(Effect of Example) Next, we will discuss the effect.

(In the case of rice barley) Hold the handle 33 and pull it toward you, and insert the protrusion 35 into the engagement hole 3.
6, move the inside of the elongated hole downward, and move the rear roller 4 at the rear end of the endless rotary transport sorting body to the position shown by the solid line in Figure 2. When the handle is released, the protrusion 35 moves downward. The endless rotary transport sorting body 25 is engaged with and fixed in the matching hole 36, and the rice and wheat are transferred to the handling chamber 9.
It will be ready to be sent inside. Further, as the rear roller 29 moves downward, the auxiliary receiving net, which is fixed to the rotating shaft g via the mounting bracket 39, overlaps the front end of the handling net 11, as shown in FIG. Further, an insertion frame 47 is inserted into the shelf 44 of the transport elevator 18 so that the non-perforated plate 50 side is the upper surface.

In this state, when the machine 1 is moved forward, the grass is divided by the weed cutting body 6, the rice husk culm is raked by the raking reel 3, the roots of the husk are harvested by the cutting blade 5, and the cut culm is sent to the auger. 4, and transported toward the transport sorting room 24 by the transport heald 20 of the transport nitrator 18.

At this time, the insertion frame 47 is inserted into the shelf 44 of the conveyance element 18 with the bait hole plate 50 side as the fourth side.
Even small grains of rice and wheat can be processed without filtration.

It is transported by performing the function of a normal transporter.

In the conveying and sorting chamber 24, there is an endless rotary conveying and sorting body filter.
Since the grains are set in the state shown by the solid line in the figure, the grains are transported by an endless rotary transport sorter filter and supplied into the handling chamber 9, and are threshed by the rotating handling cylinder 10. The threshed grains are wind sorted. After falling into the chamber 12 and being sorted, the first item is taken out by the first conveyor 14, and the second item is taken out by the second conveyor 15.

(For soybeans) Hold the handle 33 and pull it toward you, and insert the protrusion into the engagement hole 36.
When the handle 33 is released, the rear roller 29 at the rear end of the endless rotary conveying and sorting body 25 is moved from the position indicated by the 21st solid line to the position indicated by the phantom line, and the handle 33 is released. The protrusion 35 is engaged with and fixed in a suitable upper engagement hole 36, and the endless rotary conveying and sorting body 2 is in a state where it is not possible to send large < 1 into the handling chamber 9 f! ! Tilt the furnace to l.

Also, due to the movement of the rear roller 29, the auxiliary bone 1 fixed through the mounting bracket 32:
138 is a drawer T4 pulled out from the front end of the handling net 11 as shown in FIG.
Further, an insertion frame 47 is inserted into the shelf 44 of the transport elevator 18 so that the non-perforated plate 49 side faces upward.

In this state, when the machine 1 is moved forward, the grass is divided by the weed cutting body 6, the soybean husk culm is raked by the raking reel 3, the root of the soybean husk is harvested by the cutting blade 5, and the cut culm is transferred to the auger 4. The materials are collected by the conveyance belt 20 of the conveyance elevator 18 and conveyed toward the conveyance sorting room 24.

0 At this time, since the insertion frame 47 is inserted into #144 of the transport elevator 18 with the non-perforated plate 49 side facing upward, soybeans will not leak, but there is a hole 48 through which dust can be taken out, so dust can be removed. While being removed, it is transported into the transport sorting chamber 24 by the transport belt 20.

Therefore, since the endless rotary conveyance sorting body 2 in the vj separate separation chamber 24 is in a steep slope state as indicated by the above-mentioned phantom line in FIG. Instead, it rolls onto the front end of the endlessly rotating transport sorting body 25 and falls into the supply path 77. Since the supply path ρ is lower on the wind selection chamber η side, it flows into the wind selection chamber 12 and is sorted. Even if the temperature is steep, the soybeans rise, are supplied into the handling chamber 9, are threshed by the rotating handling drum 10, and the threshed soybeans fall into the wind-selection chamber 12, where they join with the shattered soybean grains and pass through the wind. The selected items are taken out by the first conveyor 14 and the second items are taken out by the second conveyor 15.

Meanwhile, the rear roller 29 moves to the upward movement position and moves the auxiliary net feathers upward to feed the supply path ρ, as shown in FIG.
, the threshed grains in the handling chamber 9 are not allowed to flow into the supply path ρ.

In this way, most of the shredded soybean grains are directly air-selected in the wind-selecting chamber 12 without passing through the handling chamber 9, so that long grains with less damage, such as 0 large grains, can be obtained.

In addition, if the voice end rotation conveyance sorting body filter is moved upward and the compensation receiving net feather is moved upward, the handling area will be expanded.
The working time can be lengthened, and if the endless rotary transport sorting body is moved down and the auxiliary catch net feathers are moved down, the handling area is reduced, so the working time is shortened, but the length of the working time is , which affects grain damage, is determined arbitrarily by looking at the condition of the grain being threshed.

The document describes a feeder for a combine harvester, which is used to prevent clogging at the entrance of the handling chamber. However, a combine harvester is used for harvesting rice and wheat, and for harvesting soybeans, and when a combine harvester is designed to be used for both purposes, the rotary feeder does not function effectively. In other words, when harvesting rice and wheat, the structure should be such that the culms are sent into the handling chamber along with the grain.
When harvesting soybeans, the structure should be such that the shredded soybeans are not sent into the handling room, and only the husks are sent into the handling room. If shucked soybeans are sent into a handling room, the large outer skin will be damaged and the product value will be drastically reduced.

However, the present invention includes a traveling device 2 provided below the machine body 1, a reaping section 7 provided in the front of the machine body 1, a threshing section 8 provided above the machine body 1, and a mowing section 7 provided in the reaping section 7.
