Description

Technical Field

[0001] The present invention relates to the technical field of seed treatment, and specifically to an automatic rice seed turning and drying machine. Background Art

[0002] The drying of rice seeds is an important link to ensure seed quality. There are many drawbacks in the traditional manual turning and drying method. Not only is the labor intensity high and the efficiency low, but it is also difficult to accurately control the turning frequency and strength, which easily causes uneven drying of seeds, local overheating or moisture residue. In addition, manual operation cannot monitor the seed temperature in real time. In high-temperature weather, the internal structure of the seeds is easily damaged, resulting in a decrease in activity and affecting the subsequent planting effect. Although the existing rice seed turning and drying machinery and equipment have achieved a certain degree of automation, there are still obvious deficiencies. Most equipment lacks environmental perception and intelligent regulation functions and cannot automatically take protective measures during high-temperature periods. If the seeds are exposed to the sun for a long time without timely sunshading and cooling, they are likely to lose their vitality. At the same time, the turning and drying methods of existing equipment are mostly one-way turning or local stirring, making it difficult to achieve all-round and alternating turning of seeds, resulting in insufficient contact between seeds and air, low moisture evaporation efficiency, extended drying cycles, and increased production costs. With the development of rice planting towards large-scale and intelligent directions, the traditional drying method and existing equipment can no longer meet the needs of modern agricultural production. Therefore, it is urgent to develop an automated equipment with intelligent temperature control and efficient turning and drying functions. This equipment needs to achieve real-time monitoring of seed temperature, automatically start the sunshade net when the temperature is too high, and at the same time achieve all-round drying of seeds through alternating turning, so as to improve the drying efficiency and quality, provide technical support for the standardized production of rice seeds, and contribute to the development of agricultural modernization.

[0003] After retrieval, it is found that the prior art with the publication number of CN119713783A discloses an automatic rice seed turning and drying machine, including a box body. A turning scraper is slidably and conformally arranged on the bottom surface of the box body. The turning scraper includes a plurality of scraping rods spaced perpendicular to a cross bar. The cross bar is fixed to the bottom of a moving vertical rod. The moving vertical rod is slidably connected to a first lead screw. The moving vertical rod also penetrates through a first supporting cross plate. A first bevel gear is coaxially fixed to one end of the first lead screw. The first bevel gear is externally meshed with a second bevel gear in a first driving mechanism that intermittently rotates reciprocally with a driving bevel gear. This invention has the following advantages and effects: continuously turning the materials in the box body, improving the scraping effect, and being fully automatic, significantly reducing the operation intensity of workers, saving time and effort.

[0004] Therefore, based on the above retrieval and combined with the existing ones, when the above solution is used, the scraping plate can contact and scrape all the seeds in the box, continuously turning the seeds in the box. However, when the temperature of the seeds being dried is too high, it will cause damage to the germ of the seeds, and the above patent cannot cool the seeds, which has limitations. For this reason, we propose an automatic turning and drying machine for rice seeds. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the electromagnet disk touches the ground, the pressure sensor is triggered to cut off the power supply. The gravity iron block loses magnetic attraction and falls to the ground. At this time, the moving box and the sunning box continue to move. The stationary gravity iron block will pull the sunshade net to unfold and cover the just-discharged rice seeds, automatically achieving sunshade and temperature reduction, avoiding damage to the seeds due to excessive exposure to the sun, effectively ensuring the seed quality. At the same time, this process does not require manual operation, improving the automation degree and efficiency of the sunning operation and reducing the labor cost. 2. During the sunning process of rice seeds, the rice seeds are neatly discharged from the sunning box and flipped to another row, forming regular alternating flips, ensuring that each seed can fully contact with the air, greatly improving the uniformity of seed exposure. At the same time, under the continuous movement of the moving box and the sunning box, the seeds continuously cycle into the sunning box, are discharged, and flipped, forming an efficient and continuous sunning process. Compared with the traditional sunning method, the overall sunning time is significantly shortened, and the operation efficiency is remarkably improved. Description of the Drawings

