Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a turning device of a grain carrying-out device which also serves as an opening / closing device of a bulking tank.

(B) Conventional technology Conventionally, Japanese Utility Model Publication No. 57-57554 and Japanese Patent Application Laid-Open No. 61-1
As shown in each publication of No. 324, an increase tank is attached to a Glen tank for storing grains from the threshing section so that it can be freely extended.
There was a technology to store the expansion tank compactly in the Glen tank for running on the road and to extend the expansion tank to increase the capacity of the Glen tank for harvesting work.

Further, as disclosed in Japanese Utility Model Application Laid-Open No. 60-180216, a technique for connecting a vertical screw conveyor of a grain discharging device communicating with a grain tank to a swivel rack mechanism so that the discharge direction of a discharge port of the conveyor can be changed. was there.

(C) Problems to be solved by the device However, in the increasing tank having the above configuration, the overhanging and storing work of the tank is performed manually by the operator, so that the above work is performed in the middle of the harvesting work. In addition, there is a drawback that the efficiency of the harvesting work is reduced because the driver has to get off from Conban.

In order to eliminate this drawback, a mechanism for mechanically performing the overhanging and storing operation of the bulking tank has been devised, but the structure is complicated, and the turning mechanism of the vertical screw conveyor of the grain discharging device described later is However, there is a drawback in that the structure is further complicated by requiring separate mechanisms, and the operation is complicated because both mechanisms are operated separately.

(D) Means for solving the problem In this invention, an increase tank is attached to the Glen tank,
The expansion tank is rotatably extended around the expansion tank rotation axis provided between the lower end edge of the same expansion tank and the outer wall of the Glen tank, and the lower end of the vertical screw conveyor is connected to the Glen tank. The upper screw conveyor is connected to the upper end, and the discharge port provided at the end of the upper screw conveyor is rotatable around the vertical screw conveyor by the discharge port changing mechanism. A pinion is fitted above the gear and linked to the discharge port turning mechanism of the vertical screw conveyor.A hydraulic cylinder is erected below the gear, and both the gear and the pinion are installed on the cylinder. Grain unloading device that doubles as an opening / closing device for a bulking tank, which is capable of meshing, but has a rack that meshes only with one of the gear and pinion at one time. There is provided a rotating device.

(E) Action / Effect According to this invention, one rack connected to the hydraulic cylinder can be engaged with both the gear of the increasing tank rotating shaft and the pinion of the vertical screw conveyor rotating mechanism, and
Since it is configured so that it can be meshed with only one of the above at one time, the lower end of the rack is meshed with the gear of the rotating shaft when storing the increase tank, and the hydraulic cylinder is in the middle of the harvesting work. To extend the storage tank by overhanging the gear to extend the storage tank, and at the end of the extension operation, the rack is disengaged from the meshing gear, or the reverse operation is performed to extend and store the storage tank. It is possible to do just that.

Further, when the hydraulic cylinder is further extended from the above-mentioned extended state, this time, it is meshed with the pinion of the rotating mechanism of the vertical screw conveyor, and the pinion is rotated to change the discharge port of the grain discharging device. It can be carried out.

As described above, it is possible to individually operate both the opening / closing operation of the expansion tank and the discharge port turning operation of the grain discharging device by only the expansion / contraction operation of one hydraulic cylinder, which simplifies the structure. Since only one hydraulic cylinder needs to be controlled, the operation becomes easy and the operating device can be simplified.

(F) Embodiment An embodiment of the present invention will be described in detail with reference to the drawings.
In FIG. 2, (A) shows a combine, (1) is a frame equipped with a traveling crawler (2), (3) is a threshing section provided on the frame (1), (4) is a feed chain, ( 5) is a handle barrel, (6)
Is a grain tank for storing grains from the threshing unit (3), (7) is the operating unit, and (8) is the reaping unit. Cutting grain culms, threshing section
Threshing is carried out in (3), and a sorting section provided thereunder separates straw into refined grains and refined grains, and the refined grains are temporarily stored in the Glen tank (6).

The Glen tank (6) is equipped with an increase tank (9) for increasing the capacity of the tank (6).
As shown in FIG. 3, the increasing tank rotating shaft (11) is laid across the outer wall (10) of the Glen tank (6), and the coaxial (11) has an inverted triangular shape in a front view and a substantially U-shape in a plan view. Attach the lower edge of the increasing tank (9), and configure it so that the expanding tank (9) can be extended outside the machine and rotated about the coaxial shaft (11) to increase the capacity of the Glen tank (6). The coaxial (11) is extended rearward and the gear (12) is fitted to the rear end of the coaxial (11). It is designed to be extended and stored.

Further, a grain discharge device (14) is connected to the grain tank (6) for communication, and the same device (14) has a lower screw conveyor (15) arranged in the front-rear direction at the bottom of the grain tank (6). hand,
The grain in the tank (6) is transferred backward and
5) The lower end of the vertical vertical screw conveyor (16) is connected to the rear end of the vertical conveyor, the grain is conveyed upward by the conveyor (16), and it can be swung up and down on the upper end of the conveyor (16). Discharge port provided at the end of the upper screw conveyor (17) connected to
From (18), the grain can be carried out, for example, to the loading platform of a truck.

The grain carrying-out device (14) is a vertical screw conveyor.
The lower end of (16) is horizontally rotatably connected to a connecting casing (19) fixed to the rear end of the lower screw conveyor (15),
The discharge port (18) of the device (14) can be changed over the entire circumference of the combine (A), and the discharge port changing mechanism (20) is
As shown in FIG. 3, the large bevel gear (20a) is fitted on the outer peripheral surface of the casing (16a) of the vertical screw conveyor (16) at a position higher than the gear (12), and is added to the gear (20a). The small bevel gear (20c) fitted to the output shaft of the speed mechanism (20b) meshes with the same mechanism (20b).
Fit the pinion (20d) to the input shaft of the pinion (20d)
Are positioned substantially vertically above the gear wheel (12) with a predetermined interval.

Further, a hydraulic cylinder (21) is erected on the frame (1) substantially vertically below the gear (12) and the rod (21a) of the cylinder (21) is installed.

The expansion / contraction operation of the hydraulic cylinder (21) is controlled by a hydraulic valve (not shown) interlocking with the lever (22) provided in the operating unit (7), and therefore, the operator has only one lever (22). It is possible to control both of the above operations individually.

When the discharge port (18) of the grain export device (14) is deflected and rotated, the expansion tank (9) is kept in the overhanging state, but the grain export operation is performed in the field, and Combine
Since it is performed in the stopped state of (A), there is no problem even if the expansion tank (9) is overhanging, and during the harvesting work, the Glen tank (6) becomes full and the expansion tank (9) is expanded. Even when putting out, it is possible to perform only the same overhanging operation, and since the same overhanging and storing operations can be operated by the lever (22) of the operating unit (7), it is not necessary to get off from the combine (A). Streamline your work.
