  According to the invention of claim 2, in addition to the effect of the invention of claim 1, the seeds can be dried evenly while further improving the drying efficiency.

One embodiment of the present invention will be described below.
The seed disinfection equipment is provided with a hot water disinfection device A, a seed cooling device B, and a drying device C in order from the previous process to the subsequent process. The hot water disinfection apparatus A is provided with a box-shaped hot water disinfection tank 1, and a circulating transfer apparatus 3 for circulating and transferring a large number of seed buckets 2 is provided above the hot water disinfection tank 1. In addition, the said hot water disinfection tank 1 becomes a structure which can accommodate 11 seed buckets 2 in a row. In addition, the seed bucket 2 is configured to contain a net-like seed bag P for storing seeds for each predetermined amount.

  The circulating transfer device 3 has a lowering device 3d for lowering the seed bucket 2 which forms a large number of holes on the transfer start end side and immersing the seed bucket 2 in the hot water in the hot water disinfection tank 1, and a seed immersed in the hot water disinfection tank 1. A transfer device 3a for transferring the bucket 2, a raising device 3b for raising the seed bucket 2 immersed in the hot water disinfection tank 1 on the transfer end side, and a seed bucket 2 raised by the raising device 3b to the lowering device 3d And a return device 3c.

  The transfer device 3a includes a guide rail portion 4 that receives an edge portion 2a provided at the upper end of the seed bucket 2 from the lower left and right sides, and a chain-type transfer conveyor 5 for transferring the seed bucket 2 at the transfer start end portion. Provided. As shown in FIG. 3, the transfer conveyor 5 includes a pressing protrusion 5 a that transfers the seed bucket 2 to an appropriate position in the circulation path, and the pressing protrusion 5 a is fixed to the left and right sides of the edge of the seed bucket 2. The seed bucket 2 is transferred by pushing the fixing shaft 2b in the transfer direction, the seed bucket 2 on the lower transfer side is sequentially pushed by the seed bucket 2 on the upper transfer side, and the seed bucket 2 is transferred in the hot water disinfection tank 1 It has been configured to be.

  As shown in FIG. 4, the ascent device 3 b is provided with a chain-type ascending conveyor 6 provided with lifting protrusions 6 a on which the fixed shaft 2 b of the seed bucket 2 at the end (transfer end) of the guide rail portion 4 is hooked. Yes. Therefore, by driving the lifting conveyor 6, the fixed shaft 2b of the seed bucket 2 at the terminal end (transfer terminal) of the guide rail portion 4 is lifted by the lifting projection 6a, and the seed bucket 2 is lifted.

  Further, as shown in FIG. 4, the ascending conveyor 6 has an oblique movement path (circulation) that moves in the transfer direction of the transfer device 3a as the seed bucket 2 is raised from the rising start end position where the lifting projection 6a is caught by the fixing shaft 2b. It circulates in a triangular circulation path in a side view with a path. A fixed reversing cam 7 for reversing the seed bucket 2 in the middle of the oblique movement path is provided on the left and right, and when the seed bucket 2 is lifted, the reversing cam 7 is fixed on the edge 2 a of the seed bucket 2. The roller 7a on one side (the transfer direction side of the transfer device 3a, the seed cooling device B side) 2b is pressed down from the upper side, so that the seed bucket 2 is seed-cooled with the fixed shaft 2b as a fulcrum. The seed bag P is inverted so as to face the device B, and the seed bag P in the seed bucket 2 is discharged to the cooling bucket 8 of the seed cooling device B.

  Further, as shown in FIG. 4, an oblique movement path (circulation path) that moves in the transfer direction of the transfer device 3 a as the seed bucket 2 of the ascending conveyor 6 is moved up to the fixed reversing cam 7. .. Are fixedly arranged at predetermined intervals, and when the ascending conveyor 6 moves upward, the roller 7a on the seed bucket 2 side and the fixed vibrating rollers 7b,. The seed bucket 2 is vibrated.

  According to the said structure, the seed bucket 2 can be vibrated up and down, reducing a vibration load, taking out warm water can be reduced, and the fuel cost for heating hot water can be saved. Moreover, the temperature rise of the cold water of the cooling tank 10 can be reduced.

  In addition, as shown in FIG. 7, the guide plate 9 which guides the hot water which drops from the seed bucket 2 which rises or reverses to the hot water disinfection tank 1 from the upper end of the hot water disinfection tank 1 to the position of the reversing cam 7 is provided. By this guide plate 9, the hot water dripping from the seed bucket 2 is returned to the hot water disinfection tank 1 to suppress the release of heat in the hot water disinfection tank 1, and the hot water dripping into the cooling tank 10 of the seed cooling device B. Decrease in cooling efficiency can be prevented. The reversing cam 7 has a configuration in which a plurality of (two) rollers are provided at different positions. When the seed bucket 2 is lifted, one of the rollers comes into contact with the seed bucket 2 from above to tilt the seed bucket 2. Then, when the one roller is separated from the seed bucket 2, the seed bucket 2 swings to cut off the hot water in the seed bucket 2, and then the other roller contacts the seed bucket 2 from the upper side to remove the seed bucket 2. The seed bucket 2 is turned upside down so that the seeds in the seed bucket 2 are supplied to the seed cooling tank 10 side.

