Description

Technical Field

[0001] This utility model relates to the field of adjustment mechanism technology, specifically to an air volume adjustment mechanism for a drying equipment. Background Technology

[0002] Natural drying requires a large amount of farmland or roads as drying areas, resulting in more impurities. Drying on roads can also severely disrupt traffic and cause accidents, and agricultural products are easily broken or damaged. Natural drying is also time-consuming, affecting seed quality and germination rates. Mechanized drying effectively solves these drawbacks.

[0003] Chinese utility model CN221724857U describes an airflow adjustment mechanism for a dryer. The mechanism is designed with an adjustment structure that uses a motor to drive the winding roller to rotate, thereby adjusting the position of the slider inside the air duct. This can block the airflow inside the air duct, thereby adjusting the air outlet area of ​​the air duct and achieving the adjustment function.

[0004] However, existing devices adjust the airflow by using a slider inside the duct. The duct below the slider dries the material inside, while the duct above the slider is blocked and cannot discharge air. Although this achieves the purpose of regulating airflow, the airflow is not uniform. If the drying chamber is full of material, the material at the top dries poorly. Therefore, an adjustment mechanism was designed to address the above problems and make the airflow more uniform. Utility Model Content

If the specific posture changes, the directional indications will also change accordingly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0031] Natural drying requires a large amount of farmland or roads as drying areas, resulting in more impurities. Drying on roads can also severely disrupt traffic and cause accidents, and agricultural products are easily broken or damaged. Natural drying is also time-consuming, affecting seed quality and germination rates. Mechanized drying effectively solves these drawbacks.

[0032] In related technologies, a motor drives a winding roller to rotate, thereby adjusting the position of a slider inside the duct. This blocks the airflow within the duct, thus adjusting the air outlet area and achieving the desired airflow regulation. However, existing devices adjust the airflow by using the slider's position within the duct. The duct below the slider dries the material inside, while the duct above the slider is blocked and cannot discharge air. Although this achieves the purpose of regulating airflow, the airflow is uneven. If the drying chamber is full of material, the material at the top dries poorly.

[0033] To address some of the problems in related technologies, this application provides an airflow adjustment mechanism for a drying equipment. When drying the material inside the drying chamber 11, the blower 13 is first connected to an external power source to supply warm air into the air duct 12. The warm air is blown out through the overlapping portion of the holes on the inner tube 21 and the air duct 12, thus drying the material inside the drying chamber 11. When adjusting the airflow, the threaded rod 26 is rotated, and during rotation, it connects threadedly to the extrusion block 27. The top of the extrusion block 27 is attached to the inner wall of the U-shaped plate 25, which can restrict the rotation of the extrusion block 27. Therefore, when the threaded rod 26 rotates, it drives the two extrusion blocks 27 to move closer. At the same time, they will come into contact with the pressure block 24 and squeeze the pressure block 24 to move downward. This causes the pressure block 24 to push the upright rod 22 downward, thereby driving the inner tube 21 to move downward inside the air duct 12. At the same time, the spring 23 is stretched. While moving downward, the holes on the inner tube 21 and the holes on the air duct 12 are misaligned to adjust the size of the air outlet, thereby adjusting the air volume.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] This application provides an airflow adjustment mechanism for a drying device, comprising: a drying chamber 11 with an air duct 12 inside, one end of which penetrates the inner wall of the drying chamber 11; a blower 13 disposed at one end of the air duct 12; and an adjustment assembly 2 disposed on the top of the drying chamber 11, the adjustment assembly 2 comprising: an inner tube 21 disposed inside the air duct 12; a vertical rod 22 with its bottom end penetrating the top of the drying chamber 11 and connected to the top of the inner tube 21; a spring 23 with both ends connected to the inner wall of the top of the drying chamber 11 and the top end of the inner tube 21; a pressure block 24 disposed on the top of the vertical rod 22; a U-shaped plate 25 disposed on the top of the drying chamber 11; a threaded rod 26 with one end penetrating the U-shaped plate 25 and rotatably connected to the U-shaped plate 25; and a pressing block 27 penetrated by the threaded rod 26 and threadedly connected to the threaded rod 26, the top of which is in contact with the inner wall of the U-shaped plate 25.

