DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a grain discharging auger device in a combine.

[0002]

2. Description of the Related Art There is a combiner provided with a horizontal auger for discharging paddy, which can be moved up and down and turned by power, at the upper part of a fuselage.

[0003] At this time, the raising and lowering or turning operation of the horizontal auger, or the paddy discharging operation through the horizontal auger,
It is designed to be operated by operating operating means such as switches and levers provided in the control unit.For example, when paddy is padded by a single person, the lateral auger is placed near the tip of the lateral auger. Need to be activated.

In order to meet this need, a switch for raising / lowering or turning the horizontal auger is provided at the tip of the horizontal auger (see Japanese Patent Publication No. 6-42807).

[0005] In this case, the operating means issues a command to move the lateral auger up and down and turn by power.

[0006]

In the above-mentioned combine, turning by the power of the lateral auger not only tends to cause an unsafe condition, makes it difficult to finely adjust the turning position, but also complicates the control structure.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a grain discharging auger device in a combine which can turn a lateral auger from the tip thereof by artificial force.

[0008]

In order to achieve the above object, according to the present invention, a cutting section, a control section, an engine, a threshing and sorting section, and a grain tank are supported by a traveling section, and the machine body is provided at a specific location of the machine body. In a combine that has a horizontal auger for grain discharge that is capable of raising and lowering and turning by power at the top, no brake means is provided at the tip of the horizontal auger to restrict the turning of this auger as necessary. A turning restriction release switch for setting the state is provided.

In the present invention, when the lateral auger is not turned by the power, the brake means acts to restrict the turning of the lateral auger. Then, the brake means is in the non-regulated state, and the lateral auger is in a state in which the lateral auger is displaced by the operation force of the operator near the distal end thereof. Conversely, when the turning release switch is operated, for example, to the on state, the brake means is in the restricted state, and the lateral auger is in a state in which the turning is prevented.

The above-described invention is specifically as follows. That is, when the turning means is turned on by the operation of the turning restriction release switch, the turning operation by the power of the lateral auger is not performed when the brake means is set to the non-restricted state. With this configuration, when the operator turns the sideways auger by hand, the sideways auger does not forcibly turn with power, and the safety of work is ensured.

The brake means is incorporated in the electric motor for turning the lateral auger, and when the power supply to the electric motor is cut off by the operation of the turning restriction release switch, a non-regulated state is set. In this case, the brake means and the electric motor need only have the conventional structure, and the new part has a simple structure.

A handle for applying artificial force to rotate the auger is provided at the tip of the lateral auger. Thereby, the turning operation of the lateral auger by the operator can be conveniently performed.

The turning restriction release switch is operated by the gripping operation of the handle so as to bring the flake means into the non-restricting state. This eliminates the need to perform the operation of operating the turning restriction release switch separately from the gripping operation of the handle.

3 is input. In FIG. 4, 35
Is a battery, 36 is a relay box for starting and stopping the electric motor, 37 is a relay box for starting and stopping the electric motor, and 38 is a switching operation of an oil direction switching valve for supplying and discharging pressure oil for expanding and contracting the hydraulic cylinder. It is a solenoid to make it.

The operating device is used, for example, as follows. That is, when there is no problem even if the paddy discharging auger device 8 is operated from the control unit 4, the required operation is performed by operating the operation means 24A of the control unit 4.

For example, when it is desired to raise the lateral auger 12, the lever member of the cross lever switch 25 is rocked backward, and when it is desired to lower the lever, the control device 23 causes the solenoid to operate. The hydraulic cylinder 17 is extended or lowered in relation to the operation through the operation, and the operation of the hydraulic cylinder 17 causes the lateral auger 12 to swing about the X axis, and raises or lowers the paddy discharge port 20.

When it is desired to turn the lateral auger 12 to the left, the lever member is swung to the left, and when it is desired to turn to the right, it is swung to the right. The control device 23 energizes the electric motor 16, sets the brake means 16a in an unregulated state, and rotates the brake means 16a forward or backward in response to the operation. This rotation rotates the vertical pipe 15 around the Y axis, and The auger 12 is turned leftward or rightward.

After moving the horizontal auger up and down and turning it to the required position as described above, one switch s1 of the paddy discharge switch 30 is turned on. As a result, the control device 23 activates the electric motor 26 of the clutch mechanism 14, whereby the clutch mechanism 14 is brought into the engaged state, and the rotation of the engine 13 is controlled by the lower conveyor 9.
Is transmitted to The rotation of the lower conveyor 9 is transmitted to the vertical conveyor 10a, the succession conveyor, the original conveyor 18b, and the destination conveyor 19b in this order, and the paddy in the paddy tank 7 is discharged from the paddy discharge port 20.

When the discharge of paddy is stopped, the other switch s2 is turned on and operated.
3 operates the electric motor 26 in the reverse direction, and by this operation, the clutch mechanism 17 is disengaged and the engine 13
Is separated from the lower conveyor 9 and the discharge of paddy is stopped.

In some cases, the paddy discharged from the paddy discharge port 20 may be sequentially stored in another bag. In such a case, the operating means 24B at the tip of the lateral auger 12 must be operated. Causes the lateral auger 12 to operate.

