It is composed.

  The seed which is the granular material m dropped from the guide pipe 4 constituting the granular material replenishing apparatus is constituted by a diaphragm in the discharge pipe 9 illustrated in FIG. 7 and extending downward in an oblique direction. It is supplied to the seed retention part 10 which is a particulate matter retention part. A seed sensor B is provided on the seed retention unit 10, and when the seed sensor B no longer detects the seed, the granular material replenishing device of the present invention is activated, and a certain amount of seed is retained. It is dropped on the part 10. The seed staying part 10 is constituted by a diaphragm, and the seed staying part 10 vibrates to avoid a state where seeds are stacked, so that one grain becomes a layer on the seed staying part 10. The vibration is added so that they line up.

  The suction head Y that adsorbs seeds by the vacuum illustrated in FIG. 6 moves to move the seeds on the seed retention part 10, lowers the adsorption head Y from above the seed retention part 10 into the seed retention part 10, and The seeds arranged in a single layer in the retention part 10 are adsorbed. After the seeds are adsorbed one by one by the adsorption head Y, the adsorption head Y rises, and the adsorption head Y is further moved onto the processing unit K by the conveying device 12, and the gel agent of the processing unit K is obtained. The state of adsorption by the vacuum is released at the entrance of the gel coating hole filled with, and the seed is dropped into the gel coating hole. Thereafter, a gel is supplied around the seeds to produce gel-coated seeds. The suction head Y is provided with a plurality of suction needles, and is configured such that a plurality of seeds that are sucked one by one at the tip of the suction needle can be carried into the processing unit K.

  The gel seeds that have been formed by coating the periphery of the seeds with a gel agent then drop onto the hardening part M of the gel-coated seed processing apparatus. In the hardening part M, the liquid of the hardening agent is retained in the liquid tank, and the gel agent around the seeds is hardened while the gel seed is forcibly conveyed and passed through the hardening part M. .

  By passing through the hardening part M over a certain period of time, the hardened gel seed falls to the portion of the water washing part N below it. In the water washing section N, the gel seeds are configured to pass through predetermined washing water over a predetermined time, and the gel seeds are washed with water. The commercialized gel seed after passing through the water washing section N is stored in a gel seed retention box 14 disposed further below. In FIG. 1, the gel-coated seed processing apparatus is provided with a coated gel tank 18 and a control panel 19 as other apparatuses.

  Next, the granular material replenishing device will be described with reference to FIGS. 4, 5, 7 and 8. A support frame 15 configured in a gate shape is erected above the processing portion K, the conveying device 12 and the suction head Y in the gantry 11 constituting the base portion of the gel-coated seed processing apparatus. The lower end of the cylinder portion of the air cylinder D is fixed to the base plate 13 that forms the upper portion of the support frame 15. The upper end of the piston portion of the air cylinder D is connected to the slider base 5. The slider base 5 is engaged and fixed to a slider 6 which is a member constituting the supply hopper A.

  The air cylinder D is fixed to the base plate 13 fixed to the support frame 15, and the supply hopper A fixed to the piston side of the air cylinder D is moved up and down by expansion and contraction of the air cylinder D fixed to the base plate 13 side. It moves. The air cylinder D moves the supply hopper A up and down with respect to the guide pipe 4. That is, the piston portion at the top of the air cylinder D expands and contracts vertically, the slider base 5 constituting the replenishment hopper A is connected to the upper end portion of the piston, and the slider base 5 constitutes the slider 6 constituting the replenishment hopper A. Is engaged.

  With this configuration, when the piston portion of the air cylinder D expands and contracts in the vertical direction, the slider 6 connected via the slider base 5 moves up and down, and as a result, the refill hopper A moves up and down. A pipe joint 16 provided at the lower end on the guide pipe 4 side is fixed to a base plate 13 fixed to the support frame 15. The base plate 13 communicates the inside of the discharge pipe 9 at the lower end with the inside of the guide pipe 4 and is fixed to the support frame 15.

  Further, a gate-type support frame 15 is provided which is fixedly supported and erected on the side of the gantry 11 constituting the gel-coated seed processing apparatus. A base plate 13 is fixed to the support frame 15. Further, the guide pipe 4 is fixed to the base plate 13 with a slight backlash provided by a pipe joint 16 and a pipe fixing plate 17. The pipe fixing plate 17 is a metal fitting for fixing the lower end of the guide pipe 4 to the base plate 13, and is configured so that the guide pipe 4 can be easily removed for cleaning and product replacement. The pipe joint 16 is a joint for connecting the guide pipe 4 and the discharge pipe 9.

