Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a threshing machine with an improved second reductant processing mechanism.

Conventional technology Conventionally, in a threshing machine mounted on a combine harvester, etc., second-reduced materials such as scraps and ear cuts are returned to a handling chamber or a swing sorting section below the handling chamber using a thrower, etc. for re-sorting. Many are equipped with a reduction product processing mechanism.

Problems that the invention aims to solveHowever, returning the secondary reduced products of unprocessed materials such as straw waste, ear cuts, and grains with stalks attached to the handling room again puts an extra burden on the future shedding action of the handling room. This may lead to adverse effects such as a decrease in granulation performance and clogging of the handling chamber. In addition, if the material is directly reduced to the rolling sorting section, the processing power of the untreated material will be reduced, especially in wet materials, etc.
In addition to increasing the number of twigs and scattering, there were also problems in terms of rapid and efficient sorting action.

First Step to Solve the Problems Therefore, the present invention provides a method in which the discharge port of the second reductant cylinder is faced on one side of the grain culm transfer direction terminal side of the handling chamber, and the dust feed port is provided on the other side. The above-mentioned problems are solved by connecting the starting ends of the processing cylinders so as to allow the second reduced product to flow into the processing cylinders via the terminal end of the processing chamber.

Action Straw waste and grain weight attached to branches and stalks are forcibly lifted up and transferred to the secondary material reduction cylinder and returned to the terminal end of the grain culm transport direction in the handling room, but the grain culm is shattered. Since most of the action is completed in the front half of the handling chamber, even if a second material is introduced at the end of the handling chamber, the handling chamber will not be overburdened and the original sloughing function of the handling chamber will not be impaired.

In addition, second-class materials are roughly sorted through a handling cylinder with a large processing force, and then quickly sent through the dust port to the processing cylinder and processed again. Improved ease and smooth transfer of objects without clogging.

Embodiment 2 is a handling chamber of a high-grade de-a machine formed between the front plate 2 on the grain culm supply side and the rear side plate 3 on the grain culm discharge side. It is rotatably mounted on an axis with an inclined shape yE with the side lowered. As shown in FIGS. 5 and 6, the front side plate 2 is provided with a grain culm supply port 2a for normal threshing and a supply port 2b for threshing other than grain culms such as soybeans in two upper and lower stages,
The threshing machine is configured as a multi-purpose threshing machine so that it can be used by switching between an automatic feeding method using a foot chain and a manual feeding method depending on the threshing material. 2c and 2d are composed of four supply ports 2a and 2b that can be opened and closed, respectively.
When the body 2d is opened, the lid body 2d serves as a supply guide plate for soybeans, etc. By the way, on the terminal end side of the grain culm transfer direction of the handling drum 4, a portion corresponding to the opening width W of the dust inlet a is configured to have a small diameter, and a large diameter portion 4b of the handling drum is planted in the vine diameter portion 4a. A long handle vii5a having the same diameter as the outer peripheral diameter of the handle W15 is implanted in a comb-teeth shape. 6 is a receiving net stretched over the entire convergence of the handling room 1. 7 is a processing cylinder, and the processing cylinder 7 is rotatably mounted on a shaft from the terminal end side of the handling chamber 1 to the rear end of the body of the threshing machine A. The processing cylinder 7 has a dust inlet a on the starting end side.
The corresponding part is composed of a spiral body 7a, and the outer circumferential surface of the subsequent part has a structure in which a number of solid shafts 7b are fixedly attached to give a striking action and a feeding action to the workpiece, and the tied end part is provided with an outlet 8. 9 is a receiving net for the processing cylinder. Reference numeral 10 denotes a swinging sorter disposed below the receiving net 6.9, and a dust exhaust port 13 is arranged between the terminal part of the chaff sheave 11 at the rear end and the machine wall 12 facing the corrugated plate 11a. is opened, and a cross-flow fan 14 is mounted on a shaft at the bottom j of the dust exhaust port 13 across the sorting conduit. 15 is the main gutter, 16 is the first gutter, 17 is the second gutter, and between the first gutter 16 and the second gutter 17 is a sub-drill 18. Reference numeral 19 denotes a grain lifting cylinder erected on the transfer end side of the first gutter 16;
The fine grains are stored in a hopper or the like not shown. Reference numeral 20 denotes a second product return cylinder, which is installed obliquely in a cross-connected state with the grain lifting cylinder 19, and its upper part is fixed to the rear side plate 3 of the handling chamber l via a mounting plate 21, and the discharge port 22 at the upper end is It faces the terminal end side (opposite side of the processing cylinder 7) of the handling chamber l, and due to this structure, the second material lifted by the second material reduction cylinder 20 passes through the bottom side of the terminal end of the handling chamber. It flows into the processing cylinder 7. Further, the second reduction cylinder 20 also serves as a support member for the rear side plate 3 of the handling chamber. By the way, E number 2 reduction cylinder 20
has a spiral body 20a that is rotatably installed inside. The inner surface of the second reduction cylinder 20 is opened in the middle in the longitudinal direction, and the opening is communicated with the swinging sorting body IO via the leakage net 24 and the guide trough 25. The corresponding helical body 20a has a processing tooth (for example, see FIG. 7) of an appropriate shape to provide a conveying and processing action to the second item.
It is a spiral body. In this embodiment, the second reduction cylinder 20 is constructed of a spiral body, but the second reduction cylinder 20 is not limited to a spiral body, and may be of a thrower type. As shown in FIG. 8, the lower part of the receiving net 6 than the handling cylinder axis p (the non-shredding surface part in the top-handling type defI machine) is opened at the opening 6a.
At the same time, a cross-flow fan 27 may be provided above the thrower 26, and the pressure of the cross-flow fan may force the second reduction product to be returned to the lower surface side of the treatment chamber 1.
8 is a suction fan, 29 is a feed chain, 30 is a straw removal chain, and 31 is a fine particle leakage net.