  The return device 3c and the lowering device 3d are configured so as to include a chain-type return conveyor 11 provided on the left and right with a transport protrusion 11a on which the fixed shaft 2b of the seed bucket 2 is hooked. As shown in FIGS. 3 to 6, the transport protrusion 11a is disposed opposite to the front and rear in the circumferential direction of the return conveyor 11, and is configured to hold the fixing shaft 2b between the front and rear protrusions 11a. ing. Therefore, after the seed bucket 2 that has been raised to the upper end of the raising conveyor 6 of the raising device 3b is taken over by the return conveyor 11 and laterally moved to the transfer start end side of the transferring device 3a, the seed bucket 2 is lowered and is in the middle of the lowering path. At the seed bag supply position r. At the seed bag supply position r, the seed bucket 2 is positioned above the hot water disinfection tank 1, and an operator supplies the seed bag P to the seed bucket 2. When the transfer device 3a is actuated to create a space for accommodating the seed bucket 2 at the transfer start end, the return conveyor 11 is actuated to lower the seed bucket 2 at the seed bag supply position r, It is dropped and supplied from the lower end of the return conveyor 11 to the hot water disinfection tank 1. Note that the seed bucket 2 waiting at the seed bag supply position r is inclined such that the lower front side contacts the guide 12 attached to the hot water disinfection tank 1 and the upper opening portion faces the front side. Thereby, an operator can supply seeds (seed bags P) to the seed bucket 2 easily. Further, since the seed bucket 2 is tilted, the seed bucket 2 can be set to a height at which the seed bucket 2 is not immersed in the hot water of the hot water disinfection tank 1 and the height of the opening of the seed bucket 2 can be set as low as possible. It is easy to supply seeds (seed bags P) to the bucket 2.

  Further, when the seed bucket 2 at the seed bag supply position r is lowered and dropped from the lower end of the return conveyor 11 to the hot water sterilization tank 1, the edge 2a of the seed bucket 2 collides with the guide rail portion 4 to generate noise. There is a possibility that the edge 2a is deformed due to the occurrence or impact. Therefore, the ridge raised on a part of the bottom surface of the hot water sterilization tank 1 so that the bottom of the seed bucket 2 contacts the bottom surface of the hot water sterilization tank 1 before the edge 2a of the seed bucket 2 collides with the guide rail part 4. If the bottom part of the seed bucket 2 that falls on the raised part first comes into contact with the raised part, the impacting sound is suppressed because the colliding part is underwater, and the edge 2a is prevented from being deformed and circulated and transferred. The transfer of the seed bucket 2 by the device 3 can be optimized.

  The transfer device 3a intermittently transfers a plurality of seed buckets 2 simultaneously, whereas the return device 3c and the lowering device 3d continuously transfer a single seed bucket 2 to the seed bag supply position r. It is the composition to do. Therefore, the transfer speeds of the return device 3c and the lowering device 3d are set faster than the transfer speed of the transfer device 3a. By reducing the number of empty seed buckets 2, the cost can be reduced and the temperature of the hot water disinfection tank 1 is increased. Since the number of empty seed buckets 2 is small, the empty seed bucket 2 is less likely to get in the way when the operator visually recognizes the disinfection status and operation status in the hot water disinfection tank 1.

  In addition, the transfer of the seed bucket 2 that is intermittently transferred by the transfer device 3a is set so that the time in the transfer stop state is longer than the time during the transfer. Therefore, the seed bucket 2 can be retained for a long time above the hot water outlet 13 described later in the hot water disinfection tank 1, and the sterilizing effect of the seed can be enhanced. In addition, by increasing the transfer stop time of the transfer device 3a, the stop time of the ascending device 3b and the descending device 3d can be set longer so that the seed bucket 2 is stopped at the seed bag supply position r. The time can be set longer, and the seed (seed bag P) can be easily supplied to the seed bucket 2 that is stopped. The transfer stop time of the transfer device 3a can be changed by adjusting means, and the total time that the same seed bucket 2 is immersed in the hot water disinfection tank 1 can be changed by changing the transfer stop time. Therefore, the disinfection time of seeds can be changed according to the seed varieties (for example, soaked glutinous rice seeds are soaked for 10 minutes and soaked glutinous rice seeds for 6 minutes). Thereby, immersion time can be changed easily, without changing the transfer speed during transfer of the transfer apparatus 3a. The transfer device 3a, the lifting device 3b, the return device 3c, and the lowering device 3d are operated by a common drive source (motor).

