Description

[Detailed description of the invention] Industrial field of application The present invention provides a grain conditioning machine equipped with a wind screening section that forms screening air passages in two stages, upper and lower, and separates the grains separately.
This invention relates to a residue removal device for removing grains remaining at the bottom of a horizontally installed removal gutter for removing the sorted materials in a sorting air path.

In particular, the present invention has been devised to make it extremely easy and convenient to take out the residue in the upper take-out gutter.

Conventional technology Conventionally, this kind of means is known in which the bottom of a take-out gutter is configured to be openable and closable to take out the residue. There is no structure in which the bottom of the take-out gutter and the lower bottom plate from which the sorted material is taken out can be opened and closed to take out the residual material.

Problems to be Solved by the Invention The inventive device differs from the conventional structure described above in that it has a two-stage screening air path, upper and lower, and is equipped with an air selection section that separates each airflow separately. If the bottom of the upper take-out gutter is opened, the residue will not only fall into the lower sorting air passage and cannot be taken out, but will also obstruct the flow of sorting air in this sorting air passage. be.

From this point of view, the present invention attempts to easily and appropriately take out the grains remaining in the upper take-out trough.

Means for Solving the Problems Therefore, in the present invention, in a grain conditioner equipped with a wind sorting section that forms two upper and lower stages of sorting air passages and separates each part separately, the grains are sorted in the upper sorting air passage. In order to take out the sorted materials, the bottom of the take-out gutter installed horizontally can be opened and closed, and the part of the bottom plate forming the lower wind selection channel, which corresponds to the bottom of the take-out gutter, can be opened and closed. This makes it impossible to easily and appropriately take out the grains remaining in the upper take-out trough.

Function With this configuration, the sorted materials in the upper sorting air passage are transported sideways from the take-out gutter and taken out of the machine, but if the operation is stopped when the work is completed, Grain remains in the extraction gutter. To take out this residue, first open the part of the bottom plate directly below the take-out gutter that forms the lower sorting air path, and then open the bottom of this take-out gutter so that it falls from the take-out gutter and passes through the lower sorting air path. Accumulates at the bottom of the aircraft. In this case, the bottom of the take-out gutter and the bottom plate of the sorting air path may be opened at the same time. Furthermore, if this removal is carried out without stopping the operation, the residual material falling from the removal gutter will be screened out by the screening air flowing in the lower screening air passage. Moreover, at this time, outside air can also be taken in from the open portion of the bottom plate forming the lower screening air passage, increasing the wind force and increasing the air selection effect.

Embodiment The present invention will be explained below using a rice huller shown in the embodiment diagram. A is a dehulling section, B is a wind sorting section, C is a pothole type rotary sorting section, and the front part above the wind sorting section B is The rice hulling machine is constructed by arranging a mulch removal section A and a pot-hole type rotary sorting section C at the rear.

The dehulling section A consists of a paddy tank 1 and a pair of dehulling rolls 2, and sequentially dehulls the paddy supplied to the paddy tank 1.

The pot-hole type rotary sorting section C has a rough sorting section C ₁ and a fine sorting section C ₂ superimposed on the top and bottom, and the mixture of brown rice and paddy that has been dehulled and air-sorted by the dehulling section A and the wind sorting section B is collected in the upper stage. The rough sorting section _C1 performs a rough sorting, and the roughly sorted materials are then carefully sorted in a lower fine sorting section _C2 .

Both the coarse sorting section C ₁ and the fine sorting section C ₂ have receiving channels 6 and 7 that are inserted horizontally into sorting cylinders 4 and 5 that are rotatably hung horizontally with a large number of potholes 3 formed on the inner peripheral surface. The mixture of brown rice and paddy is sorted out on racks.

The wind sorting section B uses the suction air of the suction fan 8 to wind-select brown rice from the sorting section C2 at the front of the upper sorting air passage 9, which sorts the waste from the milling section _A , and at the rear. A lower sorting air passage 10 is provided which communicates with the suction fan 8 through the lower side of the upper sorting air passage 9.

