Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a No. 2 return device for returning the No. 2 items remaining after sorting to the threshing section for re-sorting in a threshing machine.

In an independent mobile or fixed threshing machine that does not have a combine threshing machine or reaper, the grains threshed by the handling drum in the handling chamber fall through the mesh of the handling chamber receiving net, and are then transferred to the sorting device. are sorted and collected. On the other hand, the processed materials generated during threshing, such as straw waste, hooks, and ear cuts, fall from the dust outlet in the handling room and are sorted by a sorting device, where some grains are collected and light straw waste is removed. etc. are sucked up by a dust suction device and discharged outside the machine. The processed material that remains as a result of sorting in this way is called the second material, and after this second material falls onto the conveyor at the bottom of the sorting room and is completely conveyed, it is placed on the second hoist at the end of the conveyance. The grain is scraped up by a grain machine and lifted up and transported inside the No. 2 reduction cylinder. The lifted and conveyed second material is then returned to the handling chamber, where it joins the material to be processed that is moving near the return port, where the sorting is repeated.

32 is a No. 2 grain lifting machine fixed to the end of the shaft protruding outside the frame of the No. 2 spiral conveyor 31, and is covered with a shell 33 so as to scrape up the No. 2 grains that can be conveyed by the No. 2 spiral conveyor 31. It is composed of One end of a No. 2 reduction cylinder 34 is connected to the discharge port of the barrel 33, and the other end of the No. 2 reduction cylinder 34 is connected to the rear plate 1, which is the rear end of the upper part of the space 15.
It is connected to a No. 2 reduction port 35 opened at the upper end corner of 3. By doing so, the No. 2 grains are lifted up and conveyed inside the No. 2 return cylinder 34 by the No. 2 grain lifting machine 32, and are returned to the space 15 yen through the No. 2 return port 35.

Therefore, to explain the structure inside the space 15, the upper part of the space 15 and the inside of the handling chamber 3 are communicated with each other through an opening 36 extending over the entire length of the handling chamber 3. Almost half of the direction is vertically blocked by a guide plate 37 that spans the entire length. This guide plate 37 is arranged so that it gradually becomes lower from a position approximately at the same height as the lower edge of the second return opening 35 toward the lower edge of the opening 36. 2 into the handling chamber 3. Moreover, in the upper part of the space part 15 and in the center of the opening where the guide plate 37 is provided, there is provided an arc-shaped No. 2 reduction guide 38 for bringing the No. 2 into contact and changing direction. Further, at the upper part of the space 15, a second flow plate 39 is provided which protrudes from the lower edge of the second reduction port 35 into the space 15 so that its tip becomes lower. It is configured to guide No. 2 returned from 35 and guide it through the space 15 to the front part of the sorting chamber 4.

At the lower end of this second flow plate 39, there is a middle plate 40 formed in an arc shape along the top edge of the tooth 16.
are joined, and a part of the space 15 and the handling chamber 3 and the sorting chamber 4 are blocked off from each other in the front and back. Reference numeral 41 denotes a zigzag-shaped separating plate located in the second falling passage on the handling chamber 3 side formed between the middle plate 40 and the rear plate 13 and joined to the lower end of the guide plate 37. The structure is such that the second part is brought into contact with the second part to loosen the lump.

On the other hand, inside the culm removal chamber 5, there is provided an endless belt 42 for transporting the threshed husks, that is, waste straw, which is carried over from the endless belt 19, and a waste straw conveyed by the endless belt 19. A straw cutter 43 that cuts the waste and discharges it to the field, and a dust suction device 45 that sucks light straw waste etc. from the material being sorted on the sorting body 27, 28 and discharges it from the dust outlet 44 to the outside of the machine. It is arranged.

In the threshing machine configured as described above, the husk 18 is conveyed while being held at the root by the endless belt 19 and the clamping rod 20.
The tip of the grain is handled and threshed with a barrel 1T, and the threshed waste straw is conveyed on an endless band 42, cut with a straw cutter 43, and released into the field. The threshed grains fall onto the sorting body 25 through the mesh of the receiving net 9 in the handling room, and are placed on the swinging shelf 2.
After being sorted by the shaking of No. 4 and the sorting wind from Karakino No. 29,
It falls onto the No. 1 spiral conveyor 30 and is conveyed and collected.

