The present invention relates to a steering device of a multi-purpose farming machine used for various purposes such as carrying goods or harvesting fruits in rural areas, fishing villages, orchards, etc. More specifically, it is possible to adjust the height or change the direction. By implementing a farming machine, the present invention relates to a steering apparatus of a multi-purpose farming machine that can carry out tasks such as transporting fruit boxes, fertilizer bags, etc., or harvesting fruits at high places in orchards, rice fields, and fields.

In general, orchard farming involves fertilizing a large number of fruit trees, spraying pesticides, and continuing to manage the fruit trees, so that fruit can be harvested from the fruit trees.

For example, when pruning a fruit tree, the first time the fruit grows, the ladder is leaned against the tree, and the worker climbs the ladder and prunes or cuts.

In addition, when harvesting fruit from the fruit tree, a long pole or a ladder is used to drop the fruit placed at a high position.

When you manage the fruit trees in the orchard or harvest the fruits like this, you need to use a ladder to climb to a high place, so it is difficult and inconvenient to work, and there is a risk of accidents such as falling.

In addition, orchards, etc. to transport the harvested fruit or fertilize the fruit trees, the fruit box or fertilizer bag at this time is a heavy weight, so it is very inefficient to transport directly to the workforce.

For this reason, most of them use tractors and the like to efficiently transport items such as heavy fruit boxes and fertilizer bags. These tractors are equipped with trailers for storing harvested crops or fruits.

However, these tractors and trailers do not have any function other than a simple transportation means, so the ladders required for fruit harvesting should be separately prepared and used, which is uneconomical and has a high risk of safety accidents when handling separate ladders.

Recently, in order to easily harvest the highly open fruit when harvesting fruits in orchards, some of the types of trailers can be lifted by hydraulic devices (lifts in the form of X bars). Due to the complexity, the cost of installation is not small, which causes a lot of economic burden.

As such, in the orchard or the like, there is an urgent need for a cart means that can be freely operated and maneuverable. In particular, such cart means must not only be capable of safe maneuvering and driving even in the rough terrain of the orchard, In order to protect the environment, there must be conditions such as no emission of pollution, but until now, since there is no cart means exclusively used for orchards, the efficiency can be remarkably improved by replacing farm machinery for other purposes or relying only on manual work. There was a problem such as deterioration.

Therefore, the present invention has been devised in view of such a point, and therefore, a farm worker that can solve the above problems is required, and the structure that can be applied to such a farm worker is simple, but the manufacturing cost can be reduced as much as possible according to the establishment reality of the farm. It is an object of the present invention to develop a steering device to enable.

The present invention for achieving the above object is a farm work machine having a steering device capable of switching the direction by the operation of the handle, the steering device is a handle capable of rotating the shaft, and installed on the lower end of the shaft of the handle of two rows A steering drum for winding or releasing steering wires in opposite directions, and two rows each extending from the steering drum side to the left and right wheel sides while being guided by a plurality of steering rollers to allow rotation of the wheel. It characterized in that it comprises a steering wire and a link bar for interlocking the left and right wheels in the same direction.

Hereinafter, with reference to the accompanying drawings will be described in detail the multi-purpose farming machine according to an embodiment of the present invention.

1 and 2 illustrate a front perspective view and a rear perspective view, respectively, showing a multipurpose farming machine according to an embodiment of the present invention.

As shown in Fig. 1 and 2, the bottom of the trolley 15 made of a frame structure of the rectangular frame form a plurality of wheels 13 for driving the trolley, for example, four arranged at the corner of four bogies The wheel 13 is installed, and the upper part of the trolley 15 has an open handrail 26 formed of a combination of a vertical member of both sides and a horizontal member connecting the rear side of the vertical member, and the object or the harvested fruit Workbench 20 in the form of a square plate that can be used as a scaffold when loading or working is installed on top.

In addition, the trolley 15 has a battery for supplying power to the lower side of the work table 20 by installing a box on the frame, and driving motor 12 or work table 20 for driving each wheel 13. A switch (not shown) capable of controlling the lifting motor 16 or the like for lifting the blade) is provided.

In addition, the cart 15 is in the form of a frame structure consisting of a horizontal frame in the form of a rectangular frame and vertical frames disposed at four corners, and the vertical frame at this time guides the movement of the work table 20 when it is raised and lowered. It serves as a guide, and the horizontal frame plays a role of passage of the lifting wire 19 to be described later.

Therefore, while the battery is powered by the operator's switch operation, the trolley can be operated, and the work table can be raised and lowered.

The wheel 13 is assembled in such a way that it is supported in a rotatable structure on a wheel housing 27 having a substantially "a" shape installed at the bottom of the trolley, wherein the wheel housing 27 has a shaft ( It is installed in a structure that can be rotated together with the bushing while penetrating on the frame of 15).

That is, when the wheel housing 27 rotates in the horizontal direction about the axis, the wheel 13 assembled to the vertical member of the wheel housing 27 also rotates together.

At this time, the wheel housing 27 is integrally formed with a housing bar 29 extending a predetermined length toward the front of the truck, and the wheel housing as the link bar 24 of the steering apparatus 11, which will be described later, is coupled by a pin (27) can be rotated.

The present invention provides a drive device 14 that can drive the wheel 13 for the progress of the cart (15).

To this end, one side of the wheel housing 27 is provided with a driving motor 12 supported through a bracket or the like, and the shaft of the driving motor 12 at this time is connected to the shaft of the wheel 13 in a rotatable structure. .