In the configuration as described above, during the threshing operation, the receiving net 6 of the handling room l
The material to be handled that leaks from the filter falls onto the oscillating sorter 10 and is subjected to the sorting action, and the fine grains leak through the fine grain leakage net 31 to the first gutter 1.
After flowing down to 6, it is transferred to the - side of the aircraft, and fried grain E, 19
The fried grains are stored in a hopper, etc. not shown. On the other hand, secondary materials such as 6 grains with stems other than fine grains (single grains), ear cuts, and straw waste fall into the second gutter 17 and are similarly transferred to the − side of the aircraft.
It is further conveyed in the second reduction cylinder 20. Further, long straw etc. that have not fallen into the second gutter 17 are discharged from the dust outlet 13 to the outside of the machine. Now, the above-mentioned second product is subjected to a certain amount of processing action by the processing tooth while being conveyed by the second reduction cylinder 20, and the second product is processed to a certain extent by the processing gear. The remaining medium grains pass through the leakage mesh body 24 and are returned onto the oscillating sorter 10 to be re-sorted. After passing through the processing teeth, the second material is further lifted up and conveyed, and introduced from the discharge port 22 at one end to the lower surface of the terminal side of the handling chamber l, after which it is not roughly sorted by the comb-shaped handling teeth 5a. The dust is quickly transferred in the direction of rotation of the handling cylinder 4, and is sent to the dust transfer II along with the long straw etc. generated in the handling chamber l.
It is made to flow into the starting end side of the processing cylinder 7 from a.

By the way, most of the sloughing action in the handling chamber is generally completed in the front half of the handling chamber, so even if a second material is introduced at the end of the handling chamber, it will not reduce the original sloughing performance of the handling chamber or put an overload on it. There is no.

The second material that has flowed into the processing cylinder 7 as described above forms a spiral 7a.
The straw waste is quickly and reliably sent to the solid tooth 7b section, and transferred to the rear of the machine while being processed by the NrittjM7a, 7a, . . . After processing, the straw waste basket is passed through the discharge port 8 at the rear end. The dust is discharged outside the machine from the dust exhaust port 13 at the rear of the machine. Further, the grains which have been reduced to 11 grains by the processing cylinder 7 leak through the receiving net 9 and fall into the ripping sorting body 10L, where they are subjected to a re-sorting action.

As mentioned in Section 2 of ``Effects of the Invention'', the present invention has the discharge port of the second grain reduction cylinder facing one side of the grain culm transfer direction terminal side of the handling room, and the dust processing port facing the second grain reduction cylinder on the other side. The starting end of the cylinder is connected for communication, and the second reduced material is flowed into the processing cylinder via the terminal end of the handling chamber. The second material can be coarsely sorted through a handling cylinder with a large processing power before 2019 without impairing the original granulation function of the chamber, and without placing an excessive burden on the handling chamber, thereby reducing fine particles. It is possible to increase the recovery rate, significantly improve processing capacity, and eliminate problems such as clogging of the handling room.
