The present invention relates to a passenger rice transplanter, and more particularly, to a passenger rice transplanter having a structure greatly improved workability by excluding the lever-shaped operation means.

According to FIG. 1 showing a general-purpose passenger rice transplanter, the passenger rice transplanter 1 includes an engine 11, a driver's seat 12, a front wheel 13, a rear wheel 14, a brake pedal 15, an instrument panel and The main body 10 includes a panel and the like, and a moving work unit 20 including a mother mounting base 21 and a float 22, and the like, which are divided into two parts. It is connected in a swingable state.

On the other hand, the paddy field in which the rice transplanting operation is performed is a solid rice paddle surface in which the front wheels 13 and the rear wheels 14 roll on the top, and the submerged soft water dragged while the float 22 touches the surface. Consists of soil

That is, the front wheels 13 and the rear wheels 14 moving the traveling main body 10 oscillate on the rugged half, while the float 22 constituting the rice transplanter 20 is submerged soft soil, That is, it makes the surface of the mud flat in water and moves without relatively big fluctuations.

During the transplanting operation, the implanter 23 disposed at the lower end of the transplanting working unit 20 continues to move a certain amount of hair every time from the mother mounting table 21 and transfer it to a proper depth in the mud. This operation is the basis of the rice transplantation work by the machine.

By the way, while the whole moving main body 10 including the front wheel 13 and the rear wheel 14 is rocking over the bumpy surface, the moving work unit including the mother mount 21 and the implanter 23. 20 should be planted to a certain depth at all times irrespective of the fluctuation of the traveling main body 10.

On the other hand, in order to allow the rice transplanter 20 to perform a rice transplanting operation of a predetermined depth irrespective of the swing of the traveling main body 10, a driver's seat 12 on the traveling main body 10 is usually placed in the vicinity of the driver's seat 12. In addition to the moving work base lifting lever 16 (hereinafter referred to as "lifting lever"), a swing lever 17 for automatic transfer control (hereinafter referred to as "swing lever") is provided.

The lifting lever 16 is disposed on the side of the driver's seat 12, while the swing lever 17 is disposed directly below the steering wheel.

More specifically, the lifting lever 16 is a normal manual lever, and moves along the lifting lever operation path shown in FIG. The motion corresponding to the stop position is made.

The elevating lever operation path is divided into two parts, one of which corresponds to the "automatic" position on the drawing, in which the rising or falling of the moving work machine is controlled by an automatic control device as described later. And the other is the part from the "rising" position on the operation path to the "implantation" position, that is, the control portion by manual operation.

In addition, the swing lever 17 is a kind of a multi-contact lever, and functions only when the lifting lever 16 is in the " automatic " position.

That is, when the lifting lever 16 is placed in the "auto" position, when the operator presses the swing lever 17 in the up and down direction, the lowering of the moving work unit 20 and the connection of the moving clutch are performed in the pressing order. As a result, there is an effect that the lifting lever does not need to be operated by the lift lever in order to control the lifting and lowering of the cutting operation part 20 as well as the moving clutch during the busy moving operation.

The lifting lever 16 and the swing lever 17 are attached with respective sensors such as an upper limit switch on the rear wheel fender 19 and a float sensor on the float 22. The sensor sends the measurement or detection result to the central controller (not shown) under the driver's seat.

On the other hand, the swing lever 17 has a function of controlling the unfolding of the line marker 24 in addition to the function of controlling the rise and fall of the rice transplanter 20 and the connection and disconnection of the tooth clutch.

That is, when the swing lever 17 is pushed or pulled in the front-rear direction, either one of the left and right scribe markers 24 is unfolded.

For example, when the rocking lever 17 is pushed forward, the left line drawing marker is unfolded, while when it is pulled backward, the right line drawing marker is unfolded.

In contrast to this unfolding process, these left and right scribing markers are arranged to be folded by the link operation when the rice transplanting base is raised.

Looking at the lever arrangement around the driver's seat 12 in the conventional passenger rice transplanter 1, another lever called the HST shift lever 18 is disposed to the left of the driver's seat, which is a transmission case. (transmission case) It functions to control the traveling speed of passenger rice transplanter 1 itself by being connected with hydraulic continuously variable transmission.

