Description

Technical Field

[0001] The utility model relates to the technical field of ventilation of an oat de-awning machine, and more particularly to a ventilation mechanism of an oat de-awning machine. Background Art

[0002] Oats, an annual herbaceous plant of the genus Avena in the grass family, are a nutritious cereal. Their grains are typically elongated and slender, rich in dietary fiber, protein, vitamins, and minerals. They offer numerous health benefits, including lowering cholesterol, controlling blood sugar, and improving bowel function. They are commonly used in food processing, such as making oatmeal and oatmeal porridge.

[0003] The ventilation mechanism of the oat de-awning machine is an important component of the machine. Its main function is to achieve air circulation inside the machine through reasonable design during the de-awning process. The principle of the ventilation mechanism is to use the power of the airflow to blow away the oat shells and impurities and discharge them out of the machine, thereby achieving the purpose of effectively separating the oat kernels and shells. The ventilation mechanism plays a very important role in the oat de-awning machine and can improve the de-awning efficiency and quality.

[0004] When the ventilation mechanism of the existing oat de-awning machine ventilates the inside of the oat de-awning machine, dust and oat shells are discharged to the outside along with the ventilation airflow. However, in actual use scenarios, due to the strong force of the airflow, these oat shells and dust will be blown up, which not only significantly increases the difficulty of collection, but also causes great pollution to the working environment, bringing many inconveniences to actual use;

[0005] Existing ventilation systems typically rely on fans for ventilation. However, during startup, these fans inevitably vibrate, causing significant noise. This vibration and noise not only affects the operator's work experience but can also cause noise pollution to the surrounding environment. Furthermore, during exhaust, the rapid passage of air also generates significant airflow noise. These two noises combined create a strong noise disturbance, severely affecting the comfort of the working environment and causing significant distress to users.

[0006] In view of this, we propose a ventilation mechanism for an oat deawning machine. Utility Model Content

[0017] 3. Beneficial effects

[0018] Compared with the existing technology, the advantages of the present invention are: during the use of the oat de-awning machine for ventilation, the operation of the ventilator can drive the oat shells and impurities into the soundproof cover under the traction of the ventilator. Then, the larger oat shells are intercepted by filter plate one, and the finer dust is further intercepted by filter plate two. During the interception process, the vibration generated by the ultrasonic vibrator can be used to shake off the impurities attached to filter plate one and filter plate two, and then discharged through the discharge hopper. Since the airflow passes through filter plate one and filter plate two during the process of intercepting impurities, and is then discharged by multiple silencer exhaust pipes one and two, this design can effectively reduce the phenomenon of impurities and oat shells being lifted up by the airflow, and filter plate one and filter plate two can also vibrate and clean themselves, significantly reducing the risk of clogging.

[0019] When the ventilator is working and generating vibrations, the buffer springs arranged behind the buffer plate and the buffer rubber pads arranged in front of the buffer plate, in conjunction with the buffer rubber strips, can comprehensively improve the buffering performance of the ventilation structure after installation. This can greatly reduce the noise caused by hard collisions. In addition, the airflow can be evenly discharged through multiple silencer exhaust ducts 1 and 2, thereby reducing the pressure difference inside the soundproof cover and avoiding uneven pressure caused by poor local exhaust, thereby reducing the noise and vibration during machine operation and significantly improving the stability and reliability of the machine.

[0029] In some embodiments, the soundproof cover 100 may be provided with an interlayer inside, and the interlayer may be filled with sound insulation cotton to reduce the diffusion of noise.

[0030] A discharge hopper 110 is provided at the bottom of the soundproof cover 100, a ventilator 120 is provided on the front outer wall of the soundproof cover 100, a ventilation hood 130 is provided on the front outer wall of the ventilator 120, connecting plates 150 are provided on the outer walls on both sides of the soundproof cover 100, a silencer exhaust duct 140 is provided on the rear outer wall of the soundproof cover 100, an ultrasonic generator 160 is provided on the top of the soundproof cover 100, a clamping frame 1 200 and a clamping frame 2 230 are provided on the inner wall of the soundproof cover 100, and an installation buffer assembly is also provided on the top of the soundproof cover 100, and the installation buffer assembly includes a fixing block 300.

