Description

[Detailed description of the invention] The present invention relates to a sorting device for a threshing machine.

A combine threshing machine or a threshing machine without a reaping section is equipped with a handling barrel for threshing shell culms, and a sorting device for sorting threshed grains and processed materials generated during threshing. The grains threshed by the handling barrel pass through the mesh of the handling and receiving net and fall onto the sorting net of the sorting device, and the shaking of the swinging shelf that supports the sorting net and the sorting wind generated by the winnowing machine. After being sorted, they are transported and collected on the 1 Homare spiral conveyor. On the other hand, straw waste, scraps, and processed materials from Kagimata Misaki generated during threshing are handled together with some of the grains, transported through the house, and become waste matter from the dust outlet at the end of the house and then stored in the swing shelf. It falls onto two strokes. The fallen dust is removed by the swinging of the swinging shelf.
The grains are sorted by the sorting wind from the winnowing machine and the suction by the suction fan.As a result of the sorting, some of the grains are recovered and light straw waste, dust, etc. are discharged outside the machine by the suction fan. The remaining waste, so-called 2-scented products, falls onto the 2-scented spiral conveyor and is conveyed, and then the 2-scented product rotates at the end of the transfer.
The grain is scraped up by the plate of the plow grain machine, lifted up and conveyed inside the No. 2 reduction cylinder, and returned to handling fatigue. It joins the 31 substances that are reduced and transferred into the fc2 fragrance L1 handling chamber, and the sorting process is repeated.

Conventionally, in the sorting device of a threshing machine that operates in this way, the suction fan is generally in the casing! ! There is also a funnel-shaped space that opens only upwards between the upper surface of the 2-book original letter facing the handling chamber, the side plate of the frame, and 0. As a result, some of the dust that is being sucked in by the suction fan and trying to be discharged outside the machine, as well as grains that are blown up by the sorting wind, fall and accumulate in this space, which then flows into the swinging shelf. There was a problem in that the quality of grains deteriorated by falling and mixing with grains that had already been sorted, resulting in loss of 9p of grains that were lost or piled up.

The present invention has been made in view of the above-mentioned points.4 The cylindrical casing of the suction fan has an opening above the main cylinder, and is surrounded by this opening, the upper surface of the main cylinder, and the side plate of the frame. By installing a sorting sink plate in the viewing section that directs the falling direction toward the No. 2 spiral conveyor, the grains in the dust that is about to accumulate on P1 are re-sorted, improving the crystallinity of the grains and increasing the grain size. This invention provides a sorting device for a nine-threshing machine that measures reduction. Embodiments of the present invention will be described in detail below with reference to the drawings.

The suction box swing part of the frame side plate 21 is formed in an inclined shape as shown in FIG. A funnel-shaped space 24 is formed.

Next, in the suction box 5, there are a plurality of scratches 1i on the narrow surface! j
A short and small raking cylinder 26 with 25 implanted therein is mounted on a shaft corresponding to the rear of the waste outlet of the sieving Asahi 3, and the waste generated during threshing and discharged from the dust outlet is passed through the sieve line 14. It is configured to be pulled in the direction of. Furthermore, the suction box 5 includes a side plate 5&, a casing cylinder 27 formed in a semicircular arc shape,
A cylindrical suction casing 2 with bottoms on nine sides is formed surrounded by a casing side plate 28 that partitions the suction box 5 in one direction.The casing side plate 21IIK has a circular suction opening opened and a lower end A dust exhaust port 30 that opens to the outside of the machine is connected to the rearward opening. Inside the suction casing 2s configured in this way, a suction fan 32 having a plurality of blades and driven by a belt 31 to rotate in the direction shown by an arrow G in the figure is housed while being pivotally supported by the frame side plate 21. At the end of the shaft outside the machine, there is provided a tension cover type clutch device consisting of a tension pulley 34 pivotally connected to a tension pulley 33 and an operating lever 35 feet.

