Description

Technical Field

[0001] This application relates to the technical field of air volume regulation, and in particular to an air volume regulation and replenishment device for a grain drying equipment. Background Technology

[0002] Currently, in the agricultural production process, airflow regulation during grain drying is a key step in ensuring grain storage quality and reducing post-harvest losses.

[0003] In terms of air volume regulation, traditional devices usually use fixed air outlets or simple baffles to regulate air volume, which makes it difficult to achieve precise control and cannot adapt to the drying needs of different grains, resulting in inconsistent drying quality. In terms of air volume replenishment, traditional devices lack an active replenishment mechanism. Once the air volume is insufficient due to equipment operation or changes in the external environment, the drying process will be severely affected or even interrupted.

[0004] Regarding the aforementioned technologies, the applicant believes that they suffer from a lack of adaptive adjustment capabilities. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides an airflow regulation and replenishment device for a grain drying equipment.

[0006] This application provides an airflow regulation and replenishment device for a grain drying equipment, which adopts the following technical solution:

[0007] An airflow regulation and replenishment device for a grain drying equipment includes a housing, an airflow regulation mechanism, a drive mechanism, an airflow replenishment mechanism, and a filter assembly. The airflow regulation mechanism is installed inside the housing and is fixedly connected to the housing. The drive mechanism is fixedly connected to the airflow regulation mechanism and is also fixedly installed on the housing. The airflow replenishment mechanism is installed inside the housing and is fixedly connected to the housing. The filter assembly is installed inside the housing and is detachably connected to the housing.

[0008] By adopting the above technical solutions, the air volume regulating mechanism can accurately control the amount of air entering the drying equipment, ensuring that the grain drying process is efficient and uniform, and avoiding over-drying or under-drying. The drive mechanism provides power to the air volume regulating mechanism to drive its operation. The air volume replenishment mechanism replenishes the air volume in a timely manner when the air volume inside the equipment is insufficient, ensuring that the air volume required for the drying process is met. The filter component filters dust and impurities in the outside air, ensuring the clean operation of the equipment.

[0009] Preferably, the air volume regulating mechanism includes multiple louvered plates and a louvered frame, with the multiple louvered plates arranged in parallel inside the louvered frame, and the louvered plates and the louvered frame being rotatably connected, and the louvered frame being fixedly installed on the duct wall inside the air inlet.

[0010] By adopting the above technical solution, multiple louvered panels are arranged in parallel within the louvered frame and can be rotated under the control of the drive mechanism. By changing the rotation angle of the louvered panels, the size of the ventilation opening can be adjusted. When a large air volume is required for rapid drying, the louvered panels can be rotated to a larger opening angle. In the later stages of drying or when processing grains that are sensitive to air volume, the opening angle of the louvered panels can be reduced, thereby precisely adjusting the air volume.

[0011] Preferably, the drive mechanism includes a drive motor and an output shaft. The drive motor is mounted on the outer wall of the housing. An output shaft is installed at the output end of the drive motor and is fixedly connected to the drive motor. The other end of the output shaft has a hole on the outer wall of the housing, through which the other end of the output shaft is inserted and fixedly connected to the air volume adjustment mechanism.

[0012] Preferably, a shock-absorbing plate is provided at the connection between the drive motor and the outer wall of the housing. The two ends of the shock-absorbing plate are fixedly connected to the drive motor and the outer wall of the housing, respectively. A shock-absorbing spring is provided inside the shock-absorbing plate, and the shock-absorbing spring is fixedly connected to the shock-absorbing plate.

[0013] By adopting the above technical solution, the drive mechanism consists of a drive motor and an output shaft. When the drive motor is working, it drives the output shaft to rotate, which in turn drives the louvers in the air volume adjustment mechanism to rotate, thereby achieving air volume adjustment. In addition, the shock-absorbing plate and shock-absorbing spring installed at the connection between the drive motor and the outer wall of the housing can effectively reduce the vibration and noise generated during motor operation, ensure the stability of the drive mechanism operation, extend the service life of the equipment, and also reduce interference with the working environment.

