Description

Detailed description of the invention (a) Industrial application field The present invention is a combine harvester in which grains after reaping and sorting are stored in a grain tank, and after the grain tank is full, the grains are placed on a ridge or the like. This invention relates to a storage device for a discharge auger that is carried out in pieces to a cargo platform such as a stopped trunk.

(B) Prior Art Conventionally, there has been a known technology in which a discharge auger is attached to a grain tank mounted on a combine harvester, and the discharge auger is made horizontally rotatable and vertically movable, and is stored on the armrest when stored. It has been done. For example, in 1977
This is as in Publication No.-5647.

(c) Problems to be Solved by the Invention An object of the present invention is to store the discharge auger 1 with a single touch after the grain removal operation is completed.

In the conventional technology, the operator manually rotates the discharge auger 1 horizontally not only when guiding the discharge auger 1 onto the truck bed, but also when returning the discharge auger 1 to the armrest 4 after unloading. Then rotate it to a position that seems to be above the armrest 4, then rotate it downward from that position and place it exactly on the armrest 4, but there is a slight error in the visual measurement, so While gradually making corrective rotations, it is finally placed on the armrest 4.

It is a time-consuming task to perform horizontal rotation, vertical movement, and move to the top of the armrest 4, which is a small metal fitting, by visual estimation.

The present invention automatically performs this storage operation.

(d) Means for Solving the Problems The objects of the present invention are as described above, and the configuration for achieving the objects will now be explained.

The discharge auger 1, which carries out the grains in the grain tank 5 mounted on the combine harvester, to the loading platform of a truck, etc., is configured to be rotatable vertically and horizontally.
When storing the armrest in the 4th position after the unloading is completed, by turning on the storage switch A, the discharging auger 1 is rotated horizontally with the tip raised, and then moved up and down from the upper position of the armrest 4. armrest 4
It can be stored in the following position.

(e) Effect of invention The effects based on the configuration of the present invention will be explained.

The operation of rotating the discharge auger 1 to a position above the truck bed or the like in order to determine the position for carrying out the grains is carried out by the operator while checking the position of the tip of the discharge auger 1. However, the loading platform of a truck or the like has a large area, and even if there is a slight positional deviation, it does not constitute an operational error. It is not a labor-intensive task.

However, as described above, the operation of returning the discharge auger 1 onto the armrest 4 after the completion of the carrying-out operation requires precision because the armrest 4 is small.

In the case of the present invention, the discharge auger 1 is returned to the storage position by a one-touch operation of turning on the storage switch, and then the discharge auger 1 is first rotated horizontally at a high position and placed above the armrest 4. When it rotates to the position, it stops exactly, and then it is lowered onto the armrest 4 and stored.

(f) Embodiment The object, structure, and operation of the present invention are as described above. Next, the structure of the embodiment shown in the attached drawings will be explained.

Figure 1 is a plan view showing the position of the combine harvester and discharge auger, Figure 2 is the same (side view), Figure 3 is a plan view showing the installation state of the horizontal rotation stop sensor 3, Figure 4 is the horizontal rotation stop FIG. 5 is a side view of the sensor 3, FIG. 5 is a side view of the armrest 4 and the vertical movement stop sensor 2, FIG. 6 is a side sectional view of the vertical auger 8, and FIG. 7 is a side view of the vertical auger 8. FIG. FIG. 3 is a circuit diagram of a sequence controller portion.

The overall configuration will be explained with reference to FIGS. 1 and 2.

The grain tank 5 of the combine is provided at the rear of the seat S where the operator sits, and the discharge auger l, which is the main part of the present invention, is also attached to the grain tank 5. This is where the center of horizontal rotation is located. In this position, when performing horizontal rotation, the seat S
Rotating the upper part of the seat S is dangerous as it may knock down the operator sitting in the seat S. Therefore, in this device, the discharge auger 1 does not rotate above the seat S, horizontally rotates to the unloading position counterclockwise in plan view, and returns on the same trajectory when storing next time. As a result, it is configured so that it can only rotate clockwise.

The range in which the discharge auger can be horizontally rotated is approximately 270 degrees excluding the seat S.

An armrest 4 and a vertical movement stop sensor 2 are provided on the upper surface of the threshing device of the combine, and a sensor 2 is provided to stop the horizontal rotation of the discharge auger 1 when it reaches the upper part of the vertical movement stop sensor 2. A horizontal rotation stop sensor 3 is provided.

