Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a grain flow board in the air sorting section of a grain conditioner that guides the material to be sorted into a sorting air path. In particular, the present invention seeks to facilitate cleaning and inspection of the air sorting section, especially the inside of the sorting air duct and related components of the sorting air duct.

(b) Conventional technology The grain flow board that guides the material to be sorted through the sorting air path as described above is conventionally fixed in an inclined operating position, or by applying vibration to the operating position. The structure was designed to promote the flow down and dispersion of the material to be sorted, or to change the direction of the wind from one side to the other by changing the attitude.

Therefore, the sorting air passage has only a drop opening through which the material to be sorted flows down into the sorting air passage, and therefore the sorting air passage and its related components, such as a grain removal gutter for taking out the grains after wind selection, are opened. Cleaning and inspection work was difficult. For this reason, there are some methods that attempt to remove the remaining grains in the grain removal gutter by constructing the bottom of the removal gutter so that it can be opened and closed freely, but this is not sufficient, especially for grains. When the regulator is put into operation after being stored for a long period of time, the sorting air passages and related components become clogged, causing various troubles.

(c) Problems to be Solved by the Invention As described above, the present invention aims at fixing the grain flow plate in the conventional type in an inclined operating position, or by applying vibration to the grain plate in this operating position. Because the structure is designed to promote flow and dispersion, or to switch the wind direction from one side to the other by changing the attitude, This was created in view of the fact that it is difficult to clean and inspect the related components such as the grain extraction gutter, which can cause clogging of these sorting air channels and related components, causing various troubles. Not only the drop port for the material to be sorted but also the grain opening is widened by changing the attitude of the flow board, and this opening point and related components such as the grain extraction gutter from which the grains after wind sorting are taken out and the side wall of the machine body. By arranging the positions of the cleaning ports opened in the grain conditioner, cleaning and inspection of the grain conditioners will be made extremely easy, and the purpose is to eliminate troubles especially when starting operation of the grain conditioner after long-term storage. .

(d) Means for Solving the Problems In order to achieve the above object, the present invention is configured as follows.

That is, the grain flow plate that guides the material to be sorted into the sorting air path is formed into a substantially triangular shape when viewed from the side, the upper surface thereof is an inclined grain flow surface, and the lower surface is the top plate of the sorting air path. In addition, it is configured so that it can be switched from an operating position to a non-operating position in which a portion corresponding to the top plate of the sorting air passage is opened by rotating about an appropriate place as a fulcrum, and the grain flow plate is positioned. A grain take-out gutter for taking out grains after air sorting was installed horizontally below the sorting air passage, and a cleaning port with a lid was opened in the side wall of the machine body adjacent to the flow plate.

(E) Function With this configuration, during operation, the grain flow plate is placed in the operating position, and the material to be sorted is guided into the sorting air passage with the grain surface on the upper surface of the grain flow board for wind selection. The grains are taken out of the machine using the grain removal trough. When the operation is finished, the grain flow board in the operating position is rotated and switched to the non-operating position, and the lower surface of the grain flow board, which also served as the top plate of the sorting air path, is displaced from the position corresponding to the top plate to the open side. The sorting air passage will be wide open, and the operator will put his/her hand in through the cleaning opening opened in the side wall of the machine and use the open area to clean the inside of the sorting air passage and related components such as the grain removal trough. Cleaning and inspection can now be carried out extremely easily and reliably.

(f) Examples The present invention will be explained below based on the drawings of examples.
The grain conditioning machine shown in this example diagram is a huller, and its outline will be described first. A husking section A is provided at the front part of the top, and a pot-hole rotary sorting section C is arranged at the rear part, and these parts are integrated on a machine base 1 to constitute a hulling machine.

The husking section A consists of a paddy tank 2 and a pair of husking rolls 3 that rotate at different speeds below the paddy tank 2, and the wind sorting section B wind-sorts the scraped matter from the husking section A at the front to separate the rice into husks. By removing dust and rice grains, we obtain mixed rice of brown rice and paddy.
At the rear, the brown rice sorted by the pot-hole type rotary sorting section C is wind sorted to remove waste rice. The pot hole type rotary sorting unit C is two sorting units in which a receiving gutter 6 and a supply gutter 7 are inserted and horizontally suspended in a sorting cylinder 5 which has a large number of pot holes 4 formed on its inner circumferential surface and is rotatably suspended horizontally. C1 and C2
are arranged one above the other so that the mixed rice of brown rice and paddy obtained at the front part of the wind sorting section B is sorted into brown rice and paddy in each of them.

So, let's talk about the means of connecting the above parts.
Reference numeral 8 designates a mixed rice distribution box, the lower part of which is branched, one side communicating with the supply gutter 7 of the upper sorting section C1, and the other side extending downward and communicating with the supply gutter 7 of the lower sorting section C2. An equalizing valve 10 with a weight 9 is provided above the branching part to distribute the mixed rice while slightly accumulating it in the mixed rice distribution box 8. 11 and 12
is a brown rice removal gutter, the brown rice removal gutter 11 communicates with the receiving gutter 6 of the upper sorting section C1, and the brown rice removing gutter 12 inherits the brown rice taken out from the brown rice removal gutter 11, and also serves as the receiving gutter of the lower sorting section C2. The brown rice that is communicated with the gutter 6 and sorted in each of the drains is led out onto an outflow plate 13 provided obliquely at the rear of the wind sorting section B. Numerals 14 and 15 are paddy return troughs, and the paddy return trough 14 receives the paddy flowing out from the inner peripheral surface of the upper sorting barrel 5 and returns it to the paddy tank 2. The paddy scooped up by grain lifting buckets 16 equally distributed around the circumference is received and returned to the paddy tank 2. Incidentally, reference numeral 17 denotes a drop opening for supplying mixed rice to the sorting cylinder 5 on the rear side of each supply gutter 7.

Reference numeral 8 is an elevator, which lifts the mixed rice of brown rice and paddy obtained in the wind sorting section B to the mixed rice distribution box 8 on the front side, and the brown rice from which waste rice has been removed in the wind sorting section B on the rear side. It is designed to be lifted up and taken out to a suitable location outside the aircraft. Further, 19 is a mixed rice take-out gutter that supplies mixed rice to the front side of the elevator 18, 20 is a grain take-out gutter that supplies brown rice to the rear side of the elevator 18, and 21 is a waste rice take-out gutter that takes out scrap rice to the outside of the machine. It is a gutter, and 22 is its outlet.

Next, the main parts of the present invention will be described. A suction dust extractor 23 and a pressure fan 24 are installed before and after the wind sorting section B, and a sorting air passage 25 for wind-selecting the debris from the shedding section A is installed at the front, and the outflow plate 13 is installed at the rear. Each of them forms a sorting air passage 26 for wind-selecting the brown rice drawn out from above.

Reference numeral 27 denotes a grain flow plate having a substantially triangular shape when viewed from the side, with a drop opening 28 formed by the lower end of the outflow plate 13 and an inclined grain flow surface on the upper surface. It also serves as the top plate. Then, the front end of the grain flow plate 27 is attached to the left and right side walls of the machine body 29 and rotated from the working position shown in FIG. 1 to the flow board 13 side as shown in FIG. 4, so that it stands inverted. The grain removal gutter 20 is installed horizontally below the sorting air passage 26 portion where the grain flow plate 27 is located. Further, the bottom plate 30 connected to the front side of the grain removal gutter 20 to form the sorting air passage 26 is configured to be rotatable by having its front end connected to the left and right side walls by means of 31.

This grain flow board 2 covers a range in which the grain flow board 27 changes from the operating position to the inverted non-operation position.
