Description

Engine RPM control device and method of Combine connected auger drive}

The present invention relates to an apparatus and method for controlling engine RPM of a combine linked to an auger operation, and more particularly, an auger driving unit due to high-speed running of the combine while the auger (discharge device) is moving to a set grain discharging position or initial storage position. It relates to an engine RPM control apparatus and method of a combine linked to an auger operation to prevent damage or damage.

Combines are well known as agricultural machinery that simultaneously mow, threshing and sorting crops while moving. The combine is equipped with a mowing unit that cuts the crops in front of the running body that can be maneuverable from front to back, left and right, and the crops cut through the mowing unit are returned to the side of the running gas, and a series of threshing, sorting, straw treatment and discharge, etc. It is designed to be able to perform the process continuously.

The harvesting part of the combine includes a mowing means that cuts the bottom of the stem of the crop to a certain height from the ground. Preferably, two sets of bariquant type mowing machines with opposite operating directions are provided, and crops cut by the mowing machine Is safely conveyed to the traveling gas side through a conveying means constituting the harvesting unit, and a predetermined threshing treatment is performed on the crops harvested from the traveling gas side.

The running gas is provided with a grain tank including a threshing unit for dropping grain from the conveyed crops, a sorting unit under the threshing unit for sorting foreign substances such as straw mixed with grains, and a storage unit for storing the sorted grains. In addition, a discharge device called'unloader' or'auger' (hereinafter referred to as'auger') is installed to discharge the grain stored in the grain tank to an appropriate external loading means.

Accordingly, the grain supplied from the harvesting section and threshed through the threshing section passes through the sorting section below the threshing section and is transported to the storage section of the grain tank after sorting to filter out foreign substances such as gumbul, and temporarily stored. The auger is discharged to an appropriate external loading means according to the discharge operation of the auger performed by the operator.

The auger for discharging the grain stored in the grain tank is generally adjusted in position through a wireless operation such as a wired operation through a cross-shaped swing lever or a short distance remote operation using a wireless controller. That is, the auger can be moved up and down to a desired height through wired and wireless operation, and rotated left and right with respect to the horizontal direction to position the auger at a desired location across the initial storage position and the grain discharge position.

On the other hand, in the case of a recent high-spec combine, in returning the auger manipulated to the discharging position for grain discharging to the original initial storage position after the discharging operation is completed, operation fatigue due to repeated operation when it is not accurately stored in the designated position and In order to prevent delays in work, etc., an automatic return function is installed that automatically moves the auger from the grain discharging position to the initial storage position.

In addition, it is equipped with an automatic discharge function that automatically moves the auger from the initial storage position to the grain discharge position outside the gas with a simple switch operation. The automatic discharge function is also one of the convenience features that can improve work efficiency while providing operational convenience, as it is to alleviate operation fatigue due to repetitive auger operation and prevent work delay due to auger operation.

The automatic return function or automatic discharge function is basically implemented through one-touch switch operation. With the start signal outputted when the switch is operated, the operation unit constituting the control means determines the target value and the corresponding control value based on the current position of the auger, and controls the auger drive unit with the determined control value to control the target position (storing position). Or the auger can be moved to the discharge position) at once.

As such, the automatic return function or automatic discharge function of the auger can automatically move the auger to the target position with only one switch operation, so there is a great advantage in terms of operation convenience and work efficiency. However, if the gas is driven at high speed while the automatic return or automatic discharge function is being executed, or the auger driving device is damaged or damaged when the aircraft is turned to the left/right side during high speed driving in the function execution state.

Move the auger when the aircraft is traveling at high speed while the automatic return or automatic evacuation function is running, or when a steering operation that turns the aircraft to the left or right while driving at high speed with the automatic return or automatic evacuation function is running. This is because a large load is instantaneously placed on the auger drive device (auger motor) that generates the power for this.

For example, as in the example of FIG. 1, when the auger is rotated at a high speed with respect to the direction in which the auger 600 rotates in a state in which the auger automatic return function is being executed (the auger is rotating), the auger rotates. A large centrifugal force acts on the auger in the direction opposite to the intended direction, and accordingly, a force in the reverse direction is applied to the auger driving device 700 at an instant, so that the auger driving device may be damaged or damaged.

It can be controlled to run with a lowering control.

In addition, the control unit applied to the present invention performs control of returning the engine RPM to the original RPM set by the accelerator lever when a set time elapses from the control execution point of forcibly lowering the engine RPM, or when the auger operation is not detected. can do.

With reference to these drawings, the overall configuration of the combine to which the engine RPM control apparatus according to an embodiment of the present invention is applied will be described first.

