Description

[Detailed explanation of the invention] (a) Industrial application field The present invention is a seed that enables seeds to be directly sown with a submerged direct sowing machine to be coated easily, uniformly, and automatically with a powdered chemical such as an oxygen supply agent. The present invention relates to a drug coating machine.

(b) Prior art This type of chemical coating machine for seeds, which has been commonly used in the past, has a rotating coating pan installed diagonally with respect to a pedestal, and an oxygen supply agent and water are alternately and gradually introduced into the machine. This process was repeated while checking the coating condition of the seeds to ensure the desired amount of coating was applied, requiring a person to be present for about 30 minutes each time.

(c) Problems that the invention aims to solve By the way, it is quite difficult to uniformly coat each seed with an oxygen supply agent without causing the seeds to stick to each other. Therefore, the worker has to be present, but if a large amount of coating is to be done, even if it is only once or twice, it becomes a considerable mental and physical burden on the worker. was.

(d) Means for solving the problem Therefore, in the present invention, a coating pan 1 is attached to a drive shaft, and a drug supply device 8 provided with a water spray device 5 and a drug detection sensor 9 is disposed above the coating pan 1. A control mechanism 10 is provided, which includes a water supply timer 16 and a medicine supply timer 17 that can set the supply time of one stroke of the water spray device 5 and the medicine supply device 8 to any time, and a main switch 13. Water supply timer 16
And the medicine supply timer 17 is connected to the water spray device 5.
and the drug supply device 8, and the drug detection sensor 9 is connected to the drug supply device 8 so that the drug detection sensor 9 turns off the main switch 13 when the drug supply is finished.
and the main switch 13 are connected.

(E) Example Next, an example of the seed chemical coating machine according to the present invention will be described based on FIGS. 1 and 2.

1 is a coating pan disposed diagonally on a pedestal 2, and this coating pan 1 is connected to a motor 3.
It is attached to the drive shaft of the motor and is structured to rotate in the direction of the arrow in the drawing. 5 is a water spray device disposed above the coating pan 1. The water spray device 5
has a water tank 4 and a flexible nozzle 6. Further, on the side of the water spray device 5, a drug supply device 8 equipped with a dispensing device 7 at the bottom thereof is arranged. Reference numeral 9 denotes an electrostatic drug detection sensor disposed above the dispensing device 7 of the drug supply device 8 to detect the presence or absence of a drug in the drug supply device 8 .

10 is the water spray device 5 and the drug supply device 8
This is a control mechanism for controlling the operations of The water spray device 5, drug supply device 8, and control mechanism 10 are supported and fixed to a support frame 11. On the operation panel 12 of the control mechanism 10, 13 is a main switch for turning the power on and off;
Reference numerals 14 and 15 indicate starting switches. When the starting switch A14 is pressed, the coating pan 1 starts rotating, and when the starting switch B15 is pressed, the water spray device 5 and the drug supply device 7 become operational, and either water or the drug is supplied. can be supplied toward the coating pan 1 with a certain time difference. Reference numeral 16 denotes a water supply timer which, when connected to the water spray device 5, can set the water supply time for one stroke of water sprayed from the nozzle 6 of the water spray device 5. and 17
is a drug supply timer, and by connecting it to the drug supply device 8, it is possible to set the supply time for one stroke of the drug supplied from the delivery device 7 of the drug supply device 8. Further, the drug detection sensor 9 is connected to the main switch 13 so that the main switch 13 is turned off when the drug supply device 8 detects that there is no drug left. The water supply timer 16 and the medicine supply timer 17 can be set in seconds, and can be set up to 20 divisions, where one division is 1 second, that is, up to 20 seconds at the maximum.

(F) Effect When coating the seeds with the drug, first place the required amount of seeds in the coating pan 1 (the required amount of seeds here is proportional to the area of the field where the seeds are to be sown). Usually, it is possible to coat about 5 times in one coating.It goes without saying that this value varies depending on the capacity of the coating pan.)
Next, the water supply tank 4 and drug supply device 8 of the water spray device 5 are filled with water and drugs in amounts commensurate with the amount of seeds previously put into the coating pan 1, respectively.
(Since the amount of water and medicine required for a certain amount of seeds are almost constant, the prescribed amounts can be set in advance.) Next, the water supply timer 16 and the medicine supply timer By setting 17 arbitrarily, the water supply time and medicine supply time for one stroke are set. The setting time varies depending on the condition of the seeds prepared for coating, but a range of 5 to 10 seconds is usually appropriate. Next, when the main switch is turned on, the control mechanism 10 becomes operational. Next, when the start switch A14 is pressed, the coating pan 1 starts rotating. Next, when the start switch B15 is pressed, the water spray device 5 is activated, and water is sprayed from the nozzle 6 toward the seeds for the time previously set by the water supply timer 16. At the same time as the water supply ends, the delivery device 7 of the chemical spraying device 8 is activated, and the chemical is supplied to the seeds for the time previously set by the chemical supply timer 17.

After one stroke of water and medicine has been supplied in this way, the coating pan 1 continues to rotate for several minutes to ensure that the medicine adheres to the seeds. From the second step, water supply and medicine supply are performed alternately in the manner described above, and this repetition is continued for the nth step. Then, when the drug detection sensor 9 in the drug spray device 8 detects that there is no drug in the drug spray device 8 in the n-th step, water is supplied for the time set by the water supply timer 16, and then The operation of the water spray device 5 and the delivery device 7 is stopped, and after the coating pan 1 continues to rotate for several minutes, the main switch is automatically turned off and stopped. timer 1
6, 17, main switch 13, start switch 1
The automatic operation of each device after operating 4 and 15 is programmed in the control mechanism 10, and if left alone, the seeds put into the coating pan 1 will be coated with the chemical in an ideal state. be.

(g) Effects of the invention Since the invention is constructed as described above, it does not require any special skills and can be easily carried out by any number of people, and there is no need for a person to be present during the coating work, and it is easy to use other people. This has the effect of allowing you to coat while working.
