Description

[Detailed description of the invention] The present invention is designed to drive the car wash pump by using the driving force of the threshing section, and to install the car wash pump so that it is placed horizontally in the threshing section so that it can be removed to prevent it from running idly during operation. Regarding the structure of a pump mounting part in a combine harvester that is separably coupled to a rotating shaft, the purpose thereof is to enable easy operation of the pump attachment and detachment.

The characteristic configuration of the present invention is that, in the structure of the pump mounting part of the combine harvester described above, an engagement part that holds the pump movably in a direction that allows the engagement and disengagement of the input shaft of the pump and the fitting part of the rotating shaft. Department,
A fastener is provided between a bracket fixed to the machine body and a pump side member in a state that the fastener is engaged and disengaged by movement of the pump in the direction of the input axis, and fixes the pump to the bracket. The pump is provided between the member and the bracket in a state in which the pump is forcibly moved in the direction of the input shaft thereof, and an engagement clutch between the input shaft and the rotary shaft is engaged and disengaged by the movement in the direction of the input shaft of the pump. This is because we have set it up.

In other words, by making the engaging part, the tightening tool, and the clutch of the above-mentioned working type, when installing the pump, the input shaft and the rotating shaft can be brought together so that they are concentric or almost concentric. Simply, the rotating shaft and input shaft engage, the pump and bracket engage, and all that is left to do is tighten and secure the pump.Furthermore, all you have to do is operate one tightening screw. As the pump is tightened to the bracket, even if the engagement of the clutch is shallow, the tightening force causes the pump to move toward the rotating shaft, and the input shaft can be reliably engaged with the rotating shaft. On the other hand, the fixation of the pump can be released by simply releasing one fastener, and by simply moving the pump in the direction of the input shaft away from the rotating shaft, the clutch and the engaging portion are released. The pump can be removed. Therefore, it has become extremely easy to install and remove the pump so that it can be driven smoothly by simply driving the pump and operating one tightening screw.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in Fig. 1, a reaping section 1 that reaps the planted grain culm while raising it and conveys the reaped grain culm to the rear of the machine is connected to a driving section 2, a driving section 3, and a threshing section for the grain culm from the reaping section 1. A combine harvester is constructed by being connected to the front part of a crawler-type traveling machine body having a section 4, a bagging section 5 for threshed grains, and the like.

As shown in FIG. 2, a gear pump 6 as an example of a car wash pump is installed in the bagging section 5, and a water suction hose 8 with a strainer 7 for sucking water from an irrigation canal, etc., and a car wash hose 9 are installed as pumps. It is attached to 6.

To provide the pump 6, as shown in FIGS. 3 to 5, a cylindrical portion 12a is provided on the passive belt pulley 12 of the rotating shaft 11 for driving the dust removal fan, which is mounted laterally on the wall 10 of the threshing machine. At the same time, a cylindrical body 13 that can be detached and fitted onto the cylindrical portion 12a is attached to the input shaft 6a, and the input shaft 6 of the pump 6 is attached to the input shaft 6a.
The input shaft 6a is connected to the rotating shaft 1 by concentrically or almost concentrically connecting the input shaft 6a and the rotating shaft 11, and by moving the pump 6 in the direction of the input shaft.
1, and a pump bracket 18 is fixed via a support member 17 across the threshing machine wall 10 and the attachment member 16 of the bag support rod 15. Then, two locking pins 19, 19 are attached to the bracket 18, and a pump hanging member 20, which can be freely engaged and detached from the locking pins 19, 19, is attached to the pump 6, and the fitting portion 14 is attached to the pump 6. An engaging portion 21 is configured to hold the pump 6 in a state in which it can be engaged and disengaged from the input shaft 6a, and to enable the pump 6 to be engaged and disengaged from the bracket 18 by moving the pump 6 in the direction of the input shaft center. The rotating shaft 11 is suspended and held by a bracket 18 so that the rotating shaft 11 is concentric or substantially concentric. A single tightening bolt 22 that acts on the hanging member 20 in the direction of the input axis of the pump 6 is screwed onto the bracket 18, and the pump 6 is fastened to the bracket 18. A mounting member 23 for the input shaft 6a of the cylindrical body 13 and each of the pulley cylindrical portion 12a,
Mutually engageable and disengageable clutch pawls are attached to form an interlocking clutch 24 for interlockingly connecting the pump to the rotating shaft 11, and this clutch 24 can be operated by moving the pump 6 in the direction of the input shaft. It is configured to be detachable.

In short, the pump 6 can be attached and detached by simply driving the pump 6 using the driving force of the threshing section 4, moving the pump 6 in the input shaft direction, and operating one tightening bolt 22. I have made it possible.

In addition, the cushion rubber 2 shown in FIGS. 3 and 5
5 is by allowing the pump 6 to vibrate due to the misalignment even if the input shaft 6a rotates eccentrically due to play in the fitting portion 14, This is designed to prevent abnormal friction between the gear and the casing.

In place of the tightening bolt 22, use the bracket 1.
A tightening nut or the like that is screwed onto a bolt fixed to the bolt 8 may be employed, and these are collectively referred to as the tightening tool 22.

The present invention can also be applied to cases where various rotating shafts such as an oscillating sorting plate drive shaft are used as the drive shaft of the pump 6.
