Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention rotates a Glen tank mounted on a combine to a side for inspecting a drive unit formed between the Glen tank and a threshing device. The present invention relates to a close contact structure between a fried-grain barrel and a Glen tank in the case where the above is possible.

(B) Conventional Technology Conventionally, there has been known a technology in which a Glen tank mounted on a combine can be rotated to inspect a drive shaft between the combine and the thresher.

For example, it is as in JP-A-61-43944.

(C) Problems to be Solved by the Invention However, in the conventional technique, when turning to the side of the Glen tank, both are separated from the spout of the fried cylinder and the joint of the Glen tank. However, when the Glen tank is returned to the original position again, the close contact state of the portion is deteriorated, and the grains that are vigorously ejected from the throwing-out portion are ejected from the portion.

In order to prevent this, a seal plate is attached to the flange portion of the spout, but the seal plate receives a rubbing force and breaks when the Glen tank travels.

The present invention prevents the seal plate from breaking and the adhesion of the joint portion from being deteriorated, and prevents the leakage of the grain from the throwing port.

(D) Means for Solving the Problems The object of the present invention is as described above, and the configuration for achieving the object will be described below.

The threshing device D and the grain tank 1 can be separated at the throwing port 3 of the fried cylinder 2 standing upright on the side of the threshing device D and the opening 1d of the grain tank 1 to which the throwing port 3 is fixed. In a configuration in which the grain tank 1 is horizontally rotatable in the side opposite to the threshing device D, centering on a vertical auger 6 for discharging, which is arranged behind the fried cylinder 2, in the rear portion of the grain tank 1. The recessed portion 1a is provided, and the recessed portion 1a is configured to be in close contact with the throwing port 3 and the inclined surface 1b is provided from the throwing port 3 toward the recessed portion 1a at an angle α that is inclined with respect to the front-back direction in plan view Surface 1b is the spout 3 and the Glen tank 1
It is intended to be a close contact surface with.

(E) Action of the device With the configuration of the present invention, the following actions are achieved.

When rotating the Glentank to the side, the corner on the rear threshing device side, which is square in plan view, rotates in the shape of the largest arc, and this part passes the front surface of the throwing port 3. To do.

In the present invention, the concave portion 1a is formed in the Glen tank 1 behind the portion closely contacted with the spout 3, and the recessed portion 1a is formed so as to move backward from the joint surface with the spout 3 to pass the front surface of the spout 3. The corner portion is configured so as not to come into contact with the spout flange 3a of the spout 3.

Further, since the throw-out flange 3a is linearly formed in the front-rear direction only by forming the concave portion 1a in the portion, the portion in contact with the rear end of the throw-out flange 3a forms the front-rear surface. After all, the two joint surfaces will be rubbed together.

In the present invention, the rear surface of the portion that comes into contact with the spout flange 3a is inclined surface 1 in the direction substantially facing the pivotal support portion of the Glen tank.
By adopting b, the corner portion of the rear end of the joint portion of the spout flange 3a is eliminated, and both joint surfaces are not in a rubbing state, and they are jointed substantially at the same time.

By forming the concave portion 1a and the inclined surface 1b in this way, the corner of the Glen tank passing through the portion of the spout 3 can be eliminated, and the seal plate 5 is not scratched and broken by the corner. is there.

The arrangement of the Glen tank 1 will be described with reference to FIG.

A threshing device D is arranged on the left side in the traveling direction, and the Glen tank 1 is arranged long in the front and rear so as to be parallel to the threshing device D. A seat S is arranged in front of the Glen tank 1,
An engine room is formed under the seat S.

In the present embodiment, the vertical auger 6 also serves as the pivotal support portion of the Glen tank 1. The vertical auger 6 rotates at its upper end in order to horizontally rotate the discharge auger 8 which is vertically rotatable.

Further, the Glen tank 1 is rotatable to the side position 1'by using the vertical auger 6 as a pivot shaft.

A lower auger 7 is arranged below the Glen tank 1, and a bearing auger 10 is formed in a portion where the lower auger 7 projects rearward of the Glen tank 1.

The bearing auger 10 is fixed to the Glen tank 1, and when the Glen tank 1 rotates, the portion fitted to the vertical auger 6 rotates, and the vertical auger 6 side serves as the bearing support side. Of. On the contrary, when the vertical auger 6 rotates to horizontally rotate the discharge auger 8, the Glen tank 1 is stopped, and therefore the vertical auger 6 rotates at the portion fitted to the bearing auger 10. is there.