That is, for example, when it is desired to raise the horizontal auger 12, one of the elevation switches 28 is pushed and the switch 28a is pressed.
Reference numeral 3 indicates that the hydraulic cylinder 17 is extended during the pushing operation of the switch 28a, and this operation causes the lateral auger 12 to swing upward around the X axis and raise the paddy discharge port 20.

On the other hand, when it is desired to lower the lateral auger 12, the other switch 28b is pushed, and the control device 23 thereby operates the switch 28b during the pushing operation.
The hydraulic cylinder 17 is shortened, and this operation swings the lateral auger 12 downward around the X axis, and lowers the paddy discharge port 20.

To turn the lateral auger 12, the grip 33 a of the handle 33 is gripped together with the lever member 34. At this time, since the lever member 34 is displaced toward the grip portion 33a by the hand gripping the handle 33, the electric motor 1
6 is cut off, so that the electric motor 16 does not rotate even if the cross lever switch 25 is erroneously operated, and the brake means 16
a is in an unregulated state, and the lateral auger 12 can be turned left and right by artificial force.

In particular, when packing paddy in a paddy, it is necessary to align the outlet 20 of the paddy accurately with the mouth of the bag.
Since the turning position of the lateral auger 12 can be finely adjusted accurately with its own hands without leaving the paddy discharge port 2
0 is simply matched to the mouth of the bag.

With the horizontal auger 12 set at a required position by the raising and lowering and turning operations of the horizontal auger 12, one of the switches s1 of the paddy discharge switch 31 is set.
To operate. As a result, similarly to the case of operating the paddy discharge switch 27 of the control unit 4, the control device 23 operates the electric motor 26 of the clutch mechanism 14, and in this connection, the paddy in the paddy tank 7 Will be discharged from When the other switch s2 is turned on, the discharge of the paddy is stopped as in the case of the operation of the pad discharge switch 27 of the control unit 4.

[0040]

According to the present invention configured as described above,
The operator at the tip of the sideways auger can easily turn this auger with artificial power during the grain discharging work,
In addition, since it is manually operated, fine adjustment of the turning position of the lateral auger can be performed accurately, which is particularly useful in a single operation when bagging grains.

In addition, the turning of the lateral auger by artificial force is safer than the case of power, and the operation of the electric motor is irrelevant in the turning operation from the tip of the lateral auger, so that the electric circuit structure is simplified. .

According to the second aspect, when the lateral auger is turned by an artificial force, the lateral auger is prevented from being erroneously turned by the power, and safety during the turning operation is ensured.

According to the third aspect of the present invention, since the conventional brake means 16a and electric motor 16 are sufficient, a new structure required for raising and lowering and turning the lateral auger can be simplified. The electric circuit is simplified because the brake means is set in the non-regulated state by cutting off the power supply to the motor.

According to the fourth aspect, the lateral auger can be easily swiveled with a relatively small force, and according to the fifth aspect, the lateral auger can be easily swiveled with one hand. Become.

3 is connected to a harness h1 extending from the connector 3 via a pair of connector portions c1 and c2.

Another harness h2 having a function equivalent to the function of the harness h1 is extended to the vicinity of the vertical auger 10. In the middle of the harness h2, a speed reduction circuit (not shown) for slowing down the rotation of the electric motor 16 is provided, and the distal end of the harness h2 is located at the base end of the cord 41 wound by the cord reel 40 mounted on the body. Connected.

At the end of the cord 41, a connector portion c3 for detachably connecting a connector portion c2 of the operation panel CB separated from the harness h1 of the control section 4 is attached. Code 41 is the horizontal auger 1
The length is not longer than the length 2, and is wound around the cord reel 40 by a spring force. The operating means 24B at the tip of the lateral auger 12 in the previous embodiment is not provided. The other parts are the same as in the previous embodiment.

The operating device of the paddy discharging auger device 12 according to this example is used, for example, as follows. That is, the control unit 4
When the paddy discharge auger device 12 is operated from the operation panel 2, the operation panel CB is set in the control section 4 and the operation means 2
4A cross lever switch 25 and paddy discharge switch 27
Operates as described in the previous example.

On the other hand, when operating the paddy discharging auger device 12 from a place other than the control section 4, the harness h of the control section 4 is required.
The control panel CB is detached from the fuselage by separating the connector section c2 from the connector section c1, and the cord 41 is pulled out from the cord reel 40 as necessary, and the operation panel CB is carried to an appropriate position to connect the connector section c2 to the cord 41. By inserting the connector into the connector portion c3 at the tip and operating the operating means 24A, the horizontal auger 12 is moved up and down and swirled, and the paddy is discharged. In this manner, the turning operation when the lateral auger is operated via the harness h2 is appropriately reduced in speed by the above-described speed reduction circuit.

According to this reference example, a single operating means 24
A is sufficient, so that the production cost is low, and when operating from the vicinity of the tip of the lateral auger 12, its turning operation is always slowed down to be safe.
Since no operating means is provided at the tip of the auger 2, the lateral auger 1
2 There is no obstruction at the tip end when running,
Further, since there is only a single operation means 24A, there is no need to consider the priority of the operation by each operation means as in the case where there are a plurality of operation means. The harness for the operating means can be shorter than when the means is provided.
