Description

[Detailed description of the invention] (Field of industrial application) The present invention is a threshing machine with a structure in which the dust discharged from the dust exhaust port of the handling chamber onto the swinging sorter is reprocessed by a processing cylinder. Regarding equipment.

(Prior technology) A swinging sorting body is arranged from a sorting chamber at the bottom of the handling room to a sorting dust removal chamber at the rear of the handling room, and the dust is discharged from the handling room dust exhaust port onto the swinging sorting body. In a threshing device configured to separate and sort materials by the oscillating transfer action of a oscillating sorter, there are cases where the threshed grains are supplied with wet material in the handling chamber, or when the threshed grains are oversupplied. In this case, the dust discharged from the handling room becomes a thick layer of cushion-like lumps and is discharged onto the oscillating sorter, and the oscillating motion of the oscillating sorter alone cannot loosen it enough and separate it. Since the dust flows over the oscillating sorter and is discharged outside the machine from the dust exhaust section without sufficient dust, a problem arises in which grains mixed in the dust are carried out of the machine and are lost.

In addition, since lump-shaped dust particles are placed on the oscillating sorter, the oscillating action of the oscillating sorter is naturally reduced, making it easy for clogging to occur. This also causes problems such as a decrease in the sorting performance since the passage of the sorting air becomes difficult.

Therefore, in conventional similar threshing machines, a forced rotating spiral is installed near the dust exhaust port in the handling chamber at the top of the oscillating sorter, and the thick layer of dust is dispersed by the rotation of the spiraler. Some devices are designed to solve the above-mentioned problems caused by the solidified dust flowing over the oscillating sorter.

However, although this conventional method can assist in the dispersion of waste particles, it merely loosens the waste particles through the transporting action of the spiraler, but cannot separate the twig-stemmed grains mixed in with the waste particles. It has not yet been possible to successfully reduce the burden on the oscillating sorter, etc., and
Since the spiral is installed in the threshing machine frame separately from the oscillating sorting body, depending on the operating position of the oscillating sorting body, there may be a gap between it and the spiraler, causing uneven diffusion and preventing good diffusion. There is a drawback that it cannot be planned.

(Purpose of the invention) The present invention was implemented based on the above-mentioned actual situation with the aim of providing a device that solves all the problems that could not be solved with conventional devices.

(Structure of the invention) In the present invention, the processing cylinder whose rotational axis is perpendicular to the processing cylinder is disposed in the handling chamber dust exhaust port above the chaff sheave of the swinging sorter, and the width of the processing cylinder is set as above. The width is approximately the same as the width of the oscillating sorting body, and the processing cylinder is rotated while swinging together with the oscillating sorting body.

(Embodiment) A preferred embodiment of the present invention is shown in the accompanying drawings, and this embodiment will be described below with reference to the drawings.

FIG. 1 is a schematic cross-sectional front view of the main parts of a threshing device according to the present invention, and FIG. 2 is a schematic cross-sectional rear view thereof.

Reference numeral 1 in the figure is a handling chamber, inside which a handling cylinder 3 is supported by a handling cylinder shaft 2 supported between an inlet side plate and an outlet side plate.
is installed on a shaft rack, and a crimp net 4 is stretched along the outer periphery of substantially the lower half of the handling cylinder.

A supply port 5 is provided on the entrance side plate of the handling room, and a discharge culm port 6 and a dust exhaust port 7 are provided on the exit side plate, and the supply port 5 and the discharge culm port 6 are provided on the side wall of the machine casing. A handling port connecting the two is opened, and a feed chain mechanism (not shown) is installed outside the handling port.

From the lower part of the handling room 1 to the rear part on the dust exhaust port side of the handling room, a sorting room 8 and a sorting dust extraction room 9 are installed in communication with each other. Pressure fan 1 in the order of
No. 0 and No. 1 conveyors 11 and No. 2 conveyors 12 are installed.

In addition, a suction dust extractor 13 is installed in the upper part of the sorting dust removal chamber 9.
is installed, and a No. 4 gutter 14 extending obliquely forward and downward is provided in the part of the machine casing where the suction dust exhauster is installed, thereby forming a reduction port 15 at the rear of the treatment room.

In the lower part of the handling chamber 1 and above the air pressure fan 10 and the like, a long oscillating sorting body A is installed along the axial direction of the handling cylinder axis.

The swinging sorter A has a portion corresponding to the lower part of the handling room crimp net 4 as a grain feeding plate portion 16, and an upper portion of the portion extending rearward from a portion corresponding to the handling room dust exhaust port 7 as a chaff sheave 17. At the same time, a grain sieve 18 is disposed below the chaff sieve 17, and a sieve line 19 is further extended from the tip of the chaff sieve.

A portion of the chaff sheave 17 in the oscillating sorter A near the dust exhaust port 7 is formed into a leakage net 17a that is concavely curved downward.

The front side portion of the swing sorting body A is supported by the machine casing by a holding arm 20, and is interlocked and connected by a swing drive arm 21 so as to be able to perform a predetermined swing movement.

