DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine having a working unit and a traveling unit which can be moved relative to each other, and more specifically, a driving unit is integrated with a traveling device to maintain a good steering feeling. The present invention relates to a technique for improving the right and left weight balance while keeping the balance.

[0002]

2. Description of the Related Art Conventionally, a reaping unit can be moved to the left and right with respect to the machine body, and the reaping unit can be horizontally slid so that both a state suitable for middle cutting and a state suitable for rotation cutting can be obtained. Is known (Japanese Unexamined Patent Publication No.
No. 153841).

[0003]

In a combine, a threshing unit is usually located on the left side of the fuselage, and a grain storage unit such as a Glen tank or a bagging hopper is located on the right side. Since the grains that have been threshed are stored in the grain storage section, the right side of the aircraft gradually becomes heavier. Therefore,
Regardless of whether the reaping unit can be slid horizontally or not, when the kernels are full of kernels, the center of gravity is shifted to the right, and the right crawler sinks sharply in wetlands. It sometimes had a bad influence on running performance, such as difficulty in turning and difficulty running straight.

[0004] It is an object of the present invention to improve the maneuverability of a combine by preventing the left-right balance of the machine from changing as much as possible even when the load of the grain storage unit changes.

[0005]

[Means for Solving the Problems]

[Configuration] The first invention includes a crawler traveling device, a traveling unit including an operating unit, an engine, and a working unit including a cutting unit, a threshing unit, and a grain storage unit, which are arranged in the left-right direction of the machine body. With a relative movement mechanism capable of relative movement adjustment, comprising a kernel amount detection means capable of detecting the kernel amount stored in the kernel housing unit, as the kernel amount stored in the kernel housing unit increases, Slide control means for linking the grain amount detection means and the relative movement mechanism so as to move the working section to the side opposite to the grain storage section existence side with respect to the traveling section, and the slide control means operates Self
Motion control mode, and the running unit and the working unit
Mode switching to switch between manual operation mode and relative movement adjustment
Switching means for detecting whether the threshing unit is in a driving state.
Threshing detection means, and automatic control mode is selected.
When the threshing unit is being driven,
And the threshing unit is activated.
If not, the operation of the slide control means is disabled
As described above, slide control means, mode switching means and threshing detection
It is characterized in that the means and the means are linked .

[0006] A second invention is a crawler traveling device and an operation unit.
, A traveling section equipped with an engine, a reaping section, a threshing section, and a grain.
The work unit with the grain storage unit is
Equipped with a relative movement mechanism that can adjust the movement,
A means for detecting the amount of grains stored in the container
As the amount of grain stored in the grain container increases.
The working part is opposite to the running part from the side where the grain storage part exists.
So that the grain amount detection means and the relative movement mechanism
Slide control means for linking the
Automatic control mode with step operation and manual operation
Switch between the manual operation mode for adjusting the relative movement of the
Mode switching means to switch whether the aircraft is running
Is provided, and the manual control mode is selected.
When selected, the aircraft has stopped traveling.
So that the relative movement mechanism can be operated only when
Mode switching means, travel detection means, and relative movement mechanism
It is characterized by having.

According to a third aspect of the present invention, in the first aspect, a travel detecting means for detecting whether or not the aircraft is traveling is provided, and when the manual operation mode is selected, the aircraft stops traveling. The mode switching means, the travel detection means, and the relative movement mechanism are linked so that the relative movement mechanism can be operated only at the time.

According to the structure of the first aspect, the traveling unit including the crawler traveling device, the driving unit, and the engine, and the working unit including the cutting unit, the threshing unit, and the grain storage unit include: It is possible to adjust the relative movement in the left and right direction of the aircraft, so if the grain storage part becomes heavy and the left and right balance changes, it is possible to move the traveling part and the working part relatively sideways to absorb the balance change Yes, the left-right balance can be maintained in a predetermined state even if the amount of stored grains is different.

Since the driving unit is integral with the traveling unit, the positional relationship between the driving unit and the crawler does not change regardless of the lateral movement of the working unit. For example, when the working unit and the driving unit are integrated, the grain storage amount in the Glen tank increases during work traveling, and when the working unit moves to the left, the driving unit also moves to the left. May change and the illusion that the aircraft has shifted laterally from the strip, but in the case of the present application, the line of sight does not change even when the working unit moves laterally, so that the steering feeling can be maintained in a constant state. It is easy to drive. In addition, since the engine is also provided in the traveling section, there is no need to provide a structure capable of lateral movement in the transmission system between the engine and the crawler traveling device, so that a conventional simple structure can be used.

