Description

Description: FIELD OF THE INVENTION The present invention relates to a thresher having an improved second reduction product treatment mechanism.

2. Description of the Related Art Conventionally, in a thresher mounted on a combine, etc., a second reduction product such as scraps and cuttings is reduced by a thrower or the like into a swinging sorting section in a handling room or a lower side of the handling room for re-sorting. Many are equipped with a reduction product processing mechanism.

Problems to be solved by the invention However, untreated second-reduced products such as straw scraps, cuttings, and branch adhering particles are treated with a thrower that throws from one side of the rear wall of the treatment chamber toward the supply port side. When it is returned to the chamber and processed, the thrown second object moves to the middle of the handling chamber or near the supply port and is processed by the handling cylinder. An additional overload is applied to the starting end side and the subsequent part, which causes an abnormal overload on the handling cylinder and the grains in the second reduced second product are treated by the handling teeth of the handling cylinder. There was a problem that it was excessively processed and damaged. In addition, if it is directly returned to the oscillating sorting section, the processing capacity of untreated materials is reduced, especially in the case of a wet material, and the increase of twigs and the occurrence of third scattering are likely to occur, and it is quick and efficient. There was a problem in terms of proper sorting.

MEANS FOR SOLVING THE PROBLEMS The present invention is directed to the side wall of the handling chamber, in which the discharge port of a second product reducing cylinder in which a spiral body is provided on one side of the terminal side in the grain transfer direction is directed toward the peripheral surface of the handling cylinder. From the other side, the other end is connected via the dust inlet to the start end of the processing chamber with the processing cylinder inside, and the second reduction product is allowed to flow into the processing chamber via the end of the handling chamber. By doing so, the above-mentioned problems were solved.

Action The secondary products such as straw scraps and grains attached to branch shoots are forcibly lifted and transferred by the secondary product reduction cylinder and returned to the terminal side in the grain transfer direction of the handling room, but the grain shedding action is handled. Since most of the treatment is completed in the first half of the chamber, even if a second material is introduced to the end of the chamber, it does not overload the chamber and does not impair the original shedding function of the chamber. In addition, since the second product is roughly selected in advance through a handling cylinder with a large processing capacity, it is quickly fed to the processing cylinder from the dust outlet and processed again, improving the processing capacity and clogging. The object to be processed can be transferred smoothly.

Example 1 is a handling chamber of an upper handling type threshing machine formed between a front side plate 2 on the grain culm supply side and a rear side plate 3 on the grain culm discharge side. It is rotatably mounted in a tilted state with a low height. As shown in FIG. 5 and FIG. 6, the front side plate 2 is provided with a grain culm supply port 2a at the time of normal threshing and a supply port 2b at the time of threshing of soybeans other than the grain stalk in upper and lower stages, depending on the threshing material.

Is provided. Reference numeral 19 denotes a fried food container which is erected on the transfer end side of the first gutter 16. The fried food container 19 allows refined grains to be stored in a hopper or the like (not shown). 20 is a second product reduction cylinder, which is obliquely installed in a cross-connected state with the fried grain cylinder 19,
The upper part thereof is fixed to the rear side plate 3 of the handling chamber 1 via the mounting plate 21, and the discharge port 22 at the upper end is from the one end side of the handling chamber 1 (the opposite side of the processing drum 7) to the end of the handling barrel 4. The second object lifted by the second object reducing cylinder 20 flows into the processing cylinder 7 via the lower surface side of the terminal end of the handling chamber by this structure. Has become. The second reduction cylinder 20 also serves as a support member for the rear side plate 3 of the handling chamber. By the way, the second reducing cylinder 20 is a rotatably mounted spiral body 2
It has 0a. The inner side surface of the second reducing cylinder 20 in the longitudinal direction is opened, and the opening b is communicated with the swing selecting body 10 through the leak net 24 and the guide gutter 25, and the opening b is opened. Corresponding spiral body 20a is a spiral body with processing teeth (e.g., see FIG. 7) having an appropriate shape so as to give a conveying and processing function to the second object. 28 in the figure
Is a suction fan, 29 is a feed chain, 30 is an exhaust straw chain, and 31 is a fine grain leakage net.

With the above-mentioned configuration, the receiving net 6 of the handling room 1 during the threshing work

After flowing down to 6, it is transferred to one side of the machine, and is fried and stored in a hopper or the like (not shown) in the fried cylinder 19. On the other hand, the second ones such as branch adhering grains other than refined grains (single grain), cuttings, straw scraps, etc. are second gutter 1.
After dropping to 7, it is similarly transferred to the one side of the machine body and lifted and conveyed by the second reduction cylinder 20. Further, long straws and the like that have not fallen to the second gutter 17 are discharged from the dust exhaust port 13 to the outside of the machine.
By the way, the second product is subjected to a certain processing action by the processing teeth a while being conveyed by the second reduction cylinder 20, and the processed single particles pass through the leakage net body 24 and are returned to the swing sorting body 10. And re-sorted. After passing through the processing tooth B, the second object is further lifted and conveyed, and is introduced from the upper end discharge port 22 toward the outer peripheral surface of the end portion of the handling cylinder 4 at the end side of the handling chamber 1, and then the comb tooth-shaped handling is performed. While being roughly processed by the teeth 5a, they are rapidly transferred in the rotation direction of the handling cylinder 4, and are made to flow into the starting end side of the processing cylinder 7 from the dust-sending port a together with the long straw or the like generated in the handling chamber 1.
By the way, most of the shedding action in the handling room is completed in the first half of the handling room, so even if a second material is introduced at the end of the handling room, the original shedding performance of the handling room may be reduced or an excessive burden may be imposed. Absent.

The second product flowing into the processing cylinder 7 as described above is the spiral body 7a.
Is quickly and surely sent to the solid teeth 7b portion, and is transferred to the rear of the machine while being treated by the solid teeth 7a, 7a ... It is discharged to the outside of the machine from the dust outlet 13. Further, the grains that have been made into single grains by the processing cylinder 7 leak through the receiving net 9 and fall on the rocking sorting body 10 to undergo a re-sorting action.

EFFECTS OF THE INVENTION As described above, according to the present invention, the discharge port of the second product reducing cylinder in which the spiral body is installed on one side of the terminal end side of the handling chamber in the grain culm transfer direction is directed from the side wall toward the peripheral surface of the handling cylinder. The other end is configured so that the starting end side of the processing chamber, in which the processing cylinder is installed, is connected to the other side through the dust inlet, and the second reduction product flows into the processing chamber via the end side of the handling chamber. Therefore, the second material that has been lifted by the spiral of the second reduction cylinder is introduced from the discharge port toward the peripheral surface of the end portion of the handling cylinder on the one side of the handling chamber, and from that to the start end side of the handling cylinder.
