Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine grain harvesting device, which can be effectively used as a combine of beans such as soybeans and adzuki beans.

[0002]

2. Description of the Related Art Generally, as a device for taking out harvested grains of combine harvesters for rice and barley, a take-up head, a taking-out direction, etc. are freely configured by using a spiral conveyor form. However, in the case of harvesting beans such as soybeans, if the discharge head of the harvested grain is set high, the grain surface is likely to be damaged, which causes quality deterioration. Therefore, by using a bucket conveyor type grain raising machine for discharging the harvested grain stored in this grain tank, it is possible to prevent damage to the discharged grain, but when moving or storing the combine. For example, since the bucket grain raising machine is always expensive, it is easy to get in the way.

[0003]

The present invention is directed to a traveling device 1.
In a combine in which a threshing device 4 for threshing a culm to be mowed by the mowing device 3 in the front part, a Glen tank 5 for accommodating grains to be threshed by the threshing device 4 and the like are mounted on a chassis 2 having By extending and contracting the hydraulic cylinder 8, the upper portion 7 of the bucket grain raising machine 6 for discharging the grains of the tank 5 to the outside of the machine is hinged 9 at a height near the upper portion of the Glen tank 5.
The harvested grain extracting device of the combine is provided so as to be capable of being folded in a horizontal state or a posture below this.

[0004]

By the combine work, the grain culms harvested by the harvesting device 3 are transferred to the threshing device 4 and threshed. Grains that are threshed by the threshing device 4 are stored and stored in the Glen tank 5. When the grains stored in the grain tank 5 are discharged to the outside of the machine, when the upper part 7 of the bucket grain raising machine 6 is in the folded posture, it is discharged around the hinge 9 by operating the hydraulic cylinder 8. Take a posture. Further, when the discharge in the Glen tank 5 is completed and the vehicle is traveling on the road or stored, the upper portion 7 of the bucket grain raising machine 6 is horizontally rotated by the hydraulic cylinder 8 or folded and rotated below a horizontal posture.

In this way, the upper part 7 of the bucket grain raising machine 6 is
Since the hydraulic cylinder 8 is swung up and down around the hinge 9 by expansion and contraction, it is possible to stand up to the discharge position only when necessary to facilitate operability and workability. The rotation speed of 7 can be set appropriately, and the up-and-down operation with little impact and rocking can be performed.

[Examples] The combine according to the present invention is effective for harvesting beans, but it can also be used for rice, wheat, and soybeans, adzuki beans, and other beans as "grains" and "culms". Define. In FIG. 1 and FIG. 2, the combine is a reel 10 on a chassis 2 having a crawler type traveling device 1.
The grain culm to be scraped by is cut, and the whole grain culm is supplied into the threshing chamber 11 of the rear threshing device 4 to thresh, and the mowing device 3 and the threshing device 4 in the form of all culms are mounted. On one side of 4, there is provided a cockpit 12 on the front part, a cabin 13 for covering the same, etc., a Glen tank 5 on the rear side, and an engine etc. covered with an engine cover 14 on the rear end part. .. Reference numeral 15 is a threshing cylinder in the threshing chamber 11, 16 is a transfer spiral at the bottom of the grain tank 5, and 17 is a bucket grain raising machine that takes out the grains that have been threshed and sorted by the threshing device 4 and transfers them to the grain tank 5. A bucket grain raising machine is provided.

The bucket grain raising machine 6 is erected on the rear side of the Glen tank 5, lifts the grains transferred to the rear by the rotation of the transfer spiral 16, and discharges the grain from the upper part 7 of the grain raising machine. Guide the discharge from 18 to the outside of the machine. At the height of the cabin 13, threshing device 4 to Glen tank 5, etc.
Is folds backward around the hinge 9, and the grain raising device 4
The front end of the discharge gutter 18 is supported by the rear end of the chassis 2 at a substantially horizontal position. At this time, the lower part of the bucket grain raising machine 6 is integrally formed with the gren tank 5 side, and the bucket elevator 19 stretched inside is also bent around the hinge 9.

