Description

Technical Field

[0001] The invention relates to the technical field of seed drying, and in particular to a seed drying machine for agricultural production. Background Art

[0002] Generally, newly harvested seeds have a high moisture content. If appropriate measures are not taken to deal with them, the high moisture content seeds will have a high respiration intensity during long-term storage, which will release a lot of heat, making it easy for the seeds to mold, or be poisoned by alcohol produced by lack of oxygen respiration, or die from freezing at low temperatures. Therefore, seed companies usually place seeds in dryers and use wind to dry them.

[0003] For example, a patent application document with Chinese invention publication number CN113432407A discloses a novel rice seed dryer, which places rice seeds on a conveyor and spreads them flat, then introduces the heat into a drying pool through an exhaust pipe, and then dries the rice seeds on the conveyor with the hot air, while high-temperature steam is discharged from the top of the drying pool.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. In the present application, a hollow rotating rod, spiral blades, stirring blades and bristles are arranged. When the spiral blades stir and transport the seeds, the seeds will push the stirring blades to rotate to stir the seeds. At the same time, the bristles on the stirring blades can effectively remove excess grease on the surface of the seeds, thereby playing a cleaning role, and the bristles can cover a larger surface area of ​​the seeds, making the stirring process more uniform and comprehensive, which helps to ensure that each seed can be fully stirred, thereby improving the overall drying effect of the seeds. At the same time, the first magnet on the stirring blade will be attracted by the fourth magnet on the hollow rotating rod during the rotation process. This attraction will increase the rotation speed of the blades, thereby lifting the seeds during the seed stirring process and forming a certain parabolic path in the air, thereby achieving mixing and uniform distribution of the seeds. This lifting effect helps to break the agglomeration state of the seeds caused by the precipitation of grease, thereby improving the drying effect.

[0020] 2. In the present application, by setting the oil guide groove, ball bearings and grooves, when the seeds are transported and stirred by the spiral fan blades, the ball bearings will exert a thrust on the seeds during the rotation process, causing them to roll or throw up, thereby achieving uniform mixing of the seeds and helping to break up the agglomeration of the seeds. At the same time, the grease on the seeds can also reduce the friction resistance during the rotation of the ball bearings, making the rotation of the ball bearings smoother, which not only improves the stirring efficiency, but also reduces the wear and energy consumption of the equipment. When the seeds roll on the ball bearings, the grease will flow along the grooves and eventually flow into the oil guide grooves on the spiral fan blades for subsequent collection, avoiding the accumulation of grease on the spiral fan blades and seeds. This not only helps to keep the equipment clean, but also improves the utilization rate of the grease.

[0021] 3. In the present application, by setting up a hot air blower and a spiral air outlet duct, while the spiral fan blades drive the seeds to rotate, the hot air ejected through the spiral air outlet duct will combine with the airflow generated by the rotation of the spiral fan blades to form a uniform hot air to dry the seeds in all directions. Moreover, since the seeds are close to the spiral air outlet duct, the hot air ejected through the spiral air outlet duct can act well on the seeds, increase the movement speed and mixing uniformity of the seeds. This design makes the stirring and drying process more efficient and can achieve an ideal stirring effect in a short time.

[0022] 4. In the present application, the third motor, the first gear, the first transmission rod, the second magnet and the third magnet are arranged to drive the trapezoidal scraper to rotate on the outer wall of the mounting shell and the inner wall of the outer shell, so that the seeds on the outer wall of the mounting shell and the inner wall of the outer shell are effectively scraped off and concentrated at the bottom of the inner shell. When the trapezoidal scraper returns to its original position under the action of the spring, the trapezoidal scraper will produce a short shaking action due to the elastic force of the spring. This shaking action helps to remove the seeds attached to the trapezoidal scraper and prevent them from accumulating.

[0023] To sum up, through the design of the above structure, the present application can, on the one hand, fully dry the seeds entering the device, and on the other hand, recover the grease on the surface of the seeds, which not only helps to keep the equipment clean, but also improves the utilization rate of the grease, and at the same time can effectively scrape the seeds on the outer wall of the installation shell and the inner wall of the outer shell.