The second push plate 62 and the top end of the inner wall of the water tank 22 are fixedly connected through a fourth elastic telescopic rod 61. At this time, the fourth elastic telescopic rod 61 is in a compressed state. When the rotating arm 18 rotates downward, the rotating arm 18 will drive the outer wall of one of the electromagnet discs 36 to abut against the ground. At this time, the rotating arm 18 will also drive the outer connecting pipe 43 to rotate, and the outer connecting pipe 43 drives the first through port to communicate with the second through port. At this time, the second push plate 62 will push the liquid water inside the water tank 22 into the fixed pipe bracket 37 and then discharge it from the nozzle 38, so that the liquid water will be sprayed on the outer wall of the adjacent sunshade net 32. In this way, when the sunshade net 32 is laid above the rice seeds, the cooling speed of the rice seeds can be accelerated.

[0022] The working principle of the present invention is as follows: When in use, the tractor 1 is started. The tractor 1 will push through the second rotating column 63 and the matching column 60. At this time, the connecting frame 2 limits the clamping plate 13 through the clamping column 16, so that the overall structure can move forward. When the moving box 3 moves, the piled-up rice seeds will push open a corresponding rotating plate 8. At this time, the rice seeds will accumulate inside the moving box 3, and the other rotating plate 8 is pushed. At this time, the outer wall of this rotating plate 8 will abut against the outer wall of the limiting block 6, and the limiting block 6 will limit the rotating plate 8. On the contrary, when the moving box 3 moves in the opposite direction, according to the above, one of the two rotating plates 8 is pushed open and the other is closed. Then, the servo motor 12 is started. The servo motor 12 drives the two transmission gears 11 to rotate. The two transmission gears 11 drive the first rotating column 20 to rotate at a high speed. The two first rotating columns 20 rotate in opposite directions. The rice seeds will enter the sun-drying box 4 through the through pipe 24 under the push of the two first rotating columns 20. At this time, the sun-drying box 4 is also moving. The rice seeds accumulate inside the sun-drying box 4. At this time, the rice seeds inside the sun-drying box 4 are in a static state relative to the sun-drying box 4. The rice seeds will pass through the discharge opening 5 and be discharged from the inside of the sun-drying box 4. Moreover, under the action of the discharge opening 5, the rice seeds will become neat, so that the rice seeds will flip from one row to another row, making the flipping of the rice seeds more comprehensive. When the sun-drying box 4 and the discharge opening 5 move, the universal wheels 10 will reduce the friction between the sun-drying box 4 and the moving box 3 on the ground; When the rice seeds pass through the inside of the through pipe 24, the rice seeds will abut against and rub against the outer wall of the first elastic telescopic rod 28. At this time, the rice seeds will transfer the temperature to the ethanol inside the first elastic telescopic rod 28 through heat conduction. The expansion of the ethanol will drive the first elastic telescopic rod 28 to extend. When the first elastic telescopic rod 28 extends, it will pull the first pull rope 27. The first pull rope 27 will drive the abutting block 30 to slide downward in the inner sleeve 25. The downward movement of the abutting block 30 will push all the blocking balls 29. When the blocking balls 29 are separated from the inner wall of the first inner connecting pipe 26, at this time, the compressed gas inside the rubber corrugated sleeve 17 will enter the inner sleeve 25 through the outer sleeve 21. The high-pressure gas inside the inner sleeve 25 will enter the second elastic telescopic rod 39. The extension of the second elastic telescopic rod 39 will pull the second pull rope 44. The second pull rope 44 will drive the moving rod 50 to move. The moving rod 50 will drive the curved arm 52 to move. The curved arm 52 will abut against and rotate with the outer wall of the rotating block 54. It should be noted that when the second elastic telescopic rod 39 extends, it will also pull the third pull rope 46. The third pull rope 46 will drive the recovery wheel 47 and the rotating arm 18 to rotate. The rotating arm 18 will drive a corresponding electromagnet disk 36 to abut against the ground; When the outer wall of the corresponding electromagnet disk 36 abuts against the ground, the pressure sensor on the outer wall of the corresponding electromagnet disk 36 will be triggered, causing the corresponding electromagnet disk 36 and