The present invention relates to a multi-functional agricultural machine power vehicle, and more specifically, in the driving power transmission method of the multi-functional agricultural machine power vehicle, the engine and the hydrostatic transmission (HST) are directly connected by a flange coupling method, rather than a conventional belt driving method. It solves the problem of unloading of engine and HST bearings and breakage caused by conventional belt wear, and minimizes the power loss by adopting rear wheel drive system, and changes the driving part to the caterpillar type used in the small excavator. The present invention relates to a multi-functional agricultural machine power vehicle that maintains safety in operation by eliminating the problems caused by mounting weight and at the same time by changing the lower roller type from long gear to straight to prevent deviation from the track.

As you know, when you run an orchard or farm, there are a number of tasks, such as composting, plowing, controlling, harvesting crops and loading harvested crops on vehicles. Is performed.

In addition, orchards are often formed on sloping terrain, and it is obvious that transporting crops or loading them on vehicles is more difficult than flat land. Moreover, many of these inclined terrains are inaccessible to vehicles, so the work of harvesting and transporting crops is performed by hand.

By the way, the above-mentioned things are very hard work, so people are reluctant to do these things, and the labor cost of people who do such work is very expensive, so there is a limit to the use of manpower, therefore, the price competitiveness of crops is increased. It has the problem of disappearing.

Moreover, there is often a significant disruption to crop production due to the inability to adequately provide the manpower to do these hard work.

This allows easy access to sloped terrain, facilitates the transport of heavy crops and the loading of vehicles, and the need for a multifunctional agricultural machine powered vehicle capable of carrying functions as well as passenger control, lift and dump. It has emerged.

In other words, loading trucks, passenger control machines, compost spreaders, mowers, and high-end trucks are essential farm machinery used in orchards and farms. There are many difficulties such as economic burden, maintenance and follow-up management by model, and attachment and traction models are not convenient due to unsuitable working conditions in a certain space. By constructing the loading truck by assembling and mounting the assembly parts of passenger type control devices (aka SS (Speed Sprayer), compost spreader, mower, and expensive work cars according to the user's model selection) Drive shaft, hydraulic cylinder and drive motor deliver power to the rotating shaft and operating shaft A multifunctional agricultural machine power vehicle that uses several agricultural machines in one loading truck has been researched and developed.

However, the conventional multi-function agricultural machine power vehicle has a method of increasing the length of the trackless tracks without changing the design according to the increase in load, causing the lower deformation and departure of the rubber track when turning with a weak structure in strength. Had

As such, by using only the length of the running track in existing agricultural machinery products, there is a problem that the track is cut off without exceeding the tension according to the weight when climbing more than 15 °, and conventionally, the number of tracks of the driving sprocket is 7 The tracks were peeled off due to the slim phenomenon of the sprocket.

In addition, in the driving power transmission method, the engine and the HST are arranged in parallel and driven by the belt driving method. As a result, excessive tension is used to prevent the belt from slimming. Therefore, the engine output bearing and the mission HST input shaft are There is a problem that excessive bearing load occurs in the bearing and a broken phenomenon due to belt wear occurs.

And, Figure 6 and Figure 7 is a use example showing a state that the loading box is used to be assembled and mounted on a multi-function agricultural machine power vehicle according to the present invention.

As shown in the drawings, the multi-function agricultural machine power vehicle according to the present invention, by selecting and assembling in a suitable work machine form according to the work to be performed in the farmhouse, a variety of vehicles, such as a control unit (SS), lift, dump, etc. As a power vehicle adopting the rear wheel driving method to be used as a work type, it has a configuration that can secure enough power to be utilized as a multifunctional farming machine as described above, and has a trackless way to have a suitable driving condition for Korean terrain. The traveling part 30 is provided.