2 to 4, the combine to which the engine RPM control apparatus according to an embodiment of the present invention is applied is largely composed of a body 1 and a harvesting part 3 in front of the body 1. The body 1 has a pair of left and right crawler-type running wheels 2 that are independently driven, and the mowing part 3 is provided through the mowing frame 32 installed at the front end of the running body 1. It is connected to the front side of 1) so that it can be lifted.

The mowing unit 3 is provided with two sets of bariquant type mowing machines in which the operating directions are opposite. The crops cut by the harvesting machine are safely conveyed to the supply chain 4 on the side of the gas 1 through the conveying means (not shown) constituting the harvesting section 3, and the crops 1 by the supply chain 4 It is moved to the threshing/selecting device 8 on one side (the left side of the aircraft when viewed from the plane).

While passing through the threshing/sorting device 8, a sorting operation is performed to filter out sheds and straws, etc., which were included along with the grains of the threshed crops, at the same time as the threshing of the ear of the crop. And the grains finally sorted through the sorting process are returned to the grain tank 9 inside the other side of the gas and stored, and discharged out of the gas 1 through an auger 6, which is a grain discharging device according to the operator's discharge operation. .

Operation related to the lifting and running of the cutting unit 3 is performed through a lever of the gas operation unit 7 provided in front of the other side of the aircraft 1, and the gas operation unit 7, that is, below the driver's seat and the grain tank ( 9) In a predetermined space formed therebetween, an engine 10 that substantially generates an output for driving a vehicle and driving various devices provided in the combine is disposed.

It is mounted transversely in the space so as to face the left and right width directions of the body 1. In addition, the dust cover assembly 11 is installed to open and close the side opening of the space in which the engine 10 is mounted.

5 is a perspective view of an auger (grain discharging device) mounted on the combine shown in FIGS. 2 to 4.

Referring to FIG. 5, the auger 6 for external discharge of grain includes a grain discharging unit 60 through which grain is finally discharged, a horizontal transport container 62 connected to the grain discharging unit 60, and a grain tank 9 ) It includes a vertical transfer container 64 extending from the rear side in the height direction of the gas, and includes a joint part 63 that connects the horizontal transfer container 62 and the vertical transfer container 64 to enable grain transfer.

The joint part 63 is provided with an elevating driving unit (not shown), for example, an elevating cylinder for elevating the horizontal conveying cylinder 62 in the height direction of the vehicle with respect to the vertical conveying cylinder 64. And in the vertical transfer container 64, the horizontal direction of the auger 6 is positioned so that the horizontal transfer container 62 and the grain discharging unit 60 are rotated in a horizontal direction so that the grain can be accurately discharged to an arbitrary discharging position outside the gas. It is provided with a rotation driving unit 105 to adjust.

Grain is conveyed vertically through a vertical conveying container 64 and a horizontal conveying container 62, and a rotating screw (not shown) installed in each of the joint parts 63, through a vertical conveying container 64, a joint part 63, and horizontal conveying. It is conveyed to the barrel 62 and is finally discharged through the grain discharging unit 60, and the rotating screw is helical on the outer edge of the rotating shaft which is rotatably disposed in the respective conveying barrels 62, 63, 64 and the joint unit 63. It may be a known configuration in which the blade is formed.

The rotation driving unit 105 is composed of an auger motor 110 and a reducer 112 that transmits the rotational force of the auger motor 110 to the horizontal conveyer 62. The auger motor 110 transmits the rotational force to the reducer 112 under the control of the control unit according to the horizontal direction operation command of the operator through a wired/wireless controller, etc., and the reduced rotational force output from the reducer 112 is used for the auger 6 The horizontal position is adjusted.

The rotation driving unit 105 adjusts the horizontal position of the auger 6 according to a manual control operation through a wired or wireless controller. In addition, the horizontal position of the auger 6 is also adjusted by automatic control operation through a wired or wireless controller. The automatic control operation includes automatically returning the auger to the initial storage position after the grain discharge operation is completed, and automatic discharge operation of automatically moving the auger 6 from the initial storage position to the discharge position outside the gas.

The automatic return or automatic discharge function of the auger 6 to the initial storage position is basically implemented through a one-touch switch operation. Target position by determining the target value and the corresponding control value based on the current position of the auger 6 with the start signal outputted when the corresponding switch is operated, and controlling the auger drive unit with the determined control value. You can move the auger to the storage position or discharge position at once.