  Further, when an emergency stop occurs due to a failure or inspection of the apparatus during seed disinfection work, control is performed to measure the emergency stop time and add it to the disinfection time. Therefore, the stop time of the intermittent transfer is shortened by the transfer device 3a by the amount of the emergency stop. At this time, if the set disinfection time is reached during an emergency stop, an alarm means such as a lamp warns. Therefore, seed damage such as seed cracking can be prevented by immersing the seed in hot water longer than necessary.

  At the bottom of the hot water disinfection tank 1, hot water jets 13 are arranged at predetermined intervals, and the hot water jet 13 is positioned below the stop position of the seed bucket 2 that is stopped while being intermittently transferred. The hot water is jetted out and the hot water passes through the hole of the seed bucket 2 and acts on the seed (seed pod) accommodated in the net-like seed bag P. In addition, the bottom part of the hot water disinfection tank 1 is configured to be inclined downward toward the intermediate part in the front-rear direction, and the drainage groove 14 is configured in the intermediate part.

  In the subsequent process of the hot water disinfection tank 1, a seed cooling device B is provided via a supply chute 15. The seed cooling device B is provided with a seed cooling tank 10 that is long in the front-rear direction on the rear side of the supply chute 15, and the seed cooling tank 10 is provided with a plurality of cooling buckets 8 from the front side toward the rear side. The cooling bucket 8 forms a large number of holes and is supported by a horizontal axis 8a so as to be rotatable in the horizontal axis. Then, when the cooling bucket 8 rotates and reverses about the shaft 8a, the seed bag P accommodated in the cooling bucket 8 is accommodated in the next cooling bucket 8. In addition, the cooling bucket 8 is rotated twice small when reversed, and the seed bag P is reliably discharged. In the cooling tank 10, as shown in FIG. 8, a partition wall 16 is provided for partitioning the inside of the tank for each accommodating portion of each cooling bucket 8, and this partition wall 16 is on the seed discharge side (discharge chute 17 side). The higher the one, the higher it is. The cooling water supply port 18 for supplying new water to the cooling tank 10 supplies water at the end of the seed discharge side (discharge chute 17 side) in the seed cooling tank 10. The cooling water from the water supply port 18 is sequentially supplied from the discharge side section partitioned by the partition wall 16 in the cooling tank 10.

  When the sensor detects that the seed bucket 2 has been lifted by the lifting device 3b and arrived just before being reversed by the reversing cam 7, the cooling bucket 8 closest to the hot water disinfection device A is reversed and then returned to its original state. The seed bucket 2 rises and is reversed by the reversing cam 7. Thus, immediately before the seed is supplied from the seed bucket 2 to the cooling bucket 8, the seed of the cooling bucket 8 can be supplied to the next cooling bucket 8, and the cooling time of the seed by the cooling bucket 8 can be extended. This can increase the cooling effect.

  The volume of the cooling bucket 8 is set larger than the volume of the seed bucket 2. Therefore, since the volume of the seed bucket 2 is small, it is possible to efficiently use hot water by reducing unnecessary portions in the hot water disinfection tank 1 where the seed bucket 2 is not supplied. Moreover, since the volume of the cooling bucket 8 is large, stirring of seeds is facilitated by air from an air outlet 19 described later, and the cooling effect is enhanced.

  Further, as shown in FIG. 2, an air ejection pipe 20 is provided below the cooling bucket 8 of the cooling tank 10, and air is supplied to the air ejection port 19 by a blower 21 toward the cooling bucket 8 being immersed. The air is blown out. Moreover, the hot water disinfection tank 1 is also provided with an air ejection pipe 19, and the air ejection pipe 19 is arranged so as to intersect (orthogonally) in a plan view above the hot water pipe 22 provided with the hot water ejection port 13. . Since the hot water pipe 22 extends in the longitudinal direction (front-rear direction) of the hot water disinfection tank 1 and the hot water outlet 13 ejects hot water to the left and right, convection in the short direction (left-right direction) of the hot water disinfection tank 1 It is generated uniformly over the whole area, and the temperature unevenness in the hot water disinfection tank 1 can be suppressed. The air ejection pipe 19 is located below the various child buckets 2 to be stopped, and all the seeds can be evenly stirred by ejecting air toward the various child buckets 2.

