the power unit close to the transmission unit shortens the power transmission path, thus ensuring efficient power output.

[0009] Preferably, the power unit is directly connected to the transmission unit via a transmission component. In this solution, the transmission component is a connecting sleeve that connects the power unit and the transmission unit. It has the advantages of low cost and simple structure, and can avoid the problems of wasted space caused by using universal joints and other transmission solutions on the market.

[0010] Preferably, the transmission unit is further provided with a PTO shaft for connecting the working tool on the side opposite to the operating unit. In this design, the transmission path between the transmission unit and the PTO shaft is shortened, thereby improving the power transmission efficiency.

[0011] Preferably, the vehicle frame is connected to a rear-mounted walking mechanism or a drive wheel, and a walking drive shaft is located below the transmission unit, connected to the rear-mounted walking mechanism or the drive wheel. This design allows the work machine to have either four-wheel drive or two-wheel drive capability, allowing users to choose according to their actual needs and expanding the market for the work machine.

[0012] Preferably, the travel drive shaft is connected to the rear travel mechanism, the vehicle frame is connected to the front travel mechanism, and the travel drive shaft is also connected to the front travel mechanism via a transmission connection. This solution enables the work machine to achieve four-wheel drive mode and has a simple structure.

[0013] Preferably, the drive wheel is fitted with a track, and the drive shaft is connected to the drive wheel via a transmission. This design can meet the walking requirements of the machine in some complex environments, thus enabling the machine to adapt to more working scenarios.

[0014] Preferably, a riding unit is also provided on the vehicle frame, located above or in front of the power unit. In this design, placing the riding unit above or in front of the power unit can prevent a large shift in the center of gravity of the work machine when the operator sits on it and works on slopes, thus avoiding problems such as poor safety and insufficient maneuverability caused by the center of gravity shift.

[0015] Preferably, the power unit is an internal combustion engine. In this solution, using an internal combustion engine as the power unit of the work machine has advantages such as good economy and high working efficiency, thereby ensuring the mobility of the work machine.

[0016] Preferably, a fuel tank is also provided on the vehicle frame, located on one side of the power unit input end. In this design, placing the fuel tank on one side of the power unit input end can prevent the fuel tank from overheating and can improve the utilization of space under the operator's legs while facilitating refueling.

[0017] Preferably, the input end of the power unit is further provided with a cooling unit that cools the power unit and directs the cooling air toward the output end of the power unit. This solution can cool the power unit and the transmission unit, and also prevent the heat generated by the power unit during operation from accumulating, thereby avoiding an unpleasant operating experience for the operator.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the distance between the power unit and the transmission unit is effectively shortened, and the power transmission path is simplified, which means that the transmission path of the power output by the power unit is shortened, thereby effectively improving the transmission efficiency.

[0020] 2. This utility model can shorten the power transmission path of the power unit, thereby ensuring efficient power output, while effectively reducing the overall size of the machine and improving its applicability in confined space operation scenarios.

[0021] 3. This utility model enables the work machine to have four-wheel drive or two-wheel drive modes, which users can choose according to their actual needs. This can expand the sales market for the work machine and meet the walking needs of the work machine in some complex environments, thereby enabling the work machine to adapt to more work scenarios.

[0022] 4. This utility model can prevent the center of gravity of the machine from shifting significantly after the operator sits on it, thus avoiding problems such as poor safety and insufficient operability caused by the deviation of the center of gravity.

[0023] 5. This utility model can prevent the fuel tank from overheating and improve the space utilization under the operator's legs while facilitating refueling; it can also prevent the heat generated by the power unit from accumulating during operation, thus avoiding an unpleasant operating experience for the operator.

[0027] The following detailed description illustrates the specific implementation method:

[0028] 1. Definition

[0029] Direct-drive transmission: This refers to a mechanical transmission method that transmits power and torque by directly connecting two or more rotating parts. Compared with multi-stage transmissions and reducer transmissions, direct-drive transmissions have the following characteristics: 1. Simplicity: Direct-drive transmissions have no intermediate transmission devices, resulting in a simple structure and convenient maintenance; 2. High efficiency: Because there are no transmission devices to cause power loss, direct-drive transmissions are relatively efficient; 3. Energy saving: The high efficiency of direct-drive transmissions reduces energy loss within the system, thus saving energy.

[0030] PTO shaft: Power take-off shaft, used to transmit part of the engine's power to equipment or machinery that requires power.

[0031] The running gear, also known as the "travel mechanism," is part of the chassis of a car or tractor, generally including the frame, front axle, rear axle, suspension system, and wheels. The part of the running gear that directly contacts the road surface is the wheels, called a wheeled running gear. In addition, there are several other types, such as half-track running gear, wheel-track running gear, and tracked running gear. Half-track running gear has wheels or skids mounted on the front axle and tracks mounted on the rear axle, mainly used for traveling in snow or swampy areas. Wheel-track running gear has interchangeable wheels and tracks. The running gear of a tracked tractor consists of two parts: the suspension system and the tracked walkway.