As such, three levers 16, 17, and 18 are disposed around the driver's seat 12 of the conventional passenger rice transplanter 1, and the worker has to alternate between and sometimes simultaneously operate these multiple levers during the cutting operation.

In a word, the conventional rice transplanter 1 has a problem of poor workability despite the high level of automatic control device due to the cumbersome operation of the lever.

In addition, the left and right scribing markers 24 are extended by operating the swing lever 17 in the front-rear direction. For an inexperienced worker, the "back and forth" on the swing lever operation and the "left and right" on the drift marker operation. "There was a lot of confusion between them and mishandling them.

In order to solve the above problems due to the arrangement of a plurality of operating levers around the driver's seat, the Applicant eliminated the lifting lever and the swinging lever by providing a moving part control button and a drawing marker control button on the HST shift lever. Has developed and filed a patent for a passenger rice transplanter. (Korean Patent Application No. 10-2004-0075790)

However, even if the patent application filed by the applicant of the patented passenger rice transplanter, the inconvenience of having to operate the HST shift lever, especially while paying attention to the steering due to the rugged situation, still remains.

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a traveling rice transplanter with a significantly improved workability according to a more rational control system without any type of operation lever.

Specifically, it is an object of the present invention to provide a passenger transplanter having a structure in which all operations, including traveling shifts, are made through the buttons on the steering wheel and the pedals on the deck, or only through the buttons on the steering wheel.

The object of the present invention as described above is achieved by incorporating a part or all of the conventional lifting lever function and the swing lever function on the steering wheel.

The rice transplanter of the present invention is characterized in that a plurality of operating lever functions are added to a steering wheel, and are basically divided into two types of embodiments, one of which adds only a moving work unit lifting control function to a steering wheel. Another case is a case where a moving work unit lifting control function and a drawing marker spreading control function are added together on the steering wheel.

That is, the passenger transplanter according to the first embodiment of the present invention is provided with a button for controlling the moving work unit on the steering wheel, and a line marker control button and an automatic / manual selection switch are arranged at appropriate positions around the driver's seat. .

In addition, the passenger transplanter according to the second embodiment of the present invention is provided with a button for controlling the moving part and a drawing marker control button on the steering wheel, while the automatic / manual selection switch is arranged in a proper position around the driver's seat to be.

On the other hand, a panel in front of the driver's seat may be preferable as the proper position for arranging the above-mentioned marker marker control button or automatic / manual selection switch, but may be any other position within the range in which the operator's hand or foot can be operated or other shapes other than the buttons. Do.

For example, the button for controlling the scribe marker in the first embodiment may be arranged next to the brake pedal on the right deck in the form of a pedal.

According to any of the above two embodiments, the transfer operation control is performed by a button on the steering wheel, while the HST shift pedal operation is performed by a pedal on the deck, so that any form of lever operation is not necessary during the transfer operation. do.

In other words, after the operator determines the control mode through the automatic / manual selection switch operation, the operator only needs to press the button or press the pedal as necessary while maintaining the steering wheel holding state.

As will be described later, in any of the "automatic" or "manual", a kind of safety that automatically stops the lifting and lowering of the rice transplanter when the button operation state lasts for a predetermined time due to an operator's mistake or mechanical failure. The device is provided.

Hereinafter, a passenger rice transplanter of an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

According to FIG. 3 showing the passenger rice transplanter of the embodiment of the present invention and FIG. 4, which is a plan view of the passenger rice transplanter according to the first embodiment, the steering wheel 251 has no steering lever 251 while there is no form of an operating lever around the driver's seat 120. The moving part base control button 251-1 is provided on the panel, and the line marker control button 160 and the automatic / manual selection switch 150 are provided on the panel in front of the driver's seat.

In addition, the shift pedal 180 is disposed on the left deck, and serves to control acceleration and deceleration as well as forward and reverse of the traveling speed.