Therefore, the wheel 13 can be driven by the force of the driving motor 12.

In the present invention, a mechanism for driving each wheel 13 independently by assigning one drive motor 12 to each wheel 13 is adopted.

In particular, the transmission path between the shaft of the wheel 13 and the shaft of the drive motor 12 is interposed with a worm reducer 24, that is, the wheel shaft and the motor shaft is a structure that is transmitted through the worm reducer motor When it is not driven, the worm reducer 24 can perform a brake role (restraining the rotation of the wheel), thereby eliminating problems such as the wheel shaking or spontaneously rolling during operation. This can be secured.

In addition, the present invention provides a steering apparatus 11 that can switch the progress of the cart 15 in the front and rear and left and right directions.

To this end, as shown in Figure 3, one side of the cart 15, for example, the front of the cart 15 is provided with a handle 10 having an axis that is installed in a rotatable structure while vertically penetrating the horizontal frame, etc. At the lower end of the shaft of the handle 10, a steering drum 22 having an upper and lower two-stage structure for winding or releasing two wires in opposite directions is integrally installed, and each of the steering drum 22 at this time is integrated. Two rows of steering wires 21, one of which is wound around and fixed to one end thereof, are guided by a pair of steering rollers 23 mounted on a roller bracket 28 on a horizontal frame to the left and right wheels 13, respectively. On the other hand, the steering wire 21 thus extended is connected to the end of the link bar 24 which is connected between the wheel-side housing bars 29 to link the left and right wheels 13 in the same direction. Connected.

Accordingly, when the operator turns the handle 10 to either side, the one side of the steering wire 21 is wound together and the other side of the steering wire 21 is released while the link bar is connected between the two wheels. Since 24 is moved to either the left or the right side, the wheels 13 on both sides rotate in the same direction by the movement of the link bar 24 at this time, so that the direction of the trolley 15 can be changed. As a result, the operator can drive the truck in the desired direction.

In addition, the present invention provides a means for easily performing a harvest operation for tall fruit, that is, a means for raising and lowering the workbench.

To this end, as shown in FIGS. 4 and 5, the elevating motor 16 is installed at the front and rear intermediate positions in the frame of the cart 15, and the shaft of the elevating motor 16 is substantially a motor. The shafts of the two lifting drums 17 connected to the shafts of the reducer, which extends to both sides of the motor, are arranged side by side in the front and rear directions of the truck and are supported by a bearing.

A total of four lines of lifting wires 19 are connected to each of the lifting drums 17, which are installed in two lines, and each lifting wire 19 at this time is a bogie through a predetermined path from the lifting drums 17. It is installed in an arrangement structure extending to the top of the vertical frame in the four corners of (15) can be raised or lowered while supporting the four places of the worktable 20 in a balanced and stable manner.

For example, two lines connected to the drum located in front of the two lifting drums 17 are extended to the left and right sides, respectively, and at the same time, they are extended in the forward direction by using the lifting rollers 18 to move forward. After passing through the lifting rollers 18 provided with the left and right edges, respectively, it is extended upward again and fixed to the upper end of the vertical frame of the trolley 15.

That is, the front left and right edges of the work bench 20 are supported in the form supported by the elevating wire 19 via the elevating roller 18.

Similarly, two lines connected to the drum located at the rear side of the two lifting drums 17 extend to the left and right sides, respectively, and are extended to the rear using the lifting rollers 18 to extend to the rear, and to the rear left and right edges of the work bench. After passing through each of the lifting rollers 18 provided in each of them, it is extended upward again and fixed to the upper end of the vertical frame of the trolley 15.

Accordingly, the work table 20 can be supported in four corners in a balanced manner by the four wires for lifting (19).

Particularly, in the arrangement form of the elevating wire 19, the remaining sections except for the straight section extending from the drum to the left and right sides are arranged in the form of a horizontal frame of the trolley 15, and between the vertical frame and the workbench vertical member. As it is disposed in the form of a gap through the gap, most of the lifting wires are not exposed to the outside, thereby neatly arranging the exterior of the bogie, and also eliminating interference due to wires with the surroundings.

In this case, the two wires connected to the one drum are connected in the form of being wound in opposite directions so that the two wires can be wound or unwound together when the drum rotates.

Therefore, as shown in FIG. 6, when raising the work platform, when the lifting motor 16 rotates in the forward direction, four rows of lifting wires 19 are simultaneously wound on each lifting drum 17. As the length of the wire is shortened, the worktable 20 can be lifted and lifted up.

When the work platform is lowered, when the lifting motor 16 rotates in the reverse direction, the four rows of lifting wires 19 wound on the lifting drums 17 are released, and at the same time, the work platform 20 itself The load can be lowered down.

Thus, in the case of the multi-purpose farming machine provided by the present invention, the fruit can be harvested in an orchard, etc., so that the trolley can be easily moved in a desired direction by operating a handle, so that the work can be performed quickly and conveniently in a large work area. The height of the workbench can be increased, and the worker can raise the efficiency of the work, such as the easier harvesting of the open fruit in the high place while standing on it, so that the worker can perform the work in the easier working condition. Can be.

As described above, while implementing a new type of agricultural work machine including a bogie capable of changing direction and moving, a worktable capable of raising and lowering, and the like, the configuration of the steering system can be simplified and the manufacturing cost can be reduced as much as possible. There are advantages to it.