The folding rotation of the upper part 7 of the grain raising machine is carried out by a hydraulic cylinder 8 which is hydraulically expanded and contracted between the upper part 7 and the lower part, and is carried out at an appropriate rotational speed by operating a valve of a hydraulic circuit. Reference numeral 20 denotes a gutter which connects the rear end of the transfer spiral 16 and the lower end of the bucket grain raising machine 6 with a shutter 21. The transmission configuration of the bucket elevator 19 is performed by interlocking the pulley shaft 22 at the upper end portion. The belt 2 is provided between the pulley shaft 22 and the intermediate shaft 23 on the hinge 9.

A belt 26 interlocks with the pulley shaft 25 at the upper end portion, and by interlocking the bucket grain raising machine 17 from the threshing device 4, the pulley shaft 25 → belt 26 → intermediate shaft 23 → belt 24 → pulley shaft 22 → It is transmitted on the path of the bucket elevator 19. Reference numeral 27 is a lower pulley shaft. 28 is a tension clutch pulley of the belt 26. When the upper part 7 of the bucket grain raising machine 6 is folded, the upper part 7 of the grain raising machine can be folded along the lower part by folding or removing the discharge gutter 18 without any rearward protrusion. Can be stored more easily.

Since the expansion and contraction of the hydraulic cylinder 8 is performed by valve operation and control in the hydraulic circuit, the expansion and contraction speed is set by the amount of oil in the hydraulic circuit, and the undulating rotation speed of the upper part 7 of the grain raising machine is made slow. It is possible to rotate without causing a large impact or vibration. 3 and 4, the points different from the above example are a spiral grain raising machine 29 for rice and wheat,
A bucket raising machine 30 for raising beans is separately provided. The spiral grain raising machine 29 is erected at the rear end portion of the transfer spiral 16, and the upper portion 31 can be horizontally swiveled with respect to the lower portion so that it can be vertically swung up and down.

I am trying. 34 is the upper part 31
It is a hook that connects the bucket and the grain raising machine 30. The interlocking operation of this bucket elevator 32 is performed by the pulley shaft 3 at the upper end.
5 is performed by driving the bucket grain raising machine 30 upright and the belt 3 from the shaft 36 at the upper end of the spiral grain raising machine 29.
Interlock with 7. The shaft 36 is configured to be taken out from the interlocking shaft 40 portion between the upper and lower spiral shafts 38 and 39 in the spiral grain raising machine 29 by bevel gear transmission, and these spiral shafts 38 and 39 are
By being transmitted from the side of the transfer spiral 16 at the bottom of the Glen tank 5 via a clutch, the shaft 36 → the belt 3
7 → The bucket elevator 32 can be transmitted via the pulley shaft 35 and the like.

Further, the upper part 31 of the spiral grain raising machine 29 is controlled to be swung or raised and lowered by expanding and contracting a hydraulic cylinder (not shown).
And the bucket grain raiser 30 by connecting the
The pulley shaft 33 is utilized by utilizing the turning power of the upper part 29 of the spiral grain raising machine.
It is possible to swing up and down around the bucket
Can be lowered so as not to disturb the movement and storage of the combine. Although the posture in which the bucket grain raising machine 30 is erected is held by the hook 34, it may be configured such that it is separately fixed to the chassis 2 to the Glen tank 5 or the like by a fixing tool.

7 to 9 are different from the above example in that
Driving the bucket elevator 32 of the bucket grain raising machine 30 by interlocking the transmission clutch 41 of the bucket grain raising machine 30 with the opening / closing of the shutter 21 provided in the gutter 20 that communicates with the bucket grain raising machine 30 from the Glen tank 5. At the same time, or in conjunction with opening the shutter 21 later than this drive, clogging of the bucket grain raising machine 30 at the start of grain discharge is prevented.

The transmission clutch 41 is provided as a belt tension clutch on the transmission belt 42 which is transmitted from the engine E to the transfer spiral 16. The bucket elevator 32 is transmitted from the 16 axes of the transfer spiral via the belt 43 and the like. The interlock between the transmission clutch 41 and the shutter 21 is
When the transmission clutch 41 is engaged, the shutter 21 opens,
Further, the shutter 21 is closed when the transmission clutch 41 is disengaged, so that the shutter 21 is mechanically or electromagnetically interlocked.
