Description

Technical Field

[0001] This utility model mainly relates to the field of straw briquetting machine technology, specifically to the buffer feeding structure of the automatic feeding device of the briquetting machine. Background Technology

[0002] In the field of straw resource utilization, straw briquetting machines are key equipment for agricultural waste treatment. By compressing straw into shape, they enable efficient storage and combustion applications. The automatic feeding device of this equipment directly affects the briquetting efficiency and quality. Stable and uniform material conveying is an important prerequisite for ensuring the continuous operation of the briquetting machine.

[0003] During the actual implementation process, the inventors discovered the following defects:

[0004] Existing feeding devices generally suffer from technical bottlenecks: on the one hand, the long and easily tangled nature of straw fibers leads to a lack of effective anti-blocking measures at the connection between the conveyor belt and the hopper, resulting in frequent material accumulation and blockage problems that require frequent manual intervention; on the other hand, traditional devices mostly use fixed material blocking structures, which cannot adjust the feeding amount in real time according to the material status, easily causing fluctuations in the feeding of the briquetting machine, leading to equipment overload or unstable molding quality; frequent start-ups and shutdowns caused by blockages and uneven feeding exacerbate the wear and tear on motors and transmission components, significantly reducing the service life of the equipment.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0031] See attached document Figure 1-3 The buffer feeding structure of the automatic feeding device for the briquetting machine includes a conveyor belt 1 and a hopper 9. The conveyor belt 1 is provided with directional swing arms 2 on both sides, and a drive shaft 3 is provided between the two directional swing arms 2. The drive shaft is provided with a material blocking component 4 and multiple anti-blocking components 5. The material blocking component 4 and multiple anti-blocking components 5 are all arranged around the drive shaft 3. A drive component 6 is provided on one side of the directional swing arm 2, and a sensor component 7 is provided on the side of the conveyor belt 1 and the corresponding side of the material blocking component 4.

[0032] The drive assembly 6 includes a first rotary motor 601, a second rotary motor 602, and a motor cover 603. The first rotary motor 601 and the second rotary motor 602 are embedded in the motor cover 603, which protects the motors and prevents dust and straw from entering the motor and affecting its normal operation. The drive end of the first rotary motor 601 is connected to the directional swing arm 2 and is located on the side of the conveyor belt 1. The drive end of the second rotary motor 602 is connected to the drive shaft 3. The directional swing arm 2 rotates through the first rotary motor 601, thereby adjusting the position of the drive shaft 3, the material blocking assembly 4, and the anti-blocking assembly 5 relative to the conveyor belt 1. After adjustment, the other end of the drive shaft 3 is supported by the bearing seat 8, improving the transmission accuracy and stability of the drive shaft 3. The second rotary motor 602 drives the drive shaft 3 to rotate, enabling the material blocking assembly 4 and the anti-blocking assembly 5 to rotate around the drive shaft 3, achieving a continuous, uniform, and stable feeding of straw.

[0033] Multiple anti-blocking components 5 are fixedly connected to the drive shaft 3. The anti-blocking components 5 include multiple equally spaced claws 501. The multiple claws 501 rotate with the drive shaft 3. During the rotation, they act on the straw on the conveyor belt 1 in sequence to break up the piled straw and spread it evenly on the conveyor belt 1 to prevent clogging of the discharge port.

[0034] The baffle assembly 4 includes a baffle plate 401. The inner side of the baffle plate 401 is fixedly connected to the drive shaft 3 through multiple connecting rods 402. The baffle plate 401 is arc-shaped. After rotating to a certain angle with the drive shaft 3, the lower end abuts against the conveyor belt 1. Its function is to block the continued conveying of straw and control the straw flow and conveying speed. By adjusting the distance between the baffle plate 401 and the conveyor belt 1, precise control of the straw flow can be achieved.

[0035] The sensor assembly 7 is a through-beam infrared sensor, consisting of a transmitter and a receiver, which are respectively set on the side of the conveyor belt 1 and the side of the baffle assembly 4. When the baffle assembly 4 rotates to a set angle, the sensor recognizes it and the drive motor 602 stops rotating. The baffle stop time is set according to the conveying needs. The sensor assembly 7 is also equipped with a corresponding drive shaft 3 on one side.

[0036] The conveyor belt 1 includes a conveying section and a buffer section. The hopper 9 is located at the end of the buffer section. The buffer feeding mechanism is set between the conveying section and the buffer section to realize quantitative conveying and prevent straw blockage, thereby obtaining a continuous, uniform and stable straw feeding amount.

[0037] Implementation Method 1: Continuous Dispersion Operation Mode

[0038] Initial state calibration: Start the rotary motor 601 in the drive assembly 6, and adjust the drive shaft 3 downward through the directional swing arm 2 so that the distance between the bottom surface of the baffle plate 401 and the upper surface of the conveyor belt 1 is ≤30mm (set according to the average length of straw), so that the tip of the claw 501 of the anti-blocking assembly 5 is close to the surface of the conveyor belt but does not contact it.

[0039] Continuous drive of the drive shaft: Turn on the rotary motor 602 to control the drive shaft 3 to rotate clockwise at a constant speed of 20-30 r / min, which drives the claw 501 of the anti-blocking component 5 to continuously sweep across the surface of the conveyor belt 1.

[0040] Material blocking function disabled: Maintain the initial angle between the material blocking plate 401 and the drive shaft 3 (parallel to the direction of conveyor belt operation), so that the material blocking plate 401 only rotates with the drive shaft, ensuring that the material blocking plate does not contact the material;

[0041] Continuous breaking up operation: When the conveyor belt 1 is conveying straw, the claw 501 continuously breaks up the accumulated straw layer into single fibers or small bundles, maintaining the stable position of the directional swing arm 2 until the feeding is finished.

[0042] Implementation Method 2: Intermittent Anti-clogging-Material Retention Cycle Mode

[0043] Anti-blocking component pre-start: Set the rotation speed of rotary motor 602 to 15-20 r / min, drive the claw 501 of anti-blocking component 5 to rotate counterclockwise, pre-disperse the straw in the buffer section of conveyor belt 1, and the running time is preset to 30-60 seconds;

[0044] Material blocking component angle adjustment: After the anti-blocking operation is completed, start the rotary motor 601, and lift the drive shaft 3 upward by 10-20mm through the directional swing arm 2. At the same time, drive the material blocking plate 401 to rotate clockwise around the drive shaft 3 (forming an angle with the running direction of the conveyor belt), so that the bottom surface of the material blocking plate 401 contacts the surface of the conveyor belt. After the angle is rotated to the correct position, it is identified by the sensor component 7.

[0045] Blocking and stopping control: Rotary motor 2 602 switches to intermittent mode: When the baffle plate 401 blocks the straw, the drive shaft 3 stops rotating. The stopping time is preset to 5-10 seconds by the control system, and then the rotary motor 2 602 is triggered to restart.

[0046] Cyclic operation: After a single blocking pause is completed, the drive shaft 3 rotates in the opposite direction to reset the baffle plate 401 angle, and enters the next anti-blocking and dispersing stage. This cycle of "anti-blocking and dispersing for 30-60 seconds and material blocking pause for 5-10 seconds" is performed alternately until the feeding rhythm of the briquetting machine is met.

[0047] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
