Abstract

The present invention relates to an apparatus for sorting crops. The apparatus comprises a vibration frame on an upper portion of a work stand. A sorting unit including a rotation rod unit rotated by being estranged in a radial direction is installed on an upper portion of the vibration frame. A power transfer unit which transfers power to the sorting unit is installed on an upper portion of the work stand. A vibration apparatus is installed between the work stand and the vibration frame. Crops are moved along first and second rotation rods of the rotation rod unit by rotating the rotation rod unit in a forward direction and a reverse direction while vibrating the vibration frame by the vibration apparatus. The crops are sorted in each size by being dropped in a space between the first rod and the second rod which are proportional to the diameter size of the crops while moving the crops. The sorting works for various crops are available by moving both ends of the second rotation rod in the sorting unit to an upper direction or a lower direction or by moving one end of the second rotation rod to the upper direction or the lower direction.

Patent Document 1 discloses a conventional crop selection apparatus, which comprises a stationary frame, a feed unit installed above the stationary frame and guiding the introduction of crops, A sorting unit forming a discharge guide bar for guiding the movement of the crops; and a conveying unit including a conveying bar provided close to below the sorting unit and pushing the cropped product between the discharge guide bars forward, And a sorting guide for guiding the interval between the transfer bars of the transfer unit to be gradually widened.

Here, when the driving unit is operated, the driving motor of the driving unit is operated, and the driving shaft and the driving gear, which have received the power of the driving motor, are rotated to circulate the driving chain.

At this time, the first and second feed gears formed on the same axis as the drive gear and the driven gear are rotated and moved to move the feed orbit, so that the feed orbit is circulated through the first and second guide pulleys.

In particular, as the inclined body of the circulating operation track is moved along the inclined picking guide at a predetermined angle, the inclined body is gradually moved downwardly while being inclined downward, and the gap between the transporting bars is widened.

Then, the conveying bar of the conveying orbit is moved to push the crop exposed downward in a state of being unfolded in the discharge guide bar, so that the crop moves forward, and thereby, in the space between the conveying bar and the discharge guide bar proportional to the diameter of the crop, Falls downward and crops are sorted by size.

However, the above crop selection apparatus has the following problems.

First, there is a friction force between the agricultural product pushed out by the transport bar and the discharge guide bar, thereby damaging the outer surface of the crop, and depending on the degree of exposure of the crop below the discharge guide bar, the transport bar can not reach the crop, , There is a problem that the crop remains in a predetermined position between the discharge guide bars for a long time and hinders the movement of another crop.

Secondly, due to the above-mentioned problem, a plurality of crops are unfolded on one line, which makes it difficult for the transport bar to push out the crops. As a result, friction between the drive gears and the driven gears and the feed- There is a problem that excessive pressure is applied to the transport bar pushing the crop, and the driving part is damaged.

The crop separator according to the present invention having the above structure is used as follows.

First, the vibrating device 500 is operated to apply vibration to the vibrating frame 200, and in this state, the power transmitting part 400 is driven to rotate the rotation bar part 310 of the sorting part 300.

At this time, the vibration device 500 applies vibration to the vibration frame 200 while being fixed to the work platform 100, thereby generating vibration in the vibration frame 200.

Particularly, the vibration frame 200 is supported by the air spring 110 installed on the upper surface of the work table 100, so that it is prevented from transmitting an impact to the work table 100 due to the elastic force of the air spring 110 will be.

The power transmission unit 400 transmits the driving force of the driving motor 411 to the rotation shaft 412 and transmits the rotation force transmitted to the rotation shaft 412 to the sorting unit 300 To the first and second rotating rods 313 and 316 of the rotating shaft 310 to rotate the rotating rod 310.

At this time, the driving motor 411 is repeatedly operated continuously in a forward or reverse direction with a time difference to determine the forward and reverse rotations of the first and second rotating rods 313 and 316.

When crops are poured or knocked over the rotation bar 310 of the sorter 300, the crops are put in the space between the first and second rotation bars 313 and 316 of the sorter 300, 1 and the second rotating rods 313, 316, respectively.

At this time, both ends of the first and second rotation bars 313 and 316 are closed by the first and second support frames 311 and 314, and the first and second connection frames 312 and 314 connecting the plurality of first support frames 311 And a second connection frame 315 connecting the plurality of second support frames 314.

When it is desired to adjust the distance between the first and second rotation bars 313 and 316 of the sorting unit 300 according to the kind or size of crops, the second connection frame 315 and the dust- The bolt 331 is moved downward by pressing the bolt 331 with the nut 332 fixed to the vibration frame 200 to press the second connection frame 315.

Then, the second connection frame 315 is moved downward to move the second rotation bar 316 downward, so that the second rotation bar 316 is moved downward while maintaining the horizontal state, The distance between the rotation bar 313 and the second rotation bar 316 is increased.

Particularly, when the user desires to move one end of the both ends of the second rotation bar 316 downward, the vibration springs 320 at either end of the both ends are press- 2 connecting frame 315. [0051]

The second support frame 314 is moved downward by the second connection frame 315 so that either one end of the both ends of the second rotation bar 316 is moved downward, 316 have a predetermined inclination angle, and at the same time, the gap between the first and second rotating rods 316 spreads upward and downward.

Here, it is preferable that one end of the second rotating rod 316 in the opposite direction in which the crop is poured or tamped is moved downward to separate the gap between the first and second rotating rods 313 and 316

The belt 413 is connected to the second rotation bar 316 which is moved downward and is shorter than the belt 413 connecting the first rotation bar 313 and the rotation shaft 412 to the belt 413 ). ≪ / RTI >

The structure for sorting the crops by dropping the crops in the predetermined sections of the first and second rotating rods 313 and 316 of the radial spreader 300 is as follows. The vibrating frame 200 is vibrated by the vibrating device to move the crops so that the crops are uniformly moved regardless of the size and the uniform movement of the crops causes the crops Overhead does not remain on the line, and there is no overload in the process of moving crops in a vibratory fashion and pushing crops out.
