DETAILED DESCRIPTION OF THE INVENTION
The Glen tank 3 is mounted on the side of the threshing device 8 at the rear of the combine vehicle body 7. The upper end portion of the cerealing machine 9 at the end of the threshing device 8 provided at the bottom of the threshing device 8 is placed on the glen tank 3, and the grain that has been threshed is accommodated in the glen tank 3.
[0006]
The Glen tank 3 is provided with a grain shed 2 along the front-rear direction at the bottom, a discharge port 5 at the rear end, and an elbow-shaped grain shed 10 on the rear side. In addition, a vertical auger 11 and a swivel auger 12 and the like are connected to the grain removing cylinder 10 so that the grains can be conveyed to the tip grain outlet 13 and discharged.
The grain helix 1 is mounted along the grain hull 2, and the grain flowing into the grain hull 2 by the rotation of the grain helix 1 can be conveyed to the outlet 5 side. Reference numeral 14 denotes a flow dividing plate provided along the upper side of the threshing spiral 1.
[0007]
The bottom part of the grain tank 3 has a wide threshing device 8 side of the grain shed 2 and is provided with an inclined bottom 4 that is inclined downward toward the grain shed 2 side from the front end toward the rear. The accommodated grains are allowed to flow down along the inclined bottom 4.
On the rear discharge port 5 side of the inclined bottom 4, a steeply inclined bottom 6 that is steeper than the inclined bottom 4 is formed. The steeply inclined bottom 6 is formed on the upper side of the bent edge 15 in the inclined direction from the upper end edge of the inclined bottom 4 at the substantially intermediate portion in the front-rear direction of the Glen tank 3 to the discharge port 5. The grain is allowed to flow quickly through the steep bottom 6 in the vicinity.
[0008]
The grain in the glen tank 3 is discharged from the grain shed 2 to the outlet 5 by the rotation of the grain milling spiral 1. At this time, since the grain guided by the steep bottom 6 near the discharge port 5 flows down quickly, the discharge to the discharge port 5 side is smoothly performed, and high-efficiency threshing can be performed. it can.
The combine vehicle body 7 includes a crawler traveling device 16, and a cutting device 17 and a cabin 18 are mounted on the front portion. The cereals harvested by the reaping device 17 are transported through the transporting device 19, supplied between the feed chain 20 and the cocoon 21 of the threshing device 8, and transported by the feed chain 20 while the threshing chamber 26. It is threshed by the inner handling cylinder 24.
[0009]
In the lower part of the threshing device 8, an oscillating sorting shelf and the like for oscillating and sorting upon receiving the cereal are provided in the sorting chamber 22. An engine 25 is mounted in an engine cover 23 at the lower rear portion of the cabin 18. 27 is a waste chain, 28 is a waste cutter.
5 and 6, the transmission configuration of the threshing device 8 and the Glen tank 3 will be described. A counter shaft 31 in the horizontal direction is mounted below the cereal supply port funnel 30 on the front wall 29 of the threshing device 8, and the belt between the engine shaft 32 and the engine shaft 32 is provided at the end of the counter shaft 31. 33, a belt 37 is passed between the upper processing cylinder shaft 34 and the input shaft 36 of the front part of the bevel gear case 35, and the input shaft 40 of the upper bevel gear case 39 of the front part of the upper handling cylinder shaft 38. A belt 41 is stretched between them and the handling cylinder 24 and the processing cylinder 42 are interlocked.
[0010]
Further, from the end of the counter shaft 31 on the feed chain 20 side, the first helix 45, the second helix 46, the red pepper 47, etc. of the threshing sorting chamber are interlocked via belts 43, 44. From the first spiral 45, the masher 9 is interlocked, and an input shaft 50 of the gear case 49, an input shaft 52 of the swing sorting shelf 51, a cutter shaft 53 of the staking cutter 28, and the like via a belt 48. Interlock.
[0011]
Thus, the counter shaft 31 is provided at the lower portion of the front wall 29 of the threshing device 8, and the belts 41, 37 between the input shaft 40 of the upper handling cylinder shaft 38, the input shaft 36 of the processing cylinder shaft 34, etc. Since it is provided along the front wall 29, the interlocking mechanism is simplified and the space in the front-rear direction can be shortened.
