Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a sorting tube in which a receiving gutter is inserted through a sorting tube that is rotatably hung horizontally by forming a large number of recesses on the inner circumferential surface of the sorting tube. Regarding the sorting device in a grain rotary sorter that separates and separates the mixed grains into brown rice and paddy by moving the mixed grains from one end of the body toward the other end, it is particularly important to install a mixed grain receiver for the paddy side on the grain receiving side of the receiving trough. The gutter and the mixed grain receiving trough on the brown rice side are hung horizontally, and the grains received in the mixed grain receiving trough on the paddy side are placed in the middle of the sorting cylinder, and the grains received in the mixed grain receiving trough on the brown rice side are placed separately at one end. The aim is to reduce the cyclical sorting effect in a rational manner.

(Prior art) As described above, a receiving gutter is inserted into a sorting cylinder which is rotatably hung horizontally by forming a number of grooves on its inner circumferential surface, and is hung horizontally from one end of the sorting cylinder to the other. In a grain rotary sorter that separates and sorts mixed grains by flowing them toward the end side, one mixed grain receiving gutter is installed in parallel on the grain receiving side of the receiving gutter, and the grains received in the receiving gutter are It was constructed so that the mixed grains of unused brown rice and paddy were returned together to one end of the sorting cylinder for cyclic sorting. However, in the conventional device configured in this way, even the paddy that should be discharged from the inner circumference of the sorting body at the other end is returned to one end along with the brown rice, which places an unnecessary burden on the sorting body and reduces the purity of the sorting body. This had a negative impact on sorting efficiency.

(Problems to be Solved by the Invention) Therefore, the present invention aims to remove the brown rice and paddy that do not reach the inside of the receiving trough due to the scooping action of the scoop, and to remove the brown rice and paddy that do not reach the inside of the receiving trough. By dividing them into mixed grains with a high ratio of brown rice and returning them to one end side and the middle part of the sorting cylinder, the mixed grains with a high proportion of brown rice undergo a longer flow transfer process and are accepted into the receiving gutter. For mixed grains with a high proportion of paddy, the process is shortened and the paddy is discharged from the other end as quickly as possible to ensure that the paddy does not interfere with the separation and sorting action of scooping up brown rice as much as possible, thereby improving the purity of sorting. However, the aim is to improve the sorting efficiency.

(Means for Solving the Problems) Therefore, in order to rationally perform the cyclic sorting action described in the previous stage in the sorting cylinder, the present invention provides a method for moving the grain receiving side of the receiving gutter from the other end to the middle part. A brown rice side mixed grain receiving gutter extending from the other end side to one end side is installed horizontally between the paddy side mixed grain receiving gutter and the said receiving gutter, and the paddy side mixed grain receiving gutter is connected to the paddy side mixed grain receiving gutter. The grains received in the mixed grain receiving trough on the brown rice side are returned to the middle part of the sorting cylinder, and the grains received in the mixed grain receiving trough on the brown rice side are returned to one end of the sorting cylinder.

(Function) As a result, the brown rice that is scooped up by the scooping action of <K and that is scooped up at the highest level in the trench is received in the receiving gutter and taken out of the machine, but it is not stored in the receiving gutter. Mixed grains with a high mixing ratio of brown rice fall on the higher side where it cannot be accepted, and mixed grains with a higher mixing ratio of paddy fall on the lower side.

This mixed grain with a high proportion of brown rice is placed in the mixed grain receiving gutter on the brown rice side.
The mixed grains with a high mixing ratio of large-sized paddy are received in the mixed grain receiving trough on the rice side, and are returned to the inner circumferential surface of the sorting cylinder from one end side and the middle part.

Therefore, if mixed grains with a high proportion of brown rice are accepted into the receiving trough by prolonging the fluid transfer process, the proportion of brown rice in the new mixed grains fed from one end of the tank will be increased to allow separation and sorting. 17. Mixed grains with a high proportion of rice grains shorten the fluid transfer process, speeding up the discharge of rice from the other end, and promoting the separation of brown rice.

(Example) Hereinafter, the present invention will be explained based on embodiment figures.

(11 is a sorting cylinder with a large number of depressions (2) formed on the inner circumferential surface. One end (X) and the other end (y) of the sorting cylinder are connected to the drive wheel (3).

