Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reduces the loss of the No. 3 scattering by a suction dust collector when the material to be processed which is inherited from the handling cylinder chamber, processed by the processing cylinder and discharged is a dry material. The present invention relates to a suction dust control device for a thresher.

[0002]

2. Description of the Related Art Conventionally, a suction port of a suction dust collector is connected to one side of a sealed dust collecting chamber provided above the end of a swing sorting device so as to communicate with the handling chamber. A dust outlet on the end side of the extending processing cylinder is opened laterally to the other side of the dust collection chamber facing the suction port of the suction dust collector, and the suction port and the rocker are shaken from the upper side of the dust outlet. In the thresher configured to be able to discharge the object to be processed toward the upper end side of the dynamic sorting device, if the object to be processed is a wet material, the object to be processed discharged from the dust outlet will be lost due to the third scattering. As with most, it is well sorted by the suction air.

As disclosed in Japanese Utility Model Laid-Open No. 61-125249, it is known that an adjusting plate is swingably adjustable on the discharge port side of the processing cylinder in front of the suction port of the suction dust collector. ing.

[0004]

However, in the conventional structure like the former, when the object to be processed is a dry material, the object to be processed discharged from the dust outlet is delicately sucked by the suction dust collector. There was a problem that it became easier and the loss due to the scattering of the third mouth increased.

The latter type of conventional structure is intended to process the processing cylinder that has been sent out from the rocking / sorting device and to control the opening of the adjusting plate according to the load of the processing cylinder. However, it cannot be adjusted according to the dry material to be processed.

[0006]

SUMMARY OF THE INVENTION The present invention solves such a problem and can effectively reduce the loss of scattering of the No. 3 mouth of the object to be processed, which is a dry material. A suction port of a suction dust collector is connected to one lateral side of the closed dust collecting and sorting chamber provided above the end side of the sorting device, and the end side of the processing cylinder extending in communication with the handling cylinder chamber extends. The dust outlet is opened laterally and laterally of the dust suction sorting chamber facing the suction port of the suction dust collector, and is directed from the upper side of the dust outlet toward the suction port and the upper end side of the swing sorting device. In a thresher configured to be capable of discharging the object to be processed, a first point at the upper end of the dust outlet,
The second point at the lowermost end of the suction port is connected to the third point on the uppermost surface of the dust-sorting chamber that is in an upward direction from a straight line and is in the vicinity of the first point, and the third point is lower than the suction port. The dust guide plate is pivotally supported at the third point on the straight line connecting to the fourth point on the lateral upper side of the swing selecting device in the vicinity of the two points, and the dust guide plate is also provided. Is configured so that the inclination can be changed and adjusted above the straight line.

[0007]

Therefore, when the object to be processed which is inherited from the handling cylinder chamber and processed by the processing cylinder is discharged from the dust outlet into the dust sorting chamber, the first point and the second point are provided from the upper side of the dust outlet. While being discharged to the lower side along the straight line connecting the points, the light dust among them is sucked into the suction port and discharged outside the machine as the third object, and the heavy object such as the second object swings. Although it will be swing-sorted by being discharged onto the sorting device, in the case of dry material, the dust guide plate should be tilted along the direct line connecting the third point and the fourth point. If you leave it, the dry material to be processed that is discharged from the upper side of the dust outlet is likely to be immediately sucked to the suction port side. Forcibly guided to 2
It is possible to guide effectively so that dust etc. are not easily sucked. Also, in the case of wet material, if the dust guide plate is tilted upward, the wet material can be treated like the conventional type. Is well sorted by dust suction sorting guide.

Above the dust collection chamber 2, a straw chain 17 extending above the straw cutter device B is extended.

A suction / dust collector 3 communicating with a suction port 3a is provided on the left lateral side of the dust collecting / sorting chamber 2 so as to communicate with the end side of the handling barrel chamber 4 in the axial direction. A plurality of jumping blades 19 are mounted on the outer periphery of the end of the processing cylinder 5 which is parallel to the axial direction of the processing cylinder 11, and a plurality of jumping blades 19 are attached to the end of the processing cylinder 5 which rotates in the same direction as the processing cylinder 11. A dust outlet 6 is opened in the upper part of the right lateral side of the dust collecting and sorting chamber 2 on the left lateral side, and a screening net 20 is provided on the outer periphery of the left lateral side in the middle of the processing cylinder 5. Configure.

As shown in FIG. 1, the dust discharge port 6 is opposed to the suction port 3a, and the first point P _{1 at} the upper end of the dust discharge port 6 and the second point at the lowermost end of the suction port 3a. Above the straight line S ₁ connecting the point P ₂ and above the third point P _{3 on} the uppermost surface of the dust collection chamber 2 in the vicinity of the first point P ₁ and lower than the suction port 3a, A straight line S connecting to the fourth point P ₄ on the upper lateral side of the swing selecting device 1 in the vicinity of the second point P _2.
The upper part of the dust guide plate 7 located above ₂ is fixed to a fulcrum shaft 21 which is erected at the portion of the third point P ₃ , and a rotary arm 22 extends upward from the end of the fulcrum shaft 21. A cylindrical body 24 is fixedly installed at a portion of the machine wall 23 near the upper side of the suction and dust collector 3, and a tip end of a supporting rod 25 slidably fitted into the cylindrical body 24 is provided.

When the material to be processed is a dry material, the dust guide plate 7 is tilted along the straight line S ₂ as shown in FIG. 1 while loosening the set bolt 26 and pulling out the supporting rod 25. If so, the dry material to be processed discharged from the upper side of the dust discharge port 6 is likely to be immediately sucked to the suction port 3a side, but at the discharge position, the dust guide plate 7 swings. It can be forcibly guided to the upper side of the sorting device 1 so that the second object or the like can be effectively guided so as not to be sucked easily. In the case of a wet material, the set bolt 26 is loosened to deepen the support rod 25 deeply. When pushed in, the dust guide plate 7 can be largely tilted upward as shown by the arrow B, so that the object to be treated of the wet material is satisfactorily sorted in the dust collection chamber 2 as in the conventional case. Will be.

It should be noted that, depending on the state of the dry material or the wet material, if the dust guide plate 7 is slightly tilted from above the straight line S ₂ to the upper side thereof, the dust guide plate 7 can be adjusted to suit each state.
