Background technology
Still be at present the Xinjiang-2 self-propelled axial flow grain combine self-unloading tanker of conceptual phase, also have integrity problem to some extent, sum up and get up to mainly contain four problems:
(1) the unloading screw conveyor axial locking adopts eccentric bushing and steady nail, can not under unloading operation vibration environment, bear larger axis to power (particularly unloading moist seed), once locking was lost efficacy, will cause with transition screw feeder and the stack of horizontal screw conveyor axial force, horizontal screw conveyor supporting friction pair was lost efficacy in advance.
(2) transition screw feeder bearing and horizontal screw conveyor left bearing adopt oscillating bearing, often can not bear larger axis and lose efficacy in advance to power.
(3) the universal joint transmission belongs to the angle transmission between transition screw feeder and the horizontal screw conveyor, produces small axial displacement in the motion, and it is unreasonable to adopt general flat key to connect.
(4) switching mechanism pivoted arm and hinge axis adopt elastic cylindrical pin to connect, and can not bear the shearing force that produces than high pulling torque in the starting opening procedure, are often cut off.
(5) switching mechanism hinge axis intermediate support is indeterminate supporting hinge, aspect installation regulatory function is not arranged, and produces additional internal stress easily in rotation.

Embodiment
As Fig. 1, Fig. 2, Fig. 5, Fig. 6, shown in Fig. 7 and Fig. 8 are common, combine is from the unloading device, comprise tanker 1, on the described tanker 1 unloading tube 2 is installed, horizontal screw conveyor 3 and the switching mechanism that is positioned at described horizontal screw conveyor 3 tops are installed in the described tanker 1, in the described unloading tube 2 unloading screw conveyor 4 is installed, the lower end of described unloading screw conveyor 4 is connected with transition screw feeder 5, the upper end of described unloading screw conveyor 4 is installed on the described unloading tube 2 by bearing, be provided with axial locking device between described unloading screw conveyor 4 and the described bearing, described horizontal screw conveyor 3 is connected by universal joint 7 with described transition screw feeder 5, and the axial locking device of described unloading screw conveyor 4 is eccentric bushing 41 and the double nut 42 that compresses described eccentric bushing 41.This locking device can bear larger axis to power (particularly unloading moist seed) under unloading operation vibration environment, farthest reduced the problem that locking was lost efficacy.
As shown in figure 10, described horizontal screw conveyor 3 is respectively bearing with spherical outside surface 10a, 10b with the block bearing of described transition screw feeder 5, is respectively equipped with seal protection lid 11a, the 11b of awl arc on the bearing block of described bearing with spherical outside surface 10a, 10b.Bearing with spherical outside surface can bear larger axis to power; guaranteed not can be because of the axial force of bearing bigger described horizontal screw conveyor and the described transition screw feeder transmission failure of making; simultaneously the seal protection lid is set the service life that has prolonged bearing with spherical outside surface, and make unloading more smooth and easy.
The universal joint transmission belongs to the angle transmission between transition screw feeder 5 and the horizontal screw conveyor 3, produces small axial displacement in the motion, and it is unreasonable to adopt general flat key to connect.In order to address this problem, described universal joint 7 is connected by spline 12 with described transition screw feeder 5 with described horizontal screw conveyor 3 respectively.
As Fig. 3, shown in Fig. 4 and Figure 11 are common, described switching mechanism comprises the inverted V-shaped securing cover plate 6a that is fixedly mounted on described horizontal screw conveyor 3 tops, be provided with grain-entering mouth between described inverted V-shaped securing cover plate 6a bottom and the described tanker 1, removable cover 6b and back removable cover 6c before described grain-entering mouth place is provided with respectively, removable cover 6b and back removable cover 6c are fixedly mounted on respectively and cover handle 6d before described, on the 6h, described lid handle 6d, 6h is hinged on the cursor 6j, described cursor 6j is fixedly mounted on the hinge axis 6e, described hinge axis 6e middle part is equipped with the intermediate supports beam 6f that supports described hinge axis 6e, the end that described hinge axis 6e stretches out described tanker 1 is connected with the pivoted arm 9 that is driven by power set, and described hinge axis 6e is connected by the flat key 13 that can clamp with described pivoted arm 9.Described hinge axis 6e is connected by flat key 13 with described pivoted arm 9, can bear the shearing force that produces than high pulling torque in the starting opening procedure.