Similarly, a bearing cylinder 11 is projected above the Glen tank 1 from the Glen tank 1, and the bearing cylinder 11 can rotate around a support cylinder 13 projected from the fuselage side of the combine.

A vertical auger 6 is loosely fitted and supported inside the support cylinder 13.

A discharge auger 8 is pivotally supported on the upper end of the vertical auger 6 so as to be vertically rotatable.

Next, the embodiment shown in FIGS. 1 and 2 will be described.

The threshing device D is longitudinally arranged on the left side in the traveling direction of the combine, and the grain tank 1 is arranged in parallel with the threshing device D on the right side in the traveling direction.

The right side of the rear portion of the Glen tank 1 in the traveling direction is cut out to form a cutout portion 1c, and a vertical auger 6 is formed in the cutout portion 1c.
Is installed upright, and the vertical auger 6 is the Glen tank 1
Is the center of rotation.

The frying tube 2 is erected between the threshing device D and the grain tank 1 in front of the vertical auger 6.

A throwing port 3 is provided at the upper end of the fried food barrel 2, and a throwing port flange 3a is vertically attached to the side of the grain tank 1 of the throwing port 3. A seal plate 5 is interposed between the spout flange 3a and the opening 1d of the Glen tank 1.

The seal plate 5 may be attached to the side of the spout flange 3a or may be attached to the opening 1d side of the Glen tank 1.

In the Glen tank 1 behind the throwing port 3,
The concave portion 1a is provided in the portion facing the threshing device D.

The recessed portion 1a may be provided all over the height of the Glen tank 1, or may be provided only in the upper portion where the spout flange 3a is provided.

In the embodiment shown in FIG. 2, an inclined surface 1b having an angle α from the wall of the protrusion 1e shown in FIGS. 2 and 3 is formed toward the recess 1a.

In the embodiment, the inclined surface 1 is formed from the central portion of the spout 3.
b, and the throw-off flange 3a is formed in a V shape in a plan view.

Also, the angle α is generally oriented toward the vertical auger 6, which is the pivotal support.

In the embodiment of FIG. 3, the vertical auger 6 is arranged at the rear end of the grain tank 1 without forming the cutout portion 1c in the portion where the vertical auger 6 is arranged. Further, an inclined surface having an angle α'provided from the protrusion 1e toward the concave portion 1a is formed from the front end position of the throwing port 3, and the entire casting port flange 3a has the inclined surface 1a.
It is configured to abut b.

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

First, since the Glen tank 1 is configured to rotate horizontally in the direction opposite to the threshing device D with the vertical auger 6 as a pivot point for inspection and repair, the discharge auger 8 arranged above the vertical auger 6 is arranged. Does not interfere with the horizontal rotation of the Glen tank 1.

Moreover, since the weight of the Glen tank 1 can be received by the vertical auger 6, it is not necessary for the operator to rotate the Glen tank 1 while supporting the weight of the Glen tank 1.

Secondly, a seal attached to the spout flange 3a of the spout 3 or the opening 1d of the Glen tank 1 is provided at the corner of the rear end of the Glen tank 1 on the threshing device D side when the Glen tank 1 rotates. There was a case where the seal was scratched by the portion, or the seal attached to the opening 1d side of the Glen tank 1 was scratched and torn at the rear end portion of the spout flange 3a.
In the present invention, since the concave portion 1a is provided at the corner of the rear end of the Glen tank 1, the concave portion 1a is in the retracted position, so that the Glen tank 1 can be thrown even when the Glen tank 1 is rotated about the pivot portion. Since the seal on the mouth flange 3a side is not contacted, and the rear end of the spout flange 3a side and the opening 1d side are joined by the inclined surface 1b, finally the surfaces of the inclined surface 1b are joined substantially at the same time. Therefore, the rubbed state did not occur and the seal did not break.

Thirdly, in the past, the spout flange and the opening were in close contact with each other in a rubbing state and stopped in the same parallel posture,
Even though the seal was pressed to some extent, it eventually left a parallel gap.

On the other hand, in the case of the present invention, since the surfaces of the thrower 3 and the opening 1d side which sandwich the seal are substantially orthogonal to the rotation arc of the Glen tank 1, the seal is pressed to lift the grain. Since the tube 2 is brought into close contact with it in a pressed state, the possibility that a gap is formed in the joint portion is reduced, and the leakage of the grain from the portion is reduced.