[0014] Preferably, the air volume replenishment mechanism includes a housing and a fan. The housing is installed at the air inlet, and an inspection port is provided at the corresponding box of the housing. A support plate extends from the inspection port. The housing and the support plate are detachably connected. A fan is provided inside the housing, with the fan outlet aligned with the air inlet, and the fan is fixedly connected to the housing.

[0015] By adopting the above technical solution, the function of the air volume replenishment mechanism is to replenish the air volume in a timely manner when the air volume inside the equipment is insufficient during the drying process, so as to maintain the stability of the drying process. When the air volume inside the equipment is detected to be lower than the set value, the fan starts to draw in the outside air and replenish the drying equipment. The design of the inspection port facilitates the maintenance and repair of the fan, ensuring that the air volume replenishment mechanism can work continuously and reliably.

[0016] Preferably, the filter assembly includes a filter screen and a slide rail. The slide rail is installed on the air inlet channel and is fixedly connected to the air inlet channel. The filter screen is installed on the slide rail and is slidably connected to the slide rail. The housing corresponding to the filter screen is also provided with an opening and a cover plate at the opening. The cover plate is hinged to the housing.

[0017] By adopting the above technical solution, the filter screen is set at the bottom near the air inlet channel to prevent grains from entering the air inlet channel when it is poured in, and to prevent the grains from affecting the normal operation of the air supply device. After the filter screen has been used for a period of time, it can be pulled out through the slide rail and taken out from the opening of the box for cleaning or replacement. The operation is convenient and quick.

[0018] Preferably, the housing at the air inlet channel is a transparent housing, and an opening is provided on one side of the transparent housing. A cleaning brush is inserted into the opening, the cleaning brush is attached to the inner wall of the housing, and the handle of the cleaning brush extends from the opening to the outside of the housing.

[0019] By adopting the above technical solution, the transparent enclosure design at the air inlet channel allows operators to intuitively observe the internal air intake and the status of the filter components. Problems such as whether the air intake is smooth or whether the filter is clogged can be detected in a timely manner without disassembling the enclosure, thus improving the convenience and timeliness of equipment operation monitoring.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The air volume regulating mechanism precisely controls the amount of air entering the drying equipment, ensuring efficient and uniform grain drying and avoiding over-drying or under-drying. The drive mechanism provides power to the air volume regulating mechanism to drive its operation. The air volume replenishment mechanism replenishes the air volume in a timely manner when the air volume inside the equipment is insufficient, ensuring that the air volume required for the drying process is met. The filter component filters dust and impurities from the outside air, ensuring the clean operation of the equipment.

[0022] 2. The function of the air volume replenishment mechanism is to replenish the air volume in a timely manner when the air volume inside the equipment is insufficient during the drying process, so as to maintain the stability of the drying process. When the air volume inside the equipment is detected to be lower than the set value, the fan starts to draw in the outside air and replenish the drying equipment. The design of the inspection port facilitates the maintenance and repair of the fan, ensuring that the air volume replenishment mechanism can work continuously and reliably.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses an airflow regulation and replenishment device for a grain drying equipment. (Refer to...) Figure 1-3 The equipment includes a housing 1, an airflow regulating mechanism 2, a drive mechanism 3, an airflow supply mechanism 4, and a filter assembly 5. The airflow regulating mechanism 2 is securely installed inside the housing 1 and fixedly connected to it. It consists of a louvered frame 21 and multiple louvered plates 22. The louvered frame 21 is firmly fixed to the duct wall inside the air inlet. The multiple louvered plates 22 are arranged in parallel and can rotate flexibly. By changing their angle, the airflow entering the drying equipment can be precisely controlled. The drive mechanism 3 is fixedly installed on the housing 1 and tightly connected to the airflow regulating mechanism 2. The drive motor 31 is installed on the outer wall of the housing 1. Its output shaft 32 passes through the corresponding hole on the housing 1 and is fixedly connected to the louvered plate rotating shaft of the airflow regulating mechanism 2. When the drive motor 31 runs, it drives the output shaft 32 to rotate, thereby driving the louvered plates 22 to rotate flexibly. A shock-absorbing plate 6 is provided at the connection between the drive motor 31 and the outer wall of the housing 1. The internal shock-absorbing spring 61 effectively reduces the vibration and noise generated during motor operation, making the drive mechanism 3 run more smoothly and extending the service life of the equipment.

