要があつた。 The handling cylinder of a threshing device such as a harvester rotates and threshes as the output of the prime mover is transmitted through the transmission system, but when the rotation speed of the handling cylinder decreases due to an increase in the load on the handling cylinder, the pulley in the transmission system As slips occur between the belt and the V-belt, the rotational speed of the handling cylinder further decreases, and the throughput of the handling cylinder further decreases. If this situation continues, there is a risk that the handling cylinder will become clogged and overloaded, which may eventually lead to the V-belt breaking. Therefore, a threshing device is known in which the rotational speed of the handling cylinder is variable using a transmission, and the handling cylinder can be driven at low speed and high torque in the event of an overload. However, such threshing equipment requires a handling drum load detection means that constantly monitors the load condition of the handling drum and notifies the operator. Conventionally, a rotation speed detector is installed on the handling drum shaft to detect this The result was used as a load on the handling torso. For this reason, it is necessary to electrically correct the detection result of the rotational speed detector or to change the reading on the display device depending on the gear position of the handling barrel transmission.

なる。 If the number of grain culms sent to the handling chamber 2 increases during the threshing operation, or if the handling chamber 2 becomes clogged with grain culms, the handling drum 4 becomes overloaded and the handling drum 5 becomes overloaded. The rotational speed decreases, and furthermore, the rotational speed of the threshing section input shaft 21 also decreases. In this situation, gear 21
a, 23a to the regulating shaft 23, and further transmitted to the detection shaft 9a via gears 23b, 24a, 9b, detected by the rotational speed detector 9, and notified to the operator. By slidingly moving the speed change gear 22 in the direction of the arrow A using the handling barrel transmission control lever that does not operate, the large gear 22a of the speed change gear 22 and the small gear 21a of the threshing section input shaft 21 are engaged with each other. Since the ratio of the rotational speed of the threshing section input shaft 21 to the threshing section input shaft 21 can be lowered than before to increase the torque, the threshing processing capacity is increased and the feed chain is reduced due to the decrease in the rotational speed of the threshing section input shaft 21. The reduction in the rotational speed of the drive shaft 25 reduces the speed at which the grain culms are delivered to the handling chamber 2 of the feed chain 6, that is, the amount of grain culms delivered per hour, and together with this, it is possible to eliminate the overload on the handling cylinder 4. becomes.

回転速度の比率をそれ以前よりも高くしてトルク
を減少させ得るので、扱胴４の軽負荷は漸次解消
される。 After the overload condition of the handling drum 4 is eliminated as described above, the handling drum 4 becomes lightly loaded, so that the rotational speed of the threshing section input shaft 21 increases. Rotation speed detector 9
detects the two conditions and notifies the operator through the display device 26. After confirming this, the operator slides the speed change gear 22 in the direction of the arrow B using an operation lever (not shown) to remove the small gear of the speed change gear 22. 22b and the large gear 21a of the threshing section input shaft 21, the ratio of the rotational speed of the handling drum shaft 5 to the threshing section input shaft 21 can be made higher than before and the torque can be reduced. The light load of 4 is gradually eliminated.

体、又はその表示の補正を行う必要はない。 Therefore, in the conventional device of this type, the rotational speed of the handling cylinder shaft 5 was detected as the load on the handling cylinder 4, so it was necessary to correct the detection result according to the gear stage of the handling cylinder transmission. In the present device, the rotational speed of the threshing section input shaft 21 is controlled by the part of the transmission system that is not affected by the handling cylinder transmission, that is, the part of the transmission system that is substantially closer to the prime mover than the handling cylinder transmission. Since the load is detected as a load, there is no need to correct the detection result itself or its display.

る。 As detailed above, the threshing device according to the present invention is
In a threshing device equipped with a rotational speed variable transmission for the handling drum and a load detector for the handling drum, the handling drum load detector is a transmission part of the handling drum that is substantially closer to the prime mover than the rotational speed variable transmission. Since it is designed to detect the load, it is possible to detect the load on the handling cylinder by installing a rotational speed detector in a part of the transmission system that is not affected by the handling cylinder transmission. The present invention has the following advantages: It is not necessary to correct the detection result of the rotational speed detector regardless of the set gear stage of the handling barrel transmission, and the device can be simplified and the failure rate is also reduced. It has excellent effects.

Although it was decided to provide a new detection shaft for the handling cylinder load detector, it is of course possible to use an existing rotating shaft that is not affected by the handling cylinder transmission in the transmission system.
