Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing apparatus equipped on a combine developed for harvesting small grains such as soybeans and buckwheat.

[0002]

2. Description of the Related Art The above-mentioned threshing apparatus is disclosed in JP-A-2-200.
As disclosed in Japanese Patent Application Publication No. 115-115, there is a configuration in which a supplied harvested crop is hit and threshed by a threshing rotor and discharged and supplied to the front of a swing sorting case.

[0003]

It has been found that the following problems occur when threshing of "buckwheat" is performed by this threshing apparatus. The buckwheat stalks are long and flexible, and when the stalks are harvested and harvested in the blue of the stalks and blown by threshing, the stalks are supplied with the kernels on the rocking sorting case with little cutting and long tangling. Sorting was performed in a state in which the grains had entered between the combined stems, and some of the grains were discharged while being inserted between the stems, so-called "sari loss" was likely to occur. As a means to reduce this "cutting loss", it is conceivable to introduce a dedicated rotary processing cylinder, as is used in a threshing device in a combine for rice and wheat. Larger size, increased weight, complicated transmission structure, etc. are expected. The present invention has been made in view of such a situation, and promotes separation of grains from stems and stems by untangling the processed material supplied on the swing sorting case by adding a simple structure. In this way, the "trivial loss" was reduced.

[0004]

A feature of the present invention is a combine threshing apparatus configured to blow and thresh the supplied cut crop with a threshing rotor and discharge the cut crop to the front of a swing sorting case. At the front of the swing sorting case, a rake-shaped diffusion member that receives the processed material released by the threshing rotor and guides it to fall onto the swing sorting case is arranged, and receives the diffusion member in the front-rear direction. Is provided with a driving means for reciprocating driving.

[0005]

According to the above construction, when the processed material subjected to the hit grain processing by the threshing rotor is discharged and supplied to the front part of the swing sorting case, it is received by the rake-shaped diffusing member which reciprocates back and forth and is released. Upon action, the grains that fall between the entangled stems are separated. Moreover, since the rake-shaped diffusion member is driven back and forth, even if the release energy of the paddy from the threshing rotor is smaller than that of the fixed one, the impact force due to the kinetic energy of the rake-shaped diffusion member is sufficient. It is diffused and the diffusion effect is high.

[0006]

[Effects of the Invention] Therefore, the thresh-processed material is subjected to rocking sorting after being subjected to the unraveling action by the diffusion member at the beginning of the rocking sorting process, thereby effectively separating and collecting kernels. As a result, "slight loss" could be reduced. Moreover, since the diffusion member for unraveling the processing object is provided in the form of a rake that is reciprocated back and forth with the driving means, there is no space disadvantage that a large space is required as in the case of the processing cylinder to be recovered. Further, since the diffusion member is reciprocated by using the driving means instead of colliding with the fixed diffusion member to release the kinetic energy, a change in the kinetic energy of the diffusion member applied to the processing object is performed. Is increased, the processing of a large amount of processed objects can be performed efficiently and effectively, and the "cutting loss" can be reduced.

FIG. 4 shows a main part of a combine according to the present invention. The combine is configured so that the entire harvested crop is fed and supplied to the threshing device 2 by a feed conveyor 1, and a belt for placing and transporting the crops carried in by the feed conveyor 1 is provided in the threshing device 2. A conveyor 3, a threshing rotor 4 for threshing the conveyed crop from below and threshing, a swing sorting case 5 for receiving the thresh-processed material and swinging backward while performing a swing phase, and a sorting wind. Karamin 6, which feeds backwards,
No. 1 screw 7 for collecting and feeding the first product, No. 2 screw 8 for collecting and feeding the second product, sorting where the No. 2 product is placed while rolling and dropping the grain and sent backward The conveyor 9 is provided with a sorting rotor 10 for laterally transporting the foliage while sorting and separating the second and third products. The first and second products collected and laterally fed are respectively a belt-type bucket conveyor 11. , 12 and stored in the respective tanks 13, 14.

FIG. 1 shows the structure of the front part of the threshing apparatus 2. Above the front end of the swing sorting case 5 is provided a rake-shaped diffusion member 15 that is horizontally supported across the left and right side plates of the threshing device 2 and is swingable back and forth, and the lower end of the diffusion member 15 is swing-sorted. The diffusion member 15 is configured to rush into engagement with the transport surface of the case 5 and to swing back and forth as the swinging and sorting case 5 swings back and forth. That is,
The swing sorting case 5 that swings back and forth constitutes a driving unit that receives the diffusion member 15 and drives it back and forth in the front and rear direction.

The diffusion member 15 is located at a position for receiving the threshing product discharged and supplied by the threshing rotor 4 from the direction of the arrow A in FIG. The processing object is firstly the diffusion member 1 moving back and forth.
After being diffused by 5, it is transferred on the sorting sheave 16.

[0010] A diffusion drum 18 provided with a retractable finger 17 is mounted on the left and right side plates of the threshing apparatus 2 at a position above the middle of the swing sorting case 5 in the front and rear direction. The diffusion drum 18 is rotatably driven so that the processed material on the swing sorting case 5 is lifted and diffused forward in the lower working area, whereby the entanglement of the stem is released and the stalk is inserted into the diffusion drum 18. Kernels are separated.

FIG. 3 shows a transmission structure for driving each rotary operating portion in the threshing device. The engine power input to the karyo 6 is transmitted to the threshing rotor 4 through the first belt transmission mechanism 19 in a deceleration manner. After that, it is transmitted to the diffusion drum 18 through the second belt transmission mechanism 20 at a reduced speed.
The power is transmitted to the first screw 7, the second screw 8, and the sorting rotor 10 via the belt transmission mechanism 21. The bucket conveyors 11 and 12 corresponding to the first screw 7 and the second screw 8, respectively, are linked and connected via gear transmission mechanisms 22 and 23. A rotation sensor 24 is provided at the upper end of the bucket conveyor 12 for lifting the second product, and an alarm is issued when it is detected that the rotation speed of the conveyor 12 has fallen below a set value. I have. That is, since the bucket conveyor 12 is at the lowermost position of the transmission yarn, if the rotation of the operating portion on the transmission upper side is reduced due to overload, this is detected by the rotation sensor 24.
