Description

[Detailed description of the invention] The present invention collects the harvested grain trunks in a grain trunk cutting device used when harvesting the grain trunks of soybeans, etc. The purpose of the present invention is to provide a device for collecting grain trunks that allows the grains to fall.

The present invention is a structure of a concentrating device attached to the grain trunk reaping machine, and an embodiment thereof will be explained with reference to the drawings. This machine is used by moving forward, guiding grain trunks planted on the ground with a guiding rod 3 at the tip, harvesting them with a rotary blade 4, moving the harvested grain trunks with a grain transporting device 5, and collecting them on a loading platform. 6. Gather on top.

The driving force of the engine 1 is used to drive not only the wheels 7 but also the rotary blade 4 and the grain transport device 5.

Conventionally, the grain trunks of the legumes harvested in this manner did not have a collection platform and were dropped backwards as the reaping device moved forward.The cropped legumes were scattered on the surface of the field, making it difficult to accumulate them. It took.

The present invention eliminates such trouble by installing a grain trunk collecting device on the vehicle platform to accumulate the grain trunks and, if necessary, to drop the collected grain trunks all at once onto the field.

In FIG. 3, the focusing device 6 stands out from the front wall surface A1, the bottom surface B1, and the rear wall surface C, and the front wall surface A and the bottom surface B are pivotally supported by a hinge 9.

Describing the structure of the focusing device 6 in detail, P, Q, and R are support points that support the entire focusing device 6.

Each of the wall surfaces A, C and the bottom surface B has a receiving material on the back surface, which controls the focusing device 6 for dropping the bundled grain trunk.

The receiving material for wall surface A is 17, the receiving material for bottom surface B is 11, and the receiving material for wall surface C is 15.

The receiving material 17 and the receiving material 11 are connected by a hinge 9, and the wall surface A and the bottom surface B are configured to be flexible and expandable.

An L-shaped lever 10 is supported at one end by a hinge 9 below the receiving member 11 and is supported at a fixed support point R via an elongated hole 13 provided between the edges of the L-shape.

A fulcrum S is provided at the other end of the L-shaped lever 10 and engages with an elongated hole 16 provided in a receiving member 15 of the wall surface C.

The end of the receiving material 15 extends from the back surface of the wall surface C to a fixed support point R.
is rotatably engaged with.

The hinge 9 is provided with an operation frame 8 (dotted chain line).

Next, to describe the operating situation of the present invention along with its function, in order to drop the grain trunks accumulated on the focusing device 6, pull the focusing lever 8 toward you near the handle 2 shown in FIGS. 1 and 2. (Then, the hinge 9 is pulled by the focusing lever 8 and changes from the state shown in FIG. 3 to the state shown by the imaginary line in FIG. 4.

That is, the hinge 9 in FIG. 3 moves in the direction of the arrow, the front wall surface A rotates around the support point P, and the bottom surface B rotates around the support point Q while shifting along the elongated hole 12. As shown in the figure, surfaces A and B form a straight line.

At this time, the receiving material 11 on the bottom surface B slides along the elongated hole 12 at the support point Q and is displaced to the other end of the elongated hole 12.

One end of an L-shaped lever 10 is pivotally supported on the hinge 9, and as the hinge 9 moves, the relationship between the elongated hole 13 provided on one side of the L-shaped lever 10 and the support point R changes, and the L-shaped lever 10 changes. stands up.

The lever 14 serves to prevent the fixed support points Q and H from displacing each other without moving at all, and is installed so that the engaging members to the support points Q and R will not fall off the support point QXR.

The fulcrum S at the other end of the L-shaped lever 10 is the supporting member 1 of the wall surface C.
5 is moved to rotate the wall surface C around the support point R.

In this way, the L-shaped lever 10, the receiving material 17 on the wall surface A, and the bottom surface B
By skillfully combining the support material 11 of the wall surface C and the support material 15 of the wall surface C, the wall surface A and the bottom surface B are displaced on an inclined straight line with the support points P and Q as axes, and the support material 15 of the wall surface C is disposed on the hinge 9. It moves along the two sides of a pivoted L-shaped lever 10, tilts the wall surface C below the bottom surface B, and allows the grain trunks gathered on the bottom surface B to fall all at once.

As soon as the grain trunk falls, the focusing lever 8 is pushed to return the focusing device to form a loading platform, or the hinge 9 is pushed back by the action of the spring, and the relationship between the wall surface A and the bottom surface B becomes linear. It becomes a bent shape and the wall surface C
As the L-shaped lever 10 is changed in position, it returns to its original state as shown in FIG.

Thus, the focusing work can be continued.

As is clear from the above description, the present invention is attached to a grain trunk reaping device, and includes a mechanism for tilting the bottom surface of a grain trunk collection east loading platform having walls on the bottom and front and rear sides, and an L having one end pivotally supported on the bottom surface. This grain concentrator has a fulcrum on each side of the L-shaped lever, and a wall that moves along the L-shaped lever. The rear wall surface is moved by the action of the elongated hole, and the rear wall surface moves below the bottom surface, and as the bottom surface inclines, the rear wall surface is reversed, allowing the grain trunk to fall.

Further, as the bottom surface is displaced, the front wall surface is joined by a hinge, so the front wall surface tilts about the fixed rotation support point, and the front wall surface and the bottom surface tilt in a straight line.

In addition, the operating rod that causes this tilting operation was installed at the hinge between the front wall surface and the bottom surface, and was supported by the rotation support point of the front wall support and the fixed rotation support point provided in the elongated hole of the bottom support material. With a single touch of the operating stick, the loading platform can be dropped or returned to its original position, making it possible to accumulate grain trunks that were previously harvested and left in pieces. It is extremely effective for post-processing such as drying and threshing.