[0036] Specifically, blower 13 is model RB-200AS. Its working principle involves drawing in and compressing air through a high-speed rotating impeller, then heating the air with a heater, and finally blowing out a high-temperature airflow from the outlet. The specific process is as follows:

[0037] Air intake and compression: The blower impeller rotates at high speed, using an eccentrically rotating rotor to draw in and compress air. During operation, the pressure difference of the blower automatically delivers lubricating oil to the drip nozzle, dripping it into the cylinder to reduce friction and noise, while preventing backflow of gas within the cylinder.

[0038] Heating process: Compressed air is fed into the heater, usually heated by a spiral heating wire. The heat generated by the heating wire after being energized exchanges heat with the passing cold air, thereby raising the temperature of the air at the outlet.

[0039] Temperature control: The K-type thermocouple at the air outlet promptly feeds back the detected outlet air temperature to the temperature controller. The instrument monitors the actual temperature based on the set temperature and controls the heater's operating status via a solid-state relay. Furthermore, the fan can utilize airflow regulators (such as frequency converters or dampers) to adjust the airflow, thereby controlling both operating temperature and airflow.

[0040] When drying the materials inside the drying chamber 11, the blower 13 needs to be connected to an external power source to deliver warm air into the air duct 12. The warm air is blown out through the overlapping part of the holes on the inner tube 21 and the air duct 12, which can dry the materials inside the drying chamber 11. When the air volume needs to be adjusted, the threaded rod 26 can be rotated. When rotating, it will be threadedly connected to the extrusion block 27. Because the top of the extrusion block 27 is attached to the inner wall of the U-shaped plate 25, it can restrict the rotation of the extrusion block 27. So when the threaded rod 26 rotates, it drives the two extrusion blocks 27 to move closer. When they move closer, they will contact the pressure block 24 and squeeze the pressure block 24 to move downward. This causes the pressure block 24 to push the upright 22 downward, thereby driving the inner tube 21 to move downward inside the air duct 12. At the same time, the spring 23 is stretched. While moving downward, the holes on the inner tube 21 and the holes on the air duct 12 are misaligned to adjust the size of the air outlet, thereby adjusting and controlling the air volume.

[0041] In some embodiments, the spring 23 is sleeved on the outside of the upright 22.

[0042] The design of the sleeve being placed on the outside during use prevents the spring 23 from bending when it extends, thus better protecting the spring 23.

[0043] In some embodiments, the inclined surface of the pressure block 24 has the same inclination angle as the inclined surface of the compression block 27.

[0044] The design, with the same tilt angle during use, allows for a better fit upon contact, thus reducing chafing during compression.

[0045] In some embodiments, the adjustment assembly 2 further includes a handle 28 disposed at one end of the threaded rod 26.

[0046] The handle 28 is designed for easy gripping, thus providing better control over the rotation of the threaded rod 26.

[0047] In some embodiments, the adjustment component 2 further includes a pipe body 29 disposed at the top of the air duct 12.

[0048] When in use, the design of the tube body 29 can enclose the spring 23, preventing it from coming into contact with the material inside the drying chamber 11, thus affecting the extension and contraction of the spring 23.

[0049] In some embodiments, a positioning component 3 is provided on one side of the U-shaped plate 25. The positioning component 3 includes: a through groove 31 opened on the outside of the threaded rod 26; an annular body 32 sleeved on the outside of the threaded rod 26; a crossbar 33 slidably disposed on the inside of the through groove 31, and both ends connected to the inner sidewall of the annular body 32; a positioning hole 34 opened on the outer sidewall of the U-shaped plate 25; and an insert rod 35 disposed on one side of the annular body 32, with one end inserted into the interior of the positioning hole 34.

[0050] When in use, after adjustment, the threaded rod 26 needs to be restricted to prevent it from rotating. Simply push the ring 32 to slide on the threaded rod 26. At the same time, the ring 32 drives the crossbar 33 to slide inside the through groove 31, so that the insert rod 35 on one side of the ring 32 is inserted into the positioning hole 34 to restrict the threaded rod 26.

[0051] In some embodiments, the positioning component 3 further includes a baffle 36 disposed at one end of the threaded rod 26.

[0052] The design of the baffle 36 during use can prevent the ring 32 from detaching from one end of the threaded rod 26.

[0053] In some embodiments, the positioning component 3 further includes: a magnetic ring 37 disposed on both sides of the ring body 32; and a magnetic ring 38 disposed on one side of the baffle 36 and the U-shaped plate 25.

[0054] When in use, the magnetic attraction between magnetic ring 37 and magnetic ring 38 allows ring 32 to be stably attached to baffle 36 and U-shaped plate 25, thus stabilizing the position of ring 32.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