In addition, since there is provided a slide control means for moving the working unit with respect to the traveling unit to the side opposite to the side where the grain storage unit exists, as the amount of kernel stored in the kernel storage unit increases. The compensation function of the left and right balance by the relative lateral movement between the working unit and the traveling unit described above is automatically performed, and the load applied to the left and right traveling devices is equalized even during the cutting and threshing work, or the right side is slightly heavier. For example, the left and right balance can be automatically maintained in a predetermined state.

Further, according to the first aspect of the present invention, there is provided a mode switching means for switching between an automatic control mode in which the slide control means operates and a manual operation mode in which the relative movement between the traveling unit and the work unit is adjusted by manual operation. Therefore, in the case where the left-right balance is automatically compensated as described above, the mode switching means is switched to the automatic control mode. And, in order to correct that the right crawler's sinking is large due to the moving traveling place being muddy,
When the operator wants to move the work unit arbitrarily, for example, by moving the work unit to the left, the mode switching means may be switched to the manual operation mode, so that the user can properly use the work unit according to the purpose.

Further, according to the configuration of the first aspect, in the automatic control mode state, the slide control means can be operated when the threshing unit is driven, and when the threshing unit is not operated, the slide control means is not operated. Since the operation is disabled, the harvesting and threshing work and pillow handling work in the field, etc., are in a state where the grain is collected, that is, when the weight of the grain storage unit changes, work is performed accordingly. When the part moves sideways, such as turning on a headland or traveling, etc.,
When the weight of the grain container does not change, the working unit does not move laterally.

That is, when the working unit moves sideways during traveling at relatively high speed, the balance changes and it is difficult to operate, or the side plate of the threshing apparatus abnormally approaches the wall of the warehouse. Since it is more desirable, if the slide control means is operated only when the compensation of the right and left balance is truly required, it becomes easy to drive without unnecessary control operation.

According to a second or third aspect of the present invention, the airframe
Running detection means for detecting whether or not
When the pilot mode is selected, the aircraft
The relative movement mechanism can be operated only when the line is stopped.
Mode switching means, travel detection means and relative movement
According to the configuration linked with the mechanism , when the manual operation mode is selected, the relative movement mechanism can be operated only when the body is stopped traveling, so that the work during traveling or the like can be performed. When you do not need to move the part sideways,
Inadvertent lateral movement is eliminated, and the inconvenience that the working unit laterally moves unintentionally during traveling and the body sways left and right and it is difficult to drive is eliminated. The manual operation is performed when maintenance and inspection is performed, and when the left and right balance is determined according to the field conditions.

[Effect] In the combine according to any one of claims 1 to 3 , (a)
By moving the running unit and the working unit relative to each other with the driving unit and the engine integrated with the crawler running unit, the relationship between the running unit and the running location can be maintained constant without complicating the running transmission system. Thus, it is possible to provide a vehicle body moving device capable of correcting a change in the left-right balance caused by the weight of the grain storage unit becoming heavier as the work progresses while improving the running performance and the maneuverability.

Furthermore, in the combine according to any one of the first to third aspects, the automatic control mode state in which the above-mentioned effect (a) is obtained, and the manual operation in which the operator arbitrarily moves the working unit and the traveling unit laterally. You can select the mode and there is the convenience that you can use it properly according to the situation.

Further, in any of the combine according to any one of the first and second aspects, in the vehicle body moving device according to the first aspect, the slide control means based on the selection of the automatic control mode includes:
It was only activated when it was really needed, resulting in a sophisticated control state without waste of control or accidental movement.

In the vehicle body moving device according to the second and third aspects,
The relative lateral movement due to the selection of the manual operation mode is possible only when the aircraft is stopped, so that the ease of the lateral movement operation can be improved while preventing unexpected balance disturbance.

