Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a traveling main transmission and a traveling auxiliary transmission for shifting the output from the traveling main transmission, and a conveying device for conveying a harvested grain culm to a threshing device. The rotational speed of the rotating body that is driven by the output of the device, is provided so that the traveling device is driven by the output of the traveling auxiliary transmission, and is driven and rotated by the output of the traveling auxiliary transmission. Control of a combine provided with a rotation speed detecting means for detecting a vehicle speed or a traveling distance, and a calculating means for obtaining a transfer speed or a transfer distance in the transfer device based on the rotation speed information of the rotation speed detecting means. The present invention relates to an information detection device.

[0002]

2. Description of the Related Art The combine control information detecting device is
For example, vehicle speed information necessary for traveling control for stable traveling of the combine, conveying distance information of the cutting culms necessary for handling depth control for appropriately controlling the handling depth state in the threshing device, and the like. , Or the speed information of the cut culms necessary for threshing control, etc. to control the handling capacity and the sorting capacity to a proper state in response to the fluctuation of the grain culm supply amount to the threshing device (this is the grain culm supply amount. (Corresponding to), etc., and the control information necessary for various controls of the combine is detected.

In the prior art, based on the rotational speed information of the rotating body driven and rotated by the output of the traveling auxiliary transmission that drives a traveling device such as a crawler traveling device, specifically,
The vehicle speed or mileage is detected by counting the number of revolutions within a predetermined time to obtain the vehicle speed, or by accumulating the number of revolutions when traveling from one point to another to obtain the mileage. At the same time, with respect to the conveying speed or the conveying distance in the conveying device driven by the output of the traveling main transmission located on the transmission side of the traveling auxiliary transmission, the auxiliary transmission position of the traveling auxiliary transmission is the standard shift position. In the position (for example, the medium speed position when the sub-shift is the third gear), the detection is performed based on the rotation speed information of the rotating body under the condition that the normal transport speed or the transport distance is obtained.

[0004]

Therefore, in the above-mentioned prior art, the vehicle speed or the traveling distance can be detected as a proper value regardless of the auxiliary shift position of the traveling auxiliary transmission, but the conveying speed or the traveling distance can be detected. , A value other than the standard shift position is detected as a value greater than the normal value when the auxiliary shift device is in a position other than the standard shift position, for example, a higher speed shift position, while it is a lower shift position than the standard shift position. There is a problem that the value is detected as a value smaller than the normal value, and the detection error becomes large at shift positions other than the standard shift position.

Therefore, for example, in the control of the depth of handling, usually, at the start of the mowing operation, the conveying grain culm is detected by the grain culm presence / absence detecting means, and then the conveying distance of the grain culm is determined by the presence or absence of the grain culm. Detection point of the tip position detecting means is set so that the handling depth control operation is started as the set distance corresponding to the conveying path from the position of the detecting means to the position of the tip position detecting means on the lower side of the conveyance is reached. The inconvenience when the handling depth is adjusted when the grain culm has not reached the position is avoided, but for example, when the sub-shift position is shifted to the slow fall position, the transport distance is Since it is detected as a value smaller than the value, the handling depth control operation is not started and the activation is delayed even though the culm is actually conveyed to the installation location of the tip position detecting means. There was. In that case, proper handling depth adjustment is not performed for the grain culms transported until the detected transport distance reaches the set distance and the handling depth control operation starts. As
When the handling depth state before the handling depth control operation starts is stopped in a state where the handling depth is adjusted to the deep handling side and a long grain culm is transported, it becomes an extremely deep handling state. There was also a risk that the grain culms would be clogged in the threshing device.

Therefore, in order to solve the above problems, the rotating body is driven and rotated by the output of the traveling main transmission, and the conveying speed or the conveying distance is determined by the auxiliary shift of the traveling auxiliary transmission. While making it possible to detect a normal value regardless of the position, regarding the vehicle speed or mileage,
It is conceivable to detect the auxiliary shift position of the traveling auxiliary transmission and perform a correction process according to the position to obtain a normal value. For example, the traveling auxiliary transmission may be a gear mesh type. In this case, the rotating body is driven by the output of the traveling main transmission even though the transmission of power to the traveling device is cut off during the shifting operation. The vehicle speed or mileage may be erroneously detected to be larger than the regular value.

