[0037] Example 2: Reference Figure 2-Figure 9 :This embodiment provides a corn seed coating method based on embodiment 1, which is applicable to the above-mentioned corn seed coating machine and comprises the following steps: Step 1: The weight of the corn is input through the controller, and the controller starts the push rod motor 21 according to the weight of the corn to drive the mounting frame 22, the medicine barrel 23 and the adjustment block 217 to move, adjust and change the space in the medicine barrel 23, control the amount of medicine according to the weight of the corn, and then add medicine into the medicine barrel 23; Step 2: Start the push rod motor 21 to push the medicine barrel 23 downward. When the gear 3 210 and the rack 2 218 are about to be disengaged, the adjusting block 217 pulls out the medicine barrel 23, and the bottom of the medicine barrel 23 opens. The medicine inside falls on the receiving tray 216 along the adjusting block 217, and then leaks out from the discharge port opened on one side of the receiving tray 216 onto the corn below; Step 3: Start the motor 51 to drive the gear 1 52 to rotate forward, the gear 1 52 drives the one-way gear 2 44 and the rotating shaft 3 43 to rotate, the rotating shaft 3 43 rotates to drive the spiral stirring rod 41 to rotate so that the corn rotates and mixes with the medicine; Step 4: After mixing for a specified time, the heater 42 is started to dry the coated corn kernels; Step 5: After the corn in the middle position is dried for a specified time, the motor 51 is started to drive the gear 1 52 to reverse, so that the reciprocating screw 33 rotates to drive the movable frame 32 and the outer ring 31 to move upward. When the outer ring 31 moves upward, the scraper ring 38 scrapes the agent on the inner wall of the outer ring 31 onto the corn, and then resets. Then the motor 51 drives the gear 1 52 to rotate forward and controls the speed to mix the corn. The dried corn will mix the scraped agent again, and then continue to dry. When it is completely dry, pull the pull plate 18 to separate the magnet 19, pull the baffle 17 away to open the discharge port 15, so that the coated corn leaks out from the discharge chute 16, and the coating is completed.

[0038] Working principle: The weight of the corn is input through the controller, and the controller starts the push rod motor 21 according to the weight of the corn, driving the mounting frame 22, the medicine barrel 23 and the adjusting block 217 to move up or down. Moving up increases the length of the adjusting block 217 inserted into the medicine barrel 23, and moving down reduces the length of the adjusting block 217 inserted into the medicine barrel 23 or even pulls out the medicine barrel 23. The length of the adjusting block 217 in the medicine barrel 23 can change the space in the medicine barrel 23, thereby controlling the amount of medicine added, and adding a prescribed amount of medicine according to the weight of the corn. When moving upward, the push rod motor 21 pulls the mounting frame 22 to drive the rotating shaft 1, gear 24, limit block 25, medicine barrel 23, structural box 28, rotating shaft 29, gear three 210, bevel gear 1 211, screw 212, guide rod 214, bevel gear 213, movable plate 215, receiving tray 216 and adjusting block 217 to move upward synchronously, and the gear three 210 moves up. When the adjusting block 217 is inserted into the medicine barrel 23, the space inside the medicine barrel 23 becomes smaller, and the amount of medicine poured in will be controlled. When the adjusting block 217 moves downward, the adjusting block 217 gradually pulls out the medicine barrel 23. The more it is pulled out, the larger the space inside the medicine barrel 23 becomes, and the more medicine is loaded. When the gear 3 210 and the rack 2 218 are about to be disengaged, the adjusting block 217 pulls out the medicine barrel 23, and the bottom of the medicine barrel 23 is opened. The medicine inside falls on the receiving tray 216 along the adjusting block 217, and then leaks out from the discharge port opened on one side of the receiving tray 216 to the corn below. If it is necessary to control the adjusting block 217 to move up and down during mixing, the bottom of the medicine barrel 23 is opened at a fixed point or at a fixed time, so as to realize fixed-point and timed feeding; When the medicine in the medicine barrel 23 is used up, the push rod motor 21 continues to drive the mounting frame 22 to drive the rotating shaft 1, gear 24, limit block 25, medicine barrel 23, structural box 28, rotating shaft 29, gear 3 210, bevel gear 1 211, screw 212, guide rod 214, bevel gear 213, movable plate 215, receiving plate 216 and adjusting block 217 to move up synchronously, and gear 3 210 is meshed with rack 218 when moving up, and gear 3 210 drives rotating shaft 29, bevel gear 1 211, bevel gear 213 and screw 212 to move down, and the limit block 25 is disengaged from the limit column 26, and then gear 24 is meshed with rack 1 27, and gear 24 rotates to drive rotating shaft 1 and medicine barrel 2 3 rotation, when the gear 24 and the rack 1 27 are disengaged, the medicine barrel 23 is in a horizontal state, and the structure box 28 and other structures are flipped accordingly. After flipping, the structure box 28 is limited by the mounting frame 22, and the medicine barrel 23 cannot continue to rotate. It continues to move downward so that the medicine barrel 23 is inserted into the corn in the stirring process. The stirring rotation direction of the corn is opposite to the direction of the medicine barrel 23. The rotating corn will pass through the medicine barrel 23 and contact the adjustment block 217 and the receiving plate 216 to take away the residual medicine. In order to ensure the stability of the medicine barrel 23, the connection between the rotating shaft 1 and the mounting frame 22 has strong friction. In addition, the mounting frame 22 limits the structure box 28, so that the medicine barrel 23 and other structures can be correctly moved up and reset; When stirring and mixing is required, the motor 51 drives the gear 1 52 to rotate forward, which satisfies the one-way gear 2 44 to drive the shaft 3 43 to rotate. The shaft 3 43 rotates to drive the spiral stirring rod 41 to rotate and drive the corn to rotate to mix the medicine. When the corn rotates, the medicine will be thrown on the inner wall of the outer ring 31 due to centrifugal force. When a certain degree of mixing is achieved, the heater 42 is started. The heater 42 dries the coated corn kernels, and the heat diffuses from the middle to the outside. When the corn in the middle position is dried to a certain degree, the motor 51 is started to drive the gear 1 52 to reverse, so that the reciprocating screw 3 3 rotates to drive the moving frame 32 and the outer ring 31 to move upward. When the outer ring 31 moves upward, the scraper ring 38 scrapes the medicine on the inner wall of the outer ring 31 onto the corn, and then resets. Then the motor 51 drives the gear 1 52 to rotate forward and controls the speed to mix the corn. The dry corn mixes the scraped medicine again. The dry coating is also more likely to stick to the medicine on the surface to avoid residual and waste of the medicine. After complete drying, the pull plate 18 is pulled apart from the magnet 19, and the baffle 17 is pulled away to open the discharge port 15, so that the coated corn leaks out from the discharge chute 16 to complete the coating.