  The blower 21 is common to the cooling tank 10 and the hot water disinfection tank 1, and a long contact tube 23 is provided before and after contacting the air jet pipe 19 of the hot water disinfection tank 1 on the outer surface (side surface) of the hot water disinfection tank 1. Air is supplied through With this contact tube 23, the temperature of the air supplied to the hot water disinfection tank 1 can be raised, and the temperature drop in the hot water disinfection tank 1 is prevented.

  Further, an air ejection pipe 19 is provided at a position below the cooling bucket 8 in the cooling tank 10 and at a position below the seed bucket 2 in the hot water disinfection tank 1. When the air is ejected toward the bottom, as shown in FIG. 11, when the left and right recesses 8a and 2a are formed at the bottom of the cooling bucket 8 and the seed bucket 2, the left and right air ejection pipes 20 are fitted. The bottom surface of the seed bag P can be divided and expanded to efficiently supply air, and the permeation effect of hot or cold water can be enhanced.

Next, the seed disinfection process will be described.
A net-like seed bag P containing seeds is supplied to the seed bucket 2 stopped at the seed bag supply position r in the middle of the lowering device 3d. Then, the seed bucket 2 is lowered from the seed bag supply position r into the hot water disinfection tank 1 by the lowering device 3d and immersed in the hot water.

  In the hot water disinfection tank 1, the seed bucket 2 is transferred by the transfer device 3a, and the transfer device 3a is intermittently driven. The seed bucket 2 stops at a position facing the hot water jet 13 and is exposed to the hot water sprayed in the stopped state, thereby promoting the disinfection action of the seeds in the seed bag P.

  The seed bucket 2 transferred while stopping for a set time at each hot water outlet 13 is pulled up by the lifting device 3b on the transfer end side. Then, the seed bucket 2 is reversed by the reversing device 7 in the middle of the ascending device 3 b, the seed bag P in the seed bucket 2 is discharged, passes through the supply chute 15, and enters the cooling bucket 8 on the start end side of the cooling tank 10. Supplied.

  The emptied seed bucket 2 is subsequently transferred upward by the ascending device 3b, then intermittently transferred above the hot water disinfection tank 1 toward the transfer start end side by the returning device 3c, and again supplied by the descending device 3d to the seed bag. Circulated and transferred to position r.

The circulating transfer device 3 may be configured to continuously drive at a low speed instead of intermittent driving.
The seed bag P supplied to the cooling bucket 8 of the cooling tank 10 is cooled by cooling water. The cooling bucket 8 is configured to be interlocked with the intermittent drive of the circulation transfer device 3, and is rotated and reversed before the next seed bag P is supplied from the hot water disinfection tank 1 to the seed cooling tank 10, and the seed is transferred to the next cooling bucket 8. The bag P is supplied and the seed bag P from the hot water disinfection tank 1 is received. That is, the seed bag P is sequentially transferred to the next cooling bucket 8 by sequentially rotating and reversing from the cooling bucket 8 on the cooling end side, and the seed bag P from the hot water disinfection tank 1 is transferred to the cooling bucket 8 on the cooling start end side. I accept it.

And the seed bag P which passed the several cooling bucket 8 sequentially is discharged | emitted from the discharge chute 17, and is dried with the drying apparatus C of the next process.
According to this seed disinfection device, it is possible to efficiently disinfect hot water continuously while transferring a plurality of seed buckets 2 through a hot water disinfection tank 1 which is long before and after, and seeds are transferred from the hot water disinfection device A to the seed cooling device B. The bag P can be easily supplied.

  In addition, since the circulating transfer device 3 is intermittently driven every set time, the time for one seed bucket 2 to be immersed in hot water can be made constant, and since it is exposed to hot water at every stop, a large number of seed bags P And uniform disinfection can be performed efficiently. Since the cooling bucket 8 and the circulating transfer device 3 are driven in conjunction with each other, the time for immersing the seed bag P in the cooling water can be made constant, and a large number of seed bags P can be uniformly cooled. .

  In addition, by arranging the hot water spout 13 at every set interval over the entire hot water disinfection tank 1, temperature unevenness in the hot water disinfection tank 1 is prevented, and the seeds of the seed bag P in the seed bucket 2 penetrate the hot water. It can equalize and enhance the hot water sterilization effect. In addition, by intermittently transferring the seed bucket 2 in the hot water disinfection tank 1, seed immersion and water separation are quickened, the immersion sterilization time becomes accurate, and the sterilization effect can be enhanced. In other words, in the present embodiment, one seed bucket 2 is stopped and immersed above every 10 hot water jets 13.

Moreover, by jetting air into the cooling tank 10, the temperature rise of the cooling water in the cooling tank 10 can be prevented from being reduced, and the cooling effect can be increased.
Further, since the cooling bucket 8 is driven and reversed every predetermined time and the seed bag P is transferred while being cooled for a predetermined time in the cooling water, the cooling effect can be enhanced.