As another means, another rotating body driven and rotated by the output of the main transmission for traveling is provided, and the conveying speed or the conveying distance is based on the rotational speed information of the rotating body. However, in this case, two detection systems for detecting the rotating body and the number of rotations thereof, one for detecting the vehicle speed or mileage and the other for detecting the transport speed or the transport distance, are required, and the device configuration is It has the drawback of being complicated and expensive.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a rotating body and a rotating speed detecting means for detecting rotating speed information by one in order to solve the problems of the above-mentioned prior art. After all, in the configuration in which the device configuration is simplified and the normal value of the vehicle speed or the travel distance can be detected, the detection error of the transport speed or the transport distance is minimized.

[0009]

The combine control information detecting device according to the present invention is characterized in that an auxiliary shift position detecting means for detecting an auxiliary shift position of the traveling auxiliary transmission device is provided, and the computing means is It is configured such that the transport speed or the transport distance is obtained based on the detection information of the auxiliary shift position detection means and the rotation speed information of the rotation speed detection means.

[0010]

According to the characterizing feature of the present invention, in order to obtain the conveying speed, for example, the traveling auxiliary transmission has three modes of high speed, medium speed and low speed.
A sub-shift position detection in which the regular conveying speed is detected by counting the number of rotations of the rotation number detecting means within a predetermined time when the gear is shifted to the middle speed position If the auxiliary gear shift position detected by the means is a high-speed traveling gear shift position, the detected conveyance speed is a value larger than the normal speed, so the correction processing (small ) To obtain a normal transport speed, and if the auxiliary shift position is a medium speed standard shift position, the detected transport speed is directly obtained as the transport speed, and if the auxiliary shift position is a low speed shift position. Since the detected transport speed is a value smaller than the regular speed,
The correction speed is increased (increased) with a coefficient determined by the speed ratio of the traveling auxiliary speed change device to obtain the normal transport speed.

Similarly, in order to obtain the transport distance, for example, when the traveling auxiliary transmission is shifted to the medium speed position among the above three stages, the rotation speed of the rotation speed detecting means is integrated to carry out the normal transport. In the case where the distance is detected, if the auxiliary gear shift position detected by the auxiliary gear shift position detecting means is a high speed traveling gear shift position, the detected transport distance is a value larger than the regular distance, so Correcting (decreasing) a coefficient determined by the gear ratio of the sub transmission to obtain a normal transport distance, and if the sub shift position is a medium-speed standard shift position, the detected transport distance is directly obtained as the transport distance. ,
If the auxiliary shift position is the low-speed fall shift position, the detected transport distance is a value smaller than the normal distance, so correction processing (larger) is performed with a coefficient determined by the gear ratio of the traveling auxiliary transmission. Try to find the regular transport distance.

According to the configuration of the present invention, for example, when the traveling auxiliary transmission is of the gear mesh type, it is driven by the output of the traveling auxiliary transmission during the auxiliary transmission operation. Since the rotating body is not driven to rotate, the detection value of the transport speed or transport distance may be smaller than the normal value, but the information required for the transport speed or transport distance may be smaller than the vehicle speed or travel distance. The accuracy is not so high, so it is not a big problem in practice.

[0013]

Therefore, according to the characteristic construction of the present invention, the combine speed of the vehicle or the traveling distance can be accurately detected by the simple apparatus construction, and the detection error of the conveying speed or the traveling distance is minimized. The control information detecting device can be obtained.

In the figure, S0 is a stock origin sensor for contacting the stock of the cut grain culm at the carrying start end of the vertical carrying device 8 to detect the presence or absence of the culm carried by the vertical carrying device 8. is there. To add an explanation, the cutting culm will contact the stock sensor S0 and the stock sensor S0 will be kept ON during the cutting operation, and the supply of the cutting culm will be interrupted when the cutting work is finished. Therefore, the grain culm does not contact the stock origin sensor S0 and the stock origin sensor S0 is turned off. Therefore, the stock origin sensor S0 corresponds to a grain culm presence / absence detecting means for detecting the presence / absence of a transported grain culm.

