DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a plurality of dust-feeding plates arranged side by side along the axis of a handling cylinder in a handling chamber for supporting a handling drum. The present invention relates to a dust valve structure of an axial flow type combiner in which the dust plates are connected in an interlocking manner such that the angle intersecting with the axis of the handling cylinder can be changed.

[0002]

2. Description of the Related Art Conventionally, in a dust valve structure of this type of axial flow type combiner, as disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 6-237634, each dust-feeding plate is provided with a handle shaft. The tilt angle is set to the same angle with respect to the core, the tilt angle can be changed to increase or decrease the feeding action, and all the dust feeding plates maintain the same tilt angle Was to be configured.

[0003]

On the other hand, on the first half side of the handling room, that is, on the upper side in the direction of transporting the threshing product, the amount of threshing product supplied into the handling room is large. If the staying time is long, there is a possibility that clogging may occur because there is some processed material to be supplied later. The feed angle of the dust plate of the dust valve is set so that the dust is sent backward at a relatively high speed. However, in this case, there is a high possibility that the threshing treatment is insufficient, or that the paddy is stuck in the straw waste and discharged out of the machine, and the collection efficiency is low. The present invention has been made in view of the above-mentioned circumstances, and it is possible to suppress the sting of paddy and the like, and to perform the threshing process sufficiently, but to prevent the clogging of the threshing processed product from occurring. The purpose is to provide a dust valve structure.

[0004]

According to the present invention, there is provided a dust valve structure for an axial flow type combiner according to the present invention.
In the handling room that supports the handling cylinder, a number of dust-feeding plates are arranged side by side along the handling cylinder axis, and the angle of each dust-feeding plate that intersects with the handling cylinder axis is integrated. In the dust valve structure of the axial flow type combine, in which each dust plate is linked and connected by a connecting rod, the dust plate at the lower side in the threshing process transfer direction along the axis of the handling cylinder axis. angle, and sets the angle to allow Okuchiri for plate member by <br/> remote treated transfer of the upstream side of each Okuchiri
Arm for projecting the plate for each dust sending plate
Pivotally connected to the connecting rod at a pivot point at the portion,
From the swinging shaft of the lower dust-feeding plate to the lower dust-feeding plate
Link length to the pivot point in
Pivot point on the plate for dust sending that is on the upper side from the pivot axis of the plate
It is characterized in that the link length up to the place is set equal . The operation and effect of this characteristic configuration are as follows.

[0005]

In other words, the angle of the lower dust-feeding plate body with respect to the handling cylinder axis in the threshing process transfer direction along the handling cylinder axis direction is greater than that of the better dust-feeding valve plate body. Is set at an angle that allows the threshing process to be performed in the handling room in the handling room, so that threshing is sufficient. In the handling room, the transfer speed of the processed material is increased in the direction of transfer of the processed material. Therefore, even if the pressure increases and the processing material is increased, it is possible to increase the possibility that the processing material will be sent to the lower hand, and it is possible to prevent the processing material from being clogged between the handling cylinder and the receiving net.

[0006]

As a result, the threshing operation of the processing chamber in the handling room in the direction of transfer of the processed material is sufficient because the residence time of the processed material can be increased. Nevertheless, the transfer speed of the processed material is increased in the direction of transfer of the processed material in the handling room. The processed material comes out easily and is transported, so that clogging is easily avoided.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an axial flow type combine threshing apparatus. In this threshing apparatus, a handling room 1 for introducing a harvested grain culm as a threshing processed material conveyed and supplied from a pre-cutting processing unit on the left outside the figure is formed in the upper part of the case, and a sorting unit is provided below the handling room 1. 2 is provided, and a receiving network (concave) 3 is provided to supply the processed material from the handling room 1 to the sorting unit 2 in a leaking manner.