As shown in FIG. 1, FIG. 4, FIG. 5, and FIG. 7, the working section B mounts and supports a cutting section a, a threshing section b, a Glen tank 13, a fuel tank 26, and the like on a working frame 25. It is slidably supported in the left-right direction with respect to the traveling frame 27 by applying a rail structure. The rear hydraulic cylinder 23 is configured to penetrate both ends, and its pipe cylinder cylinder 23a is
7 is also used as a member connecting left and right, and both ends of the piston rod 23A are connected to left and right ends of the rear portion of the working frame 25. The front hydraulic cylinder 22 is also configured to have a short-length penetrating type at both ends. The cylinder cylinder 22a is fixed to the traveling frame 27, and both ends of the piston rod 22A are connected to left and right ends of a front portion of the working frame 25. .

As shown in FIG. 8, four rods 22A,
23A and the work frame 25 are connected via a rubber coupling F. The rubber coupling F includes a rubber portion 51 and mounting portions 50, 50 on both sides thereof. One mounting portion 50 is fixed to the ends of the rods 22A, 23A, and the other mounting portion 50 is fixed to the work frame 25, respectively. I do.

The piston rods 22A of each hydraulic cylinder,
23A connects the left and right end rods 22c, 23c for forming the oil chambers 22b, 23b with the connecting pipe 22.
It is formed in a long shape connected by d and 23d. In other words, the working frame 25 is configured to be slidable left and right within a predetermined range with respect to the traveling frame 27 by the left and right hydraulic cylinders 22 and 23 being driven to move left and right. The situation of the slide movement is as follows.

That is, the amount of leftward projection of the left side plate 28 of the threshing unit b from the left crawler 1L to the left is substantially equal to the amount of rightward projection of the right side plate 13a of the Glen tank 13 from the right crawler 1R. , A standard position where the working unit B projects left and right and laterally from the traveling unit A by a predetermined amount [see FIG.
From the standard position to the moving position (see FIG. 3 (b)) where the working unit B has moved most to the left side opposite to the grain storage unit existing side with respect to the traveling unit A (see FIG. 3 (b)). The relative position between the working unit B and the traveling unit A is moved by the relative moving mechanism 15 including the cylinders 22 and 23. The moving distance between the standard position and the moving position is determined by the hydraulic cylinders 22, 23.
Is the operation length.

As shown in FIGS. 5, 6, and 9 to 11, an engaging means H capable of restricting the relative movement between the traveling frame 27 and the working frame 25 is provided. Is set to a state in which the engaging means H operates when a predetermined relative set position is reached. The work frame 25 is mounted on a plurality of inclined rollers 52 mounted on the traveling frame 27, and has a structure in which the roller 52 relatively moves by rolling on the rolling surface 53 on the work frame side. And
At two positions, that is, the position where the Glen tank 13 moves to the rightmost position and the position to the leftmost position, the rolling surface 53 is formed with recessed portions 53a, 53a into which the rollers 52 enter. At both positions, even if the positioning function of the hydraulic cylinders 22 and 23 is incomplete due to leakage or the like, the relative displacement between the traveling portion a and the working portion b does not first occur due to the operation of the engagement means H.

In this combine, a control circuit is provided so that various controls for moving the relative movement mechanism 15 are performed. That is, the weight meter 41 is provided as a grain amount detecting means capable of detecting the amount of grain stored in the Glen tank 13,
A slide control means C for linking the weighing scale 41 and the relative movement mechanism 15 so that the working unit B moves to the left with respect to the traveling unit A as the amount of grains stored in the Glen tank 13 increases. The control device 37 is provided with mode switching means 39 for switching between an automatic control mode in which the control means C operates and a manual control mode in which the traveling unit A and the work unit B are relatively moved and adjusted by manual operation.

That is, as shown in FIG. 12, the electromagnetic control valves 38 of the front and rear hydraulic cylinders 22 and 23, the mode changeover switch 39, the left / right moving lever 40 for operating the electromagnetic control valve 38, and the lower part of the Glen tank 13 are provided. When the weight detected by the weighing scale 41 is the lightest (when there is no grain), the working unit B is in the standard position closest to the right, and the weighing scale 41 is connected to the control device 37. When the detected weight of 41 is the heaviest (when the grains are fully loaded), the function of the slide control means C is to automatically control the working unit B to the leftmost moving position. When the grain is fully loaded in the Glen tank 13 at the moving position, the weight balance in the left-right direction is set so that loads substantially equal to the left and right crawler traveling devices 1, 1 are applied. .