As shown in FIGS. 1 and 4, the vertical conveying device 8 holds a conveying device 8A for holding and conveying the plant side of the cut grain culm, and a lock for locking and conveying the tip end side of the cut grain culm. Consists of a conveying device 8B and a grain culm guide plate 8C, conveys the cut grain culm from the auxiliary conveying device 6 in a vertical posture toward the rear of the machine body, and changes the posture to a horizontal posture at the conveying end portion to perform threshing. It is configured to be delivered to the feed chain 7.

Further, the vertical transfer device 8 is pivotally mounted at a terminal end portion thereof about a horizontal axis P so as to be vertically swingable, and the cut grain supplied from the auxiliary transfer device 6 in association with the vertical swing. The support position of the culm is changed to the culm direction, and further, the position of the cut grain culm transferred from the vertical transfer device 8 to the threshing feed chain 7 is changed to the culm direction, and the handling depth in the threshing device 2 is increased. It is configured to be modified and adjusted.

The rocking operation structure of the vertical transfer device 8 will be described. As shown in FIG. 1, an electric motor M as an actuator for adjusting the handling depth is provided, and can be rocked around a horizontal axis Q. A rack 11 is attached to the arm 14, and the pinion 12 that engages with the rack 11 is the electric motor M.
It is attached to the rotating shaft of. In addition, the inverted U-shaped member 13 and the arm 14 which also serve as the frame of the vertical transfer device 8 are provided.
And are interlockingly connected via the push-pull rod 15, and by operating the electric motor M forward and reverse,
The vertical transport device 8 is adapted to swing up and down. Therefore, the vertical transport device 8, the push / pull rod 15, the arm 14,
The electric motor M or the like constitutes the handling depth adjusting means C for adjusting the handling depth in the threshing device 2.

As shown in FIGS. 1 and 4, a pair of tip ends as a pair of tip position detecting means for detecting the tip position of the grain culm in the conveying route of the conveyed grain culm conveyed by the vertical conveying device 8. The sensors S1 and S2 are provided at intervals in the culm direction of the grain culm, and the pair of tip sensors S1 and S2 are provided.
Is set so that it is on the lower side in the grain culm transport direction than the handling depth adjustment location by the handling depth adjusting means C and the installation location of the stock origin sensor S0. Each of the pair of tip sensors S1 and S2 reciprocally swings toward the lower side of the conveyance due to contact with the grain stem, and the sensor lever 16 biased to return to the upper side in the conveying direction, and the backward swing of the sensor lever 16. And a switch-use detection unit 17 for detecting That is, if the sensor lever 16 moves backward and swings due to the contact with the grain culm and the detecting unit 17 is turned ON, the presence of the grain culm is detected, and if the detecting unit 17 is OFF, the absence of the grain culm is detected.

Next, the power transmission system of the combine will be described. As shown in FIG. 2, the output of the engine E is transmitted to the threshing device 2 via the belt tension type threshing clutch 10 and the belt transmission is performed. It is transmitted via a mechanism to a hydraulic continuously variable transmission 9 as a main transmission for traveling. Reference numeral 20 denotes a threshing clutch lever for manually turning on and off the threshing clutch 10. The output of the continuously variable transmission 9 after shifting is transmitted to the transmission case 18 and is shifted by the traveling auxiliary transmission D (see FIG. 3) in the mission unit 18, and the output of the traveling auxiliary transmission D is transmitted. The pair of left and right crawler traveling devices 1 are driven by the one-way clutch, and the output of the continuously variable transmission 9 after shifting is a one-way clutch so that the reaper B is driven only when the vehicle is moving forward. It is configured to be also transmitted to the mowing section B via 21 to drive each part of the mowing section B. As a result, the vertical conveyor 8 is driven by the output of the continuously variable transmission 9, and the grain culm conveying speed is changed and adjusted according to the output.

