Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a rice feeding cylinder control structure, including:

[0032] Brown rice hopper 1 is equipped with a rice feeding cylinder control mechanism. It should be noted that, through the rice feeding cylinder control mechanism, the PLC controls the cylinder's action in real time according to the actual working status of the rice machine, which can accurately adjust the opening and closing degree of the brown rice hopper insert plate, thereby achieving precise control of the rice feeding amount and improving the quality and stability of rice processing.

[0033] The rice feeding cylinder control mechanism includes a cylinder bracket 2, a brown rice hopper insert plate cylinder 3, a brown rice hopper insert plate 4, a connecting hole 5, and an adjustment component;

[0034] The brown rice hopper insert plate cylinder 3 is fixedly installed on the cylinder bracket 2. The output end of the brown rice hopper insert plate cylinder 3 is fixedly provided with a connecting screw head 12. A matching nut is fixedly sleeved on the outside of the connecting screw head 12. A tightening nut 13 is threadedly connected to the outside of the connecting screw head 12. The connecting screw head 12 is detachably connected to the brown rice hopper insert plate 4 through the matching nut and the tightening nut 13. A connecting hole 5 is opened on the brown rice hopper insert plate 4.

[0035] It should be noted that a PLC programmable logic controller is used as the core control unit. The PLC is connected to other working status monitoring modules of the rice machine, which can obtain the actual working status information of the rice machine in real time, such as the speed of the rice machine and the processing load. Based on this information, the PLC sends a command to the brown rice hopper insert plate cylinder 3 according to the preset value to control the brown rice hopper insert plate 4 to open or close, thereby accurately controlling the amount of brown rice fed.

[0036] The adjustment assembly includes a brown rice hopper feed pipe 6, a rotating shaft 7, an adjusting plate 8, and a screw 9. The brown rice hopper feed pipe 6 is fixedly installed at the bottom of the brown rice hopper 1, the rotating shaft 7 is rotatably installed on the brown rice hopper feed pipe 6, the adjusting plate 8 is fixedly installed on the rotating shaft 7, and the screw 9 is threadedly installed on the brown rice hopper feed pipe 6.

[0037] By adjusting the position of the screw 9 by rotating the screw 9, the brown rice impacts the adjusting plate 8 when it is fed, causing the adjusting plate 8 to rotate and come into contact with the screw 9. In this way, the flow rate can be controlled by adjusting the position of the screw 9.

[0038] Specifically, a guide frame 10 is fixedly installed on the top of the cylinder bracket 2, and the brown rice hopper insert plate 4 is slidably installed on the guide frame 10. The guide frame 10 is fixedly connected to the brown rice hopper 1. It should be noted that this allows the brown rice hopper insert plate 4 to move horizontally and stably.

[0039] Specifically, the bottom of the brown rice hopper 1 is provided with a discharge hole, which is connected to the discharge pipe 6 of the brown rice hopper. It should be noted that this facilitates the discharge of brown rice through the discharge pipe 6 of the brown rice hopper.

[0040] Specifically, the adjusting plate 8 is located inside the brown rice hopper feed pipe 6, and the screw 9 is in contact with the adjusting plate 8. It should be noted that the screw 9 can limit the adjustment plate 8.

[0041] Specifically, a manual lever 11 is fixedly installed on the brown rice hopper insert plate 4. The manual lever 11 is horizontally slidably installed on the brown rice hopper 1. It should be noted that the brown rice hopper insert plate 4 can be operated manually.

[0042] Working principle:

[0043] S1: When the fully automatic rice machine starts and begins to work, various status monitoring modules on the rice machine, such as speed sensors and load sensors, collect the working status information of the rice machine in real time and transmit this information to the PLC in the rice feed switch control module. The PLC analyzes and processes the received information to determine the amount of brown rice required for the current rice machine. For example, when the rice machine speed is high and the load is low, it means that the rice machine has a strong processing capacity. The PLC will control the brown rice hopper insert plate cylinder 3 to open the brown rice hopper insert plate 4 to a larger degree, increasing the amount of brown rice fed. Conversely, when the rice machine speed is low or the load is high, the PLC will control the brown rice hopper insert plate cylinder 3 to reduce the opening of the brown rice hopper insert plate 4, reducing the amount of rice fed.

[0044] S2: During the operation of the brown rice hopper insert plate cylinder 3, the brown rice hopper insert plate 4 is driven to slide horizontally at the feeding hole. When the cylinder piston extends, the brown rice hopper insert plate 4 opens, and brown rice flows out from the brown rice hopper 1 into the rice machine. When the cylinder piston retracts, the brown rice hopper insert plate 4 closes, stopping the rice feeding. Through this working process, this rice feeding cylinder control structure can adjust the rice feeding amount in real time and accurately according to the actual working state of the rice machine, ensuring the stable and efficient operation of the rice machine and improving the quality and production efficiency of rice processing.

[0045] S3: By rotating the screw 9, the position of the screw 9 is adjusted. When the brown rice is fed, it will impact the adjusting plate 8, causing the adjusting plate 8 to rotate and come into contact with the screw 9. In this way, the flow rate can be controlled by adjusting the position of the screw 9.

[0046] S4: Alternatively, the locking nut 13 can be unscrewed to release the restriction on the brown rice hopper insert plate 4. At this time, the brown rice hopper insert plate 4 can be manually operated by the manual lever 11 to meet the usage needs under different conditions.

[0047] The foregoing has provided a detailed description of the rice feeding cylinder control structure of this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
