Description

Technical Field

[0001] The utility model relates to the field of ventilation devices, and specifically to a ventilation device for a silkworm egg drying room. Background Technique

[0002] Silkworm eggs are the eggs laid by silkworms. Silkworm eggs include original grandparent eggs, original parent eggs, basic eggs, and first-generation hybrid eggs. The production of silkworm eggs mainly includes silkworm egg breeding, refrigeration, acid dipping, stimulation, and disinfection by bathing, etc. After acid dipping and disinfection by bathing of silkworm eggs, the silkworm eggs need to be placed in a ventilated place to dry.

[0003] Currently, when drying silkworm eggs, a fan is usually used to blow. However, the place directly blown by the fan dries quickly, while the place not blown by the fan dries slowly. This will result in uneven air drying of the silkworm eggs, thus affecting the development of silkworm eggs and bringing certain inconvenience and influence to the production of silkworm eggs.

[0004] Therefore, in view of the above problems, a ventilation device for a silkworm egg drying room is proposed. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A ventilation device for a silkworm egg drying room of the utility model includes a silkworm egg drying room body; a connecting plate is fixedly connected to the middle of the silkworm egg drying room body; a motor is fixedly connected to the middle of the connecting plate; an adjusting component is fixedly connected to the output end of the motor; a disc is fixedly connected to the middle of the adjusting component; the disc and the motor are eccentrically arranged; a sliding plate is slidably connected to the middle of the silkworm egg drying room body; a telescopic plate is fixedly connected to the middle of the sliding plate; the telescopic plate and the disc are fixedly connected; a wind pipe is fixedly connected to the middle of the sliding plate; the wind pipe is located inside the silkworm egg drying room body; the wind pipe and the silkworm egg drying room body are slidably connected; a plurality of air vents are opened in the middle of the wind pipe. The wind pipe and the sliding plate will slide along the silkworm egg drying room body under the rotation of the telescopic plate driven by the disc, so that the air flow will diffuse at different heights inside the silkworm egg drying room body, improving the uniformity of the air flow distribution inside the silkworm egg drying room body, increasing the contact area between the air flow and the silkworm eggs, and shortening the time required for the device to dry the silkworm eggs.

[0007] Preferably, the adjusting component includes a fixing plate; a screw rod is rotatably connected to the inner side wall of the fixing plate; a slider is threadedly connected to the middle of the screw rod; the slider and the disc are fixedly connected; the slider and the disc are eccentrically arranged; by rotating the screw rod, the slider drives the disc to move together to adjust the eccentric distance between the disc and the motor, realizing the adjustment of the moving distance of the wind pipe by the device, so that the wind pipe can dry the silkworm eggs at different heights inside the silkworm egg drying room body, further improving the drying speed of the device for the silkworm eggs.

[0008] Preferably, a plurality of damping springs are symmetrically and fixedly connected to the middle of the sliding plate; the ends of adjacent damping springs are fixedly connected with pressing plates; the middle of the silkworm egg drying room body is symmetrically and fixedly connected with baffles; the pressing plates are located between a pair of baffles; when the staff adjusts the screw rod, the amplitude of the reciprocating movement of the sliding plate and the air duct will become larger and larger. When the sliding plate moves, it will drive the damping springs and the pressing plates to move together. When the air duct is about to collide with the remaining hanging parts inside the silkworm egg drying room body during the movement, the pressing plate will collide with the baffle, and then the pressing plate will transfer the pressure to the damping spring. The damping spring will be compressed and absorb the impact, and then the damping spring will transfer the attenuated impact force to the sliding plate and the telescopic plate, reducing the impact force received when the sliding plate moves too large, and also reducing the collision of the air duct with other components when moving inside the silkworm egg drying room body.

[0009] Preferably, a vertical rod is fixedly connected to the middle of the pressing plate; the end of the vertical rod is sharp; an air bag is fixedly connected to the middle of the pressing plate; the vertical rod and the air bag are correspondingly arranged; the vertical rod and the air bag are located between a pair of pressing plates; when the pressing plate collides with the baffle, it will move towards the sliding plate together with the damping spring. When the pressing plate moves, it will drive the vertical rod or the air bag to move together and make their distances closer. When the vertical rod and the air bag come into contact, the vertical rod will pierce the air bag. When the air bag is damaged, it will make a sound, enabling the staff to know immediately that the air duct is about to collide with other components, and improving the stability of the air duct for drying the silkworm eggs inside the silkworm egg drying room body.

[0010] Preferably, a plurality of flow dividing plates are fixedly connected to the middle of the air duct; a plurality of round holes are opened in the middle of the flow dividing plates; after the air flow sprays out from the air outlet, it will reach the inside of the flow dividing plates, and then the air flow will flow out from each round hole, enabling the air flow to flow and diffuse in multiple directions, accelerating the air flow speed inside the silkworm egg drying room body and shortening the time required for drying the silkworm eggs.