That is, the multi-function agricultural machine power vehicle according to the present invention is directly connected to the engine unit 10 and the engine unit 10 capable of driving the traveling sprocket 32 constituting the traveling unit 30 of the crawler system. Hydraulic transmission system (HST) 20 which can facilitate gear shifting, a transmission unit 40 connected to the hydraulic transmission unit 20, and a universal joint 41 to the transmission unit 40. A driving unit 30 that receives power from the rear wheel shaft 51 connected to the driving unit 30, and a reduction unit 50 connected to the universal joint 41 on the rear wheel shaft 51 to perform power compensation; The main frame 60 supports and fixes the respective parts to form a vehicle body, and a loading part 70 provided on the rear end of the main frame 60.

Here, the engine unit 10 according to the present invention replaces the engine of 23 horsepower, which is conventionally applied to agricultural machinery products having a 1000kg loading capacity, by replacing the engine with 36 horsepower, the power shortage due to the increase in the installed weight through the engine output improvement To solve the problem.

Then, on one side of the main frame 60 in which the engine unit 10 is installed, the driver's seat 80 which can be seated by the user, a lever 81 for controlling the above components, and a controller (not shown) are installed.

In particular, according to the present invention, in the driving power transmission method through the engine unit 10 to directly connect the engine unit 10 and the hydraulic motor (HST; 20) by a flange coupling method instead of the existing belt driving method It is taking structure.

Through such a structure, the problem of the unloading of the engine and the HST bearing 21 appearing in the conventional belt driving method is solved, and the problem of breaking due to the conventional belt wear is fundamentally solved.

The hydraulic transmission device (HST) 20 is a transmission device for transmitting mechanical rotational power by configuring a hydraulic pump and a hydraulic motor (not shown) in an open or closed circuit.

The hydraulic transmission apparatus (HST) 20 has the characteristic of continuously changing the speed ratio and torque ratio by changing the displacement of the hydraulic pump or hydraulic motor (not shown), which is small and light, and high rigidity. It is excellent controllability is applied to a variety of construction machinery, agricultural machinery, industrial vehicles, etc., in the present invention, the hydraulic transmission device 20 between the engine unit 10 and the transmission 40, the engine unit ( It is only directly connected to 10), and the configuration and operation of the hydraulic power transmission apparatus 20 itself is very commonly used, so the detailed and detailed description thereof will be omitted.

However, since the hydraulic transmission device (HST; 20) receiving the power of the engine unit 10 is an apparatus for continuously changing the hydraulic pressure, a cooling device for minimizing the power loss due to the oil temperature rise of the hydraulic oil is essential, but conventionally In the case of the agricultural machine disclosed in the present invention, there was a problem in that the lack of the capacity of the cooling system caused a different oil temperature rise and a steering failure due to a long operation.

In order to improve this, the present invention adopts a cooling fan and a large-capacity cooling condenser (not shown) by its own motor (not shown), thereby ensuring a smooth operation of the oil temperature and a smooth operation of the hydraulic motor (HST) 20 due to long time operation. The hydraulic oil cooling system is complemented to improve turning capability.

The driving unit 30 is configured in a crawler type crawler type to be able to proceed in any terrain conditions, for example, inclined or protruding terrain, or muddy or wet ground.

That is, the driving unit 30 is a sprocket 32 for transmitting power by engaging the rubber track 31, and an idler 33 installed in front to freely rotate and support the rubber track 31; , The lower roller (Track Roller) 34 is installed between the sprocket 32 and the idler 33 and freely rotates and distributes the weight of the equipment evenly to the ground, and the rubber track 31 so that the upper side of the rubber track 31 does not sag. It consists of an upper roller (Carrier Roller) 35 for supporting the weight of 31.

Here, the driving unit 30 of the present invention has the same or similar configuration as the running unit of a conventional tracked vehicle, but in the present design replaces the crawler employed in conventional agricultural machinery as a track being used in a small excavator By applying the change to solve the problems caused by the mounting weight and at the same time the lower roller 34 type is changed from the long form to the straight form to prevent the departure of the track to maintain safety in operation.

