Description

[Detailed Description of the Invention] A. Purpose of the Invention A. Field of Industrial Application This invention is intended to provide a seed sterilizer suitable for disinfecting particulate seeds such as wheat.

B. Conventional techniques and their problems Conventional methods of disinfecting seeds involve manually sprinkling powder on the seeds, but this is time-consuming and difficult to reliably coat the surface of the seeds with powder.

B. Structure of the device A. Means for solving the problem In this case, the above-mentioned means are structured as follows.
Reference numeral 1 denotes a seed sterilizer, which is composed of a lower stirring section 2, an upper stirring section 8, and a fixed quantity feeder 15 for seeds. Therefore, the above-mentioned downward stirring section 2 has a box-like body 3 formed by side walls 3B, 3C connected to the front, rear, left and right sides of a bottom plate 3 having a rectangular plane, and two shafts 4, 5 in opposite directions. The shafts 4 and 5 are rotatably supported, and stirring claws 4A and 5A are protruded from the shafts 4 and 5, and a discharge port 6 for treated seeds is provided at the rear of the box-shaped body 3. A socket 7 to be connected to the upper stirring section 8 is provided on the front upper surface of the shaped body 3.
Further, the upper stirring section 8 rotatably supports a rotary tube 10 with its axis located within a seed drop tube 9 suspended at the axial center position of the socket 7, and the outer circumference of the rotary tube 10. Upper and lower scattering plates 10A and 10B each having a conical shape are protruded from the surface of the rotary cylinder 10.
A rotating shaft 11 with a spiral groove 11A carved on the outer periphery is inserted into the inside, and a disk 12 is fixed horizontally to the lower end of the shaft 11, and a scattering groove 12A is formed on the surface of the disk 12. At the same time, a chemical liquid inflow pipe 14 is communicated with the rotary cylinder 10 . In addition, the seed quantitative feeder 15 includes:
In a case 15A in which front and rear walls are provided at both ends of the horizontal pipe body, a seed inlet 15B is provided on the top surface of one side of the horizontal pipe body, and a seed outlet 15C is provided on the lower left surface of the case 15A. A shaft 15D is rotatably disposed at the center, and the shaft 15D is provided with a screw 15E and a stirring bar group 15F from the inlet side to the outlet side.

B Examples The details of each configuration will be explained below.

In the downward stirring section 2, a box-shaped body 3 is supported by support legs 3D having a predetermined height. Further, the stirring claws 4A, 5A are bent in a substantially rectangular shape on the side. Further, a chute 6A is connected to the discharge port 6. The socket 7 is configured in a funnel shape, and has a drop opening 7A that allows the treated seeds to fall into the box-shaped body, and bearings 7B and 7 that support the rotating cylinder 10 and shaft 11.
C is installed horizontally.

A quantitative seed feeder 15 is connected to the upper end of the seed drop tube 9 in the upper stirring section 8 via an obliquely installed connecting pipe 9A. Further, a guide wheel 9 for guiding seeds inward is provided at the lower end of the inner wall of the falling tube 9.
C is attached. Furthermore, the upper scattering plate 10
A is located inside the drop tube 9, and the lower scattering plate 10B is arranged so as to be located below the lower end of the drop tube 9. In the figure, 4' and 5' are extrusion screws attached to the base of the shaft.

The rotating shaft 11 has a spiral groove 11
It rotates in the twisting direction of A, and communicates with a disinfectant chamber 11B provided at the upper end of the shaft 11. This liquid chamber 11B and the disinfectant tank 13
and is connected by a pipe 14 having a fitting 14A.

The rotational direction of the rotating cylinder 10 and the shaft 11
The rotating direction of the shaft 11 is opposite to that of the shaft 11, and the rotating speed of the shaft 11 is configured to be about 10 times faster than the rotating speed of the rotating cylinder. Therefore, the configuration of the seed quantitative feeder 15 is as follows.
That is, the horizontal pipe body 1 having a predetermined diameter and length
5A' and front and rear walls 15A'' stretched across both ends of the horizontal pipe body, a seed inlet 15B is provided on the upper right surface of the horizontal pipe body, and a seed outlet 15C is provided on the lower left surface of the horizontal pipe body. It is being
15D is a shaft rotatably attached to the axis of the case, and a screw 15E and a stirring rod group 15 are attached to this shaft from the inlet side to the outlet side.
F is provided. The stirring rod group is composed of an appropriate number of stirring rods 15G installed radially around the shaft. In the figure, 1
5H is a hopper connected to the input port 15B, 15I
is the motor.

C Effect Explain along with the effects.

C. Effect of the invention Seeds to be sterilized are stored in the quantitative feeder, and a disinfectant is also stored in the disinfectant tank 13. Then, the seeds are dropped and the disinfectant solution is allowed to flow down. Seeds falling in the drop tube 9 are rotated by the rotating rotary tube 10 and the scattering plates 10A, 10B and try to scatter outward. On the other hand, the disinfectant liquid flows down along the spiral groove 11A, hits the disk 12, and is scattered around by the scattering groove 12A carved in the disk 12. This phenomenon ensures that the disinfectant solution adheres to the seeds. The thus treated seeds reach the downward stirring section 2, where they are further stirred and transferred toward the drop port 7A. Also in this part, the attachment of the disinfectant to the seeds can be made more reliable.

Here, the function and effect of the quantitative feeder will be explained. When particulate seeds to be sterilized or the like are put into the hopper, the seeds fall into the case 15A. The fallen seeds are sent to the exit side by screws and stirring rods. In this case, the screw acts to convey only the amount of seeds that have fallen into the case, and the stirring rod group consisting of single stirring rods planted at predetermined intervals transports the seeds sent from the screw. Send a fixed amount to outlet 15C. Since seeds can be sent in fixed quantities in this way, a disinfection process can be carried out more reliably after this process.
