Description

[Detailed description of the invention] The present invention is a coating machine for seeds, specifically a coating machine for coating the surface of seeds to promote germination and prevent floating seedlings, which is applied to the flooded direct sowing cultivation method. Regarding.

Conventionally, in the flooded direct sowing cultivation method, in order to solve problems such as poor germination of buried seeds and floating seedlings,
The surface of seeds is coated with a powder containing calcium peroxide as an active ingredient, but conventional coating machines, as shown in Figure 2, freely rotate a circular container B on a stand A. It is supported by a motor and driven by a motor.
A water sprayer D supported on a support stand C is attached, and the container B is filled with seeds, and the container B is filled with seeds.
The coating powder is added while rotating the container B, and water is sprayed from the sprayer D to make the powder adhere to the seeds, and after coating is completed, the rotation of the container B is stopped and the powder is coated. The seeds are removed and dried in the shade.

However, according to the coating machine configured as above, since it is a batch type, it becomes large in size if the processing capacity is to be improved, and the consumption capacity increases because the container D is rotated, and the seed coating machine by the sprayer D is There was a problem in that the water could not be sprayed uniformly on the seeds, and as a result, the powder agent formed into lumps, making it difficult to uniformly coat all the seeds.

The purpose of this invention is to use a rotating body with a spiral flow path to perform continuous coating work, to obtain sufficient processing capacity despite its small size, and to easily achieve uniform coating. This is how it was done.

The structure of the present invention is that a hopper for seeds and a hopper for coating material are provided in the upper part, and a metering device is provided in the lower part of these hoppers. By arranging the rotating body to freely rotate and providing an outlet at the lower end of the flow passage at the bottom of the rotating body, each hopper can be filled with seeds and coating material continuously and uniformly. It is designed so that coating can be applied to the surface.

Next, an embodiment of the coating machine of the present invention will be described based on FIG.

In the drawing, a cylindrical casing 2 is supported on a base 1 that supports wheels 1a and 1b at the bottom, and a seed hopper 3 and a coating material hopper 4 are supported on the top of the casing 2. hand,
At the bottom of each of these hoppers 3, 4, quantitative feeding devices 5, 6 consisting of feeding rolls are provided, and each of these feeding devices 5, 6 is driven by a first motor _M1 fixed to the casing 2. A cylindrical rotating body 7 having a continuous spiral flow passage 70 is arranged below the feeding devices 5 and 6, and a rolling body 8 such as a roller is mounted on a support 8 fixed to the base 1.
a, and the rotating body 7 is driven by a second motor _M2 fixed to the base 1, and at the lower part of the rotating body 7, the lower end of the flow passage 70 The casing 2 is provided with an annular chute 10 surrounding the outlet 7a, and a coated seed tank 11 for receiving coated seeds is provided below the chute 10, and the casing 2 is further provided with an annular chute 10 surrounding the outlet 7a, and a coated seed tank 11 for receiving coated seeds. Rotating body 7
A plurality of nozzles 12 facing the downstream passage 70 in...
This supports a spray pipe 13 having a diameter.

More specifically, the rotating body 7 has a body 71 thereof.
has a cylindrical shape with a bottom, and a cross section L is formed inside the body 71.
The belt-like member 72 is arranged in a donut shape and spirally, and the belt-like member 72 is fixed to the inner wall of the body 71 to form the flow passage 70. The pitch is such that the seeds and coating material fed out from the feeding devices 5 and 6 can flow down while rolling due to the rotation of the rotating body 7, and the length is such that the coating material can be reliably applied to the seeds flowing out from the outlet 7a. The length should be such that it can be attached.

The belt-shaped member 72 for forming the downstream passage 70 is attached to the body 71 of the rotating body 7 so as to be horizontal in the cross section as shown in FIG.
The belt-shaped member 7 is fixed to a doughnut-shaped member.
The outer circumferential side of No. 2 may be fixed so as to be inclined upwardly with respect to the inner circumferential side. By doing so, the seeds can be rolled more effectively.

Further, in the embodiment shown in FIG. 1, an electric heater 14 is disposed below the bottom surface of the rotating body 7, and
4 heats the air below the bottom surface and causes the heated air to flow in the direction of the arrow so that the seeds that reach the vicinity of the outlet 7a can be dried by the heated air.

By doing so, seeds can be sown immediately without drying in the shade, and at the time of sowing, of course, the powder-coated seeds stored in the powder-coated seed tank 11 from the chute 10 are bonded to each other in the tank 11. Since the bridging phenomenon can be prevented, and the heated air can be circulated through the center of the downstream passage 70, coating can be done quickly and efficiency can be improved.

In FIG. 1, 21 is an air intake port provided at the lower part of the casing 2, and 22 is an exhaust hole. Further, 23 is a viewing window provided at an intermediate portion of the casing 2.

Next, a case will be described in which seeds are coated using the coating machine configured as described above.

For coating, first, the seed hopper 3 is filled with soaked and consumed seeds, and the coating material hopper 4 is filled with a powder coating material containing calcium peroxide as an active ingredient, and then This is done by driving each of the motors M ₁ and M ₂ , and the first motor M ₁
By driving the respective feeding devices 5 and 6, the seeds and the coating material are fed out at a constant ratio and supplied to the downstream passage 70 of the rotating body 7.

The seeds and coating material supplied to the downstream passage 70 flow downward while being agitated by the driving rotation of the rotating body 7, and during this stirring, water is sprayed from the nozzle 12. Since this spraying is performed in the downstream passage 70 flowing down while stirring, it can be applied evenly to all the seeds flowing down, and the coating material adheres to the seeds by the water spraying. This allows the coating material to adhere uniformly to the seeds.

The seeds thus coated with the coating material are dried with air heated by the heater 14 and taken out from the outlet 7a via the chute 10 to the coated seed tank 11.

As described above, since the coating of the seeds is carried out during the process of flowing down the flow passage 70, continuous work is possible, the overall size can be reduced relative to the processing capacity, and water spray is also carried out in the flow down the flow path 70. Since it can be done in the process, it is possible to spray the seeds evenly, making it possible to coat them uniformly.

In the embodiment described above, the flow passage 70 is formed using a belt-shaped member having an L-shaped cross section, but a gutter-like member may also be used, and feeding rolls may be used as the quantitative feeding devices 5 and 6. , or any other structure that can be fed out at a constant rate, it is not limited to a feeding roll.

As described above, the present invention has a hopper 3 for seeds and a hopper 4 for coating material in the upper part, fixed quantity feeding devices 5 and 6 in the lower part of these hoppers 3 and 4, and a spiral hopper below these feeding devices 5 and 6. The present invention is characterized in that a cylindrical rotary body 7 having a downstream passage 70 of the shape is arranged freely to rotate, and an outlet 7a is provided at the lower end of the downstream passage 70 at the bottom of the rotary body 7. , a continuous coating operation can be performed, and sufficient processing capacity can be obtained despite the small size.Moreover, when spraying water, it can be done in one process of flowing down the flow passage 70, so that the seeds can be sprayed evenly. This makes it possible to spray and achieve a uniform coating without any spots.