For example, in the specification of the rubber track 31 constituting the endless track of the running portion 30, the same loading instead of the rubber track of width 230 mm and pitch 72 mm, which is conventionally applied to agricultural machinery having a 1000 kg loading capacity. In the agricultural machine power vehicle according to a preferred embodiment of the present invention having a capacity to change the specifications of the rubber track to 300mm width, 54mm pitch to compensate for the disadvantages of the conventional products.

In particular, according to the present invention, as shown in the drawings, by adopting the number of teeth of the sprocket 32 constituting the running portion 30 to a large sprocket having 22 formed, 13 teeth of the sprocket 32 at the time of running rubber By always engaging the track 31, it is possible to realize a reliable driving force without the slim phenomenon of the rubber track 31 and the sprocket 32, and to suppress the track peeling phenomenon.

In addition, as shown in the real picture of Figure 5, by changing the pattern pattern formed on the outer surface of the rubber track 31 to a pattern pattern with a gentle inclination to minimize the ground shredding phenomenon when turning.

That is, in the crawler type traveling part used in conventional farming machines, the number of sprockets is usually 7, and the maximum number of teeth is engaged with the rubber track during driving. This problem is solved by changing the sprocket 32 into a large sprocket having 22 teeth.

In addition, since the sprocket 32 of the driving unit 30 is configured to have a large size as described above, power compensation is required due to the large sprocket driving. For this purpose, in the present invention, the rear wheel shaft 51 The reduction unit 50 is connected to the universal joint 41 connected to the transmission unit 40.

Thus, as the reduction unit 50 is separately installed on the rear wheel shaft 51, the transmission portion and the reduction and turning device are separated from each other, and the separation of the driving mission portion is accompanied by the weight reduction of the operation unit and the driving portion toward the rear of the vehicle. This results in placement, which eliminates weight imbalances and provides superior serviceability when required after maintenance due to separate missions.

In addition, there is an advantage that the power loss can be minimized by placing the reduction unit 50 on the rear wheel shaft 51 and adopting the rear wheel driving method instead of the front wheel driving method.

On the other hand, the multi-function agricultural machine power vehicle according to the present invention having the power transmission method and the driving method as described above has some improvements and supplements in the turning operation unit.

That is, although not specifically shown, by adopting an electronic mono lever lever necessary for the change of direction, such as to facilitate the change of direction, by adding a manual foot type conversion footrest than when the turning operation beyond the electric system is impossible Proactively responds to emergency turn operations.

Multi-functional agricultural machine power vehicle according to the present invention having the configuration as described above, by selecting and assembling in a suitable work machine shape on the loading unit 70 according to the work required in the farm, such as orchards, carriers, control, lift, It can be used for various types of working machines such as dumps.

For example, as shown in FIGS. 6 and 7, a loading box 90 having a predetermined frame is installed on the loading unit 70 to be used as the most basic transportation vehicle, and the loading box 90 is provided. The hydraulic cylinder 91 and the support 93 and the guide rail 92 for guiding the movement of the support 93 can be mounted to the lower end of the stacking box 90 and can be used as a lift and a dump. It is.

That is, the hydraulic cylinder 91 is driven by the hydraulic pressure supplied from a controller (not shown), and since it is used in general, a detailed description of its specific configuration and operation relationship will be omitted.

However, as shown in FIGS. 6 and 7, the loading box 90 may be lifted in the horizontal direction by the operation of the hydraulic cylinder 91, and thus, after loading the crops, the height of the vehicle may be adjusted according to the height of the vehicle. Not only can the lifting box 90 be lifted, but also can be used in various forms, such as to facilitate the transport of crops as needed.

That is, although not shown, it can also be used as a control unit by mounting a device that can control the loading unit 70.

The present invention has been described with reference to one embodiment shown in the drawings, but this is merely exemplary, and those skilled in the art will be able to implement various modifications and other equivalent embodiments therefrom.
