Description

[Detailed description of the invention] (Industrial field of application) The present invention relates to a processing barrel of a combine harvester.

(Prior art) In general, in a full-feed combine harvester equipped with a three-way threshing machine, the grain culm, which has been raked by a raking reel and cut by a cutting blade, is transferred from a raking auger to a chain conveyor in a feeder house. The grain is transported to a handling room and threshed using a screw-type handling barrel or rotor. The threshed grains fall from the crimp net onto the oscillating sorting board, where they are sorted by the sorting wind by the winnowing machine, and the grains fall into the first gutter, the second grains fall into the second gutter, and the grains that fell into the first gutter. is carried to the paddy tank via the grain lifting cylinder, and
The material is returned to the front part of the swing sorting board via a No. 2 reducing auger.

In addition, a processing barrel with an open input port for the No. 2 reduction port is provided separately from the rotor, and the processing barrel is exposed to the sorting section through a receiving net, as disclosed in Japanese Utility Model Publication No. 56-43144 and Utility Model Application Publication No. 56-43144. It is known from Publication No. 54-13866.

(Problems to be solved by the invention) In the former type of full-feeding combine harvester equipped with a screw-type axial flow threshing machine, there is a lot of leakage near the rotor inlet, and the stems and grains fall together.
With the current oscillating sorting machine, there is a limit to the separation and sorting of these stalks and spike grains, even if the angle of the chaff sieve can be adjusted, and they are most likely to get mixed into the gutter. Furthermore, none of the latter types has a structure in which the terminal end of the processing cylinder is located in the middle of the chaff sheave of the swinging sorting device. Therefore, even if this is used in a full-feeding combine harvester equipped with a screw-type axial flow threshing machine, there is a limit to the separation and sorting of stems and ear cut grains, which will most likely get mixed into the gutter.

(Means for Solving the Problems) Therefore, the technical problem of the present invention is to provide a processing barrel for a combine harvester that can process branches and stalks, and the present invention aims to solve this technical problem. The technical means is to provide a processing barrel chamber with a No. 2 reduction input port opened separately from the rotor in a full-feeding combine harvester, and the processing barrel chamber faces the sorting section through a crimp net, and the terminal end of the processing barrel The present invention is characterized in that it is arranged so as to be located in the middle of the chaff sheave in the swinging sorting device.

(Example) The embodiments shown in the drawings will be described below.

First, we will explain the whole of a full-feeding combine harvester equipped with a conventional screw-type threshing machine using the proposed device.

In FIG. 1, the crop is raked by a raking reel 1 and cut by a cutting blade 2, and the cut crop is transferred from a raking auger 3 to a chain conveyor 5 of a feeder house 4.
The grain is then transported to a handling room 6 and threshed using a screw-type handling cylinder, that is, a rotor 7.

The threshed grains fall from the crimp net 8 onto the oscillating sorting board 9 and are sorted.

The grains threshed on the swinging sorting board 9 are sorted only for long straw, which is transported to the rear in the direction of dust removal.

In addition, the materials to be sorted by the swing sorting board 9 are sorted by the sorting wind by the chisel 10, and the grains fall into the first gutter 11, the second objects fall into the second gutter 12, and the grains that fall into the first gutter 11 fall into the first gutter 11. is carried to the paddy tank via the grain lifting cylinder, and
The second item that fell into the gutter 12 is the second reduction auger 13
It is designed so that it is returned onto the oscillating sorting board 9.

In the present invention, in the combine harvester as described above, a processing cylinder 14 for processing unprocessed grains is interposed between the crimp net 8 of the handling chamber 6 and the swinging sorting plate 9 in parallel to the rotor axis.

Spiral rotation in the feeding direction toward the dust feeding port (largest port No. 3). Then, the second reduction inlet 20 is opened on one side of the processing barrel chamber 15, and the dust exhaust port 16 is opened at an intermediate position of the chaff sheave 17.

In the figure, 18 is a chaff sheave, 19 is a grain sieve, and 21 is a crimp net in the processing barrel. In the illustrated example, the processing cylinders 14 in the processing cylinder chamber 15 are arranged in two rows.

When the processing cylinder 14 as described above is provided, the No. 2 reduced product is processed in the processing cylinder 14, and the stems and ears are processed.

Moreover, the mesh of the crimp net 8 in the handling chamber 6 is made large so that even if branches and ears fall into the second gutter, they will not be removed from the processing cylinder 1.
Step 4 allows processing of stems and spikes, increasing processing capacity.

In addition, since the end of the processing cylinder 14 ends in the middle of the chaff sheave 17 of the rocking cylinder sorting board 9, the chaff sheaves 17 and 18 can be effectively used to efficiently perform separation and sorting.

Incidentally, the processing cylinder 14 is dedicated to the No. 2 reduced product, and may be provided outside the machine body as shown in FIGS. 3 and 4.

(Effect of the invention) According to this technical means, since the second product is returned from the second gutter to the processing chamber and processed there, it is possible to dispose of branches and ears.

In addition, since there is a processing cylinder, the crimp mesh in the handling chamber can be enlarged, the processing capacity can be increased, and the generation of small grains can be prevented. In addition, since the end of the processing cylinder is located in the middle of the chuck sheave of the swinging sorter, the processing barrel chamber can be placed within the size range of the swinging sorter, and the equipment can be configured compactly. In addition, the stalks and spike grains processed in the processing barrel chamber can be separated and sorted by effectively utilizing the chaff sieve of the rocking barrel sorting device.
