Technical Field

[0001] This utility model belongs to the technical field of insect and mold extermination machines, and in particular, it is a soundproof enclosure device for the vibration transmission system of an insect and mold extermination machine. Background Technology

[0002] Insect and mold control machines are specialized equipment that utilize physical methods (such as microwaves, ozone, ultraviolet light, and high temperatures) or chemical methods with minimal impact on food safety to continuously and industrially kill and sterilize bulk materials such as grains, medicinal herbs, tea, and feed. As materials pass through this channel during transport, insect eggs, larvae, adult insects, as well as harmful organisms such as mold and bacteria, are efficiently killed.

[0003] The vibration transmission system is its core component, used to uniformly and continuously transport the material to be treated through the disinfection area. The vibration transmission system mainly includes a vibration motor. When the vibration motor is working, it will generate strong mechanical vibration and noise, which will not only cause serious noise pollution, affecting the physical and mental health of operators and the working environment, but the vibration generated may also be transmitted to the equipment frame and the surrounding environment, affecting the stability and life of the equipment.

[0004] The purpose of this invention is to provide a soundproof enclosure device for a vibration transmission system of an insect and mold exterminator, in order to solve the problems mentioned in the background art. Utility Model Content

The sound insulation cover is U-shaped, and side plate sound insulation layers are provided on both sides of the sound insulation cover. A top plate sound absorption layer is provided on the upper inner surface of the sound insulation cover. Each set of side plate sound insulation layers comprises plate-shaped centrifugal glass wool, galvanized steel plate, and perforated protective panel, which are arranged sequentially from the inside to the outside. Inside the side panels of the soundproof enclosure, the plate-shaped centrifugal glass wool and galvanized steel plate absorb the vibrations generated by the insect and mold extermination machine body; the top plate sound-absorbing layer includes a damping rubber plate and a porous rock wool plate. The porous rock wool plate has several honeycomb-shaped grooves on its outer side to increase the area for noise absorption. The damping rubber plate and the porous rock wool plate are sequentially arranged on the top surface inside the soundproof enclosure. An air gap is provided between the porous rock wool plate and the damping rubber plate. The air gap is in a semi-vacuum state inside to absorb low-frequency vibrations.

[0015] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0016] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0017] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0018] Please see Figures 1 to 5 As shown, a soundproof enclosure device for a vibration transmission system of a pest control machine includes a pest control machine body 1. The pest control machine body 1 is an existing device, and its working principle will not be described in detail here. A feed inlet 5 is provided on the outside of the soundproof cover 3, and a discharge outlet 2 is provided on one side of the pest control machine body 1. Telescopic cylinders 4 are symmetrically arranged on the outside of the soundproof cover 3. The telescopic cylinders 4 are existing technology, and their working principle and control method are well known to those skilled in the art, so they will not be described in detail here. A connecting plate 11 is provided at the telescopic end of a single telescopic cylinder 4. Two sets of springs 12 are provided on the side of the connecting plate 11 facing the pest control machine body 1. The ends of the springs 12 are connected to a limit plate 13.

[0019] After the insect and mold exterminator body 1 stops working, it will still vibrate due to its own inertia and other reasons. At this time, the telescopic cylinders 4 on both sides of the soundproof cover 2 are activated. The telescopic cylinders 4 push the connecting plate 11 and then drive the limiting plate 13 to move forward, thereby resisting the insect and mold exterminator body 1 and preventing it from continuing to vibrate and make noise.

[0020] The soundproof cover 3 is installed on the top of the insect and mold extermination machine body 1. The soundproof cover 3 is U-shaped, and both sides of the soundproof cover 3 are provided with side plate sound insulation layers. Each set of side plate sound insulation layers includes plate-shaped centrifugal glass wool 8, galvanized steel plate 7 and perforated protective panel 6. The plate-shaped centrifugal glass wool 8, galvanized steel plate 7 and perforated protective panel 6 are arranged in sequence from the inside to the outside of the side plate of the soundproof cover 3. The plate-shaped centrifugal glass wool 8 and galvanized steel plate 7 absorb the noise and vibration generated by the insect and mold extermination machine body 1. The perforated protective panel 6 is fitted on the outside of the centrifugal glass wool and galvanized steel plate 7. The perforated protective panel 6 is made of aluminum alloy. Several holes and slots for noise to pass through are opened on the outside of the perforated protective panel 6. The perforated protective panel 6 is fixed to the side plate of the soundproof cover 3 by bolts or buckles.

[0021] The plate-shaped centrifugal glass wool 8 is mechanically fixed to form a firm and uniform cover. The high density of the galvanized steel plate 7 provides good sound insulation and can suppress the vibration and resonance of the side panels of the soundproof cover 3, preventing the side panels from becoming secondary noise radiators. The perforated protective panel 6 has holes and grooves on its surface to ensure that sound waves can smoothly enter the sound-absorbing layer behind it and be absorbed, without being reflected back in large quantities.

[0022] The upper inner surface of the soundproof enclosure 3 is provided with a top plate sound-absorbing layer, which includes a damping rubber plate 10 and a porous rock wool plate 9. The damping rubber plate 10 and the porous rock wool plate 9 are sequentially arranged on the top inner surface of the soundproof enclosure 3. A spacer layer 14 is provided between the porous rock wool plate 9 and the damping rubber plate 10. The spacer layer 14 is an air spacer layer with a semi-vacuum state inside, which absorbs low-frequency vibrations. After the damping rubber plate 10 and the porous rock wool plate 9 are installed, the air inside them is extracted, making the spacer layer 14 a semi-vacuum state. Several honeycomb-shaped grooves are opened on the outer side of the porous rock wool plate 9 to increase the area for noise absorption.

[0023] The porous rock wool board 9 is the innermost layer directly facing the noise source. Its interior is filled with a large number of interconnected honeycomb micropores. When sound waves enter, air molecules rub against each other in the micropores and convert sound energy into heat energy, thereby achieving efficient absorption of high-frequency noise. The porous rock wool board 9 is provided with a spacer layer 14. This cavity structure forms a resonant sound-absorbing structure for specific low-frequency noise generated by the vibration system, which can significantly improve the absorption effect of the device on low-frequency roaring sound. The damping rubber plate 10 uses its high quality and high damping characteristics to reflect and block sound waves.
