Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a reaping device in a soybean reaping and threshing device.

(Prior Art) The 24th volume of "New Country", which is known in the art, includes:
Reaping of soybeans, etc., in which a threshing device is mounted on a traveling device, and two sets of a weed splitting device, a guide plate, a raking device, a cutting blade, and a grounding means are fixedly attached to the front side of the threshing device. The threshing equipment is described.

Furthermore, Japanese Patent Application Laid-open No. 49-84817 describes a device in which a grain collecting device is mounted on a traveling device, and a set of a weeding device, a guide plate, and a raking device are attached to the front side of the device. .

Further, Japanese Utility Model Application Publication No. 51-92421 describes a reaping device for reaping and threshing equipment for soybeans, etc., which includes a rake belt, an auger, and a cutting blade as a set.

Furthermore, Japanese Utility Model Application No. 54-99832 describes a device in which a raking belt is provided on a traveling device, and a weeding device, a guide plate, a cutting blade, and a grounding means are attached to the front side of the raking belt. There is.

Furthermore, Japanese Patent Application Laid-Open No. 52-43628 discloses a set in which a threshing device is mounted on a traveling device, and a raking belt, etc., a weeding device, a pulling belt, and a cutting blade are provided on the front side of the threshing device. There is described a reaping and threshing device for rice and wheat that is constructed by installing a plurality of sets and moving each set up and down separately using a hydraulic cylinder.

(Problems to be Solved by the Invention) The device described in the 24th volume of "New Country" has a set of weeding device, guide plate, raking device, cutting blade, and grounding means on the front side of the threshing device. Two sets of mowers are installed in a fixed manner, making it possible to mow in two rows, which is efficient. However, since both sets are installed in a fixed manner, each set can move up and down to accommodate the unevenness of the field. This may not be possible, and one group may have a high cut. On the other hand, the other group may also push into a partial convexity on the ground surface. Also, when doing maintenance, you have to lift both cutting parts, which makes the work difficult.

Japanese Unexamined Patent Publication No. 49-84817 and Utility Model Application No. 51-92421
All of the cutting blade devices described in the above publication are inefficient because they have only one set of cutting blade devices.

What is described in Utility Model Application Publication No. 54-99832 is
Although there are two sets of mower blades, since they are fixed, there are problems similar to those pointed out in the 24th volume of "New Country".

What is described in Japanese Patent Application Laid-open No. 52-43628 is
The conveyance section and the reaping section do not move up and down separately, but the conveyance section and the reaping section move up and down together (integrally) by one cylinder. Therefore,
It is not possible to vertically adjust only the reaping section to accommodate the complex unevenness of the field without moving the conveying section up and down. The optimum transporting posture of the transporting section is determined, but as mentioned above, when the transporting section also moves up and down, the optimal transporting posture changes, so while continuing the smooth transporting action, only the reaping section can be moved over the unevenness of the fields. It becomes impossible to adjust the height to correspond to the height. In addition, since the reaping section as a whole moves up and down, adjusting it to accommodate the unevenness of the field may result in high mowing in some areas, and when performing maintenance, it is not necessary to lift not only the reaping section but also the conveying section. It's difficult to work because you don't have to do it.

(Means for Solving the Problem) Therefore, the present invention provides a merging conveyance frame 4 in which a threshing device 2 is mounted on a traveling device 1, and a raking belt 49, an auger 41, etc. are mounted on the front side of the threshing device 2.
2, a left-right shaft 43 is attached to the front end of the merging conveyance frame 42, and a weeding device 32 is attached to the shaft 43.
A plurality of sets of reaping parts are installed, each of which includes the guide plates 35, 36, the raking belts 33, 34, the cutting blade 39, and the grounding means, and the merging conveyance frame part 42 and the reaping part are attached to the threshing device 2. Hydraulic cylinder 4
8 so as to move up and down integrally, and the reaping section is configured to move up and down separately for each set with respect to the merging conveyance frame section 42 by separate hydraulic cylinders 45. It is used as a reaping device in a threshing device.

(Example) An example of the present invention will be described with reference to the drawings.
is a traveling device, and a threshing device 2 is mounted above the traveling device 1.

In the threshing device 2, a threshing chamber 3 is formed at an upper position on the front side of the threshing device 2 in the traveling direction. The threshing room 3 is surrounded by vertical side walls on both left and right sides, and is surrounded by a ceiling wall 4 at the front and upper part. A ceiling wall 4 at the front of the threshing room 3 is opened in the left-right direction to form a supply port 5. A handling net 6 is stretched at the lower part of the threshing room 3.