[0031] Specifically, multiple connecting plates 150 are provided with side walls with silencer exhaust duct 2 151, and the structure of silencer exhaust duct 2 151 is the same as that of silencer exhaust duct 1 140. The inner walls of multiple silencer exhaust duct 1 140 and silencer exhaust duct 2 151 are provided with sound insulation cotton and limited by metal mesh barrels to reduce the noise during exhaust. Silencer exhaust duct 1 140 and silencer exhaust duct 2 151 both belong to the existing technology.

[0032] Furthermore, a filter plate 210 is clamped inside the clamping frame 1 200 , and an ultrasonic vibration rod 220 electrically connected to the ultrasonic generator 160 is provided in the inner cavity of the clamping frame 1 200 .

[0033] In some embodiments: the ultrasonic vibrator 220 is a vibrating device, which is usually composed of a vibrating head, a vibrating core and a shell. The vibrating head is the key part of the vibration. It can convert electrical energy into mechanical vibration to generate ultrasonic vibration. The vibrating core is the core part of the vibrating head and is responsible for transmitting the vibration force to the vibrating head. The shell is used to protect the vibrating head and the vibrating core, and also plays a role of fixing and supporting. The ultrasonic generator 160 is the key part of controlling the operation of the ultrasonic vibrator 220, which usually includes components such as an oscillation circuit, a power amplifier, and a frequency controller. The ultrasonic generator 160 converts electrical energy into the driving force required for ultrasonic vibration by generating a high-frequency electrical signal, and controls its vibration frequency and amplitude. The above are all existing technologies, which are convenient for vibrating and cleaning impurities on the outer walls of filter plate 1 210 and filter plate 2 240 to reduce the risk of clogging.

[0034] Furthermore, a filter plate 240 is clamped inside the second clamping frame 230.

The diameter of the filter plate 240 is smaller than that of the filter plate 1 210, which is convenient for intercepting oat hulls and dust.

[0035] Furthermore, a buffer spring 310 is provided on the inner wall of the fixing block 300 , and a buffer plate 320 is connected to the ends of the plurality of buffer springs 310 .

[0036] It is worth noting that the outer wall of the buffer plate 320 is provided with a buffer rubber strip 330, and the side wall of the buffer plate 320 is also provided with a buffer rubber pad 340 and a connecting block 350, which is convenient for buffering when the ventilator 120 vibrates and reducing the spread of its noise.

[0037] It is worth noting that the end of the connecting block 350 is connected to a mounting plate 360 , and the outer wall of the mounting plate 360 is provided with mounting holes to facilitate the installation of the ventilation structure on the outer wall of the oat deawning machine.

[0038] In some embodiments: the device is powered by an external conventional power supply, and the device can be controlled by an external controller, all of which belong to the prior art.

[0039] In addition, the circuits, electronic components and modules involved in the present invention are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to the internal structure and methods.

[0040] Working principle: During the ventilation operation of the oat de-awning machine, the operation of the ventilator 120 can drive the oat shells and impurities into the interior of the soundproof cover 100 under the traction of the ventilator. Afterwards, the filter plate 1 210 is used to intercept the larger oat shells, and the finer dust will be further intercepted by the filter plate 2 230. During the interception process, the vibration generated by the ultrasonic vibration rod 220 can be used to shake off the impurities attached to the filter plate 1 210 and the filter plate 2 230, and then discharged through the discharge hopper 110. In the process of intercepting impurities, the airflow will pass through the filter plate 1 210 and the filter plate 2 240, and then be discharged by multiple silencer exhaust pipes 1 140 and silencer exhaust pipes 2 151. This design can effectively reduce the phenomenon of impurities and oat shells being lifted up by the airflow, and the filter plate 1 and the filter plate 2 can also vibrate and clean themselves. Clean, significantly reducing the risk of its blockage, and when the ventilator 120 is working and generating vibrations, the buffer spring 310 arranged behind the buffer plate 320 and the buffer rubber pad 340 arranged in front of it, in conjunction with the buffer rubber strip 330, can comprehensively improve the buffering performance of the ventilation structure after installation, thereby greatly reducing the noise caused by hard collisions, and the airflow can be evenly discharged through multiple silencer exhaust pipes 1 140 and silencer exhaust pipes 2 151, thereby reducing the pressure difference inside the soundproof cover 100, avoiding uneven pressure caused by poor local exhaust, and thus reducing the noise and vibration of the machine during operation, and significantly improving the stability and reliability of the machine.