In the traveling auxiliary transmission device D, the auxiliary transmission lever 25, which can be swung in the front-rear direction, is used to shift the vehicle to a high-speed traveling shift position which is the front position of the swing and a medium speed which is the central position of the swing. The auxiliary shift lever 25 is operated to a high-speed traveling shift position by operating the standard shift position and the low-speed fall shift position, which is the front side position of the swing, to shift in three steps. There is provided a first limit switch SW1 which is turned on when the auxiliary shift gear 25 is turned on and a second limit switch SW2 which is turned on when the auxiliary shift lever 25 is operated to a low-speed fall shift position. Therefore, when the first limit switch SW1 is in the ON state, the second limit switch S
If W2 is in the OFF state, it means that the vehicle is in the high-speed traveling shift position,
If both limit switches SW1 and SW2 are in the OFF state, it is the standard shift position of medium speed, and the first limit switch SW1 is in the OFF state and the second limit switch SW2 is in the O state.
In the N state, it is detected that the vehicle is in the low-speed fall shift position. Therefore, the limit switches SW1 and SW2 constitute an auxiliary shift position detecting means for detecting the auxiliary shift position of the traveling auxiliary transmission device D. become.

Explaining the main part of the mission case 18, as shown in FIG. 3, the power from the output shaft 30 of the continuously variable transmission 9 is the first in the mission case 18.
The power from the first transmission shaft 31 is transmitted to the reaper B via the transmission shaft 31, and the power from the first transmission shaft 31 is transmitted to the first gear 32 and the second gear 32.
It is transmitted to the second transmission shaft 34 via the gear 33. A shift gear 35 is slidably fitted to the second transmission shaft 34 by a spline structure, while a high speed gear 37, a medium speed gear 38 and a low speed gear 3 are attached to the third transmission shaft 36.
9 is fixed. Then, the shift gear 35 is slid so that the second high speed gear 41 is engaged with the high speed gear 37, or the shift gear 35 is switched to the middle speed gear 38 or the low speed gear 39 to be engaged with each other.
The forward drive power for straight traveling transmitted to the third transmission shaft 36 is transmitted to the pair of left and right crawler traveling devices 1 after shifting to high, medium and low three stages. With the above-described structure, the traveling auxiliary transmission device D, which changes the output from the continuously variable transmission device 9 as the traveling main transmission device, includes the shift gear 35 and the high-speed gear 3.
7, a medium speed gear 38, a low speed gear 39 and the like.

The transmission mechanism from the third transmission shaft 36 to the pair of left and right crawler traveling devices 1 will not be described in detail, but in the middle thereof, the left and right crawler traveling devices 1 for turning the machine body are respectively provided. A pair of left and right traveling clutches are provided for operating the power separately. Further, the rotating body 40 is attached to the third transmission shaft 36,
A rotation speed sensor S3 that detects the rotation speed of the rotating body 40 is provided. Then, the number of pulses output according to the number of revolutions of the rotating body 40 within a predetermined time is counted to calculate the vehicle speed, or is output while traveling from one point to another point. Since the traveling distance can be detected by integrating the number of pulses, the rotation speed sensor S
3 corresponds to a rotation speed detecting means for detecting a vehicle speed or a traveling distance, which detects the rotation speed of the rotating body 40 driven and rotated by the output of the traveling auxiliary transmission device D. However,
As described above, the reaper B has the one-way clutch 21.
Since it is driven only when the machine body moves forward via the, the vertical conveyance device 8 is stopped when the machine body moves backward. Therefore, the vehicle speed or the traveling distance is measured by the rotation speed sensor S3 only when the vehicle is moving forward, and is stopped when the vehicle is moving backward.

As shown in FIG. 1, a control device H using a microcomputer is provided.
, The stock sensor S0, the pair of tip sensors S1,
Each signal from S2, the rotation speed sensor S3, the first limit switch SW1 and the second limit switch SW2 is input, and the threshing switch 19 and the handling depth that are turned on in response to the operation of entering the threshing clutch lever 20. A signal from the control start command switch 22 is input. Further, the control device H outputs drive signals to the drive circuit 18 of the electric motor M and the alarm device 24. The alarm device 24 is provided in the driver's seat 3
It consists of a buzzer and a flashing lamp provided in the.

Utilizing the control device H, the first limit switch SW1 and the second limit switch SW1 serving as the auxiliary shift position detecting means.
An arithmetic unit 100 is configured to obtain the transport distance of the grain stems in the transport device 8 based on the detection information of the limit switch SW2 and the rotation speed information of the rotation speed sensor S3.

