Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a handling barrel of a threshing machine for threshing grain culms.

(b) Prior art A threshing machine in which a window is bored in the circumferential surface of a handling barrel and a tooth receiving plate having handling teeth is attached to this window is already known from Japanese Utility Model Application No. 52-38053. ing.

(c) Problems to be solved by the invention Since the known threshing machine described above is simply replaced with a tooth receiving plate having a different number of implanted linear handling teeth, there is a possibility that the grains will be stuck due to the difference in the variety of the grain to be threshed. It was not possible to deal with the removal of grains, or the threshing of grain culms with significantly different shedding properties, such as rice, wheat, and millet, and in order to cope with these problems, the handling barrel had to be replaced.

(d) Means for solving the problem The present invention provides tooth receiving plate mounting portions at multiple locations from at least the middle to the end of the handling cylinder, which has a dust inlet leading to the processing chamber on one side of the end. a tooth receiving plate having a plurality of linear handling teeth fixed at coarse intervals to the tooth receiving plate mounting portion; The plate-shaped handling teeth are screwed in a replaceable manner to a tooth receiving plate which is fixed more closely than the linear handling teeth, and at the end of the handling cylinder, the teeth are fixed to the handling cylinder at intervals in the circumferential direction. The above-mentioned problem was solved by installing a tooth receiving plate on which the plate-shaped handling teeth were attached between the linear handling teeth.

(e) Operation The base of the plant is clamped and transported by the feed chain and the clamping rail, and the ear is inserted into the threshing chamber through the supply port. The threshing teeth on the peripheral surface of the threshing drum and the plate-shaped threshing teeth thresh the grains and remove the prickly grains.

At that time, if you install many tooth receiving plates with plate-shaped handling teeth fixed to the tooth receiving plate mounting part at the rear of the middle,
It is possible to improve the collection efficiency of grain grains, and by installing a large number of tooth receiving plates with sparsely spaced handling teeth from the middle to the end, grain culms or millet with good shedding properties can be collected. It is possible to suppress the amount of ear breakage and straw waste generated during threshing.

In addition, at the end of the handling chamber, plate-shaped handling teeth arranged at intervals in the circumferential direction on the peripheral surface of the handling cylinder perform combing and shedding, and linear handling teeth perform powerful shedding while the side feed is performed. Throw it into the dust outlet.

(F) Example An example of the present invention will be explained with reference to the drawings.
This threshing machine is equipped with a combine harvester, and the handling barrel 1 is mounted on a shaft in the handling chamber 2 with the front part lowered, and as shown in Figures 1 and 2, the dust is sorted from the left rear of the handling chamber 2. A processing section 4 is provided which extends to the terminal end of the chamber 3 and has a front section lower than the rear section and the processing chamber 2, and the processing section 4 is composed of a transfer chamber 4a at the front section and a processing chamber 4b at the rear section, and has a transfer spiral structure. 5 and the processing cylinder 6 are integrated and housed in the processing chamber 4b, and the front end of the processing shaft 7 is supported by the inlet plate 8, and the rear end is supported by the rear wall 9a of the processing chamber 4b via bearings. The transfer chamber 4a and the handling chamber 2 are communicated through a dust inlet 10.

Furthermore, a feed chain 12 and a pinching rail 13 are installed along the handling opening 11 on the left side in the direction of movement, and a swinging sorting body 15 is installed from below the receiving net 14 to the dust sorting chamber 3. A corrugated transfer plate 1 that extends over the entire width and faces the lower surface of the receiving net 14 when viewed from the side.
6, a downwardly inclined flow plate 17a facing the lower surface of the transfer chamber 4a, and a wave-shaped transfer plate 17 facing the uppermost receiving gutter 18.
b, a sorting net 19, and a stroke rack 21 facing above the second receiving gutter 20, and below the sorting net 19 and the stroke rack 21 are wind direction plates 2, respectively.
2, 22, a blower windmill 23 installed at the lower part of the wave-shaped transfer plate 16, and a suction unit installed at the upper part of the rear side of the waste sorting chamber 3 and facing the rear end of the processing chamber 4b. The windmill 24 constitutes a sorting air passage, and the sorting air from a cross-flow fan 25 provided at the front of the second receiving gutter 20 blows through the stroke rack 21 and is blown out to the dust exhaust port 26.

Then, a plurality of cutout windows 27 constituting the tooth receiving plate mounting portion are formed from a slightly forward portion of the middle portion of the handling barrel 1 to the terminal end so that the number of cutout windows 27 is increased toward the rear as shown in FIG. 3. Its size is such that an inserted hand can reach the adjacent cutout window 27, and a plurality of holes 28 are provided around the cutout window 27.