A single handling cylinder 4 is supported in the handling chamber 1 horizontally in the front-rear direction, and a spiral handling tooth 5a is attached to the outer peripheral surface of the handling cylinder 4 over substantially the entire length in the front-rear direction. The independent handling teeth 5b are attached at an appropriate pitch in the circumferential direction, and a threshing valve 6 for guiding the threshing material flowing in the circumferential direction of the handling cylinder with the rotation of the handling cylinder 4 in the axial direction X of the handling cylinder is attached to the handling chamber top plate. 7.

The sorting section 2 is provided with an oscillating sorting case 2 a, a wind sorting box 2 b, a first-item collecting screw conveyor 8, and a second-item collecting screw conveyor 9, and a process supplied by leaking from the receiving net 3. The sifting and wind sorting processes are performed while the material is rocked backward by the rocking sorting case 2a, and the grains are sent from the screw conveyor 8 for collecting the first material to a Glen tank (not shown). The second product is returned from the second product recovery screw conveyor 9 to the front of the swing sorting case 2a via a reduction device (not shown).

As shown in FIG. 1 to FIG.
Are pivotally supported on the top plate 7 by a support shaft 11 so as to be swingable around a vertical axis centering on a substantially central portion in a longitudinal direction of a guide action surface of each of the plurality of dust-feeding plates 10 #. ing. One end of each dust-feeding plate 10 is pivotally supported by an interlocking rod 12 along the front-rear axis X direction so as to be swingable about the vertical axis. A swing arm 13 is pivotally attached to the support shaft 11 of the front end of the dust-feeding plate 10 # by the outside of the threshing case. This swing arm 13 is engaged with and interlocked with a pin 16a of a top member 16 screwed to a screw shaft 15 that is rotated forward and reverse by a driving device 14 using an electric motor. 10 ° is interlocked with an interlocking rod 12 so as to be swingable.

More specifically, as shown in FIG. 3 to FIG. 5, when the feed speed is the slowest, the fineness of the dust sending plate 10 in the processing object transfer direction, that is, in the front-back direction. In the case of a garment, the intersection angle of the workpiece transfer guide surface with respect to the handling cylinder axis X is set to an angle close to a right angle, and a lower garment in the workpiece transfer direction is better than a better garner. The angle is set at an angle. In other words, the connection point to the support shaft 11 which is the swing center of each dust plate 10 # is
Although it is set at almost the center of the guide action range of the processed object transfer guide surface of all the dust feeding plates 10 #, the pivoting point 17 to the interlocking rod 12 is configured to transfer the workpiece in the processed object transfer direction. The length L1 of the pivoting arm 10b of the dust plate 10 protruding from the edge of the dust plate 10 is set to the length of the interlock rod 12 of the dust feed plate 10 in the downstream direction in the processing object transfer direction. Since the length L2 of the pivoting arm 10c protruding from the portion is set shorter than the length L2, the length L of the link connecting the pivoting point 17 to the interlocking rod 12 and the pivot 11 is set to each of the dust-feeding plates. Despite the fact that they are equal at 10 °, the dust carrier plate 10 of the lower arm always has a larger handle axis X than the dust carrier plate 10 of the upper arm, even though they are equal at 10 °. The angle is maintained at an inclined posture. That is, even if the driving device 14 is appropriately operated to change the angle of the workpiece transfer guide surface of the dust transport plate 10 with respect to the workpiece transport direction, the dust transport plate that is always lower in the workpiece transport direction is set. 10 is maintained and set at an angle posture in which the handling cylinder axis X having a higher processing object transfer function is tilted aside than the well-done dust-feeding plate body 10. FIG.
As shown in FIG. 5 to FIG. 5, the pivoting position of each dust-supply plate 10 on the lower side is changed so that the pivotal position of the lower-side dust-supply plate 10 with respect to the interlocking rod 12 can be changed in three places in the front-rear direction. The arm 10c is provided with three holes 10d for pivotal support. Thereby, it is possible to set a plurality of types of angle setting of each lower dust-supply plate 10 with respect to each upper dust-supply plate 10, and in the structure of FIGS. It is also possible to make the angle of the entire dust-feeding plate 10 with respect to the processing object transfer direction constant.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the structure shown in the attached drawings.