the electromagnet column 35 to be powered off. At this time, the gravity iron block 33 will lose the magnetic attraction of the electromagnet disk 36, and the gravity iron block 33 will fall to the ground. The moving box 3 and the sunning box 4 are still moving. At this time, the gravity iron block 33 is in a static state relative to the sunning box 4, and the sunscreen net 32 will be pulled and unfolded to cover the upper end of the rice seeds discharged from the inside of the sunning box 4, shading and cooling the rice seeds; When the gravity iron bar 45 on the outer wall of the corresponding sunscreen net 32 falls, at this time, the moving box 3 can only sun and cover a row of rice seeds. When the corresponding row of rice seeds is recovered outside the wall, the tractor 1 is lifted upward at this time. The tractor 1 will drive the connecting frame 2 to rotate upward. Note that the overall weight of the tractor 1 is only sixty kilograms. When the tractor 1 is lifted, it takes the second rotating column 63 as the fulcrum, so the lifted weight is lighter. The connecting frame 2 will drive the rubber corrugated sleeve 17 and the clamping column 16 to move upward. When the clamping column 16 disengages from the inner wall of the corresponding clamping hole 14, it drives the tractor 1, the connecting frame 2 and the second rotating column 63 to rotate together. When the rubber corrugated sleeve 17 disengages from the abutment against the outer wall of the clamping plate 13, the rubber corrugated sleeve 17 will suck the previous air. At this time, according to the above, when the second elastic telescopic rod 39 contracts, the second elastic telescopic rod 39 will also release the third pull rope 46. The rotating arm 18 will reset and rotate, and the recovery wheel 47 will recover the third pull rope 46. The gas inside the second elastic telescopic rod 39 will return to the inside of the rubber corrugated sleeve 17; When the second elastic telescopic rod 39 contracts, it will also pull the moving column 41. The moving column 41 will release the second pulling rope 44. At this time, the second elastic spring 49 will drive the moving rod 50 to reset. The moving rod 50 drives the bent arc arm 52 to abut against the outer wall of a nearby abutting bent arc block 53. The abutting bent arc block 53 is used to push the rotating block 54. The rotating block 54 drives the fixed pipe rack 37 to rotate, so that another electromagnet disk 36 will move to the position of the previous electromagnet disk 36. At this time, the pulling tractor 1 is pulled. The pulling tractor 1 will drive the moving box 3 and the sun-drying box 4 to move, so that the moving box 3 and the sun-drying box 4 are translated to the same horizontal plane as the new rice seeds. Then the pulling tractor 1 is lifted upward. According to the above working principle, the pulling tractor 1 will drive the clamping column 16 to insert into another clamping hole 14 through the connecting frame 2, and the rubber corrugated sleeve 17 will be compressed again. Note that when the pulling tractor 1 drives the connecting frame 2 to rotate, it will also drive the corresponding pulley 9 to rotate. The pulley 9 will drive another pulley 9 to rotate through the transmission belt 19. Another pulley 9 will drive the rotating arm 18 to rotate 180 degrees. At this time, the rotating arm 18 will drive the corresponding electromagnet disk 36 to abut against the ground, and continue to release the sunshade net 32 and the gravity iron block 33, and continue to perform sun-drying and covering. When the fixed pipe rack 37 rotates, it will also drive the matching disk 55 to rotate. The matching disk 55 drives all the third elastic telescopic rods 56 and the matching balls 57 to rotate. The matching balls 57 will disengage from the inner abutment of the corresponding matching holes 58. When the fixed pipe rack 37 is stationary, it has a limiting effect. And when the sunshade net 32 on the outer wall of the corresponding iron sleeve 34 is completely released, a new iron sleeve 34 can be sleeved on the outer wall of the electromagnet column 35. The outer wall of the new iron sleeve 34 has a complete sunshade net 32, and the old iron sleeve 34 is taken out; When it is necessary to recycle the sunshade net 32, at this time, the pressure sensor needs to be turned off, so that the electromagnet disk 36 and the electromagnet column 35 are always in an energized state. The gravity iron bar 45 is magnetically abutted against the outer wall of the iron sleeve 34. The electromagnet disk 36 abuts against the ground and drives the electromagnet column 35 to rotate, and the electromagnet column 35, the iron sleeve 34 and the gravity iron bar 45 will be rotationally recycled, which is fast and convenient.
