(Example) An example of the present invention will be described with reference to the drawings.
1 is a traveling device consisting of a pair of left and right crawlers, and a threshing device 2 is mounted above the traveling device 1. A threshing chamber 3 is formed at an upper position on the front side of the threshing device 2 in the traveling direction. The left and right sides of the threshing room 3 are surrounded by vertical side walls, and the front and upper part are surrounded by a ceiling wall 4.
surrounded by

The front part of the threshing chamber 3 is opened to form a supply port 5. A handling net 6 is stretched under the threshing room 3. Inside the threshing chamber 3, a front handling drum 9 and a rear handling drum 10 are pivoted by a front horizontal shaft 7 and a rear horizontal shaft 8 in the left-right direction. The front handling cylinder 9 is formed to have a larger diameter than the rear handling cylinder 10. The rear part of the threshing chamber 3 is opened and becomes a discharge port 11.

At the rear of the discharge port 11, an upper sorting frame 12 and a lower sorting frame 13 for sorting the materials discharged from the discharge port 11 are installed in two upper and lower stages. The upper sorting frame 12 in the upper stage has its front end supported on a fixed part by a shaft 14, and its rear end supported by a support rod 15 that swings alternately.
It is supported by one of the support rods 15 of 16. The front end of the lower sorting frame 13 in the lower stage is supported by a shaft 17, and the rear end is supported by a support rod 16. The lower sides of the support rods 15 and 16 are respectively pivotally attached to the upper and lower ends of a rotating rod 19 attached to a left-right shaft 18, and the rotating rod 19 is rotated by a half turn as shown by arrow A by an interlocking mechanism.

A swing sorting device 21 consisting of a wave-shaped swing sorting plate 20 is attached below the handling net 6 so as to swing back and forth in the direction of the arrow W. The front end side of the swinging sorting plate 20 is bored with numerous sorting holes 22, and below the sorting holes 22 is a guide path 23 which is open to the field. The rear end of the swinging sorting plate 20 protrudes to the center of the wind selection chamber 24, and an armor device 25 whose inclination angle can be adjusted is attached to the rear end of the swinging sorting plate 20.

The armor device 25 is formed in a front half 26 and a rear half 27, and the front half 26 has an inclined plate 28 whose inclination is nearly vertical, and the rear half 27 is formed to tilt backward.

A blower 29 is attached to the lower part of the swing sorting device 21. 30 is a conveyor.

A reaping device 31 is attached to the front side of the threshing device 2. The reaping device 31 is provided with a weeding device 32 for weeding standing soybeans and the like at its front end. A pair of raking belts 33 and 34 are provided at the rear of the weeding device 32 and rotate substantially horizontally (the rear part is slightly higher and tilted forward). The raking belts 33 and 34 rotate symmetrically to each other, and pinch the roots of soybeans or the like between them and guide them rearward.

Above the scraping belts 33 and 34, there are symmetrical guide plates 3 that become higher toward the outside.
5, 36 are attached. The lower ends of the guide plates 35 and 36 face each other leaving a passage 37 for the roots of soybeans, etc., and a thin rubber-like cushioning material 38 is attached to the passage 37 (FIG. 6). Guidance plate 35,
36, when viewed from the side, is taller as it reaches its rear end. The endless scraping belt 33, 3
4 is preferably made of a sponge-like material. The weeding device 32 separates the soybeans standing in the field according to the purpose, and supplies the weeds to the front end portions of a pair of raking belts 33 and 34 facing each other.
The soybean roots are held by the soybeans 3 and 34 and sent backward, and at this time, the rotary cutting blade 39 cuts the soybean roots.

The cutting blades 39 are provided as a pair on the left and right, and some of the cutting blades 39 overlap each other. Further, the diameter of the cutting blade 39 is arbitrary, but for example, if it is about 200 mm, it rotates at a high speed of about 800 to 1000 revolutions per minute.

When cutting, the culm of the soybean is subjected to a shock, and the leeks, which are easily peeled off, may break off and fall, but due to the structure of the guide plates 35 and 36 described above, all the beans are A thin rubber-like cushioning material 38 in the passage 37 gathers in the center of the guide plates 35 and 36.
It is guided backward by the broom action of the soybean stems and leaves that run backwards at the top of the soybean.

Since the cutting blades 39 are partially overlapped with each other, the cutting blades 39 cut in a pressing manner, so there is less vibration, and when rotating at high speed, the phenomenon of falling beans is reduced.

The weeding device 32, guide plates 35, 36, raking belts 33, 34, and cutting blade 39 are attached to a support frame 40. The rear end of the support frame 40 is pivoted 43 to a frame portion 42 to which an auger 41 is attached. Support frame 4
0 is pivoted 43 on the left and right axis, so
The front end has a structure that moves up and down. The above-mentioned weeding device 32, guide plate 35,
Several sets of 36, raking belts 33, 34, and cutting blades 39 are installed side by side in parallel, and each set is moved up and down.