Then, the control device H detects the presence of the grain stem by the stock origin sensor S0 based on the information of the pair of tip sensors S1 and S2, the stock origin sensor S0 and the computing means 100. As the conveying distance calculated by the computing means 100 reaches the set distance, only the one S2 of the pair of tip sensors S1 and S2 on the plant side detects the handling depth in order to maintain the state of detecting the presence of grain culm. The depth control means for starting the handling depth control operation for activating the height adjusting means C, and the handling depth control is performed as the calculated transport distance reaches the set distance after the stock origin sensor S0 detects the absence of grain culm. It is configured to stop operation. In the handling depth control operation, a drive signal is output to the electric motor M to swing the vertical transport device 8 up and down. If the vertical transport device 8 swings downward, the vertical transport device 8 is adjusted to the deep handling side and moved upward. If you swing to, it will be adjusted to the shallow handling side.

Next, the structure of the control device H will be described in detail while explaining the control operation of the control device H based on the flow charts shown in FIGS. The state where the handle depth control start command switch 22 is in the ON state and the threshing clutch lever 20 is turned on and the threshing switch 19 is in the ON state is set to the state where the control condition is satisfied. Check whether the control conditions are met. When it is confirmed that the control conditions are satisfied, the transport distance calculation process (FIG. 7) is performed. In the process of calculating the transport distance, the output pulses of the rotation speed sensor S3 are integrated and the integrated pulse number is multiplied by a predetermined conversion coefficient to detect the transport distance.
Next, the auxiliary shift position is detected by both of the limit switches SW1 and SW2, and if it is a traveling shift position, the detected transport distance is divided by a coefficient α1 (α1> 1) to obtain a calculated transport distance, which is the standard shift position. For example, the detected transport distance is directly used as the calculated transport distance, and if it is the fall shift position, the detected transport distance is divided by a coefficient α2 (α2 <1) to obtain the calculated transport distance. That is, since the transport distance obtained by multiplying the integrated output pulse number from the rotation speed sensor S3 by the conversion coefficient is a regular transport distance at the standard shift position, it is detected at the traveling shift position. On the other hand, the conveyance distance becomes larger than the actual value, but the detected conveyance distance becomes smaller than the actual value at the fall shift position, it is necessary to correct it. Incidentally, the coefficients α1 and α2 correspond to the gear ratios of the auxiliary transmission device D at the traveling gear shift position and the fall gear shift position, respectively, where the gear ratio at the standard gear shift position is 1.

After the transport distance is calculated, the state of the stock origin sensor S0 is checked. If the stock distance sensor S0 is in the ON state, it is determined that the harvesting operation is being performed, and the stock origin sensor S0 is turned off.
Set distance after changing from the ON state to the ON state (This set distance is
Whether the grain culm is set to the transportation distance when it is transported from the installation location of the stock origin sensor S0 to the installation location of the pair of tip sensors S1 and S2), that is, from the OFF state of the stock origin sensor S0 It is checked whether or not the calculated transport distance has reached the set distance, starting from the time point when the ON state is changed. And only when the above set distance is reached,
Set the control activation flag for depth control.

On the other hand, in the above, when the stock origin sensor S0 is in the OFF state, it is judged that the mowing work has been completed. However, even if the stock origin sensor S0 is turned off, the grain culm which is being conveyed by the vertical conveyor 8 Is the pair of tip sensors S1 and S2
In order to maintain the control state until it is transported to the installation location, whether or not the stock sensor S0 has been transported by the set distance after being changed from the ON state to the OFF state, that is, the stock sensor S0 is switched from the ON state to the OFF state. It is checked whether or not the calculated transport distance has reached the set distance by using the changed time as a starting point. Then, only when the set distance is reached, the control activation flag is cleared. Then, according to the state of the flag, if the flag is set, the handling depth control is executed, while if it is cleared, the handling depth control is not executed.

The handling depth control will be described with reference to the flow chart shown in FIG. 8. In the case where the lower tip sensor S2 on the root side is in the ON state and the upper tip sensor S2 on the tip side is in the OFF state. Since the handling depth is appropriate, the handling depth adjustment is stopped after the elapse of a predetermined delay time to maintain the handling depth state. Also, the lower tip sensor S on the stock side
2 is in the ON state, and when the upper tip sensor S2 on the tip side is in the ON state, it is located on the deep handling side,
After the lapse of the delay time, the handling depth is adjusted to the shallow handling side. In addition, the above-mentioned delay time is the tip sensors S1 and S2.
In order to prevent the handling depth adjustment operation from becoming unstable (hunting) by repeating ON / OFF operation within a short time, the tip position of the grain stem is a predetermined distance from the detection position of the tip sensors S1 and S2. Although they are located apart from each other, the delay time is sufficiently shorter than the transport time required to transport the set distance.