In addition, the rear side is attached to a fulcrum shaft 2 provided in the machine casing.
It is supported by hanging arms 23 and 23 that swing at the centers of 2 and 22, and the entire swinging sorting body A is configured to perform a predetermined swinging motion by the operation of the swinging drive arm 21.

Hanging arms 23, 2 are attached to the fulcrum shafts 22, 22.
3, other swingable support arms 24, 24 are respectively attached, and they rotatably support the rotating shaft 26 of the processing cylinder 25, and interlock between the rotating shaft 26 and the fulcrum shaft 22. The processing cylinder 25 is configured to be forcibly rotated by the operation of a transmission mechanism 27 that connects and a transmission mechanism 28 that interlocks and connects the fulcrum shaft 22 and the No. 1 conveyor shaft 11a.

As shown in FIG. 2, the processing cylinder 25 is arranged to have approximately the same width as the oscillating sorting body A, and its axis of rotation is perpendicular to the axis of the processing cylinder. When viewed from the front (Fig. 1), the tips of the handling teeth rotate close to the chaf sheave leakage net 17a, the intake port opens to the dust exhaust port 7, and the discharge port suctions and removes dust on the chaf sheave. The handling teeth in the processing cylinder 25, which are opened toward the machine 13, are
They are arranged in such a way that the processing material transfer action occurs in the direction opposite to the direction of rotation of the handling cylinder 3.

Note that the other reference numeral 29 in the figure indicates a second grain reduction thrower, and 30 indicates a first grain frying conveyor.

Next, the operation of the above-mentioned component device will be explained.

The device starts operating, and the handling cylinder 3, the oscillating sorting body A,
When the pressure fan 10, the No. 2 conveyor 12, the suction dust remover 13, etc. perform their respective predetermined operations, the power is also transmitted to the No. 1 conveyor 11 to operate it, and the transmission mechanism 28 is transmitted from the No. 1 conveyor shaft 11a to the No. 1 conveyor shaft 11a. is transmitted to the fulcrum shaft 22, and further,
From the fulcrum shaft 22 through the transmission mechanism 27 to the rotating shaft 26
is transmitted.

Therefore, the processing cylinder 25 is rotated counterclockwise in FIG.
With this operation, the processing cylinder handles rotates while maintaining a predetermined distance from the leakage net 17a by swinging together with the swinging sorting body A.

When grain culm is supplied from the supply port 5 and threshed in the handling chamber 1 in such an operating state, the dust generated in the handling chamber 1 is transferred from the dust exhaust port 7 to the chaff sheave 17 of the swinging sorter A. is discharged to the top.

Even if the dust discharged from the dust exhaust port 7 is lumped due to factors such as wet material threshing, the dust is received from the reception port side of the processing cylinder 25 and is handled by the rotating handling teeth. It is subjected to an impact load and is loosened, and at the same time, it is spread in the width direction of the chaff sheave 17 by the transfer action produced by the arrangement of the handling teeth.

Then, during the impact application and transfer action by the handling teeth, the twig-stemmed grains mixed with the waste are separated, and together with the grains separated from the waste, some of them are dropped from the leakage net 17a to the grain sieve 18, Grain feeding board part 16
The refined grains are collected on the No. 1 conveyor 11 together with the grains from the grains after being subjected to the sorting action by the grain sieve section.

Dust and particles that do not leak through the leakage net 17a are removed from the discharge port of the processing cylinder through the chaff sheave 1 at the rear.
However, at this time, the twig-spiked grains have been eliminated as described above, and some of the grains have already fallen from the leakage net 17a, so the number of mixed grains is reduced. Moreover, since the entire waste is broken up and spread thinly on the chaff sieve, when it is shaken and sorted on the chaff sieve, separation is carried out well with less burden, and the dust is transferred to the suction dust ejector 13. The passing of the flowing sorting air is also performed satisfactorily, and the number of particles mixed in the dust discharged from the suction dust ejector 13 to the outside of the machine is significantly reduced, so that a sorting process with little loss is performed.

(Effects of the invention) As described above, in the present invention, the processing cylinder that is orthogonal to the handling cylinder is arranged on the chaff sheave of the oscillating sorting body so that it has approximately the same width as the oscillating sorting body, and is integrated with the oscillating sorting body. Since it is configured to be forcibly rotated while swinging, the dust discharged from the dust exhaust port onto the chaff sheave is
At the early stage of sorting on the chaff sieve, the sorting action in which rocking, rotational impact, and transport/diffusion work together allows for good loosening and dispersion, as well as the separation of twig-stemmed grains mixed into the waste. Separated grains can be dropped from the leakage screen to reduce the amount of mixed grains, and the subsequent sorting in the chaff sieve can be carried out extremely well, thereby reducing waste loss.

Furthermore, since the processing cylinder is provided with approximately the same width as the swinging sorting body, the entire width of the swinging sorting body can be used for diffusion processing, and the dust can be formed into a thin layer to allow the sorting air to pass through easily. In addition, since the processing cylinder swings together with the swinging sorter, there is no change in the distance between the processing cylinder handling teeth and the chaff sheave, which eliminates uneven diffusion and allows for good loosening, which has the above-mentioned effect. In conjunction with this, the overall sorting performance has been improved.