The suction casing 29 is opened to the space 24 above the 2-story reduction cylinder 22, and inside the space 24, a 5-story Fi suction box is integrally provided. The sink plate 3@ is engaged. This sink board 3
6 is formed in a triangular shape and the proximal edge is connected to the casing @ plate 2
There are 11 pieces in 1 and 1, and a sealant such as felt is pasted on the part where it touches the front board.

Furthermore, in the space 241m, there is a stream for sorting material (7 plates 3
7 is provided with its three sides attached to the frame side plate and the double-sided cylinder 22. 1 The insertion edge of the sink plate 36 is joined to the flat surface of the sink plate 3T so that there is no gap, and a sealing material such as felt is pasted to this joint. Formed in this way, the spin sink plate 36.3
7 slides the sorted materials such as dust and grains falling from the suction casing 29 for re-sorting. The direction of inclination is set so that it falls toward 17.

The operation of the threshing machine configured as above will be explained. The grains threshed by the handling cylinder T pass through the mesh of the handling room receiving net 9 and fall onto the sorting net 12, where they are sorted by the swinging of the swinging shelf 10 and the sorting wind from the winnowing rack 19. .

The sorted grains fall onto a single-flavor spiral conveyor 16,
It is transferred laterally and then collected. On the other hand, during threshing, a large number of waste materials such as straw waste, ears of ears, and kimata are generated, and these processed materials are transferred in the axial direction of the handling cylinder 7 through the handling mechanism 3, and then become waste materials and end up at the end of the transfer. It is discharged backwards from the glandular opening in the bulge. Since the raking jii 126 is rotating at that point, the excreted footwear is raked in by this and falls onto both lines 14, causing the swinging of the swinging shelf 10, the sorting wind from the winch 15, and the suction fan 32. Sorted by suction. As a result of this sorting, some of the grains are sorted and collected after sliding inside the swinging shelf 10, and light straw debris and cliff dust are sucked into the suction 7-an 32 and discharged from the dust outlet 30 to the outside of the machine. After sorting, the remaining waste products become so-called 211 products, which fall between the m*14 strings onto the two-way spiral conveyor 17, and are transported in the lateral direction. The transported second grain is scraped up by the blades of the rotating 211M grain machine 19, lifted up and conveyed inside the two-shojigen cylinder 22, and returned to the handler 3 from the Dokuguchi 23, where it is transported. The above-mentioned sorting is repeated with the processed materials.

In such a threshing operation, as described above, the grains and dust are blown up by the sorting wind from the winnowing machine 15 and the suction wind from the suction fan 32, and some of them fall down.
l! However, in this device, the suction casing 2g is opened at the lower end of the pipe, and a flow plate 36, 37 is placed in the space 24 so that the falling direction of the sorted material is Since it is installed so that it is directed toward the No. 2 spiral conveyor IT, the sorted materials such as grains and dust slide down from the opening onto the sink plate 36, collide with the sink plate 3T, and pass through the second spiral conveyor IT.
It is discharged onto the spiral conveyor 1T. The discharged sorted material joins the second material being transferred and is re-sorted, so there is no loss or dust falling within 1° of the swinging shelf and getting mixed into the grains. In addition, since the wedge-shaped corners of the space 24 are diagonally closed off by the sink plates 37, grains, dust, etc. do not accumulate there.

Although the present embodiment shows an example in which the sink plate 36 and the sink plate 37 are separated, they may be integrally formed and fixed to either the suction box 5 side or the frame 2 side.

As is clear from the above description, in the sorting device for a threshing machine according to the present invention, the cylindrical casing of the suction fan is opened above the second reducing machine, and this opening is connected to the upper surface of the second reducing machine and the frame side plate. By installing a sorting flow plate that directs the falling direction toward the No. 2 spiral conveyor in the space surrounded by The grain is discharged from the opening of the suction casing through the sink plate onto the two-way spiral conveyor, eliminating the accumulation of materials to be sorted and the mixing of dust into the sorted grains, improving the quality of the grains and reducing grain loss. The effects are great, such as being able to