A screw conveyor +111 ilZ is installed separately from the side (Y) to one end side (X3) to open the reduction port (o>60) and to transfer the grain from the other end side (y) to the one end side (X). are doing.

In addition, a3 is a supply gutter for mixed grains that is projected into the sorting cylinder (1) at one end side (fx), (141 is a brown rice removal gutter connected to the other end (IQ (y)) of the receiving gutter (5), ll51 is a paddy removal trough that communicates with the lower inner circumferential surface of the sorting cylinder on the same side (Y).

Therefore, the mixed grains of brown rice and paddy that are sequentially supplied to one end (X) of the sorting cylinder (1) from the supply gutter (13) are as shown in Figures 2 and 4.
The brown rice in the mixed grains is transferred from one end 411 (X) to the other end (y) by the scooping action of the kuhomi (2) rotating in the direction shown by the arrow in the figure. 5) It is scooped up and separated into brown rice and paddy.

That is, brown rice, which is generally smaller in size than paddy, is <11 mm (2
), and as shown in Figure 4, the paddy falls in a parabola over the range (M). It is lifted to a high height and falls over a range of (N). In this way, the range (111) is higher than the range IN) and partially overlaps, so most of the brown rice is received into the receiving gutter (5), and even into the receiving gutter (5). The mixed grains containing a portion of paddy, that is, the mixed grains with a high mixing ratio of brown rice, are received in the mixed grain receiving trough (8) on the brown rice side.
A large amount of paddy containing a very small amount of brown rice, that is, a mixed grain with a high proportion of paddy, is received in the coarse mixed grain receiving trough (7). The brown rice received in the receiving trough (5) is transferred to the other end (Y) and then taken out of the machine from the brown rice take-out trough (141). It is returned to the middle part and the separation and sorting action is repeated, and the mixed grains with a high proportion of brown rice are returned to one end (Y) and merge with the new mixed grains supplied from the supply gutter 11m, where they are separated and sorted. , the paddy is discharged out of the machine from the other end (Y) by a paddy removal gutter 1151.

Therefore, between the one end side (X) and the middle part of the sorting cylinder (1), the so-called mixed grains with a high brown rice ratio, which are supplied from the supply gutter U3, are separated and sorted. Between the processing section and the other end (Y), a cyclical sorting action is performed to select mixed grains with a high proportion of paddy.

In addition, when the mixed grain receiving gutter (8) on the brown rice side is provided on the other end side (y) as shown by the imaginary line in Figure 1, the mixed grain receiving gutter (8) is
) can also be used to supply the inner peripheral surface of the sorting cylinder (11).

(Effects of the Invention) As described in detail above, the present invention has a number of depressions formed in the inner circumferential surface of the sorting cylinder, which is rotatably hung horizontally, and a receiving gutter is inserted therethrough and horizontally hung. In a grain rotary sorting machine that separates and separates brown rice and paddy by fluidizing mixed grains of brown rice and paddy from one end side to the other end, a middle section from the other end to the grain receiving side of the receiving trough is used. A brown rice side mixed grain receiving gutter extending from the other end side to one end side is installed horizontally between the coarse side mixed grain receiving gutter and the said receiving gutter, and the coarse side mixed grain receiving gutter is connected to the rough side mixed grain receiving gutter. The grains received in the mixed grains are returned to the middle part of the sorting cylinder, and the grains received in the brown rice side mixed grain receiving trough are returned to one end of the sorting cylinder for circulation sorting. Mixed grains with a high proportion of paddy are returned to one end, and mixed grains with a high proportion of paddy are returned individually to the middle part.The flow transfer process of mixed grains with a high proportion of brown rice is lengthened to allow the brown rice to flow into the receiving trough. In addition to promoting acceptance, the proportion of brown rice in the new mixed grains fed from one end is increased to improve separation and sorting, and for mixed grains with a high proportion of paddy, the flow transfer process is shortened and the paddy is fed from the other end. By discharging the rice as quickly as possible, it does not place unnecessary burden on the sorting cylinder unlike the conventional one, and the scooping action of brown rice is not obstructed by the paddy as much as possible7, and the separating action of brown rice is promoted to improve the sorting purity. Sorting efficiency can be improved.
