PURPOSE: To obtain the combine capable of lightly rotating a threshing cylinder with a small force and further capable of easily performing the clogged material-removing work of the threshing cylinder by projecting the driving shaft of a gear type speed reduction mechanism from a speed reduction case and disposing a connector for a manual handle at the end of the projected shaft. CONSTITUTION: In this combine, the threshing cylinder 7 of a threshing device 3 is driven through the gear type speed reduction mechanism 10, whose driving shaft 13 is projected from a speed-reduction case 11, and the connector 13A of a manual handle 16 is disposed at the tip of the projected shaft. The gear type speed reduction mechanism 10 is provided with an input shaft 12 having a pulley 12 mounted thereon, a bevel gear shaft 13 for changing the direction, a driving shaft 14 having a low speed gear 14a, a middle speed gear 14b and a high speed gear 14c attached thereto, and a passive shaft 15 on which a shift gear 15a capable of being alternatively occluded with the low speed gear 14a or the middle speed gear 14b of the driving shaft 14 and a floating gear 15b always occluded with the high speed gear 14c are mounted. The passive shaft 15 is preferably interlocked and connected to the rotation shaft of the threshing cylinder 7 through a coupling.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine, and more particularly to a technique for clearing a clogging of a handling room.

[0002]

2. Description of the Related Art Conventionally, when a material to be treated is clogged between a handling drum and a net in a handling chamber due to wet threshing or the like, a bar is hooked on a handling tooth of the handling barrel or a shaft in the longitudinal direction. The handle cylinder that rotates around the core is designed to remove the clogging by hooking a bar on a hole formed in the drive pulley and manually rotating the handle cylinder.

[0003]

In the means for removing the clogging by rotating the heavy handling cylinder directly with a bar or the like, a large force is required to rotate the heavy handling cylinder, and as a manual handle. Since a handle with a diameter large enough to withstand the large force required to rotate the handling cylinder is required, a large force is required to rotate the handling cylinder, which makes clog removal work difficult. It was a thing.

It is an object of the present invention to rotate the handling cylinder and remove the clogging so that the handling cylinder can be rotated with a small force so that the clogging removal work can be easily performed.

[0005]

The characteristic construction of the present invention for achieving the above object is to drive the handling barrel of a threshing device via a gear type speed reducing mechanism and to decelerate the drive side shaft of the speed reducing mechanism. It is projected from the case, and the connecting portion of the manual handle is provided at the protruding end.

[0006]

[Function] When the object to be processed is clogged between the handling cylinder and the net due to wet threshing, etc., if the manual handle is attached to the end of the drive shaft protruding from the deceleration case and the handle is rotated,
The reduction gear of the gear type reduction mechanism can be used to rotate the handling cylinder having a large mass.

Further, since a small force is required for turning the handle, a light handle having a small diameter can be used.

[0008]

As a result of the above construction, when carrying out the clogging removal work by rotating the handling cylinder using the manual handle, the handling cylinder can be lightly rotated with a small force and the handling cylinder clogging removal work is easy. Can be done.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an all-culm throw type combine, which is equipped with a threshing unit 3, a driving cabin 4, a Glen tank 5, etc. on a body 2 supported by a pair of left and right crawler traveling units 1. In addition to being equipped, a mowing pretreatment unit 6 is attached to the front part of the machine body so as to be vertically swingable around the horizontal axis X.

In the handling chamber provided in the upper part of the threshing device 3, a handling cylinder 7 having screw-type handling teeth in the peripheral portion is axially supported in the front-rear direction and the threshing processed material is passed through a receiving net 8 to select the lower portion. 9
It is configured to supply leakage to

In this combine, the rotation speed of the handling cylinder 7 of the threshing device 3 can be changed according to the type of crop such as rice and wheat and the properties of the crop such as wet threshing. As shown, on the front wall of the threshing device 3, a deceleration case 11 having a gear type deceleration mechanism 10 capable of three-speed shifting is installed.

The gear type reduction mechanism 10 includes a pulley 12
Input shaft 12 equipped with a, bevel gear shaft 1 for direction change
3, low speed, medium speed, high speed gears 14a, 14b, 14c
Drive shaft 14 having a fixed shaft, and a low speed gear 14 of the drive shaft 14.
The passive shaft 15 equipped with a shift gear 15a capable of selectively engaging with the a or the medium speed gear 14b, the high speed gear 14c, and the idle gear 15b always engaged with the passive shaft 1 is provided.
Reference numeral 5 is interlocked with the rotary shaft of the handling cylinder 3 via a coupling. The shift gear 15a is operated by a shift lever arranged outside the reduction gear case 11.

Therefore, the shift gear 15 of the passive shaft 15
By engaging a with the low speed gear 14a or the medium speed gear 14b of the drive shaft 14, a low speed first speed and a middle speed second speed state are obtained, and the shift gear 15a of the passive shaft 15 is coaxially attached to the idle gear 15b. By engaging them, a high speed third speed state can be obtained.

The front end of the bevel gear shaft 13 for changing direction is projected forward from the reduction gear case 11, and the end of the protruding shaft is formed as a polygonal angular shaft, and the connecting portion 13A of the manual handle 16 is provided. And the transmission gears 13a, 14d from the bevel gear shaft 13 to the drive shaft 14.
The rotation ratio is set to 1: 2, and the rotation force of the handle can be transmitted to the drive shaft 14 with a small force.

In this combine, when the manual handle 13 is turned, the handle 16 is turned while climbing on the threshing device 3, opening the top plate 3a of the threshing device 3 and watching the rotating state of the handling cylinder 7. Figure 2 so that you can
As shown in, a boarding step 17 is provided in the front part of the threshing device 3.

The boarding step 17 is performed by the deceleration mechanism 1
