Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combine harvester used for harvesting a wide range of crops such as rice and wheat, as well as beans and grains, and particularly relates to a combine harvester with an improved sorting section of the threshing 2-selection Wl1 mechanism. It is something.

A conventionally well-known reaping mechanism that is equipped on a traveling vehicle body and pulls up and reaps the crops planted in the field, and a reaping mechanism that inherits the crops harvested by the reaping mechanism and transports and supplies them to the threshing 2 sorting mechanism. In a combine harvester having a transport mechanism, etc., and a threshing 9 sorting mechanism for threshing 3 sorting the crops supplied by the conveying mechanism, the sorting section of the threshing 1 sorting mechanism usually has a swinging sorting shelf, For this reason, the drive mechanism becomes complicated, and the entire aircraft is affected by vibrations caused by rocking, causing various parts to become loose or damaged, which not only deteriorates performance and durability, but also causes damage to the aircraft. There were other problems such as clogging of other substances and the fatigue of the operator.

Therefore, the present invention provides a threshing 5 sorting mechanism that includes an axial flow threshing type threshing section and a screw auger disposed below the threshing section. By composing the net body with a transfer body that receives and conveys the leaked material, the vibration of the machine body is reduced, the durability of the machine body is increased, and the clogging of the material to be sorted is eliminated.
We provide a combine harvester that can simplify the mechanism, reduce operator fatigue, and solve the problems of the conventional methods.
It is intended to be

The invention will now be described with reference to illustrated embodiments.

In FIGS. 1 and 2, reference numeral 1 denotes a vehicle platform having crawler-type running wheels 2, and a weeding device for weeding crops planted in the field is attached to the front of the vehicle platform 1. 3. A reaping mechanism 6 consisting of a pulling body 4 for pulling up the crops and a cutting blade 5 for reaping the base of the crop is attached to the rear of the reaping mechanism 6. A conveying mechanism 7 for holding and conveying the crops is installed to the threshing 9 sorting mechanism 8 which will be described later after inheriting the crops.
is being pulled.

The IBM grain 1 sorting mechanism 8 has a handling chamber 9 in the upper part (), and a handling cylinder 10 is mounted almost horizontally in the handling chamber 9 with its axis in the running direction of the chassis 1. There is a receiving net 11 at the bottom of the chamber 9.
is provided. On the side of the handling room 9, the conveyor 4f is installed.
A foot chain 12 is provided which takes over the crops conveyed in step 17, supplies the head side thereof to a handling chamber 9, and transfers it in the axial direction of a handling cylinder 10. A sorting chamber 13 is provided below and at the rear of the handling chamber 9, and in this sorting chamber 13, screw augers 14 and 15 are installed directly below the receiving net 11, as shown in FIG. It is long so that it extends to the end of the line.

A sorting section receiving net 16.17 is arranged in the receiving gutter portion below the auger 14.15, and the terminal end of this receiving net 16.17 is open. Screw Olga 14゜15
The sorting section receiving net 16, 1 corresponds to approximately the front half of the transport direction.
Below 7 is bell 1, which carries out transport from left to right in Figure 1.
A conveyor 18 is provided, and a first auger 19 is provided below the conveyance end of the conveyor 18, and a second auger 20 is provided below the rear half of the sorting section receiving net 16.17. Being beaten. 2 at the conveyance end of the 2nd port A-ga 2o.
A number return thrower 21 is provided and communicated with the rear end of the handling chamber 9. In addition, in the sorting chamber 13, there is a fan 22 located below the conveyor 18, a suction fan 23 located above the terminal end of the screw auger 14.15 at the rear of the handling chamber 9, and an upper dust exhaust port 24. A lower dust exhaust port 25 is provided at the rear of the auger 20, respectively.
, 1 In the combine harvester configured in this way, as the machine moves forward, the culms of the crops planted in the field are divided by the weed cutting body 3 and combed by the raising body 4.
Rake it in and cut it with the cutting blade 5. Then, the harvested grain culm is held by the conveyor mechanism 7 and threshed.

It is transferred to the sorting machine 114g and transferred to the foot chain 12. The foot chain 12 clamps the stock part of the grain culm and moves the grain culm tip side facing into the handling chamber 9, and during this movement, the grain culm part is threshed by the handling cylinder 10. Most of the threshed grain in the handling chamber 9 leaks through the receiving net 11 and falls onto the front half of the screw auger 16, 17, and the chaff remaining in the handling chamber 9 falls at the end of the receiving net 11. Released from the opening, particles with low specific gravity such as grains with spikes fall onto the screw auger 16, 17, and short culms with low specific gravity, dust, etc. are separated by the wind fan 22 and suction fan 23 and are discharged from the upper part. It is discharged outside the machine from the port 24.

