Description

Technical Field

[0001] This application relates to the field of soybean storage technology, and in particular to a soybean storage bin unloading mechanism. Background Technology

[0002] In the storage and subsequent processing of soybeans, the unloading process of the storage silo is crucial. Most existing soybean storage silo unloading mechanisms involve transporting soybeans to the silo using a forklift, then directly unloading them onto a conveyor belt for transport. Conventional unloading structures are simple, relying solely on gravity flow, which often results in inconsistent outflow speeds and difficulty in precisely controlling the unloading volume. This makes it impossible to achieve quantitative unloading via conveyor belt transport. Furthermore, when the unloading port needs to stop, soybeans are easily jammed, leading to crushing and resource waste. The inability to control the material discharge speed also makes it difficult to immediately stop the machine in case of malfunction. Utility Model Content

[0003] To address the problems of conventional soybean storage silos relying solely on gravity flow for feeding, which results in inaccurate feeding, easy jamming, and difficulty in speed control, this application provides a soybean storage silo feeding mechanism.

[0004] The soybean storage bin unloading mechanism provided in this application adopts the following technical solution:

[0005] A soybean storage bin feeding mechanism includes a storage bin, a feeding assembly at the bottom of the storage bin, the feeding assembly including a housing at the lower end of the storage bin, a reducing pipe inside the housing, spiral blades adapted to the reducing pipe on the inner side of the reducing pipe, and an anti-clogging assembly inside the storage bin.

[0006] Preferably, the shell is connected to the bottom of the storage compartment, and the shell is also provided with a discharge valve, which is located at one end of the rotating shaft.

[0007] Preferably, a rotating shaft is rotatably disposed inside the housing, the helical blades are disposed on the housing, and one end of the rotating shaft passes through the housing and is connected to a drive motor.

[0008] Preferably, the anti-blocking component includes a sliding plate vertically disposed in the storage compartment, and a plurality of toggle levers are disposed on the outer side of the sliding plate.

[0009] Preferably, the sliding plate is provided with a sliding groove, and a plurality of guide rods are provided in the sliding groove. A spring telescopic rod is provided between the guide rod and the sliding plate, and the spring telescopic rod extends and retracts vertically.

[0010] Preferably, the bottom of the sliding plate is provided with a spherical surface, and the spiral blade is provided with reinforcing ribs on the lower side of the sliding plate.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By using the feeding assembly, unloading valve, drive motor, and anti-clogging assembly in combination, the drive motor drives the spiral blades to rotate inside the variable diameter pipe, which can better control the flow of soybeans, making the feeding more uniform and stable, thereby improving the feeding accuracy. At the same time, the rotation of the spiral blades pushes the shell upward, realizing the reciprocating movement of the sliding plate and the actuating rod, ensuring stable feeding and preventing blockage. Compared with the existing technology, it has the effects of uniform and accurate feeding and significant anti-clogging effect. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0018] This application discloses a soybean storage bin unloading mechanism. (Refer to...) Figure 1-3 A soybean storage bin feeding mechanism mainly consists of a storage bin 1, a feeding component 2, a discharge valve 3, a drive motor 4, and an anti-blocking component 5. It achieves uniform and accurate feeding of soybeans from the storage bin, while effectively preventing blockages and ensuring the smooth progress of the feeding process.

[0019] Reference Figure 1 Storage compartment 1, serving as a storage container for soybeans, has an internal coating made of food-grade moisture-proof and rust-proof paint, which further ensures the quality and safety of soybeans and extends their shelf life.

[0020] Reference Figure 3The feeding assembly 2 is located at the bottom of the storage bin 1 and includes a housing 201, a rotating shaft 202, a reducing pipe 203, and a spiral blade 204. The housing 201 is made of cast iron or high-strength aluminum alloy. Cast iron is lower in cost and has good wear resistance, making it suitable for scenarios with strict cost control and certain wear resistance requirements. Aluminum alloy is lightweight and easy to install and maintain, offering significant advantages in situations requiring frequent disassembly and maintenance or where the overall weight of the equipment is a concern. The housing 201 is connected to the bottom of the storage bin 1, providing a channel for soybeans to enter the feeding stage from the storage bin. A discharge valve 3 is installed on it, located at one end of the rotating shaft 202. It can be an electric gate valve or a pneumatic butterfly valve. The valve body material must be compatible with the medium (soybeans), with good sealing performance. The control accuracy and reliability of the electric or pneumatic actuator must meet production requirements, ensuring that the discharge valve 3 can be precisely controlled when opening and closing, guaranteeing smooth feeding and preventing soybean leakage.

