Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover structure of a grain culm raising device, and is used in a harvesting machine such as a combine harvester.

[0002]

2. Description of the Related Art Conventionally, there is a technique described in Japanese Utility Model Publication No. 55-166446.

[0003]

SUMMARY OF THE INVENTION The present invention is to eliminate the problems of the prior art described in the above publication. That is, the purpose of the present invention is to facilitate the attachment and detachment of the raising cover and to protect the headlight itself by raising the headlight that irradiates the front of the mowing unit and storing it in the cover. To achieve this object, the present invention takes the following technical means.

[0004]

That is, the technical means according to the present invention is formed on the upper part of the raising case 5 of the grain culm raising device 1 so as to cover the upper part of the raising case. The front cover 6 and the rear cover 7 are detachably connected to each other,
An opening window 14 for a headlight is provided at an appropriate position on the front cover, and a headlight 15 facing the opening window is mounted in a space between the front cover 6 and the rear cover 7. The cover structure of the grain culm raising device is as follows.

[0005]

The front cover and the rear cover can be easily attached to and detached from the bracket attached to the raising case.
Even if the long culm is entangled and entangled with the upper part of the case, the entanglement can be easily removed by removing the cover. Since the headlight that illuminates the front of the reaping unit is housed in the space between the front cover and the rear cover, there is no entanglement of the grain stems and it is possible to protect it safely.

[0006]

According to the present invention, therefore, the raising cover can be easily attached and detached, so that even if a grain culm is entangled with the upper portion of the raising case, it can be easily removed. Since the headlight is housed in the cover, the headlight does not have the entanglement of the grain stem unlike the conventional device that is mounted on the front or upper part of the cover and can be safely protected. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 is a lateral turning type raising device that raises a grain culm while moving a raising lug 2 in a laterally protruding posture upward, and three grain culm raising devices 1, to form a three-row grain culm raising passage.
1, 1 are arranged side by side at predetermined intervals in the lateral direction. Reference numeral 3 denotes a rotary type raising device which raises the grain culm while moving the raising lug 4 in the forward protruding posture upward, and is arranged at the front part of the horizontal turning type raising device 1.

Reference numeral 5 denotes a raising case of the raising device 1, which comprises a front case 5a and a rear case 5b. 6 and 7 are a front cover and a rear cover which cover the upper part of the raising case 5.
The covers 6 and 7 are detachably fastened and fixed to the bracket 9 attached to the rear case 5b by the bolts 8 with screws 10 and 11. 10a is a front cover
6 is a screw hole provided on the 6 side, 10b is a screw hole provided on the bracket 9 side, 11a is a screw stop notch provided on the rear cover 7 side, and 11b is a screw hole provided on the bracket 9 side.

A projection 12 is provided on the bracket 9 side, and a locking hole 13 for fitting and locking the projection 12 is provided on the rear cover 7 side. Opening windows 14 and 14 for headlights are provided at two positions on the left and right of the front cover 6, and the headlights 15 facing the opening windows 14 and 14 are the front cover 6 and the rear cover 7. It is installed in the space between the bracket 16 and the mounting piece 17, and is fastened with bolts 20 and 21 to the mounting piece 19 welded to the bracket 18 side stay 18 and the rear case 5b. It is fixed.

Reference numeral 22 is a sward bar, 23 is a stub body attachment stage,
Reference numeral 24 is a mounting stage for the rotary type raising device 3, and
23 and 24 are attached with two tightening bolts 25 and 26. 27 is a drive shaft for raising, 28 is a drive sprocket for raising, 29 is an input shaft for raising vertically, and the bevel gear mechanism 3
It is interlockingly configured to drive the rotary type raising device 3 via 0. The raising drive shaft 27 and the vertical raising input shaft 2
9 is spline-fitted so that both shafts can be fitted and removed freely. Then, the upper end of the rotary type raising device 3 is clamped and fixed to the front case 5a side by the knob 31. According to this structure, if the knob 31 is rotated to raise it to release the fixed state with respect to the case 5, and one of the tightening bolts 26 on the lower end side is removed, this rotation type raising device is obtained. 3 is capable of swinging and opening the upper end side forward largely with the other tightening bolt 25 on the lower end side as the center of rotation. At this time, the vertically-raised input shaft 29 is detached from the vertically-raised drive shaft 27.

Reference numeral 32 denotes a side cover which raises and covers the side of the reaping section. The side cover 32 raises and lowers a tubular fitting tube 33 provided at one end thereof on the side surface of the case 5. The pin shaft 34 is inserted into the pin shaft 34 in the direction from above to be set, and the pin shaft 34 in the up and down direction is configured to be swingable and openable about the turning center. Reference numeral 35 denotes a rod-shaped locking rod fixed to the inner surface of the side cover 32 so as to lie along the front-rear width direction via a mounting seat plate 36. The locking rod 35 closes the side cover 32. In this state, the engagement holder 38 made of an elastic material provided on the cutting frame 37 side is engaged and retained in a detachable manner.

Reference numeral 39 is a guide member having a guide groove 39a for guiding and guiding the locking rod 35 to the engaging holder 38. Therefore, the guide member 39 has a guide groove 39a. The engagement holder 38 is attached at a position corresponding to. Therefore, according to this structure, the side cover 32 can be opened with one touch. Further, the locking rod 35 can also serve as reinforcement of the side cover, and the rigidity of the cover itself is increased.