Among the materials to be sorted that have leaked through the receiving net 11, the single grains leak through the front half of the sorting receiving net 16 and 17 and fall onto the belt conveyor 18, and sequentially fall from the conveyance end. Then, the grains are sorted by the sorting air of the grain fan 22, and only the fine grains are brought to the first mouth, and are stored in a container or the like by the auger 19. The materials to be sorted that remain without leaking through the front half of the sorting receiving net 16.17 are mainly grains attached to branches, ear cuts, cob grains, etc., and are removed by rotation and transfer of the screw auger 14.15. , the sorting process is performed, and the sorting receiving net 16
．． What leaked from the second half of 17 was brought to the second port,
The grain is returned to the handling room 9 via the auger 20 and No. 2 return thrower 21, where it is threshed again.

In addition, among the materials to be sorted that have fallen from the rear half of the sorting receiving net 16 and 17, stem culms, dust, etc. with light specific gravity are removed by the round fan 22.
The dust is discharged out of the machine from the lower dust exhaust port 25 by the sorting wind.

In the above embodiment, the No. 2 reduction thrower 21 was connected to the handling chamber 9, but this was connected to the screw auger 14.
．． 15 may be communicated with the intermediate position in the longitudinal direction for reprocessing with screw augers 14 and 15.

In addition, as shown in FIGS. 3 and 4, the screw auger 14.15 has a diffuser 26 placed between the pitches of the screw teeth, and a diffuser rod 27 is installed between the pitches of the screw teeth. In this case, the sorting network 16.17
This prevents clogging and prevents the spiral movement of the material to be sorted.
This results in better sorting and processing performance.

Incidentally, the installation location, number and combination of diffusion members such as the diffuser and the diffusion section may of course be changed as appropriate depending on the content of the material to be sorted leaking from the threshing room, the type of crops, etc. It is something. Further, the number of screw augers is not limited to two as in the embodiment described above, but may be one or more than two. Rani, sorting network 16.1
7, as shown in FIG. 5, the size of the mesh in the portion corresponding to the second auger 20 in the rear half is made 16a (17a) thicker than the mesh size in the front half. Accordingly, when grains with attached branches and stalks, cut grains, etc. occur frequently in the handling chamber 9, leakage to the auger 20 at the second opening is improved, and processing is efficiently performed without causing clogging.

In addition, the mesh size of the receiving net 11 is the same as that of the screening receiving net 16 and 17.
The size of the mesh is slightly larger than that of the mesh.

In another embodiment of the present invention shown in FIG. 6, unlike the combine harvester shown in FIG. The supply type C1 reaping mechanism 6 is equipped with a reel 4a, a scraping auger 28, etc., and threshes the entire amount of grain culms harvested by the conveying mechanism 78.

The feed chain is supplied to the sorting mechanism 8, and the foot chain is omitted. The threshing 1 sorting mechanism 8 is provided with spiral saw teeth 29 and radial saw teeth 30 on the circumferential surface in the handling chamber 9a, and a handling barrel 10a is installed across the length of the threshing 9 sorting mechanism 8. ,
Naturally, the receiving net 11a is also made good, and the rear end of the receiving net 11a, that is, the lower rear end of the handling chamber 9a is opened to form a discharge culm opening 31. In addition, in the sorting chamber 13, the rear end of the screw auger 14.15 is opened to form a dust exhaust port 25a, and a dust exhaust port 251) is also provided at the rear of the second auger 20.
The embodiment is the same as that of the embodiment shown in FIG. 1, except that the speed measuring thrower 21 is communicated with an intermediate position in the longitudinal direction of the handling chamber 9a. Note that the handling cylinder 10a has spiral saw teeth 29 and radial saw teeth 30.
For example, it is not limited to those with a conventionally known handling tooth that has a rearward feeding function.

In this embodiment, the J5 is particularly suitable when the entire amount of harvested culms of wheat, beans, millet, etc. is threshed in the threshing 1 sorting mechanism 8. The grain is released from the culm 31, and the long handling chamber 9a improves the threshing performance and allows the sorting work to be performed well.

As explained above, according to the combine harvester of the present invention, the threshing 1 sorting mechanism includes an axial flow threshing type threshing section, a screw auger disposed below the threshing section, and a receiving gutter of the screw auger. A mesh body and a conveying body for receiving and conveying the material that leaked through the mesh body were installed, so that grains such as rice and wheat are not collected, but beans, miscellaneous grains, etc. It is also possible to thresh the entire amount of grain, and because it does not have a oscillating sorting device like conventional combine harvesters, the mechanism is simplified and the vibration of the machine body is reduced, extending the life of the machine. , the fatigue of the operator is reduced, and it is possible to process rough objects to be sorted without clogging.
