Description

Technical Field

[0001] The invention relates to the technical field of seed treatment, and in particular to seed treatment equipment and a method for direct seeding of rice. Background Art

[0002] Rice direct seeding is a method of planting rice seeds directly in dry soil without the need for traditional seedling raising. Since direct seeding has high requirements for the growth conditions of rice seeds, especially when the soil moisture is insufficient, seed treatment technology has become one of the key factors to ensure the success of direct seeding rice cultivation. Therefore, seed treatment equipment for direct seeding rice can mix rice seeds with coating agents to form a coating layer, which can improve seed germination rate, enhance stress resistance, and improve resistance to diseases and pests.

[0003] The existing seed treatment equipment for direct seeding of rice is mostly used to mix the seeds and the agent to form a coating layer through a stirring rod when in use. However, the stirring range of the stirring rod used in the existing treatment equipment is limited, and some seeds or agents are easy to stick to the inner wall, which limits the coating and mixing efficiency. It takes a long time to stir to mix evenly, and the treatment efficiency is low. In addition, when the seeds and the agent are directly added to the equipment during treatment, it is easy to limit the subsequent mixing effect, and it is inconvenient to mix and treat evenly. At the same time, after the existing seed treatment equipment coats the agent on the seeds, in order to prevent the coating of the seeds from detaching or sticking, it is necessary to dry the seeds. During the treatment, the seeds need to be transferred to other equipment for drying, and the treatment efficiency is low. When wind drying, some positions cannot be blown by the wind, and it is necessary to dry while turning the plate, which has low treatment efficiency and is inconvenient to carry out uniform drying. Therefore, it is necessary to provide a seed treatment equipment and method for direct seeding of rice to meet the needs of users. Summary of the invention

[0016] S2: When the connecting pipe rotates, it drives the material distribution box to rotate, and the agent can be transported to the fixed pipe through the material delivery pipe. The agent flows into the connecting pipe through the through hole on the fixed pipe, and the agent is evenly distributed through the material distribution box on the connecting pipe. The multiple nozzles installed evenly spray the agent, and the agent can be sprayed while rotating to avoid adding the agent at one time, which affects the mixing effect;

[0017] S3: The processed seeds can be discharged into the processing box through the discharge pipe. When the connecting pipe rotates, it drives the air distribution box to rotate. The inclined surface of the second push block on the air distribution box pushes the first push block on the processing box, driving the processing box to move downward. At the same time, the processing box can squeeze the first spring through the slider. When the second push block moves over, it drives the processing box to move upward and shake under the push of the first spring, which can shake up the seeds and improve the drying uniformity.

[0018] S4: The dryer can filter impurities in the gas through the filter plate when conveying gas. When cleaning is needed later, the pull rods on the mounting boxes on both sides can be pulled. The pull rods drive the limit plate to move. Lifting the limit plate can squeeze the second spring, and the limit plate can drive the clamping rod to be removed from the connecting pipe and the cover plate. The cover plate is not hindered and the fixed shaft and the filter plate can be taken out for cleaning.

[0019] The working principle and beneficial effects of the present invention are:

[0020] 1. During stirring, the motor can be turned on to drive the first bevel gear to rotate, and the first bevel gear drives the connecting pipe to rotate through the second bevel gear. The multiple turning and mixing rods installed on the connecting pipe can stir the seeds, and the scraper on the connecting pipe can scrape the residue on the inner wall of the device shell. When the first bevel gear rotates, it can drive the fixed pipe to rotate through the third bevel gear, and the fixed pipe can drive the fifth bevel gear to rotate through the fourth bevel gear. The fifth bevel gear can drive the turning and mixing rod to rotate on its own. The turning and mixing rod rotates while rotating, so as to turn the seeds and improve the stirring effect.

[0021] 2. When the connecting pipe rotates, it drives the material distribution box to rotate as well. The agent can be transported to the fixed pipe through the feed pipe. The agent flows into the connecting pipe through the through hole on the fixed pipe. The agent is evenly distributed through the material distribution box on the connecting pipe. The multiple nozzles installed evenly spray the agent. The agent can be sprayed while rotating to avoid adding the agent at one time, which affects the mixing effect.

[0022] 3. The processed seeds can be discharged into the processing box through the discharge pipe. When the connecting pipe rotates, it drives the air distribution box to rotate. When the second push block on the air distribution box moves, the inclined surface of the second push block pushes the first push block on the processing box, driving the processing box to move downward. At the same time, the processing box can squeeze the first spring through the slider. When the second push block moves over, the processing box is not hindered. Under the push of the first spring, the processing box is driven to move upward and shake, which can shake up the distributed seeds. When the dryer conveys gas, it can be evenly sprayed through the air distribution box and the nozzle to dry the shaken seeds, thereby improving the drying uniformity.

[0023] 4. When the dryer is conveying gas, it can filter impurities in the gas through the filter plate. When cleaning is needed later, the pull rods on the installation boxes on both sides can be pulled. The pull rods drive the limit plate to move. Lifting the limit plate can squeeze the second spring, and the limit plate can drive the clamping rod to be taken out from the connecting pipe and the cover plate. The cover plate is not hindered and the fixed shaft and the filter plate can be taken out for cleaning. After the subsequent installation range, release the pull rod, and the limit plate and the clamping rod are reset under the push of the second spring.