The grain tank 5 of this embodiment can be rotated and opened for inspection of the power transmission device between it and the threshing device, and the vertical auger 8 also serves as the center of rotation of the grain tank 5. There is. The grain tank 5 is pivotally supported between the fuselage frame and the vertical auger 8 at the part of the five-part auger 12 that communicates with the lower auger 10 for the collection 21, and the upper part is supported by a reinforcing ring by the pivot ring 15 shown in FIG. It is pivotally supported on the outer periphery of 14.

Further, a drive unit for horizontal rotation of the discharge auger 1 is constructed on the outer periphery of the vertical auger 8.

That is, a driving bevel gear 13 meshes with the bevel gear 7, and the rotation of the driving bevel gear 13 rotates the vertical auger 8, thereby making it possible to rotate the discharge auger 1 attached to the upper part of the vertical auger 8. .

The horizontal rotation stop sensor 3, which is the main part of the present invention, is
It is fixed to the outer periphery of the base auger 12.

This will be explained with reference to FIGS. 3, 4, and 5.

A bracket is provided around the base auger 12, and horizontal rotation stop sensors 3a and 3b are provided, and the pushing piece 11 pushes the horizontal rotation stop sensor 3 to turn off the horizontal rotation stop sensor 3. It is to make it.

A switch operating piece 9 provided on the outer periphery of the vertical auger 8 comes into contact with the pushing piece 11 to operate it.

The horizontal rotation stop sensors 3 are provided on the left and right sides of 3a and 3b, with the armrest 4 being one end of the horizontal rotation stop sensor 3.
The ejection auger 1 is rotatable through an angle ranging from 2 to 2 degrees.
This is because a stopper device is also required at the other end rotated through an angle of 70 degrees.

That is, it is a stopper device when the horizontal rotation stop sensor 3a returns to the position of the armrest 4, and it is a stopper device when the horizontal rotation stop sensor 3b is rotated by 270 degrees, which is the maximum angle.

A switch operation piece 9a for operating the horizontal rotation stop sensor 3a and a switch operation piece 9b for operating the horizontal rotation stop sensor 3b are provided, and the switch operation pieces 9a and 9b are connected to each other. The angle is approximately 90 degrees.

With the configuration as described above, rotation passing through the seat S is impossible.

With the above configuration, the following effects are achieved.

When rotating the discharge auger 1 for carrying out grains, operate the vertical movement manual switches 21a and 21b,
The operator lifts the discharge auger 1 mounted on the armrest 4, then operates the horizontal rotation manual switches 20L and 20R to horizontally rotate the discharge auger 1 and position it on the loading platform of a truck or the like.

Next, when storing the discharge auger 1, the sequence controller is activated by turning on the storage switch A, and after first positioning the discharge auger 1 at a sufficient height, it rotates horizontally. . At the end of the horizontal rotation, the switch operation piece 9a comes into contact with the horizontal rotation stop sensor 3a, thereby stopping the horizontal rotation of the discharge auger 1.

Then, the vertical movement is started, and the discharge auger 1 is lowered into the armrest 4 and fixed therein.

This series of storage operations is performed continuously by turning on the storage switch A.

Furthermore, if automatic storage is enabled by a one-touch operation of the storage switch A, there is a possibility that the discharge auger 1 may pass over the seat S during return rotation and come into contact with the operator sitting on the seat S, causing an accident resulting in injury or death. However, in the case of the present invention, the safety of the operator can be protected by rotating the seat S so that it does not pass over the seat S.

(G) Effects of the Invention Since the present invention is configured as described above, it has the following effects.

First, when storing the discharge auger 1 as in the past, the operator must supervise the armrest 4 and the discharge auger 1 to ensure that they are correctly aligned and stored. Since there is no need to operate the combine harvester while moving, the operator can move on to running the combine by pressing only the storage switch A after grain removal, and can store the discharge auger 1 at the same time as the combine harvester is running. It is possible.

Second, since the discharge auger 1 rotates horizontally with its tip raised diagonally, there is no fear that the grains remaining at the tip of the discharge auger 1 will spill out due to the rotation of the discharge auger 1 when it is retracted. It is.