As shown in FIG. 5 (a), which is a plan view of the steering wheel 251 in the passenger transplanter according to the first embodiment, two units marked as “up” and “down” at the right end of the steering wheel 251. The moving part base control button 251-1 which consists of buttons a and b is arrange | positioned.

The unit button (a) raises the loom work base, while the unit button (b) serves to lower the loom work base.

Thereby, the operator can control the lifting of the rice transplanter with the right thumb while operating the steering wheel to get the direction.

In addition, when it is necessary to fold the scribing marker according to the completion of one row of transplanting operations, if the steering wheel is held with the right hand and the left hand operates the scribing marker control button 160 with the left hand, do.

Meanwhile, as mentioned above, the passenger transplanter of the second embodiment of the present invention has a feature that a button for controlling the moving work unit and a button for controlling the marker line are provided on the steering wheel.

That is, as shown in FIG. 5 (b), which is a plan view of the steering wheel in the passenger transplanter according to the second embodiment, two unit buttons marked "up" and "down" are also displayed at the right end of the steering wheel 252. FIG. The moving work unit control button 252-1 composed of (a, b) is disposed, while two unit buttons (c, d) marked "left" and "right" at the left end of the steering wheel 252. The scribing marker control button 252-2 which consists of this is arrange | positioned.

The unit button c spreads out the left line drawing marker, while the unit button d serves to spread out the right line drawing marker.

Thereby, the operator can control the lifting of the rice transplanter with the right thumb, and control the unfolding of the scribing marker with the left thumb while manipulating the steering wheel.

That is, in the case of the second embodiment, the operator performs the rice transplanting operation with a pleasant feeling as if handling the joystick of the game machine, without having to take his hand off the steering wheel.

From this point of view, the passenger transplanter according to the first embodiment, in which only the moving part control button 251-1 is disposed on the steering wheel, may not have any confusion in button operation. In the case of the second embodiment to feel, there is an absurdity that is less work convenience.

For reference, in the case of the second embodiment, as the rotation angle of the steering wheel 252 increases, the initial positions of the moving part control button 252-1 and the line marker control button 252-2 are reversed. It may be a problem, that is, a button manipulation mistake due to the moving part control button 252-1 to the left end of the steering wheel and the line marker control button 252-2 to the right end of the steering wheel may be concerned. It is not necessary to assume or consider such a case due to the nature of the transplanting work that is not known along straight lines.

As described above, in the passenger rice transplanter of the first and second embodiments of the present invention, the rice transplanter control function is added to the steering wheels 251 and 252, or the drawing marker control function is added thereto. By deleting all the operation means, the operator only has to pay attention to the steering wheel, the workability is greatly improved compared to the conventional, which has been cumbersome to operate several levers at the same time busy.

On the other hand, the automatic / manual selection switch 150 disposed on the panel in front of the driver's seat serves to determine the automatic or manual control mode of the bar, which will be described later, the operator at the beginning of the transfer operation, the operation of the operation by It is common to select the control mode first.

Therefore, since it is not necessary to operate relatively frequently during operations like the moving part control buttons 251-1 and 252-1 or the line marker control button 252-2, it is separated from the group of buttons on the steering wheels 251 and 252. Even if placed, there is no inconvenience in working.

Unlike the drawing, the automatic / manual selection switch 170 may also be disposed on the steering wheels 251 and 252.

In the passenger transplanter according to the embodiment of the present invention, the HST shift pedal has a structure in which a support shaft is connected to an HST case (not shown) through a link structure, and the HST shift pedal 180 of FIG. Stepping on the first half (F) is the forward acceleration, stepping on the second half (R) is the rear acceleration is made.

The shift structure by the pedal and the link mechanism is well known in the art and related industries, and various types of link structures may be adopted by those skilled in the art, and thus, the present invention is not limited thereto.

For example, if you want to adopt the traveling shift detecting means having the same structure as in the Republic of Korea Patent Application No. 10-2004-0075790, in the patent application, instead of deleting the shift lever on the accompanying drawing (Fig. 5), the traveling shift The remaining portion such as the variable resistor as the sensing means may be connected to the support shaft portion of the shift pedal 180 while maintaining the same.

