Abstract

The discharge straw discharge device of the combine has a receiving member (28) capable of oscillating around an axis (P3) along the left and right directions. When not receiving discharge straw, the receiving member (28) is positioned in a receiving position where it extends from the axis (P3) toward the rear and the oscillating end of the receiving member (28) is positioned higher than the base of the receiving member (28). When the weight of the discharged straw received reaches a predetermined weight, the receiving member (28) oscillates downward from the receiving position to discharge the discharged straw into the packaging and returns to the receiving position. The receiving member (28) can change its position to a non-use position (A3) that extends downward from the axis (P3).

Description

combine The present invention relates to a configuration for discharging discharged straw into a package in a combine. In a combine, as disclosed in Patent Document 1, a conveying device for discharge straw is provided to convey discharge straw, which is a grain that has finished threshing treatment, from the threshing device toward the rear in a sideways tilted position, and a receiving member is provided below the end portion of the discharge straw conveying device. The receiving member receives the discharge straw that has fallen from the end of the discharge straw conveyor device in a receiving position extended toward the rear. When the weight of the discharge straw received and accumulated in the receiving member reaches a predetermined weight, the receiving member swings downward from the receiving position, and the discharge straw is discharged from the receiving member into the packaging, and thereafter, the receiving member returns to the receiving position. Accordingly, when the discharge straw that has finished threshing treatment comes out continuously from the threshing device and the discharge straw conveying device, the discharge straw is collected in a predetermined amount and discharged into the packaging, and this state is repeated.

(Overall composition of the combine) As shown in FIG. 1, right and left crawler-type driving devices (2) are installed on the body (1), and the body (1) is supported by the driving devices (2). A harvesting unit (3) and a driving unit (4) are provided in the front part of the body (1), and a threshing device (5) and a grain tank (6) are provided in the rear part of the body (1). A discharge straw discharge device (41) is provided in the rear part of the body (1), in a portion further rear than the threshing device (5) and the grain tank (6). As the machine (1) advances, the grain stalks of the package are cut by the cutting unit (3), and the cut grain stalks are changed to a sideways position and conveyed to the rear, and the stump side of the grain stalks is delivered to the feed chain (7) of the threshing device (5) and conveyed to the rear. As the stump side of the grain stalks is conveyed to the rear by the feed chain (7), the end portion of the grain stalks is threshed by the threshing device (5), and the grains are recovered and stored in the grain tank (6). As illustrated in FIGS. 1, 2, and 3, the threshing process is completed, and the straw is conveyed as discharge straw from the threshing device (5) in a sideways tilted position by the discharge straw conveying device (8) in a rearward inclined right direction, supplied from the end of the discharge straw conveying device (8) to the discharge straw discharge device (41), and discharged into packaging from the discharge straw discharge device (41). The discharge straw discharge device (41) has a cover (10), a guide plate (27) (corresponding to the guide section) (corresponding to the partition wall section), an axle member (34), a receiving member (28), and a guide member (33), as described below.
