Description

Technical Field

[0001] This utility model relates to the field of automatic adjustment device technology, and in particular to an automatic adjustment device for a multifunctional agricultural dryer. Background Technology

[0002] As a fundamental industry of the national economy, agriculture's post-harvest drying process directly affects the quality and storage period of agricultural products. With the development of modern agriculture towards large-scale and intelligent operations, traditional single-function agricultural dryers can no longer meet the drying needs of diverse agricultural products such as grains, fruits and vegetables, and cash crops. Multifunctional agricultural dryers are widely used because they can adapt to different materials and adjust drying parameters. Against this backdrop, automatic adjustment devices, as the core component for realizing the intelligent and precise operation of dryers, have become a key focus of industry attention in terms of their technological development.

[0003] The automatic adjustment device for multifunctional agricultural dryers refers to a mechatronic system that integrates sensing, control, and execution mechanisms to monitor and dynamically adjust key parameters such as temperature, humidity, and airflow during the drying process in real time. Early adjustment devices relied on manually preset parameters, resulting in low adjustment accuracy and an inability to adapt to changes in material characteristics, often leading to uneven drying and energy waste. To solve these problems, existing technologies have been upgraded through mechanical structure optimization, employing a combination of cams and linkages. Through precise design of the cam profile curve, the damper opening and the deformation displacement of the temperature sensor are linked to achieve mechanical feedback adjustment of temperature. However, this approach is complex and has high maintenance costs. The precision fit of the linkages is prone to wear, leading to decreased adjustment accuracy after long-term operation. Furthermore, disassembly and maintenance are difficult, and the adaptive capability is limited, resulting in low practicality. Utility Model Content

[0006] The temperature regulating mechanism includes a guide plate, the front and rear sides of which are rotatably connected to the inner wall of the generating cylinder. A long column is fixedly connected to the middle of the guide plate, and an elongated plate is fixedly connected to the top of the long column. A fan is fixedly connected to the inner wall of the generating cylinder, a heating component is provided at the top of the generating cylinder, and a rotating component is provided at the top of the elongated plate.

[0007] As a further description of the above technical solution:

[0009] As a further description of the above technical solution:

[0010] The heating assembly includes a connecting plate, the front and rear sides of which are fixedly connected to the inner wall of the generating cylinder, and a mounting frame is fixedly connected to the bottom of the connecting plate. Multiple heating tubes are fixedly connected to the inner wall of the mounting frame.

[0011] As a further description of the above technical solution:

[0012] The rotating assembly includes a lever, the bottom of which is fixedly connected to the top of an elongated plate, a mounting base rotatably connected to the middle of the lever, a U-shaped plate fixedly connected to the left side of the lever, and a metal component provided on the inner wall of the U-shaped plate.

[0013] As a further description of the above technical solution:

[0014] The metal assembly includes a first metal sheet, the top of which is rotatably connected to the inner wall of the U-shaped plate, and a second metal sheet is fixedly connected to the bottom of the first metal sheet.

[0015] As a further description of the above technical solution:

[0016] The connecting component includes multiple sliding blocks, each of which has a moisture-absorbing column fixedly connected to its left and right sides. A connecting block is fixedly connected to the top of each sliding block, and a sliding component is provided on the front side of each connecting block.

[0017] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, air enters from the right guide plate, the fan is turned on, and air exits from the left guide plate, the heating tube is turned on, thus heating the air. When the temperature of the inner wall of the generating cylinder rises, the first metal sheet and the second metal sheet are of the same length. The first metal sheet has a smaller coefficient of thermal expansion, while the second metal sheet has a larger coefficient of thermal expansion. Therefore, the second metal sheet tilts upward. According to the lever principle, the long plate drives the guide plate and the long column to move downward, increasing the distance between the guide plates and accelerating the drying speed. When the temperature drops, the first metal sheet and the second metal sheet return to their original shape, reducing the distance between the guide plates and realizing automatic temperature regulation, thus enhancing practicality.

[0023] 2. In this utility model, the moisture-absorbing column is a moisture-absorbing material. When the moisture-absorbing column absorbs too much moisture, it expands and elongates, causing multiple sliding blocks to move in opposite directions. This drives the sliding square blocks on both sides to slide along the slide rail, increasing the opening of the slide rail and accelerating the release of moisture. When the moisture content decreases, the moisture-absorbing column returns to its original length, causing the slide rail to cover the slide groove, thus achieving automatic humidity regulation and improving flexibility.