When the mode changeover switch 39 is switched to "automatic", the above-mentioned slide control means C is operated, and the working section B is automatically slid horizontally in accordance with the amount of collected grains in the Glen tank 13. The actual slide movement is performed when both the stock switch 46 and the direction switch 47 are turned off.
F, that is, when there is no transported culm in the vertical transport device 7 and there is no cereal culm to be harvested (for example, in the latter half of turning on a headland, at the time of joining, and when traveling between fields) Time).

However, when a clutch switch 45 (described later) for detecting that the threshing unit b is in the driven state is switched from OFF to ON, the slide control means C is activated, and the Glen tank at that time is activated. The working unit B slides laterally to a position corresponding to the storage amount of the 13th grain. Then, when the clutch switch 45 is switched from ON to OFF, the slide control means C does not operate, and, for example, the working unit B automatically returns to the standard position (storage posture) closest to the right. . Further, since the slide movement does not occur during the work traveling, even if the roll due to the lateral movement inertia occurs, there is no extra maneuvering operation such as performing steering correction for running straight, so that the driving becomes easy.

A stock switch 46 provided in the vertical transport device 7 and a direction switch which is a sensor for automatic steering control which is provided at the base of the weeding tool 48 and acts upon contact with the planted grain culm. 47 is a well-known one, and detailed description thereof is omitted.

When the mode is switched to "manual", the electromagnetic control valve 38 is operated by operating the left / right moving lever 40, and the working unit B can be arbitrarily moved laterally. As shown in FIG. 5, a stroke sensor 49 of a linear potentiometer type or the like for detecting the movement of the rear hydraulic cylinder 23 is provided so that the left and right positions of the working unit B with respect to the traveling unit A can be fed back. That is, the working unit B moves so as to follow the operation position of the left / right moving lever 40, and moves to the standard position when the left / right moving lever 40 is operated to the far right in FIG. It moves to the movement position.

By the way, the left and right moving lever 40 is of an on-off type in which the center is neutral and the working unit B moves to the left when tilted to the left and moves to the right when tilted to the right. By moving the relative movement mechanism 15 by tilting operation and then returning to the neutral position, the working unit B may be operated to an intended position.

For example, when the automatic control mode is selected, the working unit B is shifted to the right before the start of the mowing and threshing work, but the narrow space with the overhanging projection is used. When passing, it is conceivable that the mode changeover switch 39 is set to "manual" so that the working unit B is moved to the left to allow the passage.

Further, this combine has threshing detecting means 42 for detecting whether or not the threshing unit b is in a driving state, and when the automatic control mode is selected,
When the threshing unit b is driven, the slide control unit C is operable, and when the threshing unit b is not operating, the operation of the slide control unit C is disabled. The threshing control means D for linking the switch 39 and the threshing detection means 42 with the control device 37
It is prepared for.

More specifically, a threshing detecting means 42 is constituted by a threshing clutch lever 44 for turning on and off a threshing clutch (not shown) and a clutch switch 45 which is activated when the lever position is turned on. Is switched to "automatic", the slide control means C is controlled so as to operate when the clutch switch 45 is "on" and not to operate when the clutch switch 45 is "off". It is.

In addition, a travel detecting means 43 for detecting whether or not the aircraft is traveling is provided. When the manual operation mode is selected, the relative movement mechanism is provided only when the aircraft is not traveling. The control device 37 is provided with travel control means E for linking the mode changeover switch 39, the travel detection means 43, and the relative movement mechanism 5 so that the control unit 15 can operate.

That is, when the speedometer 54 as the travel detecting means 43 is connected to the control device 37 and the mode changeover switch 39 is switched to "manual", the speed detected by the speedometer 54 becomes zero (or When the speed is lower than or equal to an extremely low speed, the manual operation of laterally moving the working unit B using the left / right moving lever 40 is possible. However, when the detection speed of the speedometer 54 is not zero (or when the speed is higher than the extremely low speed). Even if the left / right moving lever 40 is operated by locking the electromagnetic control valve 38 to the neutral position, the relative moving mechanism 15
Is controlled not to move.