[0011] Preferably, a pull rope is fixedly connected to the inner side wall of the air outlet; a spherical ball is fixedly connected to the end of the pull rope; the spherical ball and the round hole are correspondingly arranged; when the air duct reciprocates along the silkworm egg drying room body, the air outlet will drive the pull rope to move together. The pull rope will drive the spherical ball to swing irregularly under the action of inertia. When the spherical ball swings, it will continuously contact and close a plurality of round holes. Since the total air flow rate inside the flow dividing plate remains unchanged, the air flow rate at the other round holes will increase, and finally the air flow rate ejected from the round holes will continuously change, further accelerating the air flow speed inside the silkworm egg drying room body.

[0012] Preferably, a plurality of brush hairs are fixedly connected to the middle of the spherical ball; the brush hairs are arranged in a circumferential array; when the spherical ball swings, it will drive the brush hairs to move together.

When the disc 15 rotates, it will deviate from the center of the motor 13 and drive the telescopic plate 17 to move together. The length of the telescopic plate 17 will change with the horizontal position change of the disc 15, and at the same time, the height of the telescopic plate 17 will also move together with the vertical position movement of the disc 15. The telescopic plate 17 will drive the sliding plate 16 to make a reciprocating movement so that the sliding plate 16 slides along the silkworm egg drying room body 1. When the sliding plate 16 moves, it will drive the wind pipe 18 to slide along the surface of the silkworm egg drying room body 1 together. When the wind pipe 18 moves, it will drive the air outlets 19 to move together, so that the air flow will diffuse and flow at different heights inside the silkworm egg drying room body 1 until the silkworm eggs inside the silkworm egg drying room body 1 are air-dried; the wind pipe 18 and the sliding plate 16 will slide along the silkworm egg drying room body 1 together with the telescopic plate 17 under the rotation of the disc 15, so that the air flow will diffuse at different heights inside the silkworm egg drying room body 1, improving the uniformity of the air flow distribution inside the silkworm egg drying room body 1, increasing the contact area between the air flow and the silkworm eggs, and shortening the time required for the device to air-dry the silkworm eggs.

At this time, the distance of the reciprocating movement of the slide plate 16 and the air duct 18 along the silkworm egg drying room body 1 will also change. Finally, the airflow ejected from the air outlet 19 will accurately cover the area of the height where the silkworm eggs are located; by rotating the screw rod 22 to make the slider 23 drive the disc 15 to move together to adjust the eccentric distance between the disc 15 and the motor 13, the device can adjust the moving distance of the air duct 18, so that the air duct 18 can dry the silkworm eggs at different heights in the silkworm egg drying room body 1, and further improve the drying speed of the device for the silkworm eggs.

[0027] Please refer to Figures 2 to 4 As shown in the figure, a plurality of damping springs 3 are symmetrically and fixedly connected to the middle of the slide plate 16; the ends of adjacent damping springs 3 are fixedly connected with a pressing plate 32; the middle of the silkworm egg drying room body 1 is symmetrically and fixedly connected with a baffle 33; the pressing plate 32 is located between a pair of baffles 33; when the user adjusts the screw rod 22, the amplitude of the reciprocating movement of the slide plate 16 and the air duct 18 will become larger and larger. When the slide plate 16 moves, it will drive the damping springs 3 and the pressing plate 32 to move together. When the air duct 18 is about to collide with the other hanging parts inside the silkworm egg drying room body 1 during the moving process, the pressing plate 32 will collide with the baffle 33, and then the pressing plate 32 will transfer the pressure to the damping springs 3. The damping springs 3 will be compressed and absorb the impact, and then the damping springs 3 will transfer the attenuated impact force to the slide plate 16 and the telescopic plate 17, reducing the impact force received when the moving amplitude of the slide plate 16 is too large, and also reducing the situation of the air duct 18 colliding with other components when moving inside the silkworm egg drying room body 1.

[0028] Please refer to Figure 4 As shown in the figure, a vertical rod 4 is fixedly connected to the middle of the pressing plate 32; the end of the vertical rod 4 is sharp; an air bag 42 is fixedly connected to the middle of the pressing plate 32; the vertical rod 4 and the air bag 42 are correspondingly arranged; the vertical rod 4 and the air bag 42 are located between a pair of pressing plates 32; when the pressing plate 32 collides with the baffle 33, it will move towards the slide plate 16 together with the damping spring 3. When the pressing plate 32 moves, it will drive the vertical rod 4 or the air bag 42 to move together and make their distances closer. When the vertical rod 4 and the air bag 42 come into contact, the vertical rod 4 will pierce the air bag 42, and when the air bag 42 is damaged, it will make a sound, so that the staff can know immediately that the air duct 18 is about to collide with other components, improving the stability of the air duct 18 for drying the silkworm eggs in the silkworm egg drying room body 1.

[0029] Please refer to Figure 5 As shown, a plurality of flow dividing plates 5 are fixedly connected to the middle of the air duct 18; a plurality of round holes 52 are formed in the middle of the flow dividing plate 5; after the air flow sprays out from the air outlet 19, it will reach the inside of the flow dividing plate 5, and then the air flow will flow out from each round hole 52, so that the air flow can flow and diffuse in multiple directions, accelerating the air flow speed in the silkworm egg drying room body 1 and shortening the time required for air-drying the silkworm eggs.