Inside the threshing chamber 3, handling barrels 9 and 10 are attached by horizontal shafts 7 and 8 extending in the left and right direction. The handling cylinder 9 is located on the front side, and the handling cylinder 10 is located on the rear side. The handling cylinder 9 is formed to have a larger diameter than the handling cylinder 10.

The ceiling wall 4 and the rear end of the handling net 6 are opened in the left-right direction to form a discharge port 11. In the threshing device 2, behind the discharge port 11, sorting frames 12 and 13 for sorting the grains discharged from the discharge port 11 are installed in two upper and lower stages. The front end of the upper sorting frame 12 is connected to the shaft 1.
4, and the rear end is supported by support rods 1 that swing alternately.
It is supported by one of the support rods 15 of 5 and 16. The lower sorting frame 13 has its front end supported by a shaft 17 and its rear end supported by a support rod 16.

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 reciprocated and semi-rotated as shown by arrow A by an interlocking mechanism.

A sorting device 21 consisting of a wave-shaped swinging 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 provided with numerous sorting holes 22.
The lower taxiway 23 faces 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 slope of the inclined plate 28 of the front half 26 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 at its front end for weeding soybeans. A pair of raking belts 33 and 34 are provided at the rear of the weeding device 32 and rotate substantially horizontally (the latter half is slightly higher and tilted forward). The raking belts 33 and 34 rotate symmetrically to each other, and between them, the soybeans are clamped and guided rearward.

At positions above the raking belts 33, 34, symmetrical guide plates 35, 36 are attached which become higher toward the outside and higher toward the rear over the entire length, respectively. The lower ends of the guide plates 35 and 36 face each other leaving a soybean passage 37.
A thin rubber-like cushioning material 38 is attached to the portion.

When viewed from the side, the guide plates 35 and 36 become taller toward the rear end. The endless scraping belts 33 and 34 are 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 is clamped and sent backward, and at this time the root of the soybean is cut off with the cutting blade 39. During cutting, a considerable impact is applied to the soybean grains, and the pods that are in a state of being easy to burst may break off and fall, but due to the structure of the guide plates 35 and 36 described above, , all beans are collected in the center and guided to the rear. Furthermore, when the cutting blade 39 is rotated 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 support frame 40 has its rear end pivoted to a merging conveyance frame 42 to which an auger 41 is attached. Support frame 4
0 is mounted on a shaft 43 in the left and right direction, so
The front end has a structure that moves up and down. On the shaft 43 of the shaft attachment part, the above-mentioned weeding device 32 and guide plate 35,
36, raking belts 33, 34, cutting blades 39, and grounding means are installed in several sets in parallel horizontally, and each set is moved up and down.

A protrusion 44 extending downward (at a right angle) is provided at the rear end of the support frame 40.
An operating piece 46 of a cylinder 45 is pivotally attached to the cylinder 4. The merging conveyance frame 42 has an upper end fixed to a left-right shaft 47 provided near the supply port 5, and moves upward as a whole when the hydraulic cylinder 48 is extended. 48 is configured to move downward as a whole when contracted.
49 is a scraping belt.

FIG. 7 shows a plan view of the above-described armor device 25, in which the inclination of the front half 26 of the inclined plate 28 is adjusted by an operating lever 50, and the inclination of the rear half 27 is adjusted by an operating lever 51. be done.

FIG. 8 shows an embodiment in which a guide plate 52 is provided obliquely within the guide path 23.

Also, in FIG. 2, a weeding device 32 and a guide plate 3 are shown.
5 and 36 are shown in the diagram (the weeding device is formed of a rod-like body), the rear end 5 of the weeding device 32
3 is attached so as to partially overlap the guide plates 35 and 36 and face into the passage 37 between them.

(effect) Next, we will discuss 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 of the present invention:
A merging conveyance frame portion 42 to which a scraping belt 49, an auger 41, etc. are attached is provided, and the merging conveyance frame portion 4
A left-right shaft 43 is attached to the front end of the shaft 43.
, a plurality of sets of reaping parts are installed, each of which includes a weed splitting device 32, guide plates 35, 36, raking belts 33, 34, cutting blade 39, and grounding means. and the threshing device 2
Since the whole is moved up and down by a hydraulic cylinder 48, first, the whole is adjusted up and down by the hydraulic cylinder 48 to determine the reaping height. Each set of parts 42 is moved up and down by a separate hydraulic cylinder 45.

Therefore, even if the field has heights and is not flat, the reaping section can be constructed by combining the weed splitting device 32, the guide plates 35, 36, the raking belts 33, 34, the cutting blade 39, and the grounding means as a set, and carry out the above-mentioned combined conveyance. Since it is separated from the frame part 42 and moved up and down individually for each set, even if the surface of the field is uneven, it can be quickly adapted and harvested.

