As shown in these drawings, the agricultural sorter according to the present invention includes a fixed frame 10, a plurality of sorting rods 25 arranged between a pair of circular support plates 21 at regular intervals, And a discharge guide 30 for discharging agricultural products that have passed through the space between the sorting rods 25 in the sorting drum 20 to one side of the sorting drum 20 .

The fixed frame 10 has a long rectangular frame with a plurality of elongated pipes vertically and horizontally connected to each other. In the fixed frame 10, a plurality of the sorting drums 20 are arranged in a row in the rotating direction.

The discriminating drum 20 comprises a pair of circular supporting plates 21 and a separating bar 25 provided between the circular supporting plates. The circular support plate 21 is formed in a circular plate or a ring shape, but both sides thereof may be formed into a ring shape or only one side may have a circular plate shape. This is because the discharge guide 30 has to be inserted through one side. The circular supporting plate 21 is formed with a shaft hole 22 at regular intervals. Both ends of the separating bar 25 are inserted into the shaft hole 22 of the circular support plate 21 and fixed. When the sorting rods 25 are coupled to all the shaft holes 22 as described above, they have the same shape as the circular drum. The sorting drum 20 is installed such that its axial direction is transversely installed. At least two rollers 11 are provided below the fixed frame 10 to seat the sorting drum 20 on the rollers 11. The roller 11 idles to support the circular supporting plate 21 of the discriminating drum 20 to prevent smooth rotation of the discriminating drum 20 and deformation of the discriminating bar 25. [ Here, the discriminating drum 20 may be provided so that the discriminating drum 20 rotates in the form of a cantilever shaft by forming a circular support plate 21 on one side thereof and connecting it with a horizontal shaft between the disk and the fixing frame. When the agricultural products are raised from the upper part by the sorting drum 20, the agricultural products smaller than the distance between the separating rods 25 fall into the discriminating drum 20 through the separating rods 25, Larger agricultural products are transported to one side in a state of being hooked on the sorting rods 25.

The discharge guide 30 is formed in a horizontal plate shape and is formed so as to pass through the circular support plate 21 from the inside of the selection drum 20 and be exposed to the outside and downwardly inclined to the outside direction so that the agricultural products contained in the discharge guide 30 It is naturally discharged to the outside. And an escape prevention jaw protruding from the edge to prevent the agricultural product from falling through the edge.

Two or more of the sorting drums 20 are arranged in parallel in parallel with each other, and the intervals between the sorting rods 25 of the respective sorting drums 20 are made different. That is, the intervals between the first sorting rods 25 of the first sorting drum 20 are narrow and the intervals of the sorting rods 25 are gradually widened toward the last sorting drum 20, Respectively.

The plurality of sorting drums 20 are connected and rotated by a drive motor and a power transmission device 40. The power transmission device 40 may comprise a sprocket, a chain, a pulley, and a belt. When the circular supporting plate 21 is in the form of a ring, there is no axis, so that the sprocket is brought into rolling contact with the separating bar 25, thereby rotating the discriminating drum 20 .

Further, between the discriminating drums 20, there is provided a transmitting plate 50 for smoothly guiding the agricultural products to the next discriminating drum 20. The transfer plate 50 is formed in a horizontal plate shape and is formed to be inclined downward in the conveying direction. The agricultural products that can not be passed through the sorting bar 25 by the transfer plate 50 are placed on the transfer plate 50 and then put on the next sorting drum 20.

The slanting rod 60 gradually comes close to the sorting rods 25 in the selection drum 20 just before the transfer plate 50 so that the agricultural products put between the sorting rods 25 are brought into contact with the plunger 60 And lift it up. This is to prevent the damage due to damage to the fruit when the agricultural product is brought into contact with the transfer plate 50 while being transported in a state of being positioned between the sorting rods 25. That is, the fruit placed between the separating bars 25 is lifted just before the transfer plate 50, and is naturally placed on the transfer plate 50.

The operation of the agricultural sorter according to the present invention having such a structure will be described in detail.

First, when the operator continuously raises the agricultural product on the transfer plate 50 of the first selection drum 20, the operator transfers the agricultural product to the selection drum 20 where the agricultural product is rotated by the inclined transfer plate 50. The agricultural products transferred to the sorting drum 20 are hooked and transported while being positioned between the sorting rods 25, respectively. In this process, the agricultural products smaller than the distance between the separating bars 25 are passed through the separating bars 25 to fall into the selection drum 20, and the agricultural products falling down are contained in the discharging guide 30, To be guided to the outside and put in a separate collecting box. On the other hand, the agricultural products that have not passed through the sorting rods 25 are conveyed to the next conveying plate 50. When the agricultural products that are caught between the sorting rods 25 come into contact with the pushing- And is dropped onto the transfer plate 50 at the same time, and then put on the next discriminating drum. The raised fruit is conveyed by the rotating sorting drum 20. The intervals between the sorting rods 25 of the sorting drum 20 are wider than the interval between the immediately preceding sorting rods 25, The agricultural products are collected by passing through the separation rods 25 and collecting them through the discharge guide 30. The agricultural products which have not passed through the sorting rods 25 in the sorting drum 20 are transferred to the next sorting drum 20 and are sequentially passed through and transported to the sorting drum 20.