Further, on the outer surface of the notch window 27, there is provided a tooth receiving plate 30, which has a plurality of plate-shaped handling teeth 29, fixed in parallel in the axial direction of the handling cylinder 1, and on the peripheral surface of the handling cylinder. The tooth receiving plate 34 is formed by arranging and implanting a plurality of linear handling teeth 33 at closer intervals than the directly implanted handling teeth 32 and parallel to the axis of the handling cylinder. Then screw it in with bolts 35a and nuts 35b.

That is, if the quality of the grain to be threshed and other factors improve the shedding performance and reduce the generation of straw waste, the handling teeth 33 are sparsely spaced between the rows of densely planted handling teeth 32a in the middle and end portions. Tooth receiving plate 34 with implanted...
If you attach more than the tooth receiving plate 34 with handling teeth and focus on collecting the prickles, use the plate-shaped handling teeth 29...
A large number of tooth receiving plates 30 with attached teeth are installed.

Furthermore, if the straw is to be discharged quickly, a toothed plate 30 is installed at the end of the handling barrel 1, and if the grain removal is to be moved to the dust inlet 10 at the rear of the handling chamber 2, a toothed plate is installed in the middle. 1~ having a lead angle on the receiving plate 30
Three plate-shaped handling teeth 29 are fixed at sparse intervals.

Furthermore, a brush 36 is installed on the outer periphery of the terminal end of the handling cylinder 1 to prevent grains from scattering from the discharge culm opening 37.

In the above-mentioned threshing machine, the stock base of the grain culm is held and conveyed between the feed chain 12 and the pinch rail 13,
When the ear side is inserted into the handling chamber 2 from the supply port, the handling cylinder 1
The grains are removed by the process.

At this time, the narrowly spaced plate-shaped handling teeth 29 fixed to the tooth receiving plate 30 remove the stuck grains as if combing them out, so a large amount of grain culm is supplied and threshed. When threshing grains, or when threshing grains that are likely to generate prickly grains, the prickly grains can be efficiently collected.

In addition, when threshing grain culms and millet grains that are easy to thresh,
If a large number of tooth receiving plates 34 are installed, the occurrence of ear breakage and straw waste will be reduced.

During the threshing of grain culms in this way and generated in the handling room 2, single grains and small straw waste are removed from the receiving net 14 by the corrugated transfer plate 1 of the oscillating sorter 15.
The grains fall into the first receiving gutter 18 from the sorting net 19, and the grains remaining on the sorting net 19 move to the stroke rack 21, where they are transferred and sorted. The objects fall into the second receiving trough 20 and are transferred to the flow plate 17 by the lifting spiral in the second lifting tube at the end of the transfer.
The straw waste is reduced to a, and the straw waste is discharged from the dust outlet 26 to the outside of the machine.

In addition, when the broken ears and large straw waste generated in the handling chamber 2 are moved to the end of the handling chamber 2, they are powerfully disposed of by the handling teeth 32a fixed to the handling barrel 1 and facing the dust inlet 10. When it reaches the part to be treated, the dust is thrown toward it, and the plate-shaped handling teeth 29 located between the handling teeth 32a that are spaced apart in the circumferential direction are combed and processed. The grains enter the transfer chamber 4a of the processing section 4 and are sent to the processing chamber 4b by the transfer spiral 5, and are processed by the processing cylinder 6. Single grains and small straw waste are transferred from the processing cylinder receiving net 6a. Straw waste that falls into the oscillating sorter 15, joins the material to be sorted from the receiving net 14, is sorted, and does not leak out is thrown from the discharge port 47 toward the suction windmill 24. The second straw falls into the straw rack 21, and the straw waste is passed through the suction windmill 24.
and is discharged outside the machine from the dust exhaust port 26.

(G) Effect of the invention Since the invention is configured as described above, the tooth receiving plate 30 or the handling tooth 33 to which the plate-shaped handling tooth 29 is fixed can be used depending on the type of grain culm to be threshed, threshing conditions, or other factors.
By selecting the number of implanted tooth receiving plates 34 and their mounting position with respect to the handling cylinder 1, it is possible to improve the collection rate of prickly grains without replacing the handling cylinder, and to reduce the amount of ear cuts and straw waste generated. can also be suppressed very easily.

In addition, since more tooth receiving plate attachment parts are provided on the terminal end side of the handling barrel 1 than on the starting end side, the plate-like handling teeth 29 and the linear Appropriate threshing processing can be performed by variously changing the arrangement ratio of the handling teeth 33.

Furthermore, on the terminal end side of the handling cylinder 1, plate-shaped handling teeth 29 are installed in the gaps in the circumferential direction of the linear handling teeth, so that the final combing process by the plate-shaped handling teeth 29 and the line By alternately performing strong fragmentation and grain removal using the shaped handling teeth 33, the effects of each treatment can be further improved, and the material to be treated can be accurately introduced into the processing chamber from the dust inlet.