However, when the gas is driven at high speed while the automatic return or automatic discharge function is being executed, or the gas is rotated during high speed driving in the function execution state, the auger driving device, more specifically, the auger motor 110 may be damaged or damaged. I can. This is because a large load is instantaneously placed on the auger motor 110 when the auger runs at high speed while the auger rotates in the horizontal direction or when the aircraft is turned left/right.

The present invention is to solve such a conventional problem, and if the vehicle speed is greater than or equal to the set vehicle speed while the auger is in operation, the auger is horizontal by forcibly lowering the engine RPM to decelerate the vehicle speed, such as automatic return or automatic discharge function execution. This is to prevent damage or damage to the auger driving device due to the rotation operation of the combine during high-speed driving or high-speed driving in the state of rotating in the direction.

Hereinafter, an apparatus for controlling engine RPM of a combine according to an aspect of the present invention will be described with reference to FIG. 6.

6 is a schematic diagram of an engine RPM control apparatus of a combine according to an embodiment of the present invention.

Referring to FIG. 6, an engine RPM control apparatus for a combine according to an embodiment of the present invention includes a motion detection unit 115 for detecting a rotational motion of an auger, and a vehicle speed detection unit 120 for detecting a vehicle speed of the combine. . In addition, a control unit 130 is provided that receives operation information of the auger 6 output from the motion detection unit 115 and vehicle speed information output from the vehicle speed detection unit 120 and performs a predetermined engine RPM control.

The motion detection unit 115 detects the rotational motion of the auger, and when the rotational motion is detected, outputs the corresponding information to the control unit 130 in the form of an electric signal. The motion detection unit 115 automatically discharges the grains through the auger 6 or automatically returns the auger storage position from the on/off state of the auger automatic discharge/return switch 170 to which an execution command is input. It can detect rotating motion.

In some cases, the auger 6 is output from a drive signal of the auger motor 110 that drives the auger 6 to rotate left and right or the output signal of a rotation angle sensor (not shown) that detects the horizontal rotation angle of the auger 6 ) May be configured to detect a rotational motion. This is because the auger motor 110 is continuously driven during the auger rotation, and the rotation angle sensor also continuously outputs a detection signal according to the change in the rotation position of the auger.

The vehicle speed detection unit 120 may be a sensor that detects all known vehicle speeds, including a reed switch type, a photoelectric type, and an electronic type. The reed switch type, photoelectric type, electronic vehicle speed sensor, etc. classified according to the vehicle speed detection method are all known configurations. Therefore, a detailed description thereof will be omitted.

The control unit 130 analyzes the operation information of the auger output from the motion detection unit 115 and the vehicle speed information output from the vehicle speed detection unit 120, and performs a corresponding engine control according to the analysis result. Preferably, when the rotational motion of the auger is sensed by the motion detection unit 115 and the detected current vehicle speed is greater than or equal to the set vehicle speed stored in the memory, the current engine RPM is forcibly lowered to the set RPM to reduce the vehicle speed. do.

The set RPM may be, for example, an idle RPM. Of course, it is not limited to children RPM. An RPM region generating a vehicle speed that does not give a large impact to the auger motor 110 is sufficient. For example, in consideration of the weight and turning radius of the horizontal carrier, the performance or specifications of the auger motor 110, durability, etc., the auger motor 110 may be an RPM that maintains a vehicle speed at a level capable of being normally driven.

In the case of an electronic engine, since direct engine control is possible through the control unit 130, for example, an ECU, control for forcibly lowering the engine RPM when rotating the auger can be easily implemented with only software setting, and in the case of the mechanical engine 160 For example, as illustrated in FIG. 6, the accelerator motor 140 operated under the control of the controller 130 may be implemented through a configuration that automatically adjusts the position of the accelerator lever 150.

The control unit 130 may also perform a control for forcibly lowering the engine RPM, as well as a control for awakening the alertness through the warning means 180 so that the driver recognizes that there is a danger situation and takes a quick follow-up action. For example, the driver can immediately recognize the danger of a dangerous situation by controlling the alarm sound output through the alarm sound output device or the warning message output control through the display device.

On the other hand, the control unit 130 stops the operation after a set time has elapsed from the control execution point of forcibly lowering the engine RPM, or the auger is normally moved to a preset automatic discharge position or initial storage position while driving at low speed through forced control of the engine RPM. When this is detected, control is performed to return the engine RPM to the original RPM set by the accelerator lever 150.

Stopping the operation of the auger 6 can be determined from whether the control unit 130 outputs a driving signal output to the auger motor 110 or a signal output from a rotation angle sensor that detects the horizontal rotation angle of the auger. Stopping the operation of the auger 6 means a state in which the driving signal output from the control unit 130 to the auger motor 110 is blocked, and when the operation of the auger 6 stops, the rotation angle sensor also does not output a detection signal. Because.