6 (a) to 6 (c) are flowcharts showing control logic for the rice transplanter in the passenger rice transplanter of the embodiment of the present invention.

6 (a) to 6 (c) are the same as the contents of the above-mentioned Korean Patent Application No. 10-2004-0075790, but are cited herein to describe the entire control logic of a passenger rice transplanter according to the embodiment of the present invention. do.

The control logic is usually realized by a control program input to a microcomputer inside an automatic control device mounted below the dashboard or the driver's seat.

To aid in understanding, what is meant by "switch" or "sensor" on the flowchart is explained first.

The "rising switch" is a switch connected to the unit button (a) of the two unit buttons (a, b) constituting the moving work unit control buttons (251-1, 252-1) on the steering handle (251, 252). When the switch is connected, the rice transplanter is raised. (Hereinafter, the operation of the unit button a is expressed by the connection of the "rising switch")

"Down switch" is a switch connected to the unit button (b) of the moving parts control buttons (251-1, 252-1) on the steering wheel (251, 252), when the switch is connected, the moving part is lowered Done. (Hereinafter, the operation of the unit button b is expressed by the connection of the "falling switch")

"Float sensor" is a sensor disposed adjacent to the float at the bottom of the rice transplanter, and serves to detect whether the float is in contact with the ground.

That is, the fact that the signal value from the float sensor reaches the set value indicates that the rice transplanter including the float touches the ground.

The "upper limit switch" is a switch disposed adjacent to the rear wheel panda behind the traveling main body, and serves to detect whether the upper limit position of the rice transplanter is reached.

That is to say that this switch is connected indicates that the rice transplanter has risen to the upper limit position.

The "HST pedal sensor", as mentioned above, is a traveling shift detecting means provided at the lower end of the HST shift pedal, and has a function of detecting a traveling shift state of the passenger rice transplanter itself. It informs the automatic control device whether it is driving or reversing.

Hereinafter, each flowchart is explained in full detail.

Fig. 6A is a flowchart relating to the descent control logic, and shows each step of controlling the descent operation of the rice transplanter.

The "automatic / manual selection switch" ON "?" Step in the flowchart is a step for checking whether the "automatic" or "manual" is in the rice transplanter control mode. If "yes", the control of the rice transplanter is performed. If the mode is "auto" while "no", the control mode is "manual".

As shown on the flowchart, when the operator presses the "down" switch while the auto / manual selection switch is connected to "automatic", the moving part is energized to the descending solenoid and the float sensor The descent will continue until the setpoint is reached (on the mud surface in the water).

It should be noted here that when the "falling" switch is pressed for a predetermined time ("5 seconds" on the flowchart), the rice transplanter is not simply lowered, but is connected with the descending motion. As soon as it touches the ground, it is possible to move immediately.

This is one of the features of the present invention, it can be said to be a preferred form of control that realizes the operator's prompt work start very effectively.

In addition, as mentioned above, when the "falling" switch is connected for a predetermined time ("5 seconds" on the flowchart) due to an operator's mistake or mechanical failure, the automatic control device is energized to the descending solenoid. By releasing the state, further stops the transfer of the rice transplanter.

In the manual control mode shown on the right side of the flowchart, the rice transplanter continues to descend until the worker releases the "falling" switch.

In the manual control mode, in consideration of the fact that the moving solenoid does not cause breakage even if the descending solenoid continues to operate even though the moving work unit is in contact with the mud surface in the water, the lowering solenoid is operated as in the automatic control mode. It does not force the furnace off.

Of course, as in the automatic control mode, the control logic of the form of forcibly releasing the energized state to the falling solenoid may be used when the "falling" switch is connected for a predetermined time (for example, "5 seconds").

Fig. 6 (b) is a flowchart relating to the lift control logic, and shows each step of controlling the lift operation of the rice transplanter.

The meaning of the " auto / manual selection switch " ON " " step on the flowchart is the same as in the down control logic of Fig. 7A.

As shown on the flowchart, when the operator operates the "rising" switch while the automatic / manual selection switch is pressed "automatic", the moving work unit is energized to the rising solenoid and the upper limit limit on the rear panda. The climb will continue until the switch is connected.