Among them, the gear of the gear case 49 interlocks with a suction dust remover 54 provided at the lower portion of the exhaust chamber, and the chain shaft 55 of the feed chain 20 is interlocked via a dog-shaped chain clutch 56. Reference numeral 57 denotes a second cereal machine interlocked with the second spiral 46.
[0012]
The exhaust chain 27 is interlocked to the input shaft 62 of the bevel gear 61 from the rear end of the cylinder shaft 38 on the rear side of the cylinder arm 60 via the belt 58, the tension pulley clutch 59, and the like.
Further, the grain helix 1 of the Glen tank 3 is interlocked from the engine shaft 32 via a belt 63, a bevel gear 64, a chain 65, and the like.
[0013]
In the transmission mechanism as described above, as shown in FIG. 7, the clutch arm 67 is interlocked via the crank rod 66 by the geared motor M1, and the chain clutch 56 of the feed chain 20 can be turned on and off. A wire 69 is connected to the crank rod 66 between the tension clutch arm 68 and the base of the tension clutch arm 68.
[0014]
Thus, when the geared motor M1 is driven, the chain clutch 56 is disengaged and the feed chain 20 is stopped, and the tension pulley clutch 59 is disengaged and the exhaust chain 27 is stopped. Reference numeral 70 denotes a clutch spring that constantly repels the tension pulley clutch 59 toward the on-side.
8 is different from the above example in that a clutch sensor SW1 including a limit switch for detecting the operation of the clutch arm 67 of the feed chain clutch 56 is provided to detect the stop state of the feed chain 20 and the exhaust chain 27. Let In addition, a clogging sensor SW2 including a limit switch is provided in the waste takeover portion between the terminal end portion of the feed chain 20 and the start end portion of the waste chain 27, and is turned on when the waste stays in the takeover portion. Alarm can be transmitted.
[0015]
In such a configuration, an alarm buzzer is transmitted when the clogging sensor SW2 detects clogging of the cereal during normal cutting operations. However, when it is detected by the clutch sensor SW1 that the feed chain 20, the exhaust chain 27, etc. are stopped, even if the clogging sensor SW2 is turned on, an alarm buzzer is not transmitted and the engine 25 can be driven. I can't do it.
[0016]
In this case, if a time lag is provided in the stop and start times of the feed chain 20 and the waste chain 27, the waste will temporarily stagnate in the takeover part, but the waste clogging sensor SW2 rarely erroneously detects this. Become.
In FIG. 9, the difference from the above example relates to a controller 71 that sets a certain time lag for turning on and off the chain clutch 56 of the feed chain 20 and the clutch 59 of the exhaust chain 27. When stopping due to the output from the controller 71, the output chain 27 is stopped for a moment earlier than the feed chain 20, and when activated, the output program is started so that the feed chain 20 is started for a moment earlier than the rejection chain 27. Set.
[0017]
The drive of the feed chain 56, the exhaust chain 59, etc. is operated by a separate geared motor. Further, the cutting clutch 72 provided in the transmission mechanism of the cutting device 17 is also operated by the same geared motor.
When it is detected by the cutting lift sensor SW3 that detects the lifting position of the cutting device 17 that the cutting device 17 has been raised to the non-cutting position, the cutting clutch 72 is cut off and the cutting transmission is stopped. When the waste chain clutch 59 and the feed chain clutch 56 are turned off, the waste transport by the feed chain 20 and the waste chain 27 is stopped.
[0018]
At this time, because the output from the controller 71 is output to the exhaust chain clutch 59 earlier than the feed chain clutch 56, the exhaust chain 27 is stopped earlier.
On the other hand, when the cutting device 17 is lowered to the cutting posture and restarted, the feed chain 20 is driven instantaneously earlier than the rejection chain 27.
[0019]
In this way, in the takeover part between the feed chain 20 and the waste chain 27, the waste transport is slightly stagnant in both the stop and start, and the waste chain 27 is prevented from being swept away. The forced scraping can be reduced, and the disturbance of evacuation is reduced.