In some cases, a sensor is added to the auger seat (not shown) that mounts and fixes the auger 6 in the initial storage position, and the sensor outputs when the auger 6 is normally seated on the auger seat. The control unit 130 receives the signal and recognizes that the auger is stopped, and a corresponding follow-up control, that is, a control for returning the engine RPM to the original RPM set by the accelerator lever may be performed.

Hereinafter, the engine RPM control process performed by the above-described engine RPM control device of the combine, that is, the engine RPM control method of the combine according to another aspect of the present invention will be described with reference to the flowchart of FIG. 7. For convenience of explanation, the configurations illustrated in FIGS. 2 to 6 described above will be described with reference to the corresponding reference numerals.

Referring to FIG. 7, a method of controlling engine RPM of a combine according to another aspect of the present invention includes a motion detection step (S100) of acquiring information on a rotational motion of the auger 6. The information on the rotational operation of the auger 6 may be information on whether the auger is in the rotational state, and the on/off state of the auger automatic discharge/return switch 170, whether the auger motor 110 drive signal is output, the above It can be obtained from whether one rotation angle sensor outputs a signal.

A method for controlling engine RPM of a combine according to another aspect of the present invention also includes a vehicle speed detection step (S200) of acquiring information on a current vehicle speed of the combine. Information about the vehicle speed can be obtained through analysis of a signal output from the known vehicle speed sensor. In some cases, information about the vehicle speed may be substituted with information about the engine RPM.

After the vehicle speed detection step S200, a determination step S300 of determining whether to control the RPM of the engine is successively performed. In the determination step (S300), the information acquired in the motion detection step (S100) and the vehicle speed detection step (S300) are analyzed, and whether to control the RPM of the engine is determined according to the analysis result (whether the condition of the acquisition information is satisfied). .

In the determination step (S300), specifically, it is determined that engine RPM control is required when the auger 6 is rotating and a condition in which the current vehicle speed is equal to or greater than the set vehicle speed is satisfied.

Next, if it is determined that engine RPM control is required as a result of the determination through the determination step S300, the RPM control step S400 of forcibly lowering the engine RPM is performed thereafter. The control performed in the RPM control step S400 may preferably be a control to forcibly lower the current engine RPM to a set RPM to reduce the vehicle speed, and the set RPM may be, for example, an idle RPM. .

In the RPM control step S400, a control for forcibly lowering the engine RPM as described above may be performed together with a control to awaken the alertness through a warning means so that the driver recognizes that there is a danger situation and takes a quick follow-up action. For example, the driver can immediately recognize that a dangerous situation is through the alarm sound output control through the alarm sound output means or the warning message output control through the display device.

On the other hand, during engine RPM control through the RPM control step (S400), the time is counted from the point when the RPM control is executed, and the counted time exceeds the set time, or the auger operation is completed due to follow-up measures by the driver or completion of the auger operation. If the motion is not detected, a return control step (S500) of returning the engine RPM to the original RPM set by the accelerator lever may be further included.

According to the above embodiment of the present invention, the engine RPM of the combine is controlled in connection with the auger operation. Specifically, if the rotational motion of the auger is detected by the execution of the automatic return or automatic discharge function, and the current vehicle speed is higher than the set vehicle speed, the current engine RPM is forcibly lowered to the set RPM to reduce the vehicle speed, thereby minimizing the load on the auger. .

That is, by fundamentally preventing the aircraft from traveling at high speed while the automatic return or automatic evacuation function is running, the aircraft is turned to the left or right while driving at high speed or at high speed while the automatic return or automatic evacuation function is running. It is possible to reliably solve the problems of the prior art (damage or breakage of the auger driving device) caused by the steering operation to be performed.

According to the automatic return system of the combine auger of the combine according to the embodiment of the present invention, the control unit determines the control value of the auger motor for returning to the initial storage position by reflecting the inclined state of the aircraft, and the auger motor with the determined control value. By controlling the auger to return to the initial storage position, it is possible to always accurately return the auger to the same storage position regardless of the inclined state of the body.

That is, the auger return is automatically controlled by grasping the inclined state of the aircraft through the rolling sensor and calculating the auger motor control value for returning the auger initial storage position based on the determined information, even if the aircraft is located on an inclined or curved work surface. It is possible to accurately return the auger to a predetermined initial storage position, and thus damage to parts and safety accidents due to incorrect position control of the auger can be prevented.

In the above detailed description of the present invention, only specific embodiments according thereto have been described.
