Description

Technical Field

[0001] This invention relates to the field of rice processing, and more particularly to a rice storage silo. Background Technology

[0002] Rice, referring to the unhulled grains, belongs botanically to the subspecies of *Oryza sativa* within the genus *Oryza* of the family Poaceae. It is an annual plant, 50–130 cm tall, with the main stem branching into several tillers at the base. Each tiller produces a panicle-shaped flower cluster, each cluster bearing 50–500 spikelets, and each spikelet yields one grain (rice). Rice is one of my country's most important grain crops, accounting for approximately one-quarter of the total grain crop area and about half of the national grain output. Rice can be processed into various foods, and some manufacturers typically purchase large quantities for future use. Before processing, this rice is usually stored in warehouses.

[0003] Patent application number CN202021824421.3 discloses a combined rice storage silo, including an elevator, multiple identical rice silos, a screw conveyor and a guide belt connecting the multiple rice silos in sequence. The upper outlet of the elevator is connected to the inlet of the screw conveyor. The screw conveyor is positioned above the multiple rice silos, and each rice silo has a connection port at its top, with a solenoid valve installed at each connection port. A buffer plate is inclined on one side of the inside of each rice silo, and a support rod is provided on the bottom surface of the buffer plate. One end of the support rod is equipped with a spring connected to the buffer plate, and the other end is fixedly connected to the inner wall of the rice silo. A discharge port is provided at the bottom of each rice silo, and the discharge port of each rice silo is connected to the guide belt. A rotating shaft is provided above the discharge port, and rotating blades are provided on the rotating shaft. A rotating motor is provided at one end of the rotating shaft extending out of the rice silo. However, this type of rice storage silo lacks a ventilation device, and the heat generated by the rice's respiration cannot be dissipated in time, causing heat accumulation and easily burning the rice.

[0004] This invention was developed to address the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rice storage bin.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses a rice storage bin, comprising a bin body fixed on a support frame. A feed pipe is fixed to the top of the bin body, and a conveying pipe is fixed to the bottom of the bin body. A conveying shaft is installed inside the conveying pipe and is driven to rotate by a conveying motor. A spiral conveying blade is fixed on the conveying shaft. A lifting pipe is vertically fixed to the bin body at the end of the conveying pipe. A lifting shaft is installed inside the lifting pipe and is driven to rotate by a lifting motor. A spiral lifting blade is fixed on the lifting shaft. The top of the lifting pipe is also connected to the bin body via a return pipe. Air outlet pipes are evenly fixed to the bin body, and air outlet holes are evenly arranged on the air outlet pipes inside the bin body. The ends of the air outlet pipes are all connected to air inlet pipes, and an air pump is fixed to the end of the air inlet pipe. A discharge pipe with a valve is also fixed to one side of the bottom of the conveying pipe.

[0008] Preferably, the return pipe is inclined.

[0009] Preferably, a vent pipe is also fixed to the top of the chamber. Airflow is discharged from the chamber through the vent pipe.

[0010] Preferably, a baffle is fixed to the silo at the location of the vent pipe. The baffle has a U-shaped structure, and the vent pipe is disposed inside the baffle. By setting the U-shaped baffle to fasten onto the vent pipe and placing the vent pipe inside the baffle, it is possible to prevent the rice from being submerged in the vent pipe and thus avoid the rice clogging the vent and affecting the use of the device.

[0011] Preferably, a base plate is fixedly inclined at the bottom of the silo on both sides of the conveying pipe, and a feed inlet penetrating the conveying pipe is provided at the end of the base plate at the position of the conveying pipe. The feed inlet on the conveying pipe is located at the lowest position in the silo, and the feed inlet is located at the upper and lower halves of the conveying pipe, which can prevent the conveying pipe from being filled with rice and prevent the rice from being excessively squeezed and damaged when the spiral conveyor blades rotate.