On the other hand, the straw waste, ear scraps, snails, and other processed materials generated during threshing are discharged from the dust outlet 26 and fall onto the sorting body 2T, and the swinging shelf 24 moves the sorting bodies 27 and 28. While being conveyed in sequence, they are sorted by this rocking motion and the sorting wind from the winnowing machine 29. Some of the grains are recovered by this sorting, and light straw waste, dust, etc. are sucked up by the dust suction device 45 and discharged from the dust outlet 44 to the outside of the machine. The material that remains after being sorted in this way is called No. 2, and is placed on the No. 2 spiral conveyor 31.
After falling upward and being conveyed, the grains are lifted and conveyed into the second reducing cylinder 34 by the second grain lifting machine 32 and discharged into the space 15 through the second reducing port 35. Of the 2 discharged items, the lighter one is 2.
After being flown to a location far away from the number 35 force 1 and guided into the handling chamber 3 by the number 2 guide plate 3T, it merges with the material to be treated in the handling chamber 3 and the sorting is repeated. In addition, the No. 2 lump is discharged from the No. 2 reduction port 35 and is immediately removed from the No. 2 guide plate 3.
7, and while falling through the handling room side falling path between the middle plate 40 and the rear plate 13, it is +1 by the separating plate 41, and then merges with the processed material and is repeated for sorting. Furthermore, when handling wet No. 2, if wet No. 2 accumulates on the No. 2 guide plate 3T, the No. 2 discharged from the No. 2 reducing port 35 is guided to the No. 2 sink plate 39 and left in the space. Four forces are passed through the section 15 to the sorting chamber 4. In this case, since the No. 2 flow plate 39 is inclined, the No. 2 flow plate sliding thereon is given an initial velocity and is returned to the starting end of the sorting chamber 4. - At this time, the number 2 is guided by the number 2 return guide 38. The No. 2 material led to the sorting chamber 4 joins the material being sorted in the swinging shelf 24, and is sorted or repeatedly heated.

In the threshing machine 1 provided with this second sink plate 39, by removing the second sink plate 39, the entire frame 2 can be used as it is as a frame for a double-barrel type threshing machine with a processing barrel. FIG. 4 is a side sectional view corresponding to FIG. 2 of a double-acting threshing machine that shares a frame with a single-barrel threshing machine, and shows the processing chamber 5, which is the part excluding the second sink plate 39.
A processing cylinder 52 having approximately the same length as the processing cylinder 17 and having a large number of processing teeth 51 on the circumferential surface is mounted on the shaft, and a partition plate 53 is provided between the processing chamber 50 and the processing chamber 4 and the space 15. and a processing chamber receiving screen 54.

Further, the second reduction port 35 is opened to the processing chamber 50. The rest of the structure is the same as the single-barrel threshing machine 1, so a description thereof will be omitted, and the function of the multi-barrel threshing machine is the same as that of conventionally known ones, so the explanation thereof will be omitted. By doing this, the frame can be used in common for both the single-barrel type and the double-barrel type, thereby reducing production costs and simplifying inventory management.

As is clear from the above description, according to the present invention, in the second reducing device of a threshing machine, a handling chamber 4. Frame side plate 1
A second guide plate 37 extending in the axial direction of the handling barrel 1T from approximately the same height as the lower end edge of the second reducing port 35 and blocking approximately half the width of the space 15 is installed above the four-way space 15. 36
A second flow plate 39 is provided below the second guide plate 37, the second flow plate 39 is inclined such that its tip becomes lower from the lower edge of the second reduction port 350 into the space 15. By providing this, most of the No. 2 discharged from the No. 2 reducing port 35 is guided by the No. 2 guide plate 37 and guided into the handling chamber 4, where sorting is repeated, so that good sorting performance can be obtained. Of course, when No. 2 is attached to the No. 2 guide plate 3T during wet handling and the following No. 2 is not guided to the handling chamber 4, this No. 2 is guided to the No. 2 flow plate 39. The liquid is then guided to the sorting chamber 4, and furthermore, is guided to the sorting starting end of the sorting chamber 4 by the tilting effect of the second flow plate 39, so that the sorting efficiency is greatly improved compared to the conventional method. Furthermore, in the case where the separation plate 41 is provided as in the embodiment,
By providing the No. 2 sink plate 39, no No. 2 lumps are formed on the outer convex portion of the separating plate 41, and sorting can be performed smoothly.