[0030] The air supply mechanism 4 is installed inside the housing 1 and is fixedly connected to the housing 1. When additional air is needed, the fan 42 inside the housing 41 starts quickly and supplies air to the drying equipment through the air inlet channel, maintaining the stable operation of the drying process. The housing 41 is detachably connected to the support plate extending from the inspection port of the housing, facilitating maintenance and repair of the fan 42 by personnel, ensuring that the air supply function is always online. The filter assembly 5 is also installed inside the housing 1 and is detachably connected to the housing 1. The filter screen 51 is installed on the slide rail 52 at the bottom of the air inlet channel, which can effectively intercept air from the outside air. Dust, impurities, and particles that may enter the channel when grains are poured in are removed to prevent them from affecting the normal operation of the equipment. After the filter screen 51 has been used for a period of time, it can be easily pulled out through the slide rail 52 and taken out from the opening of the box 1 for cleaning or replacement. The part of the box 1 at the air inlet channel is made of transparent material, so the operator can directly observe the internal air intake and the status of the filter component 5 without disassembling the box 1. The cleaning brush 7 inserted at the opening seam allows the operator to pull the handle to drive the cleaning brush to wipe the inner wall of the box 1, keep the air duct unobstructed, and provide a clear view for observing the air duct.

[0031] The working principle of the air volume adjustment and replenishment device for a grain drying equipment in this application is as follows: When the equipment is started, the drive motor 31 installed on the outer wall of the housing 1 is powered on and rotates, and its output shaft 32 rotates accordingly. Since the output shaft 32 is fixedly connected to the rotating shaft of the louver 22 in the air volume adjustment mechanism 2, it drives the louver 22 to rotate within the louver frame 21. The operator can set the speed and rotation angle of the drive motor 31 through the control system according to the different needs of the grain type and drying stage, thereby precisely adjusting the opening degree of the louver 22. For example, when a large air volume is needed to quickly remove the moisture from the grain in the early stage of drying, the louver 22 will rotate to a larger opening angle to increase the cross-sectional area of ​​the ventilation opening and allow more air to enter the drying equipment. In the later stage of drying, in order to prevent the grain from being over-dried, the louver 22 will reduce the opening angle and reduce the air volume to achieve uniform drying.

[0032] While the air volume regulating mechanism 2 controls the main air volume, the air volume replenishment mechanism 4 is installed at the air inlet. When the air volume is insufficient, the fan 42 quickly starts, drawing in air from the outside and replenishing it into the drying equipment through the air inlet, ensuring a stable air volume required for the drying process and preventing a decrease in drying efficiency or uneven drying of grains due to insufficient air volume. When the air volume returns to normal, the fan 42 stops working. If the fan 42 malfunctions or requires maintenance, the staff can quickly disassemble the housing 41 for inspection or replacement, ensuring the reliability of the air volume replenishment function. The filter screen 51 installed on the slide rail 52 at the bottom of the air inlet channel can effectively intercept impurities in the outside air and particles that may enter the channel when the grains are poured in. As the air intake increases, when the filter screen 51 traps a lot of impurities and affects the ventilation effect, the operator can pull the filter screen 51 to pull it out from the opening of the box 1 along the slide rail 52 to clean or replace the filter screen 51. The operation is simple and convenient, ensuring that the air intake channel is always unobstructed and preventing impurities from entering the equipment and affecting the drying effect or damaging other components. Through the transparent box 1 at the air intake channel, the operator can intuitively observe whether the internal air intake is smooth and whether the filter screen 51 is blocked. If dust or grain debris is found on the inner wall of the box 1, the operator only needs to pull the handle of the cleaning brush 7 located on the outside of the box 1. The cleaning brush 7 will move along the inner wall of the box 1 to remove debris, keep the air duct clean, and further ensure the efficient operation of the device.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