On the other hand, when the lower tip sensor S2 on the root side of the pair of tip sensors S1 and S2 is in the OFF state and the upper tip sensor S1 on the tip side is in the OFF state, it is located on the shallow handling side. Therefore, after the delay time has elapsed, the depth of handle adjustment is adjusted to the deeper side, but the lower tip sensor S2 on the plant side is in the OFF state, and the upper tip sensor S2 on the tip side is in the ON state. In some cases, it is determined that foreign matter such as floating straw is clogged, the control operation is immediately stopped, and the alarm device 24 is activated to notify that floating straw or the like is occurring.

[Other Embodiments] In the above embodiment, the cumulative pulse number from the rotation speed detecting means S3 is multiplied by a predetermined conversion coefficient to detect the conveying distance which is a normal value when the auxiliary shift position is the standard shift position. However, when the auxiliary shift position is the traveling position or the fall position, the detected conveyance distance is calculated by the coefficient α1.
Alternatively, the correction processing is performed by dividing by the coefficient α2 (as it is when the sub-shift position is the standard shift position) to calculate the correct transport distance. Alternatively, the number of pulses may be subjected to the correction process, and the integrated pulse number after the correction process may be multiplied by the conversion coefficient to obtain the transport distance. It can be changed appropriately.

Further, in the above embodiment, the calculation means 100 calculates the conveying distance of the grain culm in the conveying device 8 based on the rotation number information of the rotation number detecting means S3, but the conveying speed is used instead of the conveying distance. You can also ask. A flowchart of the control operation in this case is shown in FIG.
First, the rotation speed detection means S within a predetermined time is shown in FIG.
The output pulse from 3 is counted to detect the transport speed. However, since the detected transport speed is a transport speed that becomes a normal value when the sub-shift position is the standard shift position, when the sub-shift position is the traveling position or the fall position, the detected transport speed is detected. Is the coefficient α1 or the coefficient α2
The correct transport speed is calculated by dividing by and correcting (as it is when the auxiliary shift position is the standard shift position). Then, although not described in detail, since the larger the grain culm is transported and supplied to the threshing device as the above-mentioned transport speed is higher,
This transportation speed information can be used as control information of the handling capacity of the threshing device or control information of the sorting capacity of the sorting device in association with the information of the grain culm supply amount.

In the above embodiment, the traveling main transmission 9 is used.
Although it is constituted by a hydraulic continuously variable transmission, it is not necessary to be limited to the hydraulic type, and the number of gears may be a predetermined number instead of continuously. In addition, the traveling auxiliary transmission D also has high, medium, low 3
Although the number of stages is set, the number is not limited to this and may be two stages.

Further, in the above embodiment, the traveling auxiliary transmission D
Auxiliary shift position detecting means SW1, S for detecting the auxiliary shift position of
Although W2 is composed of a limit switch that is turned on by the swinging operation position of the auxiliary transmission lever 25, a photoelectric sensor or the like that detects in a non-contact manner may be used instead of the limit switch. Further, the number of installation locations and the number of installations are not limited to ones (two in total) provided at the traveling shift position and the falling shift position.

In the above embodiment, the pair of tip position detecting means S1 and S2 detect the grain culm of the threshing device 2 in the vertical posture at the vertical conveying device 8 which conveys the culm. The grain culm may be detected in a horizontal posture on a placement guide plate or the like that receives and guides the grain culm tip side portion toward the receiving port. Further, the pair of tip position detecting means S1 and S2 and the grain culm presence / absence detecting means S0 are constituted by switches for detecting in a contact type, but a photoelectric sensor or the like for detecting in a non-contact manner may be used.

Further, in the above embodiment, the handling depth adjusting means C
Although the vertical conveying device 8 is vertically swung to adjust the handling depth, the present invention is not limited to this, and the feed chain 7 may be moved in parallel to the threshing device 2, for example.