[0021] Reference Figure 3 A rotating shaft 202 is rotatably mounted inside the housing 201. The rotating shaft 202 is made of high-quality alloy steel, which enables it to withstand the torque transmitted by the rotating helical blade 204, ensuring long-term stable operation. The connection between the rotating shaft 202 and the helical blade 204 is welded. This connection method ensures reliable power transmission and avoids problems such as slippage and loosening during operation, ensuring that the helical blade 204 can rotate synchronously and stably with the rotating shaft 202.

[0022] Reference Figure 3 The reducing pipe 203 is made of seamless steel pipe. The pipe diameter change is designed based on the flow characteristics of soybeans and the uniform feeding requirements. The larger diameter at the inlet facilitates smooth soybean entry, while the gradually decreasing diameter at the outlet utilizes fluid mechanics principles to increase and more uniform the flow velocity of soybeans as they pass through the reducing pipe 203, laying the foundation for precise feeding. Its smooth inner wall reduces the flow resistance of soybeans, ensuring smooth flow within the pipe and improving feeding efficiency. The spiral blades 204 are made of stainless steel, formed through stamping and welding processes to ensure strength and wear resistance. Their surface can be polished to further reduce the coefficient of friction with soybeans, allowing the spiral blades 204 to more easily propel the soybeans forward during rotation. This enables precise control of the soybean feeding speed and flow rate, resulting in more uniform and stable feeding, thereby improving feeding accuracy.

[0023] Reference Figure 1 The drive motor 4 selects an appropriate power according to the material feeding requirements, is installed on the outside of the housing 201, and is connected to the rotating shaft 202 for transmission. It provides a power source for the rotation of the rotating shaft 202 and the spiral blade 204, driving the entire material feeding process. By reasonably adjusting the motor power and speed, it can adapt to the requirements of different material feeding amounts.

[0024] Reference Figure 3The anti-blocking component 5 is located inside the storage compartment 1 and includes a sliding plate 501, guide rods 502, spring telescopic rods 503, and a lever 504. The sliding plate 501 has a groove containing several guide rods 502. The guide rods 502 are made of stainless steel to ensure precision and smoothness, providing accurate guidance for the vertical movement of the sliding plate 501 and preventing deviation or jamming during movement. The spring telescopic rod 503 is located between the guide rods 502 and the sliding plate 501, extending and retracting vertically. Its spring is made of high-quality spring steel and heat-treated to improve elasticity and fatigue life. The telescopic rod portion uses aluminum alloy or stainless steel tubing to ensure structural strength and stability. The elastic coefficient is designed based on the stacking pressure of soybeans and the movement requirements of the sliding plate 501, ensuring sufficient support for the sliding plate 501 to return to its original position while allowing smooth movement under load. The agitator 504 on the outer side of the sliding plate 501 is made of stainless steel or plastic and is designed to facilitate the stirring of soybeans. As the sliding plate 501 moves vertically back and forth, the agitator 504 continuously stirs the soybeans in the storage bin 1, preventing them from accumulating and clogging at the bottom of the bin and ensuring continuous feeding. Simultaneously, the spherical surface design at the bottom of the sliding plate 501 reduces friction with the soybeans, making its movement more flexible, while the reinforcing ribs on the spiral blades 204 improve the blades' strength and wear resistance, ensuring they will not deform or break during prolonged soybean feeding.

[0025] The implementation principle of a soybean storage bin unloading mechanism according to an embodiment of this application is as follows:

[0026] In operation, when soybeans need to be discharged from storage bin 1, first open the discharge valve 3. Select the appropriate valve type according to the automation configuration and control requirements of the storage facility to allow the soybeans in storage bin 1 to enter the housing 201. Next, start the drive motor 4, select the appropriate power and speed, and the drive motor 4 drives the rotating shaft 202 to rotate. The spiral blades 204 on the rotating shaft 202 rotate synchronously. The soybean discharge is controlled by the reducing pipe 203 and the spiral blades 204. At the same time, the rotation of the spiral blades 204 pushes the housing 201 upward, which drives the anti-blocking component 5 to work and prevent blockage.