[0032] 2. The reference numerals in the accompanying drawings of the instruction manual include: operating unit 1, front wheel 2, fuel tank 3, riding unit 4, vehicle frame 5, cooling unit 6, power unit 7, output shaft 8, transmission unit 9, PTO shaft 10, connecting sleeve 11, and track 12.

[0033] Note that in this embodiment, the left end of the vehicle frame 5 is considered the forward direction, and the right end is considered the rearward direction.

[0034] Example 1

[0035] The basics are as follows: Figure 1 and Figure 2 As shown: A ride-on work machine includes a vehicle frame 5, on which an operating unit 1, a front traveling mechanism, a fuel tank 3, a riding unit 4, a power unit 7, a transmission unit 9 and a rear traveling mechanism are provided along the front-to-back direction.

[0036] The operating unit 1 is located in front of the vehicle frame 5. The operating unit 1 includes a steering wheel, accelerator, brake, clutch, etc. The operator controls the operating unit 1 to start, drive, steer and stop the work machine.

[0037] The forward travel unit includes forward travel wheels 2 and a forward travel drive axle, enabling the machine to steer.

[0038] The seating unit 4, providing a seating position for the operator, is located in the middle of the vehicle frame 5, above or to the left of the power unit 7; if the seating unit 4 is located to the left of the power unit 7, such as... Figure 1 As shown; the passenger unit 4 is located above the power unit 7, as... Figure 2 As shown.

[0039] The fuel tank 3 provides fuel to the power unit 7. It is located below the passenger unit 4 and is positioned at the input end of the power unit 7 and in front of the power unit 7.

[0040] The power unit 7 is located in the middle of the body frame 5 along its length. The power unit 7 is an internal combustion engine that directly converts the heat energy released from the combustion of fuel inside the machine into power. The input end of the power unit 7 is also equipped with a cooling unit 6, which cools the power unit 7 and directs cooling air towards its output end. The cooling unit 6 uses a cooling fan. The output shaft 8 of the power unit 7 is positioned towards the transmission unit 9, meaning the output shaft 8 of the power unit 7 is positioned rearward.

[0041] The transmission unit 9 is fixed to the rear of the vehicle frame 5. The transmission unit 9 is directly connected to the power unit 7 via a transmission component. The transmission unit 9 includes gears, shafts, bearings, and a housing, and is used to convert the power of the power unit 7 into the force and speed required to drive the work machine. In this embodiment, the transmission component is the connecting sleeve 11 that connects the power unit 7 and the transmission unit 9.

[0042] The vehicle frame 5 is also provided with a working tool interface, which is located at the rear or bottom of the vehicle frame 5. In this embodiment, the working tool interface is located at the rear of the transmission unit 9 on the vehicle frame 5.

[0043] The transmission unit 9 is also provided with a PTO shaft 10 for connecting the working tool on the side opposite to the operation unit 1.

[0044] The vehicle frame 5 connects to the rear travel mechanism and the drive wheel. A travel drive shaft is located below the transmission unit 9, and this shaft connects to either the rear travel mechanism or the drive wheel. This configuration allows users to choose between purchasing a four-wheel drive or two-wheel drive work machine.

[0045] In this embodiment, the walking drive shaft is connected to the rear walking mechanism, the vehicle frame 5 is connected to the front walking mechanism, and the walking drive shaft is also connected to the front walking mechanism in a transmission manner to realize the four-wheel drive state of the work machine.

[0046] The specific implementation process is as follows: During use, the operator in the riding unit 4 uses the operating unit 1 to control the walking and steering of the work machine. When walking, the fuel tank 3 supplies fuel to the power unit 7. After the fuel is burned in the power unit 7, it outputs power, which is transmitted to the walking drive shaft via the transmission unit 9 directly connected to the power unit 7. Then, it drives the rear walking mechanism to move, and finally drives the work machine to walk.

[0047] In this embodiment, since the power unit 7 and the transmission unit 9 are connected by a direct drive, and the power unit 7 is located close to the transmission unit 9 with its power connection port facing the transmission unit 9, the distance between the power unit 7 and the transmission unit 9 is shortened. This means that the power transmission path of the power unit 7 is shortened and the power transmission path is simplified, thereby effectively improving transmission efficiency. The riding unit 4 is also located in the middle of the vehicle frame 5, which prevents the center of gravity of the work machine from shifting after personnel ride on it, and also avoids problems such as poor safety and insufficient maneuverability caused by a shift in the center of gravity.

[0048] Example 2

[0049] like Figure 3 As shown in this embodiment, the vehicle frame 5 is connected to the drive drive wheel, the walking drive shaft is connected to the drive drive wheel, and the drive drive wheel is fitted with a walking track 12, which enables the work machine to adapt to complex terrains such as mud and gravel, and improve agricultural production efficiency.