The magnetic poles of the first magnet 37 and the fourth magnet 41 at one end close to each other are opposite. The first magnet 37 on the stirring blade 32 will be attracted by the fourth magnet 41 on the hollow rotating rod 31 during the rotation. This attraction will increase the rotation speed of the blade, thereby lifting the seeds during the seed stirring process and forming a certain parabolic path in the air, thereby achieving mixing and uniform distribution of the seeds.

[0039] The surface of the spiral blade 29 is provided with a plurality of oil guide grooves 30 (see the attached manual). Figure 8 As shown in the figure, a plurality of balls 36 are rotatably installed in the oil guide groove 30, and grooves are provided on the surface of the balls 36. The groove design on the balls 36 helps to better capture and drain the oil on the seeds.

A hot air blower 10 is fixedly installed on the right side inside the fixed shell 28. The hot air blower 10 is a prior art, and its specific structural design is not repeated here. The output end of the hot air blower 10 is connected to a plurality of spiral air outlet pipes 11, and the plurality of spiral air outlet pipes 11 surround the outside of the second oil storage tank 12, and the end of the spiral air outlet pipe 11 away from the hot air blower 10 is connected to the inside of the mounting shell 14 after passing through the right side wall of the mounting shell 14, so that the hot air ejected through the spiral air outlet pipe 11 can act well on the seeds, thereby increasing the movement speed and mixing uniformity of the seeds.

[0041] A first arc-shaped push plate 16 is provided on the right side of the shell 2 and is slidably sleeved on the outside of the mounting shell 14. A second arc-shaped push plate 17 is provided on the left side of the shell 2 and is slidably sleeved on the outside of the mounting shell 14. Notches are provided on the upper ends of the first arc-shaped push plate 16 and the second arc-shaped push plate 17, and a plurality of limit rods 27 are slidably penetrated between the first arc-shaped push plate 16 and the second arc-shaped push plate 17. Both ends of the limit rods 27 are fixedly connected to the inner wall of the shell 2. A first motor 7 is fixedly installed on the right side wall of the shell 2. A screw rod 13 is keyed to the output end of the first motor 7. The screw rod 13 is threadedly connected to the second arc-shaped push plate 17 after sliding through the right side wall of the shell 2 and the first arc-shaped push plate 16 in turn, so that when the first motor 7 is running, the second arc-shaped push plate 17 can be reciprocated left and right along the screw rod 13 and the limit rod 27 by driving the screw rod 13 to rotate, and a short brush is provided on the side of the second arc-shaped push plate 17. A second motor 8 is fixedly mounted on the right end side wall of the housing 2, and another screw rod 13 is keyed to the output end of the second motor 8. The screw rod 13 is threadedly connected to the first arc-shaped push plate 16 after sliding through the right side wall of the housing 2, and the end of the screw rod 13 away from the first motor 7 is slidably connected to the second arc-shaped push plate 17, so that when the second motor 8 is running, the screw rod 13 can be driven to rotate to make the first arc-shaped push plate 16 reciprocate left and right along the screw rod 13 and the limit rod 27.

[0042] The output end of the third motor 9 is fixedly sleeved with a first gear 23, one side of the first gear 23 is meshedly connected with a second gear 24, the second gear 24 is meshedly connected with an inner gear ring 20 sleeved on the outside thereof, a first transmission rod 21 is fixedly installed on the side of the inner gear ring 20, a rotating disk 25 fixedly sleeved on the output end of the third motor 9 is provided on the right side of the inner gear ring 20, and a second transmission rod 22 is fixedly installed on the side of the rotating disk 25, so that when the third motor 9 is running, the first transmission rod 21 and the second transmission rod 22 can be driven to rotate in opposite directions through the cooperation of the first gear 23, the second gear 24, the inner gear ring 20 and the rotating disk 25, and the first transmission rod 21 and the second transmission rod 22 can be driven to rotate in opposite directions. The ends of the two sets of springs 26 that are close to each other are fixedly connected to the partition, and the ends of the two sets of springs 26 that are away from each other are fixedly connected to the trapezoidal scraper 19 after sliding through the side wall of the shell 2. The trapezoidal scraper 19 is in sliding contact with the outer surface of the mounting shell 14, and the end of the trapezoidal scraper 19 that is close to the second magnet 39 is fixedly installed with a third magnet 40. The third magnet 40 and the end of the second magnet 39 that are close to each other have opposite magnetic poles, so that suction can be generated between the two. A baffle 43 for blocking the third magnet 40 is fixedly installed at the lower left end of the mounting shell 14.

