Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice seed storage technology, and in particular to a rice seed storage device. Background Technology
[0002] Rice seed storage is a crucial link in agricultural production and germplasm resource protection, and its quality directly affects germination rate, planting efficiency, and variety continuation. However, traditional storage methods (such as burlap sacks, woven bags, and ordinary warehouses) have the following problems: the storage device cannot be ventilated, and the seeds release heat and evaporate moisture inside the storage device, leading to increased temperature and humidity inside the storage chamber. This causes the seeds to mold or even die, thus affecting the germination rate and reducing rice yield. Therefore, a rice seed storage device needs to be developed. Utility Model Content
[0003] The purpose of this invention is to provide a rice seed storage device to solve the technical problems mentioned in the background section.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] This utility model discloses a rice seed storage device, comprising a storage tank, a seed inlet hopper inclinedly arranged on the outer peripheral wall of the storage tank, an air inlet pipe fixedly arranged in the middle of the bottom plate of the storage tank, the lower end of the air inlet pipe being connected to the output end of a blower fixedly arranged at the lower part of the bottom plate of the storage tank, the upper end of the air inlet pipe extending into the interior of the storage tank, a motor fixedly arranged in the middle of the upper part of the storage tank, the power output end of the motor being connected to a drive shaft rotatably arranged below the bottom plate of the storage tank, the lower end of the drive shaft being fixedly connected to the upper part of a rotating drum, the lower end of the rotating drum being rotatably engaged with the upper end of the air inlet pipe, and a rotating sealing ring being provided at the contact point between the two, and a plurality of pairs of air outlet stirring rods communicating with the interior of the rotating drum being evenly arranged on the peripheral wall of the rotating drum, and a plurality of air outlet holes being evenly opened on the peripheral wall of each air outlet stirring rod.
[0006] Furthermore, multiple support legs are evenly fixedly installed on the lower part of the bottom plate of the storage tank near the outer edge.
[0007] Furthermore, the bottom plate of the storage tank is fixedly provided with a seed outlet cylinder that communicates with the interior of the storage tank at the position between the support leg and the air inlet pipe, and a matching on / off valve is provided in the middle of the seed outlet cylinder.
[0008] Furthermore, the upper part of the seed hopper is hinged with a movable cover plate that matches the contour of its opening end.
[0009] Furthermore, each of the air outlets is fixedly equipped with an intercepting net.
[0010] Furthermore, the top plate of the storage tank is provided with a plurality of vent holes evenly distributed along the circumference, and each vent hole is provided with a vent mesh.
[0011] Furthermore, a drive gear is provided in the middle of the drive shaft, and multiple vertical driven shafts are uniformly rotatably arranged in the lower part of the top plate of the storage tank.

[0021] like Figures 1-5 As shown, a rice seed storage device includes a storage tank 1. A seed inlet hopper 2, which is inclinedly arranged on the outer peripheral wall of the storage tank and communicates with its interior, can be used to put rice seeds to be stored into the storage tank. A movable cover plate 3, which is adapted to the contour of its opening end, is hinged to the upper part of the seed inlet hopper 2. The movable cover plate 3 can be closed after the seeds are put in.
[0022] An air inlet pipe 4 is fixedly installed in the middle of the bottom plate of the storage tank 1. The lower end of the air inlet pipe 4 is connected to the output end of a blower 5 fixedly installed at the lower part of the bottom plate of the storage tank 1. The upper end of the air inlet pipe extends into the interior of the storage tank 1. A motor 6 is fixedly installed in the middle of the upper part of the storage tank 1. The power output end of the motor 6 is connected to a drive shaft 7 rotatably installed below the bottom plate of the storage tank 1. The lower end of the drive shaft 7 is fixedly connected to the upper part of a rotating drum 8. The lower end of the rotating drum 8 rotatably engages with the upper end of the air inlet pipe 4, and a rotary sealing ring 9 is installed at the contact point between the two. The rotating drum 8 has multiple pairs of horizontal, interconnected air-discharging stirring rods 10 evenly arranged on its peripheral wall. Each air-discharging stirring rod 10 has multiple air-discharging holes 11 evenly opened on its peripheral wall, and each air-discharging hole 11 is fixedly provided with an intercepting net 12. The intercepting net 12 can effectively prevent rice seeds in the storage tank 1 from entering the air-discharging stirring rod and the interior of the rotating drum through the air-discharging hole.
[0023] The top plate of the storage tank 1 is provided with a plurality of vent holes 13 evenly distributed along the circumference, and each vent hole 13 is fixedly provided with a vent mesh 14.
[0024] In practical use, this invention stores rice seeds in a storage tank. The motor and blower are periodically turned on. After the motor starts, it drives the drive shaft, the rotating drum, and multiple pairs of air-discharging stirring rods to rotate synchronously, thereby stirring the rice seeds in the storage tank. At the same time, the blower draws outside air through the air inlet pipe into the rotating drum, and then through the air outlets on each of the air-discharging stirring rods 10 into the storage tank. This, together with the vents at the top of the storage tank, ventilates the rice seeds in all parts of the storage tank, thus preventing mold or even death of the seeds due to increased temperature and humidity inside the storage tank, and ensuring the germination rate of the rice seeds after storage.
[0025] Multiple support legs 15 are evenly fixedly installed on the lower part of the bottom plate of the storage tank 1 near the outer edge, and the multiple support legs 15 can ensure the height of the storage tank 1 above the ground.
[0026] The bottom plate of the storage tank 1 has a seed outlet cylinder 16 fixedly installed at the position between the support leg 15 and the air inlet pipe 4, which communicates with the inside of the cylinder. A matching on / off valve 17 is installed in the middle of the seed outlet cylinder 16. Under normal storage conditions of rice seeds, the on / off valve 17 is in the closed state. When rice seeds need to be taken out of the storage tank for purposes such as sowing, the on / off valve can be opened to allow the rice seeds to flow out of the storage tank automatically under the action of gravity.
[0027] Furthermore, as a further improvement to this utility model, a drive gear 18 is installed in the middle of the drive shaft 7, and multiple vertical driven shafts 19 are evenly rotatably mounted circumferentially on the lower part of the top plate of the storage tank 1. Each driven shaft 19 is equipped with a driven gear 20 that meshes with the drive gear 18. Multiple pairs of auxiliary stirring rods 21 are evenly fixedly installed on each driven shaft 19 below the driven gear 20, and these pairs of auxiliary stirring rods 21 are staggered with the multiple pairs of air-discharging stirring rods 10. When the motor drives the drive shaft to rotate, the meshing transmission of the drive gear and each driven gear causes each driven shaft and each auxiliary stirring rod to rotate, thereby agitating the rice seeds near the periphery of the storage tank, further improving the contact efficiency between the rice seeds inside the storage tank and the external airflow, thus ensuring ventilation.
[0028] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