  In the above configuration, one end is fixed to the gantry 11 side, the upper part of the air cylinder D is connected to the upper part of the slider base 5 at the lower end of the supply hopper A, and the air cylinder D expands and contracts vertically. The replenishment hopper A moves up and down. In this embodiment, there is one air cylinder D, but since two sets of supply hoppers A are arranged on the left and right, two sets of supply hoppers A are simultaneously connected by one set of air cylinders D. It is configured to move up and down.

  On the other hand, the guide pipe 4 is fixed to the base plate 13 side of the gantry 11. That is, the guide pipe 4 is fixed to the base plate 13 by the pipe fixing plate 17, and the base plate 13 is fixed to the support frame 15 that is erected from the mount 11 and configured in a gate shape.

  The operation of the device when the granular material m of the granular material replenishing device is used as a seed is as follows. As shown in FIG. 8A, the seeds are filled in the hopper case 7 so that the seed amount level L, which is the particulate amount level, is equal to or less than the MAX seed amount line F inside the replenishment hopper A.

  The presence or absence of seeds on the seed retention part 10 constituted by the diaphragm is detected by a seed sensor B which is a particulate matter sensor. When the seed sensor B determines that “there is no seed on the seed retaining portion 10”, the replenishment hopper A rises. As a result, the replenishment hopper A stops at the uppermost point position E illustrated in FIG. At the uppermost point position E, the upper end of the guide pipe 4 is located below the seed amount level L, so that the seed can fall into the guide pipe 4.

  Since the seed pipe 4 moves up and down inside the seeds and is stirred for each seed, the bridge portion formed at the entrance of the guide pipe 4 is collapsed, and the seeds of the guide pipe 4 It is not clogged with a bridge at the entrance. Then, after the replenishment hopper A stops for a predetermined time at the uppermost position E, the air cylinder D is reduced and the replenishment hopper A is lowered.

  And the replenishment hopper A stops in the state which the position of the seed amount level L became a position lower than the front-end | tip of the induction | guidance | derivation pipe 4 like the state of (c) of FIG. The replenishment hopper A moves up and down by the air cylinder D via the slider base 5. The air cylinder D is provided with an auto switch at the uppermost point and the lowermost point. The amount of seeds introduced into the replenishment hopper A is such that the seed amount level L is lower than the tip of the guide pipe 4 with the replenishment hopper A positioned at the lower end as shown in FIG. The seed quantity level L at this position is the MAX seed quantity line F so that seeds can be introduced only up to the seed quantity level L at which the seed cannot fall into the guide pipe 4.

  As described above, as shown in FIG. 8B, the seed replenishment amount is controlled by the stop time of the expansion / contraction operation of the air cylinder D at the uppermost point of the replenishment hopper A. At this time, the seed is fed out in the direction of the guide pipe 4 along the inclined surface inside the slider 6 when the supply hopper A reaches the uppermost point position E. Since a small amount of seed is desirable rather than being fed out in large quantities, the stop time of the top point position E is adjusted to be as short as possible.

  That is, when a large amount of seed is supplied from the granular material replenishing device to the seed retention unit 10, the seed overflows on the diaphragm and the adsorption rate by the adsorption head Y decreases. The expansion / contraction operation of the air cylinder D is repeated until the seed sensor B that detects the seeds on the seed retention unit 10 determines that “there are enough seeds on the seed retention unit 10”. The seeds fed out from the guide pipe 4 pass through the discharge pipe H and fall into the seed retaining part 10 according to the inclination and are replenished.

  The operation of removing the replenishment hopper A at the time of seed variety exchange and maintenance is performed as follows. First, the urea screw of the pipe joint 16 is loosened and the pipe joint 16 is removed from the base plate 13. Next, the urea screw fixed to the slider base 5 below the slider 6 is loosened to remove the space between the air cylinder D and the slider base 5 so that the supply hopper A can be separated from the air cylinder D. Further, the pipe fixing plate 17 is loosened to disengage the base plate 13 from the base plate 13, thereby enabling separation.

  Next, when the supply hopper A and the guide pipe 4 are pulled out together, the removal is completed. Further, by removing the urea screw and removing the cap 8 at the top of the hopper case 7, the seeds remaining in the replenishment hopper A can be taken out and the inside of the hopper case 7 can be wiped and cleaned. Further, the inside of the guide pipe 4 can be cleaned and the remaining seeds can be taken out. The structure of the parts that make up the replenishment hopper A is simple, and all parts can be separated, so there is no fear of mixing with other seeds due to the presence of different species.

  The replenishment hopper A and the guide pipe 4 are attached in the reverse order. In other words, the slider 6, the hopper case 7 and the cap 8 are assembled and the guide pipe 4 is inserted.

  Next, the slider base 5 portion of the slider 6 is fixed to the air cylinder D side. The pipe fixing plate 17 is fixed to the base plate 13. The portion of the pipe joint 16 is not completely fixed with the discharge pipe 9, but has a joint structure in which the passage communicates.