[0043] A first oil storage tank 5 communicating with the interior is detachably installed on the right side below the outer shell 2, and a filter is installed at the connection between the two. A first discharge port 6 communicating with the interior is fixedly installed on the left side below the outer shell 2.

[0044] The specific working principle of the present invention is as follows: first, turn on the hot air blower 10 to preheat the entire device. After preheating for a period of time, pour the high-oil soybean seeds that need to be dried into the device from the feed port 3. At the same time, start the third motor 9 to drive the hollow rotating rod 31 to rotate, thereby driving the spiral blades 29 to rotate. The seeds that need to be dried will be stirred and transported by the spiral blades 29, and finally enter between the outer shell 2 and the mounting shell 14 from the second discharge port 15.

[0045] During the stirring and transporting process, the spiral blades 29 rotate at a relatively low speed, thus avoiding the damage or deformation of the seeds that may be caused by high-speed stirring. In the early stage of drying, due to the high moisture content inside the high-oil soybean seeds, its main task is to remove free moisture. Therefore, when the seeds just enter the interior of the installation shell 14, the spiral blades 29 will drive the seeds to rotate, and at the same time, the hot air ejected by the spiral air outlet pipe 11 will combine with the airflow generated by the rotation of the spiral blades 29 to form a uniform hot air, and the seeds are dried in all directions. When the seeds enter the interior of the installation shell 14 through the feed port 3, since the seeds are close to the spiral air outlet pipe 11, the hot air ejected by the spiral air outlet pipe 11 can act well on the seeds, increase the movement speed and mixing uniformity of the seeds, and this design makes the stirring and drying process more efficient, and can achieve an ideal stirring effect in a short time.

[0046] As the drying process proceeds, the moisture inside the seeds gradually decreases, and the grease begins to gradually precipitate. At this time, it is necessary to pay attention to collecting the grease precipitated from the seeds. Because during the drying process, if the grease is not collected, the grease will accumulate on the surface of the seeds, which will reduce the storage stability of the seeds. The greasy surface is easy to breed microorganisms and pests, causing the seeds to mold, deteriorate or be infested with insects. The activities of these microorganisms and pests will further accelerate the corruption process of the seeds and shorten the storage life of the seeds. In addition, by collecting these greases, they can be refined and used in multiple fields such as food processing, manufacturing and cosmetics, so as to maximize the utilization of resources and improve economic benefits. When the spiral blades 29 stir and transport the seeds, the seeds will push the stirring blades 32 to rotate so as to stir the seeds. At the same time, the bristles 38 on the stirring blades 32 can effectively remove the excess grease on the surface of the seeds, thereby playing a cleaning role. The bristles 38 are long and can cover a larger seed surface area, making the stirring process more uniform and comprehensive, which helps to ensure that each seed can be fully stirred, thereby improving the overall drying effect of the seeds. This force also helps to break the attachment state of the grease, making it easier to remove. When the stirring blade 32 rotates, the bristles 38 will hit the fixed rod 33 regularly, remove the seeds accumulated on the bristles 38, and keep the bristles 38 clean and flexible. In addition, the first magnet 37 on the stirring blade 32 will be attracted by the fourth magnet 41 on the hollow rotating rod 31 during the rotation process, and this attraction will accelerate the rotation speed of the blade, so that the seeds will be lifted up and formed in the air to form a certain parabolic path during the seed stirring process, so as to achieve the mixing and uniform distribution of the seeds, and this lifting effect helps to break the agglomeration state of the seeds caused by the precipitation of oil and improve the drying effect. In addition, the spiral blade 29 is also provided with an oil guide groove 30, and the oil guide groove 30 is equipped with a ball 36, and one end of the oil guide groove 30 is connected to the inside of the hollow rotating rod 31 through a pipeline. When the seeds are transported and stirred by the spiral blade 29, the ball 36 will apply a thrust to the seeds during the rotation process, causing them to roll or throw up, thereby achieving uniform mixing of the seeds and helping to break the agglomeration state of the seeds. In addition, the grease on the seeds can also reduce the friction resistance when the ball 36 rotates, making the ball 36 rotate more smoothly, which not only improves the mixing efficiency, but also reduces the wear and energy consumption of the equipment. The ball 36 is also provided with a groove, and the groove design on the ball 36 helps to better capture and drain the grease on the seeds. When the seeds roll on the ball 36, the grease will flow along the groove and eventually flow into the oil guide groove 30 on the spiral blade 29. A part of the grease flowing into the oil guide groove 30 flows into the hollow rotating rod 31, and finally flows into the second oil storage tank 12 through the oil scraper 35 driven by the electric telescopic rod 34, and a part of it flows into the third oil storage tank 42 through the mounting shell 14.Finally, the accumulation of grease on the spiral blades 29 and the seeds is avoided, which not only helps to keep the equipment clean but also improves the utilization rate of the grease.