[0030] Please refer to Figure 5 As shown, a pull rope 6 is fixedly connected to the inner side wall of the air outlet 19; a spherical ball 62 is fixedly connected to the end of the pull rope 6; the spherical ball 62 and the round hole 52 are correspondingly arranged; when the air duct 18 reciprocates along the silkworm egg drying room body 1, the air outlet 19 will move together with the pull rope 6, and the pull rope 6 will drive the spherical ball 62 to swing irregularly under the action of inertia. When the spherical ball 62 swings, it will continuously contact and close the plurality of round holes 52. Because the total air flow in the flow dividing plate 5 remains unchanged, the air flow at the other round holes 52 will increase, and finally the air flow sprayed out from the round holes 52 will continuously change, further accelerating the air flow speed in the silkworm egg drying room body 1.

[0031] Please refer to Figure 5 As shown, a plurality of brush hairs 7 are fixedly connected to the middle of the spherical ball 62; the brush hairs 7 are arranged in a circumferential array; when the spherical ball 62 swings, it will drive the brush hairs 7 to move together, and when the brush hairs 7 move, they will contact the round holes 52 and clean the impurities attached to the inner walls of the round holes 52, improving the convenience of cleaning the round holes 52 by the device.

[0032] Working principle: Start the motor 13 so that the motor 13 drives the adjustment component 14 and the disc 15 to rotate. At the same time, connect an external fan to the air duct 18 so that the air flow will enter the interior of the air duct 18 and be ejected from the air outlet 19. When the disc 15 rotates, it will deviate from the center of the motor 13 and drive the telescopic plate 17 to move together. The length of the telescopic plate 17 will change with the horizontal position change of the disc 15, and at the same time, the height of the telescopic plate 17 will also move together with the vertical position movement of the disc 15. The telescopic plate 17 will drive the sliding plate 16 to make a reciprocating movement so that the sliding plate 16 slides along the silkworm egg drying house body 1. When the sliding plate 16 moves, it will drive the air duct 18 to slide along the surface of the silkworm egg drying house body 1. When the air duct 18 moves, it will drive the air outlet 19 to move together, so that the air flow will diffuse and flow at different heights in the silkworm egg drying house body 1 until the silkworm eggs in the silkworm egg drying house body 1 are dried; when the height difference of the silkworm eggs placed in the silkworm egg drying house body 1 is large or small, the staff can rotate the screw rod 22 so that the slider 23 slides along the screw rod 22. The slider 23 will drive the disc 15 to move together, so that the distance between the center of the disc 15 and the motor 13 changes. At this time, the distance of the reciprocating movement of the sliding plate 16 and the air duct 18 along the silkworm egg drying house body 1 will also change. Finally, the air flow ejected from the air outlet 19 will accurately cover the area at the height where the silkworm eggs are located; when the staff adjusts the screw rod 22, the amplitude of the reciprocating movement of the sliding plate 16 and the air duct 18 will become larger and larger. When the sliding plate 16 moves, it will drive the damping spring 3 and the pressing plate 32 to move together. When the air duct 18 is about to collide with the other hanging parts inside the silkworm egg drying house body 1 during the movement process, the pressing plate 32 will collide with the baffle 33. Then, the pressing plate 32 will transfer the pressure to the damping spring 3. The damping spring 3 will be compressed and absorb the impact. Then, the damping spring 3 will transfer the attenuated impact force to the sliding plate 16 and the telescopic plate 17; when the pressing plate 32 and the baffle 33 collide, they will move towards the sliding plate 16 together with the damping spring 3. When the pressing plate 32 moves, it will drive the vertical rod 4 or the air bag 42 to move together and make their distances closer. When the vertical rod 4 and the air bag 42 come into contact, the vertical rod 4 will pierce the air bag 42. When the air bag 42 is damaged, it will make a sound, so that the staff can know immediately that the air duct 18 is about to collide with other components; after the air flow is ejected from the air outlet 19, it will reach the inside of the flow dividing plate 5. Then, the air flow will flow out from each round hole 52, so that the air flow can flow and diffuse in multiple directions, accelerating the air flow speed inside the silkworm egg drying house body 1; when the air duct 18 reciprocates along the silkworm egg drying house body 1, the air outlet 19 will drive the pull rope 6 to move together. The pull rope 6 will drive the ball 62 to swing irregularly under the action of inertia. When the ball 62 swings, it will continuously contact and close multiple round holes 52. Because the total air flow volume in the flow dividing plate 5 remains unchanged, the air flow volume at the other round holes 52 will increase. Finally, the air flow volume ejected from the round holes 52 will change continuously;When the spherical ball 62 swings, it will drive the brush bristles 7 to move together. When the brush bristles 7 move, they will come into contact with the round hole 52 and clean the impurities adhering to the inner wall of the round hole 52.