[0012] Compared with existing technologies, the present invention has the following advantages:

[0013] After the rice has been stored for a period of time, a clean and dry gas is extracted by an air pump and sprayed out through the air outlets on each air outlet pipe. The gas flows upward between the rice grains, carrying away the heat between them. This device also enables the rice grains to flow within the storage chamber. When the rice grains flow, the gaps between adjacent rice grains increase, which facilitates the flow of the gas sprayed from the air outlets between the rice grains, making it easier to carry away the heat from the rice grains and preventing them from burning.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0022] Example 1:

[0023] like Figures 1 to 5As shown, this embodiment discloses a rice storage bin, including a bin body 1 fixed on a support. A feed pipe 3 is fixed to the top of the bin body 1, and a conveying pipe 4 is fixed to the bottom of the bin body 1. A conveying shaft 5 is installed inside the conveying pipe 4. The conveying shaft 5 is driven to rotate by a conveying motor 7. A spiral conveying blade 6 is fixed on the conveying shaft 5. A lifting pipe 8 is vertically fixed to the bin body 1 at the end of the conveying pipe 4. A lifting shaft 9 is installed inside the lifting pipe 8. The lifting shaft 9 is driven to rotate by a lifting motor 11. A spiral lifting blade 10 is fixed on the lifting shaft 9. The top of the lifting pipe 8 is also connected to the bin body 1 through a return pipe 12. An air outlet pipe 16 is also evenly fixed to the bin body 1. Air outlet holes 17 are evenly arranged on the air outlet pipe 16 inside the bin body 1. The ends of the air outlet pipe 16 are all connected to the air inlet pipe 15. An air pump is fixed to the end of the air inlet pipe 15. A discharge pipe 19 with a valve is also fixed to one side of the bottom of the conveying pipe 4. The rice to be stored is fed into the silo 1 through the feed pipe 3. After the rice is stored for a period of time, pure and dry gas is extracted by an air pump and sprayed out through the air outlets 17 on each air outlet pipe 16. The gas flows upward between the rice grains, carrying away the heat between them. When the rice cools down, the conveyor motor 7 is powered on, driving the conveyor shaft 5 to rotate and the spiral conveyor blade 6 to rotate. Due to the spiral curved surface characteristics of the spiral conveyor blade 6, when the spiral conveyor blade 6 rotates, it pushes the rice at the bottom to the bottom of the lifting pipe 8. The lifting motor 11 drives the lifting shaft 9 to rotate. When the lifting shaft 9 rotates, the spiral lifting blade 10 rotates. The rice at the bottom of the lifting pipe 8 rises with the spiral lifting blade 10 and returns to the silo 1 through the return pipe 12, realizing the flow of rice in the silo 1. When the rice flows, the gap between adjacent rice grains increases, which facilitates the flow of gas sprayed from the air outlets 17 between the rice grains, making it easier to carry away the heat on the rice and prevent the rice from burning.

[0024] The return pipe 12 is inclined.

[0025] The bottom of the silo 1 on both sides of the conveying pipe 4 is fixed with a base plate 13 at an inclination. The conveying pipe 4 at the end of the base plate 13 is provided with a feed inlet 14 that passes through the conveying pipe 4. The feed inlet 14 on the conveying pipe 4 is located at the lowest position inside the silo 1. The feed inlet 14 is located in the upper and lower half of the conveying pipe 4, which can prevent the rice from filling the conveying pipe 4 and prevent the rice from being excessively squeezed and damaged when the spiral conveyor blade 6 rotates.

[0026] Example 2:

[0027] This embodiment discloses a rice storage bin. Based on the structure and principle of Embodiment 1, the top of the bin body 1 in this embodiment is further fixed with a vent pipe 2. Airflow is discharged from the bin body 1 through the vent pipe 2.

[0028] Example 3:

[0029] This embodiment discloses a rice storage bin. Based on the structure and principle of Embodiment 1 or Embodiment 2, in this embodiment, a baffle 18 is fixed on the bin body 1 at the location of the vent pipe 16. The baffle 18 has a U-shaped structure, and the vent pipe 16 is disposed inside the baffle 18. By setting the U-shaped baffle 18 to fasten onto the vent pipe 16, and by placing the vent pipe 16 inside the baffle 18, it is possible to prevent rice from being submerged at the location of the vent pipe 16, thus preventing rice from clogging the vent hole 17 and affecting the use of the device.