[0047] The dried seeds eventually enter between the outer shell 2 and the mounting shell 14 from the second discharge port 15, and at this time, the grease on the surface of the seeds needs to be cleaned for a second time. Start the first motor 7, thereby driving the second arc-shaped push plate 17 to move back and forth. When the second arc-shaped push plate 17 moves back and forth, the arc-shaped plate moves back and forth to evenly spread the seeds, thereby achieving a breaking up effect. In addition, there are shorter brushes on the second arc-shaped push plate 17, and the shorter brushes have higher flexibility and elasticity, which enables them to fit tightly to the surface of the seeds, and then use the residual heat of the mounting shell 14 to effectively remove the grease attached to the seeds, and perform a second cleaning on the seeds. The grease brushed off will eventually flow into the first oil storage tank 5 through the filter groove at the bottom of the outer shell 2.

[0048] After the seeds are cleaned twice, the second motor 8 and the third motor 9 are started. The third motor 9 drives the inner gear ring 20 and the rotating disk 25 to rotate through the first gear 23 and the second gear 24, thereby driving the first transmission rod 21 to rotate clockwise and the second transmission rod 22 to rotate counterclockwise. Finally, the trapezoidal scraper 19 is driven to rotate on the outer wall of the mounting shell 14 and the inner wall of the shell 2 through the second magnet 39 and the third magnet 40, so that the seeds on the inner wall and the outer wall are effectively scraped off and concentrated at the bottom of the shell 2. When the first transmission rod 21 and the second transmission rod 22 rotate to the baffle 43, the third magnet 40 will be blocked and the second magnet 39 will continue to rotate. At this time, the spring 26 will drive the trapezoidal scraper 19 to move back. When the trapezoidal scraper 19 returns to its original position under the action of the spring 26, due to the elastic force of the spring 26, the trapezoidal scraper 19 will produce a short shaking action. This shaking action helps to remove the seeds attached to the trapezoidal scraper 19 and prevent them from accumulating. After the trapezoidal scraper 19 returns to its original position, the second motor 8 is started, thereby driving the first arc-shaped push plate 16 to push the seeds toward the first discharge port 6. After the first arc-shaped push plate 16 returns to its original position, the first transmission rod 21 and the second transmission rod 22, which have rotated one circle, will again pass through the second magnet 39 and the third magnet 40 to drive the trapezoidal scraper 19 to rotate. Through the alternating movement of the first arc-shaped push plate 16 and the trapezoidal scraper 19, the seeds on the inner and outer walls are effectively scraped off and finally discharged from the first discharge port 6.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