Reference numeral 11 denotes a take-out gutter installed horizontally to take out the mixture of brown rice and paddy that has been wind-selected in the upper sorting air passage 9, and in front of it is a grate take-out gutter 12 installed horizontally, and at the rear is a lower tier. A horizontal gutter 13 is provided to take out the brown rice sorted by the sorting air passage 10, and the bottoms of the take-out gutter 11 and the horizontal gutter 13 are opened over the entire width, and a rotating groove is provided in front of the opening. Freely movable horizontal shafts 14, 15 are provided, and opening/closing plates 16, 1 are attached to these.
7 are pivotally connected to each other so as to be slidable, and the above-mentioned opening can be freely opened and closed.

Reference numeral 18 denotes a bottom plate that forms the lower sorting air passage 10 on the front side, and a large opening 19 is provided across the entire width of the bottom plate 18 at a location directly below the bottom of the takeout gutter 11. A rotatable horizontal shaft 20 is provided on the rear side of the 19 part, and a closing plate 21 is pivotally attached to this, so that the opening 19 can be opened and closed.

22, 23, 24 are the above horizontal axes 14, 15 and 2
The arm rods protrude from the ends of 0 and 25, and the operating lever 25 has its lower end pivoted to the machine wall.
An arm 26 protrudes from the lower end of 5. And each arm rod 22, 24 and 23 and arm 26 mentioned above.
The free ends of are connected to each other by connecting rods 27, 28, 29.

Reference numeral 30 denotes a tension spring that constantly pulls the operating lever 25 rearward. Note that 31 and 32 indicate receiving boxes, and 33 is an opening that allows the receiving boxes 31 and 32 to be freely inserted and removed.

Therefore, since the operating lever 25 is pulled rearward by the tension spring 30, it is connected to the opening/closing plates 16, 17 via the connecting rods 27, 28, 29, the arm rods 22, 24, 23, and the arm 26. Occlusion plate 21
is biased toward the side that slides upward, and the bottom openings of the take-out gutter 11 and the cross-feeding gutter 13 and the opening 19 of the lower sorting air passage 10 are maintained in a closed state. (Refer to the state shown by the solid line in Figures 1 and 3.) In this state, the unhulled material falling from the unhulling section A as shown by arrow A and the brown rice supplied from screening section C ₂ as shown by arrow B. are the upper and lower two stages of each sorting air passage 9, 10.
The rice is sorted separately at the husks, where the hulling and sorting work is carried out.

Therefore, if the operation is stopped at the end of the hulling operation, grains will remain in the take-out gutter 11 and the cross-feeding gutter 13. If you tilt it forward against the
24, 23, the arm 26, the opening/closing plates 16, 17, and the closing plate 21 are interlocked to form the state shown in phantom lines in FIG. 19 is open at the same time and take out gutter 1
The residual material in the cross-feeding gutter 13 passes through the lower sorting air passage 10 and is stored in the receiving box 31, and the residual material in the cross-feeding gutter 13 is collected as is in the receiving box 32.

Incidentally, if the residual matter is taken out from the above-mentioned take-out gutter 11 without stopping the operation, it will be sorted by the sorting air in the lower stage. At that time, outside air is also sucked in through the opening 19, increasing the wind force and allowing sorting.

Effects of the invention As detailed above, the present invention provides a grain conditioner equipped with a wind sorting section that forms two upper and lower stages of sorting air passages and separates the grains separately. The bottom of the take-out gutter installed horizontally for taking out the sample is openable and closable, and the part of the bottom plate forming the lower sorting air passage corresponding to the bottom of the take-out gutter can be opened and closed. The effects listed in can be achieved.
That is, (a) Removal of the sorted material sorted in the upper sorting air passage The residue in the gutter can be easily and appropriately taken out.

(b) When removing the residue from the above-mentioned extraction gutter, the residue can be removed while being sorted by the sorting air flowing through the lower sorting air passage, and at this time, the bottom plate forming the lower sorting air passage can be removed. It is possible to draw in outside air from the open areas and increase the wind force, thereby increasing the wind selection effect.

(c) Furthermore, if configured as in the embodiment, the residues sorted in the upper and lower two-stage sorting air passages can be taken out at the same time using one operating lever.

As a result, when the bottom of the upper take-out gutter is opened, the residue does not fall into the lower sorting air passage and cannot be taken out, unlike in the conventional case. This does not impede the flow of the sorting wind.
