Description

[Detailed Description of the Invention] The present invention relates to a swing sorting device in a threshing machine.

That is, in a threshing machine configured by extending a swinging sorter equipped with a chaff sheave, grain sheave, stroke rack, etc. from the bottom of the handling chamber to the dust exhaust side,
The oscillating sorting body is divided into right and left sides in the width direction and oscillates in opposite directions, so that vibrations exerted on the machine body are not increased and a well-balanced oscillating motion can be achieved. To provide a structure that enables reliable sorting while dispersing particles well, facilitates disassembly and assembly of a oscillating sorting body, and allows transmission to be carried out easily and favorably. It is something.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a sectional view of a threshing machine mounted on a combine harvester, in which a supply port 7 and a straw discharge port 8 are formed on both sides of the lower part of a handling chamber 6 in which a handling barrel 5 is installed, and a crimp net 9 and a straw removal port 8 are formed below. Equipped with a dust outlet 10,
At the rear of the aircraft, there is a suction port 11 for the suction dust extractor on one side upwards.
A sorting and dust removal chamber 13 is installed in which a discharge port 12 is formed on the rear side.
1, A2 is extended, and below it is the pressure karaki 14,
It is constructed by disposing a No. 1 conveyor 15 and a No. 2 conveyor 16, respectively.

The two oscillating sorters A1 and A2 are formed by dividing a single conventional oscillating sorter into left and right sides from the middle in the width direction so that they are independent from each other. 17, a chaff sheave 1, a grain sheave 2 and a stroke rack 3 are respectively provided in the same manner.

Brackets 18a, 18a, 18b, 18b are vertically installed on the front and rear lower sides of the outer sides of both the swing sorting bodies A1, A2 which are brought close to each other in parallel, and each bracket 18a, 18a, 18b, 1
8b has rollers 19a, 19 made of bearings.
a, 19b, 19b are respectively mounted on shafts, and rollers 19a,
19b are fitted into the guide rails 21a,
21a, 21b, 21b are the rocking sorting bodies A1, A2
Both swinging sorting bodies A1 and A are fixed to each other so as to extend in the swinging direction of the supporting wheels 23, 23, and are mounted on a stay 22 extending from one side.
Both swing sorting bodies A are mounted above both supporting wheels 25, 25, which are mounted so that the inner lower surface of one end side of the two is placed, and which are pivoted on a stay 24 extending from the other side.
1, A2 is installed and configured so that the inner lower surface on the other end side is placed.

Further, a vertical metal 26 supported by the stay 24 is installed below between the rear sides of both the swing sorting bodies A1 and A2.
A vertical support shaft 2 that freely rotates and hangs down.
A longitudinal center portion of an interlocking link 4 made of a horizontally elongated plate is fixed to the lower end of the interlocking link 4.
Longitudinal grooves 28a, 28b formed at both ends of the
are fitted with pins 29a and 29b extending vertically from the center of the width of both the swing sorting bodies A1 and A2, respectively.

A pin 30 protruding from the rear outer side of the right-hand swing sorting body A2 is made to protrude outward from a long hole 31 formed in the side plate 20b, and a transmission pulley 32 is attached to the outer surface of the side plate 20b. A pin 33 is provided protrudingly at the outer eccentric position, and the pin 33 and the pin 30
Both ends of the swing link 34 are fitted and connected to the tip of the swing link 34 so as to be freely rotatable, and a belt 36 is wound around the transmission pulley 32 from the lower pulley 35.

In addition, the oscillating sorting body A2 is arranged so that the upper part of the space between the two oscillating sorting bodies A1 and A2 can be closed.
An elongated plate body 37 is fixed on the inner upper part of the oscillating sorting bodies A1 and A2, and side lips 38 are provided on the inner surfaces of both side plates 20a and 20b so as to close the space between the outer sides of both the swinging sorters A1 and A2.
a and 38b are respectively installed.

Therefore, when the transmission pulley 32 rotates,
The swinging sorting body A2 is moved by swinging back and forth of the swinging link 34.
is swung back and forth, and the oscillating sorting body A1 is swung back and forth via the interlocking link 4 that reciprocates around the support shaft 27, as shown in FIG. Both oscillating sorting bodies A1, A2
move back and forth with the same amplitude in opposite directions as shown by arrows A and B, and therefore the vibrations generated by both oscillating sorting bodies A1 and A2 are attenuated.

In that case, rollers 19a, 19a, 19b,
19b is the guide rail 21a, 21a, 21b,
21b, and are supported by the bearing wheels 23, 23, 25, 25, so that both the swinging sorting bodies A1 and A2 perform a constant swinging motion.

During the work, the two swinging sorting bodies A1 and A2 swing alternately to spread out the objects to be sorted falling from the handling chamber 6, and sort them as in the conventional method.

As described above, the present invention provides a threshing machine in which a swinging sorting body equipped with a chaff sheave, a grain sheave, a stroke rack, etc. extends from the lower part of the handling chamber to the dust exhaust side, and the swinging sorting body is placed in the middle in the width direction. The structure is divided into left and right parts to form two independent swinging sorting bodies, and the two swinging sorting bodies alternately move back and forth with the same amplitude at both ends of the interlocking link, which can rotate as a fulcrum of a longitudinally centered support shaft. Since they are connected in a freely interlocking manner and the swinging sorting body on one side is installed and configured so that it can be driven forward and backward from the side of the aircraft, the vibrations generated by both swinging sorting bodies are canceled out. The vibrations exerted on the machine body are reduced and a balanced rocking motion is performed, and since the forward and backward movements are performed alternately, the material to be sorted can be dispersed, and sorting can be performed well. The structure makes it easy to disassemble and assemble the oscillating sorting body, and the structure also allows transmission to be carried out easily and well.It has a simple structure and has the advantage of being suitable for implementation.
