Description

Technical Field

[0001] This utility model relates to a stopping device, specifically an infrared sensing stopping device for corn conveying. Background Technology

[0002] In modern agriculture and agricultural product processing, automated corn conveying is a crucial step in improving production efficiency and reducing labor costs. Currently, most common corn conveying equipment operates continuously, lacking precise control over the conveying process. When it is necessary to pause corn conveying or process specific batches of corn, manual operation to shut down the conveyor belt is often required. This method is not only inefficient but also prone to corn accumulation due to operational delays, leading to crushing and damage, and affecting product quality.

[0003] In addition, some existing automatic conveying stop devices are either complex in structure and expensive, and the corn will still roll due to its own inertia when the conveying stops, which is not conducive to stopping the corn conveying. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides an infrared sensing stop device for corn conveying, which effectively solves the problems mentioned in the background art.

[0025] The following is in conjunction with the appendix Figure 1-3 The specific embodiments of this utility model will be described in further detail.

[0026] Example 1, by Figure 1-3 This utility model provides an infrared sensing stop device for corn conveying, comprising:

[0027] Rack 1;

[0028] The conveyor belt 3 is rotatably connected to the inside of the frame 1;

[0029] Infrared sensor 4 is installed on one side of the travel path of conveyor belt 3;

[0030] Control unit 5 is electrically connected to infrared sensor 4;

[0031] A blocking mechanism 6 is located downstream of the infrared sensor 4. The blocking mechanism 6 includes a support frame 7 spanning the conveyor belt 3, a linear driver 8 mounted on the support frame 7, and a baffle 9 driven to rise and fall by the linear driver 8.

[0032] A height gap is formed between the lower surface of the baffle 9 and the bearing surface of the conveyor belt 3, and the height gap is smaller than the minimum diameter of the corn to be conveyed;

[0033] The control unit 5 is configured to control the linear actuator 8 to drive the baffle 9 to descend to the working position when the infrared sensor 4 detects a corn shading signal.

[0034] Frame 1: Frame 1 is the main support structure of the entire device. It is equipped with self-locking casters 2 at the bottom for easy movement and fixation of the device. Locking the casters 2 ensures the stability of the device during operation; unlocking allows the device to be easily moved to the desired position.

[0035] Conveyor belt 3: Conveyor belt 3 is rotatably connected to the inside of frame 1 and is driven by motor 12 mounted on frame 1. Motor 12 provides power to drive conveyor belt 3 to rotate, thereby realizing continuous conveying of corn.

[0036] Infrared sensor 4: Infrared sensor 4 is installed on one side of the conveyor belt 3's travel path. Its function is to detect in real time whether corn is passing on the conveyor belt. When corn blocks the infrared signal emitted by infrared sensor 4, the sensor will transmit the detection signal to control unit 5.

[0037] Control Unit 5: Control Unit 5 is electrically connected to Infrared Sensor 4 and receives the detection signal from Infrared Sensor 4. Simultaneously, Control Unit 5 is also electrically connected to Motor 12 and Linear Driver 8, controlling Motor 12 and Linear Driver 8 based on the received signals. It is the core control component for achieving automated operation of the entire device.

[0038] Blocking Mechanism 6: Located downstream of the infrared sensor 4, the blocking mechanism 6 includes a support frame 7 spanning the conveyor belt 3, a linear actuator 8 mounted on the support frame 7, and a baffle 9 driven to rise and fall by the linear actuator 8. The linear actuator 8 can be a cylinder or an electric push rod, which drives the baffle 9 to rise and fall through its extension and retraction. A height gap is formed between the lower surface of the baffle 9 and the bearing surface of the conveyor belt 3, and this height gap is smaller than the minimum diameter of the corn to be conveyed, to ensure effective blocking of the corn. In addition, guide posts 10 are installed on both sides of the baffle 9, penetrating the support frame 7. The support frame 7 has guide holes 11 at the positions corresponding to the guide posts 10. The guide posts 10 cooperate with the guide holes 11 to provide guidance for the rising and falling of the baffle 9, ensuring the smoothness and accuracy of the rising and falling process of the baffle 9.

[0039] Working principle: When this utility model is used, the corn conveying infrared sensing stop device is based on the infrared sensor 4 and the control unit 5. Through the coordinated operation of various components, it realizes the automated control and precise stopping of corn conveying. During operation, the motor 12 starts, providing power to the conveyor belt 3, driving the conveyor belt 3 to run continuously, and conveying the corn placed on the conveyor belt along the predetermined path.

[0040] When the corn moves with the conveyor belt 3 to the detection area of ​​the infrared sensor 4, the corn blocks the infrared signal emitted by the infrared sensor 4. The photoelectric conversion element inside the infrared sensor 4 detects the change in light, converts the light signal into an electrical signal, and immediately transmits the detection signal to the control unit 5.

[0041] After receiving the corn shading signal from the infrared sensor 4, the control unit 5 quickly analyzes and processes the signal. Based on the preset control logic, the control unit 5 sends commands to the linear actuator 8 and the motor 12. The motor 12 stops working, and the linear actuator 8 starts. If the linear actuator 8 uses a cylinder, the control unit 5 controls the switching of the air circuit solenoid valve, allowing compressed air to enter the cylinder and push the piston to lower the baffle 9. If an electric push rod is used, the control unit 5 controls the motor to operate, extending the push rod through the transmission mechanism to lower the baffle 9. During the descent of the baffle 9, the guide posts 10 on both sides slide within the guide holes 11, providing stable guidance for the raising and lowering of the baffle 9, ensuring that the baffle 9 descends accurately and smoothly to the working position. Because the height gap between the lower surface of the baffle 9 and the bearing surface of the conveyor belt 3 is less than the minimum diameter of the corn to be conveyed, once the baffle 9 is in place, any corn moving in later will be blocked by the baffle 9 and unable to continue moving forward, thus stopping the corn on the conveyor belt. The baffle 9 does not contact the conveyor belt 3 to form an obstruction and will not affect the equipment.

[0042] After completing the corn blocking action, the control unit 5 can further control the operating status of the motor 12 according to actual needs, such as reducing the speed or pausing operation, to avoid energy waste or corn accumulation and compression caused by the continued operation of the conveyor belt 3. When the preset release conditions are met, such as manual operation or detection of no corn blocking signal again, the control unit 5 will send a reverse command to the linear driver 8, causing it to drive the baffle 9 to rise and reset, restoring the corn conveying channel so that corn conveying can continue.

[0043] Beneficial effects: Infrared sensor triggering and timely response: Infrared sensor 4 detects corn shading signals in real time. After receiving the signal, control unit 5 can quickly drive baffle 9 to descend, achieving precise stopping of corn conveying and avoiding delays or errors caused by manual intervention.

[0044] The control unit 5 has preset control logic to synchronously control the motor 12 to stop and the baffle 9 to descend, ensuring that the "detection-stop-blocking" action is smooth and improving the level of automation.

[0045] It features efficient blocking and protection functions, non-contact blocking that does not damage equipment. The baffle 9 blocks the corn through a height gap (smaller than the minimum diameter of the corn), without direct contact with the conveyor belt 3, thus avoiding frictional wear and extending the service life of the equipment.

[0046] Intelligent shutdown for energy saving: after corn is detected, control unit 5 synchronously controls motor 12 to stop running, avoiding energy waste caused by the conveyor belt running idle and reducing operating costs.

[0047] To prevent corn from piling up and being squeezed, baffle 9 promptly blocks subsequent corn and, in conjunction with the motor stopping, prevents damage or blockage caused by corn piling up and being squeezed, ensuring a smooth conveying process.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