On the other hand, in raising the rice transplanting work base, the power transmission to the rice transplanting work base is completely interrupted by first cutting the rice transplant clutch.

Thus, of course, an isoclutch lamp having a function as a kind of indicator is turned on.

As in the case of the lowering control logic, when the "rising" switch is connected for a predetermined time ("5 seconds" on the flowchart) due to an operator's mistake or failure, the automatic control device is energized to the rising solenoid. Forcibly releasing the state stops further rice transplants.

The manual control mode shown on the left side of the flowchart is also the same as that of the automatic control mode, in order to reliably prevent serious damage to the rice transplanter caused by excessive rise of the rice transplanter regardless of whether the control mode is automatic or manual. to be.

The difference between the automatic control mode and the manual control mode in the lift control logic is that the upper limit switch recognizes the rising limit of the moving work machine in the automatic control mode, whereas the manual control mode leaves it to the operator's judgment. Is the point.

Fig. 6 (c) is a flowchart relating to the reverse ascent control logic, and shows each step of controlling the moving work unit raising operation at the time of the traveling main body backward.

The meaning of the " auto / manual selection switch " ON " " step on the flowchart is the same as in the rise control and fall control logic of Figs. 6 (a) and 6 (b).

As shown on the flowchart, when the operator presses the HST shift pedal to the reverse position while the automatic / manual selection switch is connected to "automatic", an alarm sounds and at the same time, the moving part is transferred to the rising solenoid. With the energization, the upper limit switch on the rear wheel panda is raised until it is connected.

That is, in order not to damage the rice transplanter by the reverse of the traveling main body, the HST shift pedal is in the reverse position and at the same time raises the whole transplant worker.

However, there are cases in which a special operation such as selecting a mud surface in the water is performed with the float while reversing a passenger rice transplanter. Thus, in such a case, the automatic / manual selection switch is connected to "manual", that is, manual. Under the control mode, the alarm sound output and the rice transplanter lift did not occur even when the travel body was retracted.

In other words, at least under the manual control mode, the operator can determine whether the rice transplanter is raised by situation.

FIG. 7 is a view schematically showing the overall control system of a passenger rice transplanter according to an embodiment of the present invention. The automatic control device, that is, the central control device 300, as described above, has an automatic / manual selection switch on its input side. 301, an upper limit limit switch 302, an HST pedal sensor 303, and a float detection sensor 304 are arranged, while on the output side thereof, an isoclutch relay 350, a marker relay (left and right) 351 and a lift It forms a structure in which / the solenoid 352 is disposed respectively.

In the case of the automatic / manual selection switch 301, only 301 is attached in consideration of the relationship between components in the serial numbering, and is the same as the automatic / manual selection switch 170 mentioned above.

As mentioned above, although the riding rice transplanter of the Example of this invention was demonstrated in detail, it is believed that a person skilled in the art can add a structural change unless it deviates from the basic meaning of this invention.

For example, while maintaining the basic structure of the present invention as it is, it may be assumed that the electrical connection between the button for controlling the moving work unit and the button for controlling the drawing marker and the automatic control device.

However, it will be understood that minor structural changes, such as a structure in which the operation lever is deleted by incorporating some or all of the conventional lifting lever function and the swing lever function on the steering wheel, are within the technical scope of the present invention.

As described above, according to the present invention, by incorporating a part or all of the conventional lifting lever function and the swing lever function on the steering wheel, all operations including driving shifting are made through the buttons on the steering wheel and the pedals on the deck. Passenger rice transplanter of structure can be obtained.

More specifically, as the overall moving work control is performed only by the buttons on the steering wheel and the pedal operation on the deck without any type of operation lever, a significantly higher workability improvement effect is achieved.

In particular, in the passenger rice transplanter of the second embodiment in which the rice transplanter control button and the drawer marker button are disposed at the left and right ends of the steering wheel, respectively, the rice transplanter control level is significantly increased, and a considerable effort is required. It is another big meaning that transforms the character of this work.
