Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, and more specifically, to a rice seed drying device. Background Art

[0002] Rice seeds are usually obtained by harvesting mature rice ears and then threshing them. Rice seeds may contain a certain amount of moisture after harvesting. High moisture content can easily lead to problems such as seed mold and decreased germination rate. Therefore, it is necessary to reduce the moisture content of the seeds by drying, reduce the growth of mold and bacteria, and protect the seed quality.

[0003] Current seed dryers use hot air or other heating methods to quickly evaporate the moisture in seeds and avoid deterioration of seed quality due to excessive temperature or improper humidity. However, when using a dryer, the seeds are usually laid on a sieve plate. When the number of seeds is too large, the seeds will stack on each other. Under the operation of the dryer, the moisture on the surface of the seeds is dried, while the moisture inside the seeds is difficult to dissipate due to the stacking of seeds, further reducing the drying efficiency. In order to ensure thorough drying, the drying time needs to be increased. Although the increase in drying time can expel moisture, long-term hot air drying will also damage the surface of the seeds, making it difficult to ensure the germination rate and growth ability of the seeds, reducing the seed quality and preservation performance, so it needs to be improved and optimized.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] like Figures 1 to 8 As shown, the utility model provides a rice seed drying device, including a drying machine box 1, characterized in that: a drying mechanism 2 is fixedly installed on the top of the drying machine box 1, a movable door 3 is rotatably installed on the left side of the drying machine box 1, a sieve plate 4 is movably arranged inside the drying machine box 1, and one end of the sieve plate 4 is rotatably installed on the inner wall of the drying machine box 1; it also includes:

[0032] The driving mechanism is fixedly installed inside the drying machine box 1 and is located below the screen plate 4;

[0033] The stir-frying mechanism is fixedly mounted on the bottom of the sieve plate 4, and one end of the stir-frying mechanism is fixedly sleeved with the driving mechanism;

[0034] The control mechanism is fixedly mounted on the inner wall of the drying machine box 1, and one end of the control mechanism is fixedly connected to the driving mechanism;

[0035] The lifting mechanism is rotatably mounted on the inner wall of the drying machine box 1, and one end of the lifting mechanism is drivingly connected to the control mechanism;

[0036] The stir-fry mechanism includes a bottom plate 5 fixedly mounted on the bottom of the sieve plate 4, a vibration head 12 is movably mounted inside the bottom plate 5, one end of the vibration head 12 is in contact with the bottom of the sieve plate 4, the other end of the vibration head 12 is fixedly connected to the pressing plate 11, and the pressing plate 11 and the bottom plate 5 are elastically connected via a spring 13;

[0037] There are two groups of stir-frying mechanisms, which are fixedly installed on the front and rear sides of the bottom of the sieve plate 4. The stir-frying mechanism also includes a driving block 10 fixedly sleeved with one end of the driving mechanism, and the driving block 10 and the pressing plate 11 are in conflict with each other.

[0038] When it is necessary to dry the rice seeds, the staff first lays the seeds on the top of the sieve plate 4, and then closes the movable door 3. At this time, the top of the movable door 3 will squeeze the fixed head 23, so that the fixed head 23 will shrink into the storage bin 22. At this time, the spring 25 is compressed. When the movable door 3 and the drying machine box 1 are completely closed, the elastic potential energy of the spring 25 drives the fixed head 23 to reset, so that the fixed head 23 fixes the movable door 3. Then the staff starts the drying mechanism 2 and the double-axis motor 6 to start the drying operation. The operation of the double-axis motor 6 drives the worm 7 to rotate, and the rotation of the worm 7 drives the worm gear 8 to rotate. At this time, the worm gear 8 drives the driving block 10 fixedly connected to the transmission rod 9 to rotate, so that the pressure plate 11 lifts the vibration head 12 upward, and further makes the vibration head 12 drive the sieve plate 4 to move, so that the seeds on the surface of the sieve plate 4 begin to stir-fry. When the driving block 10 rotates, the elastic potential energy of the spring 13 is used to make The pressing plate 11 always conflicts with the driving block 10. When the transmission rod 9 rotates, the ratchet 15 inside the transmission bin 14 starts to rotate. Due to the characteristics of the ratchet 15, the brake block 16 and the ratchet 15 are out of the braking state at this time, and the worm gear 18 fails to rotate together. When the drying operation is completed, the staff pulls the pull rod 24 to retract the fixed head 23 into the storage bin 22. At this time, the movable door 3 can be opened, and then the staff reverses the dual-axis motor 6 to make the transmission rod 9 rotate in the opposite direction.

At this time, the brake block 16 and the ratchet 15 are squeezed by the brake block 16, so that the brake block 16 and the ratchet 15 are meshed with each other. At this time, the worm gear 18 and the ratchet 15 rotate together, and the rotation of the worm gear 18 drives the worm gear 19 to rotate. The rotation of the worm gear 19 drives the connecting rod 21 to rise, thereby driving one end of the sieve plate 4 to rise, so that the sieve plate 4 is in a tilted state. At this time, the seeds on the top of the sieve plate 4 will flow out from the movable door 3 to complete the collection.

[0039] Through the operation of the dual-axis motor 6, the worm 7 drives the worm wheel 8 to rotate, and the driving block 10 is further rotated to drive the pressure plate 11 to lift the vibration head 12 upward. At this time, the sieve plate 4 begins to shake up and down to stir-fry the seeds. Then, through the reversal of the dual-axis motor 6, the ratchet 15 drives the worm 2 18 to rotate. At this time, the sieve plate 4 is in an inclined state, which is convenient for collecting seeds. Compared with the traditional device, the device, through the operation of the driving mechanism, the stir-frying mechanism disturbs the seeds on the surface of the sieve plate 4 to avoid the accumulation of seeds, so that the drying effect of the drying mechanism 2 is better. When the drying operation is completed, the driving mechanism is reversed to make the lifting mechanism drive the sieve plate 4 to tilt, which is convenient for collecting seeds and improves work efficiency.

When the movable door 3 and the drying machine box 1 are completely closed, the elastic potential energy of the spring 25 drives the fixed head 23 to reset, so that the fixed head 23 fixes the movable door 3. When the drying operation is completed, the staff pulls the pull rod 24 to retract the fixed head 23 into the storage bin 22. At this time, the movable door 3 can be opened.

[0043] The force generated by the closing of the movable door 3 causes the fixed head 23 to retract into the storage bin 22, and then the elastic potential energy of the spring 25 drives the fixed head 23 to reset, so that the fixed head 23 fixes the movable door 3.

[0047] When the dual-axis motor 6 reverses, the transmission rod 9 rotates in the opposite direction, and the reverse rotation of the transmission rod 9 drives the ratchet 15 to reverse. At this time, the brake block 16 is squeezed to make the brake block 16 and the ratchet 15 mesh with each other, and the worm 18 and the ratchet 15 rotate together.
