Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a threshing sorting device.

[Conventional technology]

In a threshing sorting device, if the amount of shell culm supplied to the handling chamber is less than the set maximum amount, the smaller the amount supplied, the less the grains will rub against each other, and the second processing material from the sorting section will have a relatively strong recycler. This increases the amount of untreated substances that are mixed in in an untreated state that requires treatment action. In view of this, conventional methods have been proposed, for example, in Japanese Patent Laid-Open No. 85119/1985, which automatically adjusts the amount to minimize reprocessing defects and grain damage, regardless of changes in the supply amount. There was something.

In other words, when the grain culm supply 1Fk is small, the amount of the No. 2 processed material, which is returned from the sorting section to the handling room and imparts strong reprocessing action, is automatically increased, and when the grain culm supply is large, teeth,
The amount of the No. 2 processed material that is returned to the oscillating sorting device from the No. 2 processed material take-out device in the sorting section and is reprocessed while being washed to avoid grain damage due to the mild re-spinning action accompanying the sorting action. is automatically increased.

To be more specific, by swinging the distribution guide plate based on the information detected by the grain amount detection sensor, the flow of the second processed material to be distributed and supplied to the handling room and the sorting section is adjusted. There is.

[Problem that the invention seeks to solve]

In the conventional case, a grain detection sensor, a distribution guide plate, an actuator for swinging the grain guide plate, an automatic control device, etc. are required, and the structure becomes complicated.

An object of the present invention is to provide a product with a simple structure that allows operations to be carried out with minimal under-processing or damage to grains, regardless of the amount of husks present.

[Means for solving the problem]

The characteristic configuration of the threshing and sorting device according to the present invention is that a vertical screw conveyor is provided for transporting the second processed material from the sorting section, and a rotating body is provided which discharges the processed material from the vertical screw conveyor and supplies it to the sorting section. , it is provided at the terminal end of the vertical screw conveyor so as to be rotatable around the vertical axis, and a net-like body for reprocessing the processed material is provided only in the lower layer of the supply path by the rotary body, and its functions and effects. is as follows.

[Function] The entire amount of the No. 2 processed material from the sorting section is returned to the sorting section through the supply path by the vertical screw conveyor and the rotating body, but when the amount of culm supplied is small, the second processing material is returned to the sorting section. Since the amount of the No. 2 processed material is also reduced and passes through the lower side of the supply channel, most or the entire amount passes through the mesh body due to the transfer force of the rotating body and undergoes a strong reprocessing action. It is granted. When the amount of shell culm supplied is large, the amount of the second processing material from the sorting section also increases and passes through the entire or most part of the supply channel, so some of it may pass through the net-like body. The residue passes through the upper layer of the supply channel without a mesh, and is subjected to a weak re-sweeping action accompanying the sorting in the sorting section.

〔Effect of the invention〕

Due to the effects of the processing material conveying structure, the mesh body, and its arrangement, when the amount of shell culm supplied is small, most or all of the second processing material is strongly reprocessed, and when the amount of shell culm supplied is large, As the amount of only a weak reprocessing effect is automatically adjusted to increase, the process can be carried out with as little threshing failure or grain damage as possible regardless of changes in the amount of husk supplied. This makes it possible to simplify the structure so that special sensors and automatic control mechanisms are not required, which is economically advantageous.

〔Example〕

As shown in Fig. 1, a rotary handling barrel (2) is installed in a handling chamber equipped with a receiving net (1), and the shell culm is inserted with the cone and the tip of the shell culm into the supination of the handling chamber. A tweed chain (3) for holding and conveying the stock head is provided on the side of the machine body, and the threshing section is configured to handle the harvested husks that are sequentially supplied, and
The post-processed material falling and being supplied through the receiving net (11) and the post-processing material discharged through the dust outlet (4) that opens at the bottom of the terminal side of the prisoner in the handling room, A sorting section tB) equipped with a swinging sorting device that sorts the processed materials while transporting them rearward is provided from below to the rear of the handling room to constitute a threshing sorting device for a combine harvester.

The oscillating sorting device includes a grenpan (14) for sorting items from the receiving net 11) while oscillatingly feeding them.
and Glensheep (119) with a pair of left and right swinging frames H, (I
At the same time, the threshing material that falls from the dust outlet (4) after being transferred to the end of the handling room without leaking through the receiving net (1) is sorted while being oscillated. Two-stage straw hooks 11η and 0η are installed on the swing frames α and a.

The sorting section (at the bottom of the parent, there is a No. 1 processed material collecting section (5) that collects the No. 1 processed material from the sorting section +81, and a sorting section (B
No. 2 processed material collection section (6) that collects the No. 2 processed material from I
) is arranged. In addition, a winnow (7) that blows the sorting air toward the sorting section (Bl) is provided to blow away the straw waste in the sorting section (81) to the rear. This is a cross-flow fan that sucks and discharges the straw waste blown away by the winnowing machine (7) to the outside of the device.

A processing section (C) may be provided for handling and processing the No. 2 processing material collected in the No. 2 processing material collection section (6) and transported by the vertical screw conveyor (9) and supplying it to the sorting section (Bl). be.

To configure the processing section 1cI, the vane-shaped rotary body side that discharges the second processed material from the vertical screw conveyor (9) and supplies it to the sorting section +BIK is connected to the terminal end of the vertical screw conveyor (9). The vertical screw conveyor (9) is provided with an opening (11J) which communicates with the sorting part fBl to form a supply path (11) by the rotary body (1). ), and a net-like body C11 for reprocessing the processed material is provided only in the lower layer of the opening, so that the second processed material transported by the vertical screw conveyor (9) is transferred to the rotating body. By the rotation of (10), it is pressed against the reprocessing net α turbidity of the processed material so that it can be reprocessed sufficiently. is automatically pushed up and supplied from the upper layer of the opening (I) to the sorting unit fBl,
Sorting section (provided to allow light processing to prevent grain damage due to the natural processing action of Bl).

[Another example]

In the embodiment described above, the rotating body side is composed of two blades, but it may be composed of eight or more blades.

Further, in the above embodiment, a crimp net made of iron wire woven like a rice cake net was used as the net I for reprocessing the processed material, but a punched iron plate with a plurality of holes made in a thin steel plate may also be used.