A projection 44 extending downward at a substantially right angle is provided at the rear end of the support frame 40, and the front end of an operating rod 46 of a cylinder 45 is pivoted to the projection 44.

The upper end of the frame portion 42 is fixed to a left-right shaft 47 provided near the supply port 5, and when the hydraulic cylinder 48 is extended, it moves upward as a whole, and the hydraulic cylinder 48 moves upward. It is configured to move downward as a whole when zoomed out. 49 is a scraping belt.

FIG. 7 shows a plan view of the above-mentioned armor device 25, and the rear half 27 has a steeper inclination than the front half 26, but the inclination of the front half 26 can be adjusted by an operating lever 50. The rear half 27 is formed so that its inclination can be adjusted by an operating lever 51.

FIG. 8 shows an embodiment in which a guide plate 52 is installed obliquely in the guide path 23, and the earth and sand that has fallen through the sorting hole 22 flows down the guide plate 52 and falls into the field.

In addition, FIG. 2 also shows a weeding device 32, a guide plate 35,
36 is shown in the figure, the rear end 53 of the weed splitting device 32 is installed so as to face into the passage 37 between the guide plates 35 and 36.

(effect) Next, I will explain the effect.

Since the present invention has the above-described configuration, when the engine is started and each part is rotated, the traveling device 1 moves forward in the field. In this case, the reaping device 31 of the present invention
can be adjusted up and down by the hydraulic cylinder 48, so that it can be adjusted to a desired height by the hydraulic cylinder 48.

Further, even if the field has heights and is not flat, the present invention can be used with the weeding device 32, the guide plates 35, 3
6. Several sets of raking belts 33, 34 and cutting blades 39 are arranged horizontally and attached to the shaft 43, so each set can be moved up and down, so it can adapt to the field conditions. and move forward.

The roots of soybeans etc. that have been weeded by the weeding device 32 are held by a pair of left and right raking belts 33 and 34, and the stems and leaves are guided backward through a passage 37 and cut at the roots by a cutting blade 39. However, at this time, even if the soybean grains come out because the pods are easy to break out,
Since the passage 37 is surrounded by guide plates 35 and 36 in a hopper shape on both sides, the particles are not scattered to the outside and are transferred to the higher rear side by the leaves and foliage transferred to the rear.

In addition, although the cutting blades 39 cut the roots, the pair of rotating disc-shaped cutting blades 39 on the left and right rotate in a state where they are partially overlapped, so the stems and leaves are held down and cut, so there are fewer particles.

Further, since the rotational speed of the cutting blade 39 is very high, there is little vibration, and this also minimizes the generation of peel particles.

The soybean culms fed by the raking belts 33 and 34 are collected in the center by an auger 41 and raked up by a raking belt 49, and then sent from the supply port 5 to the threshing room 3.
It is thrown inside and threshed.

At this time, a considerable amount of earth and sand is mixed into the grain, but this earth and sand is removed by the oscillating sorting plate 20.
The soil is screened out by the screening hole 22 in the front part of the soil, and only the soil flows on the guide plate 52 and falls down the guideway 23 to reach the field. On the other hand, all the threshed grains containing a large amount of pods and the like discharged rearward from the discharge port 11 are discharged onto the upper sorting frame 12 in the upper stage.
One stage of sorting is carried out at the top, and those that pass through this are subjected to two stages of sorting in the lower sorting frame 13, and those containing small impurities fall onto the armor device 25. On the armor device 25, the slope plate 28 of the front half 26 with a different slope is placed together with the first item that passed through the handling net 6.
and are sorted by the inclined plate 28 of the rear half 27,
It is taken out by the conveyor 30.

(Effects) Conventionally, it is known that a swinging sorting device for swinging and sorting the threshed grains is provided in the lower part of the threshing room, and a sorting section is provided in front of the swinging sorting device.

The known oscillating sorting device has a defect in that even pebbles, sand, etc. are moved to the sorting section by the oscillating sorting device.

However, in the present invention, a swing sorting device 21 is provided in the lower part of the threshing room 3 to shake and sort the threshed grains, and pebbles, sand, etc. pass through the front end of the swing sorter 21. This is a grain reaping and threshing device in which a sorting hole 22 is opened, and a guiding path 23 is formed at the bottom of the sorting hole 22 to guide the sieved pebbles, sand, etc. to the field. This has the effect of preventing pebbles, sand, etc. from getting mixed into the sorting section, and therefore preventing dirt from getting mixed into the product.