In addition, since only the reaping section is moved up and down by the hydraulic cylinder 45, and the merging conveyance frame section 42 is not moved up and down, a smooth conveying action can be expected, and only the reaping section can be adapted to the unevenness of the fields while continuing the smooth conveying action. I can do it.

Further, since the reaping sections are separated from the merging conveyance frame section 42 and moved up and down separately for each set, maintenance can be easily done by moving the necessary reaping sections up and down for each set. I can do it accurately.

In addition, since each set moves up and down separately, there is no chance of them hitting a partial convexity, which helps prevent damage.

The soybeans etc. that have been weeded by the weeding device 32 are cut at their roots by the cutting blade 39 while being crimped and held by the left and right pair of raking belts 33 and 34. Since the root is cut by the cutting blade 39 while being cut, the cutting is smooth.

Furthermore, even if soybean grains burst due to the pods being easy to burst, the passage 37 is surrounded by guide plates 35 and 36 from both sides in a hopper shape, so the burst grains will hardly be released to the outside. .

Also, the root is cut with the cutting blade 39, but the cutting blade 39
Since the rotational speed is very high, cutting is performed without much vibration, thereby minimizing the generation of splintered particles.

The soybean culms fed by the raking belts 33 and 34 are collected in the center by an auger 41, raked up by a raking belt 49, and thrown into the threshing chamber 3 through the supply port 5 to be threshed. At this time, a considerable amount of earth and sand is mixed in during grain threshing, but this earth and sand is sieved out by the sorting hole 22 in the front part of the swinging sorting plate 20, and only the earth and sand is left on the guide plate 52. It flows down the taxiway 23 and reaches the field. On the other hand, all the threshed grains containing a large amount of pods etc. discharged backward from the discharge port 11 are discharged onto the upper sorting frame 12, where they are sorted in one stage, and those that pass through this are sorted in the lower stage. One stage of sorting is performed in the frame 13, and those containing small impurities fall onto the armor device 25. On the armor device 25, the first items that have passed through the handling net 6 are sorted by the inclined plate 28 of the front half 26 and the inclined plate 28 of the rear half 27, which have different inclinations, and are taken out by the conveyor 30. .

(Effects) In the present invention, the threshing device 2 is mounted on the traveling device 1, and the merging conveyance frame 42 is provided on the front side of the threshing device 2 to which the raking belt 49, the auger 41, etc. are attached, and the merging conveyance frame 42 is provided on the front side of the threshing device 2. A left-right shaft 43 is attached to the front end of the section 42, and the weeding device 32, guide plates 35, 36, raking belts 33, 34, and cutting blade 3 are attached to the shaft 43.
A plurality of sets of reaping sections each including 9 and grounding means are attached, and the merging conveyance frame section 42 and the reaping section are connected to the threshing device 2 by a hydraulic cylinder 48.
The soybean reaping and threshing apparatus is constructed such that the reaping section is configured to move up and down integrally with respect to the merging conveyance frame section 42, and the reaping section is configured to be moved up and down separately for each set by separate hydraulic cylinders 45 with respect to the merging conveyance frame section 42. Since it is a reaping device in the device, (a) the merging conveyance frame portion 42 and the reaping portion are:
Since the threshing device 2 is provided so as to be moved up and down as a whole by a hydraulic cylinder 48, the combined conveyance frame section 42 and the reaping section can be adjusted up and down to the optimal conveying state and reaping state as a whole by the hydraulic cylinder 48. can do.

(b) Since only the reaping section can be vertically adjusted for each set by separate hydraulic cylinders 45 with respect to the merging conveyance frame section 42, even if the field has partial heights and is not flat, the weeding device can 3
2, guide plates 35, 36, and scraping belts 33, 34
The reaping section, which includes a cutting blade 39 and a grounding means, can be separated from the merging conveyance frame section 42 and moved up and down only as needed.

C. Only the reaping section can be moved up and down using the hydraulic cylinder 45. At this time, since the merging conveyance frame 42 is not moved up and down, the merging conveyance frame 42 can continue to operate in the set best conveyance posture. Therefore, only the reaping section can be adjusted to accommodate the complicated unevenness of the field while continuing the smoothest conveying action.

D. The reaping sections are separated from the merging conveyance frame section 42 and moved up and down separately for each set, so during maintenance, the merging conveyance frame section 42 and unnecessary reaping sections remain, and only the necessary reaping sections are removed. The simplest method is to move only one set up and down, making maintenance work extremely easy.

In addition, since the reaping parts move up and down individually for each set, they do not poke into local convexities on the ground surface, which helps prevent damage.

This effect is achieved.
