Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a threshing and sorting device configured to sort the threshed material from a handling chamber while transferring it in the axial direction of the handling barrel.

Conventionally, in the above-mentioned device, the threshed material from the handling chamber is dropped onto a swinging sorting plate through an opening formed at the terminal end of the handling chamber in the grain culm transfer direction, and is sorted while being transferred in the axial direction of the handling cylinder. Although the system is configured to process the material, the material to be processed tends to concentrate in some areas on the sorting board and fall, and the grains mixed into the material to be processed are not sorted and collected and are released to the outside together with straw waste. However, there was a problem that the grain recovery efficiency decreased.

In view of the above-mentioned points, the present invention makes it possible to distribute and supply the threshed material onto the oscillating sorting plate, and also makes it possible to improve the threshing performance by effectively utilizing the structure for this purpose, and also provides a structure for this purpose. In addition to preventing the scattering of processed materials from the processing room to the threshing waste straw transfer route due to processing, the anti-scattering structure can be effectively used to efficiently collect so-called short-finned paddy mixed in the transferred waste straw. The purpose is to do.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

The structure is such that the grain is supplied to the grains for re-threshing.

A receiving net 15 is stretched under each of the chambers 2 and 4, and openings 16 and 17 are formed at the terminal ends of the chambers 2 and 4 in the grain culm transfer direction, and the openings 16 and 17
A receiver 18 is provided to catch the threshed material falling from the openings 16 and 17 from the lower part of the chamber to the rear, and the threshed material is processed to a size smaller than the set size as the threshing processing is performed in both chambers 2 and 4. The treated material is dropped through the receiving net 15 to the starting end side of the swinging sorting plate 5, separated from fine straw waste, dust, etc., and most of it is collected in the first material collection section 9, and then passed through the receiving net 15. It is configured so that the unprocessed material is dropped and supplied onto the receiver 18.

A rotary body 1 is mounted on the receiver 18 so as to be freely driven and rotatable around a horizontal axis Q that is substantially perpendicular to the handling cylinder axis P.
At the same time, a swing sorting plate 5 is provided at the rear of the receiver 18 to collect the processed material released by the rotating body 19.
A collision member 20 for rebounding is provided above, and the lower part of the receiving device 18 is constituted by a receiving net 21, and the receiving net 1 is mixed into the processed material in the two chambers 2 and 4.
5, but falls from the openings 16 and 17 and is separated due to the stirring action of the rotating body 19, and the processed materials with a size smaller than the set amount are passed through the receiving net 21 and transferred to the No. 1 material collection section 9 on the terminal side. The other processed materials are distributed and supplied onto the oscillating sorting plate 5 while being threshed auxiliary by the cooperation of the releasing action of the rotating body 19 and the rebounding of the collision member 20. It is configured as follows.

The openings 16 and 17 are formed from respective positions corresponding to both ends of the rotating body 19 in the longitudinal direction, and extend approximately 1/3 of the total length of the rotating body 19, and
On the other hand, on the rear end side of the receiver 18, guides 22 are arranged in parallel so that the rear side is oriented toward the left and right center. The threshed material is fed obliquely to the collision member 20, and the bouncing of the threshed material is distributed over almost the entire width of the swinging sorting plate 5 in the lateral direction.

The rotating body 1 is located above the rotating body 19.
With respect to the processed materials that were scattered upwards instead of toward the collision member 20 side due to the releasing action of step 9,
A member 23 for preventing them from scattering to the threshing straw transfer route R from the handling room 2 is installed between adjacent pieces at a predetermined interval to prevent the grains from being scattered from the threshing straw transfer route R. They are arranged in parallel in the waste straw transport direction to form a downstream path r for grain collection,
The upper end of the scattering prevention member 23 is positioned in contact with the transfer straw, and as the scattering prevention member 23 acts on the straw, the small grain paddy is collected by flowing down to the receiver 18. .

Note that the present invention can also be applied to a type of threshing and sorting device that does not include the processing chamber 4.

In summary, the present invention provides the above-mentioned threshing and sorting device with a receiver 18 for receiving the threshed material falling from the opening 16 formed on the terminal end side of the grain culm transfer direction of the handling chamber 2, and A rotary body 19 for discharging the threshed material onto the oscillating sorting plate 5 is provided to be driven and rotated around a horizontal axis Q that is substantially perpendicular to the handling barrel axis P, A plurality of members 23 for preventing the threshed products from scattering from the muscle handling room 2 to the threshed waste straw transfer path R...
The feeding of the threshed straw transfer route R is performed in a state where a downstream route r for grain recovery from the threshed straw transfer route R is formed between them, and in a state where the threshed straw is in contact with the upper end part. It is characterized by being arranged in parallel in the direction.

In other words, the threshing products falling and being supplied from the handling chamber 2 are received by the receiver 18, and the processing products are thrown onto the swinging sorting plate 5 by the rotating body 19 and supplied. However, from the handling room 2 to the receiver 18
Even if the material to be treated falls and is supplied in a concentrated manner to a certain part, it can be dispersed as it is released, and with the releasing action of the rotating body 19, the grains with branches in the material to be processed can be dispersed. It is also possible to thresh grains, etc., and it has become possible to improve both sorting and threshing performance.

Moreover, the scattering prevention member 23 is provided, and the rotating body 1
This prevents the processed material thrown out by 9 from scattering into the threshing waste straw transfer path R from the handling room 2, and prevents straw waste from adhering to the transferred waste straw and causing problems such as clogging of cutters in post-processing. Alternatively, it is possible to avoid inconveniences such as grains adhering to the transfer straw and being discharged to the outside. By doing so, it was possible to recover the small grain paddy mixed in the waste straw, and it was possible to improve the grain recovery efficiency.
